Do obsessive compulsive symptoms mediate the relationship between maternal eating psychopathology and restrictive feeding practices?
Authors: Farrow Claire V. , Blissett Jacqueline 
Published: August 2008

AbstractObjective:Symptoms of maternal eating disorders have been linked with the use of maladaptive restrictive child feeding practices. However, how these symptoms impact upon restriction in child feeding is poorly understood. The aims of this research were to assess whether symptoms of obsessive compulsiveness, which are often comorbid with eating disorder symptoms, mediate the relationships between maternal eating disorder symptoms and the use of restrictive feeding practices.Method:A total of 128 mothers of children aged 2–6 years completed measures of their restrictive feeding practices, symptoms of eating disorders, and obsessive compulsiveness.Results:Maternal restriction was positively correlated with symptoms of drive for thinness, bulimia, and checking and cleaning obsessions and compulsions. Cleaning obsessions and compulsions mediated the relationships between maternal drive for thinness and feeding restriction.Conclusion:Cleaning obsessions and compulsions may help to explain the relationships between some symptoms of maternal eating disorders and the use of restrictive feeding practices. © 2008 by Wiley Periodicals, Inc.

Staudinger Reaction as a Way Out To Avoid Cyclization in the Reaction of Silylated Dichloro(hydrazino)phosphane with Trimethylsilyl Azide
Authors: Schulz Axel , Villinger Alexander 
Published: August 2008

AbstractReaction of dichloro‐N,N′,N′‐[tris(trimethylsilyl)]hydrazinophosphane (1) with Me3SiN3 leads after an initial chlorine/azide exchange in a Staudinger reaction to a new phosphorus azide. The in situ formed phosphoranimine reacts with GaCl3 by Me3SiCl elimination, resulting in a phosphoranimino–dichlorogallane, which dimerizes to a Ga2N2‐four‐membered ring. The overall reaction at ambient temperature represents a fast and clean high‐yielding reaction (reaction time 2 h). The dimer of the formed azido–phosphoranimino–dichlorogallane was fully characterized and shown to be stable to temperatures above 103 °C.(© Wiley‐VCH Verlag GmbH & Co.

Biphenyl‐Based Disc‐ vs. Rod‐Shaped Phenylacetylenes: Mesomorphism and Electronic Properties
Authors: Hennrich Gunther , Ortiz Pedro D. , Cavero Emma , Hanes Robert E. , Serrano José Luis 
Published: August 2008

AbstractA standard Sonogashira coupling protocol has been applied for the preparation of a C3‐symmetric phenylacetylene (2) and the corresponding linear phenylacetylene (3) incorporating terminal biphenyl substituents. The study of the mesomorphic properties of the target compounds, as well as mixtures of both, reveals that only the calamitic biphenylylacetylene 3 forms smectic liquid crystals. Upon investigating the electronic situation of both biphenylylacetylenes by spectroscopic methods and computational calculations, it becomes evident that 2 can be considered the trimeric analogue of 3 which however does not form liquid crystalline phases.(© Wiley‐VCH Verlag GmbH & Co.

Synthesis of Novel Amino‐Acid‐Derived Sulfinamides and Their Evaluation as Ligands for the Enantioselective Transfer Hydrogenation of Ketones
Authors: Zani Lorenzo , Eriksson Lars , Adolfsson Hans 
Published: August 2008

AbstractNovel chiral mono‐sulfinyl diamines bearing a stereogenic sulfur atom were prepared in moderate to good yields starting from amino acids by means of a reductive amination of the corresponding amino aldehydes. Their potential as ligands for asymmetric catalysis was evaluated in the metal‐catalyzed enantioselective transfer hydrogenation of alkyl‐aryl ketones. The catalysts were generated in situ from sulfinamides 1a–i and arene complexes of rhodium and ruthenium, and the catalytic reductions led to the formation of chiral alcohols with up to 91 % ee.

Identification as an organizational anchor: how identification and job satisfaction combine to predict turnover intention
Authors: de Moura Georgina Randsley , Abrams Dominic , Retter Carina , Gunnarsdottir Sigridur , Ando Kaori 
Published: August 2008

AbstractThe article examines the role of organizational identification and job satisfaction in relation to turnover intentions in seven organizations. Two models are proposed in which either job satisfaction or organizational identification was treated as a mediator of the other's relationship with turnover intention. The organizations varied in terms of culture (Japan vs. UK), and institutional domain (academic, business, health, mail, legal). Within each organization, and meta‐analytically combined across the seven samples (N = 1392), organizational identification mediated the relationship between job satisfaction and turnover intention more than job satisfaction mediated the relationship between organizational identification, and turnover intention. Organizational identification also had the larger overall relationship with turnover intention. This pattern remained true when gender, age, type of organization, culture, and length of tenure were accounted for, although the direct relationship between job satisfaction and turnover intention was stronger in private than public organizations and when the ratio of men was higher. The findings are consistent with a social identity theory (SIT) perspective and with the idea that identification is a more proximal predictor of turnover intention. Over and above job satisfaction, organizational identification offers a strong psychological anchor that discourages turnover intention in a range of organizational contexts.

