Authors: Aalipour Mehdi , Šťastný Bohumil , Horký Filip , Jabbarian Amiri Bahman
Published: March 2022

Scaling models is one of the challenges for water resource planning and management, with the aim of bringing the developed models into practice by applying them to predict water quality and quantity for catchments that lack sufficient data. For this study, we evaluated artificial neural network (ANN) training algorithms to predict the water quality index in a source catchment. Then, multiple linear regression (MLR) models were developed, using the predicted water quality index of the ANN training algorithms and water quality variables, as dependent and independent variables, respectively. The most appropriate MLR model has been selected on the basis of the Akaike information criterion, sensitivity and uncertainty analyses. The performance of the MLR model was then evaluated by a variable aggregation and disaggregation approach, for upscaling and downscaling proposes, using the data from four very large- and three large-sized catchments and from eight medium-, three small- and seven very small-sized catchments, where they are located in the southern basin of the Caspian Sea. The performance of seven artificial neural network training algorithms, including Quick Propagation, Conjugate Gradient Descent, Quasi-Newton, Limited Memory Quasi-Newton, Levenberg–Marquardt, Online Back Propagation, and Batch Back Propagation, has been evaluated to predict the water quality index. The results show that the highest mean absolute error was observed in the WQI, as predicted by the ANN LM training algorithm; the lowest error values were for the ANN LMQN and CGD training algorithms. Our findings also indicate that for upscaling, the aggregated MLR model could provide reliable performance to predict the water quality index, since the r2 coefficient of the models varies from 0.73 ± 0.2 for large catchments, to 0.85 ± 0.15 for very large catchments, and for downscaling, the r2 coefficient of the disaggregated MLR model ranges from 0.93 ± 0.05 for very large catchments, to 0.97 ± 0.02 for medium catchments. Therefore, scaled models could be applied to catchments that lack sufficient data to perform a rapid assessment of the water quality index in the study area.

Published: March 2022

Lakes, either artificial or natural, are greatly important as a component in their catchments’ hydrology, but also as ecosystem service providers. However, due to climate change, they have begun to face numerous problems with their water quality and quantity. Furthermore, general circulation models (GCMs) show future climate change with a reduction in rainfall and increase in temperature. The aim of the current study is to present an application where GCMs and state-of-the-art hydrological modelling system MIKE SHE/MIKE 11 are combined for assessing the response of a Greek lake in terms of its water balance and water level under climate change. Four general circulation models (GCMs; GFDL-CM3, MIROC-ESM-CHEM, MIROC-ESM, IPSL-CM5A-LR) for the extreme climate change scenario of RCP8.5 were used in the basin of Lake Zazari in Greece as a case study. Results showed that, by keeping the irrigated demands (the main water user) unchanged in the future, the lake exhibited a lower water level for all GCMs, fluctuating from −0.70 to −1.8 m for the mean (min) water level and from −0.30 to −1.20 m for the mean (max) water level. Instead of the above and by preserving the amount of withdraw water n from the lake at a certain percentage of inflows, the irrigated area should be reduced from 54.1% to 64.05% depending on the circulation model.

Published: March 2022

Background: The published rates of catheter-associated urinary tract infection (CAUTI) in Saudi Arabia were derived from single-centre studies or nationally non-representative studies. Objectives: The aim of this study was to estimate CAUTI rates and urinary catheter utilisation (UCU) ratios in 99 Saudi Ministry of Health (MOH) hospitals from all regions. Methods: A prospective surveillance study was conducted in 15 different types of intensive care units (ICUs) between January 2018 and December 2019. The data were entered into the Health Electronic Surveillance Network (HESN) programme. The methods of the US National Healthcare Safety Network (NHSN) and the Gulf Cooperation Council (GCC) centre for infection control were used. Results: During 2 years of surveillance covering 919,615 patient-days and 573,720 urinary catheter days, a total of 965 CAUTI events were identified. The overall MOH CAUTI rate was 1.68 (95%confidence interval (CI) 1.58–1.79) per 1,000 urinary catheter days, and the overall UCU was 0.624 (95%CI 0.623–0.625). CAUTI rates were highest in paediatric medical (5.73) and adult medical (2.02) ICUs. UCU were highest in neurosurgical (0.795) and medical surgical (0.743) ICUs. CAUTI standardised infection ratios across different ICUs in Saudi MOH hospitals were 16% lower than NHSN hospitals, 47% lower than GCC hospitals and 69% lower than International Nosocomial Infection Control Consortium (INICC) hospitals. Urinary catheter standardised utilisation ratios across different ICUs in Saudi MOH hospitals were 15% higher than NHSN hospitals, 9% higher than INICC hospitals and 13% lower than GCC hospitals. Conclusions: The current study is a unique national CAUTI benchmark that can potentially help in the fight against healthcare-associated infection.
PROBLEMS AND SCENARIO STRATEGIES FOR THE URBAN DEVELOPMENT OF VOLGOGRAD IN THE ASPECT OF SUSTAINABLE ENVIRONMENTAL DEVELOPMENT
Authors: Samoylova N. , Kosheleva O. , Kasanova N.
Published: March 2022

