Adaptation of the Regulation of Emotions Questionnaire (REQ) for Adolescents

Current literature demonstrated a strong relationship between emotional regulation or dysregulation and mental health. Several attempts have been made to assess how human beings regulate specifi c emotions they face. The purpose of the current study was to investigate psychometric properties of the Regulation of Emotions Questionnaire (REQ) developed by Phillips and Power (2007) in Turkish adolescents. In order to test the construct validity of the REQ, both exploratory and confi rmatory factor analyses were carried out. Results of EFA and DFA yielded four subscales (external-dysfunctional, internal-dysfunctional, internal-functional, and external-dysfunctional) alike the original study, and 18- item of original 19 items. Criterion validity study was run with 190 subjects and yielded signifi cant correlations were obtained between the REQ and Strengths and Diffi culties Questionnaire, Brief Multidimensional Students' Life Satisfaction Scale and Psychosomatic Symptoms Subscale of Rosenberg Self-esteem Scale. The questionnaire has satisfactory internal consistency values varied from . 57 to . 76. Test-retest reliability study was conducted with 175 subjects and the correlations varied from . 51 and . 70. Findings demonstrated that the scale has good psychometric properties for Turkish adolescents.
Construct Validity of the Individual Work Performance Questionnaire

Objective: To examine the construct validity of the Individual Work Performance Questionnaire (IWPQ). Methods: A total of 1424 Dutch workers from three occupational sectors (blue, pink, and white collar) participated in the study. First, IWPQ scores were correlated with related constructs (convergent validity). Second, differences between known groups were tested (discriminative validity). Results: First, IWPQ scores correlated weakly to moderately with absolute and relative presenteeism, and work engagement. Second, significant differences in IWPQ scores were observed for workers differing in job satisfaction, and workers differing in health. Conclusion: Overall, the results indicate acceptable construct validity of the IWPQ. Researchers are provided with a reliable and valid instrument to measure individual work performance comprehensively and generically, among workers from different occupational sectors, with and without health problems.
Primary Ewing's sarcoma of the maxilla: a clinicopathological study of four cases

The author reports four cases of Ewing's sarcoma primarily located in the maxilla and emphasizes the rarity of such a primary location and the fact that this series contained cases observed at the Department of Otolaryngology of Padua University during the last three years which, though small, is the largest so far reported. In addition to a review of the world literature on the subject, the problems related to the differential diagnosis, in particular from reticulum cell sarcoma of bone, neuroblastoma and olfactory neuroblastoma are discussed. The cases reported are accurately described and histologically documented. Treatment of Ewing's sarcoma is also discussed and, according to the author, the elective therapeutic procedure should consider local irradiation and intermittent but prolonged systemic chemotherapy, leaving mutilating surgery only for recurrent tumours.
Risks and Benefits of Legislative Budgetary Oversight

Although some studies highlight the risks to fiscal discipline, others regard legislative scrutiny as essential for fiscal transparency. We consider it necessary to analyze the potential risks and benefits associated with legislative budgetary oversight simultaneously. In particular, this article aims to ascertain whether legislative budgetary oversight is a risk to fiscal discipline as well as a benefit to budget transparency. Using a sample of 75 countries from around the world for 2009, we find that legislative budgetary oversight is not only a risk in terms of decreasing fiscal discipline but also a benefit, as stronger legislative oversight leads to greater budget transparency.
PERIOPERATIVE PROPHYLACTIC CEPHAZOLIN IN SPINAL SURGERY

