Subjective health status is an increasingly important parameter to assess the effect of percutaneous coronary intervention (PCI) in clinical practice. Aim of this study was to determine medical and psychosocial predictors of poor subjective health status over a 10 years' post-PCI period. We included a series of consecutive PCI patients (n = 573) as part of the RESEARCH registry, a Dutch single-center retrospective cohort study. These patients completed the 36-item Short-Form Health Survey (SF-36) at baseline and 10 years post-PCI. We found 6 predictors of poor subjective health status 10 years post-PCI: SF-36 at baseline, age, previous PCI, obesity, acute myocardial infarction as indication for PCI, and diabetes mellitus (arranged from most to least numbers of sub domains). SF-36 scores at baseline, age, and previous PCI were significant predictors of subjective health status 10 years post-PCI. Specifically, the SF-36 score at baseline was an important predictor. Thus assessment of subjective health status at baseline is useful as an indicator to predict long-term subjective health status. Subjective health status becomes better by optimal medical treatment, cardiac rehabilitation and psychosocial support. This is the first study determining predictors of subjective health status 10 years post-PCI.

Passive muscle heating has been shown to reduce the drop in post-warm-up muscle temperature (Tm) by about 25% over 30 min, with concomitant sprint/power performance improvements. We sought to determine the role of leg blood flow in this cooling and whether optimising the heating procedure would further benefit post-warm-up T m maintenance. Ten male cyclists completed 15-min sprint-based warm-up followed by 30 min recovery. Vastus lateralis Tm (Tmvl) was measured at deep-, mid- and superficial-depths before and after the warm-up, and after the recovery period (POST-REC). During the recovery period, participants wore water-perfused trousers heated to 43 °C (WPT43) with either whole leg heating (WHOLE) or upper leg heating (UPPER), which was compared to heating with electrically heated trousers at 40 °C (ELEC40) and a non-heated control (CON). The blood flow cooling effect on Tmvl was studied comparing one leg with (BF) and without (NBF) blood flow. Warm-up exercise significantly increased Tmvl by ~3 °C at all depths. After the recovery period, BF Tmvl was lower (~0.3 °C) than NBF Tmvl at all measured depths, with no difference between WHOLE versus UPPER. WPT43 reduced the post-warm-up drop in deep-Tmvl (-0.12 °C ± 0.3 °C) compared to ELEC40 (-1.08 ± 0.4 °C) and CON (-1.3 ± 0.3 °C), whereas mid- and superficial-Tmvl even increased by 0.15 ± 0.3 and 1.1 ± 1.1 °C, respectively. Thigh blood flow contributes to the post-warm-up Tmvl decline. Optimising the external heating procedure and increasing heating temperature of only 3 °C successfully maintained and even increased T mvl, demonstrating that heating temperature is the major determinant of post-warm-up Tmvl cooling in this application.

Materials International Space Station Experiment-X (MISSE-X) is a proposed International Space Station (ISS) external platform for space environmental studies designed to advance the technology readiness of materials and devices critical for future space exploration. The MISSE-X platform will expand ISS utilization by providing experimenters with unprecedented low-cost space access and return on investment (ROI). As a follow-on to the highly successful MISSE series of ISS experiments, MISSE-X will provide advances over the original MISSE configurations including incorporation of plug-and-play experiments that will minimize return mass requirements in the post-Shuttle era, improved active sensing and monitoring of the ISS external environment for better characterization of environmental effects, and expansion of the MISSE-X user community through incorporation of new, customer-desired capabilities. MISSE-X will also foster interest in science, technology, engineering, and math (STEM) in primary and secondary schools through student collaboration and participation.1,2

External femoral derotation osteotomy (FDO) is an orthopaedic intervention to correct increased femoral anteversion and associated excessive internal hip rotation and internal foot progression during gait in children with cerebral palsy. The resulting functional issues may include clearance problems and hip abductor lever-arm dysfunction. The purpose of this study was to evaluate long-term gait outcomes of FDO. Twenty ambulatory patients (27 sides) with cerebral palsy who underwent pre-operative (P0) and a one year post-operative (P1) gait analysis as part of the standard of care had a second post-operative analysis (P2) approximately 11 years post-surgical intervention. Mean hip rotation in stance showed statistically significant decreases in internal rotation at P1 post-surgical intervention that were maintained long-term (mean hip rotation P0: 21±9, P1: 0±9 and P2: 6±12 degrees internal). Similar results were seen with mean foot progression (P0: 9±16 degrees internal, P1: 14±13 degrees external, P2: 13±16 degrees external). However, 2/27 sides (9%) showed a recurrence of internal hip rotation of >15° at the 11year follow-up. The reasons for this recurrence could include age, surgical location and ongoing disease process all of which need to be further examined. We conclude that FDO can show long-term kinematic and functional benefits when performed in the prepubescent child with cerebral palsy in comparison to the natural progression of of hip rotation in cerebral palsy.

To explore change in activity levels post-stroke. We measured activity levels using the activPAL™ in hospital and at 1, 2 and 3 years' post-stroke onset. Of the 74 participants (mean age 76 (SD 11), 39 men), 61 were assessed in hospital: 94% of time was spent in sitting/lying, 4% standing and 2% walking. Activity levels improved over time (complete cases n = 15); time spent sitting/lying decreased (p = 0.001); time spent standing, walking and number of steps increased (p = 0.001, p = 0.028 and p = 0.03, respectively). At year 3, 18% of time was spent in standing and 9% walking. Time spent upright correlated significantly with Barthel (r = 0.69 on admission, r = 0.68 on discharge, both p < 0.01) and functional ambulation category scores (r = 0.55 on admission, 0.63 on discharge, both p < 0.05); correlations remained significant at all assessment points. Depression (in hospital), left hemisphere infarction (Years 1-2), visual neglect (Year 2), poor mobility and balance (Years 1-3) correlated with poorer activity levels. People with stroke were inactive for the majority of time. Time spent upright improved significantly by 1 year post-stroke; improvements slowed down thereafter. Poor activity levels correlated with physical and psychological measures. Larger studies are indicated to identify predictors of activity levels. Implications for Rehabilitation Activity levels (measured using activPAL™ activity monitor), increased significantly by 1 year post-stroke but improvements slowed down at 2 and 3 years. People with stroke were inactive for the majority of their day in hospital and in the community. Poor activity levels correlated with physical and psychological measures. Larger studies are indicated to identify the most important predictors of activity levels.

Proper standardization of laboratory testing requires assessment of performance after the tests are performed, known as the post-analytical phase. A nationwide external quality assessment (EQA) scheme implemented in Croatia in 2014 includes a questionnaire on post-analytical practices, and the present study examined laboratory responses in order to identify current post-analytical phase practices and identify areas for improvement. In four EQA exercises between September 2014 and December 2015, 145-174 medical laboratories across Croatia were surveyed using the Module 11 questionnaire on the post-analytical phase of testing. Based on their responses, the laboratories were evaluated on four quality indicators: turnaround time (TAT), critical values, interpretative comments and procedures in the event of abnormal results. Results were presented as absolute numbers and percentages. Just over half of laboratories (56.3%) monitored TAT. Laboratories varied substantially in how they dealt with critical values. Most laboratories (65-97%) issued interpretative comments with test results. One third of medical laboratories (30.6-33.3%) issued abnormal test results without confirming them in additional testing. Our results suggest that the nationwide post-analytical EQA scheme launched in 2014 in Croatia has yet to be implemented to the full. To close the gaps between existing recommendations and laboratory practice, laboratory professionals should focus on ensuring that TAT is monitored and lists of critical values are established within laboratories. Professional bodies/institutions should focus on clarify and harmonized rules to standardized practices and applied for adding interpretative comments to laboratory test results and for dealing with abnormal test results.

To investigate external-cause mortality among 21 609 Norwegian male military peacekeepers deployed to Lebanon during 1978-1998. The cohort was followed from the 1st day of deployment through 2013, and mortality during deployment and post discharge was assessed using SMRs calculated from national rates in Norway. Poisson regression was used to see the effect of high-conflict versus low-conflict exposure. For the total cohort, external-cause mortality was within expected values during deployment (SMR=0.80) and post discharge (SMR=1.05). In the low-conflict exposure group, a lower mortality from all external causes (SMR=0.77), transport accidents (SMR=0.55) and accidental poisoning (SMR=0.53) was seen. The high-conflict exposure group showed an elevated mortality from all external causes (SMR=1.20), transport accidents (SMR=1.51) and suicide (SMR=1.30), but these risks were elevated only during the first 5 years after discharge. This group also showed elevated mortality from all external causes (rate ratio, RR=1.49), and for transport accidents (RR=3.30) when compared with the low-conflict exposure group. Overall external-cause mortality among our peacekeepers was equal to national rates during deployment and post discharge. High-conflict exposure was associated with elevated mortality from all external causes, transport accidents and suicide during the first 5 years after discharge from service. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

In upper brachial plexus palsy patients, loss of shoulder function and elbow flexion is obvious as the result of paralysed muscles innervated by the suprascapular, axillary and musculocutaneus nerve. Shoulder stabilisation, restoration of abduction and external rotation are important as more distal functions will be affected by the shoulder situation. Between 2005 and 2011, eleven patients with upper type brachial plexus palsy were operated on with triceps nerve branch transfer to anterior axillary nerve branch and spinal accessory nerve transfer to the suprascapular nerve for shoulder abduction and external rotation restoration. Nine patients met the inclusion criteria for the study. All patients were men with ages ranged from 21 to 35 years (average, 27.4 years). The interval between injury and surgery ranged from 4 to 11 months (average, 7.2 months). Atrophy of the supraspinatus, infraspinatus and deltoid muscle and subluxation at the glenohumeral joint was obvious in all patients preoperatively. During the pre-op examination all patients had at least muscle grading 4 on the triceps muscle. The mean post-operative value of shoulder abduction was 112.2° (range: 60-170°) while preoperatively none of the patients was able for abduction (p<0.001). The mean post-operative value of shoulder external rotation was 66° (range: 35-110°) while preoperatively none of them was able for external rotation (p<0.001). Postoperative values of shoulder abduction were significantly better that those of external rotation (p=0.0004). The postoperative average muscle grading for shoulder abduction according the MRC scale was 3.6±0.5 and for the shoulder external rotation was 3.2±0.4. Combined nerve transfer by using the spinal accessory nerve for suprascapular nerve neurotisation and one of the triceps nerve branches for axillary nerve and teres minor branch neurotisation is an excellent choice for shoulder abduction and external rotation restoration.

Delay-discounting, the tendency to prefer a smaller-sooner reward to a larger-later reward, has been associated with a range of externalizing behaviors. Laboratory delay-discounting tasks have emerged as a useful measure to index impulsivity and a proclivity towards externalizing pyschopathology. While many studies demonstrate the existence of a latent externalizing factor that is heritable, there have been few genetic studies of delay-discounting. Further, the increased vulnerability for risky behavior in adolescence makes adolescent samples an attractive target for future research, and expeditious, ecologically-valid delay-discounting measures are helpful in this regard. The primary goal of this study was to help validate the utility of a "cash-choice" measure for use in a sample of older adolescents. We used a sample of 17-year-old twins (n = 791) from the Minnesota Twin Family Enrichment study. Individuals who chose the smaller-sooner reward were more likely to have used a range of addictive substances, engaged in sexual intercourse, and earned lower GPAs. Best fitting biometric models from univariate analyses supported the heritability of cash-choice and externalizing, but bivariate modeling results indicated that the correlation between cash-choice and externalizing was determined largely by shared environmental influences, thus failing to support cash-choice as a possible endophenotype for externalizing in this age group. Our findings lend further support to the utility of cash-choice as a measure of individual differences in decision making and suggest that, by late adolescence, this task indexes shared environmental risk for externalizing behavior.

With the recent emphasis on evidence-based practice and healthcare reform, understanding the cost of dysphagia management has never been more important. It is helpful for clinicians to understand and objectively report the costs associated with dysphagia when they advocate for their services in this economy. Having carefully estimated cost of illness, inputs are needed for cost-effectiveness analyses that help support the value of treatments. This study sought to address this issue by examining the 1-year cost associated with a diagnosis of dysphagia post-stroke in South Carolina. Furthermore, this study investigated whether ethnicity and residence differences exist in the cost of dysphagia post-stroke. Data on 3,200 patients in the South Carolina Medicare database from 2004 who had ICD-9 codes for ischemic stroke, 434 and 436, were retrospectively included in this study. Differences between persons with and without dysphagia post-stroke were compared with respect to age, gender, ethnicity, mortality, length of stay, comorbidity, rurality, discharge disposition, and cost to Medicare. Univariate analyses and a gamma-distributed generalized linear multivariable model with a log link function were completed. We found that the 1-year cost to Medicare for persons with dysphagia post ischemic stroke was $4,510 higher than that for persons without dysphagia post ischemic stroke when controlling for age, comorbidities, ethnicity, and proportion of time alive. Univariate analysis revealed that rurality, ethnicity, and gender were not statistically significantly different in comparisons of individuals with or without dysphagia post-stroke. Post-stroke dysphagia significantly increases post-stroke medical expenses. Understanding the expenditures associated with post-stroke dysphagia is helpful for optimal allocation and use of resources. Such information is needed to conduct cost-effectiveness studies.

Objective Post-myocardial infarction (MI) care is crucial to preventing recurrent major adverse cardiovascular events (MACE), but can be complicated to personalise. A tool is needed that effectively stratifies risk of cardiovascular (CV) events 1–3 years after MI but is also clinically usable. Methods Patients surviving ≥1 year after an index MI with ≥1 risk factor for recurrent MI (ie, age ≥65 years, prior MI, multivessel coronary disease, diabetes, glomerular filtration rate <60 mL/min/1.73 m2) were studied. Cox regression derived sex-specific Intermountain Major Adverse Cardiovascular Events (IMACE) risk scores for the composite of 1-year to 3-year MACE (CV death, MI or stroke). Derivation was performed in 70% of subjects (n=1342 women; 3047 men), with validation in the other 30% (n=576 women; 1290 men). Secondary validations were also performed. Results In women, predictors of CV events were glucose, creatinine, haemoglobin, platelet count, red cell distribution width (RDW), age and B-type natriuretic peptide (BNP); among men, they were potassium, glucose, blood urea nitrogen, haematocrit, white blood cell count, RDW, mean platelet volume, age and BNP. In the primary validation, in women, IMACE ranged from 0 to 11 (maximum possible: 12) and had HR=1.44 per +1 score (95% CI 1.29 to 1.61; P<0.001); men had IMACE range 0–14 (maximum: 16) and HR=1.29 per +1 score (95% CI 1.20 to 1.38; P<0.001). IMACE ≥5 in women (≥6 in men) showed strikingly higher MACE risk. Conclusions Sex-specific risk scores strongly stratified 1-year to 3-year post-MI MACE risk. IMACE is an inexpensive, dynamic, electronically delivered tool for evaluating and better managing post-MI patient care. PMID:29531761

The bidirectional pathways between internalizing and externalizing problems and academic performance from 6 to 18 years.

Internalizing and externalizing problems are associated with poor academic performance, both concurrently and longitudinally. Important questions are whether problems precede academic performance or vice versa, whether both internalizing and externalizing are associated with academic problems when simultaneously tested, and whether associations and their direction depend on the informant providing information. These questions were addressed in a sample of 816 children who were assessed four times. The children were 6-10 years at baseline and 14-18 years at the last assessment. Parent-reported internalizing and externalizing problems and teacher-reported academic performance were tested in cross-lagged models to examine bidirectional paths between these constructs. These models were compared with cross-lagged models testing paths between teacher-reported internalizing and externalizing problems and parent-reported academic performance. Both final models revealed similar pathways from mostly externalizing problems to academic performance. No paths emerged from internalizing problems to academic performance. Moreover, paths from academic performance to internalizing and externalizing problems were only found when teachers reported on children's problems and not for parent-reported problems. Additional model tests revealed that paths were observed in both childhood and adolescence. Externalizing problems place children at increased risk of poor academic performance and should therefore be the target for interventions.

TNM-classification inadequately estimates patient-specific overall survival (OS). We aimed to improve this by developing a risk-prediction model for patients with advanced larynx cancer. Cohort study. We developed a risk prediction model to estimate the 5-year OS rate based on a cohort of 3,442 patients with T3T4N0N+M0 larynx cancer. The model was internally validated using bootstrapping samples and externally validated on patient data from five external centers (n = 770). The main outcome was performance of the model as tested by discrimination, calibration, and the ability to distinguish risk groups based on tertiles from the derivation dataset. The model performance was compared to a model based on T and N classification only. We included age, gender, T and N classification, and subsite as prognostic variables in the standard model. After external validation, the standard model had a significantly better fit than a model based on T and N classification alone (C statistic, 0.59 vs. 0.55, P < .001). The model was able to distinguish well among three risk groups based on tertiles of the risk score. Adding treatment modality to the model did not decrease the predictive power. As a post hoc analysis, we tested the added value of comorbidity as scored by American Society of Anesthesiologists score in a subsample, which increased the C statistic to 0.68. A risk prediction model for patients with advanced larynx cancer, consisting of readily available clinical variables, gives more accurate estimations of the estimated 5-year survival rate when compared to a model based on T and N classification alone. 2c.

Obesity is considered a public health problem and has led to advancements in bariatric surgery. Laparoscopic sleeve gastrectomy (LSG) had become the most performed procedure worldwide; however, its consequences on nutritional status in the short and long term are of concern. A retrospective analysis of medical records and bariatric database of patients who underwent LSG from October 2008-September 2015 at Al-Amiri Hospital, Kuwait, was performed. Data regarding nutritional status along with demographic data were collected over a 5-year follow-up period. One thousand seven hundred ninety-three patients comprising of 74% females and 26% males were included. The greatest % total body weight loss (%TBWL) was at 18 months post-LSG (33%), corresponding to a % excess weight loss (%EWL) of 73.8%. With regard to nutritional status, vitamin B1 showed a significant drop at 3-5 years post-op in comparison to pre-op value, but stayed within the normal range throughout the study. Red blood cells count, hemoglobin, and hematocrit also showed a significant drop starting from 6 months post-op until the fifth year of follow-up. On the other hand, vitamins B6 and B12 showed a significant increase at 6 months post-op and decreased afterwards, but did not reach pre-op values. Vitamin D also showed a significant increase throughout the study period from deficient value at the pre-op time, but remained insufficient. Albumin, transferrin, folate, ferritin, iron, and vitamin B2 showed no significant changes at 5 years post-LSG compared to pre-op values. Little is known about the nutritional status and optimal nutritional care plan post-LSG, especially in the longer term. Nutritional deficiencies were prevalent prior and post-LSG. Some of the nutritional parameters improved and even reached the abnormal high level post-LSG. These observations highlight the importance of pre- and post-operative nutritional assessment and tailored supplementation to ensure optimal nutritional status.

Objective This study examines parents' and children's exposure to short-term political violence and the relation between childrearing violence and child adjustment following widespread violence that erupted in Kisumu, Kenya after the disputed presidential election in December 2007. Method Mothers of 100 Luo children (mean age = 8.46 years, 61% female) reported on their own use of childrearing violence at Time 1, approximately 4 months after the disputed election, and again at Times 2 (n = 95) and 3 (n = 95), approximately 12 and 24 months later, respectively. At Time 2, mothers reported about post-election violence directed at them and about their children's exposure to post-election violence. Children reported about their own externalizing behaviors at Times 1, 2, and 3. Results Children's exposure to post-election violence was related to Time 2 externalizing behavior, and childrearing violence at Time 1 predicted child externalizing behavior at Time 2. Exposure to post-election violence was not directly related to either childrearing violence or children's externalizing behavior by Time 3, although children's externalizing at Time 2 predicted more childrearing violence at Time 3. Conclusion These results support earlier work that links childrearing violence and children's exposure to political violence with increases in child externalizing behavior, but examined these links in the under-studied area of short-term political violence. Even though sudden and severe political violence may subside significantly in weeks or months, increased attention to long-term effects on parenting and child adjustment is warranted. PMID:24639914

Some risk factors can have impacts on the cost, time, and performance. Results of previous studies indicated that the external conditions are among the factors which give effect to the contractor in the completion of the project. The analysis in the study carried out by considering the conditions of the project in the last 15 years in Aceh province, divided into military conflict phase (2000-2004), post tsunami disaster rehabilitation and reconstruction phase (2005-2009), and post-rehabilitation and reconstruction phase (2010-present). This study intended to analyze the impact of external risk factors, primarily related to the impact on project costs and to investigate the influence of the risk factors and construction phases impacted the project cost. Data was collected by using a questionnaire distributed in 15 large companies qualification contractors in Aceh province. Factors analyzed consisted of socio-political, government policies, natural disasters, and monetary conditions. Data were analyzed using statistical application of severity index to measure the level of risk impact. The analysis results presented the tendency of impact on cost can generally be classified as low. There is only one variable classified as high-impact, variable `fuel price increases', which appear on the military conflict and post tsunami disaster rehabilitation and reconstruction periods. The risk impact on costs from the factors and variables classified with high intensity needs a serious attention, especially when the high level impact is followed by the high frequency of occurrences.

Purpose To examine separate mediational models linking a) menarcheal status or b) pubertal timing to internalizing and externalizing problems through competence. Method Cross-sectional analyses of 262 adolescent girls (11–17 years; M=14.93, SD=2.17) enrolled in a longitudinal study examining the association of psychological functioning and smoking with reproductive and bone health. Measures of menarcheal status (pre/post), pubertal timing (early, on-time, or late), internalizing and externalizing behavior, and perceived competence (parent and adolescent report) were obtained. Structural Equation Modeling was used for analyses. Results Perceived competence was found to fully mediate the association between menarcheal status and parent report of internalizing and externalizing problems. For adolescent report, there was a full mediation effect for internalizing problems but a partial mediation effect for externalizing problems. Being menarcheal was related to lower competence which was related to higher internalizing and externalizing problems. Models including pubertal timing were not significant. Conclusions Perceived competence is important in understanding the associations between menarcheal status and internalizing and externalizing problems. Interventions targeting competence, particularly in post-menarcheal girls, may reduce or prevent problem behaviors. PMID:21939864

Investigation of whole-part and composite effects in 4- to 6-year-old children gave rise to claims that face perception is fully mature within the first decade of life (Crookes & McKone, 2009). However, only internal features were tested, and the role of external features was not addressed, although external features are highly relevant for holistic face perception (Sinha & Poggio, 1996; Axelrod & Yovel, 2010, 2011). In this study, 8- to 10-year-old children and adults performed a same-different matching task with faces and watches. In this task participants attended to either internal or external features. Holistic face perception was tested using a congruency paradigm, in which face and non-face stimuli either agreed or disagreed in both features (congruent contexts) or just in the attended ones (incongruent contexts). In both age groups, pronounced context congruency and inversion effects were found for faces, but not for watches. These findings indicate holistic feature integration for faces. While inversion effects were highly similar in both age groups, context congruency effects were stronger for children. Moreover, children's face matching performance was generally better when attending to external compared to internal features. Adults tended to perform better when attending to internal features. Our results indicate that both adults and 8- to 10-year-old children integrate external and internal facial features into holistic face representations. However, in children's face representations external features are much more relevant. These findings suggest that face perception is holistic but still not adult-like at the end of the first decade of life. Copyright © 2014 Elsevier B.V. All rights reserved.

We systematically quantified excess mortality in epilepsy patients by cause of death using the population-attributable fraction and epilepsy-attributable years of potential life lost (YPLL) by age 75 years at ages 15 and over. We updated and undertook a re-review of mortality studies from our previous systematic review following PRISMA guidelines to identify cohort studies of general epilepsy populations reporting a relative risk (RR) of death by cause relative to the background rates in the population. Studies on epilepsy prevalence were identified through published reviews. Country-specific mortality figures were obtained from the WHO World Mortality Database. We performed a pooled analysis with the DerSimonian-Laird random effects method. In countries with very high Human Development Indices, epilepsy contributed to 0.5-1.1 % of all deaths in the total population. Among external causes, suicides (RR 2.9, 95 % confidence interval 2.2-3.8; I(2) 52 %) were the major contributor to YPLL, corresponding to 6.7 % and 4.2 % of excess YPLL due to epilepsy in the United States (US) and in the United Kingdom (UK) in 2010, with 541 (346-792) and 44 (28-65) excess suicide cases, respectively. Fatal accidental falls were more common, with 813 (610-1064) and 95 (71-125) excess deaths in the US and in the UK, but these caused only 2.0 % of excess YPLL as they occurred in older age groups. Suicides were the most important external cause of death in epilepsy patients in terms of excess YPLL, whereas other external causes were either more common in older ages or caused less excess deaths.

During a one year post-stroke period of observation, the recovery trend in treated aphasic patients was characterized by general progression in communication skill. The most notable improvement occurred on a measure of everyday function with changes worthy of note on tasks of auditory comprehension and spontaneous word production. In the first 6 months post-stroke, the greatest gain occurred in aphasic patients classified as Fluent, and the least gain in Global aphasics. On the auditory comprehension task, however, improvement was noted in all aphasics regardless of type. In contrast, during the latter half of the first year post-stroke, Fluent aphasics showed least and Global aphasics the greatest improvement. In spite of their progress, Global aphasic patients remained considerably more impaired than the other groups. That the Global aphasics remained so impaired was expected, but the extent and temporal characteristics of their progress in communicating was unexpected.

Introduction: Distal radius fracture (DRF) is a common injury and various treatment modalities including open reduction and internal fixation (ORIF) with volar locking plate are available. More recently, a non-invasive external fixator has been used. Aims: To prospectively compare the use of a non-invasive external fixator with early dynamisation for DRF against ORIF with volar locking plate control group. Methods: Consecutive patients with closed DRF were included in a prospective case-controlled study. Patients were assigned to non-invasive external fixator or ORIF. Minimum follow-up was two years. Follow-up was at weeks 2, 4, 6, 8, 12, 26 and at one and two-year post-operatively. The outcome measures included demographic details, injury mechanism, AO fracture type, risk factors, body mass index (BMI), ulnar styloid fracture and dorsal comminution, radiographs, grip strength and DASH score. Results: Consecutive 50 patients were treated either with non-invasive external fixator (25/50) or with ORIF (25/50) and the mean age of the two groups was 53 years (SD 17.1) and 49 years (SD 19.5), respectively. Demographics were matched in two groups. In the non-invasive external fixator group, there were 10 AO Type-A, 5 Type-B and 10 Type-C fractures. The ORIF group included 8 Type-A, 6 Type-B and 11 Type-C fractures. The mean DASH score at three-months and one-year post-injury in non-invasive fixator group was 12.2 (SD 3.1) and 3.5 (SD 0.7), respectively, significantly greater than those of ORIF group 14.5 (SD 5.6) and 11.2 (SD 4.4), respectively (p < 0.05). Conclusion: DRF treated with non-invasive external fixator can give functional results superior to ORIF at three-months and the trend is maintained at one and two-year post-operatively.

Long-term role of external breast prostheses after total mastectomy.

PubMed

Glaus, Simone W; Carlson, Grant W

2009-01-01

After total mastectomy, many women choose to wear external breast prosthesis rather than undergo breast reconstruction. The purpose of this study was to evaluate long-term satisfaction among external breast prosthesis wearers and the impact of satisfaction on prosthesis use. A questionnaire was designed to assess demographic information, prosthesis information provision, prosthesis use, and satisfaction with prosthesis. Fifty-nine women who had undergone total mastectomy without breast reconstruction completed the questionnaire. The majority of women (68%) were at least 5 years out from mastectomy. Approximately half (49%) of the women had received information about breast prostheses prior to mastectomy; 29% received information from the surgeon performing the operation. Frequent and prolonged prosthesis use was prevalent with 64% of participants reporting prosthesis use all the time, 6-7 days/week. Participants showed high rates (83%) of overall satisfaction. However, women who wore their prosthesis out in public only were less satisfied than more frequent wearers (50% versus 89%, chi(2) = 8.83, d.f. = 1, alpha = 0.05). Satisfaction increased over time, as women who were greater than 5 years out from mastectomy were more satisfied than women less that 5 years post-mastectomy (90% versus 67%, chi(2) = 4.43, d.f. = 1, alpha = 0.05). The vast majority of women are satisfied with their external breast prosthesis several years after mastectomy. Most women used their prosthesis all the time and overall satisfaction contributed to higher levels of prosthesis use. Given the long-term importance of external breast prostheses for women who have undergone mastectomy, a greater effort to inform patients about external breast prostheses prior to surgery is needed.

Little has been published about the effectiveness of training postgraduate physiotherapy coursework students in research methods and evidence-based practice (EBP) theory. Graduate qualities in most universities include lifelong learning. Inclusion of EBP in post-graduate coursework students' training is one way for students to develop the knowledge and skills needed to implement current best evidence in their clinical practice after graduation, thereby facilitating lifelong learning. This paper reports on change in confidence and anxiety in knowledge of statistical terminology and concepts related to research design and EBP in eight consecutive years of post-graduate physiotherapy students at one Australian university. Pre-survey/post-survey instruments were administered to students in an intensive 3-week post-graduate course, which taught health research methods, biostatistics and EBP. This course was embedded into a post-graduate physiotherapy programme from 2007 to 2014. The organization and delivery of the course was based on best pedagogical evidence for effectively teaching adult physiotherapists. The course was first delivered each year in the programme, and no other course was delivered concurrently. There were significant improvements in confidence, significantly decreased anxiety and improvements in knowledge of statistical terminology and concepts related to research design and EBP, at course completion. Age, gender and country of origin were not confounders on learning outcomes, although there was a (non-significant) trend that years of practice negatively impacted on learning outcomes (p = 0.09). There was a greater improvement in confidence in statistical terminology than in concepts related to research design and EBP. An intensive teaching programme in health research methods and biostatistics and EBP, based on best practice adult physiotherapy learning principles, is effective immediately post-course, in decreasing anxiety and increasing

Nowadays, post-mortem computed tomography (PMCT) has become an integral part of Forensic practice. The purpose of the study was to determine PMCT impact on diagnosis of the cause of death within the context of the external examination of the body, when autopsy has, at first, not been requested. We reviewed the records of 145 cases for which unenhanced PMCT was performed in addition to the external examination of the body from January 2014 to July 2015 at the Institute of Forensic medicine in Strasbourg (France). We confronted final reports from forensic pathologist to the corresponding PMCT reports. Data were collected in a contingency table and the impact of PMCT on the final conclusions of the forensic pathologist was evaluated via a Chi 2 test. PMCT results significantly impact the final conclusions of forensic pathologist (p<0,001). In some cases, PMCT permits etiological diagnosis by revealing a cause of death hidden from external examination (mainly natural death) or by supporting the clinical findings of the forensic pathologist. In other cases (traumatic death), PMCT enables fast and exhaustive lesion assessment. Lastly, there are situations where PMCT may be ineffective (intoxication, hanging or some natural deaths). Performing PMCT within the context of the external examination of the body when autopsy has, at first, not been requested could bring significant benefits in diagnosing the cause of death. The impact of PMCT varies depending on the circumstances of death. Copyright © 2018 Elsevier B.V. All rights reserved.

Use of external ventriculostomy and intrathecal anti-fungal treatment in cerebral mucormycotic abscess.

Mucormycosis is an invasive fungal infection associated with a high mortality. Cerebral mucor abscesses can result secondary to rhinocerebral or hematogenous spread. Amphotericin B, posaconazole, and aggressive surgical resection are the hallmarks of treatment. While amphotericin is typically administered intravenously, less is known about the use of intrathecal amphotericin B. We describe a 42-year-old man who developed a cerebellar mucor abscess after undergoing hematopoietic stem cell transplant for the treatment of myelodysplastic syndrome. In the post-operative period he was admitted to the neurocritical care unit and received liposomal amphotericin B intravenously and through an external ventricular drain. This patient demonstrates that utilization of an external ventricular drain for intrathecal antifungal therapy in the post-operative period may warrant further study in patients with difficult to treat intracranial fungal abscesses.

To assess the survival rate of two different post systems after 5 years of service with a prospective randomized controlled trial. One hundred patients in need of a post were studied. Half of the patients received long glass fiber-reinforced posts, while the other half received long metal screw posts. The posts were assigned randomly. After at least 5 years (mean, 61.37 months), follow-ups were established. When a complication occurred prior to this recall, the type and time of the complication was documented. Statistical analysis was performed using the log-rank test and Kaplan-Meier analysis. Additionally, a Cox regression was performed to analyze risk factors. The survival rate of fiber-reinforced posts was 71.8%. In the metal screw post group, the survival rate was significantly lower, 50.0% (log-rank test, P = .026). Metal posts resulted more often in more unfavorable complications (eg, root fractures); consequently, more teeth (n = 17) had to be extracted. The Cox regression identified the following risk factors: position of the tooth (anterior vs posterior teeth), degree of coronal tooth destruction, and the post system (fiber-reinforced post vs metal screw post). Fiber-reinforced restorations loosened in several patients; in some of these cases (n = 6), patients did not notice this, leading to the extraction of teeth. Long metal screw posts should be used with great care in endodontically treated teeth. Besides the selection of the post system, other factors influence the survival of the restoration.

The external post-mortem examination, its deficient quality and possible causes have been the subject of numerous political and professional discussions. The external post-mortem examination is the basis for the decision whether further criminal investigations are required to clarify the cause of death. It is thus an essential instrument to ensure legal certainty. Before cremation, a second external post-mortem examination is performed by a public medical officer to make sure that errors of the first post-mortem are corrected. In the present study, cases were retrospectively analyzed in which a forensic autopsy had been ordered on the basis of the results of the post-mortem examination performed before cremation. The entries on the death certificate regarding the manner and cause of death were compared with the autopsy results. Between 1998 and 2007, 387 autopsies were ordered after external examination before cremation. In 55 cases (14.2%), the autopsy revealed a non-natural death, although a natural death had been attested on the death certificate. In descending order, a wrong manner of death was attested by clinicians, general practitioners and emergency physicians. With regard to the place where the first external post-mortem had been performed the lowest error rate was seen in nursing homes. Concerning the cause of death, discrepancies between the first post-mortem and autopsy were found in 59.4% of the cases. In this respect, general practitioners and clinicians were ranking first, whereas in nursing homes the cause of death was wrongly assessed in over 70% of cases. At present, the medical post-mortem does not meet the required quality standards, especially with regard to legal certainty. Determination of the cause of death on the basis of the external post-mortem examination is a challenging task even for the experienced medical examiner. As to the categorization of the manner of death it has to be stated that non-natural deaths are often not recognized or

After the 2011 Fukushima Daiichi nuclear power plant accident, little information has been available on individual doses from external exposure among residents living in radioactively contaminated areas near the nuclear plant; in the present study we evaluated yearly changes in the doses from external exposure after the accident and the effects of decontamination on external exposure. This study considered all children less than 16 years of age in Soma City, Fukushima who participated in annual voluntary external exposure screening programs during the five years after the accident (n = 5,363). In total, 14,405 screening results were collected. The median participant age was eight years. The geometric mean levels of annual additional doses from external exposure attributable to the Fukushima accident, decreased each year: 0.60 mSv (range: not detectable (ND)-4.29 mSv), 0.37 mSv (range: ND-3.61 mSv), 0.22 mSv (range: ND-1.44 mSv), 0.20 mSv (range: ND-1.87 mSv), and 0.17 mSv (range: ND-0.85 mSv) in 2011, 2012, 2013, 2014, and 2015, respectively. The proportion of residents with annual additional doses from external exposure of more than 1 mSv dropped from 15.6% in 2011 to zero in 2015. Doses from external exposure decreased more rapidly than those estimated from only physical decay, even in areas without decontamination (which were halved in 395 days from November 15, 2011), presumably due to the weathering effects. While the ratios of geometric mean doses immediately after decontamination to before were slightly lower than those during the same time in areas without decontamination, annual additional doses reduced by decontamination were small (0.04-0.24 mSv in the year of immediately after decontamination was completed). The results of this study showed that the levels of external exposure among Soma residents less than 16 years of age decreased during the five years after the Fukushima Daiichi nuclear power plant accident. Decontamination had only limited and

A typical meteorological year (TMY) represents the typical meteorological conditions over many years but still contains the short term fluctuations which are absent from long-term averaged data. Meteorological data were measured at the Experimental Station of Cajamar 'Las Palmerillas' (Cajamar Foundation) in Almeria, Spain, over 19 years at the meteorological station and in a reference greenhouse which is typical of those used in the region. The two sets of measurements were subjected to quality control analysis and then used to create TMY datasets using three different methodologies proposed in the literature. Three TMY datasets were generated for the external conditions and two for the greenhouse. They were assessed by using each as input to seven horticultural models and comparing the model results with those obtained by experiment in practical trials. In addition, the models were used with the meteorological data recorded during the trials. A scoring system was used to identify the best performing TMY in each application and then rank them in overall performance. The best methodology was that of Argiriou for both greenhouse and external conditions. The average relative errors between the seasonal values estimated using the 19-year dataset and those using the Argiriou greenhouse TMY were 2.2 % (reference evapotranspiration), -0.45 % (pepper crop transpiration), 3.4 % (pepper crop nitrogen uptake) and 0.8 % (green bean yield). The values obtained using the Argiriou external TMY were 1.8 % (greenhouse reference evapotranspiration), 0.6 % (external reference evapotranspiration), 4.7 % (greenhouse heat requirement) and 0.9 % (loquat harvest date). Using the models with the 19 individual years in the historical dataset showed that the year to year weather variability gave results which differed from the average values by ± 15 %. By comparison with results from other greenhouses it was shown that the greenhouse TMY is applicable to greenhouses which have a solar

The goal of this population-based study was to determine the impact of post-mastectomy radiation therapy on long-term overall survival (OS) of male patients with breast cancer. We investigated 20-year OS rates of 664 patients diagnosed with primary stage I-III breast cancer in former East Germany between 1970 and 1989. Patients had a radical mastectomy with axillary lymph node dissection without systemic adjuvant therapy. Median follow-up time was 26.2 years (range 19-38 years). 52.4% of the patients had post-mastectomy radiotherapy. Radiotherapy showed different effects in each stage group after 20 years. Whereas there was an OS trend for radiotherapy to harm patients with stage I disease (hazard ratio (HR) 1.45; 95% confidence interval (CI) 0.98-2.15; p = 0.065), radiotherapy showed no benefit in patients with stage II disease (HR 0.82; 95% CI 0.62-1.1; p = 0.15). There was a significant survival benefit for patients with stage III disease receiving radiotherapy (HR 0.60; 95% CI 0.41-0.88; p = 0.008). Post-mastectomy radiotherapy is associated with longer OS in male patients with stage III breast cancer. Male breast cancer patients at stages I and II do not seem to benefit from radiotherapy, but obsolete irradiation techniques might explain adverse long-term effects in earlier stages.

External causes of death are the third most common causes of death, after cardiovascular diseases and malignant neoplasms, in inhabitants of Poland. External causes of death pose the greatest threat to people aged 5-44, which results in a great number of years of life lost. The aim of the study is the analysis of years of life lost due to external causes of death among rural inhabitants in Poland, particularly due to traffic accidents and suicides. The study material included a database created on the basis of 2,100,785 certificates of rural inhabitants in Poland in the period 1999-2012. The SEYLL p (Standard Expected Years of Life Lost per living person) and the SEYLL d (per death) indices were used to determine years of life lost due to external causes of death. Joinpoint models were used to analyze time trends. In the period 1999-2012, 151,037 rural inhabitants died due to external causes, including 27.2% due to traffic accidents and 25.2% due to suicides. In 2012, the SEYLL p was 1,817 per 100,000 males and 298 per 100,000 females. Among males, suicides (SEYLL p = 633 years per 100,000) and traffic accidents (SEYLL p = 473 years per 100,000) contributed to the largest number of years of life lost. Among females, SEYLLp values were: 109 years due to traffic accidents and 69 years due to suicides (per 100,000). Among males, SEYLL p values started to decrease in 2008 at the average annual rate of 3.2%. In the group of females in the period 1999-2012, SEYLL p values were decreasing by 2.4% per year. The decreasing trend of the number of lost years of life due to external causes among rural inhabitants does not apply to suicides among men. The SEYLL p due to this group of causes has been steadily increasing since 1999. Analysis of the years of life lost focuses on the social and economic aspects of premature mortality due to external causes.

The geometric mean levels of annual additional doses from external exposure attributable to the Fukushima accident, decreased each year: 0.60 mSv (range: not detectable (ND)–4.29 mSv), 0.37 mSv (range: ND–3.61 mSv), 0.22 mSv (range: ND–1.44 mSv), 0.20 mSv (range: ND–1.87 mSv), and 0.17 mSv (range: ND–0.85 mSv) in 2011, 2012, 2013, 2014, and 2015, respectively. The proportion of residents with annual additional doses from external exposure of more than 1 mSv dropped from 15.6% in 2011 to zero in 2015. Doses from external exposure decreased more rapidly than those estimated from only physical decay, even in areas without decontamination (which were halved in 395 days from November 15, 2011), presumably due to the weathering effects. While the ratios of geometric mean doses immediately after decontamination to before were slightly lower than those during the same time in areas without decontamination, annual additional doses reduced by decontamination were small (0.04–0.24 mSv in the year of immediately after decontamination was completed). The results of this study showed that the levels of external exposure among Soma residents less than 16 years of age decreased during the five years after the Fukushima Daiichi nuclear power plant accident.

Few studies on suicidal ideation have been conducted in post-stroke patients in China. This national study examined suicidal ideation at 1-year post-stroke and explored its demographic and clinical correlates. A total of 1418 patients with ischemic stroke were included in 56 hospitals nationwide. Demographic, clinical characteristics and neuro-imaging information were collected with standardized instruments, including assessment of stroke severity, depression, cognitive impairment, stroke recurrence, physical disability and insomnia. Suicidal ideation was measured using item 3 of the Hamilton Rating Scale for Depression. The frequency of suicidal ideation in this study was 6.6%. Multivariate analyses revealed that disability (OR=2.07, 95% CI=1.09-3.05), stroke recurrence (OR=4.13, 95% CI=1.74-9.77) and insomnia early (OR=1.87, 95% CI=1.03-3.39), middle (OR=2.66, 95% CI=1.46-4.85) and late (OR=2.35, 95% CI=1.31-4.19) at the 1-year follow-up and post-stroke depression (OR=2.16, 95% CI=1.23-3.82) were significantly associated with post-stroke suicidal ideation. Post-stroke depression, disability, insomnia and stroke recurrence are possible risk factors of suicidal ideation that warrant attention in clinical practice. Copyright © 2016 Elsevier Inc.

Post-silking Factor Consequences for N Efficiency Changes Over 38 Years of Commercial Maize Hybrids.

PubMed

Chen, Keru; Vyn, Tony J

2017-01-01

Hybrid selection in maize ( Zea mays L.) over the decades has increased post-silking dry matter (PostDM) and nitrogen (PostN) accumulation, often with an accompanying increase in one or more N use efficiency (NUE) metrics such as partial factor productivity (PFP), N conversion efficiency (NCE), and N internal efficiency (NIE). More certainty on the underlying mechanisms of how PostDM and PostN changes over time have contributed to NUE gains or losses in modern-era hybrids can only be realized by directly comparing hybrids of different eras in the context of production-system-relevant management systems. A two-year and two-location field study was conducted in Indiana with two N rates (55 and 220 kg N ha -1 ), three plant densities (54,000, 79,000, and 104,000 plants ha -1 ) and eight commercial hybrids that were released by a single seed company from 1967 to 2005. The main treatment effects of N rate, density, and hybrid dominated the PostDM and PostN responses, and there were no significant two-way or three-way interactions. Total dry matter at maturity gains averaged 80 kg ha -1 year -1 of hybrid release when averaged over locations, plant densities and N rates. Total N contents at maturity increased 0.68 kg ha -1 year -1 , primarily due to annual increases in grain N content (0.8 kg ha -1 year -1 ). Post-silking N uptake rate increased 0.44 kg ha -1 year -1 for these era hybrids in more favorable production site-years. Slopes of grain N concentration increases per unit PostN gain were similar for all hybrids. Gains in average PFP over time were considerably higher at the low N rate (0.9 kg ha -1 year -1 ) than at the high N rate (0.3 kg kg -1 year -1 ). Hybrid gains in NIE were evident from 1967 to 1994, but not thereafter. The low N rate and higher plant densities also increased relative NIE and NCE values, but without hybrid interactions. There was no consistent trend of NIE or NCE gains in these hybrids primarily because grain and whole-plant N concentrations

Contribution of family violence to the intergenerational transmission of externalizing behavior.

Ehrensaft, Miriam K; Cohen, Patricia

Research finds that early antisocial behavior is a risk for later intimate partner violence (IPV) perpetration and victimization, and that children's exposure to their parents' IPV is a risk for subsequent behavior problems. This study tests whether intimate violence (IPV) between partners contributes independently to the intergenerational transmission of antisocial behavior, using the Children in the Community Study, a representative sample (N = 821) followed for over 25 years in 6 assessments. The present study includes a subsample of parents (N = 678) and their offspring (N = 396). We test the role of three mechanisms by which IPV may influence child antisocial behavior-parental psychopathology, parenting practices, and child self-regulation. Results suggest that IPV independently increased the risk for offspring externalizing problems, net of the effects of parental history of antisocial behavior and family violence. IPV also increased the risk for parental post traumatic stress disorder (PTSD) and alcohol use disorder 2 years later, but not for major depressive disorder. Alcohol use disorder independently increased the risk for offspring externalizing behavior, but IPV continued to predict offspring externalizing net of parental alcohol use. Parenting, particularly low satisfaction with the child, was significantly associated with both IPV and externalizing behavior, but did not mediate the effects of IPV on externalizing. IPV predicted higher levels of emotional expressivity, aggression and hostile reactivity, and depressive mood in offspring. Implications for future research and prevention are discussed.

