Prevalence of Hypovitaminosis D and its Association with Serum Lipids in Patients with Type 2 Diabetes Mellitus

Background Hypovitaminosis D has become worldwide public health concern affecting all age groups and both genders. Its prevalence is very high in South Asia. Many studies reported that vitamin D deficiency is concerned with diabetes mellitus and impaired glucose tolerance. The aim of this research was to find the prevalence of hypovitaminosis D and its association with serum lipids among type 2 diabetic patients.MethodsA cross-sectional study, conducted among a total 162 patients with type 2 diabetes mellitus in Manipal Teaching Hospital, Pokhara. The serum level of FBS, PPBS, urea, creatinine, calcium and phosphorus, HbA1c, TG, TC, HDL-C, and vitamin D levels were measured. In the descriptive categorical data were reported in frequency with percentage and numerical data were presented as mean±SD while in inferential statistics to compare the value student t-test were used. p-value<0.05 was considered as statistically significant.ResultsThe mean±SD serum level of vitamin D was 24.48 ± 13.21 ng/mL in patients with type 2 diabetes. The prevalence of hypovitaminosis D was 69.14% (With 95% CI as 62.02 to 76.25%) and sufficient of vitamin D in 30.86% (With 95% CI as 23.74% to 37.97%) among patients with type 2 diabetes. The serum lipids showed statistically insignificant association between hypovitaminosis D with sufficient of vitamin D.Conclusions This research showed that only in one third of the patients had Vitamin D sufficiency. The serum lipids were slightly increased in patients who had hypovitaminosis D.

Potential nephroprotective effect of dapagliflozin against renal ischemia reperfusion injury in rats via activation of autophagy pathway and inhibition of inflammation, oxidative stress and apoptosis

Renal ischemia/reperfusion injury is a common cause of acute kidney injury (AKI), causing tissue damage, inflammation and oxidative stress. Autophagy, responsible for breakdown and recycling of cytoplasmic components. In hypoxic and ischemic renal damage, autophagy may serve as a survival strategy for the cells. Dapagliflozin has been shown to have protective effects against ischemia. Objective: The study investigates the potential nephro-protective effects of dapagliflozin on renal ischemia reperfusion injury, evaluating its antioxidant, anti-inflammatory, anti-apoptotic effects and activation of autophagy via biochemical parameters and histopathological changes in adult male rats. Material and method: In this study, twenty eight male rats weighing between 200-300g, were divided into 4 groups sham, RIRI, DMSO, Dapagliflozin pretreated groups. All groups subjected to 30 min. of ischemia then 24 h of reperfusion except sham undergo the same anesthesia and surgical procedures except for bilateral renal ischemia. Dapagliflozin 1mg/kg and DMSO was given 2 hours before the induction of ischemia. Results: The study found that blood urea and serum creatinine levels increased in RIRI and DMSO groups when compared with sham group. Renal tissue levels of IL-6, Kim-1, caspase-3, LC-3 and Akt were also elevated in RIRI while GSH levels decreased in the RIRI. Dapagliflozin group showed significant increases in GSH, LC-3 and Akt levels when compared to sham group. Dapagliflozin reduced serum urea and creatinine levels, and renal tissue levels of IL-6, Kim-1, and caspase-3 also reduced. Conclusion: Dapagliflozin significantly reduced renal damage in rat model due to its antioxidant, anti-inflammatory, anti-apoptotic, and activation autophagy.

Effect of Incorporating Soursop (Annona muricata) Leaves Powder on Reproductive Performance of Japanese Quail (Coturnix coturnix japonica)

