Water Resources Management in Progo River Basin using SWOT Analysis
Authors: Andika Neil , Partarini Ni Made Candra
Published: September 2023

About 3.1 million people use the water from Progo River for domestic use, agriculture, livestock and even for religious rituals which solidifies the importance of Progo River to the residence. However, the characteristics of the Progo River has not been studied well. This paper aims to understand the characteristics of the Progo River and the main threat to the river. To achieve those objectives, a SWOT analysis was used particularly in three segments of Progo River Basin, which is upstream, midstream, and downstream reach. The upstream segment has a basin slope more than 25%, the middle segment has a basin slope of 8-25%, and the downsteam segment has a basin slope less than 8%. The SWOT analysis would be based on desk study, hydrological analysis, water quality analysis and field observation. The upstream segment is characterized by high land erosion rate, steep slope, and the presence of Umbul Jumprit, a holy site for Buddhism. The midstream segment is very close to the residence area which reduces the water quality of the river. Furthermore, some scouring issues and flooding risk have become the main concern in this area. The downstream segment is crossed by several bridges of national roads while also having a gravel mining activity. This activity causes a massive scouring problem to the structures. It is clear that the main threat to the Progo River Basin is volcanic and human activities. For a starter, the government should prioritize the revitalization act in the upstream area which has a great impact on the midstream and downstream areas. Because SWOT analysis from water resources management perspective have never been done in the Progo River Basin, these findings can be served as a foundation for the integrated water resources management in the basin.

Published: September 2023

Due to the development of modern technologies, the number of sources initiating vibrations and noises has significantly increased. A variety of techniques are used to eliminate the negative impact of extraneous noise and vibrations. The article presents the concept of vibration protection, the options and mechanism for selecting coatings, and an overview of the global market for vibration-proof materials. The most common methods of vibration protection are vibration isolation and vibration damping, implemented by using materials with appropriate properties. Vibration isolation of vehicles is carried out by surface treatment with special mastics or coating with substrates as well as with the usage of hydraulic vibration supports. To minimize the impact of vibrations on buildings and structures, special fastenings and suspensions, vibration isolators, supports, soft rolled and sheet materials are used. For vibration isolation of machine tools and precision equipment, separate supports, a layer of elastic material placed between the machine and the foundation, a floating floor on an elastic base are used. The article presents a brief analysis of metal, rubber and rubber-metal vibration isolation supports in the budget, medium and premium price segments. Vibration damping is performed using special plates, which are available on the market in the form of rolled materials and multilayer plates. Vibration-absorbing composite polymer coatings based on thermosetting polymers have become widespread. The industry of Russia and foreign countries has established the production of vibration-absorbing reinforced sheet materials. Russian scientists are also actively developing new types of coatings: gradient polymer composite materials, thermoplastic extrusion films, laminated fiberglass polymers, etc.

Published: September 2023

To improve the accuracy of the output signals of solid-state wave integrating gyroscopes, various options for algorithms to identify mechanical errors of their resonators in the mode of occasionally switched mode of standing waves free run-out are considered. The measured physical parameters selected are: multi-frequency, Q factor and multi-potency, viscosity axes and stiffness axes of gyroscope resonators. Most algorithms are designed for methods of resonator mechanical errors production control and include the following stages: swinging a standing wave in the selected angular direction; circuit cut off of its active excitation; signal recording and analysis within two axes of measuring device; identification of mathematical model parameters for standing waves, recorded in their slowly changing amplitudes. Additionally, to search for stiffness axes, a technique with adjustable gyroscope resonator rotation axis is given. As a mathematical basis for the derivation and justification of the proposed identification algorithms, the necessary theoretical dependencies are given, explaining the processes of formation and processing the internal measuring signals in solid-state wave gyroscopes. As a practical testing of the most common identification technique, a laboratory study of one technological specimen of a quartz hemispherical gyroscope resonator was performed. To measure its free oscillations, a measuring system of the balancing stand was used, with measurement error up to 1% and a means of analog signals measurment, with an error of 0.05% when measuring a DC voltage of 10V. The experiment carried out showed the effective use of electrode excitation lines of standing wave for four angles {0°, 22.5°, 45°, 67.5°}. At the same time, the measurement time at each angular position was 60 seconds, and the sampling frequency of a separate measuring channel was 33,333 Hz. Herewith, each value of the wave variables was identified at 340 periods of resonant oscillations.

