Synthesis, crystal structure and magnetic properties of coordination compounds of Mn(NCS)2 with the 3-bromopyridine ligand
Authors: Krebs Christoph , Jess Inke , Ceglarska Magdalena , Rams Michał , Näther Christian 
Published: May 2022

Abstract
Reactions of Mn(NCS)2 with 3-bromopyridine in acetonitrile lead to the formation of Mn(NCS)2(3-bromopyridine)4 (1) and Mn(NCS)2(3-bromopyridine)2(MeCN)2 (2) that were characterized by single crystal X-ray diffraction. Compounds 1 and 2 consist of discrete complexes, in which the Mn(II) cations are octahedrally coordinated by two trans-N-bonding thiocyanate anions and four pyridine (1) or two pyridine and two acetonitrile ligands (2). Thermoanalytical measurements on 1 and 2 have shown that upon heating half of the 3-bromopyridine co-ligands from 1 or both acetonitrile ligands from 2 are removed leading to a crystalline phase with the composition [Mn(NCS)2(3-bromopyridine)2]
n
(3-II). From dry n-butanol a phase with the same composition was obtained (3-I) that corresponds to a polymorphic or isomeric form of 3-II. Crystal structure analysis of 3-I shows that in this form the Mn cations are linked by pairs of anionic ligands into linear chains. The results of magnetic measurements on 3-I show antiferromagnetic interactions along the chains and the analysis of the magnetic susceptibility using the Fisher model for chains gave a J value of −5.76(5) K.

AbstractThis research aims to investigate the aging resistance of asphalts from different crude oils based on molecular structure and rheological properties. The average molecular structure of five types of asphalt from different crude oils were analyzed with the element analyzer, nuclear magnetic resonance, gel permeation chromatograph, and the improved Brown–Ladner method. The rheological properties of the asphalts were tested by the dynamic shear rheometer before and after laboratory aging. The antiaging properties of the asphalts were evaluated by the rheological aging index (RAI). The findings indicate that there were significant differences in the molecular structures among the five types of asphalt. The asphalt with the least hydrogen–carbon ratio (H/C), the largest aromatic carbon ratio (fA), and the largest condensation index (CI) had the lowest rate of decline in rheological properties and therefore, the best antiaging performance. The H/C, fA, and CI had good correlations with RAI, which indicated that it was feasible to use these molecular structure parameters to evaluate the differences in the aging resistance of various asphalts.

Purpose
To externally validate the performance of the S-GRAS score and a model from the Surveillance, Epidemiology, and End Results (SEER) database in a Chinese cohort of patients with adrenocortical carcinoma (ACC).

Methods
We first developed a model using data from the SEER database, after which we retrospectively reviewed 51 ACC patients hospitalized between 2013 and 2018, and we finally validated the model and S-GRAS score in this Chinese cohort.

Results
Patient age at diagnosis, tumor size, TNM stage, and radiotherapy were used to construct the model, and the Harrell’s C-index of the model in the training set was 0.725 (95% CI: 0.682–0.768). However, the 5-year area under the curve (AUC) of the model in the validation cohort was 0.598 (95% CI: 0.487–0.708). The 5-year AUC of the ENSAT stage was 0.640 (95% CI: 0.543–0.737), but the Kaplan–Meier curves of stages I and II overlapped in the validation cohort. The resection status (P = 0.066), age (P=0.68), Ki67 (P = 0.69), and symptoms (P = 0.66) did not have a significant impact on cancer-specific survival in the validation cohort. In contrast, the S-GRAS score group showed better discrimination (5-year AUC: 0.683, 95% CI: 0.602–0.764) than the SEER model or the ENSAT stage.

Conclusion
The SEER model showed favorable discrimination and calibration ability in the training set, but it failed to distinguish patients with various prognoses in our institution. In contrast, the S-GRAS score could effectively stratify patients with different outcomes.

Objective
To compare the presentation and evolution of primary aldosteronism (PA) in the elderly (≥65 years) and young patients (<65 years).

Methods
A retrospective multicenter study was performed in 20 Spanish hospitals of PA patients in follow-up between 2018 and 2021.

