Published: June 2019

Introduction and objectives: Opioid use disorder has become increasingly prevalent in recent years. Previous studies have shown that patients with opioid use disorder undergoing orthopedic, elective abdominopelvic, and cardiac procedures have poorer postoperative outcomes. The aim of this study was to examine the effect of pre-existing opioid use disorder on postoperative outcomes including in-hospital mortality, hospital length of stay (LOS), hospital readmission, and postoperative complications in patients undergoing appendectomy or cholecystectomy.Methods: The authors used administrative data from the State Inpatient Databases of the Healthcare Cost and Utilization Project for the years 2007-2014 from California, Florida, Kentucky, Maryland, and New York. The authors compared unadjusted rates of in-hospital mortality, postoperative complications, LOS, and 30-day and 90-day readmission status. The authors calculated the adjusted odds ratio (OR) for their outcomes using logistic regression models.Results: In all, 488,981 appendectomy patients and 790,491 cholecystectomy patients aged ≥ 18 years were included in the analysis. Appendectomy (OR 2.26) but not cholecystectomy patients with opioid use disorder had statistically significant adjusted odds of in-hospital death. Patients with opioid use disorder (overall reported, and by each procedure separately) had higher adjusted odds of postoperative complication (OR 1.46), 30-day readmission (OR 1.80), 90-day readmission (OR 1.98), and longer LOS (OR 1.37).Conclusions: The authors found higher unadjusted rates and adjusted ORs of in-patient mortality, hospital readmission, and postoperative complications in patients with opioid use disorder undergoing common abdominal surgeries. The authors’ study shows that opioid use disorder is a risk factor for poorer postoperative outcomes in this surgical patient population.

Published: June 2019

Introduction

Accumulating evidence has revealed the critical roles of long noncoding RNAs (lncRNAs) in various cancers. LncRNA SNHG20 has been shown to be a cancer-associated lncRNA in several cancers with diverse mechanisms. However, the clinical references, biological roles, and mechanisms of action of SNHG20 in prostate cancer (PCa) are still unclear.

Material and methods

The expression of SNHG20 in PCa tissues and cell lines was detected by RT-qPCR. The correlations between SNHG20 expression and clinicopathological features were analyzed by 2 test. The roles of SNHG20 in PCa cell proliferation and migration were detected by CCK-8, EdU incorporation, and transwell assays. The regulatory mechanisms of SNHG20 on DDX17 were detected by dual luciferase reporter assay, RT-qPCR, and western blot.

Results

SNHG20 is highly expressed in PCa tissues and cell lines. High expression of SNHG20 is positively correlated with high Gleason score and advanced tumor stage. Functional experiments revealed that overexpression of SNHG20 promotes PCa cell proliferation and migration. SNHG20 knockdown represses PCa cell proliferation and migration. Mechanistically, SNHG20 was verified to act as a competing endogenous RNA (ceRNA) to upregulate DDX17. DDX17 is also highly expressed and has oncogenic roles in PCa. Furthermore, the expression of DDX17 is significantly positively correlated with that of SNHG20 in PCa tissues. Depletion of DDX17 reverses the oncogenic roles of SNHG20 in PCa.

Conclusions

These data showed that SNHG20 promotes PCa cell proliferation and migration via acting as a ceRNA to upregulate DDX17. This study also suggested that SNHG20 may be a potential novel therapeutic target for PCa.
Nasal bone to nasal tip length ratio for describing nasal bone hypoplasia and predicting trisomy 21
Authors: Ekmekci Emre , Demirel Emine , Kelekci Sefa
Published: June 2019

Introduction

Fetal nasal bone hypoplasia has been proven to be a strong marker for trisomy 21 during second trimester ultrasonography. Rather than evaluating the nasal bone hypoplasia according to the nomograms, it may be possible to evaluate it with a more practical and specific method.

