Drug-independent control strategy of clostridial infection in broiler chickens using anti-toxin environmentally friendly multienzymes

The study investigated the effect of enzymes as a toxin detoxifier (DETOXIZYME) dietary supplementation on performance during growth, blood chemistry, and immunity under clostridia infection in chickens. A total of 480, day-old male chicks were randomly distributed to four groups, with six replicates of 20 birds each. The first control negative treatment (A) fed the basal formula as commercial feed prepared following the strain's needs, the second control positive group (B) fed the basal formula challenged with Clostridium perfringens (C. perfringens) type A, the third group (C) fed the basal formula with 100 g DETOXIZYME/ton of feed and challenged with clostridia, and the fourth group (D) fed the control basal formula with 100 g DETOXIZYME/ton of feed. DETOXIZYME dietary supplementation significantly boosted body weight (BW), body weight gain (BWG), feed intake (FI), and European production efficiency factor (EPEF) and improved the feed conversion rate (FCR) of the broilers. The dietary supplementation of DETOXIZYME significantly increased carcass trait and spleen. However, liver and abdominal fat weight significantly decreased compared with clostridia-challenged groups. The values of alanine aminotransferase (ALT), aspartate aminotransferase (AST), uric acid, creatinine, and Malondialdehyde (MDA) were decreased. While calcium, phosphate, zinc, and glutathione peroxidase (GPx) levels were improved in birds that took basal formulas fortified with DETOXIZYME contrary to the other treatment groups during 35 days of age. Plasma total cholesterol, triglyceride, and low-density lipoprotein (LDL) values were reduced versus the other treatment groups. Dietary supplementation of DETOXIZYME increased total protein, albumin, globulin, and Newcastle Disease (ND) immunity titer levels in the overall period compared to other groups. Dietary DETOXIZYME supplementation decreased clostridia and E. coli bacteria counts and improved gut morphometry. In conclusion, dietary supplementation of DETOXIZYME had a positive impact on performance, blood biochemistry, immunity, and bacterial counts and improved the gut morphology in broilers under clostridia infection.

The Role Of Serum Uric Acid And Uric Acid To Albumin Ratio For Predicting Of Lymph Node Metastasis In Lung Cancer Treated Surgically By Vats.

In recent years, a correlation between prognosis of various cancers and inflammation has been emphasized in many studies. Uric acid which is a purine metabolite is one of the serum inflammation markers. Albumin is a major component of serum protein and it is used as a parameter reflecting nutritional status and cancer aggressiveness. Here, we have investigated whether preoperative serum uric acid levels, albumin levels, and uric acid to albumin ratio predict lymph node metastasis in non-small cell lung cancer treated surgically by VATS. The medical records of patients underwent VATS lobectomy-segmentectomy for non-small cell lung cancer between January 2015 and December 2020, were reviewed retrospectively. Cut-off values of preoperative serum uric acid, albumin and uric acid to albumin ratio were determined by Receiver Operating Characteristics (ROC) analysis. Groups with and without lymph node metastasis were created according to hilar and/or mediastinal lymph node metastasis. In addition, high and low groups were created according to preoperative uric acid levels and uric acid to albumin ratio. Pearson chi-square test was used investigate whether any significant correlation between the groups. A total of 115 patients were included in the study. Lymph node metastasis in N1 and N2 stations was detected in 11 and 18 patients, respectively. Cut-off values for uric acid and uric acid to albumin ratio were 5.97 mg/dL and 1.28x10-3, respectively. There was a statistically significant correlation between lymph node metastasis and high uric acid levels (p=0.008, OR: 3.2) and high uric acid to albumin ratio (p=0.03, OR: 2.6). Preoperative serum uric acid and uric acid to albumin ratio can predict the lymph node metastasis in non-small cell lung cancer treated surgically by video assisted thoracic surgery.

Could Basal Uric Acid Levels Be an Important Biomarker for Prediction of Acute Renal Injury in Patients With Sepsis in the Intensive Care Unit?

