Background and objectives

Poor identification of individuals with CKD is a major barrier to research and appropriate clinical management of the disease. We aimed to develop and validate a pragmatic electronic (e-) phenotype to identify patients likely to have CKD.

Design, setting, participants, & measurements

The e-phenotype was developed by an expert working group and implemented among adults receiving in- or outpatient care at five healthcare organizations. To determine urine albumin (UA) dipstick cutoffs for CKD to enable use in the e-phenotype when lacking urine albumin-to-creatinine ratio (UACR), we compared same day UACR and UA results at four sites. A sample of patients, spanning no CKD to ESKD, was randomly selected at four sites for validation via blinded chart review.

Results

The CKD e-phenotype was defined as most recent eGFR <60 ml/min per 1.73 m2 with at least one value <60 ml/min per 1.73 m2 >90 days prior and/or a UACR of ≥30 mg/g in the most recent test with at least one positive value >90 days prior. Dialysis and transplant were identified using diagnosis codes. In absence of UACR, a sensitive CKD definition would consider negative UA results as normal to mildly increased (KDIGO A1), trace to 1+ as moderately increased (KDIGO A2), and ≥2+ as severely increased (KDIGO A3). Sensitivity, specificity, and diagnostic accuracy of the CKD e-phenotype were 99%, 99%, and 98%, respectively. For dialysis sensitivity was 94% and specificity was 89%. For transplant, sensitivity was 97% and specificity was 91%.

Conclusions

The CKD e-phenotype provides a pragmatic and accurate method for EHR-based identification of patients likely to have CKD.

Background: Sickle cell anemia is the most common genetic disease in sub-Saharan Africa. It is an inherited autosomal recessive disorder characterized by chronic hemolysis secondary to falciformation of red blood cells, also responsible of ischemia, bone infarction and accompanied by serious infections and organic lesions.Normal for weight at birth, Sickle cell anemia subjects have low pre puberty growth compared to normal children and also have compromised bone remodeling balance which results in decrease of bone mass and increase of bone fragility. Several studies have established that 37% to 50% of SCA patients were osteopenic or osteoporotic. This study aims to confirm the existence of bone remodeling disorders with osteoporotic translation and to compare the values found in Congolese sickle cell adults subjects to the general population.Methods: Spine and hip DXA were conducted on 270 SS homozygotes aged 18 to 50 years (121 men and 149 women) and 359 AA homozygotes as controls (138 men and 221 women), aged from 18 to 50 years old, who agreed to participate in the study, considered as a control group. AS heterozygotes were not included in the study.Results: AA subjects shows higher density (BMD) and Bone mineral content (BMC) values. Both SCA and AA controls showed the characteristic curve with peak bone mass at the fourth decade of life, followed by a decay with age. The difference in BMD and BMC with the control population ranged from 7.94% to 26.34% (average of 16.02%) which means -0.8 to -2.7 standard deviations, whereas, compared to the T -score in the Congolese population, was 11.6% to 22.15% less (average of -17.5%) equivalent of -0.9 to -2 standard deviations.The overall decrease in bone mass rate for -2.5 DS of the T-score was: -28.4% and 33.2% for -2 DS of T-score.Conclusion: SCA subjects shows high rate of osteopenia and osteoporosis and are more likely at risk for fractures.

