Comparison of two methods of administering the Halstead category test
Authors: Wood William D. , Strider Mary Ann 
Published: August 2012

AbstractDeveloped an alternative method of administering Halstead's Category Test that uses answer sheet and latent image developer. The method does not entail bulky apparatus operated by the examiner. There is lessened possibility of examiner error in providing reinforcement and in recording responses. Use of visual rather than auditory reinforcement makes the method useful with the deaf. Performance on alternative and standard methods by psychiatric inpatients (N = 50) was the same, which suggests that the two methods are equivalent.
Marital role dynamics during brief group psychotherapy: Assessment of verbal interactions
Authors: Silbergeld Sam , Thune Elizabeth S. , Manderscheid Ronald W. 
Published: August 2012

AbstractExamined the impact of brief group psychotherapy on the marital and sex roles of five volunteer couples who participated in two, 15‐session, model therapy groups conducted approximately 2 years apart. Assessments are based on Hill Interaction Matrix (HIM) analysis of the style and content of marital partners' verbal behavior during the sessions. Results show that interactional correlates of traditional marital and sex role variations are attenuated, that communication between spouses is improved, and that the therapeutic quality of verbal behavior is enhanced over the course of therapy. Generally, from the perspective of interactional dynamics, these findings suggest that the group psychotherapy model that was being evaluated is an effective mode of brief, precrisis intervention for married couples.
Effectiveness of alpha biofeedback therapy: Negative results
Authors: Watson Charles G. , Herder Joseph 
Published: August 2012

AbstractAssessed the utility of alpha biofeedback training in the treatment of psychiatric patients (N = 66). Biofeedback and placebo biofeedback groups were given alpha or mock‐alpha training sessions, and their improvement on 54 variables was compared to that of no‐treatment controls. Only a chance number of significant differential changes appeared among the three groups. A comparison of these negative results with an earlier study from our laboratory that had yielded positive findings suggested that clinical improvement in alpha biofeedback treatment may be the result of the relaxation training or special verbal instructions often incorporated into alpha training.
Multidimensional change in psychotherapy
Authors: Jones Enrico E. 
Published: August 2012

AbstractAssessed psychotherapy outcome for 177 patients who were seen for an average of 31 therapy hours with the Rating Scales for Outcome of Therapy and a Therapist Questionnaire. Results of a components analysis did not support Storrow's rational groupings of the Rating Scales into five dimensions and suggested that two general areas of psychological adjustment underlie the 11 scales. A second components analysis that included both outcome measures supports only in part the contention that when results from diverse outcome measures are factor analyzed, the factors necessarily are associated with method of measurement rather than substantive dimensions of change.

AbstractInformation related to the growth of fine roots is important for understanding C allocation in trees and the mechanisms of C cycling in ecosystems. Observations using a camera or scanner embedded in the soil enabled us to obtain continuous images of fine‐root‐growth dynamics. However, these methods are still labor‐intensive because the image analysis has to be conducted manually. We developed an automated method for tracking movement or elongation of fine roots using a sequence of scanner images. We also show how data obtained with these methods can be used for calculating fine‐root behavior. Two A4‐size scanners were buried in a mixed forest in Japan and images were taken continuously from within the soil. We preprocessed these images by extracting the fine‐root area from the images and developed an automated calculation plug‐in we named A‐root for tracking growth movement of the tips of fine roots. A‐root and manual‐tracking results were compared using the same images. The results show the A‐root and manual‐tracking methods yielded similar levels of accuracy. The average growth rate of 17 fine roots tracked using the program was 0.16 mm h–1. The observation of the direction of growth in fine roots showed the direction may be influenced by the original root's growth where the fine roots branched, distribution of soil particles, other roots, and the force of gravity. The A‐root analysis also suggested there may be an interaction between speed of growth and changes in direction of growing fine roots.
Dysregulated expression of Slug, vimentin, and E‐cadherin correlates with poor clinical outcome in patients with basal‐like breast cancer

Published: August 2012

AbstractBackgroundAmong the different types of breast cancer, basal‐like breast cancer (BLBC) has an extremely poor prognosis due to its high rate of recurrence and metastasis. The present study aimed to investigate the correlation between the expression of Slug, E‐cadherin, and vimentin, and the clinicopathological characteristics and prognosis of patients with BLBC. We further inferred from these findings whether Slug leads to a poor prognosis in patients with BLBC through epithelial–mesenchymal transition (EMT).MethodsImmunohistochemistry was performed for 441 patients with breast cancer to determine the expression levels of Slug, E‐cadherin, and vimentin. The correlation between protein expression and clinicopathological characteristics of patients with BLBC was evaluated, and these patients were followed up to determine survival rate.ResultsHigh Slug and low E‐cadherin expression in BLBC patients closely correlated with histological grade, lymph node metastasis, tumor‐node‐metastasis (TNM) stage, and lymphatic vessel metastasis. Survival analysis revealed that the poor prognosis of BLBC is associated with TNM stage, high Slug and vimentin expression, and low E‐cadherin levels.ConclusionsHigh Slug expression is closely correlated with poor prognosis in patients with BLBC. We speculate that this may be attributed to the involvement of Slug in the EMT of BLBC. J. Surg. Oncol. 2013;107:188–194. © 2012 Wiley Periodicals, Inc.
Effect of the 532nm pulsed KTP laser in the treatment of Reinke's edema
Authors: Pitman Michael J. , Lebowitz‐Cooper Amy , Iacob Chodrin , Tan Meilin 
Published: August 2012