Introduction: Soursop leaves are rich in various molecules, including total phenols, terpenes, and steroids, which possess a range of pharmacological properties that can be utilized in animal production to enhance both growth and reproduction of animals. The present study aimed to evaluate the effect of incorporating soursop (Annona muricata; A. muricata) leaves powder into feed on the reproductive performance of Japanese quail. Materials and methods: A total of 80 Japanese quails (64 females and 16 males) aged two weeks were randomly divided into four experimental groups, labeled T0, T1, T2, and T3, and received feed additives with 0 mg/kg body weight (bw), 250 mg/kg bw, 500 mg/kg bw, and 750 mg/kg bw of powdered soursop leaves, respectively. Additionally, water was provided ad libitum, and the quails' weights were measured every 7 days for a period of 75 days. At the end of the period, 12 female quails from each group were sacrificed after 24 hours fasting period. Blood was collected for hematological (Leukocyte, Erythrocyte, and Platelet indices) and serum biochemical (total serum cholesterol, total proteins, albumin, and globulin, Aspartate aminotransferase, Alanine aminotransferase, Urea, and Creatinine) analysis. The males were also sacrificed to evaluate the spermatozoa characteristics (mobility, concentration, and viability). Results: No statistical significant changes in growth characteristics or hematological parameters were observed. However, biochemical parameters increased significantly with the inclusion of Soursop (A. muricate) in quail feed, including increased total cholesterol, total protein, and globulin levels, and decreased malondialdehyde levels. This effect was most significant at dosage of 500 mg/kg bw. Serum levels of urea, Alanine aminotransferase, and Aspartate aminotransferase were not significantly affected by A. muricata whatever the concentration considered. A significant increase in fast progressive spermatozoa, along with a decrease in immotile spermatozoa, was observed with A. muricate at dosage of 500 mg/kg bw compared to the control. Sperm viability also increased significantly, particularly in live at dosage of 500 mg/kg bw. Significant increase was observed in fertility parameters, including increased fertility rate, hatchability rate of fertile eggs, total hatchability rate, and chick weight, along with decreased embryonic mortality at 500 mg/kg bw treatment compared to the control. Conclusion: In conclusion, the findings indicated that incorporating A. muricata leaf powder at 500 mg/kg bw into quail feed positively influences reproductive cells and boosts fertility growth promoters.

Potential benefit of Lactobacillus acidophilus supplementation to rats fed with a high-fat diet on serum lipid profile, kidney amyloid protein and tumor necrosis factor-alpha level

AimIt was aimed to determine the potential effect of Lactobacillus acidophilus supplementation on rats exposed to an experimental high-fat diet on serum lipid profile and kidney total beta amyloid protein (TBAP) and Tumor Necrosis Factor-alpha (TNF-α) levels. Methods24 male Sprague-Dawley rats were used in the study to establish 4 groups. Standard rat food (SD) was provided to Group 1 as the control; Group 2 was fed a high-fat diet (HFD); Group 3 consumed SD and received L. acidophilus probiotics; Group 4 was fed HFD and received L. acidophilus probiotics. Body weights were determined weekly during the 12-week trial period. At the end of the experiment, TBP and TNF-α levels in the serum and kidney tissue of the rats were measured by ELISA method. Serum total cholesterol (TC), triglyceride (TG), HDL, LDL, urea and creatinine levels and paraoxanase, amylase and lipase activities were determined by spectrophotometric method on the analyzer device. ResultsWhen the control (Group 1) group and Group 2 were compared at the end of the experiment, it was found that Group 2 had gained the most weight and that both the blood and kidney tissue levels of TNF-α and TBAP, as well as the quantities of TG, TK, LDL, and urea, were significantly greater (P<0.05). Serum HDL, PON and amylase levels were found to be significantly low (P>0.05). TG, TK, LDL, urea, and the levels of TNF-α and TBAP in serum and renal tissue were shown to be lower in the groups who received L. acidophilus probiotics (Groups 3, 4) when compared to Group 2 (P>0.05). It was observed that HDL, PON and amylase levels increased and approached the control group (P<0.05). ConclusionThe study's findings showed that probiotic supplementation improved blood levels of TG, TC, HDL, LDL, urea, PON, and amylase as well as serum and kidney tissue levels of TNF-α and TBAP in obese rats fed a high-fat diet.

