Abstract
Bilateral extensor tendon ruptures of the knee are not uncommon. However, simultaneous ruptures of the patellar tendon (PT) and contralateral quadriceps tendon (QT) are relatively rare injuries. These ruptures are frequently associated with chronic renal failure and minor trauma. However, they can occur spontaneously in healthy individuals. In this case report, a 43-year-old male with chronic renal failure who sustained bilateral extensor tendon ruptures (right knee: QT rupture, left knee: PT rupture) following an alternating current electrical shock was reported. To our knowledge, simultaneous quadriceps and contralateral patellar tendon rupture following an electric shock have not been reported yet. Etiology, mechanism of injury and treatment options of this rare injury are discussed together with a thorough literature review.

Abstract
Introduction. Bisphosphonates (BPs) represent the main therapy in patients with osteoporosis, although a long-term treatment can lead to atypical fractures.
Material and methods. We conducted a retrospective study between 2008 and 2017 and included 23 female patients with atypical femoral fractures (AFFs). The mean period of BPs therapy administration was 5.2 years. We included 7 subtrochanteric fractures and 18 femoral shaft fractures. Two of the total patients presented bilateral femoral fractures. 18 patients presented prodromal symptoms from 2 to 18 months before the diagnosis of fractures, all of them following low energy trauma. All the patients included in our study underwent surgery with intramedullary nail or gamma nail. The postoperative mean follow-up was 2 years. Results. Of all 23 female patients with a total of 25 fractures – 10 underwent osteosynthesis with gamma nail and 15 underwent osteosynthesis with intramedullary nail. From the total number of patients: 13 patients achieved complete union, 6 presented delayed union and 3 non-union (2 intramedullary nail and one gamma nail), whereas in one patient treated previously with gamma nail we observed implant failure.
Conclusion. The treatment of AFFs after BPs therapy administration represents a challenge for orthopaedic surgeons regarding both surgical technique and postoperative follow-up.

Authors: Depken Craig , Chiseni Chanda , Ita Ernest 
Published: June 2019

Abstract
We utilize two waves of the National Income Dynamics Study in South Africa to estimate the returns to education in 2010 and 2012. We find that during this time period the returns to education were approximately 18% per year of education and that the returns were higher for females relative to males and higher for those living in urban relative to rural areas. The policy implications include a suggestion to continue investment in educational infrastructure, especially in rural areas, so as to increase the returns to education in those areas.
Characteristics of Undeclared Work in Service Sector in Countries of South East Europe
Authors: Bejaković Predrag , Stefanov Ruslan 
Published: June 2019

Abstract
The undeclared work is a complex and multifaceted phenomenon that has been present in all countries, regardless of its social and political establishment. Notwithstanding, the empirical evidence suggests that informal economy is more prevalent in countries with lower levels of GDP. Furthermore, the informal economy is present in sectors with lower level of capital and higher level of labour intensity. Therefore, the theory and everyday experience imply that the informal economy is more widespread among the services than the goods sectors. This paper provides an overview on the informal work and unofficial economy in the services sector in the former socialist countries in South East Europe. For the reduction of undeclared activities, it is necessary to simplify the procedures for establishing small businesses, to stabilize the tax system, to ensure high tax morale and trust in society and towards institutions, and to decrease the state regulatory burden.

Research subject. This paper reports the results of a series of experiments carried out to study the mineral and geoche mical features of 10 Chelyabinsk meteorite fragments. In addition, these fragments were analysed in terms of their chemical composition.Materials and methods. The fragments under study were represented by light-grey granular rocks of the chondrite structure having either isometric or elongated shape. Their surface was largely covered with a black-brownish fusion crust with a thickness of approximately 1 mm. The petrogenic components of the meteorite and the content of rare elements were studied using the methods of chemical silicate analysis and ICP MS respectively. All measurements were carried out using an Agilent 7700x quadrupole mass spectrometer produced by the Agilent Technologies company. The composition of sulphides and metal particles was determined by electron probe microanalysis (PCMA) usinga JXA8200 microanalyzer (Jeol, Japan).Results. The chondri and cementing matrix are found to be primarily composed of olivine and orthopyroxene. The inter-chondruli matrixis shown to consist of a pyroxene-olivine aggregate with inclusions of plagioclase, apatite, fused glass and ore minerals (tenite, kamasite, troilite, rarely pyrrhotine, pentlandite, single grains of chromite and ilmenite). The concentration of the majority of rare and ore elements in the Chelyabinsk meteorite samples is established to be close to their average values for LL-chondrite. When normalizing to coaly chondrite, the substance of the meteorite fragments and the average LL-chondrite were closest to coaly chondrite in terms of the content of siderophile elements (Mo, Ni, Cr, Co, V and Cu). At the same time, the studied meteorite fragments are shown to contain a significantly lower (nearly by one order) concentration of chalcophyle elements (Zn, Pb and Sn) with regard to С1.Conclusion. A comparison of the obtained and published analytical data (ICP MS) has allowed us to make a conclusion on the geochemical heterogeneity of different meteorite remainst hat were scattered over a wide area of the Chelyabinsk Region. The acquired evidence suggests the differentiation of meteorite substance at early stages of the formation of terrestrial planets, which is likely to have occurred due to impact processes.