AbstractObjectives/Hypothesis:To evaluate the effect and safety of the 532nm Pulsed Potassium‐Titanyl‐Phosphate (KTP) laser in the office‐based treatment of patients with Reinke's edema using objective and subjective scaled outcome measures.Study Design:Case Series.Setting:Tertiary hospital center.Subjects:Seven adult females undergoing in‐office KTP laser treatment for Reinke's edema.Methods:Participants were studied pre‐ and posttreatment. Vocal function was evaluated by objective aerodynamic and acoustic analysis. Subjective changes were evaluated using the GRBAS scale, Voice Handicap Index, and videostroboscopy. Histologic effects of the laser were investigated by comparing one patient treated with laser one year prior to excision, one treated with laser just prior to excision, and one control patient who underwent excision without prior laser treatment.Results:At an average postoperative follow up of 17.8 weeks (range 5–78), maximum phonation time trended toward improvement. The median VHI score decreased from 37 to 26 (p=0.150). There was a reduction in each component of the GRBAS scoring and the median fundamental frequency increased from 162 to 186 (p=0.625). Stroboscopic findings demonstrated an intact posttreatment mucosal wave. Histologic comparison of the tissue effects of laser in three patients demonstrated changes in vocal fold vascularity but no acute or long‐term damage to the overlying epithelium.Conclusion:Objective and subjective scaled measures suggest that treatment of Reinke's edema in the office with a 532nm KTP laser may result in improved voice. It appears safe with histologic preservation of the vocal fold vibratory epithelium and persistence of mucosal wave. Laryngoscope, 2012
Polystyrene Solutions: Characterization of Molecular Motional Modes by Spectrally Resolved Low‐ and High‐Field NMR Relaxation
Authors: Cudaj Markus , Cudaj Judith , Hofe Thorsten , Luy Burkhard , Wilhelm Manfred , Guthausen Gisela 
Published: August 2012

AbstractPolystyrene solutions in CDCl3 were examined by different NMR techniques. Diffusion measurements and spectrally resolved frequency‐dependent 1H longitudinal relaxation studies give some insight into the complex molecular motional modes and their frequency dependence, that is, the dispersion of the longitudinal relaxation rate. The newly available spectral resolution at low magnetic field around 20 MHz 1H‐Larmor frequency additionally allows the differentiation of aliphatic and aromatic spectral contributions and, therefore, a more detailed description of the molecular mobility in the frequency range of several MHz compared to the well‐known time‐domain or field‐cycling NMR studies.
Preparation of Soft Microactuators in a Continuous Flow Synthesis Using a Liquid‐Crystalline Polymer Crosslinker
Authors: Fleischmann Eva‐Kristina , Ohm Christian , Serra Christophe , Zentel Rudolf 
Published: August 2012

AbstractWe present the synthesis of a polymeric liquid crystalline (LC) crosslinker and its usage in the preparation of soft microactuators. The microactuators, composed of thermoresponsive liquid crystalline elastomers (LCE), are fabricated in a microfluidic device in a continuous “on the fly” process. The LC polymer crosslinker is miscible with the LC monomer and provides for a rapid polymerization and crosslinking. Most importantly, it promotes an enantiotropic mesophase of the mobile monomer phase, which is not provided by conventional nonmesogenic crosslinkers. This allows an isothermal handling inside the microfluidic setup. Temperature‐driven shape changes up to 65% could be achieved by judiciously optimizing the crosslinking density of the LCE particles.
Integral representation for the solution of the stationary Schrödinger equation in a cone
Authors: Qiao Lei , Deng Guantie 
Published: August 2012

AbstractIn this paper, we consider the Dirichlet problem for the stationary Schrödinger equation in a cone with continuous boundary data. For a solution u of the stationary Schrödinger equation in a cone, we prove that if its positive part u+ satisfying a slowly growing condition, then its negative part u− can also be dominated by a similar slowly growing condition. Meanwhile, u can be represented by its integral in the boundary of the cone.

