Full Text Available Introduction: Voice disorders are a well-known complication which is often associated with thyroid gland diseases and because voice is still the basic mean of communication it is very important to maintain its quality healthy. Objectives: The aim of this study referred to questions whether there is a statistically significant difference between results of voice self-assessment, perceptual voice assessment and acoustic voice analysis before and after thyroidectomy and whether there are statistically significant correlations between variables of voice self-assessment, perceptual assessment and acoustic analysis before and after thyroidectomy. Methods: This scientific research included 12 participants aged between 41 and 76. Voice self-assessment was conducted with the help of Croatian version of Voice Handicap Index (VHI. Recorded reading samples were used for perceptual assessment and later evaluated by two clinical speech and language therapists. Recorded samples of phonation were used for acoustic analysis which was conducted with the help of acoustic program Praat. All of the data was processed through descriptive statistics and nonparametric statistical methods. Results: Results showed that there are statistically significant differences between results of voice self-assessments and results of acoustic analysis before and after thyroidectomy. Statistically significant correlations were found between variables of perceptual assessment and acoustic analysis. Conclusion: Obtained results indicate the importance of multidimensional, preoperative and postoperative assessment. This kind of assessment allows the clinician to describe all of the voice features and provides appropriate recommendation for further rehabilitation to the patient in order to optimize voice outcomes.

A stress reaction involving increased adrenal hormone release occurs when starting adrenal venous sampling (AVS). The purpose of the present study was to investigate the effect of single shot venography on adrenal hormone production during AVS. This was a prospective self-controlled study. We enrolled 54 consecutive patients (21 men, 33 women; mean age 52 ± 11 years) with primary aldosteronism who underwent AVS from May 2014 to February 2015. Under non-stimulated conditions, blood samples were obtained from a common trunk of the left adrenal vein before and after single shot venography. The initial plasma aldosterone and cortisol concentration (PAC and PCC) were compared with those measured after venography for each patient. PAC and PCC were slightly but significantly decreased between before and after venography (after log transformation 2.12 ± 0.73 vs 2.07 ± 0.72, P = 0.00066, 1.89 ± 0.52 vs 1.83 ± 0.53, P = 0.00031, respectively). During non-stimulated left AVS, adrenal hormone secretion was slightly but significantly decreased after venography, similar to the normal time-related stress reaction. Venography did not increase the adrenal hormone secretion.

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.

In developing countries, youngsters start to work during the high school years. Several studies have shown the difficulties associated with double shift, i.e. to work and study concomitantly, and its negative health consequences. Work and study time, as social synchronizers, have significant effects on the sleep-wake cycle (SWC). The purpose of this study was to evaluate sleep patterns and sleepiness in young students before and after entering the workforce as apprentices or trainees. Participants were 40 adolescents (26 males), 15-18 years old (mean = 15.8 years old) engaged in a first-job program at a non-governmental organization (NGO) while attending evening high school in the outskirts of the city of São Paulo, Brazil. The participants wore actigraphs (Ambulatory Monitoring, Inc.) and registered subjective sleepiness on KSS (Karolinska Sleepiness Scale) along 7 consecutive days, before and after admission to the job. Descriptive analyses were performed, and the variables were tested by means of the t-test and repeated measures ANOVA taking factors day of the week and time of the day into consideration. The participants' sleep duration on weekdays exhibited significant difference before and after starting work (F = 4.55; p = 0.04); the mean sleep duration was 492 min (SD = 44 min) before admission to the job to decrease to 405 min (SD = 58 min) after starting work. The mid-sleep time exhibited significant difference on weekdays before and after starting work (04:57 h; SD = 45 min versus 03:30 h; SD = 54 min; F = 4.91; p = 0.03). Finally, also sleepiness on weekdays (F = 6.41; p = 0.04) and at the waking time (F = 10.75; p sleep restriction. Brazilian governmental incentives notwithstanding, simultaneous performance of several activities by young workers should be considered as an occupational health hazard. Employment policies targeting young workers should take the dual shift - study and work

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.

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.

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.

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.

Happiness: before and after the kids.

Understanding how having children influences parents' subjective well-being ("happiness") has great potential to explain fertility behavior. We study parental happiness trajectories before and after the birth of a child, using large British and German longitudinal data sets. We account for unobserved parental characteristics using fixed-effects models and study how sociodemographic factors modify the parental happiness trajectories. Consistent with existing work, we find that happiness increases in the years around the birth of a first child and then decreases to before-child levels. Moreover, happiness increases before birth, suggesting that the trajectories may capture not only the effect of the birth but also the broader process of childbearing, which may include partnership formation and quality. Sociodemographic factors strongly modify this pattern. Those who have children at older ages or who have more education have a particularly positive happiness response to a first birth; and although having the first two children increases happiness, having a third child does not. The results, which are similar in Britain and Germany, suggest that having up to two children increases happiness, and mostly for those who have postponed childbearing. This pattern is consistent with the fertility behavior that emerged during the second demographic transition and provides new insights into low and late fertility.

Assess the impact of routine injection of 5 units of oxytocin as soon as the anterior shoulder is delivered on the incidence of postpartum haemorrhage (PPH) in a context of daily practice. Single-centre before-and-after study evaluating the effect of a change in the protocol for PPH prevention as applied in our obstetrical unit. During the first period, oxytocin (5 units) was to be injected only in case of PPH risk factors. During the second period, the injection was systematic. In the "before" study period, there were 1953 patients vaginal deliveries and 843 (43%) oxytocin injections, with a protocol compliance of 85%. In the "after" study period, 2018 women had vaginal deliveries and 1911 (95%) had an oxytocin injection (protocol compliance: 95%). The whole study period was associated with a reduced risk of moderate haemorrhage (13.4% vs. 9.2%, Phaemorrhage was observed (2.1% vs. 2.0%, P=0.79). After logistic regression, the study period remained associated with a significant reduction in the risk of moderate PPH (OR=0.72 [0.58-0.89]). Routine injection of 5 units of oxytocin makes it possible to reduce the risk of moderate PPH, but it does not affect the risk of severe PPH. Copyright © 2015 Elsevier Masson SAS.

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.

Several barriers to the adoption of electronic medical records (EMRs) by family physicians have been discussed, including the costs of implementation, impact on work flow and loss of productivity. We examined billings and payments received before and after implementation of EMRs among primary care physicians in the province of Ontario. We also examined billings and payments before and after switching from a fee-for-service to a capitation payment model, because EMR implementation coincided with primary care reform in the province. We used information from the Electronic Medical Record Administrative Data Linked Database (EMRALD) to conduct a retrospective before-after study. The EMRALD database includes EMR data extracted from 183 community-based family physicians in Ontario. We included EMRALD physicians who were eligible to bill the Ontario Health Insurance Plan at least 18 months before and after the date they started using EMRs and had completed a full 18-month period before Mar. 31, 2011, when the study stopped. The main outcome measures were physicians' monthly billings and payments for office visits and total annual payments received from all government sources. Two index dates were examined: the date physicians started using EMRs and were in a stable payment model (n = 64) and the date physicians switched from a fee-for-service to a capitation payment model (n = 42). Monthly billings and payments for office visits did not decrease after the implementation of EMRs. The overall weighted mean annual payment from all government sources increased by 27.7% after the start of EMRs among EMRALD physicians; an increase was also observed among all other primary care physicians in Ontario, but it was not as great (14.4%). There was a decline in monthly billings and payments for office visits after physicians changed payment models, but an increase in their overall annual government payments. Implementation of EMRs by primary care physicians did not result in decreased

Full Text Available Background Vitiligo is an acquired disease in which the loss of functional melanocytes results in depigmented macules and patches. Over the years, wide arrays of markers for melanocytes have been described, including human melanoma black 45 (HMB-45. Narrow-band ultraviolet B (NB-UVB therapy is one of the therapeutic modalities for vitiligo. Objectives We sought to detect HMB-45 staining after 30 sessions of NB-UVB therapy in vitiligo and perivitiliginous skin. Patients and Methods All the participants were planned to have 30 sessions of NB-UVB therapy with 724 lamps (FS, 72 T, 12-HO Daavlin MED at 311 nm wavelengths. The patients underwent skin sampling from lesional and perilesional area before and after 30 sessions of treatment. The skin biopsies were sent to the laboratory for light microscopy and immunohistochemical study. The evaluation of HMB-45 was based on the quantitative method, measuring the number of positive stained cells. Clinical response was defined as repigmentation in three categories: more than 75%; between 40% and 75%; and less than 40%. The data were analyzed using SPSS (version 17. Results Twenty-nine patients completed the study. The Wilcoxon test showed a meaningful relation between HMB-45 staining before and after NB-UVB treatment in perilesional skin. We did not find a meaningful relation between HMB-45 staining before and after treatment regarding the mean age, gender, mean duration of disease, and initial lesional area (P = 0.55, P = 0.41, P = 0.55, and P = 0.87, respectively. After 30 sessions of NB-UVB therapy, repigmentation was less than 40% in 8 (27.6%, 40 - 75% in 7 (24.1%, and more than 75% in 6 patients. Conclusions The HMB-45 stain strength significantly changed after treatment in perilesional skin.

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.

Full Text Available Abstract Background Antihypertensive drug choices and treatment levels are not in accordance with the existing guidelines. We aimed to assess the impact of a guideline implementation intervention on antihypertensive drug prescribing. Methods In this controlled before and after study, the effects of a multifaceted (education, audit and feedback, local care pathway quality programme was evaluated. The intervention was carried out in a health centre between 2002 and 2003. From each health care unit (n = 31, a doctor-nurse pair was trained to act as peer facilitators in the intervention. All antihypertensive drugs prescribed by 25 facilitator general practitioners (intervention GPs and 53 control GPs were retrieved from the nationwide Prescription Register for three-month periods in 2001 and 2003. The proportions of patients receiving specific antihypertensive drugs and multiple antihypertensive drugs were measured before and after the intervention for three subgroups of hypertension patients: hypertension only, with coronary heart disease, and with diabetes. Results In all subgroups, the use of multiple concurrent medications increased. For intervention patients with hypertension only, the odds ratio (OR was 1.12 (95% CI 0.99, 1.25; p = 0.06 and for controls 1.13 (1.05, 1.21; p = 0.002. We observed no statistically significant differences in the change in the prescribing of specific antihypertensive agents between the intervention and control groups. The use of agents acting on the renin-angiotensin-aldosterone system increased in all subgroups (hypertension only intervention patients OR 1.19 (1.06, 1.34; p = 0.004 and controls OR 1.24 (1.15, 1.34; p Conclusions A multifaceted guideline implementation intervention does not necessarily lead to significant changes in prescribing performance. Rigorous planning of the interventions and quality projects and their evaluation are essential.

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.

Objective: To study the effect of vasopressin (VS) on the small-bowel circulation and the safety of embolotherapy for the small intestinal hemorrhage by DSA. Methods: Ten dogs were divided into three groups. Vasa recta were ligated 30 min after VS infusion ended in group A (n = 4), and 2h after VS infusion ended in group B (n = 4), they were ligated without VS infusion in control group (n = 2). DSA were performed before and after VS infusion, before and after the ligation. The tested parts of intestine were resected to make the pathologic examination a week late. Results: All branches of mesenteric arteries contracted and the contrast developed light in the intestinal wall after VS infusion. Branches contraction recovered but the contrast developed still slight in the intestinal wall about 30 min after infusion ended. All manifestation of DSA recovered to normal 2h after infusion ended. In all groups, the blood vessel net can be seen but is fewer and scattered in the area of ligation. The collocate presented soon after the ligation. The pathologic examination proved that there was only mind mucosal ischemia in all groups. Conclusion: The repressive effect of VS to the circulation of intestine weakened and then disappeared rapidly after the infusion ended. VS infusion had no significant effect on the safety of embolotherapy for small intestinal bleeding when the infusion has been finished for more than 2hr. DSA can demonstrated the circulation state of the intestine before and after embolization

Background Hyperthyroidism has been linked with different morbidities, like atrial fibrillation, stroke and diabetes mellitus. However, our knowledge regarding the extent and temporal relation between hyperthyroidism and other diseases is fragmented. Here, we aimed at evaluating various morbidities before and after the diagnosis of hyperthyroidism. Methods Observational cohort study. From nationwide Danish health registers 2631 hyperthyroid singletons and 375 twin pairs discordant for hyperthyroidism were identified and followed for an average of 6 years (range 0–13). Data on the occurrence of cardiovascular diseases, lung diseases, diabetes mellitus, rheumatic diseases and malignant diseases was obtained by person-to-person record linkage with the National Danish Patient Register and/or the Danish National Prescription Registry (lung diseases and diabetes mellitus). Logistic and Cox regression models were used to assess the risk of morbidity before and after the diagnosis of hyperthyroidism, respectively. All Cox regression analyses were adjusted for the degree of co-morbidity preceding the diagnosis of hyperthyroidism, using the Charlson score. Results Hyperthyroid individuals had a significantly higher risk of being diagnosed with cardiovascular diseases (odds ratio (OR) 1.65; 95% confidence interval (CI): 1.45–1.87), lung diseases (OR 1.53; 95% CI: 1.29–1.60), and diabetes mellitus (OR 1.43, 95% CI: 1.20–1.72), but not with malignant diseases (OR 1.16, 95% CI: 0.99–1.36) prior to the diagnosis of hyperthyroidism. After the diagnosis of hyperthyroidism, subjects had a significantly higher risk of being diagnosed with cardiovascular diseases (hazard ratio (HR) 1.34; 95% CI: 1.15–1.56), lung diseases (HR 1.28; 95% CI: 1.10–1.49), and diabetes mellitus (HR 1.46; 95% CI: 1.16–1.84), but not with rheumatic diseases (HR 1.39, 95% CI: 0.92–2.09) or malignant diseases (HR 1.18, 95% CI 0.97–1.42). Conclusions We demonstrate a significantly increased

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

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.

