Argyreia nervosa Mitigates Insulin Resistance in Liver via IR/IRS-1 Mediated Signaling in Streptozotocin-Induced Type-2 Diabetic Rats

Argyreia nervosa, commonly known as Hawaiian baby woodrose or wooly morning glory, is a plant native to India and is also found in various parts of the world. It is known for its seeds, which have been used traditionally in Ayurvedic and traditional medicine systems for various diseases. The study was aimed at assessing the effect of Argyreia nervosa on insulin signaling molecules of the liver in streptozotocin (STZ)-induced experimental type-2 diabetic rats. Healthy adult male Wistar albino rats -150-180 days old weighing 180-200g was used for the study and divided as Group I - Normal rats; Group II – type-2 diabetic rats; Group III -Diabetic rats + A. nervosa 500 mg/kg b.wt; Group IV-Normal rats + A. nervosa 500 mg/kg b.wt. Fasting blood glucose, and fasting serum insulin were measured by calorimetric methods. Further mRNA expression analysis of insulin receptor (IR) was measured in control and treated animals by quantitative Ream Time PCR analysis. A. nervosa root extract significantly reduced fasting blood glucose and serum insulin concentrations in STZ-induced rats compared with control. In addition, mRNA expression of IR showed a one-fold increase in the expression which shows that A. nervosa is involved in the regulation of insulin signaling in the liver and thereby reduces insulin resistance and type-2 diabetes. Our study concludes that A. nervosa root extract has a significant role on insulin signaling molecules thereby it reduces hyperglycemia and hyperinsulinemia via insulin receptor-mediated pathways. Hence, A. nervosa may be considered as one of the therapeutic natural antidiabetic drugs.

Cardiac Disease Diagnosis Using K-Nearest Neighbor Algorithm: A Study on Heart Failure Clinical Records Dataset

This article introduces an approach to diagnose heart diseases utilizing the K-Nearest Neighbor algorithm and diverse correlation filters for selecting the most pertinent attributes. Results high- light that meticulous filter selection enhances survival predictions in patients with heart diseases. Employing K = 5 and correlation filter CF = 0.1, key attributes for classification were identified as anemia, high blood pressure, serum creatinine, and sex. Omitting the 'time' attribute led to information loss but was crucial to prevent biases and generalize predictions across various clinical scenarios. Utilizing these classification parameters, we designed an Android mobile application called “Heart Info System”, functioning as an artificial intelligence service. It employs the K-Nearest Neighbor algorithm with optimal parameters to evaluate the probability of survival in the progression of heart disease. The main activity of the application retrieves data from a Firebase database. While the study results show promise, the accuracy of the application may be influenced by inaccurate or incomplete input data. Nevertheless, this application has the potential to improve the early detection of heart diseases, paving the way for life-saving interventions.

Whole blood: total blood product ratio impacts survival in injured children.

Some studies in both children and adults have shown a mortality benefit for the use of low titer group O whole blood (LTOWB) compared to component therapy for traumatic resuscitation. Although LTOWB is not widely available at pediatric trauma centers, its use is increasing. We hypothesized that in children who received whole blood after injury, the proportion of whole blood in relation to the total blood product resuscitation volume would impact survival. The trauma database from a single academic pediatric level 1 trauma center was queried for pediatric (age < 18 years) recipients of LTOWB after injury (years 2015-2022). Weight-based blood product (LTOWB, red blood cells, plasma and platelet) transfusion volumes during the first 24 hours of admission were recorded. The ratio of LTOWB to total transfusion volume was calculated. The primary outcome was in-hospital mortality. Multivariable logistic regression model adjusted for the following variables: age, sex, mechanism of injury, injury severity score, shock index, and Glasgow Coma Scale (GCS) score. Adjusted odds ratio representing the change in the odds of mortality by a 10% increase in the LTOWB:total transfusion volume ratio was reported. There were 95 pediatric LTOWB recipients included in the analysis, with median (IQR) age of 10 years (5-14), 58% male, median (IQR) injury severity score of 26 (17-35), 25% penetrating mechanism. The median(IQR) volume of LTOWB transfused was 17 (15-35) mL/kg. LTOWB comprised a median (IQR) of 59% (33-100) of the total blood product resuscitation. Among patients who received LTOWB, there was a 38% decrease in in-hospital mortality for each 10% increase in the proportion of WB within total transfusion volume (p < 0.001) after adjusting for age, sex, mechanism of injury, injury severity score, shock index, and GCS score. Increased proportions of LTOWB within the total blood product resuscitation was independently associated with survival in injured children. Based on existing data that suggests safety and improved outcomes with whole blood, consideration may be given to increasing the use of LTOWB over CT resuscitation in pediatric trauma resuscitation.

