The Moderating Role of Working Memory Capacity and Alcohol‐Specific Rule‐Setting on the Relation Between Approach Tendencies and Alcohol Use in Young Adolescents
Authors: Pieters Sara , Burk William J. , Van der Vorst Haske , Wiers Reinout W. , Engels Rutger C. M. E. 
Published: February 2012

Background:  Dual process models of alcohol addiction propose that the transition from normative alcohol consumption to heavy drinking is the result of an imbalance in interplay between relatively impulsive or automatic and reflective or controlled processes. The current study examines whether impulsive and reflective processes are also detectable in a sample of adolescents with limited alcohol use.Methods:  Specifically, we tested the interaction between alcohol approach tendencies and 2 types of reflective processes, working memory capacity (WMC) and alcohol‐specific rule‐setting, on changes in alcohol use of 238 young adolescents (mean age: 13.82 years). Gender differences in these associations were also explored.Results:  Results showed that WMC did not moderate the relation between approach tendencies and subsequent alcohol use, whereas rule‐setting did, with stronger associations between approach tendencies and alcohol use for male adolescents reporting more permissive parents than male adolescents with parents enforcing stricter rules involving alcohol use. Associations between approach tendencies and subsequent alcohol use did not emerge for female adolescents.Conclusions:  Results indicate that even in a sample of adolescents with limited drinking experience, automatic processes are positively associated with alcohol use for male adolescents that are not motivated by parents to control their drinking.
Religiosity of Adolescents and their Friends and Network Associates: Homophily and Associations With Antisocial Behavior
Authors: French Doran C. , Purwono Urip , Rodkin Philip C. 
Published: February 2012

This study assessed the similarity of adolescents and their friends and peer network associates in religiosity and the extent to which these relationships were associated with antisocial behavior. The sample included 1010 Indonesian (480 male, 530 female) 8th (13.37 years) and 10th grade (15.36 years) students. Adolescents were similar to their mutual friends and network associates (identified using Social Cognitive Mapping) in religiosity, and the religiosity of both friends and network associates added to male adolescents' self‐religiosity in predicting antisocial behavior; these effects were not present for girls. Peers may associate with others similar to themselves in religiosity and these associations may partially explain why religious boys exhibit low levels of aggressive behavior.

Published: February 2012

AbstractWe are reporting on a series of two patients with end‐stage renal disease on hemodialysis, presented for surgical parathyroidectomy secondary refractory hyperparathyroidism. Both patients had failed maximized medical managements, including higher‐than‐usual doses of the calcimimetic cinacalcet (270 and 180 mg/day, respectively). On physical exam, both patients had marked symmetrical craniofacial hypertrophy with coarse distortion of facial features, similar in appearance to past reports of Sagliker syndrome. On X‐ray and computed tomographic exam, they had peculiar areas of bone absorption on the skull, imitating the radiologic appearance of multiple myeloma. Bone biopsy of the maxilla, however, did not show the expected brown tumor, but rather described only fibrosis and reactive bone formations. This phenotype developed while being on cinacalcet, progressed despite escalation of therapy, and improved only after parathyroidectomy. Both patients developed massive “hungry bone syndrome” after parathyroidectomy necessitating prolonged IV calcium infusion. This pattern of severe facial distortion likely represented an adverse consequence of severe tertiary hyperparathyroidism, along with supraphysiologic dose of cinacalcet administration and 25‐hydroxy vitamin D deficiency in sensitive individuals. The genetic base of this observation remained unexplained.

Published: February 2012

Abstract Purpose: This study was designed to collect and compare nurse staffing standards and staffing levels in six counties: the United States, Canada, England, Germany, Norway, and Sweden.Design: The study used descriptive information on staffing regulations and policies as well as actual staffing levels for registered nurses, licensed nurses, and nursing assistants across states, provinces, regions, and countries.Methods: Data were collected from Internet searches of staffing regulations and policies along with statistical data on actual staffing from reports and documents. Staffing data were converted to hours per resident day to facilitate comparisons across countries.Findings: We found wide variations in both nurse staffing standards and actual staffing levels within and across countries, although comparisons were difficult to make due to differences in measuring staffing, the vagueness of standards, and limited availability of actual staffing data. Both the standards and levels in most countries (except Norway and Sweden) were lower than the recommended levels by experts.Conclusions: Our findings demonstrate the need for further attention to nurse staffing standards and levels in order to assure the quality of nursing home care.Clinical Relevance: A high quality of nursing home care requires adequate levels of nurse staffing, and nurse staffing standards have been shown to improve staffing levels.Journal of Nursing Scholarship, 2011; XX:X, XXX–XXX. ©2011 Sigma Theta Tau International.
Novice Nurse Productivity Following Workplace Bullying