Background: Sepsis is an important risk factor for the development of acute renal injury (ARI) among patients admitted to the intensive care unit (ICU). There are limited studies showing that increased uric acid level is an important risk factor for the development of ARI. The present study was carried out to find out whether increased basal uric acid levels play an important role in predicting the development of ARI and whether it could be used as a biomarker for this. Materials and Methods: This retrospective study included patients aged≥18 years who were admitted to the ICU of Yüzüncü Yıl University Medical Faculty Hospital from September 2018 to December 2020. Group 1 comprised 100 patients developing ARI and group 2 comprised 110 patients who did not develop ARI. Laboratory test values and Simplified Acute Physiologic Score II (SAPS II) data on the first day of ICU admission were obtained from archive records. Results: During the 10-day follow-up of patients included in the study, the ARI development rate was 57.3%. Basal serum uric acid levels were higher in group 1 compared to group 2 (P=0.001). Based on the results of the multivariate logistic regression analysis, basal serum uric acid values and albumin and SAPS II values had independent correlations with ARI (P<0.001). Conclusion: We believe that increased basal uric acid levels examined in patients admitted to the ICU with sepsis diagnosis may be an important biomarker for the prediction of ARI.

Clinical Values of Serum Uric Acid Levels in the Occurrence of Cognitive Impairment in Alcohol-Dependent Patients.

Studies have confirmed that uric acid is involved in the regulation of cognitive function. This study aimed to investigate the expression of serum uric acid in alcohol-dependent patients and evaluate its clinical diagnostic value for cognitive impairment. Blood sample was collected for assessment of serum uric acid levels. Montreal Cognitive Assessment Scale scores were obtained to assess cognitive function. Anxiety and depression scores on the Symptom Check List 90 scale were used to assess mental health status. The alcohol-dependent patients were divided into non-cognitive impairment and cognitive impairment groups according to Montreal Cognitive Assessment Scale score, and the serum uric acid levels of these groups were analyzed. The receiver operating characteristic curve evaluated the diagnostic value of serum uric acid in cognitive impairment patients. Pearson correlation coefficient evaluated the correlation between uric acid and Montreal Cognitive Assessment Scale score, anxiety score, and depression score. Multivariate logistic regression analyzed the association between each index and cognitive impairment in patients. Serum uric acid was higher in patients than in controls (P < .001). Uric acid was significantly increased in cognitive impairment patients than in non-cognitive impairment patients (P < .001). Serum uric acid has certain diagnostic value in patients with cognitive impairment. Anxiety score and depression score were positively correlated with uric acid level, while Montreal Cognitive Assessment Scale score was negatively correlated with uric acid. Additionally, serum uric acid, Montreal Cognitive Assessment Scale score, and anxiety and depression scores were the risk factors for cognitive impairment in patients (P < .05). The abnormal expression of uric acid has a high diagnostic accuracy for distinguishing cognitive impairment from non-cognitive impairment.

Acute kidney injury in patients with idiopathic membranous nephropathy: influencing factors and prognosis

Aim Idiopathic membranous nephropathy (IMN) is a common type of nephrotic syndrome, and is associated with acute kidney injury (AKI). We investigated the association of multiple variables with AKI in patients with IMN. Methods The data of 187 patients with biopsy-proven IMN were examined. Renal outcome was defined as progression to end-stage renal disease (ESRD). Binary logistic regression and Kaplan–Meier’s analysis were used for statistical analysis. Results During follow-up, 46 (24.6%) patients developed AKI. The incidence of AKI was greater in males than females (p < .01). The AKI group had higher uric acid, lower serum PLA2R antibody positive, and worse baseline kidney function (all p < .01). Most patients in the AKI group had stage I (71.74%) or stage II (21.74%). The AKI group had higher renal tubular injury score and chronicity index (both p < .05). Binary logistic regression indicated that uric acid and baseline estimated glomerular filtration rate (eGFR) were independent risk factors for AKI in patients with IMN (p < .05). The optimal cutoff value of serum uric acid for predicting AKI was 402.50 μmol/L and the baseline eGFR was 96.83 mL/min/1.73 m2. Kaplan–Meier’s analysis showed that the cumulative renal survival rate was lower in the AKI group (p = .047). Conclusions AKI increases the risk of poor prognosis in IMN patients and the high uric acid and low baseline eGFR were considered independent predictors for developing AKI in patients with IMN.

