Lipid profile in elderly and centenarian subjects in Kazakhstan: a case-control study

Introduction. The health of centenarians is a major focus in global studies. Dyslipidemia is directly linked to the risk of cardiovascular diseases, which pose a growing burden on healthcare due to the increasing elderly population. Studying the lipid profiles of centenarians is important for preventing circulatory system diseases and promoting healthy aging. This research aims to compare the prevalence of dyslipidemia in centenarians (median age 96 [95-97]) with elderly individuals (median age was 69 [64 – 74]) in the Republic of Kazakhstan and examine potential predictors of dyslipidemia in the centenarian group. Methods. The study involved 46 centenarians (study group) and 82 elderly individuals (control group). Statistical analysis was used to process the data, including blood markers and demographic variables, to identify factors contributing to dyslipidemia. Results and conclusion. The prevalence of hypercholesterolemia in centenarians was 32.6% (15 people - 3 men; 12 women), with elevated LDL levels in 4.3% (2 women). In the control group, hypercholesterolemia prevalence was 29.3% (24 people - 6 men; 18 women) and elevated triglycerides in 6.1% (3 women; 2 men). The study and control groups were compared based on their lipid profile characteristics, which showed similarities as indicated by all p-values being above 0.05: Cholesterol (p=0.348), HDL (p=0.975), LDL (p=0.161), and Triglycerides (p=0.159). Decreased physical activity was a predictor of dyslipidemia in centenarians. Excessive cholesterol levels were significantly higher among women than men in both groups. The primary factor for dyslipidemia was low physical activity, with other predictors having no significant impact on the lipid profiles of centenarians. This factor should be considered when assessing cardiovascular disease risks and all-cause mortality.

Evaluation of the Antihyperlipidemic Effect of Encapsulated Octacosanol for Lipid-Lowering Effect Against High-Fat Diet-Induced Hyperlipidaemia in Experimental Rats.

Background: Elevated blood lipid levels, or hyperlipidemia, are the main risk factors for cardiovascular illnesses and are frequently brought on by high-fat diets. Objectives: In this work, high-fat diet-induced hyperlipidemia in experimental rats is used to examine the antihyperlipidemic efficacy of a test formulation containing 1-octacosanol. Method: A healthy female Wistar rat was utilized for investigation, separated into four groups: normal, disease, standard control, and test group, receiving the 1-octacosanol formulation. Results: Hyperlipidemia was induced in the rats through a high-fat diet over 28 days, followed by a 28-day treatment period. Various parameters, including lipid profile (LDL, TC, TG, VLDL, HDL), body weight and antioxidant properties (MDA, SOD, GSH), were evaluated. The results showed that the 1-octacosanol formulation significantly reduced body weight and improved lipid profiles by decreasing levels of TC, TG, LDL and VLDL while increasing HDL levels. Additionally, the formulation exhibited notable antioxidant properties, contributing to its lipid-lowering effects. Statistical analysis using ANOVA and multiple comparison tests confirmed the significance of these findings, underscoring the therapeutic potential of 1-octacosanol in managing hyperlipidemia and mitigating associated cardiovascular risks. Conclusion: The test formulation of 1-octacosanol demonstrated a significant antihyperlipidemic effect in rats with high-fat diet-induced hyperlipidemia. The treatment effectively reduced serum levels of total cholesterol, triglycerides, LDL and VLDL while increasing HDL cholesterol levels. These marks suggest that 1-octacosanol has the potential as a therapeutic agent for managing hyperlipidemia, a key risk factor for cardiovascular diseases.

An Approach to Development and In-vivo Evaluation of Beta Sitosterol Phytosomes by Taguchi Orthogonal Array Design.

The research mainly focused on developing and optimizing beta-sitosterol phytosomes through a systematic Taguchi orthogonal array design and assessment of their performance in both beta-sitosterol phytosomes. The fabrication of phytosomes containing β-sitosterol was carried out using the rotary evaporation technique. An orthogonal array design was employed in the study to precisely optimize the phytosomes. In this two responses and three independent variables were analyzed. The data was analyzed by using statistical modeling. Characterization of these phytosomes involves Fourier transform infrared spectroscopy, entrapment efficiency, differential scanning calorimetry compatibility study, zeta potential and particle size. Based on the findings, an optimized phytsome formulation was developed to achieve the best results. The results indicated that beta-sitosterol phytosomes responses are significant. It effectively reduced body weight as well as levels of total cholesterol (126.120 ± 0.98 mg/dl), triglycerides (104.23 ± 2.8 mg/dl), HDL (39.31 ± 0.45 mg/dl), VLDL (21.67 ± 0.34 mg/dl), and LDL (76.43 ± 0.34 mg/dl) in rats compared to the other groups. The orthogonal array design study observed that the anti-hyperlipidemic activity of β-sitosterol was nearly as potent as that achieved with standard drug therapy.