Published: February 2012

Abstract Purpose: To determine the prevalence and effects of workplace bullying (WPB) on the work productivity of novice nurses (NNs).Design: Internet‐based descriptive cross‐sectional survey design.Methods: One hundred ninety seven NNs (91.4% female, 8.6% male) in practice less than 2 years completed the Healthcare Productivity Survey, Negative Acts Questionnaire, and a demographic survey.Findings: The majority (72.6%, n= 147) of NNs reported a WPB event within the previous month, with 57.9% (n= 114) the direct targets and another 14.7% (n= 29) witnesses of WPB behaviors. Using a weighted Negative Acts Questionnaire score, 21.3% (n= 43) of NNs were bullied daily over a 6‐month period. When asked if bullied over the past 6 months, approximately 44.7% (n= 88) of NNs reported repeated, targeted WPB, with 55.3% (n= 109) reporting no WPB. WPB acts were primarily perpetrated by more experienced nursing colleagues (63%, n= 126). Further, work productivity regression modeling was significant and NN productivity was negatively impacted by workplace bullying (r=−.322, p= .045).Conclusions: WPB continues in the healthcare environment and negatively affects bullied NNs’ productivity by affecting cognitive demands and ability to handle or manage their workload.Clinical Relevance: Healthcare facilities should continue to measure WPB in the work environment after policy implementation as well as eliminate negative behaviors through root‐cause analysis to correct environmental factors associated with WPB.Journal of Nursing Scholarship, 2011; XX:X, XXX–XXX. ©2011 Sigma Theta Tau International.
Soft tissue topography and dimensions lateral to single implant‐supported restorations. A cross‐sectional study
Authors: Chang Moontaek , Wennström Jan L. 
Published: February 2012

AbstractObjectivesThe aim was to evaluate potential relationships between the implant position relative to adjacent teeth and dimensions and topography of the papillae lateral to implant‐supported single‐tooth restorations.Material and methodsA total of 32 subjects with a single implant‐supported restoration in the esthetic zone of the maxilla were consecutively selected for the study. Soft and hard tissues at the proximal sites of the restoration were evaluated by the use of clinical, photographic, diagnostic cast, and radiographic assessments. A questionnaire was used for assessment of the patients’ satisfaction with the esthetic outcome of the restorations. Potential factors influencing the papilla level and the presence of a complete papilla fill were investigated with generalized estimation equations (GEE) analysis.ResultsThe bone level at the adjacent tooth significantly influenced the papilla level (P < 0.001). The distance between the contact point and the bone level at the adjacent tooth was significantly shorter for “complete” (4.3 mm) papillae than that for “deficient” papillae (5.7 mm) (P < 0.001). The GEE logistic model revealed that the chance of a complete papilla fill improved with increased facio‐lingual thickness of the papilla (P = 0.004) and decreased distance between the contact point and the bone level at the tooth (P = 0.004). The self‐reported satisfaction with the esthetic appearance of the implant‐born restoration was not significantly different between patients with “complete” and “deficient” papillae.ConclusionThe probability of a complete papilla fill was significantly affected by the facio‐lingual dimension of the papilla base and the distance between the contact point between the crowns and the bone level at the tooth.

Published: February 2012

AbstractAimBone harvesting from the anterior nasal spine (ANS) is frequently used to correct peri‐implant bone defects, particularly during implant placement in the anterior maxilla. However, many clinicians are concerned about the postoperative effect of removing the ANS on the nasal outline, as the ANS is integral to supporting the nose. This study aimed to describe the technique of ANS bone grafting and to investigate postoperative effects of bone harvesting from the ANS on the overall nasal shape.Material and methodsFifteen patients with single maxillary first incisal rehabilitation using dental implant were enrolled in this prospective clinical study. Simply by extending the subperiosteal dissection in the same surgical field without additional local anesthesia, a bone block of about 0.25–0.5 ml could be harvested from the ANS. Nose width (NW), nasolabial angle (NLA), and nasal tip depth (NTD) were measured and analyzed by lateral and frontal photographs taken preoperatively (T0), and at postoperative 1 week (T1), 3 months (T2), and 6 months (T3). Postoperative complications were also recorded.ResultsA significant increase in NW and decrease in both NLA and NTD were found at T1 (P < 0.05). At T3, NW, NLA and NTD returned to preoperative measurements at T0 without major complications.ConclusionsThe ANS could be an effective and easily accessible intraoral source for autologous bone. Despite acute soft tissue swelling, the net postoperative effects of removing the ANS on the overall nasal shape, including on nasal tip collapse or widening of the nose base, were negligible.
Pseudocystic dermatofibrosarcoma protuberans: report of two cases and demonstration of COL1A1‐PDGFB rearrangement

