Cost-effectiveness of patient navigation programs for stroke patients–A systematic review
Authors: Kass Benjamin , Dornquast Christina , Meisel Andreas , Holmberg Christine , Rieckmann Nina , Reinhold Thomas 
Published: October 2021

Objective
Stroke remains a leading cause of premature death, impairment and reduced quality of life. Its aftercare is performed by numerous different health care service providers, resulting in a high need for coordination. Personally delivered patient navigation (PN) is a promising approach for managing pathways through health care systems and for improving patient outcomes. Although PN in stroke care is evolving, no summarized information on its cost-effectiveness in stroke survivors is available. Hence, the aim of this systematic review is to analyze the level of evidence on the cost-effectiveness of PN for stroke survivors.

Methods
A systematic literature search without time limitations was carried out in PubMed, EMBASE, CENTRAL, CINAHL as well as PsycINFO and supplemented by a manual search. Randomized controlled trials published prior to April 2020 in English or German were considered eligible if any results regarding the cost-effectiveness of PN for stroke survivors were reported. The review was conducted according to PRISMA guidelines. Quality of included studies was assessed with the RoB2 tool. Main study characteristics and cost-effectiveness results were summarized and discussed.

Results
The search identified 1442 records, and two studies met the inclusion criteria. Quality of included studies was rated moderate and high. Programs, settings and cost-effectiveness results were heterogeneous, with one study showing a 90% probability of being cost-effective at a willingness to pay of $25600 per QALY (health/social care perspective) and the other showing similar QALYs and higher costs.

Conclusions
Since only two studies were eligible, this review reveals a large gap in knowledge regarding the cost-effectiveness of PN for stroke survivors. Furthermore, no conclusive statement about the cost-effectiveness can be made. Future attempts to evaluate PN for stroke survivors are necessary and should also involve cost-effectiveness issues.
Radiological correlates of vocal fold bowing as markers of Parkinson’s disease progression: A cross-sectional study utilizing dynamic laryngeal CT
Authors: Ma Andrew , Lau Kenneth K. , Thyagarajan Dominic 
Published: October 2021

Objective
To determine whether arytenoid cartilage position and dynamics change with advancing duration and severity (as graded by MDS-UPDRS part III scores) in Parkinson’s disease, in a cross-sectional study design, we performed laryngeal four-dimensional computed tomography (4D-CT) in people with Parkinson’s disease and controls.

Methods
31 people with Parkinson’s disease covering a range of disease duration and severity and 19 controls underwent laryngeal 4D-CT whilst repeatedly vocalizing. We measured on each CT volume the glottic area (GA), inter-arytenoid distance (IAD), IAD-Area index (IAI) and arytenoid cartilage velocity (av→).

Results
People with Parkinson’s disease had reductions in the mean/effective minimum IAD when compared to controls, while mean/effective minimum GA and mean/effective maximum IAI were increased. Arytenoid cartilage velocities showed no difference. On Spearman correlation analyses, advancing disease duration and severity of PD showed moderately strong and significant correlations with increasing mean/effective minimum GA, increasing mean/effective maximum IAI and decreasing effective minimum IAD. Linear mixed models which considered the effects of intra and inter-individual variation showed that both disease duration (b = -0.011, SEb = 0.053, 95% CI [-0.022, 0], t(27) = -2.10, p = 0.045) and severity (b = -0.069, SEb = 0.032, 95% CI [-0.14,-0.0039], t(27) = -2.17, p = 0.039) were significant predictors for IAD, and also for transformed values of the GA and IAI.

Conclusions
There are progressive alterations in phonatory posturing as Parkinson’s disease advances. The increases in GA despite reductions in IAD are concordant with prior observations of vocal fold bowing. Our study provides a basis for using laryngeal 4D-CT to assess disease progression in Parkinson’s disease.

Published: October 2021

Objective: The purpose of this in vitro study is to evaluate the effect of four finish line configurations and two cement types on the fracture resistance of zirconia copings. Material and Methods: Forty yttrium tetragonal zirconia polycrystals copings were manufactured on epoxy resin dies with four preparation designs: knife edge, chamfer, deep chamfer 0.5, 1 mm and shoulder 1 mm. The copings were cemented with two cement types (glass ionomer and resin cement); (n = 5). Two strain gauges were attached on each coping before they were vertically loaded till fracture with a universal testing machine. Data were analyzed by 2-way analysis of variance ANOVA (p < .05). Fractured specimens were examined for mode of failure with digital microscope. Results: Knife edge showed the highest mean fracture resistance (987.04 ± 94.18) followed by Chamfer (883.28 ± 205.42) followed by Shoulder (828.64 ± 227.79) and finally Deep chamfer finish line (767.66 ± 207.09) with no statistically significant difference. Resin cemented copings had higher mean Fracture resistance (911.76 ± 167.95) than glass ionomer cemented copings (821.55 ± 224.24) with no statistically significant difference. Knife edge had the highest strain mean values on the buccal (374.04 ± 195.43) and lingual (235.80 ± 103.46) surface. Shoulder finish line showed the lowest mean strain values on the buccal (127.47 ± 40.32) and lingual (68.35 ± 80.68) with no statistically significant difference. Resin cemented copings had higher buccal (295.05 ± 167.92) and lingual (197.38 ± 99.85) mean strain values than glass ionomer copings (149.14 ± 60.94) and (90.27 ± 55.62) with no statistically significant difference. Conclusion: Vertical knife edge finish line is a promising alternative and either adhesive or conventional cementation can be used with zirconia copings.

