Complications after volar plate synthesis for distal radius fractures
Authors: Pacchiarini Luca , Massimo Oldrini Lorenzo , Feltri Pietro , Lucchina Stefano , Filardo Giuseppe , Candrian Christian
Published: June 2024

Purpose

Distal radius fractures (DRFs) represent up to 18% of all fractures in the elderly population, yet studies on the rate of complications following surgery are lacking in the literature. This systematic review aimed to quantify the rate of complications and reinterventions in patients treated with volar plate for distal radius fractures, and analyze if there was any predisposing factor.

Methods

A comprehensive literature search was performed on three databases up to January 2023, following PRISMA guidelines. Studies describing volar plate complications and hardware removal were included. A systematic review was performed on complications and rate of reintervention. Assessment of risk of bias and quality of evidence was performed with the ‘Down and Black’s Checklist for measuring quality’.

Results

About112 studies including 17 288 patients were included. The number of complications was 2434 in 2335 patients; the most frequent was carpal tunnel syndrome (CTS), representing 14.3% of all complications. About 104 studies reported the number of reinterventions, being 1880 with a reintervention rate of 8.5%. About 84 studies reported the reason of reintervention; the most common were patient’s will (3.0%), pain (1.1%), CTS (1.2%), and device failure (1.1%).

Conclusion

The complication rate after DRFs is 13.5%, with the main complication being CTS (14.3%), followed by pain and tendinopathy. The reintervention rate is 8.5%, mainly due to the patient’s willingness, and all these patients had plate removal. Correct positioning of the plate and correct information to the patient before surgery can reduce the number of hardware removal, thereby reducing costs and the risk of complications associated with VLP for distal radius fractures.

Luego de estudiar diferentes diseños instruccionales y de analizar la problemática de la institución respecto a la falta de metodología instruccional para la creación de cursos virtuales para el apoyo a cursos presenciales en las diferentes carreras de la Universidad Experimental Politécnica de la Fuerza Armada (Unefa), núcleo Mérida, se ha desarrollado una metodología instruccional para esta institución, con el fin de apoyar a los docentes en el desarrollo de los cursos virtuales y en el uso de la plataforma Moodle. Esta investigación es un proyecto factible, de tipo descriptiva y de campo. Se realizó una encuesta a los docentes con el fin de establecer cómo desarrollar y crear la metodología instruccional, la cual es el producto de esta investigación. Como resultado se presenta la metodología instruccional Prandineu, con la cual se realizó una prueba piloto en la plataforma Moodle. Se puede concluir que en porcentajes significativos los docentes planifican casi siempre las clases virtuales que deben impartir a sus alumnos, registrando diariamente las actividades previstas. Así mismo, rara vez organizan las estrategias académicas considerando la opinión de los estudiantes. La dirección y evaluación de los procesos técnico-administrativos en la Gerencia de Aulas Virtuales se logra en porcentajes significativos al guiar y orientar a los estudiantes, estableciendo actividades para realizar a distancia, con la aplicación de técnicas de estudio que dan lugar a un aprendizaje apropiado. Sin embargo, rara vez se verifica el logro de estos objetivos por medio de evaluaciones.

Introduction. From the perspective of scientific publishing, the Heredia Declaration proposes a series of considerations for the responsible use of Artificial Intelligence (AI) in the research processes that lead to scientific publication. AI is recognized as a tool whose use must be evident and transparent for a clear, traceable, and reproducible communication of knowledge. Attention is drawn to the challenges posed by the inclusion of AI into scientific publishing regarding the diversity of options, avoiding the spread of bias and misinformation, and respect for intellectual property. Principles. They are organized into four groups: general, for authorship, peer review, and editing roles. These principles highlight the importance of using AI as a tool, its results must be filtered by human beings and from an ethical and responsible perspective, transparently reporting which model was used, what was consulted, and when the consultation was made. Final reflection. It shows that it is a constantly evolving scenario whose goal must be human well-being and quality of life.

Purpose

To identify the most predictive ultrasound parameters for the assessment of male infertility by a multiparametric study.

Materials and Methods

A total of 64 males were recruited in the study group and 14 men in the control group. At first, grey-scale and color and Power Doppler ultrasonographic imaging was used to analyze testicular morphological characteristics and detect intratesticular abnormalities. Various ultrasound parameters of B-mode US and strain-elastography were related to total sperm count (TSC).