High red blood cell folate is associated with an increased risk of diabetes death among a hypertensive cohort

The relationship between folate and diabetes remains inconclusive, possibly because of folate measured differentially between studies. Interference from mandatory folic acid fortification (FAF) has also been blamed. With both folate intake and circulating concentration measured, we assessed the relationship between folate and the risk of diabetes death in a hypertensive cohort established before FAF. We hypothesized that the association between folate and diabetes death is measurement dependent. We analyzed the data of 3133 hypertensive adults aged ≥19 years who participated in the Third National Health and Nutrition Examination Survey (1991–1994) and were followed up through December 31, 2010. Hazard ratios of diabetes death were estimated for participants with high (4th quartile) folate compared with those with moderate (2nd and 3rd quartiles) or low (1st quartile) concentrations of folate. Dietary folate intake, total folate intake (including folate from supplements), serum, and red blood cell (RBC) folate were measured. After 42,025 person-years of follow-up, 165 diabetes deaths were recorded, and a dose-response positive association was observed between diabetes death and RBC folate. The adjusted hazard ratios of diabetes death were 1.00 (reference), 1.80 (95% CI. 1.52–2.13), and 2.33 (1.80–3.02), respectively, for hypertensive adults with low, moderate, and high RBC folate. No association was detected between diabetes death and serum folate concentration, folate intake, or either dietary intake or total intake. With minimized interference from FAF, neither dietary nor serum folate was associated with diabetes death, but elevated RBC folate was associated with a high risk of diabetes deaths among hypertensive patients.

Results: In present study BMI, systolic blood pressure, diastolic blood pressure, Troponin I, cholesterol, triglycerides, LDL, HDL blood serum levels of male and female in Group A and Group B were measured, the comparative analysis of above biomarkers showed a significant p-Value ≤ 0.05 change (0.02 ± 0.01, 183.01 ± 0.02, 120.01 ± 0.02, 87.01 ± 0.03, 44.01 ± 0.01), (0.02 ± 0.01, 172.01 ± 0.02, 130.01 ± 0.01, 88.01 ± 0.03, 42.01 ± 0.04), (0.39 ± 0.04, 272.01 ± 0.02, 180.01 ± 0.01, 138.01 ± 0.03, 37.01 ± 0.01) and ( 0.37 ± 0.04, 282.01 ± 0.02, 184.01 ± 0.01, 141.01 ± 0.03, 36.01 ± 0.01) were measured respectively. Conclusions: The present study found that there were notable significant p-value &lt;0.05 differences in the blood serum levels of BMI, systolic and diastolic blood pressure, Troponin I, cholesterol, triglycerides, LDL, and HDL in both the male and female groups in Groups A and B

Lagoviruses in European brown hares, first serologic evidence for RHDVa

AbstractSerological tests for the presence of antibodies to European brown hare syndrome virus and rabbit hemorrhagic disease virus type a and type 2 were performed on 275 samples of blood serum from the European brown hare by hemagglutination inhibition test and enzyme-linked immunosorbent assay. The presence of antibodies against European brown hare syndrome virus was 28% in the Czech Republic while in the Slovak Republic between 9–33%. Furthermore, the results showed the possibility of interspecies transmission, both rabbit hemorrhagic disease virus type a and rabbit hemorrhagic disease virus type 2 on the European brown hare. In case of RHDVa it is the first documented interspecies transmission, which has not yet been described. This study improved our knowledge about circulation of RHDV in Central European ecosystems and its possible ability to cross interspecies barriers. However, from an epizootiological point of view, it is likely European brown hare is not a significant source of RHD infection for domesticated rabbits.

