Psychological factors and biochemical indicators influencing sleep disturbance of patients with primary biliary cholangitis in China: a cross-sectional survey analysis.

The impact of primary biliary cholangitis (PBC) on sleep disturbance is relevant to treatment decision-making processes. Studies on sleep disturbance in Chinese patients with PBC are still lacking. We analyzed and compared the health-related quality of life (HRQoL) of 107 PBC patients by using the Pittsburgh Sleep Quality Index (PSQI) questionnaire, Generalized Anxiety Disorder Scale (GAD-7), Patient Health Questionnaire 9 (PHQ-9), Short Form (36) Health Survey Questionnaire (SF-36), Fatigue Visual Analog Scale (F-VAS). Patients' biochemical markers were also collected for correlation analysis with HRQoL. Receiver operating characteristic (ROC) curves and area under the curve (AUCs) were used to determine the diagnostic performance of PSQI, GAD-7, and biochemical markers for assessing the impaired liver function (Child-Pugh B-C) of PBC diagnosis. Sixty-two (57.9%) PBC patients suffered from poor sleep quality (PSQI >5). The global PSQI score was positively correlated with GAD-7 (r = 0.561, p < 0.001), and PHQ-9 scores (r = 0.652, p < 0.001). There was a negative correlation (r = -0.216, p = 0.025) between sleep quality and red blood cell (RBC) count. PBC patients with poor sleep quality had significantly higher GAD-7 scores (5 vs. 0, p < 0.001), PHQ-9 scores (5.5 vs. 0, p < 0.001), and lower albumin levels (39.6 vs. 37.6 g/L, p = 0.040) than those with good sleep quality. Based on the SF-36 scores, PBC patients with poor sleep quality had lower physical functioning scores (85 vs. 80, p = 0.022), role physical scores (100 vs. 75, p = 0.007), and worse mental health (60 vs. 56, p = 0.002) than those with good sleep quality. ROC analyses showed that the AUC and optimal cut-off values of the combination of PSQI, GAD-7, and RBC for assessing the impaired liver function in PBC diagnosis were 0.771 and 0.193, respectively. The sleep disturbance was strongly correlated with the severity of anxiety, depression, and RBC count in PBC patients. Meanwhile, PBC patients with poor sleep had poor HRQoL and lower albumin levels. It is feasible to use the combination of PSQI, GAD-7, and RBC for initial screening of the impaired liver function in PBC. Besides routine blood biochemical and imaging indicators, evaluating mental health-related indicators in PBC patients is imperative.

Study on the correlation between red cell distribution width, homocysteine, lipoprotein(a), and left atrial diameter in newly diagnosed nonvalvular atrial fibrillation patients.

This study aims to investigate the correlations between red cell distribution width (RDW), homocysteine (Hcy), lipoprotein(a) [Lp(a)], and left atrial diameter (LAD) measured by echocardiography in newly diagnosed nonvalvular atrial fibrillation (NVAF) (referred to as "new-onset AF") patients and their predictive value for new-onset AF. The findings of this study provide a basis for early clinical identification of the risk of new-onset AF. Eighty-nine newly diagnosed NVAF patients (46 males and 43 females) admitted to the Department of Cardiology, First Affiliated Hospital of Nanchang University, from January 2017 to January 2023 were included in the new-onset AF group. Over the same time, 88 sinus rhythm patients (44 males and 44 females) were included in the control group. Data, including demographic information, routine blood test parameters, biochemical indicators, and relevant values from cardiac color Doppler ultrasound, were recorded for all study subjects. Logistic regression analysis was used to explore the clinical characteristics of the indicators mentioned above in patients with new-onset AF. Receiver operating characteristic (ROC) curves were drawn to assess the predictive ability of these indicators for new-onset AF. Univariate analysis of biochemical indicators revealed differences between the two groups (p<0.05) in RDW, Hcy, and Lp(a). The univariate analysis also revealed differences (p<0.05) in RDW, Lp(a), Hcy, left atrial diameter (LAD), left ventricular end-diastolic diameter (LVEDD), interventricular septal thickness (IVST), and left ventricular ejection fraction (LVEF). Multivariable logistic regression analysis identified RDW (OR=2.38, 95% CI: 1.65-3.67), Hcy (OR=1.57, 95% CI: 1.37-1.86), and Lp(a) (OR=1.01, 95% CI: 1.00-1.01) as independent risk factors for the new-onset AF. In the subgroup analysis dichotomizing patients around the LAD cutoff value, the high-LAD group had higher RDW, Hcy, and Lp(a) (13.4 vs. 12.7, 15.0 vs. 10.9, 144.0 vs. 101.3, respectively). RDW, Hcy, and Lp(a) are elevated in patients with new-onset AF. They are positively correlated with LAD in these patients, indicating their role as risk factors for new-onset AF.