Objective: To discuss the clinical application and effects of domestic external fixator in the treatment of patients with malformations of limbs. Methods: A total of 7 289 patients with malformation of limbs who had been operated in Qin Sihe orthopedic surgery team from January 1989 to June 2016 were retrospective analyzed. The patients were treated with domestic external fixator, including 4 033 males and 3 256 females, aging from 2 to 82 years with a mean age of 23.4 years. There were 2 732 patients using Ilizarov external fixator, 4 713 patients using hybrid external fixator, 57 patients using monobrachial external fixator, 232 patients using Ilizarov external fixator and hybrid external fixator. The Ilizarov, hybrid and monobrachial external fixator were used in 67, 65 and 0 patients on the upper limbs and in 2 665, 4 616 and 57 patients on the lower limbs. There were 3 028 patients operated on the left limbs, 3 260 patients operated on the right limbs and 1 001 patients operated on the bilateral limbs. The top three types of diseases were sequelae of poliomyelitis, cerebral palsy and post-traumatic stress disorder peromely. Deformity types inclued talipes equinovarus, knee flexion deformity, cavus foot and so on. Results: All the patients were followed up for a period of 2.5 months to 22.4 years, with an average follow-up time of 5.4 years. All of the external fixators were used for single once, and there was no substitute for external fixator quality problem. All the patients were completed surgery goal until removing external fixation except 1 patient gave up treatment and 1 removed the fixator because of metal allergy. The common complications included wire or pin infection and joint movement limitation and so on. Conclusions: The domestic external fixator developed and produced based on the characteristics of Chinese limb deformity disability. The domestic external fixator can be used to treat kinds of limb deformities with the advantages of practical

In 1985, external quality assurance was initiated in the Netherlands to reduce the between-laboratory variability of leukemia/lymphoma immunophenotyping and to improve diagnostic conclusions. This program consisted of regular distributions of test samples followed by biannual plenary participant meetings in which results were presented and discussed. A scoring system was developed in which the quality of results was rated by systematically reviewing the pre-analytical, analytical, and post-analytical assay stages using three scores, i.e., correct (A), minor fault (B), and major fault (C). Here, we report on 90 consecutive samples distributed to 40-61 participating laboratories between 1998 and 2012. Most samples contained >20% aberrant cells, mainly selected from mature lymphoid malignancies (B or T cell) and acute leukemias (myeloid or lymphoblastic). In 2002, minimally required monoclonal antibody (mAb) panels were introduced, whilst methodological guidelines for all three assay stages were implemented. Retrospectively, we divided the study into subsequent periods of 4 ("initial"), 4 ("learning"), and 7 years ("consolidation") to detect "learning effects." Uni- and multivariate models showed that analytical performance declined since 2002, but that post-analytical performance improved during the entire period. These results emphasized the need to improve technical aspects of the assay, and reflected improved interpretational skills of the participants. A strong effect of participant affiliation in all three assay stages was observed: laboratories in academic and large peripheral hospitals performed significantly better than those in small hospitals. © 2015 International Clinical Cytometry Society. © 2015 International Clinical Cytometry Society.

Persistence of external signs in Pacific herring Clupea pallasii Valenciennes with ichthyophoniasis

Hart, Lucas M.; Conway, Carla M.; Elliott, Diane G.; Hershberger, Paul K.

2016-01-01

The progression of external signs of Ichthyophonus infection in Pacific herring Clupea pallasii Valenciennes was highly variable and asynchronous after intraperitoneal injection with pure parasite preparations; however, external signs generally persisted through the end of the study (429 days post-exposure). Observed signs included papules, erosions and ulcers. The prevalence of external signs plateaued 35 days post-exposure and persisted in 73–79% of exposed individuals through the end of the first experiment (147 days post-exposure). Among a second group of infected herring, external signs completely resolved in only 10% of the fish after 429 days. The onset of mortality preceded the appearance of external signs. Histological examination of infected skin and skeletal muscle tissues indicated an apparent affinity of the parasite for host red muscle. Host responses consisted primarily of granulomatous inflammation, fibrosis and necrosis in the skeletal muscle and other tissues. The persistence and asynchrony of external signs and host response indicated that they were neither a precursor to host mortality nor did they provide reliable metrics for hindcasting on the date of exposure. However, the long-term persistence of clinical signs in Pacific herring may be useful in ascertaining the population-level impacts of ichthyophoniasis in regularly observed populations.

Periprosthetic bleeding 18 years post-silicone reconstruction of the orbital floor.

2011-10-01

Periprosthetic orbital haemorrhage is an uncommon complication of the alloplastic implants used in post-traumatic orbital floor repair. The small case series or individual reports provide no definite causative explanation for this delayed bleeding around silicone implants. It is likely that it is related to the disruption of fine capillaries within the pseudocapsule surrounding the implant, since the material does cause low-grade irritation with evidence of chronic inflammation. We report the case of a patient who developed a spontaneous periprosthetic bleeding 18 years' post-silicone sheet reconstruction of the orbital floor. Urgent removal of the implant insured prompt resolution of all symptoms and no further problem during the 2-year follow-up. This report emphasizes that periprosthetic orbital haemorrhage can occur years after the initial repair. Awareness of this rare complication allows for prompt diagnosis, decreasing the possibility of permanent damage of the orbital content. The removal of implant is necessary to relieve the symptoms and prevent potential infective complications.

2011-01-01

In this article, we present 3 cases of patients with different types of haemorrhoidal disease. The first patient is a 27-year-old woman who had been experiencing incidental rectal blood loss without pain during defecation for 3 months. The second patient is a 76-year-old woman who had been bothered by varying degrees of pain from a swelling nearby the anus for 1 year. The third case involves a 31-year-old man who had had continuous severe pain in the anal area for 3 consecutive days. The first patient appeared to have internal hemorrhoids, whereas different forms of external hemorrhoids affected the patients in the other 2 cases. Internal haemorrhoids develop from the intraluminal corpus cavernosum recti; external haemorrhoids from the perianal marginal veins. Patients with internal haemorrhoids present with symptoms that include blood loss and prolaps feeling during defecation. In patients with external haemorrhoids pain is the prominent symptom. Internal haemorrhoids are treated either conservatively or surgically, depending upon their severity. Considering external haemorrhoidal disease surgical treatment provides the most rapid and persistent relief of symptoms.

Acne vulgaris commonly affects adolescents. But recent reports suggest a rising prevalence of post-adolescence acne. While there are few reports on post-adolescence acne, there are even fewer reports comparing adolescence acne and post-adolescence. Epidemiological data of adolescence (<25 years) and post-adolescence (≥25 years) acne patients diagnosed between 2004 and 2013 in a tertiary dermatology referral centre was analysed. From the pool of patients seen in 2010, 80 adolescence and 84 post-adolescence acne patients' epidemiological characteristics and treatment responses were analysed. During the 10-year study period, there was an increase in the number and proportion of acne cases. In 2004, 4447 (5.77%) of all new diagnoses made were of acne vulgaris. The proportion rose to 5723 (8.13%) in 2013. There were consistently more female than male acne patients. The proportion of post-adolescent cases remained constant at about 30% of all acne patients seen. Mean age of acne vulgaris patients decreased from 23.1 years in 2004 to 22.6 years in 2013. In the subgroup analysis, there were more males than females with adolescence acne (61.3% vs. 38.8%, P < 0.01) and more females with post-adolescence acne (69.0% vs. 31.0%, P < 0.01). Thirty-four (40.5%) post-adolescence acne patients had acne from adolescence persisting into adulthood. Comedonal acne was more prevalent in the adolescence acne patients (58.8% vs. 40.5%, P = 0.019), whereas cystic acne was more prevalent in post-adolescence patients (18.1% vs. 7.5%, P = 0.044). Systemic retinoids were more often used for treatment in the adolescence acne patients than post-adolescence acne patients (23.8% vs. 10.7%, P = 0.027). Acne predominantly affects adolescents but post-adolescence acne is not uncommon. For post-adolescence acne, females predominate over males. Inflammatory and cystic acne tends to be more predominant in post-adolescence acne patients, whereas comedonal acne is more often seen in adolescence acne

The purpose of the present investigation was to evaluate the contribution of age-at-insult and brain pathology on longitudinal outcome and recovery of pragmatic language in a sample of children and adolescents with traumatic brain injury (TBI). Children and adolescents with mild to severe TBI (n=112) were categorized according to timing of brain insult: (i) Middle Childhood (5-9 years; n=41); (ii) Late Childhood (10-11 years; n=39); and (iii) Adolescence (12-15 years; n=32) and group-matched for age, gender and socio-economic status (SES) to a typically developing (TD) control group (n=43). Participants underwent magnetic resonance imaging (MRI) including a susceptibility weighted imaging (SWI) sequence 2-8 weeks after injury and were assessed on measures of pragmatic language and behavioural functioning at 6- and 24-months after injury. Children and adolescents with TBI of all severity levels demonstrated impairments in these domains at 6-months injury before returning to age-expected levels at 2-years post-TBI. However, while adolescent TBI was associated with post-acute disruption to skills that preceded recovery to age-expected levels by 2-years post injury, the middle childhood TBI group demonstrated impairments at 6-months post-injury that were maintained at 2-year follow up. Reduced pragmatic communication was associated with frontal, temporal and corpus callosum lesions, as well as more frequent externalizing behaviour at 24-months post injury. Findings show that persisting pragmatic language impairment after pediatric TBI is related to younger age at brain insult, as well as microhemorrhagic pathology in brain regions that contribute to the anatomically distributed social brain network. Relationships between reduced pragmatic communication and more frequent externalizing behavior underscore the need for context-sensitive rehabilitation programs that aim to increase interpersonal effectiveness and reduce risk for maladaptive behavior trajectories into the

Fatal injury surveillance data provide an opportunity to assess the impact of occupational injuries and may indicate which industries or occupations are appreciably more hazardous than others, and thus should be given priority in public health intervention. Fatalities from the National Traumatic Occupational Fatality surveillance system served as the basis for examining external cause (E-code) specific impact summaries. Years of potential life lost (YPLL) were calculated for fatal injuries in the years 1983-1994. Industries and occupations were compared with respect to frequency of fatal injuries. In addition, injuries in categories of external causes are examined across all industries and occupations. Machinery, electric current, homicide, falls, and transportation-related are the external cause groups highlighted by high frequency/rate of occurrence. Electric current event groups are also characterized by high average YPLL. Poisoning, conflagration, and lightning were also identified in several occupations as having high associated average YPLL. The external-cause-specific analysis of average YPLL identified industries and occupations where, on average, younger workers were dying in fatal injuries. Noteworthy in this assessment were homicides and falls. The YPLL measure coupled with more commonly employed indices (e.g., rates) may provide a fuller description of the impact of occupational fatal injuries.

Long-term follow-up and risk factors of persistent post-partum depression (PPD) are fairly unknown compared with its prevalence in the developing countries. In this study, we did a follow-up measure of PPD and examined the factors, which were associated with PPD 1-year post-partum. Our sample comprised of 34 women. Depressive symptoms were assessed by the Edinburgh post-natal depression scale (EPDS) 6 weeks post-partum, and women with scores >12 on this scale was categorised as depressed. Personality disorders were determined at the same occasion by means of the Structured Clinical Interview for DSM-III-R personality disorders (SCID-II). One year post-partum EPDS was completed. The rate of PPD 1-year post-partum was 32.4%, and it was unrelated to age at assessment, primiparity, number of children, employment status, economical status and educational level. Women depressed 1-year post-partum had significantly higher basal scores of EPDS and more often also a diagnosis of any axis II disorder; and specifically dependent and obsessive-compulsive personality disorders. In our sample, the predictors of 1-year post-partum PPD were having higher basal score of EPDS and the existence of a personality disorder. This study suggests that women with PPD, scoring high in the EPDS scale 6 weeks post-partum and having a personality disorder, run a higher risk for depression at 1-year follow-up.

Purpose To assess changes in inmates’ misuse of substances from pre- to post-incarceration. Methods In Study 1, professionals (n = 162) and laypersons (n = 50) predicted how jail inmates’ substance misuse would change from pre-incarceration to post-release. In Study 2, a longitudinal study of 305 jail inmates, we examined actual changes in substance use and dependence from pre-incarceration to the first year post-incarceration, as well as whether changes varied as a function of demographic, criminal justice, treatment, and personality factors. Results Professionals and laypersons predicted little change in substance misuse whereas, in fact, inmates’ frequency of substance use and dependence decreased substantially from pre-incarceration to post-release. Sharper decreases were observed for inmates who were female, younger, more educated, serving longer sentences, enrolled in substance abuse treatment, high in shame-proneness, and low in criminogenic thinking. Race, first time incarceration, transfer to other correctional facilities, mandated community supervision (probation), and guilt-proneness did not predict changes in substance use or dependence. Conclusions Although substance misuse decreased, this remains a population high in need of substance abuse treatment both upon arrest and at one year post-incarceration; 60% of former inmates met at least one DSM-IV criterion for substance dependence at one year post-release.

The purpose of this study was to determine the effects of internal and external visual imagery perspectives on performance accuracy of open and closed tennis skills (i.e., serve, forehand, and backhand) among novices. Thirty-six young male novices, aged 15-18 years, from a summer tennis program participated. Following initial skill acquisition (12 sessions), baseline assessments of imagery ability and imagery perspective preference were used to assign participants to one of three groups: internal imagery ( n = 12), external imagery ( n = 12), or a no-imagery (mental math exercise) control group ( n = 12). The experimental interventions of 15 minutes of mental imagery (internal or external) or mental math exercises followed by 15 minutes of physical practice were held three times a week for six weeks. The performance accuracy of the groups on the serve, forehand, and backhand strokes was measured at pre- and post-test using videotaping. Results showed significant increases in the performance accuracy of all three tennis strokes in all three groups, but serve accuracy in the internal imagery group and forehand accuracy in the external imagery group showed greater improvements, while backhand accuracy was similarly improved in all three groups. These findings highlight differential efficacy of internal and external visual imagery for performance improvement on complex sport skills in early stage motor learning.

Research on twin-singleton differences in externalizing and internalizing problems in childhood is largely cross-sectional and yields contrasting results. The goal of this study was to compare developmental trajectories of externalizing and internalizing problems in 6- to 12-year-old twins and singletons. Child Behavior Checklist (CBCL) maternal reports of externalizing and internalizing problems were obtained for a sample of 9651 twins from the Netherlands Twin Register and for a representative general population sample of 1351 singletons. Latent growth modeling was applied to estimate growth curves for twins and singletons. Twin-singleton differences in the intercepts and slopes of the growth curves were examined. The developmental trajectories of externalizing problems showed a linear decrease over time, and were not significantly different for twins and singletons. Internalizing problems seem to develop similarly for twins and singletons up to age 9. After this age twins' internalizing symptoms start to decrease in comparison to those of singletons, resulting in less internalizing problems than singletons by the age of 12 years. Our findings confirm the generalizability of twin studies to singleton populations with regard to externalizing problems in middle and late childhood. The generalizability of studies on internalizing problems in early adolescence in twin samples should be addressed with care. Twinship may be a protective factor in the development of internalizing problems during early adolescence.

Obesity and a reduced physical activity are global developments. Physical activity affects the external skeletal robustness which decreased in German children. It was assumed that the negative trend of decreased external skeletal robustness can be found in other countries. Therefore anthropometric data of Russian and German children from the years 2000 and 2010 were compared. Russian (2000/2010 n = 1023/268) and German (2000/2010 n = 2103/1750) children aged 6-10 years were investigated. Height, BMI and external skeletal robustness (Frame-Index) were examined and compared for the years and the countries. Statistical analysis was performed by Mann-Whitney-Test. Comparison 2010 and 2000: In Russian children BMI was significantly higher; boys were significantly taller and exhibited a decreased Frame-Index (p = .002) in 2010. German boys showed significantly higher BMI in 2010. In both sexes Frame-Index (p = .001) was reduced in 2010. Comparison Russian and German children in 2000: BMI, height and Frame-Index were different between Russian and German children. German children were significantly taller but exhibited a lower Frame-Index (p<.001). Even German girls showed a significantly higher BMI. Comparison Russian and German children in 2010: BMI and Frame-Index were different. Russian children displayed a higher Frame-Index (p<.001) compared with Germans. In Russian children BMI has increased in recent years. Frame-Index is still higher in Russian children compared with Germans however in Russian boys Frame-Index is reduced. This trend and the physical activity should be observed in the future.

To study the success rate, predictors for success, and pregnancy outcomes after external cephalic version. Historical cohort study. Regional hospital, Hong Kong. All women who had singleton term breech pregnancies at term and opted for external cephalic version during 2001 and 2009. Their demographic data, clinical and ultrasound findings, procedure details, complications, and delivery outcomes were analysed. Predictive factors for successful external cephalic version. A total of 209 external cephalic versions were performed during the 9-year period. The success rate was 63% (75% for multiparous and 53% for nulliparous women). There was no significant complication. On univariate analysis, predictors of successful external cephalic version were: multiparity, unengaged presenting part, higher amniotic fluid index (≥ 10 cm), thin abdominal wall, low uterine tone, and easily palpable fetal head (subjective assessment by practitioners before external cephalic version). On multivariate analysis, only multiparity, non-engagement of the fetal buttock and thin maternal abdomen were associated with successful external cephalic version. In all, 69% of those who had successful external cephalic version succeeded in the first roll (P<0.001), and 82% of the women with successful external cephalic versions had vaginal deliveries (93% in multiparous and 69% in nulliparous women). Uptake rate of external cephalic version was studied in the latter part of the study period (2006-2009). Whilst 735 women were eligible for external cephalic version, 131 women chose to have the procedure resulting in an uptake rate of 18%. External cephalic version was effective in reducing breech presentations at term and corresponding caesarean section rates, but the uptake rate was low. Further work should address the barriers to the low acceptance of external cephalic version. The results of this study could encourage women to opt for external cephalic version.

On 26 December 2004, 280 000 people lost their lives in the Asia-Pacific region. A massive earthquake struck Indonesia, triggering a tsunami that affected several countries, including Thailand. This tsunami had important implications for the health status of Thai citizens and health planning, and thus there is a need to study its long-term impact. This cohort study identified determinants of health service utilization (outpatient services, inpatient services, home care, medications and informal care) 1 and 2 years post-tsunami in Thailand. A two-part model with a multivariate logistic regression for each part was used to identify determinants of the propensity and intensity of utilization. Of 1943 participants, 1889 (97.2%) participated at 1 year and 1814/1889 (96.0%) at 2 years. Common determinants of health service utilization in post-tsunami settings were age, marital status, education level, employment status, number of health conditions and (physical and mental) health status. Knowing the determinants of health service use, health providers may be able to establish programmes for, or to carefully monitor populations, who are more likely to use services. The study results may be used to inform requests for health resources or to assist the development of guidelines for long-term disaster recovery planning.

Background. Hip distraction in Perthes' disease unloads the joint, which negates the harmful effect of the stresses on the articular surfaces, which may promote the sound healing of the area of necrosis. We have examined the effect of arthrodiastasis on the preservation of the femoral head in older children with Perthes' disease. Methods and Materials. Twelve children with age more than 8 years with Perthes' disease of less than one year were treated with hip distraction by a hinged monolateral external fixator. Observation and Results. Mean duration of distraction was 13.9 days. These children were evaluated by clinicoradiological parameters for a mean period of 32.4 months. There was a significant improvement in the range of movements and mean epiphyseal index, but the change in the percentage of uncovered head femur was insignificant. There was significant improvement in Harris Hip score. Conclusions. Hip distraction by hinged monolateral external fixator seems to be a valid treatment option in cases with Perthes' disease in the selected group of patients, where poor results are expected from conventional treatment.

The aim of this study was to compare the fracture of implant component behavior of external and internal type of implants to suggest directions for successful implant treatment. Data were collected from the clinical records of all patients who received WARANTEC implants at Seoul National University Dental Hospital from February 2002 to January 2014 for 12 years. Total number of implants was 1,289 and an average of 3.2 implants was installed per patient. Information about abutment connection type, implant locations, platform sizes was collected with presence of implant component fractures and their managements. SPSS statistics software (version 24.0, IBM) was used for the statistical analysis. Overall fracture was significantly more frequent in internal type. The most frequently fractured component was abutment in internal type implants, and screw fracture occurred most frequently in external type. Analyzing by fractured components, screw fracture was the most frequent in the maxillary anterior region and the most abutment fracture occurred in the maxillary posterior region and screw fractures occurred more frequently in NP (narrow platform) and abutment fractures occurred more frequently in RP (regular platform). In external type, screw fracture occurred most frequently, especially in the maxillary anterior region, and in internal type, abutment fracture occurred frequently in the posterior region. placement of an external type implant rather than an internal type is recommended for the posterior region where abutment fractures frequently occur.

This study explored pathways through which hurricane-related stressors affected the psychological functioning of elementary school aged children who survived Hurricane Katrina. Participants included 184 mothers from the New Orleans area who completed assessments one year pre-disaster (Time 1), and one and three years post-disaster (Time 2 and Time 3, respectively). Mothers rated their children's behavior problems at Time 3 only ( n = 251 children; 53.0% male; Mean age: 10.19 years, SD = 1.68 years). A path analytic model indicated that hurricane-related stressors were associated with increased maternal psychological distress and school mobility in the first post-disaster year, which were associated with higher child internalizing and externalizing symptoms three years post-disaster. Mediation analysis indicated that hurricane-related stressors were associated with child symptoms indirectly, through their impact on maternal psychological distress. Findings underscore the importance of interventions that boost maternal and child mental health and support children through post-disaster school transitions.

Change in physical mobility over 10 years in post-polio syndrome.

Bickerstaffe, A; Beelen, A; Nollet, F

2015-03-01

Post-polio syndrome is characterised by progressive muscle weakness and other symptoms which can limit physical mobility. We assessed the rate of decline in mobility over 10 years in relation to strength decline; and investigated potential predictors for the rate of decline of walking capacity, a measure of mobility, in 48 patients with post-polio syndrome and proven quadriceps dysfunction at baseline. Average walking capacity and self-reported physical mobility declined over 10 years, by 6 and 14%, respectively. Concomitantly people lost an average of 15% of isometric quadriceps strength. Significantly more people used walking aids offering greater support at follow-up. Notably, there was much individual variation, with 18% of participants losing a substantial amount of walking capacity (27% decline) and concomitant self-reported physical mobility (38% decline). Loss of quadriceps strength only explained a small proportion of the variance of the decline in walking capacity (R = 11%) and the rate of decline could not be predicted from baseline values for strength, walking capacity, self-reported physical mobility or basic demographics. The individual variability, yet lack of predictive factors, underscores the need for personally tailored care based on actual functional decline in patients with post-polio syndrome.

Background Zoster vaccine is a single dose live, attenuated vaccine (ZVL) indicated for individuals ≥50 years-old for the prevention of herpes zoster (HZ). Safety data from clinical trials and post-licensure studies provided reassurance that ZVL is generally safe and well tolerated. The objective of this review was to provide worldwide post-marketing safety information following 10 years of use and >34 million doses distributed. Methods All post-marketing adverse experience (AE) reports received worldwide between 02-May-2006 and 01-May-2016 from healthcare professionals following vaccination with ZVL and submitted to the MSD AE global safety database, were analyzed. Results A total of 23,556 AE reports, 93% non-serious, were reported. Local injection site reactions (ISRs), with a median time-to-onset of 2 days, were the most frequently reported AEs followed by HZ. The majority of HZ reports were reported within 2 weeks of vaccination and considered, based on time-to-onset, pathogenesis of HZ, and data from clinical trials, to be caused by wild-type varicella-zoster virus (VZV). HZ confirmed by PCR analysis to be VZV Oka/Merck vaccine-strain was identified in an immunocompetent individual 8 months postvaccination and in 4 immunocompromised individuals. Disseminated HZ was reported very rarely (<1%) with 38% occurring in immunocompromised individuals. All reports of disseminated HZ confirmed by PCR as VZV Oka/Merck vaccine-strain were in individuals with immunosuppressive conditions and/or therapy at the time of vaccination. Conclusions The safety profile of ZVL, following 10 years of post-marketing use, was favorable and consistent with that observed in clinical trials and post-licensure studies. PMID:29174682

Bone marrow macroscopic examination remains one of the most difficult and subjective laboratory assessments in hematology. Only a few external quality assurance programs in the field are present worldwide. We have developed an external quality assurance program EQAhem that allows assessment of the whole process of bone marrow examination. The program participants assess blood and bone marrow smears from the patient, identify selected cells from photographs provided to them, and interpret the microscopic results. In this article, the results of the EQAhem program in Poland from 6 years are summarized. During this time, 62 labs were assessed in total, and positive results were achieved by 89.25 % labs, taking into account all tests. Correct responses with respect to the percentage of cell count were provided by ca. 77.5 % labs. Slightly worse results were obtained when megakaryocyte count and cell identification from photographs were tested. The worst results were obtained in case of dysplasia assessment and clinical interpretation of microscopic examination (54.1 and 58.6 % correct responses, respectively). EQAhem delivers precise information about the quality of bone marrow examinations performed in Poland and has a substantial educational value. We believe that after 6 years, EQAhem has significantly improved the quality of bone marrow microscopic examinations performed in Poland.

Although up to 50% of patients with alcoholic liver disease (ALD) resume alcohol consumption after liver transplantation (LT), numerous studies indicate that long-term results are not compromised. This study focused on evaluating the impact of ALD on outcomes up to and beyond the fifth year after LT. Among the 432 primary LT recipients included in this study, 97 underwent transplantation for ALD. Alcohol relapse rate at 10 yr was 33.5%, with younger recipient age being the only independent predictor (p = 0.019). Survival of patients with ALD (77.0%) was similar to those without (79.0%) up to the fifth post-transplant year (p = 0.655) but worse during the five subsequent years among the five-yr survivors (70.6% vs. 92.9%; p = 0.002). ALD was an independent risk factor for poorer survival beyond the fifth post-transplant year (p = 0.049), but not earlier (p = 0.717). Conversely, alcohol relapse increased the risk of death only during the first five post-transplant years (p = 0.039). There were no significant differences regarding graft failure incidence between ALD and non-ALD recipients up to the fifth post-transplant year (7.3% vs. 11.6%; p = 0.255) and beyond (12.9% vs. 5.0%; p = 0.126). In conclusion, pre-transplant diagnosis of ALD yields negative effects on post-transplant outcomes beyond the fifth post-transplant year, not attributable to recidivism. © 2014 John Wiley & Sons A/S.

Preventing problem behavior requires an understanding of earlier factors that are amenable to intervention. The main goals of our prospective longitudinal study were to trace trajectories of child externalizing behavior between ages 3 and 10 years, and to identify patterns of developmentally significant child and parenting risk factors that differentiated pathways of problem behavior. Participants were 218 3-year-old boys and girls who were reassessed following the transition to kindergarten (age 5-6 years) and during the late school-age years (age 10). Mothers contributed ratings of children's externalizing behavior at all three time points. Children's self-regulation abilities and theory of mind were assessed during a laboratory visit, and parenting risk (frequent corporal punishment and low maternal warmth) was assessed using interview-based and questionnaire measures. Four developmental trajectories of externalizing behavior yielded the best balance of parsimony and fit with our longitudinal data and latent class growth analysis. Most young children followed a pathway marked by relatively low levels of symptoms that continued to decrease across the school-age years. Atypical trajectories marked chronically high, increasing, and decreasing levels of externalizing problems across early and middle childhood. Three-year-old children with low levels of effortful control were far more likely to show the chronic pattern of elevated externalizing problems than changing or low patterns. Early parental corporal punishment and maternal warmth, respectively, differentiated preschoolers who showed increasing and decreasing patterns of problem behavior compared to the majority of children. The fact that children's poor effortful regulation skills predicted chronic early onset problems reinforces the need for early childhood screening and intervention services.

The influence of internalizing and externalizing problems on children’s understanding of others’ emotions has mainly been investigated on basic levels of emotion comprehension. So far, studies assessing more sophisticated levels of emotion comprehension reported deficits in the ability to understand others’ emotions in children with severe internalizing or externalizing symptoms. The aim of this study was to investigate the relation between emotion comprehension and interindividual differences, with a focus on internalizing and externalizing behavior in children aged 7–10 years from the general population. A sample of 135 children was tested for emotion understanding using the Test of Emotion Comprehension. Information on internalizing and externalizing behavior was assessed with the Child Behavior Checklist 4/18. Age, bilingual upbringing, and amount of paternal working hours were significant control variables for emotion comprehension. In contrast to prior research, overall level of emotion understanding was not related to externalizing symptoms and correlated positively with elevated levels of somatic complaints and anxious/depressed symptoms. In addition, and in line with previous work, higher levels of social withdrawal were associated with worse performance in understanding emotions elicited by reminders. The present results implicate not only an altered understanding of emotions among more specific internalizing symptoms, but also that these alterations occur already on a low symptom level in a community based sample.

Macrophagic myofasciitis (MMF) is an uncommon inflammatory disorder of muscle believed to be due to persistence of vaccine-derived aluminium hydroxide at the site of injection. The condition is characterised by diffuse myalgias, arthralgia and fatigue. We describe a patient with histologically confirmed MMF whose presentation was atypical with left chest and upper limb pain beginning more than 10 years post vaccination. Treatment with steroids led to symptomatic improvement. Although rare, clinicians should consider MMF in cases of atypical myalgia.

Excessive gestational weight gain may lead to long-term increases in maternal body weight and associated health risks. The purpose of this study was to examine the relationship between maternal body weight and weight-related self-efficacy from early pregnancy to 2 years post-partum. Women with live, singleton term infants from a population-based cohort study were included (n = 595). Healthy eating self-efficacy and weight control self-efficacy were assessed prenatally and at 1 year and 2 years post-partum. Body weight was measured at early pregnancy, before delivery, and 6 weeks, 1 year and 2 years post-partum. Behavioural (smoking, breastfeeding) and sociodemographic (age, education, marital status, income) covariates were assessed by medical record review and baseline questionnaires. Multi-level linear regression models were used to examine the longitudinal associations of self-efficacy measures with body weight. Approximately half of the sample (57%) returned to early pregnancy weight at some point by 2 years post-partum, and 9% became overweight or obese at 2 years post-partum. Body weight over time was inversely related to healthy eating (β = −0.57, P = 0.02) and weight control (β = −0.99, P < 0.001) self-efficacy in the model controlling for both self-efficacy measures as well as time and behavioural and sociodemographic covariates. Weight-related self-efficacy may be an important target for interventions to reduce excessive gestational weight gain and post-partum weight gain. PMID:25244078

In an environment of increasingly liberal attitudes towards marijuana use and legalization, little is known about long-term trajectories of marijuana use among clinical samples of adolescents, and how these trajectories relate to health services utilization over time. Latent growth curve analysis was used to identify distinct trajectories of marijuana use in a clinical sample of adolescents (N=391) over 7 years post substance use treatment in an integrated health system. We examined psychiatric problems and polysubstance use associated with the identified trajectory groups using general linear models. Nonlinear mixed-effects logistic regressions were used to examine associations between health services use and the trajectory groups. We identified three marijuana use trajectory groups: (1) Abstinent (n=117); (2) Low/Stable use (n=174); and (3) Increasing use (n=100). Average externalizing and anxiety/depression scores were significantly lower over time for the Abstinent group compared to the Increasing and Low/Stable groups. The Low Stable and the Increasing group had fewer psychiatric visits over time (p<0.05) and the Low/Stable group used more substance use treatment services over time compared with the Abstinent group (p<0.001). Treated adolescents showed distinct marijuana use patterns, one of which indicated a group of adolescents at risk of increased use over time. These individuals have greater psychiatric and polysubstance use over time, but may not be accessing needed services. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

Distinguishing internal property from external property in kidney transplantation.

PubMed

Prasad, G V Ramesh

2016-08-01

What determines the ownership of human body parts? In this paper, I argue that this question can be informed by an exploration of the cognitive distinction between property external to the human body such as houses, cars or land, and internal property such as organs that are located within anatomical body confines. Each type of property has distinct brain representations and possibly different effects on the sense of self. This distinction may help explain the divergence in post-donation outcomes seen in different kidney donor populations. Poor outcomes in some types of kidney donors may be due not only to a failure in their proper selection by standard medical testing or post-donation care but may also be a manifestation of differing effects on sense of self resulting from transfer of their internal property. Because a kidney is internal property, a hypothesis worth exploring is that those who experience good outcomes post-donation experience dopaminergic activation and a feeling of reward, while those experiencing bad outcomes are instead overcoming cortisol or adrenergic-based stress or fear responses without a corresponding feeling of reward, disrupting of their sense of self. Discussions about the rules for internal property transfer must be based not only on values and laws designed to govern external property but also on cognitive science-based facts, values and judgments that discussions of external property do not presently accommodate. Any future system of rules for governing organ distribution requires a framework different from that of external property to prevent harm to living kidney donors. © 2016 John Wiley & Sons, Ltd.

Post-marketing surveillance (PMS) is an integral part of monitoring adverse events (AEs) following approval of new drugs. Tofacitinib is an oral Janus kinase inhibitor for the treatment of rheumatoid arthritis (RA). An analysis of PMS reports was conducted to evaluate the safety of tofacitinib in a post-marketing setting. Worldwide tofacitinib PMS data received in the Pfizer safety database from November 6, 2012 (first marketing authorization of tofacitinib) to November 5, 2015 were analyzed. Serious AEs (SAEs) of interest were reviewed and reporting rates (RRs) were calculated by dividing the number of SAEs by the estimated 100 patient-years of exposure. Patient exposure was calculated based on estimated worldwide sales and an estimated daily regimen of tofacitinib 5 mg twice daily. During the 3-year reporting period, worldwide post-marketing exposure to tofacitinib since approval was estimated to be 34,223 patient-years. In total, 9291 case reports (82.9% non-serious) were received and 25,417 AEs, 102 fatal cases, and 4352 SAEs were reported. The RRs (per 100 patient-years) for SAEs of interest by Medical Dictionary for Regulatory Activities System Organ Class were 2.57 for infections, 0.91 for gastrointestinal disorders, 0.60 for respiratory disorders, 0.45 for neoplasms, 0.43 for cardiac disorders, and 0.12 for hepatobiliary disorders. Although there are limitations to these data, no new safety risks were revealed in this real-world setting compared with the safety profile identified in the tofacitinib RA clinical development program. Any risks identified through the tofacitinib development program and PMS will continue to be monitored through pharmacovigilance surveillance. Pfizer Inc.

To examine cognitive activity limitations and predictors of outcome 1 year post-trauma in patients admitted to sub-acute rehabilitation after severe traumatic brain injury. The study included 119 patients with severe traumatic brain injury admitted to centralized sub-acute rehabilitation in the Eastern part of Denmark during a 5-year period from 2005 to 2009. Level of consciousness was assessed consecutively during rehabilitation and at 1 year post-trauma. Severity of traumatic brain injury was classified according to duration of post-traumatic amnesia. The cognitive subscale of Functional Independence MeasureTM (Cog-FIM) was used to assess cognitive activity limitations. Multivariate logistic regression analyses were performed to identify predictors of an independent level of functioning. The majority of patients progressed to a post-confusional level of consciousness during the first year post-trauma. At follow-up 33-58% of patients had achieved functional independence within the cognitive domains on the Cog-FIM. Socio-economic status, duration of acute care and post-traumatic amnesia were significant predictors of outcome. Substantial recovery was documented among patients with severe traumatic brain injury during the first year post-trauma. The results of the current study suggest that absence of consciousness at discharge from acute care should not preclude patients from being referred to specialized sub-acute rehabilitation.

This research presents a new testing method in a natural scale for external cladding systems tested on buildings with minimum than 3 floors [1]. The testing method is unique in Romania and it is similar about many fire testing current methods from European Union states. Also, presents the fire propagation and the effect of fire smoke on the building façade composed of thermal insulation. Laboratory of testing and research for building fire safety from National Institute INCERC Bucharest, provides a test method for determining the fire performance characteristics of non-loadbearing external cladding systems and external wall insulation systems when applied to the face of a building and exposed to an external fire under controlled conditions [2]. The fire exposure is representative of an external fire source or a fully-developed (post-flashover) fire in a room, venting through an opening such as a window aperture that exposes the cladding to the effects of external flames, or an external fire source. On the future, fire tests will be experimented for answer demande a number of high-profile fires where the external facade of tall buildings provided a route for vertical fire spread.

Excessive gestational weight gain may lead to long-term increases in maternal body weight and associated health risks. The purpose of this study was to examine the relationship between maternal body weight and weight-related self-efficacy from early pregnancy to 2 years post-partum. Women with live, singleton term infants from a population-based cohort study were included (n = 595). Healthy eating self-efficacy and weight control self-efficacy were assessed prenatally and at 1 year and 2 years post-partum. Body weight was measured at early pregnancy, before delivery, and 6 weeks, 1 year and 2 years post-partum. Behavioural (smoking, breastfeeding) and sociodemographic (age, education, marital status, income) covariates were assessed by medical record review and baseline questionnaires. Multi-level linear regression models were used to examine the longitudinal associations of self-efficacy measures with body weight. Approximately half of the sample (57%) returned to early pregnancy weight at some point by 2 years post-partum, and 9% became overweight or obese at 2 years post-partum. Body weight over time was inversely related to healthy eating (β = -0.57, P = 0.02) and weight control (β = -0.99, P < 0.001) self-efficacy in the model controlling for both self-efficacy measures as well as time and behavioural and sociodemographic covariates. Weight-related self-efficacy may be an important target for interventions to reduce excessive gestational weight gain and post-partum weight gain. © 2014 John Wiley & Sons Ltd.

External apical root resorption (EARR) is a frequent iatrogenic problem following orthodontic treatment in endodontically-treated teeth, about which the literature reports substantial variability in post-orthodontic treatment EARR responses. The main focus of the present study is to clarify whether variants in the interleukin-1 receptor antagonist gene coding for the IL-1ra protein have a positive/negative influence on EARR of endodontically-treated teeth. Ninety-three orthodontic patients were genetically screened for a single nucleotide polymorphism (SNP:rs419598) in the IL1 cluster. The sample was classified into 2 groups: group 1 (affected-group) showed radiographic EARR of more than 2mm; group 2 (control-group), had no EARR or EARR ≤ to 2mm following orthodontic treatment on root-filled teeth. Logistic regression analysis was performed to obtain an adjusted estimate between the SNPs studied and EARR. Genotype distributions, allelic frequencies, adjusted odds ratios (OR) and 95% confidence intervals were also calculated. We found that subjects homozygous [1/1(TT)] for the IL1RN gene [OR:10.85; p=0.001;CI:95%] were at risk of EARR in root-filled teeth. Genetic variants in the antagonist axis balance of the IL1RN (rs419598) have a direct repercussion on the predisposition to post-orthodontic EARR in root-filled teeth. Variants in allele 1 of the interleukin-1 receptor antagonist gene(rs419598) are associated(p=0.001**) with an increased risk of suffering post-orthodontic EARR in root-filled teeth.

AIM To evaluate the efficacy and safety of corneal collagen crosslinking (CXL) to prevent the progression of post-laser in situ keratomileusis (LASIK) corneal ectasia. METHODS In a prospective, nonrandomized, single-centre study, CXL was performed in 20 eyes of 11 patients who had LASIK for myopic astigmatism and subsequently developed keratectasia.The procedure included instillation of 0.1% riboflavin-20% dextrane solution 30 minutes before UVA irradiation and every 5 minutes for an additional 30 minutes during irradiation. The eyes were evaluated preoperatively and at 1-, 3-, 6-, and 12-month intervals. The complete ophthalmologic examination comprised uncorrected visual acuity, best spectacle-corrected visual acuity, endothelial cell count, ultrasound pachymetry, corneal topography, and in vivo confocal microscopy. RESULTS CXL appeared to stabilise or partially reverse the progression of post-LASIK corneal ectasia without apparent complication in our cohort. UCVA and BCVA improvements were statistically significant(P<0.05) beyond 12 months after surgery (improvement of 0.07 and 0.13 logMAR at 1 year, respectively). Mean baseline flattest meridian keratometry and mean steepest meridian keratometry reduction (improvement of 2.00 and 1.50 diopters(D), respectively) were statistically significant (P<0.05) at 12 months postoperatively. At 1 year after CXL, mean endothelial cell count did not deteriorate. Mean thinnest cornea pachymetry increased significantly. CONCLUSION The results of the study showed a long-term stability of post-LASIK corneal ectasia after crosslinking without relevant side effects. It seems to be a safe and promising procedure to stop the progression of post-LASIK keratectasia, thereby avoiding or delaying keratoplasty. PMID:22762048

INTRODUCTION Type 1 endoleak is a rare complication after endovascular abdominal aortic aneurysm repair (EVAR) with a reported frequency up to 2.88%. It is a major risk factor for aneurysmal enlargement and rupture. PRESENTATION OF CASE We present a case of a 68 year old gentleman who was found to have a proximal type 1 endoleak with loss of graft wall apposition on routine surveillance imaging post-EVAR. An initial attempt at endovascular repair was unsuccessful. Given the patient's multiple medical co-morbidities, which precluded the possibility of conventional graft explantation and open repair, we performed a novel surgical technique which did not require aortic cross-clamping. A double-layered Dacron wrap was secured around the infra-renal aorta with Prolene sutures, effectively hoisting the posterior bulge to allow wall to graft apposition and excluding the endoleak. Post-operative CT angiogram showed resolution of the endoleak and a stable sac size. DISCUSSION Several anatomical factors need to be considered when this technique is proposed including aortic neck angulation, position of lumbar arteries and peri-aortic venous anatomy. While an external wrap technique has been investigated sporadically for vascular aneurysms, to our knowledge there is only one similar case in the literature. CONCLUSION Provided certain anatomical features are present, an external aortic wrap is a useful and successful option to manage type 1 endoleak in high-risk patients who are unsuitable for aortic clamping.

In Thailand until 2005 there had been no external quality assessment scheme at the national level for blood coagulation tests. Only a few laboratories had an external quality assessment for these tests. In the year 2005, the Thailand National External Quality Assessment Scheme for Blood Coagulation was founded. To describe the establishment of the Thailand National External Quality Assessment Scheme for Blood Coagulation (including problems encountered and solutions), its progression and expansion, and the improvement of coagulation laboratory practice in Thailand during 2 trial surveys and 4 formal surveys conducted in the first 1 1/2 years. Between 2005 and 2006, the external quality assessment samples for prothrombin time/international normalized ratio and activated partial thromboplastin time were distributed to the participants as well as the instructions and suggestions for the improvement of laboratory practice. From the data collected, the all-method coefficient of variation of the international normalized ratio and activated partial thromboplastin time was calculated for each survey. The number of participants increased during the first 1 1/2 years that the surveys were conducted, from 109 to 127. Survey data demonstrate an improvement in response rate and an increase in the number of laboratories that determine their own reference ranges and repeat this for every change of reagent lot, using the appropriate anticoagulant. The increased precision of tests is indicated by the decrease of the all-method coefficient of variation of the international normalized ratio and activated partial thromboplastin time. Examples of individual laboratory improvement through feedback are also described. The improvement of coagulation laboratory practice both through the instructions provided and liaison with participants was observed during the course of this scheme.

To examine separate mediational models linking (a) menarcheal status or (b) pubertal timing to internalizing and externalizing problems through competence. This study involved cross-sectional analyses of 262 adolescent girls (age: 11-17 years; mean = 14.93, standard deviation = 2.17) enrolled in a longitudinal study examining the association of psychological functioning and smoking with reproductive and bone health. Measures of menarcheal status (pre/post), pubertal timing (early, on-time, or late), internalizing and externalizing behavior, and perceived competence (parent and adolescent report) were obtained. Structural equation modeling was used for analyses. Perceived competence was found to fully mediate the association between menarcheal status and parent report of internalizing and externalizing problems. For adolescent report, there was a full mediation effect for internalizing problems but a partial mediation effect for externalizing problems. Being menarcheal was related to lower competence, which was in turn related to higher internalizing and externalizing problems. Models including pubertal timing were not significant. Perceived competence is important in understanding the associations between menarcheal status and internalizing and externalizing problems. Interventions targeting competence, particularly in postmenarcheal girls, may reduce or prevent problem behaviors. Copyright © 2011 Society for Adolescent Health and Medicine.

Robert 'Skip' Garrett; main propulsion advanced systems technician, and Chris Jacobs; main propulsion systems engineering technician, inspect external tank attachment fittings on the Space Shuttle Discovery as part of it's post-flight processing at NASA's Dryden Flight Research Center. The Space Shuttles receive post-flight servicing in the Mate-Demate Device (MDD) following landings at NASA's Dryden Flight Research Center, Edwards, California. The gantry-like MDD structure is used for servicing the shuttle orbiters in preparation for their ferry flight back to the Kennedy Space Center in Florida, including mounting the shuttle atop NASA's modified Boeing 747 Shuttle Carrier Aircraft. Space Shuttle Discovery landed safely at NASA's Dryden Flight Research Center at Edwards Air Force Base in California at 5:11:22 a.m. PDT, August 9, 2005, following the very successful 14-day STS-114 return to flight mission. During their two weeks in space, Commander Eileen Collins and her six crewmates tested out new safety procedures and delivered supplies and equipment the International Space Station. Discovery spent two weeks in space, where the crew demonstrated new methods to inspect and repair the Shuttle in orbit. The crew also delivered supplies, outfitted and performed maintenance on the International Space Station. A number of these tasks were conducted during three spacewalks. In an unprecedented event, spacewalkers were called upon to remove protruding gap fillers from the heat shield on Discovery's underbelly. In other spacewalk activities, astronauts installed an external platform onto the Station's Quest Airlock and replaced one of the orbital outpost's Control Moment Gyroscopes. Inside the Station, the STS-114 crew conducted joint operations with the Expedition 11 crew. They unloaded fresh supplies from the Shuttle and the Raffaello Multi-Purpose Logistics Module. Before Discovery undocked, the crews filled Raffeallo with unneeded items and returned to Shuttle pa

Study Objective: To evaluate the association between self-reported sleep quality among older adults during inpatient post-acute rehabilitation and one-year survival. Design: Prospective, observational cohort study. Setting: Two inpatient post-acute rehabilitation sites (one community and one Veterans Administration). Participants: Older patients (aged ≥ 65 years, n = 245) admitted for inpatient post-acute rehabilitation. Interventions: None. Measurements and Results: Within one year of post-acute rehabilitation, 57 participants (23%) were deceased. Cox proportional hazards models showed that worse Pittsburgh Sleep Quality Index (PSQI) total scores during the post-acute care stay were associated with increased mortality risk when controlling for amount of rehabilitation therapy received, comorbidities, and cognitive functioning (Hazard ratio [95% CI] = 1.11 [1.02-1.20]). Actigraphically estimated sleep was unrelated to mortality risk. Conclusions: Poorer self-reported sleep quality, but not objectively estimated sleep parameters, during post-acute rehabilitation was associated with shorter survival among older adults. This suggests self-reported poor sleep may be an important and potentially modifiable risk factor for negative outcomes in these vulnerable older adults. Studies of interventions to improve sleep quality during inpatient rehabilitation should therefore be undertaken, and the long-term health benefits of improved sleep should be explored.

Zoster vaccine is a single dose live, attenuated vaccine (ZVL) indicated for individuals ≥50 years-old for the prevention of herpes zoster (HZ). Safety data from clinical trials and post-licensure studies provided reassurance that ZVL is generally safe and well tolerated. The objective of this review was to provide worldwide post-marketing safety information following 10 years of use and >34 million doses distributed. All post-marketing adverse experience (AE) reports received worldwide between 02-May-2006 and 01-May-2016 from healthcare professionals following vaccination with ZVL and submitted to the MSD AE global safety database, were analyzed. A total of 23,556 AE reports, 93% non-serious, were reported. Local injection site reactions (ISRs), with a median time-to-onset of 2 days, were the most frequently reported AEs followed by HZ. The majority of HZ reports were reported within 2 weeks of vaccination and considered, based on time-to-onset, pathogenesis of HZ, and data from clinical trials, to be caused by wild-type varicella-zoster virus (VZV). HZ confirmed by PCR analysis to be VZV Oka/Merck vaccine-strain was identified in an immunocompetent individual 8 months postvaccination and in 4 immunocompromised individuals. Disseminated HZ was reported very rarely (<1%) with 38% occurring in immunocompromised individuals. All reports of disseminated HZ confirmed by PCR as VZV Oka/Merck vaccine-strain were in individuals with immunosuppressive conditions and/or therapy at the time of vaccination. The safety profile of ZVL, following 10 years of post-marketing use, was favorable and consistent with that observed in clinical trials and post-licensure studies. Copyright © 2017 Elsevier Ltd.