EGCG alleviates Ochratoxin A-induced pyroptosis in rat's kidney by inhibiting NLRP3/Caspase-1/GSDMD signaling pathway

Ochratoxin A (OTA) exposure is inevitable due to its contamination in foods, and there is no treatment for the OTA induced organ toxicity. We evaluate the effect of epigallocatechin gallate (EGCG) on the nephrotoxicity caused by OTA, and to reveal the relationship of this effect with the NLRP3/Caspase-1/GSDMD pathway dependent pyroptosis. 40 male Wistar albino rats divided into 5 groups (n = 8, per group) 0.5 mg/kg/day OTA were administered to the rats and 50 mg/kg and 100 mg/kg EGCG were administered to the groups by gavage orally for 14 days. Serum urea and creatinine levels increased significantly with OTA exposure. Similarly, it was determined that significant changes in oxidative stress parameters with OTA exposure in kidney tissue. Also, there was a significant increase in kidney tissue TGF-β, NF-κB, IL-1β, IL-18, NLRP3, Caspase-1 and GSDMD mRNA expressions with OTA exposure. EGCG administration augmented a dose-dependent decrease in the aforementioned parameters. NLRP3/Caspase-1/GSDMD pathway is induced in the kidneys due to OTA exposure were shown with this study. Potent antioxidant EGCG could alleviate the pathways specified with this study in OTA nephrotoxicity and its supplementation may be effective strategies for the protection.

Geniposidic Acid Attenuates Chronic Tubulointerstitial Nephropathy Through Regulation of the NF-ƙB/Nrf2 Pathway Via Aryl Hydrocarbon Receptor Signaling.

Renal fibrosis is an outcome of chronic kidney disease, independent of the underlying etiology. Renal fibrosis is caused primarily by oxidative stress and inflammation. We identified the components of Plantaginis semen and elucidated their anti-fibrotic and anti-inflammatory mechanisms. The renoprotective components and underlying molecular mechanisms of P. semen were investigated in rats with adenine-induced chronic tubulointerstitial nephropathy (TIN) and in idole-3-acetic acid (IAA)-stimulated NRK-52E cells. Acetate and n-butanol extracts were found to be the bioactive fractions of P. semen. A total of 65 compounds including geniposidic acid (GPA), apigenin (APG), and acteoside (ATS) were isolated and identified. Among the seven main extract components, treatment with GPA, APG, and ATS reduced the serum levels of creatinine and urea in TIN rats. Mechanistically, GPA ameliorated renal fibrosis through repressing aryl hydrocarbon receptor (AHR) signaling and regulating redox signaling including inhibiting proinflammatory nuclear factor kappa B (NF-ƙB) and its target gene products as well as activated antioxidative nuclear factor-erythroid-2-related factor 2 (Nrf2) and its downstream target gene products in both TIN rats and IAA-stimulated NRK-52E cells. The inhibitory effect of GPA on AHR, NF-Ƙb, and Nrf2 signaling were partially abolished in IAA-stimulated NRK-52E cells treated with CH223191 compared with untreated IAA-stimulated NRK-52E cells. These data demonstrated that GPA alleviates oxidative stress and inflammation partly by suppressing AHR signaling.

Association of Therapeutic Monitoring of Tacrolimus with Laboratory Markers of Kidney Function in Receptors of Kidney Allograft

Introduction: Kidney transplantation is the most commonly performed type of transplant in Brazil. Tacrolimus is one of the primary drugs used in post-transplant immunosuppressive therapy, and one of its main adverse effects is nephrotoxicity. Laboratory tests to assess renal function are of great importance in monitoring post-kidney transplant patients, helping to diagnose events indicative of graft dysfunction. Objective: !e present study aimed to evaluate the association between laboratory changes in renal function and blood levels of tacrolimus in post-kidney transplant patients. Methods: Observational, analytical and cross-sectional study. !e results of blood levels of tacrolimus and measurements of urea, creatinine and estimated Glomerular Filtration Rate (eGFR) were analyzed, as well as the sociodemographic data of kidney transplant recipients followed at a university hospital who underwent laboratory tests between months from January 2021 to July 2022 in a period close to 1 year after the transplant. !e variables analyzed in the research were collected from the patient's medical records and subsequently analyzed; the statistical analyses considered p &lt; 0.05. !e project was approved by the Ethics Committee of the Walter Cantídio University Hospital under opinion number 5,436,434 and CAAE number 57396622.1.0000.5045. Results: !e sample was mainly composed of males, mixed race, with an average age of 51.5 years (SD ± 12.5) and from cities in the interior of Ceará. Regarding the percentage of patients with laboratory changes, 50.62% (n = 45) showed changes in tacrolimus blood levels. 56.79% (n = 46) had changes in serum creatinine levels, 49.38% (n = 40) had changes in serum urea levels, and 59.26% (n = 48) had altered eGFR. !e correlation analyses suggested a low signi#cance between variations of the variables studied. Conclusion: !e results indicate no relationship between variations in tacrolimus blood concentrations and the appearance of changes in the results of classic renal biomarkers at the end of the #rst year post-transplant. However, it is necessary to carry out new studies to understand better the impact of changes in blood levels of tacrolimus on the renal function of renal allograft recipients.