Uric Acid Levels in Overweight and Obese Children, and Their Correlation With Metabolic Risk Factors.

Obesity is an ongoing medical condition that continues to rise on a global scale. Numerous metabolic disorders, such as type 2 diabetes mellitus, hyperlipidemia, and hyperuricemia, are closely associated with obesity. This particular study aims to investigate the occurrence of hyperuricemia and its association with other metabolic factors among children and adolescents aged 6 to 14 years who are overweight or obese residing in Riyadh, Saudi Arabia. In this research, a cross-sectional, descriptive, and analytical study was carried out on 339 children and adolescents. These participants were selected randomly from a list of patients who had sought medical care for overweight and obesity at the pediatric endocrinology, general pediatrics, and family medicine clinics in King Abdulaziz Medical City (KAMC), located in Riyadh, Saudi Arabia, in the period from January 2020 to January 2022. To gather the necessary data, the electronic medical records of the participating individuals were carefully reviewed, encompassing various relevant variables, including demographic characteristics, anthropometric measurements, serum uric acid levels, lipid profiles, and fasting blood sugar. Out of the total 339 participants, 48 (14.2%) were identified as overweight, while 291 (85.8%) were classified as obese. The study revealed that the overall prevalence of hyperuricemia among the participants was 54%. There was an increased risk of hyperuricemia associated with male gender and elevated levels of LDL and TG. The significant prevalence of hyperuricemia among children and adolescents who are overweight or obese is evident. In order to improve control and management of this condition, it is crucial to prioritize the promotion of a healthy lifestyle among these individuals.

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.

Correlation of APOE polymorphism, expression, and plasma levels with cardiac comorbidities among lipodystrophy in HIV-infected patients

Lipodystrophy in HIV-infected patients (LDHIV) includes morphological and metabolic abnormalities, including lipid and glucose metabolism. ApoE plays a role in the transport and clearance of lipoprotein. In the general population, ApoE 112 (rs429358) and 158 (rs7412) polymorphisms were linked to severe dyslipidemia. Therefore, we investigated ApoE polymorphism using PCR-RFLP in 200 HIV patients (100 with HIV-associated lipodystrophy (HIVLD), 100 without HIVLD), as well as 100 healthy controls. We also assessed ApoE expression using qRT-PCR and measured its level using ELISA. The APOE 4/4, 3/4, and 2/4 genotypes have been associated with a decreased risk of HIV-1 infection. (P = 0.0001, OR = 0.18; P = 0.006, OR = 0.87; P = 0.006, OR = 0.09) when compared between HIV-positive individuals and healthy controls. Conversely, APOE allele 2 was linked to a higher risk of acquiring HIV-1 (P = 0.03, OR = 3.02). APOE allele 2 was linked to a higher likelihood of HIVLD severity when compared between patients with and without HIVLD (P = 0.05, OR = 2.82). When comparing patients with HIVLD to healthy controls, the APOE 4/4 and 2/4 genotypes as well as allele 4 were linked with the reduced risk of LDHIV (P = 0.0006, OR = 0.21; P = 0.01, OR = 0.18; P = 0.0002, OR = 0.40). When compared to patients without HIVLD from healthy controls, the ApoE 4/4 genotype, 2 and 4 alleles, were linked to a reduced risk of developing HIVLD (P = 0.0009, OR = 0.14; P = 0.0001, OR = 0.17; P = 0.00001, OR = 0.39). When comparing impaired to normal cholesterol levels in patients without HIVLD, the ApoE 3/4 genotype was linked with the increased risk of impaired cholesterol levels (P = 0.02, OR = 3.37). When comparing impaired and normal glucose levels in patients without HIVLD, the ApoE 4/4 genotype was associated to an elevated risk of impaired glucose levels (P = 0.03, OR = 8.27). In multivariate analysis, independent impaired cholesterol, LDL, and glucose levels were associated with a higher risk of lipodystrophy severity (P = 0.04, OR = 2.33; P = 0.001, OR = 4.05; P = 0.05, OR = 2.63). ApoE expression was up-regulated in LDHIV with a fold change value of 4.02 compared to those without HIVLD. ApoE protein level was found to be higher in patients of the HIVLD group (3.01 mg/dL) compared to those without HIVLD group (2.83 mg/dL). In conclusion, individuals with ApoE allele 2 were at higher risk for HIV-1 acquisition and severity of HIVLD, whereas those with ApoE allele 4 were at reduced HIVLD severity and development risk. It’s possible that ApoE’s increased level and its overexpression are related to the ApoE allele 2 in HIVLD patients. The development of LDHIV may be facilitated by the APOE 3/4 and 4/4 genotypes as well as abnormal glucose and cholesterol levels.