The regressing of Volgograd's landscaping has led to a deterioration of the ecological situation in the city. The analysis of the Green Ring of Volgograd is presented in the article. The Green ring is basic element of the green frame of the city. It reveals negative factors that in the near future may lead to its complete destruction. The purpose of the study is to predict the further development of the situation and to create scenario concepts that will preserve the Green Ring, to solve the problems of urban development, to create prerequisites and vectors for sustainable urban development in the ecological aspect. The authors analyze the state and development of the Green Ring in Volgograd. They proposed four scenarios for the further fate of this unique formation. The scenarios are conventionally designated as “regressive”, “recreational”, “innovative” and “promising”. Each scenario is based on the inevitability of absorption of the green belt by urban infrastructure due to the growth of urban development and the expansion of the city's boundaries. However, the further development of this process, depending on the prevailing conditions and the measures taken, leads to polar results. The most pessimistic "regressive" scenario is the complete disappearance of the city's Green Ring in the near future. Other scenarios imply the development of the existing Green Ring as part of the urban infrastructure, the creation of a forest belt duplicating it outside the city limits, as well as the development of ecovillages within the Green Ring, turning it into an economically viable project.

Published: March 2022

The developed hydrophobic complex protective layer based on polymethylhydrosiloxane (PMHS) organosilicons on the top layer of the concrete surface along with hydrophobic characteristics and low ice adhesion strength enable to provide a developed surface roughness that is a direct measure of high traction forces between vehicle tires and road surface pavement, and its applicability in transport infrastructure as one of the inti-icing methods.

Portland cement mortar samples treated with PMHS-based hydrophobic emulsion demonstrated very apparent hydrophobic and icephobic characteristics. The majority of the coated mortar samples reveal over- and superhydrophobicity.

Ice adhesion of the mortars with hydrophobic coatings was 10 times lower in comparison with the reference non-treated hydrophilic samples.

Published: March 2022

Purpose: The present study is aimed to observe the differential response of pranayama in reducing high sensitivity C-reactive protein and creatinine kinase levels among chronic obstructive pulmonary disease patients in comparison to control patients. Material and Methods: An intervention study was done by enrolling 100 chronic obstructive pulmonary disease patients who were managed by therapeutics. The participants were divided into intervention and non-intervention group with 50 each sample. The intervention was in the form of sequenced yogic practices for 6 weeks. The pre-intervention and post-intervention inflammatory maker levels were estimated along with lung function estimation. Results: The result was analyzed by descriptive statistics. The mean C-reactive protein, serum creatinine kinase value decreased from 9.53 to 7.85mg/L and from 145.01 to 140.57 U/L respectively following 6 weeks of yogic practices intervention. The observed values were found to be statistically significant (p=<0.05). Conclusion: The statistically significant reduction in inflammatory makers, C-reactive protein and creatinine kinase level following 6-week yogic practices in chronic obstructive pulmonary disease patient suggests including such yogic interventions in the regular management protocols of chronic obstructive pulmonary disease patients.
Perceived Discrimination and Suicidal Thoughts and Behaviors Among American African American and White Children
Authors: Assari Shervin
Published: March 2022