Medical demography and intergenerational inequalities in general practitioners' earnings
Authors: Dormont B. , Samson A.‐L. 
Published: August 2008

AbstractThis article examines the link between restrictions on the number of physicians and general practitioners' (GPs) earnings. Using a representative panel of 6016 French self‐employed GPs over the years 1983–2004, we estimate an earnings function to identify experience, time and cohort effects. The estimated gap in earnings between ‘good’ and ‘bad’ cohorts can be as large as 25%. GPs who began their practices during the eighties have the lowest permanent earnings: they belong to the large cohorts of the baby‐boom and face the consequences of an unlimited number of places in medical schools. Conversely, the decrease in the number of places in medical schools led to an increase in permanent earnings of GPs who began their practices in the mid‐nineties. A stochastic dominance analysis shows that unobserved heterogeneity does not compensate for average differences in earnings between cohorts. These findings suggest that the first years of practice are decisive for a GP. If competition between physicians is too intense at the beginning of their careers, they will suffer from permanently lower earnings. To conclude, our results show that the policies aimed at reducing the number of medical students succeeded in buoying up physicians' permanent earnings. Copyright © 2008 John Wiley & Sons, Ltd.
Expenditure dispersion and dietary quality: evidence from Canada
Authors: Beatty Timothy K. M. 
Published: August 2008

AbstractThis paper examines links between the way in which a household spreads their food expenditure over time and the dietary quality of the food they purchase. I find that households who make more frequent, smaller food purchases buy healthier foods than households who make fewer, larger purchases. These households are more likely to purchase foods with a lower share of total calories from fats, saturated fats and a larger share of calories from fruits and vegetables. The analysis is extended using quantile regression. The effect of expenditure dispersion is found to be largest among households with poor diets i.e. those households with diets high in saturated fats and low in fruits and vegetables.

AbstractBackground.In the context of the Danish Head and Neck Cancer Group, nationwide material from 1992–2001 was analyzed to study the extent and nature of the disease, evaluate treatment, compare staging systems, and examine prognosis and survival.Methods.Review of 68 consecutive cases: 47 squamous cell carcinoma, 10 basal cell carcinoma, and 11 other histologies. Moody (modified Pittsburgh) stages were T1 (26), T2 (9), T3 (8), T4 (23), Tx (2). Sixty‐four patients were treated with curative intent: 24 primary radiotherapy, 18 primary surgery, and 22 combined. Surgery was limited to tumor excision and mastoidectomy and in 1 case temporal bone excision.Results.Twenty‐seven of 28 recurrences involved primary site. Kaplan–Meier analysis showed 5‐year locoregional control of 48%, disease‐specific survival 57%, and overall survival 44%.Conclusion.This nationwide study confirmed that local failure is the main problem, and future improvements should focus on more aggressive local treatment. © 2008 Wiley Periodicals, Inc.

Published: August 2008

AbstractBackground.The aim of this study was to identify the prognostic variables in mucosal melanoma of the head and neck.Methods.A retrospective review of 61 cases over a 41‐year period was undertaken. Local, regional, and distant failures were major outcome measures. Demographic, clinical, and pathological parameters were identified and correlated with outcomes.Results.The median age at diagnosis was 68 years. Sinonasal cavity involvement occurred in 80.3% of patients and 16.4% occurred in the oral cavity. Local, regional, and distant recurrences were 60.7%, 19.7%, and 49.2%, respectively. Two‐year and 5‐year disease‐free survivals were 25.8% and 8%, respectively. Disease‐specific survival at 5 years was 28.7%. Age <50 years significantly correlated with a longer median survival time.Conclusion.The most common occurrence site was the sinonasal cavity. Local and distant recurrences are common irrespective of treatment modalities. Younger patients have a relatively better prognosis. Disseminated disease is common and the overall prognosis is poor. © 2008 Wiley Periodicals, Inc. Head Neck, 2008

Authors: Bakhos David , Lescanne Emmanuel , Beutter Patrice , Morinière Sylvain 
Published: August 2008

AbstractBackground.The aim of the retrospective study was to compare the indications, the postoperative outcomes, and the survival of the supracricoid laryngectomy with cricohyoidoepiglottopexy and the anterior frontal laryngectomy.Method.Nineteen patients who underwent cricohyoidoepiglottopexy (group I) and 23 patients who underwent reconstructive anterior frontal laryngectomy (group II) from January 1992 and December 2004 have been reviewed. We have compared their respective indications and postoperative outcomes.Results.There were no differences for median time before decanulation. Median time for removal feeding tube, for first oral alimentation, and hospital stay period were significantly shorter in group II. Five‐year survival was 85% (group I) and 95% (group II). Local tumor control was obtained in 83% in group I and in 87% in group II.Conclusion.Cricohyoidoepiglottopexia (CHEP) was used more often than anterior frontal laryngectomy when there was contralateral vocal fold spread but resulted in longer postoperative outcomes. © 2008 Wiley Periodicals, Inc.