Long-Term Survival of Patient with End-Stage Renal Disease Using Bayesian Mixture Cure Rate Frailty Models.

Along with the increasing prevalence of ESRD in developing countries, the use of more up-to-date statistical models is highly recommended. It is crucial to control potential cure pattern and heterogenicity among patients. In this longitudinal study, the data of 170 hemodialysis patients who visited the dialysis department of Shafa Hospital in Kerman from 2006 to 2016 were collected. To provides robust estimates the time to event data (death) were analyzed with a gamma frailty mixed cure Weibull model (MC-WG) using Bayesian inference. About 49% of patients experienced the death and median survival time was 37.5 months. Older patients (0.264), female patients (0.269), and patients with higher mean serum urea levels (0.186) had a higher risk of death. Moreover, we observe a decrease in death with increase in Creatine (Cr). In the MC-WG Bayesian model, the diabetes, AST, calcium, phosphorus and uric acid variables had a significant effect on the survival of hemodialysis patients, while they were not significant in the Cox PH model. The results of MC-WG Bayesian model are more consistent with other studies.

Establishment and validation of a clinical risk scoring model to predict fatal risk in SFTS hospitalized patients

BackgroundSevere fever with thrombocytopenia syndrome (SFTS) is an emerging tick-borne infection with a high case fatality rate. Significant gaps remain in studies analyzing the clinical characteristics of fatal cases.MethodsFrom January 2017 to June 2023, 427 SFTS cases were included in this study. A total of 67 variables about their demographic, clinical, and laboratory data were collected. Univariate logistic regression and the least absolute shrinkage and selection operator (LASSO) method was used to screen predictors from the cohort. Multivariate logistic regression was used to identify independent predictors and nomograms were developed. Calibration, decision curves and area under the curve (AUC) were used to assess model performance.ResultsThe multivariate logistic regression analysis screened out the four most significant factors, including age > 70 years (p = 0.001, OR = 2.516, 95% CI 1.452–4.360), elevated serum PT (p < 0.001, OR = 1.383, 95% CI 1.143–1.673), high viral load (p < 0. 001, OR = 1.496, 95% CI 1.290–1.735) and high level of serum urea (> 8.0 μmol/L) (p < 0.001, OR = 4.433, 95% CI 1.888–10.409). The AUC of the nomogram based on these four factors was 0.813 (95% CI, 0.758–0.868). The bootstrap resampling internal validation model performed well, and decision curve analysis indicated a high net benefit.ConclusionsThe nomogram based on age, elevated PT, high serum urea level, and high viral load can be used to help early identification of SFTS patients at risk of fatality.

Assessment of Biochemical Potential of Rhizopus oligosporus as Starter Culture to Enhance the Nutritional Value of Palm Kernel Cake for Animal Feed Formulation

The objective of this study was to assess the biochemical potential of Rhizopus oligosporus as a starter culture to enhance the nutritional value of palm kernel cake (PKC) for animal feed formulation using appropriate standard methods. Among the experimental groups, the batch of birds fed with solid-state fermented PKC as a 50% maize replacement showed a noteworthy weight gain (p &lt; 0.05) in relation to the control group, while the other experimental groups exhibited a weight loss. Serum levels of ALT, AST, ALP, creatinine, and blood urea did not show a notable difference from the reference group and those on the experimental diets. These findings collectively suggest that the pre-treatment of PKC using R. oligosporus holds the potential to elevate its nutritional quality for utilization in animal feed applications.