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

The aging of zirconia ceramics (Y-TZP) is associated with tetragonal to monoclinic phase transformation. This change in microstructure may affect the optical properties of the ceramic. This study examines the effect of aging on the translucency of different zirconia materials. 120 disc-shaped specimens were fabricated from four zirconia materials: Cercon ht white, BruxZir Solid Zirconia, Zenostar T0, Lava Plus (n = 30 per group). Accelerated aging was performed in a steam autoclave (134°C, 0.2 MPa, 5 hours). CIELab coordinates (L*, a*, b*) and luminous reflectance (Y) were measured with a spectrophotometer before and after aging. Contrast ratio (CR) and translucency parameter (TP) were calculated from the L*, a*, b*, and Y tristimulus values. The general linear model (Bonferroni adjusted) was used to compare both parameters before and after aging, as well as between the different zirconia materials (p ≤ 0.05). CR and TP differed significantly before and after aging in all groups tested. Before aging, Zenostar T showed the highest and Lava Plus showed the lowest translucency. After aging, Cercon ht and Zenostar T showed the highest and BruxZir and Lava Plus the lowest translucency. Aging reduced the translucency in all specimens tested. Furthermore, translucency differed between the zirconia brands tested. Nevertheless, the differences were below the detectability threshold of the human eye. The aging process can influence the translucency and thus the esthetic outcome of zirconia restorations; however, the changes in translucency were minimal and probably undetectable by the human eye. © 2018 by the American College of Prosthodontists.

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.

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

1986-11-01

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.

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.

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.

The aim of this study was to explore antiepileptic drug (AED) prescribing before, during and after pregnancy as recorded in seven population-based electronic healthcare databases. Databases in Denmark, Norway, the Netherlands, Italy (Emilia Romagna/Tuscany), Wales and the Clinical Practice Research Datalink, representing the rest of the UK, were accessed for the study. Women with a pregnancy starting and ending between 2004 and 2010, which ended in a delivery, were identified. AED prescriptions issued (UK) or dispensed (non-UK) at any time during pregnancy and the 6 months before and after pregnancy were identified in each of the databases. AED prescribing patterns were analysed, and the choice of AEDs and co-prescribing of folic acid were evaluated. In total, 978 957 women with 1 248 713 deliveries were identified. In all regions, AED prescribing declined during pregnancy and was lowest during the third trimester, before returning to pre-pregnancy levels by 6 months following delivery. For all deliveries, the prevalence of AED prescribing during pregnancy was 51 per 10 000 pregnancies (CI95 49-52%) and was lowest in the Netherlands (43/10 000; CI95 33-54%) and highest in Wales (60/10 000; CI95 54-66%). In Denmark, Norway and the two UK databases lamotrigine was the most commonly prescribed AED; whereas in the Italian and Dutch databases, carbamazepine, valproate and phenobarbital were most frequently prescribed. Few women prescribed with AEDs in the 3 months before pregnancy were co-prescribed with high-dose folic acid: ranging from 1.0% (CI95 0.3-1.8%) in Emilia Romagna to 33.5% (CI95 28.7-38.4%) in Wales. The country's differences in prescribing patterns may suggest different use, knowledge or interpretation of the scientific evidence base. The low co-prescribing of folic acid indicates that more needs to be done to better inform clinicians and women of childbearing age taking AEDs about the need to offer and receive complete preconception care

Single photon emission computed tomography with N-isopropyl-p-[I-123]iodoamphetamine was performed in 13 cases of craniosynostosis before and after surgery. Of 13 cases, 8 cases (62%) showed focal low perfusion area on preoperative study. Four of seven cases (57%) with brachycephaly showed low perfusion areas in either of frontal lobes, occipital lobes, and cerebellum. Besides, two patients with scaphocephaly and one with plagiocephaly showed low perfusion area in the unilateral cerebral hemisphere. Two Crouzon disease cases showed no focal low perfusion area, but an Apert disease showed low perfusion areas in both frontal lobes, cerebellum, as well as left occipital lobe. Corresponding CT and MRI showed no focal abnormality in any of these cases. These low perfusion areas were diminished or disappeared after surgical treatment in 6 cases (75%). We conclude that the I-123-IMP-SPECT is considered to be a useful index for the evaluation of functional recovery after surgery in cases of craniosynostosis. (author)

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 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....

The effect of marijuana on human health has been studied extensively. Marijuana intoxication has been shown to affect performance, attention span, and reaction time. The public health relationship between trauma and cannabis use has also been studied, with mixed conclusions. In this report, the effect of marijuana legalization on many aspects of facial trauma at two hospitals in Denver, Colorado is examined. A retrospective review of the electronic medical records was undertaken. Mann-Whitney U tests were used to compare age of patients before and after legalization, and chi squared analyses were used to compare mechanism of injury, and fracture types before and after recreational marijuana legalization in Denver, Colorado. Geographical location of patients was also considered. No significant increase was found in race before and after marijuana legalization (p=0.19). A significant increase in age was found before (M=39.54,SD=16.37), and after (M=41.38,SD=16.66) legalization (p0.05). Public health efforts should be directed towards educating residents and visitors of Colorado on the effects and toxicology of marijuana. More epidemiologic studies are needed for further assessment of the long-term effects of the legalization of marijuana on the population. Copyright © 2017 Elsevier Inc. All rights reserved.

2014-01-01

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

Vocal Nodules (VN) are a functional voice disorder associated with voice misuse and abuse in children. There are few reports addressing vocal parameters in children with VN, especially after a period of vocal rehabilitation. The purpose of this study is to describe measurements of vocal parameters including Fundamental Frequency (FF), Shimmer (S), and Jitter (J), videonasolaryngoscopy examination and clinical perceptual assessment, before and after voice therapy in children with VN. Voice therapy was provided using visual support through Speech-Viewer software. Twenty patients with VN were studied. An acoustical analysis of voice was performed and compared with data from subjects from a control group matched by age and gender. Also, clinical perceptual assessment of voice and videonasolaryngoscopy were performed to all patients with VN. After a period of voice therapy, provided with visual support using Speech Viewer-III (SV-III-IBM) software, new acoustical analyses, perceptual assessments and videonasolaryngoscopies were performed. Before the onset of voice therapy, there was a significant difference (ptherapy period, a significant improvement (pvocal nodules were no longer discernible on the vocal folds in any of the cases. SV-III software seems to be a safe and reliable method for providing voice therapy in children with VN. Acoustic voice parameters, perceptual data and videonasolaryngoscopy were significantly improved after the speech therapy period was completed. Copyright © 2012 Elsevier Ireland Ltd.

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.

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 study levels of sick leave and disability pension before and after TNF-antagonist therapy in AS patients. Using the population-based South Swedish Arthritis Treatment Group register, we identified 139 AS patients (aged 18-58 years, 78% men), who between January 2002 and December 2008 started their first treatment with adalimumab, etanercept or infliximab. We linked data to the payment register by the Swedish Social Insurance Agency and calculated the proportion on sick leave in 30-day intervals from 12 months before treatment start until 12 months after. For each AS patient, we randomly selected four subjects from the general population matched for age, sex and area of residence. One to 3 months before treatment, an average of 24% of AS patients were on sick leave. During the first 6 months after treatment start, this fraction dropped to 15%, and further declined to 12% at 12 months (P patients with the general population, the relative risk of being on sick leave 3 months before treatment, treatment start and 12 months after treatment start was 8.0 (95% CI 4.6, 13.9), 9.2 (95% CI 5.4, 15.7) and 4.0 (95% CI 2.1, 6.3), respectively. The decrease in sick leave was not substantially offset by changes in disability pension. There is a decline in sick leave during the first 12 months after initiation of TNF-antagonist treatment in AS patients not explained by societal factors or secular trends. The proportion of AS patients on disability pension remained unchanged during the observation period.

Full Text Available In uncontrolled before-after studies, CONSORT was shown to improve the reporting of randomised trials. Before-after studies ignore underlying secular trends and may overestimate the impact of interventions. Our aim was to assess the impact of the 2007 STROBE statement publication on the quality of observational study reporting, using both uncontrolled before-after analyses and interrupted time series.For this quasi-experimental study, original articles reporting cohort, case-control, and cross-sectional studies published between 2004 and 2010 in the four dermatological journals having the highest 5-year impact factors (≥ 4 were selected. We compared the proportions of STROBE items (STROBE score adequately reported in each article during three periods, two pre STROBE period (2004-2005 and 2006-2007 and one post STROBE period (2008-2010. Segmented regression analysis of interrupted time series was also performed.Of the 456 included articles, 187 (41% reported cohort studies, 166 (36.4% cross-sectional studies, and 103 (22.6% case-control studies. The median STROBE score was 57% (range, 18%-98%. Before-after analysis evidenced significant STROBE score increases between the two pre-STROBE periods and between the earliest pre-STROBE period and the post-STROBE period (median score2004-05 48% versus median score2008-10 58%, p<0.001 but not between the immediate pre-STROBE period and the post-STROBE period (median score2006-07 58% versus median score2008-10 58%, p = 0.42. In the pre STROBE period, the six-monthly mean STROBE score increased significantly, by 1.19% per six-month period (absolute increase 95%CI, 0.26% to 2.11%, p = 0.016. By segmented analysis, no significant changes in STROBE score trends occurred (-0.40%; 95%CI, -2.20 to 1.41; p = 0.64 in the post STROBE statement publication.The quality of reports increased over time but was not affected by STROBE. Our findings raise concerns about the relevance of uncontrolled before-after

Thyroid hormones are necessary for fetal brain development, and hypothyroidism in adults has been associated with mood symptoms and reduced quality of life. Nevertheless, our knowledge regarding the association and temporal relation between hypothyroidism and mental disorders is ambiguous. Our objective was to investigate, at a nationwide level, whether a diagnosis of hypothyroidism is associated with psychiatric morbidity. This is an observational cohort study. On the basis of record linkage between different Danish health registers, 2822 hypothyroid singletons each matched with 4 nonhypothyroid controls were identified and followed over a mean period of 6 years (range 1-13). Additionally, we included 385 same-sex twin pairs discordant for hypothyroidism. Diagnoses of psychiatric disorders as well as treatment with antidepressants, antipsychotics, and anxiolytics were recorded. Logistic and cox regression models were used to assess the risk of psychiatric morbidity before and after the diagnosis of hypothyroidism, respectively. Before the diagnosis of hypothyroidism, such individuals had an increased prevalence of diagnoses with psychiatric disorders (odds ratio, OR, 1.51; 95% confidence interval [CI 1.12-2.04]) and increased prevalence of treatment with antipsychotics (OR 1.49 [CI 1.29-1.73]), antidepressants (OR 1.50 [CI 1.35-1.67]), and anxiolytics (OR 1.28 [CI 1.16-1.41]). After the diagnosis of hypothyroidism, patients had a higher risk of being diagnosed with a psychiatric disorder (hazard ratio, HR, 2.40 [CI 1.81-3.18]), and an increased risk of being treated with antidepressants (HR 1.30 [CI 1.15-1.47]) and anxiolytics (HR 1.27 [CI 1.10-1.47]), but not antipsychotics (HR 1.13 [CI 0.91-1.41]). On the basis of the twin data, we could not demonstrate genetic confounding. Subjects with hypothyroidism have an increased risk of being diagnosed with a psychiatric disorder as well as being treated with antidepressants, antipsychotics, and anxiolytics both before

Wortman, Jessica; Lucas, Richard E

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).