Cardiopulmonary Exercise Testing in Children and Young Adolescents after a Multisystem Inflammatory Syndrome: Physical Deconditioning or Residual Pathology?

Multisystem inflammatory syndrome in children (MIS-C) is a serious health condition that imposes a long-term follow-up. The purpose of our pilot study is to evaluate the usefulness of the cardiopulmonary stress test (CPET) in the follow-up after MIS-C. All patients admitted for MIS-C in our hospital in the 12 months preceding the date of observation were considered for inclusion in the study. Pre-existing cardio-respiratory diseases and/or the lack of collaboration were the exclusion criteria. At enrolment, each subject passed a cardiological examination, rest ECG, echocardiogram, 24 h Holter-ECG, blood tests, and a CPET complete of spirometry. A total of 20 patients met the inclusion criteria (11.76 ± 3.29 years, 13 male). In contrast to the normality of all second-level investigations, CPET showed lower-than-expected peakVO2 and peak-oxygen-pulse values (50% of cases) and higher-than-expected VE/VCO2-slope values (95% of cases). A statistically significant inverse correlation was observed between P-reactive-protein values at admission and peakVO2/kg values (p = 0.034), uric acid values at admission, and peakVO2 (p = 0.011) or peak-oxygen-pulse expressed as a percentage of predicted (p = 0.021), NT-proBNP values at admission and peakVO2 expressed as a percentage of predicted (p = 0.046). After MIS-C (4-12 months) relevant anomalies can be observed at CPET, which can be a valuable tool in the follow-up after this condition.

The Effect of Ursolic Acid and Hyperinsulinemia on the Liver and Kidney Function of Alloxan-Induced Diabetic Male Rabbits

The study aimed to examine the effect of extracted and standard ursolic acid in addition to hyperinsulinemia compared to vitamin B complex on the liver and kidney function of alloxan-induced diabetic male rabbits. The liver and kidney functions were determined and analyzed by one–way of a NOVA at variance software at a P-Value of 0.05. The result showed a significant decrease in aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), and uric acid values in the groups treated with standard and extraction ursolic acid(UA) compared to the diabetic group. The rabbit group that was treated with vitamin B complex recorded a significant decrease in the three liver enzymes, uric acid, and creatinine values than the diabetic group. In addition, the rabbit group that was treated with hyperinsulinemia recorded a significant increase in aspartate aminotransferase (AST) and creatinine values than the diabetic rabbit group. While the histological results in the groups treated with standard and extraction ursolic acid had a clear ameliorative effect in liver and kidney function tests better than hyperinsulinemia, also vitamin B complex caused some good effects.

Prognostic value of hyperuricemia in patients with heart failure

In patients with heart failure, hyperuricemia is often observed. The purpose of our study is to determine the relationship of serum uric acid with biochemical characteristics of heart failure and to determine its diagnostic and prognostic value for the outcome of the disease. Material and methods: the study was based on the results of the study of 117 patients with asymptomatic hyperuricemia who applied to the clinic from September 2019 to January 2022. We determined the relationship between serum uric acid and the characteristics of heart failure, using ROCK analysis we determined the sensitivity and specificity of uric acid for the outcome of heart failure. Results: Creatinine - r=0.478**, p=0.000 shows a reliable positive correlation with uric acid concentration; CRP - r=0.742**, p=0.000; BNP - r=0.599**, p=0.000, and eGFR - r=-0.184*, p=0.046 shows a reliable negative correlation; According to the degree of heart failure, the concentration of uric acid was distributed as follows: NYHAI - 5.48+0.94; NYHAII - 6.71+1.36; NYHAIII - 8.10+1.14; NYHA IV - 8.78+1.01 (F=29.24, p&lt;0.0001). sensitivity - 00.810(95%CI: 0.709-0.911); specificity - 0.814(95%CI: 0.714-0.913); predictive value of negative result 0.814(95%CI:0.714-0.913); Prognostic value of a positive result - 0.810(95%CI:0.709-0.911); Diagnostic accuracy of the test - 0.812(95%CI:0.741-0.883). Conclusions: Serum uric acid values correlate with renal function and heart failure characteristics. The value of uric acid can be used as an additional test to predict the outcome of heart failure.