Cholesterol and Blood Profile of Bali Cattle Fed Chromolaena odorata Weed with Rice Straw as Basal Feed

This study aims to determine the effect of the level of C. odorata (CO) silage-based concentrate on the blood profiles of Bali cattle. Three male Bali cattle (initial 2 years old with CV = 19,28%) were randomly assigned to one of three meals: rice straw and concentrates containing C.odorata silage 30% (RCO30) or C.odorata silage 40% (RCO40) or C.odorata silage 50% (RCO50), respectively, using a 3 x 3 Latin Square Design. The was no significant effect between treatments (P&gt; 0.05) on blood cholesterol (195.74-220.49 mg/dL), blood urea (48.41-49.44 mg/dL), total blood plasma (6.08-6.93 g/dL), blood haemoglobin (Hb; 18.18-18.92 g/dL), hematocrit levels (45.56-53.03%), erythrocytes (7.06-8.24 106/l), and leucocytes (8.56-8.84/l). Blood glucose levels, however, differed significantly (P&lt;0.05) between treatment. Feeding Bali cattle with different levels of C.odorata-based concentrate resulted in the same effect on all blood parameters except blood glucose. Therefore, it is recommended that the use of C.odorata in a ration of Bali cattle can be up to 50%.

Динамика на някои биохимични показатели при две местни породи овце в зависимост от сезона, надморската височина и наличието на паразити

The aim of the present study is to evaluate the values of some enzymes and metabolites - ALT, AST, ALP, serum iron and glucose of two herds of Bulgarian native sheep breeds raised at different altitudes, depending on the season, their body condition score (BCS) and the presence of gastrointestinal parasites. The research was conducted with 20 animals each in farms in the village of Mirkovo (715 m above sea level) with Sofia (Elinpelin) sheep breed and in the village of Gubesh (1040 m above sea level) with Central Balkan sheep breed. Body condition assessment was performed during sampling by one individual using an adapted system. Fresh faeces (total sample) were also collected for parasitological tests (coproovoscopy and coprolarvoscopy). Analysis of biochemical parameters was performed in extracted blood plasma with a BTS-350 semi-automatic biochemical analyzer. AST and glucose levels were normal, ALP and Fe were lower in both seasons, and ALT was higher than reference values limits only in summer for both breeds. There were significant differences between the two breeds in summer for BCS, ALT and glucose (p&lt;0.001, p&lt;0.05 and p&lt;0.01 respectively), in winter - only for Fe (p&lt;0.001) and in both seasons for HCT (p&lt;0.001 and p&lt;0.01 respectively), AST (p&lt;0.001 and p&lt;0.05 respectively) and ALP (p&lt;0.001 each). Regarding the activity of AST, there are no significant differences between the two seasons and in both breeds, however, there are such differences only in Central Balkan sheep for BCS and Fe (respectively p&lt;0.01 and p&lt;0.001), and in both breeds together with different degrees of freedom - for all other indicators (HCT, ALT, ALP and glucose).

Effect of a combination of rhinoplasty and septoplasty on the development of acute postoperative syndrome and cortisol secretion into blood plasma

Purpose of the study: to evaluate the effect of a combination of rhinoplasty and septoplasty on the development of acute postoperative syndrome and the secretion of cortisol into the blood plasma.Material and methods. A study was conducted in a group of 98 patients who underwent septoplasty, rhinoplasty or rhinoseptoplasty. Using a Digital Rating Scale, the intensity of pain was assessed 3, 6, 24, 48 hours after the end of surgery. The day before, immediately before and 6 hours after surgical interventions, all patients underwent blood sampling to determine the concentration of cortisol in the blood plasma. The data obtained were compared within groups over time, as well as between groups at the corresponding assessment points.Results. The intensity of pain 3 hours after surgery was significantly lower in the group of patients after rhinoplasty and significantly decreased after 6 (p &lt; 0.001), 24 (p &lt; 0.01), 48 (p &lt; 0.001) hours after surgery, compared with patients who underwent septoplasty and rhinoseptoplasty. In the early postoperative period, patients from the rhinoplasty group had the lowest cortisol concentrations in the blood plasma, compared with patients after septoplasty (p &lt; 0.001) and rhinoseptoplasty (p &lt; 0.01). In patients who underwent rhinoseptoplasty, the level of cortisol in the blood was significantly higher compared with patients after septoplasty (p &lt; 0.01).Conclusion. The assessment of acute pain using a digital rating scale after rhinosurgical interventions showed that septoplasty provokes the development of a stronger acute pain syndrome in the early postoperative period, which proves its trauma compared to rhinoplasty. Simultaneous rhinoplasty and septoplasty in the first days after surgery contributes to an increase in the concentration of cortisol in blood plasma, as well as an increase in pain syndrome.