Background: Perceived discrimination (PD) is a risk factor of suicidal thoughts and behaviors (STB) for children, youth, and adults. However, it is unknown whether the association between PD and STB frequency differs between African American (AA) and Non-Hispanic White children. Objectives: In this study, we compared AA and non-Latino White children for the association between PD and STB frequency in a national sample of 9-10-year-old American children. Methods: This cross-sectional study used data from the Adolescent Brain Cognitive Development (ABCD) study, which included 7883 non-Latino White or AA children between the ages of 9 and 10. The predictor variable was frequency of PDs. Race was the moderator. The outcome variable was STB frequency, treated as a count variable, reflecting positive STB items endorsed over the life-course. Covariates included sex, age, marital status, household income, parental education, parental employment, trauma, and economic difficulties. Poisson regression was used for data analysis. Results: Of all the participants, 5994 were non-Latino Whites, and 1889 were AAs. Overall, PD frequency was positively associated with STB frequency. A statistically significant interaction was found between race and PD, suggesting that the association between PD and STB frequency is weaker in AA than non-Latino White children. Conclusion: The observed weaker association between PDs frequency and STB frequency in AA than non-Latino White children suggests that PD may be a less salient risk factor of STB frequency for AA than non-Latino White children. Researchers should explore factors other than PD for suicide prevention of AA children in the US.

Authors: Bidaki Reza , Mirhosseini Hamid , Zare Nahid
Published: March 2022

Introduction: The motor function is associated with the activity of both the motor and prefrontal cortices. The efficacy of transcranial direct current stimulation (tDCS) over specific brain cortices has been examined in many psychiatric and neurologic disorders. This study aims to report the tDCS effects on two females of advanced age with idiopathic Parkinson’s disease (PD). Case Presentation: We considered 50-minute sessions of bilateral primary motor cortices and left dorsolateral prefrontal cortex (DLPFC) anodal stimulation using tDCS with passive stretching exercises simultaneously for a total of 20 sessions in 7 weeks. Clinical signs and electroencephalography (EEG) waveform were assessed at distinct times. Both of the two patients showed improved motor function for a short time. EEG changes to some extent concerned clinical states. Conclusion: It seems that tDCS can be an auxiliary treatment for motor dysfunction in PD; however, further studies must be carried out to prove the claim.

Published: March 2022

Engineered Cementitious Composite (ECC) concrete or micromechanical modeled concrete using analysis of a mixture of fiber and other added materials can produce a tensile strain capacity of up to three hundred to five hundred times compared to the strain capacity of conventional concrete. A review related to several studies that have been carried out previously on the properties of ECC and their constituent materials is presented in this paper. The behavior of the material is reviewed as an investigation parameter followed by determining the composition of the mixture, namely the effect of the water-cement ratio, the shape and length of the fiber and the addition of additives. The fiber volume fraction review was limited to between 2% to 3%, which resulted in outstanding tensile strain behavior. As it is known, ECC has an excellent capacity in terms of strain behavior which is accompanied by a large number of mico cracking patterns. ECC crack widths are usually predominantly less than 100 μm. ECC behavior is closer to that of steel which can bend or be ductile, whereas conventional concrete is brittle.

Looking back on Nigeria’s COVID-19 School Closures: Effects of Parental Investments on Learning Outcomes and Avoidance of Hysteresis in Education
Authors: Ogenyi Moses
Published: March 2022

In this Insight Note, we explore how COVID-19 and related school closures impacted Nigerian schools, parents, and students. National data collected by the National Bureau of Statistics in 2020 through a monthly phone survey show that children had extremely limited contact with the education system during this time, and that families preferred low-cost alternatives such as in-home tutoring and increased parental involvement in education to e-learning tools. Additional data collected by the RISE Nigeria Team in a survey of 73 low-cost private schools in Abuja suggest that some schools did maintain contact with students during mandated school closures, that students experienced absolute learning losses equivalent to about 5-6 months of school missed in other contexts (Cooper et al, 1996), despite participation in alternative learning activities, and that the pandemic led to severe financial hardships for schools and teachers.