Inflammation Related to Association of Low Uric Acid and Progression to Severe Disease in Patients Hospitalized for Non-Severe Coronavirus Disease 2019

Uric acid has antioxidant properties. To examine whether a low uric acid level is associated with severe coronavirus disease 2019 (COVID-19) progression via inflammation, alveolar damage, and/or coagulation abnormality, a retrospective observational study of 488 patients with non-severe COVID-19 and serum uric acid level ≤7 mg/dL at admission was conducted. Serum C-reactive protein (CRP), serum Krebs von den Lungen 6 (KL-6), and plasma D-dimer levels were also measured as markers of inflammation, alveolar damage, and coagulation abnormality, respectively. Median values for uric acid, CRP, KL-6, and D-dimer at admission were 4.4 mg/dL, 3.33 mg/dL, 252.0 U/mL, and 0.8 µg/mL, respectively. Among the total cohort, 95 (19.5%) progressed to severe COVID-19 with a median (interquartile range) time of 7 (4-14) days. Multivariable Cox proportional hazards regression analysis showed that low uric acid level was associated with a higher rate of severe COVID-19 progression. However, uric acid level was inversely associated with CRP level, and the association between the level of uric acid and severe COVID-19 progression was significantly different with and without CRP level inclusion. In contrast, no such association was found for KL-6 or D-dimer level. Low uric acid may contribute to severe COVID-19 progression via increased inflammation in subjects without hyperuricemia.

Longitudinal uric acid has nonlinear association with kidney failure and mortality in chronic kidney disease

We investigated the shape of the relationship between longitudinal uric acid (UA) and the hazard of kidney failure and death in chronic kidney disease (CKD) patients, and attempted to identify thresholds associated with increased hazards. We included CKD stage 3–5 patients from the CKD-REIN cohort with one serum UA measurement at cohort entry. We used cause-specific multivariate Cox models including a spline function of current values of UA (cUA), estimated from a separate linear mixed model. We followed 2781 patients (66% men, median age, 69 years) for a median of 3.2 years with a median of five longitudinal UA measures per patient. The hazard of kidney failure increased with increasing cUA, with a plateau between 6 and 10 mg/dl and a sharp increase above 11 mg/dl. The hazard of death had a U-shape relationship with cUA, with a hazard twice higher for 3 or 11 mg/dl, compared to 5 mg/dl. In CKD patients, our results indicate that UA above 10 mg/dl is a strong risk marker for kidney failure and death and that low UA levels below 5 mg/dl are associated with death before kidney failure.

Gout: A Case Report

Gout is a common clinical condition, usually seen with typical manifestations of swelling, erythema, tophi, and heat at joint(s). However, in rare circumstances, gout can present atypically, and it is important to recognize and manage it with appropriate medical therapy. This case study dives into a particularly atypical presentation of tophaceous gout in a patient with numerous comorbidities that complicate management. Visually appreciating the tophi, in this case, allows one to get an idea of their distribution on the digits, their unique chalky-white appearance, and how the presentation changed after therapy was initiated. Additionally, learning about the in-depth management and step-wise escalation of treatment is a crucial takeaway from this case, especially in the backdrop of the patient’s CKD3b and CHF - making selecting pharmacotherapy a challenge. After some trial and co-consultation with nephrology, the final effective treatment course for this patient involved using a combination of Allopurinol and Pegloticase (Krystexxa) together; this provided both a clinical improvement and a decrease in lab values of uric acid, dropping from 11.4mg/dL at peak to 4.4mg/dL.

Uric acid is independently associated with interleukin-1β levels in tear fluid of hyperuricemia and gout patients.

