Authors: Colome Daniel , Da Costa Antonio , Calpey Jacob , Gilmore Nathan , Courtney Jonathan B.
Published: December 2024

Background: Short femoral stems have become increasingly popular in total hip arthroplasty (THA), offering potential advantages such as bone preservation and improved load transfer. The Everglade stem (Signature orthopedics Australia), a novel dual-tapered design, aims to enhance initial stability while minimizing complications such as subsidence and fracture. This study evaluates the short-term clinical and radiological outcomes of the Everglade stem. 
Methods: We conducted a retrospective review of 100 consecutive patients (41 men, 59 women; mean age 68 years) who underwent THA using the Everglade stem at the Delray beach surgical center, a physician-owned ambulatory surgical center (ASC), between December 2022 and January 2023. Pre-operative and post-operative hip disability and osteoarthritis outcome score (HOOS-Jr) data were collected. Radiological outcomes, including stem subsidence, periprosthetic fracture, and osteolysis, were assessed at the 6-week and 6-month follow-ups.
Results: The median follow-up was 161.5 days (IQR 43-187). The mean HOOS-Jr score improved from 57.07 pre-operatively to 86.03 at 6 weeks and 92.7 at the latest follow-up. No cases of stem subsidence, periprosthetic fracture, or osteolysis were observed at any follow-up. There were no stem revisions or postoperative infections. 
Conclusions: The Everglade stem demonstrated promising short-term outcomes, with significant improvements in patient-reported functional scores and no radiological complications. Longer-term studies are needed to evaluate the stem’s durability and long-term performance.

Authors: Pottanat Paul J. , Burnett Zachary , Kamalapathy Pramod , Park Joseph , Werner Brian
Published: December 2024

Background: Total ankle arthroplasty (TAA) and ankle arthrodesis (AA) are surgical treatment options for end-stage ankle arthritis. Providers should have a current understanding of the overall trends of these procedures as both are frequently used. Thus, the objective of the current study is to assess the trends in utilization, patient characteristics and outcomes after TAA and AA.
Methods: The PearlDiver Mariner database was used to capture patient characteristics and outcomes related to 2,494 patients who underwent TAA and 5,901 patients who underwent AA between 2010 and 2018.
Results: The incidence of TAA increased over the course of the study period (p<0.001) while the incidence of AA decreased (p=0.045). Length of stay (LOS) following AA significantly increased (3.02 vs 4.50, p<0.001) while LOS following TAA significantly decreased (2.78 vs 1.65, p=0.004). Furthermore, incidence of infections significantly increased following both procedures (AA 1.7% vs 6.6%, p=0.004; TAA 0.8% vs 2.7%, p=0.008). In 2018, patients who underwent TAA had a significantly decreased LOS (1.65 vs 4.50, p<0.001), risk of major complications (1.5% vs 3.9%, p=0.042), risk of any medical complication (7.1% vs 14.9%, p=0.004), and risk of infection (2.7% vs 6.6%, p=0.011) compared to those who underwent AA.
Conclusions: The present study demonstrates increased utilization of TAA for treatment of end-stage ankle arthritis compared to AA in recent years. Over the time period of this study, infection rates have increased and LOS has decreased for TAA while both infection rate and LOS have increased for AA.

Published: December 2024

Background: Blount's disease is a developmental condition defined by abnormal growth of the proximal posteromedial tibial physis, which causes progressive lower limb deformity. The deformity is primarily characterized by tibia vara, procurvatum, internal tibial torsion and limb shortening. To evaluate the outcome of treatment of Blount’s disease using circular external fixation Taylor spartial frame (TSF).
Methods: The limb deformity correction unit of the Orthopaedics and Trauma Department of University College Hospital, Ibadan conducted a 5-year retrospective assessment of patients who had Blount's disease correction using the TSF device between January 2019 and July 2023. The data was analyzed using the Social Sciences Statistical Package, Version 19.
Results: 42 patients were recruited with 68 limbs. 26 patients (62%) had both right and left lower limb deformities. The majority were young adolescent in the age group of 11–15 years. And a male-to-female ratio of 1:2.81. They all had TSF frame application, fibulotomy and metaphyseal (proximal tibia) corticotomy and subsequently had graduated adjustment of the frame until correction is achieved, following the prescription generated from the TSF software. The highest complication observed was pin site infection in 10 patients (23.8%).
Conclusions: The TSF device is considered one of the most reliable methods of achieving safe and accurate correction of the multi-planar deformities associated with severe and recurrent Blount’s disease.
A prospective cohort study investigating functional recovery in patients with avascular necrosis hip following total hip arthroplasty using a direct anterior versus direct posterior surgical approach in Indian population
Authors: Kumar Anand , Nama K. G. , Meena R. P. , Singh Rawat Sanjay
Published: December 2024