Gray blood magnetic resonance for carotid wall imaging and visualization of deep‐seated and superficial vascular calcifications
Authors: Koktzoglou Ioannis 
Published: August 2012

AbstractWhite blood and black blood magnetic resonance imaging methods are often used for lumenography and visualization of the arterial wall, respectively. However, the use of white blood imaging invariably obscures arterial wall boundaries, and thus, impedes precise measurement of arterial wall area. Conversely, black blood imaging imposes strict limits on sequence timing to suppress the arterial lumen, and by itself, precludes separation of superficial calcification from the hypointense arterial lumen. In this work, a three‐dimensional arterial wall imaging methodology providing gray blood image contrast is described that remedies the above limitations. When applied to the carotid arteries, the described gray blood imaging method is found to clearly depict the inner and outer arterial wall boundaries as well as superficial and deep‐seated vascular calcifications. A tailored phase‐encoding schedule is also presented that enables concurrent gray and black blood, or “dual contrast,” imaging of the arterial wall with no increase in the acquisition time. Taken together, presented data demonstrate that gray and dual blood contrast magnetic resonance imaging provide an efficient means for viewing and characterizing the composition of atherosclerotic plaques.

Direct imaging of hyperpolarized 129Xe alveolar gas uptake in a mouse model of emphysema
Authors: Iguchi Satoshi , Imai Hirohiko , Hori Yuki , Nakajima Junichi , Kimura Atsuomi , Fujiwara Hideaki 
Published: August 2012

AbstractMRI of hyperpolarized 129Xe dissolved in pulmonary tissues, and blood has the potential to offer a new tool for regional evaluation of pulmonary gas exchange and perfusion; however, the extremely short T and low magnetization density make it difficult to acquire the image. In this study, an ultrashort echo‐time sequence was introduced, and its feasibility to quantitatively assess emphysema‐like pulmonary tissue destruction by a combination of dissolved‐ and gas‐phase 129Xe lung MRI was investigated. The ultrashort echo‐time has made it possible to acquire dissolved 129Xe images with reasonably high spatial resolution of 0.625 × 0.625 mm2 and to obtain T of 0.67 ± 0.30 ms in a spontaneously breathing mouse at 9.4 T. The regional dynamic alveolar gas uptake as well as subsequent transport by pulmonary blood flow was also visualized. The ratio of 129Xe magnetization that diffused into the septa relative to the gas‐phase magnetization F was regionally evaluated. The mean F value of elastase‐treated mice was 2.28 ± 0.46%, which was significantly reduced from that of control mice 3.41 ± 0.48% (P = 0.0052). This reflects the reduced uptake efficiency due to alveolar tissue destruction and is correlated with the histologically derived alveolar surface‐to‐volume ratio.

Mitigation of B1+ inhomogeneity on single‐channel transmit systems with TIAMO
Authors: Orzada Stephan , Johst Sören , Maderwald Stefan , Bitz Andreas K. , Solbach Klaus , Ladd Mark E. 
Published: August 2012

AbstractIn magnetic resonance imaging, there has been a constant drive to higher static magnetic field strengths (B0) to achieve a higher signal‐to‐noise ratio and new or enhanced contrasts. In today's high‐field systems, severe problems regarding the homogeneity of the transmission field are encountered. Recently, an acquisition scheme called Time‐Interleaved Acquisition of Modes has been proposed to tackle the inhomogeneity problems in high‐field magnetic resonance imaging. The basic premise is to excite two (or more) different B modes using static radiofrequency shimming in an interleaved acquisition, where the complementary radiofrequency patterns of the two modes can be exploited to improve overall signal homogeneity. In its usual implementation, a multichannel transmit system is required. In this work, the goal is to present a simple and inexpensive hardware setup which makes it possible to use time‐interleaved acquisition of modes on any single‐channel transmit system while making use of the vendor‐provided single‐channel radiofrequency safety system. To demonstrate the efficacy of this setup, spin echo images from the pelvis are acquired at 7 T exhibiting no complete signal dropouts. Magn Reson Med, 2013. © 2012 Wiley Periodicals, Inc.
Surgical treatment of hepatoblastoma
Authors: Meyers Rebecka L. , Czauderna Piotr , Otte Jean‐Bernard 
Published: August 2012

AbstractSurgical resection remains the cornerstone of cure in hepatoblastoma (HB). Meticulous review of contrast enhanced CT/MR imaging facilitates PRETEXT and POST‐TEXT grouping to determine optimal timing and desired extent of liver resection. Excellent knowledge of liver anatomy is essential and the dissection must ensure protection of the vascular inflow and outflow to the remaining liver at all times. Referral to a liver specialty center in advanced cases may facilitate resectability. Potential surgical complications include bleeding, vascular injury, cardiac arrest, liver failure, and bile leak. The risk of complications can be minimized with preoperative planning, appropriate referral, and precise surgical technique. Pediatr Blood Cancer 2012; 59: 800–808. © 2012 Wiley Periodicals, Inc.