Plasma activated water effects on behavior, performance, carcass quality, biochemical changes, and histopathological alterations in quail

BackgroundPlasma-activated water (PAW) is an innovative promising technology which could be applied to improve poultry health. The current study investigated the effects of drinking water supply with PAW on quail behaviour, performance, biochemical parameters, carcass quality, intestinal microbial populations, and internal organs histopathology. A total of 54 twenty-one-day-old Japanese quail chicks were randomly allotted to three treatments provided with PAW at doses 0, 1 ml (PAW-1), and 2 ml (PAW-2) per one litter drinking water. Each treatment contained 6 replicates (3 birds/ cage; one male and two females).ResultsThe results clarified that there were no significant (P > 0.05) changes in behaviour, and performance. For the biochemical indicators, the PAW-1 group showed significantly higher serum H2O2, total protein and globulin levels compared with the other groups (P = 0.015, < 0.001, and 0.019; respectively). PAW groups had significantly lower serum creatinine and urea levels than the control (P = 0.003). For the carcass quality, the internal organs relative weight between different treatments was not changed. In contrast, there was a significant increase in the meat colour, taste, and overall acceptance scores in PAW groups compared with the control one (P = 0.013, 0.001, and < 0.001; respectively). For the intestinal microbial population, lactobacilli count was significantly higher in PAW-2 compared with the control group (P = 0.014), while there were no changes in the total bacterial count between different treatment groups. Moreover, mild histological changes were recorded in the intestine, liver, and spleen of PAW groups especially PAW-2 compared with the control one.ConclusionsPAW offered benefits, such as reducing creatine and urea levels, improving meat characteristics, and increasing lactobacilli count, all of which are crucial for sustainable quail farming. Therefore, further research is needed.

Impacts of gentamycin toxicity: nephroprotective role of guarana through different signaling pathways.

Gentamicin is a widely used aminoglycosidic antibiotic since its discovery. Like any other medication gentamicin causes unwanted side effects such as hepatotoxicity and nephrotoxicity. This study aims to examine the antioxidant effect of the guarana seed extract in protecting renal tissue. Forty male mice were divided into four groups (group one was control with free access to food and water, group two was treated orally with 300mg/kg of guarana seed extract daily, group three was injected intraperitoneally with 100mg/kg of gentamicin daily and the fourth group was co-treated with both 300mg/kg of guarana seed extract orally and injected intraperitoneally with 100mg/kg of gentamicin daily) for two weeks. Serum levels of urea, creatinine, AST, ALT, IL-1β and IL-6 have significantly elevated in the gentamicin treated group and those changes were not found in the guarana co-treated group. In gentamicin treated mice, a significant reduction was observed in two antioxidants SOD and GPX accompanied by downregulation of Ho-1 and Nrf2 while, that did not happen in the guarana seed extract co-treated group. Histopathology and immunohistochemistry slides show that the guarana seed extract prevents degenerative and necrotic events in tubular epithelial tissues caused by gentamicin toxicity. In conclusion, current data suggest that gentamicin can damage renal tissues when given at 100mg/kg/day, however, the guarana seed extract may be capable of preventing that event when cotreated with the gentamicin as a supplement.

Correlation between salivary and serum biomarkers of kidney function in chronic kidney disease patients attending the nephrology clinics at Teaching Hospital Karapitiya, Sri Lanka

The present study was designed to determine the correlation between salivary and serum levels of creatinine and urea in patients with chronic kidney disease (CKD) and to propose the use of saliva as an alternative medium for the analysis of biochemical parameters of kidney function. Accordingly, an analytical cross-sectional study was carried out using 100 CKD patients attending the Nephrology Clinics at Teaching Hospital Karapitiya, Sri Lanka. Saliva and serum samples were collected from the patients for the estimation of creatinine and urea using spectrophotometric assay kits. Of the total, the majority of the patients were found within CKD stage 3 (82%). The salivary and serum concentrations of creatinine varied within the range of 0.20 - 2.10 mg/dL and 1.54 – 11.6 mg/dL, whereas the salivary and serum concentrations of urea varied within the range of 68.04 – 127.59 mg/dL and 60.14 – 168.25 mg/dL respectively within the study population. Significant positive correlations were observed between the salivary and serum concentrations of creatinine (r= 0.985, p=0.01), and urea (r= 0.942, p=0.01), and between salivary concentrations of creatinine and urea (r=0.887, p=0.01). A significant difference was observed in the salivary biomarkers between mild to moderate stages of CKD patients and severe to end-stage CKD patients. No significant association was observed in the salivary markers with the age and sex of the patients. The area under curve values in the receiver operating characteristic analysis was&gt;0.9 (95% CI). These findings revealed high levels of diagnostic accuracy in salivary biomarkers suggesting the potential use of saliva for the assessment of kidney function in CKD patients.

