Full Text Available Background and purpose: This study aimed to manage medical errors before and after the implementation of accreditation in public, private, and social security hospitals of Mazandaran, Iran. Materials and Methods: This descriptive study has been done in 38 hospitals. Data were collected through documents reviewed relating to 2013 and 2014. The paired t-test and Friedman test were used by statistical software SPSS. Results: Results showed that the most and the least percent of reported errors, before accreditation, in sequence, were related to public clinical unit (55.9% and operating rooms (0.6%, and after accreditation in public clinical unit (46.6% and operating rooms (2.3% in teaching centers. The most errors (before accreditation occurred in the morning (62% and the least, in the evening (8.3% in teaching centers. Furthermore, after accreditation, the most errors occurred in the morning (64.8% and the least, in the night (17.3% in therapeutic hospitals. Paired t-test showed that there is no significant difference between medical errors before and after accreditation. Friedman test showed that structural/systemic errors reported were the most important medical errors in teaching centers after accreditation and therapeutic hospitals before accreditation (P < 0.05. Conclusion: There is no significant difference between the rate of reported errors before and after the implementation of accreditation. This illustrates that the role of management in controlling of medical errors has been poor, and stronger management should be applied in providing health care services.

Endocan has been shown to be a marker for several cancers and may show degree of malignancy. The aim of this study is to assess serum levels of endocan before and after surgery on low-grade gliomas (LGGs). Endocan was assayed by commercially available enzyme-linked immunosorbent assay (ELISA) kits in a total of 19 patients and 12 controls. Serial serum samples were obtained before and after surgery (1 st day, 1 st week, and 1 st month of surgery). Control samples were collected from cord blood during cesarean section. The results were compared with control brain tissues. Controls showed significantly lower serum endocan levels compared to before and after surgery ( P < 0.05). There is a trend of increase in mean serum levels from before surgery and during the very early period after surgery (during first week); however, in the first month, mean serum levels became lower. Endocan, a vital molecule for angiogenesis, is highly expressed before and after surgery in LGGs, but long-term data is needed. Furthermore, future studies should include high-grade gliomas to discuss whether endocan is associated with recurrence and response to treatment.

Gastroesophageal scintigraphy is a quantitative technique that can be employed to detect and quantitate gastroesophageal reflux before and after the application of therapeutic modalities, including change in body position, bethanechol, atropine, antacids, and antacid-alginate compounds. Five groups of 10-15 patients each were studied before and after using each therapeutic modality and before and after atropine. The results were compared to the patient's symptomatology and to the acid reflux test. Gastroesophageal scintigraphy was performed following oral administration of 300 microCi 99mTc-sulfur colloid in 300 ml acidified orange juice. Thirty-second gamma camera images were obtained as the gastroesophageal gradient was increased from approximately 10 to 35 mm Hg at 5 mm Hg increments using an inflatable abdominal binder. Data were processed using a digital computer. Reflux was reduced by change in position from recumbent to upright, and by the use of subcutaneous bethanechol, oral antacid, or oral antacidalginate compound. Atropine increased reflux. Gastroesophageal scintigraphy is more sensitive than fluoroscopy, correlates well with clinical symptomatology, and is a reliable and convenient technique for the quantitative estimation of reflux before and after therapy

Few data exist on interruptions in the drug-use process in hospital pharmacies and their effects on patient care. The primary objective was to compare the hourly number of stimuli received and emitted (i.e., generated) by pharmacists and pharmacy technicians before and after implementation of measures intended to reduce interruptions. The secondary objective was to evaluate the impact of the corrective measures on 4 specific stimuli. This before-and-after cross-sectional observational study was conducted in the main dispensing area of the pharmacy department of a Canadian university hospital centre. Stimuli received and emitted by pharmacists and pharmacy technicians were counted before (2010) and after (2012) implementation of corrective measures designed to limit interruptions. The effect of corrective measures on targeted stimuli was measured with a t test. Data were collected during a total of 93 randomly scheduled 30-min observation periods: 62 periods in 2010 (n = 2663 stimuli) and 31 periods in 2012 (n = 1217 stimuli). The average hourly stimulus rate (± standard deviation) was unchanged after implementation of corrective measures: 85.9 ± 22.2 in 2010 and 78.5 ± 20.1 in 2012 (p = 0.06). However, a significant decline was observed for many individual stimuli, including the number of face-to-face nonprofessional conversations among pharmacists (4.4 ± 4.2 in 2010 versus 1.2 ± 1.8 in 2012, p = 0.003). Despite the implementation of corrective measures, there was no statistically significant change in the hourly stimulus rates from 2010 to 2012. Other studies are needed to better characterize the nature and repercussions of stimuli, distractions, and interruptions.

Radiofrequency (RF) ablation of accessory pathways in Wolff-Parkinson-White (WPW) syndrome is supposed to be less aggressive than fulguration while providing excellent results. The aims of our study were therefore the evaluation of the functional results of this therapy in terms of left or right ejection fractions and its effects on the contraction synchronism between both ventricular chambers, derived from bi-ventricular Fourier phase histograms. A consecutive series of 44 patients has been investigated within 48 hours before and after RF therapy: 14 patients had right sided WPW and 30 patients left sided WPW. Only patients for whom RF treatment was considered as a success have been included in the study. Gated blood pool tomography has been performed in order to localize the site of pre-excitation and to build-up the phase histograms for both ventricles, and planar gated imaging has been used for right and left ejection fraction determination. Functional results demonstrate the absence of deleterious effect of RF on ventricular contraction and rather a slight increase of ejection fractions, with a more statistically significant difference for left WPW (LVEF = 62.2 % before RF vs 64.4 % after RF; p = 0.02) than for right WPW (RVEF = 36.3 % before RF vs 39.7 after RF; p = 0.16). Phase analysis, on the contrary, show only significant differences for right WPW, with a noticeable decrease of the pre-excitation (left-to-right phase difference 14.4 deg before RF vs 7.5 deg after RF; p = 0.03) and a significant reduction of the right ventricular phase dispersion (right phase standard deviation 26.5 deg before RF vs 19.0 deg after RF; p = 0.03). For left WPW no measurable differences can be demonstrated in the basal state and it is suggested to use stimulation techniques in order to enhance the competition between the normal and accessory conduction pathways.

This study was conducted to evaluate the microbiomes of endodontic-periodontal lesions before and after chemomechanical preparation (CMP). Clinical samples were taken from 15 root canals (RCs) with necrotic pulp tissues and from their associated periodontal pockets (PPs) (n = 15) of teeth with endodontic-periodontal lesions before and after CMP. The Human Oral Microbe Identification using Next Generation Sequencing (NGS) protocol and viable culture were used to analyze samples from RCs and PPs. The Mann-Whitney U test and Benjamini-Hochberg corrections were performed to correlate the clinical and radiographic findings with microbial findings (P Bacteria were detected in 100% of the samples in both sites (15/15) using NGS. Firmicutes was the most predominant phylum in both sites using both methods. The most frequently detected species in the RCs before and after CMP using NGS were Enterococcus faecalis, Parvimonas micra, Mogibacterium timidum, Filifactor alocis, and Fretibacterium fastidiosum. The species most frequently detected in the PPs before and after CMP using NGS were P. micra, E. faecalis, Streptococcus constellatus, Eubacterium brachy, Tannerella forsythia, and F. alocis. Associations were found between periapical lesions ≤ 2 mm and Desulfobulbus sp oral taxon 041 and with periodontal pockets ≥ 6 mm and Dialister invisius and Peptostreptococcus stomatis (all P periodontal lesions is complex and more diverse than previously reported. It is important to note that bacteria do survive in some root canals after CMP. Finally, the similarity between the microbiota of both sites, before and after CMP, suggests there may be a pathway of infection between the pulp and periodontium.

Hospital procedures have been associated with cognitive change in older patients. This study aimed to document the prevalence of mild cognitive impairment in individuals undergoing left heart catheterization (LHC) before the procedure and the incidence of cognitive decline to 3 months afterwards. We conducted a prospective, observational, clinical investigation of elderly participants undergoing elective LHC. Cognition was assessed using a battery of written tests and a computerized cognitive battery before the LHC and then at 3 months afterwards. The computerized tests were also administered at 24 hours (or discharge) and 7 days after LHC. A control group of 51 community participants was recruited to calculate cognitive decline using the Reliable Change Index. Of 437 participants, mild cognitive impairment was identified in 226 (51.7%) before the procedure. Computerized tests detected an incidence of cognitive decline of 10.0% at 24 hours and 7.5% at 7 days. At 3 months, written tests detected an incidence of cognitive decline of 13.1% and computerized tests detected an incidence of 8.5%. Cognitive decline at 3 months using written tests was associated with increasing age, whereas computerized tests showed cognitive decline was associated with baseline amnestic mild cognitive impairment, diabetes mellitus, and prior coronary stenting. More than half the patients aged >60 years presenting for LHC have mild cognitive impairment. LHC is followed by cognitive decline in 8% to 13% of individuals at 3 months after the procedure. Subtle cognitive decline both before and after LHC is common and may have important clinical implications. URL: www.anzctr.org.au. Unique identifier: ACTRN12607000051448. © 2018 The Authors.

Full Text Available Background. Levothyroxine is commonly used in the treatment of patients with hypothyroidism. Levothyroxine is most often administered in the morning, on an empty stomach, in order to increase its oral absorption. However, many patients have difficulties taking levothyroxine in the morning. Aim. The aim of this study was evaluating the effect of changing levothyroxine administration time from before breakfast to before dinner on the serum levels of TSH and T4. Subjects and Methods. Fifty patients between 18 and 75 years old with hypothyroidism were included in the study and were randomly divided into two groups. Each group received two tablets per day (one levothyroxine tablet and one placebo tablet 30 minutes before breakfast and 1 hour before dinner. After two months, the administration time for the tablets was changed for each group, and the new schedule was continued for a further two-month period. The serum TSH and T4 levels were measured before and after treatment in each group. Results. Changing the levothyroxine administration time resulted in 1.47 ± 0.51 µIU/mL increase in TSH level (p=0.001 and 0.35 ± 1.05 µg/dL decrease in T4 level (p=0.3. Conclusions. Changing the levothyroxine administration time from before breakfast to before dinner reduced the therapeutic efficacy of levothyroxine.

To evaluate CT density of liver changes between before and after amiodarone administration. Twenty-five patients underwent non-enhanced CT including the liver before and after amiodarone administration. We set regions of interest (ROIs) at liver S8, spleen, paraspinal muscle, and calculated average CT density in these ROIs, then compared CT density between liver and other organs. Statistical differences between CT density of liver and various ratios before and after administration were determined, along with correlations between cumulative dose of amiodarone and liver density after administration, density change of liver, and various ratios after administration. Liver density, liver-to-spleen ratio, and liver-to-paraspinal muscle ratio differed significantly between before and after amiodarone administration. No significant correlations were found between cumulative doses of amiodarone and any of liver density after administration, density change of liver, or various ratios after administration. CT density of liver after amiodarone administration was significantly higher than that before administration. No correlations were identified between cumulative dose of amiodarone and either liver density after administration or density change of liver. Amiodarone usage should be checked when radiologists identify high density of the liver on CT.

The change of vertical hydraulic conductivity ( K v) before and after a flood season is crucial in understanding the long-term temporal variation of streambed permeability. Therefore, in this study, a detailed K v field investigation was conducted at an in-channel site within the Dawen River, China, before and after a flood season. In-situ falling-head permeameter tests were performed for the determination of K v. The tests were conducted using a 10 × 10 grid, at five different depths. In total, 871 valid K v values from layers 1-5 were obtained. The Kruskal-Wallis test on these K v values before and after the flood season shows they belonged to different populations. The sediments before the flood season primarily consisted of sand and gravel, whereas after the flood season, patchy distribution of silt/clay occurred in the sandy streambed and silt/clay content increased with the increasing depth; under the losing condition during flooding, downward movement of water brought fine particles into the coarse sediments, partially silting the pores. Accordingly, the K v values after the flood season had a smaller mean and median, and a higher level of heterogeneity, compared to those before the flood season. Additionally, the distribution pattern in K v across the stream differed before and after flood season; after the flood season, there was an increasing trend in K v from the south bank to the north bank. Overall, the contrasts of K v before and after the flood season were predominantly subject to the infiltration of fine particles.

Mechanical forces in orthodontic treatment used to treat malocclusion can cause inflamed gingival tissue and the process of tooth movement may resorb dental root. Root resorption is an iatrogenic effect of orthodontic treatment but it can be monitored using protein biomarker. This study aims to investigate the differences of protein profile before and after orthodontic treatment using different staining methods. Human gingival crevicular fluid and saliva were collected from orthodontic patients before and after treatment. Protein profile were observed using SDS-PAGE. Our study shows down regulation of proteins after 3 months of treatment. Hence, there are potential values from this study to aid in investigation for specific biomarkers for root resorption.

Full Text Available Objective Evaluation of exercise effects in racehorses is important in horseracing industry and animal health care. In this study, we compared metabolic patterns between before and after exercise to screen metabolic biomarkers for exercise effects in thoroughbreds. Methods The concentration of metabolites in muscle, plasma, and urine was measured by 1H nuclear magnetic resonance (NMR spectroscopy analysis and the relative metabolite levels in the three samples were compared between before and after exercise. Subsequently, multivariate data analysis based on the metabolic profiles was performed using orthogonal partial least square discriminant analysis (OPLS-DA and variable important plots and t-test was used for basic statistical analysis. Results From 1H NMR spectroscopy analysis, 35, 25, and 34 metabolites were detected in the muscle, plasma, and urine. Aspartate, betaine, choline, cysteine, ethanol, and threonine were increased over 2-fold in the muscle; propionate and trimethylamine were increased over 2-fold in the plasma; and alanine, glycerol, inosine, lactate, and pyruvate were increased over 2-fold whereas acetoacetate, arginine, citrulline, creatine, glutamine, glutarate, hippurate, lysine, methionine, phenylacetylglycine, taurine, trigonelline, trimethylamine, and trimethylamine N-oxide were decreased below 0.5-fold in the urine. The OPLS-DA showed clear separation of the metabolic patterns before and after exercise in the muscle, plasma, and urine. Statistical analysis showed that after exercise, acetoacetate, arginine, glutamine, hippurate, phenylacetylglycine trimethylamine, trimethylamine N-oxide, and trigonelline were significantly decreased and alanine, glycerol, inosine, lactate, and pyruvate were significantly increased in the urine (p<0.05. Conclusion In conclusion, we analyzed integrated metabolic patterns in the muscle, plasma, and urine before and after exercise in racehorses. We found changed patterns of metabolites in

This study assessed the presence of specific antibodies for coeliac disease in outpatients suffering from eating disorders before and after nutritional intervention. We also evaluated whether those patients should undergo regular screening for coeliac disease. The sample consisted of 154 patients with a mean age of 16.7 years - ranging from one to 19 years of age - suffering from eating disorders. Serology screening for coeliac disease and total immunoglobulin A (IgA) levels was evaluated in the 154 children before the nutritional intervention and in 104 patients after the intervention. The patients consumed an adequate amount of gluten in both phases. Postintervention evaluation revealed that 92 patients (88.5%) achieved a normal body weight, while the remaining 12 (11.5%) became obese. Postprandial abdominal discomfort and pain were resolved. The serology tests were negative in all patients, before and after intervention. None displayed IgA deficiency. To the best of our knowledge, this was the first prospective study where patients underwent a screening serology for coeliac disease before and after nutritional intervention. No indication of the coexistence of eating disorders and coeliac disease was documented, and the patients in our study were unlikely to require regular screening for coeliac disease. ©2015 Foundation Acta Paediatrica.

A CMOS matrix for extracting MOSFET parameters before and after irradiation

International Nuclear Information System (INIS)

Blaes, B.R.; Buehler, M.G.; Lin, Y.S.; Hicks, K.A.

1988-01-01

An addressable matrix of 16 n- and 16 p-MOSFETs has been designed to extract the DC MOSFET parameters for all dc gate bias conditions before and after irradiation. The matrix contains four sets of MOSFETs each with four different geometries that can be biased independently before and after irradiation. Thus the worst-case bias scenarios can be determined. The MOSFET matrix was fabricated at a silicon foundry using a radiation-soft CMOS p-well LOCOS process. Cobalt 60 irradiation results for the n-MOSFETs showed a very low threshold voltage shift of -3mV/krad(Si); whereas, the p-MOSFETs showed 21 mV/krad(Si). The worst-case threshold voltage shift occurred for the n-MOSFET with a gate bias of 5V during anneal, but for the p-MOSFETs, biasing did not affect the shift in the threshold voltage. A parasitic MOSFET dominated the leakage of the n-MOSFET biased with 5V on the gate during irradiation

Protein content of leaf-cutting ant queens before the nuptial flight and during the post-claustral phase

Full Text Available Protein content of leaf-cutting ant queens before the nuptial flight and during the post-claustral phase. This study evaluated the crude protein content of queens of Atta sexdens before the nuptial flight and after the claustral phase in laboratory and field colonies. The hypothesis was that protein is used for survival of the queen and for early colony growth during the claustral phase. Additionally, the nest morphology, live biomass and adult population of field colonies were evaluated. Crude protein was determined by digestion of the organic material with sulfuric acid at high temperatures. The mean crude protein content was 123.23 ± 11.20 mg for females before the nuptial flight and 70.44 ± 12.21 mg for laboratory-reared queens after the claustral phase. The post-claustral crude protein content of field-collected queen was 55.90 ± 9.18 mg. With respect to the loss of crude protein as a function of duration of the claustral phase, laboratory-reared queens lost 52.79 mg and field-collected queens lost 67.33 mg compared to females before the nuptial flight. A positive linear correlation was observed between the weight of field-collected queens (256.4 ± 36.3 mg and colony biomass (13.02 ± 9.12 g, but there was no correlation between biomass and nest depth (13.11 ± 3.82 cm. As expected, the present results support the hypothesis that protein is used for survival of the queen and for early colony growth, as demonstrated by the reduction in crude protein content as a function of duration of the claustral phase. To our knowledge, this is the first study to provide data of the dynamics of protein reserves in leaf-cutting ant queens during the claustral phase.

To evaluate usefulness of MR in assessment of tumor response to the chemotherapy, we prospectively studied cases of cervical carcinoma with more than 2.5cm in diameter or stage IIb or more. Three courses of chemotherapy were performed with cisplatin and 5 F-U. MR images were obtained both before and after chemotherapy. Nine of 13 patients were undertaken radical hysterectomy after chemotherapy and MR amination. MR volumetry, stage and depth of stromal invasion were compared before and after chemotherapy. And in 9 patients who underwent radical hysterectomy, comparison of pathologic and MR imaging findings were also done. The results were following. 1) All tumors dectrased in volume (m = 80.5%). 2) Five tumors (38.5%) reduced in stage, IB → CIS (1); IIA → CIS (1), IIA → IB (2), IIB → IB (1). 3) Depth of stromal invasion in MRI correlated well with that of histopathologic specimen in 7 of the 9 patients. Conclusively MR imaging is useful in assessment of tumor response to chemotherapy

Computerised order sets have the potential to reduce clinical variation and improve patient safety but the effect is variable. We sought to evaluate the impact of changes to the design of an order set on the delivery of chlorhexidine mouthwash and hydroxyethyl starch (HES) to patients in the intensive care unit. The study was conducted at University Hospitals Bristol NHS Foundation Trust, UK. Our intensive care unit uses a clinical information system (CIS). All drugs and fluids are prescribed with the CIS and drug and fluid charts are stored within a database. Chlorhexidine mouthwash was added as a default prescription to the prescribing template in January 2010. HES was removed from the prescribing template in April 2009. Both interventions were available to prescribe manually throughout the study period. We conducted a database review of all patients eligible for each intervention before and after changes to the configuration of choices within the prescribing system. 2231 ventilated patients were identified as appropriate for treatment with chlorhexidine, 591 before the intervention and 1640 after. 55.3% were prescribed chlorhexidine before the change and 90.4% after (p<0.001). 6199 patients were considered in the HES intervention, 2177 before the intervention and 4022 after. The mean volume of HES infused per patient fell from 630 mL to 20 mL after the change (p<0.001) and the percentage of patients receiving HES fell from 54.1% to 3.1% (p<0.001). These results were well sustained with time. The presentation of choices within an electronic prescribing system influenced the delivery of evidence-based interventions in a predictable way and the effect was well sustained. This approach has the potential to enhance the effectiveness of computerised order sets.

Physics before and after Einstein

CERN Document Server

Capria, M Mamone

2005-01-01

It is now a century ago that one of the icons of modern physics published some of the most influential scientific papers of all times. With his work on relativity and quantum theory, Albert Einstein has altered the field of physics forever. It should not come as a surprise that looking back at Einstein''s work, one needs to rethink the whole scope of physics, before and after his time. This books aims to provide a perspective on the history of modern physics, spanning from the late 19th century up to today. It is not an encyclopaedic work, but it presents the groundbreaking and sometimes provocative main contributions by Einstein as marking the line between ''old'' and ''new'' physics, and expands on some of the developments and open issues to which they gave rise.

This paper presents an Empirical Bayes before-after evaluation of the road safety effects of a new motorway (freeway) in Østfold county, Norway. The before-period was 1996-2002. The after-period was 2009-2015. The road was rebuilt from an undivided two-lane road into a divided four-lane road. The number of killed or seriously injured road users was reduced by 75 percent, controlling for (downward) long-term trends and regression-to-the-mean (statistically significant at the 5 percent level; recorded numbers 71 before, 11 after). There were small changes in the number of injury accidents (185 before, 123 after; net effect -3%) and the number of slightly injured road users (403 before 279 after; net effect +5%). Motorways appear to mainly reduce injury severity, not the number of accidents. The paper discusses challenges in implementing the Empirical Bayes design when less than ideal data are available.

Full Text Available Background One of the objectives of the health transformation plan (HTP in Iran is to reduce out-of-pocket (OOP payments for inpatient services and eradicate informal payments. The HTP has three phases: the first phase (launched in May 5, 2014 is focused on reducing OOP payments for inpatient services; the second phase (launched in May 22, 2014 is focused on primary healthcare (PHC and the third phase utilizes an updated relative value units for health services (launched in September 29, 2014 and is focused on the elimination of informal payments. This aim of this study was to determine the OOP payments and the frequency of informal cash payments to physicians for inpatient services before and after the HTP in Kurdistan province, Iran. Methods This quasi-experimental study used multistage sampling method to select and evaluate 265 patients discharged from hospitals in Kurdistan province. The study covered 3 phases (before the HTP, after the first, and third phases of the HTP. Part of the data was collected using a hospital information system form and the rest were collected using a questionnaire. Data were analyzed using Fisher exact test, logistic regression, and independent samples ttest. Results The mean OOP payments before the HTP and after the first and third phases, respectively, were US$59.4, US$17.6, and US$14.3 in hospital affiliated to the Ministry of Health and Medical Education (MoHME, US$39.6, US$33.7, and US$13.7 in hospitals affiliated to Social Security Organization (SSO, and US$153.3, US$188.7, and US$66.4 in private hospitals. In hospitals affiliated to SSO and MoHME there was a significant difference between the mean OOP payments before the HTP and after the third phase (P < .05. The percentage of informal payments to physicians in hospitals affiliated to MoHME, SSO, and private sector, respectively, were 4.5%, 8.1%, and 12.5% before the HTP, and 0.0%, 7.1%, and 10.0% after the first phase. Contrary to the time before the HTP

Gun violence is related to substantial morbidity and mortality with surrounding discussions framed and shaped by the media. This study’s objective was to explore national news media’s reporting of gun violence around a mass shooting. National news pieces were coded according to categories of gun violence, media frames, entities held responsible, responses, and reporting of the public heath approach. Individuals were held responsible for gun violence in 63% of pieces before and 32% after the shooting. Lawmakers were held responsible in 30% of pieces before and 66% after. Background checks were a proposed gun violence prevention method in 18% of pieces before and 55% after Sandy Hook, and lethality reduction of firearms was in 9% before and 57% after. Following a mass shooting, the media tended to hold government, not individuals, primarily responsible. The media often misrepresented the real picture of gun violence and key public health roles.

The aim of this study was to investigate the incidence of self-reported infectious episodes (IE) during 3 weeks before (pre-IE) and 3 weeks after (post-IE) a marathon race and relate these figures to training status, running time, socioeconomic and demographic factors. Two questionnaires, including questions about important factors for IE incidence, were given to a representative cohort of 1694 runners (17% of all finishers) in the Stockholm Marathon 2000. Pre-IE incidence in the cohort was 17% with no difference between women and men. Post-IE incidence in the whole cohort was 19% with no significant (P>0.05) difference between women and men. The post-IE incidence in runners without a pre-IE was 16% (P>0.05 to pre-IE incidence). In the group of runners with pre-IE, 33% experienced an IE after the race also (Ptraining volume 6 months before the race, finishing time and socioeconomic and demographic factors and pre-IE or post-IE. This study does not support the theory of increased infection rate after exhaustive long-distance running ("The Open Window Theory") in recreational runners, but suggests that the sometimes experienced increased rate of infections among athletes can be caused by strenuous exercise too soon after an infection.

Full Text Available This study presents the evolution of agricultural production of Zaire before and after 1960 with the help of variable quantifies of products, the cultured area and the exported quantifies of products. A comparative analysis of quantifies of studied products shows that after 1960, the agricultural production of basis foodstuffs of the Zairian population has fallen of the order of 91 % in comparison with the first period. This study shows that the system of peasantry introduced in 1936 by the INEAC, the rationalization of cultural methods connected to the governmental explain the agricultural expansion of Zaire before 1960.

Detecting critical state before phase transition of complex biological systems by hidden Markov model.

Science.gov (United States)

Chen, Pei; Liu, Rui; Li, Yongjun; Chen, Luonan

2016-07-15

Identifying the critical state or pre-transition state just before the occurrence of a phase transition is a challenging task, because the state of the system may show little apparent change before this critical transition during the gradual parameter variations. Such dynamics of phase transition is generally composed of three stages, i.e. before-transition state, pre-transition state and after-transition state, which can be considered as three different Markov processes. By exploring the rich dynamical information provided by high-throughput data, we present a novel computational method, i.e. hidden Markov model (HMM) based approach, to detect the switching point of the two Markov processes from the before-transition state (a stationary Markov process) to the pre-transition state (a time-varying Markov process), thereby identifying the pre-transition state or early-warning signals of the phase transition. To validate the effectiveness, we apply this method to detect the signals of the imminent phase transitions of complex systems based on the simulated datasets, and further identify the pre-transition states as well as their critical modules for three real datasets, i.e. the acute lung injury triggered by phosgene inhalation, MCF-7 human breast cancer caused by heregulin and HCV-induced dysplasia and hepatocellular carcinoma. Both functional and pathway enrichment analyses validate the computational results.