Interaction between coagulation and inflammatory system in liver disease: re-focus on hematological markers.

Aim: This study uses blood routine, coagulation and biochemical indicators to explore the relationship between the hematological parameters of patients with various types of liver diseases.Methods: The Kruskal-Wallis, Chi-squared and Fisher exact tests were used to compare the hematological parameters and clinical characteristics of three groups of patients with different degrees of liver disease. Spearman correlation analysis is used to analyze the correlation between two continuous variables. The logistic regression model evaluated the odds ratio between variables and disease changes. Receiver operating characteristic curve analysis was used to understand the predictive value of each index in relation to the progress of liver disease.Results: There are differences in inflammation and coagulation profiles among different types of liver diseases and there is a correlation between them. In addition to the traditional marker α-fetoprotein, the inflammatory marker c-reactive protein and the coagulation marker D-dimer also have good diagnostic value for liver injury.Conclusion: The coagulation and inflammation systems interact, are connected and play essential roles in the liver.

Dietary Nanozeolite Powder to Reduce Water Total Ammonia Nitrogen (TAN) and Improve Growth Performance and Plasma Biochemical Indices of Nile Tilapia (Oreochromis niloticus)

The effects of nanoscale synthetic zeolite powder (NZeP) levels in diet on water quality, growth performance, muscle proximate composition, and some blood biochemical indices of Nile tilapia (Oreochromis niloticus) fingerlings were evaluated in a 60‐day experiment. One hundred eighty fish with an average weight of 5.91 ± 0.45 g were distributed in three different groups of control (basal diet without NZeP), NZP0.5% (basal diet + 0.5% NZeP), and NZeP1% (basal diet + 1% NZeP) with triplicate. The zeolite particles were characterized via field emission scanning electron microscopy coupled with X‐ray energy dispersive spectroscopy (FE‐SEM/EDS), dynamic light scattering (DLS), and X‐ray diffraction (XRD) techniques. The results revealed that the total ammonia nitrogen (TAN) concentration in the NZeP dietary groups decreased compared to the control group after the 20th day of the experiment (p &lt; 0.05). The TAN concentration in the NZeP1% group was lower than in the NZeP0.5% group on days 50 and 60 (p &lt; 0.05). The final weight, weight gain, and average daily gain parameters were lower in the fish fed on NZeP1%‐supplemented diet than in other dietary groups (p &lt; 0.05). The feed conversion ratio value decreased in the NZeP dietary groups compared to the control (p &lt; 0.05). The lowest FCR value was recorded in the NZeP1% dietary group (p &lt; 0.05). The muscle crude protein content increased in the fish fed on diet supplemented with NZeP1% in comparison to the control (p &lt; 0.05). The aspartate aminotransferase (AST) concentration decreased in the plasma of fish fed on NZeP‐supplemented diets compared to the control (p &lt; 0.05). The plasma glucose concentration was lower in the NZeP1% dietary group than the control (p &lt; 0.05). In conclusion, the adding nanozeolite powder at a level of 1% to diet had positive effects on water quality, the growth performance, and muscle proximate composition of Nile tilapia fingerlings.

Does sodium bicarbonate based extra-cellular buffering support reduce high intensity exercise-induced fatigue and enhance short-term recovery assessed by selected blood biochemical indices?