Results
Three hundred fifty-two patients with PA <65 years and 88 patients ≥65 years were included. Older PA patients had a two-fold higher prevalence of type 2 diabetes, dyslipidemia, and cerebrovascular disease, but these differences disappeared after adjusting for hypertension duration. At diagnosis, diastolic blood pressure was lower than in young patients (83.3 ± 11.54 vs 91.6 ± 14.46 mmHg, P < 0.0001). No differences in the rate of overall correct cannulation (56.5% vs 42.3%, P = 0.206) or the diagnosis of unilaterality (76.9% vs 62.5%, P = 0.325) in the adrenal venous sampling (AVS) was observed between the elderly and young groups. However, there was a lower proportion of PA patients who underwent adrenalectomy in the elderly group than in the younger group (22.7% (n  = 20) vs 37.5% (n  = 132), P = 0.009). Nevertheless, no differences in the rate of postsurgical biochemical (100% (n  = 14) vs 92.8% (n  = 90), P = 0.299) and hypertension cure (38.6% (n  = 51) vs 25.0% (n  = 5), P = 0.239) were observed between both groups.

Conclusion
Older patients with PA have a worse cardiometabolic profile than young patients with PA that it is related to a longer duration of hypertension. However, the results of the AVS, and adrenalectomy are similar in both groups. Therefore, the management of elderly patients with PA should be based not only on age, but rather on the overall medical, physical, social, and mental characteristics of the patients.

Authors: Laskova A. I. , Lopatin Yu. M. 
Published: May 2022

Aim. Validation and evaluation of psychometric parameters of the Russian-language version of the Coronary Artery Disease Education Questionnaire II (CADE-Q II) in patients with chronic coronary syndromes (CCSs).Material and methods. The study involved 303 patients with stable coronary artery disease (CAD) who were hospitalized in the cardiology department in April-November 2021. All patients admitted underwent a standard examination and treatment, adopted in the management of patients with CCSs. In addition, we analyzed socio-demographic parameters (marital status, education level, occupation, disability, income level), quality of life (using SF-36 and SAQ questionnaires), levels of anxiety and depression (HADS scale), personality type D (DS-14 questionnaire), adherence to treatment (four-item Morisky-Green Medication Adherence Scale), Charlson comorbidity index, The Self Care of Coronary Heart Disease Inventory (SC-CHDI), and CADE-Q II. The validation process of new questionnaire was carried out in several stages as follows: translation, pilot testing, reliability assessment, constructive and criterion validity assessment.Results. Test-retest reliability of the questionnaire’s scales was 0,81, while Cronbach’s alpha varied from 0,613 to 0,877, which indicates its sufficient reliability. The confirmatory factor analysis confirmed the correspondence of the obtained model to the experimental one. The criteria validity of the questionnaire revealed correlation between the scales with the level of patient’s general education (r=0,391, р<0,01), “selfcare confidence” scale of the SC-CHDI (r=0,251, р<0,05), “Vitality” component of the SF-36 (r=0,225-0,284, р<0,05), “Mental Health” component of the SF-36 (r=0,308, р<0,01). In addition, a weak negative relationship was found between the blocks “Physical exercises” and “Psychosocial risks” with age (r=-0,237, p<0.05 and r=-0,229, p<0.05, respectively).Conclusion. The Russian-language version of the CADE-Q II has sufficient psychometric indicators and is a valid tool for assessing the self-care ability of patients with CAD.

Aim. To assess the level of various cardiac biomarkers and the volume of epicardial adipose tissue (EAT) in patients with heart failure (HF) depending on the type of atrial fibrillation (AF).Material and methods. This prospective observational study included 69 patients with symptomatic AF, as well as with manifestations of New York Heart Association (NYHA) class II-III HF. All patients were examined before catheter ablation for AF. The following investigations were performed: echocardiography, computed tomography, myocardial perfusion scintigraphy, immunochemical analysis of cardiac biomarkers (brain natriuretic peptide (BNP), high-sensitivity troponin I (hs-TnI)), as well as biochemical analysis of high-sensitivity C reactive protein (hsCRP). Patients were divided into 2 groups, depending on the AF type, into paroxysmal and non-paroxysmal (persistent and long-standing persistent).Results. The analysis included 69 patients with various AF types and symptomatic HF. There were significantly more patients with HF confirmed by an elevated BNP level in the group with non-paroxysmal type (27 (71%) vs 5 (16%), p<0,00001). Comparison analysis showed that in group 2 the mean BNP level was significantly higher than in group 1 (135,5 pg/ml [75,2;303,2] vs 40 pg/ml [20,7;56,9], respectively, p<0,00001). The hs-TnI level was higher in group 2 (2,5 [1,7;5,1] vs 1,9 [0,8;3,9], respectively, p=0,19), but there was no significant difference between the groups. The level of hsCRP did not differ in both groups. In group 1, the EAT volume was 139 [117,5;171] vs 169 [130;209,5] in group 2 (p=0,03).Conclusion. The type of AF plays a role in the interpretation of cardiac specific enzymes, and BNP levels and EAT volume are higher in patients with the non-paroxysmal form.

