Agricultural Productivity in El Salvador: A Preliminary Analysis
Authors: Bravo-Ureta Boris E. , Njuki Eric , Palacios Ana Claudia , Salazar Lina
Published: March 2022

The need to enhance food security while reducing poverty along with the growing threat imposed by climate change clearly reveal that it is imperative to accelerate agricultural productivity growth. This paper estimates micro-level production models to identify the major factors that have contributed to productivity growth in El Salvador, including irrigation, purchased inputs, mechanization, technical assistance, and farm size, among others. The econometric framework adopted in this investigation is grounded on recent panel data stochastic production frontier methodologies. The results obtained from the estimation of these models are used to calculate Total Factor Productivity (TFP) change and to decompose such change into different factors, including technological progress, technical efficiency (TE), and economies of scale. The findings imply that efforts are needed to improve productivity in both technological progress and technical efficiency where the latter is a measurement of managerial performance. This in turn indicates that resources should be devoted to promoting the adoption and diffusion of improved technologies while enhancing managerial capabilities through agricultural extension.
Проблемы и вызовы водородной энергетики
Authors: Арутюнов В.С.
Published: March 2022

Для существенного снижения глобальной эмиссии СО2 за счет использования в качестве энергоносителя водорода его производство должно достигать не менее 1 млрд т/г. Такой объем водорода не может быть получен за счет возобновляемых источников энергии, гидроэнергетики или атомной энергетики. До промышленного освоения энергии термоядерного синтеза единственным реальным источником такого объема водорода может быть только конверсия природного газа. Поэтому наиболее эффективный способ снижения углеродного следа энергетики – повышение эффективности использования углеводородов, в том числе их конверсии в водород. Как энергоноситель водород обладает серьезными недостатками:низким объемным содержанием энергии, большими затратами энергии на его получение, сжижение и компримирование, высокой взрывоопасностью. На начальном этапе развития водородной энергетики наиболее реальный путь преодоления сложных проблем транспортировки и хранения водорода – его рассредоточенное малотоннажное производство непосредственно в местах потребления.

Key trends in modern Translation Science: Paradigm Shift
Authors:   Ural State Pedagogical University, Alekseyeva Maria L.
Published: March 2022

The research paradigmatics of current translatological studies is heterogeneous. The aim of this article is to provide a brief outline of different research paradigms, major concepts and theories in the countries of Eastern, Western Europe and Russia. Numerous translation researches carried out within the linguistic approach from the 50s until the 90s have not lost their relevance. The latest studies of the early 21th century show a shift in emphasis from the language system towards speech, text as a speech implementation of language and increased attention to the activities of the translator. These studies complement the linguistic approach, indicating growing trends towards text-centrism and anthropocentrism. Trends in the synthesis of scientific knowledge are expressed in the attempt to combine the ideas of text-centric and anthropocentric approaches into a single whole within the framework of the activity paradigm understanding translation as an activity
Foreign Direct Investment and Economic Growth in South Africa: On Direction of Causality
Authors: Maduku Harris , Zerihun Mulatu F
Published: March 2022

The foundation of this paper is built on the premise that foreign direct investment (FDI) follows economic growth and development as opposed to the narrative that argues otherwise. Considering that background, this paper pursued finding the direction of causality and the kind of relationship that exists between the two main variables of interest (FDI and Economic growth) using time series data spanning 1980–2018. Using the vector-autoregressive error correction mechanism and the autoregressive distributive lag, our paper found neither uni nor bidirectional causality between economic growth and FDI in South Africa. The findings support the notion that FDI follows growth and development as opposed to the current policy stance that seeks to attract more FDI without exhausting the potential carried by domestic firms in stimulating economic growth. The results from Granger causality tests, however, could not reject the null hypothesis of the causality that runs from unemployment to economic growth. The study found that unemployment in South Africa Granger causes economic growth significantly. Recommendations arising from our findings are that South African policymakers may need to consider paying more attention to inward-looking policies. More efforts if possible should be put toward making sure that domestic investment is stimulated through making it cheaper especially for small businesses to secure funding as well as making the investment environment small business-friendly to improve their success and contribution toward sustainable economic growth.
Dimensions of Snowsports Education: A Review of Literature
Authors: Pighetti Joshua , Mateer Timothy J. , Allison Pete
Published: March 2022