Results

The prevalence of varicocele was not significant (P = 0.33), though presented a 2.53-fold odds ratio The strain ratios of both testes, the volume of the left testis and the size of the left appendix were most associated with the results of semen analysis according to a Variable Importance in the Projection (VIP) score of >1. The first latent variable from the PLS analysis explained a significant amount of variance in TSC, concentration, and motility parameters (P < 0.0002) and showed that bilateral strain ratio, the size of the testis, and the volume of left appendix were the most significant US predictors of the pathological semen and sperm cell features.

Conclusions

Our results showed that B-mode US with strain elastography is among more sensitive US approaches in evaluating male fertility.

Published: June 2024

Alginic acid is an intermediate product in the alginate extraction process. In this study, alginic acid was generated from three separate sections of the thallus. The study aimed to define the influence of alkali solvents for pretreatment and the thallus parts from S. polycystum to produce alginate. Thus, this study identifies the proper utilization of seaweed as a source of alginate. The extraction procedure to obtain alginic acid was performed using Na2CO3 at a 2% concentration. The pretreatment improved the quality before extraction by soaking in KOH as a solvent. The statistical analysis was used to define significant differences in the pretreatment and thallus parts of the S. polycystum using ANOVA and the Tukey test as the post hoc. Alkali pretreatment and thallus sections substantially influence alginic acid yield, viscosity, and gel strength. Yield, ash content, moisture, pH, viscosity, whiteness degree, and gel strength of the best alginic acid chosen (pretreatment with KOH 0.90% from the basal section) were around 21.51 %, 10.34 %, 7.04 %, 2.54, 53.37 cP, 57.91 %, and 58.80 g/cm2, respectively. Except for the ash content parameter, the qualities of the alginic acid generated satisfied the standard. In conclusion, it is a better understanding of the alginate production from different thallus parts, making utilization more effective.

The potential of Rhizophora mucronata mangrove fruits as antioxidants is noteworthy, with promising prospects as nutraceuticals, particularly in their role as immunomodulators for T lymphocyte cells. R. mucronata fruits have been utilized by household industries in Indonesia as a coffee-like drink (artificial coffee). This study aims to determine the ability of mangrove fruit artificial coffee R. mucronata to stimulate T lymphocyte cells and renal histopathology conditions in LPS-induced mice animal models. This study also characterizes proximate characteristics, antioxidant capacity, and Gas Chromatography-Mass Spectrometry (GC-MS) screening of mangrove fruit artificial coffee compounds. The stages of this research included the process of mangrove fruit artificial coffee; analysis of proximate and caffeine; compounds screening (GC-MS) and toxicity prediction (Pro-Tox II); antioxidant capacity (DPPH); T lymphocyte cell expression (flow cytometry); and renal histopathological evaluation. The results showed moisture content (5.22±0.20%); ash (5.17±0.27%); protein (13.74±0.24%); fat (11.63±0.32%); carbohydrate (64.23±0.15%), caffeine (1.09±0.04%). GC-MS analysis showed that the compounds contained in artificial coffee were derivatives of fatty aldehyde, fatty acid, and cycloalkanes compound classes. Predicted toxicity of artificial coffee LD50 5000 mg/kg. Antioxidant capacity is classified as moderate (IC50 119.41±0.99µg/mL). Mangrove fruit artificial coffee can increase the relative number of CD4+CD62L+ by 14.68-29.48% and CD8+CD62L+ T lymphocyte cells by 12.60-30.33%. Artificial coffee can also increase the number of healthy cells and reduce the cells that undergo necrosis in the renal of LPS-induced mice. This study concluded that mangrove fruit artificial coffee R. mucronata positively affects T lymphocyte activation and mice renal cells’ protection from necrosis due to LPS induction.

