Immunological, Antioxidant, Growth Responses, and Disease Resistance of Rainbow Trout, Oncorhynchus mykiss, with Feeding Diets Supplemented with Lactobacillus salivarius and Lutein

Abstract The aim of the present study was to assess the effects of dietary supplementation with Lactobacillus salivarius (LS) ATCC 11741 and lutein (LU) on immunological, antioxidant, and growth responses, and resistance against Yersinia ruckeri infection in rainbow trout (Oncorhynchus mykiss). There were seven experimental diets containing un-supplemented diet (CTL), L. salivarius at 1 × 106 (LS6) and 1 × 108 (LS8) CFU/g, lutein at 50 (LU50) and 150 (LU150) mg/kg, L. salivarius at 1 × 106 CFU/g plus lutein at 50 g/kg (LS6+LU50), and L. salivarius at 1 × 108 CFU/g plus lutein at 150 g/kg (LS8+LU150). These diets were provided to the fish (N= 735; 14.0±0.38 g). After 60 days of feeding, all experimental treatments exhibited significantly higher growth performance, compared to the CTL treatment. The intestinal protease activity and the intestinal lactic acid bacteria population in the probiotic-treated fish were significantly higher than in the CTL fish. The intestinal lipase activity was only higher in the LS6+LU50 treatment, compared to the CTL treatment. Compared to the CTL treatment, the intestinal total bacterial count, and serum superoxide dismutase significantly increased in the LS6+LU50 and LS8+LU150 treatments. The serum catalase significantly increased in LU150, LS6+LU50, and LS8+LU150 treatments, and serum glutathione peroxidase significantly increased in the lutein-treated fish. All experimental treatments, particularly LS6+LU50 and LS8+LU150, had significantly lower serum malondialdehyde levels, compared to the CTL treatment. The levels of serum alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, and lactate dehydrogenase in LU50, LS6+LU50, and LS8+LU150 treatments were significantly lower than the CTL. All experimental treatments showed significantly higher serum lysozyme (LYZ), complement, blood respiratory burst activity (RB), and skin mucus alkaline phosphatase (ALP), compared to the CTL treatment. The highest serum LYZ, C4, total immunoglobulin (Ig), blood RB activity, and skin mucus peroxidase, ALP, and Ig were observed in the LS6+LU50 and LS8+LU150 treatments. All the experimental treatments, especially LS6+LU50, exhibited significantly lower mortality after the bacterial challenge compared to the CTL. In conclusion, dietary supplementation with 1 × 106 CFU/g L. salivarius and 50 mg/kg lutein can maximally improve growth performance, digestive enzymes, antioxidant parameters, immune responses, intestinal lactic acid bacteria, and resistance against yersiniosis in rainbow trout.

Effects of water immersion on immune, intestinal flora and metabolome of Chinese mitten crab (Eriocheir sinensis) after air exposure

Air exposure stress can induce stress response of Eriocheir sinensis and affect its normal life activities. The goal of this study was to investigate the effects of water immersion on the recovery of hepatopancreas immune-related enzyme activity, intestinal microbial diversity and metabolic level of Chinese mitten crabs after exposure to air. The results show that immersion can effectively alleviate the adverse effects of air exposure on the antioxidant capacity and immune capacity of Chinese mitten crabs, and the longer the time of immersion, the more obvious the recovery effect. Among them, the levels of aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase and acid phosphatase significantly increased after exposure to air (P < 0.05), reached a peak at 3 h, began to decline after immersion, and returned to a level close to the initial value at 24 h (P < 0.05). In addition, after exposure to air, the glucose and total cholesterol in haemolymph of Eriocheir sinensis were significantly different from the initial values (P < 0.05), gradually recovered to the initial level after re-immersion. However, changes in intestinal flora and hepatopancreas metabolism caused by air exposure did not fully recover after water exposure, and its negative effects did not completely disappear. The sequencing results showed that the species composition and diversity of intestinal microorganisms of Chinese mitten crab changed after air exposure and immersion treatment. The relative abundance of Actinomycetes increased significantly, while that of Proteobacteria and Firmicutes decreased significantly. Metabolomics analysis showed that air exposure and immersion destroyed the metabolic balance of amino acids and carnitine, reduced the level of carnitine metabolism, hindered the absorption of nutrients, and led to the accumulation of harmful substances.

A Comprehensive Analysis Exploring the Vital Role of the Systemic Immune-Inflammatory Index Upon Admission in Severe Hemorrhagic Fever with Renal Syndrome.