Authors: Elizarev Vladislav V. , Saveleva Elena E. , Pestova Rimma M.
Published: March 2022

Aim to improve the quality of life of patients in the early postoperative period after septoplasty.
Material and methods. The study involved patients who underwent septoplasty (n=51). The patients were divided into two groups: in group A (n=26) classic intranasal splints were installed at the end of the operation; in group B (n=25) we used the modified intranasal splints with an integrated rigid duct, with a pressure distributor placed mainly in the anterior nasal septum and the latches along the periphery (patent No. 191163). To assess the patients comfort before and on the first day after surgery, a quality of life assessment questionnaire (Sino-Nasal Outcome Test SNOT-20) was used. The headache intensity was evaluated in the early postoperative period using a visual analog pain scale. Statistical data processing was carried out using the STATISTICA 12 software.
Results. According to the results of SNOT-20, we obtained a statistically significant (p 0.05) improvement in the quality of life of patients when using our modified splits against the traditional splits. Comparing the data of the SNOT-20 questionnaire and VAS, we found a statistically significant (p 0.05) reduction in pain in the early postoperative period when using our intranasal splints with an integrated air duct and pressure distributor.
Conclusion. The use of our modified intranasal splints improves the quality of life of patients in the early postoperative period.

Published: March 2022

Aim to compare the parameters of bioimpedance analysis of body composition in elderly and old men with polymorbid pathology.
Material and methods. The study involved 123 men aged from 65 to 84 years (mean age 73.7 5.9 years) with polymorbid pathology. The Group 1 included 65 elderly men; the Group 2 consisted of 58 old men.
Results. The study revealed the decrease in strength, mass and muscle function parameters related to aging. The bioimpedance phase angle was lower in the group of old men than in the group of elderly men. The correlations of the phase angle with anthropometric and functional parameters, as well as with body composition were revealed.
Conclusion. The decrease in muscle mass parameters and low phase angle may be associated with degenerative processes in skeletal muscles due to aging and polymorbidity. The bioimpedance analysis of body composition can be used in geriatric practice for the diagnosis of sarcopenia syndrome in elderly and old men.

The present study aimed to determine the prevalence of ADHD diagnosis among the patients applying to adult psychiatry polyclinic for the first time and to determine comorbid diseases among the patients diagnosed with ADHD. The present study was carried out on patients who applied to the Psychiatry Polyclinic in the Medical Faculty Hospital of Kocaeli University Turkey between 10.01.2018 and 03.01.2019, with 151 patients involved in this study. After providing the participating patients with a verbal and written briefing about the study, the Sociodemographic Information Form and AADHDS were given to the participants. DIVA2.0 Adult ADHD Diagnostic Interview Scale and SCID-1 were implemented. As found in DIVA 2.0 ADHD Diagnostic Interview Form for Adults, 19.9% of 151 patients were diagnosed with adult ADHD, and 80.1% were not. Given SCID-1 diagnoses of patients, it was determined that, of the patients diagnosed with ADHD, 16.6% were diagnosed with depression, followed by generalized anxiety disorder (10%), and panic disorder and depression (10%), and that 13.3% of participants were not diagnosed with another disorder. Participants diagnosed with ADHD were found to have lower mean age. Prevalence of ADHD diagnosis was found to be lower among singles and students. The individuals diagnosed with ADHD were found to have a more prolonged education period. The prevalence of ADHD was higher among those who received a disciplinary punishment. Making an accurate diagnosis, designing an appropriate treatment, and determining the comorbidities of ADHD and with which psychiatric disorders it is confused would positively contribute to outcomes of treatments and increase the patients’ quality of life.

One of the reasons for non-compliance with the requirements of regulatory documentation of powdered materials, including drugs is microbiological contamination. The search for alternative technical approaches of bactericidal disinfection using modern physical methods is relevant for research. Checking the compliance of activated carbon «Silcarbon», which is used in medicine as a sorbent, showed that the number of fungi (TYMS) exceeds the permissible norms in several times. A number of experimental studies where ultraviolet light, a combination of UV radiation and ozonation were used have been performed to disinfect «Silcarbon» from microbiological contaminants. It is shown that optimal results can be achieved in terms of the content of molds and yeasts: the total amount does not exceed 70 CFU/g using a combination of UV radiation and ozonation. When using pulsed UV lamps with a flux density of 10000-10500 W/m2, the amount was 30 CFU/g, and for molds fungi 20 CFU/g, which meets the requirements of regulatory documents. In dependance on the method of disinfection use the total amount of microbiological contamination of «Silcarbon» ranges from 50 to 70 CFU/g.
Lattice-based ABE-IBE Proxy Re-Encryption for IoT Systems