Background: This study examines the comparative outcomes of the Direct Anterior Approach (DAA) and Direct Posterior Approach (DPP) in patients undergoing Total Hip Arthroplasty (THA) for Avascular Necrosis of the hip.
Methods: A total of thirty patients were divided equally between the two surgical methods, with half number of patients undergoing DAA and half undergoing DPP. Key performance metrics, including Modified Harris Hip Score (MHHS), blood loss, operative time and length of hospital stay, were analysed to determine which approach offered superior postoperative recovery and patient satisfaction. A convenient sampling technique was used in our study. Epi Info 2023 software was used for statistical analysis of data. The study was conducted in Government medical college and associated group of hospitals. The study was conducted from 01/06/2022 to 30/06/2023.
Results: It shows that both approaches led to significant improvements in Modified Harris Hip Score (MHHS) postoperatively, with no statistically significant difference in the final hip function at various follow-up intervals. However, DAA required a smaller incision, making it cosmetically favourable but resulted in greater blood loss and longer operative time due to its technical complexity. DPP, on the other hand, was associated with faster operative time and slightly lower blood loss but had a higher risk of postoperative dislocation. Despite these differences, there was no significant difference in hospital stay duration or overall complication rates between the two groups.
Conclusions: While both DAA and DPP are effective for THA, the choice of approach may depend on surgeon expertise and patient-specific factors, with DAA offering better cosmetic outcomes and DPP offering a technically easier procedure with fewer blood loss complications. Further long-term studies are suggested to analyse any potential differences in complication rates beyond the early postoperative period.
Effectiveness of teriparatide in enhancing bone formation and reducing aseptic loosening risks post-hip arthroplasty in patients with avascular necrosis
Authors: Arbat Ashish , Thakkar Kandarp
Published: December 2024

Background: The hip joint's critical role in weight-bearing and mobility is often compromised by avascular necrosis (AVN), leading to osteoarthritis (OA). This study evaluates the impact of teriparatide, a synthetic parathyroid hormone analog, on bone formation and the risk of aseptic loosening in post-hip arthroplasty patients affected by AVN.
Methods: In this retrospective, single-centre study, 26 patients who underwent hip replacement surgery due to AVN between November 2021 and November 2023 were included. Participants were selected based on specific inclusion and exclusion criteria and received daily subcutaneous injections of teriparatide (20 μg) for six months. The study focused on assessing the efficacy of Teriparatide in mitigating prosthetic loosening and enhancing bone formation post-hip arthroplasty, alongside monitoring for adverse events.
Results: The cohort had a mean age of 37.63 years, predominantly male (77%). The median time for post-surgical pain onset was 31 days. After 3 months of teriparatide therapy, all patients showed a significant reduction in joint pain and swelling, with improved mobility. Radiographic evaluations demonstrated a decrease in previously observed radiolucent lines, indicating successful prosthesis integration. At the 6-month mark, tomosynthesis revealed no space between either the femoral head or hip components and the osteotomy load surfaces. No adverse events were reported during the therapy period.
Conclusions: Teriparatide-is a promising therapeutic agent for enhancing surgical outcomes in post-hip arthroplasty in patients with AVN. Its role in promoting bone formation and reducing aseptic loosening risks is significant, suggesting its potential in improving patient recovery and pre-empting postoperative complications.