To explore the value of the systemic immune-inflammatory index (SII) and the systemic inflammatory response index (SIRI) in patients with severe hemorrhagic fever with renal syndrome (HFRS) upon admission. This study included a total of 165 patients with HFRS, who were divided into mild and severe groups based on the severity of the disease. By reviewing medical records, we collected the white blood cell (WBC), SII, and SIRI values of patients upon admission. Univariate and multivariate logistics regression analyses were performed to identify risk factors for severe HFRS. The receiver operating characteristic (ROC) curve was applied to calculate the area under the ROC curve (AUC) to analyze the predictive value of SII and SIRI for severe HFRS, and the results were compared with WBC and SIRI. Compared with the mild HFRS group, patients in the severe HFRS group had a longer duration of illness (P < 0.05), higher levels of WBC, neutrophil (NEUT), lymphocyte (LYMP), monocyte (MONO), procalcitonin (PCT), SIRI, alanine transaminase (ALT), and creatinine (Scr) (P < 0.05), while lower levels of ALB, platelet (PLT), platelet-to-lymphocyte rate (PLR), and SII, with statistically significant differences (P < 0.05). Binary logistics regression analysis indicated that WBC (OR: 1.190, 95% CI: 1.032-1.371), SII (OR: 0.967, 95% CI: 0.951-0.984), and SIRI (OR: 4.743, 95% CI: 2.077-10.830) were risk factors for severe HFRS. The AUCs of WBC, SII, and SIRI for predicting severe HFRS were 0.765, 0.803, and 0.785, respectively. Low levels of SII and high levels of WBC and SIRI upon admission are risk factors for severe HFRS and have certain value in predicting the progression of HFRS to severe cases, among which SII exhibits the best predictive value.

Unveiling Resmetirom: A systematic review and meta-analysis on its impact on liver function and safety in non-alcoholic steatohepatitis treatment.

The role of Resmetirom in non-alcoholic steatohepatitis (NASH) represents a promising therapeutic approach in addressing the growing global burden of liver disease. With NASH emerging as a leading cause of liver-related morbidity and mortality worldwide, there is an urgent need for effective treatments. Resmetirom, a selective thyroid hormone receptor-β agonist, offers potential benefits in improving liver histology and metabolic parameters in patients with NASH. This review examines the current evidence surrounding Resmetirom's role in NASH management. A systematic review and meta-analysis was done by searching in Cochrane Central Register of Controlled Trials (CENTRAL), PubMed, MEDLINE (including MEDLINE InProcess) (OvidSP), Web of Science, Embase (OvidSP), and Scopus databases. ROB2 Cochrane tool was used for assessing risk of bias in randomized controlled trials (RCTs). In the analysis, we used RevMan Cochrane software. The study showed that patients who were treated with Resmetirom had significantly lower low-density lipoprotein-cholesterol (LDL-C) levels (mean difference [MD] -10.45; 95% confidence interval [CI] -15.86 to -5.83; P < 0.001) and alanine aminotransferase (ALT) levels (MD -7.18; 95% CI -12.67 to -1.68; P = 0.01) as compared with those in the placebo group. The risk of adverse events including diarrhea [risk ratio (RR)1.81; 95% CI 1.40 to 2.35; P < 0.001] and nausea (RR 1.72; 95% CI 1.31 to 2.27; P < 0.001) was significantly increased for the Resmetirom group as compared with the placebo group. Resmetirom presents a promising therapeutic option for NASH, offering potential benefits in reducing liver fat content and improving histological outcomes. The encouraging results from clinical trials suggest that Resmetirom may address an unmet need in NASH management, providing hope for patients with this progressive liver disease. Further research and long-term studies are warranted to validate its efficacy and safety profile in larger patient populations.

Effects of Korean red ginseng on auditory, cognitive, and liver functions in a naturally aged mouse model

BackgroundKorean Red Ginseng and ginsenosides have been studied for their efficacy against various diseases, including those related to aging. However, most aging studies use D-galactose to induce aging, which often does not accurately represent natural aging. This study aimed to verify improvements in auditory, cognitive, and liver function through administering red ginseng to an 18-month-old naturally aging mouse model. MethodsAuditory function was assessed using Auditory Brainstem Response (ABR) and Auditory Middle Latency Response (AMLR). Cognitive function was evaluated electrophysiologically with P300 and mismatch negativity (MMN), and behaviorally using the Y-maze. Additionally, biochemical tests and histological analysis were conducted to assess liver function. The effects of red ginseng on gene expression regulation were also examined in the cochlea, auditory cortex, and liver, focusing on age-related disease processes. ResultsRed ginseng significantly decreased hearing thresholds and improved central auditory function. It also enhanced cognitive behavior and function in response to external stimulation. Furthermore, red ginseng regulated alkaline phosphatase (ALP), albumin (Alb), and total protein (TP) levels, notably decreasing aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels. Hematoxylin and eosin (H&E) staining of liver tissue showed significant improvement in fat droplets. These effects appear to be mediated by the regulation of aging-related genes Dec, c-Jun, Stat5b, and Lims2. ConclusionThese results suggest that red ginseng improves auditory, cognitive, and liver functions in a naturally aged mouse model.

Are Systemic Inflammation Markers Reliable for Diagnosing Intrahepatic Cholestasis of Pregnancy? A Retrospective Cohort Study.