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

1992-11-15

We performed radionuclide ventriculography before and within 1 week after percutaneous mirtal valvuloplasty (PMV) to evaluate left ventricular (LV) function in 20 patients (2 meals and 17 females, mean age of 38 {+-} 10 years) who were pure mitral stenosis before PMV and less than grade 1 mirtal regurgitation developed after PMV. 9 out of 20 patients had atrial fibrillation and 3 patients developed a small left-to-right shunt (Qp/Qs < 1.5) after PMV. PMV using double-balloon technique resulted in a increase in mitral valve area (0.9 {+-} 0.3 to 2.1 {+-} 0.8cm{sup 2}, {rho} < 0.001) and in rest cardiac output (4.2 {+-} 1.0 to 4.8 {+-} 1.4 L/min, {rho} < 0.005). And also a decrease in mean mitral gradient (16.2 {+-} 7.0 to 5.2 {+-} 3.0 mmHg, {rho} < 0.001) was noted. Comparisons of LV function by supine bicycle exercise radionuclide ventriculography before and after PMV showed no significant changes in rest LV ejection fraction (LVEF, 55.2 {+-} 9.7 to 56.1 {+-} 11.0%, {rho} > 0.05), maximal exercise LVEF (60.9 {+-} 10.3 to 59.3 {+-} 11.1%, {rho} > 0.05), peak ejection rate (2.02 {+-} 0.58 to 2.15 {+-} 0.60 EDV/ses, {rho} > 0.05), and peak filling rate (1.04 {+-} 0.55 to 1.52 {+-} 0.49 EDV/ses, {rho} > 0.05). However, LV end diastolic volume (LVEDV, -29.3 {+-} 19.0 to +3.3 {+-} 32.9%, {rho} < 0.001), stroke volume (SV,-22.0 {+-} 22.0 to +11.2 {+-} 40.0%, {rho} < 0.001), and cardiac output (CO, 64.6 {+-} 54.0 to 100.4 {+-} 69.7%, {rho} < 0.05) with exercise compared to resting values were significantly increased. We conclude that PMV resulted in a significant increase in LVEDV, SV, and CO with exercise, but decreased LV systolic performance and no improvement in diastolic filling.

99m Tc-DMSA renal scintigraphy was carried out in 54 patients with unilateral renal stones before and after PNL. Four to 8 weeks after PNL the DMSA renal uptake significantly decreased to 17.2±6.0% from 18.2±6.7% before PNL. DMSA renal uptake did not change in the contralateral side. Since in some patients changes in the DMSA renal uptake of 5-7% were observed after PNL not only in the PNL side but also in the contralateral side, the renal function was assessed by the formula: DMSA renal uptake in the PNL side/DMSA renal uptake in the contralateral side, and the change of this ratio was evaluated in 44 patients, in whom the renal DMSA uptake in the PNL side was less than two times that in the contralateral side. The DMSA renal uptake ratio decreased to 95.6±8.7% from the base line 4-8 weeks after PNL. This change was statistically significant. Some functional risks such as massive bleeding with PNL, the fever after PNL and the number of nephrostomy tract did not affect the decrease in the renal function. In 29 patients in whom renal function was reevaluated one year after PNL, the DMSA renal uptake ratio significantly decreased to 94.2±9.6% from the base line 4-8 weeks after PNL. But the ratio significantly improved to 99.6±11.6% about one year after PNL. In two patients with a cold area on the renal image, the renal function of the operated side still remained at about 80% levels from the base line even one year after PNL. It is concluded that although renal function slightly decreased 4-8 weeks after PNL, it is expected to improve within one year after PNL. But in the case with a cold area on the renal image, the complete functional recovery would not be expected. 99m Tc-DMSA renal scintigraphy is a useful adjunct to evaluate the renal function before and after PNL.

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.

Electromyographic investigation of unstable patella before and after its realignment operation

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. 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.

Lung function studies before and after a work shift

Energy Technology Data Exchange (ETDEWEB)

Love, R G

1983-05-01

The lung function of 23 underground coal workers and eight surface workers at a Scottish colliery was measured immediately before and after a work shift. Changes in lung function were assessed in relation to the measured respirable dust exposure and the time of day in which the shift was worked. Large, and statistically significant, decrements of lung function during the shift were found in night-shift workers compared with workers on other shifts. Measurements derived from the forced expiratory manoeuvre, particularly FEV1, Vmax50, and Vmax25, after three vital capacity breaths of an 80% He/20% O2 mixture, showed large reductions in night-shift men, smaller reductions in afternoon-shift men, and small increases or decreases in morning-shift underground and surface workers. Within-shift changes for other tests, such as closing volume, N2 index, and volume of isoflow, did not differ significantly between shifts. No significant relationship was found between dust exposure and functional changes during a shift for any test. Lung function changes in a control group of 25 female workers not exposed to dust (hospital nurses) did not show the same large variations between day and night shifts. Examination of a further control group of 16 office workers did not show any difference in diurnal changes between smokers and non-smokers. It is concluded that these coal miners, even on permanent shift patterns, had widely different changes in their lung function cycle depending on which shift they were working. These changes did not appear to be related to dust exposure or cigarette smoking and were not consistent with other biological adaptations known to result from regular night-shift working.

Few population-based studies have assessed lipid adherence to international guidelines for primary and secondary prevention in stroke/transient ischaemic attack (TIA) patients. This study aims to evaluate adherence to lipid-lowering therapy (LLT) guidelines amongst patients with ischaemic stroke/TIA. Using hot and cold pursuit methods from multiple hospital/community sources, all stroke and TIA cases in North Dublin City were prospectively ascertained over a 1-year period. Adherence to National Cholesterol Education Programme (NCEP) III guidelines, before and after index ischaemic stroke/TIA, was assessed. Amongst 616 patients (428 ischaemic stroke, 188 TIA), total cholesterol was measured following the qualifying event in 76.5% (471/616) and low-density lipoprotein (LDL) in 60.1% (370/616). At initial stroke/TIA presentation, 54.1% (200/370) met NCEP III LDL goals. Compliance was associated with prior stroke (odds ratio [OR] 2.19, p = 0.02), diabetes (OR 1.91, p = 0.04), hypertension (OR 1.57, p = 0.03), atrial fibrillation (OR 1.78, p = 0.01), pre-event LLT (OR 2.85, p TIA onset, 32.7% (195/596) was on LLT. Nonetheless, LDL exceeded individual NCEP goal in 29.2% (56/192); 21.6% (53/245) warranting LLT was not on treatment prior to stroke/TIA onset. After index stroke/TIA, 75.9% (422/556) was on LLT; 15.3% (30/196) meeting NCEP III criteria was not prescribed a statin as recommended. By 2 years, actuarial survival was 72.8% and 11.9% (59/497) experienced stroke recurrence. No association was observed between initial post-event target adherence and 2-year outcomes. In this population-based study, LLT recommended by international guidelines was under-used, before and after index stroke/TIA. Strategies to improve adherence are needed.

2018-01-01

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.

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.

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.

2017-01-01

Full Text Available Aim: This study aims to evaluate the effect of saliva and blood contamination on the shear bond strength (SBS of self- and total-etch adhesive systems on enamel and dentin. Materials and Methods: Sample of 100 extracted noncarious primary molars were taken as experimental groups, which were divided into two groups: self-etch group and total-etch group containing fifty teeth each. These groups were further divided into five subgroups - 10 teeth each. The specimens were then subjected to contamination with saliva or blood; before and after application of adhesive agent, whereas, in control group, there was no contamination done before and after adhesive application. Fresh saliva and blood were used. After the bonding procedure, resin composite was built up with diameter and height of 3 mm. After that, the specimens were tested for SBS in universal testing machine at a crosshead speed of 1 cm/min. The results were then statistically analyzed using one-way ANOVA. Results: The results of the study revealed that the SBS of self-etch adhesive system was better than the total-etch adhesive system and there was significant difference found among various subgroups of total-etch group, i.e., when adhesive application was done before, after and without saliva or blood contamination. There was no significant difference found within the subgroups of self-etch group when adhesive application was done before, after, and without saliva contamination. In case of blood contamination, significant difference was found in SBS in both self- and total-etch groups.

Genital dissatisfaction is an important reason for transmen to undergo genital gender-confirming surgery (GCS; phalloplasty or metoidioplasty). However, little is known about motives for choosing specific techniques, how transmen benefit postoperatively, and whether psychosexual outcomes improve. To evaluate motivations for and psychosexual outcomes after GCS. A longitudinal study of 21 transmen at least 1 year after GCS was conducted. Participants were recruited through their surgeon. Data were collected when they applied for surgery and at least 1 year after surgery. Data collection included semistructured questionnaires on motivations for surgery, postoperative experiences, and standardized measures of psychological symptoms, body image, self-esteem, sexuality, and quality of life (pre- and postoperative). Information on surgical complications and corrections was retrieved from medical records. Most participants underwent phalloplasty with urethral lengthening using a radial forearm flap. Although problematic voiding symptoms were prevalent, many participants were satisfied with their penile function. The strongest motivations to pursue penile surgery were confirmation of one's identity (100%), enabling sexual intercourse (78%), and voiding while standing (74%). No significant differences between postoperative and reference values were observed for standardized measures. After surgery, transmen were more sexually active (masturbation and with a partner) and used their genitals more frequently during sex compared with before surgery (31-78%). The present study provides input for preoperative decision making: (i) main motives for surgery include identity confirmation, voiding, and sexuality, (ii) surgery can result in more sexual activity and genital involvement during sex, although some distress can remain, but (iii) complications and voiding symptoms are prevalent. Study strengths include its longitudinal design and the novelty of the studied outcomes. The main

To evaluate the effect of capecitabine and oxaliplatin before, during, and after radiotherapy for high-risk rectal cancer. Patients with rectum cancer T4 or T3 involving the mesorectal fascia was included in a prospective phase 2 trial. Liver or lung metastases were accepted if the surgeons found them resectable. The patients received 6 weeks of capecitabine and oxaliplatin before chemoradiotherapy (CRT), continued capecitabine and oxaliplatin during radiotherapy, and received 4 weeks of capecitabine and oxaliplatin after CRT. The patients received radiotherapy as intensity-modulated radiotherapy. Total mesorectal excision was planned 8 weeks after CRT. The patients were evaluated with magnetic resonance imaging (MRI) before start of treatment, after 6 weeks of chemotherapy, and again just before the operation. The European Organization for Research and Treatment of Cancer (EORTC) QLQ-CR29 scoring system was used to evaluate adverse events. Fifty-two patients were enrolled between 2009 and 2012. The treatment was well tolerated, with only one death during treatment. Eighty percent of assessable patients experienced response to chemotherapy alone as evaluated by MRI, which increased to 94% after complete oncologic treatment. Forty-nine patients had a total mesorectal excision performed, all with a R0 resection and with a pathologic complete response of 20% for patients with T3 tumor and 7% for patients with T4 tumor. Five patients had metastases at study entry, while 47 patients had locally advanced rectal cancer without metastases. Of these 47 patients, overall survival and progression-free survival at 5 years was 72% and 62%, respectively, with a median follow-up of 60 months. This aggressive approach with capecitabine and oxaliplatin before, during, and after radiotherapy for high-risk rectal cancer is safe and feasible; it also has an impressive response rate as measured by MRI and a promising 5-year overall survival.

2007-11-01

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

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

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.

2014-03-01

Pain catastrophizing has emerged as a significant risk factor for problematic recovery after musculoskeletal injury. As such, there has been an increased focus on interventions that target patients' levels of catastrophizing. However, it is not presently clear how clinicians might best interpret scores on catastrophizing before and after treatment. Thus, the purpose of this study was to provide preliminary guidelines for the clinical interpretation of scores on pain catastrophizing among individuals with subacute pain after musculoskeletal injury. A sample of 166 occupationally disabled individuals with subacute pain due to a whiplash injury participated in this study. Participants completed a 7-week standardized multidisciplinary rehabilitation program aimed at fostering functional recovery. Participants completed the Pain Catastrophizing Scale (PCS) upon program commencement and completion. One year later, participants indicated their pain severity and involvement in employment activities. Separate receiver operating characteristic curve analyses were conducted to determine absolute pretreatment and posttreatment and percent change scores on the PCS that were best associated with clinically important levels of pain and employment status at the follow-up. An absolute pretreatment PCS score of 24 best identified patients according to follow-up clinical outcomes. Posttreatment PCS scores of 14 and 15 best identified patients with high follow-up pain intensity ratings and those who did not return to work, respectively. PCS reductions of approximately 38% to 44% were best associated with return to work and low pain intensity ratings at follow-up. The results indicate scores on catastrophizing before and after treatment that are clinically meaningful. These results may serve as preliminary guidelines to assess the clinical significance of interventions targeting pain catastrophizing in patients with subacute pain after musculoskeletal injury.