Enamel Deproteinization: Will It Save The Shear Bond Strength For The Sake Of Preventing White Spot Lesions?
Authors: Elhiny Omnia A. , El-Refai Dina A. 
Published: October 2021

Objective: This study attempted to investigate the effect of enamel deproteinization using citric acid, PEG 400 and NaOCL on the shear bond strength of orthodontic brackets to enamel using nano-silver modified resin for the prevention of white spot lesions. Material and Methods: 68 premolars were used in the study; nano-silver modified adhesive resin was used to bond orthodontic brackets to the enamel. Specimens were divided into 4 groups according to the applied surface treatment before bonding. Group I (control): acid etching with 37% phosphoric acid. Group II: deproteinization using 5.25% sodium hypochlorite (NaOCl) before acid etching. Group III:deproteinization using 10% citric acid before acid etching. Group IV:deproteinization using 5% polyethylene glycol (PEG 400) before acid etching. The specimens were then thermo- cycled for 6000 cycles. They were examined for surface roughness, shear bond strength and using electron microscope. electron microscope Results: In both surface roughness and shear bond strength tests, Group III (citric acid) showed the highest values, followed by Group II (sodium hypochlorite); (p < 0.001). The least values were shown for Groups I (control) and IV (PEG 400), with no statistically significant difference between them (p = 0.948). SEM revealed etching pattern type 1 and 2 in the citric acid group while PEG 400 showed shallower micro- porosities. Conclusions: Deproteinization of enamel using either NaOCl or citric acid increased the bond strength of nano-sliver modified resin to enamel, with citric acid showing greater increase in bond strength. Deproteinization using PEG 400 did not increase the bond strength.

Published: October 2021

Objectives: To evaluate the awareness of medical emergencies among dental practitioners in three dental schools. Material and methods: The study group included 384 dental practitioners, including dental staff members, post-graduate students, and dental interns. These professionals were attending three dental educational institutions in Egypt. Two of them were governmental and one was a private school. The educational model is almost the same in most Egyptian dental schools. Results: The response rate was 100%. Most of the participants worked in private academia (44.16%) or practice (42.34%) and 65.20% of them were females. The participants recorded medical history and filled a form (91.17%, 80.52 % respectively) while only 41.82% obtained the vital signs. Among the participants, 48.57 % were confident about handling medical emergency and 74.29 % reported their capability of intramuscular injection while only 25.71 % for intravenous injection and 49.35% knew about emergency kits. Management knowledge of airway obstruction and prosthetic heart valve patients was reported by 80.27 % and 71.94 % respectively, while less percentage for activation of EMS, chest compression, CPR ratio, and infant rescue breathing. The mean preparedness percent score was 54.57% and it was inversely correlated to the years of experiences and directly correlated to the degree of confidence in their ability to manage the dental emergency. Conclusion: The current study results reflected a deficiency in the dental practitioner awareness about the medical emergency especially the practical part.

Assessing knowledge, practices, use and raising awareness of antibiotics and antibiotic resistance among dental patients before and after educational sessions
Authors: Farghaly Mahassen , Badran Amira , Keraa Khaled 
Published: October 2021

Abstract
Objectives: Education and awareness-raising are global health policy tools to modify public behavior towards antibiotic resistance. Considering the high frequency of antibiotic use and self-medication in Egypt, together with the lack of an awareness agenda, our objectives were to assess the knowledge and practices related to antibiotic use and resistance among patients attending dental clinics, and to evaluate the changes in knowledge following a specially designed one to one educational session. Methodology: A convenience sample of 310 dental patients participated in this study. A modified questionnaire was used to assess knowledge and practices related to antibiotic use and resistance. Second-year dental students were trained to administer the questionnaire and to use the educational materials they designed to raise awareness. Following the education session, patients completed another similar questionnaire to assess the changes in their knowledge. Results: Increasing awareness of antibiotic resistance can be an effective way to address the antibiotic resistance crisis. More than half of the participants (55.6%) did not know whether antibiotics treat diseases caused by bacterial or viral infections. The majority of participants (85.5%) had taken antibiotics during the last year, and (50.5%) of them had taken the same antibiotic more than once. Higher educational levels of the participants were significantly associated with a higher level of knowledge. Statistically significant increases in the percentages of correct answers to all questions were observed after the educational session. Conclusion: The one to one educational session is an effective approach to address the antibiotic resistance crisis.