Published: June 2024

Seaweed contains various bioactive compounds rich in pharmacological potentials, such as antioxidants and anti-arthritic. This study aims to determine the antioxidant and anti-arthritic activities of the methanolic extract of Halimeda tuna. Halimeda tuna samples were extracted using the maceration method and methanol. The methanol extract was tested for antioxidant (2,2-diphenyl-1-picrylhydrazyl (DPPH), ferric reducing antioxidant power (FRAP)) and anti-arthritic activity using denatured bovine serum albumin (BSA). The methanol extract was also subjected to phytochemical and Gas Chromatography-Mass Spectrometry (GC-MS) analysis. Research results revealed that the extract yield was 0.50 ± 0.06%. Phytochemical analysis showed that H. tuna methanolic extract contained flavonoids, steroids, and alkaloids. GC-MS analysis showed that H. tuna methanolic extract contained steroids, fatty alcohols, and fatty acids. The antioxidant activity tests revealed an IC50 value of 299.98 ± 121.15 ppm and a FRAP value of 200.02 ± 8.50 M/g, categorized as a weak antioxidant. Anti-arthritic activity of H. tuna methanolic extract showed an IC50 value of 877.29 ± 209.84 ppm. The anti-arthritic activity of H. tuna methanolic extract was lower than sodium diclofenac as a standard drug. The extract of H. tuna has antioxidant and anti-arthritic activities; hence, further exploration is needed as an alternative potential in the pharmacological field.

Energy transfer and stress wave propagation during SPT through energy measurement and PIV
Authors: Wong Eugene Kwan Lok , Sze Eric Hon Yue , Chung Philip Wai Keung , Wong Louis Ngai Yuen
Published: June 2024

The blow counts in standard penetration tests (SPTs) require suitable corrections to account for energy losses. Over 4000 energy measurements collected from four test sites across Hong Kong were collected and analysed in this study. On average, for all instrumented hammer blows, approximately 62% of the theoretical hammer potential energy was transferred to the drill rod assembly. Using high-speed camera imagery and particle image velocimetry (PIV), the detailed mechanism of stress wave propagation was visualised and assessed. This revealed new details and allowed nuances in the results of routine energy measurements to be interpreted in new light. The results showed that the initial compressive wave is reflected as a tensile wave for low end-restraint at the SPT sampler and as a second compressive wave for high end-restraint. Commonly observed discrepancies between theoretical and measured speeds of wave propagation were explored. Energy loss arises from friction during free-fall of the hammer, at the anvil and from other sources such as the horizontal motion of the hammer–anvil system. The proportion of each major source of energy loss was quantified.
Not so peculiar after all: On the normal position of arguments of German experiencer-object verbs
Authors: Masloch Simon , Poppek Johanna Marie , Kiss Tibor
Published: June 2024

The present paper argues that seemingly erratic linearisation patterns of experiencer-object verbs in German can be accounted for by considering well-known linearisation constraints. The analysis is based on two Two-Alternative Forced-Choice experiments: The first study tests experiencer-object verbs with inanimate subjects, the second one tests experiencer-object verbs with animate subjects. If the subject is inanimate, experiencer-object verbs selecting a dative object (e.g., behagen ‘to please’) prefer an object-before-subject linearisation while the ones selecting an accusative object (e.g., bezaubern ‘to charm’) lean towards subject before object. With animate subjects, accusative-object experiencer-object verbs prefer subject before object, while there is no clear preference for dative-object experiencer-object verbs. An explorative investigation reveals verb-specific differences that call into question the case-based classes. We argue that linearisation preferences of experiencer-object verbs in German should be analysed by coupling free base generation with violable linearisation constraints. We provide an analysis along these lines, which is based on a semantic distinction and does not require case-based constraints.

Published: June 2024

The thermal conductivity of natural monoliths of calcite, dolomite marble, and limestone from various deposits was measured using the absolute stationary method of longitudinal heat flow in the temperature range of 50–300 K and the dynamic method in the range of 323–573 K. A majority of calcite marbles were inferior in thermal conductivity to dolomite marbles. At room temperature, the thermal conductivity coefficients of all studied samples were lower k = 5 W/(m K).
The obtained data were compared with the literature data. The diversity of experimental data from different authors on the thermal conductivity of carbonates is associated with qualitative differences in the samples studied