Evaluation of postoperative drainage with application of platelet‐rich and platelet‐poor plasma following hemithyroidectomy: A randomized controlled clinical trial
Authors: Yoo John , Roth Kathryn , Hughes Brian , Fung Kevin , Franklin Jason , Lampe Howard , Pietrzak William S. 
Published: August 2008

AbstractBackground.Platelet‐rich plasma (PRP) and platelet‐poor plasma (PPP) have been used to improve hemostasis and wound healing after surgery; however, randomized controlled trials proving their efficacy are lacking.Methods.Hemithyroidectomy was performed on 52 patients. Autologous PRP and PPP were applied during wound closure in the treatment group, while saline was applied in the controls. Outcome measures were postoperative drainage, pain, analgesic use, and length of hospital stay.Results.The 24‐hour cumulative drainage was reduced by 29.3% in the treatment group (44.9 mL vs 63.5 mL, p = .039). The treatment group required less analgesic medication despite similar pain scores; however, the difference was not significant. There was a trend toward decreased length of stay for thePRP/PPP group (p = .059).Conclusions.Hemithyroidectomy served as a stringent test to evaluate the wound‐healing capacity of platelet‐rich and platelet‐poor plasma. This study provides evidence that PRP and PPP reduced postoperative drainage in soft‐tissue surgery. © 2008 Wiley Periodicals, Inc. Head Neck, 2008

AbstractBackground.Ultrasound‐guided fine‐needle aspiration cytology (US‐FNAC) can be used to diminish the risk of missing occult metastases and for early detection during follow‐up.Methods.A retrospective study was performed in 163 surgically treated patients without palpable neck nodes (N0). One hundred twenty‐six patients underwent planned elective neck dissections, and 37 were planned for a wait‐and‐see strategy, but preoperative US‐FNAC could change this policy if metastases were detected.Results.In the elective neck dissection group, US‐FNAC had a sensitivity of 39%, whereas in the wait‐and‐see group, the sensitivity was 18%. The 5‐year survival in the wait‐and‐see group did not differ from the patients with early oral cancer who underwent an elective neck dissection.Conclusion.Although the sensitivity of US‐FNAC in this study is low, especially in small oral cancer, the prognosis in the wait‐and‐see group is not affected. However, a wait‐and‐see strategy is only advantageous to a minority of the patients. © 2008 Wiley Periodicals, Inc. Head Neck, 2008

Published: August 2008

AbstractBackground.Cervical lymphadenectomy is frequently performed in patients with lateral cervical lymph node metastases to improve regional control of disease. However, there is no consensus regarding the appropriate levels of the neck that need to be dissected. Treatment options that have been advocated include the modified radical neck dissection, limited neck dissections, and selective nodal excisions. In particular, the routine dissection of level V remains controversial due to the attendant morbidity to the spinal accessory nerve. To identify clinical and pathological predictors of cervical node metastases to level V in differentiated thyroid carcinoma, we reviewed our experience at The University of Texas M. D. Anderson Cancer Center for the management of metastatic well‐differentiated thyroid cancer.Methods.We retrospectively analyzed 70 patients who underwent thyroidectomy and neck dissection for well‐differentiated thyroid cancer at M. D. Anderson Cancer Center.Results.In our series, 53% of neck specimens harbored metastatic thyroid carcinoma at level V. Additionally, 13 level V contralateral neck dissections were performed, and 57% were found positive for metastases. The presence of ipsilateral level V metastases was significantly associated with multifocal disease (p <.05), ipsilateral level II (p <.05), III (p <.05), or IV (p <.01) metastases. Furthermore, ipsilateral involvement of level V was associated with contralateral lymph node metastases (p <.05). Age, sex, and size of primary tumor were not found to be associated with level V metastases. Additionally, preoperative imaging was not sensitive for detecting the presence of level V metastases.Conclusion.In our series, cervical metastases from differentiated thyroid carcinoma were commonly present at level V. Patients with multifocal cancer within the thyroid gland, and cervical metastases in the ipsilateral jugular nodes have a higher risk of harboring metastatic disease at level V. We believe that routine dissection of the level V lymph nodes should be performed in the setting of a comprehensive neck dissection for patients with lateral neck metastasis from well‐differentiated thyroid cancer. © 2008 Wiley Periodicals, Inc.

