Authors: Pankov E. A. , Papayan K. A. , Kapustin S. I. , Savenkova N. D.
Published: April 2020

INTRODUCTION. The basis of hemolytic-uremic syndrome (HUS) is the pathology of hemostasis with the development of a condition that threatens the patient's life. Violations of the hemostatic system are probably largely due to a hereditary predisposition to thrombophilia.

THE AIM. To study the characteristics of allelic polymorphism of genes associated with hereditary thrombophilia in 15 children with hemolytic-uremic syndrome.

PATIENTS AND METHODS. A study was conducted of 15 children with HUS from the age of 1 to 4 years who were treated in the nephrology department of the clinic of St. Petersburg State Medical University. A typical HUS was diagnosed in 14 children. One child was diagnosed with atypical HUS confirmed by laboratory tests (increased levels of antibodies to protein H). At the Research Institute of Hematology and Transfusiology of the FMBA of Russia, PCR for all 15 patients and two parents analyzed the polymorphism of genes associated with thrombophilia.

RESULTS. In all examined children, polymorphism of genes associated with various links of hemostasis was found. Two patients showed a mutation in the factor V gene (FV Leiden). In 7 patients out of 15 subjects, the homozygous state of the plasminogen activator inhibitor (PAI-1 - 675 4G / 5G) was revealed.

CONCLUSION. The FV Leiden mutation, as the main reason for the resistance of activation of protein C (an inhibitor of the formation of thrombin), was found in two children, one with a typical HUS, and one with an atypical HUS. In 7 children out of 15 subjects, a homozygous state of plasminogen activator inhibitor (PAI-1 - 675 4G / 5G) was revealed, which may indicate insufficient fibrinolytic activity in these children, as an important factor contributing to the development of TMA.

Sidelobe Reduction in a Planar Array using Genetic Algorithm under Backlobe Reduction Condition
Authors: Manandhar Reena , Suksompong Prapun , Charoenlarpnopparut Chalie
Published: April 2020

The peak sidelobe level (PSL) minimizing amplitude weights for planar array, with 3D beamforming under the backlobe level reduction (BLL) condition is proposed. Binary genetic algorithm (BGA) is performed on the amplitude weights to achieve low PSL. BLL reduction condition for the inter-element distance between the antenna elements is applied to achieve reduced BLL. Earlier studies only focus on minimizing sidelobe level of planar array. BLL reduction condition has not yet been applied for planar array case. Hence a different way of achieving the amplitude weights to reduce PSL with 3D beamforming using BGA, under the BLL reduction condition is proposed in this paper. Obtained PSL and BLL for  planar array by applying optimized weights under BLL condition is -20.89 dB and -2.37 dB respectively. PSL is reduced by 8.84 dB compared to  uniform planar array. BLL is reduced by 2.37 dB compared to planar array discussed in existing research work.

Authors: Sumanonta Kotchapong , Suwanapingkarl Pasist , Liutanakul Pisit
Published: April 2020

This article presents a novel model for the equivalent circuit of a photovoltaic module. This circuit consists of the following important parameters: a single diode, series resistance (Rs) and parallel resistance (Rp) that can be directly adjusted according to ambient temperature and the irradiance. The single diode in the circuit is directly related to the ideality factor (m), which represents the relationship between the materials and significant structures of PV module such as mono crystalline, multi crystalline and thin film technology.
 Especially, the proposed model in this article is to present the simplified model that can calculate the results of I-V curves faster and more accurate than other methods of the previous models. This can show that the proposed models are more suitable for the practical application.
In addition, the results of the proposed model are validated by the datasheet, the practical data in the laboratory (indoor test) and the onsite data (outdoor test). This ensures that the less than 0.1% absolute errors of the model can be accepted.
Scalarized Q Multi-Objective Reinforcement Learning for Area Coverage Control and Light Control Implementation
Authors: Phuphanin Akkhachai , Usaha Wipawee
Published: April 2020

Coverage control is crucial for the deployment of wireless sensor networks (WSNs). However, most coverage control schemes are based on single objective optimization such as coverage area only, which do not consider other contradicting objectives such as energy consumption, the number of working nodes, wasteful overlapping areas. This paper proposes on a Multi-Objective Optimization (MOO) coverage control called Scalarized Q Multi-Objective Reinforcement Learning (SQMORL). The two objectives are to achieve the maximize area coverage and to minimize the overlapping area to reduce energy consumption. Performance evaluation is conducted for both simulation and multi-agent lighting control testbed experiments. Simulation results show that SQMORL can obtain more efficient area coverage with fewer working nodes than other existing schemes.  The hardware testbed results show that SQMORL algorithm can find the optimal policy with good accuracy from the repeated runs.