Mathematical Models for Nonideal Resonator Digital Twins of Solid-State Wave Gyroscopes
Authors: Shishakov K. V.
Published: September 2023

Various variants of mathematical models for digital twins of solid-state wave gyroscope resonators with mechanical defects is given. The obtained results are designated for gyroscope manufacturing cycle maintenance to improve the quality of the output products. A general model of resonator in a resonant variable was chosen as the basic one. To take into account small residual errors of resonant manufacturing functions of space non-homogeneous distribution of shell thickness were introduced into it together with density and viscosity of material. The obtained full analytical model of wide-range gyroscope resonator employs expansion of its strained shape by the resonant form spectrum oscillations. For the considered resonators with small residual defects comparable to errors of finite-element schemes of modelling programs, resonant modes of their digital twins are to be calculated numerically for axially symmetrical resonator models. And residual errors of the manufactured shape are considered integrally in analytical models by introduction of different frequency and Q-values small parameters. Later, a working model of narrow-range gyroscope dynamics is extracted from the full model, that is presented in different forms depending on the convenience of stated problem solutions. For that purpose, fixed coordinate system axes (resonator stiffness axes, measurement instrument axes and others) were used along with moving axes following the wave process. A transition from model initial notation via fast variables into slow variable models was done, so as to avoid the effect of scheme viscosity in numerical integration programs,. The presented mathematical relations and models is possible may possibly be applied for improvement of in-process control methods and defect diagnosis of resonators to be produced.

Published: September 2023

The present paper considers the optimization methods of box-type thin-wall structures both in terms of materials and in terms of calculation methods. These structures are widely used in transport, construction and other areas. The example of such structures are bodies of buses, trolleybuses, trams, camper vans, train carriages, emergency vehicles, mobile workshops, accommodation facilities and others. At first global and later local optimization for the preset exposure by system analysis, mathematical modelling and IT-technologies were performed. Determination of global target function and optimization criteria, global and local limitations is shown during optimization. Development of a box-type composite thin-wall structure project was suggested including geometric simulation, selection of material components and whin-wall elements composition. For the purpose of comparison application of nature biological organism for combination of composite panel by separation of principal organ systems providing its vital activity: a locomotive, circulatory, inspiratory and etc., was described. It was shown that similarly to an organism a vehicle (non-uniform system) can provide general and local strength and rigidity of structural elements. When composing a thin-wall element, each variant of a panel is considered as a module with its physical and mechanical characteristics. Methods that can be applied to nonuniform structure analysis and formulae to determine the given flexural rigidity of plate and shell elements of “equivalent” uniform material are described further. An example of box-type thin-wall composite structure optimal design was shown. The conclusion with regard to the proposed method of optimal analysis and design of composite thin-wall structures is made by means of system approach.