Exercise-induced metabolic processes induce muscle acidification which contributes to a reduction in the ability to perform repeated efforts. Alkalizing agents such as sodium bicarbonate (NaHCO3) prevent large blood pH changes, however, there is no evidence on whether regulation of acid-base balance may also support whole body homeostasis monitored through heamatological and biochemical blood markers in a dose-dependent manner. Thirty Cross-Fit-trained participants were studied in a randomized, multi cross-over, placebo (PLA)-controlled double-blind manner in which they performed a control session (CTRL, without supplementation), three NaHCO3 visits (three different doses) and PLA (sodium chloride in an equimolar amount of sodium as NaHCO3). Each visit consisted of two 30-s Wingate tests separated by CrossFit-specific benchmarks (Wall Balls and Burpees - both performed for 3 min). Blood samples were collected at rest, immediately post-exercise and after 45 min recovery. Significant differences between visits appeared for blood pH, percentage of lymphocytes and granulocytes, red blood cells count and haemoglobin concentration at post-exercise and 45-min recovery, and for white blood cells count, percentage of monocytes, concentration of magnesium and creatinine at 45-min recovery. Most of the observed differences for heamatological and biochemical markers were significant compared to CTRL, but not different after PLA. NaHCO3 supplementation compared to PLA did not significantly affect exercise or recovery shifts in studied blood indicators. However, the changes in these markers after NaHCO3 and PLA in relation to CTRL indicate a possible role of sodium.

Association Between Plasma Homocysteine Level and Hyperuricemia in Elderly Patients With Hypertension

Objective To explore the association between plasma homocysteine (Hcy) level and hyper-uricemia (HUA) in the elderly patients with hypertension.Methods From March to August in 2018,9902 hypertensive patients ≥ 60 years were routinely tested for blood biochemical indicators in Wuyuan county,Jiangxi province.The patients were assigned into a HUA group and a normal uric acid group.Multivariate Logistic regression was adopted to analyze the relationship between Hcy level and the risk of HUA.Results Compared with the normal uric acid group,the HUA group showed increased incidence of hyperhomocysteinemia (99.9% vs.98.7%,P<0.001) and elevated Hcy level[16.8 (13.8-21.5) μmol/L vs.14.4 (12.3-17.7) μmol/L,P<0.001].The multivariate Logistic regression analysis showed that after adjusting for influencing factors,the risk of HUA in the patients with hyperhomocysteinemia was 2.92 times of that in the patients with a normal Hcy level.The threshold effect analysis showed that the Hcy level was positively correlated with the occurrence of HUA in the case of Hcy<20 μmol/L (OR=1.05,95%CI=1.04-1.07,P<0.001).In the case of Hcy ≥ 20 μmol/L,there was no correlation between Hcy level and HUA (OR=1.00,95%CI=0.99-1.00,P=0.055),and the likelihood ratio test showed statistically significant results (P<0.001).Conclusion The elderly with hypertension should pay attention to control the Hcy level,which will be helpful to prevent the occurrence of HUA.

Effects of Dietary Fish Meal Replacement with Composite Mixture of Chicken Meal, Krill Meal, and Plant Proteins on Growth, Physiological Metabolism, and Intestinal Microbiota of Chinese Perch (Siniperca chuatsi)

This trial aimed to investigate the influence of graded replacing fish meal (D1: 0.00%, D2: 27.27%, and D3: 54.55%) with mixed protein ingredients (i.e., chicken meal, krill meal, fermented soybean meal, and soy protein concentrate) on the growth performance, muscle nutritional composition, blood biochemical indices, gut bacterial community, and transcriptome of Chinese perch. Two hundred seventy Chinese perch were divided into three groups (90 per group) and the diet lasted for 56 days. Results showed that the weight gain rate and specific growth rate were significantly lower, and the feed conversion ratio was significantly higher in the D3 group than in fish fed D1 (P&lt;0.05), with no significant differences between the D1 and D2 groups (P&gt;0.05). The muscle crude protein content was highest in the D2 group, and the crude fat content was significantly different in the order: D3 &gt; D1 &gt; D2 (P&lt;0.05). The levels of serum triglycerides (TG) and low-density lipoprotein cholesterol in the D2 group were significantly lower than those in the D1 group (P&lt;0.05), but there was no significant difference compared to the D3 group (P&gt;0.05). The microbial community structure changed significantly. Mycoplasma showed the highest abundance in the D1 and D2 groups (P&lt;0.05), and Cetobacterium peaked in D2 group, and significantly higher than that in D1 group (P&lt;0.05). Network analysis and cohesion index calculation showed that both network complexity and cohesion peaked in D2 group, and Cetobacterium was highly correlated with the cohesion index (P&lt;0.05). Further, muscle transcriptome analysis results showed that compared with the control group, differentially expressed genes were clustered (Q &lt; 0.05) in the arginine and proline metabolism pathways in D2 group. Fish in D3 group significantly (Q &lt; 0.05) affected genes involved in KEGG pathways of ribosome, circadian rhythm, thermogenesis, insulin signaling pathway, fatty acid degradation, oxidative phosphorylation, and apoptosis. In conclusion, under the experimental conditions, the replacement of 27.27% of fish meal by the compound protein did not have a negative impact on the growth performance of Chinese perch and could improve muscle quality, lipid metabolism, and the interaction of intestinal microbiota.