Published: April 2020

The reactive power is the background power without which the active power cannot be transmitted in the power systems. In the modern power system, the reactive power pricing is considered as essential in order to maintain the voltage in the transmission line. The modern power system is the grid that functions with smart innovative technological system that provides flexibility, efficiency and availability for the users. The smart grid uses the Internet of Things (IoT) technology to identify and provides the requirement of system reactive power for reactive power pricing. The IoT based wireless communication platform significantly reduces the latency and provides better accuracy. The system requirements for reactive power are optimally dispatched by the generator and other reactive power provider using optimization algorithm like Self Balanced Differential Evolution. Here the analytics and opportunities of smart grid for reactive power service are discussed using 62 bus Indian Utility System (IUS).

Partial methodology for assessing the level of methodological training of trainers during combat training of tank brigade during combat readiness
Authors: Kharabara Vоlodymyr , Repilo Iurii
Published: April 2020

The experience of using tank brigade and units in the of anti-terrorist operation (ATO) and the operation of the Joint Forces (OJF), which are the main strike force of the Land Forces, indicates that their successful combat performance depends to a large extent on their combat capability. The level of preparedness of the brigade has a direct impact on combat capability.During combat renewal, combat training activities are conducted during which the training facilities acquire certain capabilities to perform combat missions. Due to the limited time involved in conducting combat training, methodological training of trainers has a significant impact on their level of training. This requires the search and implementation of new approaches to the quality of combat training activities by leaders of training in the course of combat readiness, which requires the development of a scientific and methodological apparatus to assess their level of methodological training. The article proposes a partial methodology for assessing the level of methodological training of leaders of training during combat training in the course of combat readiness, as part of a comprehensive methodology for assessing the effectiveness of combat tank training in the course of combat capability, which allows to take into account the impact of training leaders on the quality of training. The use of the proposed method allows the training subjects to quantify the level of methodological training of the trainers and to identify problems in the organization of their classes. The above methodology uses indicators that characterize the level of knowledge and skills of the head teacher in the subject of study, their experience in their classes and the availability of training courses to improve pedagogical skills.

Published: April 2020

To explore the emerging concerns of COVID-19 related issues amongst health care workers, members of a range of healthcare organisations, governmental agencies, and the media, and online self-administered survey of healthcare workers was undertaken by the British Association of Physicians of Indian Origin in April 2020.
Results
The respondents were predominantly hospital doctors (67%), aged between 40-60 years (72%) and from Black, Asian, and Minority Ethnicity (BAME) backgrounds in the UK (86%). Thirty percent of respondents had one or more vulnerable comorbidities. Over 78% reported either lack of, or inappropriate Personal Protective Equipment (PPE) for their role and 68% of respondents felt that they were unable to comply with or that it was impractical to adhere to social distancing at work (including commuting). At the time of the survey, 18.5% of respondents reported having a confirmed or suspected diagnosis of COVID-19. In multivariate analysis, the BAME community emerged as an independent risk factor (OR 1.45) for COVID-19 when adjusted for confounding factors.
Conclusions
These results add to the emerging concerns expressed internationally on the observation that BAME ethnicity appears to have a higher risk of developing COVID-19. This is the first study that adjusted work-related factors (inability to maintain social distancing and inadequate PPE) and comorbidities. Our work supports the imperative for designing and conducting urgent larger studies to understand this risk and plan appropriate mitigation of the risks to health care workers
REVISION OF PV2 CRITERIA BASED PEDESTRIAN CROSSING WARRANTS
Authors: Jain Udit , Rastogi Rajat
Published: April 2020