The role of plasma adiponectin (ADPN) in patients with impaired kidney function and following kidney transplantation (Tx) is debated. We aimed to: (i) determine whether pretransplant ADPN level is an independent risk factor for deterioration of glucose tolerance including development of new......-onset diabetes mellitus after Tx, (ii) describe which parameters that influence the ADPN concentration before and after Tx. Fifty-seven nondiabetic kidney allograft recipients and 40 nondiabetic uraemic patients were included. The Tx group was examined at baseline and 3 and 12 months after Tx. The uraemic...... analysis, whereas an ordinal logistic regression analysis revealed no predictive characteristic of ADPN for aggravation of the glucose tolerance after Tx. In conclusion, kidney transplantation is accompanied by a significant reduction in ADPN concentration. Several factors determine the ADPN concentration...

To evaluate the effects of airborne-particle abrasion (APA) and Er,Cr:YSGG laser irradiation on 4-point-flexural strength, phase transformation and morphologic changes of zirconia ceramics treated at pre-sintered or post-sintered stage. Three hundred and forty-two bar shaped zirconia specimens were milled with different sizes according to the flexural strength test (n = 10), X-ray diffraction (XRD) (n = 4) and field emission scanning electron microscope (FE-SEM) (n = 4) analyses. For each test protocol, specimens were divided into 4 main groups whether the surface treatments applied before or after sintering and whether the specimens received heat treatment or not as pre-sintered, post-sintered no-heat and post-sintered heat-treated groups, and a group was served as control. Main groups were further divided into 6 equal subgroups according to surface treatment method applied (2 W-, 3 W-, 4 W-, 5 W-, 6 W-laser irradiations and APA). Surface treatments were applied to pre-sintered groups before sintering and to post-sintered groups after sintering. Post-sintered heat-treated groups were subjected to veneer ceramic firing simulation after surface treatments. Flexural strength and flexural modulus values were statistically analysed and monoclinic phase content was calculated. Weibull analysis was used to evaluate strength reliability and fractographic analysis was conducted. Highest flexural strength values were detected at post-sintered no-heat APA and 4W-laser groups (P SEM images pre-sintered groups. Application of surface treatments at pre-sintered stage may be detrimental for zirconia ceramics in terms of flexural strength. Treating the surface of zirconia ceramic before sintering process is not recommended due to significant decrease in flexural strength values. 2 W-4 W Er,Cr:YSGG laser irradiations can be regarded as alternative surface treatment methods when zirconia restoration would be subjected to veneer ceramic firing procedures

Full Text Available Posing research questions is the central ability of the scientific thought. This article examines the ability of sixth grade children to pose researchable questions before and after a three months’ work on a didactic sequence based on the inquiry school model. According to their purpose, the questions asked by children, after reading a text, were classified into researchable questions -susceptible to be empirically explored-, questions about a cause, and questions on a piece of data. The results show that the amount and the type of questions the students were able to pose during the intervention changed, from most of questions on data or information, to most of researchable questions, subsequently, the importance of designing teaching approaches to foster this ability was proved.

Comparison of doses, before and after remedial action

International Nuclear Information System (INIS)

Wallo, A. III

1988-01-01

The Division of Facility and Site Decommissioning Projects at DOE-Headquarters is evaluating potential doses from vicinity properties before and after remedial action at several sites using the RESRAD computer code. A preliminary review was completed for nineteen Colonie vicinity properties. This review indicated potential doses before remedial action at these sites ranged from about 43 to 2 mrem/year and after remediation between 5 and 0 mrem/year. These estimates indicate the conservatism in the DOE-derived soil decontamination remedial action. Following remedial action, the potential doses are on the order of those being considered to be below regulatory concern by EPA and NRC. The estimates made for these sites are still conservative due to the method used to determine the source term. More realistic assessments of source terms are anticipate dot significantly affect the after-remedial-action doses, possibly lowering them all to below 1 mrem/year. This evaluation is being refined with more realistic estimates of the source term, for all of the Colonie vicinity properties. Once the Colonie vicinity properties are completed, at least three other sites will be evaluated. It is hoped that this information will provide added confidence in the remedial action guidelines and more general acceptance of the guidelines by the EPA and others

We studied constipation-related health care among children before and after constipation admission. Index admissions for constipation in 2010-2011 were identified in the Truven Marketscan Database, which includes children receiving Medicaid in 10 states. We measured number of and spending for outpatient constipation visits 12 months before and after index hospitalizations. We also measured spending for constipation hospitalizations and rehospitalization rate. There were 780 index constipation admissions. The median number of outpatient constipation visits was 1 (interquartile range [IQR] = 0, 3) in the 12 months before and 2 (IQR [0, 4]) after admission ( P = .001). Median outpatient spending for constipation was $110 (IQR [0, 429]) before and $132 (IQR [0, 431]) after admission ( P = .2). Median spending for index constipation admissions was $5295 (IQR [2756, 8267]); 78 children (10%) were rehospitalized for constipation within 12 months. Constipation-related health care utilization increased after constipation admission. Median spending for one constipation admission was 50 times the median spending for 12 months of outpatient constipation visits.

To evaluate how many patients could have undergone partial nephrectomy (PN) rather than radical nephrectomy (RN) before and after neoadjuvant axitinib therapy, as assessed by five independent urological oncologists, and to study the variability of inter-observer agreement. Pre- and post-systemic treatment computed tomography scans from 22 patients with clear cell renal cell carcinoma in a phase II neoadjuvant axitinib trial were reviewed by five independent urological oncologists. R.E.N.A.L. nephrometry score and κ statistics were calculated. The median R.E.N.A.L. nephrometry score changed from 11 before treatment to 10 after treatment (P = 0.002). Five tumours with moderate complexity before axitinib treatment remained moderate complexity after treatment. Of 17 tumours with high complexity before axitinib treatment, three became moderate complexity after treatment. The overall κ statistic was 0.611. Moderate-complexity κ was 0.611 vs a high-complexity κ of 0.428. Before axitinib treatment the κ was 0.550 vs 0.609 after treatment. After treatment with axitinib, all five reviewers agreed that only five patients required RN (instead of eight before treatment) and that 10 patients could now undergo PN (instead of three before treatment). The odds of PN feasibility were 22.8-times higher after treatment with axitinib. There is considerable variability in inter-observer agreement on the feasibility of PN in patients treated with neoadjuvant targeted therapy. Although more patients were candidates for PN after neoadjuvant axitinib therapy, it remains difficult to identify these patients a priori. © 2015 The Authors BJU International © 2015 BJU International Published by John Wiley & Sons Ltd.

BACKGROUND Pain associated with coxarthrosis, typically occurring in middle-aged and elderly patients, very commonly causes considerable limitation of motor fitness and dependence on pharmacotherapy. This article provides an assessment of a rehabilitation program with tailored water exercises in patients with osteoarthritis before and after total hip replacement. MATERIAL AND METHODS A total of 192 patients (the mean age 61.03±10.89) suffering from hip osteoarthritis (OA) were evaluated before and after total hip replacement (THR). The clinical study covered measurements of hip active ranges of motion (HAROM) and the forces generated by pelvis stabilizer muscles. Pain intensity was assessed according to analogue-visual scale of pain (VAS) and according to the Modified Laitinen Questionnaire. The patients were divided into 6 groups (4 treatment and 2 control). We compared 2 rehabilitation programs using kinesitherapy and low-frequency magnetic field. One of them also had specially designed exercises in the water. Statistical analysis was carried out at the significance level α=0.05. This was a cross-sectional study. RESULTS A positive effect of water exercises on a number of parameters was found in patients with OA both before and after total hip replacement surgery. We noted a significant reduction of pain (pwater exercises most significantly reduced pain in patients with OA before and after total hip replacement surgery. 2. Inclusion of water exercises in a rehabilitation program can reduce the use of medicines in patient with OA and after THR.

Full Text Available This study was aimed at elaborating students’ perception toward the implementation of peer assessment in writing class either before or after revision. Writing becomes one of skills which should be mastered by students in order to get higher level of literacy. Writing is a productive skill which asks students to arrange words and organize them into good writing which could be understood by readers. The success of writing is determined by the writing process itself starting from planning, first draft writing, revising, and editing. One of the strategies used in teaching writing is by implementing peer assessment. Peer assessment strategy becomes one of important parts in the process of writing because there will be feedback or suggestion from peers in doing a review. The number of the subject of this research was students in second semester of the English Education Department of UNISNU Jepara. This research was conducted on even semester. The total number of the students, which became respondents, was 37 students of English Education Department. The research design used was qualitative research which measured students’ perceptions of the implementation of peer assessment in writing: before and after revision. The result showed that before revision, students had negative perception toward their own writing. After revision, they had positive perceptions toward peer assessment strategy. Those included usefulness and meaningfulness, nature of feedback, reality of feedback, precision, validity, fairness, and personal goal-setting. Besides that, the score after revision (7.9 was higher than the score before revision (6.62. It meant that the result showed the increasing of students’ score after revision.

To assess the deficiencies and potential areas through a medical audit of the emergency departments, in six general hospitals affiliated to Shahid Beheshti University of Medical Sciences at Tehran, Iran, after preparing specific wards-based international standards. A checklist was completed for all hospitals which met our eligibility criteria mainly observation and interviews with head nurses and managers of the emergency medicine unit of the hospitals before (2003) and after (2008) the establishment of emergency departments there. Domains studied included staffing, education and continuing professional development (CPD), facility (design), equipment, ancillary services, medical records, manuals and references, research, administration, pre-hospital care, information systems, disaster planning, bench-marking and hospital accreditation. Education and CPD (p = 0.042), design and facility (p = 0.027), equipment (p = 0.028), and disaster (p = 0.026) had significantly improved after the establishment of emergency departments. Nearly all domains showed a positive change though it was non-significant in a few. In terms of observation, better improvement was seen in disaster, security, design, and research. According to the score for each domain compared to what it was in the earlier phase, better improvement was observed in hospital accreditation, information systems, security, disaster planning, and research. Security, disaster planning, research, design and facility had improved in hospitals that wave studied, while equipment, records, ancillary services, administration and bench-marking had the lowest improvement even after the establishment of emergency department, and, hence, needed specific attention.

The aim of this study was to determine 31 PMRS reference spectrum and intracellular pH of calf muscles in the dominant limb of healthy, young, male volunteers before and after intense physical effort. Examinations were performed with a 1.5 T MR system. FID CSI (Free Induction Decay Chemical Shift Imaging) sequence was used with the following parameters: TR=4000 ms, FA=90°, NEX=2 and VOI (Volume Of Interest)=8×8×8 cm 3 (512 cm 3 ) involving in calf muscles. Raw data was preprocessed using SAGE (GE) software. Authors analyzed relative concentrations ratios of selected metabolites: PCr/ATP and PCr/P i . Intracellular pH and relative concentrations ratios of each metabolite (P i , PCr, α-ATP, β-ATP, γ-ATP, ATP) were also calculated relative to the sum of concentrations of all metabolites. Results were compared with a t-test. Based on statistical analysis of results significant differences (p<0.05) were demonstrated for some of the studied metabolites and for intracellular pH. Increase in PCr concentration in relation to the sum of concentrations of all metabolites and to ATP concentration was noted. However, β-ATP, α-ATP and ATP concentrations relative to the sum of concentrations of all metabolites become reduced. Decrease in pH after physical effort was demonstrated. There were no significant differences (p<0.05) in concentrations of remaining metabolites before and after exercise. Increase in PCr concentration relative to P i concentration and decrease of P i and γ-ATP concentration relative to the sum of concentrations of all metabolites were demonstrated. The 31 PMRS method enables assessment of concentrations of phosphorus-containing metabolites as well as intercellular pH before and after exercise. This method is still under examination, but it has already shown promise as a diagnostic tool for the future

Full Text Available The poultry industry normally has little control over the raw material that arrives at the processing plant. This experiment aimed to evaluate chemical and energetic quality of corn obtained in a feed mill before and after pre-cleaning. Twenty samples of 30 kg of corn each were taken from trucks delivering corn to the mill. The trucks were then unloaded and the material passed through a pre-cleaning process when another sample was taken. Samples were graded and physical properties evaluated: density (g/L, grain percentages of foreign material, impurities, fragments, broken, soft, insect damaged, fire-burnt, fermented, damaged, cracked and fine particles, as well as chemical composition analysis: Apparent metabolizable energy for poultry (AME, ether extract (EE, crude fiber (CF, starch (STA, water activity (WA, crude protein (CP, digestible and total lysine, methionine, cystine, threonine, tryptophan, valine, isoleucine, leucine, phenylalanine, histidine and arginine. The experiment was a randomized design with two treatments (before and after pre-cleaning and twenty replications. Data was analyzed using SAS ® and treatment differences obtained using F test. Correlations and principal components were calculated. There was a decrease in density after the pre-cleaning process, which was probably due to the removal of earth and stones rather than grain and its fractions. Significant increases were found for insect damage, fermented and damaged grain while fire-burn was significantly reduced after the pre-cleaning process. Starch increased after pre-cleaning which is a result of contaminants that normally are poor in this carbohydrate, but fiber levels increased too. Apparent metabolizable energy, aminoacids, digestible (P<0.05 and total (P<0.05 histidine, total lysine and methionine (P<0.1 levels were reduced after pre-cleaning. Density was higher when there were fewer impurities such as straw, husk or small grains. Broken corn was positively

The objective of the study was to measure vaginal pressure during various daily activities in patients before and after vaginal surgery for pelvic organ prolapse, searching data for evidence-based activity guidelines. Vaginal pressure (VP) was studied in 23 patients during activities such as rest......, pelvic floor contraction (PFC), coughing, Valsalva, rising from sitting to standing and lifting 2 and 5 kg with four different lifting techniques. VP was measured before, 1-5 days and 4-6 weeks after vaginal repair. Mean VP was four to five times higher during coughing and Valsalva compared to PFC...... was not related to the type of vaginal repair. The results imply that post-operative counselling should concentrate more on treating chronic cough and constipation than restrictions of moderate physical activities....

Periodontal disease is among the most common inflammatory conditions which is associated with many different factors. One of the contributing factors to the pathogenesis of this condition may compromise the defensive mechanism of antioxidants. The present study evaluates the antioxidant capacity of saliva in periodontal patients before and after periodontal treatment. In this cross sectional study, 31 patients systemically healthy non smokers with chronic periodontitis were recruited. The antioxidant capacity of saliva was measured before the initial phase of periodontal therapy and after completion of the treatment. Data were analyzed using SPSS 19 software. Paired T-Test, Independent sample T-test and ANOVA tests were used as appropriated. The mean and standard deviation antioxidant capacity of the saliva after the treatment.(0.962± 0.287µM)was significantly higher than before the treatment (0.655 ± 0.281 µM ,pperiodontal treatment was higher among men than among women; however, the difference was not significant (P=0.07). The mean difference of salivary antioxidant capacity was not significantly differed among different ages (P=0.772). The antioxidant capacity of saliva was higher after periodontal therapy among patients with periodontal disease, however the change was not varied across the ages and gender. Therefore, the alterations in the defensive mechanism of antioxidants could be the key factors contribute to the pathogenesis of periodontal diseases.

variables. Methods. Analysis of patients participating in a 12-week exercise-based outpatient cardiac rehabilitation program (OCR between April 1999 and December 2007. Exercise capacity (ExC and quality of life including sexual function were assessed before and after OCR. Results. Complete data were available in 896 male patients. No sexual activity at all was indicated by 23.1% at baseline and 21.8% after OCR, no problems with sexual activity by 40.8% at baseline and 38.6% after OCR. Patients showed an increase in specific problems (erectile dysfunction and lack of orgasm from 18% to 23% (<.0001 during OCR. We found the following independent positive and negative predictors of sexual problems after OCR: hyperlipidemia, age, CABG, baseline ExC and improvement of ExC, subjective physical and mental capacity, and sense of affiliation. Conclusions. Sexual dysfunction is present in over half of the patients undergoing OCR with no overall improvement during OCR. Age, CABG, low exercise capacity are independent predictors of sexual dysfunction after OCR.

Background Electronic prescribing system implementation is recommended to improve patient safety and general practitioner's discharge information communication. There is a paucity of information about hospital staff perspectives before and after system implementation. Objective To explore hospital staff views regarding prescribing and discharge communication systems before and after hospital electronic prescribing and medicines administration (HEPMA) system implementation. Setting A 560 bed United Kingdom district general hospital. Methods Semi-structured face-to-face qualitative interviews with a purposive sample of hospital staff involved in the prescribing and discharge communication process. Interviews transcribed verbatim and coded using the Framework Approach. Behavioural aspects mapped to Theoretical Domains Framework (TDF) to highlight associated behavioural change determinants. Main outcome measure Staff perceptions before and after implementation. Results Nineteen hospital staff (consultant doctors, junior doctors, pharmacists and advanced nurse practitioners) participated before and after implementation. Pre-implementation main themes were inpatient chart and discharge letter design and discharge communication process with issues of illegible and inaccurate information. Improved safety was anticipated after implementation. Post-implementation themes were improved inpatient chart clarity and discharge letter quality. TDF domains relevant to staff behavioural determinants preimplementation were knowledge (task or environment); skills (competence); social/professional roles and identity; beliefs about capabilities; environmental context and resources (including incidents). An additional two were relevant post-implementation: social influences and behavioural regulation (including self-monitoring). Participants described challenges and patient safety concerns pre-implementation which were mostly resolved post-implementation. Conclusion HEPMA implementation

The use of radiological activity in the operating room (OR) and a regulatory decrease of the eye lens dose warrant an assessment of how medical staff are protected from radiation. This study aims to evaluate practices and knowledge in radiation protection (RP) for OR doctors before and after training. A descriptive study of surgeons and anesthetists in a French public hospital center was conducted in 2016. An ad hoc questionnaire concerning occupational practices and knowledge about RP was distributed before and one month after RP training. Among 103 doctors attending the training, 90 answered the questionnaire before the training. Results showed a lack of knowledge and good practice in RP. Most of the participants (86.7%) had never been trained in RP and recognized insufficient knowledge. Most of them (92.2%) wore a lead apron, 50.0% a thyroid-shield, 5.6% lead glasses, 53.3% a passive dosimeter and 17.8% an electronic dosimeter. None of them benefitted from collective protective equipment such as a ceiling suspended screen. The questionnaire following the training was completed by only 35 doctors. A comparison before and after training results showed an improvement in knowledge (scores of correct responses: 5.5/16 before and 9.5/16 after training) but not in RP good practices (scores of correct responses: 3.2/7 before and 3.3/7 after training). One training session appears to be insufficient to improve the application of the safety rules when x-rays are used. Communication needs to be improved regarding RP among anesthetists and surgeons, such as training renewal, workstation analysis in OR related to x-ray use and occupational medical follow-up. Otherwise, radiological risks in OR need to be given better consideration, such as radio-induced cataract risk. It is necessary to encourage the use of dosimeters and protective equipment and to strengthen access to lead glasses and collective protective equipment, such as ceiling suspended screens. All these

2017-06-01

This study investigates the impact of energy renovation on the indoor air quality of an apartment building during the heating season. The study was performed in one residential building before and after its renovation. An evaluation of the indoor air quality was performed using objective measurements and a subjective survey. The concentration of CO2 was measured in the bedrooms, and a sampling of the total volatile compounds (TVOC) was performed in the living rooms of the selected apartments. Higher concentrations of CO2 and TVOC were observed in the residential building after its renovation. The concentrations of CO2, and TVOC in some of the cases exceeded the recommended maximum limits, especially after implementing energy-saving measures on the building. The average air exchange rate was visibly higher before the renovation of the building. The current study indicates that large-scale renovations may reduce the quality of an indoor environment in many apartments, especially in the winter season.

Liver transplantation has become the treatment of choice for patients with end-stage liver disease. Most studies show a positive effect on quality of life after liver transplantation, but most studies are based on data from Western countries and little is known about quality of life in liver transplant recipients in Turkey or other developing countries. To investigate liver transplant recipients' quality of life and factors affecting it, before and 3 months after transplantation in western Turkey. Descriptive and comparative, with data collected prospectively. Two medical centers in Western Turkey. Sixty-five adult recipients of a liver transplant between May 15 and December 31,2007. Quality of life was measured by using the Nottingham Health Profile Turkish version, and sociodemographic and clinical data were collected from patients' records. Scores on all subscales of the Nottingham Health Profile differed significantly from before to after liver transplantation. The differences between the mean scores for quality of life before and after transplantation varied significantly with the patients' sex and disease severity.

Spousal similarity in life satisfaction before and after divorce.

Wortman, Jessica; Lucas, Richard E

2016-04-01

Previous research has explored possible origins of individual differences in subjective well-being, focusing largely on stable, internal characteristics of traits as predictors of life satisfaction (Diener & Lucas, 1999). Although past work has demonstrated that life satisfaction is largely stable over the life span, other evidence has also demonstrated the lasting impact of life events. In this study, we use married couples as a test of the impact of life circumstances on life satisfaction, focusing on similarity in life satisfaction before and after divorce. If life satisfaction is impacted by shared life circumstances, married couples (who share life circumstances) should show greater similarity in life satisfaction before divorce than after. We tested this possibility using a dyadic latent-state-trait model that examined cross-spouse similarity in the stable and changing components of life satisfaction. Using a nationally representative panel study from Germany (Wagner, Frick & Schupp, 2007), we showed that similarity declined substantially following divorce. This suggests that life satisfaction is related to shared life circumstances. (c) 2016 APA, all rights reserved).

Some reports have described pleural lavage cytology (PLC) to be a prognostic factor for non-small cell lung cancer (NSCLC) patients. However, there have only been a few reports describing the findings both immediately after thoracotomy (PLC after thoracotomy) and before the closure of the chest (PLC before closure). From April 2002 to April 2008, both PLC after thoracotomy and PLC before closure were performed in 296 consecutive patients who underwent resections for NSCLC. PLC after thoracotomy was positive in 14 patients. The survival rate in the PLC after thoracotomy positive cases was significantly poorer than in PLC after thoracotomy negative cases (P=0.047). In contrast, there were 26 PLC before closure positive cases. The survival rate in the PLC before closure positive cases was significantly poorer than in the PLC before closure negative cases (PPLC after thoracotomy is not an independent prognostic factor in our study. However, PLC before closure was an independent prognostic factor based on multivariate analyses. We conclude that PLC before closure was found to be a better prognostic factor than PLC after thoracotomy for NSCLC patients.

Flotation performances and surface properties of chalcopyrite with xanthate collector added before and after grinding

Science.gov (United States)

Peng, Huiqing; Wu, Di; Abdelmonem, Mohamed

In this study, effects of the collector added before grinding and after grinding on the subsequent flotation and mineral surface properties were investigated. The pH was controlled at 10 during the grinding and flotation processes opened to the atmosphere. With enough amounts of sodium butyl xanthate addition, adding the collector before grinding recovered more chalcopyrite than adding it after grinding in single mineral flotation. The Eh of each ground pulp before and after conditioning were measured and it was found that adding collector before grinding obtained higher and relatively suitable pulp potential for chalcopyrite flotation. Particle size analyses of the flotation products indicate that the different flotation recoveries occurred due to the different flotation losses in fine particles (flotation feedings and found that more carbon and oxygen, and less iron were remained on mineral surfaces when the collector was added before grinding, due to the higher collector adsorption capacity, larger free oxygen adsorbance and less iron oxide/hydroxide species.

The aim of this study was to assess the changes in the power Doppler sonographic findings in patients with oral cancer undergoing chemotherapy and radiotherapy. We performed US examinations on 187 cervical lymph nodes (71 metastatic and 116 reactive nodes) excised from 52 patients before and after preoperative therapy. On Power Doppler images, we calculated the vascular index (VI) and evaluated the vascular pattern. We also assessed the diagnostic power using receiver operating characteristic (ROC) curve analysis. Irradiation caused an increase of the VI and better visualization of the vessels within the lymph node in the reactive nodes; however, in the metastatic nodes, the VI was not significantly different between that before and after irradiation. When the reader observed the images before irradiation, the area under an ROC curve (Az values) observed by B-mode sonography were closely similar to those obtained by B-mode plus power Doppler sonography. With both images before and after irradiation, the Az value obtained by B-mode plus power Doppler sonography was higher than that by B-mode sonography alone. After irradiation, the enhanced Doppler signals contributed to a better visualization of the vessels and a better detection of any vascular abnormalities. (orig.)

Full Text Available Abstract Background Many colic horses are compromised due to the disease state and from hours of starvation and sometimes long trailer rides. This could influence their muscle energy reserves and affect the horses' ability to recover. The principal aim was to follow metabolic parameter before, during, and up to 7 days after anaesthesia in healthy horses and in horses undergoing abdominal surgery due to colic. Methods 20 healthy horses given anaesthesia alone and 20 colic horses subjected to emergency abdominal surgery were anaesthetised for a mean of 228 minutes and 183 minutes respectively. Blood for analysis of haematology, electrolytes, cortisol, creatine kinase (CK, free fatty acids (FFA, glycerol, glucose and lactate was sampled before, during, and up to 7 days after anaesthesia. Arterial and venous blood gases were obtained before, during and up to 8 hours after recovery. Gluteal muscle biopsy specimens for biochemical analysis of muscle metabolites were obtained at start and end of anaesthesia and 1 h and 1 day after recovery. Results Plasma cortisol, FFA, glycerol, glucose, lactate and CK were elevated and serum phosphate and potassium were lower in colic horses before anaesthesia. Muscle adenosine triphosphate (ATP content was low in several colic horses. Anaesthesia and surgery resulted in a decrease in plasma FFA and glycerol in colic horses whereas levels increased in healthy horses. During anaesthesia muscle and plasma lactate and plasma phosphate increased in both groups. In the colic horses plasma lactate increased further after recovery. Plasma FFA and glycerol increased 8 h after standing in the colic horses. In both groups, plasma concentrations of CK increased and serum phosphate decreased post-anaesthesia. On Day 7 most parameters were not different between groups. Colic horses lost on average 8% of their initial weight. Eleven colic horses completed the study. Conclusion Colic horses entered anaesthesia with altered

Background The Netherlands was the first country in the world to implement a Euthanasia Act in 2002. It is unknown whether legalising euthanasia under strict conditions influences the number and nature of euthanasia requests. Aim To investigate changes in the number of, and reasons for, requests for euthanasia in Dutch general practice after implementation of the Euthanasia Act. Design of study Retrospective dynamic cohort study comparing 5 years before (1998–2002) and 5 years after (2003–2007) implementation of the Act. Method Standardised registration forms were used to collect data on requests for euthanasia via the Dutch Sentinel Practice Network. This network of 45 general practices is nationally representative by age, sex, geographic distribution, and population density. Results The mean annual incidence of requests before implementation amounted to 3.1/10 000 and thereafter to 2.8/10 000 patients. However, trends differed by sex. The number of requests by males decreased significantly from 3.7/10 000 to 2.6/10 000 (P = 0.008); the requests by females increased non-significantly from 2.6/10 000 to 3.1/10 000. Before and after implementation, cancer remained the major underlying disease for requesting euthanasia: 82% versus 77% for men; 73% versus 75% for females. Pain was a major reason for a request, increasing in the period before implementation (mean 27%), but declining in the period thereafter (mean 22%). Loss of dignity became a less important reason after implementation (from 18% to 10%, P = 0.04), predominantly due to a marked decrease in the number of females citing it as a reason (from 17% to 6%, P = 0.02). Conclusion There was no increase in demand for euthanasia after implementation of the Euthanasia Act. Pain as a reason for requesting euthanasia showed an increasing trend before implementation, but declined thereafter. Loss of dignity as a reason declined, especially in females. PMID:20353671

Dual isotope gastric emptying studies were performed on 16 morbidly obese patients before and after gastroplasty to determine the effect of this surgery on the rate of emptying. The solid and liquid phases of gastric emptying were compared with a normal control group. In the 900-g and 50-g meals there was a significant difference in the mean half emptying time between solid and liquid phases of emptying (p less than 0.05). Pre-operatively, the 900-g meal half emptying times of both solids and liquids and the 50-g liquid phase meal did not differ significantly between obese patients and the control group. However, in the solid phase of the 50-g meal obese patients differed significantly from a control group (p = 0.007). Three months after gastroplasty, gastric emptying of 50-g meals from the total stomach was not significantly changed from the pre-operative 50-g meal values in ten of 12 patients (p less than 0.05) and no change in total stomach emptying times were seen at 12 mo compared to the 3-mo study (p less than 0.05). Emptying of the pouch alone for both solids and liquids was significantly faster than the pre-operative and postoperative total stomach studies. Gastric emptying in the obese is normal with large meals, but is delayed in small meals. In most patients, gastroplasty does not result in slower emptying of meals.