We investigated the efficacy of a single dose of 1 g of cephazolin in reducing postoperative infections in patients undergoing 'clean' operations on the lumbar spine. In a double-blind, randomised, trial there were 21 wound or urinary infections in the 71 patients who received placebo and nine in the 70 who received cephazolin (p < 0.05). Nine ofthe placebo patients (12.7%) developed wound infections (complicated by bacteraemia in two) compared with three (4.3%) in the cephazolin group (p = 0.07). Hospital stay was longer for infected patients than for non-infected patients (p < 0.05). Cephazolin-resistant pathogens were isolated more frequently from patients who received cephazolin than from those who received placebo. The use of perioperative antibiotic prophylaxis in elective procedures has been a matter of controversy. Reported wound infection rates without prophylaxis have varied from 0% to 14% in uncontrolled studies and from 3.6% to 11.7% in patients who received only a placebo in controlled trials (Dempsey et al 1988; Haines 1989). The devastating consequences, however, of any infection after neurosurgical procedures supportthe routine use ofprophylactic antibiotics. Few of the controlled studies of antibiotic prophylaxis in orthopaedics have dealt specifically with spinal surgery. We have therefore evaluated the efficacy of a single preoperative dose of cephazolin in a double-blind placebo-controlled trial in lumbar spinal surgery. Cephazolin was chosen because of its activity against methicillin-susceptible Staphylococcus aureus and most of the Enterobacteriacae isolated from faeces and from infected wounds in our hospital. Additional considerations were the low cost and good soft-tissue and bone penetration of this antibiotic. PATIENTS AND METHODS The study was approved by the human rights committee of our medical centre. A total of 166 patients undergoing emergency or elective operations for degenerative disc disease or spinal stenosis between June 1, 1986 and December 31, 1988 were included in the study. The emergency operations were usually performed for acute neurological deficits such as foot-drop or sphincter incompetence. Antibiotic or placebo was given in accordance with a computer-generated random-number list. Numbered vials of identical appearance containing either cephazolin 1 g (Teva, Israel) or placebo were allocated to the patients and administered on arrival at the operating theatre, approximately two hours before surgery. The antibiotic or the placebo was dissolved in 5 ml of saline and given as an intravenous bolus over a period of five minutes. The hand scrub was standardised for the period of the study and consisted of …
Estimation of breathing interval from the photoplethysmographic signals in children

Two important parameters that are generally under continual observation during clinical monitoring are heart rate (HR) variability and breathing interval (BI) of patients. Current HR monitoring during night-long childhood respiratory sleep studies is well tolerated but BI monitoring requires instrumentation, like nasal cannula, that can be less accommodating for children. In this study, BI was extracted from the photoplethysmographic (PPG) signals using a two-stage signal processing technique termed zero-phase digital filtering. Eight children (7 male) aged 8.6 ± 2.6 years were recruited to perform two breathing activities: during tidal and with customized externally applied inspiratory resistive loading (IRL). The accuracy of BI derived from the PPG signals was compared with that estimated by a calibrated air pressure transducer in children. Statistical analysis revealed that mean BI attained from the PPG signals were significantly related during tidal breathing (r2 = 0.76; range 0.61–0.83; p < 0.05) and with the IRL (r2 = 0.79; range 0.68–0.85; p < 0.05) in the absence of motion artefacts. Preliminary findings herein suggest that besides having the capability to monitor HR and arterial blood oxygen saturation measurements, the PPG signals can be used to derive BI for children. This can be an attractive alternative for children who are more disturbed by intrusive techniques in prolonged clinical monitoring.
Building College Readiness: Exploring the Effectiveness of the UNC Academic Summer Bridge Program

Many students enter college without the skills and knowledge needed to successfully perform college-level work. An important leverage point for increasing college readiness is the transition from high school to college. One strategy implemented at postsecondary institutions to ease this transition, boost academic and social readiness, and foster students’ academic momentum is the summer bridge program. The purpose of this study was to examine how summer bridge programs influence student persistence and completion. The study used propensity score analysis to examine the impact of five summer bridge programs operating in the UNC system from 2008 to 2014. The analyses showed a positive association between summer bridge participation and persistence to the second and third years. Participation in the program also increased the likelihood of graduating in 4 years. Additionally, we provide information on the costs of operating these programs.
Angiogenesis and tumor grading in primary breast cancer patients : an analysis of 158 needle core biopsies

