ABSTRACT Introduction Hypocalcemia and permanent hypoparathyroidism are important outcome measures after total thyroidectomy. The aim of this article is to identify and highlight the wide variation in the adequacy/definition of these complications as reported in the surgical literature. Methods Nineteen journal articles (2008) on complications of thyroidectomy and 17 journal articles (2002) on ‘prediction’ of postthyroidectomy hypocalcemia derived from a PubMed search were reviewed. Results Only 21% of studies of describing outcome and complications of thyroidectomy defined hypocalcemia, temporary/permanent hypoparathyroidism. 47% of studies on the early prediction of hypocalcemia failed to quote their normal range of serum calcium. When stated, the biochemical definition of hypocalcemia varied from 1.8 to 2.12 mmol/l. There is no consistent definition of post-thyroidectomy hypoparathyroidism. Conclusion There is no consensus apparent on literature review as to what constitutes post-thyroidectomy hypocalcemia and hypoparathyroidism. The need to benchmark and define appropriate outcome measures of thyroid surgery demands that this deficit is addressed.

Individual differences are considered one of the main factors in language learning. This article begins by presenting the definition of individual differences and identifying the possible individual differences that may affect the L2 learning process are. Based on the literature review, shows that there are eight (8) major individual differences to be found as salient features in the L2 learning process. A brief overview of these eight (8) individual differences is provided, supported by the literature review of 20 journal articles. This journal article used grounded theory design as a method in identifying the relationship of the following individual differences in the L2 learning process. According to the results, although there is a growth in the study of individual differences that affects the L2 learning process, there is still much work to be done and much more investigation is required.

The importance of innovation is widely considered to be of peak importance for today´s enterprises. However, the understanding of one key element leading towards innovation seems to be neglected in scientific research: The innovative work behavior of individuals. Since Scott and Bruce investigated the determinants and introduced a path model of individual innovative work behavior twenty years ago (Scott and Bruce, 1994) much time has passed. New and upcoming trends in management, society and culture therefor could not be considered but influence the concept. This conceptual literature review therefor identifies, evaluates, aggregates and classifies the developments and trends from 2020 and 2021 regarding innovative work behavior. This study analyzed 41 journal articles, which further cited 3,609 publications as references, in EBSCO and Elsevier. The focus of the literature review was studies published in 2020 and 2021 and analyses that covered the topic of individual innovative behavior. The defined research objectives were framed by setting conceptual boundaries. Data was collected by using inclusion/exclusion criteria to then validate and manually review the research results. The results of this review suggest that firstly there is a change visible of the definition of the term itself, which has also influenced the scales being used to be reviewed or shifting. In addition the review shows how changes in working and managing enterprises effect innovative work behavior. They can be grouped into the three areas: role and impact of culture, societal trends and new management trends. Thus the effects of mindfulness, transformational leadership, usage of social media, or corporate social responsibility on innovative work behavior are better understood. This conceptual literature research connects and aggregates the various tendencies and supports new measurement models introduced which might help to identify possible causes of these discrepancies and provide direction for further research. Thereby this conceptual literature review thus sheds light on what otherwise seems to be a familiar concept.

This article is devoted to the main problems of assessing the competitiveness of enterprises. The concept of competitive advantage is central in strategic management studies. Firm-level competitiveness is a relative concept based on the comparison; the comparison could be between the main factors or variables to measure the level of development between them. The notion of competitiveness lies at the heart of business strategy development, where it depends on several factors which are interrelated and cannot be looked at into isolation. Some of these indicators can be considered at different levels of aggregation: firm, industry, regional, local, national or sectoral where it seems that the competitiveness notion should be rather defined as a set of characteristics of one object with respect to comparable objects “benchmarks” in the market. Based on the definition of the main characteristics of the competitiveness of the enterprise, the authors proposed an original definition of this term. A systemic literature review approach named as longitudinal literature review has been adopted in this article to target the most crucial indicator for measuring competitiveness. The data has been collected from articles with the highest index journal articles in Scopus and Web of Science database. All the journal articles that have been targeted ranked as Q1 quartiles which means it is in the top 25 % of highest impact factor and highest impact index. For eliminating the most effective competitiveness indicators, the authors have used the Vos-viewer software to analyze more than 77972 publications Based on the content analysis, the authors proposed the system of indicators of enterprise competitiveness, consisting of four indicators (net profit growth, staff turnover, profit margin, return on investment), found in more than 50% of scientific articles. The authors propose methodological bases for dynamic assessment of the competitiveness of the enterprise, which are to compare changes in the competitiveness of the object of study with changes in industry averages. Using of this technique will measure the impact of managerial decisions on the competitiveness of the enterprise.