Analysis of nutritional risk, skeletal muscle depletion, and lipid metabolism phenotype in acute radiation enteritis.

Radiation enteritis, which often occurs during radiation-induced acute intestinal symptoms (RIAIS), is the most common and important complication during radiotherapy for cervical cancer. RIAIS caused by abdominal and pelvic radiotherapy will affect nutrient intake, digestion, absorption, and metabolism, leading to malnutrition or poorer nutritional status. In patients with malignant tumors, malnutrition can adversely affect the curative effect and response of radiotherapy by reducing radiosensitivity, affecting the precision of radiotherapy placement and increasing the incidence of radiotherapy-related adverse reactions. To analyze nutritional risk, skeletal muscle depletion, and lipid metabolism phenotype in acute radiation enteritis. Fifty patients with cervical cancer received external beam radiotherapy, and 15 patients received brachytherapy after external beam radiotherapy. Body weight, body composition parameters, nutritional risk screening (NRS) 2002 score, and blood biochemical indices of patients with cervical cancer during periradiation were tested by a one-way repeated measures analysis of variance. Metabolomics analysis was used to identify characteristic lipid metabolism pathways. Clinical factors that affect linoleic acid changes were screened using the generalized evaluation equation. Among the 50 patients, 37 had RIAIS, including 34 patients with grade 1-2 RIAIS and 3 patients with grade 3 RIAIS. The NRS 2002 score of patients who underwent cervical cancer radiotherapy continued to increase during the periradiation period, and 42 patients who underwent cancer radiotherapy had nutritional deficits (NRS 2002 score ≥ 3 points) at the end of radiotherapy. Correlation analyses revealed that body weight and body mass index changes were closely associated with body fat content (R2 = 0.64/0.51). The results of the univariate analysis showed that radiotherapy time, percentage reduction of serum albumin, and percentage reduction of serum prealbumin were the key factors affecting skeletal muscle exhaustion (P < 0.05). Metabolomic analysis of fecal supernatants of cervical cancer patients during the periradiation period revealed the involvement of linoleic acid, cholic acid, arachidonic acid, and N-acetyl-L-benzene alanine in the metabolic pathway of linoleic acid. Cervical cancer radiotherapy patients faced nutritional risks, decreased serum albumin synthesis, and increased risk of skeletal muscle exhaustion. Linoleic acid was a biomarker of high nutritional risk.

BIOCHEMICAL PROFILE OF FULL-TERM NEWBORNS WITH DIFFERENT PROTEIN SUPPLY ON THE BACKGROUND OF THE TREATMENT OF CRITICAL DISEASES OF THE PERINATAL PERIOD

Study of the effect of increased protein and L-carnitine supplementation in term neonates with critical illnesses on the biochemical profile and improvement of intensive care outcomes.&#x0D; Objective: assessment of the impact of increased L-carnitine and protein supplementation on the physical development and biochemical profile of newborns who were in a critical condition.&#x0D; Materials and methods. The life indicators of 59 full-term children, who were randomly divided into two groups, were studied. The first group (n = 30) received standard nutrition with mother's milk or formula, the second group (n = 29) received protein-fortified food and L-carnitine supplementation during the hospital stay.&#x0D; The results. Babies of both groups had statistically equivalent characteristics at the beginning of the study. Against the background of higher consumption of proteins, the number of non-protein calories per 1 g of protein in the study group was 28.68 kcal/kg/day (27.50; 29.80), against the indicator of the standard diet group of 42.37 kcal/kg/day (41 .60; 38.00), with U = 28.0000; p = 0.000001. Carnitine supplementation in the GZ group led to an increase in the level of free carnitine in the last blood plasma samples of newborns. In general, the proposed nutrition strategy was accompanied by better indicators of physical development of children. Children who consumed more protein were transferred from the intensive care unit earlier – 10.00 (8.00; 12.00) days, against 12.00 (11.00; 16.00) days, with U = 235.00; p = 0.0024; previously discharged from the hospital -21.00 (19.00; 27.00) days, against 26.50 (22.00; 31.00) days at U = 267.00, p = 0.0109. This strategy proved to be safe, as confirmed by normal levels of phenylalanine and blood biochemical indicators at all stages of the examination of children, including urea nitrogen and creatinine.&#x0D; Conclusions. Short-term increased consumption of protein against the background of carnitine supplementation improves the results of the physical development of newborns, does not lead to deviations in the biochemical profile, and is safe.