This study aims to evaluate the effectiveness of inflammation indexes (systemic immune-inflammation index [SII], systemic inflammation response index [SIRI], pan-immune inflammation value [PIV], and neutrophil-to-lymphocyte ratio [NLR]) in the diagnosis of intrahepatic cholestasis of pregnancy (ICP). A retrospective study was conducted, reviewing medical records of patients diagnosed with ICP who delivered between October 1, 2022, and May 31, 2023, at the Perinatology clinic of Etlik City Hospital, Ankara. A control group of healthy pregnant women with uncomplicated pregnancies was also included. Demographic data, clinical characteristics, and laboratory results, including systemic inflammation indices and liver enzyme levels, were collected and analyzed. A total of 242 participants were included, with 121 ICP patients and 121 controls. White blood cell count, neutrophil count, and monocyte count showed significant differences between the two groups (p = 0.011, p = 0.004, and p = 0.039, respectively). Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels were significantly elevated in the ICP group (p < 0.001 for both). SII and NLR were higher in the ICP group compared to controls (p = 0.032 and p = 0.010, respectively). Receiver operating characteristic (ROC) analysis revealed moderate predictive values for SII (area under the curve [AUC] = 0.581, p = 0.030) and NLR (AUC = 0.598, p = 0.009), with no significant difference in their predictive power (p = 0.502). Systemic inflammation indices such as SII and NLR offer a cost-effective and rapid means of diagnosing ICP, potentially complementing or surpassing traditional biomarkers like bile acid levels and liver function tests (LFTs). These indices can be easily integrated into routine clinical practice, providing timely intervention to improve maternal and fetal outcomes. Further research is warranted to confirm these findings and establish standardized protocols for their use in ICP management.

Effects of including different levels of equal mix of soybean and flaxseed oils in Japanese quail diets on the growth, carcass quality, and blood biomarkers

Corn, the primary ingredient in modern poultry feeds, contains high levels of ω-6 fatty acids but lacks sufficient ω-3 fatty acids, creating an imbalance. Maintaining a balance between ω-6 and ω-3 fatty acids in poultry diets is crucial due to their competition. This study aimed to evaluate the effects of incorporating different concentrations of an equal mix of soybean oil (SO) and flaxseed oil (FO) into quail diets on growth performance, carcass quality, and blood biochemistry. One-week-old Japanese quail birds (n=200) were randomly assigned to four dietary groups, each comprising five replicates with 10 chicks per replicate. Four isonitrogenous/isocaloric basal diets were formulated. Group 1 (control) received a basal diet without SO or FO, while Groups 2-4 received basal diets supplemented with an equal mix of SO+FO at levels of 1.0%, 1.5%, and 2.0%, respectively. The inclusion of oil mixes significantly increased body weight (BW) at five weeks and daily weight gain (DWG) during weeks 3-5 and 1-5. The feed conversion ratio (FCR) improved with the addition of oil mixes throughout the trial period. Supplementing quail diets with oil mixes resulted in reduced serum total cholesterol (TC) and LDL cholesterol, elevated serum HDL cholesterol, and no significant effect on triglycerides (TG) and VLDL cholesterol levels. Quails fed oil-supplemented diets showed lower serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), and creatinine levels, while urea and uric acid were significantly affected. Birds fed diets with oil mixes also had increased serum concentrations of immunoglobulin G (IgY), immunoglobulin M (IgM), and superoxide dismutase (SOD). However, serum immunoglobulin A (IgA), malondialdehyde (MDA), and total antioxidant capacity (TAC) levels did not significantly change across experimental groups. Overall, adding up to 2% of the SO and FO mix in growing quail feeds improved growth performance, blood lipid profile, liver and kidney function markers, immune response, and antioxidant defense. The highest level of oil mix (2%) yielded the most beneficial effects.

Effect of CYP3A5*3 genotype on exposure and efficacy of quetiapine: A retrospective, cohort study