Several guideline documents on pedestrian crossing warrants are followed around the world. Peak hour pedestrian volume “P”
and vehicular volume “V” are two most commonly used factors in these guidelines. PV2 is a criteria, which is used in guideline documents of India,
Iran and UK to identify the need of warranting a particular mid-block location. In India, these guidelines were adapted from UK in 1988 and have
not been revised in the last three decades. These guidelines report a benchmark value, in the excess of which a location should be warranted.
The benchmark values are based on peak flows of 1980s, which have increased drastically over the years. In addition, the guidelines do not
identify the type of crossing facility, which should be provided at a particular location. Therefore, these guidelines need to be revised.
In this paper, PV2 matrices have been developed for a variety of road configurations using the maximum field hourly flows as the upper bounds.
Further, probability distributions have been fitted to the PV2 values. Threshold values have been proposed based on the curvilinear characteristics
of the probability distributions. The revised PV2 values vary from 0.6×108 to 2.1×1011 for different roadway configurations. The ranges formed
using these values have been used to classify the type of crossing facility to be installed using a systematic hierarchical approach. The warrant
charts and PV2 value ranges can be used to identify the need, as well as the most appropriate crossing facility for the site based on the peak
hour pedestrian volume and vehicular volume. The proposed PV2 values and warrants are based on Indian traffic flow conditions. These threshold
values may require modifications for application in any other country.
Pointing Chandra toward the Extreme Ultraviolet Fluxes of Very Low Mass Stars

Published: April 2020

The X-ray and EUV emission of stars plays a key role in the loss and evolution of the atmospheres of their planets. The coronae of dwarf stars later than M6 appear to behave differently from those of earlier spectral types and are more X-ray dim and radio bright. Too faint to have been observed by the Extreme Ultraviolet Explorer, their EUV behavior is currently highly uncertain. We have devised a method to use the Chandra X-ray Observatory High Resolution Camera to provide a measure of EUV emission in the 50–170 Å range and applied it to the M6.5 dwarf LHS 248 in a pilot 10 ks exposure. Analysis with model spectra using simple, idealized coronal emission measure distributions inspired by the Chandra Low Energy Transmission Grating spectra of the M5.5 dwarf Proxima Cen and results from the literature finds the greatest consistency with a very shallow emission measure distribution slope, DEM ∝ T
3/2 or shallower, in the range log T = 5.5–6.5, although this could be an artifact of systematic errors. Instead, cooler, more solar-like differential emission measures (DEMs) with a wide range of slopes were able to match the observations. Within the limitations of systematic errors, model spectra constrained by this method can provide accurate (within a factor of 2–4) synthesis and extrapolation of EUV spectra for wavelengths <400–500 Å. At longer wavelengths, models are uncertain by an order of magnitude or more and depend on the details of the emission measure distribution at temperatures log T < 5.5. The method is sensitive to the possible incompleteness of plasma radiative loss models in the 30–170 Å range for which reexamination would be warranted.
Modeling Rotational Disruption of Grains and Microwave Emission from Spinning Dust in AGB Envelopes
Authors: Tram Le Ngoc , Hoang Thiem , Soam Archana , Lesaffre Pierre , Reach William T.
Published: April 2020

Radio observations of some asymptotic giant branch (AGB) star envelopes show excess emission at frequencies below 100 GHz that cannot be explained by thermal dust emission (hereafter anomalous microwave emission (AME)). Moreover, AGB envelopes are a common place where gas molecules condense to form nanoparticles (e.g., polycyclic aromatic hydrocarbons) and large grains. In this paper, we study whether electric dipole emission from rapidly spinning nanoparticles can reproduce the AME observed toward AGB stars. To properly model the size distribution of nanoparticles in the AGB envelope, we take into account both the increase of nanoparticles due to rotational disruption of large grains spun up by radiative torques and the decrease of the smallest nanoparticles due to rotational disruption driven by stochastic gas collisions. We then perform detailed modeling of microwave emission from rapidly spinning nanoparticles from both C-rich and O-rich AGB envelopes using the grain-size distribution constrained by rotational disruption. We find that spinning dust emission is dominant over thermal dust emission at frequencies below 100 GHz. We attempt to fit the observational data of AME using our spinning dust model and demonstrate that spinning dust can reproduce the observed AME in six AGB stars. Finally, we discuss how microwave emission from spinning dust in AGB envelopes could be observed with high-resolution upcoming radio telescopes such the Next Generation Very Large Array and Atacama Large Millimeter/submillimeter Array Band 1. This would be a major leap for understanding AGB envelopes’ formation, evolution, and internal structures of dust. Observations would help to distinguish the carrier of AME via comparisons of C-rich and O-rich stars, because polycyclic aromatic hydrocarbons (PAHs) are formed in C-rich AGB stars, while silicates are formed in O-rich stars.