Material and methods

Retrospectively collected data were provided from the saved and stored patient data between 2012 and 2017. Nasal bone length and nasal tip length were measured and the ratio was calculated. The ratio ≤ 1/3 was defined as the threshold ratio for the definition of the marker. Nasal bone nasal tip length (NB/NL) ratio values were compared among groups with trisomy 21 and euploid fetuses.

Results

A total of 59 fetuses had trisomy 21 and 2304 euploid fetuses were included in the study. The ratio of nasal bone to nasal tip length was 1/3 and below in 21/59 (35.5%) of fetuses with trisomy 21 whereas this ratio was 31/2304 (1.3%) in euploid fetuses. The difference was statistically significant (p < 0.001). Sensitivity, specificity, positive likelihood ratio and negative likelihood ratio of nasal bone/nasal tip ratio ≤ 1/3 were 35.5%, 98.6%, 26.4 and 0.6 for Down syndrome, respectively.

Conclusions

This study suggested that the nasal bone to nasal tip length ratio may be a new promising and practical sonographic marker in the second trimester genetic sonography. Although its sensitivity is not high, it seems to be more practical and specific than the evaluation of fetal nasal bone length.

Published: June 2019

Introduction

The aim of the current study was to evaluate the association of spironolactone and arterial stiffness and composite cardiovascular disease (CVD, including coronary heart disease, congestive heart failure and ischemic stroke) in hypertensive patients.

Material and methods

Baseline data were collected and arterial stiffness was presented by carotid-femoral pulse wave velocity (cf-PWV) using applanation tonometry. Serum levels of fasting plasma glucose, total cholesterol, C-reactive protein and creatinine were measured using an automatic biochemistry analyzer. Plasma aldosterone concentration and plasma renin activity were determined by radioimmunoassay. The associations of spironolactone and arterial stiffness and composite CVD were evaluated.

Results

Compared to patients without spironolactone (n = 274), those with spironolactone (n = 170) were older and more likely to have diabetes and chronic heart failure. No differences in antihypertensive medications used were observed except for spironolactone. Mean number of antihypertensive medications used was significantly higher in the spironolactone group (2.6 ±0.8 vs. 2.2 ±0.6). Compared to patients without spironolactone, those with spironolactone had significantly lower cf-PWV (9.4 ±1.8 vs. 10.1 ±2.2 m/s). After adjustment for covariates, spironolactone was still associated with 10% lower risk of arterial stiffness, with a 95% confidence interval (CI) of 0.85–0.97. In patients without arterial stiffness, after adjustment for covariates, no significant association of spironolactone and composite CVD was observed. However, in patients with increased arterial stiffness, after adjustment for covariates, spironolactone was still independently associated with 11% lower risk of composite CVD (95% CI: 0.83–0.97).

Conclusions

Spironolactone treatment is independently associated with lower cf-PWV and lower prevalence of composite CVD in patients with increased arterial stiffness.
The Politics of Crackdowns on Africa's Informal Vendors
Authors: Resnick Danielle
Published: June 2019

Crackdowns on informal vendors are a common form of violence against the poor in many cities in developing countries. This article uses a media events database to examine crackdowns of informal vendors in Accra, Dakar, and Lusaka from 2000 to 2016. During this period, Accra demonstrated
consistently high levels of violence towards vendors, while violence increased in Dakar and decreased in Lusaka. The article argues that these trends are driven by differences in political decentralization for municipal authorities, variations in their administrative mandates over vending,
and the degree of influence vendors hold as an electoral constituency. Through a structured comparison of the governance of informal vendors across multiple cities, the article demonstrates how state violence manifests through everyday battles over access to public space.