BackgroundThe involvement of cytochrome P450 3A5 (CYP3A5) in the metabolism of quetiapine has been proposed, though conclusive evidence is lacking. This study aimed to quantitatively assess the impact of CYP3A5 genetic variability on quetiapine exposure in a Chinese patient population. MethodsPatient data were retrospectively collected from the database of the Mental Health Centre at the First Hospital of Hebei Medical University, covering the period from September 1, 2019, to July 1, 2023. The study included patients genotyped for CYP3A5 who were treated with quetiapine. Inclusion criteria for the analysis of pharmacokinetic parameters, such as serum concentrations of the drug and its metabolites, included oral administration of quetiapine, availability of information on the prescribed daily dose and concomitant medications, and the determination of steady-state blood levels at the time of sampling (after at least 3 days of continuous administration at the same dose). Exclusion criteria comprised polypharmacy with known CYP3A4 inducers or inhibitors, as well as patients with hepatic or renal insufficiency. The primary endpoint was the exposure to quetiapine and N-dealkylquetiapine, measured using dose-corrected concentrations (C/D). The secondary endpoint was the metabolism of quetiapine to N-dealkylquetiapine, assessed by the ratio of metabolite to parent drug concentrations. The third endpoint is the differences in adverse reactions, QTc intervals, and biochemical parameters among patients with different CYP3A5 genotypes. ResultBased on the inclusion and exclusion criteria, clinical data from 207 patients were ultimately included in the study. Of these, 20 patients had the CYP3A5*1/*1 genotype, 78 had the CYP3A5*1/*3 genotype, and 109 had the CYP3A5*3/*3 genotype.The CYP3A5*3 variant was found to significantly impact the metabolism of quetiapine. The C/D values for both quetiapine and dealkylated quetiapine were notably higher in individuals with the *3/*3 genotype compared to those with the *1/*1 and *1/*3 genotypes (P1 <0.001 and P2 = 0.002, respectively). A comparison of the variability in metabolic ratios among different genotype groups revealed no significant difference (P = 0.067). However, a post hoc analysis indicated that the metabolic ratio in poor metabolizers was significantly lower than that in intermediate metabolizers (P = 0.021). The analysis of adverse reaction incidence and QTc intervals among different genotypes showed no statistically significant differences (P = 0.652, P = 0.486). However, comparison of biochemical parameters across different genotype groups revealed that alanine aminotransferase, uric acid, hemoglobin, and gamma-glutamyl transferase levels were significantly higher in patients with the CYP3A5*3/*3 genotype compared to those with the CYP3A5*1/*1 and CYP3A5*1/*3 genotypes. ConclusionThe results indicated that the genetic polymorphism of CYP3A5*3 significantly influences the metabolism of quetiapine. Specifically, carriers of the CYP3A5*3/*3 genotype exhibited higher blood levels of quetiapine, with a greater likelihood of these levels exceeding the therapeutic range. This finding underscores the need for clinicians to carefully monitor and potentially adjust the dosage for patients with this genotype to avoid adverse effects. This finding underscores the need for clinicians to pay special attention to the efficacy and occurrence of adverse reactions when prescribing quetiapine to patients carrying the CYP3A5*3/*3 genotype.

Association of Monocyte Chemoattractant Protein-1 (MCP-1) 2518 A/G Polymorphism with Obesity in Korean Type 2 Diabetes Mellitus.

Monocyte chemoattractant protein-1 (MCP-1) is a member of the CC chemokine family, and the MCP-1 2518 A/G gene polymorphism is reported to be correlated with chronic inflammatory diseases, including insulin resistance and metabolic syndrome. However, few studies have investigated the association between MCP-1 gene polymorphisms and obesity in patients with type 2 diabetes mellitus (T2DM). We conducted a retrospective case-control study and evaluated the association between the MCP-1 2518 A/G polymorphism and obesity in Korean patients with T2DM. This single-center, retrospective, case-control study enrolled 526 Korean patients with T2DM. Obesity was defined using the body mass index (BMI) with a cutoff level of 25 kg/m2. Polymerase chain reaction-restriction fragment length polymorphism was used to analyze MCP-1 2518 A/G polymorphism; the genotypes was presented as GG, AG, or AA. We compared the MCP-1 2518 A/G polymorphism with the prevalence of diabetic complications, as well as clinical and biochemical characteristics. The obese group had a higher number of females and higher C-peptide, insulin, triglycerides, aspartate transaminase (AST), and alanine transaminase (ALT) levels. The obese group also had a higher prevalence of cardiovascular disease than the non-obese group. The obese group had a higher frequency of the MCP-1 2518 AA genotype and the A allele than the non-obese group. The results of multiple logistic regression analysis showed that the non-G allele of MCP-1 was significantly associated with obesity (odds ratio (OR), 1.888; P=0.016). This study demonstrates that the MCP-1 2518 A/G polymorphism is associated with obesity in Korean patients with T2DM. Further studies involving various ethnic groups are required to validate our results.

Unveiling Immunological and Hematological Markers in COVID-19: Insights from a Clinical Study.