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.

To explore utilisation patterns of asthma medication before, during and after pregnancy as recorded in seven European population-based databases. A descriptive drug utilisation study. 7 electronic healthcare databases in Denmark, Norway, the Netherlands, Italy (Emilia Romagna and Tuscany), Wales, and the Clinical Practice Research Datalink representing the rest of the UK. All women with a pregnancy ending in a delivery that started and ended between 2004 and 2010, who had been present in the database for the year before, throughout and the year following pregnancy. The percentage of deliveries where the woman received an asthma medicine prescription, based on prescriptions issued (UK) or dispensed (non-UK), during the year before, throughout or during the year following pregnancy. Asthma medicine prescribing patterns were described for 3-month time periods and the choice of asthma medicine and changes in prescribing over the study period were evaluated in each database. In total, 1,165,435 deliveries were identified. The prevalence of asthma medication prescribing during pregnancy was highest in the UK and Wales databases (9.4% (CI95 9.3% to 9.6%) and 9.4% (CI95 9.1% to 9.6%), respectively) and lowest in the Norwegian database (3.7% (CI95 3.7% to 3.8%)). In the year before pregnancy, the prevalence of asthma medication prescribing remained constant in all regions. Prescribing levels peaked during the second trimester of pregnancy and were at their lowest during the 3-month period following delivery. A decline was observed, in all regions except the UK, in the prescribing of long-acting β-2-agonists during pregnancy. During the 7-year study period, there were only small changes in prescribing patterns. Differences were found in the prevalence of prescribing of asthma medications during and surrounding pregnancy in Europe. Inhaled β-2 agonists and inhaled corticosteroids were, however, the most popular therapeutic regimens in all databases. Published by the BMJ

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.

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.)

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.

Full Text Available PURPOSE: This study examined the relationship between the near dissociated phoria and disparity vergence eye movements. Convergence insufficiency (CI patients before vergence therapy were compared to: 1 the same patients after vergence therapy and 2 binocularly normal controls (BNC. METHODS: Sixteen subjects were studied--twelve BNC and four with CI. Measurements from the CI subjects were obtained before and after 18 hours of vergence eye movement therapy. The near dissociated phoria was measured using the flashed Maddox rod technique. Vergence responses were stimulated from 4° symmetrical disparity vergence step stimuli. The peak velocity of the vergence response and the magnitude of the fusion initiating component (FIC from an independent component analysis were calculated. A linear regression analysis was conducted studying the vergence peak velocity as a function of the near dissociated phoria where the Pearson correlation coefficient was computed. RESULTS: Before vergence therapy, the average with one standard deviation FIC magnitude of convergence responses from CI subjects was 0.290.82 and significantly less than the FIC magnitude of 1.850.84 for BNC (p<0.02. A paired t-test reported that the FIC and near dissociated phoria before vergence therapy for CI subjects significantly increased to 1.490.57 (p<0.04 and became less exophoric to 3.5∆1.9 exo (p<0.02 after vergence therapy. A significant correlation (r=0.87; p<0.01 was observed between the near dissociated phoria and the vergence ratio of convergence peak velocity divided by divergence peak velocity. CONCLUSION: The results have clinical translational impact in understanding the mechanism by which vergence therapy may be changing the vergence system leading to a sustained reduction in visual symptoms.

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.

The pathogenesis of idiopathic osteonecrosis of the femoral head (ION) is thought to be an ischemic event. The purpose of this study is to investigate alterations of the blood pool in the femoral head before and after renal transplantation. After renal transplantation, all patients received the same immunosuppressive therapy: corticosteroids, cyclosporin-A, and azathioprine. We performed 3-phase bone scintigraphy on 16 renal allograft recipients within 1 week before renal transplantation, and between week 4 and 9 after renal transplantation. Regions of interest (ROI) were assigned bilaterally in the femoral head, diaphysis, and soft tissue. The head-to-diaphysis ratios (HD ratios) were then calculated. Idiopathic osteonecrosis of the femoral head occurred in 2 femoral heads of 1 patient. The HD ratio before renal transplantation (mean HD±SD, 1.52±0.30) and the HD ratio after renal transplantation (1.28±0.30) were significantly different (P=0.000024). The HD ratios before and after renal transplantation were significantly different, indicating that the administration of steroids diminished the blood pool in the femoral head. A low HD ratio before renal transplantation revealed a poor blood pool in the femoral head, which may be a risk factor for ION. (author)

To study the effect of antitubercular treatment (ATT) on the laparoscopic abdominopelvic and fallopian tube findings in female genital tuberculosis (FGBT). Prospective cohort (Canadian Task Force classification II2). Tertiary referral center in northern India. Fifty women with infertility and diagnosed with FGTB on laparoscopy, histopathology findings, or endometrial sampling (acid-fast bacilli culture, granuloma on histopathology, positive polymerase chain reaction). Diagnostic laparoscopy in all women diagnosed with FGTB before and after a 6-month course of ATT (2 months of rifampicin, isoniazid, pyrazinamide, and ethambutol, followed by 4 months of rifampicin and isoniazid). All procedures were performed by the same surgeon between June 2012 and May 2014. The mean patient age was 28.7 years, mean parity was 0.9, and mean body mass index was 23.6 kg/m(2). Infertility was seen in all 50 women (66% primary infertility, 34% secondary infertility), with a mean duration of 6.06 years. Abnormal laparoscopic findings of FGTB included tubercles in the pelvic peritoneum, fallopian tube, and ovary in 27 women (54%) before ATT and in only 1 (2.04%) woman after ATT (p women (8%) before ATT, and in no women after ATT (p right side (56%), left side (50%), and both sides (38%) before ATT. Hydrosalpinx, beaded tubes, and nonvisualized tube were seen in 33.4%, 4.1%, and 20.8% cases, respectively, after ATT; however, free spill increased to 52% on the right side and 50% on left side after ATT. ATT improves laparoscopic findings in FGTB with infertility. However, advanced fibrotic lesions (eg, pelvic and perihepatic adhesions, bilateral blocked tubes) do not improve with ATT.

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.

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.

Brake response time before and after total knee arthroplasty: a prospective cohort study

2010-11-01

Full Text Available Abstract Background Although the numbers of total knee arthroplasty (TKA are increasing, there is only a small number of studies investigating driving safety after TKA. The parameter 'Brake Response Time (BRT' is one of the most important criteria for driving safety and was therefore chosen for investigation. The present study was conducted to test the hypotheses that patients with right- or left-sided TKA show a significant increase in BRT from pre-operative (pre-op, 1 day before surgery to post-operative (post-op, 2 weeks post surgery, and a significant decrease in BRT from post-op to the follow-up investigation (FU, 8 weeks post surgery. Additionally, it was hypothesized that the BRT of patients after TKA is significantly higher than that of healthy controls. Methods 31 of 70 consecutive patients (mean age 65.7 +/- 10.2 years receiving TKA were tested for their BRT pre-op, post-op and at FU. BRT was assessed using a custom-made driving simulator. We used normative BRT data from 31 healthy controls for comparison. Results There were no significant increases between pre-op and post-op BRT values for patients who had undergone left- or right-sided TKA. Even the proportion of patients above a BRT threshold of 700 ms was not significantly increased postop. Controls had a BRT which was significantly better than the BRT of patients with right- or left-sided TKA at all three time points. Conclusion The present study showed a small and insignificant postoperative increase in the BRT of patients who had undergone right- or left-sided TKA. Therefore, we believe it is not justified to impair the patient's quality of social and occupational life post-surgery by imposing restrictions on driving motor vehicles beyond an interval of two weeks after surgery.

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.

Past studies utilizing resting-state functional MRI (rsfMRI), have shown that obese humans exhibit altered activity in brain areas related to reward compared to normal-weight controls. However, to what extent bariatric surgery-induced weight loss alters resting-state brain activity in obese humans is less well-studied. Thus, we measured the fractional amplitude of low-frequency fluctuations from eyes-closed, rsfMRI in obese females (n = 11, mean age = 42 years, mean BMI = 41 kg/m 2 ) in both a pre- and postprandial state at two time points: four weeks before, and four weeks after bariatric surgery. Several brain areas showed altered resting-state activity following bariatric surgery, including the putamen, insula, cingulate, thalamus and frontal regions. Activity augmented by surgery was also dependent on prandial state. For example, in the fasted state, activity in the middle frontal and pre- and postcentral gyri was found to be decreased after surgery. In the sated state, activity within the insula was increased before, but not after surgery. Collectively, our results suggest that resting-state neural functions are rapidly affected following bariatric surgery and the associated weight loss and change in diet. © 2016 Federation of European Neuroscience Societies and John Wiley & Sons Ltd.

The increasing number of patients requiring emergency care is a challenge and leads to decreased satisfaction of health professionals at emergency departments (EDs). Thus, a Swiss hospital implemented a hospital-associated primary care centre at the ED. The study aim was to investigate changes in job satisfaction of ED staff before and after the implementation of this new service model and to measure hospital GPs' (HGPs) satisfaction at the hospital-associated primary care centre. This study was embedded in a large prospective before-after study over two years. We examined changes in job satisfaction with a questionnaire followed by selected interviews approaching all of the involved 25 ED staff members and 38 HGPs. The new emergency care model increased job satisfaction of ED staff and HGPs in all measured dimensions. The overall job satisfaction of ED employees improved from 76.5 to 83.9 points (visual analogue scale 0-100; difference 7.4 points [95% CI: 1.3 to 13.5, p = 0.02]). 86% of 29 HGPs preferred to provide their out-of-hours service at the new hospital-associated primary care centre. The hospital-associated primary care centre is a promising option to improve job satisfaction of different health professionals in emergency care. Copyright © 2015 Elsevier Ltd. All rights reserved.

How a nuclear power plant accident influences acceptance of nuclear power: results of a longitudinal study before and after the Fukushima disaster.

Major nuclear accidents, such as the recent accident in Fukushima, Japan, have been shown to decrease the public's acceptance of nuclear power. However, little is known about how a serious accident affects people's acceptance of nuclear power and the determinants of acceptance. We conducted a longitudinal study (N= 790) in Switzerland: one survey was done five months before and one directly after the accident in Fukushima. We assessed acceptance, perceived risks, perceived benefits, and trust related to nuclear power stations. In our model, we assumed that both benefit and risk perceptions determine acceptance of nuclear power. We further hypothesized that trust influences benefit and risk perceptions and that trust before a disaster relates to trust after a disaster. Results showed that the acceptance and perceptions of nuclear power as well as its trust were more negative after the accident. In our model, perceived benefits and risks determined the acceptance of nuclear power stations both before and after Fukushima. Trust had strong effects on perceived benefits and risks, at both times. People's trust before Fukushima strongly influenced their trust after the accident. In addition, perceived benefits before Fukushima correlated with perceived benefits after the accident. Thus, the nuclear accident did not seem to have changed the relations between the determinants of acceptance. Even after a severe accident, the public may still consider the benefits as relevant, and trust remains important for determining their risk and benefit perceptions. A discussion of the benefits of nuclear power seems most likely to affect the public's acceptance of nuclear power, even after a nuclear accident. © 2012 Society for Risk Analysis.

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.

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

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.

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.

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.

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.

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.

1988-01-01

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.

Comparison of doses, before and after remedial action

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 examined hospitalization rates for nursing home residents before and after their entry to the home, stratified by sex and age. A cohort study was conducted using data from a large health insurance fund on 127,227 residents aged 65 years and over newly admitted to a nursing home between January 1, 2010, and December 31, 2014. We assessed hospitalization rates and proportions being hospitalized in 6-month intervals one year before nursing home placement and up to 5 years thereafter. Multiple Poisson regression models were fitted to calculate relative risks (RR). Mean age was 84.0 years and 74.6% of the cohort were females. Hospitalization rates were 194.4 per 100 person-years (PY) in the 12 months before entry to the nursing home and 120.0 per 100 PY thereafter. Rates were highest immediately before entry in both sexes. The influence of age was most pronounced in the 12-7 months before entry (RR: 2.37 for 65-74 vs. 95+ years) and declined thereafter (1.29-1.38 up to month 24 after entry). In contrast, the influence of sex was greater after entry (RR: 1.13 for males vs. females in the 12-7 months before and 1.23-1.31 up to month 24 after entry). Hospitalization rates of nursing home residents are much higher in Germany than in other Western countries. We have provided some insight into the influence of age and sex on hospitalization rates, which varied over the period (time before and after entry to the nursing home) analyzed. We urgently recommend that future studies on the hospitalization of residents stratify their analyses by sex, age and period. Copyright © 2017 Elsevier B.V. All rights reserved.