Abstract. Pollen-induced allergies are among the most prevalent non-contagious
diseases, with about a quarter of the European population being sensitive to various
atmospheric bioaerosols. In most European countries, pollen information is
based on a weekly-cycle Hirst-type pollen trap method. This method is
labour-intensive and requires narrow specialized abilities and substantial
time, so that the pollen data are always delayed and subject to sampling- and
counting-related uncertainties. Emerging new approaches to automatic pollen
monitoring can, in principle, allow for real-time availability of the data
with no human involvement. The goal of the current paper is to evaluate the capabilities of the new
Plair Rapid-E pollen monitor and to construct a first-level pollen
recognition algorithm. The evaluation was performed for three devices
located in Lithuania, Serbia and Switzerland, with independent calibration
data and classification algorithms. The Rapid-E output data include
multi-angle scattering images and the fluorescence spectra recorded at
several times for each particle reaching the device. Both modalities of the
Rapid-E output were treated with artificial neural networks (ANNs) and the
results were combined to obtain the pollen type. For the first
classification experiment, the monitor was challenged with a large variety
of pollen types and the quality of many-to-many classification was
evaluated. It was shown that in this case, both scattering- and
fluorescence-based recognition algorithms fall short of acceptable quality.
The combinations of these algorithms performed better, exceeding 80 %
accuracy for 5 out of 11 species. Fluorescence spectra showed similarities
among different species, ending up with three well-resolved groups: (Alnus,
Corylus, Betula and Quercus), (Salix and Populus) and (Festuca, Artemisia and Juniperus). Within these groups, pollen is practically
indistinguishable for the first-level recognition procedure. Construction
of multistep algorithms with sequential discrimination of pollen inside
each group seems to be one of the possible ways forward. In order to connect
the classification experiment to existing technology, a short comparison
with the Hirst measurements is presented and the issue of false positive
pollen detections by Rapid-E is discussed.

Abstract. Losses of gas-phase compounds or delays on their transfer through tubing are
important for atmospheric measurements and also provide a method to
characterize and quantify gas–surface interactions. Here we expand recent
results by comparing different types of Teflon and other polymer tubing, as
well as glass, uncoated and coated stainless steel and aluminum, and other
tubing materials by measuring the response to step increases and decreases
in organic compound concentrations. All polymeric tubings showed absorptive
partitioning behavior with no dependence on humidity or concentration, with
PFA Teflon tubing performing best in our tests. Glass and uncoated and
coated metal tubing showed very different phenomenology due to adsorptive
partitioning to a finite number of surface sites. Strong dependencies on
compound concentration, mixture composition, functional groups, humidity,
and memory effects were observed for glass and uncoated and coated metals,
which (except for Silonite-coated stainless steel) also always caused longer
delays than Teflon for the compounds and concentrations tested. Delays for
glass and uncoated and coated metal tubing were exacerbated at low relative
humidity but reduced for RH >20 %. We find that conductive PFA
and Silonite tubing perform best among the materials tested for gas-plus-particle sampling lines, combining reduced gas-phase delays with good
particle transmission.
Quantitative stratigraphic analysis in a source-to-sink numerical framework
Authors: Ding Xuesong , Salles Tristan , Flament Nicolas , Rey Patrice
Published: June 2019

