Neutrophil to Lymphocyte Ratio on Admission to Predict Mortality of COVID-19 Elderly Patients
Authors: Fenty Fenty , Sukorini Usi 
Published: May 2024

Severe Acute Respiratory Syndrome Corona Virus Disease-2 (SARS-COV-2) is the cause of COVID-19, which led to a global pandemic and high mortality rate, especially in elderly patients. The declining immune system in elderly patients and comorbid diseases lead to more severe symptoms and an increased mortality rate. Many studies have shown that a high Neutrophil-Lymphocyte Ratio (NLR) value can predict the severity and mortality of COVID-19. However, studies on NLR in elderly patients in Indonesia have rarely been conducted. This study aimed to determine the role of NLR on admission as a mortality predictor in COVID-19 elderly patients who underwent in-hospital treatment. This research is an analytical observational study with a retrospective cohort method conducted in Bethesda Hospital, Yogyakarta, Indonesia. The research subjects were selected from July 2020 to October 2021 according to inclusion and exclusion criteria. Inclusion criteria were all elderly COVID-19 patients with an age limit of > 60 years old who had complete hemogram data on admission, demographic data, diagnostic criteria, types of comorbid diseases, and patient outcomes (survivor or non-survivor). The exclusion criteria were elderly COVID-19 patients with incomplete Electronic Medical Records (EMR). This study found 122 elderly patients with COVID-19 with a mortality rate of 30.33%. The result showed that NLR on admission significantly increased significantly in the non-survivor group compared to the survivor group. Multivariate Cox regression analysis presented severity (RR: 5.181; CI 1.662-16.154; p=0.005), comorbid diabetes mellitus (RR: 2.829; CI: 1.115-7.178), NLR > 6.04 (RR: 6.356; CI: 2.428-16.639) and other comorbid, namely thyroid, autoimmune, cancer, and anemia (RR: 15.836; CI: 1.841-136.234; p=0.012) as factors of mortality in hospitalized elderly patients.
Antenatal RHD screening to guide antenatal anti-D immunoprophylaxis in non-immunized D– pregnant women
Authors: Clausen Frederik B. 
Published: May 2024

Abstract
In pregnancy, D– pregnant women may be at risk of becoming immunized against D when carrying a D+ fetus, which may eventually lead to hemolytic disease of the fetus and newborn. Administrating antenatal and postnatal anti-D immunoglobulin prophylaxis decreases the risk of immunization substantially. Noninvasive fetal RHD genotyping, based on testing cell-free DNA extracted from maternal plasma, offers a reliable tool to predict the fetal RhD phenotype during pregnancy. Used as a screening program, antenatal RHD screening can guide the administration of antenatal prophylaxis in non-immunized D– pregnant women so that unnecessary prophylaxis is avoided in those women who carry a D– fetus. In Europe, antenatal RHD screening programs have been running since 2009, demonstrating high test accuracies and program feasibility. In this review, an overview is provided of current state-of-the-art antenatal RHD screening, which includes discussions on the rationale for its implementation, methodology, detection strategies, and test performance. The performance of antenatal RHD screening in a routine setting is characterized by high accuracy, with a high diagnostic sensitivity of ≥99.9 percent. The result of using antenatal RHD screening is that 97–99 percent of the women who carry a D– fetus avoid unnecessary prophylaxis. As such, this activity contributes to avoiding unnecessary treatment and saves valuable anti-D immunoglobulin, which has a shortage worldwide. The main challenges for a reliable noninvasive fetal RHD genotyping assay are low cell-free DNA levels, the genetics of the Rh blood group system, and choosing an appropriate detection strategy for an admixed population. In many parts of the world, however, the main challenge is to improve the basic care for D– pregnant women.
An update to Kidd blood group system
Authors: Hamilton Janis R. 
Published: May 2024

Abstract
Since publication of the original Immunohematology review of the Kidd blood group system in 2015 (Hamilton JR. Kidd blood group system: a review. Immunohematology 2015;31:29–34), knowledge has mushroomed pertaining to gene structure, alleles causing variant and null phenotypes, clinical significance in renal transplant and hemolytic disease of the fetus and newborn, and physiologic functions of urea transporters in non-renal tissues. This review will detail much of this new information.