Snowsports education is crucial to the sustainability of the snowsports industry as it connects the participants to the sport through formal instruction. Investing in the development of snowsports education professionals that have the skills and knowledge can contribute to creating lifelong participants. The purpose of this study is to understand what is known about snowsports education in an effort to guide future research towards a more thorough theoretical, practical, and interdisciplinary understanding. Through a scoping review, this paper summarizes the current body of knowledge and identifies gaps in extant literature. Primary findings suggest snowsports education programs and instructors have significant impacts on a participant’s attitude toward snowsports and toward their skill acquisition. A notable gap is that while researchers have suggested instructor-participant interactions are valuable to the snowsports education experience, few studies have explicitly explored such interaction. Guided by the current knowledge and existing gaps, potential research opportunities are discussed.

SMISAO OBRAZOVANJA U RUSOOVIM DELIMA
Authors: TODOROVIĆ KRISTINA
Published: March 2022

Autor nastoji da ovim radom pokaže da se Rusoovo razumevanje obrazovanja u velikoj meri poklapa sa prosvetiteljskim idejama XVIII veka. Ruso se, zajedno sa ostalim enciklopedistima, zalagao za ideju emancipacije uma od autoriteta, i širenje znanja iz različitih oblasti nauka, filozofije, umetnosti, kao i znanja različitih zanata. Verovali su da će napredak u znanju doprineti i napretku društva. Međutim, Ruso se usudio da posumnja u ove ideje, zbog čega će biti nepravedno optužen da je od njih i odustao. Autor nastoji da u radu dokaže da je Rusoovo odstupanje od ovih ideja samo prividno, i da se njegova koncepcija prirodnog vaspitanja i obrazovanja uklapa u prosvetiteljske ideje. Kako bi dokazao ove tvrdnje, autor će koristiti metodu analize i komparacije Rusoovih tekstova sa tekstovima njegovih savremenika, kao i nekoliko relevantnih istraživanja autora koji se bave ovim i sličnim temama. Cilj ovog istraživanja je prikazivanje drugačijeg tumačenja Rusoovih ideja obrazovanja i vaspitanja, u odnosu na to kako su ih razumevali njegovi savremenici.
KRITIKA I NAJVIŠI INTERES UMA KOD KANTA
Authors: JEVTIĆ NEVENA
Published: March 2022

Autorka polazi od toga da kritika čistog uma kod Kanta nije svodiva na epistemološko istraživanje. Iako je usmerena na saznanje, i to paradoksalno na „saznanje pre saznavanja“, sudeći prema osnovnim motivima Kantove filozofije spekulativni interes ne bi mogao da bude poslednja reč kritike. Rad prvo daje nacrt Kantovog shvatanja interesa, čistog interesa, te mogućnosti subjektivnih efekata koji se vezuju za praktički um. Zatim se preko Kantove teze o primatu praktičkog interesa analiziraju osnovne postavke transcendentalne dijalektike i posebno problema antinomija. Na taj način se konkretizuje i obrazlaže Kantova teza o tome da su problemi spekulativnog uma izazvani interesima praktičkog. Konačno, razmatrajući značaj metafizike za kulturu uma i ulogu kritike u tom kontekstu, rad zaključuje s mogućnošću shvatanja kritike kao modernog propensio intellectualis koje izrasta u skladu sa praktičkim interesom uma.
ЛАЈБНИЦ И SOUVENIR VIRTUAL
Authors: ОСТОЈИЋ АЛЕКСАНДАР
Published: March 2022