Angiogenesis, the formation of new blood vessels from a preexisting vascular bed, is a complex multistep process. To investigate how tumor angiogenesis correlates with tumor grading in breast carcinoma diagnosed on core biopsy, microvessels were counted (and graded the density of microvessels) within the initial invasive carcinomas of 158 patients. Using light microscopy, the number of microvessels was counted manually in a subjectively selected hot spot (in the most active areas of neovascularization per 400× field), and their values were separated as above or below median (low and high), without knowledge of the outcome in the patient or any other pertinent variable. When the mean values of MVD of the various groups defined by tumor grading were compared, significant difference was noted (P = 2.61E–17). When the mean values of MVD of the groups defined by tumor grading risk were compared, significant difference was noted (P = 7.68E–05). When tumors were classified as high or low MVD, based on a cut-off value (30.70175 microvessels/mm2), cases with high MVD were significantly more numerous in MSBR four patients. MVD did show a relationship with groups defined by MSBR grade (P = 3.25209E–07) or with tumor grading risk (P = 2.54181E–06). Assessment of tumor angiogenesis may therefore prove valuable in selecting patients with early breast carcinoma for aggressive therapy.
Prospective motion correction with continuous gradient updates in diffusion weighted imaging

Despite the existence of numerous motion correction methods, head motion during MRI continues to be a major source of artifacts and can greatly reduce image quality. This applies particularly to diffusion weighted imaging, where strong gradients are applied during long encoding periods. These are necessary to encode microscopic movements. However, they also make the technique highly sensitive to bulk motion. In this work, we present a prospective motion correction method where all applied gradients are adjusted continuously to compensate for changes of the object position and ensure the desired phase evolution in the image coordinate frame. Additionally, in phantom experiments this new technique is used to reproduce motion artifacts with high accuracy by changing the position of the imaging frame relative to the measured object. In vivo measurements demonstrate the validity of the new correction method. Magn Reson Med, 2012. © 2011 Wiley Periodicals, Inc.
Effects of Medical Interventions on Gender Dysphoria and Body Image: A Follow-Up Study

Objective The aim of this study from the European Network for the Investigation of Gender Incongruence is to investigate the status of all individuals who had applied for gender confirming interventions from 2007 to 2009, irrespective of whether they received treatment. The current article describes the study protocol, the effect of medical treatment on gender dysphoria and body image, and the predictive value of (pre)treatment factors on posttreatment outcomes. Methods Data were collected on medical interventions, transition status, gender dysphoria (Utrecht Gender Dysphoria Scale), and body image (Body Image Scale for transsexuals). In total, 201 people participated in the study (37% of the original cohort). Results At follow-up, 29 participants (14%) did not receive medical interventions, 36 hormones only (18%), and 136 hormones and surgery (68%). Most transwomen had undergone genital surgery, and most transmen chest surgery. Overall, the levels of gender dysphoria and body dissatisfaction were significantly lower at follow-up compared with clinical entry. Satisfaction with therapy responsive and unresponsive body characteristics both improved. High dissatisfaction at admission and lower psychological functioning at follow-up were associated with persistent body dissatisfaction. Conclusions Hormone-based interventions and surgery were followed by improvements in body satisfaction. The level of psychological symptoms and the degree of body satisfaction at baseline were significantly associated with body satisfaction at follow-up.
Nested Latin hypercube designs

We propose an approach to constructing nested Latin hypercube designs. Such designs are useful for conducting multiple computer experiments with different levels of accuracy. A nested Latin hypercube design with two layers is defined to be a special Latin hypercube design that contains a smaller Latin hypercube design as a subset. Our method is easy to implement and can accommodate any number of factors. We also extend this method to construct nested Latin hypercube designs with more than two layers. Illustrative examples are given. Some statistical properties of the constructed designs are derived. Copyright 2009, Oxford University Press.
Empirical-Stochastic Ground-Motion Prediction for Eastern North America