Hepatoprotective Activity of Bixa orellana Plant Extract against Hepatotoxicity in Rodent

Introduction: Hepatotoxicity, or liver damage, can result from exposure to toxic substances such as medications, chemicals, alcohol, and environmental pollutants, affecting approximately 1.5 billion people worldwide. Although synthetic drugs offer therapeutic benefits, they often come with side effects. Medicinal plants may offer a viable alternative. This study examines Bixa Orellana, a plant known for its antioxidant properties, to evaluate its potential protective effects on the liver. Methods: The study used 45 Swiss Albino rats, divided into 9 groups. Hepatotoxicity was induced using carbon tetrachloride (CCl4). Group 1 was negative control group where only normal foods were given. Groups 2 to 6 were exposed to CCl4, while Groups 7 through 9 received low, medium, and high doses of Bixa Orellana extract, respectively. The treatments lasted for 42 days, after which the rats were sacrificed for analysis. Results: Liver function tests (SGPT and SGOT) showed significant improvements, particularly with medium (600mg/kg) and high (1200mg/kg) doses of the extract. Kidney function tests revealed promising results for creatinine levels with low (300mg/kg) and medium (600mg/kg) doses, although urea levels did not change significantly. The lipid profile analysis indicated substantial benefits at high (1200mg/kg) doses, with improvements in HDL, LDL, and cholesterol levels, though triglyceride levels did not show significant changes. Conclusion: The findings suggest that Bixa Orellana has considerable hepatoprotective effects. Further studies are needed to explore its potential as a therapeutic agent for liver protection and to develop detailed reports on its efficacy.

The Curative Hypolipidemic Effect, Antioxidant Activity, and Atherogenic Indexes of Methanolic Extract of Arbutus Pavarii Leaves

The aim of the study was to investigate the antioxidant activity and curative effect of (MEAPL) and its role in the treatment of hypercholesterolemia in male albino rats. The effect of (MEAPL) against hypercholesterolemia in rats was analyzed via examination of various types of parameters, (LDL), (HDL), (TC), and (TG), also liver enzymes (ALT, AST, G-GT, LDH, and ALP) besides proteins and MDA. Antioxidant enzymes (SOD, GR, GPx, and CAT), were measured in control and (HFD). We have found that the level of TC, LDL, TG, and liver enzymes were increased but the level of HDL decreased in HFD rats compared with control. Lipid peroxidation was determined by the level of MDA, which increased in HFD compared with control while antioxidant enzymes SOD, GR, GPx, and CAT were decreased. The results obtained revealed that MEAPL has a healing effect against hypercholesterolemia compared with the reference standard agent ˝Atorvastatin˝ and standard antioxidant vitamin C.

Metabolic and hormonal profiling in polycystic ovarian syndrome: insights into INSR gene variations.

Polycystic Ovary Syndrome (PCOS) is a hormonal disorder characterized by irregular periods, excess androgen levels, and polycystic ovaries, affecting many women of reproductive age. This study employed statistical and molecular analyses to compare hormone and metabolic markers between PCOS patients and controls. Sanger sequencing identified two INSR gene variants linked to high insulin and pre-diabetic conditions. Statistically, no significant age differences were detected (p = 0.492) between the overall PCOS patient pool and controls. However, a substantial variation in Vitamin D levels was observed within PCOS patients compared to controls (p = 0.0006), suggesting an association with PCOS. Correlations between Vitamin D and insulin, as well as HbA1c levels (R2 = 0.141 and 0.143, respectively), suggest Vitamin D's potential impact on glycemic control. Significant differences were found in HbA1c (p < 0.0001), insulin (p < 0.0001), and LDL (p = 0.0004) levels between PCOS patients and controls, highlighting marked disparities in these metabolic markers. LH levels also showed a significant contrast (p < 0.0001), while progesterone levels displayed a notable difference (p = 0.007) between the two groups. Correlation analyses within PCOS patients demonstrated associations among LDL, HbA1c, and insulin, with no such correlations observed in control cases. Additionally, Sanger sequencing identified two INSR gene variants, c.3614C > T (p.Pro1205Leu) and c.3355C > T (p.Arg1119Trp), associated with high insulin, LH, and pre-diabetic conditions. These amino acid changes may trigger metabolic imbalances and hormonal irregularities, potentially contributing to the development of PCOS. The findings highlight the multifaceted nature of PCOS, revealing significant metabolic, hormonal, and genetic differences compared to controls. These insights may inform tailored interventions and management strategies for the complex associations characteristic of PCOS.