Authors: WU Ling , ZHAO Weihua , ZHU Tong , LIU Haoxue
Published: August 2019

A real-vehicle experiment was carried out to study the effects of in-vehicle information on driver workload, during which data of the driver blink duration and frequency were collected to check for discrepancies among drivers with and without vehicle navigation usage. In the meanwhile, the blink characteristics of drivers with vehicle navigation device mounted at three different positions were explored through image prompt or image & sound multi-channel simultaneous prompt. Experimental results showed that when the data of blink with a duration of 0-200ms was distributed at a 10ms interval, the driver blink count distribution curve shows obvious bimodal characteristics. The peak of blink with 50-60ms duration was lower than that with 10-20ms duration when vehicle navigation was not used, and higher when vehicle navigation was used. The difference between medium and long blinks was not significant when the navigation device was mounted at different positions, yet the short blinks showed a significant difference. The peaks of blink count without voice navigation were all greater than those with voice navigation. In particular, without voice navigation, the short blinks increased obviously, and the medium blinks increased relatively, but the long blinks remained almost unchanged. The above results indicate that the driver workload was greater when using vehicle navigation. When the navigation device is installed in position B, the driver workload reaches the minimum. Using voice navigation could reduce driver workload.

Authors: Wardhani Jihan Kusuma
Published: August 2019

Dramaturgi Ludruk Karya Budaya Mojokerto-Jawa Timur pada Lakon Sarip Tambak Oso, adalah pengkajian teater rakyat yang orisinal oleh penulis. Ini merupakan penelitian yang menggunakan pendekatan kualitatif untuk mengetahui LKBM secara lebih mendalam melalui keilmuan dramaturgi. Kelompok ini telah bertahan lama, yaitu sekitar 48 tahun. Cerita STO telah hidup lebih lama dari pada kelompok LKBM. Ludruk telah menjadi hiburan khas Jawa Timur, dan cerita STO adalah salah satu legenda yang terus hidup di masyarakat Jawa Timur, khususnya Sidoarjo. Cerita STO sangat dekat dengan masyarakat dan konflik dalam lakon merupakan hal yang sering terjadi di masyarakat sehingga cerita ini mengingatkan betapa pentingnya komunikasi yang baik antara pemerintah dan masyarakat. Kebaruan penelitian ini adalah sampai saat ini belum ada yang melakukan penelitian secara kajian dramaturgi terhadap LKBM khususnya pada lakon STO. Lakon yang menceritakan tentang perjuangan hak seorang manusia yang bernama Sarip yang tidak mau membayar pajak karena kemiskinannya. Hal itu menimbulkan perlawanan terhadap pemerintahan Belanda dan antek-anteknya, hingga akhirnya kelemahan Sarip dicari agar dapat membunuhnya yaitu dengan membungkam teriakan sang Ibu agar tidak bisa membangunkan Sarip dari kematiannya. Cerita ini dianggap nyata oleh sebagian masyarakat yang ada di Wilayah Jawa Timur, khususnya di daerah Sidoarjo tepatnya di wilayah Tambak Oso. Seiring perkembangannya cerita ini kemudian menjadi pembelajaran bagi masyarakat setempat untuk lebih bijak menyikapi segala keputusan yang telah ditentukan pemerintah. Baik itu antara pemerintah dan rakyat hendaknya sama-sama melakukan komunikasi yang tepat agar tercipta keharmonisan. Melihat banyaknya terjadi mis komunikasi antara pemerintah dan rakyat dalam mengambil kebijakan. Kajian dramaturgi LKBM pada lakon STO diharapkan mampu menjadi pembelajaran baik itu ludruk sebagai kelompok kesenian rakyat, maupun ceritanya yang bisa menjadi pengetahuan bagi masyarakat.
Repairing earth dam drainage systems
Authors: Krutov Denis A.
Published: August 2019

Introduction: when reconstructing or overhauling dams, great attention should be paid to drainage systems as the most critical components of the installations. The article describes the typical malfunctions of earth dam pipe drainages. The research considers geological and hydrogeological features that were not taken into account when developing projects.

Materials and methods: control and measuring instrumentation (piezometer network), full-scale experiments on disabling pipe drainage and mathematical modelling were used as the filtration regime research methods.

Results: analysis of the hydrogeological features of the base of the right-bank floodplain dam of the Nizhegorodskaya hydroelectric power plant and field filtration observations revealed a strong drainage effect of the base on the filtration flow at several areas of the dam body. At the other areas, a high groundwater level position at the dam downstream and its outlet into the pipe drainage at the downstream were recorded. Substantiated by filtration calculations, the proposed repair of the drainage system consisted in designing open drainage along the dam axis and backfilling the territory at the downstream by 2.0 m that excludes impoundment of the territory without the pipe drainage.