Abstract. The sedimentary architecture at continental margins reflects the interplay between the rate of change of accommodation creation (δA) and the rate of change of sediment supply (δS). Stratigraphic interpretation increasingly focuses on understanding the link between deposition patterns and changes in δA∕δS, with an attempt to reconstruct the contributing factors. Here, we use the landscape modelling code pyBadlands to (1) investigate the development of stratigraphic sequences in a source-to-sink context; (2) assess the respective performance of two well-established stratigraphic interpretation techniques: the trajectory analysis method and the accommodation succession method; and (3) propose quantitative stratigraphic interpretations based on those two techniques. In contrast to most stratigraphic forward models (SFMs), pyBadlands provides self-consistent sediment supply to basin margins as it simulates erosion, sediment transport and deposition in a source-to-sink context. We present a generic case of landscape evolution that takes into account periodic sea level variations and passive margin thermal subsidence over 30 million years, under uniform rainfall. A set of post-processing tools are provided to analyse the predicted stratigraphic architecture. We first reconstruct the temporal evolution of the depositional cycles and identify key stratigraphic surfaces based on observations of stratal geometries and facies relationships, which we use for comparison to stratigraphic interpretations. We then apply both the trajectory analysis and the accommodation succession methods to manually map key stratigraphic surfaces and define sequence units on the final model output. Finally, we calculate shoreline and shelf-edge trajectories, the temporal evolution of changes in relative sea level (proxy for δA) and sedimentation rate (proxy for δS) at the shoreline, and automatically produce stratigraphic interpretations. Our results suggest that the analysis of the presented model is more robust with the accommodation succession method than with the trajectory analysis method. Stratigraphic analysis based on manually extracted shoreline and shelf-edge trajectory requires calibrations of time-dependent processes such as thermal subsidence or additional constraints from stratal terminations to obtain reliable interpretations. The 3-D stratigraphic analysis of the presented model reveals small lateral variations of sequence formations. Our work provides an efficient and flexible quantitative sequence stratigraphic framework to evaluate the main drivers (climate, sea level and tectonics) controlling sedimentary architectures and investigate their respective roles in sedimentary basin development.
Analysis of the effects of biases in ensemble streamflow prediction (ESP) forecasts on electricity production in hydropower reservoir management
Authors: Arsenault Richard , Côté Pascal
Published: June 2019

Abstract. This paper presents an analysis of the effects of biased
extended streamflow prediction (ESP) forecasts on three deterministic
optimization techniques implemented in a simulated operational context with
a rolling horizon test bed for managing a cascade of hydroelectric reservoirs
and generating stations in Québec, Canada. The observed weather data were
fed to the hydrological model, and the synthetic streamflow subsequently generated
was considered to be a proxy for the observed inflow. A traditional,
climatology-based ESP forecast approach was used to generate ensemble
streamflow scenarios, which were used by three reservoir management
optimization approaches. Both positive and negative biases were then forced
into the ensembles by multiplying the streamflow values by constant factors.
The optimization method's response to those biases was measured through the
evaluation of the average annual energy generation in a forward-rolling
simulation test bed in which the entire system is precisely and accurately
modelled. The ensemble climate data forecasts, the hydrological modelling and
ESP forecast generation, optimization model, and decision-making process are
all integrated, as is the simulation model that updates reservoir levels and
computes generation at each time step. The study focussed on one hydropower
system both with and without minimum baseload constraints. This study finds
that the tested deterministic optimization algorithms lack the capacity to
compensate for uncertainty in future inflows and therefore place the
reservoir levels at greater risk to maximize short-term profit. It is shown
that for this particular system, an increase in ESP forecast inflows of
approximately 5 % allows managing the reservoirs at optimal levels and
producing the most energy on average, effectively negating the deterministic
model's tendency to underestimate the risk of spilling. Finally, it is shown
that implementing minimum load constraints serves as a de facto control on
deterministic bias by forcing the system to draw more water from the
reservoirs than what the models consider to be optimal trajectories.
Sediment budget analysis of the Guayas River using a process-based model

Published: June 2019

Abstract. The equatorial Daule and Babahoyo rivers meet and combine into the tidal Guayas River, which flows into the largest estuary on the Pacific coast of South America. The city of Guayaquil, located along the Guayas, is the main port of Ecuador but, at the same time, the planet's fourth most vulnerable city to future flooding due to climate change. Sedimentation, which has increased in recent years, is seen as one of the factors contributing to the risk of flooding. The cause of this sedimentation is the subject of the current research. We used the process-based Delft3D FM model to assess the dominant processes in the river and the effects that past interventions along the river and its estuary have had on the overall sediment budget. Additionally, a simulation including sea level rise was used in order to understand the possible future impact of climate change on the sediment budget. Results indicate an increase in tidal asymmetry due to land reclamation and a decrease in episodic flushing by river floods due to upstream dam construction. These processes have induced an increased import of marine sediment potentially responsible for the observed sedimentation. This is in contrast with the local perception of the problem, which ascribes sedimentation to deforestation in the upper catchment. Only the deposition of silt and clay in connected stagnant water bodies could perhaps be ascribed to upstream deforestation.
Large eddy simulation modeling of tsunami-like solitary wave processes over fringing reefs

