Open healing of contained and non-contained extraction sockets covered with a ribose cross-linked collagen membrane: a pilot study

Friedmann, Anton,Meskeleviciene, Viktorija,Yildiz, Mehmet Selim,Gotz, Werner,Park, Jung-Chul,Fischer, Kai R. Korean Academy of Periodontology 2020 Journal of Periodontal & Implant Science Vol.50 No.6

Purpose: This study investigated whether the placement of ribose cross-linked collagen (RCLC) membranes without primary soft tissue closure predictably resulted in sufficient alveolar ridge preservation in contained and non-contained extraction sockets. Methods: Membranes were positioned across extraction sockets, undermining full-thickness flaps, and the gingival margins were fixed by double-interrupted sutures without crossed horizontal mattress sutures for 1 week. In non-contained sockets, a bone substitute was used to support the membrane within the bony envelope. Radiographs and clinical images obtained 4 months later were analyzed by ImageJ software using non-parametric tests. Results: In 18 patients, 20 extraction sockets healed uneventfully and all sites received standard-diameter implants (4.1, 4.8, or 5.0 mm) without additional bone augmentation. Soft tissues and the muco-gingival border were well maintained. A retrospective analysis of X-rays and clinical photographs showed non-significant shrinkage in the vertical and horizontal dimensions (P=0.575 and P=0.444, respectively). The new bone contained vital bone cells embedded in mineralized tissues. Conclusions: Within the limitations of this pilot study, open healing of RCLC membranes may result in sufficient bone volume for implant placement without additional bone augmentation in contained and non-contained extraction sockets.

WHY CONSUMERS BUY “PRODUCTS” WHOSE ADVERTISEMENTS ARE OFFENSIVE?

Enav Friedmann 글로벌지식마케팅경영학회 2018 Global Marketing Conference Vol.2018 No.07

Offensive ads that reinforce stereotypes and disparage a group of people have been mainly posited as having a negative effect on purchase intentions of consumers. However, this purported negative effect on sales of offensive brands is incongruent with the growing trend of offensive advertising. In this paper, we demonstrated that offensive ads have a positive sales effect over the long term in a series of experiments. Specifically, we showed that there is a larger increase of sales of the discriminated group than the nondiscriminated group, over time. This overall positive sales effect can be explained by the sleeper effect, where the offensive context is forgotten over time. and, by selfmotivations in accordance to the Compensatory Consumption Theory. In the long term, self-esteem was found to moderate the relationship between “identity with my group” and purchase intentions. For low self-esteem individuals, less identification with the group, is related to wanting to purchase the product. While for high self-esteem individual’s higher identification means higher purchase intentions. Practically, these findings showed how offensive ads reinforce stereotypes and can be effective when targeting low self-esteem individuals. Hopefully, this will raise new ethical problems, limiting the use of such ads.

Providing Reliable Prognosis to Patients with Gastric Cancer in the Era of Neoadjuvant Therapies: Comparison of AJCC Staging Schemata

Kim, Gina,Friedmann, Patricia,Solsky, Ian,Muscarella, Peter,McAuliffe, John,In, Haejin The Korean Gastric Cancer Association 2020 Journal of gastric cancer Vol.20 No.4

Purpose: Patients with gastric cancer who receive neoadjuvant therapy are staged before treatment (cStage) and after treatment (ypStage). We aimed to compare the prognostic reliability of cStage and ypStage, alone and in combination. Materials and Methods: Data for all patients who received neoadjuvant therapy followed by surgery for gastric adenocarcinoma from 2004 to 2015 were extracted from the National Cancer Database. Kaplan-Meier (KM)curves were used to model overall survival based on cStage alone, ypStage alone, cStage stratified by ypStage, and ypStage stratified by cStage. P-values were generated to summarize the differences in KM curves. The discriminatory power of survival prediction was examined using Harrell's C-statistics. Results: We included 8,977 patients in the analysis. As expected, increasing cStage and ypStage were associated with worse survival. The discriminatory prognostic power provided by cStage was poor (C-statistic 0.548), while that provided by ypStage was moderate (C-statistic 0.634). Within each cStage, the addition of ypStage information significantly altered the prognosis (P<0.0001 within cStages I-IV). However, for each ypStage, the addition of cStage information generally did not alter the prognosis (P=0.2874, 0.027, 0.061, 0.049, and 0.007 within ypStages 0-IV, respectively). The discriminatory prognostic power provided by the combination of cStage and ypStage was similar to that of ypStage alone (C-statistic 0.636 vs. 0.634). Conclusions: The cStage is unreliable for prognosis, and ypStage is moderately reliable. Combining cStage and ypStage does not improve the discriminatory prognostic power provided by ypStage alone. A ypStage-based prognosis is minimally affected by the initial cStage.