Lansford, Jennifer E; Wager, Laura B; Bates, John E; Pettit, Gregory S; Dodge, Kenneth A

2012-04-01

Research suggests that corporal punishment is related to higher levels of child externalizing behavior, but there has been controversy regarding whether infrequent, mild spanking predicts child externalizing or whether more severe and frequent forms of corporal punishment account for the link. Mothers rated the frequency with which they spanked and whether they spanked with a hand or object when their child was 6, 7, and 8 years old. Mothers and teachers rated children's externalizing behaviors at each age. Analyses of covariance revealed higher levels of mother-reported externalizing behavior for children who experienced harsh spanking. Structural equation models for children who experienced no spanking or mild spanking only revealed that spanking was related to concurrent and prior, but not subsequent, externalizing. Mild spanking in one year was a risk factor for harsh spanking in the next year. Findings are discussed in the context of efforts to promote children's rights to protection.

With the growing demand for dental work, trigeminal nerve injuries are increasingly common. This retrospective cohort study examined 53 cases of iatrogenic trigeminal nerve injury seen at the Department of Oral and Maxillofacial Surgery, University Hospitals of Leuven between 2013 and 2014 (0.6% among 8845 new patient visits). Patient records were screened for post-traumatic trigeminal nerve neuropathy caused by nerve injury incurred during implant surgery, endodontic treatment, local anaesthesia, tooth extraction, or specifically third molar removal. The patients ranged in age from 15 to 80years (mean age 42.1years) and 68% were female. The referral delay ranged from 1day to 6.5years (average 10months). The inferior alveolar nerve (IAN) was most frequently injured (28 cases), followed by the lingual nerve (LN) (21 cases). Most nerve injuries were caused during third molar removal (24 cases), followed by implant placement (nine cases) and local anaesthesia injuries (nine cases). Pain symptoms were experienced by 54% of patients suffering IAN injury, compared to 10% of patients with LN injury. Persistent neurosensory disturbances were identified in 60% of patients. While prevention remains the key issue, timely referral seems to be a critical factor for the successful treatment of post-traumatic neuropathy. Copyright © 2018 The Author(s).

To examine the prospective association between symptoms commonly experienced during pregnancy and the mental and general health status of women 14 years post partum. Data used were from the Mater-University of Queensland Study of Pregnancy, a community-based prospective birth cohort study begun in Brisbane, Australia, in 1981. Logistic regression analyses were conducted. Data were available for 5118 women. Women who experienced a higher burden of symptoms during pregnancy were at greater risk of becoming depressed and reporting poorer health status 14 years post partum. Women who experienced major problems during pregnancy were 4 times more likely to be depressed and nearly 8 times more likely to report poorer health status 14 years after the index pregnancy compared with women who experienced few problems. Findings suggest that pregnant women who experience common symptoms during pregnancy are likely to experience poorer mental and self-reported general health 14 years after the pregnancy.

The aim of this study was to assess the feasibility, efficacy and tolerance of external urethral sphincter vaporization in saline for treating detrusor-sphincter dyssynergia. Between 2009 and 2011 a monocentric prospective study of ten men mean age 58±9 years with neurogenic detrusor-sphincter dyssynergia was carried out. Preoperative evaluation included kidney ultrasound scan, 24-hour creatinine clearance, urodynamics, retrograde and voiding urethrocystography and an at least 6 months temporary stent sphincterotomy. Postoperative assessment was composed of an ultrasound scan post-void residual volume measurement when the urethral catheter were removed and 1 year after the procedure, a retrograde and voiding urethrocystography at 3 months and a flexible cystoscopy at 1 year. At the catheter removal, eight patients emptied their bladder at completion, a supra-pubic catheter was temporary left in one case and a patient had a permanent urinary retention. For a mean follow-up of 22±11 months, eight patients emptied their bladder at completion and two had a complete urinary retention related to a detrusor underactivity. An orchitis occurred in one case 1 month after the procedure and an urethral stricture in four cases in 12.75±5.68 months on average. External urethral sphincter vaporisation saline was feasible and efficient for treating detrusor-sphincter dyssynergia but was associated with a high risk of urethral stricture.

Neurosurgery is characterized by a prolonged risk period for surgical site infection (SSI), mainly related to the presence of cerebrospinal fluid (CSF) drains. We aimed to examine factors associated with post-neurosurgical SSIs, focusing on post-operative factors. A prospective cohort study was conducted in a single center over a period of 18 months in Israel. Included were adult patients undergoing clean or clean-contaminated craniotomy, including craniotomies with external CSF drainage or shunts. SSIs were defined by the Centers for Disease Control and Prevention (CDC) criteria for healthcare-associated infections. All patients were followed up for 90 days and those with foreign body insertion for 1 year. We compared patients with and without SSI. A multivariable regression analysis for SSI was conducted including uncorrelated variables significantly associated with SSI. A total of 502 patients were included, with 138 (27.5%) undergoing emergent or urgent craniotomy. The overall SSI rate was 5.6% (28 patients), of which 3.2% (16 patients) were intracerebral. Non-elective surgery, external CSF drainage/monitoring devices, re-operation, and post-operative respiratory failure were independently associated with subsequent SSI. External CSF devices was the only significant risk factor for intracerebral SSIs (p < 0.001). Internal shunts or other foreign body insertions were not associated with SSIs. A phenotypically identical isolate to that causing the SSI was isolated from respiratory secretions prior to the SSI in 4/9 patients with microbiologically documented intracerebral SSIs. Patients with SSIs had longer hospital stay, poorer functional capacity on discharge, and higher 90-day mortality. We raise the possibility of post-operative infection acquisition through external CSF devices. Standard operating procedures for their maintenance are necessary.

Deployment can put soldiers at risk of developing post-traumatic stress symptoms. Despite several longitudinal studies, little is known about the timing of an increase in post-traumatic stress symptoms relative to pre-deployment. Longitudinal studies starting pre-deployment, in which participants are repeatedly measured over time, are warranted to assess the timing of an increase in symptoms to ultimately assess the timing of an increase in treatment demand after deployment. In this large observational cohort study, Dutch military personnel who were deployed to Afghanistan as part of the International Security Assistance Forces between March, 2005, and September, 2008, were assessed for post-traumatic stress symptoms with the Self-Rating Inventory for Post-traumatic Stress Disorder (SRIP) questionnaire. Participants were assessed 1 month before deployment and followed up at 1 month, 6 months, 12 months, 2 years, and 5 years after deployment, with changes in SRIP scores compared with pre-deployment using a mixed model analysis. The primary outcome was the total score of post-traumatic stress symptoms measured with SRIP at pre-deployment and the five follow-up assessments, with a score of 38 used as the cutoff to indicate substantial post-traumatic stress symptoms. Between March, 2005, and September, 2008, 1007 participants were recruited to this study. The results show two important effects of deployment on post-traumatic stress symptoms. A short-term symptom increase within the first 6 months after deployment (symptom increase coefficient for SRIP score vs pre-deployment [β] 0·99, 95% CI 0·50-1·48); and a long-term symptom increase at 5 years after deployment (β 1·67, 1·14-2·20). This study underlines the importance of long-term monitoring of the psychological health of soldiers after deployment because early detection of symptoms is essential to early treatment, which is related to improved psychological health.

To analyze causes of missed diagnosis of hiding post-malleolar fractures in treating ankle joint fractures of pronation-external rotation type according to Lauge-Hansen classification and assess its medium-term outcomes. Among 103 patients with ankle joint fracture of pronation-external rotation type treated from March 2002 to June 2010,9 patients were missed diagnosis,including 6 males and 3 females,with a mean age of 35.2 years old (ranged, 18 to 55 years old) . Four patients were diagnosed during operation, 2 patients were diagnosed 2 or 3 days after first surgery and 3 patients came from other hospital. All the patients were treated remedially with lag screws and lock plates internal fixation. After operation,ankle joint function was evaluated according to American Orthopaedic Foot and Ankle Society (AOFAS). All the 9 patients were followed up, and the duration ranged from 14 to 30 months (averaged, 17 months). No incision infection was found, and all incision healed at the first stage. At the latest follow-up, AOFAS was 83.0 +/- 4.4, the score of 4 patients diagnosed during operation was 85.0 +/- 2.9, and the score of 5 patients treated by secondary operation was 81.0 +/- 5.3. All the patients got fracture union observed by X-ray at a mean time of 2.2 months after operation. There were no complications such as internal fixation loosing, broken and vascular or nerve injuries. Ankle joint fracture of pronation-external rotation type may be combined with hiding post-malleolar fractures. So to patients with ankle joint fracture of pronation-external rotation type, lateral X-ray should be read carefully, and if necessary, CT or MRI examination should be performed. If adding lateral X-ray examination after reduction of exterior and interior ankle joint fixation, the missed diagnosis may be avoided.

This study examined longitudinal effects of cultural stress (a latent factor comprised of bicultural stress, ethnic discrimination, and negative context of reception) on depressive symptoms and a range of externalizing behaviors among recently (≤5 years in the U.S. at baseline) immigrated Hispanic adolescents. A sample of 302 adolescents (53% boys; mean age 14.51 years) completed baseline measures of perceived ethnic discrimination, bicultural stress, and perceived negative context of reception; and outcome measures of depressive symptoms, cigarette smoking, alcohol use, aggressive behavior, and rule-breaking behavior six months post-baseline. A path analysis indicated that higher cultural stress scores predicted higher levels of all outcomes. These effects were consistent across genders, but varied by study site. Specifically, higher cultural stress scores increased depressive symptoms among participants in Miami, but not in Los Angeles. Findings suggest that cultural stress is a clinically relevant predictor of depressive symptoms and externalizing behaviors among Hispanic immigrant adolescents. PMID:25899132

Addition of external carbon sources to post-denitrification systems is frequently used in wastewater treatment plants to enhance nitrate removal. However, little is known about the fate of micropollutants in post-denitrification systems and the influence of external carbon dosing on their removal. In this study, we assessed the effects of two different types and availability of commonly used carbon sources -methanol and ethanol- on the removal of micropollutants in biofilm systems. Two laboratory-scale moving bed biofilm reactors (MBBRs), containing AnoxKaldnes K1 carriers with acclimated biofilm from full-scale systems, were operated in continuous-flow using wastewater dosed with methanol and ethanol, respectively. Batch experiments with 22 spiked pharmaceuticals were performed to assess removal kinetics. Acetyl-sulfadiazine, atenolol, citalopram, propranolol and trimethoprim were easily biotransformed in both MBBRs (biotransformations rate constants k bio between 1.2 and 12.9 L g biomass -1  d -1 ), 13 compounds were moderately biotransformed (rate constants between 0.2 and 2 L g biomass -1  d -1 ) and 4 compounds were recalcitrant. The methanol-dosed MBBR showed higher k bio (e.g., 1.5-2.5-fold) than in the ethanol-dosed MBBR for 9 out of the 22 studied compounds, equal k bio for 10 compounds, while 3 compounds (i.e., targeted sulfonamides) were biotransformed faster in the ethanol-dosed MBBR. While biotransformation of most of the targeted compounds followed first-order kinetics, removal of venlafaxine, carbamazepine, sulfamethoxazole and sulfamethizole could be described with a cometabolic model. Analyses of the microbial composition in the biofilms using 16S rRNA amplicon sequencing revealed that the methanol-dosed MBBR contained higher microbial richness than the one dosed with ethanol, suggesting that improved biotransformation of targeted compounds could be associated with higher microbial richness. During continuous-flow operation, at conditions

Sixty-six feet (62 patients) with displaced intra-articular calcaneal fractures underwent manual reduction and distraction with the use of a triangular tube-to-bar external fixation device and were retrospectively reviewed at a minimum of 1-year post-operative. Final radiographic follow-up revealed complete consolidation in all fractures, maintenance of reduction, and limited degenerative osteoarthrosis about the subtalar joint. Our results indicate that with proper application and attention to detail, restoration of calcaneal morphology using triangular tube-to-bar external fixation should be considered a viable alternative in the treatment of displaced intra-articular fractures of the calcaneus.

Although lung transplantation improves quality of life, most psychosocial research focuses on adverse psychological and social functioning outcomes. Positive effects, particularly in the late-term years as physical morbidities increase, have received little attention. We provide the first data on a psychological benefit - post-traumatic growth (PTG) - and we focused on long-term (>5 yr) survivors. Among 178 patients from a prospective study of mental health during the first two yr post-transplant, we recontacted survivors 6-11 yr post-transplant. We assessed PTG (i.e., positive psychological change resulting from the transplant) and examined its relationship to other patient characteristics with multivariable regression analyses. Sixty-four patients (86% of survivors) were assessed (M = 8.1 yr post-transplant, SD = 1.2). Mean PTG exceeded the scale's midpoint (M = 38.6, SD = 10.0; scale midpoint = 25). Recipients experiencing greater PTG were female (p = 0.022), less educated (p = 0.014), and had a history of post-transplant panic disorder (p = 0.005), greater friend support (p = 0.048), and better perceived health (p = 0.032). Neither other pre- or post-transplant mood and anxiety disorders nor transplant-related morbidities (acute rejection, bronchiolitis obliterans syndrome) predicted PTG. PTG exceeded levels observed in other chronic disease populations, suggesting that lung transplantation may uniquely foster positive psychological change in long-term survivors. PTG occurs despite physical and psychiatric morbidities. Whether PTG promotes other positive post-transplant psychosocial outcomes deserves attention. © 2014 John Wiley & Sons A/S.

The aim of this study was to assess clinical safety and efficacy outcomes of renal denervation executed by an externally delivered, completely noninvasive focused therapeutic ultrasound device. Renal denervation has emerged as a potential treatment approach for resistant hypertension. Sixty-nine subjects received renal denervation with externally delivered focused ultrasound via the Kona Medical Surround Sound System. This approach was investigated across 3 consecutive studies to optimize targeting, tracking, and dosing. In the third study, treatments were performed in a completely noninvasive way using duplex ultrasound image guidance to target the therapy. Short- and long-term safety and efficacy were evaluated through use of clinical assessments, magnetic resonance imaging scans prior to and 3 and 24 weeks after renal denervation, and, in cases in which a targeting catheter was used to facilitate targeting, fluoroscopic angiography with contrast. All patients tolerated renal denervation using externally delivered focused ultrasound. Office blood pressure (BP) decreased by 24.6 ± 27.6/9.0 ± 15.0 mm Hg (from baseline BP of 180.0 ± 18.5/97.7 ± 13.7 mm Hg) in 69 patients after 6 months and 23.8 ± 24.1/10.3 ± 13.1 mm Hg in 64 patients with complete 1-year follow-up. The response rate (BP decrease >10 mm Hg) was 75% after 6 months and 77% after 1 year. The most common adverse event was post-treatment back pain, which was reported in 32 of 69 patients and resolved within 72 h in most cases. No intervention-related adverse events involving motor or sensory deficits were reported. Renal function was not altered, and vascular safety was established by magnetic resonance imaging (all patients), fluoroscopic angiography (n = 48), and optical coherence tomography (n = 5). Using externally delivered focused ultrasound and noninvasive duplex ultrasound, image-guided targeting was associated with substantial BP reduction without any major safety signals. Further

Forms of Spanking and Children’s Externalizing Behaviors

2011-01-01

Research suggests that corporal punishment is related to higher levels of child externalizing behavior, but there has been controversy regarding whether infrequent, mild spanking predicts child externalizing or whether more severe and frequent forms of corporal punishment account for the link. Mothers rated the frequency with which they spanked and whether they spanked with a hand or object when their child was 6, 7, and 8 years old. Mothers and teachers rated children’s externalizing behaviors at each age. Analyses of covariance revealed higher levels of mother-reported externalizing behavior for children who experienced harsh spanking. Structural equation models for children who experienced no spanking or mild spanking only revealed that spanking was related to concurrent and prior, but not subsequent, externalizing. Mild spanking in one year was a risk factor for harsh spanking in the next year. Findings are discussed in the context of efforts to promote children’s rights to protection. PMID:22544988

Post-stroke fatigue may affect the ability to return to work but quantitative studies are lacking. We included 83 first-ever stroke patients <60 years and employed either full-time (n = 77) or part-time (n = 6) at baseline. The patients were recruited from stroke units at Aarhus University Hospital between 2003 and 2005 and were followed for 2 years. Fatigue was assessed by the Multidimensional Fatigue Inventory. Pathological fatigue was defined as a score ≥12 on the General Fatigue dimension. Return to paid work was defined as working at least 10 h per week. Data were analyzed using multivariable logistic regression. A total of 58% of patients had returned to paid work after 2 years. The adjusted Odds Ratio (OR) for returning to paid work was 0.39 (95% confidence interval (CI) 0.16-1.08) for patients with a General Fatigue score ≥12 at baseline. Persisting pathological fatigue after 2 years of follow-up was associated with a lower chance of returning to paid work [adjusted OR 0.29 (95% CI 0.11-0.74)]. Higher scores of General Fatigue at follow-up also correlated negatively with the chance of returning to paid work when analyzing fatigue on a continuous scale (adjusted OR 0.87, 95% CI 0.80-0.94 for each point increase in General Fatigue). Post-stroke fatigue appears to be an independent determinant of not being able to resume paid work following stroke. © 2011 John Wiley & Sons A/S.

To evaluate pain incidence and intensity in patients undergoing septorhinoplasty, and to assess analgesic treatment effectiveness, in the first 7 days after surgery. Prospective outcomes analysis using visual analogue scale assessment of pain intensity in the first 7 post-operative days. Fifty-seven patients were enrolled in the study, 29 women and 28 men, aged 18 to 51 years. All were treated for post-traumatic deformity of the external nose and/or nasal septum, with either septorhinoplasty or septoplasty. In the first 3 days after septorhinoplasty, patients' mean visual analogue scale pain score exceeded the range denoting 'analgesic success', and showed considerable exacerbation in the evening. Patients' pain decreased to a mean score of 15.4 one hour after administration of a nonsteroidal anti-inflammatory drug (metamizole). Analgesia is recommended for all patients in the first 3 days after septorhinoplasty, especially in the early evening.

This study examined longitudinal effects of cultural stress (a latent factor comprised of bicultural stress, ethnic discrimination, and negative context of reception) on depressive symptoms and a range of externalizing behaviors among recently (≤5 years in the U.S. at baseline) immigrated Hispanic adolescents. A sample of 302 adolescents (53% boys; mean age 14.51 years) completed baseline measures of perceived ethnic discrimination, bicultural stress, and perceived negative context of reception; and outcome measures of depressive symptoms, cigarette smoking, alcohol use, aggressive behavior, and rule-breaking behavior six months post-baseline. A path analysis indicated that higher cultural stress scores predicted higher levels of all outcomes. These effects were consistent across genders, but varied by study site. Specifically, higher cultural stress scores increased depressive symptoms among participants in Miami, but not in Los Angeles. Findings suggest that cultural stress is a clinically relevant predictor of depressive symptoms and externalizing behaviors among Hispanic immigrant adolescents.

The purpose of this study was to evaluate the outcomes of elderly patients 75 years of age or older with recurrent non-small cell lung cancer (NSCLC). A total of 1237 consecutive patients with NSCLC underwent pulmonary resection at our institution. Of these patients, 280 experienced postoperative recurrence. The rate of the post-recurrence survival and predictors were analyzed independently in a group of younger patients (<75 years) and a group of elderly patients (≥75 years). There were 215 younger patients (<75 years) and 65 elderly (≥75 years) patients at the time of diagnosis of recurrence. The median post-recurrence survival time and the five-year survival rate of all cases were 25 months and 20.8%, respectively. There were no significant survival differences between the younger and elderly groups (p = 0.20). A univariate analysis determined that gender, Eastern Cooperative Oncology Group performance status, smoking status, histological type and epithelial growth factor receptor (EGFR) mutation status were factors influencing the post-recurrence survival among the elderly patients. In addition, a multivariate analysis determined the EGFR mutation status to be an independent prognostic factor for the post-recurrence survival. Elderly patients 75 years of age or older in this study achieved satisfactory long-term outcomes.

Weight cycling is linked with advanced breast cancer diagnosis, increased risk of cancer reoccurrence and cancer-related mortality. While women treated for breast cancer report challenges with navigating their post-treatment body shape and weight, the effects of weight cycling on body image and mental health have not been elucidated. This study examined associations between weight changes and weight cycling on psychological health (i.e. weight-related guilt, shame and depressive symptoms) among women in the first-year post-treatment. Self-reported assessments of pre-cancer weight cycling, post-treatment weight-related guilt, shame and depressive symptoms, and objective assessments of weight were assessed in a longitudinal sample of 173 women treated for breast cancer (M age  = 55.01 ± 10.96 years). Based on findings from multilevel models, women experienced the most weight-related shame when their weight was heavier than their personal average. Additionally, heavier weight was associated with worse psychological health, particularly for women with a history of stable (vs. cycling) weight pre-cancer. Weight cycling pre-cancer and post-treatment weight change have important implications for psychological well-being. Due to the potential psychological consequences associated with a history of weight cycling, targeted strategies are needed to improve overall health outcomes for women's survivorship after breast cancer.

This study presents data on post-discharge costs of care among patients treated with transcatheter or surgical aortic valve replacement over a two year period. Based on a prospective clinical trial, post-discharge utilization of health services and status of assistance were collected for 151 elderly patients via 2250 monthly telephone interviews, valued using standardized unit costs and analysed using two-part regression models. At month 1 post-discharge, total costs of care are substantially elevated (monthly mean: €3506.7) and then remain relatively stable over the following 23 months (monthly mean: €622.3). As expected, the majority of these costs are related to in-hospital care (~98% in month 1 post-discharge and ~72% in months 2-24). Patients that died during follow-up were associated with substantially higher cost estimates of in-hospital care than those surviving the two-year study period, while patients' age and other patient characteristics were of minor relevance. Estimated costs of outpatient care are lower at month 1 than during the rest of the study period, and not affected by the event of death during follow-up. The estimated costs of nursing care are, in contrast, much higher in year 2 than in year 1 and differ substantially by gender and type of procedure as well as by patients' age. Overall, these monthly cost estimates add up to €10,352 for the first and €7467.6 for the second year post-discharge. Substantial cost increases at month 1 post-discharge and in case of death during follow-up are the main findings of the study, which should be taken into account in future economic evaluations on the topic. Application of standardized unit costs in combination with monthly patient interviews allows for a far more precise estimate of the variability in post-discharge health service utilization in this group of patients than the ones given in previous studies.

To investigate the long-term efficacy of a combination treatment of alendronate, extracorporeal shock and hyperbaric oxygen for osteonecrosis of the femoral head (ONFH) of post-severe acute respiratory syndrome (SARS) patients. The retrospective study was performed including a total of 37 post-SARS ONFH patients (66 hip joints) in the Department of Orthopedics of the General Hospital of Tianjin Medical University between November 2003 and November 2015, consisting of 6 males (11 hip joints) and 31 females (55 hip joints), with age between 19 and 47 years (average 29.9 years). Visual analog scale (VAS) score, Harris score and Association Research Circulation Osseous (ARCO) stage of imaging examination were compared among those before treatment, and at 1, 3, 6, 9 and 12 years after treatment. Paired t -test was used for statistical analysis of VAS and Harris score before and after treatment. Difference of effective rate on all stages was analyzed with Chi-square test. With 12-year follow-up, significant improvements on VAS (6.81 of pre-treatment vs 3.94 of 12-year post-treatment) and Harris score (74.54 of pre-treatment vs 80.14 of 12-year post-treatment) were observed (all p <0.05). Effective rate showed statistical significance among three stages of ARCO ( p <0.05). The combined treatment showed different efficacies on different ARCO stages; the best was on ARCO Phase I. The combined treatment may delay or discontinue the development of ONFH in post-SARS patients.

We examined to what extent internalizing and externalizing problems at age 3 preceded and predicted parental divorce, and if divorce and the time lapse since divorce were related to internalizing and externalizing problems at age 12. Parental ratings of internalizing and externalizing problems were collected with the Child Behavior Checklist (CBCL) in a large sample (N = 6,426) of 3-year-old children. All these children were followed through the age of 12 years, at which parents completed the CBCL again, while teachers completed the Teacher's Report Form. Children whose parents divorced between age 3 and age 12 were compared with children whose families remained intact. Girls whose parents divorced between ages 3 and 12 already showed more externalizing problems at age 3 than girls whose parents stayed married. Higher levels of externalizing problems in girls at age 3 predicted later parental divorce. Parental reports indicated that 12-year-olds with divorced parents showed more internalizing and externalizing problems than children with married parents. Levels of teacher-reported problems were not different between children with married versus divorced parents. However, children whose parents divorced between ages 3 and 12 showed more teacher-rated internalizing problems at age 12 when the divorce was more recent than when the divorce was less recent. Parental ratings of both internalizing and externalizing problems at age 12 were not associated with the time lapse since divorce. Externalizing problems in girls precede and predict later parental divorce. Post-divorce problems in children vary by raters, and may depend on the time lapse since divorce.

Objective Efficacies of the Incredible Years (IY) interventions are well established in children with oppositional defiant disorder (ODD), but not among those with a primary diagnosis of attention-deficit/hyperactivity disorder (ADHD). We sought to evaluate one-year follow-up outcomes among young children with ADHD who were treated with the IY interventions. Method Four- to six-year-olds with ADHD (n=49, 73% males) participated in six months of treatment using the IY parent and child interventions. Results Immediate post-treatment results indicated improvements in parenting, children’s externalizing and attention problems, and social contact at school. At one-year follow up, 22 of 27 variables that showed significant post-treatment effects demonstrated maintenance to one-year follow up. Children with higher ODD symptoms at baseline showed more improvement in oppositionality and total behavior problems, and their mothers showed more improvement on harsh discipline scores. Approximately 70–75% of children were reported by their parents and teachers to fall below clinical cut-offs on measures of externalizing symptoms at the one-year follow up (compared to 50% at baseline) and more than 50% fell below clinical cut-offs on measures of hyperactivity and inattentiveness (all were in the clinical range at baseline). Conclusions Children with ADHD who were treated with the IY parent and child treatment programs showed maintenance of treatment effects one year after treatment. PMID:23020199

To evaluate actual post-pubertal penile size and factors affecting it in hypospadias patients, we retrospectively reviewed medical charts. Hypospadias patients whose external genitalia were categorized into Tanner stage 5, and whose stretched penile length was evaluated at 15 years old or older from April 2008 to April 2015, were enrolled in the present study. Stretched penile length was measured by a single examiner. Actual post-pubertal stretched penile length and factors affecting the post-pubertal stretched penile length were estimated. Statistical analysis was performed using Mann-Whitney U test and univariate and multivariate linear regression models for the determination of independent factors. Thirty patients met the inclusion criteria. Median age at evaluation was 17.2 years. Thirteen and 17 had mild and severe hypospadias, respectively. Endocrinological abnormality was identified in 5. Multivariate analysis showed that the severity of hypospadias and endocrinological abnormality were significant factors affecting stretched penile length. Stretched penile length in 25 patients without endocrinological abnormality was significantly longer than that in those with endocrinological abnormality (p = 0.036). Among patients without endocrinological abnormality, stretched penile length in 13 with severe hypospadias was significantly shorter than that in 12 with mild hypospadias (p = 0.004). While the severity of hypospadias and endocrinological abnormality at post-pubertal evaluation were factors affecting post-pubertal penile size, stretched penile length in patients with severe hypospadias was shorter even in cases without endocrinological abnormality. These results suggest that severe hypospadias is not only a disorder of urethral development, but also a disorder of penile development.

Health-related external cost assessment in Europe: methodological developments from ExternE to the 2013 Clean Air Policy Package.

"Getting the prices right" through internalizing external costs is a guiding principle of environmental policy making, one recent example being the EU Clean Air Policy Package released at the end of 2013. It is supported by impact assessments, including monetary valuation of environmental and health damages. For over 20 years, related methodologies have been developed in Europe in the Externalities of Energy (ExternE) project series and follow-up activities. In this study, we aim at analyzing the main methodological developments over time from the 1990s until today with a focus on classical air pollution-induced human health damage costs. An up-to-date assessment including the latest European recommendations is also applied. Using a case from the energy sector, we identify major influencing parameters: differences in exposure modeling and related data lead to variations in damage costs of up to 21%; concerning risk assessment and monetary valuation, differences in assessing long-term exposure mortality risks together with assumptions on particle toxicity explain most of the observed changes in damage costs. These still debated influencing parameters deserve particular attention when damage costs are used to support environmental policy making.

Abnormal uterine bleeding is the Common presenting complaint in Gynaecology Outpatient Department in all age groups. It is due to the anovulatory cycles which are commonly seen in adolescent and peri-menopausal women. Abnormal uterine bleeding is caused by wide variety of organic or non-organic causes. Histopathological examination of endometrial sample remains the gold standard for diagnosis of endometrial pathology. To study the clinicopathological spectrum of endometrium in abnormal uterine bleeding in peri-menopausal and post-menopausal age groups. The study included prospective analysis of 119 cases of endometrial samples in patients of abnormal uterine bleeding above 40 years of age. The specimens were routinely processed and H&E stained slides were studied. Patients were categorized into peri-menopausal (40-49 years) and post-menopausal (> 50 years) age group. A total of 119 specimens of endometrium were analyzed. Maximum number (73.94%) of cases were from peri-menopausal age group. The most common presenting complaint was menorrhagia (48.86%) followed by post-menopausal bleeding (26.05%). In peri-menopausal age group proliferative endometrium (35.22%) was the predominant histopathological pattern followed by endometrial hyperplasia (23.86%). Atrophic endometrium (25.80%) was the most frequent finding followed by endometrial hyperplasia (19.35%) in post-menopausal age group. Three cases of endometrial carcinoma were reported in post-menopausal age group only. A thorough histopathological work up and clinical correlation is mandatory in cases of abnormal uterine bleeding above the age of 40 years to find out organic lesions. Careful screening can detect early cancer of endometrium which has excellent prognosis and it will help in further management.

Attenuated activity of stress-regulating systems has consistently been reported in boys with conduct problems. Results in studies of girls are inconsistent, which may result from the high prevalence of comorbid post-trauma symptoms. Therefore, the aim of the present study is to investigate post-trauma symptoms as a potential mediator in the relation between stress-regulation systems functioning and conduct problems in female adolescents. The sample consisted of 78 female adolescents (mean age 15.4; SD 1.1) admitted to a closed treatment institution. The diagnosis of disruptive behaviour disorder (DBD) was assessed by a structured interview-the diagnostic interview schedule for children version IV (DISC-IV). To assess post-trauma symptoms and externalizing behaviour problems, self-report questionnaires, youth self report (YSR) and the trauma symptom checklist for Children (TSCC) were used. The cortisol awakenings response (CAR) measured hypothalamic-pituitary-adrenal (HPA) axis activity, whereas autonomous nervous system (ANS) activity was assessed by heart rate (HR), pre-ejection period (PEP) and respiratory sinus arrhythmia (RSA). Independent t-tests were used to compare girls with and without DBD, while path analyses tested for the mediating role of post- trauma symptoms in the relation between stress regulating systems and externalizing behaviour. Females with DBD (n = 37) reported significantly higher rates of post-trauma symptoms and externalizing behaviour problems than girls without DBD (n = 39). Path analysis found no relation between CAR and externalizing behaviour problems. With regard to ANS activity, positive direct effects on externalizing behaviour problems were present for HR (standardized β = 0.306, p = 0.020) and PEP (standardized β = -0.323, p = 0.031), though not for RSA. Furthermore, no relation-whether direct or indirect-could be determined from post-trauma symptoms. Present findings demonstrate that the neurobiological

Nasal pain is a challenging diagnosis and very little has been reported in the neurological literature. The nose is a sophisticated structure regarding its innervation, which is supplied by the first and second divisions of the trigeminal nerve. Painful cranial neuropathies are an important group in the differential diagnosis, although they have been described only scarcely. Here, we report a case that can conform a non-traumatic external nasal nerve neuralgia. A 76-year-old woman was referred to our office due to pain in her left nose. She was suffering from daily excruciating attacks, which were strictly limited to the territory supplied by her left external nasal nerve (left ala nasi and apex nasi). She denied previous traumatisms and the ancillary tests did not yield any underlying pathology. An anesthetic blockade of her left external nasal nerve achieved a marked reduction of the number of episodes as well as their intensity. External nasal neuralgia seems a specific neuralgia causing nasal pain. Anesthetic blockades of the external nasal nerve may be a valid treatment for this condition. © 2015 American Headache Society.

To analyze the prognosis and outcomes of patients who remain free of biochemical failure during the first 5 years after treatment. Between 1991 and 2002, 742 patients with prostate cancer were treated with brachytherapy alone (n = 306), brachytherapy and hormonal therapy (n = 212), or combined implantation and external beam radiotherapy (with or without hormonal therapy; n = 224). These patients were free of biochemical failure (American Society for Therapeutic Radiology and Oncology [ASTRO] definition) during the first 5 post-treatment years and had a documented 5-year prostate-specific antigen (PSA) value. The median follow-up was 6.93 years. The actuarial 10-year freedom from PSA failure rate was 97% using the ASTRO definition and 95% using the Phoenix definition. The median 5-year PSA level was 0.03 ng/mL (range, 0-3.6). The 5-year PSA value was 0.01-0.10 in 31.1%, >0.10-0.2 in 10.2%, >0.2-0.5 in 7.82%, and >0.5 in 3.10%. The 5-year PSA value had prognostic significance, with a PSA value of year freedom from PSA failure rate of 99% with the ASTRO definition and 98% with the Phoenix definition vs. 86% (ASTRO definition) and 81% (Phoenix definition) for a PSA value >or=0.2 ng/mL (n = 81; p < .0001). The treatment regimen had no effect on biochemical failure. None of the 742 patients in this study developed metastatic disease or died of prostate cancer. The results of this study have shown that the prognosis for patients treated with brachytherapy and who remain biochemically free of disease for >or=5 years is excellent and none developed metastatic disease during the first 10 years after treatment. The 5-year PSA value is prognostic, and patients with a PSA value <0.2 ng/mL are unlikely to develop subsequent biochemical relapse.

Dacryocystorhinostomy (DCR) can be performed via an external or endoscopic approach. The use of ultrasonic or piezosurgery has been well described for endoscopic DCRs but is lacking for external DCRs. This study presents a case series of external DCRs performed using piezosurgery evaluating results and complications. Prospective, consecutive case series of patients undergoing primary external DCR for lacrimal drainage insufficiency. A standard external DCR technique was used using 1 of 2 piezosurgery systems for all bone incision. All patients received silicone intubation to the lacrimal system. Surgical outcome was measured in terms of patient-reported epiphora as follows: 1) complete resolution, 2) improvement >50%, 3) improvement <50%, and 4) No improvement. Intra and postoperative complications were also recorded. Fifty-two patients, 14 male and 38 female, were included in the study, with 2 patients having bilateral surgery. The average age of the patients was 55.8 years. The average length of follow up was 221 days. Surgical outcomes showed 72% of patients with complete resolution of epiphora and 21% with >50% improvement. There were 4 patients (7%) who had <50% improvement. There was 1 (2%) intraoperative complication and 2 (4%) postoperative complications recorded. Piezourgery is a viable modality for performing external DCRs. The lack of surgical complications shows a potential for decreased soft tissues damage. The surgical success rate based on patient-reported epiphora is similar to those published for mechanical external DCRs. This modality may benefit the novice surgeon in the reduction of soft and mucosal tissue damage.

Human immunodeficiency virus type 1 (HIV-1) and hepatitis C virus (HCV) viral load determinations are among the most relevant markers for the follow up of patients infected with these viruses. External quality control tools are crucial to ensure the accuracy of results obtained by microbiology laboratories. This article summarized the results obtained from the 2008 SEIMC External Quality Control Program for HIV-1 and HCV viral loads. In the HIV-1 program, a total of five standards were sent. One standard consisted in seronegative human plasma, while the remaining four contained plasma from 3 different viremic patients, in the range of 2-5 log(10) copies/mL; two of these standards were identical aiming to determine repeatability. The specificity was complete for all commercial methods, and no false positive results were reported by the participants. A significant proportion of the laboratories (24% on average) obtained values out of the accepted range (mean +/- 0.2 log(10) copies/mL), depending on the standard and on the method used for quantification. Repeatability was very good, with up to 95% of laboratories reporting results within the limits (D < 0.5 log(10) copias/mL). The HCV program consisted of two standards with different viral load contents. Most of the participants (88,7%) obtained results within the accepted range (mean +/- 1.96 SD log(10) UI/mL). Post-analytical errors due to mistranscription of the results were detected for HCV, but not for the HIV-1 program. Data from this analysis reinforce the utility of proficiency programmes to ensure the quality of the results obtained by a particular laboratory, as well as the importance of the post-analytical phase on the overall quality. Due to the remarkable interlaboratory variability, it is advisable to use the same method and the same laboratory for patient follow up. 2010 Elsevier España S.L. All rights reserved.

Objective To evaluate change in sedentary behavior (SB) and physical activity (PA) over three years following bariatric surgery. Methods A subset of participants in an observational study (n=473 of 2458; 79% female, median body mass index 45kg/m2) wore an activity monitor pre-surgery and at 1–3 annual post-surgery assessments. Results Over the first year, on average, sedentary time decreased from 573 (95%CI 563–582) to 545 (95%CI 534–555) min/d and moderate-to-vigorous intensity PA (MVPA) increased from 77 (95%CI: 71–84) to 106 (95%CI: 98–116) min/wk, or 7 (95%CI: 5–10) to 24 (95%CI: 18–29) min/wk in MVPA bouts ≥10 minutes. There were no changes in these parameters from years 1 to 3 (P for all>.05). The percentage of participants achieving ≥150 min/wk of bout-related MVPA was not different at year 3 [6.5% (95%CI: 3.1–12.7)] vs. pre-surgery [3.4% (95%CI: 1.8–5.0); p=.45]. Most participants followed SB and PA trajectories that paralleled mean change and were consistent with their pre-surgery position in relation to the group. Conclusions On average, bariatric surgical patients make small reductions in SB and increases in PA during the first post-surgery year, which are maintained through 3 years. Still, post-surgery PA levels fall short of PA guidelines for general health or weight control. PMID:26010326

Parenting, attention and externalizing problems: testing mediation longitudinally, repeatedly and reciprocally.

PubMed

Belsky, Jay; Pasco Fearon, R M; Bell, Brian

2007-12-01

Building on prior work, this paper tests, longitudinally and repeatedly, the proposition that attentional control processes mediate the effect of earlier parenting on later externalizing problems. Repeated independent measurements of all three constructs--observed parenting, computer-tested attentional control and adult-reported externalizing problems--were subjected to structural equation modeling using data from the large-scale American study of child care and youth development. Structural equation modeling indicated (a) that greater maternal sensitivity at two different ages (54 months, approximately 6 years) predicted better attentional control on the Continuous Performance Test (CPT) of attention regulation two later ages ( approximately 6/9 years); (2) that better attentional control at three different ages (54 months, approximately 6/9 years) predicted less teacher-reported externalizing problems at three later ages ( approximately 6/8/10 years); and (3) that attentional control partially mediated the effect of parenting on externalizing problems at two different lags (i.e., 54 months--> approximately 6 years--> approximately 8 years; approximately 6 years--> approximately 9 years--> approximately 10 years), though somewhat more strongly for the first. Additionally, (4) some evidence of reciprocal effects of attentional processes on parenting emerged (54 months--> approximately 6 years; approximately 6 years--> approximately 8 years), but not of problem behavior on attention. Because attention control partially mediates the effects of parenting on externalizing problems, intervention efforts could target both parenting and attentional processes.

The internalizing and externalizing problems relating to childhood and adolescent have always been significant. Because there is special considerations in establishing communication with them and hence, the therapeutic methods for these problems must take into account these considerations. As establishing a therapeutic relationship is an important component of effective counseling, it seems that art therapy may help alleviate these problems. The purpose of this study is to determine the effectiveness of art therapy in reducing internalizing and externalizing problems of adolescent girls (14 - 18 years old). This is a semi-experimental study carried out in the form of a pre-test/post-test design with control group. The population of this study includes female students of Gole Laleh School of Art in district 3 of Tehran, Iran, out of which 30 students with internalizing problems and 30 individuals with externalizing problems were selected through targeted sampling. Students were randomly assigned to control and experimental groups. Experimental groups participated in 6 painting sessions designed based on Art therapy theories and previous studies. The material used for diagnosis of the problems in posttest and pretest was an Achenbach self-assessment form. Data were analyzed using a mixed analysis of variance (ANOVA). Our results showed that Art therapy significantly reduced internalizing problems (F = 17.61, P < 0.001); however, its effect in reducing externalizing problems was not significant (F = 3.93, P = 0.06). Art therapy as a practical therapeutic method can be used to improve internalizing problems. To reduce externalizing problems, more sessions may be needed. Thus, future studies are required to insure these findings.

We report 2 years of post-marketing surveillance of the diversion and injection of buprenorphine-naloxone (BNX) film following its introduction in 2011. Interviews were conducted with people who inject drugs regularly (PWID) (2004-2013), opioid substitution therapy clients (2013, n = 492) and key experts (n = 44). Key outcomes were unsanctioned removal of supervised doses, diversion, injection and street price. Prevalence of past 6-month injection among PWID was adjusted for background availability of opioid substitution therapy medications using sales data. Among out-of-treatment PWID, the levels of regular (weekly+) BNX film injection were comparable to methadone and BNX tablets, and lower than mono-buprenorphine, adjusting for background availability. Fewer BNX film clients [3%; 95% (CI) 1-5] regularly injected their medication than mono-buprenorphine clients (25%; 95% CI 11-39), but at levels equivalent to those among methadone (3%; 95% CI 1-6) and BNX tablet clients (2%; 95% CI 0-6). Key experts perceived BNX film needed less supervised dosing time as it dissolved rapidly and was harder to remove from the mouth than sublingual tablets; however, removal of supervised doses was higher among BNX film clients (15%; 95% CI: 10-20) than methadone clients (3%; 95% CI 1-6), and not significantly different from BNX tablet (11%; 95% CI 2-21) and mono-buprenorphine clients (31%; 95% CI 16-46). Two years post-introduction, levels of BNX film diversion and injection remained comparable with those for methadone and BNX tablets, and lower than mono-buprenorphine. We found no evidence that BNX film has lower non-adherence and diversion than the tablet formulation.

The purpose of this study was to analyze the impact of intra-cavitary brachytherapy (ICBT) as boost radiation after external beam radiotherapy (EBRT) in carcinoma of the external auditory canal and middle ear (EACMA): A retrospective analysis. A retrospective study of 18 patients with carcinoma of the EACMA who were treated with a curative intent from the year 1998 to 2010 was carried out. The age of the patients ranged from 25 years to 67 years. There were 11 male patients (61.1%) and 7 female patients (38.9%). A total of 15 (88.2%) patients were treated with curative radiation alone after a biopsy and two patients received post-operative radiation therapy. The patients were initially treated with EBRT with cobalt 60 machine up to 60-64 Gy. In our department, all the patients who were technically suitable for ICBT received an ICBT boost. The overall survival (OS) in these patients ranged from 7 months to 151 months (9 out of 17 patients, no evidence of disease 53%). The OS in patients treated with a combination of EBRT with ICBT was (8 out of 11) 72.7%, P value statistically significant (P value: 0.0024). The multivariate analysis shows statistically significant difference only for patients who got an ICBT boost (P Value: 0.020). ICBT as a boost after EBRT has got a positive impact on the OS. In conclusion, our results demonstrate that radical radiation therapy (EBRT and ICBT) is the treatment of choice for stage T2, carcinoma of EACMA.

We evaluated the effect of the antioxidant N-acetyl-L-cysteine (NAC) on the levels of reactive oxygen species (ROS), DNA double strand breaks (DSB) and micronuclei (MN) induced by internal and external irradiation using a rat thyroid cell line PCCL3. In internal irradiation experiments, ROS and DSB levels increased immediately after 131 I addition and then gradually declined, resulting in very high levels of MN at 24 and 48 h. NAC administration both pre- and also post- 131 I addition suppressed ROS, DSB and MN. In external irradiation experiments with a low dose (0.5 Gy), ROS and DSB increased shortly and could be prevented by NAC administration pre-, but not post-irradiation. In contrast, external irradiation with a high dose (5 Gy) increased ROS and DSB in a bimodal way: ROS and DSB levels increased immediately after irradiation, quickly returned to the basal levels and gradually rose again after >24 h. The second phase was in parallel with an increase in 4-hydroxy-2-nonenal. The number of MN induced by the second wave of ROS/DSB elevations was much higher than that by the first peak. In this situation, NAC administered pre- and post-irradiation comparably suppressed MN induced by a delayed ROS elevation. In conclusion, a prolonged ROS increase during internal irradiation and a delayed ROS increase after external irradiation with a high dose caused serious DNA damage, which were efficiently prevented by NAC. Thus, NAC administration even both after internal or external irradiation prevents ROS increase and eventual DNA damage.

Infancy parenting and externalizing psychopathology from childhood through adulthood: developmental trends.

PubMed

Lorber, Michael F; Egeland, Byron

2009-07-01

Developmental models and previous findings suggest that early parenting is more strongly associated with externalizing problems in early childhood than it is in adolescence. In this article, the authors address whether the association of poor-quality infancy parenting and externalizing problems "rebounds" in adulthood. Poor-quality infancy parenting was associated with externalizing problems at kindergarten and first grade (mother report) as well as at 23 and 26 years (self report). Infancy parenting was not significantly associated with either mothers' or youths' reports of externalizing problems at 16 years. These findings are consistent with the notion that poor-quality infancy parenting is a risk factor for externalizing problems in developmental periods for which externalizing behavior is most deviant.

This study examined the prevalence of childbirth-related post-traumatic stress (PTS) symptoms at 2 years postpartum and the relationship between such symptoms and both self-reported parenting stress and perceptions of the mother-child relationship. 81 women completed measures of childbirth-related PTS symptoms at 6 weeks and 3 months postpartum; these results were used in an exploration of their predictive links with mother-child relationship and parenting measures at 2 years. 17.3% of respondents reported some PTS symptoms at a clinically significant level at 2 years postpartum. However, these symptoms were only weakly linked to parenting stress and were not related to mothers' perceptions of their children. However earlier PTS symptoms within 3 months of childbirth did show limited associations with parenting stress at 2 years but no association with child relationship outcomes once current depression was taken into account. Implications for clinical practice and the concept of childbirth-related post-traumatic stress disorder are discussed.