Published: June 2019

Abstract. Many low-lying tropical and subtropical reef-fringed coasts are vulnerable
to inundation during tsunami events. Hence accurate prediction of tsunami
wave transformation and run-up over such reefs is a primary concern in the
coastal management of hazard mitigation. To overcome the deficiencies of
using depth-integrated models in modeling tsunami-like solitary waves
interacting with fringing reefs, a three-dimensional (3-D) numerical wave
tank based on the computational fluid dynamics (CFD) tool
OpenFOAM® is developed in this study. The Navier–Stokes
equations for two-phase incompressible flow are solved, using the large eddy simulation (LES) method for turbulence closure and the volume-of-fluid (VOF)
method for tracking the free surface. The adopted model is firstly validated
by two existing laboratory experiments with various wave conditions and reef
configurations. The model is then applied to examine the impacts of varying
reef morphologies (fore-reef slope, back-reef slope, lagoon width,
reef-crest width) on the solitary wave run-up. The current and vortex
evolutions associated with the breaking solitary wave around both the reef
crest and the lagoon are also addressed via the numerical simulations.
Apparent discrepancy of Tibetan ice core δ18O records may be attributed to misinterpretation of chronology

Published: June 2019

Abstract. Ice cores from the Tibetan Plateau (TP) are widely used for
reconstructing past climatic and environmental conditions that extend beyond
the instrumental period. However, challenges in dating and interpreting ice
core records often lead to inconsistent results. The Guliya ice core drilled from the northwestern TP suggested a cooling trend during the mid-Holocene based on its decreasing δ18O values, which is not observed in other Tibetan ice cores. Here we present a new high-resolution δ18O record of the Chongce ice cores drilled to bedrock ∼30 km away from the Guliya ice cap. Our record shows a warming trend during
the mid-Holocene. Based on our results as well as previously published ice
core data, we suggest that the apparent discrepancy between the Holocene
δ18O records of the Guliya and the Chongce ice cores may be
attributed to a possible misinterpretation of the Guliya ice core
chronology.

The objective of this study is to investigate the effectiveness of a counseling program in modifying the negativebehavior of male students aged 11-15 years. The researcher used the semi-empirical approach with twomeasurements, pre and posttest measurements. A purposive sample of 52 students was selected and divided into twogroups, experimental and control groups. Each group comprised a number of 26 male students respectively. Theresearcher developed the behavioral modification and counseling program questionnaire.The study showed that there were statistically significant differences in reducing the level of negative behavior in theexperimental group attributed to the counseling program. The experimental group mean reached a score of 87.08 andthe control group’s mean was 227. The results also indicated that the experimental group has a statisticallysignificant difference for the minimum permissible level of negative behavior (110), where the mean for negativebehavior reached 87.08, a decrease of 22.92. The effect of the independent factor on the dependent factor wassignificant, given that the d-value was 2.07, which is greater than the value 0.8. The study recommended for thegroup counseling program to be employed and circulated due to its positive results in modifying behavior.
Treatment of Incarcerated Impaction of Acetabular Fractures With Concomitant Osteochondral Femoral Head Fractures by the Use of a Posterior Wall Osteotomy and Surgical Hip Dislocation: A Novel Technique
Authors: Papachristos Ioannis V. , Johnson Joey P. , Giannoudis Peter V.
Published: June 2019