Published: June 2019

This research is an explanatory study of the learning experience of international students when they come to study at UK. Survey collected from both undergraduate and postgraduate students who are studying at the University of The West of Scotland (UWS). The survey consisted on many dimensions such as selection and admission, pre arrival activities, induction, orientation, teaching and learning and engagement. Our results provide some recommendations for academic staff and for international office at UWS. For academic staff, they should integrate the international dimension while they are designing their courses. They should implement interactive lectures and involve the international students into discussions. For staff who are working in the international office, they should attend training on how to deal with international students to be able to offer good service for them. They might ask for current international students to help in recruiting international students. Our study has a number of limitations that should be taken into account in future research. The focus on this study was on one university only. Future research should collet data from different universities to allow for comparisons. This is the first study to explore the whole experience of the international students. More research is needed to focus on each of the dimensions separately i.e induction, engagement, etc…
From Health Care to Population Health: Retooling Legal Structures for a New Paradigm
Authors: Williams Jackson 
Published: June 2019

ABSTRACT
As more Americans are burdened with chronic conditions, prominent health policy thought leaders urge a reorientation of our health care system from provision of episodic, reactive care to a “population health” focus. Some of the mechanisms proposed to achieve this would devolve certain responsibilities from physicians to other members of care teams. In particular, there is heightened interest in deploying lay health workers to reach out to the medically underserved. The Food and Drug Administration has initiated formal discussion of loosening regulatory constraints on the prescribing of medications used to treat chronic conditions. This article reviews recent efforts to transform care delivery and the regulatory barriers to realizing their full potential. It concludes that there are promising health interventions that could be implemented on a wider scale if legal barriers were lifted. It proposes a design for demonstration projects that would waive some regulatory requirements to permit testing of innovative population health models.

OBJECTIVEProlactinoma and nonfunctioning adenoma (NFA) are the most common sellar pathologies, and both can present with hyperprolactinemia. There are no definitive studies analyzing the relationship between the sizes of prolactinomas and NFAs and the serum prolactin level. Current guidelines for serum prolactin level cutoffs to distinguish between pathologies are suboptimal because they fail to consider the adenoma volume. In this study, the authors attempted to describe the relationship between serum prolactin level and prolactinoma volume. They also examined the predictive value that can be gained by considering tumor volume in differentiating prolactinoma from NFA and provide cutoff values based on a large sample of patients.METHODSA retrospective analysis of consecutive patients with prolactinomas (n = 76) and NFAs (n = 217) was performed. Patients were divided into groups based on adenoma volume, and the two pathologies were compared.RESULTSA strong correlation was found between prolactinoma volume and serum prolactin level (r = 0.831, p < 0.001). However, there was no significant correlation between NFA volume and serum prolactin level (r = −0.020, p = 0.773). Receiver operating characteristic curve analysis of three different adenoma volume groups was performed and resulted in different serum prolactin level cutoffs for each group. For group 1 (≤ 0.5 cm3), the most accurate cutoff was 43.65 μg/L (area under the curve [AUC] = 0.951); for group 2 (> 0.5 to 4 cm3), 60.05 μg/L (AUC = 0.949); and for group 3 (> 4 cm3), 248.15 μg/L (AUC = 1.0).CONCLUSIONSProlactinoma volume has a significant impact on serum prolactin level, whereas NFA volume does not. This finding indicates that the amount of prolactin-producing tissue is a more important factor regarding serum prolactin level than absolute adenoma volume. Hence, volume should be a determining factor to distinguish between prolactinoma and NFA prior to surgery. Current serum prolactin threshold level guidelines are suboptimal and cannot be generalized across all adenoma volumes.

OBJECTIVEThere is a need for real-time, intraoperative tissue identification technology in neurosurgery. Several solutions are under development for that purpose, but their adaptability for standard clinical use has been hindered by high cost and impracticality issues. The authors tested and preliminarily validated a method for brain tumor identification that is based on the analysis of diathermy smoke using differential mobility spectrometry (DMS).METHODSA DMS connected to a special smoke sampling system was used to discriminate brain tumors and control samples ex vivo in samples from 28 patients who had undergone neurosurgical operations. They included meningiomas (WHO grade I), pilocytic astrocytomas (grade I), other low-grade gliomas (grade II), glioblastomas (grade IV), CNS metastases, and hemorrhagic or traumatically damaged brain tissue as control samples. Original samples were cut into 694 smaller specimens in total.RESULTSAn overall classification accuracy (CA) of 50% (vs 14% by chance) was achieved in 7-class classification. The CA improved significantly (up to 83%) when the samples originally preserved in Tissue-Tek conservation medium were excluded from the analysis. The CA further improved when fewer classes were used. The highest binary classification accuracy, 94%, was obtained in low-grade glioma (grade II) versus control.CONCLUSIONSThe authors’ results show that surgical smoke from various brain tumors has distinct DMS profiles and the DMS analyzer connected to a special sampling system can differentiate between tumorous and nontumorous tissue and also between different tumor types ex vivo.