Conclusions: the following engineering solutions can be recommended for repairing earth dam drainage systems: construction of backfill drainage trenches in the dam downstream, new pipe drainage at higher elevations or an open drainage channel in solid reinforced concrete arranged along the axis of the dam. The proposed version of the pipe drainage repair provides for constructing an open drainage channel in solid reinforced concrete on a reverse filter with an arrangement of gravel-filled asbestos-cement pipes in the dam slopes and bottom. Such a design solution allows repairing the drainage system without dewatering and, if necessary, completely refusing the existing pipe drainage.

A polar decomposition for quantum channels (with applications to bounding error propagation in quantum circuits)
Authors: Carignan-Dugas Arnaud , Alexander Matthew , Emerson Joseph
Published: August 2019

Inevitably, assessing the overall performance of a quantum computer must rely on characterizing some of its elementary constituents and, from this information, formulate a broader statement concerning more complex constructions thereof. However, given the vastitude of possible quantum errors as well as their coherent nature, accurately inferring the quality of composite operations is generally difficult. To navigate through this jumble, we introduce a non-physical simplification of quantum maps that we refer to as the leading Kraus (LK) approximation. The uncluttered parameterization of LK approximated maps naturally suggests the introduction of a unitary-decoherent polar factorization for quantum channels in any dimension. We then leverage this structural dichotomy to bound the evolution -- as circuits grow in depth -- of two of the most experimentally relevant figures of merit, namely the average process fidelity and the unitarity. We demonstrate that the leeway in the behavior of the process fidelity is essentially taken into account by physical unitary operations.
An algorithm for estimating the vector fields` curl of the earth’s surface motion from geodetic data
Authors: Mazurov B.T.
Published: August 2019

According to the changes of geodetic elements (coordinates, heights, directions) after multiple measurements, it is possible to represent the field of geodetic points’ displacement vector. When studying the stress-strain state of the earth’s surface, the vectors obtained can be used not only to calculate the earth’s deformation tensor in the area under study, but also the differential characteristics of the vector field, called divergence and rotor (vortex, curl). The author proposes the way to determinethe rotor according to discrete geodesic observations of displacement vectors on the surface of the surveyed area. The most important continuation of this research work is the method of geodynamic systemsmathematical modeling for predictive purposes. In order to study the complex (nonlinear) geodynamic processes, an appropriate mathematical basis should be chosen. Here the attention is drawn to the attraction of the mathematical foundations of field theory. The variants of the curl definition are proposed – one of the vector fields’ differential characteristics. To assess the characteristics of vector fields when using multiple geodetic measurements, the finite element method can be used. The division of the surveyed area into triangles enables you to determine the characteristics of the deformation after calculating the elements of the strain tensor.
Biruni’s Method of Measuring the Earth
Authors: Maslikov S. Yu.
Published: August 2019

A thousand years ago, one of the greatest scholars of the medieval Islamic era Iranian scientist-encyclopedist Abu Rayhan al-Biruni measured the Earth globe. He described the measurement process in his several treatises. Many of the more recent comments say that he received a very precise result, unrivaled until the New Time. The author provides a detailed analysis of Biruni’s measurement method, as well as an assessment of possible errors accompanying those measurements. Step by step the measurement process is reinstated; binding is made to specific places of observation, technical parameters of the instruments used are discussed. A parallactic method and instrument for measuring elevations proposed by Biruni is considered, which could only be put into practice in the 20th century. As a result of the research it was shown that Biruni’s method is not as accurate as it was believed. In addition, it is difficult to compare the unit of the length measurement used at Biruni’s time with modern ones.
As revoluções passivas neoliberais no pós-URSS: semelhanças e singularidades entre o caos neoliberal russo e ucraniano da década de 1990
Authors: Costa Lima Felipe
Published: August 2019