Authors: Kulambi Vijayakumar S. , Mulla Mahammad A. M. , Gombi Praful R.
Published: December 2024

Closed reduction and percutaneous pin fixation techniques have been proposed as treatment strategies for displaced supracondylar humeral fractures (SCHFs) in children. Commonly lateral pinning and cross pinning techniques are utilised for fixation. However, controversy exists regarding the selection of the appropriate procedure. A prospective study with 24 cases of displaced fracture supracondylar humerus, treated by lateral pinning and cross pinning, was conducted between August 2022 and May 2024 at Department of Orthopaedics at J.J.M. Medical College, Davangere. Patients were treated with either the lateral entry pin alone or the cross pinning with a combination of lateral entry pin and medial entry pin. Age, gender, fractured side, duration of surgery, postoperative complications, surgical approach, direction of pin application (lateral or cross), and Modified Flynn grading system grade was noted for study outcome. No difference was found between lateral pinning and crossed pinning groups in terms of the grade of the modified Flynn grading system and complications like iatrogenic ulnar nerve damage, loss of reduction. Pin tract infection was seen in one patient.

Published: December 2024

Background: India like any other developing country is grappling with malnutrition cases due to avoidable factors. Nutritional deficiencies are prevalent in India and hyperpigmentation due to micronutrient deficiencies are common. Prevalence of B12 deficiency varies from 3% to 5% in the general population. This study aimed to determine the predictors of vitamin B12 deficiency among patients with skin hyperpigmentation AVBRH hospital, India.
Methods: A cross-sectional study involving 164 patients with skin hyperpigmentation at dermatology department of AVBRH hospital, India was conducted from 1st April to June 30th 2024. Interviewer-administered questionnaires were used to obtained data and analysis was done using Stata version.
Results: Of the 164 respondents, 73(44%) had vitamin B12 deficiency. The mean plasma vitamin B12 level was 201 pg/ml among strict vegans as compared to 314 pg/ml in non-strict vegans. Young age (OR=7.1; 95%CI: 1.120-2.737; p=0.009), distance more than 5 kilometers from nearest health facility (OR=3.8, 95%CI: 0.024-0.187; p=0.005), not employed (OR=2.5, 95%CI: 0.731-4.071; p=0.026), being strict vegetarian (OR=2.1, 95%CI: 0.141-1.050; p=0.002), and number of meals less than 3 per day (OR=9.1; 95%CI: 3.14-7.320, p=0.005) were independently associated with vitamin B12 deficiency among patients with skin hyperpigmentation at AVBRH hospital, India.
Conclusions: The prevalence of Vitamin B12 deficiency among patients with skin hyperpigmentation is high in India. Young age, residing more than 5 kilometers from health facility, being a strict vegetarian, having less than 3 meals per day and unemployment are predictive for vitamin B12 deficiency among patients with skin hyperpigmentation at AVBRH hospital.
A dive into gonorrhoea’s past
Authors: Salam Arisha
Published: December 2024

Gonorrhoea has a long-standing presence in human history, being recognized as one of the earliest sexually transmitted infections (STIs). While its exact origins are debated, there are references to a disease resembling gonorrhoea in ancient texts. The Chinese emperor Huang Ti mentioned a condition similar to gonorrhoea in his medical writings around 2600 BC. Additionally, some interpret passages in the book of Leviticus in the Old Testament as descriptions and precautions for gonorrhoea. Gonorrhoea, one of the oldest known STIs, has undergone significant changes in diagnosis and management over the centuries. Despite periods of decline, there has been a resurgence of the infection in recent decades. The emergence of drug-resistant strains and risky sexual behaviour may have contributed to this resurgence. To combat the spread of gonorrhoea, it's crucial to promote safe sex practices and provide comprehensive sex education, especially among teenagers. Timely adjustments to treatment regimens to address drug-resistant strains are also essential. By taking these steps, we can work towards reducing the prevalence and impact of gonorrhoea globally.
Cutaneous leiomyosarcoma of penile prepuce: A rare case
Authors: Mathew Blessy , Gupta Devika , Gahlot GPS
Published: December 2024