Metformin and Caffeine’s Influence on Lipid Profile Indices of Streptozotocin-Induced Dyslipidemia in an Animal Model

Dyslipidemia has been linked to insulin resistance and hyperglycemia. Hyperglycemia, which is the outcome of either insufficient insulin production or insensitivity to insulin, is the hallmark of diabetes mellitus (DM). In this study, thirty-six (36) male Wistar rats with diabetes induced by streptozotocin were used to determine the effect of metformin and caffeine on blood glucose levels and lipid profile indices. The rats weighed between 150 and 200 grams and were split into six groups of six animals each at random. Group A was given unlimited access to chow (Grower feed) and water adlibitum. Group B was administered 60 mg/kg of streptozocin (STZ) without any medication, while Group C was given 60 mg/kg of STZ together with 50 mg/kg of metformin. Groups D and E were administered 60 mg/kg of streptozocin and 25 mg/kg and 50 mg/kg of caffeine, for a duration of 21 days respectively. Group F was given 50 mg/kg of caffeine together with 50 mg/kg of metformin for a duration of 21 days. After performing a post-hoc LSD comparison and using ANOVA to analyze the results, the lipid profile and blood glucose level were deemed significant at p&lt;0.05. A paired t-test was used to analyze body weight. Rats with diabetes had reduced body weight, whereas those receiving metformin and caffeine treatments had noticeably increased body weight. The findings demonstrated that whereas metformin and caffeine therapy greatly reduced blood glucose levels, STZ caused hyperglycemia in group B. However, diabetic rats had considerably higher levels of triglycerides (TG) and total cholesterol (TC), which were reduced by metformin and caffeine administration. HDL activity was considerably increased after treatment with metformin and caffeine, despite the rats' reduced HDL levels in group B. Rats with diabetes had considerably elevated levels of LDL and VLDL, and therapy with metformin and caffeine markedly restored their activity. The study shows that caffeine plus metformin may be utilized to control the lipid profile and blood glucose levels in diabetic rats.

Genetic support of causal association between lipid and glucose metabolism and stress urinary incontinence in women: a bidirectional Mendelian randomization and multivariable-adjusted study.

Stress urinary incontinence (SUI) is a common condition characterized by urethral sphincter failure and urine leakage. Its prevalence in women is higher than in men, and estimates of crude prevalence rates vary widely due to factors such as research methodologies, study populations, and underreporting by patients. This variability hinders research and impacts patient diagnosis, treatment, and quality of life. The complex etiology of SUI is not fully understood, and previous studies have primarily focused on non-invasive indicators. While emerging observational research suggests a correlation between SUI in women and abnormalities in lipid and blood metabolism, the underlying biological mechanisms and causal relationships require further investigation. This study aims to explore the causalities between SUI in women and lipid and blood metabolism. Using bidirectional univariate Mendelian randomization (MR), we investigated the causal association between SUI liability in women (case/control = 5,924/399,509) from UK Biobank and lipid and glucose metabolism, indicated by total cholesterol (TC, N = 61,166), low-density lipoproteins (LDL, N = 58,381), high-density lipoproteins (HDL, N = 60,812), triglycerides (TG, N = 60,027), fasting glucose (FG, N = 19,745), and fasting insulin (FI, N = 38,238) from ENGAGE consortium. To account for potential confounding effects, multivariable MR (MVMR) analyses were performed, adjusting for body mass index (BMI) and separately among lipid and glucose metabolism. We found that increased genetically proxied TC, LDL, and HDL levels were associated with an elevated risk of SUI in women (OR: 1.090-1.117, all P < 0.05), These associations were further supported by MVMR analyses with adjustment for BMI (OR: 1.087-1.114, all P < 0.05). Conversely, increased FG and FI were associated with reduced SUI reliability in women (OR: 0.731-0.815, all P < 0.05). When adjusting among lipid and glucose metabolism, only HDL and FI demonstrated causal effects. Reverse MR analyses provided no genetic evidence supporting the causal effect of SUI in women on lipid and blood metabolism (all P > 0.05). Our results reported that increased TC, LDL, and HDL are linked to higher SUI susceptibility in women, while higher FG and FI levels have a protective effect. In overweight/obese women with metabolic abnormalities, the positive associations between TC, LDL, and HDL levels and SUI indicate a higher risk.

