Authors: Claassen Kevin , Anjos Dominique Rodil dos , Kettschau Jan Patrick , Wrede Sammy Joelle Shirley , Broding Horst Christoph 
Published: May 2022

Abstract
Background
Against the background of e-government, it is discussed whether self-organization represents an independent component of digital leadership. Addressing this research question, the instrument "DigiFuehr" is being expanded to include the aspects of self-determination and coordination. The aim is to test the model quality of three adapted scales against the already established support-focusing version.
Methods
Based on an online survey of n = 422 employees at visual display unit workstations in German municipal administrations in April 2022, the original version of DigiFuehr as well as one reduced and two extended versions were validated considering their local and global model fit.
Results
All four scales show a good local fit with regard to internal consistency (Cronbach's α), discriminatory power and dimensionality. Only the scale extended by two items also offers a sufficient global fit and is thus most suitable as a predictor for psychological stress, work satisfaction and satisfaction with the professional exchange during homeworking.
Conclusions
With "DigiFuehr 2.0", an improved version of the original scale is available. Self-organization is not a component independent of the support dimension, but a further important indicator of a latent digital leadership culture. Neither should come at the expense of the other.

Abstract
Purpose Patient follow-up is an essential part of hospital management. With the advent of the information age, patient follow-up is expected to be replaced by Internet technology. This study constructed a gynecological chemotherapy patient cloud follow-up platform to evaluate its cost-effectiveness and patient feedback effect.Methods A total of 2538 patients were followed up using a cloud follow-up system between January and October 2021. Prior to this, 690 patients were followed up manually over telephonic calls. The patient characteristics, follow-up rate, patient satisfaction, and session duration in the cloud follow-up group and manual follow-up group were compared. In addition, the read rate of health education materials in the cloud follow-up group was analyzed.Results The general information (age, cancer stage, and disease category) and follow-up rate (cloud: 6957/7614, 91.4%; manual: 1869/2070, 90.3%; P=0.13) did not significantly differ between the two groups. The follow-up satisfaction of the cloud follow-up patients was significantly better than that of the manual follow-up group (cloud: 7192/7614, 94.5%; manual: 1532/2070, 74.0%; P＜0.001). The time spent on the follow-up of 100 patients in the cloud follow-up group was approximately 1.2 hours compared to 10.5 hours in the manual follow-up group. The read rate of health education materials in the cloud follow-up group was 72.9%.Conclusions The follow-up effect of the cloud follow-up group was not inferior to that of the manual follow-up group, and the cloud follow-up group was more in line with the prevention and control requirements of the post-epidemic era. Cloud follow-up can save medical resources, improve cost-effectiveness, provide sufficient health education resources for patients, and improve patient satisfaction.

Abstract
BACKGROUND: Lip-splitting approach for oncologic resection and defect reconstruction of tongue squamous cell carcinoma (TSCC) needs modification to avoid unfavorable aesthetic results. METHODS: Forty-three patients with TSCC underwent surgery using the modified submandibular mandibulotomy( MSMM) approach without lip-splitting and another matched 43 patients using lip-splitting mandibulotomy (LSM) approach were reviewed retrospectively. Clinical outcomes evaluation consisted of tumor exposure, resection margin, surgical morbidity, locoregional recurrence, survival status, scar scores and quality of life (QOL). RESULTS: All the tumors were en bolc removed by MSMM approach and LSM approach through combined intraoral routes with excellent tumor exposure and R0 resection margins. Tumor recurrence rates and swallowing, chewing, speech were similar in both groups. The MSMM approach was associated with significantly better facial appearance and recreation than LSM approach. CONCLUSION: The MSMM approach without lip-splitting is safe and effective, achieves better aesthetic results and QOL compared to LSM approach in patients with TSCC.

Abstract
Metasurfaces have recently realised many revolutionary applications such as metalenses, equation solvers, beam shapers, and holographic projection.1–4 However, the conventional metasurfaces are monotask due to their fixed dimensions. Therefore, realising multitask metasurfaces for applications such as beam steering, optical switches and meta-displays, which require fast and dynamic reconfigurability, has bottlenecked. To address this technological challenge, there has been a quest to enable tunability via mechanical tilting or stretching the samples, rotating the illumination angle or the incident light polarisation, use of chemical reactions, and others.5–8 However, most of these approaches still suffer from slow tuning rate, weak modulation, and bulky or non-solid state components. Here, we introduce electrically tunable metasurfaces that offer up to 9 folds surge in transmission, i.e. 90% transmission modulation depth, with switching time <625 µs, i.e. one order of magnitude faster than video frame rates. To realise such a breakthrough, we have driven the designed metasurface by <5 V spiked voltage, asymmetrically, for the first time in optoelectronics.