To explore pro-inflammatory cytokines status in the tear fluid of patients with hyperuricemia and gout and its association with uric acid level. A total of 58 control subjects, 58 hyperuricemia patients including 40 asymptomatic hyperuricemia and 18 gout participants were recruited in this study. For tear analysis, each patient's tears were collected using capillary action microcaps after stimulation. Tear uric acid levels were measured using chemiluminescence. Tear and serum interleukin-1beta (IL-1β) and tumor necrosis factor-alpha (TNF-α) levels were measured using enzyme-linked immunosorbent assay. The correlation of serum and tear uric acid levels with IL-1β and TNF-α were determined. Tear uric acid levels were significantly higher in hyperuricemia group (98.2 ± 51.5vs. 42.7 ± 24.0 µmol/L, p < .001) than in controls group. IL-1β concentrations were significantly higher in hyperuricemia eyes compared to control eyes (210.2 ± 113.9vs. 142.6 ± 29.8 pg/mL, p < .001). Multiple linear regression analysis showed that tear uric acid levels were independently positively associated with tear IL-1β concentrations (B = 0.192, p < .001). However, no significant correlations were found between serum or tear uric acid and TNF-α level. Moreover, there were no statistically differences of tear IL-1β and TNF-α levels between the asymptomatic hyperuricemia and gout groups. Tear uric acid levels were higher in patients with hyperuricemia and gout than in controls. There was a significant positive correlation between tear uric acid value and tear IL-1β level, implying an interaction between hyperuricemia and ocular inflammation responses.

The Inter-Trimester Variation and Prognostic Value of Creatinine, Cystatin C and Uric Acid in Preeclamptic Patients: A Retrospective Study

Background: This study aimed to evaluate the clinical significance of maternal serum creatinine, cystatin C, and uric acid levels in relation to fetal death in pregnant women with preeclampsia. Methods: This retrospective study evaluated 708 women with preeclampsia, and 738 healthy pregnant women were selected as control. Medical records were reviewed to collect obstetric, neonatal, and biochemical data, including creatinine, cystatin C, and uric acid concentrations. Results: Maternal serum creatinine, cystatin C, and uric acid concentrations were significantly higher in the preeclamptic group than in the control (p &lt; 0.05). Preeclamptic women in the fetal death group had significantly higher creatinine levels during their second and third trimesters, and higher uric acid concentrations throughout the pregnancy compared to the fetal survival group. Preeclamptic patients were divided into four groups based on quartiles of uric acid levels. The overall fetal survival rate in patients with upper-quartile uric acid concentrations was significantly lower than those with low uric acid levels during pregnancy. Multivariate logistic regression analysis revealed that uric acid concentration was a significant risk factor for fetal death in the first and second trimesters in the preeclamptic group (p &lt; 0.05). Conclusions: In pregnant women with preeclampsia, fetal death was associated with upper-quartile uric acid concentrations in the first and second trimesters. Uric acid levels can be an indicator of fetal death in the early and middle stage of pregnancy.

Prediction of STN-DBS for Parkinson's disease by uric acid-related brain function connectivity: A machine learning study based on resting state function MRI.

Parkinson's disease (PD) is a neurodegenerative disorder characterized by dyskinesia and is closely related to oxidative stress. Uric acid (UA) is a natural antioxidant found in the body. Previous studies have shown that UA has played an important role in the development and development of PD and is an important biomarker. Subthalamic nucleus deep brain stimulation (STN-DBS) is a common treatment for PD. Based on resting state function MRI (rs-fMRI), the relationship between UA-related brain function connectivity (FC) and STN-DBS outcomes in PD patients was studied. We use UA and DC values from different brain regions to build the FC characteristics and then use the SVR model to predict the outcome of the operation. The results show that PD patients with UA-related FCs are closely related to STN-DBS efficacy and can be used to predict prognosis. A machine learning model based on UA-related FC was successfully developed for PD patients. The two biomarkers, UA and rs-fMRI, were combined to predict the prognosis of STN-DBS in treating PD. Neurosurgeons are provided with effective tools to screen the best candidate and predict the prognosis of the patient.

Hacking techniques improve health and nutritional status of nestling White-tailed Eagles.