The effect of inflammatory cytokines on occurrence of retained placenta in cattle

Background: In simple terms, retained placenta is a common issue after parturition in cattle that can affect their reproductive ability. In pregnancies with fetal growth restriction (FGR), the placenta has low anti-inflammatory cytokines and high pro-inflammatory cytokines. By looking at variations in cytokine levels in the blood, we can diagnose the condition. The focus of a recent study was to examine the role of some interleukins (Interleukins -10, Interleukins -6, Interleukins -1β), C-reactive protein (CRP) and Tumor Necrosis Factor (TNF)-α, in retained placenta occurrence in cattle.Methods: The study involved 40 cows, aged 3-8 years in the Salah-Din province. Each animal suffered from retained placenta also eleven healthy cows served as the control group in a period of January to August 2022. The blood serum was analyzed using enzyme immunoassay techniques (ELIZA) to measure the levels of IL-10, IL-6, IL-1β, CRP and TNF-α.Results: Serum levels of IL-10, IL-6, IL-1β, CRP and TNF-α showed a significant increase in cows experiencing retained fetal membranes compared to healthy cows (2.31±0.11 vs 1.41 ±0.07) (10.48±0.24 vs 5.40±0.19), (13.6±2.1 vs 4±0.9), (0.9±0.02 vs 0.32±0.04) and (60.1 ± 12.79 vs 29.5 ± 16.58) respectively.Conclusion: from the present study we conclude that IL10, IL6, IL1β and TNFα play an essential component in retained placenta incidence, and the estimation levels of these parameters in serum may be considered good indicator for occurrence in cattle. RT-PCR revealed increased expression of SDHA genes in the maternal compartment of the placenta.Keywords: Retained placenta; Cytokines; C-reactive protein

Lipid peroxidation-induced ferroptosis as a therapeutic target for mitigating neuronal injury and inflammation in sepsis-associated encephalopathy: insights into the hippocampal PEBP-1/15-LOX/GPX4 pathway

BackgroundSepsis-associated encephalopathy (SAE) refers to the widespread impairment of brain function caused by noncentral nervous system infection mediated by sepsis. Lipid peroxidation-induced ferroptosis contributes to the occurrence and course of SAE. This study aimed to investigate the relationship between neuronal injury and lipid peroxidation-induced ferroptosis in SAE.MethodsBaseline data were collected from pediatric patients upon admission, and the expression levels of various markers related to lipid peroxidation and ferroptosis were monitored in the serum and peripheral blood mononuclear cells (PBMCs) of patients with SAE as well as SAE model mice. The hippocampal phosphatidylethanolamine-binding protein (PEBP)-1/15-lysine oxidase (LOX)/ glutathione peroxidase 4 (GPX4) pathway was assessed for its role on the inhibitory effect of ferroptosis in SAE treatment.ResultsThe results showed elevated levels of S100 calcium-binding protein beta (S-100β), glial fibrillary acidic protein, and malondialdehyde in the serum of SAE patients, while superoxide dismutase levels were reduced. Furthermore, analysis of PBMCs revealed increased transcription levels of PEBP1, LOX, and long-chain fatty acyl-CoA synthetase family member 4 (ACSL4) in SAE patients, while the transcription levels of GPX4 and cystine/glutamate transporter xCT (SLC7A11) were decreased. In comparison to the control group, the SAE mice exhibited increased expression of S-100β and neuron-specific enolase (NSE) in the hippocampus, whereas the expression of S-100β and NSE were reduced in deferoxamine (DFO) mice. Additionally, iron accumulation was observed in the hippocampus of SAE mice, while the iron ion levels were reduced in the DFO mice. Inhibition of ferroptosis alleviated the mitochondrial damage (as assessed by transmission electron microscopy, hippocampal mitochondrial ATP detection, and the JC-1 polymer-to-monomer ratio in the hippocampus) and the oxidative stress response induced by SAE as well as attenuated neuroinflammatory reactions. Further investigations revealed that the mechanism underlying the inhibitory effect of ferroptosis in SAE treatment is associated with the hippocampal PEBP-1/15-LOX/GPX4 pathway.ConclusionThese results offer potential therapeutic targets for the management of neuronal injury in SAE and valuable insights into the potential mechanisms of ferroptosis in neurological disorders.