Full Text Available We studied the chronic effect of thyrotropin releasing hormone (TRH in a patient with spinocerebellar degeneration by measuring cerebral metabolic rate for glucose (CMRG1c using 2-[18F]fluoro-2-deoxy-D-glucose (18FDG and positron emission tomography (PET. A 56-year-old female, who had suffered from progressive ataxia for 2 years, was treated by intravenous administration of 2 mg TRH for 3 weeks, and CMRG1c of the brain was measured before and after treatment. CMRG1c was markedly decreased in the cerebellum and there was no significant difference before and after the treatment, i.e. mean CMRG1c values were 4.92 and 4.90 mg/100 g/min, and the ratios of the cerebellum versus the frontal cortex were 0.50 and 0.51, respectively. The degree of disequilibrium of her body examined with stabilography became better by the 19th day and further improved by the 26th day after the start of TRH treatment. Based on the present study we conclude that long-term administration of TRH did not improve CMRG1c in the cerebellum, but evidently improved the sway of gravity center by stabilography. We speculate that the chronic effect of TRH was not necessarily due to an improvement of cerebellar function, because TRH receptors are widely distributed throughout the central nervous system.

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.

This study aimed to evaluate the misfit of three different implant-abutment connections before and after cycling load. One hundred twenty dental implants and correspondent prefabricated titanium abutments were used. Three different implant-abutment connections were evaluated: Morse taper (MT group), external hexagon (EH group), and internal hexagon (IH group). Forty implants and 40 abutments were used per group. The parameters for the mechanical evaluation were set as: 360,000 cycles, load of 150 N, and frequency of 4 Hz. Samples were sectioned in their longitudinal and transversal axes, and the misfit of the implant-abutment connection was evaluated by scanning electron microscopy analysis. One-way analyses of variance, Tukey post hoc analyses (α = .05), and t test (P .05). Transversally, only the MT group showed full fitting after cycling load compared with the other groups (EH and IH) (P abutment connection in internal, external, and Morse taper connections. In the longitudinal direction, the accommodation decreases and/or eliminates the gap observed initially (before load). In the horizontal direction, Morse cone implant-abutment connections experience a complete accommodation with the elimination of the gap.

Epidemiological analyses demonstrate that pneumonia survivors have a higher risk of myocardial infarction than people with similar load of risk factors for atherosclerotic cardiovascular disease (ASCVD) but without pneumonia. This may be due to a higher baseline burden of ASCVD in patients with pneumonia that is not captured by the accounting of known ASCVD risk factors in epidemiological analyses or to unfavorable accelerating effects of pneumonia on atherosclerosis. We analyzed data from the Multi-Ethnic Study of Atherosclerosis. We identified 54 participants that were hospitalized for pneumonia during study follow-up and that also had assessment of coronary artery calcium (CAC, an objective marker of coronary atherosclerotic burden) before and after this hospitalization. We matched them to 54 participants who were not hospitalized for pneumonia but that had CAC assessments at the same study visits as the pneumonia cases. We compared baseline CAC scores and their progression between groups. Baseline CAC scores were similar in both groups (median [IQR]; 6.3 [0-356.8] in pneumonia participants vs. 10.8 [0-178.3] in controls; p = 0.25). After a median of 4.8 years, the direction and magnitude of CAC score change, and the slope of CAC score progression between groups was also similar (median change [IQR], 21.8 [0 to 287.29] in participants with pneumonia versus 15.8 [0 to 140.94] in controls, p = 0.28; difference in slope, 7.7, 95% CI -9.0 to 24.6, p = 0.18). However, among participants with high baseline ASCVD risk (i.e. ACC/AHA 10-year risk estimate ≥7.5%), participants with pneumonia showed a larger increase in CAC scores (median change [IQR]; 159.10 [38.55-407.34] versus 48.72 [0.97-246.99] in controls; p = 0.02) and a trend towards a steeper slope of CAC score progression (difference in slope, 19.7, 95% CI -6.6 to 45.6, p = 0.07). Pneumonia may accelerate the progression of atherosclerosis in people with high baseline ASCVD risk.

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

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.

To explore antidiabetic medicine prescribing to women before, during and after pregnancy in different regions of Europe. A common protocol was implemented across seven databases in Denmark, Norway, The Netherlands, Italy (Emilia Romagna/Tuscany), Wales and the rest of the UK. Women with a pregnancy starting and ending between 2004 and 2010, (Denmark, 2004-2009; Norway, 2005-2010; Emilia Romagna, 2008-2010), which ended in a live or stillbirth, were identified. Prescriptions for antidiabetic medicines issued (UK) or dispensed (non-UK) during pregnancy and/or the year before or year after pregnancy were identified. Prescribing patterns were compared across databases and over calendar time. 1,082,673 live/stillbirths were identified. Pregestational insulin prescribing during the year before pregnancy ranged from 0.27% (CI95 0.25-0.30) in Tuscany to 0.45% (CI95 0.43-0.47) in Norway, and increased between 2004 and 2009 in all countries. During pregnancy, insulin prescribing peaked during the third trimester and increased over time; third trimester prescribing was highest in Tuscany (2.2%) and lowest in Denmark (0.5%). Of those prescribed an insulin during pregnancy, between 50.5% in Denmark and 88.8% in the Netherlands received an insulin analogue alone or in combination with human insulin, this proportion increasing over time. Oral products were mainly metformin and prescribing was highest in the 3 months before pregnancy. Metformin use during pregnancy increased in some countries. Pregestational diabetes is increasing in many areas of Europe. There is considerable variation between and within countries in the choice of medication for treating pregestational diabetes in pregnancy, including choice of insulin analogues and oral antidiabetics, and very large variation in the treatment of gestational diabetes despite international guidelines.

Women with a pregnancy starting and ending between 2004 and 2010, (Denmark, 2004-2009; Norway, 2005-2010; Emilia Romagna, 2008-2010, which ended in a live or stillbirth, were identified. Prescriptions for antidiabetic medicines issued (UK or dispensed (non-UK during pregnancy and/or the year before or year after pregnancy were identified. Prescribing patterns were compared across databases and over calendar time.1,082,673 live/stillbirths were identified. Pregestational insulin prescribing during the year before pregnancy ranged from 0.27% (CI95 0.25-0.30 in Tuscany to 0.45% (CI95 0.43-0.47 in Norway, and increased between 2004 and 2009 in all countries. During pregnancy, insulin prescribing peaked during the third trimester and increased over time; third trimester prescribing was highest in Tuscany (2.2% and lowest in Denmark (0.5%. Of those prescribed an insulin during pregnancy, between 50.5% in Denmark and 88.8% in the Netherlands received an insulin analogue alone or in combination with human insulin, this proportion increasing over time. Oral products were mainly metformin and prescribing was highest in the 3 months before pregnancy. Metformin use during pregnancy increased in some countries.Pregestational diabetes is increasing in many areas of Europe. There is considerable variation between and within countries in the choice of medication for treating pregestational diabetes in pregnancy, including choice of insulin analogues and oral antidiabetics, and very large variation in the treatment of gestational diabetes despite international guidelines.

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 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.

Our country is in the midst of an opioid epidemic. Although the problem is multifactorial, one issue is the presence of excess prescription opioid medications circulating in our communities. Our objective was to determine whether dissemination of an educational brochure would improve the disposal of unused opioids after surgery. Eligible surgery patients from an upper extremity/peripheral nerve clinic were enrolled into this prospective before and after study between February 2017 and September 2017. Patients who reported opioid use preoperatively were excluded from this study. The same survey was administered to the group of patients who did not receive the intervention and to those who did receive the intervention. Our primary endpoint was the proportion of patients who disposed of unused opioid medications. A total of 334 patients were studied: 164 who did not receive the brochure and 170 who received the brochure. Seventy-six patients were excluded for preoperative opioid use. After dissemination of the brochure, there was a significant increase in the proportion of patients who disposed of their unused opioids (11% vs 22%, p = 0.02). Of those who disposed of their opioids, there was no significant difference in the proportion of patients from each group who disposed in a manner that was recommended by the brochure (43% vs 64%, p = 0.19). Dissemination of the educational brochure improved disposal of unused opioids after surgery. This low-cost, easily implemented intervention can improve disposal of unused opioids and ultimately, decrease the amount of excess opioids circulating in our communities.

Little is known about hemodynamic disturbances affecting cerebral hemispheres in traumatic brain injury (TBI) after cranioplasty. We prospectively investigated six stable TBI patients who underwent cranioplasty more than 90 days after effective decompressive craniectomy. Computerized tomography perfusion (CTP) studies and evaluation of clinical outcome were performed for each patient before cranioplasty and at 7 days and 3 months after surgery. Cerebral blood flow (CBF), cerebral blood volume (CBV) and mean transit time (MTT) were measured in multiple cortical circular regions positioned in cranioplasty-treated and contralateral hemispheres. Neither complications associated with cranioplasty nor changes in outcome were observed. On the treated side, CBF and CBV values were higher before and 7 days after cranioplasty than at 3 months after surgery, whereas MTT values were lower at 7 days than at 3 months after surgical treatment. Our results indicate that cortical perfusion progressively declines in the cranioplasty treated hemisphere but remains stable in the contralateral hemisphere after surgery and suggest that CTP can represent a promising tool for a longitudinal analysis of hemodynamic abnormalities occurring in TBI patients after cranioplasty. In addition, these data imply a possible role of cranioplasty in restoring flow to meet the prevailing metabolic demand. (orig.)

Full Text Available Background: Multiple Sclerosis disease is a chronic disease of nervous system which causes different symptoms. Although headache is not a major symptom of this disease, but a lot of patients suffer from it. To specify the prevalence of headache and its’ types has an important role in diagnose, treatment and improvement the quality of patients’ life. Objective: Our goal of this study was to determine the prevalence of headache in multiple sclerosis patients, before and after the diagnosis of this disease. Methods: This cross-sectional descriptive epidemiologic study was performed on 150 multiple sclerosis patients referred to the neurology clinic of Qazvin in 2015. Data were recorded by history taking & physical examination the existence of headache before the MS diagnosis and at the time of study was evaluated by the patients’ data. Findings: Among participants, prevalence of headache before the MS diagnosis was 40%, which increased to 64% after that (P<0.001. The most common type of headache, before and after the affection was tension headache, which formed 58.3% and 70.8% of all headaches, respectively. The average rate of headache in the group with headache, before and after the diagnosis of MS was 5.8 and 5.76 days in month, which calculated 2.32 and 3.68 days in month in all patients, respectively. Conclusion: Prevalence of headache increases in multiple sclerosis patients. Patients suffer from headache almost 13% of their life days.

To describe the effect of interventions designed to improve patient identification (PI) during pathology collection in the ED. A prospective before-and-after intervention study was conducted between June 2009 and June 2010 in a regional ED in Queensland, Australia. Interventions aimed to improve PI and specimen labelling, and consisted of: (i) education alone; and (ii) education plus an armband scanner that voice-prompted collector behaviour. Main outcomes measured included: frequency of correct key behaviours (KBs) during specimen collection, pathology integrity errors and cost of interventions. Data from 282 ED pathology collections were analysed (before: n = 115, after with education: n = 95, after with education plus armband scanner: n = 72). KBs for PI and labelling improved significantly following education plus armband scanner use. Application of armbands before sample collection increased (36% vs 90%, P patient to state their name (25% vs 93%, P patient misidentification was detected in this small study. The annual costs for a hospital to adopt the education programme with and without the armband scanner were $104,045 and $5330 respectively. ED staff had poor behaviours for identifying patients and labelling pathology specimens before intervention. These safety behaviours were considered an assumed skill. Education alone improved critical KBs markedly that was further augmented by the armband scanner. The cost to adopt education alone is relatively low compared to the addition of armband scanner technology. © 2015 The Authors.

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.

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.

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

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.