Published: September 2023

To assess the possibility of using the acoustic emission method in the direction of selecting activators of hydrodynamic processes of rotary apparatuses (machines) for processing liquid media in constrained conditions, experimental studies of hydrodynamic and acoustic effects accompanying two main modes of their application were carried out: the first is operation in the mode of activator frequency cyclic change, the second is operation in the mode of fixed activator rotation frequency. Seven forms of hydrodynamic activators of three types (vane, turbine and disk) and a rotary pulse apparatus applied for disinfection of lubricants were used in the research. Using conventional and high-speed video, the main hydrodynamic effects accompanying the operation of each type of activator were identified, which were compared with the established acoustic effects and measurements of temperature and the Reynolds centrifugal criterion. According to the results of the research, the possibility and limitations of using the acoustic emission method for comparing the effectiveness of activators and modes of liquid treatment in rotary pulse devices in conditions of its turbulent motion are shown. Under constrained operating conditions of activators imitated by the width of the working chamber, an acoustic emission peak never described in literature earlier was revealed, which differs from the noise accompanying the turbulent movement of the liquid. The relationship between the change in the amplitude of the peak of acoustic emission with the rate of change in the rotation of the activators and the rate of pumping the medium through the working chamber of the rotary pulse apparatus is also established. The results obtained can be used to select and compare the form of activators of hydrodynamic processes, as well as to select and maintain an effective mode of disinfection of aqueous solutions.

Published: September 2023

The subject of this article is the development of software and algorithmic software for conduct and result processing automation of full-scale ballistic experiments on ballistic routes. At the beginning of the work, attention is focused on the importance of conducting full-scale flight tests of small unguided aircraft during research and design work on their development and modernization. Various methods of measuring velocity in a full-scale or bench-mounted ballistic experiment are considered. The description of the method used in this work based on the determination of the average speed on the site according to the readings of two sensors and the implementation of this method in chronographs of open or closed type is given. Based on this, it follows the presentation of the essence of the conducted ballistic experiments to determine the aerodynamic characteristics of small-sized aircraft, including the longitudinal force aerodynamic coefficient. The transition from the specified coefficient to the coefficient of drag during the experiment on a ballistic track is justified. A description is given of obtaining an analytical expression based on the law of 'living forces' to determine the drag coefficient of an uncontrolled passively flying statically stable object in a ballistic experiment. An algorithm for conducting a ballistic experiment in 'manual' mode is presented, and the automation elements of this algorithm proposed by the authors are presented. As a justification of expediency, a comparative analysis of the 'manual' and automated variants of the experiment was carried out. The procedure for working with the developed software and mathematical software is described. In conclusion, the verification of the obtained results of the ballistic experiment with the results of digital modeling in the developed software and mathematical complex was carried out.
Secured Clustering Multilevel Underwater Acoustic Networks with Dynamic Routing Discovery (SCDRD) Protocol
Authors: S A Rajshekhar , Biradar Arun
Published: September 2023

Abstract: Due to multiple rising automated industry and combat field applications, researchers have developed a growing interest in the area of Underwater Acoustic Sensor Networks (UASNs) over the previous decade. Extending the lifetime of the energy and the consumption of energy in UASNs are enormous challenges. One of the primary difficulties in UASNs is the development of energy-saving routing mechanisms. In recent days the security of the data collected is the main concern because of widely accessible wireless sensors, because these low-power devices are incompatible with complicated encryption methods. As a result, for multi-hop Underwater Acoustic Sensor Networks (UASNs) with non-replenish able energy resources, lifetime optimization and security are two opposing design concerns. This work introduces an Efficient Energy Clustering with Dynamic Routing Discovery protocol (SCDRD protocol), which addresses two competing difficulties by taking into account several characteristics such as probability random walking and the energy balance control mechanism. The suggested protocol detects that energy consumption in the existing network topology is disproportional to energy deployment, which has an impact on the lifetime of wireless sensor networks. Through a quantitative security analysis, this work proposes a non-uniform efficient deployment technique to handle existing energy resource optimization problems and addresses the security location privacy concern. In all circumstances, the proposed Protocol produces the efficient trade-off between the energy balance and the routing mechanisms, allowing sensor networks to last substantially longer. In addition, the deployment of energy in the non-uniform manner results in the increased network’s lifetime and overall packets sent. The results of proposed work is compared with existing cost-aware routing protocols and outperform the existing protocol with respect to various performance parameters like energy, throughput and delivery ratio.