Cutaneous Leiomyosarcoma (atypical smooth muscle tumor) is an uncommon sarcoma of skin which typically presents in elderly Caucasian males as painful nodule over trunk and lower extremities. In view of its rarity, these cases go underdiagnosed in most of the patients. In this case report, the patient presented with phimosis and painful nodule over prepuce. This rare presentation made the clinical diagnosis even more challenging. Precise histopathology diagnosis with mention on location of lesion is of paramount importance. Based on location of the lesion, cLMS is categorized into three distinct groups with varying clinicopathological behavior and prognosis. The location of the lesion in the skin is the single most important prognostic factor. Pathological grading of tumor does not contribute to prognostication. Although superficial cLMS has good prognosis, dermal leiomyosarcoma has lower risk of local recurrence and distant metastasis than subcutaneous leiomyosarcoma. Cutaneous metastasis of extracutaneous (deep) leiomyosarcoma, which has the worst prognosis and least overall disease free survival, needs to be excluded in all cases of cLMS. Our case report highlights the significance and role of histopathological examination in the diagnosis of a very rare presentation of a rare disease.
Sedation and anesthesia in ambulatory ENT procedures – A review
Authors: Shetti Akshaya N
Published: December 2024

Ambulatory ENT (ear, nose, and throat) surgeries are increasingly common, driven by advancements in surgical techniques and anesthesia. The selection of appropriate sedation and anesthesia plays a pivotal role in the success of these procedures, ensuring patient safety, comfort, and optimal recovery. The choice between local anesthesia with sedation and general anesthesia depends on various factors, including the complexity of the procedure, patient comorbidities, and the surgeon’s preferences. A thorough understanding of airway management is essential, as ENT surgeries often involve shared airway cases, which can pose unique risks. Recent developments in anesthetic drugs, such as short-acting agents like propofol and remifentanil, have improved the efficiency of recovery in ambulatory settings, reducing the incidence of postoperative complications such as nausea and respiratory distress. In this article the author discusses the importance of preoperative assessment, patient selection, and postoperative care in optimizing outcomes. The latest practices and innovations, this review aims to provide a comprehensive overview of sedation and anesthesia techniques in ambulatory ENT procedures are included in this review.

Published: December 2024

Unilateral nasal mass may be a common presentation in children and young adults, and the majority of them are inflammatory polyps. But as the age advances, unilateral nasal complaints should alert the physician to the possibility of an underlying neoplastic mass lesion.

To study the etiopathology and clinical features of unilateral nasal mass in patients above 40 years of age.

The study was conducted in the department of otorhinolaryngology, Tezpur Medical College & Hospital. A total of 27 patients with unilateral nasal mass who are above 40 years of age are included in the study. The clinical features, radiological findings, and histological findings of all the patients were evaluated.

Among the 27 patients, 14 had non-neoplastic lesions compared to 13 neoplastic lesions. Inflammatory polyp was the most common non-neoplastic pathology, whereas inverted papilloma was the most common neoplastic lesion. Nasopharyngeal carcinoma was the commonest malignancy detected in the study.

Though inflammatory polyp constitutes the majority of cases of unilateral nasal mass, there is a considerable number of neoplastic lesions, especially when considered age above 40 years. Therefore, one should not directly jump into the conclusion of inflammatory polyp when an elderly patient presents with unilateral nasal mass; rather, a thorough diagnostic protocol should be employed to rule out any neoplastic lesion. The diagnosis of inflammatory polyp should be a diagnosis by exclusion only after other possible causes are excluded.

Published: December 2024

Endoscopic dacryocystorhinostomy (DCR) is a surgical remedy for nasolacrimal duct obstructions (NLDO), addressing symptoms like excessive tear secretion and swelling. This article presents an observational case report of a 60-year-old female with persistent tear secretion and a non-healing ulcer below the left medial canthus at the previously operated external DCR site, managed initially with antibiotics and secondarily with closure of the external wound. Endoscopic DCR was subsequently performed under local anesthesia, effectively resolving symptoms and facilitating recovery. Advantages of endoscopic over external DCR include no external scar, lower infection rates, and faster recovery. Imaging aids in precise anatomical assessment. The case underscores meticulous preoperative evaluation, surgical precision, and comprehensive postoperative care for optimal outcomes. In conclusion, endoscopic DCR proves pivotal in revising failed procedures, ensuring functional and aesthetic success in managing NLDO.