Resection of cervical vagal schwannoma via a post-auricular approach.

PubMed

Roh, Jong-Lyel

Cervical vagal schwannomas are extremely rare and gross total resection is the standard treatment modality. However, because the conventional cervical approach leaves an incision scar in a visible area, other approaches need to be developed for young women who want the postoperative scar to be invisible. A 28-year-old female underwent complete resection of a 4x4 cm tumor in her right upper neck via a post-auricular approach using an inverted V-shaped incision along the post-auricular sulcus and hairline. The tumor was a schwannoma originating from the right cervical vagus nerve. Postoperatively, right vocal cord paralysis developed despite careful dissection but completely recovered within 6 months after surgery. The patient was satisfied with an invisible external scar which was hidden by her auricle and hair. A cervical vagal schwannoma can be successfully removed by making an incision in a potentially invisible area.

Determination of the size of testes and epididymes on the right and left side, in healthy boys in various age groups with use of non-invasive ultrasound examination method and the method of external linear measurements. 2. Determination of age, when intensive growth of testicular and epididymal size starts. 3. Determination whether there are statistically significant differences between the size of the right and the left testis, as well as between the right and left epididymis. 4. Evaluation of the ultrasound method and method of external linear measurements in their use for scientific investigations. 309 boys, aged from 1 day to 17 years of life, treated in the Clinical Department of Paediatric Surgery and Traumatology of the Medical University in Lublin from 2009 to 2010 due to diseases needed to be treated surgically, but not the scrotum, were examined in this study. No pathologies influencing the development of genital organs were found in these boys. Dimension of the testes was studied with ultrasound method and with method of external linear measurements. Dimension of epididymes was only examined with ultrasound method. In every age group the author calculated mean arithmetical values for: testiscular length, thickness, width and volume, as well as epididymal depth and basis. With consideration of standard deviation (X+/-1 SD) it was possible to define the range of dimension of healthy testes and epididymes and their change with age. Final dimensions of the right and left testis as well as of the right and left epididymis were compared. Dimensions of the testis on the same side of body acquired with the ultrasound method and acquired with the method of external linear measurements were compared. Statistical work-up with Wilcoxon test for two dependent groups was implemented. Ultrasound evaluation pointed to intensive 2.5-times increase in testicular length and width, and 2-times increase in testicular thickness in boys aged 10 to 17 years. Mean volume of

Race and sex disparities in in-hospital treatment and outcomes of patients with acute myocardial infarction (MI) have been described, but little is known about race and sex differences in post-MI angina and long-term risk of unplanned rehospitalization. We examined race and sex differences in post-MI angina frequency and 1-year unplanned rehospitalization to identify factors associated with unplanned rehospitalization, testing for whether race and sex modify these relationships. Using TRANSLATE-ACS (Treatment With Adenosine Diphosphate Receptor Inhibitors: Longitudinal Assessment of Treatment Patterns and Events after Acute Coronary Syndrome) data, we examined 6-week and 1-year angina frequency and 1-year unplanned rehospitalization stratified by race and sex among MI patients treated with percutaneous coronary intervention. We used multivariable logistic regression to assess factors associated with unplanned rehospitalization and tested for interactions among angina frequency, race, and sex. A total of 11 595 MI patients survived to 1 year postdischarge; there were 66.6% white male patients, 24.3% white female patients, 5.3% black male patients, and 3.8% black female patients. Overall, 29.7% had angina at 6 weeks, and 20.6% had angina at 1 year postdischarge. Relative to white patients, black patients were more likely to have angina at 6 weeks (female: 44.2% versus 31.8%; male: 33.5% versus 27.1%; both P<0.0001) and 1 year (female: 49.4% versus 38.9%; male: 46.3% versus 31.1%; both P<0.0001). Rates of 1-year unplanned rehospitalization were highest among black female patients (44.1%), followed by white female patients (38.4%), black male patients (36.4%), and white male patients (30.2%, P<0.0001). In the multivariable model, 6-week angina was most strongly associated with unplanned rehospitalization (hazard ratio, 1.49; 95% confidence interval, 1.36-1.62; P<0.0001); this relationship was not modified by race or sex (adjusted 3-way P interaction =0.41).

Marine sediment remediation at the United Heckathorn Superfund Site in Richmond, California, was completed in April 1997. The Record of Decision included a requirement for five years of post-remediation monitoring be conducted in the waterways near the site. The present monitoring year, 2001? 2002, is the fifth and possibly final year of post-remediation monitoring. In March 2002, water and mussel tissues were collected from the four stations in and near Lauritzen Channel that have been routinely monitored since 1997-98. A fifth station in Parr Canal was sampled in Year 5 to document post-remediation water and tissue concentrations there. Dieldrin andmore » dichlorodiphenyl trichloroethane (DDT) were analyzed in water samples and in tissue samples from resident (i.e., naturally occurring) mussels. As in Years 3 and 4, mussels were not transplanted to the study area in Year 5. Year 5 concentrations of dieldrin and total DDT in water and total DDT in tissue were compared with those from Years 1 through 4 of post-remediation monitoring, and with preremediation data from the California State Mussel Watch Program and the Ecological Risk Assessment for the United Heckathorn Superfund Site. Year 5 water samples and mussel tissues were also analyzed for polychlorinated biphenyls (PCB), which were detected in sediment samples during Year 2 monitoring and were added to the water and mussel tissue analyses in 1999. Contaminants of concern in Year 5 water samples were analyzed in both bulk (total) phase and dissolved phase, as were total suspended solids, to evaluate the contribution of particulates to the total contaminant concentration.« less

Nodular fasciitis is a pseudosarcomatous reactive process composed of fibroblasts and myofibroblasts, and it is most common in the upper extremities. Nodular fasciitis of the external auditory canal is rare. To the best of our knowledge, less than 20 cases have been reported to date. We present a case of nodular fasciitis arising in the cartilaginous part of the external auditory canal. A 19-year-old man complained of an auricular mass with pruritus. Computed tomography showed a 1.7 cm sized soft tissue mass in the right external auditory canal, and total excision was performed. Histologic examination revealed spindle or stellate cells proliferation in a fascicular and storiform pattern. Lymphoid cells and erythrocytes were intermixed with tumor cells. The stroma was myxoid to hyalinized with a few microcysts. The tumor cells were immunoreactive for smooth muscle actin, but not for desmin, caldesmon, CD34, S-100, anaplastic lymphoma kinase, and cytokeratin. The patient has been doing well during the 1 year follow-up period. PMID:27304679

A high-resolution assessment of health impacts from air pollution and related external cost has been conducted for Denmark using the integrated EVA model system. The EVA system is based on the impact-pathway methodology, where the site-specific emissions will result, via atmospheric transport and chemistry, in a concentration distribution, which together with detailed population data, is used to estimate the population-level exposure. Using exposure-response functions and economic valuations, the exposure is transformed into impacts on human health and related external costs. In this study we have used a coupling of two chemistry transport models to calculate the air pollution concentration at different domain and scales; the Danish Eulerian Hemispheric Model (DEHM) to calculate the air pollution levels in the Northern Hemisphere with a resolution down to 5.6 km x 5.6 km and the Urban Background Model (UBM) to further calculate the air pollution in Denmark at 1 km x 1 km resolution using results from DEHM as boundary conditions. Both the emission data as well as the population density has been represented in the model system with the same high resolution. Previous health impact assessments related to air pollution have been made on a lower resolution. In this study, the integrated model system, EVA, has been used to estimate the health impacts and related external cost for Denmark at a 1 km x 1 km resolution. New developments of the integrated model system will be presented as well as the development of health impacts and related external costs in Europe and Denmark over a period of 36 years (1979-2014).

Post-transcriptional modifications in development and stem cells.

Cells adapt to their environment by linking external stimuli to an intricate network of transcriptional, post-transcriptional and translational processes. Among these, mechanisms that couple environmental cues to the regulation of protein translation are not well understood. Chemical modifications of RNA allow rapid cellular responses to external stimuli by modulating a wide range of fundamental biochemical properties and processes, including the stability, splicing and translation of messenger RNA. In this Review, we focus on the occurrence of N 6 -methyladenosine (m 6 A), 5-methylcytosine (m 5 C) and pseudouridine (Ψ) in RNA, and describe how these RNA modifications are implicated in regulating pluripotency, stem cell self-renewal and fate specification. Both post-transcriptional modifications and the enzymes that catalyse them modulate stem cell differentiation pathways and are essential for normal development. © 2016.

Background: It is well documented that friends’ externalizing problems and negative parent–child interactions predict externalizing problems in adolescence, but relatively little is known about the role of siblings. This four-wave, multi-informant study investigated linkages of siblings’ externalizing problems and sibling–adolescent negative interactions on adolescents’ externalizing problems, while examining and controlling for similar linkages with friends and parents. Methods: Questionnaire data on externalizing problems and negative interactions were annually collected from 497 Dutch adolescents (M = 13.03 years, SD = 0.52, at baseline), as well as their siblings, mothers, fathers, and friends. Results: Cross-lagged panel analyses revealed modest unique longitudinal paths from sibling externalizing problems to adolescent externalizing problems, for male and female adolescents, and for same-sex and mixed-sex sibling dyads, but only from older to younger siblings. Moreover, these paths were above and beyond significant paths from mother–adolescent negative interaction and friend externalizing problems to adolescent externalizing problems, 1 year later. No cross-lagged paths existed between sibling–adolescent negative interaction and adolescent externalizing problems. Conclusions: Taken together, it appears that especially older sibling externalizing problems may be a unique social risk factor for adolescent externalizing problems, equal in strength to significant parents’ and friends’ risk factors.

Driving under the influence of alcohol is a leading cause of injury and premature death among young adults, and college-educated individuals are at particularly high risk. Less is known about driving under the influence of other drugs, which is on the rise. This study describes prospective seven-year trends in alcohol and other drug (AOD)-involved driving among a young-adult sample beginning with their second year of college (i.e., Years 2-8), and documents the extent of continuity in such behaviors across time. Originally recruited as incoming first-year students at one large public university, participants (n=1194) were interviewed annually about how frequently they drove while drunk/intoxicated (DWI), after drinking any alcohol (DAD), and/or while under the influence of other drugs (DD). Follow-up rates were high (>75% annually). Among participants with access to drive a car, annual prevalence peaked in Year 4 (modal age 21) for both DWI (24.3% wt ) and DD (19.1% wt ) and declined significantly thereafter through Year 8 (both ps<0.05). DAD was far more prevalent than DWI or DD, increasing from 40.5% wt in Year 2 to 66.9% wt in Year 5, and plateauing thereafter. Among marijuana-using participants, likelihood of DD was consistently greater than the likelihood of DWI among Heavy Episodic and Light-to-Moderate drinkers, and it declined significantly during Years 5-8 (p<0.05). Post-college declines in heavy drinking and DWI prevalence were encouraging but did not necessarily translate to reductions in likelihood of engaging in DWI, depending on drinking pattern. College-educated individuals represent an important target for AOD-involved driving prevention. Copyright © 2017 Elsevier B.V. All rights reserved.

Post-transplant increased levels of serum sCD30 is a marker for prediction of kidney allograft loss in a 5-year prospective study.

PubMed

Delgado, Julio C; Pavlov, Igor Y; Shihab, Fuad S

2009-12-01

Levels of sCD30 represent a biomarker for early outcome in kidney transplantation. The purpose of this study was to determine the role of sCD30 levels for prediction of graft loss in the late post-transplant period. Sera were collected immediately pre-transplant and yearly thereafter for up to 5-year post-transplant in 37 primary renal transplant recipients. Levels of serum sCD30 were tested using a fluorescent microsphere assay. Levels of sCD30 significantly decreased after transplantation and remained normal in 34 patients without graft loss up to 5-year post-transplant. Elevated levels of serum sCD30 preceded the increase of serum creatinine in patients with subsequent graft loss. Elevated levels of serum sCD30 post-transplant might be a marker for predicting subsequent graft loss in the post-transplant period.

With expanded access to automatic external defibrillators, hundreds of lives could be saved on a daily basis. By training nonphysician providers, such as emergency medical service personnel or first responders, this life-saving medical equipment could help improve the survival rates for people suffering from cardiac arrest. During the last two years, state lawmakers have begun to enact legislation that develops training standards and provides immunity from civil liability for automatic external defibrillator users.

This study investigated whether children scoring higher on a polygenic plasticity index based on five dopaminergic genes (DRD4, DRD2, DAT1, MAOA, and COMT) benefited the most from the Incredible Years (IY) parent program. Data were used from a randomized controlled trial including 341 Dutch families with 4- to 8-year-old children (55.7% boys) showing moderate to high levels of problem behavior. IY proved to be most effective in decreasing parent-reported (but not observed) externalizing behavior in boys (but not girls) carrying more rather than fewer dopaminergic plasticity alleles; this Gene × Intervention effect was most pronounced in the case of boys whose parents' manifested the most positive change in parenting in response to the intervention. These results proved robust across a variety of sampling specifications (e.g., intention to treat, ethnicity). © 2016 The Authors.

Asymptotic co- and post-seismic displacements in a homogeneous Maxwell sphere

NASA Astrophysics Data System (ADS)

Tang, He; Sun, Wenke

2018-07-01

The deformations of the Earth caused by internal and external forces are usually expressed through Green's functions or the superposition of normal modes, that is, via numerical methods, which are applicable for computing both co- and post-seismic deformations. It is difficult to express these deformations in an analytical form, even for a uniform viscoelastic sphere. In this study, we present a set of asymptotic solutions for computing co- and post-seismic displacements; these solutions can be further applied to solving co- and post-seismic geoid, gravity and strain changes. Expressions are derived for a uniform Maxwell Earth by combining the reciprocity theorem, which links earthquake, tidal, shear and loading deformations, with the asymptotic solutions of these three external forces (tidal, shear and loading) and analytical inverse Laplace transformation formulae. Since the asymptotic solutions are given in a purely analytical form without series summations or extra convergence skills, they can be practically applied in an efficient way, especially when computing post-seismic deformations and glacial isotactic adjustments of the Earth over long timescales.

Le cholestéatome du méat acoustique externe se définit comme une accumulation de kératine en regard d’une érosion osseuse de nature ostéitique. C’est une entité otologique rare ou peut diagnostiquée. Le but de notre travail est d’illustrer sur la base d’un cas un cholestéatome du méat acoustique externe. Il s’agit d’un patient âgé de 65 ans diabétique et hypertendu sous traitement, présentant depuis 3 mois une otalgie droite intense, insomniante, avec hypoacousie, otorrhée purulente minime et paralysie faciale droite grade V. Le diagnostic évoqué était dans un premier temps celui d’otite externe maligne. Il a été mis sous traitement antibiotique sans amélioration. L’examen otologique a trouvé une lésion ulcéro-bourgeonnante de la paroi postérieure du méat acoustique externe droit, une biopsie systématique de la lésion a été pratiquée et a conclu à un cholestéatome. Le patient a bénéficié d’une tympanoplastie en technique ouverte. Le cholestéatome du méat acoustique externe est rare, la symptomatologie clinique n’est pas spécifique, le scanner des rocher est d’un grand apport pour le diagnostic positif montrant un cratère osseux du méat acoustique externe. Le traitement dépend de l’extension des lésions allant des simples soins locaux à une tympanoplastie en technique ouverte. Le cholestéatome du méat acoustique externe peut revêtir plusieurs aspects, et prêter confusion avec d’autres pathologies du méat acoustique externe. PMID:28154624

Background and purpose Stroke affects mortality, functional ability, quality of life and incurs costs. The primary objective of this study was to estimate the costs of stroke care in Sweden by level of disability and stroke type (ischemic (IS) or hemorrhagic stroke (ICH)). Method Resource use during first and second year following a stroke was estimated based on a research database containing linked data from several registries. Costs were estimated for the acute and post-acute management of stroke, including direct (health care consumption and municipal services) and indirect (productivity losses) costs. Resources and costs were estimated per stroke type and functional disability categorised by Modified Rankin Scale (mRS). Results The results indicated that the average costs per patient following a stroke were 350,000SEK/€37,000–480,000SEK/€50,000, dependent on stroke type and whether it was the first or second year post stroke. Large variations were identified between different subgroups of functional disability and stroke type, ranging from annual costs of 100,000SEK/€10,000–1,100,000SEK/€120,000 per patient, with higher costs for patients with ICH compared to IS and increasing costs with more severe functional disability. Conclusion Functional outcome is a major determinant on costs of stroke care. The stroke type associated with worse outcome (ICH) was also consistently associated to higher costs. Measures to improve function are not only important to individual patients and their family but may also decrease the societal burden of stroke. PMID:28384164

The aim of this study is to determine the prevalence rates of depressive, anxiety and PTSDs, and the risk factors for psychological symptoms at 6 years after occupational injury. This longitudinal study followed workers who were occupationally injured in 2009. Psychological symptoms and return to work were assessed at 3 and 12 months after injury. Injured workers who had completed the initial questionnaire survey at 3 or 12 months after injury were recruited. A self-administered questionnaire was mailed to the participants. For workers with high Brief Symptom Rating Scale and Post-traumatic Symptom Checklist scores, an in-depth psychiatric evaluation was performed using the Mini-international Neuropsychiatric Interview. A total of 570 workers completed the questionnaire (response rate, 28.7%). Among them, 243 (42.6%) had high psychological symptom scores and were invited for a phone interview; 135 (55.6%) completed the interview. The estimated rates of major depression and post-traumatic stress disorder (PTSD)/partial PTSD were 9.2 and 7.2%, respectively, and both these rates were higher at 6 years after injury than at 12 months after injury (2.0 and 5.1%). After adjustment for family and social factors, the risk factors for high psychological scores were length of hospitalization immediately after injury, affected physical appearance, repeated occupational injuries, unemployment, and number of quit jobs after the injury. At 6 years after occupational injury, the re-emergence of psychiatric disorders was observed. Relevant factors for poor psychological health were severity of injury and instability of work. Periodic monitoring of psychological and physical health and economic stability are warranted.

Stance and strategy: post-structural perspective and post-colonial engagement to develop nursing knowledge.

PubMed

Sochan, Anne M

2011-07-01

How should nursing knowledge advance? This exploration contextualizes its evolution past and present. In addressing how it evolved in the past, a probable historical evolution of its development draws on the perspectives of Frank & Gills's World System Theory, Kuhn's treatise on Scientific Revolutions, and Foucault's notions of Discontinuities in scientific knowledge development. By describing plausible scenarios of how nursing knowledge evolved, I create a case for why nursing knowledge developers should adopt a post-structural stance in prioritizing their research agenda(s). Further, by adopting a post-structural stance, I create a case on how nurses can advance their disciplinary knowledge using an engaging post-colonial strategy. Given an interrupted history caused by influence(s) constraining nursing's knowledge development by power structures external, and internal, to nursing, knowledge development can evolve in the future by drawing on post-structural interpretation, and post-colonial strategy. The post-structural writings of Deleuze & Guattari's understanding of 'Nomadology' as a subtle means to resist being constrained by existing knowledge development structures, might be a useful stance to understanding the urgency of why nursing knowledge should advance addressing the structural influences on its development. Furthermore, Bhabha's post-colonial elucidation of 'Hybridity' as an equally discreet means to change the culture of those constraining structures is an appropriate strategy to enact how nursing knowledge developers can engage with existing power structures, and simultaneously influence that engagement. Taken together, 'post-structural stance' and 'post-colonial strategy' can refocus nursing scholarship to learn from its past, in order to develop relevant disciplinary knowledge in its future. © 2011 Blackwell Publishing Ltd.

Electrical stimulation in biology and gene expression has attracted considerable attention in recent years. However, it is inconvenient that the electric stimulation needs to be supplied an implanted power-transported wire connecting the external power supply. Here, we fabricated a self-powered composite nanofiber (CNF) and developed an electric generating system to realize electrical stimulation based on the electromagnetic induction effect under an external rotating magnetic field. The self-powered CNFs generating an electric signal consist of modified MWNTs (m-MWNTs) coated Fe 3 O 4 /PCL fibers. Moreover, the output current of the nanocomposites can be increased due to the presence of the magnetic nanoparticles during an external magnetic field is applied. In this paper, these CNFs were employed to replace a bullfrog's sciatic nerve and to realize the effective functional electrical stimulation. The cytotoxicity assays and animal tests of the nanocomposites were also used to evaluate the biocompatibility and tissue integration. These results demonstrated that this self-powered CNF not only plays a role as power source but also can act as an external power supply under an external rotating magnetic field for noninvasive the replacement of injured nerve.

In the first 24h after pacemaker or implantable cardioverter/defibrillator (ICD) implantation or replacement, the occurrence of hematoma and pain in the surgically treated region is not infrequent and may result in re-intervention and/or more severe complications, such as infections. Currently, the post-implant phase management is very empiric. The aim of this study was to test the clinical applicability and usefulness of an external close-circuit cooling system for the management of the early post-implant period in patients with high risk of hematoma due to anticoagulant and/or antiplatelet therapy. We studied 135 patients (78M; 71±11years) with high risk of hematoma occurrence after pace-maker (63 patients) or ICD (72 patients) implantation or replacement. Immediately after the intervention, a closed-circuit cooling system (CAREPACE™ system, Zamar, Italy) was externally applied on the pre-pectoral region to each patient and maintained for 24h. The system has a compressive pad and a refrigerating circuit in which non-toxic glycolic fluid is pumped. The fluid temperature was set and kept at 5°C for the whole period. The compressive and cooling effect of the system was well tolerated by all the patients at the temperature set. Four patients complained of noise due to machine operation, but in none the treatment was interrupted. The average length of hospital stay was 2.8±0.4days. No clinically significant hematoma was observed at discharge and after one month follow-up visit. This new system can be used for the management of the early phase after device implantation or replacement and appears clinically useful and well tolerated. Further studies on a larger scale are needed to test the potential reduction of post-intervention complications and the cost-effectiveness of this device. Copyright © 2017 Elsevier B.V.

To achieve the desired outcome in rhinoplasty depends on many factors. Osteotomy and surgical reshaping of nasal bones are important steps that require careful planning and execution. The availability of different tools raises the question of which one provides significant advantages for both technique and surgical outcome. Our prospective randomized pilot study compared the outcome of post-traumatic rhinoplasty performed with two different external techniques: ultrasound osteotomic cut using the Piezosurgery Medical Device (Mectron, Carasco, Italy) and traditional external osteotomy. Forty-four lateral osteotomies of the nasal wall were performed in twenty-two patients. In twelve patients the osteotomies were conducted with a 2-mm traditional osteotome (control group), while in the remaining ten patients these were done with the Piezosurgery Medical Device (experimental group). At the postoperative evaluation, significantly lower pain, edema and ecchymosis were noticed in the experimental group (p<0.05). Moreover, the endoscopic evaluation showed fewer mucosal injuries in the experimental group (p<0.05), whereas bleeding, symmetry of the pyramid and presence of external scars, were similar in the two groups. In the present study, Piezosurgery Medical Device allowed for safe lateral osteotomies in rhinoplasty preliminarily demonstrating the potential to reduce some of the most frequent complications of rhinoplasty.

Several humeral lengthening or simultaneous deformity corrections through one osteotomy using various external fixators were reported, while literature regarding correction of shortening and proximal varus deformity is scarce. This retrospective clinical study evaluated the results of preforming an acute correction and delayed lengthening in young adults through two osteotomies using monorail external fixator. We report seven patients with various pathologies who underwent humeral proximal deformity correction and lengthening between 2009 and 2015. Pre-operative and post-operative clinical and radiographic data were collected. The mean follow-up time was 33.4 months (25-46 months). The humeral neck-shaft angle improved from 97.9° (85-110°) to 138.6° (135-145°). The magnitude of lengthening achieved was average 7.6 cm (range, 6-10 cm) at an average healing index of lengthening of 30.2 days/cm (range, 27.7-35.4 days/cm). There was a significant increase in range of shoulder abduction, and active abduction improved from pre-operative 136.4° (range, 95-160°) to post-operative 166.4° (range, 150-180°). The DASH score improved significance from 23.29 ± 8.36 to 6.57 ± 3.65 (t = 4.848; p < 0.001). Acute deformity correction and gradual lengthening with the monorail external fixator can be used for humeral shortening and proximal varus angular deformity. Functional improvement is expected after surgery and post-operative therapy.

How to Measure Qualitative Understanding of DC-Circuit Phenomena - Taking a Closer Look at the External Representations of 9-Year-Olds

NASA Astrophysics Data System (ADS)

Kallunki, Veera

2013-04-01

Pupils' qualitative understanding of DC-circuit phenomena is reported to be weak. In numerous research reports lists of problems in understanding the functioning of simple DC-circuits have been presented. So-called mental model surveys have uncovered difficulties in different age groups, and in different phases of instruction. In this study, the concept of qualitative understanding, and the content or position of reported mental models of DC-circuit phenomena are discussed. On the grounds of this review, new tools for investigating qualitative understanding and analysing external representations of DC-circuit phenomena are presented. According to this approach, the external representations of DC-circuit phenomena that describe pupils' expressed conceptions of the topic should include both empirical-based models and theoretical explanations. In the empirical part of this study , third-graders (9-year-olds) learning DC-circuit phenomena in a comprehensive school in a small group were scrutinised. The focus of the study is the external representations manifested in the talk of the small group. The study challenges earlier studies, which claim that children exhibit a wide range of qualitative difficulties when learning DC-circuit phenomena. In this study it will be shown that even in the case of abstract subject matter like DC-circuit phenomena, small groups that highlight empirical-based modelling and activate talk can be a fruitful learning environment, where pupils' qualitative understanding really develops. Thus, the study proposes taking a closer look at pupils' external representations concerning DC-circuit phenomena.

Factors affecting graft survival within 1-year post-transplantation in heart and lung transplant: an analysis of the OPTN/UNOS registry.

PubMed

Ohe, Hidenori

2012-01-01

Today, a main focus of the transplant community is the long-term outcomes of lung and heart allograft recipients. However, even early post-transplant survival (within the first post-transplant year) needs improvement, as early graft failure still accounts for many allograft losses. In this chapter, we review the experience of heart and lung transplantation as reported to the Organ Procurement Transplant Network/United Network of Organ Sharing registry and investigate the factors responsible for causing failure in the first post-transplant year. Trends indicate that sicker patients are increasingly being transplanted, thereby limiting improvements in early post-transplant survival. More lung and heart transplant patients are coming to transplant on dialysis. In heart transplant, there is an increase in the number of heart retransplant patients and an increase in patients on extracorporeal membrane oxygenation. For lung transplant, more patients are on a ventilator prior to transplant than in the past 25 years. Given that sicker/riskier patients are now receiving more heart and lung transplants, future studies need to take place to better understand these patients so that they can have the same survival as patients entering transplant with less severe illnesses.

Turnout in Classical Dance: Is It Possible to Enhance the External Rotation of the Lower Limb by a Myofascial Manipulation? A Pilot Study.

PubMed

Lohr, Christine; Schmidt, Tobias

2017-12-15

Turnout in classical dance refers to the external rotation of the lower extremities so that the longitudinal axes of the feet form an angle of up to 180°. To what extent a myofascial manipulation (myofascial release, MFR) could enhance this external rotation is as yet unknown. In this pilot study, 16 students of dance and 3 dance instructors were randomly assigned to an intervention group (IG; N = 10) and a group of controls (CG; N = 9). Isolated external hip rotation (EHR) and functional turnout (TO) were evaluated three times (pre-, post-, and follow-up measurement) using a plurimeter and Functional Footprints® rotation discs. In addition, subjectively perceived physical flexibility (PPF) was determined by means of a written survey. The interval between pre- and post-measurement and between post- and follow-up measurement was 4 weeks. Only the IG received four 20-minute MFR treatments of the lower limb at weekly intervals between pre- and post-measurement. In both the post-measurement (pre- versus post-: p = 0.038, d = 0.77) and the follow-up measurement (pre- versus follow-up: p < 0.001, d = 1.66) the IG showed a significantly improved isolated EHR of the right hip and a significantly increased PPF (pre- versus post-: p = 0.047, d = 0.73; pre- versus follow-up: p = 0.012, d = 1.00). The left EHR as well as the right and left TO were not affected by the intervention. It was demonstrated that four sessions of MFR of the lower limb can induce an improvement in the isolated external hip rotation (right hip). The beneficial effects of the treatment regarding an improvement of functional turnout could not be entirely verified in this pilot study. However, the significant increase in the participants' subjective flexibility supports the promising trend in the objective parameters and emphasizes the need to undertake further research.

Embedded wisdom or rooted problems? Aid workers' perspectives on local social and political infrastructure in post-tsunami Aceh.

This paper analyses the role of local social, cultural, and political institutions in post-disaster reconstruction projects. It contends that such institutions are important considerations within community-driven reconstruction initiatives, but are often viewed with ambivalence by external aid organisations. This paper draws upon in-depth qualitative interviews with aid workers involved in the post-tsunami reconstruction in Aceh, Indonesia, to establish: (i) what roles community institutions were suited to play in the reconstruction; (ii) what were the limitations of community institutions when engaging with external aid agencies; (iii) how did external aid agencies engage with local community institutions; and (iv) how did external aid agencies perceive community institutions. © 2015 The Author(s).

The study investigated the impact of psychiatric disorders on Quality of Life (QOL) cross-sectionally and longitudinally in a group of Norwegian tourists severely exposed to the 2004 tsunami. Sixty-two adult Norwegian tsunami survivors were interviewed face to face 2 years post-tsunami (T1) and 58 were interviewed again by telephone 6 years post-tsunami (T2). The majority (81 %) reported direct exposure to the waves, and 14 participants (23 %) lost a close family member in the tsunami. Psychiatric morbidity was measured by structured clinical interviews and QOL was assessed with WHO's Quality of Life-Bref scale. Multiple linear regression analyses were performed to assess the independent effects of psychiatric disorders on QOL 2 and 6 years after the tsunami. Psychiatric disorders, especially depression, but also PTSD and other anxiety disorders, were associated with reduced QOL. Psychiatric disorders were more strongly related to QOL at 6 years after the tsunami than at 2 years. Psychiatric disorders, and especially depression, is related to reduced QOL in a disaster exposed population. Post-disaster psychiatric disorders, such as PTSD and especially depression, should be addressed properly in the aftermath of disasters.

To examine the prevalence of post-traumatic stress disorder symptoms and to explore the predictive factors of post-traumatic stress disorder symptoms among bereaved adolescents four years after the Yushu earthquake. On 14 April 2010, the 7·1-magnitude Yushu earthquake occurred in the high-altitude, hypoxia-prone regions primarily inhabited by ethnic minorities. Many adolescents lost their parents during the earthquake. This study examined post-traumatic stress disorder and its predictors among bereaved Tibetan adolescents four years after the trauma in China. This was a cross-sectional descriptive study. This study used a cross-sectional design with 830 bereaved adolescents. Participant demographic data included gender, age and grade, and the earthquake exposure variables included the deceased relatives, whether they were buried, injured or amputated (non-life-threatening) and whether they witnessed a burial, injury or death. The post-traumatic stress disorder Checklist-Civilian version was used to assess the symptoms and prevalence of post-traumatic stress disorder, and the Coping Style Scale assessed coping styles. The results indicated that the prevalence of post-traumatic stress disorder was 19·3%. Individuals who were buried, injured or amputated (non-life-threatening), who witnessed a burial, injury or death, who suffered severe property loss during the earthquake and who had negative coping skills were the most likely individuals to have post-traumatic stress disorder symptoms. The presence of post-traumatic stress disorder was very prevalent among adolescents four years after the Yushu earthquake. Effective mental health services should be developed to facilitate postdisaster recovery for bereaved adolescents at high risk for post-traumatic stress disorder. The findings in this study improve our understanding of post-traumatic stress disorder and related risk factors in bereaved adolescents in non-Western communities, providing useful information for

The aim was to investigate the contribution of familial risk to externalizing behaviors (FR-EXT), perceived parenting styles, and their interactions to the prediction of externalizing behaviors in preadolescents. Participants were preadolescents aged 10-12 years who participated in TRAILS, a large prospective population-based cohort study in the Netherlands (N = 2,230). Regression analyses were used to determine the relative contribution of FR-EXT and perceived parenting styles to parent and teacher ratings of externalizing behaviors. FR-EXT was based on lifetime parental externalizing psychopathology and the different parenting styles (emotional warmth, rejection, and overprotection) were based on the child's perspective. We also investigated whether different dimensions of perceived parenting styles had different effects on subdomains of externalizing behavior. We found main effects for FR-EXT (vs. no FR-EXT), emotional warmth, rejection, and overprotection that were fairly consistent across rater and outcome measures. More specific, emotional warmth was the most consistent predictor of all outcome measures, and rejection was a stronger predictor of aggression and delinquency than of inattention. Interaction effects were found for FR-EXT and perceived parental rejection and overprotection; other interactions between FR-EXT and parenting styles were not significant. Correlations between FR-EXT and perceived parenting styles were absent or very low and were without clinical significance. Predominantly main effects of FR-EXT and perceived parenting styles independently contribute to externalizing behaviors in preadolescents, suggesting FR-EXT and parenting styles to be two separate areas of causality. The relative lack of gene-environment interactions may be due to the epidemiological nature of the study, the preadolescent age of the subjects, the measurement level of parenting and the measurement level of FR-EXT, which might be a consequence of both genetic and

We report a case of embolomycotic aneurysm of the right iliac artery secondary to bacterial endocarditis. The patient, a 33-year-old woman, presented with unilateral hydronephrosis and lower extremity edema caused by aneurysmal compression of the ipsilateral ureter and the external iliac vein. She was treated with ligation and an extraperitoneal left-external-iliac-artery to right-femoral-artery bypass using a knitted Dacron prosthesis. Since her surgery, our patient has been well except for persistence of moderate leg edema. To the best of our knowledge, we are reporting the 1st case of embolomycotic external-iliac-artery aneurysm secondary to bacterial endocarditis and resulting in hydronephrosis and venous insufficiency.

The aim of this study was to assess the potential for heat production when intra-radicular posts were subjected to ultrasonic vibration. Thirty zirconium ceramic posts and thirty stainless steel posts were luted into canine roots. Ultrasonic vibration was applied to the top of each post for thirty minutes and temperature change on the root surface was measured. The mean peak temperature rise from baseline was 18.7 degrees C. Post type had no influence on peak temperature. Temperature increase on the external root surfaces increased as the thickness of dentine between post and root surface reduced.

Scientific data about the long-term survival of teeth treated with cast post and cores are scarce. Retrospective studies often use different target events for their analyses. A comparison is therefore complicated. For associated tooth-, jaw-, and patient-related factors little evidence exists as to their effect on survival. The purpose of this study was to extend the knowledge on the survival of teeth treated with cast post and cores for observation periods of more than 10 years. A decrease or increase in survival times according to the presence or absence of associated parameters needs to be evaluated. A retrospective evaluation was conducted of all cast post and cores inserted in 1 university clinic between January 1992 and June 2011. A Kaplan-Meier survival analysis was carried out by using extraction as the target event. The survival curves for different tooth types, the presence or absence of adjacent teeth, and the prosthetic restoration of the respective jaws were compared by using the log-rank test (α=.05). A Cox regression model was calculated for multivariate analyses. A total of 717 cast post and cores for 343 patients were recorded. The mean survival time was 13.5 years. A statistically significant decrease in survival times was found for canines (11.9 years) and premolars (13.4 years) versus molars (14.1 years), no adjacent teeth (10.6 years) versus at least 1 adjacent tooth (13.8 years), and the restoration with removable dental prostheses (12.5 years) versus fixed dental prostheses and single crowns (13.9 years). The largest reduction in survival time was found for teeth being used as an abutment for a double crown-retained removable partial dental prosthesis (telescopic denture) (9.8 years). Tooth type and adjacent tooth status remained as significant variables within the multivariate Cox regression model. Cast post and cores have an acceptable long-term survival time. Because different factors may influence survival, considering these factors in

In Ireland, new science curricula were introduced at primary and early post-primary levels in 2003, in an effort to reverse declining interest and enrolment in science. This paper reports on a national study that explored first year post-primary students' experiences of and attitudes towards school science under these new curricula. Data were gathered from 366 pupils using survey and case study approaches. Findings revealed broadly positive attitudes towards post-primary school science, especially the experimental work that is at the heart of the new curriculum. However, it would appear that students were not conducting open-ended investigations or using information and communications technology [ICT] to any great extent; moreover, there was some evidence of traditional teaching methods being utilised. Pupils were highly critical of previous primary school science experiences, reporting a lack of `hands-on' activities, didactic methodologies and, for a significant minority, a paucity of any memorable primary science at all. Improvements in curricular implementation are proposed.

The probabilistic external events analysis performed for the Savannah River Site K-reactor PRA considered many different events which are generally perceived to be external'' to the reactor and its systems, such as fires, floods, seismic events, and transportation accidents (as well as many others). Events which have been shown to be significant contributors to risk include seismic events, tornados, a crane failure scenario, fires and dam failures. The total contribution to the core melt frequency from external initiators has been found to be 2.2 {times} 10{sup {minus}4} per year, from which seismic events are the major contributor (1.2 {times} 10{supmore » {minus}4} per year). Fire initiated events contribute 1.4 {times} 10{sup {minus}7} per year, tornados 5.8 {times} 10{sup {minus}7} per year, dam failures 1.5 {times} 10{sup {minus}6} per year and the crane failure scenario less than 10{sup {minus}4} per year to the core melt frequency. 8 refs., 3 figs., 5 tabs.« less

Background: Post traumatic growth (PTG) can be defined as positive change following a traumatic event. The current conceptualization of PTG encompasses five main dimensions, however, there is no dimension which accounts for the distinct effect of a physical trauma on PTG. The purpose of the present research was to test the role of PTG, physical post traumatic growth (PPTG), resilience and mindfulness in predicting psychological and health related adjustment. Method: Ethical approval was obtained from relevant institutional ethics committees. Participants ( N = 241), who were at least 1 year post prostate cancer treatment, were invited to complete a battery of questionnaires either through an online survey or a paper and pencil package received in the post The sample ranged in age from 44 to 88 years ( M = 64.02, SD = 7.76). Data were analysis using confirmatory factor analysis and structural equation modeling. Results: The physical post traumatic growth inventory (P-PTGI) was used to evaluate the role of PPTG in predicting adjustment using structural equation modeling. P-PTGI predicted lower distress and improvement of quality of life, whereas conversely, the traditional PTG measure was linked with poor adjustment. The relationship between resilience and adjustment was found to be mediated by P-PTGI. Conclusion: Findings suggest the central role of PTG in the prostate cancer survivorship experience is enhanced by the inclusion of PPTG. Adjusting to a physical trauma such as illness (internal transgressor) is unlike a trauma with an external transgressor as the physical trauma creates an entirely different framework for adjustment. The current study demonstrates the impact of PPTG on adjustment. This significantly adds to the theory of the development of PTG by highlighting the interplay of resilience with PTG, PPTG, and adjustment.

The purpose of this study was to investigate the potential for temperature increase along the external root surface during ultrasonic post removal in a simulated clinical environment. Thirty-seven extracted teeth were decoronated, instrumented, and then obturated with gutta-percha and sealer. Post spaces were prepared, followed by cementation of stainless steel posts. A simulated clinical environment was created by using a polymethylmethacrylate sheet with holes custom fitted for the extracted teeth and then suspended over a heated water bath. Two thermocouples were attached at 6 and 12 mm from the top of the post along the external root surface. Teeth were divided into 3 test groups, no coolant, air-cooled, and water-cooled. Temperature changes were recorded by using a Vishay 5000 Strain Smart system. Results demonstrated that a significant difference existed in the average heat rates between the upper and lower thermocouples for no coolant and water-cooled groups at the medium setting and the air-cooled group at the high setting. The average heat rates were significantly different between the 2 thermocouples for all 3 groups when comparing the 2 ultrasonic power settings. Results indicated that the average heat rate was less for the water-cooled group when using a medium power setting.

Understanding young adult physical activity, alcohol and tobacco use in community colleges and 4-year post-secondary institutions: A cross-sectional analysis of epidemiological surveillance data

Background Young adults experience many adverse health behavior changes as they transition from adolescence into adulthood. A better understanding of the relationships between health promoting and risky health behaviors may aid in the development of health promotion interventions for various types of young adult post-secondary students. Therefore, the purpose of this study was to examine associations between alcohol and tobacco use and physical activity among 2-year and 4-year college students. Methods Cross-sectional analyses were conducted using 2007 survey data, collected as part of an on-going post-secondary health surveillance system in Minnesota. Students were randomly selected to participant from 14 Minnesota colleges and universities (six 2-year community and/or technical colleges, eight 4-year post-secondary institutions). The 2007 surveillance data included 9,931 respondents. Results The prevalence of demographic characteristics and health behaviors (e.g., physical activity, tobacco use) differed between young adults attending 2-year and 4-year post-secondary institutions; in general, those attending 2-year institutions are representative of more at-risk populations. Overall, higher levels of moderate, vigorous and strengthening physical activity were associated with higher levels of alcohol consumption and lower levels of smoking. In general, despite the disparities in the prevalence of these risk behaviors, the associations between the behaviors did not differ substantially between 2-year and 4-year post-secondary populations. Conclusions These findings illustrate links between leading risk behaviors. Interventions targeting multiple risk behaviors among young adults may warrant further consideration. Overall, future research is needed to support and inform young adult health promotion efforts that may be implemented in a wide array of post-secondary institutions. PMID:20420678

To estimate the prevalence of jaw symptoms and signs during the first year after a neck sprain in a car collision. Further, to determine their relationships to the localisation and grade of the initial neck symptoms and signs, headache, post-traumatic stress and crash characteristics. One hundred and forty-six adult subjects and crash characteristics were prospectively investigated in an in-depth study during 1997-2001. Head, neck, and jaw symptoms and signs were recorded within 5 weeks and after 1 year. Acute post-traumatic stress was estimated with the Impact of Event Scale-Revised (IES-R). Jaw symptoms were initially reported by three men (5%) and three women (4%), and subsequently developed in eight women (10%) during the following year. Jaw signs were noted initially in 53 subjects (37%) and in 28 subjects (24%) after 1 year, without difference between sexes, and more often after low-speed impacts. Headache in females, cranial cervical symptoms, pronounced neck problems, post-traumatic stress and whiplash-associated disorders (WAD) grade II-III after rear-end impacts were related to jaw signs during the acute phase. After 1 year, jaw signs were related to residual neck problems, headache and post-traumatic stress. Jaw symptoms are seldom reported during the acute phase after a whiplash trauma. Women more often than men develop jaw symptoms during the first year. Jaw symptoms and signs may develop also after low-speed impacts, especially after rear-end collisions. Jaw symptoms and signs should be observed after whiplash trauma, especially in those with headache, pronounced neck problems, cranial neck symptoms and post-traumatic stress.

Knee arthrodesis may be the last possible option for infected total knee arthroplasty (TKA) patients and in revision cases involving severe bone loss and/or extensor mechanism damages. Success in these situations depends on achieving good fixation assembly stability. We report bone fusion results using a fixation technique combining cross-pinning by two Steinman pins with a single-frame external fixator. Remission of infection at long-term follow-up was an additional criteria assessed for those cases initially treated for sepsis. This fixation modality improves fusion rates. In six of this series of eight patients (mean age: 59 years), surgery was performed in a context of infection: five cases of infected TKA, and one case of septic arthritis. In the other two cases, arthrodesis was respectively indicated for a severe post-traumatic stiffness compounded by extensor system rupture and for a fracture combined to a complete mechanical implant loosening. In three of the six infection cases, arthrodesis was performed as a single-stage procedure. All patients were operated on using the same technique: primary arthrodesis site stabilization by frontal cross-pinning with two Steinman pins, followed by installation of a sagittal external fixator frame. Results were assessed at a mean 8 year follow-up. All the arthrodeses showed fusion at a mean 3.5 months (range: 2.5 to 6 months) postoperative delay without reintervention. Weight-bearing was resumed at 2 to 3 months. The external fixator was removed at a mean 5.2 months. No recurrence of infection was observed over a mean follow-up of 8.2 years (range: 1 to 15 years). Three complications occurred: one hematoma, managed surgically; one supracondylar fracture treated orthopedically; and one osteitis, managed by surgical curettage. This knee arthrodesis technique proved effective, with no failures in this short series, especially in cases of primary infection. It is a reproducible means of osteosynthesis, with little

On December 26, 2004, the tsunami destroyed many families, communities, and residential areas. Adverse psychological impact on children and adolescents due to a natural disaster of this magnitude has never been reported in Thailand's history particularly as Post-Traumatic Stress Disorder (PTSD). Investigate clinical symptoms and develop a 2-year monitoring and intervention program for PTSD in children affected by the December 26, 2004 tsunami natural disaster The study period started six weeks after the event and was completed after two years. One thousand six hundred and twenty five surviving students from two schools in Takuapa district, Phang-nga Province, were enrolled. Screening tests using Pediatric symptom checklists, Childhood depressive intervention (CDI), and Revised child impact of events scales (CRIES) were done. Psychiatric evaluations were done by child and adolescent psychiatrists. Post Traumatic Stress Disorder (PTSD) was diagnosed using criteria from Diagnostic and Statistical Manual of Mental Disorders, 4th edition. The prevalence of PSTD in the affected students were 57.3, 46.1, 31.6, 10.4, and 7.6% at 6 weeks, 6 months, 1 year, 1 1/2 years, and 2 years, respectively. The female: male ratio was 1.7:1. The peak age was 9-10 years old. Threatened situations were studied. Of the 176 students who risked their lives in the waves, 48 (27.3%) suffered from PTSD. Meanwhile, of the 1314 students who were not hit by the waves but were among affected friends and relatives, 42 students (3.1%) suffered from PTSD. The prevalence of PTSD in those hit by the waves were significantly higher than those who were not [p-value < 0.01, RR = 5.16 (4.04-.6.6)]. The prevalence of PSTD in children who suffered from the tsunami disaster was as high as 57.3% at six weeks after the incident. It declined sharply at two years (7.6%) with the help of integrated welfare. The children continue to get financial, rehabilitation, and mental health support to prevent long

Prior studies have shown that birth complications interact with psychosocial risk factors in predisposing to increased externalizing behavior in childhood and criminal behavior in adulthood. However, little is known about the direct relationship between birth complications and externalizing behavior. Furthermore, the mechanism by which the birth complications predispose to externalizing behavior is not well explored. This study aims to assess whether birth complications predispose to early adolescent externalizing behavior and to test whether Intelligence Quotient (IQ) mediates relationships between predictor and outcome variables. We used data from a prospective, longitudinal birth cohort of 1,795 3-year-old boys and girls from Mauritius to test hypotheses. Birth complications were assessed from hospital record data, malnutrition from a pediatric exam at age 3 years, psychosocial adversity from parental interviews at age 3 years, and externalizing behavior problems from parental ratings at age 11 years. We found that babies with birth complications are more likely to develop externalizing behavior problems at age 11. Low IQ was associated with birth complications and was found to mediate the link between early predictors and later externalizing behavior. These prospective, longitudinal findings have potential clinical implications for the identification of early adolescent externalizing behavior and for public health attempts to prevent the occurrence of child externalizing behavior problems.