Рад настоји да испита Лајбницов концепт виртуалне меморије, те да одреди њену улогу унутар монадолошке концепције света. Лајбницов појам меморије је свакако вишезначан, што ће се у раду увидети, кроз експликацију места у Лајбницовим текстовима, на којима је меморија различито одређена. Прецизније, видећемо да Лајбниц разликује различите функције унутар појма меморије и да их у складу са тим различито и именује, а да су ипак сви они обухваћени унутар виртуалне меморије која чини како онтолошки, тако и епистемолошки основ Лајбницовог универзума. У првом делу рада изложићемо начелне монадолошке поставке, те разлоге због којих виртуална меморија има великог удела у њима. Затим ћемо испитати места на којима Лајбниц пише о меморији, настојећи да их, поред разлика које постоје између тих одређења, објединимо унутар нашег разумевања виртуалне меморије. Да би се истакао значај новина које Лајбниц уноси у разумевање овог феномена, биће неопходно ставити такво разумевање наспрам традиције, унутар које ћемо се фокусирати на Аристотела. На крају, видећемо зашто је таква поставка меморије, коју претпостављамо, нераздвојна од свих видова увећања знања код Лајбница, односно представља нужну структуру на којој се знање темељи.
UNIVERSAL PRINCIPLES IN POLITICAL PHILOSOPHY OF DANTE ALIGHIERI AND IMMANUEL KANT
Authors: METTINI EMILIANO
Published: March 2022

Ideals of universal power able to manage and solve social and ethical (religious) questions as many ways to reach the highest wisdom, and consequently, fullest well-being of humankind to reach a perpetual peace are present throughout human history so that we can find these ideals in Plato’s Republic, in Aristotle’s Politeia and other works concerning the establishment of more or less utopic “states” and commonwealth since our days. In the present essay we shall scrutinize the universalistic vision of Italian thinker Dante Alighieri (1265–1321) and the cosmopolitan idea of German philosopher Immanuel Kant (1724–1804). We decided to analyze the political philosophy of those thinkers on the following grounds: on one hand, D. Alighieri took as the basis of his rumination Roman Empire that having as solid basis of its universalistic ideology Right of every Roman citizen (lying on the observance of religious and civil obligations), and the so-called pax romana[1], a theoretical ground on which D. Alighieri would create a communitas a secular led by Reason commonwealth, which might have replaced the so-called humanitas (in Augustinian understanding of such idea); and, on the other hand, I. Kant tried to explain how human self-improvement under the right use of Reason (that we understand like ethical ruling principle of humankind) can be achieved to lead human beings from the state of nature (a semi-brutal one) to the state of reason, which would have as final end a perpetual peace in a universal republic. On those bases we shall try to detect common theoretical and ideal features between D. Alighieri and I. Kant’s vision, so to prove that universalistic power is not a despotic power, but a unifying power under ethical and spiritual principles of the whole humankind.

 

[1] The Pax Romana (Latin for "Roman Peace") is a roughly 200-year-long time span lasting from accession of Caesar Augustus, founder of the Empire (27 BC) to the death of Marcus Aurelius (180 AD) identified as a period and golden age of increased as well as sustained Roman imperialism, order, prosperous stability, hegemonial power and expansion, despite several revolts and internal political riots.

Published: March 2022

Rad predstavlja nastavak analiza Gadamerove rehabilitacije pojma mimezisa koji nosi celinu njegovog projekta filozofske hermeneutike. Oslanjajući se na rezultate analiza provedenih u prethodnom radu ovaj članak u konačnom tvrdi da je kod Gadamera na delu opetovanje, a ne ponavljanje mimezisa, te ukazuje na nužnost napuštanja pojma istine ukoliko se zaista želi izvršiti ponavljanje mimezisa i izaći iz začaranog kruga platonistički postavljene igre zarobljavanja mimezisa.
REFLEKSIJA I SPEKULACIJA
Authors: JEVTIĆ NEVENA
Published: March 2022