Authors: Deng Xia , Zhang Jie
Published: December 2024

To explore the impact of narrative nursing on psychological flexibility, fear of cancer recurrence and sleep quality in cancer patients. Methods: 100 cancer patients admitted to the Interventional Department of Jiangnan University Affiliated Hospital from January 2023 to January 2024 were selected as the research subjects. 100 patients were randomly divided into an observation group and a control group (50 cases each). The control group received basic nursing care, while the observation group received narrative care. After three months of nursing intervention, the psychological elasticity scores of the two groups of patients were compared [using the psychological elasticity scale] (RS-14)], changes in fear of cancer recurrence (FCR) (using the Fop-Q-SF scale) and sleep quality (using the PSQI scale). Results: Before the intervention, there was no statistical difference in the psychological flexibility, fear of cancer (FCR) and sleep quality (PSQI) scores between the two groups (P > 0.05); after the intervention, the RS-14 scores of the two groups were higher than before the intervention. And the observation group was higher (P < 0.05); the Fop-Q-SF and PSQI scores of both groups decreased, and the observation group was lower (both P < 0.05). Conclusion: Narrative nursing can effectively improve the psychological flexibility and sleep quality of cancer patients, reduce the fear of cancer recurrence, and has significant therapeutic effects.

Multistability and Complex Isotopy in Makam Music Analysis: The Link Between Cognition and Semiotics in Aesthetics of Turkish Music
Authors: Salvucci Peter
Published: December 2024

Multistability in perceptual psychology involves ambiguity or rivalry between two or more percepts of sensory stimuli. This phenomenon can be compared to the Greimassian concept of complex isotopy, where multiple terms of semantic content are simultaneously signified in the same reading of a text, providing multiple interpretational meanings. This study proposes that a key aesthetic principle of classical Turkish makam music involves the multistable perception of musical events, which in the semantic sense manifest as interoceptive, complex isotopies. The aesthetic of multiple subjective interpretations is examined in related traditional arts such as miniature art, poetry and theater. Generative theory is employed for compositional analysis in this study, as it reflects the cognitive apprehension of music. The principles of multistable perception as complex isotopy therefore provide a cognitive and aesthetic context to the author’s thesis proposal for a generative theory of makam music.

Published: December 2024

Infertility, which is defined as the failure to conceive after 12 months of regular, unprotected sexual activity, has a substantial impact on societal dynamics and frequently results in social stigma, especially against women. However, male infertility, which is defined as the inability of a male partner to impregnate a viable female, accounts for 30-40% of infertility cases. Genitourinary disorders such as varicocele, cryptorchidism, and testicular failure, and lifestyle factors like obesity, smoking, and alcohol intake are among the factors that contribute to male infertility. The purpose of this study is to investigate the types and frequency of anomalies in the sperm of 100 men who attended two reproductive clinics in Thiruvananthapuram, Kerala, India. Semen samples were collected, examined, and classified by WHO guidelines. People with leukocytospermia, reproductive tract infections, and genetic abnormalities were excluded. The most frequent abnormality was asthenozoospermia followed by oligoasthenozoospermia, whereas, teratoasthenozoospermia and oligoteratoasthenozoospermia were the least common, with no instances of isolated oligozoospermia or teratozoospermia. Considerable reductions in semen parameters were seen in certain infertility conditions when compared to normozoospermia. Sperm count, motility, and morphological defects showed moderate to strong correlations. Despite certain constraints, such as a limited sample size and exclusive emphasis on sperm analysis, the results offer a significant understanding of the subtle aspects of male infertility in the Indian subcontinent.

For the processing of coal mine methane into hydrogen-containing gas, a catalytic process of methane tri-reforming was studied under long-term testing conditions (800 ᵒC, 100 h). The tests were carried out using the actual composition of the methane-containing mixture recovered by mine drainage systems of the Raspadskaya mine (Kuzbass, Russia). Gas chromatographic analysis of coal mine gas showed that it contains the following components with an average concentration, vol.%: CH4 – 40.18, N2 – 36.30, H2O – 12.90, O2 – 9.77, CO2 – 0.88, C2H6 – 0.25 and C3H8 – 0.04. It was found that the average O/C molar ratio was 0.87, so CO2 addition to the methane-containing mixture was done to maintain the O/C ratio > 1.1 to ensure stable operation (without significant coke formation) during the catalytic process. Long-term catalytic tests have shown high parameters of the methane tri-reforming process, which were stable over the time of operation. At a temperature of 800 ᵒC, after 100 h of process using the Ce0.2Ni0.8O1.2/Al2O3 catalyst, the hydrogen yield was 85% at a methane conversion of 80%. A comparative analysis of the properties of fresh and spent Ce0.2Ni0.8O1.2/Al2O3 catalyst was performed using low-temperature nitrogen adsorption, powder X-ray diffraction, electron microscopy and thermal analysis. It was established that the mesoporous texture of the catalyst was retained, but the dispersion of the active component decreased. The Ce0.2Ni0.8O1.2/Al2O3 catalyst is resistant to thermal sintering and coking, which ensures no deactivation. The use of tri-reforming technology for the utilization of coal mine methane is a step towards “green” coal mining, ensuring sustainable development of society.
Laboratory Testing of Polymer Flooding by Hydrolyzed Poly(acrylamide) in High Salinity Conditions
Authors: Gussenov I. , Shakhvorostov A. , Ayazbayeva A. , Kudaibergenov S.E.
Published: December 2024