Abstract
The Brazilian scientific community has available a curricular information system called Lattes. The analysis in the area of scientific production is rapidly evolving as we have an increase in the number of publications combined with increasingly interdisciplinary sources of information. The Brazilian scientific community has available a database with curricular information called Lattes which contain information about academic and scientific achievements. There is a demand to carry out the search and retrieval of information from the Lattes curriculum in order to reduce the difficulties in exploring bibliometric data and to aid in the analysis of this information. This article uses textual data mining techniques, multidimensional projection techniques and visualization based on analysis of bibliometric data extracted from the Lattes platform. The results obtained were clusters of research groups that are related to each other and clusters of research groups that work with very different themes. These results can become a tool for visually exploring bibliometric data from the Lattes platform.

Published: May 2022

Abstract
BackgroundChest wall sinus with infection is a refractory disease caused by a variety of susceptible factors, and the treatment is still challenging.For clinically complex cases, although there are various surgical methods to choose from, it is still very difficult to achieve clinical cure,especially for patients with older age and many underlying diseases.Complete resection of chest wall sinus and application of repair and reconstruction technology may bring hope to refractory cases.Case presentationHerein,We report a case of a 67-year-old woman who had undergone breast cancer surgery and a history of multiple cycles of radiotherapy and chemotherapy.One year ago, she had a fistula in the left chest wall with yellow purulent fluid.After admission to our hospital, chest computed tomography (CT) showed the formation of the left chest wall sinus, accompanied by high-density images of the left clavicle, part of the ribs and part of the sternu.According to the patient's symptoms, signs and imaging examination, we preliminarily diagnosed the patient as chest wall sinus with infection and chronic osteomyelitis.Therefore, in the first-stage operation,the patient underwent left chest wall sinus resection, left partial rib resection, left partial clavicular resection and left partial sternal resection,After surgery, the wound surface was changed with gauze dressing with sensitive antibiotic solution every day until the wound surface was clean and new granulation was formed.In the second-stage operation, the wound surface was appropriately expanded, and the pedicled latissimus dorsi myocutaneous flap was transferred to the chest wall defect. Finally, the skin paddle was sutured without tension to the normal skin around the chest, and two drainage tubes were placed.Anti-infection, anti-spasm, anti-coagulation and other treatments were given after operation, and the survival of myocutaneous flap, wound healing and sinus disappearance were observed.ConclusionsThe application of pedicled latissimus dorsi myocutaneous flap in the treatment of intractable chronic chest wall sinus is an effective method. It does not change the shape of the thorax. The clinical effect is satisfactory in the near and medium term, which is worthy of clinical promotion.
Material point simulations as a basis for determining Johnson-Cook hardening parameters via instrumented scratch tests

Published: May 2022

Abstract
Scratch tests are a powerful and inexpensive tool for studying the mechanical properties of materials. The tests are typically applied for determining the deformation behavior of materials and serves as quality assessment method for measuring the adhesion and delamination properties of coatings. However, the extraction of quantitative material parameters using scratch tests remains elusive and, contrary to instrumented indentation or tensile testing, hardly any procedures are available so far for determining the hardening behavior of materials. Such a procedure is of enormous relevance, since it allows a non-destructive determination of the material parameters of constitutive models commonly used in computer simulations for thin films, coatings, or surface changes due to loading. In this work we rely on extensive computational simulations of scratch tests using a meshless Material Point Method for finding relationships between the scratch forces, the scratch topography, and the material parameters. The simulations are performed for two large groups of metals with Young’s moduli corresponding to steel and copper. Within each group, the yield stresses and hardening parameters are varied in order to cover the widest possible range of hardening behaviors. The results show that the scratch topography serves to narrow down the value of the yield stress, which can be alternatively determined using indentation. Once the yield stress is known, the hardening parameter can be unequivocally determined for a fixed hardening exponent via the scratch topography using a single scratch, or via the scratch forces using two scratches, provided that they are done at different normal loads.

Abstract
Background. In the absence of a gold-standard diagnostic modality for cellulitis, sterile inflammatory disorders may be misdiagnosed as cellulitis.Objective. To determine the utility of skin biopsy and tissue culture for the diagnosis and management of patients admitted with a diagnosis of cellulitis. Design. Pilot, single-blind parallel group randomized controlled clinical trial evaluating length of stay and antibiotic use in 56 patients with a primary diagnosis of cellulitis. Skin biopsy and tissue culture results were only reported in the intervention group. Corollary analysis of adipose tissue inflammation and structural changes in cellulitis. Results. Hospital length of stay showed the greatest opportunity for further study as a primary outcome (intervention: 4, IQR (2-6) vs control: 5 IQR (3-8) days; p = 0.124). In the corollary study, there were differentially expressed genes related to inflammation (CD74), macrophage characterization (CD14, MCP1, CD36) and extracellular matrix proteins (VEGFA, FGF1, FGFR1/3, TIMP1, COL12A1) in the adipose tissue of chronic cellulitis patients.Limitations. Limited number of participants.Conclusion. The study demonstrated that hospital length of stay and anti-pseudomonal antibiotic de-escalation are endpoints worth further study. The corollary study demonstrated multiple inflammatory and structural genes that are upregulated in this disease process.