The COVID-19 pandemic has affected the global health system and economies largely. Therefore, knowledge about the clinical and laboratory profiles of patients with COVID-19 would help in the management and prognosis of the disease. The immunological and hematological indices have emerged as critical determinants for the severity of the disease and the prognosis; however, association with COVID-19 is clouded. The present study is aimed to characterize the immunological and hematological profiles of patients with COVID-19 in correlation with the disease severity. The study included 1,019 polymerase chain reaction (PCR)-confirmed patients with COVID-19 who were classified into serious and nonserious groups, considering severity criteria. Clinical laboratory investigations included hematological, biochemical, and immunological parameters regarding leukocyte counts, hemoglobin levels, and inflammatory markers. Our analysis of immunological and hematological differences between serious and nonserious patients with COVID-19 indicates that serious cases reflected elevated levels of pro-inflammatory markers such as lactate dehydrogenase, C-reactive protein (CRP), D-dimer, and ferritin, representing immune system dysregulation and systemic inflammation. Furthermore, in serious cases, discrepancies had also been noticed for many hematological parameters than nonserious ones, which also contained leukocyte count and hemoglobin level. Additionally, the CRP, D-dimer, blood urea nitrogen, alanine transaminase, and albumin levels could be independent predictors of COVID-19 severity by multivariate logistic regression analysis. Cutoff values for these biomarkers were defined by receiver operating characteristic curve analysis defining optimal parameters for the risk stratification and prognostication. The current investigation provides a comprehensive understanding of immunological and hematological correlation with COVID-19 severity, refining clinical decision-making and therapeutic interventions to improve patient outcomes.

Diosgenin Alleviates Obesity-Induced Insulin Resistance by Modulating PI3K/Akt Signaling Pathway in Mice Fed a High-Fat Diet.

Obesity is a global medical issue that can be effectively treated by relieving adipose inflammation and subsequent insulin resistance. Diosgenin (DIOS) has various effects as a steroidal saponin in inflammatory disorders. This study explored the effects and mechanism of DIOS on adipose inflammation and insulin sensitivity, both in silico and in vivo. The high-fat diet-induced obesity model in C57BL/6 mice was divided into five groups: normal chow (NC), high-fat diet (HFD), HFD with atorvastatin 10 mg/kg (AT), HFD with DIOS 100 mg/kg (DIOS 100), and HFD with DIOS 200 mg/kg (DIOS 200). Each group underwent an oral intervention for seven weeks. DIOS significantly suppressed weight gain in the body, liver, and epididymal fat pads. Additionally, it significantly improved fasting glucose and insulin levels, homeostatic model assessment of insulin resistance (HOMA-IR), and oral glucose tolerance test results, and reduced the proportion of total and M1 adipose tissue macrophages. Significant changes were shown in mRNA expression of janus kinase 2 (JAK2), insulin receptor (INRS), insulin receptor substrate 1 (IRS-1), phosphatidylinositol 3-kinase (PI3K), and protein kinase B (Akt), all of which exhibited high binding affinity in the in silico. Safety indices, including aspartate aminotransferase (AST), alanine transaminase (ALT), and creatinine level indicated the preventive effects of DIOS. In conclusion, DIOS improves insulin resistance and obesity-associated inflammation via the PI3K/Akt signaling pathway.

Hepatocyte activation and liver injury following cerebral ischemia promote HMGB1-mediated hepcidin upregulation in hepatocytes and regulation of systemic iron levels

We previously reported that high mobility group box 1 (HMGB1), a danger-associated molecular pattern (DAMP), increases intracellular iron levels in the postischemic brain by upregulating hepcidin, a key regulator of iron homeostasis, triggering ferroptosis. Since hepatocytes are the primary cells that produce hepcidin and control systemic iron levels, we investigated whether cerebral ischemia induces hepcidin upregulation in hepatocytes. Following middle cerebral artery occlusion (MCAO) in a rodent model, significant liver injury was observed. This injury was evidenced by significantly elevated Eckhoff’s scores and increased serum levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST). Additionally, total iron levels were significantly elevated in the liver, with intracellular iron accumulation detected in hepatocytes. Hepcidin expression in the liver, which is primarily localized in hepatocytes, increased significantly starting at 3 h after MCAO and continued to increase rapidly, reaching a peak at 24 h. Interestingly, HMGB1 levels in the liver were also significantly elevated after MCAO, with the disulfide form of HMGB1 being the major subtype. In vitro experiments using AML12 hepatocytes showed that recombinant disulfide HMGB1 significantly upregulated hepcidin expression in a Toll-like receptor 4 (TLR4)- and RAGE-dependent manner. Furthermore, treatment with a ROS scavenger and a peptide HMGB1 antagonist revealed that both ROS generation and HMGB1 induction contributed to hepatocyte activation and liver damage following MCAO–reperfusion. In conclusion, this study revealed that cerebral ischemia triggers hepatocyte activation and liver injury. HMGB1 potently induces hepcidin not only in the brain but also in the liver, thereby influencing systemic iron homeostasis following ischemic stroke.