Published: June 2024

One of the most fragile places on earth is the coastal zone. There are several different ecosystems in this area. In this area, erosion and accretion are typical natural occurrences. These changes could also threaten the coastal ecology. Uneven coastal changes can result from natural processes such rainfall, cyclones, floods, tectonic shifts and longshore drift. Similar to this, anthropogenic influences like mining, unscientific land use, urbanisation, etc., contribute to coastal processes and bring much more significant alterations in the coastal region. Therefore, identifying such a location is crucial. Advanced approaches for studying shoreline change have been made possible by geospatial technology. The enormous effort to obtain an accurate result over a greater area has become easier as a result. In order to examine the changes in the Cuddalore shoreline during the years 2002, 2007, 2013, 2017, and 2022, Landsat satellite imageries with 30 m spatial resolution were used. The Digital Shoreline Analysis System (DSAS) tool for analysing shoreline change has been integrated to Geographic Information System (GIS) software. DSAS was used to construct the baseline transects for the shoreline change measurement. Using the MATLAB feature runtime function for ArcGIS, the rate of shoreline change was computed. Based on the DSAS output, the area of high erosion, low erosion, stable, and low accretion, high accretion zones were assessed on the coastline. The results reveal that 15.38% of the shoreline, around 6.8 km is under high erosion. 12.2% of the shoreline, which is around 5.4 km, is under low erosion. 32% of the shoreline, around 14.5 km, is a stable region. 26.9% of shorelines, around 11.9 km, is low accretion, and 12.6% of shorelines, around 5.6 km, is high accretion. The coastal villages, namely, Gundupallavadi, Cuddalore, Thandavarayancholanga pettai, Ariyakoshti and parangipettai have a high erosion with a maximum rate of change between -3 to -14 m/y. The coastal villages Patchayankuppam, Cuddalore, Tiruchchepuram, Kayalpattu, Kothattai, Ariyakoshti, Parangipettai have high accretion with a maximum rate of change between 3 to 10 m/y.

Published: June 2024

This research area is located along the Hazara-Kashmir Syntaxis in the sub-Himalaya. The Hazara-Kashmir Syntaxis runs through numerous areas within Mirpur district. One of the key characteristics of the Hazara-Kashmir Syntaxis is its antiformality. The project area is bounded to the east by the Riasi fault and to the west by the Jhelum fault, while to the south it is bounded by Salt Range Thrust. Research is being conducted in the areas of Narmah, Sahan, Pirgali, Kas Guma, Mohra Jangu, and Kalri. Fold-and-thrust belts are present in the sub-Himalayan region ofPakistan. Essentially, there are two major folds: the Sahan syncline and the Gaiyan anticline. The Sahan syncline is characterized by an open fold and a southwest orientation. In contrast, open-to-close folds in Gaiyan anticlines are oriented to the southwest. The area is characterized by five major faults: the Narmah fault, the Dhok Poran fault, the Dubal fault, the Pirgali fault, and the Jabi fault. Folds and faults in the project area are the product of NE-SW or NW-SE compaction of the Himalaya. In the research project area sedimentary rocks of Early Miocene- Recent age are located. The rocks which are exposed in the study area includes: the Early-Middle Miocene Kamlial Formation, Middle-Late Miocene Chinji Formation, Late-Miocene Nagri Formation, Late-Miocene Dhok Pathan Formation, Pliocene Soan Formation, and Quaternary Alluvium deposits. Sedimentary structures in the area consist primarily of crossed bedding and rip-ups. These structures define the facing of stratigraphic units.
Northern Limit of the Concealed Bundelkhand Craton: A Synthesis of New Magnetotelluric Results from the Ganga Basin

Published: June 2024

The Bundelkhand craton is a relatively small craton of the Indian shield in terms of its exposed surface area. It continues beneath the sediments of the Ganga Basin in NE-to-NNE direction as the Faizabad Ridge. However, its northern extent into the Ganga Basin is not known and the northern margin of the exposed craton is generally taken as the northern limit of the craton. Here, we present a synthesis of new magnetotelluric (MT) results from the Ganga Basin to demarcate the northern limit of the Bundelkhand craton. Broadband MT data were acquired at 148 sites along the four profiles and the MT impedance tensors of 132 sites were used for two-dimensional inversion along these profiles. The top 15 km sections of the geoelectric models along these profiles were used to prepare a conductance map to extract the northern limit of the electrically resistive craton. The results reveal that the northern boundary of the craton lies much to the north of the presently known northern limit. It also follows the basement depth contours of 2 km and 3 km obtained from the aeromagnetic data. Thus, a significant part of the craton is also buried in the Ganga Basin north of its present limit. The areal extent of this new buried block is about 0.82 times the area of the exposed Bundelkhand craton. Together with the Faizabad Ridge, the Bundelkhand craton covers an area of about 1,03,000 sq.km, 72% of which is concealed under the sediments of the Ganga Basin. The results also indicate westward subsurface continuation of at least a part of the craton towards the Great Boundary Fault.