U ovom radu, autorka će predstaviti Hegelove pojmove refleksije i spekulacije onako kako su razvijani u njegovom spisu Razlika. Refleksija i spekulacija, kao međusobno povezane i uslovljene misaone procedure, u stanju su da ispune dvostruki zadatak kritičkog uvođenja i sistematskog razvijanja filozofije. Kao radikalno zahvatanje u antinomije refleksije, zapravo izvođenje antinomija iz samog apsolutnog identiteta, samo-kritička refleksija jeste metoda onoga umskog ili spekulativnog. U manuskriptu Hegelovih predavanja iz 1804/5. godine, Logika – metafizika – filozofija prirode, na primeru logičkog izvođenja vrsta sudova vidljiva je samokritika refleksivnih misaonih odredaba na delu. Ovaj rani koncept logike, koju Hegel naziva logikom refleksije ili logikom razuma, igra ulogu uvoda u metafiziku.
RASTJELOVLJENJE LJUDSKOGA. O (ID)ENTITETU TRANSHUMANISTIČKOG SUBJEKTA
Authors: SINGBO ODILON-GBÈNOUKPO
Published: March 2022

Transhumanizam kao filozofski pravac pomoću znanstveno-tehničkih dostignuća promiče, među ostalim, produžavanje ljudskog života kroz oslobođenje manjkavosti kojima je ljudsko tijelo obilježeno. On znatno utječe na poimanje ljudske naravi stvarajući okvire za paradigmatsku promjenu pogleda na tijelo. Tijelo prolazi kroz konceptualno-teorijske i tehničko-praktičke transbiomorfoze s ciljem ispunjenja svih potencijala subjekta u duhu morfološke slobode. Na taj je način otvoren put k dolasku ekstropijskog subjekta koji bi napredovao po dinamici neprekinutog razvoja. Želja za nadmoći nad prirodnim datostima proteže se kroz kontrolu tijela podvrgnutog raznim hibridnim praksama. Ovdje transhumanističko self-made-man načelo pokazuje instrumentalni i idealizirajući odnos subjekta prema vlastitom tijelu. Takvo načelo traži temeljito promišljanje o ljudskome kako bi se raskrinkali identitetski temelji idealnog i savršenog subjekta koji se želi pokazati kroz novo i poboljšano tijelo. Transhumanistička potraga za novim i savršenim bićem postaje izazov filozofsko-teološkom poimanju ljudskog tijela.
THE LEGAL AND ETHICAL ASPECTS OF THE USE OF LETHAL AUTONOMOUS WEAPON SYSTEMS IN WARFARE
Authors: KELAM IVICA , NEDIĆ TOMISLAV
Published: March 2022

The development of new technologies has always found its first application in warfare, from the invention of the bow and arrow, through the discovery of gunpowder, to the use of unmanned aerial vehicles in the “War on Terror.” The “successful” use of drones in the targeted killings of “terrorists” gave additional impetus to the development of new types of autonomous weapons that completely replace soldiers of blood and flesh on the battlefield. Currently, there is significant controversy over fully autonomous weapons that are fully autonomous in carrying out military operations. They can autonomously decide on the use of deadly force against “enemy” human beings. This kind of autonomy causes numerous controversies, not only legal but also ethical. Moreover, it calls into question the very essence of man, i.e., whether the “killer robot” is the next evolutionary stage in the development of the human species or a technological return to barbarism. This paper will analyze some of the above legal and ethical dilemmas that await us in the near future.

This literature review aims to analyze problems associated with children's communication in the context of school education. The following factors were found to be related to the problem of communication: language skills, motor skills, visual and visualspatial perception, visual memory, auditory-motor and visual-motor coordination, the level of motivational readiness for school, poorly organized activity, which is associated with the immaturity of the regulatory structures of the brain, and are closely related to school maladaptation. The problem of attention deficit hyperactivity disorder is emphasized. We also described the factors affecting the formation of communication at school. We provided the criteria for defining the term ‘communication’ according to the International Classification of Functioning, Disability and Health (ICF) Conclusion. The child should have well-developed communication skills to assimilate the information received and acquire necessary social skills. Any problems with this interaction lead to school maladaptation. The school environment for children with limitations associated with communication should be equipped with special technical devices that address the issues of improper perception and transmission of information, promote the development of communication skills, expand the sphere of communication, and integrate the child into public life as much as possible. Key words: children, school age, limitations of activity, ability to communicate