Changes in Depressive Symptoms in Spouses of Post Myocardial Infarction Patients

Heesook Son,Erika Friedmann,Sue A. Thomas 한국간호과학회 2012 Asian Nursing Research Vol.6 No.4

Purpose: To identify parsimonious models for changes in depression in spouses of post myocardial infarction (MI) patients over 2 years based on the biopsychosocial model. Methods: A total of 442 community living patients who had experienced an MI and their spouses were included for analysis. Patients and spouses completed psychosocial assessments at baseline, 1 year, and 2 years after enrollment in the Patients’ and Families’ Psychological Response to Home Automated External Defibrillator Trial. Linear mixed models were used for testing hypotheses. Results: A total of 15.2% (baseline), 11.5% (1-year follow up), and 8.1% (2-year follow up) of spouses were depressed. Spouse biological factors did not influence changes in depression.Amongall spouses, twogroups of spouses showed increased depression over time: spouses with lower baseline depression scores (p < .001), and spouses of patients who had higher baseline depression scores (p = .001). Among psychologically distressed (anxious or depressed) spouses, three groups of spouses showed increased depression over time: spouses who had lower baseline depression scores (p < .001), spouses who had more social support at baseline (p = .023), and spouses of patientswho had higher baseline depression scores (p < .001). Conclusion: Spouse and patient baseline depression significantly predicted changes in depression for all spouses and psychologically distressed spouses. Among psychologically distressed spouses, higher baseline social support predicted higher depression scores over time. This study is an important step in understanding longitudinal changes in the psychological status of spouses ofMI patients for evaluating the need for interventions. It is crucial that patient couples’ psychosocial factors are continuously assessed.

Vibration-based structural health monitoring for offshore wind turbines – Experimental validation of stochastic subspace algorithms

Peter Kraemer,Herbert Friedmann 한국풍공학회 2015 Wind and Structures, An International Journal (WAS Vol.21 No.6

The efficiency of wind turbines (WT) is primarily reflected in their ability to generate electricity at any time. Downtimes of WTs due to “conventional” inspections are cost-intensive and undesirable for investors. For this reason, there is a need for structural health monitoring (SHM) systems, to enable service and maintenance on demand and to increase the inspection intervals. In general, monitoring increases the cost effectiveness of WTs. This publication concentrates on the application of two vibration-based SHM algorithms for stability and structural change monitoring of offshore WTs. Only data driven, output-only algorithms based on stochastic subspace identification (SSI) in time domain are considered. The centerpiece of this paper deals with the rough mathematical description of the dynamic behavior of offshore WTs and with the basic presentation of stochastic subspace-based algorithms and their application to these structures. Due to the early stage of the industrial application of SHM on offshore WT on the one side and the required confidentiality to the plant manufacturer and operator on the other side, up to now it is not possible to analyze different isolated structural damages resp. changes in a systematic manner, directly by means of in-situ measurement and to make these “acknowledgements” publicly available. For this reason, the sensitivity of the methods for monitoring purposes are demonstrated through their application on long time measurements from a 1:10 large scale test rig of an offshore WT under different conditions: undamaged, different levels of loosened bolt connections between tower parts, different levels of fouling, scouring and structure inclination. The limitation and further requirements for the approaches and their applicability on real foundations are discussed along the paper.

Mindfulness based intervention with an attentional comparison group in at risk young adolescents: a pilot randomized controlled trial

Kristen E Rawlett,Erika Friedmann,Sue A. Thomas 한국한의학연구원 2019 Integrative Medicine Research Vol.8 No.2

Background: Risky behaviors are related to poor outcomes among young adolescents. This study piloted a mindfulness based intervention, Learning 2 Breath Mindfulness Curriculum, focusing on the feasibility of programming and intervention effects on coping, affect, and trait mindfulness among at-risk adolescents. Further, the mindfulness based intervention was compared to an attention intervention. Methods: Sixth-grade level female students in a boarding school for at-risk youth randomly allocated to either the mindfulness intervention (n = 12) or an attention intervention (n = 11) for six weeks. Outcomes (i.e., primary coping, positive affect, and trait mindfulness) were assessed before and after the interventions. Results: Intervention groups did not differ in demographics or outcomes at baseline. Twenty-two of 23 (95.7%) registered participants attended all of the sessions. Participants completed 86.4% of study tools. Separate repeated measures ANOVAs revealed no significant interactions among group and time for primary coping, positive affect, or mindfulness. However, positive affect did increase [F(1, 17) = 10.675, p = 0.005, partial η2 = 0.39] over time for both groups and there was a slight increase in trait mindfulness over time (although not statistically significant; p = 0.095, partial η2 = 0.155]). Primary coping did not change with time. Conclusion: The mindfulness intervention utilized in the present study exhibited feasibility in this population. Although preliminary, mindfulness based interventions may contribute to positive affect among at-risk youth in a boarding school. Limitations and future directions are discussed.

DESIGNER AND CONSUMER PERCEPTIONS OF PREMIUM AND LUXURY: A SOCIAL CONSTRUCTIONIST ANALYSIS

Yael Pedro,Enav Friedmann 글로벌지식마케팅경영학회 2023 Global Marketing Conference Vol.2023 No.07

The social constructionist theory of art states that the value of art and luxury brand design is constructed by social interactions. It distinguishes between an independent reality and a socially constructed reality, in which meanings can differ. However, research on luxury fashion brands mainly focuses on consumers' reality and rarely examines the topic through a social constructionist lens. This paper looks at the impact of worldwide luxury fashion designers’ reality on consumers’ reality” when evaluating the brand. Three studies investigated how consumers and designers perceive premium and luxury brand design.