Abstract
Background: The COVID-19 pandemic brought countless challenges to public health and highlighted the Brazilian health system vulnerabilities to face the emergency situation. In this article, we analyze data on COVID-19-related deaths in Brazil in 2020-21 to show the tragic consequences of the pandemic on the Brazilian population.Methods: The Mortality Information System and the Live Birth Information System were the main information sources. We used the population estimates in 2020-21 to calculate COVID-19 specific mortality rates by age and sex and educational level. Considering the total number of deaths in 2020-21, the COVID-19 proportional mortality (%) was estimated for each age group and sex. A graph of the daily deaths from January 2020 to December 2021 by sex was elaborated to show the temporal evolution of COVID-19 deaths in Brazil. In addition, four indicators related to COVID-19 mortality were estimated: infant mortality rate; maternal mortality ratio (MMR); number of orphans due to mother's death; average number of years lost.Results: The overall COVID-19 mortality rate was 14.8 (/10,000). The mortality rates increase with age and show a decreasing gradient with higher schooling. Among illiterate people, the rate was 38.8/10,000, three times higher than those with college education. Male mortality was 31% higher than female mortality. COVID-19 deaths represented 19.1% of all deaths, with the highest proportions in the median age groups. The average number of years lost due to COVID-19 was 19 years. The MMR due to COVID-19 was 35.7 per 100,000 LB, representing 37.4% of the overall MMR. Regarding the number of orphans due to COVID-19, we estimated that 40,830 children under 18 years old lost their mothers during the pandemic, with an orphans' rate of 7.5/10,000 children aged 0-17 years. The pandemic peak occurred in March 2021, reaching almost 4,000 deaths per day, higher than the average number of deaths per day from all causes in 2019. Conclusions: The COVID-19 lethality rate in Brazil was 2.2%, twice the global lethality rate. The delay in adopting public health measures necessary to control the epidemic has exacerbated the spread of the disease, resulting in several avoidable deaths.

Published: May 2022

Abstract
Background Inflammatory myofibroblastic tumor (IMT), also known as an inflammatory pseudotumor, is a unique type of intermediate soft tissue tumor that commonly occurred in the lung. Its unclear etiology and cellular activity brought about the confusion not only in naming of it, but also in diagnosis and treatment. Case presentation We reported the case of an 18-year-old male student who suffered from shortness of breath, chest tightness and chest pain. Chest computed tomography scan showed a spherical neoplasm blocking left main stem bronchus. After fiberoptic bronchoscopy procedure, the results of histopathological and immunohistochemical analysis indicated an IMT. The targeted next generation sequencing based genomic profiling of the tumor using formalin-fixed and paraffin embedded tissue was performed and a EML4-ALK fusion was detected. The patient began to receive Crizotinib, a ALK tyrosine kinase inhibitor, at a dose of 250 mg twice daily orally. The patient has recovered well after the operation, and no recurrence or metastasis has been found after 12 months’ follow-up.Conclusion By means of the diagnosis and treatment of this case, the characteristics and therapies of IMT are illustrated. In addition, it also provides a reference for the therapeutic strategy of IMT in the future.

Abstract
Background: The recognition of patient-reported outcomes for oral cancer is important in improving patients’ quality of life. The aim of this study was to translate and validate the modified Sinhala version of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Oral Health Module (EORTC QLQ-OH15).Methods: A cross sectional study was conducted to validate the EORTC QLQ-OH15 that was modified after adding two questions to the original questionnaire. The two questions added were ‘difficulty in opening the mouth wide’ and ‘trouble with talking’ which affect oral health related quality of life (OHRQOL) of oral cancer patients receiving radiotherapy. The Sinhala translated modified EORTC QLQ-OH15 and the core questionnaire EORTC QLQ-C30 were self-completed by 85 adult oral cancer patients who received initial anti-cancer treatment with radiotherapy with or without chemotherapy.Face, consensual and content validity were examined by the appearance. Construct validity was confirmed by using factor analysis, multi-trait scaling analysis, and known group comparison. Reliability was assessed by internal consistency, test-retest reliability and intra class correlation coefficient. Responsiveness to change was assessed.Results: The majority of participants (58%) were aged 50-69 years and 84% were males. Nearly 32% had cancer of the anterior two thirds of the tongue. Of the sample, 66% received chemo radiotherapy. Thirteen items were included for the factor analysis. They were loaded for four factors. Three scales ‘Eating problem’, ‘Gum and Speech problem’ and ‘Soreness’ loaded with 5, 4 and 3 items respectively and single item ‘teeth’ to a one factor with the total variance explained was 72.74%.Mann–Whitney U tests for all three scales were statistically significant confirming the ability of the modified EORTC QLQ-OH15 to detect expected differences in OHRQOL in clinically different groups. Cronbach’s alpha for all the scales were more than 0.8. Wilcoxon Matched Paired Sign Rank Test showed highly significant results (p<0.05) for all three scales revealing high responsiveness. Conclusion: The modified Sinhala version of the EORTC QLQ-OH15 is a valid, reliable tool that can be used to measure OHRQOL in oral cancer patients who receive radiotherapy with or without chemotherapy.