Birds of prey frequently feature in reintroductions and the hacking technique is typically used. Hacking involves removing large nestlings from donor populations, transferring them to captivity, feeding them ad libitum. Potentially, via the hacking method, the stress of captivity and disruption of parental feeding may be detrimental. Alternatively, the provision of ad libitum food may be advantageous. Although hacking has underpinned reintroduction project successes there has been no research on how the method may affect the health and nutritional status of translocated birds during captivity. We compared blood chemistry data from 55 young White-tailed Eagles, translocated from Norway as part of the species' reintroduction to Scotland, from sampling soon after arriving in captivity and again (≈42 days later) before their release. Numerous significant differences between the first and second samples were found, but no significant interactions showed that the sexes responded similarly to captivity. According to hematological and biochemical metrics, individuals showed several changes during captivity, including in red blood cell parameters, plasma proteins, and white cellular parameters related to the immune system, that indicated improved health status. Captivity with ad libitum food was associated with decreased urea and uric acid values: high values can indicate nutritional stress. Urea values became more normally distributed before release, indicating that ad libitum food had reduced nutritional differences between early nestlings in the season and later ones. Despite plentiful food, both sexes lost body mass before release, suggesting an inherent physiological mechanism to improve flight performance in fledglings. We conclude that hacking improved the health and nutritional status of released eagles which is likely to enable birds to cope with greater costs of exploratory behavior which they may require in reintroduction projects. In this context, we note the absence of survival differences between hacked and wild raptors in previous research.

Comparison of 24-hour urine composition prior to and after stone removal in nephrolithiasis: a prospective observational study.

To evaluate 24-hour urine composition prior to and after complete stone removal in nephrolithiasis patients to determine potential relationship between kidney stones and patient metabolic status. A prospective observational study was performed with patient enrollment from March 2019 to August 2020. 24-hour urine samples were collected prior to stone removal and 4 weeks after double-J stent removal, and examined the following urinary parameters: volume, creatinine, sodium, calcium, uric acid, citrate, oxalate, potassium, phosphorous, magnesium, and pH value. For each parameter, pairwise t test was performed to compare samples prior to and after stone removal. The number of cases that changed from normal to abnormal or vice versa was also evaluated for each parameter. The study was registered at http://clinicaltrials.gov/ (NCT03846011). A total of 109 patients completed 24-hour urine collections prior to and after stone removal. The urinary calcium and phosphate levels increased significantly after stone removal, showing a mean difference of 0.55 mmol (P=0.015) and 2.35 mmol (P=0.001) respectively. None of the other urinary parameters demonstrated a statistically significant difference when means were compared. The percentage differences for all urinary parameters ranged from 5.4% to 14.1%. The percentages of patients that presented clinically significant changes in urinary parameter values from normal to abnormal or vice versa ranged from 4.6% to 20.1%. Ideally, evaluation of 24-hour urine compositions should be undertaken after total stone removal, especially for patients with calcium stones. For patients who cannot achieve total stone removal, 24-hour urine samples should be thoroughly interpreted as urinary calcium and phosphate levels might be depleted in the presence of urinary stones.

Evaluation of Uric Acid and Its Correlation with Decline in Estimated Glomerular Filtration Rate among the Chronic Kidney Disease Patients

Chronic kidney disease is one of the most serious public health burdens globally, with significant morbidity, mortality, and compromise patient life expectancy. Many sub-Saharan African countries face double-burden challenges in the treating of chronic kidney disease and its associated complications. The current study aims to evaluate serum uric acid, and its correlation with estimated glomerular filtration rate as well as other risk factors among the chronic kidney disease patients on follow-up at renal clinic of Jimma University specialized referral hospital. An Institution-based cross-sectional study was conducted at Jimma University referral from August 6, 2022, to November 13, 2022. A consecutive sampling technique was employed to recruit the study participants into the current study. Data were collected using interviewer-based structured questionnaires and patient’s record reviews. The collected data were analyzed by SPSS version 25.0. Pearson’s correlation analyses was used to check the correlation between estimated glomerular filtration rate and uric acid. Univariate and multivariate linear regression model was used to test predictors of serum uric acid in the study participants. The total study participants were 140 individuals. Subjects included (54.3% [n=76]) men and (45.7% [n=64]) women, respectively. The mean (SD) age of study subjects was 51.04±9.02 years. The mean value of serum uric acid was 7.2±2.1mg/dl whereas the mean of estimated glomerular filtration rate (eGFR) was 54.2±31 mL/min/1.73m². Furthermore, the mean values of serum creatinine and blood urea nitrogen among participants in this study were 3.2±1.4 and 67.8±35.8 mg/dL respectively. In the current study, estimated glomerular filtration rate (eGFR) value was negatively correlated (r=-0.912, P<0.001) with uric acid. However, systolic blood pressure was positively correlated (r=0.584, P<0.001) with uric acid. Moreover, the eGFR value was negatively associated (β=-0.060, P=<0.001) with uric acid among study participants. Based on the current study finding, an increase in serum uric acid was associated with a decrease in eGFR value. Increased serum uric acid, increased body mass index and high blood pressure are independent risk factors for disease progression in patients with CKD.