Effects of different preparation protocols of blood serum eyedrops on corneal healing after alkali burn: Clinical evaluation and α-SMA expression

Background: In cases of alkali burn, blood serum eyedrops may supply protein and growth factors. A standard preparation protocol is necessary for consistency in epitheliotropic capacity. Objective: We aim to evaluate how post-alkali-burn administration of blood serum eyedrops from different preparation protocols results in different outcomes on rabbits. Methods: This randomized experimental study used three treatments: placebo, non-diluted serum, and 25% concentration serum. We analyzed the corneal haziness, neovascularization degree, histopathological examination of neovascularization scores, and alpha-smooth muscle actin (α-SMA) expression. Results: Twelve rabbits (24 eyes) were split evenly into three treatment groups. On day 14, the group receiving the 25% concentration serum had the least corneal haziness (p = 0.005). No adverse effect was observed on the treated eyes. Histopathologically, no significant difference in neovascularization scores and α-SMA expression was observed. Conclusions: Treatment using the 25% concentration serum resulted in less corneal haziness, smaller defect size, and greater healing rate. There was also no significant difference in histopathological outcomes among the three treatment groups.

NMR-based metabolomic analysis of plasma from elderly patients with CVD before and after using contrast media

Contrast-induced acute kidney injury (CI-AKI) is a growingly common kidney problem caused by medical procedures involving contrast media (CM), especially in older patients with existing health issues. It is crucial to pinpoint potential biomarkers for the early detection of CI-AKI. Previously, we observed that iodixanol affects glucose, choline, and glutathione metabolism in endothelial cells under laboratory conditions. In this study, we used 1H NMR-based metabolomics to examine the metabolic changes in the blood plasma of elderly patients with cardiovascular disease (CVD) before and after receiving iodixanol. We identified altered metabolites in plasma 24 and 48 h after iodixanol injection compared to levels before injection. Notably, metabolites such as glucose, unsaturated fatty acids (UFA), low-density lipoprotein (LDL)/very low-density lipoprotein (VLDL), pyruvate, choline, and glycine showed potential as biomarkers at 24 h post-injection compared to levels before injection. Similarly, glucose, pyruvate, lactate, choline, and glycine in plasma could serve as potential biomarkers at 48 h post-injection. Iodixanol notably affected pathways related to glycolysis, fatty acid breakdown, and amino acid metabolism according to our metabolic pathway analysis. The altered levels of specific metabolites in plasma could be indicative of CM-induced kidney injury. Overall, this research aids in understanding the physiological mechanisms involved and in identifying early biomarkers and prevention strategies for CI-AKI.