Abstract Background Horner syndrome (HS), mainly characterized by symptoms including ptosis, miosis, and anhidrosis on the affected face, is a condition that is well documented but rarely reported as a postoperative complication of thyroidectomy, particularly in endoscopic thyroid surgery (ETS). We hereby report a case of HS due to ETS with a brief literature review on this topic. Case presentation A 31-year-old female was admitted to our hospital with an unexpected physical examination finding of two thyroid nodules that were hypoechoic, had an irregular shape, and exhibited calcification. Subsequently, the results of a fine-needle aspiration (FNA) biopsy from the thyroid nodules and BRAFV600E mutation further confirmed the malignancy of these nodules. Thus, total thyroidectomy combined with central lymph node dissection (CLND) by ETS via the bilateral axillo-breast approach was performed on this patient. Histology confirmed the diagnosis of papillary thyroid microcarcinoma (PTMC) concurrent with Hashimoto’s thyroiditis (HT). However, this patient developed HS with ptosis in her left eye on postoperative day 3. All symptoms gradually resolved before the 3-month follow-up. Conclusion HS subsequent to ETS is a rare complication. Thus, standardized and appropriate operative procedures, as well as subtle manipulation, are essential in preventing and reducing the occurrence of HS. In addition, the early diagnosis and management of this rare complication are also important for a favorable outcome.

This work aims to reorganize theoretical and empirical research on smart mobility through the systematic literature review approach. The research goal is to reach an extended and shared definition of smart mobility using the cluster analysis. The article provides a summary of the state of the art that can have broader impacts in determining new angles for approaching research. In particular, the results will be a reference for future quantitative developments for the authors who are working on the construction of a territorial measurement model of the smartness degree, helping them in identifying performance indicators consistent with the definition proposed.

Abstract Background Scaphoid nonunion can lead to carpal collapse and osteoarthritis, a painfully debilitating problem. Bone morphogenetic protein (BMP) has been successfully implemented to augment bone healing in other circumstances, but its use in scaphoid nonunion has yielded conflicting results. Case Description The purpose of this study is to assess the outcomes and complications of scaphoid nonunion treated surgically with BMP. Literature Review A literature review of all available journal articles citing the use of BMP in scaphoid nonunion surgery from 2002 to 2019 was conducted. We included studies that used BMP as an adjunct to surgical treatment for scaphoid nonunions in both the primary and revision settings with computed tomography determination of union. Demographic information, dose of BMP, tobacco use, outcomes, and complications were recorded. A total of 21 cases were included from four different studies meeting inclusion criteria. Clinical Relevance The union rates were 90.5% overall, 100% for primary surgeries, and 77.8% for revision surgeries. Five patients (24%) experienced 11 complications, including four cases (19%) of heterotrophic ossification. Use of BMP in scaphoid nonunion surgery resulted in a 90.5% overall union rate but was also associated with complications such as heterotopic ossification. All included studies used BMP to augment bone graft, screw or wire fixation, or a combination of methods. The efficacy of BMP in scaphoid nonunion is unclear, and a sufficiently powered, randomized controlled trial is needed to determine optimal fixation methods, dosing, and morbidity of the use of BMP. Level of Evidence This is a Level IC, therapeutic interventional study.