Biologically Synthesized Gold Nanoparticles Mitigate Aluminum Chloride-Induced Nephrotoxicity via Downregulation of iNOX, LCN2 and IL-1β Genes.

Humans are constantly exposed to aluminum (Al), an environmental toxicant, and its accumulation in the glomerular could lead to acute kidney disease. Biologically synthesized gold nanoparticles (AuNPs) have been employed in the management of kidney disorders. This study assessed the modulatory effect of AuNPs mediated by Hibiscus sabdariffa (HS) on aluminum chloride (AlCl3)-induced nephrotoxicity in rats. Experimental rats were randomly distributed into six groups of seven animals each. Aluminum chloride (100 mg/kg bw) was orally given to the rats for 42 days to induce nephrotoxicity. Treatment with silymarin and HS-AuNPs lasted for 14 days. Serum kidney function, tissue arginase level and oxidative stress biomarkers, as well as tissue gene expression of inducible nitric oxide synthase (iNOS), lipocalin 2 (LCN2) and interleukin-1 beta (IL-1β) were evaluated. Exposure of AlCl3 to the rats produced a marked (p < 0.05) increase in the levels of serum urea and creatinine in comparison with the control. Similarly, tissue arginase and malondialdehyde (MDA) levels were also increased while a reduction in the activity of superoxide dismutase (SOD) and the levels of reduced glutathione (GSH) and nitric oxide (NO) were noted in the AlCl3-induced rats. Aluminum chloride also upregulated the mRNA expression of iNOS, LCN2 and IL-1β in the rats. These biochemical alterations were, however, attenuated by the administration of HS-AuNPs but the 5 mg/kg HS-AuNPs exhibited better anti-nephrotoxic activity than the 10 mg/kg dose, and could, thus serve as a potential dose for managing renal diseases.

Association of Serum Uric Acid Level and Thyroid Function in Chronic Kidney Disease: A Hospital-Based Cross-Sectional Study From Northeast India.

Although the prevalence of thyroid dysfunction and hyperuricemia are independently high in patients with chronic kidney disease (CKD), there are limited data showing the association of serum uric acid and thyroid function in those with CKD. The aim of this study was to observe the alteration of both the serum uric acid level and thyroid function in CKD patients and to find the association between both. This observational cross-sectional study was conducted in a tertiary care hospital over a period of one year in Northeast India. A total of 50 CKD patients were enrolled. Their demographic profiles were studied. Serum urea, creatinine, thyroid-stimulating hormone (TSH), total triiodothyronine (TT3), free triiodothyronine (FT3), total tetraiodothyronine (TT4), and free tetraiodothyronine (FT4) levels were measured to establish the correlation of serum uric acid along with each of the parameters separately. A p-value of <0.05 was considered statistically significant. In the CKD patients studied, serum uric acid exhibited positive correlations with serum creatinine (p = 0.001, r = 0.67), serum urea (p = 0.001, r = 0.69), and serum TSH levels (p = 0.001, r = 0.5). Conversely, serum uric acid showed negative correlations with serum TT4 (p = 0.001, r = -0.74), TT3 (p = 0.001, r = -0.6), FT4 (p = 0.001, r = -0.53), and FT3 (p = 0.001, r = -0.58) levels. There was a significant positive correlation between uric acid and TSH levels in CKD patients. Thus, early estimation of both parameters should be considered in CKD patients.

Estimation of urea, uric acid and creatinine levels in patients of primary hypothyroidism - A cross-sectional study.