Clinical and Biological Data in Patients with Pancreatic Cancer vs. Chronic Pancreatitis-A Single Center Comparative Analysis.

In some patients with chronic pancreatitis, the diagnosis of pancreatic cancer can be missed. The objective of the study was to identify clinical and paraclinical data with statistical significance in the differential diagnosis between chronic pancreatitis and pancreatic cancer. We conducted a retrospective, observational study on a cohort of 120 patients hospitalized over 3 years. The patients were equally distributed in two groups: group A, with 60 patients with pancreatic cancer, and group B, with 60 patients with chronic pancreatitis. The statistical analysis was carried out by using the R program. The comparative analysis of pancreatic cancer vs. chronic pancreatitis revealed a stronger link between pancreatic cancer, female gender (p = 0.001) and age over 60 years (p < 0.001). Patients with pancreatic cancer had higher serum values of aspartate aminotransferase (p 0.005), alanine aminotransferase (p 0.006), total bilirubin (p < 0.001), direct bilirubin (p < 0.001), alkaline phosphatase (p 0.030), C-reactive protein (p = 0.049) and uric acid (p 0.001), while patients with chronic pancreatitis presented slightly higher values of amylase (p 0.020) and lipase (p 0.029). Female gender, advanced age, elevated aminotransferases, cholestasis markers and uric acid were associated with a higher probability of pancreatic cancer.

Correlation Analysis between Uric Acid and Metabolic Syndrome in the Chinese Elderly Population: A Cross-Sectional Study.

Currently, both metabolic syndrome and hyperuricaemia have attracted extensive attention in public health. The correlation between uric acid and metabolic syndrome is controversial. Research on the relationship between uric acid and metabolic syndrome in community-dwelling elderly people is relatively lacking. The purpose of this study is to explore the relationship between uric acid and metabolic syndrome in the community-dwelling elderly people. Cross-sectional study. We collected the physical examination data of 1,267 elderly people in Gutian community in Wuhan and used SPSS IBM 25.0 for data analysis. Correlation and logistic regression analyses were performed, and ROC curves were drawn. The uric acid level of the nonmetabolic syndrome group was lower than that of the metabolic syndrome group (337.31 vs. 381.91 µmol/L; P < 0.05). Uric acid was positively correlated with systolic blood pressure (r = 0.177, P < 0.001), diastolic blood pressure (r = 0.135, P < 0.001), body mass index (r = 0.234, P < 0.001), waist circumference (r = 0.283, P < 0.001), and triglycerides (r = 0.217, P < 0.05). High-density lipoprotein cholesterol (r = -0.268, P < 0.001) showed the opposite trend. Logistic regression analysis results suggested that uric acid is a risk factor for metabolic syndrome. The result is described as exp (B) and 95% CI (1.003 [1.001, 1.005]). Based on the receiver operating characteristic curve, we found that the area under the curve of uric acid to diagnose metabolic syndrome was 0.64 (sensitivity: 79.3%, specificity: 45.1%). We observed an association between uric acid levels and metabolic syndrome in the elderly Chinese population. The best threshold value for uric acid in predicting metabolic syndrome diagnosis was 314.5 μmol/l.