Published: September 2023

Abstract: Water pumps play a crucial role in facilitating the provision of water for various domestic activities. Nevertheless, the energy consumption necessary for its operation is substantial. Prior studies have investigated the implementation of an automation system utilizing an Arduino microcontroller to conserve electrical energy in a water pump. This system was designed for the purpose of automating plant watering and incorporated ultrasonic sensors to mitigate the risk of overfilling. The present study introduces an affordable Smart Home Monitoring (SHM) system. The current automation system can be enhanced through the incorporation of a water sensor. This addition aims to mitigate the occurrence of vacuum and excessive water in the tank, which arises from imprecise water level calculations conducted by the ultrasonic sensor. Furthermore, this study aims to implement an automated water filling system, which allows users to conveniently monitor the remaining water level in real-time through smartphones utilizing the Internet of Things (IoT) technology. Notably, this approach has not been previously explored by researchers. The assessment of energy conservation achieved through the utilization of a water pump is determined to be 39.2% when employing Smart Home Monitoring (SHM) technology

Published: September 2023

Feed is an essential component in fish farming because it supports the survival and growth of fish. Provision of feed, one of which can be done through the utilization of organic waste. One of the efforts used to improve the nutritional quality of feed ingredients is the fermentation technology using probiotic bacteria. The probiotic microbes used in the fermentation will overhaul the structure of the organic matter and the complex bonds contained in the feed ingredients. This right will lead to an increase in the quality of feed ingredients, and in turn, the product will be easily digested and meet the nutritional needs of fish. Search results in several studies indicate several types of microbes involved in probiotic fermentation, either singly or in consortia. Some of them are derived from the Bacillus, Lactobacillus and Saccharomyces groups. Applying probiotics in the fermentation process of feed ingredients can improve their nutritional quality. Examples of some common feed ingredients used in the fermentation process are coffee husk waste, banana peel waste, peanut shell waste, rice straw and coconut cake.

O encarceramento feminino é permeado por inúmeras problemáticas estruturais e pela ineficiência na garantia de direitos fundamentais e assistência psicológica às mulheres. Neste artigo, analisam-se os efeitos de oficinas de intervenção para a promoção do autoconceito, da empatia e de valores básicos em mulheres encarceradas. Participaram do estudo 56 mulheres, em uma Cadeia Pública, com idades entre 18 e 63 anos (M = 32,23; DP = 9,25). Quinze destas mulheres participaram do programa de intervenção, enquanto que o restante da amostra compôs o grupo controle. Ambos os grupos foram avaliados no período pré e pós-intervenção, por meio da Escala de Autoconceito, o Interpersonal Reactivity Index e o Questionário de Valores Básicos. Notas de campo e a observação participante foram utilizadas para descrever experiências significativas vivenciadas durante os encontros. Não foram encontradas variações estatisticamente significativas nos escores das escalas empregadas, o que pode estar relacionado à necessidade de adequação desses instrumentos para públicos com baixa escolarização. Em contrapartida, avalia-se que o uso de oficinas possibilitou a construção de um espaço pedagógico, com contingências muito distintas do ambiente carcerário, no qual as mulheres foram estimuladas a experimentar suas emoções e sentimentos.
The Proposal for an International Anti-Corruption Court: What Law Should the Court Apply?
Authors: Moiseienko Anton
Published: September 2023

In 2014, US federal judge Mark Wolf proposed the establishment of an International Anti-Corruption Court (IACC) to redress the impunity enjoyed by corrupt officials in some countries. An essential aspect of the IACC’s functioning, should the proposal ever take off, would concern the substantive law that it applies.  Since no international court or tribunal has yet adjudicated the criminal offences of corruption, one cannot learn directly from current international experience, but must reason from first principles instead. In dealing with the overarching question of what law the IACC should apply, one needs to take into account various factors, which this article considers in turn, including: (a) the objectives of the IACC; (b) the (incomplete) international consensus on the definition of corruption; (c) the effect of prosecuting money laundering offences on the IACC’s jurisdictional reach; (d) the risks of deferring to domestic laws of the state where the alleged offence took place; and (e) the implications of the principle of legality, often expressed in the Latin maxims nullum crimen sine lege and nulla poena sine lege.
Prosecuting Corruption Crimes before an International Court: Whither Immunity Rules?
Authors: Van Alebeek Rosanne
Published: September 2023