Association of perfluoroalkyl substances (PFAS) with liver function biomarkers in the highly exposed population of the veneto region

IntroductionEpidemiological studies highlight the presence of associations between per- and polyfluoroalkyl substances (PFAS) exposure with liver damage. In 2013, PFAS contamination was discovered in Veneto (Italy), leading to the implementation of a Surveillance Program (SP). Our objective is to investigate the association between PFAS exposure and biomarkers of liver function using single-pollutant and mixture approaches, while exploring the sex-specific differences and the mediating role of obesity in the association. MethodsThe study included 42,094 subjects aged ≥20 years participating in the SP. We used generalized additive models to investigate the association between several PFAS and alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels, adjusting for possible confounders and stratifying by sex. Results were back-transformed to show predicted percentage changes in outcomes per ln-unit increase in PFAS levels; furthermore, we explored the role of BMI in the abovementioned causal pathway, considering it as a potential confounder or mediator PFAS joint effect was investigated using Quantile G-computation. ResultsOne ln-unit increase in PFHxS concentrations was associated with a 1.49% (95%CI: 0.87, 2.12) and a 0.84% (95% CI: 0.27, 1.40) increase in ALT levels, in males and females respectively; one ln-unit increase in PFOA concentrations was associated with a 1.03% (95%CI: 0.50, 1.55) increase in ALT levels in males, and a 0.52% (95% CI: 0.22, 0.82) and a 0.60% (95% CI: 0.25, 0.96) increase in AST levels in females and males. PFOS showed no association with ALT and AST levels. Quantile G-computation revealed that an interquartile increase in the PFAS mixture was associated with a 3.02% increase (95% CI: 1.65, 4.43) and a 1.65% (95% CI: 0.77, 2.5) increase in ALT levels, in females and males. Mediation analysis suggested that BMI suppressed the association between PFAS and ALT levels, with positive direct effects higher than the total effects. ConclusionOur findings suggest sex-specific associations between PFAS exposure and liver function biomarkers and underscore the need for additional studies on potential mediators.

Protective Effect of Banana, Cassava, and Corn Flours on Hepatotoxicity of Malnourished Male Rats

Background: Malnutrition-induced hepatotoxicity is defined as liver damage caused by insufficient nutrition, which results in oxidative stress and damage to liver cells. Objectives: The present study aimed to investigate the protective effects of banana, cassava, and corn flours on hepatotoxicity induced by malnutrition in male rats. Methods: Twenty-four male rats were divided into six groups (n=4): (1) rats received 30 g/rat normal feed daily for 45 days; (2) rats received 30 g malnutrition feed daily for 45 days; rats received 30 g/rat malnutrition feed daily for 15 days and then treated with normal feed (3), banana flour (4), cassava flour (5), and corn flour (6), for 30 days. The malnutrition groups received a diet with protein deficiency for 15 days, then were treated with a diet according to each treatment group. The liver enzymes were analyzed, including aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels. Furthermore, the liver's histopathological changes in each group were evaluated using Hematoxylin eosin staining. Results: The AST levels in malnourished male rats significantly (p&lt;0.05) increased (240.75±67.23 U/L) compared to the control group (170.00±33.52 U/L). While, the ALT levels (66.75±12.69 U/L) were decreased compared to the control group (98.75±26.61 U/L). Furthermore, malnutrition diet in rats caused significant changes in liver histology, including inflammatory cell infiltration, necrosis, congestion of the central vein, cytoplasmic vacuolization, and widened hepatic sinusoid. Interestingly, normalized AST and ALT levels and improved liver histology were observed in malnourished rats after receiving normal feed and flour of banana, cassava, and corn. Conclusions: Banana, cassava, and corn flours exhibited hepatoprotective activity on malnutrition-induced hepatotoxicity in malnourhised male rats.

Effects of fermented oyster extract supplementation on free fatty acid and liver enzymes in older women with obesity.

This study aimed to investigate the effects of a 12-week intake of fermented oyster extract on free fatty acids and liver enzymes in older women with obesity and to provide basic data for improving liver function in older individuals with obesity. A randomized, double-blind, placebo-controlled clinical trial aimed to confirm the effects of fermented oyster extract intake on free fatty acid (FFA) levels and liver function in older women with obesity. The study included 40 older women with obesity with a body mass index ≥ 25 kg/m2. Participants were divided into a fermented oyster intake group (n = 20) and control group (n = 20). Serum FFA, aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), and gamma-glutamyl transferase (GGT) levels were measured at weeks 0 and 12. Our results showed an interaction effect between the two groups in terms of serum FFA levels (p<0.05), with a post-intervention decrease in the FSO group (p<0.05). AST, ALT, and GGT levels also showed an interaction effect between the two groups (p<0.05), with a significant postintervention decrease in the FSO group (p<0.05). The intake of fermented oyster extract significantly reduced FFA, ALT, AST, and GGT levels. These results suggested that the consumption of fermented oyster extract may improve liver function. However, the findings of this study were limited to elderly women with obesity, and the relatively short intake period and small sample size may limit the generalization of the results.