Some promising areas of research into the effects of the coronavirus pandemic are outlined. Among them – reflection in the system of sanitary and epidemiological indicators and their numerical values of the characteristics of socio-economic systems; comparative analysis of discrete structural alternatives in the light of the choice of solutions to combat the pandemic and its consequences; adaptation effectiveness of institutions in the context of the relationship of micro- and meso-institutions.
Institutional continuum in the context of the pandemic
Authors: Kurdin Alexander A.
Published: April 2020

The article considers institutional responses to the challenges created by COVID-19 pandemic. The comparison of discrete structural alternatives is one of the most important principles of institutional analysis. It means that policymakers and researchers rely on a countable set of legal options in the course of comparison of different institutions designed to solve one or another problem. COVID-19 pandemic provoked the elaboration of “intermediate” normative solutions, thus changing the legal framework and leading to the formation of the short-term “institutional continuum” instead of the established spectrum of alternatives.

« Dieu est beau, Il aime la beauté »
Authors: Bencheikh Ghaleb
Published: April 2020

« Dieu est beau, Il aime la beauté. » Cet aphorisme bien connu du prophète de l’islam a toujours été au centre des préoccupations métaphysiques avec une inclination esthétique des penseurs, philosophes et théologiens musulmans à travers l’histoire. Lorsque les croyants et, par-delà, les acteurs sociaux l’ont médité et intériorisé dans les contextes islamiques, leurs califes et leurs princes ont bâti une civilisation impériale à l’architecture palatiale. Alors le délabrement moral que donnent à voir le rigorisme salafiste et le fanatisme islamiste se présentent comme une inversion tragique du cours de cette civilisation et des cultures qui la sous-tendent. Aussi, la sortie de crise passera-t-elle par la dimension salvifique de la beauté réappropriée. Elle sera le viatique pour une spiritualité vivante et élévatrice. Elle renouera avec l’humanisme et l’épanouissement du sujet humain.
Choc des armes et littérature
Authors: Clain Geoffroy
Published: April 2020

L’introduction de la guerre hybride, des conflits asymétriques ou la réapparition de la « haute intensité » rappellent que les formes de la bataille sont en perpétuelle évolution. Pourtant, la perception commune du lieu où se déroule cette conflictualité semble figée. Elle oscille entre une posture glorificatrice du champ de Mars, auréolé de mythes, et une position de rejet. L’idée d’une bataille décisive tout autant que les figures cardinales des héros contribuent amplement à entretenir la première version. La seconde a rejeté l’homme de la bataille avec l’avènement des conflits de masse, de l’industrie, plus récemment du sentimentalisme et aujourd’hui de la robotique. Toutefois, ces deux visions ne sont pas exclusives l’une de l’autre. Cet article propose d’observer comment et dans quelles proportions ces deux perceptions du champ de bataille ont été reproduites dans la littérature.

Published: April 2020

The current retrospective, longitudinal study applied Andersen's Behavioral Model of Health Services Use to examine how demographic characteristics (age), available resources (e.g., a caregiver, the Mobile Veterans Program [MVP]) and health needs (e.g., cognitive and physical functioning, depressive symptoms) affect hospitalization and institutionalization outcomes among older adults using the MVP. Fifty-four Veterans (age 55 to 95) participating in the MVP for up to 2 years were examined using hierarchical linear modeling (HLM) and growth curve model. In the final HLM model, each 1-point increase in depressive symptoms was associated with 76% (
p
≤ 0.05) greater risk of institutionalization and 40% (
p
≤ 0.01) greater risk of hospitalization. Each 1-point increase in cognitive functioning was associated with 24% (
p
≤ 0.05) lower risk of institutionalization. The relationship between caregiver burden and hospitalization was attenuated by frequency of MVP visits. Services focused on reducing depressive symptoms may influence health service use and reduce caregiver burden in this population. [

As attendees of orthopedic meetings consider how to integrate presented information into their practice, it is helpful to consider the quality of the data presented. One surrogate metric is the proportion of and changes to presented abstracts that become journal publications. With this study, using the 2010 American Academy of Orthopaedic Surgeons (AAOS) Annual Meeting abstracts, the authors sought to answer the following questions: Did the publications following abstract presentations differ in terms of the conclusions, study subjects, or coauthors? What proportion of abstracts was published? What are the most common subtopics and journals, and what is the most common author country? Keywords and authors from the 2010 AAOS Annual Meeting proceedings program (698 podium and 548 poster abstracts) were searched in PubMed, Embase, and Google Scholar. If a publication resulted, differences in the conclusion, number of study subjects, and authorship between the abstract and the journal publication were tabulated. The proportion of abstracts published, specialty subtopics, authorship country, and journals of publication were collected. At journal publication, 1.7% of podium and 1.7% of poster conclusions changed. Mean number of authors for podium and poster increased significantly (
P
<.001), and 30% of podium and 44% of poster had a change in the number of study subjects. The overall journal publication percentage was 61% (68% podium and 53% poster). The majority of the authors were from the United States. The most common journal was