The purpose of the study. Multimodal study of the state of the brachiocephalic arteries, with assessment of blood flow in the extra- and intracranial portions of the carotid arteries and brain perfusion, as well as the structure of the brain in patients with different types of elongation of the carotid arteries (ECA).Material and methods. The data of examinations of 79 patients (45 men (57.0%, average age – 61.0 ± 10.1 years) and 34 women (43.0%, 65.3 ± 13.6 years), average age 62.8 ± 11.8 years) during the year after ischemic stroke in posterior circulation were analyzed. ECA was verified by multispiral computed tomographic angiography (msCTA) in 44 patients (55.7% of the total number of cases), the control group was selected by gender and age with “case-control” elements and consisted of 35 (44.3%) patients without a mustache. All underwent msCTA of the thoracic aorta and BCA and CT perfusion examination, magnetic resonance imaging of the brain, duplex scanning of BCA and transcranial duplex scanning, transthoracic echocardiography, transcranial Doppler monitoring with microembolodetection.Results. We have registered intergroup differences, which can be divided into structural and functional. The former include: higher aortic arch location in patients with DCA: ThII – 6.3% vs. 0%, ThIII – 43% vs. 0%; ThIV – 28.1% vs. 62.9%* and ThV 21.9% vs. 37.1% (p < 0.0005); lower values of cervical spine height (114.70 ± 11.03 mm, vs. 120.46 ± 9.75 mm, p = 0.022), greater absolute length of the ICA (on the right – 101.32 ± 14.59 mm vs. 85.06 ± 12.07 mm, p < 0.0005; on the left – 100.00 ± 14.03 mm vs. 84.66 ± 12.63 mm, p < 0.0005). The presence of ECA was associated (p < 0.05) with a higher frequency of vertebral artery elongation. The severity of small vessel disease during MRI in individuals with ECA was slightly higher (not at the trend level, p = 0.076). Functional differences consisted in the registration of lower (p = 0.019) values of the end diastolic velocity in M1 of the middle cerebral arteries. The values of some perfusion indices in the blood supply of elongation arteries were lower than in persons without ECA. There were no cases of registration of microembolic signals in the ECA patients examined by us.Conclusion. In the individuals with ECA we examined, a complex of anatomical and hemodynamic features was determined, which, both individually and collectively, cannot lead to a decrease in the level of blood flow or be a source of arterio-arterial embolism in the carotid system, regardless of the configuration of the ICA.
A malignancy phantom: a rare clinical case report of metastatic renal cell carcinoma with no evidence of a primary lesion presenting as cerebellar ataxia
Authors: Farraj Husam , Abushalha Kamelah , Bader Husam , Peabody Mitchel F. , Kroker-Bode Claudia 
Published: May 2024

Background:
Anti-Ma2 antibody-associated paraneoplastic syndrome (PNS) usually presents as limbic encephalitis in the context of testicular tumors. We report a rare case of anti-Ma2 positive PNS with deviation from the classic scenario, thus expanding the phenotype of anti-ma2 associated PNS.

Case Presentation:
This is a 53-year-old male who presented with dizziness and visual changes and was later diagnosed with anti-Ma2 antibody-positive cerebellar ataxia. Further workup revealed retroperitoneal lymphadenopathy which, using biopsy, was identified as metastatic clear cell renal cell carcinoma. However, imaging did not reveal a primary renal lesion.

Conclusion:
Physicians should be aware of non-classic presentations of PNSs, especially given that they commonly precede and point towards an underlying, many times undiagnosed, malignancy.
Uncommon cystic presentation of a common cervical mass
Authors: El-Haddad Joya , Tassart Marc 
Published: May 2024

Background:
Parathyroid cysts (PCs) are rare, constituting less than 0.5% of parathyroid lesions. PCs are often asymptomatic or present with non-specific symptoms, posing challenges for accurate diagnosis.