EPR study on tomatoes before and after gamma-irradiation

2009-01-01

The results from the EPR studies on fresh, air-dried and lyophilized tomato samples before and after gamma-irradiation are reported. Before irradiation fresh and air-dried tomatoes exhibit one singlet EPR line characterized with common g-factor of 2.0048±0.0005, whereas freeze-dried tomato does not show any EPR spectrum. After irradiation, a typical 'cellulose-like' triplet EPR spectrum appears in all samples, attributed to cellulose free radicals, generated by gamma-irradiation. It consists of intense central line with g=2.0048±0.0005 and two weak satellite lines separated ca. 3 mT left and right of it. In air-dried and lyophilized tomatoes the 'cellulose-like' EPR spectrum is superimposed by an additional partly resolved carbohydrate spectrum. Fading measurements of the radiation-induced EPR signals indicate that the intensity of the EPR spectra of air-dried and freeze-dried tomato are reduced to about 50% after 50 days, whereas those of fresh irradiated tomatoes kept at 4 o C fade completely in 15 days. The reported results unambiguously show that the presence of two satellite lines in the EPR 'cellulose-like' spectra of tomato samples can be used for identification of radiation processing.

This study was undertaken to evaluate 99m Tc-DTPA renography before and after extracorporeal shock wave lithotripsy (ESWL). Twelve patients with renal calculi were examined in this study. In three patients, bilateral kidneys were treated with ESWL. Sequential renal images of the vascular phase, and the functional and excretory phases were taken using a gamma camera (ZLC 7500, Siemens), after intravenous injection of 555 MBq of 99m Tc-DTPA. Renograms were generated using data stored every 10 seconds for a period of 30 minutes by computer (Scintipac-2400, Shimadzu). Some treated kidneys were enlarged and/or showed uniform retention of radioactivity on sequential images, within a week after ESWL. Renogram patterns after ESWL were varied in each patient. The renogram findings after ESWL seemed to be affected by the presence or absence of stone fragments in the urinary tract. (author)

2004-01-01

To identify evidence-based, best practice strategies for managing the ocular surface and tear film before, during, and after laser in situ keratomileusis (LASIK). After a comprehensive review of relevant published literature, evidence-based recommendations for best practice management strategies are presented. Symptoms of ocular irritation and signs of dysfunction of the integrated lacrimal gland/ocular surface functional gland unit are common before and after LASIK. The status of the ocular surface and tear film before LASIK can impact surgical outcomes in terms of potential complications during and after surgery, refractive outcome, optical quality, patient satisfaction, and the severity and duration of dry eye after LASIK. Before LASIK, the health of the ocular surface should be optimized and patients selected appropriately. Dry eye before surgery and female gender are risk factors for developing chronic dry eye after LASIK. Management of the ocular surface during LASIK can minimize ocular surface damage and the risk of adverse outcomes. Long-term management of the tear film and ocular surface after LASIK can reduce the severity and duration of dry eye symptoms and signs. Strategies to manage the integrated ocular surface/lacrimal gland functional unit before, during, and after LASIK can optimize outcomes. As problems with the ocular surface and tear film are relatively common, attention should focus on the use and improvement of evidence-based management strategies.

Kobayashi, Y; Shiga, H

1991-01-01

To understand functions of the masticatory system accurate recording and analysis of mandibular movement are indispensable. The purpose of this experiment was to find functional differences in the path of masticatory movement due to experimental occlusal interference. Occlusal interference was placed on the mandibular first molar or cuspid of the habitual chewing side in seven normal subjects. While subjects were asked to masticate gum on one side at a time, jaw movements were recorded and analyzed using an automatic masticatory movement analysis system previously developed. Standard deviations (SD) of the vertical and lateral elements in the opening and closing phases were calculated and compared before and after the occlusal interference. In the opening phase the SDs increased significantly with either the interference placed on the cuspid or molar tooth. In the closing phase it generally increased with either the interference. The effect was significantly more with the cuspid interference than that of the molar tooth. The SD of the vertical element is also generally increased with either interference. However, in contrast to the lateral element, the effect of the molar interference on the vertical element was significantly more than that of the cuspid.

Extracorporeal shock wave lithotripsy (ESWI.) with adjunctive oral litholytic therapy has proven to be a useful treatment in selected patients with gallbladder stones. To study the effect of ESWL on gallbladder dynamics, {sup 99m}Tc-DISIDA hepatobiliary scintigraphy was done for 25 patients with symptomatic gallstones and 10 normal controls. Of these 25 patients, 15 were treated with ESWL and adjunctive oral litholytic agents (ESWL group) and 10 were treated only with oral litholytic agents (UDCA group). After overnight fast and gallbladder visualization on a routine hepatobiliary scintigraphy with 7 mCi of {sup 99m}Tc-DISIDA, subjects were given fatty meal and imaged with a gamma camera interfaced to a computer (I frame/minute for 70 minutes). A gallbladder time-activity curve was generated and latent period (LP), ejection period (EP), ejection fraction (EF) and ejection rate (ER) were calculated, ESWL group were studied before, l day after and 2 weeks after ESWL, and UDCA group were studied before and 2 weeks after starting oral medication Mean basal EF was significantly reduced in patients but other parameters were not reduced. In ESlVL group, mean EF and mean ER at 1 day after ESWL were reduced. In 3 of them, gallbladder was not visualized at all. Two weeks after ESWL, however, all parameters were recovered to basal level. In UDCA group, all parameters were not changed significantly during medication. We can conclude that ESWL has such immediate adverse effect on gallbladder dynamics as reducing contractility and nonvisualization of gallbladder but it has no long-term effect.

The purpose of this study was to analyze the CT findings of hepatoblastoma before and after chemotherapy, and to compare them with surgical and pathologic features. Twelve hepatoblastoma patients underwent chemotherapy prior to surgery; in all cases, CT scanning was performed before and after chemotherapy. We reviewed the findings with special attention to changes in tumor volume, the extent and pattern of contrast enhancement, the extent of low-attenuation area in the tumor, the presence of a septum, and calcification or ossification or ossification within the mass before and after chemotherapy. Post-chemotherapy CT findings were compared with operative and pathologic findings. After chemotheapy, the volume of the tumor mass decreased in all patients, and the extent of involved segments decreased in nine (75%), the non-enhancing area within the mass, on the other hand, increased in nine (75 %). On pre-chemotherapy CT, calcifications were detected in seven patients (58%), and on post-chemotherapy CT, in nine (75%); the extent of calcification were detected in seven patients. On the basis of CT findings, viable tumor and necrosis areas could not be distinguished. Massive calcification or osteoid mixed with loose connective tissue was noted in the mesenchymal component of the tumor; the whirling pattern of enhancement within the area of low density seen on CT scanning corresponded to osteoid mixed with loose connective tissue, which contained rich blood vessels. We describe the CT findings of hepatoblastoma both before and after chemotherapy, highlighting the changes which occurred. An understanding of these changes is helpful for the proper management of this condition. (author). 18 refs., 1 tab., 5 figs

Lifestyle modification programs are different but typically include both nutritional aspects and physical activity as main domains with different behavioral and/or psychological strategies designed to affect change. A fundamental role in modifying unhealthy habits is played by personal motivation for change. The present study sought to investigate, in a group of 100 overweight/obese outpatients with and/or without TMD2, treatment seeking, the effect of an intensive lifestyle program on medical measures and motivational profile for physical activity (PA) and healthy nutrition (NUTR). Subjects participated in an intensive multidisciplinary lifestyle intervention at C.U.R.I.A.MO. Before and after the intervention, patients received a comprehensive evaluation of their clinical, anthropometric, and metabolic states and motivation to lifestyle changes. Data showed differences before and after intervention in both medical and motivational measures. Before the intervention patients reported to be ready, open, and determined to change and gave importance to healthy habits. After the intervention patients continued to be determined but increased the actions toward the change showing a higher degree of maintenance and of acquisition of habits especially in the physical domain of the new lifestyle. Data support the notion that the motivation should be followed during all the lifestyle interventions to support the change on both domains of the lifestyle program.

The present study is to investigate the quality changes of ginseng stems and leaves before and after frost. The contents changes of ginsenoside, free amino acid, and total phenolic compounds, as well as DPPH radical scavenging effect before and after frost were measured. The content of 9 ginsenoside monomer in ginseng stems was decreased except for Rg, and Re after frost, but in ginseng leaves was all decreased. The total content of amino acids was decreased in ginseng stems after frost, while increased in ginseng leaves. The content of phenolic compounds in ginseng stems and leaves were both decreased after frost while the ability of DPPH radical scavenging was improved. The factor of frost has great impact on the quality of ginseng stems and leaves.

We study the behavior of U.S. markets both before and after U.S. Federal Open Market Commission meetings and show that the announcement of a U.S. Federal Reserve rate change causes a financial shock, where the dynamics after the announcement is described by an analog of the Omori earthquake law. We quantify the rate n(t) of aftershocks following an interest-rate change at time T and find power-law decay which scales as n(t-T)∼(t-T) -Ω , with Ω positive. Surprisingly, we find that the same law describes the rate n ' (|t-T|) of 'preshocks' before the interest-rate change at time T. This study quantitatively relates the size of the market response to the news which caused the shock and uncovers the presence of quantifiable preshocks. We demonstrate that the news associated with interest-rate change is responsible for causing both the anticipation before the announcement and the surprise after the announcement. We estimate the magnitude of financial news using the relative difference between the U.S. Treasury Bill and the Federal Funds effective rate. Our results are consistent with the 'sign effect', in which 'bad news' has a larger impact than 'good news'. Furthermore, we observe significant volatility aftershocks, confirming a 'market under-reaction' that lasts at least one trading day.

One of the objectives of the health transformation plan (HTP) in Iran is to reduce out-of-pocket (OOP) payments for inpatient services and eradicate informal payments. The HTP has three phases: the first phase (launched in May 5, 2014) is focused on reducing OOP payments for inpatient services; the second phase (launched in May 22, 2014) is focused on primary healthcare (PHC) and the third phase utilizes an updated relative value units for health services (launched in September 29, 2014) and is focused on the elimination of informal payments. This aim of this study was to determine the OOP payments and the frequency of informal cash payments to physicians for inpatient services before and after the HTP in Kurdistan province, Iran. This quasi-experimental study used multistage sampling method to select and evaluate 265 patients discharged from hospitals in Kurdistan province. The study covered 3 phases (before the HTP, after the first, and third phases of the HTP). Part of the data was collected using a hospital information system form and the rest were collected using a questionnaire. Data were analyzed using Fisher exact test, logistic regression, and independent samples t test. The mean OOP payments before the HTP and after the first and third phases, respectively, were US$59.4, US$17.6, and US$14.3 in hospital affiliated to the Ministry of Health and Medical Education (MoHME), US$39.6, US$33.7, and US$13.7 in hospitals affiliated to Social Security Organization (SSO), and US$153.3, US$188.7, and US$66.4 in private hospitals. In hospitals affiliated to SSO and MoHME there was a significant difference between the mean OOP payments before the HTP and after the third phase (PKurdistan province. © 2017 The Author(s); Published by Kerman University of Medical Sciences.

Full Text Available Menopause women can experience a decrease in saliva secretion (decrease. To understand the clear picture about saliva secretion, the volume, flow rate, pH and viscosity were then measured. The aim of this research was to obtain a picture about the difference of saliva secretion before and after rinsing with baking soda on menopause women. The type of the research used was a laboratory quasi-experiment with comparative descriptive form. The technique used in this research is the survey method, and samples were taken using the multistage cluster random sampling method, and t-student statistical analysis. This research was conducted with the saliva collected with spitting method on 45 menopause women. The results show that the average volume, flow rate, pH and viscosity before rinsing with baking soda was 1.79 ml, 0.18 ml/minute, 7.40 and 0.81 mm2/second. The average volume, flow rate, pH and viscosity after rinsing with baking soda were 2.66 ml; 0.27 ml/minute; 8.67 and 0.78 mm2/second. Statistical analysis t-student on α = 0.05 shows volume changes, flow rate, pH and saliva viscosity before and after rinsing with baking soda was 0.873; 0.086; 1.273 and 0.037 respectively. The conclusion shows a significant difference between saliva secretion before and after rinsing with baking soda, and saliva secretion after rinsing with baking soda on menopause women.

Full Text Available Abstract Objectives It has been suggested that inhibin secretion is altered in women with the polycystic ovary syndrome (PCOS. However, the contribution of a preceding luteal phase has not been taken into account. The aim of the present study was to investigate whether progesterone in the context of a simulated luteal phase affects basal and FSH-induced inhibin secretion in women with PCOS and elevated LH. Methods Ten women with PCOS and 8 normally cycling women participated in an experimental procedure (Exp involving the administration of a single injection of recombinant FSH (450 IU sc. In the women with PCOS, the procedure was performed before (Exp 1 and after a 20-day treatment with progesterone (Exp 2, while in the normal women on day 2 of the cycle (Exp 3. Inhibin A and B levels were measured in blood samples taken before and 24 hours after the FSH injection. Results Basal LH levels were significantly higher and inhibin A levels were significantly lower in the PCOS group compared to the control group, while inhibin B levels were comparable in the two groups. In the PCOS group, after treatment with progesterone inhibin A and LH but not inhibin B levels decreased significantly (p Conclusions In women with PCOS, as compared to control women, the dissimilar pattern of inhibin A and inhibin B secretion in response to FSH appears to be independent of a preceding simulated luteal phase. It is possible that compared to normal ovaries, the PCOS ovaries are less sensitive to endogenous LH regarding inhibin A secretion and more sensitive to exogenous FSH stimulation in terms of inhibin A and inhibin B secretion.

Intensive care admissions during pregnancy, childbirth, and postpartum period are relatively well investigated. However, very little is known about these obstetric patients' health-related quality of life (HRQoL) before and after critical care. The objective of this study was to assess obstetric patients' HRQoL before intensive care admission (baseline) and at 6 months after discharge (follow-up) DESIGN: This was a retrospective database study. In a 5-year period, the data of all women admitted to the intensive care unit (ICU) during pregnancy, delivery, or up to 42 days postpartum were analysed. Four multidisciplinary ICUs of Finnish University hospitals participated. The HRQoL was assessed using the EuroQol-5D (EQ-5D) instrument with utility score (EQsum) and visual analogue scale (EQ-VAS). A total of 283 obstetric patients were identified from the clinical information system. Of these, 99 (35%) completed the EQ-5D questionnaires both at baseline and follow-up, and 65 of them (23%) completed EQ-VAS. The comparison of patients' EQsum scores before intensive care admission and after discharge showed that patients' HRQoL remained good (0.970 vs 0.972) (max 1.0) or increased (0.788 vs 0.982) in 80.8% of the patients. Patients reported improved overall health on the EQ-VAS at 6 months follow-up (EQ-VAS mean, 71.86 vs 88.20; p ≤ 0.001) (max 100). However, 19.2% of the patients had lower HRQoL (EQsum mean 0.987 vs 0.798) at follow-up. Following intensive care, 15% of the patients had more pain/discomfort, and 11% expressed more depression/anxiety. Multiparous patients were more likely to suffer from worsened depression/anxiety (p = 0.024). In the majority of the obstetric patients, HRQoL at 6 months follow-up remained good or had increased from baseline. However, nearly one-fifth of the patients had impaired HRQoL after discharge. Thus, intensive care management should take in to consideration follow-up program after intensive care of ICU-admitted obstetric

Ischemic strokes may accelerate long-term functional decline apart from their acute effects on neurologic function. To test whether the increase in long-term disability is steeper after than before the event for ischemic stroke but not myocardial infarction (MI). In the population-based, prospective cohort Cardiovascular Health Study (1989-2013), longitudinal follow-up was conducted for a mean (SD) of 13 (6.2) years. Follow-up data were used until September 1, 2013; data analysis was performed from August 1, 2013, to June 1, 2016. Models based on generalized estimating equations adjusted for baseline covariates and included a test for different slopes of disability before and after the event. Participants included 5888 Medicare-eligible individuals 65 years or older who were not institutionalized, expected to reside in the area for 3 or more years, and able to provide informed consent. Exclusions were needing a wheelchair, receiving hospice care, and undergoing radiotherapy or chemotherapy. Ischemic stroke and MI. Annual assessments with a disability scale (measuring activities of daily living [ADLs] and instrumental ADLs). The number of ADLs and instrumental ADLs (range, 0-12) that the participant could not perform was analyzed continuously. The mean (SD) age of the entire cohort (n = 5888) was 72.8 (5.6) years; 2495 (42.4%) were male. During follow-up, 382 (6.5%) participants had ischemic stroke and 395 (6.7%) had MI with 1 or more disability assessment after the event. There was a mean of 3.7 (2.4) visits before stroke and 3.7 (2.3) visits after stroke; there was a mean of 3.8 (2.5) visits before MI and 3.8 (2.4) visits after MI. The increase in disability near the time of the event was greater for stroke (0.88 points on the disability scale; 95% CI, 0.57 to 1.20; P < .001) than MI (0.20 points on the disability scale; 95% CI, 0.06 to 0.35; P = .006). The annual increase in disability before stroke (0.06 points per year; 95% CI, 0.002 to 0.12; P�

Objective Many patients use complementary and alternative medicine (CAM) as primary treatment or symptom relief for a variety of illnesses. This study was designed to investigate the influence of surgical removal of a tumor-bearing urogenital organ on CAM use. Methods From 2007 to 2011, 350 patients underwent major urological surgery for kidney, prostate, or bladder cancer at the Goethe-University Hospital, Frankfurt, Germany. Data from 172 patients (49%), who returned a questionnaire, were retrospectively evaluated using the hospital information system along with the questionnaire to objectify CAM use 2 years before and after surgery. Results From the 172 patients returning questionnaires, 56 (33%) used CAM before and/or after surgery and 116 (67%) never used CAM. Of the 56 CAM users, 30 (54%) used CAM presurgery and 53 (95%) used CAM postsurgery, indicating a significant change of mind about CAM use. Patients of German nationality used CAM significantly more than patients of other nationalities. Higher educational status (high-school diploma or higher) was a significant factor in favor of CAM use. The most common type of CAM used before/after surgery was an alternative medical system (63/49%), a manipulative and body-based method (50/19%), and a biological-based therapy (37/32%). Information about CAM, either provided by medical professionals or by other sources, was the main reason determining whether patients used CAM or not. Conclusion The number of patients using CAM almost doubled after surgical removal of a cancer-bearing organ. Better awareness and understanding of CAM use by medical professionals could improve patient counseling. PMID:26491269

The aim of this study was to compare 3.8- and 4.8-mm abutments submitted to simulations of masticatory cycles to examine whether abutment diameter and cemented vs screw-retained crowns affect torque loss of the abutments and crowns. Forty implant/abutment sets were divided into the following groups (n = 10 in each group): (1) G4.8S included 4.8-mm abutment with screw-retained crown; (2) G4.8C included 4.8-mm abutment with cemented crown; (3) G3.8S included 3.8-mm abutment with screw-retained crown; and (4) G3.8C included 3.8-mm abutment with cemented crown. All abutments were tightened with torque values of 20 Ncm, and 10 Ncm for screw-retained crowns. Torque loss was measured before and after cycling loading (300,000 cycles). Torque loss of screw-retained crowns significantly increased after cycling in abutments of groups G3.8S (P ≤ .05) and G4.8S (P = .001). No difference was noted between the abutments before cycling (P = .735), but G3.8S abutments presented greater torque loss than the other groups after cycling (P = .008). Significant differences were noted in the abutment torque loss before and after cycling loading only for the G3.8C group (P ≤ .05). The abutment diameter affects torque loss of screw-retained crowns and leads to failure during the test; mechanical cycling increases torque loss of abutment screw and screw-retained crowns.

Ethanol (ET) is a substance that modulates the Central Nervous System (CNS). Frequently, ET intake occurs combined with energy drinks, which contain taurine (TA), an important amino acid found in the body (i.e brain and muscles). Although TA administration has been used in the improvement of physical performance, the impact of TA, ET and exercise remains unknown. This study aimed to analyze the acute effect of 6g of Taurine (TA), 0.6 mL∙kg-1 of Ethanol (ET), and Taurine combined with Ethanol (TA+ET) ingestion on the electrocortical activity before and after a moderate intensity exercise in 9 subjects, 5 women (counterbalanced experimental design). In each of the 4 treatments (Placebo—PL, TA, ET and TA+ET), electroencephalography (EEG) tests were conducted in order to analyze changes in absolute beta power (ABP) in the frontal lobe in 3 moments: baseline (before ingestion), peak (before exercise) and post-exercise. In the PL treatment, the frontal areas showed decrease in ABP after exercise. However, in the ET+TA treatment, ABP values were greater after exercise, except for Fp1. The ET treatment had no effect on the Superior Frontal Gyrus area (F3, Fz and F4) and ABP decreased after exercise in Fp1 and Fp2. In the TA treatment, ABP increased after exercise, while it decreased at the peak moment in most of the frontal regions, except for Fp1, F3 and Fz. We concluded that after a moderate intensity exercise, a decrease in cortical activity occurs in placebo treatment. Moreover, we found a inhibitory effect of TA on cortical activity before exercise and a increased in cortical activity after exercise. A small ET dose is not enough to alter ABP in all regions of the frontal cortex and, in combination with TA, it showed an increase in the frontal cortex activity at the post-exercise moment.

The physiological responses to water immersion (WI) are known; however, the responses to stress following WI are poorly characterized. Ten healthy men were exposed to three physiological stressors before and after a 6-h resting WI (32-33°C): 1) a 2-min cold pressor test, 2) a static handgrip test to fatigue at 40% of maximum strength followed by postexercise muscle ischemia in the exercising forearm, and 3) a 15-min 70° head-up-tilt (HUT) test. Heart rate (HR), systolic and diastolic blood pressure (SBP and DBP), cardiac output (Q), limb blood flow (BF), stroke volume (SV), systemic and calf or forearm vascular resistance (SVR and CVR or FVR), baroreflex sensitivity (BRS), and HR variability (HRV) frequency-domain variables [low-frequency (LF), high-frequency (HF), and normalized (n)] were measured. Cold pressor test showed lower HR, SBP, SV, Q, calf BF, LFnHRV, and LF/HFHRV and higher CVR and HFnHRV after than before WI (P lower HR, SBP, SV, Q, and calf BF and higher SVR and CVR after than before WI (P lower after than before WI (P lower SBP, DBP, SV, forearm BF, and BRS and higher HR, FVR, LF/HFHRV, and LFnHRV after than before WI (P < 0.05). The changes suggest differential activation/depression during cold pressor and handgrip (reduced sympathetic/elevated parasympathetic) and HUT (elevated sympathetic/reduced parasympathetic) following 6 h of WI.

BACKGROUND: As little is known about the ability to work in patients with infectious spondylodiscitis, we compared the relation between the workforce before infection with that of a reference population and described the patients' ability to work after infection including predictors of return...... to work (RTW). METHODS: We identified all patients aged 20-57 years treated for infectious spondylodiscitis January 1994-May 2009 at hospitals in Funen County, Denmark. The work status of each week from 2 years before until 2 years after index date was compared with that of a reference population. Time...... before infection compared with a reference population and infection further lowered their ability to RTW....

To evaluate preretinal partial pressure of oxygen (PO2) gradients before and after experimental pars plana vitrectomy. Arteriolar, venous, and intervascular preretinal PO2 gradients were recorded in 7 minipigs during slow withdrawal of oxygen-sensitive microelectrodes (10-μm tip diameter) from the vitreoretinal interface to 2 mm into the vitreous cavity. Recordings were repeated after pars plana vitrectomy and balanced salt solution (BSS) intraocular perfusion. Arteriolar, venous, and intervascular preretinal PO2 at the vitreoretinal interface were 62.3 ± 13.8, 22.5 ± 3.3, and 17.0 ± 7.5 mmHg, respectively, before vitrectomy; 97.7 ± 19.9, 40.0 ± 21.9, and 56.3 ± 28.4 mmHg, respectively, immediately after vitrectomy; and 59.0 ± 27.4, 25.2 ± 3.0, and 21.5 ± 4.5 mmHg, respectively, 2½ hours after interruption of BSS perfusion. PO2 2 mm from the vitreoretinal interface was 28.4 ± 3.6 mmHg before vitrectomy; 151.8 ± 4.5 mmHg immediately after vitrectomy; and 34.8 ± 4.1 mmHg 2½ hours after interruption of BSS perfusion. PO2 gradients were still present after vitrectomy, with the same patterns as before vitrectomy. Preretinal PO2 gradients are not eliminated after pars plana vitrectomy. During BSS perfusion, vitreous cavity PO2 is very high. Interruption of BSS perfusion evokes progressive equilibration of vitreous cavity PO2 with concomitant progressive return of preretinal PO2 gradients to their previtrectomy patterns. This indicates that preretinal diffusion of oxygen is not altered after vitrectomy. The beneficial effect of vitrectomy in ischemic retinal diseases or macular edema may be related to other mechanisms, such as increased oxygen convection currents or removal of growth factors and cytokines secreted in the vitreous.

The aim of this study was to determine employment outcomes after radiotherapy (RT) for prostate cancer (PCa). The Danish DREAM database contains information about social benefits paid to Danish citizens. Data are recorded prospectively every week. From the database, it is possible to assess whether a patient is working, on sick leave or retired at a certain time. Data on 417 Danish citizens treated with RT for PCa at Rigshospitalet, Copenhagen, between 1 January 2005 and 1 May 2010 were obtained from the database. The data were collected during a 2 year period from 1 year before RT to 1 year after RT. Among patients of working age, 75% were still available for work 1 year after RT. The degree of sick leave increased almost continuously in the year before the start of RT and reached a maximum of 56% during RT. After RT it gradually declined. There was no significant difference between the number of patients on sick leave 1 year after RT compared to 1 year before RT (p = 0.23). Patients spent a significantly higher number of weeks on sick leave in the year after the start of RT compared to the year before RT (p = 0.001). Except for a transient increase in sick leave during treatment, RT did not seem to affect the working lives of patients with PCa significantly.