Construction projects are a combination of high complicated procedures that rarely go with the plan. The greatest dangers projects are the construction since it linked with an extraordinary amount of ambiguity and threat and that because of the business activities nature, procedures, and the outside surroundings. This paper investigates the problems during the pre-construction phase and the optimal solution for this problem by using to algorithm, partial swarm and Gravitational search algorithm. The results show that the construction problems have a severe effect on both time and cost and these problems must be treated immediately and this requires sophisticated techniques by using computer science. GSA and PSO are both used and show excellent results in solving these problems, the GSA algorithm shows better results in both the velocity is taken to find the solutions and in the accuracy. PSO is still a good technique in finding the solution and their future recommendation in making an expert system to find the solution more than one project and their interdependency.

. The flow pattern on the combined effect of a horizontal cylinder and a vertical plate is observed and analysed in this experimental study. The experiment was conducted with a 4 cm outer diameter cylinder arranged horizontally across flow above 2 cm from the bed and a vertical plate of 5 cm placed 9 cm downstream from cylinder surface reference as tilting flume bed surface. The water depth was maintained at 17 cm through a constant discharge of 35 lps in a re-circulating flume. Acoustic Doppler Velocimeter (ADV) was used to store the velocity fluctuation of velocity components and further used as a pictorial frame to understand the turbulence and the turbulent kinetic energy around the cylinder, plate and in between the cylinder - vertical plate. From the pictorial contour diagrams drawn, the velocity vector represents the flow feature over the cylinder and it is found that a horseshoe vortex, developed upstream of the plate, does effect on turbulent kinetic energy formed in between cylinder and vertical plate. The observation and obtained results from present study is compared with a 5 cm horizontal cylinder above 2 cm from the bed and a plate situated on 5.5 cm from cylinder curvature towards downstream.

Diagnostics of the rotor blades of aircraft gas turbine engines at pre-operational stage and later on during repairs is carried out by instrumental methods of non-destructive testing. The requirements for increasing operational reliability and safety of flights require a search for new solutions in assessing the strength of rotor blades at an early stage of damage development. For these purposes, one of the perspective directions is the development of acoustic emission methods. This article represents an experimental setup and a measuring-diagnostic system for assessing the operational reliability of rotor blades by the acoustic emission method. It also discusses the results of testing.

. Landuse changing along the Bidara Cina, downstream of the Ciliwung floodplain deteriorates its environmental quality. Its interactions between the building along the floodplain and the river dynamics can be simulated with Ansys Fluent as a simulation tool. This tool simulates the impact of floods could damage the buildings structure that built in flood zones but are still within the limits of habitable zone permits. Ansys Fluent modelling is using CFD parameters, by creating geometric scenarios that have been physically tested. The geometric behavior observed through the effect of large window openings (Experiment x), namely model 1 with one window and model 2 with 2 windows, then it is analysed by rotating 0°, 30°, 45°, 60° and 90° of the building (Experiment y). The outputs that will be analyse from flood induced the building are (i) flood impact force, (ii) total force of building, and (iii) reduction of flow velocity in building. From the simulation result, it is found that building geometry with larger openings is better at resisting the impact strength of floods and reducing the velocity of flood flows. Furthermore, the graph of flood impact force and the total force of orientation in model 1 and model 2 have a tedency to increase while rotation angle increasing. We conclude that based on building type (Experiment x), the model with one window is most vulnerable model and based on building orientation (Experiment y), the model with orientation 90° is the most vulnerable model, but when viewed based on facade that is exposed to the main stream there is an opening, the orientation of 60° is the most vulnerable model.

This study evaluated the cooling properties of summer cooling towels of different brands by analyzing the moisture management behavior. It was found that all the samples could provide a cooling effect at first contact after being wetted. The samples of Cooldyxm and Ice Towel showed the highest cooling effect followed by the N-rit samples, which was regarded as “fast absorbing and quick drying fabric, whereas Perfect Fitness samples had the poorest cooling effect and was labeled as “slow absorbing and slow drying fabric”. The reason may be explained by the yarn density, fabric structure and thickness.