Investigation into the effect of acute exposure to chlorogenic acid in male wistar mice

Chlorogenic acid (CGA) is a natural polyphenolic compound widely present in various fruits, vegetables, and plant-based foods. It has gained considerable attention due to its potential health benefits including antioxidant, hepatoprotective, antibacterial, anti-inflammatory, anti-obesity, cardioprotective, neuroprotective, central nervous system stimulator, and anti-hypertensive amongst others. There is a dearth of information about acute exposure to chlorogenic acid which is also used as a food supplement. Ninety-six male Wistar mice were weight-matched into 8 groups (n=12). Group 1 was treated with distilled water, Group 2 received 1% ethanol, while Groups 3-8 were treated with 30, 60, 120, 240, 480 and 1,000 mg/kg body weight doses of CGA, respectively. Six animals were bled and sacrificed per group 24 hours post-treatment, and the liver and kidney were excised. Sections of the organs were fixed in 10% formalin for histopathological examination. Various antioxidant parameters were assayed in the liver and kidney samples using standard methods. A liver function test was also carried out on the liver samples. Haematological analysis was carried out as well as histopathology analysis of the liver and kidney samples. The remainder of the treated mice in each group were observed for mortality 24 hours post-treatment and for two weeks. Statistical analysis was performed using one-way analysis of variance (ANOVA) with p-values less than 0.05 considered to be significant. The results of this study show that chlorogenic acid led to dose-dependent increased levels of hydrogen peroxide and albumin, increased activity of alkaline phosphatase with decreased activities and levels of alanine aminotransferase, aspartate aminotransferase and bilirubin in the liver function while there were increased hydrogen peroxide levels in the kidney. The haematological parameters were not affected and the histopathological examination complemented the results with mild to moderate lesions in the liver and none in the kidney. Although, the lethal dose (LD 50-i.e., the dose at 50% mortality) was not established in this study. Therefore, chlorogenic acid should be ingested with caution.

Evaluation of intravenous Acepromazine-Butorphanol-Propofol anaesthesia on Canine serum biochemistry

In order to increase accuracy and ensure safety during surgical procedures, anaesthesia is a necessary precondition for most diagnostic and surgical procedures in humans and animals. This study was designed to determine the changes in serum biochemical parameters following Acepromazine-Butorphanol-Propofol (ABP-combination) and propofol alone (PRO alone) anaesthesia in dogs. Ten (10) apparently healthy dogs with mean age of 1.59±0.77 years and a mean body weight of 15.5±1.96 kg were obtained from live dog market in Maiduguri, North-eastern Nigeria. The dogs were divided randomly into two groups, ABP-combination and PRO-alone groups. Following premedication with Acepromazine at 0.02mg/kg and Butorphanol at 0.05mg/kg iv., 4mg/kg Propofol was used to induce total intravenous anaesthesia (TIVA) after five minutes of premedication in ABP-combination group, while PRO-alone at 6mg/kg was used to induce anaesthesia without premedication in PRO-alone group. Creatinine (sCr), Alanine aminotransferase (ALT) and Blood urea nitrogen (BUN) were determined using standard laboratory procedures. The ALT, sCr and BUN showed no difference (p&gt;0.05) within the group but were significantly (p&lt;0.05) different between the groups. The levels of Alanine aminotransferase in both ABP and PRO treatments showed significant difference (p&lt;0.05) at 10minutes, 1hour, 6hrs and 24hours. Significant difference (p&lt;0.05) was observed in sCr levels between the two treatments, at 10minutes, 1hour and 6hours respectively. Blood urea nitrogen in both treatments differed (p&lt;0.05) significantly at 6hours and 24hours post anaesthesia. The results of this study showed that ABP-combination following TIVA provides transient non-significant (p&gt;0.05) effect on serum biochemical parameters. Therefore, the combination of ABP can be used during surgical procedures in dog.

Comparative Analysis of Liver Enzyme Changes Before and After Korean Medicine Treatment in People with Obesity: A Retrospective, Multicenter, Observational Study

This retrospective, multicenter, observational study aimed to evaluate the effects of herbal medicine treatment on liver function in obese patients exhibiting elevated liver enzymes. Conducted from May 2023 to April 2024 at various Korean medicine clinics, the study included 84 patients who underwent herbal treatments for obesity. All participants had at least one liver function test (LFT) showing elevated levels of aspartic amino transferase (AST), alanine amino transferase (ALT), or gamma glutamyl transferase (GGT), and a subsequent LFT performed after a minimum of 90 days. The study excluded patients with potential confounding factors such as hepatitis, antibiotic usage, or recent surgeries.&lt;/br&gt;The study showed significant reductions in AST, ALT, and GGT levels, with AST and ALT improving to within the normal range and GGT approaching normal levels. Patients also experienced statistically significant reductions in weight and BMI, meeting the minimum clinically important difference threshold.&lt;/br&gt;These findings suggest that herbal treatments for obesity are not only safe for patients with obesity-related liver enzyme abnormalities but also effective in improving liver function. This study shows that herbal treatment is effective in the management of obesity-related liver disease and confirms the safety and efficacy of an obesity treatment herbal formula containing ephedra. Larger prospective studies are needed to confirm these findings.