The association of tonsillar microbiota with biochemical indices based on obesity and tonsillar hypertrophy in children

The correlation between tonsil microbiome and tonsillar hypertrophy has not been well established. Given that oral dysbiosis is related to several metabolic diseases and that tonsillar hypertrophy leads to disordered breathing during sleep and obesity in children, it is necessary to investigate the relationship between the oral microbiome and tonsillar hypertrophy. After 16S rRNA amplicon sequencing of tonsillectomy samples, we evaluated the correlation between the tonsil microbiome and biochemical blood indices in pediatric patients who underwent tonsillectomy. Groups are classified into two categories: based on BMI, and grades 2, 3, and 4 based on tonsil size. Children with obesity and tonsillar hypertrophy have similar microbiome compositions and induce comparable changes in microbiome abundance and composition, confirming the association from a metagenomic perspective. In addition, obesity and tonsillar hypertrophy demonstrated a strong correlation with the Proteobacteria to Firmicutes (P/F) ratio, and among various biochemical indicators, alanine aminotransferase (ALT) levels increase with obesity and tonsillar hypertrophy, indicating a possible association of tonsil microbiome and liver metabolism. These novel findings demonstrate the significance of the tonsil microbiome and suggest the need for tonsil regulation, particularly during childhood.

Correlation between long-term glycemic variability and cognitive function in middle-aged and elderly patients with type 2 diabetes mellitus: a retrospective study.

To investigate the correlation between long-term glycemic variability and cognitive function in middle-aged and elderly patients with type 2 diabetes mellitus (T2DM). This retrospective analysis includes 222 patients hospitalized at Second Affiliated Hospital of Anhui Medical University from June 2021 to June 2023. Cognitive function was assessed using the Montreal Cognitive Assessment (MoCA) and Mini-Mental State Examination (MMSE). All patients were categorized into the MCI group and the non-MCI group based on their MoCA score. Long-term blood glucose fluctuations were measured using glycated hemoglobin A1c standard deviation (HbA1c-SD) and fasting plasma glucose standard deviation (FPG-SD). The study compared general clinical data, blood biochemical indicators, and glycemic variability indicators between the two groups. The differences between the groups were compared using t-test, Chi-Square Test, or Mann-Whitney U test. Kendall's correlation analysis, multivariate logistic regression analysis and ROC curve correlation analysis were further used to analyze the correlation and diagnostic power. The differences in age, MoCA scores, MMSE scores, HOMA-β, HbA1c-M, HbA1c-SD, FPG-M, FPG-SD, eGFR, Smoking, GLP-1RA and SGLT-2i usage were statistically significant between the two groups (P<0.05). Kendall's correlation analysis showed that age, HbA1c-M, HbA1c-SD, FPG-M, and FPG-SD was negatively correlated with MoCA scores; meanwhile, the HOMA-β, and eGFR was positively correlated with MoCA scores. Multiple logistic regression analysis revealed that HbA1c-SD, FPG-SD and Smoking were risk factors for cognitive dysfunction, while eGFR, GLP-1RA and SGLT-2i usage was a protective effect. The area under the curve (AUC) values for predicting MCI prevalence were 0.830 (95% CI [0.774-0.877], P<0.001) for HbA1c-SD, 0.791 (95% CI [0.655-0.808], P<0.001) for FPG-SD, and 0.698 (95% CI [0.633-0.757], P<0.001) for eGFR. The optimal diagnostic values were 0.91, 1.32, and 74.81 ml/min/1.73 m2 for HbA1c-SD, FPG-SD, and eGFR, respectively. Cognitive function in middle-aged and elderly T2DM patients is influenced by long-term blood glucose variability, with poorer cognitive function observed in individuals with higher blood glucose variability. The impact of HbA1c-SD on MCI exhibited a greater magnitude compared to that of PFG-SD and smoking. Additionally, renal function, GLP-1RA and SGLT-2i usage exert positive effects on cognitive function.