Being one of the main causes of renal failure in children, hemolytic uremic syndrome (HUS) is a significant therapeutic challenge for pediatricians. Limited epidemiological data on the incidence and prevalence of HUS in the pediatric population suggests the need for studies in this area. Objective. To assess specific clinical characteristics of HUS in children residing in Tyumen region, analyze diagnostic approach used in this region, and identify the main effective therapeutic regimens. Materials and methods. We performed retrospective analysis of 33 HUS cases. In the majority of them, symptoms of acute renal failure were preceded by an episode of diarrhea with hemocolitis, while their disease progression manifested with extrarenal complications involving the cardiovascular system, nervous systems, and gastrointestinal tract. Laboratory testing demonstrated signs typical of thrombotic microangiopathy, which is considered as an underlying pathological mechanism of HUS: Coombs-negative hemolytic anemia, thrombocytopenia. Acute kidney damage was confirmed by hyperazotemia and proteinuria. Differential diagnosis of typical and atypical HUS was based on the measurement of ADAMTS-13 level and testing for Shiga toxin. Results. Instrumental examinations confirmed renal failure and extrarenal complications. In the majority of patients, first-line therapy included renal replacement therapy, plasma transfusion, and hemotransfusion. Patients with verified atypical HUS received the complement inhibitor Eculizumab. Since new diagnostic tests are not available everywhere, it is necessary to consider an organizational decision regarding testing according to indications activity ADAMTS-13 and the administration of complement-inhibiting drugs as first-line therapy for atypical HUS. Key words: hemolytic uremic syndrome, dialysis, monoclonal antibodies, renal failure, ADAMTS-13

We report a case of tracheal agenesis complicated by multiple malformations of the respiratory, digestive, and urinary tracts in a preterm baby who required specialized emergency care rom the first minutes of its life and survived for 53 days. The aim of this case report is to provide a detailed description of the diagnosis and treatment stages in this patient and demonstrate possible errors and tactical approaches to surgical correction of tracheal agenesis. Because of the fact that this disorder is exceedingly rare and was combined with other malformations, its main symptom, pronounced respiratory insufficiency, is not usually considered as a result of upper respiratory tract lesions. The majority of patients are diagnosed post-mortem. Moreover, the vascular graft forming the frame of the newly created trachea allows stable independent breathing for quite a long time in patients with tracheal agenesis. Key words: tracheal agenesis, respiratory failure, multiple malformations, preterm newborn, vascular graft

One of the obstacles faced by the broiler farmer breeders is the high price of feed, which can cause low profits obtained in the broiler chicken farming businesses. An alternative is to use fermented Lamtoro (Leucaena leucocephala) leaf flour. The purpose of this study was to examine the effect of partial replacement of a commercial ration with fermented Lamtoro leaf flour. This study was carried out according to a completely randomized design with five treatments and four replications for each treatment, in which each experimental unit consisted of five-day-old chicks. The treatments were L0 (100% commercial feed), L1 (95% commercial feed + 5% fermented Lamtoro leaf flour), L2 (90% commercial feed + 10% fermented Lamtoro leaf flour), L3 (85% commercial feed + 15% fermented Lamtoro leaf flour), and L4 (80% commercial feed + 20% fermented Lamtoro leaf flour). The results showed that the substitution of the commercial rations up to the level of 20% had no significant effects (P>0.05) on all parameters tested (final body weight, carcass weight, carcass percentage, and percentage of chest, thigh, or back). From this study, it can be concluded that fermented Lamtoro leaf flour can replace the use of the commercial ration of broiler up to 20%.

For small-scale beef cattle farmers, capital is one of the main inhibiting factors in developing their farming. Teseng is one of the local wisdom which is a solution for providing capital for small-scale farmers. This study aims to determine the effect of the socio-economic characteristics of breeders on the adoption of Teseng. The research was conducted in Mattirowalie Village, Libureng District, Bone Regency, which is one of the areas in the development of the Teseng system. The number of samples was 76 breeders consisting of 61 farmers who did not adopt Teseng and 15 breeders who adopt Teseng. The independent variable consists of perceptions of capital availability (X1), land area (X2), number of livestock (X3) and age of farmers (X4). The dependent variable is the adoption of Teseng. The regression model used was logistic regression because the dependent variable was a dichotomous variable (1 for adoption and 0 for no adoption of Teseng). The results showed that the factors that influenced the adoption of Teseng were land area (P<0.01) and the number of livestock (P<0.05). Perception, age and number of families did not have a significant effect on Teseng adoption. To increase the adoption of Teseng, the ability of breeders to provide feed both from the existing land and from the provision of alternative feed needs to be developed.
How economics forgot power
Authors: Mallorquin Suzarte Carlos
Published: March 2022