Acetabular articular impaction may well accompany acetabular fractures. Anatomic restoration of acetabular congruence is imperative to achieve longevity of the hip joint. Combination of incarcerated acetabular impaction with osteochondral femoral fracture is a true challenge for the pelvic surgeon to address. We describe a technique to treat a posterior column acetabular fracture in association with incarcerated articular impaction and concomitant osteochondral femoral fracture. Posterior wall osteotomy combined with surgical hip dislocation facilitates the restoration of femoral head anatomy and acetabular surface integrity. This technique should be considered when dealing with this difficult scenario.
Syntactic Constructions Featuring Multifunctional Sentence Components in the Language of Modern Business Media
Authors: Malyuga Elena , Poliakova Nataliia , Tomalin Barry
Published: June 2019

The paper summarises research findings concerned with the study of functional and cognitive properties of multifunctional sentence components used in the framework of business communication, as well as their actualisation in the context of the speaker’s linguistic identity. While such components appear understudied, they largely shape the linguacultural profile of a given language. Therefore, a study promoting accurate perception of their properties may lay the ground for a better and more productive intercultural business interaction. The study considers language units functioning at different levels in English, French and Russian to single out the types and functions of syntactic relationships registered in these languages, as well as the means of their expression. The study shows that as far as syntactic constructions featuring multifunctional coordinating components are concerned, their specifics is manifested not only in the set of coordinating means, but also in the peculiarities of their functioning.

Published: June 2019

This study aimed to analyze the Brazilian competitiveness in the world market of the main non-timber forest products (NTFPs) exported by Brazil during the subperiods from 2006 to 2010, and from 2011 to 2016. The products were selected based on their relevance in the Brazilian NTFP export. In order to analyze competitiveness, we used the competitiveness matrix, which is given by the performance point of view. In the construction of this matrix, the vertical axis was represented by the Revealed Symmetric Comparative Advantage index while the horizontal axis was represented by the growth rate. The results showed that natural rubber was in the “missed opportunities” quadrant in the first period and in the “retreat” quadrant in the second period analyzed. On the other hand, honey, mate and cashew nut were positioned in the “optimum” sector in both periods, although cashew nut had showed a decrease both in the world growth rate and in the RSCA in the second period studied. In the final analysis, we concluded that Brazil is competitive in exports of honey and mate, it has been losing competitiveness in exports of cashew nuts, and is in decline as regards natural rubber exports.

Published: June 2019

The objective of this research was to do the physical characterization of cotton species (Gossypium spp.) based on the attributes of the seed. The experiment was performed at the Forage Biochemistry Laboratory of the Valle of Mexico Experiment Station, using seed of four cotton species (G. hirsutum, G. aridum, G. lobatum and G. shwendimanii). This research was carried out in two phases: in the first one, the weight of 1000 seeds and the hectolitre weight were determined. In the second one, seed dimensions were obtained by digital images and analysis process. The four cotton species were tested under a completely random experimental design. The data analysis was made by the variance analysis method, Tukey multiple comparison tests of means, principal components and cluster analysis. The results showed significant differences (0.01%) in all the physical characters of the seeds. Based on the grouping analyzes, three groups with contrasting characteristics among the cotton species were identified, being G. hirsutum, the species that presented the highest value in the vector magnitude of the physical characters of the cottonseed. The area, width and weight of 1000 seeds were the main variables that explained 98.6% of the variability existing in the characteristics of the seed, so these physical attributes play an important role in the characterization of the Gossypium native species of Mexico.

Partiendo del caso de Yucatán, provincia y capitanía general de la Nueva España y luego uno de los estados federados de la Primera República federal del México independiente, se estudian las siguientes instituciones: los cabildos tradicionales, la Diputación provincial en sus dos períodos de vigencia de 1813–1814 y a partir de 1820, las juntas generales de los años 1821–1823, el primer Congreso constituyente de Yucatán y los congresos regionales hasta 1829. Al analizar representaciones simbólicas y prácticas comunicativas como las ceremonias de instalación, las puestas en escena en la esfera pública y las prácticas cotidianas de la publicidad institucional, se llega a la conclusión de que, pese a algunas continuidades simbólicas con el viejo orden,  se establecieron paulatinamente prácticas institucionales muy distintas a las vigentes durante el Antiguo Régimen.
Construcción de una identidad regional a través de la cultura impresa (Michoacán, 1824-1851)
Authors: Sosa Alanís Tamara
Published: June 2019