Authors: Peña Bengoa Fernando , Ibañez Carlos , Ericles Paula , Meléndez Patricio , Cáceres Carolina 
Published: October 2021

Objective: To determine the prevalence of C-shaped canals in lower molars (first and second molars) in a Chilean subpopulation, and to identify root configuration and demographic characteristics using cone beam tomography. Materials and method: 912 molars (456 first and 456 second molars) resulting from the analysis of 228 mandibular CBCT scans (89 men and 139 women between 15 and 80 years old) were evaluated. Through panoramic reconstruction and axial tomographic sections, the root configuration was established, and the presence and type of C-shaped canal were classified, analyzing 5 levels along the root canal. Data were statistically analyzed with a 5% significance level. Results: Of the 912 molars analyzed, 69 were classified as C-shaped (7.57%), constituting 65.72% of those molars that presented fused roots. 100% of this configuration of canals was observed in lower second molars, presenting a higher prevalence in women (n = 49, 71.01%). 40.82% of the cases that presented a C-shaped configuration manifested bilaterally. The most frequent C-shaped canal configuration was C3 (n = 347, 66.10%), according to Melton's classification. Conclusion: The C-shaped canals in the studied population were observed entirely in lower second molars, showing a clear predilection for the female sex and a high rate of bilaterality.

Risk factors of complications subsequent third molar extractions: A prospective cohort study
Authors: Ali Dena 
Published: October 2021

Objective: The aim of this study was to determine the complications that were associated with the surgical removal of third molars (M3s), and to assess the association of patient, anatomic, and surgical risk factors with the postoperative complications of surgically removed impacted M3s. Material and Methods: This study was a cohort prospective study conducted on patients, aged 17 and older, admitted to the oral and maxillofacial surgery clinic. All patients who needed 1 or more extractions were included and totalled 268 patients with 314 extracted teeth. Risk factors were divided into patient factors, anatomic factors and surgical factors. The postoperative complication variables mainly included: pain, alveolar osteitis, infection, bleeding, swelling, trismus. Statistical analysis used: Chi-square test was used for the bivariate analyses while Pearson correlation coefficient (1- tailed) test was used for the purpose of determining the association between the study variables. The significance of associations was considered statistically significant at P < 0.05. Results: Patients aged of 25 years and above experienced more complications, 39 (88.6%). With respect to gender, females experienced more complications, 29 (65.9%). Mandibular M3s had more complications than maxillary M3s, 34 (8.0%), followed by distoangular inclined M3s, 23 (52.3%), and last was full bony impaction, 13 (29.5%). Pain was the most frequent complication, 18 (40.9%), followed by alveolar osteitis 12 (27.3%). Conclusion: The results indicated that the most frequently complications were pain, infection, alveolar osteitis. These complications were associated with common risk factors such as age, gender, medical history, M3 angulation, impaction level, bone removal, tooth sectioning, and number of M3 removed per session.

This study aimed to evaluate the association between life quality and the work capacity of nursing professionals in a public hospital of the public health system. A cross-sectional, quantitative study with the participation of 115 nursing professionals. The study method used the WHOQOL-brief questionnaire, the Work Capacity Index questionnaire, and a sociodemographic and occupational questionnaire. The data were analyzed through descriptive and inferential statistics, where values of p≤ 0.05 were considered significant. In terms of life quality, the domains that presented higher averages were for psychological 70.0±14.5 and social relations 70.8±19.8, with the physical domain reaching 64.4±11.9 and the environment at 57.7±13.6. The average score from the Work Capacity Index was 40.3±6.1; median: 42; IQR: 37.0-45.0), with a predominance of good and excellent for work capacity. Work capacity was increased for being male (β=3.99; p=0.016) and negatively associated to age (β=-0.31; p<0.001). In conclusion, it is verified that there is a positive correlation between the capacity for work and the evaluation of the quality of life, but it is emphasized that the sociodemographic and occupational characteristics lead the nursing professional to present a work capacity reduction, which generates alterations in the perception of life quality.
Effect of laser beam truncation (pinhole), (ordered) dithering, and jitter on residual smoothness after poly(methyl methacrylate) ablations, using a close-to-Gaussian beam profile
Authors: Verma Shwetabh , Hesser Juergen , Arba-Mosquera Samuel 
Published: October 2021