Published: June 2024

The primary goal of this study is to determine soil erosion risk susceptibility and to suggest the most appropriate techniques for soil erosion susceptibility for Gumani river basin. This research examined the point-specific values of several components derived from randomization. The susceptibility of the projected frameworks, namely the Artificial Neural Network and Support Vector Machine, was investigated with the help of the most significant causative variables and the corresponding field records. The area underneath the Receiver Operating Characteristics curve shows accuracy for ANN and SVM accordingly. For assessing susceptibility, the ANN (AUC = 0.932) and SVM (AUC = 0.915) were used for training points, whereas ANN (AUC = 0.906) and SVM (AUC = 0.882) were for validation points. The ANN model is very efficient in simulating the erosional and non-erosional regions more accurately than SVM. The outcome of ANN predicted that 19.14% area is very high, extended in the entire western parts and some parts of the southern part, 14.96% is high, extended in the entire western part, 16.01% is moderate, extended in the western and eastern parts, 18.54% low, and 31.35% very low extended in the middle and eastern parts, susceptible for soil erosion whereas the outcome of SVM predicted that 15.45% area is very high, 18.82% high, 22.05% moderate, 22.94% low, 20.74% very low, susceptible for soil erosion. The land degradation phase is not a unidirectional process. Therefore, multidimensional effects from conditioning factors must be calculated accurately by considering the maximum possible variables and choosing optimum models for particular areas. These attempts will help policymakers implement proper methods to check soil erosion in the Gumani river basin.

Published: June 2024

The area around Renukoot town shows the exposure of garnetstaurolite- mica schist belonging to the Chhotanagpur Granite Gneiss Complex (CGGC). The characteristic mineral assemblage present in the rock are garnet–biotite–staurolite–quartz along with minor opaque minerals like rutile, ilmenite and hematite. For the constituent minerals, the calculated XMg value decreases in the order: chlorite>biotite>staurolite>garnet. The metamorphic conditions of the garnet-staurolite-mica schist were determined using the winTWQ and Perple_X programmes, and the peak pressure-temperature conditions for the rock are estimated to be 5.3 kbar and 570°C. The metamorphic episode in the CGGC during Mesoproterozoic time may be attributed to the global level Columbian Super-continental accretionary orogeny.
Syntectonic Shear-induced Emplacement of Crystallizing Granite Magmas Evident from Magmatic Shear Sense, Mafic Schlierens, and Microgranular Enclaves in the Mesoproterozoic A-type Kanigiri Pluton, Nellore Schist Belt, Southeast India
Authors: Narshimha Ch. , Kumar Santosh
Published: June 2024

The observations on field-based mesoscale magmatic structures suggest that the A-type Kanigiri granite (KG) pluton, Nellore Schist Belt (NSB) has undergone a long plutonic history as evidenced by the continuum of deformation from early magmatic to the ductile regime at the waning stage of pluton evolution. The linear alignment of the KG pluton, which lies sub-parallel to the regional Terrane Boundary Shear Zone (TBSZ), and the long-standing deformation regime indicate the genetic link with this shear zone. The formation of mafic schlierens in the KG pluton owes to the mechanical crystal flow-sorting process during the replenishment of KG magma, which is further induced by the injection of crystal-charged microgranular enclave (ME) magmas in the crystallizing felsic magma chamber. The outflown ME magma blobs from the walls of the conduit during the invasion trigger the local turbulence, resulting the swirling of early crystallized mafic crystals of the host KG magma. This kind of swirling in the host KG magma must have been formed at an early stage of crystallization i.e., crystal-poor condition of the KG melts. When the MEs flow out, gravity causes them to interact with the host KG magma and attempt to dissolve into it. This results in schlieren rims formed around the MEs. The magmatic shearing observed in the KG pluton results from an active crystal-mush environment due to accumulated strain caused by the syntectonic movement as evidenced by the magmatic sense of shears. The locally formed slickensides are sub-magmatic origin during the upward pushing of replenishing ME and another pulse of KG magma. The presence, spread and prevalence of magmatic structures like ME magma globules, magma flowage, mafic schlierens, slickensides and shear sense indicators in the KG pluton suggest that the KG pluton underwent dynamic magma emplacement and evolution due to a shear zone, probably the TBSZ, which acted upon KG pluton in a syntectonic environment.
Revisiting the paper ”Simulating dynamical features of escape panic”: What have we learnt since then?
Authors: Haghani Milad , Ronchi Enrico
Published: June 2024