Multiomics was used to clarify the mechanism by which air pollutants affect chronic obstructive pulmonary disease: A human cohort study

Exposure to air pollutants has been associated with various adverse health outcomes, including chronic obstructive pulmonary disease (COPD). However, the precise underlying mechanism by which air pollution impacts COPD through remains insufficiently understood. To elucidated the molecular mechanism by which air pollutant exposure contributes to alterations in the gut microbiome and metabolism in AECOPD patients, we employed metagenomics and untargeted metabolomics to analyse the gut microbial, faecal, and serum metabolites. The correlations among air pollutants, gut microbes, serum metabolites, and blood biochemical markers were assessed using generalised additive mixed models and Spearman correlation analysis. The findings revealed that for every 10 μg/m3 increase in PM2.5 concentration, the α-diversity of the gut flora decreased by 2.16% (95% CI: 1.80%−2.53%). We found seven microorganisms that were significantly associated with air pollutants, of which Enterococcus faecium, Bacteroides fragilis, Ruthenibacterium lactatiformans, and Subdoligranulum sp.4_3_54A2FAA were primarily associated with glycolysis. We identified 13 serum metabolites and 17 faecal metabolites significantly linked to air pollutants. Seven of these metabolites, which were strongly associated with air pollutants and blood biochemical indices, were found in both serum and faecal samples. Some of these metabolites, such as 2,5-furandicarboxylic acid, C-8C1P and melatonin, were closely associated with disturbances in lipid and fatty acid metabolism in AECOPD patients. These findings underscore the impact of air pollutants on overall metabolism based on influencing gut microbes and metabolites in AECOPD patients. Moreover, these altered biomarkers establish the biologic connection between air pollutant exposure and AECOPD outcomes.The identification of pertinent biomarkers provides valuable insights for the development of precision COPD prevention strategies.

Association of eosinopenia with worsening prognosis in hospitalized Azvudine-treated COVID-19 patients: a retrospective cohort study.

Current guidelines prioritize the use of Azvudine in Coronavirus Disease 2019 (COVID-19) patients, while biomarkers for prognosis in Azvudine-treated COVID-19 patients are still lacking. Here, we aim to assess the prognostic value of eosinopenia in Azvudine-treated COVID-19 patients. We retrospectively reviewed 290 consecutive Azvudine-treated hospitalized COVID-19 patients. Clinical characteristics and prognosis data were analyzed between patients with eosinopenia and with normal eosinophil levels. A total of 290 patients were enrolled in this study, with a median age of 69 years. Among them, 40.69% presented with eosinopenia and 59.31% had normal eosinophil levels. Common symptoms included cough (87.6%), expectoration (76.2%), fever (67.9%), poor appetite (47.2%), and polypnea (46.6%). Compared to patients with normal eosinophil levels, those with eosinopenia were older and less likely to experience fatigue (25.4% vs. 39.0%, P=0.016). Significant differences in laboratory parameters, particularly in blood routine and blood biochemical indicators, were observed between the two groups. Patients with eosinopenia were also less likely to develop severe illness subtypes, requiring more medication and oxygen support. The Cox proportional hazard model showed that eosinopenia was associated with worsening progression in Azvudine-treated COVID-19 patients (adjusted hazard ratio=2.79, 95% confidence interval: 1.04, 7.50), adjusting for potential confounders. Eosinopenia is associated with worsening prognosis in Azvudine-treated COVID-19 patients.

Effects of the fermented soya waste supplementation with various probiotic sources on growth performance of crossbred rabbits

The experiment on the growth of rabbits involved a completely randomized design with six treatments and six replications, with two rabbits with balanced sexual distribution per trial unit. The six treatments included different methods of treating soya waste, including cooking it (T1), and five commercial probiotics, namely the biotic probiotic (T2), garlic powder probiotic (T3), M-VS05 probiotic (T4), UV-Bacillus probiotic (T5), and the alive probiotic (T6). The soya waste was anaerobically fermentedin three days before feeding it to the experimental rabbits. The results showed that the use of probiotic treatments improved nutrient intake, nutrient digestibility, digestible nutrients, and nitrogen retention (P&gt;0.05). The T3 treatment resulted in the highest daily weight gain (P&lt;0.05) and economic returns for the experimental rabbits. There were no significant differences in the physiological and biochemical indicators of rabbit blood between treatments (P&gt;0.05). The group of rabbits fed with T1 treatment (without probiotics) had a much higher density of E. coli in their fecesthan the other five groups. These findings indicated that treating anti-nutrients in soya waste with probiotics could replace heat treatment and result in better growth performance, improved daily weight gain, and increased profits for growing rabbits.