As consequências catastróficas das revoluções passivas ocorridas na Federação Russa e na Ucrânia nos anos 1990 somente podem ser compreendidas a partir de dois acontecimentos indispensáveis: a desintegração da ex-URSS e a expansão do neoliberalismo nesses novos Estados formalmente independentes. Desse modo, o fim do bloco histórico soviético e a instauração do discurso hegemônico neoliberal nesses dois países possibilitaram mudanças drásticas em todos os contextos, como político, econômico e social. De uma maneira talvez paradoxal, embora o fim da URSS e a expansão neoliberal sejam dois fatores comuns em ambas revoluções, elas são também os dois fatores diferenciadores. Portanto, o objetivo central deste artigo será explicitar as semelhanças e as diferenças desses dois processos, os quais são profundamente tributários da herança socioeconômica e política do período soviético.
The contribution of the United Nations police to the protection of civilians in South Sudan
Authors: Silva Josias Marcos de Resende
Published: August 2019

O Sudão do Sul tornou-se um Estado independente em 2011, após uma longa guerra civil contra o Sudão. No mesmo ano, a Missão das Nações Unidas no Sudão do Sul (UNMISS) foi estabelecida para consolidar a paz, a segurança e o desenvolvimento. Em 2013, uma sangrenta guerra civil, que estourou e permanece até os dias atuais, mudou o país e a natureza da missão da Organização das Nações Unidas (ONU), a qual tornou-se mais robusta e passou a abrigar cerca de 200.000 pessoas em locais de proteção de civis (PoC sites). Neste violento e complexo cenário, a Polícia das Nações Unidas (UNPOL), que é um importante componente dentro da UNMISS, enfrenta um desafio substancial na proteção dos civis em todo o país. Desta forma, este artigo examina a performance da UNPOL como o mecanismo de imposição da lei dentro dos PoC sites e também como seu emprego tem contribuído para a proteção de civis no Sudão do Sul. Assim, após uma pesquisa bibliográfica, uma entrevista com um policial brasileiro veterano da UNPOL, e a análise da taxa de crimes dentro dos PoC sites, foi possível verificar que a UNPOL exerce um papel fundamental dentro da UNMISS, assegurando um ambiente seguro para os deslocados internos que se encontram sob a proteção direta da ONU.

The objective of this study was to measure temperature changes in the pulp chamber induced by polymerization of resin-based dental restoratives following a simulated procedure of direct pulp capping. Class I cavities with a microperforation at the pulp horn were prepared in extracted human molar teeth. The complete procedure of direct pulp capping and cavity restoration was performed with the root part of extracted teeth fixed in a water bath at 37 ?C. Mineral trioxide aggregate, bioactive dentin substitute or calcium-hydroxide paste were used as pulp capping materials. Cavities were restored with a light-cured or chemically-cured resin-modified glass ionomer, universal adhesive and a bulk-fill composite, cured with a high-intensity LED unit. Pulp capping materials caused a slight temperature decrease. Lower temperature increase was recorded during light-curing of the glass ionomer liner after direct capping with mineral trioxide aggregate and calcium-hydroxide than that recorded for the bioactive dentin substitute. Adhesive light-curing increased temperature in all groups with higher mean temperatures in groups with chemically-cured as compared to those for the light-cured glass ionomer liner. Direct pulp capping with mineral trioxide aggregate or calcium-hydroxide followed by the light-cured resin-modified glass ionomer liner and a bonded bulk-fill composite restoration induced temperature changes below the potentially adverse threshold of 42.5?C.

Published: August 2019

Objectives

To (1) introduce a novel machine learning method and (2) assess maxillary structure variation in unilateral canine impaction for advancing clinically viable information.