This study was undertaken to evaluate /sup 99m/Tc-DTPA renography before and after extracorporeal shock wave lithotripsy (ESWL). Twelve patients with renal calculi were examined in this study. In three patients, bilateral kidneys were treated with ESWL. Sequential renal images of the vascular phase, and the functional and excretory phases were taken using a gamma camera (ZLC 7500, Siemens), after intravenous injection of 555 MBq of /sup 99m/Tc-DTPA. Renograms were generated using data stored every 10 seconds for a period of 30 minutes by computer (Scintipac-2400, Shimadzu). Some treated kidneys were enlarged and/or showed uniform retention of radioactivity on sequential images, within a week after ESWL. Renogram patterns after ESWL were varied in each patient. The renogram findings after ESWL seemed to be affected by the presence or absence of stone fragments in the urinary tract.

Objective: To analyze the characteristics of breast cancer blood supply before and after chemotherapy with low-dose CT perfusion. Methods: Fifteen patients with breast cancer underwent CT breast perfusion examination, which was performed before and after chemotherapy within 1 week on Siemens Sensation 4 scanner with 120 kV and 50 mAs, 50 ml of nonionic contrast agent (320 mg I/ml) was injected at a flow rate of 4 ml/s with a power injector, Scan started after 8 seconds delay and data acquisition duration was 50 seconds. The blood flow (BF), blood volume (BV) and mean transfer time (MTT) of lesion and contralateral normal breast gland were calculated using Basama perfusion 3 software package before and after chemotherapy. At the same time, the tumor size before and after chemotherapy were measured and correlated with the BF values. The t test and non-parametric test were used for the statistics. Results: (1) The mean BF, BV and MTT of breast cancer were (33.20±4.17) ml·min -1 ·100 ml -1 , (8.31±2.43) ml· 100 ml -1 and (15.31±4.31) s respectively before chemotherapy, and (13.65±6.04) ml·min -1 · 100 ml -1 (5.04±2.33) ml·100 ml -1 and (25.97±9.07) s respectively after chemotherapy and there were statistically significant (P=0.000). The mean BF, BV and MTT of normal breast were (4.31±2.23) ml -1 , min -1 ·100 ml -1 , (1.38±0.75) ml·100 ml -1 and ( 19.25±3.94) s respectively before chemotherapy, and (4.03±2.35) ml·min -1 ·100 ml -1 , (1.44±0.84) ml·100 ml -1 , (22.56±7.71 ) s respectively after chemotherapy and there were not statistically significant (P>0.05). (2)The BF of breast cancer was higher than the normal breast before chemotherapy (P<0.01). (3)There was a positive correlation between the BF values and tumor size before and after chemotherapy (r=0.902, P=0.000). Conclusion: The BF value has a positive correlation with tumor size after chemotherapy, CT perfusion is more sensitive for the evaluation of chemotherapy response than morphologic

global population projections forecast large growth in demand for long-term care (LTC) and acute hospital services for older people. Few studies report changes in hospitalisation rates before and after entry into LTC. This study compares hospitalisation rates 1 year before and after LTC entry. the Older Persons' Ability Level (OPAL) study was a 2008 census-type survey of LTC facilities in Auckland, New Zealand. OPAL resident hospital admissions and deaths were obtained from routinely collected national databases. all 2,244 residents (66% = female) who entered LTC within 12 months prior to OPAL were included. There were 3,363 hospitalisations, 2,424 in 12 months before and 939 in 12 months after entry, and 364 deaths. In the 6 to 12 months before LTC entry, the hospitalisation rate/100 person-years was 67.3 (95% confidence interval [CI] 62.5-72.1). Weekly rates then rose steeply to over 450/100 person-years in the 6 months immediately before LTC entry. In the 6 months after LTC entry, the rate fell to 49.1 (CI 44.9-53.3; RR 0.73 (CI 0.65-0.82, P < 0.0001)) and decreased further 6 to 12 months after entry to 41.1 (CI 37.1-45.1; rate ratio [RR] 0.61 (CI 0.54-0.69, P < 0.0001)). increased hospitalisations a few months before LTC entry suggest functional and medical instability precipitates LTC entry. New residents utilise hospital beds less frequently than when at home before that unstable period. Further research is needed to determine effective interventions to avoid some hospitalisations and possibly also LTC entry. © The Author 2016.

Potassium antimonite precipitation was used to locate calcium in the central cell of lettuce (Lactuca sativa L.) before and after pollination. At 3d before anthesis, two polar nuclei of central cell separately located at two polarity of the cell, and few calcium precipitates (ppts) appeared in the polar nuclei and cytoplasm, but some ppts in its small vacuoles. At 2d before anthesis, two polar nuclei moved toward the middle of the cell and fused to form a secondary nucleus, and the ppts evidently increased in the nucleus and cytoplasm. At 1d before anthesis, secondary nucleus again moved toward micropylar end and located near the egg to prepare for fertilization. Calcium precipitates were mainly accumulated in the secondary nucleus. After pollination and before fertilization, the distribution of calcium ppts was similar to that before pollination. At 4h after pollination, the central cell was fertilized, and calcium ppts evidently increased in the cell and numerous were accumulated in its nucleus and cytoplasm. At 6h after pollination, the primary endosperm nucleus completed its first division and formed two dissociate endosperm nuclei, and still many calcium precipitates appeared in the nucleus and cytoplasm. With endosperm development, calcium ppts decreased in the endosperm cell. At 1d after emasculated and without pollination, the secondary nucleus of the cell still bordered on the egg and some calcium ppts appeared in the secondary nucleus. The results indicated that the temporal and spatial changes of calcium in the central cell may play an important physiological role during the development of the central cell and endosperm.

Full Text Available Objective. Lifestyle modification programs are different but typically include both nutritional aspects and physical activity as main domains with different behavioral and/or psychological strategies designed to affect change. A fundamental role in modifying unhealthy habits is played by personal motivation for change. The present study sought to investigate, in a group of 100 overweight/obese outpatients with and/or without TMD2, treatment seeking, the effect of an intensive lifestyle program on medical measures and motivational profile for physical activity (PA and healthy nutrition (NUTR. Method. Subjects participated in an intensive multidisciplinary lifestyle intervention at C.U.R.I.A.MO. Before and after the intervention, patients received a comprehensive evaluation of their clinical, anthropometric, and metabolic states and motivation to lifestyle changes. Results. Data showed differences before and after intervention in both medical and motivational measures. Before the intervention patients reported to be ready, open, and determined to change and gave importance to healthy habits. After the intervention patients continued to be determined but increased the actions toward the change showing a higher degree of maintenance and of acquisition of habits especially in the physical domain of the new lifestyle. Conclusion. Data support the notion that the motivation should be followed during all the lifestyle interventions to support the change on both domains of the lifestyle program.

Objective: To evaluate the clinical utility and accuracy of dynamic MR digital subtraction angiography (MR-DSA) in the detection of intracranial arteriovenous malformations before and after embolization. Methods: A prospective blinded comparison of MR-DSA, 3D contrast-enhanced T 1 -weighted MR angiography (3D-CEMRA), proton-weighted imaging and conventional digital subtraction angiography (DSA) were underwent in 22 consecutive AVMs patients before and after embolization. Two readers independently interpreted images and compared with DSA images. Results: There was complete agreement between MR-DSA and DSA for classification and size of nidus before and after embolization in all cases. MR-DSA showed the modified hemodynamic features (the time of nidus, early venous enhancement delayed after carotid arteries appearance) in 17 cases, and nidus size were reduced in 13 cases (including 4 complete embolized cases) after embolization, which were 100% consistence compared with DSA. MR-DSA failed to depict 1 intranidal aneurysm and missed 1 less dilated artery and draining vein after embolization respectively, which were demonstrated clearly by 3D-CEMRA confirmed with DSA. The relatively more or less hyperintensity could be seen on proton-weighted imaging in all cases after embolization than before. Conclusion: MR-DSA is a fast, efficient, and noninvasive technique to provide hemodynamic information relevant for AVMs before and after embolization. Proton imaging is sensitive in delineation of the embolized region, MR-DSA, 3D-CEMRA and proton-weighted imaging should be combined in the evaluation and follow-up AVMs after partial embolization.

International Nuclear Information System (INIS)

Oppermann, H.C.; Mehls, O.; Willich, E.; Twittenhof, W.D.

1981-01-01

From 1969 to 1980 202 children suffering from chronic renal insufficiency underwent treatment in the Children's Hospital of Heidelberg University. In 36 patients kidney transplantations were performed. Two children developed femoral head necroses before transplantation without corticosteroid therapy. Three patients developed femoral head necroses in one or both sides within one to 24 months after kidney transplantation. All children with femoral head necrosis were suffering from congenital renal disease and had a history of servere renal osteodystrophy which was followed by severe coxa vara. Coxa vara and the resulting faulty loading seem to be essential factors for the development of femoral head necrosis in patients with renal insufficiency before and after kidney transplantation.

Objective. To evaluate the findings in MRI-studies of the knee in recreational long-distance runners after competition and to assess the reversibility of the findings.Design and patients. Eight recreational long-distance runners underwent MRI studies of the knee before, immediately after and 6-8 weeks after taking part in the Vienna City Marathon. The studies were evaluated regarding alterations of pre-existing lesions and new pathological findings.Results. In six runners without major pre-existing alterations no negative effects were experienced. In one runner with pre-existing grade III alterations of the menisci, signs of progressive osteoarthritis were experienced 2 months after the competition. In all other cases increased meniscal signal alterations and minor signal changes in the bone marrow after the race were transitory.Conclusion. In healthy individuals no negative long-term-effects were experienced. Pre-existing high-grade lesions of the menisci might be a predisposing risk for osteoarthritis, triggered by the stress of long-distance running. (orig.)

D D Baksi

2011-01-01

Full Text Available Background: Patellar dislocations are either due to superolateral contracture of the soft tissue or imbalance of the power between the vastus medialis (VM and the vastus lateralis (VL. The imbalance of muscle power as an etiology of patellar dislocation has not been studied. Hence, we studied the recurrent, habitual and permanent dislocations of the patella with an electromyogram (EMG of the vastus medialis, vastus lateralis, and pes anserinus, before and after realignment operations, to document the muscle imbalance and effectiveness of the realignment operation. Materials and Methods: An electromyographic investigation was carried out on the vastus medialis and vastus lateralis in nine recurrent, 20 habitual, and 13 permanent dislocations of the patella, before and after their realignment operations. Pes anserinus transposition, which acted as a medial stabilizer of the patella, was also investigated with an EMG study, to understand its role on patellar stability at 0΀, 30΀, 60΀, 90΀, 120΀, 150΀, and full flexion of the knee. The age of the patients varied from nine to 30 (mean 15 years. There were 24 males and 18 females. Twenty-six patellar dislocations were on the right and 16 were on the left side. Results: Electromyographic pictures reveal subnormal activity of the vastus medialis in all types of dislocations and similar activities of the vastus lateralis in permanent and habitual dislocations recorded pre operatively, which recovered to almost normal values postoperatively, at the mean one-year follow-up. Pes anserinus, which was used for medial stabilization of the patella after its realignment, maintained normal EMG activity before and after the operation. Conclusion: This study is significant for understanding the imbalance of muscle activities in patients with an unstable patella, which can be rectified without recurrence after pes anserinus transposition.

Full Text Available Background. Data is limited on the burden of common comorbidities, such as cardiovascular disease (CVD, respiratory disease and diabetes, or comorbidities related to cancer and its treatment, such as anemia and depression, in patients with soft tissue sarcoma (STS. Patients and Methods. From the Dutch Pathology Registry linked to the PHARMO database (including data on drug use and hospitalizations, 533 patients with STS were selected during 2000–2007 and matched 1 : 10 to cancer-free controls. The occurrences of comorbidities were assessed in the 12 months before and after STS diagnosis. Results. STS patients were 2–4 times more likely to have comorbidities at diagnosis compared with cancer-free controls. The incidence of CVD, anemia, and depression after STS diagnosis differed significantly from cancer-free controls and decreased during followup from 40–124 per 1,000 person-years (py during the first six months to 11–38 per 1,000 py more than 12 months after diagnosis. The incidence of respiratory disease and diabetes among STS patients remained stable during followup (5–21 per 1,000 py and did not differ significantly from cancer-free controls. Conclusions. STS patients were more likely to have comorbidities before cancer diagnosis and to develop CVD, anemia, and depression after diagnosis compared to cancer-free controls.

Full Text Available This study focuses on one aspect of a more extensive SANPAD-funded HIV stigma reduction research project. The study addresses not only the continuous burden of HIV stigma, but more specifically on the low rate of participation in healthcare opportunities and HIV stigma reduction interventions by people living with HIV (PLWH This study tested both change-over-time in HIV stigma experiences of PLWH and change-over-time in the HIV stigmatisation behaviour of people living close to them (PLC in an urban and rural setting in the North-West in South Africa. These aspects were measured before and after the comprehensive community-based HIV stigma reduction intervention. A quantitative single system research design, with a pre-test and four repetitive post-tests, and purposive voluntary and snowball sampling were used. Findings did not indicate significant differences between urban and rural settings, but demonstrated some significance in change-over-time in the HIV stigma experiences of PLWH as well as the HIV stigmatisationbehaviour of PLC after the intervention. Recommendations include the continuation of this intervention, following the same guidelines that were implemented during the study.

Objective: Assessing the value of 99 Tc m -MIBI myocardial perfusion imaging (SPECT) in selection of patients for stenting, and in evaluation of the therapeutic effects of the procedure and its value for following-up of the patients with coronary artery stents. Methods: Rest and dipyridamole stress SPECT were performed in 51 patients with coronary artery diseases and coronary artery stents one week before procedure, one week and half a year (21 cases) after procedure. The location, degree and area of blood flow deficit were quantitatively analyzed. Results: Before the procedure, 50 patients showed blood flow deficit degree >80% (the lower the percentage, the more the blood flow deficit degree), blood flow deficit area 80%, 8 (16%) patients who had been with blood flow deficit area 70% before the procedure, 10 (20%) of them one week after procedure were without any severe blood flow deficit. Their acute myocardial infarctions were significantly improved. Pre-procedure, at rest, the blood flow deficit degree was 38.05%, at one week after procedure became 57.40%, it was improved by 19.35%. The patients with blood flow deficit area of 70.75% at rest before the procedure, showed a deficit area of 55.91% one week after the procedure. Compared to pre-procedure readings, the significant improvement (P 0.05) in blood flow deficit degree and area between rest and dipyridamole stress SPECT before or one week, half a year after procedure. Conclusions: The blood flow deficit degree or area measured by SPECT were improved one week and half a year after procedure. SPECT is valuable in selection of patients for the procedure and in evaluation of the effect of the therapy and it is very useful during follow-up of the patients with intracoronary stents

Full Text Available Background and purpose: The importance of training basic and advanced life support for undergraduates and graduated physicians are now widely recognized. Graduates of medical schools in Iran immediately get license to practice medicine without any supervision. Therefore,Clarification of the best phases for training CPR and the optimum mastery level in each phase is very important. This study is an attempt to find out the ideas of stakeholders about training CPR beforeinternship, the experience needed at the beginning of internship, the best phase for training it and the assessment method.Methods: It is a survey study designed in Isfahan University of Medical Sciences to investigate the opinions of head-nurses, interns, residents and educational directors (in ten clinical departments/wards about training CPR before internship. Respondents completed self administered anonymous questionnaires. The questionnaires’ items covered opinions of respondents about CPR as interns’ duty, level of experience; best course for training and the assessment method. Meanwhile, views of participants were compared against educational directors’ idea by Fisher exact test.Results:32 head-nurse, 285 interns, 13 resident and15 educational directors participated in the study and all agreed with CPR as interns’ duty in all clinical wards. Although, directors had different idea about level of experience for CPR to be achieved by interns, residents suggested level 3 of experience. According to the results externship is the best phase for CPR training and combination of observation and OSCE suggested as the best assessment method.Conclusion: To prepare the graduates achieving full competency in CPR performance, it is needed to implement training programs before internship. Internship is the best phase for getting expertise in CPR. Based on the results CPR considered as interns’ responsibility and medical schools should feel confidence about the competency ofinterns

A bacteriological study of hospital beds before and after disinfection with phenolic disinfectant

Andrade Denise de

2000-01-01

Full Text Available In hospitals, one of the ways to control microbial contamination is by disinfecting the furniture used by patients. This study's main objective was to evaluate the microbiological condition of hospital mattresses before and after such disinfection, in order to identify bacteria that are epidemiologically important in nosocomial infection, such as Staphylococcus aureus and Pseudomonas aeruginosa. RODAC plates with two different culture media were used to collect specimens. Patient beds were selected according to previously established criteria, and surface areas on the mattresses were chosen at random. From the total of 1 040 plate cultures from 52 mattresses, positive results were obtained from 500 of them (48.1%, 263 before disinfection and 237 after disinfection. Considering the selectivity of the culture media, the positivity rate was high. There were high prevalences of S. aureus both before and after mattress disinfection. The study results suggest that the usual disinfection procedures, instead of diminishing the number of microbes, merely displace them from one part of the mattress to another, and the number of microorganisms remains the same.

2005-04-01

Full Text Available Introduction: Leptin is a fat tissue hormone that has 176 amino acids with a molecular weight of 16 KD . Leptin has effects on the hypothalamus and peripheral tissues resulting in decreased food absorption and increased energy consumption that finally reduces the body weight and BMI. The aim of this research was to investigate the blood levels of leptin before and after treatment with Metformin in type II diabetic patients. Methods: 25 type II diabetic patients without any previous drug treatment history were investigated. This study was a clinical trail before and after treatment with Metformin. Results: There was no particular difference in BMI, average body weight, fat mass and free fat mass before and after treatment. Similarly, the difference in concentration levels of blood glucose, cholesterol, tri-glycerides and LDL-cholesterol before and after treatment was not statistically significant. Also, there was no difference in the average concentration of leptin and insulin before and after treatment Conclusion: This result showed that although metformin decreased glucose and lipid levels during the treatment period, (1 month it did not have an effect on leptin, Insulin and other related factors during treatment.;

Full Text Available This paper investigates the linkages among equity markets of four European countries (Germany, France, Italy, UK and the USA in terms of market returns and transmission of volatilities. We use daily exchange traded funds (ETF data from January 2002 to March 2016 and utilize both a Multivariate Autoregressive Moving Average model (MARMA and a Generalized Autoregressive Conditional Heteroskedasticity model (GARCH. We divided the data into three separate periods: before the 2007-08 financial crisis, during the crisis and after the crisis. The results show the existence of significant co-movement of returns in all three selected periods although some important differences before and after the financial crisis are noted. Findings also include marked increases in integration of the markets and thus diminishing diversification opportunities for investors. Volatilities appear to react strongly to market movements and their shocks fade away slowly in all five countries during the crisis period. There is also strong evidence of volatility spillovers particularly during and after the crisis periods.

Full Text Available PURPOSE: To evaluate alanine aminotransferase levels before and after a hemodialysis session and to correlate these values with the hematocrit rate and weight loss during hemodialysis. PATIENTS AND METHODS: The serum alanine aminotransferase levels, hematocrit rate and body weight were measured and correlated before and after a single hemodialysis session for 146 patients with chronic renal failure. An receiver operating characteristic (ROC curve for the serum alanine aminotransferase levels collected before and after hemodialysis was plotted to identify hepatitis C virus-infected patients. RESULTS: The mean weight loss of the 146 patients during hemodialysis was 5.3% (p < 0.001. The mean alanine aminotransferase levels before and after hemodialysis were 18.8 and 23.9 IU/, respectively, denoting a significant 28.1% increase. An equally significant increase of 16.4% in the hematocrit rate also occurred after hemodialysis. The weight loss was inversely correlated with the rise in both the alanine aminotransferase level (r = 0.3; p < 0.001 and hematocrit rate (r = 0.5; p < 0.001. A direct correlation was found between the rise in alanine aminotransferase levels and the hematocrit during the hemodialysis session (r = 0.4; p < 0.001. Based on the ROC curve, the upper limit of the normal alanine aminotransferase level should be reduced by 40% relative to the upper limit of normal if the blood samples are collected before the hemodialysis session or by 60% if blood samples are collected after the session. CONCLUSION: In the present study, significant elevations in the serum alanine aminotransferase levels and hematocrit rates occurred in parallel to a reduction in body weight after the hemodialysis session. These findings suggest that one of the factors for low alanine aminotransferase levels prior to hemodialysis could be hemodilution in patients with chronic renal failure.

Full Text Available AIM: To make a contrast and then analyze the difference of optical coherence tomography(OCTbefore and after vitreomacular traction syndrome(VTSwas performed. METHODS: The clinical date of 11 evaluable eyes of 11 patients with VTS who were diagnosed by OCT and underwent 25G vitreous surgery from January 2013 to January 2014 were retrospectively analyzed. Patients were followed up for an average of 6mo, to observe the visual acuity and OCT examination of the patient before and after operation. We compared the changes of retinal thickness and local morphology before and after operation.RESULTS: After vitreous retraction, 6 eyes improved, 2 eyes do not improve. One eye received macular membrane traction, in the operation the macular epiretinal membrane peeling, retrial membrane stripping and the triamcinolone acetonide intravitreal injection were given, but after the operation, the vision does not improve. Two eyes received vitreous combined with retinal macular membrane traction. In the operation, macular epiretinal membrane stripping was given, after the operation, visual acuity improved. The proportion of those with visual acuity of 0.1 or more increased from 46% before to 73% after the operation. Before operations, the mean central macular thickness was 619.27±195.13μm, 239.12±143.84μm after, which decreased significantly(PCONCLUSION: Vitrectomy can effectively relieve the vitreous traction of the macula, and can prevent further decline in visual acuity and reduce macular edema as well as improve the visual acuity of some patients. So, OCT has important guiding significance on the diagnosis and prognosis of this group.

To determine the point prevalence of painful musculoskeletal (MSK) conditions in obese subjects before and after weight loss following bariatric surgery. Longitudinal, interventional, unblended. Forty-eight obese subjects (47 women, one man, mean age 44+/-9 years; mean body mass index (BMI) 51+/-8 kg/m(2)) recruited from an academic medical center bariatric surgery program. Comorbid medical conditions; MSK findings; BMI; Western Ontario McMaster Osteoarthritis Index (WOMAC) for pain, stiffness and function; and SF-36 for quality of life. Consecutive subjects were recruited from the University Hospitals of Cleveland Bariatric Surgery Program. Musculoskeletal signs and symptoms and non-MSK comorbid conditions were documented at baseline and at follow-up. SUBJECTS completed the SF-36 and the WOMAC questionnaires. Analyses were carried out for each MSK site, fibromyalgia syndrome (FMS) and for the cumulative effect on the spine, upper and lower extremities. The impact of change in comorbid medical conditions, BMI, physical and mental health domains of the SF-36 on the WOMAC pain subscale score was evaluated. SF-36 outcomes were compared to normal published controls. Forty-eight subjects were available for baseline and a follow-up assessment 6-12 months after gastric bypass surgery. They lost an average of 41+/-15 kg and the mean BMI decreased from 51+/-8 to 36+/-7 kg/m(2). Baseline comorbid medical conditions were present in 96% before surgery and 23% after weight loss. There was an increased prevalence of painful MSK conditions at baseline compared to general population frequencies. Musculoskeletal complaints had been present in 100% of obese subjects before, and 23% after weight loss. The greatest improvements occurred in the cervical and lumbar spine, the foot and in FMS (decreased by 90, 83, 83 and 92%, respectively). Seventy-nine percent had upper extremity MSK conditions before and 40% after weight loss. Before surgery, 100% had lower extremity MSK conditions and

Background Blood eosinophil and basophil levels have recently been considered for the purpose of endotyping chronic rhinosinusitis with nasal polyps (CRSwNP). Histologically, eosinophilic-type CRSwNPs have been associated with high recurrence rates after treatment. Objective The present study was the first to compare blood eosinophil and basophil counts in eosinophilic-type CRSwNP patients before and after endoscopic sinus surgery. Methods The study concerned 79 consecutive patients with histologically confirmed eosinophilic-type CRSwNP treated with endoscopic sinus surgery. Results A significant drop in mean blood eosinophil counts and percentages occurred from before to after endoscopic sinus surgery in the cohort as a whole. Mean blood eosinophil counts and percentages were also reduced after surgery in the subcohorts of CRSwNP patients with (i) asthma, (ii) aspirin-exacerbated respiratory disease (AERD), and (iii) no allergy. Although blood eosinophil and basophil counts correlated directly before and after surgery, a statistical reduction in blood basophil counts and percentages after surgery emerged only in the subcohort of nonallergic CRSwNP patients. Conclusion Endoscopic sinus surgery can clear polyps, remove inflammatory tissue, and reduce inflammatory cytokine levels. Consistently with the biological mechanism described, endoscopic sinus surgery could coincide with a reduction in blood eosinophils in eosinophilic-type CRSwNP.

To evaluate the survival and growth potential of human preantral follicles isolated before and after cryopreservation. Pilot study. Gynecology research unit in a university hospital. Six women aged 27 to 32 years. Six ovarian biopsy samples were cut into two equal parts, half subjected to slow-freezing followed by follicle isolation (cryo-iso group) and alginate-matrigel embedding, and half immediately processed for follicle isolation and alginate-matrigel embedding followed by slow-freezing (iso-cryo group) or used as fresh controls (fresh group). Follicle number, viability, diameter, and morphology. After 1,134 preantral follicles had been isolated from fresh biopsy samples and 1,132 from frozen specimens, the three groups were compared before and after 7 days of in vitro culture (IVC) in alginate-matrigel beads. No statistically significant differences in viability were found between the three groups before or after IVC, but follicle diameter increased in all three groups after IVC. Morphology analysis revealed well-preserved follicles in both the iso-cryo and cryo-iso groups after IVC. Human preantral follicles can be successfully cryopreserved before or after isolation without impairing their ability to survive and grow in vitro. This could lead to development of new protocols for follicle cryopreservation, IVC, and grafting in clinical and research settings for fertility preservation.