This article argues that an international anti-corruption court has to respect the functional and personal immunity of officials of states that are not a party to it. If an exception applies to immunity before international courts that prosecute international crimes, this exception does not extend to a court that would prosecute transnational crimes. Since personal immunity rules stand in the way of prosecution of (certain, high-level) kleptocrats in foreign national courts, these rules will also hamper the exercise of jurisdiction by an international court. The article further takes issue with the oftheard proposition that corruption is a purely private act that escapes the reach of the functional immunity rule, concluding that functional immunity considerations require closer study in the context of the plans to prosecute corruption crimes at the international level.

O Transtorno do Espectro Autista (TEA) é caracterizado pela condição de transtorno do neurodesenvolvimento, o que afeta a comunicação e a interação social devido aos comportamentos repetitivos. Logo, esta pesquisa teve como objetivo identificar e descrever sobre metodologias utilizadas no ensino de Química para alunos com necessidades educacionais especiais, com enfoque no autismo, de acordo com a produção científica nacional de 2006 a 2022. Trata-se de uma pesquisa bibliográfica de abordagem qualitativa, que teve como base de informações e dados os sites Scielo e Google acadêmico. Ao todo foram identificados sete trabalhos publicados. Por meio dos dados obtidos, percebe-se que a educação inclusiva busca entender, conhecer e desenvolver métodos de ensino para suprir as necessidades de cada aluno, seja autista ou pessoas com outros transtornos ou deficiências. Também foi possível identificar lacunas a serem preenchidas, tais como a falta de formação de profissionais para lidar na prática sobre a educação inclusiva e suprir as necessidades pedagógicas, visando um aprendizado de qualidade e a falta de investimentos nas infraestruturas escolares físicas e pedagógicas. Mesmo assim, a legislação brasileira tem colaborado para que haja a junção dos conceitos e a regulamentação das práticas inclusivas que abrangem, de modo geral, a educação especial, o ensino regular e as instituições de ensino, sendo elas públicas e privadas. Portanto, na busca de metodologias de ensino alternativas para o atendimento de alunos com necessidades educacionais especiais, em especial TEA, a união da família, médico e escola é fundamental para o desenvolvimento da aprendizagem destes alunos.

Published: September 2023

Apesar de possuir qualidades, o sistema alimentar atual, com sua complexa logística e industrialização, gera malefícios à segurança alimentar por produzir alimentos altamente processados e calóricos, diminuir o acesso a pequenos produtores e ter altos níveis de poluição ambiental (FAO,2018). Procurando uma forma de produção alimentar que seja diferente e mais sustentável, a agricultura urbana se mostra uma alternativa viável, já que ela auxilia no acesso a alimentos nutritivos e seguros, ao mesmo tempo que contribui para a construção de cidades mais verdes (FAO; RIKOLTO; RUAF, 2022). Assim, esse artigo teve o objetivo de procurar alternativas para mitigar esse problema a partir de projetos de arquitetura e urbanismo. Foram compilados 10 projetos que, em suas propostas, colocam a agricultura urbana e a produção de alimentos mais saudáveis como um dos focos principais, com características gerais de dar conforto aos moradores e possuir uma relação sustentável com o meio ambiente. Para tal, todo o artigo é feito em forma de revisão de literatura, analisando dados de artigos científicos, dissertações, teses, sites focados no assunto e relatórios de organizações mundiais que atuam no tema em questão, principalmente buscando dados de menos de uma década. Ao final, se observou que é possível construir projetos arquitetônicos e urbanísticos que contribuam para uma produção de alimento mais sustentável, principalmente no meio das cidades e com o uso da agricultura urbana.