The thyroid gland is one of the largest endocrine glands in the body, secreting thyroxine (T4) and triiodothyronine (T3). Mild hypothyroidism can have negative consequences for a variety of tissues, even though clinically the patients are euthyroid. Many research studies were conducted to evaluate the serum creatinine levels of people with hypothyroidism; however, relatively little research was conducted to evaluate serum urea and serum creatinine levels in subclinical hypothyroidism. As a result, the current study was carried out to investigate urea, uric acid, and creatinine levels in hypothyroidism. Our study aimed to determine and correlate the levels of urea, uric acid and creatinine in newly diagnosed primary hypothyroidism cases. In this cross-sectional study, 96 newly diagnosed cases of primary hypothyroidism were included. The findings were correlated with 20-60-year-old and sex-matched cases. Serum urea was determined by the kinetic method (Glutamate Dehydrogenase Method), serum uric acid by the uricase method and serum creatinine by Jaffe's method in Erba's Mannheim fully automated analyser. This study showed a positive correlation between uric acid and thyroid stimulating hormone (TSH) and a negative correlation between urea and creatinine. There was no statistical significance in the mean values of urea, uric acid and creatinine but an increased level of urea, uric acid and creatinine was seen in the age group 20-30 years when compared with the other age groups. The study concludes that serum urea showed a positive correlation with TSH, whereas uric acid and creatinine showed a negative correlation with TSH, and there was no statistical significance in the mean values of urea, uric acid and creatinine in hypothyroid patients.

Evaluation of Hormonal and Biochemical Profile of Ladakhi Cow during Estrous Cycle: The Future Perspective of Reproductive Management of Ladakhi Cow

The Ladakhi cow is an indigenous breed from Ladakh, India, and has a unique genetic makeup to adapt to high-altitude hypobaric stress. Furthermore, little study is available on examining the Ladakhi cow’s blood biochemicals and reproductive hormonal status during various stages of the estrus cycle. Hence, the current study was conducted on eight reproductively mature Ladakhi cows at the experimental dairy cattle unit in Leh-Ladakh, India, to determine the changes in serum biochemical and hormonal levels during the estrus cycle. The estrus behaviour was initially observed before the blood sampling on days 0 (the day the cow exhibited heat symptoms), 2nd, 8th, 17th, and 21st days. The serum was isolated for biochemical and hormonal profiling as per standard procedures using commercially available kits. The results revealed that serum biochemicals, viz. Ca, Fe, ALT, AST, ALP, TG, TP, Albumin, Glucose, UA, Creatinine, and Urea levels were within the normal range of cows at high altitudes. However, reproductive hormones, e.g. GnRH, FSH, LH, progesterone, estrogen, PGF2α, IGF-1, and Insulin varied from the reference level at different stages of the estrus cycle. This study’s findings have provided new insights into the serum biochemical and hormonal profiling of Ladakhi cows during the estrus cycle and this information may help to develop a reference range and baseline value for the serum biochemicals and hormonal levels of Ladakhi cows for other breeding programs and health monitoring.

The potential role of dyslipidemia in COVID-19 severity among Iraqi patients.

The correlation between dyslipidemia and the severity of coronavirus disease 2019 has been widely categorized. Dyslipidemia is one of the most dominant disorders among these patients. Systemic inflammation accompanied by cytokine storm hemostasis modifications and severe vasculitis have all been reported to occur among COVID-19 patients, and these may contribute to some severe complications. The aim of this study is to assess the possible relationship between dyslipidemia and the severity of coronavirus disease 2019. This work encompassed 200patients with coronavirus disease 2019 (100dyslipidemic and 100normolipidemic) who were hospitalized at Baghdad Teaching Hospital/ Medical City-Baghdad, Iraq, from October 2021 to October 2022; their ages ranged between 40 and 55. Eligible individuals had a positive nasal swab polymerase chain reaction for severe acute respiratory syndrome coronavirus 2infection. Every participant's anthropometric and clinical features were measured. The study includes the measurements of glycemic, lipid profile, renal function test, D-dimer, C-reactive protein, serum ferritin, and interleukin-6 in dyslipidemic and normolipidemic groups. Considerable increase (p= 0.001) in glycemic and lipid levels in the dyslipidemic group compared to normolipidemic. Moreover, dyslipidemic patients have higher lipid indices (ratios) than the normolipidemic group. Significant increases (p= 0.001) in serum urea and creatinine levels were found among the dyslipidemic group compared to normolipidemic. There was a non-considerable decrease (p= 0.062) in serum total protein in the dyslipidemic group concerning the normolipidemic. In contrast, a considerable decrease (p= 0.045) in serum albumin was detected in the dyslipidemic group compared to normolipidemic. D-dimer, serum C-reactive protein, ferritin, and interleukin-6 were significantly increased (p= 0.001) in the dyslipidemic group compared to normolipidemic. Dyslipidemia potentially raises the severity of coronavirus disease 2019. There was a significant disturbance in renal function tests among coronavirus disease 2019patients. The study found a significant and statistical difference in kidney functions between dyslipidemic and normolipidemic groups. The patients, especially the dyslipidemic ones, have experienced protein abnormalities and a significant inflammation rate reflected by higher C-reactive protein and interleukin-6, which is due to the severity of coronavirus disease 2019. It is possible to conduct more research with a larger sample size. The majority of people who have dyslipidemia need to be enlightened.