Materials and Methods

A machine learning algorithm utilizing Learning-based multi-source IntegratioN frameworK for Segmentation (LINKS) was used with cone-beam computed tomography (CBCT) images to quantify volumetric skeletal maxilla discrepancies of 30 study group (SG) patients with unilaterally impacted maxillary canines and 30 healthy control group (CG) subjects. Fully automatic segmentation was implemented for maxilla isolation, and maxillary volumetric and linear measurements were performed. Analysis of variance was used for statistical evaluation.

Results

Maxillary structure was successfully auto-segmented, with an average dice ratio of 0.80 for three-dimensional image segmentations and a minimal mean difference of two voxels on the midsagittal plane for digitized landmarks between the manually identified and the machine learning–based (LINKS) methods. No significant difference in bone volume was found between impaction ([2.37 ± 0.34] 104 mm3) and nonimpaction ([2.36 ± 0.35] 104 mm3) sides of SG. The SG maxillae had significantly smaller volumes, widths, heights, and depths (P < .05) than CG.

Conclusions

The data suggest that palatal expansion could be beneficial for those with unilateral canine impaction, as underdevelopment of the maxilla often accompanies that condition in the early teen years. Fast and efficient CBCT image segmentation will allow large clinical data sets to be analyzed effectively.

Published: August 2019

Este artigo objetiva, na busca por fontes bibliográficas e com base no paradigma indiciário, compreender as abordagens progressistas da sociedade sobre os problemas políticos e educacionais dos anos 1950 e 1960 no Brasil. Entre diferenças e divergências quanto à cultura popular, com sua heterogeneidade cultural, étnica, regional e sua escassa tradição de luta operária, havia pontos de aproximação: o Serviço de Extensão Cultural da Universidade do Recife, os Centros Populares de Cultura e os Centros Regionais de Pesquisa Educacional apostavam na educação para o fortalecimento da democracia e no desenvolvimento econômico e social, bem como buscavam propostas sob medida para o âmbito educacional. Assim, a pesquisa e o diálogo, com suas exigências e práticas, constituíram-se parte essencial da energia considerada subversiva. Os achados e as repercussões das pesquisas aumentaram os receios de militares e civis, pois as mudanças alteravam um suposto equilíbrio e um ajustamento dos indivíduos ao meio social, segundo os setores conservadores e dominantes do País.

Published: August 2019

Di era ini, kenakalan remaja sudah sangat sering terjadi. Kenakalan remaja adalah suatu perbuatan yang melanggar norma aturan dan tata hukum masyarakat yang di lakukan pada usia remaja atau transisi dari masa anak-anak ke dewasa. Perilaku yang menyimpang dari norma hukum pidana yang dilakukan oleh remaja merupakan problema yang sering terjadi pada remaja baik di lingkungan keluarga, sekolah, maupun masyarakat. Jika tidak ditangani dengan baik, kenakalan remaja dapat berubah menjadi perilaku criminal dan dapat membawa remaja tersebut ke dalam penjara. Bila ditelusuri secara mendalam perkembangan kejahatan remaja banyak di pengaruhi dari kehidupan keluarga dan masyarakat. Keluarga memiliki peranan penting dalam mencegah kenakalan remaja. Salah satu cara yang dapat dilakukan keluarga untuk mencegah kenakalan remaja adalah dengan menggunakan pola asuh yang tepat. Pola asuh yang digunakan oleh orang tua memberikan pengaruh pada perilaku anak. Menurut hasil assessment di LPKA Sukamiskin, Bandung, ditemukan keterkaitan atau pengaruh antara pola asuh orang tua terhadap kenakalan dan perilaku criminal yang dilakukan oleh remaja.  In this era, juvenile delinquency is very common. Juvenile delinquency is an act that violates the norms and rules of law of society that are done in adolescence or the transition from childhood to adulthood. Behavior that deviates from criminal law norms committed by adolescents is a problem that often occurs in adolescents both in the family, school, and society. If not handled properly, juvenile delinquency can turn into criminal behavior and can bring the teenager into prison. When traced in depth the development of juvenile crime is influenced by family life and society. Family has an important role in preventing juvenile delinquency. One way that families can do to prevent juvenile delinquency is to use proper parenting. Parenting is used by parents to influence children's behavior. According to the results of the assessment at Sukamiskin LPKA, Bandung, it was found that the relationship between parents' parenting and delinquency behavior was carried out by teenagers.