Published: February 2012

We report two unique cases of dermatofibrosarcoma protuberans (DFSP) that included a pseudocystic component. Molecular analysis of one of the cases showed a characteristic COL1A1‐PDGFB rearrangement in both the main tumor and also in the cells lining the pseudocystic portion of the tumor, confirming the diagnosis and indicating that the lining represented a component of the proliferation. It is important to raise awareness of this rare variant within the varied spectrum of DFSP.Shvartsbeyn M, Lazar AJF, Lopez‐Terrada D, Meehan SA.

Published: February 2012

Introduction: Sentinel lymph node biopsy (SLNB) is a controversial but frequently used adjunct to wide excision of difficult‐to‐diagnose melanocytic proliferations of childhood. We herein report our institutional experience with SLNB in pediatric patients with these lesions, hereafter referred to as ‘atypical melanocytic proliferations'.Methods: Our prospectively collected melanoma database was queried for patients ≤21 years of age status post‐SLNB for a diagnosis of atypical melanocytic proliferation in which the diagnosis of melanoma ≥1 mm in depth was considered in the differential diagnosis by one or more expert dermatopathologists and for which no diagnostic consensus could be reached.Results: Of 24 patients identified over 17 years, 7 patients (29%) had a positive sentinel lymph node (SLN). Six SLN‐positive patients underwent complete lymph node dissection, with one (14%) having additional nodal involvement identified. With a median follow‐up of 4.1 years (range < 0.1 to 14.8 years), all patients showed no evidence of disease.Conclusions: Despite a significant rate of identification of melanocytes in SLNs of children with atypical melanocytic proliferations, survival appears favorable and controversy surrounding the significance of nodal involvement remains. Further studies with larger numbers of patients and long‐term follow‐up are needed before the true prognostic value of SLNB in this setting can be determined.Mills OL, Marzban S, Zager JS, Sondak VK, Messina JL.

ABSTRACTWe hypothesized that gene expression in placenta and umbilical vessels are affected by intrauterine environment and some of the expression in umbilical vessels originating from the fetus could reflect fetal condition of these complicated pregnancies. Expression of angiogenesis‐related factors and inflammatory cytokines were examined in placenta and umbilical vessels to clarify the effects of intrauterine environment of pregnancies complicated by preeclampsia and chorioamnionitis/funisitis. Forty‐six preterm cesarean section deliveries were classified into three groups based on maternal condition during prenatal monitoring: preeclampsia (PE) (n = 11), chorioamnionitis/funisitis (CAM) (n = 8), and preterm control (PC) (n = 27). Angiogenesis‐related factors and inflammatory cytokines in placentas, umbilical arteries and umbilical veins were analyzed by RT‐PCR and immunohistochemistry. We demonstrated that Ang‐2, Tie‐2, and Dll4 increase in the placentas of PE compared to PC for the first time, and we confirmed the findings of previous reports showing the high expression of HIF‐1α, sFlt‐1, endoglin, leptin, and AT1R. Expression of angiogenesis‐related factors, including HIF‐1α, VEGF, angiopoietin, and TGF‐β systems, and inflammatory cytokines, such as TNF‐α and IL‐6, increased in umbilical vessels of PE. Umbilical veins of CAM showed a higher Dll4 level than did PC. In preeclampsia, abnormal expressions of angiogenesis‐related factors related to lifestyle diseases in adulthood were seen in the placenta and umbilical vessels as compared to PC. Chorioamnionitis/funisitis showed only upregulation of DII4 in umbilical veins.
Kinematic analysis of maximal movement initiation in Greyhounds
Authors: Angle TC , Gillette RL , Weimar WH 
Published: February 2012