The aim of the study was to determine whether final year medical students in medical schools of south-east Nigeria were satisfied with rural community posting. A cross-sectional descriptive study design was used. All final year medical students in the six medical schools in south-east Nigeria who had completed their rural community posting and were willing to participate were included in the study. The students were interviewed using a pretested, self-administered questionnaire. A total of 457 medical students participated in the study, representing a response rate of 86.7%. Only a minor proportion of the students (22.5%) were satisfied with rural community posting. The most common reason for dissatisfaction among the students was lack of interest in rural communities. Most students (68.7%) were of the opinion that a good rural community posting could influence the students to practise in a rural area after graduation. Factors associated with satisfaction with rural community posting included being a student in a federal institution (adjusted odds ratio (AOR)=0.6, 95% confidence interval (CI)=0.4-0.9), being a male student (AOR=2.4, 95%CI=1.5-3.9) and intention to specialize in community medicine after graduation (AOR=2.7, 95%CI=1.2-6.0). Most students were dissatisfied with rural community postings and the major reason for dissatisfaction was lack of interest in rural communities. A properly organized rural community posting is capable of changing the negative attitude of the students towards life and medical practice in the rural area. Adequate orientation of the students on the relevance of the posting, good community exposure and enhanced student lecturer interactions during the posting period could ensure satisfaction of the students. There should be a targeted evaluation of the rural community posting at the various medical schools in the country with the aim of strengthening and modifying the posting where necessary so as to ensure its purpose is realized.

Background Poor sleep quality (SQ) is common after solid organ transplantation; however, very little is known about its natural history. We assessed the changes in SQ from pre- to 3 years post-transplant in adult heart, kidney, liver and lung recipients included in the prospective nation-wide Swiss Transplant Cohort Study. We explored associations with selected variables in patients suffering persistent poor SQ compared to those with good or variable SQ. Methods Adult single organ transplant recipients enrolled in the Swiss Transplant Cohort Study with pre-transplant and at least 3 post-transplant SQ assessment data were included. SQ was self-reported pre-transplant (at listing), then at 6, 12, 24 and 36 months post-transplant. A single SQ item was used to identify poor (0–5) and good sleepers (6–10). Between organ groups, SQ was compared via logistic regression analysis with generalized estimating equations. Within the group reporting persistently poor SQ, we used logistic regression or Kaplan-Meier analysis as appropriate to check for differences in global quality of life and survival. Results In a sample of 1173 transplant patients (age: 52.1±13.2 years; 65% males; 66% kidney, 17% liver, 10% lung, 7% heart) transplanted between 2008 and 2012, pre- transplant poor SQ was highest in liver (50%) and heart (49%) recipients. Overall, poor SQ decreased significantly from pre-transplant (38%) to 24 months post-transplant (26%) and remained stable at 3 years (29%). Patients reporting persistently poor SQ had significantly more depressive symptomatology and lower global quality of life. Conclusion Because self-reported poor SQ is related to poorer global quality of life, these results emphasize the need for further studies to find suitable treatment options for poor SQ in transplant recipients.

AIM To examine the long-term effects induced by treatment with the function regulator (FR-2) appliance 7 years post-treatment compared with untreated class II subjects. SUBJECTS AND METHODS The FR-2 sample was collected prospectively and comprised 17 subjects (10 boys and 7 girls, mean age 10.8 years) who were treated with the FR-2 appliance for 1.7 years and re-evaluated 7.1 years after treatment. The step-by-step mandibular advancement was performed gradually (increments up to 3–4 mm), until a ‘super class I’ molar relationship was obtained. The control group consisted of 17 class II subjects (9 boys and 8 girls, mean age 11.3 years) with class II malocclusion, excessive overjet, and class II molar relationship, matched to the treated group as to ages at all times, gender distribution, and stages of skeletal maturity (evaluated by the cervical vertebral maturation method). The lateral cephalograms were analysed at T1 (initial), T2 (final), and T3 (7.1 years post-treatment). The compatibility between the groups and the comparisons of their changes at T1–T2, T2–T3, and T1–T3 intervals were examined by independent sample t-tests (P < 0.05). RESULTS FR-2 treatment provided a significant improvement in the maxillomandibular relationship due to an increase in mandibular length compared with controls, which remained stable over time. Also overjet, overbite, and molar relationship corrections demonstrated stability. Among dentoalveolar changes, only the increased mesial movement of the mandibular molars in the FR-2 group demonstrated stability. CONCLUSIONS Correction of class II malocclusion remained stable 7 years after FR-2 treatment mainly due to the stability of the skeletal changes. PMID:23736378

In developing countries, due to limited availability of modern anesthesia and overcrowding of the hospitals with patients who need surgery, high-risk patients with "intertrochanteric" fractures remain unsuita ble for open reduction and internal fixation.The aim of this study was to analyze the results of external fixation of "intertrochanteric" fractures in high-risk geriatric patients in a developing country.The results of 62 ambulatory high-risk geriatric patients with a mean age of 70 years (range 58-90 years) with "intertrochanteric" fractures, in whom external fixation was performed, are reported.Eight patients died during follow-up due to medical causes unrelated to the surgical procedure. So only 54 patients were available for final assessment. Procedure is simple, performed under local anesthesia, requires less time for surgery and is associated with less blood loss. Good fixation and early ambulation was achieved in most of the patients. Average time to union was 14 weeks. Thirty-one patients developed superficial pin tract infection and 28 patients had average shortening of 15 mm due to impaction and varus angulation. Functional outcome was assessed using Judet's point system. Good to excellent results were achieved in 44 patients.This study demonstrated that external fixation of "intertrochantric" fractures performed under local anesthesia offers significant advantage in ambulatory high-risk geriatric patients especially in a developing country.

Prior research has demonstrated both socialization and selection effects for the relationship between antisocial peer affiliation and externalizing problems in adolescence. Less research has evaluated such effects post-adolescence. In this study, a cross-lagged panel analysis was used to evaluate the extent of socialization (i.e., the effect of antisocial peer affiliation on subsequent externalizing disorders) and selection (i.e., the effect of externalizing disorders on subsequent antisocial peer affiliation) in the prospective relationships between antisocial peer affiliation and externalizing disorders from adolescence through young adulthood. Data from a community sample of 2,769 individuals (52% female) with assessments at ages 17, 20, 24, and 29 were used. Analyses with a latent externalizing measure (estimated using clinical symptom counts of nicotine dependence, alcohol use disorder, illicit drug use disorder, and adult antisocial behavior) and self-reported antisocial peer affiliation revealed significantly stronger socialization effects from age 17 to 20, followed by significantly stronger selection effects from age 20 to 24 and 24 to 29. To better understand the impact of college experience, moderation by college status was evaluated at each developmental transition. Results were generally consistent for those who were in or were not in college. Results suggest selection effects are more important in later developmental periods than earlier periods, particularly in relation to an overall liability towards externalizing disorders, likely due to more freedom in peer selection post-adolescence.

To assess and compare post-traumatic osteoarthritis following intra-articular calcaneal fractures, one must have a reliable grading system that consistently grades the post-traumatic changes of the joint. A reliable grading system aids in the communication between treating physicians and improves the interpretation of research. To date, there is no consensus on what grading system to use in the evaluation of post-traumatic subtalar osteoarthritis. The objective of this study was to determine and compare the inter- and intra-rater reliability of two grading systems for post-traumatic subtalar osteoarthritis. Four observers evaluated 50 calcaneal fractures at least one year after trauma on conventional oblique lateral, internally and externally rotated views, and graded post-traumatic subtalar osteoarthritis using the Kellgren and Lawrence Grading Scale (KLGS) and the Paley Grading System (PGS). Inter- and intra-rater reliability were calculated and compared. The inter-rater reliability showed an intra-class correlation (ICC) of 0.54 (95 % CI 0.40-0.67) for the KLGS and an ICC of 0.41 (95 % CI 0.26 - 0.57) for the PGS. This difference was not statistically significant. The intra-rater reliability showed a mean weighted kappa of 0.62 for both the KLGS and the PGS. There is no statistically significant difference in reliability between the Kellgren and Lawrence Grading System (KLGS) and the Paley Grading System (PGS). The PGS allows for an easy two-step approach making it easy for everyday clinical purposes. For research purposes however, the more detailed and widely used KLGS seems preferable.

The aim of this study was to verify the efficacy of two pencil-and-paper trainings empowering numerical and visuo-spatial abilities in Italian five-year-old kindergarteners. Specifically, the trainings were respectively carried out by the curricular teacher or by an external trainer. The former received a specific training in order to use the psychoeducational programmes with her pupils, whereas the latter received a specific education about the role of numerical and visuo-spatial abilities for school achievement and she was also trained to use psychoeducational trainings in kindergarten schools. At pre-test and post-test nonverbal functions and numeracy knowledge were assessed through a battery of standardized tests. The results show that both the numerical psychoeducational programme and the visuo-spatial one are useful tools to enhance mathematical achievements in kindergarteners. However, when the trainings were proposed by the external trainer, the efficacy of the psychoeducational programmes was more significant. These outcomes seem to be related both to the expertise and the novelty effect of the external trainer on the classroom.

Information-Constrained Optima with Retrading: An Externality and Its Market-Based Solution☆

PubMed Central

Kilenthong, Weerachart T.; Townsend, Robert M.

2010-01-01

This paper studies the efficiency of competitive equilibria in environments with a moral hazard problem and unobserved states, both with retrading in ex post spot markets. The interaction between private information problems and the possibility of retrade creates an externality, unless preferences have special, restrictive properties. The externality is internalized by allowing agents to contract ex ante on market fundamentals determining the spot price or interest rate, over and above contracting on actions and outputs. Then competitive equilibria are equivalent with the appropriate notion of constrained Pareto optimality. Examples show that it is possible to have multiple market fundamentals or price-islands, created endogenously in equilibrium. PMID:21765540

Post-traumatic brain injury fatigue (PTBIF) is a major problem in the years after traumatic brain injury (TBI), yet little is known about its persistence and resolution. The objective of the study was to identify factors related to PTBIF remission and resolution. TBI Model System registrants at five centres participated in interviews at either one and two years post-injury (Y1-2 Cohort), or two and five years post-injury (Y2-5 Cohort). Characteristics of participants with PTBIF remission were compared to those with PTBIF persistence. Variables studied included the presence of and changes in disability, sleep dysfunction, mood, and community participation. The Functional Independence Measure did not differ significantly between groups or over time. In the Y1-2 Cohort the Fatigue Resolved group scored significantly better on the Disability Rating Scale and Pittsburgh Sleep Quality Index. In the Y2-5 Cohort the Fatigue Resolved group scored significantly higher on a measure of community participation. It was concluded that fewer than half of the sample in each cohort experienced a remission of PTBIF between time points. Persistence of PTBIF 1-2 years post-injury is associated with disability, sleep disturbance, and depression while persistence of fatigue beyond 2 years post-injury appears to be related to participation level, underscoring the potential impact of effective surveillance, assessment, and treatment of this condition in optimising life after TBI. Differences in fatigue progression may point to the presence of different types of PTBIF.

Acute myeloid leukaemia mainly affects elderly people, with a median age at diagnosis of around 70 years. Although about 50-60% of patients enter first complete remission upon intensive induction chemotherapy, relapse remains high and overall outcomes are disappointing. Therefore, effective post-remission therapy is urgently needed. Although often no post-remission therapy is given to elderly patients, it might include chemotherapy or allogeneic haemopoietic stem cell transplantation (HSCT) following reduced-intensity conditioning. We aimed to assess the comparative value of allogeneic HSCT with other approaches, including no post-remission therapy, in patients with acute myeloid leukaemia aged 60 years and older. For this time-dependent analysis, we used the results from four successive prospective HOVON-SAKK acute myeloid leukaemia trials. Between May 3, 2001, and Feb 5, 2010, a total of 1155 patients aged 60 years and older were entered into these trials, of whom 640 obtained a first complete remission after induction chemotherapy and were included in the analysis. Post-remission therapy consisted of allogeneic HSCT following reduced-intensity conditioning (n=97), gemtuzumab ozogamicin (n=110), chemotherapy (n=44), autologous HSCT (n=23), or no further treatment (n=366). Reduced-intensity conditioning regimens consisted of fludarabine combined with 2 Gy of total body irradiation (n=71), fludarabine with busulfan (n=10), or other regimens (n=16). A time-dependent analysis was done, in which allogeneic HSCT was compared with other types of post-remission therapy. The primary endpoint of the study was 5-year overall survival for all treatment groups, analysed by a time-dependent analysis. 5-year overall survival was 35% (95% CI 25-44) for patients who received an allogeneic HSCT, 21% (17-26) for those who received no additional post-remission therapy, and 26% (19-33) for patients who received either additional chemotherapy or autologous HSCT.

Adaptive plasticity in speech perception: effects of external information and internal predictions

PubMed Central

Guediche, Sara; Fiez, Julie A.; Holt, Lori L.

2016-01-01

When listeners encounter speech under adverse listening conditions, adaptive adjustments in perception can improve comprehension over time. In some cases, these adaptive changes require the presence of external information that disambiguates the distorted speech signals, whereas in other cases mere exposure is sufficient. Both external (e.g. written feedback) and internal (e.g., prior word knowledge) sources of information can be used to generate predictions about the correct mapping of a distorted speech signal. We hypothesize that these predictions provide a basis for determining the discrepancy between the expected and actual speech signal that can be used to guide adaptive changes in perception. This study provides the first empirical investigation that manipulates external and internal factors through 1) the availability of explicit external disambiguating information via the presence or absence of post-response orthographic information paired with a repetition of the degraded stimulus, and 2) the accuracy of internally-generated predictions; an acoustic distortion is introduced either abruptly or incrementally. The results demonstrate that the impact of external information on adaptive plasticity is contingent upon whether the intelligibility of the stimuli permits accurate internally-generated predictions during exposure. External information sources enhance adaptive plasticity only when input signals are severely degraded and cannot reliably access internal predictions. This is consistent with a computational framework for adaptive plasticity in which error-driven supervised learning relies on the ability to compute sensory prediction error signals from both internal and external sources of information.

First branchial cleft anomalies are rare with the average age of presentation as 19 years. There is an average delay of 3.5 years between initial presentation and adequate treatment due to diagnostic dilemma. A very rare variant of first branchial cleft anomaly presenting as a post-auricular salivary fistula is reported. A 12-year-old girl presented with a history of intermittent watery discharge, more so at the time of meals from a right post-auricular opening for last 3 years. Computed tomography sialography revealed a fistulous tract connecting the sub segmental duct of the parotid gland extending along the pre-tragus region in subcutaneous plane up to mastoid tip after passing inferior to external auditory canal. Superficial parotidectomy with identification of facial nerve branches was carried out for excision of the tract. Histopathology revealed sinus tract comprising of ectodermal components and acini of the parotid gland. We classified our case into work's type-2 based on anatomical location at an angle of mandible, its relationship to parotid gland and facial nerve and previous history of ear discharge. To the best of our knowledge, this is the first case of its type to be reported.

Usually death has to be determined by a physician. Deaths on board of ocean-going vessels confront the crew with special challenges, as on the high seas--especially in the container and cargo ship business--often no physician will be available and death has to be determined by medical laymen such as the captain or the medical officer. To document the determination of death, a "Provisional Certificate of Death on the High Seas" is presented. Moreover, an algorithm "Provisional Post-Mortem Examination on the High Seas" is presented to document the results and the practical performance of the external post-mortem examination by medical laymen on a ship. With the help of concrete procedural instructions medical laymen on board of sea-going vessels are to be enabled to determine the death of a human being beyond doubt, to perform a preliminary external post-mortem examination and to store the corpse according to forensic requirements until the ship reaches a port and the body is delivered to the harbour physician.

External fixation of tibial pilon fractures and fracture healing.

PubMed

Ristiniemi, Jukka

2007-06-01

Distal tibial fractures are rare and difficult to treat because the bones are subcutaneous. External fixation is commonly used, but the method often results in delayed union. The aim of the present study was to find out the factors that affect fracture union in tibial pilon fractures. For this purpose, prospective data collection of tibial pilon fractures was carried out in 1998-2004, resulting in 159 fractures, of which 83 were treated with external fixation. Additionally, 23 open tibial fractures with significant > 3 cm bone defect that were treated with a staged method in 2000-2004 were retrospectively evaluated. The specific questions to be answered were: What are the risk factors for delayed union associated with two-ring hybrid external fixation? Does human recombinant BMP-7 accelerate healing? What is the role of temporary ankle-spanning external fixation? What is the healing potential of distal tibial bone loss treated with a staged method using antibiotic beads and subsequent autogenous cancellous grafting compared to other locations of the tibia? The following risk factors for delayed healing after external fixation were identified: post-reduction fracture gap of >3 mm and fixation of the associated fibula fracture. Fracture displacement could be better controlled with initial temporary external fixation than with early definitive fixation, but it had no significant effect on healing time, functional outcome or complication rate. Osteoinduction with rhBMP-7 was found to accelerate fracture healing and to shorten the sick leave. A staged method using antibiotic beads and subsequent autogenous cancellous grafting proved to be effective in the treatment of tibial bone loss. Healing potential of the bone loss in distal tibia was at least equally good as in other locations of the tibia.

In India, Breast cancer is now the most common cancer in urban and 2nd most common in rural areas [1]. The incidence is rising, more younger women are getting affected and due to increase in survival rates there is an increase in the total number of women suffering from breast Cancer. So far there are no studies evaluating the pattern of breast prosthesis use in Indian scenario. The aim of this study is to address the patterns of external breast prosthesis used in India and view of Indian women on such prosthesis after mastectomy for breast cancer. This was a descriptive longitudinal study. In this study we interviewed (telephonic) 63 people, after three years of completing treatment under The Department of Surgical Oncology, St. Johns medical college, Bangalore. Among the study group, 27 members (40 %) were using various prosthesis, rest 36 women were not using any type of prosthesis. Among the users of prosthesis, silicon prosthesis was used by 6 women, padded cups by 8 women, cloth or cotton by 12 women and 1 woman used other type of prosthesis. Most women use simple items like cloth and cotton (44 %). Next most commonly used prosthesis are padded cups(). Only 22 % of women were found using silicon prosthesis in this study. Most of the well educated patients used external prosthesis either in the form of silicon prosthesis or padded cups. Most of women below age of 50 used external breast prosthesis. Use of prosthesis was more in urban compared to rural population (48 % vs 25 %). Prosthesis users worried more about the body image than women not using prosthesis. 25 % of women using prosthesis had body image issues where as only 5 % of non prosthesis users had such problems. Prosthesis users need improvement in terms of comfort, size, shape and affordability. Most common reasons for not using prosthesis are age, lack of motivation and awareness. Less than half of the women included in this study used external prosthesis after mastectomy for breast cancer

Fronto-amygdalar networks are implicated in childhood psychiatric disorders characterized by high rates of externalizing (aggressive, noncompliant, oppositional) behavior. Although externalizing behaviors are distributed continuously across clinical and nonclinical samples, little is known about how brain variations may confer risk for problematic behavior. Here, we studied cortical thickness, amygdala volume, and cortico-amygdalar network correlates of externalizing behavior in a large sample of healthy children. Two hundred ninety-seven healthy children (6-18 years; mean = 12 ± 3 years), with 517 magnetic resonance imaging scans, from the National Institutes of Health Magnetic Resonance Imaging Study of Normal Brain Development, were studied. Relationships between externalizing behaviors (measured with the Child Behavior Checklist) and cortical thickness, amygdala volume, and cortico-amygdalar structural networks were examined using first-order linear mixed-effects models, after controlling for age, sex, scanner, and total brain volume. Results significant at p ≤ .05, following multiple comparison correction, are reported. Left orbitofrontal, right retrosplenial cingulate, and medial temporal cortex thickness were negatively correlated with externalizing behaviors. Although amygdala volume alone was not correlated with externalizing behaviors, an orbitofrontal cortex-amygdala network predicted rates of externalizing behavior. Children with lower levels of externalizing behaviors exhibited positive correlations between orbitofrontal cortex and amygdala structure, while these regions were not correlated in children with higher levels of externalizing behavior. Our findings identify key cortical nodes in frontal, cingulate, and temporal cortex associated with externalizing behaviors in children; and indicate that orbitofrontal-amygdala network properties may influence externalizing behaviors, along a continuum and across healthy and clinical samples.

Post-traumatic stress disorder (PTSD) may present many years after the original trauma. Case studies of two elderly patients are described. Both had experienced life-threatening combat situations and witnessed intense suffering during the Second World War. Marked distress was triggered by the media commemorating the fiftieth anniversary of the end of the war. PTSD patients often avoid talking of their traumatic experiences because of associated distress. Without taking a military and trauma history from elderly patients the diagnosis is likely to be missed.

Liberia remains in transition from a state of humanitarian emergency to development, and Lofa County was the epicentre of recent conflict. This study aimed to estimate mortality and malnutrition and evaluate access to health services, water and sanitation. The survey was conducted in April 2009 and employed a 46 cluster×20 design (n=920 households) with probability proportional to size sampling. The crude mortality rate was 24.3/1000/year (CI: 19.0 to 29.6) or 0.67/10,000/day (CI: 0.52 to 0.81). The global acute malnutrition rate was 7.9% (CI: 5.4 to 8.9), and the severe acute malnutrition rate was 4.5% (CI: 2.9 to 6.7). Access to basic health services was relatively good according to a variety of indicators; however, access to sanitation was low, with 39.5% of households reporting access to toilets or latrines. Despite high rates of displacement and infrastructure destruction, population health appears to be relatively stable 5 years post-conflict, though a continued focus on reconstruction and development is needed.

Anterior cruciate ligament injury results in altered kinematics and kinetics in the knee and hip joints that persist despite surgical reconstruction and rehabilitation. Abnormal movement patterns and a history of osteoarthritis are risk factors for articular cartilage degeneration in additional joints. The purpose of this study was to determine if hip joint biomechanics early after anterior cruciate ligament injury and reconstruction differ between patients with and without post-traumatic knee osteoarthritis 5years after reconstruction. The study's rationale was that individuals who develop knee osteoarthritis after anterior cruciate ligament injury may also demonstrate large alterations in hip joint biomechanics. Nineteen athletes with anterior cruciate ligament injury completed standard gait analysis before (baseline) and after (post-training) extended pre-operative rehabilitation and at 6months, 1year, and 2years after reconstruction. Weightbearing knee radiographs were completed 5years after reconstruction to identify medial compartment osteoarthritis. Five of 19 patients had knee osteoarthritis at 5years after anterior cruciate ligament reconstruction. Patients with knee osteoarthritis at 5years walked with smaller sagittal plane hip angles (P: 0.043) and lower sagittal (P: 0.021) and frontal plane (P: 0.042) external hip moments in the injured limb before and after reconstruction compared to those without knee osteoarthritis. The current findings suggest hip joint biomechanics may be altered in patients who develop post-traumatic knee osteoarthritis. Further study is needed to confirm whether the risk of non-traumatic hip pathology is increased after anterior cruciate ligament injury and if hip joint biomechanics influence its development.

Identifying factors predicting the long-term outcome of participation and autonomy after stroke is essential for developing individualized rehabilitation interventions. The aim was to describe self-assessed participation and autonomy and to explore factors associated with the same at 1 year post stroke. Participants consisted of 79 persons (mean age = 67) with a first-time stroke at the 1-year follow-up. To investigate perceived participation and autonomy at 1 year, a self-assessment questionnaire, the Impact on Participation and Autonomy-English version (IPA-E) was used. Multivariate logistic regression models were performed using age, gender, stroke severity, and functional dependency at discharge as potential contributors to the perceived level of participation and autonomy. A high percentage (70%-88%) evaluated their functions as fair to very good within all domains of the IPA-E at 1 year post stroke. However, around a fifth experienced their Family role as poor to very poor. Participants' functional dependency at discharge significantly influenced the outcome for the domains of Family role (odds ratio [OR] = 5.66, P < .01), Social relations (OR = 3.23, P < .03), and Autonomy indoors (OR = 3.44, P < .04) at 1 year post stroke. Aspects of the Family role domain deserve further attention in interventions aimed at improving participation and autonomy at 1 year post stroke. The results also indicate that supporting indoor autonomy and social relations of persons with stroke during the acute rehabilitation is important to enhance participation and autonomy at 1 year post stroke.

Objective Adolescents sustaining traumatic brain injury (TBI) show increased prevalence of behavior problems. This study investigated the associations of parent mental health, family functioning, and parent–adolescent interaction with adolescent externalizing behavior problems in the initial months after TBI, and examined whether injury severity moderated these associations. Methods 117 parent–adolescent dyads completed measures of family functioning, adolescent behavior, and parent mental health an average of 108 days post-TBI. Dyads also engaged in a 10-min video-recorded problem-solving activity coded for parent behavior and tone of interaction. Results Overall, higher ratings of effective parent communication were associated with fewer externalizing behavior problems, whereas poorer caregiver psychological functioning was associated with greater adolescent externalizing behaviors. Results failed to reveal moderating effects of TBI severity on the relationship between socio-environmental factors and behavior problems. Conclusions Interventions targeting parent communication and/or improving caregiver psychological health may ameliorate potential externalizing behavior problems after adolescent TBI.

To study the efficacy of a new technique of single self-linking silicone stent exclusively in pediatric external dacryocystorhinostomy (DCR) and to report the new use and advantages of endoscopic guidance for the same. Prospective interventional case series, including 11 eyes of ten patients with nasolacrimal duct obstruction. Data collected included demographic data, clinical presentation, laterality, status of lids and puncta, syringing findings, probing interpretations, types and duration of intubation. Consecutive pediatric patients with post-saccal obstruction who underwent an external dacryocystorhinostomy were included. Exclusion criteria included patients who had undergone a DCR in the past by any route via external, endonasal or transcanalicular. Primary outcome measures were stent retention and ease of stent removal. Secondary outcome measures were anatomic patency of the passage and resolution of symptoms. There were three male and seven female patients. Mean age was 9.4 years (range 6-15). A total of 11 procedures were carried out. Following placement of self-linked stents, the removal was done at a mean duration of 13.2 weeks (range:12-16 weeks). None of the patients had a stent prolapse during this period. All stents were removed in the outpatient without the use of general anesthesia with minimal endoscopic guidance. A minimum follow-up of three months following removal was considered for final analysis. Follow-up ranged from three months to six months after tube removal. The anatomical and functional success rate was 91%. There was one anatomical failure three months following tube removal and the remaining patients were free of symptoms at the last follow-up. Self-linking stents are a useful modality in pediatric patients not only to prevent stent prolapse but also to allow easy removal with minimum discomfort. Endoscopic guidance is a useful addition to this technique.

This study investigated whether corporal punishment when the child was two years old predicted child externalizing behaviors a year later, and whether or not this association was moderated by parents' observed behavior towards their child. Data came from 218 couples and their first born child. The frequency of fathers' corporal punishment when the child was two years old predicted child externalizing behaviors a year later, while controlling for initial levels of child externalizing behaviors. Also, observed positive and harsh parenting moderated the relationship between corporal punishment and child externalizing behaviors. These results highlight the importance of continuing to examine the effects of a commonly used form of discipline (i.e., corporal punishment) and the parental climate in which it is used.

Purpose: External beam accelerated partial breast irradiation (APBI) is an increasingly popular technique for treatment of patients with early stage breast cancer following breast-conserving surgery. Here we present 5-year results of a prospective trial. Methods and Materials: From October 2003 through November 2005, 98 evaluable patients with stage I breast cancer were enrolled in the first dose step (32 Gy delivered in 8 twice-daily fractions) of a prospective, multi-institutional, dose escalation clinical trial of 3-dimensional conformal external beam APBI (3D-APBI). Median age was 61 years; median tumor size was 0.8 cm; 89% of tumors were estrogen receptor positive; 10% hadmore » a triple-negative phenotype; and 1% had a HER-2-positive subtype. Median follow-up was 71 months (range, 2-88 months; interquartile range, 64-75 months). Results: Five patients developed ipsilateral breast tumor recurrence (IBTR), for a 5-year actuarial IBTR rate of 5% (95% confidence interval [CI], 1%-10%). Three of these cases occurred in patients with triple-negative disease and 2 in non-triple-negative patients, for 5-year actuarial IBTR rates of 33% (95% CI, 0%-57%) and 2% (95% CI, 0%-6%; P<.0001), respectively. On multivariable analysis, triple-negative phenotype was the only predictor of IBTR, with borderline statistical significance after adjusting for tumor grade (P=.0537). Conclusions: Overall outcomes were excellent, particularly for patients with estrogen receptor-positive disease. Patients in this study with triple-negative breast cancer had a significantly higher IBTR rate than patients with other receptor phenotypes when treated with 3D-APBI. Larger, prospective 3D-APBI clinical trials should continue to evaluate the effect of hormone receptor phenotype on IBTR rates.« less

Using data from two long-term longitudinal projects, we investigated reciprocal relations between maternal reports of physical discipline and teacher and self-ratings of child externalizing behavior, accounting for continuity in both discipline and externalizing over time. In Study 1, which followed a community sample of 562 boys and girls from age 6 to 9, high levels of physical discipline in a given year predicted high levels of externalizing behavior in the next year, and externalizing behavior in a given year predicted high levels of physical discipline in the next year. In Study 2, which followed an independent sample of 290 lower income, higher risk boys from age 10 to 15, mother-reported physical discipline in a given year predicted child ratings of antisocial behavior in the next year, but child antisocial behavior in a given year did not predict parents' use of physical discipline in the next year. In neither sample was there evidence that associations between physical discipline and child externalizing changed as the child aged, and findings were not moderated by gender, race, socioeconomic status, or the severity of the physical discipline. Implications for the reciprocal nature of the socialization process and the risks associated with physical discipline are discussed.

fatigue and depressive symptoms are common among women in the postpartum period, and it has been proposed that fatigue is a risk factor for later depression. To progress this research, there is a need to clarify the conceptual and measurement issue of whether these two sets of symptoms are distinct constructs. There is also a need to determine whether they are distinct constructs beyond the postnatal period. The aim of the study was to assess the construct and discriminant validity of fatigue and depressive symptoms as measured by the SF-36 Vitality subscale (SF-36) and the Edinburgh Postnatal Depression Scale (EPDS) at six months and at four years post partum. data from over 1000 women participating in the Maternal Health Study, a longitudinal study of women׳s physical and psychological health and recovery after childbirth were used. confirmatory factor analysis revealed a two-factor model of fatigue and depressive symptoms represented as distinct but related constructs was a better fit to the data than a one-factor model of fatigue and depression sharing the same underlying construct at both six months and four years post partum. this study provides empirical evidence that maternal fatigue and depression in the first year after having a baby and at four years post partum are best understood as separate psychological constructs or experiences. The findings have important implications for clinical practice, in particular underlining the importance of differentiating tiredness from depression. Copyright © 2014 Elsevier Ltd.

Aims Few studies have evaluated the effect of weight change from pre-pregnancy to post partum with the risk of cardiometabolic diseases among women with a history of gestational diabetes mellitus. The aim of this study was to evaluate the association between weight change from pre-pregnancy to 1–5 years post partum with metabolic syndrome among Chinese women with prior gestational diabetes mellitus. Methods We performed a retrospective cohort study in 1263 women with gestational diabetes mellitus at 1–5 years post partum. Participants were divided into four groups based on their weight change from pre-pregnancy to 1–5 years post partum: loss of ≥ 3 kg, ± 3 kg, gain of 3–7 kg and gain of ≥7 kg. Results The prevalence of metabolic syndrome was 12.1%, 16.2%, 26.0% and 44.3% among women with weight loss ≥ 3 kg, stable weight (± 3 kg), weight gain 3–7 kg and weight gain ≥ 7 kg from pre-pregnancy to post partum, respectively. The positive association between weight change and metabolic syndrome was observed among women with pre-pregnancy normal weight (BMI < 24 kg/m2), overweight (BMI 24–27.9 kg/m2) and obesity (BMI ≥ 28 kg/m2). The prevalence of metabolic syndrome was almost similar among pre-pregnancy normal weight women with weight gain ≥ 7 kg, pre-pregnancy overweight women with stable weight (± 3 kg) and pre-pregnancy obese women with weight loss ≥3 kg from pre-pregnancy to post partum (P = 0.62). Conclusions Women with gestational diabetes mellitus who had large weight gain from pre-pregnancy to post partum were more likely to develop metabolic syndrome. Women who are pre-pregnancy overweight/obesity and also diagnosed as gestational diabetes mellitus during pregnancy need more weight control after delivery. PMID:25962467

Objectives. To evaluate the clinical efficacy of high-intensity focused ultrasound ablation (HIFU) for local recurrence of prostate cancer after external beam radiotherapy (EBRT) and radical prostatectomy (RPE). Materials and Methods: During 2007-2013 years 47 patients with local recurrence of prostate cancer after EBRT and RPE undertook HIFU therapy on the system "Ablaterm» (EDAP, France). Relapse arose after an average of 2 years after EBRT and RPE. Median follow-up after HIFU therapy was 38 (12-60) months. The mean age was 68.5 ± 5.8 years. The median PSA level before HIFU - 15.4 (7-48) ng / mL. Results: In 34 patients (72.3%) at six months after treatment the median PSA was 0.4 (0-3.2) ng / mL, in 48 months - 0.9 (0.4-7.5) ng / mL. In 13 patients (27.7%) at 6 months was observed progression of the disease. In general, after a 5-year follow-up 72.3% of the patients had no data for the progression and recurrence. Conclusion: HIFU therapy in patients with local recurrence of prostate cancer after EBRT and RPE is minimally invasive and effective technology.

Anthrax is one of the zoonotic diseases that usually affects animals and can be transmitted to humans. Immune response of the body during an infection is the presence of antibodies as an effort to defend the body and it will survive for some time in the blood. The aim study is to find out how the initial response to the formation of antibodies and how these antibodies survive after one year. This study is cohort to people exposed to anthrax and found 130 people exposed to anthrax. The most risk factor was direct contact and consumed infected animal meat, which was 34.6%. Clinical manifestations of the skin were 12.3% and all respondents showed positive IgG. While 87.7% did not show any anthrax symptoms. IgG serum examination after 1 year of exposure to anthrax obtained 3.8% still detected antibodies in the body. The relationship between IgG titers with clinical manifestations of anthrax at one year post-outbreak is highly significant p 0.028. In conclusion a significant association between the clinical manifestation with antibody serum anthrax and it still detected after one-year post outbreaks of anthrax.

Distal tibial pilon fractures include extra-articular fractures of the tibial metaphysis and the more severe intra-articular tibial pilon fractures. There is no universal method for treating distal tibial pilon fractures. These fractures are treated by means of open reduction, internal fixation (ORIF) and external skeletal fixation. The high rate of soft-tissue complications associated with primary ORIF of pilon fractures led to the use of external skeletal fixation, with limited internal fixation as an alternative technique for definitive management. The aim of this study was to estimate efficacy of distal tibial pilon fratures treatment using the external skeletal and minimal internal fixation method. We presented a series of 31 operated patients with tibial pilon fractures. The patients were operated on using the method of external skeletal fixation with a minimal internal fixation. According to the AO/OTA classification, 17 patients had type B fracture and 14 patients type C fractures. The rigid external skeletal fixation was transformed into a dynamic external skeletal fixation 6 weeks post-surgery. This retrospective study involved 31 patients with tibial pilon fractures, average age 41.81 (from 21 to 60) years. The average follow-up was 21.86 (from 12 to 48) months. The percentage of union was 90.32%, nonunion 3.22% and malunion 6.45%. The mean to fracture union was 14 (range 12-20) weeks. There were 4 (12.19%) infections around the pins of the external skeletal fixator and one (3.22%) deep infections. The ankle joint arthrosis as a late complication appeared in 4 (12.90%) patients. All arthroses appeared in patients who had type C fractures. The final functional results based on the AOFAS score were excellent in 51.61%, good in 32.25%, average in 12.90% and bad in 3.22% of the patients. External skeletal fixation and minimal internal fixation of distal tibial pilon fractures is a good method for treating all types of inta-articular pilon fractures. In

To assess the long-term (20 years) effectiveness of the UroLume wallstent(TM) (Pfizer Inc., UK) in the treatment of detrusor external sphincter dyssynergia (DESD) in patients with spinal cord injury (SCI). Twelve patients with quadriplegia secondary to SCI underwent external striated sphincter stenting with the UroLume wallstent in place of sphincterotomy for DESD ≈ 20 years ago. The mean (range) age was 41.8 (26-65) years. Eleven patients had cervical level injury whilst one had a thoracic injury. All the patients were shown to have high-pressure neurogenic detrusor overactivity and DESD with incomplete emptying on preoperative video-cystometrograms (VCMG). Six of the 12 patients have now been followed-up for a mean (range) of 20 (19-21) years. Of the remaining six, two were lost to follow-up at 1 and 3 years, but both remained free of complications during that time. Two patients developed encrustation causing obstruction, requiring stent removal within 1 year of insertion. Another patient with an adequately functioning stent died 7 years after stent insertion from a chest infection. The twelfth patient developed bladder cancer 14 years after stent insertion and underwent cystectomy with urinary diversion. VCMG follow-up of the six patients showed a significantly sustained reduction of maximum detrusor pressure and duration of detrusor contraction at the 20-year follow-up. Five of these six patients developed bladder neck dyssynergia of varying degrees as shown on VCMG within the first 9 years of follow-up. All were successfully treated with bladder neck incision (BNI) where the last BNI needed was at 12 years. We did not encounter any problem with stent migration, urethral erosion, erectile dysfunction or autonomic dysreflexia. Urethral stenting using the UroLume wallstent is effective in the management of DESD in patients with SCI and provides an acceptable long-term (20-year follow-up) alternative to sphincterotomy. The failures manifest within the first few

Purpose: To evaluate the response to therapy for anal carcinoma using post-therapy imaging with positron emission tomography (PET)/computed tomography and F-18 fluorodeoxyglucose (FDG) and to compare the metabolic response with patient outcome. Patients and Methods: This was a prospective cohort study of 53 consecutive patients with anal cancer. All patients underwent pre- and post-treatment whole-body FDG-PET/computed tomography. Patients had been treated with external beam radiotherapy and concurrent chemotherapy. Whole-body FDG-PET was performed 0.9-5.4 months (mean, 2.1) after therapy completion. Results: The post-therapy PET scan did not show any abnormal FDG uptake (complete metabolic response) in 44 patients. Persistent abnormal FDGmore » uptake (partial metabolic response) was found in the anal tumor in 9 patients. The 2-year cause-specific survival rate was 94% for patients with a complete vs. 39% for patients with a partial metabolic response in the anal tumor (p = 0.0008). The 2-year progression-free survival rate was 95% for patients with a complete vs. 22% for patients with a partial metabolic response in the anal tumor (p < 0.0001). A Cox proportional hazards model of survival outcome indicated that a complete metabolic response was the most significant predictor of progression-free survival in our patient population (p = 0.0003). Conclusions: A partial metabolic response in the anal tumor as determined by post-therapy FDG-PET is predictive of significantly decreased progression-free and cause-specific survival after chemoradiotherapy for anal cancer.« less

During early conceptual design of complex systems, speed and accuracy are often at odds with one another. While many characteristics of the design are fluctuating rapidly during this phase there is nonetheless a need to acquire accurate data from which to down-select designs as these decisions will have a large impact upon program life-cycle cost. Therefore enabling the conceptual designer to produce accurate data in a timely manner is tantamount to program viability. For conceptual design of launch vehicles, trajectory analysis and optimization is a large hurdle. Tools such as the industry standard Program to Optimize Simulated Trajectories (POST) have traditionally required an expert in the loop for setting up inputs, running the program, and analyzing the output. The solution space for trajectory analysis is in general non-linear and multi-modal requiring an experienced analyst to weed out sub-optimal designs in pursuit of the global optimum. While an experienced analyst presented with a vehicle similar to one which they have already worked on can likely produce optimal performance figures in a timely manner, as soon as the "experienced" or "similar" adjectives are invalid the process can become lengthy. In addition, an experienced analyst working on a similar vehicle may go into the analysis with preconceived ideas about what the vehicle's trajectory should look like which can result in sub-optimal performance being recorded. Thus, in any case but the ideal either time or accuracy can be sacrificed. In the authors' previous work a tool called multiPOST was created which captures the heuristics of a human analyst over the process of executing trajectory analysis with POST. However without the instincts of a human in the loop, this method relied upon Monte Carlo simulation to find successful trajectories. Overall the method has mixed results, and in the context of optimizing multiple vehicles it is inefficient in comparison to the method presented POST's internal

Rarely have researchers elucidated early childhood precursors of externalizing behaviors for boys and girls from a normative sample. Toddlers (N = 104; 52 girls) were observed interacting with a same-sex peer and their mothers, and indices of conflict-aggression, emotion and behavior dysregulation, parenting, and child externalizing problems were obtained. Results indicated that boys initiated more conflictual-aggressive interactions as toddlers and had more externalizing difficulties 2 years later, yet girls' (not boys') conflict-aggressive initiations at age 2 were related to subsequent externalizing problems. When such initiations were controlled for, emotional-behavioral undercontrol at age 2 also independently predicted externalizing problems at age 4. Moreover, the relation between conflict-aggressive initiations at age 2 and externalizing problems at age 4 was strongest for dysregulated toddlers. Finally, the relation between age 2 conflict-aggressive initiations and age 4 externalizing problems was strongest for those toddlers who incurred high levels of maternal negativity. These findings illustrate temperament by parenting connections in the development of externalizing problems.

In developing countries, due to limited availability of modern anesthesia and overcrowding of the hospitals with patients who need surgery, high-risk patients with “intertrochanteric” fractures remain unsuita ble for open reduction and internal fixation. The aim of this study was to analyze the results of external fixation of “intertrochanteric” fractures in high-risk geriatric patients in a developing country. The results of 62 ambulatory high-risk geriatric patients with a mean age of 70 years (range 58–90 years) with “intertrochanteric” fractures, in whom external fixation was performed, are reported. Eight patients died during follow-up due to medical causes unrelated to the surgical procedure. So only 54 patients were available for final assessment. Procedure is simple, performed under local anesthesia, requires less time for surgery and is associated with less blood loss. Good fixation and early ambulation was achieved in most of the patients. Average time to union was 14 weeks. Thirty-one patients developed superficial pin tract infection and 28 patients had average shortening of 15 mm due to impaction and varus angulation. Functional outcome was assessed using Judet's point system. Good to excellent results were achieved in 44 patients. This study demonstrated that external fixation of “intertrochantric” fractures performed under local anesthesia offers significant advantage in ambulatory high-risk geriatric patients especially in a developing country.

We present the results of a three-year operational-aging test of a specially designed prototype flight laser operating at 1064 nm, 10 kHz, 1ns, 15W average power and externally frequency-doubled. Fibertek designed and built the q-switched, 1064nm laser and this laser was in a sealed container of dry air pressurized to 1.3 atm. The external frequency doubler was in a clean room at a normal air pressure. The goal of the experiment was to measure degradation modes at 1064 and 532 nm separately. The external frequency doubler consisted of a Lithium triborate, LiB3O5, non-critically phase-matched crystal. After some 1064 nm light was diverted for diagnostics, 13.7W of fundamental power was available to pump the doubling crystal. Between 8.5W and 10W of 532nm power was generated, depending on the level of stress and degradation. The test consisted of two stages, the first at 0.3 J/cm2 for almost 1 year, corresponding to expected operational conditions, and the second at 0.93 J/cm2 for the remainder of the experiment, corresponding to accelerated optical stress testing. We observed no degradation at the first stress-level and linear degradation at the second stress-level. The linear degradation was linked to doubler crystal output surface changes from laser-assisted contamination. We estimate the expected lifetime for the flight laser at 532 nm using fluence as the stress parameter. This work was done for NASA's Ice, Cloud, and land Elevation Satellite-2 (ICESat-2) LIDAR at Goddard Space Flight Center in Greenbelt, MD with the goal of 1 trillion shots lifetime.

Case mix adjustment is required to allow valid comparison of outcomes across care providers. However, there is a lack of externally validated models suitable for use in unselected stroke admissions. We therefore aimed to develop and externally validate prediction models to enable comparison of 30-day post-stroke mortality outcomes using routine clinical data. Models were derived (n=9000 patients) and internally validated (n=18 169 patients) using data from the Sentinel Stroke National Audit Program, the national register of acute stroke in England and Wales. External validation (n=1470 patients) was performed in the South London Stroke Register, a population-based longitudinal study. Models were fitted using general estimating equations. Discrimination and calibration were assessed using receiver operating characteristic curve analysis and correlation plots. Two final models were derived. Model A included age (<60, 60-69, 70-79, 80-89, and ≥90 years), National Institutes of Health Stroke Severity Score (NIHSS) on admission, presence of atrial fibrillation on admission, and stroke type (ischemic versus primary intracerebral hemorrhage). Model B was similar but included only the consciousness component of the NIHSS in place of the full NIHSS. Both models showed excellent discrimination and calibration in internal and external validation. The c-statistics in external validation were 0.87 (95% confidence interval, 0.84-0.89) and 0.86 (95% confidence interval, 0.83-0.89) for models A and B, respectively. We have derived and externally validated 2 models to predict mortality in unselected patients with acute stroke using commonly collected clinical variables. In settings where the ability to record the full NIHSS on admission is limited, the level of consciousness component of the NIHSS provides a good approximation of the full NIHSS for mortality prediction. © 2014 American Heart Association, Inc.

Object To investigate white matter structural abnormalities using diffusion tensor imaging (DTI) in children with hydrocephalus before CSF diversionary surgery (including ventriculoperitoneal shunting and endoscopic third ventriculoscopy) and the course of recovery post-surgery in association with neuropsychological and behavioral outcome. Methods This was a prospective study that included 54 children with congenital hydrocephalus (21F/33M; age range: 0.03–194.5 months) who underwent surgery and 64 normal controls (30F/34M, age range: 0.30–197.75 months). DTI and neurodevelopmental outcome data were collected once in the control group and at pre-surgery, 3-month, and 12-month post-surgery in the patients. DTI measures, including fractional anisotropy (FA), mean diffusivity (MD), axial diffusivity (AD), and radial diffusivity (RD) values were extracted from the genu of corpus callosum (gCC) and the posterior limb of internal capsule (PLIC). Group analysis was performed first cross-sectionally to quantify DTI abnormalities at three time points by comparing the controls and the patients group at the three time points separately. Longitudinal comparisons were conducted pairwise between different time points in patients whose data were acquired at multiple time points. Neurodevelopmental data were collected and analyzed using the Adaptive Behavior Assessment System, Second Edition (ABAS-II) and the Bayley Scales of Infant Development, Third Edition (Bayley-III). Correlation analyses were performed between DTI and behavioral outcomes. Results Significant DTI abnormalities were found in both the gCC (lower FA and higher MD, AD, and RD) and the PLIC (higher FA, lower AD and RD) at pre-surgery. The DTI measures in the gCC remained mostly abnormal at 3-month and 12-month post-surgery. The DTI abnormalities in the PLIC were significant in FA and AD at 3-month post-surgery but did nor persist when tested at 12-month post-surgery. Significant longitudinal DTI changes in the

Family income, parental education and internalizing and externalizing psychopathology among 2-3-year-old Chinese children: the mediator effect of parent-child conflict.