The paper "Simulating dynamical features of escape panic" by Helbing, Farkas, and Vicsek, published over two decades ago in Nature, has left an indelible mark on the field of crowd dynamics.With nearly 3,000 citations to date, according to the Web of Science records, this influential work has significantly shaped the field. This analysis investigates the overall influence of this paper through various indicators, documenting its reach across multiple research areas. The intellectual foundation of the paper is traced, examining the references cited and uncovering some misalignments between certain assertions and the citations meant to support them. The terminological impact is also explored, showing how the paper invigorated the use of terms like "panic" and "herding". Moreover, the alignment of some key assumptions of the paper with empirical evidence that has emerged since its publication is investigated, revealing discrepancies in key assertions about panic behaviour. It is also determined that the numerical observations of the paper have significantly influenced the field by introducing concepts such as the "faster-is-slower" phenomenon, on which empirical research has since produced mixed evidence rather than irrefutable support.While the paper remains a key pillar in crowd dynamics, we advocate for a new course for the field that could facilitate a paradigm shift in conceptualising crowd behavior, particularly one that reconsiders some terminologies and key behavioral concepts adopted in the paper, rather than treating them as proven.
The role of retroelements of the human genome in the development of type 1 diabetes mellitus
Authors: Mustafin Rustam N.
Published: June 2024

Retroelements (retrotransposons and endogenous retroviruses) are a class of mobile genetic elements that move in the genome by inserting their own reverse transcribed transcripts. They serve as drivers of epigenetic regulation; therefore, individual characteristics of the distribution of retroelements in the genome influence the development of multifactorial diseases. Type 1 diabetes mellitus is a multifactorial disease with an immune response against pancreatic β cells. The role of heredity in the development of the disease is estimated at 88%, and the role of allelic variants of various genes is determined. There are also other specific types of diabetes mellitus, which account for more than 2% of cases of diabetes mellitus and are monogenic diseases with an autosomal dominant mode of inheritance due to germline mutations in the MODY genes, including HNF4A, GCK, HNF1A, HNF1B. Most patients with type 1 diabetes have the protein product and ribonucleic acid (RNA) of the insulin inhibitor HERV-W-Env, which is caused by abnormal expression of the human endogenous retrovirus (HERV). An assumption has been made about the role of retroelements in the development of type 1 diabetes mellitus. This is due to their involvement in the phylogenetic formation of the endocrine system, since in evolution retroelements turned out to be sources of regulatory sequences of hormone genes, nuclear hormone receptors and binding sites for them. Type 1 diabetes mellitus is associated with the integration of HERV into the HLA-DQ gene region, with allelic variants and sizes of VNTR variable tandem repeats (part of the SVA retroelements), which regulate the expression of the insulin gene and other hormones. For this reason, it is likely that the development of type 1 diabetes mellitus may be based on individual characteristics of the distribution of HERVs in the human genome and their dynamic changes in ontogenesis. HERVs also play a role in the etiopathogenesis of diabetes mellitus through the activation of an autoimmune response, the triggering factors of which are exogenous viral infections and stress. Thus, retroelements are involved in various mechanisms of the development of type 1 diabetes mellitus, which reflects their global regulatory influence on endocrine regulation.
Cluster approach to identifying the 5-year prognosis of patients with chronic heart failure of ischemic etiology
Authors: Khazova Elena V.
Published: June 2024