Biological Evaluation of Bioactive Compounds of Selaginella plana in Treating Diabetic Neuropathy

Introduction: The study is aimed to assess the plant bioactive compounds of Selaginella plana in treating diabetic neuropathy. The plant components were assessed using ethanol as the solvent. Method: A phytochemical screening was conducted to ascertain the existence of secondary metabolites in the plant extracts. The efficacy of plant extract against neuropathic pain was determined using plantar test and Von Frey filament stimulation. Biochemical tests were performed to determine the level of SGOT, SGPT, ALP, HDL, CHO, LDL, Creatinine and Urea. The percentage yield of ethanol and aqueous extract was 19.22 g and 15.76 g, respectively. Result: The ethanolic extract showed presence of most of the phytoconstituents like alkaloids, flavonoids, carbohydrates, tannins, phytosterols, glycosides, proteins, and gum. Thus, ethanolic extract was used for further studies. In contrast to disease induced rats, rats given the extract chronically had a considerably shorter hind paw withdrawal latency. In STZ-induced diabetic rats, the mechanical withdrawal threshold dramatically reduced mechanical allodynia after 7 days by a dose of 400 mg/kg. Conclusion: The major findings of the study demonstrated that STZ-induced diabetic rats administered leaf extract had reduced neuropathic pain. It can be concluded that S. plana may be used as an alternative drug in the treatment of diabetic neuropathy.

The relationship between the new inflammatory markers and disease severity in patients with acute coronary syndrome

Background Inflammation plays a crucial role in the progression of acute coronary syndrome. Aims The aim of this study was to investigate the relationship between the SYNTAX score and new inflammatory markers including albumin-globulin ratio (AGR), C-reactive protein-to-albumin ratio (CAR), fibrinogen-to-albumin ratio (FAR), neutrophil-to-albumin ratio (NAR), and neutrophil percentage-to-albumin ratio (NPAR) in STEMI and NSTEMI patients. Methods The study involved 53 STEMI and 64 NSTEMI patients, and each patient group was evaluated separately. Multivariate linear regression analysis was utilised to identify independent risk factors associated with SYNTAX scores. Results Out of the 64 NSTEMI patients, 42 had low SYNTAX score (65.6%), and 22 had high SYNTAX score (34.4%). Patients with high SYNTAX scores had significantly higher levels of age, glucose, fibrinogen, monocyte, and FAR, and lower levels of albumin and total protein. We found that FAR and monocyte levels were independent predictors of the high SYNTAX score. The study also determined that the cut-off value for FAR as 9.99, with a sensitivity of 81% and a specificity of 73% for predicting high SYNTAX score in NSTEMI patients. Out of the 53 STEMI patients, 42 had low SYNTAX score (79.2%), and 11 had high SYNTAX score (20.8%). Patients with high SYNTAX scores exhibited significantly higher total cholesterol, LDL, and glucose levels, and lower albumin and total protein levels. Conclusions The FAR level is significantly linked with the high SYNTAX score and can be a useful marker for predicting the severity of disease in NSTEMI patients.