Authors: Ait Bahammou Youssef , Benamara Ahmed , Ammar Abdellah , Dakir Ibrahim
Published: August 2019

Resistivity Profiling and Very Low Frequency (VLF) electromagnetic methods were introduced to study fracture zones detection in Zaouia Jdida locality, within the Errachidia basin. The Horizontal Profiling was conducted in Wenner-α array, with AB = 300 m and profile lines oriented NW–SE and NE–SW. The resistivity measurements were taken using MAE advanced geophysics instruments. The VLF profiles were implanted with the length reaches 1000 m and profile lines oriented in NE–SW direction. The VLF measurements were collected using T-VLF iris instrument and the data filtering was done using KHFFILT software. Two filters, Karous-Hjelt and Fraser, were applied to the real component of the secondary electromagnetic field. The qualitative interpretation of resistivity results, showed the presence of subsurface targets; fracture zones were detected at 70m, 240m and 450m positions along the profile P1, at 180m, 340m and 450m positions from the profile P2. The semi-quantitative interpretation of VLF results revealed the presence of two principal fracture zones at L3 and L5 locations, oriented NW–SE, at a depth range of 30 m to 60 m. The VLF anomaly observed at L3 location is confirmed by the resistivity measurements from the profile P1 (at 70m station). The identified fractures represent the potential zones for groundwater supply and then will have an implication on storage and movement of groundwater in the prospect area.

Published: August 2019

Results from a detailed gravity survey realized along the planned highway tunnel in the karstic area of Slovak Karst in the eastern Slovakia are presented. Detailed gravity profiles crossed an area of rugged topography, therefore the terrain corrections played a crucial role in the gravity data processing. The airborne laser scanning technique (LiDAR) was used in order to compile a high-resolution digital terrain model (DTM) of the surrounding area and to calculate terrain corrections properly. The difference between the Bouguer anomalies calculated with an available nationwide DTM and those with new LiDAR-based model can be significant in some places as it is presented in the paper. A new method for Bouguer correction density analysis based on surface data is presented. Special underground gravity measurements in the existing nearby railway tunnel were also conducted in order to determine the mean density of the topographic rocks. The Bouguer anomalies were used to interpret lithological contacts and tectonic/karstic discontinuities.

Research methodology: The research method used in the paper was a query of Polish and foreign literature of housing policy models, goals and instruments in the theoretical part, in the practical part (main research) is the monograph analysis of Polish housing policy between 2002 and 2016 including: housing resource, housing supply and change of their structure in the examined timeline, availability of apartments, supply of mortgages and connections with the availability of apartments and macroeconomic situation measured by the yearly GDP per capita.

Results: Theoretical and practical solutions were made. Polish housing policy can be defined as a wide ranging selective model according to Ghekiere (2009) division, the empirical analysis of the adopted solutions risks – marginalization of social housing and substantial impact of the financial sector (banking and mortgages) on housing which may be negative in the case of an economic crisis.

Novelty: The value of this paper is a contribution to the debate on defining a theoretical model of housing policy and an explanation of the changes in housing in Poland from 2002–2016.
Long-Term Equity Performance in Poland – Searching for Answers with the Calendar-Time Portfolio Approach
Authors: Lizińska Joanna , Czapiewski Leszek
Published: August 2019

Research background: The study examines the performance of companies that are going public with equity issuance (IPO) in Poland.

Purpose: Some scholars argue that the buy-and-hold strategy that has been quite widely used suffers from cross correlation and the “bad model” problem. Hence, the calendar-time portfolio approach is used to extend the methodology.