An alternative approach based on a hybrid-empirical model is utilized to predict the ground-motion relationship for eastern North America (ENA). In this approach, a stochastic model is first used to derive modification factors from the ground motions in western North America (WNA) to the ground motions in ENA. The ground-motion parameters are then estimated to develop an empirical attenuation relationship for ENA using empirical ground-motion relationships from WNA . W e develop an empirical-stochastic source model for both regions to obtain ground mo- tions at different magnitude-distance range of interest. At short distances (R 30 km) and large magnitudes (Mw 6.4), an equivalent point-source model is carried out to consider the effect of finite-fault modeling on the ground-motion parameters. Source focal depth and Brune stress drop are assumed to be magnitude dependent. We choose three well-defined empirical attenuation relationships for WNA to com- pare the empirical ground-motion processes between the two regions. A composite functional attenuation form is defined, and, in turn, a nonlinear regression analysis is performed by using a genetic algorithm (GA) for a wide range of magnitudes and distances to develop an empirical attenuation relationship from the stochastic ground- motion estimates in ENA. The empirical-stochastic attenuation relationship for hor- izontal peak ground acceleration and spectral acceleration are applicable to earth- quakes of Mw 5.0-8.2 at distances of up to 1000 km. The resulting attenuation model developed in this study is compared with those used in the 2002 national seismic hazard maps, derived in the 2003 Electric Power Research Institute studies and re- corded in ENA. The comparison of the results to the other attenuation functions and the available ENA data show a reasonable agreement for the ENA ground motions.
Cross-cultural investigation of the security knowledge process

Security knowledge is a critical component for computer end users to cope with and ameliorate security threats. Drawing upon learning theory and innovation diffusion theory, this study examines individuals' security knowledge process, focusing on spyware. In addition, a moderating effect of culture is examined in security knowledge process between the USA and Republic of Korea. The results indicate that spyware awareness is an intermediary between security familiarity and spyware knowledge, and there is a moderating cultural effect between spyware awareness and spyware knowledge. This study highlights the importance of learning procedures and cultural effects in the security knowledge context.
Predictors and Outcomes of Health-Related Quality of Life in Adults with CKD.

BACKGROUND AND OBJECTIVES Low health-related quality of life is associated with increased mortality in patients with ESRD. However, little is known about demographic and clinical factors associated with health-related quality of life or its effect on outcomes in adults with CKD. DESIGN, SETTINGS, PARTICIPANTS, & MEASUREMENTS Data from 3837 adult participants with mild to severe CKD enrolled in the prospective observational Chronic Renal Insufficiency Cohort and Hispanic Chronic Renal Insufficiency Cohort Studies were analyzed. Health-related quality of life was assessed at baseline with the Kidney Disease Quality of Life-36 and its five subscales: mental component summary, physical component summary, burden of kidney disease (burden), effects of kidney disease (effects), and symptoms and problems of kidney disease (symptoms). Low health-related quality of life was defined as baseline score >1 SD below the mean. Using Cox proportional hazards analysis, the relationships between low health-related quality of life and the following outcomes were examined: (1) CKD progression (50% eGFR loss or incident ESRD), (2) incident cardiovascular events, and (3) all-cause death. RESULTS Younger age, women, low education, diabetes, vascular disease, congestive heart failure, obesity, and lower eGFR were associated with low baseline health-related quality of life (P<0.05). During a median follow-up of 6.2 years, there were 1055 CKD progression events, 841 cardiovascular events, and 694 deaths. Significantly higher crude rates of CKD progression, incident cardiovascular events, and all-cause death were observed among participants with low health-related quality of life in all subscales (P<0.05). In fully adjusted models, low physical component summary, effects, and symptoms subscales were independently associated with a higher risk of incident cardiovascular events and death, whereas low mental component summary was independently associated with a higher risk of death (P<0.05). Low health-related quality of life was not associated with CKD progression. CONCLUSIONS Low health-related quality of life across several subscales was independently associated with a higher risk of incident cardiovascular events and death but not associated with CKD progression.
Can Perceptions of an Individual’s Organizational Citizenship Be Influenced Via Strategic Impression Management Messaging?