2014-02-01

Using a sample of 156 Chinese children aged 2-3 years and their parents, this study examined the effects of socio-economic status, specifically family income and parental education, on the children's internalizing and externalizing psychopathology and whether these effects were mediated by mother-child and father-child conflict. Results indicated that family income, maternal education and paternal education all negatively predicted externalizing symptoms. Income also negatively predicted internalizing symptoms among boys but not girls. Maternal education negatively predicted internalizing symptoms among girls but not boys. The effects of income on psychopathology were fully mediated by mother-child and father-child conflict. In contrast, the effects of education were not mediated or only partially mediated by conflict. Findings are discussed in the framework of the family stress model. © 2013 International Union of Psychological Science.

One-Year Review of the SCREEN (Skin Cancer Post-Transplant) Clinic.

PubMed

Baldwin, Sarah; Au, Sheila

The Skin Cancer Post-Transplant (SCREEN) Clinic is a skin-cancer screening clinic that is fully integrated into the renal transplantation clinic at St Paul's Hospital in Vancouver, British Columbia. The purpose of this review was to determine characteristics of patients most at risk for skin cancer, to specify types and locations of skin cancers diagnosed, and to identify areas for patient and physician education. Transplant patients (91% renal; 5% heart) screened by a dermatologist during a 12-month period were stratified into low-, medium-, and high-risk groups based on detailed history and skin examination. In total, 118 skin cancers were diagnosed. White males were found to be most at risk. Squamous cell carcinoma accounted for the majority of tumours, over 25% of which demonstrated invasion. Forty-two percent of patients used only 1 to 2 bottles of sunscreen per year, and sun-protective practices were limited. With this information, we have identified potential target areas for patient and physician education.

2015-08-01

To describe illness cognitions two months and two years post stroke and to investigate changes in illness cognitions over time. We also examined the associations between illness cognitions and life satisfaction at two months and two years post stroke and investigated if changes in illness cognitions predicted life satisfaction two years post stroke, taking demographic and stroke-related factors and emotional symptoms into account. Prospective cohort study in which 287 patients were assessed at two months and two years post stroke. The illness cognitions helplessness (maladaptive), acceptance (adaptive) and perceiving benefits (adaptive) were measured with the Illness Cognition Questionnaire. Life satisfaction was assessed with two life satisfaction questions. Correlational and regression analyses were performed. Patients experienced both maladaptive and adaptive illness cognitions two months and two years post stroke. Only acceptance increased significantly from two months to two years post stroke (p≤0.01). Helplessness, acceptance and perceiving benefits were significantly associated with life satisfaction at two months (R2=0.42) and two years (R2=0.57) post stroke. Furthermore, illness cognitions two months post stroke and changes in illness cognitions predicted life satisfaction two years post stroke (R2=0.57). Illness cognitions and changes in illness cognitions were independently associated with life satisfaction two years post stroke. It is therefore important during rehabilitation to focus on reducing maladaptive behavior and feelings to promote life satisfaction, and on promoting adaptive illness cognitions.

Shenesey, Jessica W; Langhinrichsen-Rohling, Jennifer

2015-05-01

Scant research has focused on resilient responding to disasters such as oil spills a year or more after the event. One year after the BP Deepwater Horizon oil spill, this study assessed perceived resilience, relations between resiliency and psychological symptoms, and the degree to which self-reported resiliency was associated with reduced psychological symptoms after accounting for differences in economic impact sustained by Gulf Coast residents. Participants were 812 adults (64% women, mean age 50) of 2 Alabama coastal communities. Participants were administered a telephone survey 1-year post-spill assessing self-perceptions of impact factors (e.g., economic and social), resilience, coping, and depressive and PTSD symptoms. Most participants perceived themselves as resilient (n = 739). As expected, lower perceived resilience was associated with greater ongoing depressive and PTSD symptoms. Spill-related economic impact predicted greater depressive and PTSD symptoms; however, perceived resilience predicted significant variance in psychological symptoms after taking into account spill-related economic impact. Improving individuals' sense of resiliency may help mitigate psychosocial and mental health effects over time. (c) 2015 APA, all rights reserved).

Burlaka, Viktor

2016-01-01

The purpose of this study was to assess the association of positive and negative parenting with child externalizing problems. Quantitative data were collected during face-to-face interviews with 320 parents of children 9–16 years of age (50% males) in 11 communities in Eastern, Southern and Central Ukraine. The study estimated the relationship between parenting practices and child externalizing behaviors, such as aggression, delinquency and attention problems. Results revealed that positive parenting, child monitoring, and avoidance of corporal punishment were associated with fewer child externalizing symptoms. Results also indicated that child male gender and single parenting had significant and positive association with child externalizing behaviors. This study extends international psychosocial knowledge on children and families. These findings can be used to design programs and foster dialogues about the role of family and social environments in the development of externalizing disorder among researchers, representatives of governmental and non-governmental organizations and mass media that work with child abuse prevention in Ukraine.

Using data from two long-term longitudinal projects, we investigated reciprocal relations between maternal reports of physical discipline and teacher and self ratings of child externalizing behavior, accounting for continuity in both discipline and externalizing over time. In Study 1, which followed a community sample of 562 boys and girls from age 6–9, high levels of physical discipline in a given year predicted high levels of externalizing behavior in the next year, and externalizing behavior in a given year predicted high levels of physical discipline in the next year. In Study 2, which followed an independent sample of 290 lower income, higher risk boys from age 10–15, mother-reported physical discipline in a given year predicted child ratings of antisocial behavior in the next year, but child antisocial behavior in a given year did not predict parents’ use of physical discipline in the next year. In neither sample was there evidence that associations between physical discipline and child externalizing changed as the child aged, and findings were not moderated by gender, race, socioeconomic status, or the severity of the physical discipline. Implications for the reciprocal nature of the socialization process and the risks associated with physical discipline are discussed. PMID:21262050

While the effects of growth from birth to expected term on the subsequent development of preterm children has attracted plentiful attention, less is known about the effects of post-term growth. We aimed to delineate distinct patterns of post-term growth and to determine their association with the cognitive development of preterm children. Data from a prospective population-based cohort of 3,850 surviving infants born at less than 35 weeks of gestational age were used. Growth was assessed as the Body Mass Index (BMI) Z-scores at 3, 9, 18, 24, 36, 48, and 60 months. Cognitive development at five years of age was evaluated by the Global School Adaptation score (GSA). Latent class analysis was implemented to identify distinct growth patterns and logistic regressions based on propensity matching were used to evaluate the relationship between identified growth trajectories and cognitive development. Four patterns of post-term growth were identified: a normal group with a Z-score consistently around zero during childhood (n = 2,469; 64%); a group with an early rapid rise in the BMI Z-score, but only up to 2 years of age (n = 195; 5%); a group with a slow yet steady rise in the BMI Z-score during childhood (n = 510; 13%); and a group with a negative Z-score growth until 3 years of age (n = 676; 18%). The group with a slow yet steady rise in the BMI Z-score was significantly associated with low GSA scores. Our findings indicate heterogeneous post-term growth of preterm children, with potential for association with their cognitive development.

Forty-three patients, all male, with limited epidermoid carcinoma of the soft palate and uvula were treated by interstitial implant usually associated with external radiotherapy. Most patients received 50 Gy external irradiation to the oropharynx and neck followed by 20-35 Gy by interstitial iridium-192 wires using either guide gutters or a plastic tube technique. Twelve primary tumors and two recurrences after external irradiation alone had implant only for 65-75 Gy. Total actuarial local control is 92% with no local failures in 34 T1 primary tumors. Only one serious complication was seen. Overall actuarial survival was 60% at 3 years and 37%more » at 5 years but cause-specific survivals were 81% and 64%. The leading cause of death was other aerodigestive cancer, with an actuarial rate of occurrence of 10% per year after treatment of a soft palate cancer. Interstitital brachytherapy alone or combined with external irradiation is safe, effective management for early carcinoma of the soft palate and uvula but second malignancy is a serious problem.« less

External forcing as a metronome for Atlantic multidecadal variability

NASA Astrophysics Data System (ADS)

Otterå, Odd Helge; Bentsen, Mats; Drange, Helge; Suo, Lingling

2010-10-01

Instrumental records, proxy data and climate modelling show that multidecadal variability is a dominant feature of North Atlantic sea-surface temperature variations, with potential impacts on regional climate. To understand the observed variability and to gauge any potential for climate predictions it is essential to identify the physical mechanisms that lead to this variability, and to explore the spatial and temporal characteristics of multidecadal variability modes. Here we use a coupled ocean-atmosphere general circulation model to show that the phasing of the multidecadal fluctuations in the North Atlantic during the past 600 years is, to a large degree, governed by changes in the external solar and volcanic forcings. We find that volcanoes play a particularly important part in the phasing of the multidecadal variability through their direct influence on tropical sea-surface temperatures, on the leading mode of northern-hemisphere atmosphere circulation and on the Atlantic thermohaline circulation. We suggest that the implications of our findings for decadal climate prediction are twofold: because volcanic eruptions cannot be predicted a decade in advance, longer-term climate predictability may prove challenging, whereas the systematic post-eruption changes in ocean and atmosphere may hold promise for shorter-term climate prediction.

To assess the occurrence of secondary health conditions and their potential risk factors in persons with spinal cord injury from 1 to 5 years after discharge from initial inpatient rehabilitation. Multicentre longitudinal study. A total of 139 wheelchair-dependent persons with spinal cord injury. The occurrence of secondary health conditions and their potential risk factors were assessed in a clinical interview with a rehabilitation physician at 1 and 5 years after discharge from inpatient rehabilitation and by a telephone interview 2 years after discharge. Self-report questionnaires were used for the assessment of musculoskeletal and neuropathic pain. Neuropathic pain (83.7-92.1%), musculoskeletal pain (62.3-87.1%) and urinary tract infection (56.5-58.9%) were the most frequently reported secondary health conditions. The occurrence of several secondary health conditions was higher among women and individuals with a complete lesion, tetraplegia, and with a higher body mass index. Secondary health conditions are common in the first years post-discharge following spinal cord injury, and their course seems to be relatively stable. These results emphasize the number of health issues that must be considered during post-injury care of persons with spinal cord injury living in the community, and the importance of a well-coordinated interdisciplinary approach from specialized rehabilitation centres.

Institutional care and iron deficiency increase ADHD symptomology and lower IQ 2.5-5 years post-adoption.

Doom, Jenalee R; Georgieff, Michael K; Gunnar, Megan R

2015-05-01

Increased ADHD symptomology and lower IQ have been reported in internationally adopted (IA) children compared to non-adopted peers (Hostinar, Stellern, Schaefer, Carlson & Gunnar, 2012; Kreppner, O'Connor & Rutter, 2001). However, it is unclear whether these outcomes are due to institutional deprivation specifically or to co-occurring micronutrient deficiencies that disrupt brain development (Fuglestad, Rao & Georgieff, 2008b). In this study, IA children were compared to children raised in their biological families to examine differences in ADHD symptomology and IQ 2.5-5 years post-adoption and to assess the contributions of iron deficiency (ID) and duration of deprivation to these cognitive outcomes. ADHD symptoms (parent- and experimenter-reported) and IQ were evaluated in 88 IA (M = 62.1 months, SD = 2.4) and 35 non-adopted children (M = 61.4 months, SD = 1.6). IA children were assessed 29-64 months post-adoption (M = 41.9 months, SD = 10.2). ID was assessed during the initial post-adoption medical visit in 69 children, and children were classified into four groups by iron status, ranging from normal to ID anemia (most severe). IA children had greater ADHD symptomology, p < .01, and lower IQ, p = .001, than non-adopted children. Within the IA group, children with more severe ID at adoption had greater ADHD symptomology, r(69) = 0.40, p = .001, and lower IQ, r(68) = -0.28, p < .05. Duration of institutional care was positively correlated with ADHD symptoms, r(86) = .28, p < .01, but not IQ, r(85) = -.08, p = .52. Longitudinal results indicate improvement in IQ from 12 months post-adoption to age 5 for children with greater ID severity at adoption and longer duration of institutional care but no improvement in ADHD symptoms. These results signify continuing effects of early deprivation and ID on ADHD symptoms and IQ years after adoption.

2011-01-01

The External Tank forms the structural backbone of the Space Shuttle in the launch configuration. Because the tank flies to orbital velocity with the Space Shuttle Orbiter, minimization of weight is mandatory, to maximize payload performance. Choice of lightweight materials both for structure and thermal conditioning was necessary. The tank is large, and unique manufacturing facilities, tooling, handling, and transportation operations were required. Weld processes and tooling evolved with the design as it matured through several block changes, to reduce weight. Non Destructive Evaluation methods were used to assure integrity of welds and thermal protection system materials. The aluminum-lithium alloy was used near the end of the program and weld processes and weld repair techniques had to be refined. Development and implementation of friction stir welding was a substantial technology development incorporated during the Program. Automated thermal protection system application processes were developed for the majority of the tank surface. Material obsolescence was an issue throughout the 40 year program. The final configuration and tank weight enabled international space station assembly in a high inclination orbit allowing international cooperation with the Russian Federal Space Agency. Numerous process controls were implemented to assure product quality, and innovative proof testing was accomplished prior to delivery. Process controls were implemented to assure cleanliness in the production environment, to control contaminants, and to preclude corrosion. Each tank was accepted via rigorous inspections, including non-destructive evaluation techniques, proof testing, and all systems testing. In the post STS-107 era, the project focused on ascent debris risk reduction. This was accomplished via stringent process controls, post flight assessment using substantially improved imagery, and selective redesigns. These efforts were supported with a number of test programs to

Mothers living with HIV (MLH) and their children are typically studied to ensure that perinatal HIV transmission is blocked. Yet, HIV impacts MLH and their children lifelong. We examine child outcomes from pregnancy to 3 years post-birth among a peri-urban population of pregnant MLH and mothers without HIV (MWOH). Almost all pregnant women in 12 neighborhoods (98 %; N = 584) in Cape Town, South Africa were recruited and repeatedly assessed within 2 weeks of birth (92 %), at 6 months (88 %), 18 months (84 %), and 3 years post-birth (86 %). There were 186 MLH and 398 MWOH. Controlling for neighborhood and repeated measures, child and maternal outcomes were contrasted over time using longitudinal random effects regression analyses. For measures collected only at 3 years, outcomes were analyzed using multiple regressions. Compared to MWOH, MLH had less income, more informal housing and food insecurity, used alcohol more often during pregnancy, and were more depressed during pregnancy and over time. Only 4.8 % of MLH's children were seropositive; seropositive children were excluded from additional analyses. Children of MLH tended to have significantly lower weights (p < .10) over time (i.e., lower weight-for-age Z-scores) and were also hospitalized significantly more often than children of MWOH (p < .01). Children of MLH and MWOH died at similar rates (8.5 %) and were similar in social and behavioral adjustment, vocabulary, and executive functioning at 3 years post-birth. Despite living in households with fewer resources and having more depressed mothers, only the physical health of children of MLH is compromised, compared to children of MWOH. In township neighborhoods with extreme poverty, social, behavioral, language, and cognitive functioning appear similar over the first three years of life between children of MLH and MWOH.

External genitalia are found in each of the major clades of amniotes. The phallus is an intromittent organ that functions to deliver sperm into the female reproductive tract for internal fertilization. The cellular and molecular genetic mechanisms of external genital development have begun to be elucidated from studies of the mouse genital tubercle, an embryonic appendage adjacent to the cloaca that is the precursor of the penis and clitoris. Progress in this area has improved our understanding of genitourinary malformations, which are among the most common birth defects in humans, and created new opportunities for comparative studies of other taxa. External genitalia evolve rapidly, which has led to a striking diversity of anatomical forms. Within the past year, studies of external genital development in non-mammalian amniotes, including birds, lizards, snakes, alligators, and turtles, have begun to shed light on the molecular and morphogenetic mechanisms underlying the diversification of phallus morphology. Here, we review recent progress in the comparative developmental biology of external genitalia and discuss the implications of this work for understanding external genital evolution. We address the question of the deep homology (shared common ancestry) of genital structures and of developmental mechanisms, and identify new areas of investigation that can be pursued by taking a comparative approach to studying development of the external genitalia. We propose an evolutionary interpretation of hypospadias, a congenital malformation of the urethra, and discuss how investigations of non-mammalian species can provide novel perspectives on human pathologies.

Severe acute respiratory syndrome (SARS) is a highly contagious infectious disease which first emerged in late 2002, caused by a then novel human coronavirus, SARS coronavirus (SARS-CoV). The virus is believed to have originated from bats and transmitted to human through intermediate animals such as civet cats. The re-emergence of SARS-CoV remains a valid concern due to the continual persistence of zoonotic SARS-CoVs and SARS-like CoVs (SL-CoVs) in bat reservoirs. In this study, the screening for the presence of SARS-specific T cells in a cohort of three SARS-recovered individuals at 9 and 11 years post-infection was carried out, and all memory T cell responses detected target the SARS-CoV structural proteins. Two CD8(+) T cell responses targeting the SARS-CoV membrane (M) and nucleocapsid (N) proteins were characterized by determining their HLA restriction and minimal T cell epitope regions. Furthermore, these responses were found to persist up to 11 years post-infection. An absence of cross-reactivity of these CD8(+) T cell responses against the newly-emerged Middle East respiratory syndrome coronavirus (MERS-CoV) was also demonstrated. The knowledge of the persistence of SARS-specific celullar immunity targeting the viral structural proteins in SARS-recovered individuals is important in the design and development of SARS vaccines, which are currently unavailable.

The present study examined the role of positive parenting on externalizing behaviors in a longitudinal, genetically informative sample. It often is assumed that positive parenting prevents behavior problems in children via an environmentally mediated process. Alternatively, the association may be due to either an evocative gene-environment correlation, in which parents react to children's genetically-influenced behavior in a positive way, or a passive gene-environment correlation, where parents passively transmit a risk environment and the genetic risk factor for the behavioral outcome to their children. The present study estimated the contribution of these processes in the association between positive parenting and children's externalizing behavior. Positive parenting was assessed via observations at ages 7, 9, 14, 24, and 36 months and externalizing behaviors were assessed through parent report at ages 4, 5, 7, 9, 10, 11, and 12 years. The significant association between positive parenting and externalizing behavior was negative, with children of mothers who showed significantly more positive parenting during toddlerhood having lower levels of externalizing behavior in childhood; however, there was not adequate power to distinguish whether this covariation was due to genetic, shared environmental, or nonshared environmental influences.

This study measured root surface temperature changes when ultrasonic vibration, with and without irrigation, was applied to cemented endodontic posts. Twenty-six, extracted, single-rooted premolars were randomly divided into two groups. Root lengths were standardized, canals instrumented, obturated, and posts cemented into prepared spaces. Thermocouples were positioned at two locations on the proximal root surfaces. Samples were embedded in plaster and brought to 37 degrees C in a water bath. Posts were ultrasonically vibrated for 4 minutes while continuously measuring temperature. Two-way ANOVA compared effects of water coolant and thermocouple location on temperature change. Root surface temperatures were significantly higher (p < 0.001) when posts were instrumented dry. A trend for higher temperatures was observed at coronal thermocouples of nonirrigated teeth and at apical thermocouples of irrigated teeth (p = 0.057). Irrigation during post removal with ultrasonics had a significant impact on the temperature measured at the external root surface.

Mechanical loading is believed to be a critical factor in the development and treatment of knee osteoarthritis. However, the contact forces to which the knee articular surfaces are subjected during daily activities cannot be measured clinically. Thus, the ability to predict internal knee contact forces accurately using external measures (i.e., external knee loads and muscle electromyographic [EMG] signals) would be clinically valuable. We quantified how well external knee load and EMG measures predict internal knee contact forces during gait. A single subject with a force-measuring tibial prosthesis and post-operative valgus alignment performed four gait patterns (normal, medial thrust, walking pole, and trunk sway) to induce a wide range of external and internal knee joint loads. Linear regression analyses were performed to assess how much of the variability in internal contact forces was accounted for by variability in the external measures. Though the different gait patterns successfully induced significant changes in the external and internal quantities, changes in external measures were generally weak indicators of changes in total, medial, and lateral contact force. Our results suggest that when total contact force may be changing, caution should be exercised when inferring changes in knee contact forces based on observed changes in external knee load and EMG measures. Advances in musculoskeletal modeling methods may be needed for accurate estimation of in vivo knee contact forces. Copyright © 2012 Orthopaedic Research Society.

Despite various treatments to control intracranial pressure (ICP) after brain injury, patients may present a late onset of high ICP or a poor response to medications. External lumbar drainage (ELD) can be considered a therapeutic option if high ICP is due to communicating external hydrocephalus. We aimed at describing the efficacy and safety of ELD used in a cohort of traumatic or non-traumatic brain-injured patients. In this multicentre retrospective analysis, patients had a delayed onset of high ICP after the initial injury and/or a poor response to ICP treatments. ELD was considered in the presence of radiological signs of communicating external hydrocephalus. Changes in ICP values and side effects following the ELD procedure were reported. Thirty-three patients with a median age of 51 years (25-75th percentile: 34-61 years) were admitted after traumatic (n = 22) or non-traumatic (n = 11) brain injuries. Their initial Glasgow Coma Scale score was 8 (4-11). Eight patients underwent external ventricular drainage prior to ELD. Median time to ELD insertion was 5 days (4-8) after brain insult. In all patients, ELD was dramatically effective in lowering ICP: 25 mmHg (20-31) before versus 7 mmHg (3-10) after (p < 0.001). None of the patients showed adverse effects such as pupil changes or intracranial bleeding after the procedure. One patient developed an ELD-related infection. These findings indicate that ELD may be considered potentially effective in controlling ICP, remaining safe if a firm diagnosis of communicating external hydrocephalus has been made.

To assess grief and post-traumatic growth in parents 2-6 years after the death of a premature baby (24-26 weeks' gestation) and to evaluate Pictorial Representation of Illness and Self-Measure (PRISM) in the assessment of bereavement. Fifty-four parents were assessed for their experiences during hospitalization and by questionnaires regarding grief (MTS), post-traumatic growth, affective symptoms and the visual representation of the baby and the self of the parents (PRISM). Even 2-6 years after the loss of their extremely preterm infant the parents still suffer a lot from their bereavement, mothers more so than fathers (Mann-Whitney U test, U = 230.5, p < 0.05). Having another child reduced the level of grief (U = 119.0, p < 0.05). Mothers showed more post-traumatic growth than fathers (U = 140.5, p < 0.001). For all parents a shorter distance between the baby and the self (PRISM) correlated with greater grief (rho = -0.62, p < 0.001); in multiple regression analysis MTS explained 38% of the SBS-variance. Clinicians should be aware that the death of an extremely premature infant triggers not only a painful long-term process of mourning but also of individual personal growth. Adaptation processes after the death differ depending on gender, with mothers experiencing more intense grief but also more growth than fathers. The modified PRISM test is recommended as a visual, non-verbal and easy-to-use instrument to assess bereavement. Copyright 2007 S. Karger AG, Basel.

Renal transplantation is considered as the treatment of choice for patients with end-stage renal disease. Health-related quality of life (HRQoL) of renal transplant recipients (RTR) is very important to assess, especially during the first year after transplantation. To provide new evidence about the suitability of HRQoL measures in RTR during the first post-transplant year, we explored the internal structure, reliability and external validity of a French specific HRQoL instrument, the Renal Transplant Quality of life Questionnaire Second Version (RTQ V2). The data were issued from the French multicenter cohort of renal transplant patients followed during 4 years (EPIGREN). The HRQoL of RTR was assessed five times (at 1, 3, 6, 9 and 12 months after transplantation) with the RTQ V2, a specific instrument consisting of 32 items describing five dimensions. Socio-demographic information, clinical characteristics and HRQoL (i.e., RTQ V2 and SF-36) were collected. For the five times, psychometric properties of the RTQ V2 were compared to those reported from the reference population assessed in the validation study. Three hundred and thirty-four patients were enrolled. The proportions of well-projected items, item-internal consistency, item-discriminant validity, floor and ceiling effects, Cronbach's alpha coefficients and item goodness-of-fit statistics were satisfactory for each dimension at the five times of the study. The suitability indices of construct validity were higher than 90 % for each time (minimum-maximum: 90.8-97.4 %). The external validity was less satisfactory, with a suitability indices ranged from 46.7 % at M1 to 66.7 % at M12. However, the discrepancies with the reference population (mainly for the gender) appeared logical considering the scientific literature on HRQoL of RTR during the first post-transplant year and may not compromise the external validity. These results support the validity and reliability of the RTQ V2 for evaluating HRQoL in

The University-External Sector vinculation is an increasing phenomenon in Latin America as in the rest of the world. The universities through its investigation processes actively participate in the creation and incorporation of science and technology to produce technological processes, to bring foreign technology into national reality, and also to create and transmit innovation for the productive sector. In those ways these institutions achieve bonds with the external sector which provide them with additional income and allows them to have certain relief for their tight teaching and investigation budgets. Several studies in university organizations have been made to identify the motivations and barriers for de adequate development of the interaction between the university and the external sector. The lack of vinculation between these institutions could be due in part to the lack of knowledge that the external sector has of the possibility to obtain services from the university, and also the lack of knowledge that the university has about the needs of potential users of their services. The goals achieved by public Venezuelan universities, in the last years, in their search of a vinculation with the external sector could grow and consolidate through an adequate strategic management plan that allows a mayor diffusion and promotion of the results of their investigations and services, to reach in a wider and more direct way, and to a greater number of potential clients.

Escalating wildfire in subalpine forests with stand-replacing fire regimes is increasing the extent of early-seral forests throughout the western USA. Post-fire succession generates the fuel for future fires, but little is known about fuel loads and their variability in young post-fire stands. We sampled fuel profiles in 24-year-old post-fire lodgepole pine (Pinus contorta var. latifolia) stands (n = 82) that regenerated from the 1988 Yellowstone Fires to answer three questions. (1) How do canopy and surface fuel loads vary within and among young lodgepole pine stands? (2) How do canopy and surface fuels vary with pre- and post-fire lodgepole pine stand structure and environmental conditions? (3) How have surface fuels changed between eight and 24 years post-fire? Fuel complexes varied tremendously across the landscape despite having regenerated from the same fires. Available canopy fuel loads and canopy bulk density averaged 8.5 Mg/ha (range 0.0-46.6) and 0.24 kg/m 3 (range: 0.0-2.3), respectively, meeting or exceeding levels in mature lodgepole pine forests. Total surface-fuel loads averaged 123 Mg/ha (range: 43-207), and 88% was in the 1,000-h fuel class. Litter, 1-h, and 10-h surface fuel loads were lower than reported for mature lodgepole pine forests, and 1,000-h fuel loads were similar or greater. Among-plot variation was greater in canopy fuels than surface fuels, and within-plot variation was greater than among-plot variation for nearly all fuels. Post-fire lodgepole pine density was the strongest positive predictor of canopy and fine surface fuel loads. Pre-fire successional stage was the best predictor of 100-h and 1,000-h fuel loads in the post-fire stands and strongly influenced the size and proportion of sound logs (greater when late successional stands had burned) and rotten logs (greater when early successional stands had burned). Our data suggest that 76% of the young post-fire lodgepole pine forests have 1,000-h fuel loads that exceed levels

Human immunodeficiency virus type 1 (HIV-1) and hepatitis B (HBV) and C virus (HCV) viral load determinations are among the most relevant markers for the follow up of patients infected with these viruses. External quality control tools are crucial to ensure the accuracy of results obtained by microbiology laboratories. This article summarized the results obtained from the 2013 SEIMC External Quality Control Programme for HIV-1, HCV, and HBV viral loads. In the HIV-1 program, a total of five standards were sent. One standard consisted in seronegative human plasma, while the remaining four contained plasma from three different viremic patients, in the range of 2-5 log10 copies/mL; two of these standards were identical aiming to determine repeatability. A significant proportion of the laboratories (25% on average) obtained values out of the accepted range (mean ± 0.25 log10 copies/mL), depending on the standard and on the method used for quantification. Repeatability was excellent, with up to 98.9% of laboratories reporting results within the limits (D < 0.5 log10 copies/mL). The HBV and HCV program consisted of two standards with different viral load contents. Most of the participants, 82% in the case of HCV and 78% in the HBV, obtained all the results within the accepted range (mean ± 1.96 SD log10 UI/mL). Data from this analysis reinforce the utility of proficiency programmes to ensure the quality of the results obtained by a particular laboratory, as well as the importance of the post-analytical phase on the overall quality. Due to the remarkable interlaboratory variability, it is advisable to use the same method and the same laboratory for patient follow up. Copyright © 2015 Elsevier España, S.L.U. All rights reserved.

Purpose To summarise post-licensure safety surveillance over more than 4 years of routine use of the human papillomavirus-16/18-AS04-adjuvanted vaccine (HPV-16/18 vaccine: Cervarix®, GlaxoSmithKline, Belgium). Methods We describe global post-licensure passive surveillance data based on routine pharmacovigilance from 18 May 2007 until 17 November 2011 and enhanced surveillance implemented during the 2-year national immunisation programme in the UK (school years 2008–2010). Results Spontaneous reports from countries worldwide showed a similar pattern for the most frequently reported adverse events after HPV-16/18 vaccination. No patterns or trends were observed for potential immune-mediated diseases after vaccination. Observed incidences of Bell's palsy and confirmed Guillain–Barré syndrome were within the expected range in the general population. Outcomes of pregnancy in women who were inadvertently exposed to HPV-16/18 vaccine during pregnancy, were in line with published reports for similar populations. Enhanced surveillance of adverse events in the UK triggered a review of cases of anaphylaxis, angioedema and syncope reports, leading to an update to the prescribing information. Conclusion Collaborative partnerships between industry and national regulatory agencies facilitated rapid notification and transfer of safety information, allowing for rapid responses in the event of a safety signal of adverse event of concern. More than 4 years of post-licensure experience may provide confidence to providers and the public about the safety profile of HPV-16/18 vaccine in routine use. The safety profile appears to be consistent with pre-licensure data reporting that HPV-16/18 vaccine has an acceptable benefit–risk profile in adolescent girls and women. PMID:24644078

Family Violence Pathways and Externalizing Behavior in Youth.

Bozzay, Melanie L; Joy, Lendi N; Verona, Edelyn

2017-08-01

While studies suggest that youth who experience violence in the home are more likely to engage in externalizing behaviors (e.g., aggression, substance use, rule breaking), research is needed to understand factors that may explain how family violence is linked to externalizing, and whether there may be gender-specific trajectories to this outcome. The present study used a cross-sectional design and multigroup, path analytic modeling to test the degree to which personality traits (negative emotionality, constraint) in boys and girls (Model 1), as well as status offending primarily in girls (Model 2), may help explain relationships between exposure to familial adversity (witnessing family violence and child abuse) and adolescent externalizing behaviors in a mixed-gender, community sample with both caregiver and youth reports ( N = 237, 57% female, 10-17 years old). Results indicated that personality traits fully explained the relationship between witnessing family violence and externalizing and partially explained the relationship between child abuse and externalizing among youth. Despite theory suggesting a female-specific trajectory involving status offenses, both models were similarly relevant for boys and girls. These findings have implications for understanding processes by which adverse family circumstances may relate to externalizing behavior in youth. Preliminary suggestions are provided for future longitudinal research, policy changes, and clinical techniques that may be essential in preventing the progression to long-term adverse outcomes among youth.

External dacryocystorhinostomy (DCR) is often performed under local anesthesia (LA) without adequate knowledge of the pain experienced by the patient. We subdivided our surgical technique into stages easily understood by the patients (introducing cotton tipped applicators, performing parabulbar injection, creating the incision, bone cracking (opening the ostium), manipulating the nose, intubating, closing the wound, and packing with gauze). A total of 50 patients ranging in age from 31 to 83 years of age (63.64±9.64) underwent external DCR. Each patient was asked 30 minutes after surgery to indicate the intensity of pain experienced at each stage of the surgery and during intramuscular (i.m.) injection of an antibiotic using a visual analog scale (VAS). Analysis of the VAS-based pain scores indicated 3 statistically equal occurrences of pain coinciding with the opening of the ostium, and receiving both parabulbar anesthetic and i.m. antibiotic injections. The level of pain experienced during the most unpleasant stage of external DCR (ostium opening) was similar to the pain experienced from an i.m. injection. Patients can be informed that pain during external DCR with local anesthesia is comparable to receiving an i.m. gluteal injection.

Frequent external-focus feedback enhances motor learning.

The present study examined the hypothesis that feedback inducing an external focus of attention enhances motor learning if it is provided frequently (i.e., 100%) rather than less frequently. Children (10- to 12-year-olds) practiced a soccer throw-in task and were provided feedback about movement form. The feedback statements, provided either after every (100%) or every third (33%) practice trial, were similar in content but induced either an internal focus (body-movement related) or external focus (movement-effect related). The results demonstrated that learning of the movement form was enhanced by external-focus feedback after every trial (100%) relative to external-focus feedback after every third trial (33%) or internal-focus feedback (100%, 33%), as demonstrated by immediate and delayed transfer tests without feedback. There was no difference between the two internal-focus feedback groups. These findings indicate that the attentional focus induced by feedback is an important factor in determining the effectiveness of different feedback frequencies. We argue that the informational properties of feedback cannot sufficiently account for these and related findings, and suggest that the attentional role of feedback be given greater consideration in future studies.

A Comparative Study of Outcomes for Endoscopic Diverticulotomy versus External Diverticulectomy

PubMed Central

Shahawy, Sarrah; Janisiewicz, Agnieszka M.; Annino, Don; Shapiro, Jo

2014-01-01

Objectives Current literature on the treatment of Zenker's Diverticulum (ZD) favors the use of various endoscopic procedures over external surgical techniques for patients, arguing that endoscopic approaches reduce intraoperative time and anesthesia, length of hospital stay, and days until oral diet is restarted. However, such techniques often have higher symptomatic recurrence rates and require further interventions. Because of our experience with both endoscopic diverticulotomy (ENDO) and external diverticulectomy (EXT) using the GIA-stapler, we sought to compare these two procedures in terms of in-hospital parameters, complications, return to normal diet, and rates of symptom recurrence. Study Design Case series with chart review. Setting Academic tertiary care hospital. Subjects Patients with Zenker's diverticulum who underwent surgical repair. Methods Retrospective analysis of 67 patients seen at Brigham and Women's Hospital between 1990 and 2012 with Zenker's diverticulum who underwent either an endoscopic Zenker's procedure (36) or an external stapler-assisted diverticulectomy with cricopharyngeal myotomy (31). Results Although the external stapler-assisted procedure for ZD does carry a longer intra-operative time and a slightly longer hospital stay than the endoscopic approach, it provides similar days until initiation of an oral diet and a similar incidence of post-operative complications. Further, it is superior to the endoscopic approach when one considers its much lower rate of symptomatic recurrence and need for revision procedures. Conclusion We argue that the external stapler-assisted diverticulectomy with cricopharyngeal myotomy should be considered as a viable treatment in patients who need definitive, single-session treatment for ZD, especially to prevent life-threatening aspiration pneumonia.

The extent to which renal progression after acute kidney injury (AKI) arises from an initial step drop in kidney function (incomplete recovery), or from a long-term trajectory of subsequent decline, is unclear. This makes it challenging to plan or time post-discharge follow-up. This study of 14651 hospital survivors in 2003 (1966 with AKI, 12685 no AKI) separates incomplete recovery from subsequent renal decline by using the post-discharge estimated glomerular filtration rate (eGFR) rather than the pre-admission as a new reference point for determining subsequent renal outcomes. Outcomes were sustained 30% renal decline and de novo CKD stage 4, followed from 2003-2013. Death was a competing risk. Overall, death was more common than subsequent renal decline (37.5% vs 11.3%) and CKD stage 4 (4.5%). Overall, 25.7% of AKI patients had non-recovery. Subsequent renal decline was greater after AKI (vs no AKI) (14.8% vs 10.8%). Renal decline after AKI (vs no AKI) was greatest among those with higher post-discharge eGFRs with multivariable hazard ratios of 2.29 (1.88-2.78); 1.50 (1.13-2.00); 0.94 (0.68-1.32) and 0.95 (0.64-1.41) at eGFRs of 60 or more; 45-59; 30-44 and under 30, respectively. The excess risk after AKI persisted over ten years of study, irrespective of AKI severity, or post-episode proteinuria. Thus, even if post-discharge kidney function returns to normal, hospital admission with AKI is associated with increased renal progression that persists for up to ten years. Follow-up plans should avoid false reassurance when eGFR after AKI returns to normal. Copyright © 2017 International Society of Nephrology. Published by Elsevier Inc. All rights reserved.

Post-Test Analysis of a 10-Year Sodium Heat Pipe Life Test

Rosenfeld, John H.; Locci, Ivan E.; Sanzi, James L.; Hull, David R.; Geng, Steven M.

2011-01-01

High-temperature heat pipes are being evaluated for use in energy conversion applications such as fuel cells, gas turbine re-combustors, Stirling cycle heat sources; and with the resurgence of space nuclear power both as reactor heat removal elements and as radiator elements. Long operating life and reliable performance are critical requirements for these applications. Accordingly, long-term materials compatibility is being evaluated through the use of high-temperature life test heat pipes. Thermacore, Inc., has carried out a sodium heat pipe 10-year life test to establish long-term operating reliability. Sodium heat pipes have demonstrated favorable materials compatibility and heat transport characteristics at high operating temperatures in air over long time periods. A representative one-tenth segment Stirling Space Power Converter heat pipe with an Inconel 718 envelope and a stainless steel screen wick has operated for over 87,000 hr (10 years) at nearly 700 C. These life test results have demonstrated the potential for high-temperature heat pipes to serve as reliable energy conversion system components for power applications that require long operating lifetime with high reliability. Detailed design specifications, operating history, and post-test analysis of the heat pipe and sodium working fluid are described. Lessons learned and future life test plans are also discussed.

Purpose The structure and development of an innovative clinical pharmacogenetics post-graduate year 2 (PGY2) ASHP-accredited residency program is described. Summary The advent of the era of genomics has left practitioners wondering how to interpret the data obtained from sequencing and genotyping patients. In order to train the next leaders in the area of implementing pharmacogenetics, St. Jude Children’s Research Hospital established the first accredited residency program in clinical pharmacogenetics. The 12-month long PGY2 residency was created in accordance with the ASHP standards for advanced practice residencies. The resident learns to optimize patient outcomes through the expert provision of evidence-based, patient-centered precision medicine as an integral part of an interdisciplinary team. The resident gains hands-on experience in a dynamic environment regarding all aspects of running a clinical pharmacogenetics service. Since the first resident graduated in 2012, the program has graduated one resident each year. Conclusion To fill a need for pharmacists trained in pharmacogenetics, an innovative PGY2 residency in clinical pharmacogenetics was successfully developed. Upon completion of the program, residents are equipped with the clinical skills and necessary experience to drive precision medicine forward and lead the implementation of pharmacogenetics in various healthcare settings.

PEG spacer gel and adaptive planning vs single plan in external prostate radiotherapy—clinical dosimetry evaluation

PubMed Central

2015-01-01

Objective: Spacer gel is used to reduce the rectal dose in prostate radiotherapy. It is injected to increase the distance between the prostate and rectum. During the course of external radiotherapy treatment, physiological changes in rectal volume exist. When using polyethylene glycol material, such as DuraSeal® (Covidien, Mansfield, MA), gel resorption also occurs. Together, these factors alter the original dose plan distribution. Methods: External dose planning and calculations were simulated using images acquired from 10 patients who were treated with brachytherapy and gel. The CT series was taken relative to gel injection: pre 1 day, post 1 day, post 1 month and post 2 months. Adaptive planning was compared with a single plan. Results: Adaptive planning shows better results compared with the single plan used in the total treatment course; however, the effect is minor. Conclusion: Gel usage is clearly favourable to rectal DVH. Using adaptive planning with gel improves rectal DVH but is not necessary according to this study. Advances in knowledge: Spacer gel is used in prostate radiotherapy to increase distance between the prostate and the rectum, thus reducing the rectal doses. During the treatment course, gel resorption exists which affects the rectal doses. The usefulness of adaptive planning to compensate this resorption effect has not been studied before. PMID:26370300

This article reports the treatment of an 33-year-old female patient with pyknodysostosis by rigid external distraction II midface distraction system. The patient with pyknodysostosis described in this report had severe midfacial hypoplasia. Correction of this by use of routine orthognathic surgery would require osteosynthesis and bone grafting. Risk of infection and/or nonunion after such a surgical procedure was considered too great, and therefore the possibility of treatment by distraction osteogenesis of the maxilla was evaluated. The rigid external distraction II midface distraction system was used to relocate the hypoplastic maxilla at anterior-inferior projection. Distraction osteogenesis should be considered as the primary reconstructive method for maxillofacial deformities in patients with sclerosing bone dysplasias, since this is the second reported case treated successfully with rigid external distraction.

Dental hygiene student experiences in external placements in Australia.

While placements in external locations are being increasingly used in dental education globally, few studies have explored the student learning experience at such placements. The purpose of this study was to investigate student experiences while on external placement in a baccalaureate dental hygiene program. A self-reporting questionnaire was distributed to final-year dental hygiene students (n=77) at the University of Newcastle, Australia, in 2010. The questionnaire included questions regarding the type of placement, experiences offered, supervision, resources available, and lasting impressions. Responding students were generally positive about their external placement experience and indicated that the majority of facilities provided them with the opportunity to provide direct patient care and perform clinical tasks typical of a practicing hygienist. However, there was a statistically significant difference in their opinions about discipline-focused and community placements. Students indicated that their external placement experience provided opportunities to learn more about time and patient management, including hands-on experience with specific clinical tasks. Ongoing evaluations are necessary to ensure that external placements meet both student needs and intended learning outcomes within dental hygiene programs.

Externalizing behaviors of Ukrainian children: The role of parenting.

PubMed

Burlaka, Viktor

2016-04-01

The purpose of this study was to assess the association of positive and negative parenting with child externalizing problems. Quantitative data were collected during face-to-face interviews with 320 parents of children 9-16 years of age (50% males) in 11 communities in Eastern, Southern, and Central Ukraine. The study estimated the relationship between parenting practices and child externalizing behaviors such as aggression, delinquency, and attention problems. Results revealed that positive parenting, child monitoring, and avoidance of corporal punishment were associated with fewer child externalizing symptoms. Results also indicated that child male gender and single parenting had significant and positive association with child externalizing behaviors. This study extends international psychosocial knowledge on children and families. These findings can be used to design programs and foster dialogs about the role of family and social environments in the development of externalizing disorder among researchers, representatives of governmental and nongovernmental organizations, and mass media that work with child abuse prevention in Ukraine.

1989-03-13

STS029-72-059 (13 March 1989) --- This 70mm photograph, taken by Astronaut James P. Bagian 16 minutes and 7 seconds after liftoff of Discovery, shows the external fuel tank (ET) against the background of Earth. The tank is falling away from the orbiter following ET separation. The left side shows the burn scar above the solid rocket booster (SRB) forward attach point. The burn is caused by the forward SRB separation motors firing during SRB separation. Post 51-L analysis of the thermal and pressure effects of the separation motor exhaust plume indicate that the scarring is not a safety hazard. However, photographs such as this one were requested for additional missions in order to document the phenomenon and corroborate this conclusion. The photo was made at 15:13:07 GMT, March 13, 1989. It was among the visuals used by the crew at its Mar. 28, 1989 post-flight press conference.

The purpose of this report is to present a 5 year experience in electrophysiologically guided surgical treatment of post-infarction ventricular tachycardia (VT) in a consecutive series of 39 patients. In every case the arrhythmia was not responsive to pluripharmacological therapy. The diagnostic steps included preoperative endocardial, intraoperative epi- and endocardial mapping, automatically carried out when possible. Surgical techniques were: classic Guiraudon's encircling endocardial ventriculotomy (EEV), partial EEV, endocardial resection (ER), cryoablation or combined procedures. The hospital mortality was of 4 patients (10%). During the follow-up period (1-68 mo), 4 patients (11%) died of cardiac non-VT related causes. Among the survivors, 90% are in sinus rhythm. The authors consider electrophysiologically guided surgery a safe and reliable method for the treatment of post-infarction VT and suggest more extensive indications. They stress the importance of automatic mapping in pleomorphic and non-sustained VT, and the necessity of tailoring the surgical technique to the characteristics of each case.

Child Diurnal Cortisol Rhythms, Parenting Quality, and Externalizing Behaviors in Preadolescence

This study examined a neurobiologically–informed model of the emergence of child externalizing behaviors in an ethnically diverse community sample of 232 9–12 year old children. Replicating extensive prior research, our analyses revealed that parents’ inconsistent discipline and poor quality monitoring were predictive of child externalizing behavior. In addition, poor parental monitoring, but not inconsistent discipline, was associated with children having a significantly flatter morning–to–evening cortisol slope, which was in turn, related to higher levels of externalizing behaviors. An indirect effect of parental monitoring on externalizing behaviors, through child diurnal cortisol rhythms, was also supported. These findings highlight the role of the hypothalamic–pituitary–adrenal (HPA) axis and its hormonal end product, cortisol, in the relationship between the caregiving environment and the development of externalizing behaviors.

The purpose of this 15-year longitudinal study was to assess the effects of maternal HIV/AIDS on child/adolescent career readiness and externalizing behaviors. Interviews were conducted with 66 pairs of healthy children and their mothers living with HIV/AIDS (MLH), who are participants in the Parents And children Coping Together (PACT) project begun in 1997. All study participants were English or Spanish speaking. About half (48.5%) of the youth were female. Maternal health status (e.g., viral load biomedical marker, illness symptoms, physical functioning and depression) and child/adolescent outcomes (e.g., career readiness, conduct disorder, drug use, sexual behaviors, parent attachment and youth autonomy) were assessed over 20 time-points. Individual growth and GEE logistic regression models showed lower variability in maternal viral load was positively associated with better career readiness and parent attachment among adolescent/young adults. Externalizing behaviors (conduct disorder, alcohol and crystal methamphetamine use) were positively associated with maternal depression. Adolescent coping efficacy was shown to be a protective factor when applied to models on career readiness. Stability in MLH health positively affects children's career readiness over time, particularly career planning and career choices. The finding that adolescent coping efficacy may act as a protective factor against poor career planning has important implications for developing interventions to assist children in coping with parental HIV.