Published: March 2022

The recent expansion of the Internet of things (IoT) and its applications continues to dramatically change the IT services supporting manufacturing, energy management, intelligent transportation, smart cities, etc. These IT services often interconnect Internet-based Cloud systems with IoT or intelligent smart devices held by organisations. As IoT devices are resource-limited, the security of their communication is provided by lightweight cryptography that could consequently lead to the devices being insecure against a quantum adversary. On the other hand, Internet Cloud systems are resource-rich and could easily support post-quantum cryptography. This paper presents a proxy re-encryption scheme that translates ciphertexts of a classical lightweight encryption algorithm into their post quantum equivalent and vice versa. More precisely, we propose a lattice-based ABE-IBE (L ABE-IBE) proxy re-encryption scheme that transforms a classical lightweight ciphertext into a lattice based ciphertext. We compare our proposed L ABE-IBE proxy re-encryption scheme with classical proxy re-encryption (ABEIBE) schemes. We discuss the security and efficiency of our construction.
SPAM-DaS: Secure and Privacy-Aware Textual Misinformation Detection as a Service

Published: March 2022

Recent works have highlighted how misinformation is plaguing our online social networks. Numerous algorithms on automated misinformation detection are centered around deep learning~(DL) which requires large data for training. However, privacy and ethical concerns reduce data sharing by stakeholders, impeding data-driven misinformation detection. Current data encryption techniques providing privacy guarantees cannot be naively extended to text inference with DL models, mainly due to the errors induced by stacked encrypted operations and polynomial approximations of the otherwise encryption-incompatible non-polynomial operations. In this paper, we show, formally and empirically, the effectiveness of (1) $L_2$ regularized training to reduce the overall error induced by approximate polynomial activations, and (2) sigmoid activation to regulate the error accumulated due to cascaded operations over encrypted data. We assume a federated learning-encrypted inference~(FL-EI) setup for text-based misinformation detection as a (secure and privacy-aware cloud) service, where classifiers are securely trained in FL framework and inference is performed on homomorphically encrypted data. We evaluate three architectures---Logistic Regression~(LR), Multilayer Perceptron~(MLP), and Self-Attention Network~(SAN)---on two public text-misinformation datasets with some interesting results, for example, by simply replacing ReLU activation with sigmoid, we were able to reduce the output error by $1750\times$ in the best case to $43.75\times$ in the worst case.

The possibility of
creating vacuum robotics based on the polymer structures irradiated by an
electron beam, in particular, polymer fibers, which provide high functional
flexibility and a variety of states, is discussed. The possibility of using
polymer fibers as different types of MEMS-like electromechanical elements is
demonstrated - from elastic cantilevers to springs that change their state
under the electron beam. Experimentally proved the presence of different
functional types of fibers, correlating with their thickness, as well as the
phenomenon of the fiber break. A number of exotic forms of dynamics have been
demonstrated and a method for their detection has been developed using 2D
Fourier spectra, integral spatial characteristics, time rsolved correlograms
and wavelet transforms (visualized as the scaleograms / scalograms). Access barcodes

Caminhos, encruzilhadas, porteiras e feitiços para uma filosofia popular brasileira
Authors: Haddock-Lobo Rafael
Published: March 2022

This article aims to present some reflections on certain aspects presents in the relationship between Brazilian popular philosophy and the macumbas (a set of religious activities that arise from the cross between the cultures of the African diaspora, the knowledge of the original peoples, and the popular Portuguese Catholicism). In this sense, at first, we will start from the notion of experience, which needs to be revisited in the light of popular knowledges in order to rethink the very notion of method. Method, then, no longer thought only as the opening of the path (as Descartes), in which the philosopher shows that there is only one to be followed, but thought from the wisdom of the forests, where the footsteps of the caboclos show us that every path is made for walking. Thus, more than a method, it seems that the question makes us rethink whether it is not “style” that we are dealing with or what we should need to deal with: the way we enchant and chant our spells so that philosophy no longer arrives loaded with the weight of a coloniality that only seems to paralyze us, like prey in front of the predator’s seductive gaze.
Transculturación y sincretismo: una visión holística desde la proyección músico-danzaria en diferentes contextos socioculturales cubanos
Authors: Balbuena Gutiérrez Bárbara
Published: March 2022