Lipid levels and multiple myeloma risk: insights from Meta-analysis and mendelian randomization

BackgroundLipid levels have been suggset to be correlated with multiple myeloma (MM) risk, though causality remains unconfirmed. To explore this further, a detailed study combining meta-analysis and Mendelian randomization (MR) was conducted.MethodsLiterature searches were performed on PubMed and Embase; summary data for plasma lipid traits were extracted from the IEU and MM data from the FinnGen database. Meta-analysis and MR were utilized to analyze the link of lipids with MM risk, including mediator MR to identify potential mediators. The study was conducted in accordance with PRISMA and STROBE-MR guidelines.ResultsObservational studies analyzed through meta-analysis showed that elevated levels of LDL, HDL, total cholesterol (TC), and triglycerides correlate with a lower risk of MM, with HRs of 0.73, 0.59, 0.60, and 0.84, respectively. MR analysis confirmed a potential causal link of triglyceride with a reduced MM risk (OR: 0.67, 95% CI: 0.46–0.98), independent of BMI. Mediation analysis pointed to X-11,423-O-sulfo-L-tyrosine and neuropilin-2 as potential mediators.ConclusionsThe findings suggest that higher lipid levels (LDL, HDL, TC, and triglycerides) are linked with a reduced MM risk, and higher triglyceride levels are causally associated with a reduced MM risk. This suggests new avenues for therapeutic interventions targeting MM.

Association between pseudoexfoliation syndrome and dyslipidemia: A case control study

: Pseudoexfoliation syndrome, also known as PEX 1, is a systemic micro fibrillopathy associated with ageing that is brought on by the gradual buildup of extracellular white and grey matter on various ocular and extra ocular structures. It is deposited in extra-ocular tissues such the heart, blood vessels, meninges, liver, and lungs. Numerous investigations have shown a connection between PEX and glaucoma. A person with PEX is typically thought to be at risk for acquiring glaucoma, and vice versa.Atherosclerosis is facilitated by dyslipidemia, which is an increase in plasma cholesterol, triglycerides (TGs), or both, or a low HDL level. A potential risk factor for the progression of cardiovascular disease is dyslipidemia. Numerous investigations have discovered abnormal lipid profiles in pseudoexfoliation syndrome patients, including elevated levels of triglycerides, cholesterol, and LDL. Due to the straight association between lipid levels, atherosclerosis, and cardiovascular risk, patients with PEX are shown to be at an elevated risk of cardiovascular and cerebrovascular events.To study the correlation between dyslipidemia and pseudoexfoliation syndrome in patients above 50 years of age and compare it with age matched controls.This case control study was conducted from November 2020 to November 2022 at SKIMS Medical College and Hospital, Srinagar and included 150 patients with PEX above 50 years of age and compared with age matched controls. In this study mean total cholesterol among cases was 176.88±34.76 mg/dl versus 172.94±51.51 mg/dl in controls. P-value for total cholesterol was statistically insignificant (0.438). Mean triglyceride level among cases was 180.11±54.70 mg/dl while as mean triglyceride level among controls was 163.14±46.21 mg/dl and P-value was found to be statistically significant. Mean LDL level among cases was 104.57±32.80 mg/dl while as in controls mean was 82.70±27.60 mg/dl. P-value for LDL levels was found to be statistically significant. Mean HDL levels among cases was found to be 41.93±8.94 mg/dl while as in controls mean was 39.67±13.73 mg/dl. P-value for HDL levels was statistically insignificant (0.09). Mean VLDL levels among cases was found to be 25.34±19.52 mg/dl while as in controls mean was 27.66±14.36mg/dl. P-value for VLDL levels was statistically insignificant (0.242).There is significant correlation between dyslipidemia and pseudoexfoliation syndrome in patients above 50 years of age.

Analysis of predictors of hemorrhagic transformation after reperfusion therapy with recombinant tissue plasminogen activator in patients with acute ischemic stroke: a single-center experience

BackgroundHemorrhagic transformation (HT) is a serious complication of thrombolytic therapy for acute ischemic stroke, limiting its indications and affecting treatment plans and clinical prognosis. Identifying risk factors for HT could help improve the risk–benefit ratio of thrombolytic therapy. We aimed to analyze the predictors of HT after reperfusion therapy with recombinant tissue plasminogen activator (rTPA) in patients with acute ischemic stroke. This study included 115 patients who received rTPA. All patients underwent history taking, clinical examination, neurological examination including Glasgow Coma Scale and National Institutes of Health Stroke Scale scores (NIHSS), radiological investigation, and cardiac investigation. Patients were followed up strictly every 2 h for 1st 24 h then for two weeks clinically using the NIHSS and radiologically using CT or MRI to detect HT.ResultsPatients with HT represented 21.7% of all patients receiving rTPA, while symptomatic intracranial hemorrhage (sICH) represented 6.9%. Patients with HT had significantly higher blood pressure, respiratory rate, atrial fibrillation rate, NIHSS score, INR, prothrombin time, neutrophil-to-lymphocyte ratio (NLR), and lower platelet count, LDL level, higher Fazekas score, lower ASPECT score, and prolonged onset-to-needle time.ConclusionPredicting HT in acute ischemic stroke patients is crucial for optimizing management and potentially improving outcomes. In our study, six predictors were associated with HT: higher respiratory rate, higher atrial fibrillation rate, higher NLR, lower LDL level, higher Fazekas score, lower ASPECT score, and onset-to-needle time greater than 180 min.