To investigate changes in the ovary revealed by MR imaging before and after radiotherapy in premenopausal patients with cervical carcinoma. Thirty-three premenopausal patients with cervical carcinoma underwent radiation therapy at an average dosage of 11,279 (external: 5,352; internal: 5,927) cGy. Before and after this therapy, all underwent pelvic MR imaging using a 1.5T MR scanner (GE Medical Systems, Milwaukee, U.S.A.). The average interval of follow-up MR imaging was 7.2 months, and axial T1-weighted and axial and sagittal T2-weighted MR images were obtained. The presence, size number of follicles, and differentiation of the zonal anatomy of the ovary were determined by two radiologists, who reached a consensus. After radiation therapy, all patients ceased menstruation. For ovaries, the detection rates before and after radiation therapy were 94% (62/66) and 39% (26/66) ({rho}<0.05), respectively, and average ovary size was 2.6 X 1.9 X 2.2 cm before and 1.7 X 1.3 X 1.4 cm after therapy ({rho}<0.05). The average number of ovarian follicles before and after therapy was 5.1 and 3.1, respectively ({rho}<0.05). T2-weighted imaging, demonstrated differentiation of zonal anatomy in 74% of cases (46/62) before radiotheraphy, and 15% (4/26) after ({rho}<0.05). Our study has shown that after radiation therapy in premenopausal patients with cervical cancer, detection rates, average size, and the number of ovaries decreased, findings which are similar to those for normal postmenopausal ovary. MR imaging can reveal structural change in ovaries.

The present studies concern the basic ventilatory indices, the arterial blood gases, the indices of the acid-base balance and the indices of the alveolar-capillary diffusion (DLCO, SS, Dm, theta Vc) in anemia before and after treatment. Substantial changes are recorded after treatment mainly in DLCO, SS and theta Vc. These changes are predominantly due to changes in the concentration of Hb. An evaluation of both methods for the standardization of DLCO at 14,6 g Hb/100 ml blood is also presented.

Definitive chemoradiotherapy is often considered for locally advanced esophageal cancer. We studied the effect of chemoradiotherapy treatment on patients' quality of life and late toxicities. Patients undergoing definitive 5-fluorouracil and cis-diammine-glycolatoplatinum (nedaplatin) therapy concurrent with radiotherapy for esophageal cancer without operation adaptation completed standardized quality-of-life questionnaires before and after chemoradiotherapy and at regular times up to -5 years. We analyzed differences in a generic quality-of-life score questionnaire (Functional Assessment of Cancer Therapy-Esophageal scoring) over time by using a linear mixed-effects model. Longitudinal changes before the start of treatment were able to be evaluated in a total of 80 patients. The quality-of-life score before treatment was worse in patients with advanced stages than those with early stages. The quality-of-life score deteriorated once at the time of 2 or 3 months after starting chemoradiotherapy compared with pre-chemoradiotherapy and recovered and rose higher at 4 or 5 months than before starting chemoradiotherapy. After that, the recovery of quality of life was maintained up to the observation end. The score of physical functioning such as fatigue, nausea/vomiting, pain and dyspnea deteriorated at the time of 2 or 3 months after starting chemoradiotherapy compared with before chemoradiotherapy (80, 86, 94 and 89%). The quality-of-life score deteriorates once from before treatment due to acute complications by chemoradiotherapy, but recovers at 4 or 5 months and becomes better than before treatment. (author)

Aspirin exacerbated respiratory disease (AERD) is induced by acetylsalicylic acid (ASA) and/or nonsteroidal antiinflammatory drugs (NSAIDs). Effects of desensitization on many mediators have been examined previously, but few studies addressed the influence of desensitization on T lymphocytes and T lymphocyte-derived cytokines. This study was performed to examine peripheral blood lymphocyte (PBL) cytokine expression in aspirin-sensitive patients who have asthma before and after aspirin desensitization. In this study, the release of interleukin-2 (IL-2), interleukin-4 (IL-4), and interferon-gamma (IFN-γ) by CD4+ T lymphocytes prior to aspirin desensitization were also measured at intracellular levels, and expression of these cytokines after 1 month aspirin desensitization was evaluated. Twelve patients with AERD were included in the study. Two different control groups were formed, one consisted of 15 healthy people and second 12 aspirin tolerant asthmatic (ATA) patients using aspirin. A blood sample was collected prior to desensitization, and the tests were repeated by taking a second blood sample 1 month after the 4-day desensitization treatment. The proportion of lymphocytes secreting IFN-γ in the study group was 15.61 ± 4.40 % before desensitization and 15.08 ± 5.89 % after desensitization. The rate of IFN-γ secreting CD4+ T lymphocytes was 20.51 ± 4.41 % in the normal control group and 16.07 ± 5.7 % in the ATA group (p = 0.021). The ratio of CD4+ T lymphocyte secreting IFN-γ was reduced in patients with AERD before desensitization compared to normal control group (p = 0.040). The levels of IL-2, IL-4, and the subsets of lymphocyte were not different before and after desensitization compared to control groups.

Full Text Available This study isolated and quantified intestinal bacteria of children with cleft palate before and after palatoplasty. A prospective study was conducted from May 2007 to September 2008 on 18 children with cleft palate, aged one to four years, of both genders, attending a tertiary cleft center in Brazil for palatoplasty, to analyze the effect of surgical palate repair on the concentration of anaerobes Bacteroides sp, Bifidobacterium sp and microaerophiles Lactobacillus sp in feces of infants with cleft palate before and 24 hours after treatment with cefazolin for palatoplasty. There was significant reduction of Lactobacillus sp (p < 0.002, Bacteroides sp (p < 0.001 and Bifidobacterium sp (p = 0.021 after palatoplasty, revealing that surgery and utilization of cefazolin significantly influenced the fecal microbiota comparing collections before and after surgery. However, due to study limitations, it was not possible to conclude that other isolated factors, such as surgical stress, anesthetics and other medications used in palatoplasty might have a significant influence on the microbiota. Considering the important participation of the intestinal microbiota on both local and systemic metabolic and immunological activities of the host, professionals should be attentive to the possible influence of these changes in patients submitted to cleft repair.

Fujii, Yoshio; Takeda, Toshiharu

Recently it is desirable to realize the conservation of biodiversity and to create the city with symbiosis with nature even in local city. In this study, we chose Nagano City which was the site of the Winter Olympic Games as the subject of study, investigated the change of land cover by using Landsat TM data of the year 1985 and 1999 which were before and after the Winter Olympic Games, and grasped the change of landscape structure quantitatively by using landscape indices. As a result, we obtained the following conclusions. The expansion of urban area proceeded rapidly before and after the Winter Olympic Games. The area of artificial land cover in the city planning area has increased by 57%. In the meantime the areas of upland field and paddy field have decreased by 45% and 50% respectively. Therefore, agricultural land changed into urban area remarkably. It was found that the shape of paches of paddy field and upland field especially became small and the inequality of the paches decreased before and after the Winter Olympic Games. It became clear that the fragmentation has occurred in agricultural land such as paddy field, upland field and orchard.

Antithyroid drug regimens before and after 131I-therapy for hyperthyroidism: evidence-based?

Science.gov (United States)

Mijnhout, G S; Franken, A A M

2008-06-01

In view of the new national guideline on thyroid dysfunction, the evidence base for current practice as well as the new guideline is assessed with regard to the use of antithyroid drugs (ATDs) before and after radioiodine (131I) therapy. In December 2006, we surveyed 16 hospitals by telephone about different aspects of their antithyroid drug regimen: all eight academic centres and eight nonacademic teaching hospitals. The literature was searched for an evidence-based answer to each question in the inquiry. 13 of 16 hospitals (81%) use antithyroid drugs for pretreatment before 131I. ATDs are discontinued on average four days before 131I or diagnostic scan. However, 27% stop only three days beforehand, which may diminish the effect of 131I. Propylthiouracil (PTU) is also withdrawn four days before 131I, although the literature shows that PTU diminishes the effect of 131I even if it is stopped 15 days beforehand. Resumption of ATDs after 131I to prevent thyrotoxicosis is common practice (81%). One hospital (6%) never restarts ATDs, two (13%) only by indication. Adjunctive treatment consists of combination therapy in 93%, is usually resumed within two days after 131I therapy, and then continued for two to six months. Routine adjunctive treatment is not evidence-based and may be limited to a high-risk subset, especially elderly patients (>70 years) and patients with cardiac comorbidity. Resumption of ATDs within five to seven days after 131I may diminish the effect of 131I. Antithyroid drug regimens in the Netherlands are heterogeneous. The evidence base of current practice and the new guideline are discussed.

Udovic, Metka; Lestan, Domen

2007-01-01

The effect of two earthworm species, Lumbricus rubellus and Eisenia fetida, on the fractionation/bioavailability of Pb and Zn before and after soil leaching with EDTA was studied. Four leaching steps with total 12.5 mmol kg -1 EDTA removed 39.8% and 6.1% of Pb and Zn, respectively. EDTA removed Pb from all soil fractions fairly uniformly (assessed using sequential extractions). Zn was mostly present in the chemically inert residual soil fraction, which explains its poor removal. Analysis of earthworm casts and the remainder of the soil indicated that L. rubellus and E. fetida actively regulated soil pH, but did not significantly change Pb and Zn fractionation in non-remediated and remediated soil. However, the bioavailability of Pb (assessed using Ruby's physiologically based extraction test) in E. fetida casts was significantly higher than in the bulk of the soil. In remediated soil the Pb bioavailability in the simulated stomach phase increased by 5.1 times. - Earthworm activity increases heavy metal bioavailability in soil before and after remediation

To measure the expression levels of sputum and serum microRNA-144 (miR-144) before and after the treatment of patients with tuberculosis (TB). Details of the cases of a total of 124 TB patients were collected at Qilu Hospital of Shandong University between April 2014 and April 2015. Fifty-three of these patients had sputum positive for bacteria and a cavity on imaging (group A), 20 patients had sputum negative for bacteria and a cavity on imaging (group B), and 51 patients had sputum negative for bacteria and no cavity on imaging (group C). One hundred seventeen healthy people who attended the hospital for a physical examination were recruited as controls. Quantitative real-time PCR (qRT-PCR) was used to measure the levels of sputum and serum miR-144 before anti-TB treatment and at 1 month after treatment. Before treatment, sputum and serum miR-144 expression levels in the TB patients were both higher than those of the controls (both p<0.05). After treatment, sputum and serum miR-144 levels in the TB patients were significantly lower than those measured before treatment (both p<0.05). The levels of sputum and serum miR-144 in the improved TB patients decreased significantly after treatment compared to those measured before treatment (both p<0.001). Significant differences were found in sputum and serum miR-144 levels in the TB patients, with or without improvement, compared with the healthy controls (all p<0.05). Sputum and serum miR-144 levels were significantly upregulated in the TB patients, but were found to decrease significantly after anti-TB treatment. Copyright © 2016 The Authors.

The present study endeavored to identify predictors of headache during pregnancy, shortly after delivery, and at 8-week follow-up. Many women suffer from headaches during pregnancy and the post-partum period. However, little is known about factors that predict headache surrounding childbirth. Secondary analysis of longitudinal cohort study of 2434 parturients hospitalized for cesarean or vaginal delivery in 4 university hospitals in the United States and Europe. Data were gathered from interviews and review of medical records shortly after delivery; 972 of the women were contacted 8 weeks later to assess persistent headache. The primary outcome measures were experiencing headache during pregnancy, headache within 72 hours after delivery, and headache at 8 weeks after delivery. Of the parturients, 10% experienced headache during pregnancy, 3.7% within 72 hours after delivery, and 3.6% at 8 weeks postdelivery. Compared to those without a history of headache, a history of headache prior to pregnancy was the strongest predictor of headache during pregnancy (9.8% vs 23.5%; risk ratio 2.4; 95% confidence interval [CI]: 1.4 to 4.0). Experiencing headache during pregnancy (adjusted hazard ratio HR 3.8; 95% CI: 2.4 to 6.2) and receiving needle-based regional anesthesia for pain treatment (adjusted hazard ratio 2.2; 95% CI: 1.1 to 4.5) were independently associated with headache within 72 hours after delivery with event rates of 11.1% and 10.5%, respectively. Compared to those without such a history, headache before pregnancy was significantly associated with experiencing headache 8 weeks after delivery (4.0% vs 23.8%; risk ratio = 6.0; 95% CI: 2.0 to 8.0), but headache during pregnancy or shortly after delivery was not. Several other psychosocial predictors (eg, somatization, smoking before pregnancy) were statistically associated with at least 1 headache outcome. A history of headache prior to pregnancy is a strong predictor of headache during and after pregnancy, the

Full Text Available The electronic and optical properties of a-Al2O3 after induced by 3-keV Ar+ sputtering have been studied quantitatively by use of reflection electron energy loss spectroscopy (REELS spectra. The band gap values of a-Al2O3 was determined from the onset values of the energy loss spectrum to the background level of REELS spectra as a function of time Ar+ bombardment. The bandgap changes from 8.4 eV before sputtering to 6.2 eV after 4 minutes of sputtering.The optical properties of α-Al2O3 thin films have been determined by comparing the experimental cross section obtained from reflection electron energy loss spectroscopy with the theoretical inelastic scattering cross section, deduced from the simulated energy loss function (ELF by using QUEELS-ε(k-REELS software. The peak assignments are based on ELF and compared with reported data on the electronic structure of α-Al2O3 obtained using different techniques. The results demonstrate that the electronic and optical properties before and after surface reduction will provide further understanding in the fundamental properties of α-Al2O3 which will be useful in the design, modeling and analysis of devices applications performance.

Full Text Available The aim of the study was to compare the central corneal thickness (CCT, intraocular pressure (IOP, and tear insulin-like growth factor-1 (IGF-1 levels of 2 patients with acromegaly before and after the surgical treatment of the disease. CCTs, IOP levels, and tear IGF-1 values showed a decrease after the treatment in 2 patients. As we found higher CCT, IOP, and tear IGF-1 levels in the active phase of the disease in two acromegaly patients, detailed information about the activity of the disease may be important before the examination of these patients.

The aim of our study was a comparative examination of the congenital anomalies before and directly after the Chernobyl disaster in the early and later periods of time. For the study post mortem material of the Department of general and clinical pathology at the Medical University of Plovdiv was used. Eight hundred seventy eight cases of newborns with congenital anomalies for a 24-year period (1981-2004) were reviewed. The number of the congenital anomalies was compared quantitatively in general and in systems. Equal 5-year intervals of time were compared to a control 5-year period before the Chernobyl accident. The data were statistically processed using different statistical methods. The comparative study of the number of the congenital anomalies did not show a statistically significant increase in relation to the nuclear accident

We present 'Before and After' global oscillation solutions, as well as predicted 'Before and After' values and ranges for ten future solar neutrino observables (for BOREXINO, KamLAND, SNO, and a generic p-p neutrino detector). The 'Before' case includes all solar neutrino data (and some theoretical improvements) available prior to April 20, 2002 and the 'After' case includes, in addition, the new SNO data on the CC, NC, and day-night asymmetry. We have performed global analyses using the full SNO day-night energy spectrum and, alternatively, using just the SNO NC and CC rates and the day-night asymmetry. The LMA solution is the only currently allowed MSW oscillation solution at ∼ 99% CL. The LOW solution is allowed only at more than 2.5σ, SMA is now excluded at 3.7σ or 4.7σ depending upon analysis strategy, and pure sterile oscillations are excluded at more than 4.7σ. Small mixing angles are 'out' (pure sterile is 'way out'); MSW with large mixing angles is definitely 'in'. Vacuum oscillations are allowed at 3σ, but not at 2σ. Precise maximal mixing is excluded at 3.2σ for MSW solutions and at more than 2.8σ for vacuum solutions. Most of the predicted values for future observables for the BOREXINO, KamLAND, and future SNO measurements are changed only by minor amounts by the inclusion of the recent SNO data. In order to test the robustness of the allowed neutrino oscillation regions that are inferred from the measurements and the predicted values for future solar neutrino observables, we have carried out calculations using a variety of strategies for analyzing the SNO and other experimental data.

Full Text Available AIM: The purpose of this study was to compare patients’ sleep problems before and after acute myocardial infarction (AMI and also to determine factors affecting sleep problems in patients undergoing AMI. METHOD: This cross-sectional study was conducted at the Coronary Intensive Care Unit in a training hospital between January 1 and April 30, 2007. The sample of the study was composed of 26 patients with a first-ever AMI. Data were collected by using a questionnaire to determine the patient and illness-related descriptive characteristics and the Post Sleep Inventory Scale (PSIS. The Shapiro-Wilks test, descriptive statistics, paired samples t test, Mann Whitney U test, Wilcoxon test, reliability analysis and correlation analysis were used to analyze the data. RESULTS: The mean age of the study group was 53.2 ± 12.6 years and approximately 81% were males. The patients’ mean bedtime (t= -3.422, p= 0.001, quality of nocturnal sleep (t= -3.221, p= 0.001, awakening (t =-3.533, p<0.001 and total PSIS scores (t= -5.652, p<0.001 were significantly higher after AMI compared to before AMI. The mean PSIS scores of patients undergoing AMI were statistically significant different by gender (z= -2.164, p= 0.030 and working status (z= -2.171, p= 0.030. There was a negative correlation between the PSIS score and haemoglobin and haematocrit values (r= -0.503, p<0.01; r= -0.473, p<0.05; respectively. CONCLUSION: There were differences in the patients’ reported sleep problems between before and after AMI. The results of this study showed that sleep problems were more common among women, patients not working and those with anemia. Nurses should be aware of the sleep problems and factors that affect to sleep problems. [TAF Prev Med Bull 2012; 11(6.000: 687-694

In 2007-2008, a canine distemper virus (CDV) epidemic occurred among wild animals in Wakayama Prefecture, Japan, and many mammals, including the wild boar and deer, were infected. In this study, CDV prevalence among wild animals was surveyed before and after the epidemic. At first, an enzyme-linked immunosorbent assay (ELISA) with horseradish peroxidase-conjugated protein A/G was established to detect CDV antibodies in many mammalian species. This established ELISA was available for testing dogs, raccoons and raccoon dogs as well as virus-neutralization test. Next, a serological survey of wild mammalians was conducted, and it was indicated that many wild mammalians, particularly raccoons, were infected with CDV during the epidemic, but few were infected before and after the epidemic. On the other hand, many raccoon dogs died during the epidemic, but CDV remained prevalent in the remaining population, and a small epidemic occurred in raccoon dogs in 2012-2013. These results indicated that the epidemic of 2007-2008 may have been intensified by transmission to raccoons.

X-, K- and Q-band EPR studies on lyophilized whole pulp parts of blue plum, apricot, peach, melon as well as achens and pulp separately of strawberry before and after X-ray irradiation are reported. Before irradiation all samples show in X band a weak singlet EPR line with g=2.0030±0.0005, except melon, which is EPR silent. Immediately after irradiation all samples exhibit complex fruit-depending spectra, which decay with time and change to give, in ca. 50 days, an asymmetric singlet EPR line with g=2.0041±0.0005. Only apricot pulp gave a typical "sugar-like" EPR spectrum. Singlet EPR lines recorded after irradiation in X -band are K- and Q-band resolved as typical anisotropic EPR spectra with g=2.0023±0.0003 and g⊥=2.0041±0.0005. In addition, K- and Q-band EPR spectra of all samples show a superposition with the six EPR lines of Mn 2+ naturally present in the fruits. The saturation behavior of the EPR spectra of achens of lyophilized and fresh strawberry is also studied. The differences in g factors of samples before and after X-ray irradiation might be used for the identification of radiation processing of fruits in the case of pulp and the differences in the EPR saturation behavior might be used for the achens of strawberry.

Background: Xerostomia is the most prominent complication in patients with head and neck carcinoma after radiotherapy (RT). Diffusion-weighted magnetic resonance imaging (DWI) with gustatory stimulation may contribute to the evaluation of salivary gland function. Purpose: To investigate the value of DWI for quantifying physiological changes of the parotid gland during gustatory stimulation in patients before and after RT. Material and Methods: Magnetic resonance imaging (MRI) was performed in 28 consecutive patients with nasopharyngeal carcinoma before and after RT and clinical xerostomia was also assessed. A DWI sequence was performed once at rest and continually repeated seven times during stimulation with ascorbic acid. Apparent diffusion coefficient (ADC) maps for parotid glands at different time points and the range of increase with stimulation were calculated. Paired two-tailed Student t tests were used to compare the ADC values before and after stimulation, and before and after RT. Results: Before RT, the ADC showed an initial increase (P<0.001) and then fluctuated during stimulation. After RT, as the clinical xerostomia changed from Grade 0 to Grade 2, the mean ADC at rest increased compared with the pre-RT value (P<0.001). A similar response to stimulation was observed, but the range of increase between the maximum ADC during stimulation and the baseline value at rest was higher post-RT than pre-RT (P=0.022). The minimum ADC during stimulation was higher than the baseline value post-RT (P=0.028), but there was no difference pre-RT (P=0.603). Conclusion: DWI combined with gustatory stimulation seems to display the physiological changes of the parotid gland following RT and may be a potential tool for non-invasively assessing salivary gland function

Infinitival before and after-clauses in European Portuguese: temporal and aspectual properties

Directory of Open Access Journals (Sweden)

2015-06-01

Full Text Available The main goal of this paper is to discuss temporal and aspectual features of sentences with clauses introduced by the connectives antes de + Infinitivo (‘before’ + Infinitive and depois de + Infinitivo (‘after’ + Infinitive combined with situations in the Pretérito Perfeito in European Portuguese. Our discussion is based on the widespread view that these clauses are locating adverbials (cf. Kamp and Reyle (1993 with temporal information of anteriority, in the case of antes de, and posteriority, in the case of depois de. However, this analysis is not as straightforward as one would expect, because, while before-clauses consistently render the same temporal relation (of anteriority, after-clauses may convey a temporal relation of inclusion, in addition to the standard posteriority relation. We put forward the hypothesis that aspectual characteristics play an important role in these differences, insofar as allowing a temporal reading that at first sight is not predicted from the semantic nature of the connective. In order to maintain a uniform treatment of before and after-clauses with respect to their temporal features, accounting simultaneously for the differences that emerge in their linguistic behaviour, we claim, along with Beaver & Condoravdi (2003 and Condoravdi (2010, that the locating time interval provided by these clauses is bounded to the left, but not to the right, that is, what is focused is the initial frontier of the situation that provides the time interval, leaving the final one undetermined. Furthermore, we show that, although the temporal mechanisms are parallel, the interference of aspectual properties leads to interesting differences in the final interpretation of before and after-sentences.

Breast cancer is usually present for many years (as long as 5-10 years) before it can be clinically diagnosed (theory of the 'dormant malignant cell'). This implies that breast cancer cells, during their subclinical period, are likely to have been exposed for a considerable time to endogenous sex hormones and endogenous hormonal milieu predicts the chances of breast cancer in females. So, we planned this study to evaluate the role of endogenous hormones in postmenopausal females excluding the patients on hormone replacement therapy as the relationship between breast cancer and hormone replacement therapy is well known. Hormone therapy is known to affect these hormone levels but whether treatment of breast cancer per se also decreases the hormone levels is not known. We planned the present study to determine hormone levels in patients before and after 4 months of treatment (chemotherapy/surgery and radiotherapy). Circulating hormone levels were measured using a chemiluminescence method. Their results were compared with a group of 25 age matched healthy controls. We found that serum prolactin, testosterone and estrogen levels were very significantly higher in patients before treatment (Group I) as compared to controls (Group III). Serum prolactin and serum estrogen levels were significantly higher and serum testosterone was very significantly higher in patients before treatment (Group I) when compared after 4 months of treatment (Group II). Only serum estrogen levels were significantly high in patients after treatment (Group II) as compared to controls (Group III). Serum progesterone levels showed no significant difference to any of the groups. We concluded that postmenopausal females with breast cancer have abnormalities in hormone levels. These abnormalities may be considered in the pathogenesis of the disease and should be taken into account in the treatment of patients of breast cancer. It might also be helpful to delay the onset of cancer by normalizing the

Full Text Available ABSTRACT CONTEXT AND OBJECTIVE: Bariatric surgery has been an effective alternative treatment for morbid obesity and has resulted in decreased mortality, better control over comorbidities and reduced use of drugs. The objective of this study was to analyze the impact of bariatric surgery on medication drug and nutritional supplement use. DESIGN AND SETTING: Longitudinal study of before-and-after type, on 69 morbidly obese patients in a public hospital in Porto Alegre. METHODS: Through interviews, the presence of comorbidities and use of drugs with and without prescription were evaluated. RESULTS: Among the 69 patients interviewed, 85.5% had comorbidities in the preoperative period, with an average of 2.3 (± 1.5 per patient. The main comorbidities reported were hypertension, diabetes and dyslipidemia. 84.1% of the patients were using prescribed drugs in the preoperative period. The mean drug use per patient was 4.8, which decreased to 4.4 after the procedure. The surgery enabled significant reduction in use of most antidiabetic (84%, antilipemic (77% and antihypertensive drugs (49.5%. On the other hand, there was a significant increase in use of multivitamins and drugs for disorders of the gastrointestinal tract. The dosages of most of the drugs that continued to be prescribed after surgery were decreased, but not significantly. CONCLUSION: After bariatric surgery, there were increases in the use of vitamins, gastric antisecretory drugs and antianemic drugs. Nevertheless, there was an overall reduction in drug use during this period, caused by suspension of drugs or dose reduction.

Obesity is one of the most common chronic diseases with important medical effects, as well as mental and social health problems. Bariatric surgery is one of the most effective treatments of morbid obesity. Because of the possible psychological changes, and its effects on weight loss after surgery, the current study aimed to compare marital satisfaction and self-confidence in patients with obesity before and after bariatric surgery in Rasoul-e-Akram hospital in 2013. This prospective observational study was conducted on 69 candidates for bariatric surgery. Marital satisfaction and self-confidence were assessed before and six months after the surgery by Enrich marital satisfaction scale and Coopersmith self-esteem inventory. Descriptive statistics and T-tests were utilized to analyze data. Values of P ≤ 0.01 were considered statistically significant. Despite the improvement of sexual relationship, marital satisfaction scores significantly decreased from141.26 ± 12.75 to 139.42 ± 12.52 six months after the surgery (P = 0.002). Satisfaction in scales of conflict resolution and communication showed a descending pattern (P self-esteem before and after the surgery (P = 0.321). Weight loss after bariatric surgery did not improve self-esteem and marital satisfaction six months post operatively; therefore, psychiatric assessment of patients before and after the surgery is crucial; since even if they are not associated with prognosis of the surgery, it is important to provide treatment for psychiatric problems. Prospective studies are recommended to assess post-operative changes of other psychological aspects.

To clarify the relationship between masticatory performance and oral health-related quality of life (OHRQoL) before and after complete denture treatment. Thirty patients wearing complete dentures were asked to chew a gummy jelly on their habitual chewing side, and the amount of glucose extraction during chewing was measured as the parameter of masticatory performance. Subjects were asked to answer the Oral Health Impact Profile (OHIP-J49) questionnaire, which consists of 49 questions related to oral problems. The total score of 49 question items along with individual domain scores within the seven domains (functional limitation, pain, psychological discomfort, physical disability, psychological disability, social disability and handicap) were calculated and used as the parameters of OHRQoL. These records were obtained before treatment and 3 months after treatment. Each parameter of masticatory performance and OHRQoL was compared before treatment and after treatment. The relationship between masticatory performance and OHRQoL was investigated, and a stepwise multiple linear regression analysis was performed. Both masticatory performance and OHRQoL were significantly improved after treatment. Furthermore, masticatory performance was significantly correlated with some parameters of OHRQoL. The stepwise multiple linear regression analysis showed functional limitation and pain as important factors affecting masticatory performance before treatment and functional limitation as important factors affecting masticatory performance after treatment. These results suggested that masticatory performance and OHRQoL are significantly improved after treatment and that there is a close relationship between the two. Moreover, functional limitation was found to be the most important factor affecting masticatory performance. Copyright © 2018 Japan Prosthodontic Society. Published by Elsevier Ltd.