A two-part investigation explored whether strategic messaging can influence others’ perceptions of one’s organizational citizenship. In a first study, inductive analysis of interviews (N = 24) revealed working adults hold implicit rules for how (and how not) to present themselves to their colleagues as good citizens: The rules require organizational members’ attempt to avoid being interpreted by colleagues as motivated by personal gain or working through ostentatious means. Then, the content of impression management (IM) messages were crafted—based on these rules—and used for a message-processing experiment (N = 274). Analysis demonstrated working adults’ perceptions of organizational citizenship behavior were influenced by strategic self- and other-referential messaging regarding motives and means. Results imply that strategic IM messaging, which conforms to the rules of organizational citizenship behavior impression-construction, are rewarded with audience perceptions of being citizenly. Implications for IM in the workplace are discussed.
Inhibition of survivin reduces cell proliferation and induces apoptosis in human endometrial cancer

Endometrial cancer is a common gynecologic malignancy among women. The molecular mechanisms involved in the progression of endometrial cancer are unclear, which has hampered the development of an effective treatment. Survivin, a newly identified member of the inhibitor of apoptosis (IAP) family, regulates 2 critical processes in neoplastic transformation: cell proliferation and apoptosis.
Mediation of Extroversion and Self-esteem on Relationship between Family Atmosphere and Loneliness in Rural Parent-absent Children

Objective: To investigate whether the relationship of cold-and-cheerless family atmosphere with Parent-absent children's loneliness was mediated by extroversion and self-esteem. Methods: Scales measuring Family atmosphere,Loneliness, Extroversion and Self-esteem were administered 2 times to 207 children in rural areas over a 2.5-year period.Results: 1Pretest family atmosphere could positively predict both pretest and posttest loneliness in Parent-absent-children. 2Pretest extroversion and self-esteem jointly partially mediated the prediction of pretest family atmosphere to pretest loneliness, and posttest extroversion and self-esteem partially co-mediated the effect of pretest family atmosphere on posttest loneliness. Conclusion: The cold-and-cheerless family atmosphere in rural Parent-absent children has synchronous and diachronic predictive effect on the loneliness, which was mediated by extroversion and self-esteem.
Does Low-Dose Hydrocortisone Therapy Prevent Ventilator-Associated Pneumonia in Trauma Patients?

The incidence of ventilator-associated pneumonia (VAP) is particularly high in trauma patients. Immediate acute inflammation response is one of the hallmarks of multiple trauma. This phenomenon is associated with an immunosuppression state and may increase the risk of VAP. In our study, we aimed to evaluate whether low-dose steroids prevent VAP onset in multiple trauma patients. All adult patients admitted in our intensive care unit (ICU) for multiple trauma with predicted duration of mechanical ventilation over 48 hours were included. We compared 2 different periods: a retrospective cohort of patients who did not receive low-dose steroids for VAP prevention and a prospective cohort of patients who received hydrocortisone with a dose of 100 mg/8 hours for a scheduled period of 7 days. We included 175 patients: 92 in the steroids (−) group and 83 in the steroids (+) group. The incidence of VAP was not different between the 2 studied groups (29.3% and 26.5%; P = 0.676). When predictive factors of VAP onset were studied in multivariate analysis, steroids had no preventive effect on VAP [OR = 1.6; 95% confidence interval, 0.73–3.6; P = 0.234]. We did not find any difference between the 2 groups, neither in terms of ICU length of stay (respectively, 11 ± 9.7 days vs. 12.3 ± 10.7 days; P = 0.372) nor in terms of ICU mortality (29.3% vs 24.1%; P = 0.434).