Case Presentation:
We report a case of a 22-year-old female presenting a painless, growing left-sided neck mass. Imaging, including contrast-enhanced neck computed tomography, magnetic resonance imaging, and high-resolution ultrasound (US), revealed a purely cystic lesion in the anterior upper mediastinum. Subsequent US-guided fine needle aspiration cytology (FNAC) confirmed the cystic nature. In situ parathyroid hormone (PTH) levels were elevated, leading to the diagnosis of a non-functioning PC. Surgical intervention was avoided, and symptomatic relief was achieved through US-guided cyst aspiration.

Conclusion:
This case emphasizes the rarity of non-functioning PCs and underscores the importance of a comprehensive diagnostic approach, including imaging studies and FNAC with in situ dosage of PTH levels.
Actuator Surface Modeling of Rotors at the Ship–Helicopter Dynamic Interface
Authors: Linton Daniel , Thornber Ben 
Published: May 2024

The aerodynamics of the ship–helicopter dynamic interface play an important role in determining ship–helicopter operating limits. A review of prior studies, in conjunction with experimental work, indicates that a time-accurate rotor model and a physics-based turbulence-resolving flow solver with two-way coupling between these components are required to accurately predict rotor–airwake and rotor–rotor interactions. Here, a recently developed actuator surface model is validated against two further multirotor cases and employed for two large-scale ship–helicopter dynamic interfaces with up to three concurrent rotorcraft and five rotors. Simulations of the Sikorsky X2 rotor with significant rotor–rotor interaction match resolved unsteady rotor loading well using 1.2% of the computational effort of resolved blade calculations. Computations of the outwash from a Boeing CH-47D in hover gave results within experimental error bars for most azimuths, where discrepancies may be attributed to the estimated trim and division of rotor loading. Simulations of the dynamic interface between the Simple Frigate Shape 1 and a hovering UH-60a were presented for three wind-over-deck angles and three positions for 40 knots of wind speed. The computed thrust and root mean square thrust coefficients in the closed-loop pilot control band are presented and demonstrated to have an to have an expected dependence on immersion in the ship airwake. Finally, a large-scale dynamic interface computation was performed with two CH-47Ds and one UH-60a operating concurrently over the deck of the landing helicopter assault ship at 40 knots of wind speed and 0° and 30° angle. Results highlighted the importance of understanding rotor-wake/airwake interactions dependent on rotorcraft type and position and wind-over-deck. The computation provided unsteady thrust and torque for each of the five rotors from 60 s of data using just 11,424 central processing unit hours on a grid of [Formula: see text] points. These simulations show that hybrid Navier–Stokes simulations employing actuator line or surface methods are capable of providing high-fidelity, time-accurate predictions of rotor loads at the ship–helicopter dynamic interface at substantially lower cost.

Published: May 2024

In order to fulfill the demand for energy and food security, an active heating of a controlled environment greenhouse integrated semitransparent photovoltaic thermal (GiSPVT) system with N-semitransparent photovoltaic thermal (SPVT) air collector for cold climatic conditions has been analyzed in this paper. The proposed SPVT air collectors are connected in series and integrated with GiSPVT. It is used to generate thermal as well as electrical energy to meet the daily requirements of users. Based on the energy balance equation which is a function of design and climatic parameters, an analytical expression for various variable parameters namely plant, room air, and solar cell temperatures have been derived. Numerical computation has been made in Matlab for computing the thermal, electrical, and overall exergy of the proposed system. Based on numerical computation, the following observations have been made:
(i)
From a thermal point of view, the packing factor (0.5, 0.8) of the semitransparent PV module plays an important role and it must be optimized for maximum thermal heating.

(ii)
The selection of a number of collector N is an important parameter to generate electrical energy as well as thermal heating of GiSPVT room air in an optimum way.
Quadrilles of the Southern Part of the Chelyabinsk Region: Type, Structure, Variants
Authors: Мартынова Н.Э. 
Published: May 2024