Relationship between the lymphocyte to C‑reactive protein ratio and coronary artery disease severity.

Coronary atherosclerosis is a chronic systemic inflammatory disease. Laboratory parameters such as the neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR) and systemic immune inflammation index (SII) have been used to assess inflammation degree and coronary artery disease (CAD) severity. The lymphocyte-to-C-reactive protein ratio (LCR) is a new SII. However, its relationship with CAD development and severity is unclear. A total of 1,107 patients (479 in control group, 628 in CAD group) underwent coronary angiography. The routine and biochemical indices of the venous blood of patients were assessed before coronary angiography. LCR, SII, NLR and PLR were calculated and statistical analyses were performed. Propensity score matching (PSM) and a logistic regression model were used to analyze the relationship between LCR and CAD. After the PSM, 384 pairs of patients with or without CAD were successfully matched. After the median binary classification of all indicators, uni- and multivariate logistic regression analyses showed that platelet count was an independent risk factor and LCR was an independent protective factor. Using the same method, in the coronary heart disease severity group, 212 pairs were successfully matched and NLR and PLR were independent risk factors, while LCR was an independent protective factor. In conclusion, LCR is an independent protective factor against CAD development and severity.

N-nitrosamines induced gender-dimorphic effects on infant rats at environmental levels

The safety of drinking water has always been a concern for people all over the world. N-nitrosamines (NAs), a kind of nitrogenous disinfection by-products (N-DBPs), are generally detected as a mixture in drinking water at home and abroad. Studies have shown that individual NAs posed strong carcinogenicity at high concentrations. However, health risks of NAs at environmental levels (concentrations in drinking water) are still unclear. Therefore, the potential health risks of environmentally relevant NAs exposure in drinking water needs to be conducted. In this study, blood biochemical analysis and metabolomics based on nuclear magnetic resonance (NMR) were performed to comprehensively investigate NAs induced metabolic disturbance in infant rats at environmental levels. Results of blood biochemical indices analysis indicated that AST in the serum of male rats in NAs-treated group exhibited a significant gender-specific difference. Multivariate statistics showed that two and eight significantly disturbed metabolic pathways were identified in the serum samples of NAs-treated male and female rats, respectively. In the urine samples of NAs-treated female rats, glycine, serine, and threonine metabolism pathway was significantly disturbed; while three significantly disturbed metabolic pathways were found in the urine of NAs-treated male rats. Finally, results of spearman correlation coefficients suggested that the disturbances of metabolism profile in serum and urine were correlated with changes in the gut microbiota (data derived from our published paper). Data presented here aimed to generate new health risk data of NAs mixture exposure at environmental levels and provide theoretical support for drinking water safety management. Environmental implicationN-nitrosamines (NAs) are a kind of nitrogenous disinfection by-products (N-DBPs) generated during drinking water disinfection processes. Herein, health risks of NAs at environmental levels (concentrations in drinking water) are investigated using blood biochemical analysis and nuclear magnetic resonance (NMR)-based metabolomics. Results confirmed NAs induced gender-specific on the metabolism in rat and the disturbances of metabolism profile in serum and urine were correlated with changes in the gut microbiota. Data presented here aimed to generate new health risk data of NAs mixture exposure at environmental levels and provide theoretical support for drinking water safety management.

Assessing causal associations of hyperparathyroidism with blood counts and biochemical indicators: a Mendelian randomization study.