BACKGROUND Interaction between maternal obesity, intrauterine environment and adverse clinical outcomes of newborns has been described. METHODS Using statewide birth certificate data, this retrospective, matched-control cohort study compared paired birth weights and complications of infants born to women before and after Roux-en-Y gastric bypass surgery (RYGB) and to matched obese non-operated women in several different groups. Women who had given birth to a child before and after RYGB (group 1; n = 295 matches) and women with pregnancies after RYGB (group 2; n = 764 matches) were matched to non-operated women based on age, body mass index (BMI) prior to both pregnancy and RYGB, mother’s race, year of mother/s birth, date of infant births and birth order. In addition, birth weights of 13 143 live births before and/or after RYGB of their mothers (n = 5819) were compared (group 3). RESULTS Odds ratios (ORs) for having a large-for-gestational-age (LGA) neonate were significantly less after RYGB than for non-surgical mothers: ORs for groups 1 and 2 were 0.19 (0.08–0.38) and 0.33 (0.21–0.51), respectively. In contrast, ORs in all three groups for risk of having a small for gestational age (SGA) neonate were greater for RYGB mothers compared to non-surgical mothers (ORs were 2.16 (1.00–5.04); 2.16 (1.43–3.32); and 2.25 (1.89–2.69), respectively). Neonatal complications were not different for group 1 RYGB and non-surgical women for the first pregnancy following RYGB. Pregnancy-induced hypertension and gestational diabetes were significantly lower for the first pregnancy of mothers following RYGB compared to matched pregnancies of non-surgical mothers. CONCLUSION Women who had undergone RYGB not only had lower risk for having an LGA neonate compared to BMI-matched mothers, but also had significantly higher risk for delivering an SGA neonate following RYGB. RYGB women were less likely than non-operated women to have pregnancy-related hypertension and diabetes

Coronal CT of the paranasal sinuses and the ostiomeatal complex (OMC) was performed before and 12 months after bilateral functional endoscopic sinus surgery (FESS) in 30 patients with sinusitis and 12 patients with nasal polyposis. The extent of sinus mucosal thickening was graded, and the patency of the OMC was evaluated. After FESS, the percentage of open OMCs had increased from 42% to 83% in the sinusitis group, and from 8% to 45% in the polyposis group. There was only a small improvement in mucosal score in sinuses with opened OMC, so that the overall extent of sinus opacification before and after FESS was almost the same. Despite this, 91% of the patients reported clinical relief of symptoms. Preoperative coronal CT of the paranasal sinuses serves as an anatomical map for the surgeon, but there is no benefit of routine postoperative CT. (orig.)

Ecotoxicity methods were used to assess different soil and oil combinations before, during and after laboratory bioremediation with associated hydrocarbon analyses. Heavy, medium and light crude oil (API gravity 14, 30 and 55) was spiked (ca. 5% w/w) into two sandy soils in the laboratory having organic carbon concentrations of 0.3 (Norwood) and 4.7% (Norwood/Baccto). The earthworm (Eisenia fetida) 14-d lethality assay, the modified Microbics Microtox Solid-Phase assay, and the 14-d plant seed germination and growth assays using corn, wheat and oats, were spiked and tested during a 360-d laboratory remediation. Eisenia was the most sensitive of the three methods utilised with survival increasing throughout bioremediation with fastest toxicity reduction in the high carbon Norwood/Baccto soils where LC50s were 100% or greater at the end of 90-d whereas, >150-d were required to achieve a similar result in the low carbon soil. Analysis of the undiluted treatments with oily soil alone showed that earthworm survival was high after 90-d in all high organic carbon soils, and after eight months in the low carbon soils, except for the Norwood soil-light oil treatment, which required 360-d to achieve 100% survival. The Microtox assay was less sensitive with EC50s 100% or greater observed after 90-d in high carbon soils and after 245-d for all low carbon soils. After bioremediation, no effects on seed germination were observed, although some plant growth inhibition effects remained. There was no direct correlation between total petroleum hydrocarbon concentrations and toxicity. (Author)

Copper flotation waste from copper production using a pyrometallurgical process contains toxic metals such as Cu, Zn, Co and Pb. Because of the presence of trace amounts of these highly toxic metals, copper flotation waste contributes to environmental pollution. In this study, the leaching characteristics of copper flotation waste from the Black Sea Copper Works in Samsun, Turkey have been investigated before and after vitrification. Samples obtained from the factory were subjected to toxicity tests such as the extraction procedure toxicity test (EP Tox), the toxicity characteristic leaching procedure (TCLP) and the "method A" extraction procedure of the American Society of Testing and Materials. The leaching tests showed that the content of some elements in the waste before vitrification exceed the regulatory limits and cannot be disposed of in the present form. Therefore, a stabilization or inertization treatment is necessary prior to disposal. Vitrification was found to stabilize heavy metals in the copper flotation waste successfully and leaching of these metals was largely reduced. Therefore, vitrification can be an acceptable method for disposal of copper flotation waste.

It is recommended that endotracheal cuff (ETTc) pressure be between 20 and 30 cm H 2 O. In this present study, we intend to observe average cuff pressure values in our clinic and the change in these values after the training seminar. The cuff pressure values of 200 patients intubated following general anesthesia induction in the operating theatre were measured following intubation. One hundred patients whose values were measured before the training seminar held for all physician assistants, and 100 patients whose values were measured after the training seminar were regarded as Group 1 and Group 2, respectively. Cuff pressures of both groups were recorded, and the difference between them was shown. Moreover, cuff pressure values were explored according to the working period of the physician assistants. There was no significant difference between the groups in terms of age, gender and tube diameters. Statistically significant difference was found between cuff pressure values before and after the training (p values decreased, however no statistically significant different was found (p values and potential complications.

This study aimed to assess the impact of a stethoscope disinfection sensitization campaign among doctors and nurses in a Nigerian teaching hospital. The design was a before-and-after study. Pre-program measurements were used to provide a baseline against which the post-program results were compared. Interventions that promoted compliance with stethoscope disinfection practice that were implemented included training and education on stethoscope disinfection and introduction of 70% isopropyl alcohol disinfectant at points-of-care places. Microbiological assessment of stethoscopes used by health workers was conducted after the intervention and the outcome was compared with the pilot study results. After the intervention, of the 89 stethoscopes screened, 18 (20.2%) were contaminated with bacterial agents. A higher prevalence of stethoscope contamination was observed among stethoscopes from the intensive care unit (66.7%), the VIP unit (50%), and the antenatal unit (37.5%). The main isolates were Staphylococcus aureus (44.4%) and Escherichia coli (50%). The antibiotic sensitivity assessment indicated that the bacterial isolates were resistant to nearly all the antibiotics tested. All the 89 health workers whose stethoscopes were screened after the intervention admitted to cleaning their stethoscopes after seeing each patient, representing a compliance rate of 100%, unlike the 15% compliance at the pilot phase. The baseline stethoscope contamination rate was 78.5% versus 20.2% post-intervention. Training and education and introduction of alcohol-based disinfectants inexpensive but very effective methods to improve stethoscope disinfection compliance among health workers in low-income settings.

Full Text Available For patients with pharmaco-resistant temporal epilepsy, unilateral anterior temporal lobectomy (ATL - i.e. the surgical resection of the hippocampus, the amygdala, the temporal pole and the most anterior part of the temporal gyri - is an efficient treatment. There is growing evidence that anterior regions of the temporal lobe are involved in the integration and short-term memorization of object-related sound properties. However, non-verbal auditory processing in patients with temporal lobe epilepsy (TLE has raised little attention. To assess non-verbal auditory cognition in patients with temporal epilepsy both before and after unilateral ATL, we developed a set of non-verbal auditory tests, including environmental sounds. We could evaluate auditory semantic identification, acoustic and object-related short-term memory, and sound extraction from a sound mixture. The performances of 26 TLE patients before and/or after ATL were compared to those of 18 healthy subjects. Patients before and after ATL were found to present with similar deficits in pitch retention, and in identification and short-term memorisation of environmental sounds, whereas not being impaired in basic acoustic processing compared to healthy subjects. It is most likely that the deficits observed before and after ATL are related to epileptic neuropathological processes. Therefore, in patients with drug-resistant TLE, ATL seems to significantly improve seizure control without producing additional auditory deficits.

To investigate the nutritional status of patients before and after hematopoietic stem cell transplantation (HSCT), and explore optimal methods for assessing nutritional status in patients with hematological diseases. This cohort study enrolled 170 patients who were diagnosed with hematological diseases and underwent allogeneic HSCT in the Department of Hematology, Peking University People's Hospital between May 2011 and April 2013. We used fixed-point continuous sampling and four nutritional screening tools, Nutritional Risk Screening 2002 (NRS-2002), Mini Nutritional Assessment (MNA), Subjective Global Assessment (SGA) and Malnutrition Universal Screening Tools (MUST), in combination with body measurements, to extensively screen and evaluate nutritional risks and status in patients receiving HSCT before entering and after leaving laminar air flow rooms. After HSCT, patients had significant reduction in weight, hip circumference, waist-hip ratio, calf circumference, mid-upper arm circumference, and suprailiac skinfold thickness compared with pre-HSCT measurements. Before HSCT, NRS-2002 identified that 21.2% of patients were at nutritional risks, compared with 100% after HSCT. MUST indicated that before HSCT, 11.77% of patients were at high nutritional risk, compared with 59.63% after HSCT. MNA assessed that 0.06% of patients were malnourished before HSCT, compared with 19.27% after HSCT. SGA identified that before HSCT, 1.76% of patients had mild to severe malnutrition, which increased to 83.3% after HSCT. There is a significant increase in the nutritional risk and malnutrition in patients who received HSCT. Before HSCT, some patients already had nutritional risk or nutritional deficiencies, and prompt and close nutritional screening or assessment should be performed. The nutritional status of patients after HSCT was generally deteriorated compared with that before transplantation. Body measurements should be taken more frequently during the subsequent treatment

X-, K- and Q-band EPR studies on lyophilized whole pulp parts of blue plum, apricot, peach, melon as well as achens and pulp separately of strawberry before and after X-ray irradiation are reported. Before irradiation all samples show in X band a weak singlet EPR line with g=2.0030+/-0.0005, except melon, which is EPR silent. Immediately after irradiation all samples exhibit complex fruit-depending spectra, which decay with time and change to give, in ca. 50days, an asymmetric singlet EPR line with g=2.0041+/-0.0005. Only apricot pulp gave a typical ''sugar-like'' EPR spectrum. Singlet EPR lines recorded after irradiation in X -band are K- and Q-band resolved as typical anisotropic EPR spectra with g{sub ||}=2.0023+/-0.0003 and g{sub -}bar =2.0041+/-0.0005. In addition, K- and Q-band EPR spectra of all samples show a superposition with the six EPR lines of Mn{sup 2+} naturally present in the fruits. The saturation behavior of the EPR spectra of achens of lyophilized and fresh strawberry is also studied. The differences in g factors of samples before and after X-ray irradiation might be used for the identification of radiation processing of fruits in the case of pulp and the differences in the EPR saturation behavior might be used for the achens of strawberry.

This study was designed to investigate the influence of surgical removal of a tumor-bearing urogenital organ on CAM use.Methods: From 2007 to 2011, 350 patients underwent major urological surgery for kidney, prostate, or bladder cancer at the Goethe-University Hospital, Frankfurt, Germany. Data from 172 patients (49%, who returned a questionnaire, were retrospectively evaluated using the hospital information system along with the questionnaire to objectify CAM use 2 years before and after surgery.Results: From the 172 patients returning questionnaires, 56 (33% used CAM before and/or after surgery and 116 (67% never used CAM. Of the 56 CAM users, 30 (54% used CAM presurgery and 53 (95% used CAM postsurgery, indicating a significant change of mind about CAM use. Patients of German nationality used CAM significantly more than patients of other nationalities. Higher educational status (high-school diploma or higher was a significant factor in favor of CAM use. The most common type of CAM used before/after surgery was an alternative medical system (63/49%, a manipulative and body-based method (50/19%, and a biological-based therapy (37/32%. Information about CAM, either provided by medical professionals or by other sources, was the main reason determining whether patients used CAM or not.Conclusion: The number of patients using CAM almost doubled after surgical removal of a cancer-bearing organ.

Iron deficiency and anemia are changes often associated with obesity. Bariatric surgery is responsible for increasing the iron loss and reducing its absorption. The objective of this study was to evaluate anemia and iron deficiency before and after bariatric surgery and to relate them to possible predisposing factors. A retrospective study was conducted on obese patients submitted to open Roux-en-Y gastric bypass, in which clinical and laboratory data were obtained up to 48 months postoperatively. Patients were divided into groups according to the presence or absence of anemia and to the presence or absence of iron deficiency (even without anemia), and all data were compared between these groups. Preoperatively, 21.5% of patients had anemia and 20% had iron deficiency. The number of patients with anemia did not vary through the 4 years of the study, but ferritin levels significantly decreased with time (Panemia. Female gender was a variable associated with a greater incidence of iron deficiency. Anemia and iron deficiency are frequent in obese patients and must be treated before surgery. Medical and nutritional surveillance is important in the postoperative period of bariatric surgery. Management of each condition must be directed at correcting the 2 major sources of iron deficiency and anemia: food intolerance (mostly meat intolerance) and losses (frequently due to menstruation). These are the factors more related to iron deficient anemia. Copyright © 2014 American Society for Bariatric Surgery. Published by Elsevier Inc. All rights reserved.

In 2012, North Dakota enacted a comprehensive statewide law prohibiting smoking in enclosed public places. Disparities in tobacco control exist in rural areas. This study's objective was to determine the extent to which the passage of a comprehensive, statewide, smoke-free law in a predominantly rural state influenced tobacco smoke pollution in rural and nonrural venues. A longitudinal cohort design study comparing the levels of tobacco smoke pollution before and after passage of the statewide smoke-free law was conducted in 64 restaurants and bars statewide in North Dakota. Particulate matter with a median aerodynamic diameter of <2.5 μm (a valid atmospheric marker of tobacco smoke pollution) was assessed. A significant 83% reduction in tobacco smoke pollution levels occurred after passage of the law. Significant reductions in tobacco smoke pollution levels occurred in each of the rural categories; however, no difference by rurality was noted in the analysis after passage of the law, in contrast to the study before passage. To our knowledge, this was the largest, single, rural postlaw study globally. A comprehensive statewide smoke-free law implemented in North Dakota dramatically decreased the level of tobacco smoke pollution in bars and restaurants. © 2016 The Authors.

99m Tc-DMSA scintigraphy was carried out in 43 patients with unilateral renal stones before and after PNL. This study was repeated about one year after PNL in 12 patients. DMSA renal uptake was calculated two hours after injection of 99m Tc-DMSA. The study was performed using the dual type gamma camera. The renal function was assessed by the formula : 99m Tc-DMSA renal uptake of the operated side/ 99m Tc-DMSA renal uptake of the contralateral side. The change (ratio before/after PNL) x 100 was regarded as the percent change of renal function. Local abnormalities in the 99m Tc-DMSA renal scintigram after PNL were observed in 15 patients. The renal function decreased significantly to 95.8 ± 8.7 % from the base line 4 - 8 weeks after PNL. The renal function improved significantly to 98.6 ± 14.7 % from 92.1 ± 11.9 % in 12 patients about one year after PNL. It is concluded that although the renal function slightly decreased 4 - 8 weeks after PNL, it is expected to improve within 1 year after PNL. 99M Tc-DMSA scintigraphy is a useful adjunct to evaluate the renal function before and after PNL.

Mid-frontal and mid-lateral (F3/F4 and F7/F8) EEG asymmetry has been associated with motivation and affect. We examined alpha EEG asymmetry in depressed and healthy participants before and after Behavioral Activation treatment for depression; examined the association between alpha EEG asymmetry and motivational systems and affect; and evaluated the utility of alpha EEG asymmetry in predicting remission. Depressed (n=37) and healthy participants (n=35) were assessed before and after treatment using a clinical interview, a task to measure baseline EEG, and questionnaires of behavioral activation and inhibition, avoidance, and affect. Alpha EEG asymmetry was significantly higher in depressed than healthy participants at pre-treatment, positively correlated with negative affect and behavioral inhibition, and inversely correlated with lower behavioral activation sensitivity. Heightened alpha EEG asymmetry in depressed participants was significantly associated with increased behavioral inhibition and negative emotion and was independent of clinical remission.

We examined how alcohol risk is distributed based on college students' drinking before, during and after they go to certain settings. Students attending 14 California public universities (N=10,152) completed a web-based or mailed survey in the fall 2003 semester, which included questions about how many drinks they consumed before, during and after the last time they went to six settings/events: fraternity or sorority party, residence hall party, campus event (e.g. football game), off-campus party, bar/restaurant and outdoor setting (referent). Multi-level analyses were conducted in hierarchical linear modeling (HLM) to examine relationships between type of setting and level of alcohol use before, during and after going to the setting, and possible age and gender differences in these relationships. Drinking episodes (N=24,207) were level 1 units, students were level 2 units and colleges were level 3 units. The highest drinking levels were observed during all settings/events except campus events, with the highest number of drinks being consumed at off-campus parties, followed by residence hall and fraternity/sorority parties. The number of drinks consumed before a fraternity/sorority party was higher than other settings/events. Age group and gender differences in relationships between type of setting/event and 'before,''during' and 'after' drinking levels also were observed. For example, going to a bar/restaurant (relative to an outdoor setting) was positively associated with 'during' drinks among students of legal drinking age while no relationship was observed for underage students. Findings of this study indicate differences in the extent to which college settings are associated with student drinking levels before, during and after related events, and may have implications for intervention strategies targeting different types of settings.

To determine patterns of blood glucose monitoring in children and adolescents with type 1 diabetes (T1D) before and after routine T1D clinic visits. Blood glucose monitoring data were downloaded at four consecutive routine clinic visits from children and adolescents aged 5-18 years. Linear mixed models were used to analyze patterns of blood glucose monitoring in patients who had at least 28 days of data stored in their blood glucose monitors. In general, the frequency of blood glucose monitoring decreased across visits, and younger children engaged in more frequent blood glucose monitoring. Blood glucose monitoring increased before the T1D clinic visits in younger children, but not in adolescents. It declined after the visit regardless of age. Members of the T1D care team need to consider that a T1D clinic visit may prompt an increase in blood glucose monitoring when making treatment changes and recommendations. Tailored interventions are needed to maintain that higher level of adherence across time. © The Author(s) 2017. Published by Oxford University Press on behalf of the Society of Pediatric Psychology.

2006-07-01

Full Text Available Introduction & Objective: Electroconvulsive therapy (ECT is used widely in psychiatric practice. The goal of anesthesia for ECT is the prevention of complications such as discomfort, fractures, aspiration of gastric contents and hypoxia. However, general anesthesia can cause some adverse effects as hypoxia. Prevention and treatment of hypoxia is important due to its undesirable effects on seizure duration and cardiovascular system. This study was designed to detect the incidence and probable times of desaturation in patients receiving ECT. Materials & Methods: This prospective randomized clinical trial was carried out on 100 patients (18-50 y/o with ASA I or II who were scheduled for ECT. After pre-oxygenation and similar anesthesia induction the patients received ECT. The patients were ventilated by oxygen and face masked until the return of their spontaneous respiration with adequate tidal volume and respiratory rate. Then they were transferred to recovery room where there was no oxygen supplementation. Oxygen saturation was measured by a Nell core pulse oximeter and was recorded at six stages: before and after anesthesia induction, during ECT, after ECT, 5 minutes after entering recovery room and before leaving there. The data were analyzed by standard statistical tests using SPSS software Results: Data analysis revealed that desaturation was not noticed at any stage except for the 5th stage (5 minutes after entering recovery room, when 13% of patients developed Sao2% less than 90%. Also there was a significant difference between Sao2% of patients between this stage (5th and other stages (p<0.001. Conclusion: According to our findings, appropriate oxygen supplementation and pulse oximetry monitoring during recovery period after ECT can be recommend

The necessity of endometriosis dynamics evaluation is caused by worse ecological situation on the area of Belarus. Genital endometriosis frequency was studied considering the outcomes of surgeries fulfilled in hospitals of Gomel, Mogilev and Vitebsk in 1981-1995. At this time 1254 women underwent an operation and 19% of patients (235 persons) were operated before the Chernobyl accident. In the first 5 years after the accident endometriosis frequency increased nearly 2 times. The next 5 years (1991-1995) the number of operated patients was 565, i.e. 45% from the whole number. Uterus was extirpated or amputated in 898 patients, ovaries at both sides were removed in 36 ones. As the analysis showed the endometriosis frequency grew in 2,5 times for last 15 years, the most significant increase of this pathology was observed during the first five years after the accident

Full Text Available INTRODUCTION: Morbid obesity has multiple implications for psychological and physical health. Bariatric surgery has been selected as the treatment of choice for this chronic disease, despite the controversial impact of the surgery on psychosocial health. The objective of this study was to describe candidates for bariatric surgery and analyze changes in weight, psychopathology, personality, and health problems and complaints at 6- and 12- month follow-up assessments. METHODS: Thirty obese patients (20 women and 10 men with a mean age of 39.17±8.81 years were evaluated in different dimensions before surgery and 6 and 12 months after the procedure. RESULTS: Six and 12 months after bariatric surgery, patients reported significant weight loss and a significant reduction in the number of health problems and complaints. The rates of self-reported psychopathology were low before surgery, and there were no statistically significant changes over time. The conscientiousness, extraversion, and agreeableness dimensions increased, but neuroticism and openness remained unchanged. All changes had a medium effect size. CONCLUSIONS: Our results suggest that patients experience significant health improvements and some positive personality changes after bariatric surgery. Even though these findings underscore the role of bariatric surgery as a relevant treatment for morbid obesity, more in-depth longitudinal studies are needed to elucidate the evolution of patients after the procedure.

Full Text Available Abstract Introduction: Recently virtual reality has been aggregated to the therapeutic possibilities for patients who need functionality gains, such as individuals with cerebral palsy (CP. Aim: to evaluate the effects of virtual reality on the gross motor function of individuals with CP. Methods: longitudinal study, realized in a special education school, with five individuals with CP (7.4 years of age ± 1.14 of both sexes, evaluated using the B, D and E dimensions of the GMFM 88, before and after the application of three Wii Fit Plus(r console games: Hula Hoop, Slide Penguin and Soccer Heading. These games were applied for four minutes per game, at the beginner level, twice a week, for twelve consecutives weeks. The normality of the sample was evaluated through the Shapiro-Wilk's test. The results obtained before and after the Wii Fit(r application were compared using descriptive statistics. Results: all the individuals obtained improvements in the dimensions evaluated after the virtual reality application, with a 5.14% general improvement, varying between 1.9% and 9.6%. The standing (D and walking, running and jumping (E dimensions were the dimensions which obtained higher improvement percentages. Conclusion: considering the study limitations, the results obtained suggest that virtual reality can promote benefits in the gross motor function of individuals with cerebral palsy.

To correlate the decrease in background parenchymal enhancement (BPE) and tumour response measured with MRI in breast cancer patients treated with neoadjuvant chemotherapy (NAC). One hundred and forty-six MRI examinations of 73 patients with 80 biopsy-proven breast cancers who underwent breast MRI before and after NAC were retrospectively analysed. All images were reviewed by two blinded readers, who classified BPE into categories (BEC; 1 = minimal, 2 = mild, 3 = moderate, 4 = marked) before and after NAC. Histopathological and morphological tumour responses were analysed and compared. The distribution of BEC 1/2/3/4 was 25/46/18/11 % before and 78/20/2/0 % after NAC. On average, BPE decreased by 0.87 BEC. Cohen's kappa showed substantial agreement (k = 0.73-0.77) before and moderate agreement (k = 0.43-0.60) after NAC and moderate agreement (k = 0.62-0.60) concerning the change in BEC. Correlating the change in BPE with tumour response, the average decrease in BEC was 1.3 in cases of complete remission, 0.83 in cases with partial response, 0.85 in cases with stable disease and 0.40 in cases with progressive disease. Correlation analysis showed a significant correlation between the decrease in BEC and tumour response (r = -0.24, p = 0.03). BPE decreased by, on average, 0.87 BEC following NAC for breast cancer. The degree of BPE reduction seemed to correlate with tumour response. (orig.)

In Taiwan, the Smoke-Free Restaurant Program (SFRP) was implemented from 2003 to 2005 as an initial phase before the introduction of restrictive legislation promoting smoke-free restaurants (SFRs). No studies have evaluated trends in public opinion before and after a national health promotion campaign for the introduction of SFRs on a voluntary basis. The present study investigated whether public opinion with respect to eliminating environmental tobacco smoke (ETS) in restaurants changed after implementation of the SFRP. Data were obtained from four large-scale, nationally representative surveys conducted in 2003-2005 before and after implementation of the SFRP. Weighted analyses were performed to obtain nationally representative results. After a series of SFRP campaigns, reported exposure to ETS in restaurants by survey participants decreased by approximately 14%. Approximately 20% more people had heard of SFRs, and approximately 25% more had chosen to dine in a smoke-free restaurant. We found consistently high community support for SFRs (ca. 95%), and approximately 80% supported smoke-free restaurant legislation, although both rates dropped slightly in 2005. People aged 60 years or more, nonsmokers, and those who had greater knowledge of ETS hazards were more likely to support smoke-free restaurant legislation. The SFRP was effective at promoting SFRs on a voluntary basis. Strong community endorsement has major implications for legislators who are considering the nature and extent of further smoke-free restaurant legislation in Taiwan and other countries.

Full Text Available This study analyzes data regarding cross-fault deformations within the seismogenic zone of the 2016 Qinghai Menyuan Ms6.4 earthquake and its surrounding area. The results showed that the tendency anomaly sites near the epicenter had relatively long anomaly durations prior to the earthquake, while sudden-jumping anomaly sites started to increase in the middle eastern Qilian Mountains approximately a year before the earthquake and continued to increase and migrate towards the vicinity of the epicenter two to six months before the earthquake. Intensive observations a few days after the earthquake indicated that abnormal returns and turns before the earthquake were significant, but all had small amplitudes, and the coseismic effect was generally minor. In addition, the post-seismic tendency analysis of individual cross faults in the Qilian Mountain fault zone revealed an accelerating thrust tendency at all cross-fault sites in the middle Qilian Mountains after the 2008 Wenchuan Ms8.0 earthquake. This indicates that the Wenchuan mega-earthquake exerted a great impact on the dynamic environment of the northeastern margin of the Qinghai-Tibet plate and significantly enhanced the extrusion effect of the Indian plate on the middle Qilian Mountains, generating favorable conditions for the occurrence of Menyuan thrust earthquakes.