Research Methodology: The empirical procedure is two-step. At the beginning, we calculate an average abnormal return for the portfolio of IPOs firms. The portfolio is rebalanced each month. Next, the risk-adjusted performance is measured by regressing returns on a multifactor time-series regression model. We employ the Fama-French (1993) three-factor model and CAPM for the robustness check.

Results: In a sample of IPOs listed on the Warsaw Stock Exchange, we find negative and highly significant abnormal returns. Alphas are statistically significant in all of the Fama-French regressions and in most of the cases for CAPM.

Novelty: This paper discusses the puzzle of the long-term equity performance of initial public offerings (IPOs) using the calendar-time portfolio approach. Our results point to the economic and statistical significance of long-term IPO underperformance.

The objective was to evaluate the accuracy of predicting 24-hour milk yield and composition from a single morning (AM) or evening (PM) milk weight and composition. A calibration dataset of 37,481 test-day records with both AM and PM yields and composition was used to generate the prediction equations; equations were validated using 4,644 test-day records. Prediction models were developed within stage of lactation and parity while accounting for the inter-milking time interval. The mean correlation between the predicted 24-hour yields and composition of milk, fat and protein and the respective actual values was 0.97 when based on just an AM milk yield and composition with a mean correlation of 0.95 when based on just a PM milk yield and composition. The regression of predicted 24-hour yield and composition on the respective actual values varied from 0.97 to 1.01 with the exception of 24-hour fat percentage predicted from a PM sample (1.06). A single AM sample is useful to predict 24-hour milk yield and composition when the milking interval is known.

Authors: Roushan Mohammad Reza Hasanjani , Ebrahimpour Soheil , Afshar Zeinab Mohseni , Babazadeh Arefeh
Published: August 2019

Introduction

Human brucellosis, the most prevalent zoonotic disease worldwide, is a systemic infection which can involve several organs. Among musculoskeletal complaints, spondylitis is the most frequent complication of brucellosis and primarily affects the lumbar and thoracic vertebrae. The involvement of the cervical spine is infrequent.

Case report

This case report concerns an unusual case of cervical spine spondylitis with an epidural abscess due to Brucella in a 43-year-old man. The diagnosis was based on the patient being domiciled in an endemic region, his symptoms and his occupation. Clinical outcomes improved following antimicrobial therapy of rifampin, doxycycline, and gentamycin, and were confirmed radiologically.

Conclusion

Early diagnosis and treatment are crucial for these patients. The timely commencement of medical treatment can help prevent surgery.

Introduction

The current lack of clear guidelines on how to manage cases of brain-dead pregnant patients makes this topic controversial and extremely difficult to deal with for both medical and ethical reasons. This report deals with such a situation.

Case presentation

A twenty-seven years old woman, thirteen weeks pregnant, with a ruptured brain aneurysm was admitted to an Intensive Care Unit. She presented with loss of all brain functions, but somatic support was sustained to enable the delivery of her baby.

Conclusion

The case report gives a detailed account of the management of the mother before the successful delivery of her baby. It indicates the need for ongoing contributions to the debate on this delicate subject area to establish guidelines on how to manage brain-dead pregnant patients.
Precision Medicine and its Role in the Treatment of Sepsis: A Personalised View
Authors: Lazăr Alexandra , Georgescu Anca Meda , Vitin Alexander , Azamfirei Leonard
Published: August 2019

In recent years, a new form of medicine has become increasingly significant, namely, personalised medicine (PM). PM is a form of care in which treatment is tailored for an individual patient.

PM is about using multiple data sets to create a digital human mapping. A person’s biological traits are determined by the interactions of hundreds of genes and gene networks, as well as external factors such as diet and exercise. Combining and then investigating these multiple databases with powerful statistical tools, allows a new understanding of how genetic intricacy drives health and disease and so leads to a closer personalised medical approach that targets each individual’s unique genetic make-up.