El aspecto identitario como eje en la construcción del Estado mexicano se ha dejado de lado, a pesar de que a través de él podríamos resolver cuestionamientos tan profundos como qué somos. De ahí que el estudio de la conformación de la identidad de un estado y un obispado como Michoacán sea una oportunidad de acceder al pensamiento de esos nuevos ciudadanos.Para observar esa construcción identitaria, la cultura impresa es una herramienta que nos permite acceder a las reflexiones del habitante michoacano, al proceso de apropiación de su espacio y a la visualización de un territorio que contribuyó a construir una memoria colectiva anclada en las redes de sociabilidad y en las instituciones.
Geobotanical distinction using the floristic method: example of the Polish Pomerania
Authors: Zając Maria , Zając Adam , Łysko Andrzej , Popiela Agnieszka
Published: June 2019

In the geobotanical division of Poland, Pomerania was treated as a separate subdivision, divided into “coastal plains” and the “Pomeranian uplands” or, in the newest regionalization, the “Pomeranian division”. The goal of this paper is to determine how well the distinctiveness of Pomerania is floristically justified. A total of 1,467 native species occur within the area of Pomerania, representing 57.5% of the native flora of Poland. Fifty-seven species distinguishing Pomerania were selected and their phytogeographic features were discussed and compared to the Polish vascular flora. The distribution of 32 species (56.1%) is characterized as (sub)Atlantic/oceanic. Of the taxa that characterize Pomerania, 47.45% represent the northern element of the Polish flora and 7.01% the western element; species of the eastern element do not exist in Pomerania. The maximum entropy (MaxEnt) method was used for collective distribution analysis of the 57 selected taxa. The analyzes were performed using 41 environmental variables. All the species analyzed are strictly linked to the western and the North Atlantic part of Europe. Statistical evaluation of the MaxEnt model yielded an AUC value of 0.75 for both training and test. The most important environmental variables are minimum high (min_h), temperature annual range (bio07), and mean temperature of driest quarter (bio09). The results of the MaxEnt analysis allowed us also to verify the boundaries of the region and suggest new criteria for them. The southern limit of Pomerania should run along the northern boundary of the terminal moraine belt. Also, the area east of the Vistula does not contain abundant representatives of the flora characteristic for Pomerania. The results of the present study may be used for a broader discussion on the revision of the geobotanical division of Poland, at least in its northern part.

Authors: Plewa Anna , Köhler Piotr
Published: June 2019

The Herbarium of the Jagiellonian University in Kraków, Poland (KRA) has extensive collections. The Pinaceae family in KRA embraces 1,057 herbarium sheets and contains representatives of eight out of 11 genera usually distinguished in the family. The collection of the family in KRA contains ca. 54–61% of the 220–250 species occurring in the world. The most numerous species (116 sheets) is Pinus sylvestris. There is one isoneotypus of Larix decidua Mill var. carpatica Domin (KRA 224704) and one syntypus of Tsuga caroliniana Engelm. (KRA 224989) in the collection. There are 706 sheets from Europe, 504 of them come from areas covered by the contemporary borders of Poland, 206 from North America, 98 from Asia, two from Africa, and one from Australia. The herbal material of the family deposited in KRA was collected in the past 200 years. The oldest specimen was collected in 1821. There are 65 sheets which date from the nineteenth century, 56 from the years 1900 to 1918, 173 from 1919 to 1939, 532 from 1944 to 2000, and 139 sheets from the twenty-first century. The most interesting collections include: the exsiccata from the nineteenth century, sheets from China (1925–1926), sheets collected by various Russian expeditions to Siberia, the collection of Professors Jan Kornaś and Anna Medwecka-Kornaś from North America, and collections documenting the scientific activity of the “Kraków geobotanical school” in the twentieth century.