Published: May 2022

Amaç: İnce barsak atrezi/stenozu nedeniyle takip edilen hastaların morbidite ve mortalite nedenlerini ve sağ kalımı etkileyen faktörleri araştırmak, büyüme ve gelişmelerini incelemektir.
Gereç ve Yöntemler: 2002-2012 yılları arasında duodenal, proksimal jejunoileal, distal jejunoileal atrezi/stenoz nedeniyle takip edilen 85 hasta çalışmaya dâhil edildi. Hastaların cinsiyeti, prenatal tanısı olup olmadığı, tanı konulma zamanı, doğum haftası, kilosu, anne yaşı, klinik özellikleri, eşlik eden anomaliler, ameliyattaki bulgular, ameliyat sonrası hastanede kalış süresi ile ilgili veriler kaydedilerek morbidite ve mortaliteyi etkileyen faktörler ve büyüme gelişme parametreleri incelendi.
Bulgular: Çalışmaya dâhil edilen 85 hastanın 44’ü kız, 41’i erkekti. Hastaların 35’inde duodenal, 29’unda proksimal jejunoileal, 21’inde ise distal jejunoileal atrezi/stenoz mevcuttu. Hastaların %58’inde prematürite mevcuttu. Duodenal atrezi/stenozu olan hastalarda eşlik eden konjenital anomali oranı %74,
jejunoileal atrezi/stenozu olan hastalarda %42 idi. Çalışma grubunda mortalite oranı %18, erken ve geç dönem komplikasyon oranı %20 olup, en sık görülen komplikasyon sepsisti. Mortalite ile sonuçlanan hastalarda eşlik eden konjenital anomali varlığı (%100), düşük doğum ağırlığı (%93) ve prematürite sıklığının (%80) artmış olduğu görüldü. Hastalar büyüme gelişme açısından incelendiğinde duodenal atrezi/stenoz grubunda vücut ağırlığı ve kilo persentillerinin normal değerlerde olduğu, jejunoileal atrezilerde ise boy persentillerinin düşük olduğu tespit edildi.
Sonuç: İnce barsak atrezisi/stenozu nedeniyle tedavisi yapılan ve kaybedilen hastalarda prematürite, düşük doğum ağırlığı ve eşlik eden konjenital anomali sıklığının artmış olduğu bulunmuştur. Geç dönem komplikasyon oranının düşük olmasının, hastalardaki takip düzensizliğine bağlı veri eksikliğinden kaynaklandığı düşünülmüştür. Jejunoileal atrezi/stenozu olan hastalarda boy persentilleri düşük olup çalışma grubundaki tüm hastaların ameliyat sonrası dönemde beslenme ve büyüme-gelişme açısından yakın takip edilmesini öneriyoruz.
A rare case of periprosthetic supracondylar fracture with fracture medial condyle of femur after total knee arthroplasty
Authors: Palit Sukanya 
Published: May 2022

<p>Periprosthetic supracondylar fracture with fracture of medial condyle of femur after total knee arthroplasty (TKA), is of rare incidence. The risk factors include morbid obesity, increased varus deformity after primary TKA, osteopenia, prolonged use of corticosteroids or even trivial trauma leading to stress fractures. We reported a case of periprosthetic supracondylar fracture with fracture medial condyle of right femur after TKA in a patient of rheumatoid arthritis, with severe varus right knee and morbid obesity. X rays of knee revealed the periprosthetic supracondylar fracture with anterior femoral notching; CT scans revealed supracondylar fracture with severe comminuted fracture of right prosthetic medial condyle. Revision arthroplasty was done with augmented long-stem implant and patient was discharged on the 10<sup>th </sup>post-operative day. Knee movement at 6 months was 0-120 degrees with satisfactory outcome scores on follow-up. Periprosthetic supracondylar fracture with fracture medial condyle of the femoral implant requires immediate diagnosis and treatment; revision arthroplasty is mandatory if associated with morbid obesity, osteopenia and varus knees, after primary TKA. Obesity leads to excessive joint overloading, which together with varus malalignment and poor bone stock, may lead to component loosening, requiring revision arthroplasty. Weight reduction is necessary before primary TKA to improve the functional outcomes and reduce the incidence of revision arthroplasty. </p>