This study investigates the efficacy of high molecular weight hydrolyzed polyacrylamide (HPAM) solutions in enhancing oil recovery under high salinity conditions. The viscosity values of 0.25 wt.% HPAM solutions in 250 g∙L─1 brine with high content of divalent cations (Ca and Mg) were found to range from 11.5 to 12.6 cP for both 10% and 30% hydrolysis polymers. The displacement of 420-cP oil from sand pack models showed that injecting 3 pore volumes (PVs) of polymer solutions significantly increased the oil recovery factor, with an increment of 16─28% after the injection of 1 PV of water. The results of fractional flow calculations, along with sand pack flooding experiments, suggest that the oil recovery factor measurements are most likely overestimated by roughly 10%. An explanation for this is the plugging of pores by high molecular weight polymers. In fact, as the molecular weight increased from low to medium high and super high, it required the assumption of a much higher viscosity to achieve a fit between fractional flow predictions and actual polymer flood results. These findings highlight the potential of high molecular weight HPAM solutions to enhance oil recovery in high salinity environments and underscore the importance of using both sand pack flooding experiments and fractional flow calculations for comparing different polymers.

Published: December 2024

Abstract
This study aims to explore the role of Maqashid Syariah in enhancing business sustainability through the integration of Green Dynamic Capability and marketing strategies, focusing on PT Bank Muamalat in the Central Java province. A quantitative research approach was employed, using the Structural Equation Modeling (SEM) with Partial Least Squares (PLS) to analyze the relationships between variables. SEM PLS was chosen for its ability to evaluate complex models and measure latent variables that cannot be directly observed. Data were collected through a survey targeting 280 permanent employees of Bank Muamalat, using a saturated sampling technique to ensure comprehensive representativeness. The results of the study supported several hypotheses, showing that Maqashid Syariah positively influences marketing strategies and business sustainability. However, the impact of Green Dynamic Capability on innovation and business sustainability was not fully significant, indicating the need for further optimization in the implementation of green strategies. These findings suggest that Bank Muamalat can enhance its competitiveness by strengthening the application of Maqashid Syariah principles, particularly in marketing strategies, while simultaneously improving the integration of environmental sustainability initiatives. The study provides critical managerial implications, highlighting the importance of continuous monitoring and evaluation to ensure the effectiveness of these strategies in achieving long-term sustainability.

For 11 years, the staff of the Scientific Research Center “Botanical Garden” of SSU named after N.G. Chernyshevsky have been reintroducing a rare protected plant, Calophaca wolgarica (L. fil.) DC., into potentially suitable places in the Saratov Region. This species is considered
extinct in the region. Restoration of the species in the Saratov Region will expand its range, increase the biodiversity of the local flora and enrich
biogeocenoses. Seed material for the reintroduction of C. wolgarica was collected from natural cenopopulations in the Volgograd Region. In
2013–2015 the seeds were sown in Voskresensky (near the village of Ershovka) and Krasnoarmeysky (the villages of Kamenka, Mordovo, Rogatkino, Belogorskoye) districts of the Saratov right bank, in Perelyubsky (the village of Kutseba), Pugachevsky (near the village of Maksyutovo),
Fyodorovsky (the village of Dolina) districts of the left bank. In 2020, sowing was carried out in Pugachevsky (the villages of Maksyutovo, Solyanka)
and Yershovsky (the village of Novorozhenka) districts. Seedlings were planted in Krasnoarmeysky district (the villages of Rogatkino, Kamenka),
but they died in the year of planting. The seeds germinated in Pugachevsky, Fyodorovsky, Yershovsky and Krasnoarmeysky districts. To analyze
the results of C. wolgarica reintroduction in the Saratov region, the dynamics of the number of individuals, their ontogenetic and vitality structure were assessed in the created populations. The vitality structure was analyzed for individuals whose ontogenetic state was predominant in
terms of numbers for a specific year of observations. According to the results of the studies conducted in the period from 2016 to 2024, out of six
districts selected as sites for the reintroduction of C. wolgarica, three – Pugachevskiy, Fyodorovsky and Yershovsky – are suitable for the growth
of this species, and reintroduction is promising here. In two reintroduction populations from Pugachevskiy and Fyodorovsky districts, some of
the plants have reached the generative period. These populations are potentially capable of self-sustaining. The most favorable habitats for
C. wolgarica are located in the Pugachevskiy district.