During solitary sailing the sailor is exposed to sleep deprivation and difficulties in consuming regular meals. Sailor weight loss is often reported. In the present case study we describe changes in the physical capacity and the nutritional status of an athlete attempting a single-handed yacht race around the globe. An Italian male ocean racer (GM) asked for our help to reach an optimum level of physical and nutritional preparation. We planned his diet after assessing his anthropometric parameters and body composition as well as his usual energy intake and nutritional expenditure. The diet consisted in 120 meals stored in sealed plastic bags. Before his departure, GM performed two incremental exercise tests (cycle- and arm crank- ergometry) to assess his physical capacity. Cardiac functions were also estimated by Doppler echocardiography. All measures and exercise tests were repeated 10 days after GM finished the race, which lasted 64 days. Anthropometric measures did not change significantly, with the exception of Arm Fat Area and Thigh Muscle area, which decreased. There were evident increments in maximum oxygen intake and maximum workload during arm cranking after the race. On the contrary, maximum oxygen uptake and maximum workload decreased during cycling. Finally, End Diastolic and Stroke Volume decreased after the race. It was concluded that nutritional counseling was useful to avoid excessive changes in the nutritional status and body composition due to 64 days of solitary navigation. However, a reduction in physical leg capacity and cardiovascular functions secondary to legs disuse were present.

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

Smoking is a major risk factor for bladder cancer, but the relationship between smoking cessation after initial treatment and bladder cancer recurrence has been investigated less frequently and not prospectively yet. 722 non-muscle-invasive bladder cancer (NMIBC) patients (pTa, pT1, and CIS) from the prospective Bladder Cancer Prognosis Programme (BCPP) cohort, selected in the UK between 2005 and 2011, provided complete data on smoking behavior before and up to 5 years after diagnosis. The impact of smoking behavior on NMIBC recurrence was explored by multivariable Cox regression models investigating time-to-first NMIBC recurrence. Over a median follow-up period of 4.21 years, 403 pathologically confirmed NMIBC recurrences occurred in 210 patients. Only 25 current smokers at diagnosis quit smoking (14%) during follow-up and smoking cessation after diagnosis did not decrease risk of recurrence compared to continuing smokers (p = 0.352). Although quitting smoking after diagnosis might reduce the risk of recurrence based on retrospective evidence, this is not confirmed in this prospective study because the number of NMIBC patients quitting smoking before their first recurrence was too low. Nevertheless, this indicates an important role for urologists and other health care professionals in promoting smoking cessation in NMIBC.

Objective: To assess the clinical effect and necessity of interventional treatment in diabetic foot before and after amputation. Methods: Combined intravascular angioplasty with intraarterial medicine perfusing were carried out in fourteen patients with diabetic foot including 10 patients treated before amputation and 4 after amputation involving superficial femoral, deep femoral, tibial and fitular arteries. Among them seventeen vessels with irregular stenosis and obstruction were treated by intravascular angioplasty through balloon dilation. Results: The technical successful rate was 100%, no complication happened. The symptoms were relieved in all patients after treatment, including promotion of lower extremity arterial blood perfusion, reducing range of amputation and wound healing after amputation. Conclusions: Intravascular interventional treatment is safe, effective and valuable in diabetic foot before and after amputation. (authors)

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.

Abortion was legalized in many states in India in April 1972. This study deals with 2 groups of patients admitted to P.G.I., Chadigarh, with problems of induced septic abortion. Group 1 consisted of 88 patients admitted during the 2 1/2 year period from 1 July 1969 to 31 December 1971, before the legalization of abortion. Group 2 consists of 133 patients admitted during the 2 1/2 year period from 1 July 1973 to 31 December 1975. 1 year after the new abortion law had been in force. Not only has there been an increase in the total number of patients, there has been an increase in the severity of infection. Evidently, the liberalization of the law has encouraged more patients to seek abortions and has encouraged more doctors, lacking proper qualifications, to perform them. The morbidity and mortality with induced septic abortion can only be reduced if enough public propaganda makes the people especially in rural areas conscious of the hazards of induced abortion by "dais" and unqualified personnel, simultaneously making them aware of the provision of law and facilities available at different centers. Meanwhile, the law against unskilled and untrained personnel should be rigorously enforced.

Little is known about medication use among women with eating disorders in relation to pregnancy. To explore patterns of and associations between use of psychotropic, gastrointestinal and analgesic medications and eating disorders in the period before, during and after pregnancy. This study is based on the Norwegian Mother and Child Cohort Study (MoBa). A total of 62,019 women, enrolled at approximately 17 weeks' gestation, had valid data from the Norwegian Medical Birth Registry and completed three MoBa questionnaires. The questionnaires provided diagnostic information on broadly defined anorexia nervosa (AN), bulimia nervosa (BN), binge eating disorder (BED) and recurrent self-induced purging in the absence of binge eating (EDNOS-P), along with self-reported use of medication six months before, during, and 0-6 months after pregnancy. The prevalence of eating disorder subtypes before and/or during pregnancy was: 0.09% AN (n = 54), 0.94% BN (n = 585), 0.10% EDNOS-P (n = 61) and 5.00% BED (n = 3104). The highest over-time prevalence of psychotropic use was within the AN (3.7-22.2%) and EDNOS-P (3.3-9.8%) groups. Compared to controls, BN was directly associated with incident use of psychotropics in pregnancy (adjusted RR: 2.25, 99% CI: 1.17-4.32). Having AN (adjusted RR: 5.11, 99% CI: 1.53-17.01) or EDNOS-P (adjusted RR: 6.77, 99% CI: 1.41-32.53) was directly associated with use of anxiolytics/sedatives postpartum. The estimates of use of analgesics (BED) and laxatives (all eating disorders subtypes) were high at all time periods investigated. Use of psychotropic, gastrointestinal, and analgesic medications is extensive among women with eating disorders in the period around pregnancy. Female patients with eating disorders should receive evidence-based counseling about the risk of medication exposure versus the risk of untreated psychiatric illness during pregnancy and postpartum.

In Japan, monovalent and pentavalent rotavirus (RV) vaccines were approved in 2011 and 2012, respectively. To monitor changes in the RV genotypes before and after vaccine introduction, we performed a prospective observational study among children (＜ 5 years) with gastroenteritis who tested RV-positive on antigen rapid tests. Stool samples were collected from 3 different sites in Japan: Tsu City, Mie Prefecture; Kurashiki City, Okayama Prefecture; and Isumi City, Chiba Prefecture. RV genotypes were determined using reverse transcription-polymerase chain reaction. In Tsu City, G3P[8] was dominant (61.0-77.1%) before vaccine introduction, but decreased after introduction. Meanwhile, in an inverse proportion to the decrease in G3P[8], G1P[8] increased until the 2013/14 season, when a sudden predominance of G2P[4] (100%) occurred. A similar trend was observed in Kurashiki City in terms of the extent of reduction in G3P[8] and the emergence of G2P[4]. In Isumi City, G1P[8] was dominant (70.3%) before vaccine introduction, and G9P[8] became predominant (83.3%) in the 2013/14 season. To determine whether the genotype changes are attributable to vaccines or natural epidemiological changes, ongoing continuous monitoring of the RV genotypes is required.

We report on the effectiveness of a standardized perioperative care process for lowering surgical site infection (SSI) rates among children with stoma closure at a tertiary-care public pediatric teaching hospital in Mexico City. All consecutive children with stoma closure operated on between November 2003 and October 2005 were prospectively followed for 30 days postoperatively. We conducted a before-after study to evaluate standardized perioperative bowel- and abdominal-wall care process results on SSI rates. Seventy-one patients were operated on, and all completed follow-up. SSI rates declined from 42.8% (12/28) before to 13.9% (6/43) after the standardization procedure (relative risk (RR) = 3.1; 95% confidence interval (CI) = 1.3-7.2; p = 0.006). SSI independently associated risk factors comprised peristomal skin inflammation >3 mm (odds ratio (OR) = 9.6; 95% CI = 1.8-49.6; p = 0.007) and intraoperative complications (OR = 13.3; 95% CI = 1.4-127.2; p = 0.02). Being operated on during the after-study period was shown to be a protective factor against SSI (OR = 0.2; 95% CI = 0.4-0.97; p = 0.04). Standardization was able to reduce SSI rates threefold in children with stoma closure in a short period of time.

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.

Ship wakes produced by deep-draft vessels transiting the lower Columbia River have been observed to cause stranding of juvenile salmon. Proposed deepening of the Columbia River navigation channel has raised concerns about the potential impact of the deepening project on juvenile salmon stranding. The Portland District of the U.S. Army Corps of Engineers requested that the Pacific Northwest National Laboratory design and conduct a study to assess stranding impacts that may be associated with channel deepening. The basic study design was a multivariate analysis of covariance of field observations and measurements under a statistical design for a before and after impact comparison. We have summarized field activities and statistical analyses for the ?before? component of the study here. Stranding occurred at all three sampling sites and during all three sampling seasons (Summer 2004, Winter 2005, and Spring 2005), for a total of 46 stranding events during 126 observed vessel passages. The highest occurrence of stranding occurred at Barlow Point, WA, where 53% of the observed events resulted in stranding. Other sites included Sauvie Island, OR (37%) and County Line Park, WA (15%). To develop an appropriate impact assessment model that accounted for relevant covariates, regression analyses were conducted to determine the relationships between stranding probability and other factors. Nineteen independent variables were considered as potential factors affecting the incidence of juvenile salmon stranding, including tidal stage, tidal height, river flow, current velocity, ship type, ship direction, ship condition (loaded/unloaded), ship speed, ship size, and a proxy variable for ship kinetic energy. In addition to the ambient and ship characteristics listed above, site, season, and fish density were also considered. Although no single factor appears as the primary factor for stranding, statistical analyses of the covariates resulted in the following equations: (1) Stranding

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.

The attitude of nurses influences their application of the Advanced Nursing Process. Studies reveal deficits in the application of the Advanced Nursing Process that is based on valid assessments and nursing classifications. These deficits affect decision-making and – as a result – nursing care quality. In German speaking countries nurses' attitudes towards nursing diagnoses as part of the Advanced Nursing Process were not yet measured. The aim of this study was to evaluate the effects of an educational intervention on nurses' attitude. A quasi-experimental intervention study was carried out in Austria and Germany. Before and after a standardised educational intervention 51 nurses estimated their attitude with the instrument Positions on Nursing Diagnosis (PND). Analyses were performed by Wilcoxon- and U-tests. Before the educational intervention the average attitude score of the Austrian nurses was more positive than in the German group. After the study intervention both groups regarded nursing diagnostics statistically significant more convincing and better understandable. However, both groups still described the application of the Advanced Nursing Process as difficult and demanding to perform. In the future, more attention should be given to the reflexion and development of nurses' attitude towards the Advanced Nursing Process because attitudes lead nurses' actions. In further studies influencing organizational and structural factors in diverse settings will be analysed.

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.

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.)

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.

Women have higher morning serum zolpidem concentrations than men after taking an evening dose, potentially leading to increased risk of harm. On 19 April 2013, the United States Food and Drug Administration required labeling changes for zolpidem, recommending an initial dose of no greater than 5 mg (immediate release) or 6.25 mg (controlled release) per night in women. The primary objective of this study was to compare prescribing practices before and after the 2013 zolpidem labeling change. A secondary objective was to evaluate serious adverse events potentially related to zolpidem. Electronic medical records of adults receiving care through the University of Colorado Health system were accessed for study inclusion if patients were provided a first-time prescription for zolpidem either prior to or after the Food and Drug Administration labeling change. Patients were randomly chosen from eight strata based on age, gender, and date of zolpidem initiation (before/after the labeling change). Demographic and zolpidem prescribing data were collected. Low-dose zolpidem was considered 5 mg (immediate release) or 6.25 mg (controlled release) daily or less. Documentation of potentially related serious adverse events within the patients' records was also evaluated. A total of 400 patients were included in the study. The overall percentage of patients prescribed low-dose zolpidem increased from 44% to 58% after the labeling change (p = 0.0020). In a pre-specified subgroup analysis, the percentage of patients prescribed low-dose zolpidem increased in all groups, including young men (38%-50%, p = 0.23), elderly men (34%-40%, p = 0.53), and elderly women (60%-74%, p = 0.14), but the change was only significant in young women (42%-70%, p = 0.0045).

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.