The existing literature on the relationship of hyperparathyroidism with both blood counts and biochemical indicators primarily comprises observational studies, which have produced inconsistent findings. This study aimed to evaluate the causal relationship between hyperparathyroidism and blood counts and biochemical indicators. Mendelian randomization (MR) analyses were conducted to investigate the associations between hyperparathyroidism and the identified 55 blood counts and biochemical indicators. The genome-wide association study (GWAS) for hyperparathyroidism data was obtained from FinnGen, while the GWASs for the blood counts and biochemical indicators were sourced from the UK Biobank (UKBB). The MR analysis using the inverse-variance weighted (IVW) method revealed potential causality between genetically predicted hyperparathyroidism and seven out of 55 blood counts and biochemical indicators. These markers include "Platelet count" (Beta = -0.041; 95% CI: -0.066, -0.016; p = 0.001), "Platelet distribution width (PDW)" (Beta = 0.031; 95% CI: 0.006, 0.056; p = 0.016), "Mean platelet volume (MPV)" (Beta = 0.043; 95% CI: 0.010, 0.076; p = 0.011), "Vitamin D" (Beta = -0.038; 95% CI: -0.063, -0.013; p = 0.003), "Calcium (Ca2+)" (Beta = 0.266; 95% CI: 0.022, 0.509; p = 0.033), "Phosphate" (Beta = -0.114; 95% CI: -0.214, -0.014; p = 0.025), and "Alkaline phosphatase (ALP)" (Beta = 0.030; 95% CI: 0.010, 0.049; p = 0.003). The findings of our study revealed a suggestive causal relationship between hyperparathyroidism and blood cell count as well as biochemical markers. This presents a novel perspective for further investigating the etiology and pathological mechanisms underlying hyperparathyroidism.

Comparison of growth performance, meat quality, and blood biochemical indexes of Yangzhou goose under different feeding patterns

The East China region is the main market for the breeding and consumption of meat geese in China, in order to provide data reference for small and medium-sized farms and farmers to choose breeding methods and growth performance. This study selected 300 Yangzhou geese as materials and determined the number of geese in each group according to different modes. The meat quality, blood biochemical indicators, and economic benefits of 4 common feeding methods (Group I: full concentrate feeding; Group II: concentrate feeding in the first stage + 3% fat addition in the later stage; Group III: concentrate feeding + pasture supplementation; Group IV: grazing feeding + concentrate) in East China were analyzed. The results are as follows: The average daily weight gain of Yangzhou geese in Group IV at 5 to 8 wk old was the highest, with the highest feed utilization rate. The body weight at 8 wk old was significantly higher than that of the group III (P < 0.05). The total mortality rate of Group I and II remained at a relatively low level, while the mortality rates of Group III and IV exceeded 17%. The SR, FECR, and FECW of female geese in Groups II, III, and IV were significantly higher than those in Control group I (P < 0.05). Different feeding methods have little effect on the quality of goose breast muscles, while in terms of leg muscles, Group II has the highest binding force, significantly higher than Group I (P < 0.05). The rate of chest muscle loss in group III was significantly higher than that in groups I and II (P < 0.05). However, the pH of leg muscles in groups I, II and III was significantly higher than that in group IV (P < 0.05). Group II has the highest protein and collagen content, and Group I has the highest fat content. Except for the significantly higher histidine content in Groups I And II compared to those in Groups III and IV (P < 0.05), there was almost no significant difference in amino acid content among the groups (P > 0.05). There was no significant difference in ALB/GLO content among the 3 groups of Groups II to IV, but they were all significantly higher than those of Group I (P < 0.05). There was no statistically significant difference in other indicators among the groups (P > 0.05). There was no significant difference in the content of Ca, Cu, Fe, P, Zn, and other elements in the muscles between the groups (P > 0.05). This study solved the problems of slow growth, poor meat performance, and low economic benefits in meat goose breeding, providing theoretical basis and data support for meat goose breeding enterprises and farmers to choose appropriate breeding modes.

Effect of Individualized Nutritional Therapy Combined with Low-intensity Continuous Exercise on Pregnancy Outcomes in Patients with Gestational Diabetes

Objective: To study the effect of individualized nutrition therapy combined with low intensity continuous exercise on gestational diabetes mellitus (GDM) control and pregnancy outcome. Methods: A total of 72 GDM patients diagnosed and treated in our hospital from October 2022 to October 2023 were randomly divided into an observation group and a control group. Individualized nutritional therapy combined with low-intensity continuous exercise therapy and conventional therapy were given, respectively. The blood glucose level, biochemical indexes, depression score, anxiety score and pregnancy outcome of the patients were observed and compared. Results: After individualized nutrition therapy combined with low-intensity continuous exercise, compared with the control group, the levels of fasting blood glucose, 2h postprandional blood glucose, glycated protein, albumin, total cholesterol, and triacylglycerol of the patients in the observation group were significantly reduced, and the depression and anxiety of the patients in the observation group were significantly alleviated, and the pregnancy complications were significantly reduced. Conclusion: Individualized nutrition therapy combined with low-intensity continuous exercise can effectively control gestational diabetes and improve pregnancy outcomes.