Phytochemical screening, molecular docking, antifertility investigations, and ADME potential of various extracts of Pandanus odoratissimus leaves.

The purpose of this study was to explore the molecular docking characteristics and antifertility impacts of petroleum ether extract (PEEPO) and chloroform (CHEPO) derived from Pandanus odoratissimus (PO) leaves. TriposSybyl-X 2.1 for molecular docking and Swiss ADME for ADME predictions were used. Antifertility activity was determined by using two invivo animal models, with a focus on estrogenic/antiestrogenic activity and anti-implantation effects. The findings showed that at different doses (100, 200, and 400 mg/kg), PEEPO had more anti-implantation effect than CHEPO. After taking either extract orally for up to 4,000 mg/kg, no acute toxicity was found. Furthermore, both extracts substantially raised blood oestrogen levels while lowering serum cholesterol and LDL levels, improving their antiimplantation and estrogenic activities, whether given alone or in combination with ethinyl estradiol. Molecular docking scores suggested strong interactions between phytochemicals in the extracts and estrogen receptors. ADME studies highlighted four phytochemicals present in PO leaves, showing high gastrointestinal absorption, blood-brain barrier permeability, and negative Log Kp values, indicating their potential as antifertility agents. The phytochemicals in both PEEPO and CHEPO demonstrated promising antifertility potential and interactions with estrogen receptors. Isolation of these phytochemicals could lead to the development of effective herbal antifertility formulations.

Predictive value of white matter hyperintensity burden combined with collateral circulation in mechanical thrombectomy for acute anterior circulation large vessel occlusion

ObjectiveTo investigate the correlation and predictive value of white matter hyperintensity (WMH) burden in conjunction with collateral circulation during mechanical thrombectomy (MT) for acute anterior circulation occlusion. MethodsA database comprising consecutive registrations of patients who underwent mechanical thrombectomy for acute anterior circulation large vessel occlusive cerebral infarction at Nanjing Drum Tower Hospital from January 2018 to December 2021 was analyzed. Collateral circulation was assessed using the American Society of Interventional and Therapeutic Neuroradiology/Society of Interventional Radiology (ASITN/SIR) scoring criteria. The good collateral group included ASITN/SIR grades 3 and 4, while the poor collateral group included grades 1 and 2. Additionally, white matter hyperintensity burden was evaluated using white matter hyperintensity volume and the Fazekas scoring system. A favorable functional outcome was defined as a modified Rankin scale (mRS) of 0–2 at 90 days. Multivariable logistic regression analyses and Spearman correlation analysis were employed to assess the correlation between white matter hyperintensity burden and unfavorable outcomes in mechanical thrombectomy. ResultsA total of 123 patients who underwent mechanical thrombectomy for acute anterior circulation occlusion were included (56.9 % male). Favorable outcomes were observed in 45.5 % (56/123) of cases. Those with a low ASITN/SIR scale (r = -1.33, 95 % CI: 0.26 (0.09–0.78), P=0.01; cutoff value = 2.5), low low-density lipoprotein cholesterol (LDL-C) level (r = -1.00, 95 % CI: 0.37 (0.15–0.92), P=0.03; cutoff value = 2.26), and high white matter hyperintense volume (r = 0.28, 95 % CI: 1.33 (1.03–1.71), P=0.03; cutoff value = 10.03) were more likely to experience unfavorable outcomes. Moreover, when compared to ASITN/SIR scale (AUC=89.6, 95 % CI: 0.09–0.78) and LDL level (AUC=62.8, 95 % CI: 0.15–0.92), white matter hyperintense volume demonstrated greater accuracy in predicting poor outcomes (AUC=94.4, 95 % CI: 1.03–1.71). Importantly, white matter hyperintense volume showed a positive correlation with the modified Rankin Scale (mRS) Score (r = 0.8289, P<0.0001). In brief, the burden of white matter hyperintensity is negatively correlated with collateral circulation in mechanical thrombectomy for acute anterior circulation occlusion. ConclusionsThe higher the burden of white matter hyperintensity, the worse the collateral circulation in mechanical thrombectomy for acute anterior circulation occlusion. The combination of high white matter hyperintensity volume and poor collateral circulation enhances might predict a worse clinical outcome of mechanical thrombectomy with acute anterior circulation occlusion.