Статья посвящена структурному и композиционному анализу кадрилей русскоязычных сел южной части Челябинской области, типологическое объединение которых основывается на конструктивном соотношении с «французской кадрилью». Появление и распространение последней отвечало тенденциям времени, а принципиальная незавершенность организации композиции создавала условия ассимиляции в уже сложившейся традиции русской хореографии. Модная форма задавала жанровые границы и одновременно возможности развития, что объясняет столь широкое распространение кадрили в крестьянской среде. Построение инвариантной модели рассматриваемых кадрилей дает основание увидеть целостное содержание композиционного типа: структуру, ее организацию — и позволяет выделить структурные единицы (формулы), заложенные в формировании коротких танцевальных отрывков — фигур. Последнее определяет выбор соответствующих выразительных средств и дает возможность соотносить разницу схем фигур вариантных примеров в контексте соответствующего замысла. Модель инварианта также помогает более четко увидеть локальную специфику вариантных кадрилей, разрабатывающихся в рамках танцевальных требований обозначенной территории. Автор приходит к выводу, что форма кадрили в две пары южной части Челябинской области отличается лаконичностью в организации системы рисунков.
This article analyzes the structure and composition of the quadrilles of Russian-speaking villages in the southern part of the Chelyabinsk region. They are typologically related to the “French Quadrille”; their appearance and distribution in Russia corresponded to the trends of the time, and the fundamental incompleteness of their composition created conditions for the assimilation of elements from the already established tradition of Russian choreography. The fashionable form set genre boundaries and at the same time offered opportunities for development, which explains the wide distribution of the quadrille in the peasant environment. The article presents an invariant model for the quadrilles that makes it possible to see the integral content of their composition and the elements of their structure and organization. This also allows us to identify structural units (formulas) embedded in the formation of short dance fragments or figures. These structural units determine the choice of expressive means and makes it possible to correlate differences among the variant figural schemes, helping us to see the local specificity of variant quadrilles within the dance traditions of the given territory. This analysis leads to the conclusion that the two-pair square dance form from the southern part of the Chelyabinsk region features laconism in its organization of patterns. The article also comments on the everyday life of these quadrilles.
Sociocultural and Emotional-Psychological Features of Komsomol and Pioneer Songs of the 1920–1980s
Authors: Поздеев В.А. 
Published: May 2024

В статье рассматриваются особенности комсомольских и пионерских песен 1920–1980-х гг. Часть исследования посвящена социально-политическим и культурным предпосылкам создания «новых» революционных песен и песенников. Песенники публиковались в столицах и в провинции, по составу часто они перекликались. Выявлена структура и состав песенников различных лет. Специальное внимание уделено элементам эмоциональной направленности песен, а также языковым средствам, используемым при выражении чувств автора/исполнителя. Определяется эмотивная лексика и другие элементы текста, которые воздействуют на эмоциональную сферу слушающего. Показано, как трансформация социально-исторических и эмоционально-психологических установок в советской комсомольской и пионерской песне 1920– 1980­х гг. отражает «волнообразный» процесс идеологических изменений в массовой музыкально-песенной культуре.
This study examines Komsomol and Pioneer songs of the 1920s–1980s. Part of the study is devoted to the socio-political and cultural prerequisites for the creation of revolutionary songs and songbooks. Songbooks were created both in the capitals and provinces; their content often overlapped. The structure and composition of songbooks of various years is also considered. The article focuses in particular on the emotional elements of the songs as well as the linguistic means used to express the performer’s feelings, as emotive vocabulary and other elements in the text affect the listener’s emotional responses. It suggests that the transformation of socio-historical and emotional-psychological attitudes in Soviet Komsomol and Pioneer songs of the 1920s–1980s reflects a “wave-like” process of ideological change in mass music and song culture.
“Within the First Few Minutes God Created Universities”: Collective Memory and Personal Narrative
Authors: Воробьев В.А. 
Published: May 2024