The MNA (Mini Nutritional Assessment) is known as a prognosis factor in older population. We analyzed the prognostic value for one-year mortality of MNA items in older patients with cancer treated with chemotherapy as the basis of a simplified prognostic score. The prospective derivation cohort included 606 patients older than 70 years with an indication of chemotherapy for cancers. The endpoint to predict was one-year mortality. The 18 items of the Full MNA, age, gender, weight loss, cancer origin, TNM, performance status and lymphocyte count were considered to construct the prognostic model. MNA items were analyzed with a backward step-by-step multivariate logistic regression and other items were added in a forward step-by-step regression. External validation was performed on an independent cohort of 229 patients. At one year 266 deaths had occurred. Decreased dietary intake (p = 0.0002), decreased protein-rich food intake (p = 0.025), 3 or more prescribed drugs (p = 0.023), calf circumference <31 cm (p = 0.0002), tumor origin (p<0.0001), metastatic status (p = 0.0007) and lymphocyte count <1500/mm3 (0.029) were found to be associated with 1-year mortality in the final model and were used to construct a prognostic score. The area under curve (AUC) of the score was 0.793, which was higher than the Full MNA AUC (0.706). The AUC of the score in validation cohort (229 subjects, 137 deaths) was 0.698. Key predictors of one-year mortality included cancer cachexia clinical features, comorbidities, the origin and the advanced status of the tumor. The prognostic value of this model combining a subset of MNA items and cancer related items was better than the full MNA, thus providing a simple score to predict 1-year mortality in older patients with an indication of chemotherapy.

Chemical Waste Landfill Annual Post-Closure Care Report Calendar Year 2014

The CWL is a 1.9-acre remediated interim status landfill located in the southeastern corner of SNL/NM Technical Area III (Figures 2-1 and 2-2) undergoing post-closure care in accordance with the PCCP (NMED October 2009 and subsequent revisions). From 1962 until 1981, the CWL was used for the disposal of chemical and solid waste generated by SNL/NM research activities. Additionally, a small amount of radioactive waste was disposed of during the operational years. Disposal of liquid waste in unlined pits and trenches ended in 1981, and after 1982 all liquid waste disposal was terminated. From 1982 through 1985, only solid wastemore » was disposed of at the CWL, and after 1985 all waste disposal ended. The CWL was also used as a hazardous waste drum-storage facility from 1981 to 1989.

To analyze the rate of successful external cephalic versions in our center and caesarean sections that would be avoided with the use of external cephalic versions. From January 2012 to March 2016 external cephalic versions carried out at our center, which were a total of 52. We collected data about female age, gestational age at the time of the external cephalic version, maternal body mass index (BMI), fetal variety and situation, fetal weight, parity, location of the placenta, amniotic fluid index (ILA), tocolysis, analgesia, and newborn weight at birth, minor adverse effects (dizziness, hypotension and maternal pain) and major adverse effects (tachycardia, bradycardia, decelerations and emergency cesarean section). 45% of the versions were unsuccessful and 55% were successful. The percentage of successful vaginal delivery in versions was 84% (4% were instrumental) and 15% of caesarean sections. With respect to the variables studied, only significant differences in birth weight were found; suggesting that birth weight it is related to the outcome of external cephalic version. Probably we did not find significant differences due to the number of patients studied. For women with breech presentation, we recommend external cephalic version before the expectant management or performing a cesarean section. The external cephalic version increases the proportion of fetuses in cephalic presentation and also decreases the rate of caesarean sections.

Using a risk-resilience framework, this study examined how varying levels of exposure to a natural disaster (EF-4 tornado) and children's characteristics (sex; anxiety) influenced the behavioral and psychological adjustment of children who shared a common risk factor predisaster (elevated aggression) prior to exposure through 1-year postdisaster. Participants included 360 children in Grades 4-6 (65% male; 78% African American) and their parents from predominantly low-income households who were already participating in a longitudinal study of indicated prevention effects for externalizing outcomes when the tornado occurred in 2011. Fourth-grade children who were screened for overt aggressive behavior were recruited in 3 annual cohorts (120 per year, beginning in 2009). Parent-rated aggression and internalizing problems were assessed prior to the tornado (Wave 1), within a half-year after the tornado (Wave 2), and at a 1-year follow-up (Wave 3). Children and parents rated their exposure to aspects of tornado-related traumatic experiences at Wave 3. Children displayed less reduction on aggression and internalizing problems if the children had experienced distress after the tornado or fears for their life, in combination with their pre-tornado level of anxiety. Higher levels of children's and parents' exposure to the tornado interacted with children's lower baseline child anxiety to predict less reduction in aggression and internalizing problems 1 year after the tornado. Higher levels of disaster exposure negatively affected at-risk children's level of improvement in aggression and internalizing problems, when life threat (parent- and child-reported) and child-reported distress after the tornado were moderated by baseline anxiety.

We demonstrate a multi-wavelength distributed feedback (DFB) quantum cascade laser (QCL) operating in a lensless external micro-cavity and achieve switchable single-mode emission at three distinct wavelengths selected by the DFB grating, each with a side-mode suppression ratio larger than 30 dB. Discrete wavelength tuning is achieved by modulating the feedback experienced by each mode of the multi-wavelength DFB QCL, resulting from a variation of the external cavity length. This method also provides a post-fabrication control of the lasing modes to correct for fabrication inhomogeneities, in particular, related to the cleaved facets position.

Minimal-post-processing 320-Gbps true random bit generation using physical white chaos.

2017-02-20

Chaotic external-cavity semiconductor laser (ECL) is a promising entropy source for generation of high-speed physical random bits or digital keys. The rate and randomness is unfortunately limited by laser relaxation oscillation and external-cavity resonance, and is usually improved by complicated post processing. Here, we propose using a physical broadband white chaos generated by optical heterodyning of two ECLs as entropy source to construct high-speed random bit generation (RBG) with minimal post processing. The optical heterodyne chaos not only has a white spectrum without signature of relaxation oscillation and external-cavity resonance but also has a symmetric amplitude distribution. Thus, after quantization with a multi-bit analog-digital-convertor (ADC), random bits can be obtained by extracting several least significant bits (LSBs) without any other processing. In experiments, a white chaos with a 3-dB bandwidth of 16.7 GHz is generated. Its entropy rate is estimated as 16 Gbps by single-bit quantization which means a spectrum efficiency of 96%. With quantization using an 8-bit ADC, 320-Gbps physical RBG is achieved by directly extracting 4 LSBs at 80-GHz sampling rate.

This study examined whether executive functions (EFs) might be common features of internalizing and externalizing behavior problems across development. We examined relations between three EF latent variables (a common EF factor and factors specific to updating working memory and shifting sets), constructed from nine laboratory tasks administered at age 17, to latent growth intercept (capturing stability) and slope (capturing change) factors of teacher- and parent-reported internalizing and externalizing behaviors in 885 individual twins aged 7 to 16 years. We then estimated the proportion of intercept-intercept and slope-slope correlations predicted by EF as well as the association between EFs and a common psychopathology factor (P factor) estimated from all 9 years of internalizing and externalizing measures. Common EF was negatively associated with the intercepts of teacher-rated internalizing and externalizing behavior in males, and explained 32% of their covariance; in the P factor model, common EF was associated with the P factor in males. Shifting-specific was positively associated with the externalizing slope across sex. EFs did not explain covariation between parent-rated behaviors. These results suggest that EFs are associated with stable problem behavior variation, explain small proportions of covariance, and are a risk factor that that may depend on gender.

Functional outcome of knee arthrodesis with a monorail external fixator.

Several methods for obtaining knee arthrodesis have been described in the literature and world; over, the commonest cause for arthrodesis is a failed arthroplasty. Less commonly, as in this series, post-infective or traumatic causes may also require a knee fusion wherein arthroplasty may not be indicated. We present salient advantages along with the radiological and functional outcome of twenty four patients treated with a single monorail external fixator. All patients went on develop fusion at an average of 5.4 months with an average limb length discrepancy of 3 cm (1.5-6 cm). Improvements in functional outcome as assessed by the lower extremity functional score (LEFS), and the SF-36 was significant (p = 0.000). Knee arthrodesis with a single monorail external fixator is a reasonable single-staged salvage option in patients wherein arthroplasty may not be the ideal choice. The outcome, though far from ideal, is definitely positive and predictable.

Ovarian fluid allows directional cryptic female choice despite external fertilization

Alonzo, Suzanne H.; Stiver, Kelly A.; Marsh-Rollo, Susan E.

2016-01-01

In species with internal fertilization, females can favour certain males over others, not only before mating but also within the female's reproductive tract after mating. Here, we ask whether such directional post-mating (that is, cryptic) female mate choice can also occur in species with external fertilization. Using an in vitro sperm competition experiment, we demonstrate that female ovarian fluid (ovarian fluid) changes the outcome of sperm competition by decreasing the importance of sperm number thereby increasing the relative importance of sperm velocity. We further show that ovarian fluid does not differentially affect sperm from alternative male phenotypes, but generally enhances sperm velocity, motility, straightness and chemoattraction. Under natural conditions, female ovarian fluid likely increases the paternity of the preferred parental male phenotype, as these males release fewer but faster sperm. These results imply females have greater control over fertilization and potential to exert selection on males in species with external fertilization than previously thought possible. PMID:27529581

To assess the impact and sustainability of health, water, and sanitation interventions in Bolivia six years post-project. A mixed-method (qualitative-quantitative) study was conducted in 14 rural intervention and control communities in Bolivia in November 2008, six years after the completion of interventions designed to improve knowledge and practices related to maternal and child health and nutrition, community water systems, and household water and sanitation facilities. The degree to which participants had sustained the community and household practices promoted by the interventions was a particular focus. Community site visits were made to evaluate the status (functional condition) and sustainability (state of maintenance and repair) of community and household water and sanitation infrastructure. Key informant interviews and focus group discussions were conducted to assess knowledge and practices, and perceptions about the value of the interventions to the community. Six years post-project, participants remained committed to sustaining the practices promoted in the interventions. The average rating for the functional condition of community water systems was 42% higher than the average rating in control communities. In addition, more than two-thirds of households continued to practice selected maternal and child health behaviors promoted by the interventions (compared to less than half of the households in the control communities). Communities that received integrated investments (development and health) seemed to sustain the practices promoted in the interventions better than communities that received assistance in only one of the two sectors. Infrastructure for community water systems and household water and sanitation facilities was better built and maintained, and selected maternal and child health behaviors practiced more frequently, in intervention communities versus control communities.

Children may suffer from post-traumatic stress disorder after disaster. There was a severe tsunami following an undersea earthquake off the Sumatra coast of Indonesia. There were 20,000 children in 6 southwestern provinces of Thailand who were possibly affected. To study the prevalence of post-traumatic stress disorder (PTSD) in Thai students in the area affected by the December 26th, 2004 tsunami disaster, Thailand. One thousand six hundred and fifteen surviving students from two schools in Takua Pa district located in Phang-nga Province, Thailand participated in this longitudinal study. Screening was done by using Pediatric Symptom Checklists part II (PSC-II), Childhood Depressive Intervention (CDI) and the Revised Child Impact of Events Scales (CRIES 8). PTSD was diagnosed by child and adolescent psychiatrists by using criteria of DSM-IV. The intervention included psychological first aid, psycho-education, cognitive-behavioral therapy, medication in severe cases, group support for students, parents and teachers which was done, beginning at 10 days after the tsunami disaster. Data were analyzed by using SPSS version 12.0. The prevalence rates of PTSD in the students facing the tsunami disaster in the study group were 573, 46.1, 31.6, 7.6, 4.5, 3.9 and 2.7% at 6 weeks, 6 months, 1 year, 2 years, 3 years, 4 years and 5 years after the disaster, respectively. Female to male ratio was 1.7: 1. The peak age was 9-10 years old. The top five on the list of symptoms in PTSD were distress with cue, intrusive thought, functioning impairment, startled response, terrified and hyper vigilance. Seven cases (3.1%) were diagnosed partial PTSD, still exhibited a wide range of PTSD symptoms but did not fulfill the DSM-IV diagnostic criteria. The top five on the list of symptoms in partial PTSD were avoiding thought/feelings, terrified, avoiding place/activities, distress with cue and startled response. The prevalence of PTSD among tsunami victims was 57.3% at 6 weeks after the

This is the first long-term randomized controlled trial to evaluate dentin-like glass fiber posts (GFPs) compared with rather rigid titanium posts (TPs) for post-endodontic restoration of severely damaged endodontically treated teeth with 2 or fewer remaining cavity walls. Ninety-one subjects in need of post-endodontic restorations were randomly assigned to receive either a tapered GFP (n = 45) or TP (n = 46). Posts were adhesively luted by using self-adhesive resin cement, followed by composite core build-up and preparation of 2-mm ferrule design. Primary end point was loss of restoration for any reason. Kaplan-Meier curves were constructed, and log-rank test was calculated (P < .05). After a follow-up of 132 months, 17 GFP and 20 TP restorations survived, and 19 failed (12 GFP, 7 TP). Failure modes for GFP were root fracture (n = 4), core fracture (n = 1), secondary caries (n = 1), endodontic failure (n = 2), extraction because of tooth mobility grade III associated with insufficient design of removable partial denture (n = 1), tooth fracture (n = 1), and changes in treatment plan (n = 2); failure modes for TP were endodontic failure (n = 5), root fracture (n = 1), and 1 extraction for other reasons. Cumulative survival probability was 58.7% for GFP and 74.2% for TP. When using self-adhesively luted prefabricated posts, resin composite core build-up, and 2-mm ferrule to reconstruct severely damaged endodontically treated teeth, tooth survival is not influenced by post rigidity. Survival decreased rapidly after 8 years of observation in both groups. Copyright © 2017 American Association of Endodontists. Published by Elsevier Inc. All rights reserved.

Bobath or motor relearning programme? A follow-up one and four years post stroke.

2003-11-01

The purpose of this follow-up one and four years post stroke was to find out whether the initial physiotherapy approach had had any long-term effects on mortality, motor function, postural control, activities of daily living, life quality, follow-up from community services and living conditions. A randomized controlled trial of first time ever stroke patients. Group 1 (n = 33) and group 2 (n = 28) had initial physiotherapy according to the Motor Relearning Programme and Bobath, respectively. The Motor Assessment Scale (MAS), the Sødring Motor Evaluation Scale (SMES), the Barthel ADL Index, the Nottingham Health Profile (NHP) and Berg Balance Scale were used. The following parameters were also registered: incidence of new strokes, other diseases, use of assistive devices, the patient's accommodation and use of services from the community. The mortality rates were similar in the two groups. In both groups the motor function, postural control and ADL had decreased rapidly, leaving many of the patients dependent and with a high risk of falling. Life quality had increased compared to the acute stage, but was still low in comparison with healthy persons. Patients in both groups lived at home, but were dependent on help from relatives and community services. Physiotherapy as follow-up service was seldom used. The initial physiotherapy approach did not seem to have a major influence on the patients' ability to cope in the long-term. This follow-up at one and four years post stroke showed no major influence of two different initial physiotherapy regimens on long-term function. The study confirmed a rapid deterioration of ADL and motor function and an increased dependence on relatives. The study reveals a gap between the intense treatment in the acute phase and little or no follow-up of physiotherapy treatment or other rehabilitation activities later.

The process of striving for an ordinary, everyday life, in young children living with cancer, at six months and one year post diagnosis.

Health care focus is shifting from solely looking at surviving cancer to elements of attention relating to living with it on a daily basis.The young child's experiences are crucial to providing evidence based care. The aim of this study was to explore the everyday life of young children as expressed by the child and parents at six months and one year post diagnosis. Interviews were conducted with children and their parents connected to a paediatric oncology unit in Southern Sweden. A qualitative content analysis of interview data from two time points, six months and one year post diagnosis, was carried out. The process of living with cancer at six months and at one year post diagnosis revealed the child's striving for an ordinary, everyday life. Experiences over time of gaining control, making a normality of the illness and treatment and feeling lonely were described. Nurses have a major role to play in the process of striving for a new normal in the world post-diagnosis, and provide essential roles by giving the young child information, making them participatory in their care and encouraging access to both parents and peers. Understanding this role and addressing these issues regularly can assist the young child in the transition to living with cancer. Longitudinal studies with young children are vital in capturing their experiences through the cancer trajectory and necessary to ensure quality care. Copyright © 2014 Elsevier Ltd.

General relativity extensions based on renormalization group effects are motivated by a known physical principle and constitute a class of extended gravity theories that have some unexplored unique aspects. In this work we develop in detail the Newtonian and post-Newtonian limits of a realization called renormalization group extended general relativity (RGGR). Special attention is given to the external potential effect, which constitutes a type of screening mechanism typical of RGGR. In the Solar System, RGGR depends on a single dimensionless parameter ν¯⊙, and this parameter is such that for ν¯⊙=0 one fully recovers GR in the Solar System. Previously this parameter was constrained to be |ν¯ ⊙|≲10-21 , without considering the external potential effect. Here we show that under a certain approximation RGGR can be cast in a form compatible with the parametrized post-Newtonian (PPN) formalism, and we use both the PPN formalism and the Laplace-Runge-Lenz technique to put new bounds on ν¯⊙, either considering or not the external potential effect. With the external potential effect the new bound reads |ν¯ ⊙|≲10-16 . We discuss the possible consequences of this bound on the dark matter abundance in galaxies.

The relative importance of internal and external letter features of words in children's developing reading was investigated to clarify further the nature of early featural analysis. In Experiment 1, 72 6-, 8-, and 10-year-olds read aloud words displayed as wholes, external features only (central features missing, thereby preserving word shape information), or internal features only (central features preserved). There was an improvement in the processing of external features compared with internal features as reading experience increased. Experiment 2 examined the processing of the internal and external features of words employing a forward priming paradigm with 60 8-, 10-, and 12-year-olds. Reaction times to internal feature primes were equivalent to a nonprime blank condition, whereas responses to external feature primes were faster than those to the other two prime types. This advantage for the external features of words is discussed in terms of an early and enduring role for processing the external visual features in words during reading development.

Even though the use of a 25 gauge or smaller Quincke needle is recommended for spinal anesthesia to reduce post-dural puncture headache in Korea, lumbar puncture in older patients using a 25 gauge or smaller Quincke needle can be difficult. However, most previous studies concerning post-dural puncture headache have chosen children, parturients, and young adults as study participants. The study compared post-dural puncture headache, post-operative back pain, and the number of lumbar puncture attempts using a 23 or 25 gauge Quincke needle for spinal anesthesia of Korean patients >60-years-of-age. Randomized, double-blinded controlled trial. The 53 participants who underwent orthopedic surgery under spinal anesthesia were recruited by informed notices from December 2006 through August 2007 at a 200-bed general hospital located in Kyunggido. Inclusion criteria were an age >60 years, ASA I-II, and administration of patient controlled analgesia for the first 48 h post-operatively. The 53 patients were randomly allocated to either the experimental (23 gauge Quincke needle) or control group (25 gauge Quincke needle). All patients had 24 h bed rest post-operatively. Post-dural puncture headache was assessed by the Dittmann Scale and post-operative back pain was assessed by a visual analogue scale at 24, 48, and 72 h post-operatively. The statistical methods included the Mann-Whitney U-test and Spearman correlation. There were no differences in post-dural puncture headache, and post-operative back pain at 24, 48, and 72 h post-operatively, and no differences in the number of lumbar punctures, with the 23 and 25 gauge Quincke needle. Forty-eight hour post-operative back pain was positively associated with the number of lumbar punctures (p=.036) and age (p=.040). There were no statistically significant associations among post-dural puncture headache, the number of lumbar punctures, and 48 h post-operative back pain. Pre-operative back pain was positively associated with 48 h

Clinical pharmacists can help prevent medication errors. However, data are scarce on their role in preventing medication prescription errors in the post-operative period, a high-risk period, as at least two prescribers can intervene, the surgeon and the anesthetist. We aimed to describe and quantify clinical pharmacist' intervention (PIs) during validation of drug prescriptions on a computerized physician order entry system in a post-surgical and post-transplantation ward. We illustrate these interventions, focusing on one clearly identified recurrent problem. In a prospective study lasting 4 years, we recorded drug-related problems (DRPs) detected by pharmacists and whether the physician accepted the PI when prescription modification was suggested. Among 7005 orders, 1975 DRPs were detected. The frequency of PIs remained constant throughout the study period, with 921 PIs (47%) accepted, 383 (19%) refused and 671 (34%) not assessable. The most frequent DRP concerned improper administration mode (26%), drug interactions (21%) and overdosage (20%). These resulted in a change in the method of administration (25%), dose adjustment (24%) and drug discontinuation (23%) with 307 drugs being concerned by at least one PI. Paracetamol was involved in 26% of overdosage PIs. Erythromycin as prokinetic agent, presented a recurrent risk of potentially severe drug-drug interactions especially with other QT interval-prolonging drugs. Following an educational seminar targeting this problem, the rate of acceptation of PI concerning this DRP increased. Pharmacists detected many prescription errors that may have clinical implications and could be the basis for educational measures. © 2012 The Authors.

To summarise post-licensure safety surveillance over more than 4 years of routine use of the human papillomavirus-16/18-AS04-adjuvanted vaccine (HPV-16/18 vaccine: Cervarix®, GlaxoSmithKline, Belgium). We describe global post-licensure passive surveillance data based on routine pharmacovigilance from 18 May 2007 until 17 November 2011 and enhanced surveillance implemented during the 2-year national immunisation programme in the UK (school years 2008-2010). Spontaneous reports from countries worldwide showed a similar pattern for the most frequently reported adverse events after HPV-16/18 vaccination. No patterns or trends were observed for potential immune-mediated diseases after vaccination. Observed incidences of Bell's palsy and confirmed Guillain-Barré syndrome were within the expected range in the general population. Outcomes of pregnancy in women who were inadvertently exposed to HPV-16/18 vaccine during pregnancy, were in line with published reports for similar populations. Enhanced surveillance of adverse events in the UK triggered a review of cases of anaphylaxis, angioedema and syncope reports, leading to an update to the prescribing information. Collaborative partnerships between industry and national regulatory agencies facilitated rapid notification and transfer of safety information, allowing for rapid responses in the event of a safety signal of adverse event of concern. More than 4 years of post-licensure experience may provide confidence to providers and the public about the safety profile of HPV-16/18 vaccine in routine use. The safety profile appears to be consistent with pre-licensure data reporting that HPV-16/18 vaccine has an acceptable benefit-risk profile in adolescent girls and women. © 2014 The Authors.

The aim of this study was to examine predictors of mortality in patients 5 years after ischemic stroke, focusing on cognitive impairment, vulnerability, and vascular risk factors assessed at 6 months post stroke. Patients from the Action on Secondary Prevention Interventions and Rehabilitation in Stroke (ASPIRE-S) cohort were followed up 5 years post ischemic stroke. Vascular risk factors, cognitive impairment, and vulnerability were assessed at 6 months post stroke. Cognitive impairment was assessed using a cutoff score lower than 26 on the Montreal Cognitive Assessment (MoCA). Vulnerability was defined as a score of 3 or higher on the Vulnerable Elders Scale (VES). Mortality and date of death were ascertained using hospital records, death notifications, and contact with general practitioners. Predictors of mortality were explored using multivariate Cox proportional hazards models. Adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) are presented. Sixty-three of 256 patients (24.6%) assessed at 6 months post stroke had died within 5 years. Cognitive impairment (HR [95% CI]: 2.19 [1.42-3.39]), vulnerability (HR [95% CI]: 5.23 [2.92-9.36]), atrial fibrillation (AF) (HR [95% CI]: 2.31 [1.80-2.96]), and dyslipidemia (HR [95% CI]: 1.90 [1.10-3.27]) were associated with increased risk of 5-year mortality. Vulnerability, cognitive impairment, AF, and dyslipidemia at 6 months were associated with increased risks of mortality 5 years post ischemic stroke. Identification and management of these risk factors should be emphasized in poststroke care. Copyright © 2018 National Stroke Association. Published by Elsevier Inc. All rights reserved.

This study examined a neurobiologically informed model of the emergence of child externalizing behaviors in an ethnically diverse community sample of 232 9-12 year old children. Replicating extensive prior research, our analyses revealed that parents' inconsistent discipline and poor quality monitoring were predictive of child externalizing behavior. In addition, poor parental monitoring, but not inconsistent discipline, was associated with children having a significantly flatter morning-to-evening cortisol slope, which was in turn, related to higher levels of externalizing behaviors. An indirect effect of parental monitoring on externalizing behaviors, through child diurnal cortisol rhythms, was also supported. These findings highlight the role of the hypothalamic-pituitary-adrenal (HPA) axis and its hormonal end product, cortisol, in the relationship between the caregiving environment and the development of externalizing behaviors.

This study investigated the associations of poverty and food insecurity over a 2-year period with internalizing and externalizing problems in a large, community-based sample. A total of 2,810 children were interviewed between ages 4 and 14 years at baseline, and between ages 5 and 16 years at follow-up. Primary caregivers reported on household income, food insecurity, and were administered the Child Behavior Checklist, from which we derived indicators of clinically significant internalizing and externalizing problems. Prevalence ratios for the associations of poverty and food insecurity with behavior problems were estimated. At baseline, internalizing and externalizing problems were significantly more prevalent among children who lived in poor households than in nonpoor households, and among children who lived in food insecure households than in food-secure households. In adjusted analyses, children from homes that were persistently food insecure were 1.47 (95% CI = 1.12 to 1.94) times more likely to have internalizing problems and 2.01 (95% CI = 1.21 to 3.35) times more likely to have externalizing problems compared with children from households that were never food insecure. Children from homes that moved from food secure to insecure were 1.78 (95% CI = 1.07 to 2.94) times more likely to have externalizing problems at follow-up. Persistent food insecurity is associated with internalizing and externalizing problems, even after adjusting for sustained poverty and other potential confounders. These results implicate food insecurity as a novel risk factor for child mental well-being; if causal, this represents an important factor in the etiology of child psychopathology, and potentially a new avenue for prevention.

Serra Calderona Natural Park, a Mediterranean ecosystem, has been in post-fire regeneration for 10 years. To elucidate which helminth community component species of the wood mouse, Apodemus sylvaticus, can be considered biological tags of this process, the influence of intrinsic (host density; host sex and age) and extrinsic factors (site, year, and period of capture; vegetation recovery) on their prevalence and abundance has been analysed, comparing a burned and an unburned area. A total of 564 wood mice (408 from the burned and 156 from the unburned area), from the 2nd to the10th post-fire year, was included in this helminthoecological study. The results suggest that the area in post-fire regeneration is still more vulnerable to periodic environmental changes than the unburned area as deduced from the analysis of the helminth populations of Pseudocatenotaenia matovi, Skrjabinotaenia lobata, Trichuris muris, Eucoleus bacillatus and Aonchotheca annulosa. The intermediate and definitive host populations presented a greater variability to these environmental changes in the burned area (Taenia parva, P. matovi, S. lobata, A. annulosa, Syphacia stroma and S. frederici). In the regenerating area, some behavioural changes in certain populations determined by the host sex are taking place (T. parva, Helgimosomoides polygyrus and S. frederici). During the last years studied, a greater similarity in the populational development of some component species between both areas can be appreciated (H. polygyrus and S. stroma). The role of the wood mouse and its helminth parasites as biological tags of the post-fire regeneration process in Mediterranean ecosystems has been confirmed.

Is 20 years of immobilization, not sufficient to render metacarpophalangeal joints completely useless?--Correction of a 20-year old post-burn palmar contracture: a case report.

This report presents a case of post-burn palmar contracture with flexion contracture of thumb of 20-year duration. The contracture was released and the raw area was covered with split thickness skin graft. Only one 'K' wire in soft tissue was needed to keep all the fingers straight and immobilized, suggestive of intermetacarpal ligamentous contracture. A static night splint was given to maintain the correction. Complete range of movement was achieved in a month with the combination of dynamic splinting and physiotherapy. It was interesting to note that even 20 years of contracted position did not render the metacarpophalangeal joints completely stiff and useless. Probable reasons are discussed.

The purpose of this study was to evaluate the effects of abutment screw length and cyclic loading on the removal torque (RTV) in external hex (EH) and internal hex (IH) implants. Forty screw-retained single crowns were connected to external and internal hex implants. The prepared titanium abutment screws were classified into 8 groups based on the number of threads (n = 5 per group): EH 12.5, 6.5, 3.5, 2.5 and IH 6.5, 5, 3.5, 2.5 threads. The abutment screws were tightened with 20 Ncm torque twice with 10-minute intervals. After 5 minutes, the initial RTVs of the abutment screws were measured with a digital torque gauge (MGT12). A customized jig was constructed to apply a load along the implant long axis at the central fossa of the maxillary first molar. The post-loading RTVs were measured after 16,000 cycles of mechanical loading with 50 N at a 1-Hz frequency. Statistical analysis included one-way analysis of variance and paired t-tests. The post-loading RTVs were significantly lower than the initial RTVs in the EH 2.5 thread and IH 2.5 thread groups (P<.05). The initial RTVs exhibited no significant differences among the 8 groups, whereas the post-loading RTVs of the EH 6.5 and EH 3.5 thread groups were higher than those of the IH 3.5 thread group (P<.05). Within the limitations of this study, the external hex implants with short screw lengths were more advantageous than internal hex implants with short screw lengths in torque maintenance after cyclic loading.

Executive dysfunction is a common consequence of acquired brain injury (ABI), causing significant disability in daily life. This randomized controlled trial investigated the efficacy of Goal Management Training (GMT) in improving executive functioning in patients with chronic ABI. Seventy patients with a verified ABI and executive dysfunction were randomly allocated to GMT (n=33) or a psycho-educative active control condition, Brain Health Workshop (BHW) (n=37). In addition, all participants received external cueing by text messages. Neuropsychological tests and self-reported questionnaires of executive functioning were administered pre-intervention, immediately after intervention, and at 6 months follow-up. Assessors were blinded to group allocation. Questionnaire measures indicated significant improvement of everyday executive functioning in the GMT group, with effects lasting at least 6 months post-treatment. Both groups improved on the majority of the applied neuropsychological tests. However, improved performance on tests demanding executive attention was most prominent in the GMT group. The results indicate that GMT combined with external cueing is an effective metacognitive strategy training method, ameliorating executive dysfunction in daily life for patients with chronic ABI. The strongest effects were seen on self-report measures of executive functions 6 months post-treatment, suggesting that strategies learned in GMT were applied and consolidated in everyday life after the end of training. Furthermore, these findings show that executive dysfunction can be improved years after the ABI.

An external quality-control programme for morphology-based embryo quality assessment, incorporating a standardized embryo grading scheme, was evaluated over a period of 5 years to determine levels of inter-observer reliability and agreement between practising clinical embryologists at IVF centres and the opinions of a panel of experts. Following Guidelines for Reporting Reliability and Agreement Studies, the Gwet index and proportion of positive (Ppos) and negative agreement were calculated. For embryo morphology assessment, a substantial degree of reliability was measured between the centres and the panel of experts (Gwet index: 0.76; 95% CI 0.70 to 0.84). The agreement was higher for good- versus poor-quality embryos. When multinucleation or vacuoles were observed, low levels of reliability were obtained (Ppos: 0.56 and 0.43, respectively). In blastocysts, the characteristic that presented the largest discrepancy was that related to the inner cell mass. In decisions about the final disposition of the embryo, reliability between centre and the panel of experts was moderate (Gwet index: 0.51; 95% CI 0.41 to 0.60). In conclusion, the ability of clinical embryologists to evaluate the presence of multinucleation and vacuoles in the early cleavage embryo, and to determine the category of the inner cell mass in blastocysts, needs to be improved.

A longitudinal, prospective design was used to examine the roles of peer rejection in middle childhood and antisocial peer involvement in early adolescence in the development of adolescent externalizing behavior problems. Both early starter and late starter pathways were considered. Classroom sociometric interviews from ages 6 through 9 years, adolescent reports of peers' behavior at age 13 years, and parent, teacher, and adolescent self-reports of externalizing behavior problems from age 5 through 14 years were available for 400 adolescents. Results indicate that experiencing peer rejection in elementary school and greater involvement with antisocial peers in early adolescence are correlated but that these peer relationship experiences may represent two different pathways to adolescent externalizing behavior problems. Peer rejection experiences, but not involvement with antisocial peers, predict later externalizing behavior problems when controlling for stability in externalizing behavior. Externalizing problems were most common when rejection was experienced repeatedly. Early externalizing problems did not appear to moderate the relation between peer rejection and later problem behavior. Discussion highlights multiple pathways connecting externalizing behavior problems from early childhood through adolescence with peer relationship experiences in middle childhood and early adolescence.

To estimate mortality rate by external causes in Brazil. Mortality national 2010's data corrected by underreport and adjusted by direct method were evaluated by sex according to age, region of residence, race/skin color, education and conjugal situation. The standardized mortality coefficient of external causes is higher among men (178 per thousand inhabitants) than among women (24 per thousand inhabitants), being higher among young men (20 to 29 years old) in all regions and decreasing with aging. The mortality rate reaches almost nine times higher among men comparably to women, being higher in North and Northeast regions. The death incidence by external causes is higher among men (36.4%) than among women (10.9%), meaning 170% more risk for men. The risk is also higher among the youngest: 6.00 for men and 7.36 for women. The main kind of death by external causes among men is aggressions, followed by transport accidents, the opposite of women. Besides sex, age is the more important predictive factor of precocious death by external causes, pointing the need of many and various sectors in order to construct new identities of non violence.

The Association between Positive Parenting and Externalizing Behavior1

The present study examined the role of positive parenting on externalizing behaviors in a longitudinal, genetically informative sample. It often is assumed that positive parenting prevents behavior problems in children via an environmentally mediated process. Alternatively, the association may be due to either an evocative gene-environment correlation, in which parents react to children’s genetically-influenced behavior in a positive way, or a passive gene-environment correlation, where parents passively transmit a risk environment and the genetic risk factor for the behavioral outcome to their children. The present study estimated the contribution of these processes in the association between positive parenting and children’s externalizing behavior. Positive parenting was assessed via observations at ages 7, 9, 14, 24, and 36 months and externalizing behaviors were assessed through parent report at ages 4, 5, 7, 9, 10, 11, and 12 years. The significant association between positive parenting and externalizing behavior was negative, with children of mothers who showed significantly more positive parenting during toddlerhood having lower levels of externalizing behavior in childhood; however, there was not adequate power to distinguish whether this covariation was due to genetic, shared environmental, or nonshared environmental influences.

Global Health Security Agenda: Joint External Evaluation and Legislation-A 1-Year Review.

PubMed

Forzley, Michele

In 2014, the IHR Review Committee recommended moving from exclusive self-evaluation to a combination of domestic and independent experts and began the process in conjunction with stakeholders to develop the Joint External Evaluation tool. The tool was launched in February 2016, and at the 2016 WHA, the IHR Review Committee recommended that all states parties should undertake assessments of their core capacities using the JEE tool and results of other evaluation processes such as the OIE PVS. A goal was set to conduct 50 country JEE assessments prior to WHA 2017. It is notable that legislation was added as a separate element of the JEE tool coupled with 2 indicators. Given the importance of law to the development discourse today, more needs to be done with the JEE with regards to legislation for the benefits of the law to be realized in global health security and overall in health outcomes. As we are at the 1-year anniversary of the tool, and WHO has begun a review of the JEE tool and requests for feedback are circulating, this article focuses on the JEE element of legislation and proposes some simple and substantive fixes. Considering the importance of law in the context of the GHSA, the results of the JEE tool are reviewed, and, drawing on the author's experience with the tool and other IHR and GHSA legal assessments, a case is made for a significant revision of the tool section on legislation and the manner in which the subject of legislation is integrated during the evaluation process.

Microbial infection is one of the most significant causes of ear diseases, but microbial profiles are very diverse according to the diseases and change over time. The purpose of the study was to clarify differences and chronological changes in causative pathogens among infectious ear diseases over the last 20 years, and to identify antibiotic resistance. In total, 1191 isolates were included from patients diagnosed with chronic otitis media without cholesteatoma (COM), cholesteatomatous otitis media (Chole), middle ear effusion (MEE), including acute otitis media and otitis media with effusion, and external otitis (EO). Data were collected periodically for the years 1995, 2000, 2004, 2009, and 2013. Culture results and antibiotic resistance were assessed. The most common microorganism identified was S. aureus. The microbial profiles differed significant among the COM, Chole, and MEE groups (p < 0.001). In contrast, there was no distinct difference between COM and EO (p = 0.332). COM, Chole, and MEE also showed significant chronological changes in microbial profiles over time. The frequency of CNS increased markedly in COM and Chole (p = 0.029 and 0.028, respectively); however, S. pneumoniae infection decreased significantly in MEE (p = 0.016). Methicillin-resistant S. aureus (MRSA) demonstrated a constant trend (p = 0.564), whereas ciprofloxacin-resistant P. aeruginosa increased over time (p < 0.001). Microbial profiles have changed over a 20-year period. Increases in the frequency of coagulase-negative Staphylococcus (CNS) and bacterial resistance to ciprofloxacin, used widely in treating ear infections, are noteworthy.

While acute appendicitis is a common surgical problem, the simultaneous occurrence of appendicitis and an infected iliac artery pseudoaneurysm is exceedingly rare. We report the successful treatment of an infected right external iliac artery pseudo aneurysm in the 1setting of acute appendicitis. The patient is an 83-year-old male who presents with severe sepsis, right lower quadrant and right leg pain. Additional past medical history is significant for rectal cancer status post resection and radiation therapy in 1997. Computed tomography (CT) on admission revealed a right iliopsoas muscle abscess, an inflamed Appendix and a pseudo aneurysm arising from the right external iliac artery. After consultations by multiple specialties, the plan was to proceed with percutaneous drainage of the abscess, antibiotic therapy and subsequent repair of the pseudoaneurysm. CT guided drainage of the iliopsoas abscess was performed with return of hemorrhagic fluid. Due to the concern of contained pseudoaneurysm rupture, the patient was taken for expedited repair. Due to the patient's frailty and hostile abdomen, we performed embolization of the right external iliac artery pseudoaneurysm with Amplatzer I plugs (St. Jude Medical, St. Paul MN) and left common femoral to right superficial femoral bypass with cryopreserved cadaveric femoral vein. Following pseudoaneurysm exclusion, continued percutaneous drainage and antibiotic therapy, the patient has done well with no further evidence of infection. Repair of infected pseudo aneurysms can prove challenging. Ongoing infection, a hostile surgical abdomen and patient frailty further complicates the treatment of these patients. This case displays a minimally invasive approach to this rare but morbid condition. Copyright © 2017 The Author(s). Published by Elsevier Ltd.. All rights reserved.

During walking, muscles must perform positive work to replace the energy lost from the body at each step, even if the average speed is constant and the terrain level. Young children have immature and irregular walk, but little is known about the effect of this walking pattern on the muscular external work done. Our objective was to measure using force platforms and the method of Cavagna (J Appl Physiol 39:174-179, 1975) the amount of muscular external work done by 1-year-old-, 4-year-old children and adults during walking. We were interested to quantify the approximation made by measuring only the positive external work done and assuming it reflects the external work done. After having confirmed that young children were not able to walk at a constant average speed over a complete number of steps, we showed the effect of the selection of trials by measuring the external work done assuming the amount of positive work done is equal to the negative work done (supposing there is no acceleration or deceleration over a complete number of steps). We observed that even if young subjects were not able to walk at a constant lateral speed over a complete number of steps, the amount of work done to maintain the center of mass movements in the transversal plane is not more than 10% of the external positive work done. This observational study points out that the measurement of external work, a good summary indicator for the gait mechanics, may be interpreted precociously when the population studied walked irregularly.

Emerging Adults with Type 1 Diabetes during the First Year Post-High School: Perceptions of Parental Behaviors

2014-01-01

Among 182 emerging adults with type 1 diabetes (93% White and 57% female), changes during the year post-high school were examined in perceptions of diabetes-specific conflict with parents, parent-youth shared responsibility, parental tangible aid, and parental autonomy support, as well as the moderating effects of living situation, gender, years with diabetes, and glycemic control. A linear mixed effects model, controlling for baseline values, tested the changes in and relationships among these variables over time. Changes over time in parent-youth conflict were moderated by living independently of parents; autonomy support and shared responsibility were moderated by years with diabetes; and tangible aid was moderated by glycemic control. Future longitudinal research needs to examine whether changes in parental behaviors lead to positive or negative diabetes outcomes among these emerging adults with diabetes. PMID:25019036

Predicting renal graft failure by sCD30 levels and de novo HLA antibodies at 1year post-transplantation.

HLA antibodies and sCD30 levels were detected in the serum sampled from 620 renal graft recipients at 1 year post-transplantation, which were followed up for 5 years. Six-year graft and patient survivals were 81.6% and 91.0%. HLA antibodies were detected in 45 recipients (7.3%), of whom there were 14 cases with class I antibodies, 26 cases with class II, and 5 cases with both class I and II. Much more graft loss was record in recipients with HLA antibodies than those without antibodies (60% vs. 15.1%, p<0.001). Significantly higher sCD30 levels were recorded in recipients suffering graft loss than the others (73.9±48.8 U/mL vs. 37.3±14.6 U/mL, p<0.001). Compared with those with high sCD30 levels, recipients with low sCD30 levels (<50 U/mL) had much better 6-year graft survival (92.4% vs. 46.6%, p<0.001). Further statistical analysis showed that detrimental effect of de novo HLA antibodies and high sCD30 on graft survival was not only independent but also additive. Therefore, post-transplantation monitoring of HLA antibodies and sCD30 levels is necessary and recipients with elevated sCD30 level and/or de novo HLA antibody should be paid more attention in order to achieve better graft survival.

This study investigates the role of external debt stock in Turkey, which has suffered from heavy (external and domestic) debt stock for many years. Annual data from 1960 to 2013 was analyzed using time series analysis in order to study this. The results confirm the validity of the conventional environmental Kuznets curve (EKC) in the case of Turkey. However, this study also found that Turkey's external debt stock did not influence the Turkish economy's long-term EKC behavior. Fortunately, the results suggest that there are important interactions among external debt stock, CO 2 emissions, energy consumption, and real income; that is, changes in external debt volume precede changes in these aggregates' volumes.

Objective This study aims to explore the short-term and long-term prevalence and effects of post-traumatic stress disorder (PTSD) among victims of cluster munitions. Design and setting A prospective 10-year longitudinal study that took place in Lebanon. Participants Two-hundred-and-forty-four Lebanese civilian victims of submunition blasts, who were injured in 2006 and were over 18 years old, were interviewed. Included were participants who had been diagnosed with PTSD according to the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5) and the PTSD Checklist - Civilian Version in 2006. Interviewees were present for the 10-year follow-up. Main outcome measures PTSD prevalence rates of participants in 2006 and 2016 were compared. Analysis of the demographical data pertaining to the association of long-term PTSD with other variables was performed. p Values <0.05 were considered statistically significant for all analyses (95% CI). Results All the 244 civilians injured by cluster munitions in 2006 responded, and were present for long-term follow-up in 2016. The prevalence of PTSD decreased significantly from 98% to 43% after 10 years (p<0.001). A lower long-term prevalence was significantly associated with male sex (p<0.001), family support (p<0.001) and religion (p<0.001). Hospitalisation (p=0.005) and severe functional impairment (p<0.001) post-trauma were significantly associated with increased prevalence of long-term PTSD. Symptoms of negative cognition and mood were more common in the long run. In addition, job instability was the most frequent socioeconomic repercussion among the participants (88%). Conclusions Psychological symptoms, especially PTSD, remain high in war-affected populations many years after the war; this is particularly evident for Lebanese civilians who were victimised by cluster munitions. Screening programmes and psychological interventions need to be implemented in vulnerable populations exposed to war traumas

The most common type of hydrocephalus in developing countries is post infective hydrocephalus. Infected cerebrospinal fluid (CSF) however cannot be shunted for the reason that it will block the chamber of the ventriculo-peritoneal (VP) shunt due to its high protein content. In centers where standard external ventricular drain (EVD) sets are not available, improvised feeding tube can be used. The main focus of this study is to encourage the use of improvised feeding tube catheters for EVD when standard sets are not available to improve patients' survival. This was a prospective study. Consecutive patients with hydrocephalus that cannot be shunted immediately for high chances of shunt failure or signs of increasing intracranial pressure were recruited into the study. Other inclusion criteria were preoperative brain tumor with possibility of blocked CSF pathway and massive intraventricular hemorrhage necessitating ventricular drainage as a salvage procedure. Standard EVD set is not readily available and too expensive for most of the parents to afford. Improvised feeding tube is used to drain/divert CSF using the standard documented procedure for EVD insertion. Outcome is measured and recorded. A total of 28 patients were recruited into the study over a time frame of 2 years. There were 19 (67.9%) male and 9 (32.1%) females with a ratio of about 2:1. Age ranges varied from as low as 7 days to 66 years. The median age of the study sample was 6.5 months while the mean was 173.8 months. Duration of EVD varied from 2 days to 11 days with a median of 7 while the average was 6 days. Eventual outcome following the procedure of EVD showed that 19 (67.9%) survived and were discharged either to go home or to have VP shunt afterwards while 8 (28.6%) of the patients died. External ventricular drain can and should be done when it is necessary. Potential mortalities could be reduced by the improvised drainage using a standard feeding tube as described.

Adolescent insecure attachment as a predictor of maladaptive coping and externalizing behaviors in emerging adulthood

2014-01-01

This study investigated whether insecure adolescent attachment organization (i.e., preoccupied and dismissing) longitudinally predicted self- and peer-reported externalizing behavior in emerging adulthood. Secondarily, maladaptive coping strategies were examined for their potential role in mediating the relationship between insecure attachment and future externalizing behaviors. Target participants (N = 184) were given the Adult Attachment Interview (AAI) at age 14 and re-interviewed seven and eight years later with their closest peer. Qualities of both preoccupied and dismissing attachment organization predicted self-reported externalizing behaviors in emerging adulthood eight years later, but only preoccupation was predictive of close-peer reports of emerging adult externalizing behavior. Maladaptive coping strategies only mediated the relationship between a dismissing stance toward attachment and future self-reported externalizing behaviors. Understanding the role of coping and emotional regulation in attachment may help us to understand the unique aspects of both dismissing and preoccupied stances toward attachment. PMID:24995478

Background and purpose In unstable distal radial fractures that are impossible to reduce or to maintain in reduced position, the treatment of choice is operation. The type of operation and the choice of implant, however, is a matter of discussion. Our aim was to investigate whether open reduction and internal fixation would produce a better result than traditional external fixation. Methods 50 patients with an unstable or comminute distal radius fracture were randomized to either closed reduction and bridging external fixation, or open reduction and internal fixation using the TriMed system. The primary outcome parameter was grip strength, but the patients were followed for 1 year with objective clinical assessment, subjective outcome using DASH, and radiographic examination. Results At 1 year postoperatively, grip strength was 90% (SD 16) of the uninjured side in the internal fixation group and 78% (17) in the external fixation group. Pronation/supination was 150° (15) in the internal fixation group and 136° (20) in the external fixation group at 1 year. There were no differences in DASH scores or in radiographic parameters. 5 patients in the external fixation group were reoperated due to malunion, as compared to 1 in the internal fixation group. 7 other cases were classified as radiographic malunion: 5 in the external fixation group and 2 in the internal fixation group. Interpretation Internal fixation gave better grip strength and a better range of motion at 1 year, and tended to have less malunions than external fixation. No difference could be found regarding subjective outcome. PMID:19857180

The relations of parenting and temperament (effortful control and anger/frustration) to children's externalizing problems were examined in a 3.8-year longitudinal study of 425 native Chinese children (6-9 years) from Beijing. Children's experience of negative life events and coping efficacy were examined as mediators in the parenting- and temperament-externalizing relations. Parents reported on their own parenting. Parents and teachers rated temperament. Children reported on negative life events and coping efficacy. Parents, teachers, children, or peers rated children's externalizing problems. Authoritative and authoritarian parenting and anger/frustration uniquely predicted externalizing problems. The relation between authoritarian parenting and externalizing was mediated by children's coping efficacy and negative school events. The results suggest there is some cross-cultural universality in the developmental pathways for externalizing problems.