BACKGROUND: The phenotypic and pathophysiological heterogeneity of patients with chronic heart failure increases the interest of researchers in grouping according to similar clinical and genetic characteristics based on cluster analysis.
AIM: To identify phenotypic subgroups in a multivariate cohort of patients with chronic heart failure secondary to coronary artery disease using uncontrolled cluster analysis of clinical, instrumental and genetic components.
MATERIAL AND METHODS: 470 patients with chronic heart failure of functional class I–IV, stable course, ischemic etiology of both sexes at the age of 66.4±10.4 years were examined. A clinical study was conducted, genotyping single nucleotide polymorphisms rs10927875 of the ZBTB17 gene, rs247616 of the CETP gene, rs1143634 of the IL-1β gene, rs1800629 of the TNF gene, rs1800795 of the IL-6 gene was carried out, and patient outcomes were assessed for 5 years. Quantitative data were presented as mean and standard deviation or median and interquartile range; categorical — as frequencies and percentages. Categorical intergroup differences were tested using the χ2 test, and quantitative differences were tested using the Student/Mann–Whitney test. Hierarchical clustering was carried out according to 44 demographic, clinical, genetic variables, time to event was analyzed by the Kaplan–Meier method, risk ratio — by Cox regression. Statistical processing was carried out in the R4.3.1 program.
RESULTS: Two clusters of patients with heart failure were identified. Cluster 1 (66%) included older patients of both sexes, predominantly functional class III–IV chronic heart failure, with enlarged heart chambers, reduced left ventricular ejection fraction, higher heart rate, atrial fibrillation and left ventricular hypertrophy. In this cluster, more carriers of the GG genotype of the rs1800795 polymorphism of the IL-6 gene (p 0.001) and the CT genotype of the rs247616 polymorphism of the CETP gene (p=0.014) were identified. Cluster 2 (34%) was represented predominantly by younger women, with a higher metabolic index, a history of myocardial infarction and coronary intervention, smokers, and a larger proportion of the TT genotype of the rs247616 polymorphism of the CETP gene (p=0.029).
CONCLUSION: 2 clusters of patients with chronic heart failure, characterized by a different set of 44 variables that determine the risk of death from all causes, were identified.

Published: June 2024

BACKGROUND: To achieve the number of potential bone marrow donors in Russian registries to a level sufficient for effective selection of recipients in need of transplantation, it is important to find the most effective ways to recruit Russians as potential bone marrow donors.
AIM: To identify areas for improving methods of recruiting potential bone marrow donors in the Russian population.
MATERIAL AND METHODS: An electronic survey was conducted: the questionnaire included 27 questions, the respondents were participants in the register of potential bone marrow donors of the Vasya Perevoshchikov National Register of Bone Marrow Donors Charitable Foundation, expert validation and a preliminary pilot survey were used. The focus was on factors that determine the population’s readiness to donate, preferred methods of donating biomaterial and territorial accessibility of recruitment centers, opportunities and obstacles to recruiting bone marrow donors. 6,314 people took part in the survey. The work used frequency analysis methods and the Pearson χ2 statistical criterion; the data was processed in the SPSS Statistics program.
RESULTS: The most common channels of information about bone marrow donation in the process of involving potential registry participants were mass media (33.6%), social media (18.9%) and the social environment (18.4%). Among the respondents, 30% had experience in human blood donation. The social environment of donors included people who had experience in donating blood: among those surveyed, 48.5% indicated that their relatives served as blood donors; 67.7% noted that their friends were blood donors. For 40% of the registry participants, the method of submitting biospecimens was important. The majority (87%) of respondents indicated that submitting biospecimens at medical centers was the most convenient mechanism for joining the registry.
CONCLUSION: The media serve as an effective channel for informing the population; the role of new social media (Internet resources, social networks) is increasing. A significant factor in involvement in the register is the social environment, including people who have experience in donating blood.
Comparative Legal Analysis of Beauty Clinic Services between Indonesian Law and Islamic Law
Authors: Sari Siska Diana
Published: June 2024

In line with the evolving needs of consumers who strive to improve their facial and physical appearances, beauty clinics frequently introduce new services supported with new technological devices. Some forms of esthetical treatment introduced in the market have risen controversy in terms of their legality. This article aims at  exploring the legality of esthetic treatment provided by beauty clinics from  the perspective of Indonesian law and Islamic law. This normative legal research employs comparative approach. Comparison is made between Indonesian law and Islamic Law. It is found that Islamic law has different approach in addressing the issue of the legality of esthetic treatment provided by beauty clinics as compared to Indonesian law.  While the Indonesian law tends to liberate various kinds of esthetic treatment, Islamic law gives a restriction. By virtue of the principle of freedom of contract as intended in Article 1338 of the Indonesian Civil Code, any esthetic treatment can be carried out when it is made based on a valid contract between the contracting parties. On the other side, Islamic Law prohibits particular esthetic treatment especially when it falls under the category of “changing what Allah has created.”