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

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)

Literature suggests that serious mental health problems increase the use of health services and psychological interventions can reduce this effect. This study investigates whether this effect is also found in primary care patients with less serious mental health problems. Routine electronic health records (EHR) from a representative sample of 128 general practices were linked to patient files from 150 primary care psychologists participating in the NIVEL Primary Care Database, using a trusted third party. Data were linked using the date of birth, gender, and postcode. This yielded 503 unique data pairs that were listed in one of the participating GP practices in 2008-2010, for people who had psychological treatment from a psychologist that ended in 2009. The number of contacts, health problems presented, and prescribed medication in general practice were analysed before and after the psychological treatment. Nearly all 503 patients consulted their GP during the six months preceding the psychological treatment (90.9%) and also in the six months after this treatment had ended (83.7%). The frequency of contacts was significantly higher before than after the psychological treatment (6.1 vs. 4.8). Fewer patients contacted their GPs specifically for psychological or social problems (46.3% vs. 38.8%) and fewer patients had anxiolytic drug prescriptions (15.5% vs. 7.6%) after psychological treatment. After psychological treatment, patients contact their GPs less often and present fewer psychological or social problems. Although contact rates seem to decrease, clients of psychologists are still frequent GP attenders.

MITOCHONDRIAL DYNAMICS IN PRE- AND POSTPUBERTAL PIG OOCYTES BEFORE AND AFTER IN VITRO MATURATION

Oocytes from prepubertal (PRE) or postpubertal (POST) pigs are used in, for example, somatic cell nuclear transfer and in vitro fertilization. Here we describe mitochondrial dynamics in pig oocytes of different sizes before and after in vitro maturation (IVM), isolated from PRE or POST animals....... In PRE oocytes, inside-zona pellucida diameter was measured before and after IVM (μm; small: ≤110, medium: >110, large: ≥120) and used for evaluation of (1) mitochondrial numbers before maturation and (2) mitochondrial morphology and location before and after maturation in comparison with POST oocytes....... Oocytes were processed for transmission electron microscopy (Acta Anat. 129:12). For assessment of mitochondrial numbers, paired dissector sections were collected at uniform intervals throughout the oocyte, and in each set of dissector sections a known area fraction was sampled for mitochondrial counting...

Full Text Available ABSTRACT Aim: To evaluate life quality of elderly people with acquired low vision before and after hearing and speech intervention. Methods: This was a descriptive cross-sectional study. The study was made with 52 elderly people with acquired low vision. Two questionnaires that measures life quality were used in this study. The first was ‘Low Quality of Life Vision (LVQOL’ and the second the ‘National Eye Institute Visual Function Questionnaire (NEIVFQ-25’. The study included people with more than 60 years with acquired low vision and who accepted to participate signing the consent form. The hearing and speech therapy were made into three months, one meeting a week. The questionnaires were applied in the first and last day of the intervention. Results: The age ranged between 60 and 91 years. The macular disorder (38%, such as age-related macular degeneration, macular hole and high myopia were the main causes of visual loss. Although the tests show superior performance after the intervention, there was no statistically significant difference. On the question about difficulties seeing in general, 17 participants answered that they had much more difficulty before the intervention and only 5 participants have reported having much difficulty after the intervention. Conclusion: The intervention trended to positive results, and after the meetings, participants showed improvements in aspects of the two questionnaires used in the study, decreasing the degree of difficulty in performing activities.

This study compared the flow rate and pH of resting (unstimulated) and stimulated whole saliva before and after complete denture placement in different age groups. Fifty healthy, non-medicated edentulous individuals of different age groups requiring complete denture prostheses were selected from the outpatient department. The resting (unstimulated) and stimulated whole saliva and pH were measured at three stages i.e., i)Before complete denture placement;ii)Immediately after complete denture placement; andiii)After 2 to 3 months of complete denture placement. Saliva production was stimulated by chewing paraffin wax. pH was determined by using a digital pH meter. Statistically significant differences were seen in resting(unstimulated) and stimulated whole salivary flow rate and pH obtained before, immediately after, and after 2 to 3 months of complete denture placement. No statistically significant differences were found between the different age groups in resting (unstimulated) as well as stimulated whole salivary flow rate and pH. Stimulated whole salivary flow rates and pH were significantly higher than resting (unstimulated) whole salivary flow rates and pH obtained before, immediately after, and after 2 to 3 months of complete denture placement. No age related variations in whole salivary flow rate and pH were observed in healthy, non-medicated individuals. The assessment of salivary flow rate, pH in different age groups is of prognostic value, which is an important aspect to be considered in the practice of removable prosthodontics.

We studied how children with epilepsy (CWE) who are candidates for epilepsy surgery, perceive themselves with respect to overarching personality traits and whether the traits change after surgery. We explored influences of demographic and illness variables. A total of 23 CWE [mean age at inclusion 12.8 (sd 2.3); 12 girls] participated. Using the Dutch Personality Questionnaire Juniors (DPQ-J), we assessed 20 of the CWE shortly before epilepsy surgery and compared the results to those of 39 age- and gender-matched healthy controls. Furthermore, we obtained follow-up scores 6, 12 and 24 months after epilepsy surgery from the clinical group. CWE who were candidates for epilepsy surgery scored above average in inadequacy, perseverance, social inadequacy and recalcitrance, whereas healthy peers scored average. Over the two years' period after epilepsy surgery we found no changes, apart from a decrease of social inadequacy. Sporadic illness and demographic variables were related to some personality traits. However, neither post-surgical seizure freedom nor cessation of AEDs did noticeably change the self-evaluations of CWE. Asking CWE to evaluate their personality themselves may offer a shared basis for individually tailored behavior intervention in order to help them adapting to their ameliorated circumstances after surgery.

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.

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.

Concurrent chemoradiotherapy (CCRT) for patients with advanced head or neck cancer has become popular as an effective treatment that can preserve their organs and functions after treatment. However, severe dysfunctions as the complications related to CCRT, e.g. dysphagia, sometimes appear in spite of preservation of the affected organs. The aim of the present study is to clarify swallowing function during and after CCRT. Medical records of subjects who received CCRT for treatment of oropharyngeal (21 cases) and hypopharyngeal (19 cases) cancer were retrospectively reviewed for mucositis and dysphagia before, during, and after CCRT using National Cancer Institute-Common Toxicity Criteria (NCI-CTC) version 2.0. Severity of mucositis and dysphagia kept deteriorating during CCRT and 27.5% of the subjects required tube feeding at the end of CCRT. The mucositis improved rapidly after treatment, but severe dysphagia still persisted in 7.5% of the subjects 6 months after CCRT. Planned neck dissections were carried out in 14 patients as additional treatment against lymph node involvement. Although severe dysphagia appeared immediately after surgery, swallowing function returned to preoperative condition within 1 month. The majority of patients who receive CCRT recover their swallowing function within 6 months after CCRT. However, since some patients demonstrate prolonged dysphagia after CCRT, we should receive informed consent from patients about their swallowing condition after CCRT. (author)

2010-01-01

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

The aim was to evaluate changes in chromogranin A (CgA) concentration in hyperthyroidism and to assess its metabolic correlations. We studied CgA levels in hyperthyroidism. First, 38 hyperthyroid patients matched with 86 normal controls were studied after an overnight fast. Second, 30 if the 38 patients were followed up for 6 months with medical antithyroid drug therapy (carbimazole). In the first study, after 10-12 h overnight fasting, blood was collected for measurement of CgA, glucose, insulin, intact proinsulin, and thyroid function. These variables were remeasured in the second study for the patients after attainment of euthyroidism with the antithyroid drug carbimazole for 6 months. Pretreatment CgA level was significantly higher in patients compared with controls. CgA levels dropped significantly to levels similar to those of controls after antithyroid therapy. Although baseline and follow-up fasting glucose, insulin, and intact proinsulin demonstrated similar pattern of CgA changes before and after medical treatment, CgA did not correlate with any of them. However, CgA levels demonstrated a significant positive correlation with free T(3) and free T(4) only. These studies demonstrate that untreated hyperthyroidism is associated with elevated CgA level that changes in parallel to thyroid status. It is therefore possible to use CgA concentration as a potential marker of disease activity in hyperthyroidism.

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.

The aim of this study was to evaluate and compare the functional results before and after laparoscopic Heller myotomy for Iranian patients with achalasia. Achalasia is a severe neuromuscular disorder of the esophagus, characterized by the loss of peristalsis and an inability of the lower esophageal sphincter (LES) to reach optimal relaxation. In this cross sectional study, patients who underwent Heller myotomy for achalasia via laparoscopy in Taleghani Hospital Tehran, Iran were evaluated. Symptoms including pressure of residual, integrated relaxation sphincter (IRP), pressure of free drinking, pressure of LES, dysphasia score and peristalsis movement was measured and recorded by manometry before and after (2 months) treating with Heller myotomy. In this study, 23 patients with achalasia (12 females and 11 males) with a mean age of 30±3.5 years (minimum 20, maximum 44 years) who met the inclusion criteria of the study were examined. Results of this study showed that, all the diagnostic criteria that were measured before the treatment was significantly different from after the treatment (PHeller myotomy surgery can be as a treatment of choice for achalasia. Free Drinking pressure can be a suitable criteria after treatment for evaluation and prediction of the reducing the dysphasia score after the surgery.

This experimental study examined lesions produced by a hatchet on pig femurs before and after carbonization. A total of 30 lesions were produced and analyzed using stereomicroscopy and then reexamined after carbonization. Not only was the sharp-blunt mechanism of the hacking trauma (V-shape, regularity of one edge, irregularity of the other edge, upraising, lateral pushing back, fossae dug laterally to the edge) still recognizable after carbonization; in some instances, the carbonization actually enhanced the features observed. Carbonization also did not significantly alter the measurements of the lesions. Carbonization tends to alter the structure of the bone especially in areas weakened by the blunt trauma.

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.

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.

The authors evaluated whether a psychiatric clerkship reduces stigmatized attitudes towards people with mental illness among medical students. A 56-item questionnaire was used to assess the attitudes of medical students towards patients with mental illness and their beliefs about its causes before and after their participation in their psychiatric clerkship at a major medical school in Rio de Janeiro. Exploratory factor analysis identified four factors, reflecting "social acceptance of people with mental illness," "normalizing roles for people with mental illness in society," "non-belief in supernatural causes for mental illness," and "belief in bio-psychosocial causes for mental illness." Analysis of variance was used to evaluate changes in these factors before and after the clerkship. One significant difference was identified with a higher score on the factor representing social acceptance after as compared to before the clerkship (p = 0.0074). No significant differences were observed on the other factors. Participation in a psychiatric clerkship was associated with greater social acceptance but not with improvement on other attitudinal factors. This may reflect ceiling effects in responses before the clerkship concerning supernatural and bio-psychosocial beliefs about causes of mental illness that left little room for change.

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

Materials and Methods: Fifty healthy, non-medicated edentulous individuals of different age groups requiring complete denture prostheses were selected from the outpatient department. The resting (unstimulated) and stimulated whole saliva and pH were measured at three stages i.e., i)Before complete denture placement;ii)Immediately after complete denture placement; andiii)After 2 to 3 months of complete denture placement. Saliva production was stimulated by chewing paraffin wax. pH was determined by using a digital pH meter. Results: Statistically significant differences were seen in resting(unstimulated) and stimulated whole salivary flow rate and pH obtained before, immediately after, and after 2 to 3 months of complete denture placement. No statistically significant differences were found between the different age groups in resting (unstimulated) as well as stimulated whole salivary flow rate and pH. Conclusion: Stimulated whole salivary flow rates and pH were significantly higher than resting (unstimulated) whole salivary flow rates and pH obtained before, immediately after, and after 2 to 3 months of complete denture placement. No age related variations in whole salivary flow rate and pH were observed in healthy, non-medicated individuals. Clinical Implications: The assessment of salivary flow rate, pH in different age groups is of prognostic value, which is an important aspect to be considered in the practice of removable prosthodontics.

Full Text Available We studied the use ofnon-steroid anti-inflammatorydrugs (NSAID at the in-patient department ofcentral district hospitalwith the application ofDDD-techniques before and after the formular system adoption. After introduction of drug formular and treatment standards the use of NSAID was reduced; the physicians began to use modern drugs. Non-indicated and contraindicated NSAID were prescribed more seldom. Itwas determined that reduction of antihypertensive drugs efficiency in hypertensive patients was the main side effect of NSAID use. NSAID gastropathy occurred more seldom, and mainly in the patients receiving several NSAIDs simultaneously.