Adolescents who like each other may become more similar to each other with regard to internalizing and externalizing problems, though it is not yet clear which social mechanisms explain these similarities. In this longitudinal study, we analyzed four mechanisms that may explain similarity in adolescent peer networks with regard to externalizing and internalizing problems: selection, socialization, avoidance and withdrawal. At three moments during one school-year, we asked 542 adolescents (8th grade, M-age = 13.3 years, 51 % female) to report who they liked in their classroom, and their own internalizing and externalizing problems. Adolescents tend to prefer peers who have similar externalizing problem scores, but no significant selection effect was found for internalizing problems. Adolescents who share the same group of friends socialize each other and then become more similar with respect to externalizing problems, but not with respect to internalizing problems. We found no significant effects for avoidance or withdrawal. Adolescents may choose to belong to a peer group that is similar to them in terms of externalizing problem behaviors, and through peer group socialization (e.g., enticing, modelling, mimicking, and peer pressure) become more similar to that group over time.

Sleep quality is associated with different aspects of psychopathology, but relatively little research has examined links between sleep quality and externalizing behaviors or callous-unemotional traits. We examined: (1) whether an association exists between sleep quality and externalizing behaviors; (2) whether anxiety mediates this association; (3) whether callous-unemotional traits are associated with sleep quality. Data from two studies were used. Study 1 involved 1556 participants of the G1219 study aged 18-27 years (62% female). Questionnaire measures assessed sleep quality, anxiety, externalizing behaviors, and callous-unemotional traits. Study 2 involved 338 participants aged 18-66 years (65% female). Questionnaires measured sleep quality, externalizing behaviors, and callous-unemotional traits. In order to assess objective sleep quality, actigraphic data were also recorded for a week from a subsample of study 2 participants (n = 43). In study 1, poorer sleep quality was associated with greater externalizing behaviors. This association was partially mediated by anxiety and moderated by levels of callous-unemotional traits. There was no significant relationship between sleep quality and callous-unemotional traits. In study 2, poorer sleep quality, as assessed via self-reported but not objective measures, was associated with higher levels of externalizing behaviors. Furthermore, in study 2, better sleep quality (indicated in both questionnaires and actigraphy measures: lower mean activity, and greater sleep efficiency) was associated with higher levels of callous-unemotional traits. Self-reports of poorer sleep quality are associated with externalizing behaviors, and this association is partially mediated by anxiety. Callous-unemotional traits are not associated with poor sleep and may even be related to better sleep quality. This is an exceptional finding given that poor sleep quality appears to be a characteristic of most psychopathology. © Sleep Research

Objectives Long-term magnetic resonance angiography (MRA) follow-up studies regarding cryptogenic nonperimesencephalic subarachnoid hemorrhage (nSAH) are scarce. This single-centre study identified all patients with angiographically verified cryptogenic nSAH from 1998 to 2007: The two main objectives were to prospectively assess the incidence of de novo aneurysm with 3.0-MRI years after cryptogenic nSAH in patients without evidence for further hemorrhage, and retrospectively assess patient demographics and outcome. Methods From prospectively maintained report databases all patients with angiographically verified cryptogenic nSAH were identified. 21 of 29 patients received high-resolution 3T-MRI including time-of-flight and contrast-enhanced angiography, 10.2 ± 2.8 years after cryptogenic nSAH. MRA follow-up imaging was compared with initial digital subtraction angiography (DSA) and CT/MRA. Post-hemorrhage images were related to current MRI with reference to persistent lesions resulting from delayed cerebral ischemia (DCI) and post-hemorrhagic siderosis. Patient-based objectives were retrospectively abstracted from clinical databases. Results 29 patients were identified with cryptogenic nSAH, 17 (59%) were male. Mean age at time of hemorrhage was 52.9 ± 14.4 years (range 4 – 74 years). 21 persons were available for long-term follow-up. In these, there were 213.5 person years of MRI-follow-up. No de novo aneurysm was detected. Mean modified Rankin Scale (mRS) during discharge was 1.28. Post-hemorrhage radiographic vasospasm was found in three patients (10.3%); DCI-related lesions occurred in one patient (3.4%). Five patients (17.2%) needed temporary external ventricular drainage; long-term CSF shunt dependency was necessary only in one patient (3.4%). Initial DSA retrospectively showed a 2 x 2 mm aneurysm of the right distal ICA in one patient, which remained stable. Post-hemorrhage siderosis was detected 8.1 years after the initial bleeding in one patient (4

External Validation of a Decision Tool To Guide Post-Operative Management of Patients with Secondary Peritonitis.

Atema, Jasper J; Ram, Kim; Schultz, Marcus J; Boermeester, Marja A

Timely identification of patients in need of an intervention for abdominal sepsis after initial surgical management of secondary peritonitis is vital but complex. The aim of this study was to validate a decision tool for this purpose and to evaluate its potential to guide post-operative management. A prospective cohort study was conducted on consecutive adult patients undergoing surgery for secondary peritonitis in a single hospital. Assessments using the decision tool, based on one intra-operative and five post-operative variables, were performed on the second and third post-operative days and when the patients' clinical status deteriorated. Scores were compared with the clinical reference standard of persistent sepsis based on the clinical course or findings at imaging or surgery. Additionally, the potential of the decision tool to guide management in terms of diagnostic imaging in three previously defined score categories (low, intermediate, and high) was evaluated. A total of 161 assessments were performed in 69 patients. The majority of cases of secondary peritonitis (68%) were caused by perforation of the gastrointestinal tract. Post-operative persistent sepsis occurred in 28 patients. The discriminative capacity of the decision tool score was fair (area under the curve of the receiver operating characteristic = 0.79). The incidence rate differed significantly between the three score categories (p < 0.001). The negative predictive value of a decision tool score categorized as low probability was 89% (95% confidence interval [CI] 82-94) and 65% (95% CI 47-79) for an intermediate score. Diagnostic imaging was performed more frequently when there was an intermediate score than when the score was categorized as low (46% vs. 24%; p < 0.001). In patients operated on for secondary peritonitis, the decision tool score predicts with fair accuracy whether persistent sepsis is present.

Anterior cruciate ligament injury about 20 years post-treatment: A kinematic analysis of one-leg hop.

Reduced dynamic knee stability, often evaluated with one-leg hops (OLHs), is reported after anterior cruciate ligament (ACL) injury. This may lead to long-standing altered movement patterns, which are less investigated. 3D kinematics during OLH were explored in 70 persons 23 ± 2 years after ACL injury; 33 were treated with physiotherapy in combination with ACL reconstruction (ACL(R)) and 37 with physiotherapy alone (ACL(PT)). Comparisons were made to 33 matched controls. We analyzed (a) maximal knee joint angles and range of motion (flexion, abduction, rotation); (b) medio-lateral position of the center of mass (COM) in relation to knee and ankle joint centers, during take-off and landing phases. Unlike controls, ACL-injured displayed leg asymmetries: less knee flexion and less internal rotation at take-off and landing and more lateral COM related to knee and ankle joint of the injured leg at landing. Compared to controls, ACL(R) had larger external rotation of the injured leg at landing. ACL(PT) showed less knee flexion and larger external rotation at take-off and landing, and larger knee abduction at Landing. COM was more medial in relation to the knee at take-off and less laterally placed relative to the ankle at landing. ACL injury results in long-term kinematic alterations during OLH, which are less evident for ACL(R). © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Background: In our modern world, the way of life in nutritional and activity behaviour has changed. As a consequence, parallel trends of an epidemic of overweight and a decline in external skeletal robusticity are observed in children and adolescents. Aim: We aim to develop reference centiles for external skeletal robusticity of European girls and boys aged 0 to 18 years using the Frame Index as an indicator and identify population specific age-related patterns. Methods: We analysed cross-sectional & longitudinal data on body height and elbow breadth of boys and girls from Europe (0-18 years, n = 41.679), India (7-18 years, n = 3.297) and South Africa (3-18 years, n = 4.346). As an indicator of external skeletal robusticity Frame Index after Frisancho (1990) was used. We developed centiles for boys and girls using the LMS-method and its extension. Results: Boys have greater external skeletal robusticity than girls. Whereas in girls Frame Index decreases continuously during growth, an increase of Frame Index from 12 to 16 years in European boys can be observed. Indian and South African boys are almost similar in Frame Index to European boys. In girls, the pattern is slightly different. Whereas South African girls are similar to European girls, Indian girls show a lesser external skeletal robusticity. Conclusion: Accurate references for external skeletal robusticity are needed to evaluate if skeletal development is adequate per age. They should be used to monitor effects of changes in way of life and physical activity levels in children and adolescents to avoid negative health outcomes like osteoporosis and arthrosis.

Post-traumatic osteoarthritis (PTOA) commonly affects the knee joint. Although the risk of PTOA substantially increases post-joint injury, there is little research examining PTOA outcomes early in the period between joint injury and disease onset. Improved understanding of this interval would inform secondary prevention strategies aimed at preventing and/or delaying PTOA progression. This study examines the association between sport-related knee injury and outcomes related to development of PTOA, 3-10 years post-injury. This preliminary analysis of the first year of a historical cohort study includes 100 (15-26 years) individuals. Fifty with a sport-related intra-articular knee injury sustained 3-10 years previously and 50 uninjured age, sex and sport matched controls. The primary outcome was the 'Symptoms' sub-scale of the Knee Osteoarthritis and Injury Outcome Score (KOOS). Secondary outcomes included; the remaining KOOS subscales, body mass index (BMI), hip abductor/adductor and knee extensor/flexor strength, estimated aerobic capacity (VO2max) and performance scores on three dynamic balance tests. Descriptive statistics (mean within-pair difference; 95% Confidence interval (CI) and conditional odds ratio (OR, 95% CI; BMI) were used to compare study groups.

Transaction costs, externalities and information technology in health care.

PubMed

Ferguson, B; Keen, J

1996-01-01

This paper discusses some of the economic issues which underpin the rationale for investment in information and communications technologies (ICTs). Information imperfections lead to significant transaction costs (search, negotiating and monitoring) which in turn confer a negative externality on parties involved in exchange. This divergence in private and social costs leads to a degree of resource misallocation (efficiency loss) which, uncorrected, results in a sub-optimal outcome. Traditional solutions to this problem are to rely upon direct government action to reduce the costs of transacting between market agents, or to employ tax/subsidy measures and other legislative action to achieve the desired market outcome. Three key policy questions are raised in the context of the NHS purchaser/provider relationship. Firstly, what is the optimum level of transaction costs; secondly, can ICTs assist in lowering the level of transaction costs to the optimum level; thirdly, who should bear the investment cost in reducing the level of transaction costs? The issue of property rights in different information systems is discussed and raises interesting policy questions about how much investment should be undertaken centrally rather than devolved to a more local level. In some ways this economic framework offers a post hoc justification of why different ICT systems have been introduced at various levels of the NHS. Essentially this reduces to the problem of externalities: providing good information confers a positive externality: not providing relevant, timely and accurate information confers a negative externality, by increasing further the level of transaction costs. The crucial role which ICT systems can play lies in attempting to reduce the level of transaction costs and driving the market towards what Dahlman has described as the transaction-cost-constrained equilibrium.

The interplay of externalizing problems and physical and inductive discipline during childhood.

Children who are physically disciplined are at elevated risk for externalizing problems. Conversely, maternal reasoning and reminding of rules, or inductive discipline, is associated with fewer child externalizing problems. Few studies have simultaneously examined bidirectional associations between these forms of discipline and child adjustment using cross-informant, multimethod data. We hypothesized that less inductive and more physical discipline would predict more externalizing problems, children would have evocative effects on parenting, and high levels of either form of discipline would predict low levels of the other. In a study of 241 children-spanning ages 3, 5.5, and 10-structural equation modeling indicated that 3-year-olds with higher teacher ratings of externalizing problems received higher mother ratings of physical discipline at age 5.5. Mothers endorsing more inductive discipline at child age 3 reported less physical discipline and had children with fewer externalizing problems at age 5.5. Negative bidirectional associations emerged between physical and inductive discipline from ages 5.5 to 10. Findings suggested children's externalizing problems elicited physical discipline, and maternal inductive discipline might help prevent externalizing problems and physical discipline.

This article presents outcome data of the implementation of three group cognitive-behavioral therapy (GCBT) interventions for children with externalizing behavior problems, anxiety, and depression. School counselors and graduate students co-led the groups in two low-income urban schools. Data were analyzed to assess pre-treatment to post-treatment changes in diagnostic severity level. Results of the exploratory study indicated that all three GCBT protocols were effective at reducing diagnostic severity level for children who had a primary diagnosis of an externalizing disorder, anxiety disorder, or depressive disorder at the clinical or intermediate (at-risk) level. All three GCBT protocols were implemented with relatively high levels of fidelity. Data on the effectiveness of the interventions for reducing diagnostic severity level for externalizing and internalizing spectrum disorders and for specific disorders are presented. A discussion of implementation of mental health evidence-based interventions in urban schools is provided. © The Author(s) 2016.

To investigate the associated factors and change trajectories of quality of life (QoL), global outcome, and post-concussion symptoms (PCS) over the first year following mild traumatic brain injury (mTBI). This was a prospective longitudinal study of 100 participants with mTBI from neurosurgical outpatient departments in Chiayi County District Hospitals in Taiwan. The checklist of post-concussion syndromes (CPCS) was used to assess PCS at enrollment and at 1, 3, and 12 months after mTBI; the glasgow outcome scale extended (GOSE), the quality of life after brain injured (QOLIBRI), Chinese version, and the Short Form 36 Health Survey (SF-36), Taiwan version, were used to assess mTBI global outcome and QoL at 1, 3, and 12 months after mTBI. Latent class growth models (LCGMs) indicated the change trajectories of QOLIBRI, PCS SF-36, MCS SF-36, GOSE, and PCS. Classes of trajectory were associated with age ≥40 years, unemployment at 1 month after injury, and educational level ≤12 years. Univariate analysis revealed that employment status at 1 month post-injury was correlated with the trajectories of QOLIBRI, PCS SF-36, MCS SF-36, and GOSE, but not PCS. Employment status was the most crucial associated factor for QoL in individuals with mTBI at the 1-year follow-up. Future studies should explore the benefits of employment on QoL of individuals with mTBI.

In a randomized controlled trial, the Observational Randomized Controlled Trial of Childhood Differential Susceptibility (ORCHIDS study), we tested whether observed parental affect and observed and reported parenting behavior are mechanisms of change underlying the effects of the behavioral parent training program the Incredible Years (IY). Furthermore, we tested whether some children are more susceptible to these change mechanisms because of their temperamental negative affectivity and/or serotonin transporter linked polymorphic region (5-HTTLPR) genotype. Participants were 387 Dutch children between 4 and 8 years of age (M age = 6.31, SD = 1.33; 55.3% boys) and their parents. Results showed that although IY was successful in improving parenting behavior and increasing parental positive affect, these effects did not explain the significant decreases in child externalizing problems. We therefore found no evidence for changes in parenting behavior or parental affect being the putative mechanisms of IY effectiveness. Furthermore, intervention effects on child externalizing behavior were not moderated by child negative affectivity or 5-HTTLPR genotype. However, child 5-HTTLPR genotype did moderate intervention effects on negative parenting behavior. This suggests that in research on behavioral parent training programs, "what works for which parents" might also be an important question.

Background There is evidence both that parental monitoring is an environmental influence serving to diminish adolescent externalizing problems and that this association may be driven by adolescents’ characteristics via genetic and/or environmental mechanisms, such that adolescents with fewer problems tell their parents more, and therefore appear to be better monitored. Without information on how parents’ and children’s genes and environments influence correlated parent and child behaviors, it is impossible to clarify the mechanisms underlying this association. Method The present study used the Extended Children of Twins model to distinguish types of gene-environment correlation and direct environmental effects underlying associations between parental knowledge and adolescent (age 11-22 years) externalizing behavior with a Swedish sample of 909 twin parents and their adolescent offspring and a US-based sample of 405 White adolescent siblings and their parents. Results Results suggest that more parental knowledge is associated with less adolescent externalizing via a direct environmental influence independent of any genetic influences. There was no evidence of a child-driven explanation of the association between parental knowledge and adolescent externalizing problems. Conclusions In this sample of adolescents, parental knowledge exerted an environmental influence on adolescent externalizing after accounting for genetic influences of parents and adolescents. Because the association between parenting and child development originates in the parent, treatment for adolescent externalizing must not only include parents but should focus on altering their parental style. Thus, findings suggest that teaching parents better knowledge-related monitoring strategies is likely to help reduce externalizing problems in adolescents. PMID:24975929

Patients with operated cleft lip and palate present with a problem of midface hypoplasia, and such patients have been traditionally treated with orthognathic surgery. Such a procedure has its own limitations of relapse and hence a newer modality of distraction osteogenesis with histiogenesis can be chosen to overcome such limitations for midfacial advancement. The purpose of this study is to evaluate an alternative technique and its postoperative stability in maxillary distraction osteogenesis in patients of cleft lip and cleft palate using a rigid external device (RED). Nine patients with midface bone stock deficiency were selected for maxillary advancement. At the first surgery under general anesthesia, after Le Fort I osteotomy, RED system was used with the alternative technique. After distraction, evaluation was done for ease of the procedure, stability, and complications. Lateral cephalograms were evaluated at 3 stages: T1, pre-distraction; T2, post-distraction; and T3, 1 year post-distraction. A mean 13.4-mm midface advancement was shown with bone formation at the pterygomaxillary region without losing the vector and having a standby mode in case the wire broke during distraction The results were stable even at 1 year of follow-up. Maxillary position improved in relation to the cranial base. This study showed that the RED was versatile in midface advancement.

To evaluate the availability and accessibility of community automated external defibrillators in a territory in Hong Kong. Cross-sectional study. Two public hospitals in New Territories West Cluster in Hong Kong. Information about the locations of community automated external defibrillators was obtained from automated external defibrillator suppliers and through community search. Data on locations of out-of-hospital cardiac arrests from August 2010 to September 2013 were obtained from the local cardiac arrest registry of the emergency departments of two hospitals. Sites of both automated external defibrillators and out-of-hospital cardiac arrests were geographically coded and mapped. The number of out-of-hospital cardiac arrests within 100 m of automated external defibrillators per year and the proportion of out-of-hospital cardiac arrests with accessible automated external defibrillators (100 m) were calculated. The number of community automated external defibrillators per 10,000 population and public access defibrillation rate were also calculated and compared with those in other countries. There were a total of 207 community automated external defibrillators in the territory. The number of automated external defibrillators per 10,000 population was 1.942. All facilities with automated external defibrillators in this territory had more than 0.2 out-of-hospital cardiac arrests per automated external defibrillator per year within 100 m. Among all out-of-hospital cardiac arrests, 25.2% could have an automated external defibrillator reachable within 100 m. The public access defibrillation rate was 0.168%. The number and accessibility of community automated external defibrillators in this territory are comparable to those in other developed countries. The placement site of community automated external defibrillators is cost-effective. However, the public access defibrillation rate is low.

First branchial cleft abnormalities are rare. They may involve the external auditory canal and middle ear. We describe a 6-year-old girl with congenital external auditory canal atresia, microtia, and cholesteatoma of mastoid and middle ear in addition to the first branchial cleft abnormalities. Clinical features of the patient are briefly described and the embryological relationship between first branchial cleft anomaly and external auditory canal atresia is discussed. The surgical management of these lesions may be performed, both the complete excision of the sinus and reconstructive otologic surgery.

External pancreatic secretion after bombesin infusion in man.

The effect of bombesin on external pancreatic secretion was studied in seven healthy volunteers and intwo patients with a two-thirds gastrectomy and a pancreatic fistula. After bombesin infusion (15 ng/kg/min), gastrin levels were significantly raised in all volunteers, but remained at basal levels in the gastrectomized patients. Bombesin was effective in stimulating pancreatic secretion in all patients. The volume of secretion increased tow-fold when compared with basal volume. Amylase and trypsin concentrations and outputs in the duodenal juice were greatly agumented (amylase concentration: basal, 70 dye U/ml; post-bombesin, 620 dye U/ml. Amylase output: basal, 1000 dye U/15 min; post-bombesin, 15,800 dye U/15 min). Secretin, when administered in conjunction with bombesin, partially inhibited its secretory effect. Bicarbonate secretion was slightly stimulated by bombesin, but at a very low level. A similar pattern of results was obtained in the two gastrectomized patients. In man, bombesin exerts an effect on pancreatic secretion that mimics the effect of CCK-PZ, thus confirming the results obtained in the experimental animal. Gastrin does not play a fundamental role in this phenomenon.

The purpose of this study was to evaluate the prevalence of depressive symptoms in peri- and post-menopausal Taiwanese women, and to investigate the relation between depressive symptoms and demographic variables, chronic disease status, health habits, stress management, menopausal symptoms, and attitudes toward menopause and aging. Cross-sectional study, using a purposive sample of 566 women between 45 and 60 years of age from a medical center and residential community in Southern Taiwan. Demographic and health habits questionnaire, Women's Health Initiative Symptom Scale, Attitudes Toward Menopause and Aging Scale, and Center for Epidemiological Studies-Depression Scale (CES-D). The prevalence of depressive symptoms (CES-D score≥16) was 38.7% in peri- and post-menopausal Taiwanese women. Bivariate correlations and analyses of variance indicated that higher CES-D scores were related to lower family income, younger age, smoking for a greater number of years, consuming more alcohol, having multiple chronic diseases, not exercising regularly, consulting with a specialist for stress management, having more severe menopausal symptoms, and more negative attitudes toward menopause and aging. A stepwise multiple regression analysis indicated that the key predictors, accounting for 33.7% of the variance, were menopausal symptoms, attitudes toward menopause and aging, family income, and chronic disease status. Results highlight the importance of considering psychosocial factors, life style, and chronic disease management in providing health guidance for peri- and post-menopausal women to enhance their quality of life and reduce the risk of depressive symptoms.

Contemporary post surgical management of differentiated thyroid carcinoma.

PubMed

Tala, H; Tuttle, R M

2010-08-01

Risk assessment is the cornerstone of contemporary management of thyroid cancer. Following thyroid surgery, an initial risk assessment of recurrence and disease-specific mortality is made using important intra-operative findings, histologic characteristics of the tumor, molecular profile of the tumor, post-operative serum thyroglobulin and any available cross-sectional imaging studies. This initial risk assessment is used to guide recommendations regarding the need for remnant ablation, external beam irradiation, systemic therapy, degree of TSH suppression, and follow-up disease detection strategy over the first 2 years after initial therapy. While this initial risk stratification provides valuable information, it is a static representation of the patient in the first few weeks post-operatively that does not change over time. Depending on how the patient responds to our initial therapies, the risk of recurrence and death may change significantly during follow-up. In order to account for differences in response to therapy in individual patients and to incorporate the impact of treatment on our initial risk estimates, we recommend a re-stratification of risk at the 2-year point of follow-up. This re-stratification provides an updated risk estimate that can be used to guide ongoing management recommendations including the frequency and intensity of follow-up, degree of ongoing TSH suppression, and need for additional therapies. Ongoing management recommendations must be tailored to realistic, evolving risk estimates that are actively updated during follow-up. By individualizing therapy on the basis of initial and ongoing risk assessments, we can maximize the beneficial effects of aggressive therapy in patients with thyroid cancer who are likely to benefit from it, while minimizing potential complications and side effects in low-risk patients destined to have a full healthy and productive life after minimal therapeutic intervention.

Human immunodeficiency virus type 1 (HIV-1), hepatitis B virus (HBV) and hepatitis C virus (HCV) viral load determinations are among the most relevant markers for the follow up of patients infected with these viruses. External quality control tools are crucial to ensure the accuracy of results obtained by microbiology laboratories. This article summarizes the results obtained from the 2014 SEIMC (Spanish Society of Infectious Diseases and Clinical Microbiology) External Quality Control Programme for HIV-1, HCV, and HBV viral loads. In the HIV-1 program, a total of 5 standards were sent. One standard consisted in seronegative human plasma, while the remaining 4 contained plasma from 3 different viremic patients, in the range of 2-5 log10 copies/mL; 2 of these standards were identical aiming to determine repeatability. A significant proportion of the laboratories (30.8% on average) obtained values out of the accepted range (mean ± 0.25 log10 copies/mL), depending on the standard and on the method used for quantification. Repeatability was excellent, with up to 95.8% of laboratories reporting results within the limits (Δ < 0.5 log10 copies/mL). The HBV and HCV program consisted of 2 standards with different viral load contents. Most of the participants, 83.7% in the case of HCV and 87.9% in the HBV, obtained all the results within the accepted range (mean ± 1.96 standard deviations log10 IU/mL). Data from this analysis reinforce the utility of proficiency programmes to ensure the quality of the results obtained by a particular laboratory, as well as the importance of the post-analytical phase on the overall quality. Due to the remarkable interlaboratory variability, it is advisable to use the same method and the same laboratory for patient follow up. Copyright © 2016 Elsevier España, S.L.U. All rights reserved.

Wildfires are a natural phenomenon in regions with a Mediterranean-type climate. However, their present-day widespread occurrence in southern Europe is unprecedented and strongly reflects human activity such as ignition, land-use changes, land abandonment and introduction of highly flammable plantations. Besides wildfires, post-fire management practices such as plowing, terracing, clearcutting and logging should also be considered, since their occurrence is getting increasingly common. And, in a long-term period these practices seem to be executed intercalated with repeated fire occurrences in the same site, sharing the impacts together with fire in an escalated degradational effect. In this sense, the work presented here concerns four years of runoff and erosion data at microplot scale after the wildfire, comparing different land management practices that occurred before the fire. Preliminary results indicate that in four years of monitoring, runoff is constantly higher in plowed sites than in the unplowed ones, with the exception of the first year. Regarding soil losses the plowed plots present always higher sediment rates than the unplowed ones. The comparison between two unplowed sites with different land uses, indicate higher runoff and erosion risk for pine comparatively to the eucalypt ones, however the reduced soil depth in the first can have an important role in these differences. Following these facts, the aim of the present work is to answer the following research questions: i) Do these four years of observations fit with the window of disturbance model presented by Prosser and Williams (1998). or the alternative version by Wittenberg and Inbar (2009)?; ii) Does pre-fire disturbances (wildfire, land use changes and land management practices) still have repercussions after wildfire?; In what sense does four years of intensive monitoring provides that one year couldn't provide?

Attenuated pediatric electrode pads for automated external defibrillator use in children.

Atkins, Dianne L; Jorgenson, Dawn B

2005-07-01

This post-market, observational study is intended to evaluate reported uses of pediatric pads that reduce the energy delivered by some adult automated external defibrillators (AEDs) so that they may be used with pediatric patients. Users of the pediatric pads were asked to report any use of the pads, even if no shock was delivered and to provide detailed information about the event, caregiver and the patient. Reports of the use of pediatric pads have been received and confirmed for 27 patients, age range 0 days to 23 years, median 2 years. Ventricular fibrillation (VF) was reported in eight cases, age range 4.5 months to 10 years, median 3 years. Shocks were delivered to all VF patients, the average shock number was 1.9, range 1-4. All patients had termination of VF, were admitted to the hospital and five survived to hospital discharge. Non-shockable rhythms were reported in 16 patients, and the AED appropriately did not advise a shock. Eleven of these patients had asystole or PEA as their initial rhythm and did not survive to hospital discharge. One report contained no additional information other than that the patient did not survive, and in two other reports, the pads were not applied to patients. Voluntary reports of the use of attenuated pediatric defibrillation pads indicate the devices performed appropriately. All eight VF patients had termination of VF and five survived to hospital discharge. These data support the rapid deployment of AEDs for young children as well as adolescents and adults. Since the pediatric pads are available and deliver an appropriate dose for children, their use should be strongly encouraged.

Effects of Prenatal Cocaine Exposure on Early Sexual Behavior: Gender Difference in Externalizing Behavior as a Mediator

2015-01-01

Background Prenatal cocaine exposure (PCE) is associated with increased risk for externalizing behavior problems; childhood externalizing behavior problems are linked with subsequent early sexual behavior. The present study examined the effects of PCE on early sexual initiation (sexual intercourse prior to age 15) and whether externalizing behavior in preadolescence mediated the relationship. Methods Three hundred fifty-four (180 PCE and 174 non-cocaine exposed; 192 girls, 142 boys), primarily African-American, low socioeconomic status, 15-year old adolescents participated in a prospective longitudinal study. Adolescents’ sexual behavior was assessed at 15 years using the Youth Risk Behavior Surveillance System. Externalizing behavior was assessed at 12 years using the Youth Self-Report. Results Logistic regression models indicated that adolescents with PCE (n=69, 38%) were 2.2 times more likely (95% CI= 1.2 – 4.1, p < .01) to engage in early sexual intercourse than non-exposed peers (n=49, 28%) controlling for covariates. This relationship was fully mediated by self-reported externalizing behavior in girls but not in boys, suggesting childhood externalizing behavior as a gender moderated mediator. Blood lead level during preschool years was also related to a greater likelihood of early sexual intercourse (OR=2.6, 95% CI=1.4 – 4.7, p < .002). Greater parental monitoring decreased the likelihood of early sexual intercourse, while violence exposure increased the risk. Conclusions PCE is related to early sexual intercourse, and externalizing behavior problems mediate PCE effects in female adolescents. Interventions targeting externalizing behavior may reduce early sexual initiation and thereby reduce HIV risk behaviors and early, unplanned pregnancy in girls with PCE. PMID:26088698

Dysfunction in the prefrontal cortex, amygdala, and hippocampus is believed to underlie the development of much psychopathology. However, to date only limited longitudinal data relate early behavior with neural structure later in life. Our objective was to examine the relationship of early life externalizing behavior with adolescent brain structure. We report here the first longitudinal study linking externalizing behavior during preschool to brain structure during adolescence. We examined the relationship of preschool externalizing behavior with amygdala, hippocampus, and prefrontal cortex volumes at age 15 years in a community sample of 76 adolescents followed longitudinally since their mothers’ pregnancy. A significant gender by externalizing behavior interaction revealed that males—but not females—with greater early childhood externalizing behavior had smaller amygdala volumes at adolescence (t = 2.33, p = .023). No significant results were found for the hippocampus or the prefrontal cortex. Greater early externalizing behavior also related to smaller volume of a cluster including the angular gyrus and tempoparietal junction across genders. Results were not attributable to the impact of preschool anxiety, preschool maternal stress, school-age internalizing or externalizing behaviors, or adolescent substance use. These findings demonstrate a novel, gender-specific relationship between early-childhood externalizing behavior and adolescent amygdala volume, as well as a cross-gender result for the angular gyrus and tempoparietal junction.

Kendler, Kenneth S.; Myers, John M.; Keyes, Corey L. M.

2012-01-01

To determine the relationship between the genetic and environmental risk factors for externalizing psychopathology and mental wellbeing, we examined detailed measures of emotional, social and psychological wellbeing, and a history of alcohol-related problems and smoking behavior in the last year in 1,386 individual twins from same-sex pairs from the MIDUS national US sample assessed in 1995. Cholesky decomposition analyses were performed with the Mx program. The best fit model contained one highly heritable common externalizing psychopathology factor for both substance use/abuse measures, and one strongly heritable common factor for the three wellbeing measures. Genetic and environmental risk factors for externalizing psychopathology were both negatively associated with levels of mental wellbeing and accounted for, respectively, 7% and 21% of its genetic and environmental influences. Adding internalizing psychopathology assessed in the last year to the model, genetic risk factors unique for externalizing psychopathology were now positively related to levels of mental wellbeing, although accounting for only 5% of the genetic variance. Environmental risk factors unique to externalizing psychopathology continued to be negatively associated with mental wellbeing, accounting for 26% of the environmental variance. When both internalizing psychopathology and externalizing psychopathology are associated with mental wellbeing, the strongest risk factors for low mental wellbeing are genetic factors that impact on both internalizing psychopathology and externalizing psychopathology, and environmental factors unique to externalizing psychopathology. In this model, genetic risk factors for externalizing psychopathology predict, albeit weakly, higher levels of mental wellbeing. PMID:22506307

Maternal depression is a known risk factor for poor outcomes for children. Pathways to these poor outcomes relate to reduced maternal responsiveness or sensitivity to the child. Impaired responsiveness potentially impacts the feeding relationship and thus may be a risk factor for inappropriate feeding practices. The aim of this study was to examine the longitudinal relationships between self-reported maternal post-natal depressive symptoms at child age 4 months and feeding practices at child age 2 years in a community sample. Participants were Australian first-time mothers allocated to the control group of the NOURISH randomized controlled trial when infants were 4 months old. Complete data from 211 mothers (of 346 allocated) followed up when their children were 2 years of age (51% girls) were available for analysis. The relationship between Edinburgh Postnatal Depression Scale (EPDS) score (child age 4 months) and child feeding practices (child age 2 years) was tested using hierarchical linear regression analysis adjusted for maternal and child characteristics. Higher EPDS score was associated with less responsive feeding practices at child age 2 years: greater pressure [β = 0.18, 95% confidence interval (CI): 0.04-0.32, P = 0.01], restriction (β = 0.14, 95% CI: 0.001-0.28, P = 0.05), instrumental (β = 0.14, 95% CI: 0.005-0.27, P = 0.04) and emotional (β = 0.15, 95% CI: 0.01-0.29, P = 0.03) feeding practices (ΔR(2) values: 0.02-0.03, P < 0.05). This study provides evidence for the proposed link between maternal post-natal depressive symptoms and lower responsiveness in child feeding. These findings suggest that the provision of support to mothers experiencing some levels of depressive symptomatology in the early post-natal period may improve responsiveness in the child feeding relationship. © 2014 John Wiley & Sons Ltd.

Genetic predisposition and environmental influences are both important factors in the development of problematic behavior leading to substance use in adolescence. Involvement with delinquent peers also strongly predicts adolescent externalizing behavior. Several lines of evidence support a role of GABRA2 on externalizing behavior related to disinhibition. However, whether this genetic association is influenced by the environment such as peer behavior remains unknown. We examined the moderating role of GABRA2 genetic variation on the socialization model of delinquent peer affiliation (at ages 12-14 years) on externalizing behavior (at ages 15-17 years) in the Michigan Longitudinal Study (MLS) adolescent sample. The sample consisted of 244 adolescents (75 females and 152 with at least one parent with a DSM-IV lifetime alcohol dependence/abuse diagnosis). Peer delinquent activity reported by the participant and teacher-reported adolescent externalizing behavior (Teacher Report Form (TRF) were assessed. No main effect of the GABRA2 SNP rs279826, which tags a large haplotype, on externalizing behavior was observed. However, there was a statistically reliable GABRA2 × peer delinquency interaction. The effect of peer delinquent involvement on externalizing scores and the rule breaking subscale is significantly stronger for those with the GG genotype compared to A-carriers, whereas there was no effect of genotype on externalizing in the absence of peer delinquent involvement. No interaction was observed for the aggression subscale. Our results suggest that the genetic effect of GABRA2 on externalizing behavior, more specifically on rule breaking is, at least in part, due to its effect on susceptibility to environmental exposure (i.e., peer delinquency).

We report a case of a 60-year-old man diagnosed with papillary thyroid cancer who had a relapse seen only in the brain at FDG PET on standard images. Total thyroidectomy was performed in July 2013 after initial diagnosis. Patient received I ablation in December 2013, followed by external beam radiotherapy to the neck. In September 2015, the patient presented with neurological symptoms. Brain MRI showed multiple brain metastases later confirmed on histopathology. An FDG PET/CT scan was performed to evaluate the whole body in November 2015. Multiple hypermetabolic lesions were identified in the brain with no other lesion up to mid thighs.

Previous research has shown a wide array of age-related declines in vision. The current study examined the effects of perceptual learning (PL), external noise, and task difficulty in fine orientation discrimination with older individuals (mean age 71.73, range 65-91). Thirty-two older subjects participated in seven 1.5-h sessions conducted on separate days over a three-week period. A two-alternative forced choice procedure was used in discriminating the orientation of Gabor patches. Four training groups were examined in which the standard orientations for training were either easy or difficult and included either external noise (additive Gaussian noise) or no external noise. In addition, the transfer to an untrained orientation and noise levels were examined. An analysis of the four groups prior to training indicated no significant differences between the groups. An analysis of the change in performance post-training indicated that the degree of learning was related to task difficulty and the presence of external noise during training. In addition, measurements of pupil diameter indicated that changes in orientation discrimination were not associated with changes in retinal illuminance. These results suggest that task difficulty and training in noise are factors important for optimizing the effects of training among older individuals. Copyright © 2013 Elsevier B.V.

Is post-natal growth during the first 2 years of life in IVF singletons affected by type of medium used for culturing human embryos during an IVF treatment? The in vitro culture of human embryos in medium from Cook resulted in singletons with a lower weight during the first 2 years of life compared with singletons born after embryo culture in medium from Vitrolife. In a previous study, we reported that type of medium used for culturing human IVF embryos during the first few days after fertilization until fresh embryo transfer significantly affects fetal growth and consequently birthweight of the resulting singletons. From July 2003 to December 2006, a total of 1432 IVF treatment cycles with fresh embryo transfer were randomly allocated to have all embryos cultured in medium from Vitrolife AB (n = 715) or from Cook (n = 717). Two years after delivery, questionnaires were sent to the parents of all children requesting data about weight, height and head circumference around 1, 2, 3, 4, 6, 7.5, 9, 11, 14, 18 and 24 months of age. These measurements were collected as part of the children's health programme at municipal infant welfare centres in the Netherlands by health professionals unaware of this study. Patients requiring donor oocytes or applying for PGD were excluded from the study. From the 294 live born singletons that fulfilled our inclusion criteria, 29 were lost to follow-up. The remaining 265 singletons (Cook group: 117, Vitrolife group: 148) were included in the analysis. Data analysis included linear regression, to compare cross-sectionally weight standard deviation score (SDS), height SDS and head circumference, and the first order Berkey-Reed model for a longitudinal analysis of the growth data. Singletons in the Vitrolife group were heavier during the first 2 years of life compared with singletons in the Cook group. Cross-sectional analyses showed that adjusted weight SDS differed between groups at 1 (0.35 ± 0.14, P = 0.010), 2 (0.39 ± 0.14, P = 0

It remains unclear whether feelings of being disabled are a relevant psychological factor that determines long term outcome after percutaneous coronary intervention (PCI). Therefore, we evaluated 'feelings of being disabled' as an independent risk factor for mortality 12years post-PCI. The study population comprised a consecutive series of CAD patients (n=845) treated with PCI as part of the Taxus-Stent Evaluated At Rotterdam Cardiology Hospital (T-SEARCH) registry. Of these patients n=646 (age 63years, 75% male) completed the subscale 'feelings of being disabled' of the Heart Patients Psychological Questionnaire (HPPQ), within the first month after PCI. At 12year follow-up, n=209 patients (32%) died. Of the 162 females n=73 (45%) experienced high feelings of being disabled (High-FOBD) and of the 484 males, n=134 (28%) reported high-FOBD. Patients with high feelings of being disabled had a two-fold increased risk of mortality at 12-year follow-up (HR=1.86, 95% CI=1.41-2.45). After adjusting, high feelings of being disabled remained a predictor of 12-year mortality (HR=2.53, 95% CI=1.30-4.90). This study confirms that psychosocial variables like feelings of being disabled influence cardiac morbidity and mortality. Furthermore, there is no difference in mortality between men and women with high feelings of being disabled 12years post-PCI. It is important that clinicians are aware that PCI-patients who feel disabled have a less favorable survival and that the difference in survival is even greater for women who feel disabled.

Deep Vadose Zone Treatability Test for the Hanford Central Plateau: Interim Post-Desiccation Monitoring Results, Fiscal Year 2014

DOE Office of Scientific and Technical Information (OSTI.GOV)

Truex, Michael J.; Strickland, Christopher E.; Johnson, Christian D.

Over decades of operation, the U.S. Department of Energy (DOE) and its predecessors have released nearly 2 trillion L (450 billion gal.) of liquid into the vadose zone at the Hanford Site. Much of this discharge of liquid waste into the vadose zone occurred in the Central Plateau, a 200 km 2 (75 mi 2) area that includes approximately 800 waste sites. Some of the inorganic and radionuclide contaminants in the deep vadose zone at the Hanford Site are at depths below the limit of direct exposure pathways, but may need to be remediated to protect groundwater. The Tri-Party Agenciesmore » (DOE, U.S. Environmental Protection Agency, and Washington State Department of Ecology) established Milestone M 015 50, which directed DOE to submit a treatability test plan for remediation of technetium-99 (Tc-99) and uranium in the deep vadose zone. These contaminants are mobile in the subsurface environment and have been detected at high concentrations deep in the vadose zone, and at some locations have reached groundwater. Testing technologies for remediating Tc-99 and uranium will also provide information relevant for remediating other contaminants in the vadose zone. A field test of desiccation is being conducted as an element of the DOE test plan published in March 2008 to meet Milestone M 015 50. The active desiccation portion of the test has been completed. Monitoring data have been collected at the field test site during the post-desiccation period and are reported herein. This is an interim data summary report that includes about 3 years of post-desiccation monitoring data. The DOE field test plan proscribes a total of 5 years of post-desiccation monitoring.« less

To investigate constancy, within a treatment session, of the time lag relationship between implanted markers in abdominal tumors and an external motion surrogate. Six gastroesophageal junction and three pancreatic cancer patients (IRB-approved protocol) received two cone-beam CTs (CBCT), one before and one after treatment. Time between scans was less than 30 min. Each patient had at least one implanted fiducial marker near the tumor. In all scans, abdominal displacement (Varian RPM) was recorded as the external motion signal. Purpose-built software tracked fiducials, representing internal signal, in CBCT projection images. Time lag between superior-inferior (SI) internal and anterior-posterior external signals was found by maximizing the correlation coefficient in each breathing cycle and averaging over all cycles. Time-lag-induced discrepancy between internal SI position and that predicted from the external signal (external prediction error) was also calculated. Mean ± standard deviation time lag, over all scans and patients, was 0.10 ± 0.07 s (range 0.01-0.36 s). External signal lagged the internal in 17/18 scans. Change in time lag between pre- and post-treatment CBCT was 0.06 ± 0.07 s (range 0.01-0.22 s), corresponding to 3.1% ± 3.7% (range 0.6%-10.8%) of gate width (range 1.6-3.1 s). In only one patient, change in time lag exceeded 10% of the gate width. External prediction error over all scans of all patients varied from 0.1 ± 0.1 to 1.6 ± 0.4 mm. Time lag between internal motion along SI and external signals is small compared to the treatment gate width of abdominal patients examined in this study. Change in time lag within a treatment session, inferred from pre- to post-treatment measurements is also small, suggesting that a single measurement of time lag at the session start is adequate. These findings require confirmation in a larger number of patients.

This study investigated whether the parenting stress-child externalizing behavior link is moderated by children's emotional reactivity, as indexed by skin conductance responses (SCRs). Participants were 61 children aged 9-12 years and their mothers. Mothers completed measures of parenting stress and their children's externalizing symptoms; children also reported on their externalizing behavior. Children's SCRs were assessed during the viewing of standardized pleasant, unpleasant, and neutral pictures. Cluster analysis on SCRs identified two groups, labeled Lower SCRs and Higher SCRs. Regression analyses indicated that among children with lower SCRs, those exposed to increased parenting stress reported more externalizing symptoms, whereas those who experienced low parenting stress reported similar rates of externalizing problems as children with higher SCRs. No effect of parenting stress emerged for children with higher SCRs. Findings suggest that higher parenting stress renders children with lower, as opposed to higher, SCRs to emotional stimuli more vulnerable to externalizing problems.

A Post-synthetic Modification of II–VI Nanoparticles to Create Tb3+ and Eu3+ Luminophores

2013-01-01

We describe a novel method for creating luminescent lanthanide-containing nanoparticles in which the lanthanide cations are sensitized by the semiconductor nanoparticle’s electronic excitation. In contrast to previous strategies, this new approach creates such materials by addition of external salt to a solution of fully formed nanoparticles. We demonstrate this post-synthetic modification for the lanthanide luminescence sensitization of two visible emitting lanthanides (Ln), Tb3+ and Eu3+ ions, through ZnS nanoparticles in which the cations were added post-synthetically as external Ln(NO3)3·xH2O salt to solutions of ZnS nanoparticles. The post-synthetically treated ZnS nanoparticle systems display Tb3+ and Eu3+ luminescence intensities that are comparable to those of doped Zn(Ln)S nanoparticles, which we reported previously (J. Phys. Chem. A, 2011, 115, 4031–4041). A comparison with the synthetically doped systems is used to contrast the spatial distribution of the lanthanide ions, bulk versus surface localized. The post-synthetic strategy described in this work is fundamentally different from the synthetic incorporation (doping) approach and offers a rapid and less synthetically demanding protocol for Tb3+:ZnS and Eu3+:ZnS luminophores, thereby facilitating their use in a broad range of applications.

The interaction between a temperament profile (four groups determined by high vs. low resistance to control [unmanageability] and unadaptability [novelty distress]) and family stress in predicting externalizing problems at school in children followed from kindergarten through 8th grade (ages 5 – 13) was investigated. The sample consisted of 556 families (290 boys). At Time 1 just prior to kindergarten, mothers retrospectively reported on their child’s temperament during infancy. Each year, mothers reported stress and teachers reported children’s externalizing problems. Temperament profile was tested as a moderator of the stress-externalizing association for various time periods. Results indicated that the combination of high resistance to control and high unadaptability strengthens the stress-externalizing association. Findings are discussed in terms of possible underlying mechanisms. PMID:23438634