Published: May 2022

Background: Feline Infectious Peritonitis (FIP) is a disease caused by Feline Corona Virus (FCoV) which can cause acute respiratory disorders or enteritis in cats. Purpose: studying FIP and the treatment that must be given to patients who are positive for FIP. Case Analysis: This case was found at the Petvet Animal Clinic Jakarta in a British Short Hair Cat. Examination and treatment will be carried out on May 22, 2021 – June 3, 2021. The examination method is carried out by clinical examination and laboratory examination. Clinical examination was carried out by inspection and palpation methods. Laboratory examinations were carried out by examining the FCoV Rapid test, blood examination, abdominocentesis, abdominal fluid examination and polymerase chain reaction. Based on the results of the clinical examination, FCoV rapid test, hematology and Rivalta testing, it can be concluded that the FIP case in cat at the Petvet Animal Clinic belongs to the wet type (effusive) FIP. Conclusion: It is necessary to carry out other supporting diagnoses such as ELISA (Enzyme-Linked Immunosorbent Assay) and PCR (Polymerase Chain Reaction) testing. There is no cure for this FIP case, but symptomatic and supportive therapy is very helpful to reduce clinical symptoms and increase body endurance.

Abstract
The study of Triassic paleontology and stratigraphy of various regions of northeastern Russia and adjacent Arctic shelf is essential not only for improving and refining zonal biostratigraphic schemes, interregional and global correlation of Triassic deposits, and resolving problems of stratigraphic boundaries but also for developing and substantiating a new generation of Triassic stratigraphic schemes, which could serve as the stratigraphic basis for different regional and detailed geological investigations of the Arctic. The results of the study were used to improve existing zonal scales based on various groups of fauna and palynomorphs, develop a more detailed biostratigraphic subdivision of the Triassic, and characterize individual horizons using both terrestrial and marine palynomorphs. The zonal scales are calibrated to each other and to the regional zonal scale of the Triassic of Siberia and northeastern Russia, which provides the subsequent correlation with the International Chronostratigraphic Chart of the Triassic System. The set of coeval zonal scales for the Triassic of Kotelny Island sections based on ammonoids, nautiloids, coleoids, bivalves, brachiopods, and foraminifers and the analysis of microphytoplankton and terrestrial palynomorph assemblages are a useful tool for detailed subdivision and correlation of the eastern part of the Laptev Sea shelf and adjacent regions of northeastern Russia.
Epithermal Au–Ag–Se–Te Deposits of the Chukchi Peninsula (Arctic Zone of Russia): Metallogeny, Mineral Assemblages, and Fluid Regime

Abstract
Numerous epithermal Au–Ag deposits and ore occurrences of the Chukchi Peninsula are localized in the Cretaceous Okhotsk–Chukotka (OCVB) continent-marginal and Late Jurassic–Early Cretaceous Oloi (OVB) island arc volcanic belts and in Early Cretaceous postcollisional volcanic troughs. Volcanotectonic depressions, calderas, and volcanic domes control the location of the deposits. The orebodies of the deposits are quartz–adularia veins, sometimes en-echelon ones forming extending vein zones, as well as isometric and linear stockworks. The auriferous veins of most deposits display complex breccia–crustification structures. The vein ores have rhythmically and colloform–banded structures, with a predominantly fine distribution of ore mineral grains, often with banded clusters of ore minerals (ginguro). Native gold is of low fineness; the dispersion of this index varies from low to high. Acanthite is widespread in the ores. Its highest contents are specific to deposits with the repeated redistribution of substance (Kupol, Corrida, and Valunistoe). Based on the results of mineralogical studies, most of the epithermal Au–Ag deposits of the Chukchi Peninsula can be assigned to the Se type. The ores of some deposits (Valunistoe, Dvoinoe, etc.) contain both Se and Te minerals. The telluride-richest sites of the Sentyabr’skoe and Televeem deposits are far from the main orebodies. Most of the Chukchi epithermal Au–Ag deposits have many common characteristics (low and moderate temperatures of fluids, low fluid salinity, domination of carbon dioxide over methane, etc.) typical of low-sulfidation deposits. The maximum temperatures and salinity are specific to fluids in the Central Chukchi sector of the OCVB and in the Baimka zone of the OVB, and the minimum ones are typical of fluids in the East Chukchi flank zone and inner zone of the OCVB. The average salinity of mineral-forming fluids in the inner zone of the OCVB is half as high as the salinity of fluids in the East Chukchi flank zone of this belt, although the sulfate content is higher. At the same time, the fluids in the inner zone of the OCVB are richer in carbon dioxide and bicarbonate ion than the fluids in the East Chukchi flank zone of this belt. The fluid inclusion data permit the Vesennee deposit (Baimka zone) to be regarded as an intermediate-sulfidation one and suggest the presence of epithermal high-sulfidation deposits in the inner zone of the OCVB.