Effect of a Phytochemical-Rich Olive-Derived Extract on Anthropometric, Hematological, and Metabolic Parameters.

Extra virgin olive oil is a fundamental component of the Mediterranean diet. It contains several molecules that sustain human well-being by modulating cellular metabolism and exerting antioxidant, anti-inflammatory, and anti-ageing effects to protect normal tissues, and it can exert anti-angiogenic and pro-apoptotic effects on cancer cells. Metabolites found in different parts of the olive tree, including leaves, also possess properties that might help in cancer prevention and promote wellness in aging. Olive mill wastewater (OMWW), a liquid residue produced during olive oil extraction, represents an environmental issue. However, it is rich in phytochemicals with potential beneficial properties. Dietary supplements based on OMWW can be produced for nutritional supplementation with advantages to the ecology. This work aims to measure hematochemical, anthropometric, and metabolomic parameters in volunteers taking an OMWW dietary supplement, Oliphenolia® (OMWW-OL). The supplementation of OMWW-OL 25 mL twice daily for 30 days was tested on a pilot cohort of volunteers with characteristics close to metabolic syndrome. Hematochemical, anthropometric, serum biomarkers and serum metabolomic parameters were analyzed before the intervention, at 30 days, and 30 days after stopping consumption. A total of 29 volunteers were enrolled, and 23 completed the study. The participants' parameters at baseline were measured, and then twice daily at 30 days of treatment and 30 days after assumption discontinuation. Although treatment was with an olive derivative, their weight did not increase. Their body mass index, instead of augmenting, slightly decreased, particularly in the women. Also, hydration increased, especially in the women, while blood pressure, glycemia, and insulin decreased. Cholesterol, high-density lipoproteins, and triglycerides were stable, and LDL levels decreased, while vitamin D levels, alongside calcium, perceptibly increased. Albumin also increased. All the values were in support of an equilibrium, with no damaging effects. By mass spectrometry analysis, we also found favorable changes in the vitamin D/histamine and homocysteine/methionine ratios, an increase in a new metabolite of unknown formula, and the vitamin D/unknown metabolite ratio. Supplementation of OMWW-OL has no detrimental effects and might imply the beneficial modulation of several biological parameters. Although this is a small pilot study, with limited potency, it preliminarily suggests that the OMWW extract use could be potentially valuable for people at risk of metabolic syndrome. Some of these parameters could also be relevant in supporting healthy ageing and in cancer prevention.

Evaluation of probiotic efficacy of indigenous yeast strain, Saccharomyces cerevisiae Y-89 isolated from a traditional fermented beverage of West Bengal, India having protective effect against DSS-induced colitis in experimental mice.

Increasing awareness regarding health promotion and disease prevention has driven inclusion of fermented foods and beverages in the daily diet. These are the enormous sources of beneficial microbes, probiotics. This study aims to isolate yeast strains having probiotic potential and effectivity against colitis. Initially, ninety-two yeast strains were isolated from Haria, an ethnic fermented beverage of West Bengal, India. Primary screening was done by their acid (pH 4) and bile salt (0.3%) tolerance ability. Four potent isolates were selected and found effective against Entamoeba histolytica, as this human pathogen is responsible to cause colitis. They were identified as Saccharomyces cerevisiae. They showed luxurious growth even at 37 oC, tolerance up to 5% of NaCl, resistance to gastric juice and high bile salt (2.0%) and oro-gastrointestinal transit tolerance. They exhibited good auto-aggregation and co-aggregation ability and strong hydrophobicity. Finally, heat map and principal component analysis revealed that strain Y-89 was the best candidate. It was further characterised and found to have significant protective effects against DSS-induced colitis in experimental mice model. It includes improvement in colon length, body weight and organ indices; reduction in disease activity index; reduction in cholesterol, LDL, SGPT, SGOT, urea and creatinine levels; improvement in HDL, ALP, total protein and albumin levels; decrease in coliform count and restoration of tissue damage. This study demonstrates that the S. cerevisiae strain Y-89 possesses remarkable probiotic traits and can be used as a potential bio-therapeutic candidate for the prevention of colitis.