Management of protective lung ventilation in children with a critical course of acute respiratory distress syndrome caused by SARS-CoV-2 coronavirus infection

the pandemic of coronavirus disease COVID-19 has created a serious threat to the public health system worldwide. With the beginning of the pandemic, it became clear that children infected by SARS-CoV-2, for unknown reasons, have a milder course compared to adults. In some cases, children are asymptomatic carriers of the infection. In light of today's scientific discoveries, contrary to initial reports, recent studies have shown that children are just as likely to contract the virus as adults, while vague symptoms and a milder course more often characterize the disease itself. However, it is worth noting that the true prevalence of asymptomatic SARS-CoV-2 infection is most likely underestimated since children are not tested for COVID-19 without obvious clinical symptoms. This fact has been confirmed by multiple blood tests indicating high titers of IgG to SARS-CoV-2. Compared to adults, the typical clinical manifestations of COVID-19 in children are fever, runny nose, cough, and general weakness. The laboratory test results indicate a normal level of leukocytes, lymphopenia, and an increased level of aspartate aminotransferase, alanine aminotransferase, D-dimer, and MB creatine kinase. Currently, there is no sufficient evidence that the etiotropic therapy is 100% successful. Yet a course of action such as respiratory system protection, control of fluids and electrolyte homeostasis, anti-cytokine therapy, preventative measures for thrombosis, and treatment for bacterial superinfection proved to be efficient at preventing the development of possible complications caused by SARS-CoV-2. Therefore, it is important to collect and accumulate new experiences\cases of respiratory system protection management of an acute respiratory syndrome with a critical course of acute respiratory distress syndrome caused by COVID-19 and implement practical treatment plans for healthcare facilities. The results were analyzed using clinical epidemiology methods. Children were admitted to the intensive care unit on an average of 6,6±0,62 days of illness and were more associated with systemic disorders and water-electrolyte imbalance, which required prosthetic respiratory function, correction of hemodynamics and water-electrolyte disorders, which was carried out in the infectious diseases department of anesthesiology and intensive care for an average of 5,2±0,7 days. In children in the clinical group, SARS-CoV-2 was verified by reverse transcription polymerase chain reaction of a nasopharyngeal swab and/or exhaled air condensate based on its positive results. Comprehensive treatment of patients with severe and extremely severe respiratory distress syndrome in coronavirus disease included respiratory and hemodynamic support, antiviral and antibacterial therapy, parenteral glucocorticosteroids and anticoagulants, which was in line with current national regulatory guidelines and local protocols. According to the criteria for choosing a method of respiratory function prosthetics, in more than half of the patients (62,2%) with hemoglobin oxygen saturation of less than 92%, while maintaining active respiratory capacity, respiratory support was provided by supplementing humidified oxygen through a face mask or nasal cannulas. In another 29,7% of patients, non-invasive ventilation was performed by constant positive airway pressure, with an oxygenation index of 0,4-0,5 and a positive end-expiratory pressure of 4-5 cm of water column. Children who had a critical course of acute respiratory syndrome caused by coronavirus infection COVID-19 (8,1%) and in whom non-invasive methods of respiratory support did not bring the desired therapeutic result were on invasive ventilation in the mode of auxiliary controlled ventilation or in the mode of synchronized intermittent forced ventilation. It should be noted that children who received respiratory support in the form of non-invasive ventilation by means of constant positive airway pressure required a lower concentration of oxygen in the inhalation mixture compared to patients on free-flow oxygen supplementation. The need for admission to the intensive care unit of children with COVID-19 is primarily associated with respiratory disorders caused by interstitial pneumonia. Oxygen supplementation was of paramount importance in patient management, primarily through noninvasive ventilation with constant positive airway pressure or free flow. The use of a pulmonary protective strategy in the treatment of acute respiratory distress syndrome caused by coronavirus disease COVID-19 in children requiring invasive ventilation was accompanied by a pronounced positive result, as it was not accompanied by side effects and resulted in a rapid recovery of patients.

Comparison of De Ritis Rate for Del Nido Versus Blood Cardioplegia in Patients Who Underwent Coronary Artery Bypass Graft Under Cardiopulmonary Bypass

Aim: Within the scope of this research, we aimed to compare the liver function tests, liver enzymes and De Ritis ratio (AST/ALT) of patients given Del Nido cardioplegia and blood cardioplegia in coronary heart surgery. Methods: This retrospective study included a total of 80 patients who underwent CPB-guided coronary heart surgery (CABG) with 40 Del Nido cardioplegia solutions and 40 blood cardioplegia solutions. CPB-guided coronary heart surgery patients given Del Nido cardioplegia solution were determined as the first group (Group 1), and patients given blood cardioplegia were determined as the second group (Group 2). Results: Preoperative and postoperative aspartate aminotransferase (AST), alanine aminotransferase (ALT), total bilirubin, direct bilirubin, and gamma-glutamyl transferase (GGT) levels of the groups were similar (p