В статье рассматриваются различные контексты бытования студенческой песни «В первые минуты бог создал институты…», возникшей в ХХ в., но аккумулирующей различные слои песенной культуры русского студенчества XIX–ХХ вв. Прослеживаются линии бытования студенческой песни через коллективную память, сохраняющую устойчивые содержательные элементы студенческой песни XIX в. — пьянство студентов и топику, связанную с идентичностью сообщества. Учитываются также личные нарративы, которые влияют на бытование и вариативность текста, превращая песню если не в полноценную биографию исполнителя, то во фрагменты биографии с основными этапами студенческой жизни. Специально анализируется политическая топика, обретенная студенческой песней на рубеже веков и продолжающая включаться в тексты студентов во второй половине ХХ в. Часть исследования посвящена рассмотрению студенческой песни как части традиции русской parodia sacra, а также ритуальным структурам и бюрократическим элементам, позволяющим отечественной сакральной пародии жить вплоть до эпохи постфольклора и традиций городской песни ХХ в. Специально рассматриваются механизмы, влияющие на вариативность песни «В первые минуты бог создал институты…», а также широкий контекст происхождения песни — от военной песни на стихи Константина Симонова через авторскую переработку Владлена Бахнова до многообразия вариантов во второй половине ХХ в.
This article considers various contexts of the student song “Within the First Few Minutes God Created Universities,” which emerged in the twentieth century, but which reflects various layers of Russian student song culture of the nineteenth and twentieth centuries. The song preserves elements of nineteenth-century student songs that may be said to belong to the collective memory. This includes the theme of student drunkenness and topics connected with the identity of the community. The performer’s personal narrative is also present. This helps account for the existence and variability of the text, turning the song, if not into a full-fledged biography, at least into fragments of biography, that mention the main stages of student life. The article also analyzes the political topics that began to appear in student songs at the turn of the century and that continued to be included in student texts of the second half of the twentieth century. The study also examines student song as a part of the tradition of Russian parodia sacra, considering the ritual structures and bureaucratic elements that allow domestic sacred parody to survive in the post-folklore era and in the context of twentieth-century urban song traditions. Mechanisms influencing variations of the song “Within the First Few Minutes God Created Universities” are also examined, as well as the song’s development from a war song based on Konstantin Simonov’s poems to author Vladlen Bakhnov’s reworking of the song, to later variants.
The Dispute About St. George the Victorious in Poetic Texts About the Miraculous Events on Nikolskaya Mountain
Authors: Липатова А.П. 
Published: May 2024

Статья посвящена анализу стихотворных произведений наивного поэта Валерия Александровича Еремина, проживающего в пгт Сурском Сурского района Ульяновской области. На территории поселка расположена Никольская гора — крупный сакральный центр, почитаемый жителями Ульяновской области и соседних регионов. Согласно устной и письменной традиции, Никольская гора стала почитаться как святая после того, как на ней явился Николай Чудотворец и отпугнул врагов, угрожающих селению. У Валерия Александровича есть своя версия события, отличная от официальной. Ее он транслирует в стихотворных произведениях. Информационный фонд сакрального места с богатой историей состоит из нескольких слоев: письменные тексты второй половины XIX — начала XX в., современные устные и письменные рассказы. Вариации чудесного события, приведшего к сакрализации горы в Промзине (ныне — пгт Сурское), знакомы самодеятельному поэту, но ни одна из них не становится для него ведущей. «Специфическая амбициозность» (М. Лурье) творчества наивного поэта приводит к «пересборке» концепта «малая родина». Спор с версиями чудесного события, реализуемыми в современных нарративах и рассказах конца XIX — начала XX в., позволяет поэту вписать историю малой родины в мировую историю.
This article analyzes poetic works by the naive poet Valery Alexandrovich Eremin, who lives in Sursky (formerly Promzino), Sursky district, Ulyanovsk region. That is where Nikolskaya Mountain, a large sacred center revered by residents of the Ulyanovsk and neighboring regions, is located. According to texts from the second half of the XIX – early XX century as well as modern oral and written accounts, Nikolskaya Mountain became revered as holy after Nicholas the Wonderworker appeared on it and scared away enemies who were threatening the village. Since the late nineteenth century, however, some have cast doubt on the story’s veracity. Eremin has his own poetic version of the event, different from existing accounts, with which he is familiar, although none of them is authoritative for him. According to Mikhail Lur’e, the special nature of a naive poet’s patriotism leads to a “reconstruction” of the concept of “small homeland” (land of one’s birth), and instead of seeking artistic perfection, the naive author “sees his [work’s] merit in ‘informing’ other people — fellow villagers, descendants, potential readers.” Debate over the nature of the miraculous event has allowed the poet to create his own history, inscribing his small homeland into world history.