El artículo discute una reciente publicación de un libro de Philip Pilkington, en el cual se propone de manera innovadora una conceptualización del proceso de inversión (acumulación) y crecimiento económico. La mirada crítica a partir de la cual se examina el libro subraya ciertas similitudes teóricas que podemos encontrar en el discurso económico en América latina durante la década de 1950, generalmente denominada en el medio académico anglosajón o europeo como “estructuralismo latinoamericano”, cuya perspectiva central es el examen de las formaciones económicas, así como sus agentes, productos de la configuración de las asimetrías de poder.
Análisis del gasto corriente en los municipios rurales de Michoacán, México, 2001-2015.
Authors: Colín Martínez René , Herrera Torres Hugo Amador
Published: March 2022

El presente artículo intenta mostrar, calculando el efecto valor de origen, que el gasto corriente de los gobiernos de los municipios rurales del estado de Michoacán, México, es más elástico cuando se financia con transferencias federales que cuando los recursos provienen de fuentes propias. En los municipios rurales de Michoacán la proporción gasto corriente respecto a egresos totales es mayor que la relación de ingresos propios respecto a ingresos totales. En el artículo se plantea que el camino hacia la solución está en incrementar los recursos de fuentes propias a través de la innovación interna de las mismas municipalidades en materia de recaudación local, y a largo plazo en aumentar las potestades tributarias locales. Por sus características, no es prudente regular la proporción de gasto corriente financiado con recursos propios,

Published: March 2022

La importancia de las franquicias y empresas familiares en la economía es indiscutible; sin embargo, hay pocos estudios enfocados a valorar la asimilación de sistemas de planeación empresarial (ERP, por sus siglas en inglés), en lo particular, en el lector restaurantero. Esta investigación busca determinar si la relación entre el uso del ERP y el desempeño económico es distinto entre las franquicias y las empresas familiares. En el análisis se utiliza la información de una muestra de 70 franquicias y 102 empresas familiares mexicanas. Este estudio resalta diferencias significativas entre ambos tipos de empresas. Cabe mencionar que, independientemente del tipo de negocio de que se trate, lo que arroja un mejor resultado en ambas muestras es la presió n competitiva del uso del ERP por sus competidores y el papel que juega la transferencia de conocimiento.

El objetivo de este trabajo es presentar un análisis respecto de los principales problemas del sectoragrícola en México en dos periodos clave. Uno que va de 1940 a 1983 y otro que cubre los años de 1984 a 2017. Esta periodización permite ubicar los cambios más relevantes entre lo que fue la estrategia de autosuficiencia alimentaria y la crisis actual de la agricultura mexicana, la cual se caracterizada por dos fenómenos. Por una parte, el predominio de grades empresas articuladas a la comercialización internacional de productos de exportación y, por otra, la existencia de un amplio número de productores rurales viendo en condiciones de precariedad y cuya sobrevivencia depende del mercado interno. El análisis presentado permite proponer los elementos que una política pública agrícola debería incluir con el objetivo de enfrentar la problemática en el campo y avanzar hacia la soberanía alimentaria.