Seroprevalencija virusa mačje leukemije i mačje imunodeficijencije u kućnih mačaka iz Pereire, Risaralda, Kolumbija

In Colombia, the increase in the population of domestic cats is directly related to outbreak diseases and associated with risks to domestic and wild animal health. Feline leukaemia virus (FeLV) and feline immunodeficiency virus (FIV) are two retroviral agents representing the most significant cause of feline morbimortality. Since they can be easily transmitted between cats through body fluids, these viruses can cause neoplastic and non-neoplastic alterations, immunosuppression, non-specific chronic diseases, and infections by opportunistic microorganisms. In order to improve animal health status and prevent these diseases from spreading, a timely and reliable diagnosis is necessary to detect these infectious agents. However, due to factors such as the distribution, size, mobility, and growth of the population of domestic felines, the prevalence and possible risk factors associated with the presentation of these viruses are currently unknown. This research was a descriptive cross-sectional study in which 100 domestic felines were sampled. The simultaneous diagnosis of the viruses was performed using whole blood samples for feline leukaemia and blood plasma for feline immunodeficiency and analysed by the Uranotest FeLV-FIV immunochromatographic dual method. The presence of infectious agents was correlated with study variables such as gender, age, origin, and feline habits. A prevalence of 14% for FIV and only 6% for FeLV was observed, with a 2% incidence of coinfection. Correlations were observed between infection and the age of the animals and their place of origin. The results allow us to know the current state of the spread of these infectious agents, which is essential for making decisions about animal health departmental prevention plans.

Multiplexed Opto-Microfluidic Biosensing: Advanced Platform for Prostate Cancer Detection.

Cancer stands as a prominent global cause of mortality, necessitating early detection to augment survival rates and alleviate economic burdens on healthcare systems. In particular, prostate cancer (PCa), impacting 1.41 million men globally in 2020, accentuates the demand for sensitive and cost-effective detection methods beyond traditional prostate-specific antigen (PSA) testing. While clinical techniques exhibit limitations, biosensors emerge as compact, user-friendly alternatives to traditional laboratory approaches. However, existing biosensors predominantly concentrate on PSA detection, prompting the necessity for advancing toward multiplex sensing platforms. This study introduces a compact opto-microfluidic sensor featuring a substrate of gold nanospikes, fabricated via electrodeposition, for enhanced sensitivity. Embedded within a microfluidic chip, this nanomaterial enables the precise and concurrent measurement of PSA, alongside two complementary PCa biomarkers, matrix metalloproteinase-2 (MMP-2) and anti-α-methylacyl-CoA racemase (anti-AMACR) in diluted human plasma, offering a comprehensive approach to PSA analysis. Taking advantage of the localized surface plasmon resonance principle, this biosensor offers robustness and sensitivity in real sample analysis without the need for labeling agents. With the limit of detection at 0.22, 0.37, and 0.18 ng/mL for PSA, MMP-2, and anti-AMACR, respectively, this biosensing platform holds promise for point-of-care analysis, underscoring its potential impact on medical diagnostics.

In vitro and in vivo metabolism of psilocybin's active metabolite psilocin.

In vivo, psilocybin is rapidly dephosphorylated to psilocin which induces psychedelic effects by interacting with the 5-HT2A receptor. Psilocin primarily undergoes glucuronidation or conversion to 4-hydroxyindole-3-acetic acid (4-HIAA). Herein, we investigated psilocybin's metabolic pathways in vitro and in vivo, conducting a thorough analysis of the enzymes involved. Metabolism studies were performed using human liver microsomes (HLM), cytochrome P450 (CYP) enzymes, monoamine oxidase (MAO), and UDP-glucuronosyltransferase (UGT). In vivo, metabolism was examined using male C57BL/6J mice and human plasma samples. Approximately 29% of psilocin was metabolized by HLM, while recombinant CYP2D6 and CYP3A4 enzymes metabolized nearly 100% and 40% of psilocin, respectively. Notably, 4-HIAA and 4-hydroxytryptophol (4-HTP) were detected with HLM but not with recombinant CYPs. MAO-A transformed psilocin into minimal amounts of 4-HIAA and 4-HTP. 4-HTP was only present in vitro. Neither 4-HIAA nor 4-HTP showed relevant interactions at assessed 5-HT receptors. In contrast to in vivo data, UGT1A10 did not extensively metabolize psilocin in vitro. Furthermore, two putative metabolites were observed. N-methyl-4-hydroxytryptamine (norpsilocin) was identified in vitro (CYP2D6) and in mice, while an oxidized metabolite was detected in vitro (CYP2D6) and in humans. However, the CYP2D6 genotype did not influence psilocin plasma concentrations in the investigated study population. In conclusion, MAO-A, CYP2D6, and CYP3A4 are involved in psilocin's metabolism. The discovery of putative norpsilocin in mice and oxidized psilocin in humans further unravels psilocin's metabolism. Despite limitations in replicating phase II metabolism in vitro, these findings hold significance for studying drug-drug interactions and advancing research on psilocybin as a therapeutic agent.