Published: August 2012

ABSTRACTObjectivePrenatal diagnosis of a chromosomal abnormality currently involves the use of an invasive procedure, which has a risk of fetal loss. The aim of this study was to identify whether pregnancies conceived via assisted reproductive technologies were more or less likely to be subjected to an invasive procedure compared with pregnancies that were conceived spontaneously.MethodPopulation data were collated from three private ultrasound clinics across southeast Queensland, Australia.ResultsOf the 15 032 spontaneously conceived pregnancies, 775 (5.2%) had invasive testing, while 95 (6.0%) of the 1581 pregnancies conceived through assisted reproductive technologies had invasive testing. When the uptake of testing is adjusted by the maternal age the assisted reproductive population was significantly less likely to pursue invasive testing (p = 0.003). Similarly when adjusted for the combined first trimester screen risk estimate, the assisted reproduction population is significantly less likely to undergo invasive testing than the spontaneous population (p = 0.005).ConclusionPregnancies conceived using assisted reproductive technologies are significantly less likely to be subjected to invasive testing than pregnancies conceived spontaneously in women of the same age and combined first trimester screen risk. © 2012 John Wiley & Sons, Ltd.
Health‐related quality of life does not differ between short‐term, long‐term and very long‐term cancer survivors in the Swedish general population
Authors: Wikman Anna , Djärv Therese , Johar Asif , Lagergren Pernilla 
Published: August 2012

AbstractBackgroundTime since cancer diagnosis is rarely accounted for in population‐based studies of health‐related quality of life (HRQL) among cancer survivors. Therefore, this study aimed to assess the relationship between time since cancer diagnosis and impairments in HRQL among short‐term, long‐term and very long‐term cancer survivors in the general population.MethodsA cross‐sectional population‐based survey of 4910 Swedish adults aged 40–79 years was conducted between April and June 2008. Three hundred and nineteen cases of cancer were identified, and 4591 participants reported no cancer. Analysis of co‐variance (95% confidence intervals), adjusting for age, gender, education, marital status and non‐cancer co‐morbidity, was performed to compare HRQL ratings, as measured by the European Organisation for Research and Treatment of Cancer QLQ‐C30, between short‐term (<5 years since diagnosis [YSD]), long‐term (5–10 YSD) and very long‐term (>10 YSD) cancer survivors, and with that of a no‐cancer control group.ResultsNo significant differences were observed between the survivor groups across the HRQL scales, with the exception of fatigue and appetite loss, which were greater among the short‐term survivors compared with the very long‐term survivors. For the majority of the HRQL scales, ratings were significantly poorer in the short‐term survivors compared with controls. Long‐term survivors had significantly reduced global quality of life, physical function, social function and fatigue, compared with controls. Differences observed between groups were largely of limited clinical significance. HRQL of very long‐term survivors did not differ from controls.ConclusionsAlthough HRQL was similar between short‐term, long‐term and very long‐term survivors, when compared with the background population, findings suggest that some functional impairments and symptoms are present even at 5–10 YSD.

Prostate cancer treatments and their side effects are associated with increased insomnia
Authors: Savard Josée , Hervouet Séverine , Ivers Hans 
Published: August 2012

AbstractObjectiveBetween 25% and 40% of prostate cancer patients report insomnia symptoms. Although a possible role of androgen deprivation therapy (ADT) and radiation therapy (RTH) and some of their side effects have been postulated, this issue has rarely been investigated. This study aimed to (1) compare the evolution of insomnia symptoms and somatic symptoms, which may affect sleep quality (i.e., hot flashes, night sweats, and urinary symptoms), in patients receiving combined ADT and RTH with that in patients receiving RTH only and (2) assess the mediating role of somatic symptoms in the relationship of ADT and RTH with insomnia symptoms.MethodsSixty men scheduled to receive RTH for prostate cancer, with (n = 28) or without (n = 32) ADT, were assessed prior to receiving any treatment (baseline) and at seven additional times over 16 months (1, 2, 4, 6, 8, 12, and 16 months) using the Insomnia Severity Index and the Physical Symptoms Questionnaire.ResultsA significant interaction effect was found indicating an increase in insomnia scores in ADT–RTH patients at 2, 4, and 6 months, as compared with baseline, and stable scores in RTH patients. A significant mediating role of hot flashes and night sweats was found in the relationship between ADT and insomnia symptoms. The relationship with RTH was also significantly mediated by these two symptoms albeit more strongly by excessive urinary frequency.ConclusionsAndrogen deprivation therapy is associated with an increased risk for insomnia, and side effects of ADT and RTH appear to play a role in the development of insomnia in this population.