Published: June 2019

Objective: The aim of this study was to compare early outcomes of monopolar (MP) and bipolar (BP) radiofrequency
(RF) treatment of inferior turbinate hypertrophy from the perspective of both the patient and the surgeon.
Study design: Prospective, randomized, single-blind study.
Materials and Methods: Seventy-one patients with inferior turbinate hypertrophy resistant to medical treatment.
BP RF was used in 36 patients and MP RF in 35 patients, respectively. Patients received no other treatment during a
6-month follow-up. They were evaluated for symptoms such as nasal obstruction severity, nasal obstruction frequency,
postnasal drip, nasal crusting, hyposmia, patient satisfaction, and preoperative pain with the use of a visual analogue
scale (VAS) before surgery and then 1 and 7 days as well as 1, 3, and 6 months after surgery.
Results: No significant difference was observed regarding symptoms of patients after BP and MP inferior turbinate
RF surgery in a long-term follow-up. Patients treated with MP RF showed early symptom improvement on days 1 and
7 days after surgery compared to the BP group. Procedure duration of MP RF was longer than that of BP RF. Pain during
surgery was reported more frequently in the BP group.
Conclusion: MP and BP RF treatment showed no difference in long-term efficacy. However, MP RF therapy was associated
with early symptom improvement and less pain reported by patients in comparison to the BP RF group.

Background
Reoperations in colorectal surgery are usually a consequence of major surgical complications. Recently, the rate of reoperation has been proposed as a marker of surgical performance. Yet, the incidence of re-intervention varies significantly in literature, ranging from 5,2 % to 13 %. Therefore, in this study, we investigated 30-day reoperation rates and made an attempt to identify risk factors of re-intervention following colorectal resection at our institution.

Methods
This is a retrospective study of patients who had undergone colorectal resection at a single institution from 2013 to 2017. Univariate and multivariate analysis of predicting factors were performed.

Results
Out of 464 patients included 51 required reoperations (11%). The most common causes of reoperations were anastomotic leakage, postoperative bleeding, and wound dehiscence. In univariate analysis the age of the patient and location of the tumor were related to an increased rate of reoperation. In multivariate analysis patients older than 75 (OR = 2.1; 95%CI = 1.1-3.9) and tumors sited in the rectum
(OR = 2.66; 95%CI = 1.4-5) were associated with an increased risk of re-intervention.
Patients who required postoperative re-intervention stayed in hospital longer (14 vs. 6 days, p <0.0001) and had higher mortality (9.8% vs. 1.2%, p=0.002).

Conclusions
Our study shows that reoperation rates that follow colorectal surgery are frequently undervalued. In our series, 11% of patients required an unplanned return to the operative room. The patient’s age and the rectal tumors were the two independent factors that affect the rate of reoperation.
Analysis of the “lone wolf” phenomenon in the context of the Leaderless Resistance Strategy
Authors: Doroszczyk Justyna
Published: June 2019

The article presents an analysis of the phenomenon of a terrorist – a lone wolf in the context of the leaderless resistance strategy. The aim of the article is to show that individual terrorism is a basic element of the leaderless resistance strategy. The research problem is the impact of the leaderless resistance strategy on the actions of individual terrorists who organize and carry out a terrorist attack without the support of a terrorist organization. According to the leaderless resistance strategy, an individual is sufficient to organize and implement a terrorist attack.
The Leaderless Resistance Strategy assumes maximum decentralization. The key is the existence of individuals who, sharing a particular worldview, are capable of independent organization and launching an attack. When attempting an attack, a lone wolf is appropriately motivated ideologically, but does not maintain contact with the hierarchy of the organization, and thus enhances the effect of intimidation of the society.
Individual terrorism, based on the leaderless resistance strategy, is becoming the most popular form of terrorism. An element of the Leaderless Resistance Strategy are operations carried out by lone wolves, small groups or cells regardless of the support of official organizational structures.