Occupational lung diseases from exposure to industrial fibrogenic aerosols of varying degrees of fibrogenicity: occupational risk assessment, features of immunopathogenesis, prediction

The purpose of the study is to assess occupational risk and study the characteristics of immunopathogenesis in occupational lung diseases from exposure to industrial aerosols. Material and research methods. The study included 304 people with over 10 years of work experience under conditions of exposure to high concentrations of industrial fi brogenic aerosols (above the permissible concentration), who underwent an in-depth periodic medical examination at the regional center of occupational pathology Samara City Hospital No. 5 with an assessment of the relative risk (RR), its etiologic fraction (EF), and odds ratio (OR) of the development of occupational respiratory diseases. The comparison group included 120 people. To assess the cytokine profile indices in occupational lung diseases (various degrees of severity of dust-induced occupational diseases, silicosis, and pneumoconiosis from exposure to highly dispersed welding aerosols), 161 people with occupational lung diseases and 60 people in the control group were examined. Levels of immunoglobulins A, M, and G in blood serum, hemolytic activity of complement, and the level of myeloperoxidase were determined using standard reactions. Determination of the levels of total IgE, fibronectin, cytokines IL-1α, IL-1β, IL-4, IL-8, IFNγ, and TNFα, growth factors FGF-2, VEGF in blood serum was carried out by enzyme -linked immunosorbent assay. Results. The occupational risk of developing dust lung diseases from exposure to various types of fibrogenic industrial aerosols, as well as the features of the course of occupational lung diseases have been determined. The identified features of the immu nological profile allow establishing the features of the occurrence, course, and progres sion of occupational lung diseases and recommending changes to the National List of Occupational Diseases. Conclusions. Determining occupational risk and immunological profile allows not only improving the quality of early diagnosis, but optimizing primary and secondary prevention strategies for this pathology, predicting the course of the disease, and reducing the number of disabling forms.

The Correlation between Ultrasonographic Morphology and Structure of the Left Atrial Appendage, Blood Flow Velocity, and Plasma Galectin-3 Levels with Thrombus Formation in the Left Atrial Appendage of Patients with Atrial Fibrillation

Background: To explore the correlation between left atrial appendage morphology, blood flow velocity and plasma galectin-3 and thrombosis in patients with atrial fibrillation. Methods: Patients with atrial fibrillation who received treatment and completed ultrasound examination in hospital from 2022 to December 2023 were enrolled. According to whether there was left atrial appendage thrombosis, the patients were divided into a control group (no left atrial appendage thrombosis was found) and a study group (left atrial appendage thrombosis was found). The morphology and structure of the left atrial appendage, blood flow velocity and plasma galectin-3 level were recorded，exploring its correlation with left atrium thrombosis. Results: A total of 330 patients with atrial fibrillation were enrolled, including 278 in the control group and 52 in the study group. Left group and the control group of morphological structure differences (P &lt; 0.05). The main lobe length, ostial area, longest diameter, shortest diameter, left atrial appendage volume and left atrial volume in the study group were higher than those in the control group (P &lt; 0.05). The left atrial appendage emptying velocity, filling velocity and left ventricular ejection fraction of the study group were lower than those of the control group, and the left ventricular end-diastolic diameter was higher than that of the control group (P &lt; 0.05). Group of white blood cell count, neutrophils/lymphocyte ratio, plasma galactose lectin - 3 levels were higher than control group (P &lt; 0.05). ROC curve analysis of left atrial appendage emptying velocity, left atrial appendage filling velocity, left atrial end-diastolic diameter and left atrial ejection fraction had higher diagnostic value (P &lt; 0.05). Conclusion: Left atrial appendage morphology, blood flow velocity and plasma galectin-3 level are important factors to evaluate the risk of left atrial appendage thrombosis in patients with atrial fibrillation, which can be used for clinical diagnosis and decision-making.