The components of arginine and methylarginine metabolism are indicative of altered kidney function in intrauterine growth-restricted neonates.

Intrauterine fetal growth restriction (IUGR) affects up to 10% of all pregnancies. Severe IUGR is associated with impaired kidney development, reduced nephron endowment, and chronic kidney disease later in life. Currently, no early predictive biomarker exists for detecting altered kidney function in neonates with IUGR. Because nephrons produce key enzymes for the metabolism of arginine and methylarginine components, we quantified and compared the concentrations of arginine and methylarginine metabolites between IUGR and non-IUGR neonates to identify potential biomarkers for the early detection of altered kidney function in IUGR neonates. Seventy-one IUGR and 123 non IUGR neonates were examined. Serum and Urine samples were obtained between 30 h and 5 days of life and between 5 and 70 days of life. Serum concentrations of creatinine, urea, symmetric and asymmetric-dimethylarginine metabolites (SDGV, SDMA, ADGV, and ADMA), guanidino-2-oxo-caproic acid (GOCA), citrulline, homocitrulline, arginine, and homoarginine were quantified using LC-MS/MS and standard clinical laboratory methods. Datasets were compared by Mann-Whitney--Wilcoxon or Chi-square tests for continuous and discrete parameters. P values were corrected for multiple comparisons using the Bonferroni method. After Bonferroni correction, we found that serum creatinine, urea, SDGV, ADGV, and GOCA levels were significantly lower in neonates with IUGR. Consequently, the ratios of SDGV/SDMA, ADGV/ADMA, and GOCA/homoarginine were significantly lower in IUGR neonates. Our study suggests that arginine and methylarginine are possible early biomarkers for detecting altered kidney function in IUGR neonates.

Investigation of the thyroid function in end-stage renal failure disease in a Baquba teaching hospital/Diyala governorate - Iraq

Renal failure is the inability of the kidneys to excrete nitrogenous waste products, resulting in their retention in the bloodstream. Several correlations exist between renal and thyroid functions; however, end-stage renal failure is unlikely to be influenced by thyroid hormone function and is connected to a higher prevalence of hypothyroidism. The purpose of this study is to ascertain how thyroid status and renal function relate to renal failure patients. Serum creatinine and urea levels were tested in 50 healthy persons and 100 patients with renal failure illness. The acquired data showed that, in comparison to the control group, the average levels of creatinine and urea were significantly higher. The sick group recorded (122.98 mg/dL and 6.55 mg/dL) and (28.38 mg/dL and 0.75 mg/dL) in comparison to the control group, which has urea and creatinine values within the virtually normal range, respectively. In contrast, TSH levels showed no significant differences and have values within the normal range of TSH values, with 2.33 mIU/L for the experimental group and 2.0 mIU/L for the control group. In contrast, T4 values of the experimental group showed significantly lower levels than the control group, with 83.42 ng/dL compared to 103.77 ng/dL. T3 values, however, showed no significant changes and remained within the normal range of 1.75 to 1.64 nmol/L. In addition, the results demonstrated significant differences in the mean levels of anti-TPO, anti-Tg, and anti-TSHR antibodies. The anti-Tg showed a significant decrease in mean values, which were 28.89 IU/ml and 79.49 IU/ml compared to the control group ranges of 34.41 and 86.68 IU/mL. Finally, anti-TSHR showed a significant increase in the mean, which was 1.24 IU/L compared to 1.18 IU/L in the control group.