This essay addresses the concept of “transculturation” (Ortiz,1983: 90), which responded to an effort by the fruitful Cuban researcher to decolonize the social sciences in the face of the biased Eurocentrist and colonialist theories then spread throughout America. It analyses why the term syncretism was not the essential and defining factor, in the “configuration of Cuban religious cultural complexes” (Menéndez, 2017: 87) of African descent. The notion of transculturation is then applied to the study of the processes of formation of traditional Cuban popular culture, specifically in its current musician-dance projection, from a holistic view and from the different Cuban sociocultural contexts where they manifest themselves: religious, secular and popular. The instrumental ensembles and dance expressions of the main Cuban religious cultural complexes are classified and characterized: the Rule of Ocha-Ifá, the Arará Rule, the Palo Monte Rule, the Abakuá and Vodú societies. Likewise, the rumba complex, traditional congas and comparsas, and social or popular dances, as manifestations of a lay character where the presence of the cultural memory of the nation is perceived in full symbiosis.
Afrocubanismo: algo más que una opción

Published: March 2022

Cuba began XX century with a new decolonial discourse with a representative president, constitution and flag. However sociallly, economically, and politically, the greater Anitlles became one more appendage of Unietd Steates. It is not by chance, then, that renewed interpretations of national expresions germinated, which forms that could be erected the most as emblems of cubaness. Were those standede between what came from Europe and black continent. This is influenced by the presisten culture of resistance and the essence of popular religiosity, whose strategies made it posible to preserve the tradition, even without legalized institution, theorical bodies or established official discourses to simúlate its positioning Afro-Cubanism is here to history and it redefines what decolonial expresión in a renewed dimensión like art or combat discourse.

Introduction: The emergence of antibiotic-resistant organisms is a major public health concern, particularly in hospitals and other health care settings. Carbapenem are a group of β- lactam antimicrobial agents with an exceptionally broad spectrum of activity. They are used as a last resort drug against many multi-drug resistant (MDR) microorganisms such as extended-spectrum beta-lactamase (ESBL), Metallo-β- lactamase (MBL), and AmpC β lactamase enzyme-producing gram-negative bacilli. Aim of the study: The aim of this study was to ascertain the prevalence of MBL-producing gram-negative bacilli in a tertiary care hospital. Materials & Methodology: This Cross-Sectional study was carried out in the Department of Microbiology, Chittagong Medical College and Hospital, Chittagong. During the period of July 2015 to June 2016 after approval of the protocol by the ethical review committee of Chittagong Medical College. Total 220 samples were collected from both sexes and different age groups. The specimens were collected and processed according to the standard methodology. Non-molecular methods were used for the detection of Metallo-Beta-Lactamases producing isolates. Results: MBL producing organisms were 100% resistant to Imipenem and Ceftazidime, 98% resistant to Cefotaxime, Cefepime and Amoxicillin-Clavulanic acid, 94% resistant to Ceftriaxone and Ciprofloxacin, 86% resistant to Gentamicin. 84% resistant to Cotrimoxazole and Aztreonam, 78% resistant to Amikacin and Netilmicin, 34% resistant to Piperacillin-Tazobactam and 22% resistant to Colistin. Conclusions: The high rate of Metallo-Beta-Lactamases producing gram-negative bacteria in this study emphasizes the need for active surveillance in the microbiology laboratories for the detection of these resistant strains and also stresses the judicious use of Carbapenems to prevent the spread of the resistant organisms. The non-molecular method was used to detect MBL.

Emphysematous pyelonephritis (EPN) is a severe form of urinary tract infection with a high mortality unless treated rapidly and effectively. Our objective is to review our experience over 15 years (from 2005 to 2020) on conservative treatment according to clinical, bacteriological, radiological, therapeutic and evolutionary aspects of EPN. We analyzed the medical record of patients treated for EPN at the Urology service of Mohammed the VIth University Hospital of Marrakesh. There were 18 patients with an average age of 54 years. They were all diabetics. Lithiasis obstruction of the upper excretory tract was found in 15 patients (83%). The germs involved were Gram-negative bacilli, especially E. coli (61% in our series) followed by Staphylococci (22.2%), Klepsiella (11.1%), and proteus mirabilis in 5.5% of cases. Resuscitation measures, including antibiotic and insulin therapy, were introduced as a matter of urgency for patients if needed. In 77.8% of cases, treatment was conservative: 11 patients (61.1%) underwent endoscopic drainage with a JJ stents and 3 patients (16.6%) underwent open drainage of peri-renal collections with a nephrostomy tube placement). Only 4 patients (22.2%) patients underwent nephrectomy. No deaths were observed during the course.