Background  Sprinting, jumping, stopping, turning and movement initiation produce the highest forces and largest ranges of motion in the canine gait, yet very little is known about them.Objective  The purpose of this study was to develop a general kinematic sequencing of maximal movement initiation of Greyhounds using joint angles and a segmental diagram.Design  Seven Greyhounds conducted maximal movement initiation trials on a vegetated surface by chasing a lure. A high‐speed kinematic analysis was conducted to evaluate joint angles (cervical, shoulder, elbow, carpus, hip, stifle and tarsus).Results  A sequence of the movement was developed and included a kinematic description at seven events: (1) standing, (2) set position, (3) front paw touch down, (4) rear paw take‐off, (5) front paw take‐off, (6) rear paw touchdown and (7) second front paw touchdown. In addition, canine segmental figures were generated for each of the seven events for a visual reference of segmental alignment.Conclusions  Sequencing provides an understanding of movement initiation in Greyhounds. The kinematic data helps fill the void in the scientific literature with regard to movement initiation in a naturalistic environment.Clinical relevance  These values will help the veterinary community understand the kinematics of maximal movement initiation so that training, conditioning, diagnosis, treatment and rehabilitation can be precisely directed to achieve the goal of optimal performance and properly returning dogs to athletic, recreational or working activities.

AbstractUnderstanding how pathogens emerge is essential to bring disease‐causing agents under durable human control. Here, we used cross‐pathogenicity tests to investigate the changes in life‐history traits of the fungal pathogenVenturia inaequalisassociated with host‐tracking during the domestication of apple and subsequent host‐range expansion on the wild European crabapple (Malus sylvestris). Pathogenicity of 40 isolates collected in wild and domesticated ecosystems was assessed on the domesticated apple, its Central Asian main progenitor (M. sieversii) andM. sylvestris. Isolates from wild habitats in the centre of origin of the crop were not pathogenic on the domesticated apple and less aggressive than other isolates on their host of origin. Isolates from the agro‐ecosystem in Central Asia infected a higher proportion of plants with higher aggressiveness, on both the domesticated host and its progenitor. Isolates from the European crabapple were still able to cause disease on other species but were less aggressive and less frequently virulent on these hosts than their endemic populations. Our results suggest that the domestication of apple was associated with the acquisition of virulence in the pathogen following host‐tracking. The spread of the disease in the agro‐ecosystem would also have been accompanied by an increase in overall pathogenicity.
Altitudinal variation in the taxonomic composition of ground‐dwelling beetle assemblages in NW Patagonia, Argentina: environmental correlates at regional and local scales

Published: February 2012

Abstract. 1. Altitudinal gradients offer a unique scenario to elucidate how the increase in harsh climatic conditions towards the top of the mountain interacts with other environmental factors at regional and local scale to influence the spatial variation in local species composition and biodiversity maintenance. We analysed the altitudinal variation in the taxonomic composition of epigaeic beetle assemblages across five mountains in north‐western Patagonia (Argentina) to address whether substantial change in species composition was associated (i) at regional spatial scale, with changes in vegetation types, and the presence of dry and moist mountains, and (ii) at local spatial scale, with variation in temperature, plant cover and richness and several soil characteristics.2. We collected beetles using 486 pitfall traps arranged in fifty‐four 100‐m2grid plots of nine traps settled at about 100 m of altitude apart from each other, from the base to the summit of each mountain. We used multivariate analyses to identify beetle assemblages and to evaluate their association with environment.3. We identified different beetle assemblages, associated more with vegetation types rather than with mountains; indicator species showed higher degree of fidelity and specificity to vegetation types rather than to mountains. Local variation in temperature, plant cover and richness, and soil characteristics influence the variation in species composition.4. Our study suggests the existence of a regional beetle fauna that is shared across these mountains. Major regional changes in vegetation types and local variation in environment drive the variation in the species composition of beetle assemblages at these latitudes.

AbstractObjectives: To compare the outcomes of restorations placed by restorative function auxiliaries (RFAs) with those placed by dentists.Methods: Between July 1, 2007, and June 30, 2008, we matched 455 restorations placed by RFAs working at HealthPartners Dental Group with the same number placed by dentists. Restorations were matched by tooth number, American Dental Association procedure code, and patient age‐group.Results: Of 910 restorations, 17 (1.9 percent) had problems potentially related to the filling or crown placement during the first year. Problem rates were not significantly different (p = 0.33) for restorations placed by RFAs (1.3 percent, 6 of 455) and those placed by dentists (2.4 percent, 11 of 455).Conclusions: There was no significant difference in problem rates for restorations placed by RFAs versus those placed by dentists. This finding may free dentists to handle more difficult cases, alleviating some of the pressures of daily practice and meeting the need for improved access.