AbstractBackground.Brown tumor occasionally affects the facial bones. Clinically, these lesions can be mistaken for a neoplasm. Opinions are divided on the course of management of the bony lesions once parathyroidectomy has been carried out.Methods.We treated 22 patients with primary hyperparathyroidism and osteitis fibrosa cystica and observed their clinical and biochemical recovery.Results.Fifteen patients (68.2%) had brown tumors in mandible, and 7 (31.8%) in maxilla. After parathyroidectomy, 21 patients had normal total serum calcium values. All brown tumors presented a spontaneous progressive regression; in 18cases, regression was total, with a mean time period of 10months. Two patients had partial regression after nearly 2years. Another 2 patients were lost to follow‐up.Conclusions.After successful parathyroid surgery, the bony lesions tended to regress spontaneously, either partially or completely. However, if the lesion is disfiguring or symptomatic, surgical excision may be indicated. © 2008 Wiley Periodicals, Inc. Head Neck, 2008

Published: August 2008

Abstract

Transient elastography (FibroScan [FS]) is a novel non-invasive tool to assess liver fibrosis/cirrhosis. However, it remains to be determined if other liver diseases such as extrahepatic cholestasis interfere with fibrosis assessment because liver stiffness is indirectly measured by the propagation velocity of an ultrasound wave within the liver. In this study, we measured liver stiffness immediately before endoscopic retrograde cholangiopancreatography and 3 to 12 days after successful biliary drainage in patients with extrahepatic cholestasis mostly due to neoplastic invasion of the biliary tree. Initially elevated liver stiffness decreased in 13 of 15 patients after intervention, in 10 of them markedly. In three patients, liver stiffness was elevated to a degree that suggested advanced liver cirrhosis (mean, 15.2 kPa). Successful drainage led to a drop of bilirubin by 2.8 to 9.8 mg/dL whereas liver stiffness almost normalized (mean, 7.1 kPa). In all patients with successful biliary drainage, the decrease of liver stiffness highly correlated with decreasing bilirubin (Spearman's ρ = 0.67,

P

< 0.05) with a mean decrease of liver stiffness of 1.2 ± 0.56 kPa per 1 g/dL bilirubin. Two patients, in whom liver stiffness did not decrease despite successful biliary drainage, had advanced liver cirrhosis and multiple liver metastases, respectively. The relationship between extrahepatic cholestasis and liver stiffness was reproduced in an animal model of bile duct ligation in landrace pigs where liver stiffness increased from 4.6 kPa to 8.8 kPa during 120 minutes of bile duct ligation and decreased to 6.1 kPa within 30 minutes after decompression.

Conclusion:

Extrahepatic cholestasis increases liver stiffness irrespective of fibrosis. Once extrahepatic cholestasis is excluded (e.g., by liver imaging and laboratory parameters) transient elastography is a valuable tool to assess liver fibrosis in chronic liver diseases. (Hepatology 2008.)

AbstractWe want to develop a dialogue between geophysicists and hydrologists interested in synergistically advancing process based watershed research. We identify recent advances in geophysical instrumentation, and provide a vision for the use of electrical and magnetic geophysical instrumentation in watershed scale hydrology. The focus of the paper is to identify instrumentation that could significantly advance this vision for geophysics and hydrology during the next 3–5 years. We acknowledge that this is one of a number of possible ways forward and seek only to offer a relatively narrow and achievable vision. The vision focuses on the measurement of geological structure and identification of flow paths using electrical and magnetic methods. The paper identifies instruments, provides examples of their use, and describes how synergy between measurement and modelling could be achieved. Of specific interest are the airborne systems that can cover large areas and are appropriate for watershed studies. Although airborne geophysics has been around for some time, only in the last few years have systems designed exclusively for hydrological applications begun to emerge. These systems, such as airborne electromagnetic (EM) and transient electromagnetic (TEM), could revolutionize hydrogeological interpretations. Our vision centers on developing nested and cross scale electrical and magnetic measurements that can be used to construct a three‐dimensional (3D) electrical or magnetic model of the subsurface in watersheds. The methodological framework assumes a ‘top down’ approach using airborne methods to identify the large scale, dominant architecture of the subsurface. We recognize that the integration of geophysical measurement methods, and data, into watershed process characterization and modelling can only be achieved through dialogue. Especially, through the development of partnerships between geophysicists and hydrologists, partnerships that explore how the application of geophysics can answer critical hydrological science questions, and conversely provide an understanding of the limitations of geophysical measurements and interpretation.