The study of zoogeographic characteristics in combination with the use of modern methods for assessing phylogenetic relationships
allowed us to examine in detail the phylogeographic structure in scorpions of the genus Mesobuthus. In this work, to assess phylogenetic relationships, we used the decoded sequences of the COI gene fragment obtained by the team of authors in collaborative work and deposited in the
Genbank database (NCBI). Previously published results of zoogeographic studies, due to the lack of data on the distribution of species of this
genus, did not fully reflect the zoogeographic structure of the genus Mesobuthus. Therefore, the previously typified ranges of some species of the
genus Mesobuthus were revised in this work. For this purpose, specimens from the collection of the Zoological Institute of the Russian Academy of
Sciences were studied. To establish the zoogeographic position of the genus Mesobuthus, the biogeographic zoning of the Palaearctic, proposed by
Emelyanov A. F. and Krivokhatsky V. A., was chosen. According to the results of the study, five species groups (phillipsii, kirmanensis, eupeus, afghanus,
thersites) were identified in the genus Mesobuthus using phylogenetic analysis. The zoogeographic analysis identified two clusters consisting of eight elemental faunas. In addition, transition zones between the North Central Asian and Iranian-Mekranian elemental faunas, as well as
between the Khorasan-Girkan and South Turkana-Afghan elemental faunas were identified. In this study, based on the dates obtained, it was
found that in scorpions of the genus Mesobuthus, the hypothetical center of origin coincides with the modern chorological center, which is
the Iranian-Mekranian elemental fauna. Phylogenetic relationships between five groups of species prove that the genus Mesobuthus spread
from the Iranian-Mekranian elemental fauna to the north, forming the other elemental faunas. Also, it is established that the main processes
of Mesobuthus genus faunagenesis fall on the period from the middle Miocene to the late Pliocene.

Introduction: Lung contusion is a common condition often resulting from blunt trauma, and it is connected with substantial health complications and risk of death; therefore, timely diagnosis and treatment are essential. Ultrasonography is a valuable technique that significantly improves medical care, offering time efficiency and lifesaving benefits. This study aimed to evaluate lung contusion by comparing the use of ultrasound and computed tomography (CT) scan during the initial 24 hr of intensive care unit (ICU) hospitalization.
Methods: Eighty patients with blunt chest trauma were enrolled in this study. Each patient underwent both chest CT scan and lung ultrasound examinations. Lung ultrasound was performed in 6 anatomical regions on each lung (anterior-superior, anteriorinferior, lateral-superior, lateral-inferior, posterior-superior, and posterior-inferior). Lung contusion was identified by observing localized pulmonary effusion along with disrupting the lung parenchyma. To evaluate the extent of lung damage, the ratio of partial pressure of oxygen in arterial blood to the fraction of inspired oxygen concentration (PaO2/FiO2 ratio) was utilized, while the extent of lung involvement was classified using the blunt pulmonary contusion score (BPC-18 score).
Results: In this study, lung ultrasonography demonstrated a sensitivity of 93.6% for detecting lung contusions, with a specificity of 94.1%, positive predictive value (PPV) of 98.3%, negative predictive value (NPV) of 80%, and overall accuracy of 93.7%. Specifically, for the right lung, these measures were 90.9%, 96%, 98%, 82.7%, and 92.5%, respectively. For the left lung, the corresponding values were 88%, 96.6%, 97.7%, 82.8%, and 91.2%. The receiver operating characteristics (ROC) curve assessed the sensitivity and specificity of ultrasound in diagnosing lung contusions within the first 24 hr of ICU admission. The area under the curve (AUC) for this assessment was 0.939, indicating high diagnostic accuracy.
Conclusion: While CT remains the standard for evaluating lung contusions, its accessibility may be limited due to various circumstances, especially during hemodynamic instability. In these situations, ultrasound is highly valuable in diagnosing lung contusions with exceptional sensitivity, specificity, and diagnostic accuracy. Chest ultrasound emerges as an essential, noninvasive, and safe diagnostic tool at the bedside in the ICU for detecting lung contusions.
On the Rhetoric Manual Hortulus Tullianus
Authors: Kyselov Roman
Published: December 2024