Introduction: Mitigating the stress of graduate medical education has been the focus of residency leadership in the United States. This study examined family medicine (FM) resident and program director (PD) satisfaction with current wellness curricula, including perceptions of availability of resources and emphasis on well-being.
Methods: The Council of Academic Family Medicine Educational Research Alliance administered online surveys to PDs accredited by the Accreditation Council for Graduate Medical Education, US-based FM residencies, and resident American Academy of Family Physicians members from April to May 2021. The present study included an assessment of wellness curriculum implementation using the Wellness Element Count (WEC), a satisfaction rating with wellness programming, and a single question assessing perceived changes in emphasis on wellness during COVID-19.
Results: A total of 242 residents (5% response rate) and 263 PDs (42% response rate) completed the survey. Residents reported lower WEC indicators compared to PDs (P<.001). Overall, 67.8% of resident respondents were satisfied with their program’s wellness efforts, compared to 89.3% of PDs (P<.001). Perceived emphasis on wellness curricula in the program was associated with greater resident satisfaction (OR=2.75, P<.05); less emphasis on wellness was associated with less resident satisfaction (OR=0.15, P<.001).
Conclusions: Residents reported overall lower perceived availability and satisfaction with program wellness efforts compared to PDs, suggesting a disparity between perspectives. Ongoing efforts should be directed at encouraging use of available wellness resources and supporting a culture of well-being.

The article introduces into scientific circulation two archival documents signed by S.A. Esenin, which were not included in “The Complete Works of S.A. Esenin” in 7 vols. (9 books) (1995–2001). These documents are kept in the Moscow City Council fund in the Central State Archive of the Moscow Region and indicate plans to expand the publishing activities of imaginists, namely, the project of opening their own printing house. The main document is a letter with an informal appeal to the chairman of the Moscow City Council L.B. Kamenev signed by Esenin, V.G. Shershenevich, and A.B. Kusikov. An official petition addressed to Kamenev, signed by Shershenevich, Esenin, S.T. Grigoriev, R. Ivnev, and Kusikov, is attached to the letter. Both documents were registered in the expedition of the Executive Committee of the Moscow City Council on December 31, 1921, and are commented on in detail in the article. The content of the discovered letter to Kamenev confirms that there was previously a successful initiative of a similar nature. Among the “illegal” publications of the imaginists is the author’s collection of Esenin “Treryadnitsa,” published in mid-October 1920 under the brand of the non-existent publishing house “Cereal,” as well as three collections with the participation of Esenin — “The Foundry of Words,” “The Tavern of Dawn,” “The Cavalry of Storms,” published in February–May 1920. These discovered documents open previously unknown pages of Esenin’s biography.

Mammals, including humans and mice, employ V(D)J recombination and
somatic hypermutation (SHM) to diversify their immunoglobulin (Ig)
variable region repertoires, while domestic poultry, such as chickens
and ducks, rely heavily on gene conversion (GCV) to achieve this
diversification. Given the differences in the arrangement of Ig gene
loci between chickens/ducks and humans/mice, we posited that the
structural arrangement of the Ig locus might play a pivotal role in
driving the pronounced frequency of GCV in poultry. To test this
hypothesis, we engineered a novel mouse model, Igλ
Igκ DIgL, characterized by the
incorporation of the entire duck IgL gene locus and the simultaneous
absence of the mouse endogenous IgL locus. These transgenic mice
produced chimeric antibodies comprising mouse heavy chains and duck
light chains, thereby offering partial support for B cell development.
However, when subjected to repeated immunization with a variety of
antigens, the humoral immune response in Igλ Igκ
DIgL mice was notably diminished compared to that
in wild-type mice. High-throughput sequencing of IgL repertoires
unveiled distinct differences between Igλ Igκ
DIgL mice and ducks in terms of V gene utilization
frequencies, characteristics of the CDR3 region (CDRL3), and nucleotide
additions at junctions (NP nucleotides). Despite the increased
expression of duck IgL due to the absence of endogenous mouse IgL, the
level of GCV observed in duck IgL of Igλ Igκ
DIgL mice (2.01%) remained significantly lower
than that in ducks (35.3%). These findings collectively indicate that
the structural configuration of the Ig locus may not be a critical
determinant of GCV and provide valuable insights into the mechanisms
underpinning the high frequency of GCV observed in poultry species.
Application of control strategy on double fed induction generator based wind energy conversion system while implementing MPPT control algorithm
Authors: P Sreenivasulu , Hussain Jakeer
Published: September 2023