In this paper, a frictionless contact of a rigid flat-ended indentor on a linear elastic half plane is investigated by taking the influence of surface and couple stresses into account. The surface elasticity and couple stress theories are utilized to form a mathematical model. The Green’s function method together with the equilibrium condition of the indentor is employed to formulate the key equations governing the contact pressure. A collocation technique and a set of available fundamental solutions of a half plane under the surface loading are adopted to determine the unknown contact pressure. Results from a numerical study reveal that the presence of both surface and couple stresses significantly alters the distribution of the contact pressure from that predicted by the classical linear elasticity, and the size-dependent characteristics of predicted solutions are obviously observed when the contact width is comparable to the internal length scales of the surface and bulk materials.

This research aims to investigate the mechanical properties of engineered cementitious composites including compressive strength, splitting tensile strength, modulus of rupture, and load-deflection behavior. In addition, the abrasion test of concrete under water, which is recommended by ASTM C1138, was carried out and its results were compared with the splitting and modulus of rupture test results. Untreated low-cost polyvinyl fibers were used with different volume fractions of 0.5, 1.0, 1.5, and 2.0%. All tests were carried out at the standard age of 28 days. The experimental results showed that the use of 2% of low cost polyvinyl fibers with the engineered cementitious composites led to the increase of the splitting tensile strength and the modulus of rupture by 134% and 287%, respectively, compared to specimens incorporating no fibers. The results showed also that the deflection and the ultimate failure load increases as the fiber content increase.

A novel nickel (Ni) and natural rubber loaded carbon nanofiber branches were prepared by electrospinning process followed by conventional heat treatment processes. This research utilized a one-step carbonization process using electrospun fibers from one-pot solution consisting of Ni, natural rubber cup lump (NR) and polyacrylonitrile (PAN). The as-spun nanofibers were successfully prepared for different types of NR-PAN and NiNR-PAN samples. The obtained nanofibers were stabilized at 260 °C for 2 h and then cooled to room temperature. The stabilized fibers were continued calcined at 900 °C for 1 h under N2 atmosphere. Samples were characterized by Fourier Transform Infrared Spectroscopy (FT-IR), X-ray Diffraction (XRD), and Field Emission Scanning Electron Microscopy (FESEM). NR-PAN sample showed a uniform surface whereas tiny branches were found on NiNR-PAN sample. The carbon nanofiber branches with 48.29 nm diameter were observed on the parent carbon fiber surface with 700-800 nm diameter. Furthermore, only metallic Ni nanoparticles was formed and the average size of Ni nanoparticles calculated XRD result was 14.15 nm. SEM images showed that Ni nanoparticles were well dispersed on CNFs.

After elimination of the Aedes aegypti vector in South America in the 1960s, dengue outbreaks started to reoccur during the 1990s; strongly in Argentina since 1998. In 2016, Córdoba City had the largest dengue outbreak in its history. In this article we report this outbreak including spatio-temporal analysis of cases and vectors in the city. A total of 653 dengue cases were recorded by the laboratory-based dengue surveillance system and georeferenced by their residential addresses. Case maps were generated from the epidemiological week 1 (beginning of January) to week 19 (mid-May). Dengue outbreak temporal evolution was analysed globally and three specific, high-incidence zones were detected using Knox analysis to characterising its spatio-temporal attributes. Field and remotely sensed data were collected and analysed in real time and a vector presence map based on the MaxEnt approach was generated to define hotspots, towards which the pesticide- based strategy was then targeted. The recorded pattern of cases evolution within the community suggests that dengue control measures should be improved.
Spatio-temporal outbreaks of campylobacteriosis and the role of fresh-milk vending machines in the Czech Republic: A methodological study
Authors: Marek Lukáš , Pászto Vít
Published: April 2020

Inspired by local outbreaks of campylobacteriosis in the Czech Republic in 2010 linked to the debate about alleged health risks of the raw milk consumption, a detailed study was carried out. Firstly, scanning was utilised to identify spatio-temporal clusters of the disease from 2008 to 2012. Then a spatial method (geographical profiling originally developed for criminology) served as assessment in selecting fresh-milk vending machines that could have contributed to some of the local campylobacteriosis outbreaks. Even though an area of increased relative risk of the disease was identified in the affected city of České Budějovice during January and February 2010, geoprofiling did not identify any vending machines in the area as the potential source. However, possible sources in some nearby cities were suggested. Overall, 14 high-rate clusters including the localisation of 9% of the vending machines installed in the Czech Republic were found in the period 2008-2012. Although the vending machines are subject to strict hygiene standards and regular testing, a potential link between a small number of them and the spatial distribution of campylobacteriosis has been detected in the Czech Republic. This should be taken into account in public health research of the disease.