AbstractSmoother surfaces after laser vision correction have been widely accepted as a factor for improving visual recovery regardless of the used technique (PRK, LASIK, or even SMILE). We tested the impact of laser beam truncation, dithering (expressing a continuous profile on a basis of lower resolution causing pixels to round up/down the number of pulses to be placed), and jitter (a controlled random noise (up to ±20 µm in either direction) added to the theoretical scanner positions) on residual smoothness after Poly(methyl methacrylate) (PMMA) ablations, using a close-to-Gaussian beam profile. A modified SCHWIND AMARIS system has been used providing a beam profile with the following characteristics: close-to-Gaussian beam profile with full width at half maximum (FWHM) of 540 µm, 1050 Hz. Laser parameters have been optimized followingInvest. Ophthalmol. Vis. Sci., vol. 58, no. 4, pp. 2021–2037, 2017, the pulse energy has been optimized followingBiomed. Opt. Expressvol. 4, pp. 1422–1433, 2013. For the PMMA ablations, two configurations (with a 0.7 mm pinhole and 0.75 mJ and without pinhole and 0.9 mJ (for fluences of 329 mJ/cm2and 317 mJ/cm2and corneal spot volumes of 174 and 188 pl)) were considered, along with two types of lattices (with and without ordered dithering to select the optimum pulse positions), and two types of spot placement (with and without jitter). Real ablations on PMMA (ranging from −12D to +6D with and without astigmatism of up to 3D) completed the study setup. The effect of the 2 × 2 × 2 different configurations was analyzed based on the roughness in ablation estimated from the root mean square error in ablation. Truncation of the beam is negatively associated to a higher level of residual roughness; ordered dithering to select the optimum pulse positions is positively associated to a lower level of residual roughness; jitter is negatively associated to a higher level of residual roughness. The effect of dithering was the largest, followed by truncation, and jitter had the lowest impact on results. So that: Dithering approaches help to further minimize residual roughness after ablation; minimum (or no) truncation of the beam is essential to minimize residual roughness after ablation; and jitter shall be avoided to minimize residual roughness after ablation. The proposed model can be used for optimization of laser systems used for ablation processes at relatively low cost and would directly improve the quality of results. Minimum (or no) truncation of the beam is essential to minimize residual roughness after ablation. Ordered dithering without jitter helps to further minimize residual roughness after ablation. Other more complex dithering approaches may further contribute to minimize residual roughness after ablation.
Literaturausstellungen als Textedition
Authors: Gfrereis Heike 
Published: October 2021

Abstract
Literary exhibitions edit texts in their material aggregate states along with their material resistances and transitions and in a literary field which includes epi- and paratexts of all kinds. Texts, epi- and paratexts become ‘poetic things’ in an exhibition, in which production and reception merge. In this way, literary exhibitions can expand the traditional text-genetic edition. This is explained using the examples of exhibitions of the German Literature Archive / Museum of Modern Literature Marbach.
Tiefenbohrungen in den musikwissenschaftlichen Werk- und Autorschaftsbegriff mit digitalen Werkzeugen
Authors: Martensen Karin 
Published: October 2021

Abstract
The concept of work and authorship have long been the subject of intense reflection in historical musicology. Edition projects deal with composers and their work process and have developed new approaches for this purpose. Against the background of the question of where the ‘text’ to be edited actually ends, this paper discusses the possibilities of making director’s piano score (Regieklavierauszug) digitally visible and thus interpretable (understood as a work ‘sui generis’). Furthermore, the creative process of all participants in the classical sound recording is considered in terms of its digital visibility. On the basis of my research data from the DFG project “The sound recording studio as a discoursive room” at the TU Berlin/Audiokommunikation (participant observation, interviews, transcripts of recording processes, evaluations with MaxQDA) I show that these creative processes in the collaborative interaction of artists and engineers can also be found in classical music. By evaluating these (and other) materials with the help of MEI and TEI, new ways of ‘work’ and ‘authorship’ are also explored in this genre. Ultimately, this should also establish the sound recording as a ‘sui generis’ work.
Skill complementarity in production technology: New empirical evidence and implications
Authors: Stoyanov Andrey , Zubanov Nick 
Published: October 2021

Abstract
Danish manufacturing firm data reveal that 1) industries differ in within-firm worker skill (= wage) dispersion, and 2) within-firm skill dispersion positively correlates with firm productivity in industries with higher average skill dispersion. We argue that these patterns reflect technological differences between industries: firms in the “skill complementarity” industries profit from hiring similarly able workers, while the “skill substitutability” firms thrive on skill differences. Our study produces a robust, data-driven and theoretically validated classification of industries into the complementarity and substitutability groups, unveils hitherto unnoticed technological heterogeneity between industries within the same economy, and illustrates its importance through simulations.