This article presents a maximum power point control (MPPC) algorithm on
a 5kW doubly fed induction generator (DFIG) based wind energy conversion
system (WECS). The proposed algorithm can generate optimal speed for
wind turbine to harvest more energy from all wind profiles. In this
paper, the tip speed ratio (TSR) algorithm is proposed on rotor side
control (RSC) to extract maximum power by controlling rotor speed and
grid side control (GSC) is regulated to control DC link voltage. Also,
the closed-loop double transfer function of RSC and GSC can be
determined by using a proportional-integral control strategy. The
Matlab/Simulation result show that the proposed MPPT algorithm can
extract maximum power against all types of wind flow conditions.
Gaps in Diagnosing Suspected Infection in Immunocompromised Children with Cancer: A Systematic Review

Published: September 2023

While the survival of children with cancer has improved over time,
infection remains a major morbidity and mortality risk. We conducted a
systematic literature review to determine the unmet needs in diagnosing
infection in immunocompromised children with cancer. The comprehensive
search strategy followed the guidelines established by the Cochrane
Handbook for Systematic Reviews of Interventions and the Preferred
Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) 2020
statement and spanned multiple bibliographic databases and other public
sources from January 1, 2012–June 23, 2022. From 5,188 records, 34
unique pediatric-focused studies met inclusion criteria. This review
highlights the lack of published data on infectious disease testing in
pediatric oncology patients and the need for well-designed clinical
impact and cost-effectiveness studies of both existing and novel
diagnostic platforms. Such studies are necessary to optimize diagnostic
and antimicrobial stewardship, leading to improvement in patient
outcomes.

Background and Objectives: Initially developed as immunosuppressive
agents, mTOR inhibitors are currently used widely in the management of
vascular malformations and tumors. The incidence of infectious
complications in the vascular anomalies (VA) population is not well
defined. The goal of this systematic review was to better define the
types and severity of reported infectious complications in patients with
VAs treated with mTOR inhibition. Methods: This was a systematic review
conducted following PRISMA guidelines evaluating all research articles
focused on infectious complications in patients with VAs treated with
sirolimus or everolimus. Thirty articles including 1181 total patients
and 315 infections (in 290 unique patients) were ultimately included.
Results: The majority of infections were viral upper respiratory (n=137,
54%), followed by pneumonia (n=52, 20%), and cutaneous infections
(n=20, 8%). There were 6 total infection-related fatalities, which all
occurred in patients younger than 2 years. Only 1 case of
Pneumocystis jirovecii pneumonia (PJP) was reported. This was in
an infant with KHE who was also treated with steroids and did not
receive PJP prophylaxis. Almost 1/3 (n=95, 32%) of infectious
complications were graded 3 to 4 according to CTCAE criteria. Details of
patient age, subtype of VA, and timing of infection were lacking from
many reports. Conclusions: Most infectious complications reported in
patients with VA on mTOR inhibitors were viral respiratory infections
and non-severe. Bacteremia, infectious fatalities, and PJP are
exceedingly rare. Future studies are needed to clarify the spectrum of
infectious risks in VA patients and to provide guidance for infection
prevention.