Full Text Available Abstract Background Inflammation is implicated in causing diabetes. We tested whether transcription factor 7 like-2 (TCF7L2 gene polymorphisms (rs12255372 and rs7903146, consistently associated with type 2 diabetes, are associated with plasma concentrations of inflammatory markers before and after three weeks of daily treatment with fenofibrate. Methods Men and women in the Genetics of Lipid-Lowering Drugs and Diet Network study (n = 1025, age 49 ± 16 y were included. All participants suspended use of lipid-lowering drugs for three weeks and were then given 160 mg/day of fenofibrate for three weeks. Inflammatory markers and lipids were measured before and after fenofibrate. ANOVA was used to test for differences across TCF7L2 genotypes. Results Under the additive or dominant model, there were no significant differences (P > 0.05 in the concentrations of inflammatory markers (hsCRP, IL-2, IL-6, TNF-α and MCP-1 across TCF7L2 genotypes in the period before or after treatment. For both rs12255372 and rs7903146, homozygote T-allele carriers had significantly higher (P Conclusion Overall these data show no association between TCF7L2 polymorphisms and the inflammatory markers suggesting that the effects of TCF7L2 on diabetes may not be via inflammation.

Quality of life (QoL) is a well-established outcome measure. In contrast to adult obsessive-compulsive disorder (OCD), little is known about the effects of treatment on QoL in children with OCD. This study aimed to assess QoL after cognitive behavioural therapy (CBT) in children and adolescents with OCD compared with the general population and to explore factors associated with potential changes in QoL after treatment. QoL was assessed in 135 children and adolescents (ages 7-17; mean 13 [SD 2.7] years; 48.1% female) before and after 14 CBT sessions, using self-report and a caregivers proxy report of the Questionnaire for Measuring Health-related Quality of Life in Children and Adolescents (KINDL-R). QoL was compared with an age- and gender-matched sample from the general population. Before treatment, QoL was markedly lower in children with OCD compared with the general population. QoL improved significantly in CBT responders (mean score change 7.4), to the same range as QoL in the general population. Non-responders reported no QoL changes after treatment, except for one patient. Comorbidity, family accommodation and psychosocial functioning were not associated with changes in QoL after treatment. To our knowledge, this is the first study of the changes in QoL after treatment of paediatric OCD. The assessment of QoL beyond symptoms and function in children with OCD has been shown to be reliable and informative. The results of this study support the application of QoL assessment as an additional measure of treatment outcome in children and adolescents with OCD.

Despite the continuous development of materials and techniques of adhesive bonding, the basic procedure remains relatively constant. The technique is based on three components: etching substance, adhesive system, and composite material. The use of etchants during bonding orthodontic brackets carries the risk of damage to the enamel. Therefore, the article examines the effect of the manner of enamel etching on its thickness before and after orthodontic treatment. The study was carried out in vitro on a group of 80 teeth. It was divided into two subgroups of 40 teeth each. The procedure of enamel etching was performed under laboratory conditions. In the first subgroup, the classic method of enamel etching and the fifth-generation bonding system were used. In the second subgroup, the seventh-generation (self-etching) bonding system was used. In both groups, metal orthodontic brackets were fixed and the enamel was cleaned with a cutter fixed on the micromotor after their removal. Before and after the treatment, two-dimensional optical coherence tomography scans were performed. The enamel thickness was assessed on the two-dimensional scans. The average enamel thickness in both subgroups was not statistically significant. PMID:28243604

This study was designed to show the effect of propylthiouracil treatment on sCD40L, high-sensitivity C-reactive protein, and fetuin-A levels on subjects with subclinical hyperthyroidism. After checking sCD40L, high-sensitivity C-reactive protein, and fetuin-A levels of 35 patients with subclinical hyperthyroidism, each was given 50 mg tablets of propylthiouracil three times daily. After 3 months, sCD40L, high-sensitivity C-reactive protein, and fetuin-A levels were then compared to the levels before treatment. Although high-sensitivity C-reactive protein and sCD40L levels were normal in the subclinical hyperthyroidism patients compared to the healthy controls, fetuin-A levels were statistically significantly higher (*p = 0.022). After treatment, fetuin-A levels of subclinical hyperthyroidism patients decreased statistically significantly compared to the levels before treatment (**p = 0.026). sCD40L and high-sensitivity C-reactive protein levels did not have a statistically significant difference compared to the control group and post-propylthiouracil treatment. In subclinical hyperthyroidism patients, high fetuin-A levels before propylthiouracil treatment and decreases in these levels after treatment in cases with subclinical hyperthyroidism indicated the possibility of preventing long-term cardiac complications with propylthiouracil treatment.

The aim of this study was to describe stress symptoms among adolescents before and after scoliosis surgery and to explore correlations with postoperative pain. Scoliosis surgery is a major surgical procedure. Adolescent patients suffer from preoperative stress and severe postoperative pain. Previous studies indicate that there is a risk of traumatisation and psychological complications during the recovery period. A prospective quantitative cohort study with consecutive inclusion of participants. A cohort of 37 adolescent patients aged 13-18. To assess the adolescents' experiences before surgery and at six to eight months after surgery, the Trauma Symptom Checklist for Children - Alternative version, Youth Self-Report and Kiddie Schedule for Affective Disorder and Schizophrenia for children 12-18 were used. The Visual Analogue Scale was used for self-report of postoperative pain on day three. Rates of anxiety/depression and internalising behaviour were significantly higher before surgery than six months after. Preoperative anger, social problems and attention problems correlated significantly with postoperative pain on day three. At follow-up, postoperative pain correlated significantly with anxiety, social problems and attention problems. The results of this study indicate a need for interventions to reduce perioperative stress and postoperative pain to improve the quality of nursing care. Attention to preoperative stress and implementation of interventions to decrease stress symptoms could ameliorate the perioperative process by reducing levels of postoperative pain, anxiety, social and attention problems in the recovery period. © 2016 John Wiley & Sons Ltd.

Full Text Available Adenoids and tonsils are active lymphoid organs and play an important role ‎against invading antigens of upper aerodigestive tract in children. ‎The present study analyzes the changes in cellular and humoral immunity of children six ‎months after adenotonsillectomy. The study population consisted of 30 children whit chronic adenotonsillar hypertrophy and 30 age-matched healthy children. ‎In all children serum level of IgM and IgG, percentage of T lymphocytes (CD3, T ‎helper cells (CD4, T cytotoxic ‎cells (CD8 and B lymphocytes (CD20 were measured before surgery. These parameters were ‎remeasured in patients 6 months after adenotonsillectomy. ‎Before the operation, a reduction in percentage of T lymphocytes (CD3,TCD4,TC8 ‎and B CD20 was seen compared to control group. This reduction was only significant in T ‎lymphocytes (CD3.The serum IgM and IgG levels were not different in two groups. Six months after ‎operation, the percentage of lymphocytes T CD3, T CD8 and BCD20 was increased and ‎reached the control group. The IgM level was also significantly decreased in patients after ‎operation. ‎Our results indicate that cellular and humoral immunity decreases in children ‎with chronic adenotonsiller hypertrophy preoperatively and increases to healthy children ‎level, six months postoperatively. It means that chronic adenotosillar hypertrophy affect ‎some parameters of cellular and humoral immunity and adenotonsillectomy by removing ‎chronic stimulations and reverses these changes without any negative effect on immune ‎function of patients.

The calcium endocrine system of nonhuman primates can be influenced by chairing for safety and the weightless environment of spaceflight. The serum of two rhesus monkeys flown on the Bion 11 mission was assayed pre- and postflight for vitamin D metabolites, parathyroid hormone, calcitonin, parameters of calcium homeostasis, cortisol, and indexes of renal function. Results were compared with the same measures from five monkeys before and after chairing for a flight simulation study. Concentrations of 1,25-dihydroxyvitamin D were 72% lower after the flight than before, and more than after chairing on the ground (57%, P endocrine system were similar to the effects of chairing on the ground, but were more pronounced. Reduced intestinal calcium absorption, losses in body weight, increases in cortisol, and higher postflight blood urea nitrogen were the changes in flight monkeys that distinguished them from the flight simulation study animals.

All patients but one recovered from symptoms after core decompression. Although the signal morphology of the necrotic area remained unchanged in the majority of the cases, a decrease of the joint effusion was observed as well as an ongoing signal increase after gadopentetate dimeglumine application. The last examinations displayed similar signal characteristics as on the preoperative scans; however, a reduction of the necrotic zone became evident. (orig./MG) [de

Objective We aimed to compare the medical students’ attitude towards psychiatry before and after psychiatry clerkship, and to examine the association of choosing psychiatry as a future career with some personal characteristics. Method In a self-controlled, quasi-experimental study, all of the medical students entering the psychiatry clerkship in three major medical schools of Iran located in Tehran (Tehran, Shahid Beheshti, and Iran University of Medical Sciences) were asked to participate anonymously in the study on the first and the last 3-days of their psychiatry clerkship. From 346 invited 4th-5th year medical students, 225 (65%) completed anonymous self-report questionnaires before and after a 4-week psychiatry clerkship. Results Positive response to choose psychiatry as a career was seen in 13.3% and 18.3% before and after psychiatry rotation, respectively. However, the difference was not statistically significant; about one-quarter of the students were turned on to psychiatry and 25% were discouraged during the clerkship. Individual pair wise comparisons revealed significant improvements only in two out of 13 measured aspects of psychiatry. Seventeen out of 38 (47.7%) students who identified psychiatry as the career of choice or strong possibility reported that one of their family members or close friends’ mental illness had an impact on their choice. Those students who considered psychiatry as the strong possibility claimed that they are more interested in humanities (OR = 2.96; 95% CI: 1.17, 7.49), and playing a musical instrument (OR = 2.53; 95% CI: 1.15, 5.57). Conclusion It may be concluded that exposure to psychiatry clerkship could influence medical students’ opinion about psychiatry positively, or negatively. Personal characteristics and individual interests of students may play an important role in choosing psychiatry as their future career. PMID:23682250

Acromegaly is a disease caused by a benign pituitary tumor producing excess amount of growth hormone. A changed body composition can be a functional parameter of the disorder. The aim of this study is to describe body composition in acromegaly before and after therapy. Total body potassium (TBK) was measured as total exchangeable potassium using 42 K by dilution technique or by counting gamma radiation from the naturally present 40 K in a high sensitivity 3π whole body counter. Total body water (TBW) was determined with an isotope dilution technique using tritiated water as a tracer. The specific activity was measured in urine or plasma. The predicted values for TBK, TBW, and body fat (BF) were calculated by equations using body weight (BW), body height, age and sex as independent variables. The normal values for BW were calculated by using body height and sex as independent variables

Full Text Available To determine the prevalence of pre and post prostatectomy related urinary tract in-fection and its correlation with peri-operative events, we studied 120 patients who underwent pros-tatectomy due to benign prostatic hypertrophy from September 2005 to September 2006. Urine cultures were performed before the operations, after a week, and three months later. Data including prostate volume, prostatic specific antigen (PSA, post voiding residue (PVR and histopathological reports as well as the duration of urinary leak, bladder irrigation, hospitalization, and catheterization were studied. The mean age of the studied patients was 70.5 ± 8 years. Significant preoperative bac-teriuria was revealed in 18 (15% patients of whom 14(77% patients developed negative cultures following the operation. Postoperative bacteriuria was detected in 9(7.5% patients who negative urine cultures preoperatively. Pre and post operative micro-organisms were different in the majority of the cases. The mean PSA was higher in patients with a positive history of infection. Following prostatectomy, patients with positive urine cultures had significantly longer urinary leakage, cathe-terization, and hospital stays compared with those who remained culture negative. We conclude that the incidence of positive urine culture pri-prostatectomy for BPH can be improved by appropriate antibiotic therapy, and the risk factors for postoperative urinary infection include preoperative infec-tion, prolonged urinary leakage, catheterization, and hospital stay. The elevated PSA may be a risk factor.

The health care costs of kidney transplantation and dialysis are generally unknown. This study estimates the Swedish health care costs of kidney transplantation and dialysis over 10 years from a health care perspective. A before-after design was used, in which the patients served as their own controls. Health care costs the year before transplantation were assumed to continue in the absence of a transplant and the cost savings was therefore calculated as the difference between the expected costs and the actual costs during the 10-year follow-up period. Factors associated with the size of the cost savings were studied using ordinary least-squares regression. Altogether 66-79% of the expected health care costs over 10 years were avoided through kidney transplantation, resulting in a cost savings of €380 000 (2012 price-year) per patient. Savings were the highest for successful transplantations, but on average the treatment was cost-saving also for patients who returned to dialysis. No gender or age differences could be found, with the exception of a higher cost of transplantation for children and a generally higher cost for younger compared with older patients on dialysis. A negative association was also found between age at the time of transplantation and the size of the cost savings for the younger part of the sample. Kidney transplantations have led to substantial cost savings for the Swedish health care system. An increase in donated kidneys has the potential to further reduce the cost of renal replacement therapy.

Antidote shortage is a global problem. In Thailand, the National Antidote Project (NAP) has operated since November 2010 to manage the national antidote stockpile, educate the healthcare providers on appropriate antidote use, and evaluate antidote usage. To evaluate the effect of NAP implementation on mortality rate and antidote use in cyanide poisoning cases arising from ingestion of cyanide or cyanogenic glycoside. This is a retrospective cohort of poisoning cases involving cyanide or cyanogenic glycoside ingestion reported to Ramathibodi Poison Center from 1 January 2007 to 31 December 2015. Mortality rate, antidote use, and appropriateness of antidote use (defined as correct indication, proper dosing regimen, and administration within 90 min) before and after NAP implementation were compared. Association between parameters and fatal outcomes was analyzed. A total of 343 cases involving cyanide or cyanogenic glycoside ingestion were reported to Ramathibodi Poison Center. There were 213 cases (62.1%) during NAP (Project group) and 130 cases (37.9%) pre-NAP implementation (Before group). Implementation of NAP led to increased antidote use (39.9% in Project group versus 24.6% in Before group) and a higher rate of appropriate antidote use (74.1% in Project group versus 50.0% in Before group). All 30 deaths were presented with initial severe symptoms. Cyanide chemical source and self-harm intent were associated with death (OR: 12.919, 95% CI: 4.863-39.761 and OR: 10.747, 95% CI: 3.884-28.514, respectively). No difference in overall mortality rate (13 [10.0%] deaths before versus 17 [8.0%] deaths after NAP) was found. In subgroup analysis of 80 cases with initial severe symptoms, NAP and appropriate antidote use reduced mortality (OR: 0.327, 95% CI: 0.106-0.997 and OR: 0.024, 95% CI: 0.004-0.122, respectively). In the multivariate analysis of the cases with initial severe symptoms, presence of the NAP and appropriate antidote use independently reduced the risk of

Full Text Available BackgroundIn Nepal tuberculosis, outdoor and indoor air pollution, cigarette smoking, smoking during pregnancy, poor working and health conditions in industries are common. Perceptions about various aspects of lung health among non-medical personnel working in medical schools in Nepal have not been previously studied. Method The study was carried out during January 2009. Basic demographic information was collected. Participants’ perceptions about various aspects of lung health were studied by noting their agreement with a set of 50 statements using a modified Likert-type scale. The median total score and scores of various subcategories were calculated. The scores were compared among various subgroups of respondents using appropriate non-parametric tests. After noting the deficiencies a structured interactive session to correct them was conducted. Participant perceptions were studied immediately after the session using the same questionnaire and the scores compared to those before the session.ResultsFifty-one respondents completed the questionnaire before the education session and 31 did so post-session. The majority of respondents were female, less than 40 years of age, either Brahmins or Chhetris, belonged to middle socioeconomic group; high school educated and used gas at home for cooking. The median total score was 182 before the session and increased to 218 post-session (maximum possible score 250. There was a significant increase in the scores of different subcategories also. ConclusionNon-medical personnel in a Nepalese medical school had good knowledge and understanding of various aspects of lung health which further improved following an educational session.

Cardiovascular magnetic resonance (CMR) has become the examination of choice in case of suspicion of acute myocarditis. Late gadolinium enhancement (LGE) imaging is very important to establish this diagnosis. Cine MRI sequences are useful for the study of the myocardial contractility.   The purpose is to estimate the value of cine MRI sequences before and after injection for the diagnosis of acute myocarditis compared with late gadolinium enhanced sequences. We prospectively included 40 patients having a high suspicion of acute myocarditis and examined using a 1.5 Tesla CMR. Cine MRI sequences before and after injection were performed. The protocol also include  T2-weighted  short- tau-inversion-recovery (STIR T2) fast spin echo MRI and LGE imaging eight minutes after injection with visual adjustment of inversion time. Delayed enhancement was found among 23 patients. Fifteen patients (65 %) presented a spontaneous hyper signal detected visually on Cine MRI sequences before injection and 11 patients (48 %) on STIR T2. The hyper signal on Cine MRI sequences after injection of gadolinium was the same topography that the late raising at 23 patients. In addition, we highlighted a significant difference between this hyper signal before injection and the left ventricle ejection fraction (p=0.022) as well as with the telesystolic volume of the left ventricle (LV) indexed by the body mass (p=0.039). Our study suggests that Cine MRI sequences after injection are of equal performance in the diagnosis of acute myocarditis as the LGE sequences and its contibution is important when we want to shorten the examination or when inversion time isn't optimal.

Highlights: • 4D CTA showed excellent agreement with DSA with regard to identification of feeding arteries and drainage veins. • The most important finding was 4D CTA in determining the impact of DAVF treatment with transarterial embolization. • 4D CTA provides images similar to those obtained with DSA both before and after treatment. - Abstract: Purpose: This study aimed to evaluate the usefulness of four-dimensional CTA before and after embolization treatment with ONYX-18 in eleven patients with cranial dural arteriovenous fistulas, and to compare the results with those of the reference standard DSA. Patients and Methods: Eleven patients with cranial dural arteriovenous fistulas detected on DSA underwent transarterial embolization with ONYX-18. Four-dimensional CTA was performed an average of 2 days before and 4 days after DSA. Four-dimensional CTA and DSA images were reviewed by two neuroradiologists for identification of feeding arteries and drainage veins and for determining treatment effects. Interobserver and intermodality agreement between four-dimensional CTA and DSA were assessed. Results: Forty-two feeding arteries were identified for 14 fistulas in the 11 patients. Of these, 36 (85.71%) were detected on four-dimensional CTA. After transarterial embolization, one patient got partly embolized, and the fistulas in the remaining 10 patients were completely occluded. The interobserver agreement for four-dimensional CTA and intermodality agreement between four-dimensional CTA and DSA were excellent (κ = 1) for shunt location, identification of drainage veins, and fistula occlusion after treatment. Conclusion: Four-dimensional CTA images are highly accurate when compared with DSA images both before and after transarterial embolization treatment. Four-dimensional CTA can be used for diagnosis as well as follow-up of cranial dural arteriovenous fistulas in clinical settings

A Jupiter-family comet, 17P/Holmes, underwent outbursts in 1892 and 2007. In particular, the 2007 outburst is known as the greatest outburst over the past century. However, little is known about the activity before the outburst because it was unpredicted. In addition, the time evolution of the nuclear physical status has not been systematically studied. Here, we study the activity of 17P/Holmes before and after the 2007 outburst through optical and mid-infrared observations. We found that the nucleus was highly depleted in its near-surface icy component before the outburst but that it became activated after the 2007 outburst. Assuming a conventional 1 μm sized grain model, we derived a surface fractional active area of 0.58% ± 0.14% before the outburst whereas the area was enlarged by a factor of ∼50 after the 2007 outburst. We also found that large (≥1 mm) particles could be dominant in the dust tail observed around aphelion. Based on the size of the particles, the dust production rate was ≳170 kg s{sup –1} at a heliocentric distance of r{sub h} = 4.1 AU, suggesting that the nucleus was still active around the aphelion passage. The nucleus color was similar to that of the dust particles and average for a Jupiter-family comet but different from that of most Kuiper Belt objects, implying that color may be inherent to icy bodies in the solar system. On the basis of these results, we concluded that more than 76 m of surface material was blown off by the 2007 outburst.

An intrauterine device (IUD) is one of the most frequently used methods of birth control around the world. Although a relationship between its use and menstrual disorders has been well documented, only a few studies have tried to show whether there are any vascular modifications. The aim of our study was to evaluate the influence of an IUD on uterine artery blood flow using Doppler assessment. A total of 100 patients selected for IUD use were prospectively evaluated with Doppler analysis before and 30 days after insertion. The resistive index (RI) and pulsatility index (PI) were used to evaluate uterine artery vascular resistance. Patients were allocated in 2 groups according to whether they were (group 2) or were not (group 1) lactating. The PI and RI of the patients in groups 1 and 2 before and after IUD insertion were not statistically significantly different (P = .298 and .23). When we compared uterine artery blood flow indices before and after IUD insertion for groups 1 and 2 separately, we observed in group 1 that the mean +/- SD PI values were 2.45 +/- 0.62 and 2.55 +/- 0.55 (P = .38) and the RI values were 0.87 +/- 0.08 and 0.87 +/- 0.06 (P = .88) before and after IUD insertion, respectively. In group 2, the PI values were 2.31 +/- 0.55 and 2.37 +/- 0.69 (P = .68) and the RI values were 0.85 +/- 0.07 and 0.86 +/- 0.07 (P = .44) before and after IUD insertion. Finally, we used the mean blood flow indices of the uterine arteries of all patients to compare the effect of IUD insertion. Results were also not statistically significant when we compared PI and RI before and after IUD insertion. The presence of an IUD does not interfere with the vascular resistance of the uterine arteries that can be shown by Doppler flow assessments 1 month after insertion.

To evaluate survival curves (Kaplan-Meier) as a means of identifying areas in the clinical pathway amenable to quality improvement. Observational before-after study. In Norway, annual public reporting of nationwide 30-day in-and-out-of-hospital mortality (30D) for three medical conditions started in 2011: first time acute myocardial infarction (AMI), stroke and hip fracture; reported for 2009. 12 of 61 hospitals had statistically significant lower/higher mortality compared with the hospital mean. Three hospitals with significantly higher mortality requested detailed analyses for quality improvement purposes: Telemark Hospital Trust Skien (AMI and stroke), Østfold Hospital Trust Fredrikstad (stroke), Innlandet Hospital Trust Gjøvik (hip fracture). Survival curves, crude and risk-adjusted 30D before (2008-2009) and after (2012-2013). Unadjusted survival curves for the outlier hospitals were compared to curves based on pooled data from the other hospitals for the 30-day period 2008-2009. For patients admitted with AMI (Skien), stroke (Fredrikstad) and hip fracture (Gjøvik), the curves suggested increased mortality from the initial part of the clinical pathway. For stroke (Skien), increased mortality appeared after about 8 days. The curve profiles were thought to reflect suboptimal care in various phases in the clinical pathway. This informed improvement efforts. For 2008-2009, hospital-specific curves differed from other hospitals: borderline significant for AMI (p=0.064), highly significant (p≤0.005) for the remainder. After intervention, no difference was found (p>0.188). Before-after comparison of the curves within each hospital revealed a significant change for Fredrikstad (p=0.006). For the three hospitals, crude 30D declined and they were non-outliers for risk-adjusted 30D for 2013. Survival curves as a supplement to 30D may be useful for identifying suboptimal care in the clinical pathway, and thus informing design of quality improvement projects

Objectives This study aimed to test the extensor carpi radialis and cranial tibial reflexes in cats before and after anesthetic block of the brachial and lumbosacral plexus, respectively, to determine whether they depend on a myotatic reflex arc. Methods Fifty-five cats with a normal neurologic examination that were referred for elective gonadectomy were divided into group 1 (29 cats) for testing the extensor carpi radialis reflex, and group 2 (26 cats) for testing the cranial tibial reflex. In group 1, the extensor carpi radialis reflex was tested after anesthetic induction and 15 mins after brachial plexus block with lidocaine. In group 2, the cranial tibial, withdrawal and patellar reflexes were elicited in 52 hindlimbs and retested 15 mins after epidural anesthesia. Results In group 1, before the anesthetic block, 55.17% of the cats had a decreased and 44.83% had a normal extensor carpi radialis reflex. After the block, 68.96% showed a decreased and 27.59% a normal reflex. No cat had an increased or absent reflex before anesthetic block. In group 2, prior to the anesthetic block, 15.38% of the cats had a decreased cranial tibial reflex and 84.62% had a normal response, whereas after the block it was decreased in 26.92% and normal in 73.08% of the cats. None of the cats had an increased or absent reflex. Regarding the presence of both reflexes before and after anesthetic block, there was no significant difference at 1% ( P = 0.013). Conclusions and relevance The extensor carpi radialis and cranial tibial reflexes in cats are not strictly myotatic reflexes, as they are independent of the reflex arc, and may be idiomuscular responses. Therefore, they are not reliable for neurologic examination in this species.

The body composition of 30 elderly (22 females: 78,2+7,6; 8 males: 80,4+5,4 yrs) and 38 middle-aged (27 females: 45,5+10.3; 11 males: 42,3+8,7 yrs) people suffering of essential hypertension determined by complex clinical and biological examinations (BP: 160-180/100-200 Hgmm), was determined before and after treatment. Most of them (78%) could be reassessed after 3 month of treatment (beta-blocking drugs or diuretics). The authors also investigated a few numbers (n=10) of patients presenting a hypertensive crisis treated with vasodilatant drugs and diuretics during 1 week of period. The hormonal status of all of them was assessed at the same time. The body composition was determined by multiple-isotope method

The therapeutic effect of pneumatic dilatation was evaluated quantitatively by radionuclide transit study in 11 achalasia patients. Before pneumatic dilatation, marked retention with more than 80 % of isotope in the esophagus at 15 minutes after ingestion was noted in all patients. Marked improvement in emptying was shown after pneumatic dilatation. Pneumatic dilatation is a safe and effective therapeutic aid for achalasia treatment, and radionuclide transit study is not only noninvasive and physiologic but also its procedure is easily performed. We conclude that radionuclide transit study is a good method to evaluate the result of the treatment quantitatively in achalasia patients.

Regional radiotherapy (RT) is increasingly used in breast cancer treatment. Conventionally, computed tomography (CT) is performed for RT planning. Lymph node (LN) target levels are delineated according to anatomical boundaries. Magnetic resonance imaging (MRI) could enable individual LN delineation. The purpose was to evaluate the applicability of MRI for LN detection in supine treatment position, before and after sentinel-node biopsy (SNB). Twenty-three female breast cancer patients (cTis-3N0M0) underwent 1.5 T MRI, before and after SNB, in addition to CT. Endurance for MRI was monitored. Axillary levels were delineated. LNs were identified and delineated on MRI from before and after SNB, and on CT, and compared by Wilcoxon signed-rank tests. LN locations and LN-based volumes were related to axillary delineations and associated volumes. Although postoperative effects were visible, LN numbers on postoperative MRI (median 26 LNs) were highly reproducible compared to preoperative MRI when adding excised sentinel nodes, and higher than on CT (median 11, p  <  0.001). LN-based volumes were considerably smaller than respective axillary levels. Supine MRI of LNs is feasible and reproducible before and after SNB. This may lead to more accurate RT target definition compared to CT, with potentially lower toxicity. With the MRI techniques described here, initiation of novel MRI-guided RT strategies aiming at individual LNs could be possible.