Frequency of hypoglycaemia with basal insulin treatments in adults with type 1 diabetes treated with basal-bolus insulin regimens in treat-to-target trials: A narrative review.

To summarise, in a narrative review, published data on hypoglycaemia occurrence with basal insulin therapy in adults with type 1 diabetes treated with basal-bolus insulin regimens in treat-to-target randomised controlled trials. Data were included from 21 eligible trials, which mainly used self-measured blood glucose or plasma glucose to detect hypoglycaemia. All-day self-measured blood glucose or plasma glucose level 2 (glucose threshold of 3.1 or 3.0 mmol/L) and level 3 (severe, requiring assistance) hypoglycaemic events were reported, respectively, by a range of 69.0%-97.5% and 0%-13.4% adults when receiving basal-bolus insulin therapy, with rates of 10.6-68.1 and 0.0-0.4 events per patient-year of exposure, respectively. Hypoglycaemia rates measured using continuous glucose monitoring (three studies) were numerically, yet consistently, higher than with either other method, except when limiting to symptomatic events. Nocturnal hypoglycaemia rates were generally less than 30% of the equivalent all-day rates. Differences across the studies in design (e.g., titration targets) and participant characteristics hindered comparison of hypoglycaemia rates by insulin formulation. Consequently, few trends were identified by insulin formulation, study methodology or individuals' characteristics, suggesting that further research is required to identify treatment strategies that facilitate development of individualised recommendations to lower hypoglycaemia risk. These findings are useful to understand hypoglycaemia risk with available basal insulin therapies when used in a multiple daily injection regimen, as well as to provide context for the results of ongoing and future clinical trials, including those for two once-weekly basal insulins, insulin icodec and basal insulin Fc.

Relationship between the outcomes of intensive phase therapy in patients with newly diagnosed infiltrative pulmonary tuberculosis and activity of purine metabolism enzymes as well as CD3+CD8+ lymphocyte level

Monitoring activity of inflammatory process and lymphocyte subsets can help assess the effectiveness of intensive phase therapy (IPT) already in the early stages of treatment. The goal is to evaluate changes in the concentration and activity of enzymes associated with purine metabolism and peripheral blood lymphocyte subset composition, and to determine their relationship with IPT effectiveness in patients with newly diagnosed infiltrative pulmonary tuberculosis (IPTb). Materials and methods. In 141 IPTb patients, the IPT data were presented as follows: “significant improvement” (SI) — disappearance of intoxication symptoms, abacillation, closure of decay cavities; “less pronounced improvement” (LMI) — eliminated symptoms of intoxication, abacillation, pronounced resorption of focal and infiltrative changes, reduction of decay cavities. We assessed the activity of adenosine deaminase in blood serum (eADA-1, 2), mononuclear cells and neutrophils, the concentration of blood serum ecto-5'-nucleotidase (eHT5E), CD26 (DPPV) in blood serum (s, soluble form) and mononuclear cells (m, membrane form), subpopulation composition. Results. Patients exhibit increased concentrations of eNT5E, mCD26 (DPPIV) and eADA-2 activity, and decreased intracellular ADA-1 activity. In the “LMI” group, after IPT, an increased sCD26 (DPPV) level was noted. The groups differed in lymphocyte counts and percentage of CD3+CD8+ cells. eADA-2 activity was higher in the LMI group and increased after IPT, in contrast to comparison group. mCD26 (DPPIV) concentrations are higher in PD patients before therapy and after IPT. Conclusion. Thus, the outcome of IPT in IPTb patients is associated with altered T-lymphocyte populations and severity of the inflammatory process. Studying the activity of membrane and soluble eADA-2, CD26 (DPPIV) and percentage of CD3+CD8+ T-lymphocytes in the early stages of therapy can provide the necessary information for correcting personalized pathogenetic therapy of patients with newly diagnosed IPTb.