Sepsis is a systemic inflammatory response to infection, ranging from systemic inflammatory response syndrome (SIRS) to septic shock and multiple organ dysfunction syndromes (MODS). Sepsis is the most common cause of death in intensive care patients. Treatments in an ICU may need to be adapted to the continuous and rapid changes of the disease, making it challenging to identify a single target. PM is thus seen as the future of sepsis treatment in the ICU.

The fact that individual patients respond differently to treatment should be regarded as a starting point in the approach to providing treatment. The disease itself comes secondary to this concept.
Evaluating the Prevalence and Distribution of Unregistered Employment in Kosovo: Lessons from a 2017 Survey
Authors: Gashi Ardiana , Williams Colin C.
Published: August 2019

Despite the growing recognition that unregistered employment remains a common problem both in South-East Europe and well beyond, there has been little evidence available on its prevalence and distribution. This paper contributes to filling the gap, by utilising data from a 2017 large scale national representative survey of 8,533 households in Kosovo. This reveals that 34.6% of all employees are engaged in unregistered employment (i.e., they have no employment contract). A Probit regression analysis reveals significant associations between unregistered employment and individual, household, employer and job-related characteristics. Unregistered employment is significantly more prevalent among men, younger people, single, widowed or divorced, those with fewer years in education, living in rural areas and in larger households. It is also significantly more prevalent among those working in construction and services, part-time employees, with shorter employment durations, lower wages, and those in elementary occupations and craft and related trades. The wider theoretical and policy implications are then discussed.
Determinants of Current Account in Cases of Serbia and Romania: Time-Varying Parameters Approach
Authors: Bošnjak Mile
Published: August 2019

Following competing theories, the paper brings the determinants of the Serbian and Romanian current account dynamics with policy implications. The research sample consists of quarterly time series data over the period 2004q1–2017q2 and 2007q1-2017q4 for the cases of Serbian and the Romanian case, respectively. The estimates from the state space model with time-varying parameters (TVP) approach suggest that role of domestic demand is significant in both cases even though more prominent in case of Serbia. Marshall-Lerner conditions were fulfilled in case of Serbia while not in the Romanian case. The effects of money supply on the current account is found to be in line with the monetary approach in case of Romania while in the Serbian case the effect of an increase in the money supply is positive. Consequently, to resolve the issue of the current account deficit the research findings suggest the country-specific policy mix for each country.
The Principal Threats to the Standing Water Habitats in the Continental Biogeographical Region of Central Europe
Authors: Grzybowski Mirosław
Published: August 2019

This paper discusses threats of standing water habitats of high importance to the European Community in the Continental Biogeographical Region (CBR) of Europe, specifically in Poland, as a reference. The study covers five standing water habitats types distinguished in Natura 2000: 3110, 3130, 3140, 3150, 3160, occurring in 806 Special Areas of Conservation (SACs) in Poland. The most significant threats to standing water habitats in the Continental biogeographical region, result from human-induced changes in hydrological conditions that have modified whole natural systems. Based on multivariate analysis, we found that significant differences in the conservation status of the standing water habitats resulted from a variety of threats, pressures, and activities, among which the most significant are decreased and unstable water resources (3110, 3130, 3140, 3150, 3160), fishing and harvesting aquatic resources (3110, 3130, 3140, 3150, 3160), pollution from use of the catchment (3130, 3140, 3150), improper management and use of the agricultural catchment (3110, 3130, 3140, 3150, 3160) and forest catchment (3110, 3140, 3160), urbanisation, residential and commercial development (3150, 3140), transportation and service corridors (3140> 3160 > 3110, 3150), including parking areas (3140), changes in biocenotic evolution, succession, plant species composition (3110, 3130, 3140, 3150, 3160), succession of invasive species (3130), and more intense touristic exploration (3110, 3130, 3140, 3150, 3160). Only in the case of habitats 3110, 3130, 3140 changes in their conservation status have been associated with climate change.