Indications and treatment results of ureteric calculi one year before and one year after the introduction of ESWL were analysed in 169 consecutive patients. Sex, age, former stone operation, stone localisation and stone size were not significantly different in the two groups. Before ESW1 47...... with ESWL, but not significantly. Judged from the length of the hospital stay there was no major economic benefit from ESWL. In conclusion, ESWL with a second generation lithotriptor is suitable for in situ treatment of ureteric calculi. It should be first choice for ureteric calculi....

Image-based computational models with fluid-structure interaction (FSI) can be used to perform plaque mechanical analysis in intracranial artery stenosis. We described a process in FSI study applied to symptomatic severe intracranial (M1) stenosis before and after stenting. Reconstructed 3D angiography in STL format was transferred to Magics for smoothing of vessel surface and trimming of branch vessels and to HyperMesh for generating tetra volume mesh from triangular surface-meshed 3D angiogram. Computational analysis of blood flow in the blood vessels was performed using the commercial finite element software ADINA Ver 8.5. The distribution of wall shear stress (WSS), peak velocity and pressure was analyzed before and after intracranial stenting. The wall shear stress distributions from Computational fluid dynamics (CFD) simulation with rigid wall assumption as well as FSI simulation before and after stenting could be compared. The difference of WSS between rigid wall and compliant wall model both in pre- and post-stent case is only minor except at the stenosis region. These WSS values were greatly reduced after stenting to 15~20 Pa at systole and 3~5 Pa at end-diastole in CFD simulation, which are similar in FSI simulations. Our study revealed that FSI simulation before and after intracranial stenting was feasible despite of limited vessel wall dimension and could reveal change of WSS as well as flow velocity and wall pressure.

Common mental health disorders like depressive and anxiety disorders are frequent in antenatal and postpartum women. However, no agreement about the prevalence of these disorders and the course of women's mental health during the transition to motherhood exists. This study compared women's mental health before, during, and after pregnancy with a control group of nonpregnant women. Three hundred and twenty-four women were assessed before, during, and after their pregnancy with the 12-item version of the General Health Questionnaire (GHQ-12). A control group of 324 women who did not deliver during 3 subsequent years was assessed with the GHQ-12 at corresponding time-points. No differences in GHQ-12 mean scores, prevalence, and incidence of common mental health disorders between the study and control groups were found. No differences in prevalence and incidence rates within each group were found. The presence of a common mental health disorder before pregnancy or in early pregnancy predicted common mental health disorders in the postpartum period. Common mental health disorders are frequent during pregnancy and the postpartum period, but pregnant or postpartum women are not more at risk than those who are not pregnant or who did not deliver.

Abortion Before & After Roe

2013-01-01

We use unique data on abortions performed in New York State from 1971–1975 to demonstrate that women travelled hundreds of miles for a legal abortion before Roe. A100- mile increase in distance for women who live approximately 183 miles from New York was associated with a decline in abortion rates of 12.2 percent whereas the same change for women who lived 830 miles from New York lowered abortion rates by 3.3 percent. The abortion rates of nonwhites were more sensitive to distance than those of whites. We found a positive and robust association between distance to the nearest abortion provider and teen birth rates but less consistent estimates for other ages. Our results suggest that even if some states lost all abortion providers due to legislative policies, the impact on population measures of birth and abortion rates would be small as most women would travel to states with abortion services.

Study Design Descriptive, prospective single-cohort longitudinal study. Background Though rapid torque development is essential in activities of daily living and sports, it hasn't been specifically tested by most physical therapists or incorporated into rehabilitation programs until late in the treatment process. Little evidence is available on quadriceps torque development capacity before and after arthroscopic knee surgery. Objectives To study knee extensor rate of torque development, contributing mechanisms, and associations with strength and patient-reported outcomes before and during the first 6 weeks after arthroscopic partial meniscectomy. Methods Twenty subjects (mean ± SD age, 42.3 ± 13.7 years; body mass index, 26.6 ± 3.1 kg/m 2 ) were tested before surgery, and at 2 and 5 weeks after surgery. Quadriceps muscle volume, strength, activation, rate of torque development, and patient-reported outcomes were evaluated across the study period. Results Significant side-to-side differences in quadriceps strength and voluntary rate of torque development were observed at each time point (Ptorque development capacity. Side-to-side rate of torque development deficits after surgery were associated with lower patient-reported outcomes scores. Conclusion Diminished rapid torque development capacity is common in arthroscopic meniscal debridement patients. This reduced capacity is associated with an inability to quickly recruit and drive the quadriceps muscles (neural mechanisms) and not muscle atrophy or other peripheral factors tested. Patient-reported outcomes are associated with quadriceps rate of torque development, but not strength or muscle size. Rapid torque development warrants greater attention in rehabilitation.

To provide the objective basis for the evaluation of the operative results of vascularized greater trochanter bone flap in treating osteonecrosis of the femoral head (ONFH) by three-dimensional gait analysis. Between March 2006 and March 2007, 35 patients with ONFH were treated with vascularized greater trochanter bone flap, and gait analysis was made by using three-dimensional gait analysis system before operation and at 1, 2 years after operation. There were 23 males and 12 females, aged 21-52 years (mean, 35.2 years), including 8 cases of steroid-induced, 7 cases of traumatic, 6 cases of alcoholic, and 14 cases of idiopathic ONFH. The left side was involved in 15 cases, and right side in 20 cases. According to Association Research Circulation Osseous (ARCO) classification, all patients were diagnosed as having femoral-head necrosis at stage III. Preoperative Harris hip functional score (HHS) was 56.2 +/- 5.6. The disease duration was 1.5-18.6 years (mean, 5.2 years). All incisions healed at stage I without early postoperative complications of deep vein thrombosis and infections of incision. Thirty-five patients were followed up 2-3 years with an average of 2.5 years. At 2 years after operation, the HHS score was 85.8 +/- 4.1, showing significant difference when compared with the preoperative score (t = 23.200, P = 0.000). Before operation, patients showed a hip muscles gait, short gait, reduce pain gait, and the pathological gaits significantly improved at 1 year after operation. At 1 year and 2 years after operation, step frequency, pace, step length and hip flexion, hip extension, knee flexion, ankle flexion were significantly improved (P petronas wave appeared at swing phase; the preoperative situation was three normal phase waves. These results suggest that three-dimensional gait analysis before and after vascularized greater trochanter for ONFH can evaluate precisely hip vitodynamics variation.

Purpose: To find the audiological outcome after LINAC-based fractionated stereotactic irradiation (STI). Materials and methods: Twenty-four patients with vestibular schwannoma treated by fractionated STI between 1991 and 1997 had measurable hearing before STI and were followed audiologically for more than 6 months. The pure tone average (PTA) was measured by averaging the air-conduction threshold for five main frequencies (250-4000 Hz) before and periodically after STI in the 24 patients. Several possible prognostic factors for hearing preservation (defined as a PTA change at the last follow-up of less than 10 dB) were investigated. The median follow-up time was 22 months, ranging from 5 to 69 months. The irradiation schedule was 36 Gy in 20 fractions in 5 weeks to 44 Gy in 22 fractions in 6 weeks followed by 4 Gy/1 fraction boost. Results: The pure tone average before STI was distributed from 7 to 73 dB. Fifty percent of patients showed a change in PTA of less than 10 dB, 79.2% of patients showed a change in PTA of less than 20 dB and 20.8% of patients showed a change in PTA of more than 21 dB at the last follow-up. Only one patient (4%) became deaf. Cases with a sudden loss of hearing were more likely to experience hearing preservation than those with gradual loss of hearing (P<0.05). The mean age was younger in patients whose hearing was preserved (P<0.05). Poor pretreatment PTA appeared to linearly correspond to the changes in PTA (regression coefficient 0.78). The size of the tumor was not related to the change in PTA. No relationship was observed between the maximum or peripheral dose and the PTA change. The real benefit of stereotactic boost after small-field fractionated irradiation was not certain. Conclusion: Fractionated STI produced a hearing preservation rate compatible with meticulously collimated multi-spots single fraction irradiation. Further follow-up is required to confirm the long-term benefits of fractionation. (Copyright (c) 1998 Elsevier

High-dose melphalan has been the standard conditioning regimen for auto-SCT in multiple myeloma (MM) for decades. A more effective conditioning regimen may induce deeper responses and longer remission duration. It is especially needed in the setting of second auto-SCT, which rarely achieves comparable results with the first auto-SCT using the same conditioning regimen. Here we conducted a phase II study to investigate the efficacy and safety of a conditioning regimen V-BEAM (bortezomib-BEAM) before second auto-SCT for multiple myeloma. Ten patients were enrolled from September 2012 to May 2013. The CR rate at day +100 after auto-SCT was 75%; all except for one patient remained in remission after a median follow-up of 6 months. Three patients developed Clostridium difficile infection. Two patients died within the first 30 days of auto-SCT from neutropenic colitis and overwhelming sepsis, respectively. Due to the high rate of morbidity and mortality, the study was terminated after 10 patients. In summary, although the conditioning regimen V-BEAM before second auto-SCT for MM provided promising responses, it was associated with unexpected treatment-related toxicity and should not be investigated further without modifications.

Background Little is known about the hemodynamic response to exercise in heart failure patients at various ages before and after heart transplantation (HT). This information is important because postoperative hemodynamics may be a predictor of survival. To investigate the hemodynamic response to HT and exercise, we grouped our patients based on preoperative age and examined their hemodynamics at rest and during exercise before and after HT. Methods and Results Ninety-four patients were evaluated at rest prior to HT with right heart catheterization at our laboratory. Of these patients, 32 were evaluated during slight supine exercise before and 1 year after HT. Postoperative evaluations were performed at rest 1 week after HT and at rest and during exercise at 4 weeks, 3 months, 6 months, and 1 year after HT. The exercise patients were divided into 2 groups based on preoperative age of ≤50 or >50 years. There were no age-dependent differences in the preoperative hemodynamic exercise responses. Hemodynamics markedly improved at rest and during exercise at 1 and 4 weeks, respectively, after HT; however, pulmonary and, in particular, ventricular filling pressures remained high during exercise at 1 year after HT, resulting in normalized pulmonary vascular resistance response but deranged total pulmonary vascular resistance response. Conclusions Our findings suggest that, (1) in patients with heart failure age ≤50 or >50 years may not affect the hemodynamic response to exercise to the same extent as in healthy persons, and (2) total pulmonary vascular resistance may be more adequate than pulmonary vascular resistance for evaluating the exercise response after HT.

Similar levels of polychlorinated biphenyls (PCBs), pesticides, and fat were found in 20 correlated uncooked and cooked (baked) bluefish fillets. Fillets averaged 2.5 ppm PCBs as Aroclor 1254 (whole basis) before cooking; after cooking, with the oil drippings and skin discarded, the average PCB level was 2.7 ppm. Although PCBs, lipophilic pesticides, and fat were lost along with oil drippings and skin that were discarded after cooking, the moisture loss in the fillets during cooking compensated for these weight losses almost completely. After the fillets were cooked and the oil drippings and skin were discarded, the PCB content of the fillets was 27% lower on the average.

Neural underpinnings of emotion dysregulation in borderline personality disorder (BPD) are characterized by limbic hyperactivity and disturbed prefrontal activity. It is unknown whether neural correlates of emotion regulation change after a psychotherapy which has the goal to improve emotion dysregulation in BPD, such as dialectical behavioral therapy (DBT). We investigated distraction as a main emotion regulation strategy before and after DBT in female patients with BPD. Thirty-one BPD patients were instructed to either passively view or memorize letters before being confronted with negative or neutral pictures in a distraction task during functional magnetic resonance imaging. This paradigm was applied before and after a 12-week residential DBT-based treatment program. We compared the DBT group to 15 BPD control patients, who continued their usual, non-DBT-based treatment or did not have any treatment, and 22 healthy participants. Behaviorally, BPD groups and healthy participants did not differ significantly with respect to alterations over time. On the neural level, BPD patients who received DBT-based treatment showed an activity decrease in the right inferior parietal lobe/supramarginal gyrus during distraction from negative rather than neutral stimuli when compared to both control groups. This decrease was correlated with improvement in self-reported borderline symptom severity. DBT responders exhibited decreased right perigenual anterior cingulate activity when viewing negative (rather than neutral) pictures. In conclusion, our findings reveal changes in neural activity associated with distraction during emotion processing after DBT in patients with BPD. These changes point to lower emotional susceptibility during distraction after BPD symptom improvement.

In this study, serum adiponectin level was evaluated in 35 primary breast cancer patients and 10 healthy females, before and after treatment to assess if there is a relation between it and breast cancer, and to find out if it has a prognostic value. Serum adiponectin level was significantly lower in all and postmenopausal breast cancer patients before taking any type of treatment, and non-significantly lower in locally advanced breast cancer patients after treatment by 4 cycles of neoadjuvant chemotherapy than healthy controls. Non-significant elevations was shown after treatment by surgery, and also after completing treatment by surgery followed by taking 2 cycles of adjuvant chemotherapy followed by treatment by radiotherapy in case of premenopausal locally advanced breast cancer patients. Triglycerides showed significantly higher level in all groups of patients. There was statistical negative correlation between serum adiponectin level and body mass index (BMI) in postmenopausal healthy controls, and between serum adiponectin level and BMI, triglycerides in all and postmenopausal breast cancer patients before taking any type of treatment. In conclusion, this study suggests that low serum adiponectin level is likely to be associated with increased breast cancer risk, particularly among postmenopausal women. The association between obesity and breast cancer risk might be partly explained by adiponectin

Full Text Available Abstract Background Presumptive treatment of all febrile patients with anti-malarials leads to massive over-treatment. The aim was to assess the effect of implementing malaria rapid diagnostic tests (mRDTs on prescription of anti-malarials in urban Tanzania. Methods The design was a prospective collection of routine statistics from ledger books and cross-sectional surveys before and after intervention in randomly selected health facilities (HF in Dar es Salaam, Tanzania. The participants were all clinicians and their patients in the above health facilities. The intervention consisted of training and introduction of mRDTs in all three hospitals and in six HF. Three HF without mRDTs were selected as matched controls. The use of routine mRDT and treatment upon result was advised for all patients complaining of fever, including children under five years of age. The main outcome measures were: (1 anti-malarial consumption recorded from routine statistics in ledger books of all HF before and after intervention; (2 anti-malarial prescription recorded during observed consultations in cross-sectional surveys conducted in all HF before and 18 months after mRDT implementation. Results Based on routine statistics, the amount of artemether-lumefantrine blisters used post-intervention was reduced by 68% (95%CI 57-80 in intervention and 32% (9-54 in control HF. For quinine vials, the reduction was 63% (54-72 in intervention and an increase of 2.49 times (1.62-3.35 in control HF. Before-and-after cross-sectional surveys showed a similar decrease from 75% to 20% in the proportion of patients receiving anti-malarial treatment (Risk ratio 0.23, 95%CI 0.20-0.26. The cluster randomized analysis showed a considerable difference of anti-malarial prescription between intervention HF (22% and control HF (60% (Risk ratio 0.30, 95%CI 0.14-0.70. Adherence to test result was excellent since only 7% of negative patients received an anti-malarial. However, antibiotic

The results of clinical, X-ray, and biochemical studies carried out in 51 patients with uremic osterodystrophy, treated with hemodialysis, before and after parathyroidectomy are presented. The patients were divided into 4 groups with various patterns of X-ray symptoms. Analysis of the clinical and X-ray data before and after parathyroidectomy has brought to a conclusion that such an intervention was effective only in cases with manifest clinical and X-ray symptoms of fibrous osteodystrophy. Surgical treatment is containdicated to patients in whom X-ray signs of osteomalacia predominate over fibrous osteodystrophy; it may result in a rap[id progress of osteomalacia

This study aimed to evaluate the usefulness of four-dimensional CTA before and after embolization treatment with ONYX-18 in eleven patients with cranial dural arteriovenous fistulas, and to compare the results with those of the reference standard DSA. Eleven patients with cranial dural arteriovenous fistulas detected on DSA underwent transarterial embolization with ONYX-18. Four-dimensional CTA was performed an average of 2 days before and 4 days after DSA. Four-dimensional CTA and DSA images were reviewed by two neuroradiologists for identification of feeding arteries and drainage veins and for determining treatment effects. Interobserver and intermodality agreement between four-dimensional CTA and DSA were assessed. Forty-two feeding arteries were identified for 14 fistulas in the 11 patients. Of these, 36 (85.71%) were detected on four-dimensional CTA. After transarterial embolization, one patient got partly embolized, and the fistulas in the remaining 10 patients were completely occluded. The interobserver agreement for four-dimensional CTA and intermodality agreement between four-dimensional CTA and DSA were excellent (κ=1) for shunt location, identification of drainage veins, and fistula occlusion after treatment. Four-dimensional CTA images are highly accurate when compared with DSA images both before and after transarterial embolization treatment. Four-dimensional CTA can be used for diagnosis as well as follow-up of cranial dural arteriovenous fistulas in clinical settings. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

The purpose of this study was to evaluate the effects of psychosocial factors on pain levels and depression, before and after surgical treatment, in patients with degenerative lumbar and cervical vertebral disc disease. The study included 188 patients (98 women, 90 men) who were confirmed to have cervical or lumbar degenerative disc disease on magnetic resonance imaging, and who underwent a single microdiscectomy procedure, with no postoperative surgical complications. All patients completed two questionnaires before and after surgery - the Beck Depression Inventory scale (I-IV) and the Visual Analog Scale for pain (0-10). On hospital admission, all patients completed a social and demographic questionnaire. The first pain and depression questionnaire evaluations were performed on the day of hospital admission (n=188); the second on the day of hospital discharge, 7 days after surgery (n=188); and the third was 6 months after surgery (n=140). Patient ages ranged from 22 to 72 years, and 140 patients had lumbar disc disease (mean age, 42.7±10.99 years) and 44 had cervical disc disease (mean age, 48.9±7.85 years). Before surgery, symptoms of depression were present in 47.3% of the patients (11.7% cervical; 35.6% lumbar), at first postoperative evaluation in 25.1% of patients (7% cervical; 18.1% lumbar), and 6 months following surgery in 31.1% of patients (7.5% cervical; 23.6% lumbar). Patients with cervical disc disease who were unemployed had the highest incidence of depression before and after surgery ( p =0.037). Patients with lumbar disc disease who had a primary level of education or work involving standing had the highest incidence of depression before and after surgery ( p =0.368). This study highlighted the association between social and demographic factors, pain perception, and depression that may persist despite surgical treatment for degenerative vertebral disc disease.

This paper presents results obtained from ambient vibration and strong-motion responses of a thirteen-story, moment-resisting steel framed Santa Clara County Office Building (SCCOB) before being retrofitted by visco-elastic dampers and from ambient vibration response following the retrofit. Understanding the cumulative structural and site characteristics that affect the response of SCCOB before and after the retrofit is important in assessing earthquake hazards to other similar buildings and decision making in retrofitting them. The results emphasize the need to better evaluate structural and site characteristics in developing earthquake resisting designs that avoid resonating effects. Various studies of the strong-motion response records from the SCCOB during the 24 April 1984 (MHE) Morgan Hill (MS = 6.1), the 31 March 1986 (MLE) Mt. Lewis (MS = 6.1) and the 17 October 1989 (LPE) Loma Prieta (MS = 7.1) earthquakes show that the dynamic characteristics of the building are such that it (a) resonated (b) responded with a beating effect due to close-coupling of its translational and torsional frequencies, and (c) had a long-duration response due to low-damping. During each of these earthquakes, there was considerable contents damage and the occupants felt the rigorous vibration of the building. Ambient tests of SCCOB performed following LPE showed that both translational and torsional periods of the building are smaller than those derived from strong motions. Ambient tests performed following the retrofit of the building with visco-elastic dampers show that the structural fundamental mode frequency of the building has increased. The increased frequency implies a stiffer structure. Strong-motion response of the building during future earthquakes will ultimately validate the effectiveness of the retrofit method.This paper presents results obtained from ambient vibration and strong-motion responses of a thirteen-story, moment-resisting steel framed Santa Clara County

Research interventions in uniform clinical settings and in patients fulfilling well-defined inclusion criteria might show a more pronounced effect than implementing the same intervention in existing practice. Diabetes Self-Management Education (DSME) is complex, and should be assessed in existing practice as it is an intervention widely implemented. To examine the impact of an established group-based DSME in unselected people with type 2 diabetes referred from primary care. A one-group, before-after design was used for assessments before, immediately after, and 3 months after participation in a group-based DSME programme conducted at two Learning and Mastering Centres in Norway between November 2013 and June 2014. Participants completed a questionnaire before (n = 115), immediately after (n = 95) and 3 months after (n = 42) the DSME programme. Primary outcome measure was diabetes knowledge (Michigan Diabetes Knowledge Test). Also patient activation (Patient Activation Measure [PAM]) and self-efficacy (General Self-Efficacy scale [GSE]) were measured. Changes in outcome measures were analysed using paired t-tests for normally distributed data and Wilcoxon signed-rank test for skewed data. Mean knowledge improved significantly from baseline (p < 0.001). Changes persisted at the 3-month assessment. Mean PAM scores improved significantly from baseline (p < 0.001), and changes persisted for 3 months. Mean GSE scores improved from baseline (p = 0.022) and persisted for 3 months. However, when results were stratified for participants who responded at all three time points, GSE showed no change during the study period. The complexity self-management in the individual is challenging to reflect in DSME. This implemented DSME programme for people with type 2 diabetes improved levels of diabetes knowledge and patient activation, persisting for at least 3 months. Hence, the DSME programme appears to be robust beyond standardised research settings, in educating unselected

Our study was done to assess the cytological changes due to oncotherapy in breast carcinoma especially on morphometry and proliferative activity. Cytological aspirates were collected from a total of 32 cases of invasive ductal carcinoma both before and after oncotherapy. Morphometry was done on the stained cytological smears to assess the different morphological parameters of cell dimension by using the ocular morphometer and the software AutoCAD 2007. Staining was done with Ki-67 and proliferating cell nuclear antigen (PCNA) as proliferative markers. Different morphological parameters were compared before and after oncotherapy by unpaired Student's t test. Statistically significant differences were found in morphometric parameters, e.g., mean nuclear diameter, mean nuclear area, mean cell diameter, and mean cell area, and in the expression of proliferative markers (Ki-67 and PCNA). Statistical analysis was done by obtaining p values. There are statistically significant differences between morphological parameter of breast carcinoma cells before and after oncotherapy.

There is evidence suggesting that autoimmune Addison's disease (AD) could be associated with sexual dysfunctions probably caused by gluco- and mineralocorticoid deficiency; however, no study has yet treated this subject in males. To evaluate male sexuality and psychological correlates in autoimmune AD before and after gluco- and mineralocorticoid replacement therapy. Twelve subjects with a first diagnosis of autoimmune AD were studied before (baseline) and 2 months after (recovery phase) initiating hormone replacement therapy. Erectile function (EF), orgasmic function (OF), sexual desire (SD), intercourse satisfaction (IS), overall satisfaction (OS), depression, and anxiety were studied using a number of questionnaires (International Index of Erectile Function, Beck Depression Inventory, and Spielberger State-Trait Anxiety Inventory); clinical, biochemical, and hormone data were included in the analysis. At baseline, low values were found for EF, OF, SD, IS, and OS and high values for depression and anxiety; all of these parameters improved significantly in the recovery phase compared with baseline. EF variation between the two phases correlated significantly and positively with the variation of serum cortisol, urinary free cortisol, systolic blood pressure, and diastolic blood pressure and inversely with that of upright plasma renin activity. Multiple linear regression analysis using EF variation as dependent variable confirmed the relationship of the latter with variation of serum cortisol, urinary free cortisol, and upright plasma renin activity but not with variation of systolic and diastolic blood pressure. Our study showed that onset of autoimmune AD in males is associated with a number of sexual dysfunctions, all reversible after initiating replacement hormone therapy; cortisol and aldosterone deficiency seems to play an important role in the genesis of erectile dysfunction although the mechanism of their activity is not clear. © 2012 International Society

Full Text Available Traffic engineering uses engineering methods and techniques to achieve the safe and time efficient movement of people and goods on roadways and it depends on traffic flow. The three main parameters of a traffic flow are volume, speed and density. Speed is an important transportation consideration because it relates to safety, time, comfort, convenience, and economics. This study is to show the difference of traffic speed for before, during and after a primary traffic survey called “Banci Lalu Lintas”. This study also is conducted at Federal Road FT005 with collaboration of Jabatan Kerja Raya (JKR. In achieving the goal for this study, traffic speed is recorded by using two methods which are manual method and Automatic Traffic Count (ATC. For before and after the survey, manual method is used and the data is collected for 15 minutes, while during the survey, ATC is used in collecting data for 24 hours per day in a week. The data obtained where the mean speed is recorded and is compared as well as analyzed between three categories which are before, during and after “Banci Lalu Lintas” and using statistical analysis. In result, the speed of vehicles for during the survey is the lowest compared to before and after survey where the differential percentage are 6.68% and 23.64% for before – during and during – after “Banci Lalu Lintas”. The study concluded that drivers tend to decrease their vehicles speed when there is an event or unexpected conditions on the road. The result is important for future development and safety of road in Malaysia.

Reported planning before and after quitting and quit success: retrospective data from the ITC 4-Country Survey.

Planning before quitting smoking is widely believed to be beneficial and is usually recommended in cessation counseling, but there is little evidence on the efficacy of specific planning activities. Using data from 1140 respondents who reported quit attempts at Wave 8 of the ITC 4-Country Survey, we analyzed use of 8 specific planning strategies before (5) and after (3) implementation of a quit attempt, in relation to cessation outcomes, delay in implementation of the attempt, and recent quitting history. Most participants reported some planning both before and after quitting, even among those reporting quitting 'spontaneously.' Younger smokers, those who cut down before quitting, and users of stop-smoking medication were more likely to report planning. Those who planned prequit were also more likely to plan postquit. Unexpectedly, we found no clear benefit of planning on short-term (1 month) cessation outcomes, whereas one prequit strategy (practicing not smoking) was negatively related to outcome. There was evidence for a predicted moderating effect of recent quitting experience on planning for the prequit task 'practice replacement strategies.' This predicted quit success among those with multiple quit attempts in the past year, but failure among those without. This finding suggests that the quality of planning may be critical. More research, particularly on the moderating effect of quit experience, and where measures of planning are collected before outcomes become evident, is needed before clear recommendations can be made on the utility of various forms of planning for the success of quit attempts.