Many philological courses from 17th and 18th-century Ukrainian colleges remain unattributed or insufficiently explored. Sometimes, the content and material features of manuscripts provide data for their attribution. The analysis of the rhetorical manual Hortulus Tullianus, which was considered a 17th-century Kyiv-Mohyla rhetoric course, also gave grounds to attribute the record differently. The choice of topics, characters, and objects for the rhetorical examples indicates that the lectures were indeed written and used in the Ukrainian cultural space. This is evidenced by the detailed consideration of the Immaculate Conception of the Virgin Mary, the mention of the Dnipro River, attention to the life of St. Mykola Sviatosha, and the presence of images of St. Andrew the Apostle and St. Prince Volodymyr. However, some examples in the text describe the late phase of the Northern War. Combined with the absence of Hetman Ivan Mazepa’s name, this fact suggests that the text was created between 1709 and 1721. The length of the text, the indicated period of the lectures’ beginning (spring), watermarks, and some other data suggest that Hortulus Tullianus is a rhetorical supplement to the poetics course, most likely dating from the mid-1710s and belonging to the heritage of Chernihiv College.The later use of these lectures at the College of Pereiaslav is a separate story. Mykhailo Isaievych’s rhetoric course of the 1740/1741 academic year almost completely reproduced the materials of Hortulus Tullianus. However, in Pereiaslav, these short rhetorical instructions served as a yearlong course. It is possible that the Pereiaslav lecturer supplemented the main presentation with examples of speeches and appendices that were not included in the body of the course and were offered for recording separately. The paper concludes with a detailed table of contents of Hortulus Tullianus.
Joasaf Krokovskyi’s Oration on the Demise of Inokentii Gizel (1683)
Authors: Kyselov Roman
Published: December 2024

The publication features a funeral oration composed in 1683 by Joasaf Krokovskyi, then a professor of rhetoric, in honor of Inokentii Gizel, the deceased archimandrite of the Kyiv Cave Monastery. The work is included in the rhetoric course «Penarium Tullianae eloquentiae...», which was delivered at the Kyiv-Mohyla College during the 1683/1684 academic year. The introductory article is followed by the original text in Polish and its Ukrainian translation, accompanied by necessary comments.In the rhetoric course, Krokovskyi’s oration is used as an illustrative sample in the theoretical unit on rhetorical figures. In line with the traditions of Baroque literature, the author selects a recurring image that determines the sequence of the presentation: here, this role is played by the clock face as an allegory of human life. Another point shaping the work’s figurative system and serving as a source of rhetorical argumentation is the emblem depicting a crayfish dragging the world on its back. Most likely, it was borrowed from Joachim Camerarius’ emblematic collection «Symbolum et emblematum centuriae quatuor». It is noteworthy that Krokovskyi’s Polish text is not overloaded with Latin inclusions, which reflects his linguistic and stylistic preferences related to the use of Polish.Since the biography of the archimandrite of the Kyiv Cave Monastery and a prominent figure in the Mohylean circle, Inokentii Gizel, remains incomplete and includes hypothetical information, this oratorical piece is also important as a historical source. In particular, it is the first known text to name some of Gizel’s places of study. The work also indirectly confirms the fact of Vilnius origin of the future archimandrite and contains an indication of his two terms as a philosophy lecturer at the Kyiv-Mohyla College.