The Effect of Femoral Nerve Block Versus Adductor Canal Block on the Quality of early Recovery after Revision Total Knee Arthroplasty, a retrospective Study
Authors: AlJa'bari Aboud , Sheikh Khalid AL
Published: March 2022

Background: Multimodal pain analgesia strategies are common in perioperative management of total knee arthroplasty (TKA), although the role of adductor canal blocks (ACB) versus femoral nerve block on early postoperative recovery for revision knee surgery is not investigated.Aim: The purpose of this study is to independently evaluate the effect of ACB on short-term postoperative outcomes including (1) length of stay (LOS), (2) postoperative narcotic utilization, and (3) function with physical therapy in revision TKA.Methods: We retrospectively identified a cohort study of consecutive 40 patients from January 2021 to July 2021 who had undergone unilateral revision TKA using a single-shot ACB (19 patients) vs femoral nerve block (21 patients) under spinal anesthesia (hyperbaric 0.5% Marcaine 2.5 ml and 20 microgram fentanyl) in addition to a standardized multimodal pain analgesia protocol. These 2 groups were compared using independent sample t-tests with primary end points of interest being distance ambulated after surgery, and inpatient narcotic use.Results: Quadriceps strength was better preserved in adductor group than in femoral group. Walking meters and going upstairs were better results in adductor group. IV morphine consumption within the first 48 hours period were less in adductor group comparing to femoral group. Conclusion: Adductor nerve block showed better early recovery in revision TKA when comparing to femoral nerve block (FNB).

Cardiac involvement is a common but often subclinical phenomenon in idiopathic inflammatory myopathy (IIM). Cardiac magnetic resonance (CMR) is a promising tool for detecting cardiac involvement in IIM patients. In the present study, we assessed cardiac involvement in IIM patients using CMR feature tracking (CMR-FT). This was a retrospective study in which 37 IIM patients and 25 healthy controls were enrolled. The left ventricular (LV) functional parameters such as volume and ejection fraction (EF) were measured. Global and regional LV peak strain (PS) in radial, circumferential, and longitudinal directions were derived from cine images. Left atrial (LA) volume, longitudinal strain and strain rate (SR) parameters, LA reservoir function, conduit function, and booster pump function were also assessed. IIM patients with preserved LVEF showed significantly reduced global and regional LV PS in the longitudinal direction (all p < 0.05). Also, abnormal LA reservoir and conduit function were observed in IIM patients (p < 0.05). We found that global LV longitudinal PS was an independent predictor of IIM. Pearson’s correlation analysis further revealed that the LV global radial, circumferential, and longitudinal PS in IIM patients significantly correlated with LVEF (r = 0.526, p < 0.001 vs. r=-0.514, p < 0.001 vs. r=-0.288, p = 0.023). CMR-FT-based LV and LA performance can early reveal cardiac involvement in IIM patients with preserved EF.

Published: March 2022

Background: Maternal mortality is still a major challenge to health systems, while the severe maternal morbidity is the primary reason. Our study was aimed to determine whether severe maternal morbidity is effectively predicted by a newly proposed Modified Obstetric Early Warning Score (MOEWS) in the setting of an obstetric intensive care unit (ICU).Methods: A retrospective study on pregnant women admitted to the ICU from August 2019 to August 2020 was conducted. The MOEWS was calculated 24 h before and 24 h after admission to the ICU, and the highest score was taken as the final value. The aggregate performance of the MOEWS in predicting critically ill patients was evaluated and finally compared with that of the Acute Physiology and Chronic Health Evaluation II (APACHE II) score.Results: A total of 352 pregnant women were enrolled; 290 cases (82.37%) with severe maternal morbidity were identified, and 2 of them died (0.57%). The MOEWSs of patients with serious obstetric complications were significantly higher than those of patients without serious obstetric complications [8(6, 10) vs. 4(2, 4.25), z = -10.347, P<0.001]. The sensitivity of the MOEWS was 99.31% (95% CI, 98-100), the specificity was 75.81% (95% CI, 63-86), the positive predictive value (PPV) was 95.05% (95% CI, 92-97) and the negative predictive value (NPV) was 95.92% (95% CI, 86-100). The areas under the receiver operator characteristic (ROC) curves of the MOEWS and APACHE II score were 0.917 (95% CI: 0.878-0.955, P<0.001) and 0.697 (95% CI: 0.629-0.764), respectively.Conclusion: The newly proposed MOEWS has an excellent ability to identify potentially at-risk patients early, and it is more effective than APACHE II. It will be a valuable tool for discriminating severe maternal morbidity and ultimately improve maternal safety.Trial registration: This is not a clinical trial rather a quality improvement project. It will be registered retrospectively.