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

The effectiveness of a hospital information system (HIS) and a radiological information system (RIS) was evaluated to optimize preparation for the planned full clinical operation of a picture archiving and communication system (PACS), which is now linked experimentally to the HIS and the RIS. One thousand IC (integrated circuit) cards were used for time studies and flow studies in the hospital. Measurements were performed on image examination order entry, image examination, reporting, and image delivery times. Even though after the HIS and the RIS operation only a small amount of time savings were realized in each time fraction component, such as in the patient movement time, examination time, and film delivery time, the total turn-around time was shortened markedly, by more than 23 hours on average. It was verified that the HIS and the RIS was beneficial in the outpatient clinics of the orthopedic department. Our method of measurement employing IC cards before and after HIS and RIS operations can be applied in other hospitals.

High hospitalization rates, prolonged length of stay, and increased risks of subsequent events mean a steep increase in health care usage after stroke. No study, however, has examined to what extent increased costs after transient ischemic attack (TIA) or stroke are due to hospitalizations for the initial event, recurrent events, and/or nonvascular hospitalizations, and how costs compare with the year prior to the event. We studied patients in a population-based cohort study (Oxford Vascular Study) in the United Kingdom from 2003 to 2007. Hospitalization and cost details were obtained from patients' individualized Hospital Episode Statistics records. A total of 295 incident TIA and 439 incident stroke patients were included. For patients with stroke, average costs increased from £1437 in the year pre-event to £6629 in the year post-event (PTIA, costs increased from £876 1 year before the event to £2410 in the year post-event (PTIA incurred nonsignificantly higher costs due to hospitalizations linked to subsequent vascular events (£774) than for hospitalizations linked to the index TIA (£720). Hospital costs increased after TIA or stroke, primarily because of increased initial cerebrovascular hospitalizations. The finding that costs due to nonvascular diagnoses also increased after TIA or stroke appears, in part, to be explained by the miscoding of TIA/stroke-related hospitalizations in electronic information systems.

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

Cavernous angiomas (CA) are easily diagnosed by MRI. Its epileptogenic and hemorrhagic potential leads towards surgery without letting definitive conclusion to be drawn concerning the evolution of the neighbouring tissues. An epileptogenic focus may entail a reduction in the regional metabolism, so we used the FDG: 1. to establish the presence and extension of peri-lesion metabolic modifications; 2. to study whether the CA resection could modify, on site or at a distance, the cerebral metabolism. We have selected 15 patients with epileptogenic CAs observed by MRI. Under EEG surveillance we have measured in the inter-ictal period the regional cerebral carbohydrate metabolism (MCRGlu) before and after a limited resection of a CA. The histology confirmed the diagnosis and studied the cerebral tissue adherent to the lesion. The global MCRGlu of brain has not varied after surgery (8.33 ± 1.15 vs 8.33 ± 1.70 ml/min/100 g). The CA containing hemisphere had a diminished MCRGlu (2 factor ANOVA, p < 0.02). The regions close to the lesion in the afflicted hemisphere itself, were less metabolic than those more distant (3 factor ANOVA, p < 0.04). This aspects has been not modified by the surgery. A table is given showing the values of MCRGlu before and after intervention. The metabolic gradient in the neighbourhood of lesion is insufficient in helping to determine the limits of surgery. The modifications undergone by the potentially epileptogenic tissue are not any more notable. The absence of post surgery variations indicates that the metabolic consequences of the lesion are replaced by those of restructuring. Hence, the cerebral surgery does not cause metabolic variations which could perturb further evolution following a limited intervention and for a long enough time interval after the intervention

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.

This qualitative descriptive study was undertaken in two metropolitan ICUs utilising focus groups to describe the ways in which ICU nurses care for the families of dying patients during and after the death. Participants shared their perspectives on how they care for families, their concerns about care, and detailed the strategies they use to provide timely and person-centred family care. Participants identified that their ICU training was inadequate in equipping them to address the complex care needs of families leading up to and following patient deaths, and they relied on peer mentoring and role-modelling to improve their care. Organisational constraints, practices and pressures impacting on the nurse made 'ideal' family care difficult. They also identified that a lack of access to pastoral care and social work after hours contributed to their concerns about family care. Participants reported that they valued the time nurses spent with families, and the importance of ensuring families spent time with the patient, before and after death.

Full Text Available The aim of the present study was the morphometric evaluation of the epithelial lining and fibrous capsule in histological specimens of keratocystic odontogenic tumors (KOTs before and after marsupialization. Histological sections from six KOTs that had undergone marsupialization followed by enucleation were photographed. The thickness and features of the capsule and of the epithelial lining of the tumor were evaluated upon marsupialization and upon subsequent enucleation using Axion Vision software. The histological specimens taken upon marsupialization presented an epithelial lining that is typical of KOTs. After marsupialization, the enucleated specimens had a modified epithelial lining and a fibrous capsule that both presented a greater median thickness (p = 0.0277 and p = 0.0212, respectively, morphological changes, and significant enlargement. These modifications can facilitate full surgical treatment and may well be related to a low KOT recurrence rate.

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

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

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

Full Text Available A total of 47 racing greyhounds were enrolled in this study on two race days (in July and September, resp. at a racetrack. Twelve of the dogs participated in the study on both days. Thermographic images were taken before and after each race. From the images, superficial temperature points of selected sites (tendo calcaneus, musculus gastrocnemius, musculus gracilis, and musculus biceps femoris portio caudalis were taken and used to investigate the differences in superficial temperatures before and after the race. The thermographic images were compared between the right and left legs of a dog, between the raced distances, and between the two race days. The theoretical heat capacity of a racing greyhound was calculated. With regard to all distances raced, the superficial temperatures measured from the musculus gastrocnemius were significantly higher after the race than at baseline. No significant differences were found between the left and right legs of a dog after completing any of the distances. Significant difference was found between the two race days. The heat loss mechanisms of racing greyhounds during the race through forced conduction, radiation, evaporation, and panting can be considered adequate when observing the calculated heat capacity of the dogs.

Our previous retrospective study suggested that red blood cell (RBC) transfusion of preterm neonates can be associated with an increase in bilirubin, but this has not been tested prospectively. We studied neonates before and after RBC transfusions, recording serial bilirubin levels and whether they qualified for phototherapy. Because lysed RBCs release plasma-free hemoglobin (Hb), a precursor to bilirubin, we also measured plasma free Hb and bilirubin from the donor blood. We studied 50 transfusions given to 39 neonates. Gestation ages of transfused neonates, at birth, were 26 (24-29) weeks (median [interquartile range]); birthweights were 750 (620-1070) g. The study transfusion was given on Day of Life 9.9 (3.4-19.2). In 20% (10/50) phototherapy was being administered at the beginning of and during the transfusion. In these patients neither the 4- to 6- nor the 24- to 36-hour-posttransfusion bilirubin levels were significantly higher than before transfusion. However, in 30% of the others (12/40) phototherapy was started (or restarted) after the transfusion and 15% had a posttransfusion bilirubin increase of at least 2.5 mg/dL. These neonates received donor blood with a higher plasma-free Hb (p bilirubin increase of at least 2.5 mg/dL. We speculate that neonates qualifying for a RBC transfusion, who are judged to be at high risk for bilirubin-induced neurotoxicity, might benefit from checking their serum bilirubin level after the transfusion and providing donor blood with low plasma-free Hb levels. © 2016 AABB.

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.

This purpose of this study was to document and investigate changes in periodontal pathogen levels before, during, and after orthodontic treatment in adolescents. DNA gene probe analysis was used to quantify the levels of 8 periodontal pathogens before, during, and after treatment with fixed orthodontic appliances in 190 concurrently treated adolescent orthodontic patients. The 8 pathogens examined were Actinobacillus actinomycetemcomitans (AA), Porphyromonas gingivalis (PG), Prevotella intermedia (PI), Tannerella forsythia (TF), Eikenella corrodens (EC), Fusobacterium nucleatum (FN), Treponema denticola (TD), and Campylobacter rectus (CR). Chi-square tests were used to determine whether the percentages of subjects with high counts significantly changed over time. Logistic regression analyses were also performed to derive the relative risk of higher counts of pathogenic bacteria with fixed appliances at the various time intervals studied. For 6 (PI, TF, EC, FN, TD, CR) of the 8 pathogens, the percentages of subjects with high pathogen counts increased significantly after 6 months of fixed appliance treatment, but these returned to pretreatment levels by 12 months of orthodontic treatment. No pathogen level was significantly higher after 12 months of orthodontic treatment, and orthodontic treatment was found to be significantly protective for half of the pathogens (EC, FN, TD, CR) posttreatment. Orthodontic treatment with fixed appliances does not increase the risk of high levels of these periodontal pathogens.

Gait retraining using visual biofeedback has been reported to reduce impact loading in runners. However, most of the previous studies did not adequately examine the level of motor learning after training, as the modified gait pattern was not tested in a dual-task condition. Hence, this study sought to compare the landing peak positive acceleration (PPA) and vertical loading rates during distracted running before and after gait retraining. Sixteen recreational runners underwent a two-week visual biofeedback gait retraining program for impact loading reduction, with feedback on the PPA measured at heel. In the evaluation of PPA and vertical loading rates before and after the retraining, the participants performed a cognitive and verbal counting task while running. Repeated measures ANOVA indicated a significant interaction between feedback and training on PPA (F = 4.642; P = 0.048) but not vertical loading rates (F > 1.953; P > 0.067). Pairwise comparisons indicated a significantly lower PPA and vertical loading rates after gait retraining (P  0.68). Visual feedback after gait retraining reduced PPA and vertical loading rates during distracted running (P  0.36). Gait retraining is effective in lowering impact loading even when the runners are distracted. In dual-task situation, visual biofeedback provided beneficial influence on kinetics control after gait retraining.

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.

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.

Full Text Available Abstract Background Knowledge of patterns in cancer patients’ health care utilisation around the time of diagnosis may guide health care resource allocation and provide important insights into this groups’ demand for health care services. The health care need of patients with comorbid conditions far exceeds the oncology capacity and it is therefore important to elucidate the role of both primary and secondary care. The aim of this paper is to describe the use of health care services amongst incident cancer patients in Denmark one year before and one year after cancer diagnosis. Methods The present study is a national population-based case–control (1:10 registry study. All incident cancer patients (n = 127,210 diagnosed between 2001 and 2006 aged 40 years or older were identified in the Danish Cancer Registry. Data from national health registries were provided for all cancer patients and for 1,272,100 controls. Monthly consultation frequencies, monthly proportions of persons receiving health services and three-month incidence rate ratios for one year before and one year after the cancer diagnosis were calculated. Data were analysed separately for women and men. Results Three months before their diagnosis, cancer patients had twice as many general practitioner (GP consultations, ten to eleven times more diagnostic investigations and five times more hospital contacts than the reference population. The demand for GP services peaked one month before diagnosis, the demand for diagnostic investigations one month after diagnosis and the number of hospital contacts three months after diagnosis. The proportion of cancer patients receiving each of these three types of health services remained more than 10% above that of the reference population from two months before diagnosis until the end of the study period. Conclusions Cancer patients’ health service utilisation rose dramatically three months before their diagnosis. This increase applied to

The aim of this work was to predict the shape of the articular eminence in a patient with unilateral hypoplasia of the right mandibular ramus before and after distraction osteogenesis (DO). Using a patient-specific musculoskeletal model of the mandible the hypothesis that the observed differences in this patient in the left and right articular eminence inclinations were consistent with minimisation of joint loads was tested. Moreover, a prediction was made of the final shape of the articular eminence after DO when the expected remodelling has reached a steady state. The individual muscle forces and the average TMJ loading were computed for each combination of articular eminence angles both before and after DO. This exhaustive parameter study provides a full overview of average TMJ loading depending on the angles of the articular eminences. Before DO the parameter study resulted in different articular eminence inclinations between left and right sides consistent with patient data obtained from CT scans, indicating that in this patient the articular eminence shapes result from minimisation of joint loads. The simulation model predicts development of almost equal articular eminence shapes after DO. The same tendency was observed in cone beam CT scans (NewTom) of the patient taken 6.5 years after surgery.

Substantial minorities of smokers who planned to quit used e-cigarettes before and after a hospitalization, primarily to aid quitting, and despite receiving conventional cessation support post-discharge. However, e-cigarette use was intermittent and dual use with cigarettes was common. E-cigarette use was more common among smokers who relapsed soon after discharge and received less intensive cessation help. Funding The Helping HAND 2 trial was funded by NIH/NHLBI grant #R01-HL11821. AH is funded by British Heart Foundation 4-year PhD studentship at University College London. The funding organizations had no role in the design and conduct of the study; collection, management, analysis, and interpretation of the data; preparation, review, or approval of the manuscript; or decision to submit the manuscript for publication.

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.

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.

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.

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.
