How to descript a clinical case correctly: For inquiry scientists and demanding doctors

The article presents step by step international CARE guidelines (CAse REport), which regulate the structure of the description of a clinical case and include a checklist of 13 points. This form of presentation of the material does not create any difficulties in understanding, does not require a long period of time to prepare a publication for the author, demonstrating a unique personalized experience and informing the medical community about interesting clinical manifestations, diagnostic or therapeutic approaches within a particular nosology, as well as describing rare or newly reported side effects of drugs or features of their prescription. Below as an example presented a clinical observation of a young man with diabetes mellitus of complex origin, which was diagnosed after the initial diagnosis of type 2 diabetes mellitus, which was later supplemented with recurrent pancreatitis, pancreatic cyst development and alcohol abuse with underlying severe hypertriglyceridemia (up to 67 mmol/l). Given the limited choice of glucose-lowering therapy, inability to prescribe metformin, glucagon-like peptide-1 agonists, infeasibility to use dipeptidyl peptidase 4 inhibitors and gliflozins (history of episodes of balanoposthitis), after a detailed discussion with the patient, a decision was made to prescribe a combination insulin drug – biphasic Lispro (RinLis Mix 25, Geropharm, Russia), which, together with fundamental lifestyle changes, strong alcohol avoidance, and regular medical follow-ups, allowed him to achieve glycemic targets and reduce plasma triglyceride levels, which once again supported the versatility of insulin as hypoglycemic agent, easiness to use and comprehensive glycemic control, if pre-mixed ultra-fast-acting insulin analogue and its protaminized analogue are prescribed. The prescription of insulin premix in this case is also justified in terms of clinical guidelines, as the man led a regular lifestyle, had low physical activity, an HbA1c level greater than 1.5% of the target value, as well as fasting and postprandial hyperglycemia.

Genetic inhibition of angiopoietin-like protein-3, lipids, and cardiometabolic risk.

RNA-based, antibody-based, and genome editing-based therapies are currently under investigation to determine if the inhibition of angiopoietin-like protein-3 (ANGPTL3) could reduce lipoprotein-lipid levels and atherosclerotic cardiovascular disease (ASCVD) risk. Mendelian randomisation (MR) was used to determine whether genetic variations influencing ANGPTL3 liver gene expression, blood levels, and protein structure could causally influence triglyceride and apolipoprotein B (apoB) levels as well as coronary artery disease (CAD), ischaemic stroke (IS), and other cardiometabolic diseases. RNA sequencing of 246 explanted liver samples and genome-wide genotyping was performed to identify single-nucleotide polymorphisms (SNPs) associated with liver expression of ANGPTL3. Genome-wide summary statistics of plasma protein levels of ANGPTL3 from the deCODE study (n = 35 359) were used. A total of 647 carriers of ANGPTL3 protein-truncating variants (PTVs) associated with lower plasma triglyceride levels were identified in the UK Biobank. Two-sample MR using SNPs that influence ANGPTL3 liver expression or ANGPTL3 plasma protein levels as exposure and cardiometabolic diseases as outcomes was performed (CAD, IS, heart failure, non-alcoholic fatty liver disease, acute pancreatitis, and type 2 diabetes). The impact of rare PTVs influencing plasma triglyceride levels on apoB levels and CAD was also investigated in the UK Biobank. In two-sample MR studies, common genetic variants influencing ANGPTL3 hepatic or blood expression levels of ANGPTL3 had a very strong effect on plasma triglyceride levels, a more modest effect on low-density lipoprotein cholesterol, a weaker effect on apoB levels, and no effect on CAD or other cardiometabolic diseases. In the UK Biobank, the carriers of rare ANGPTL3 PTVs providing lifelong reductions in median plasma triglyceride levels [-0.37 (interquartile range 0.41) mmol/L] had slightly lower apoB levels (-0.06 ± 0.32 g/L) and similar CAD event rates compared with non-carriers (10.2% vs. 10.9% in carriers vs. non-carriers, P = .60). PTVs influencing ANGPTL3 protein structure as well as common genetic variants influencing ANGPTL3 hepatic expression and/or blood protein levels exhibit a strong effect on circulating plasma triglyceride levels, a weak effect on circulating apoB levels, and no effect on ASCVD. Near-complete inhibition of ANGPTL3 function in patients with very elevated apoB levels may be required to reduce ASCVD risk.

Alterations in Th17 Cells and Non-Classical Monocytes as a Signature of Subclinical Coronary Artery Atherosclerosis during ART-Treated HIV-1 Infection.

Cardiovascular disease (CVD) remains an important comorbidity in people living with HIV-1 (PLWH) receiving antiretroviral therapy (ART). Our previous studies performed in the Canadian HIV/Aging Cohort Study (CHACS) (>40 years-old; Framingham Risk Score (FRS) > 5%) revealed a 2-3-fold increase in non-calcified coronary artery atherosclerosis (CAA) plaque burden, measured by computed tomography angiography scan (CTAScan) as the total (TPV) and low attenuated plaque volume (LAPV), in ART-treated PLWH (HIV+) versus uninfected controls (HIV-). In an effort to identify novel correlates of subclinical CAA, markers of intestinal damage (sCD14, LBP, FABP2); cell trafficking/inflammation (CCL20, CX3CL1, MIF, CCL25); subsets of Th17-polarized and regulatory (Tregs) CD4+ T-cells, classical/intermediate/non-classical monocytes, and myeloid/plasmacytoid dendritic cells were studied in relationship with HIV and TPV/LAPV status. The TPV detection/values coincided with higher plasma sCD14, FABP2, CCL20, MIF, CX3CL1, and triglyceride levels; lower Th17/Treg ratios; and classical monocyte expansion. Among HIV+, TPV+ versus TPV- exhibited lower Th17 frequencies, reduced Th17/Treg ratios, higher frequencies of non-classical CCR9lowHLADRhigh monocytes, and increased plasma fibrinogen levels. Finally, Th17/Treg ratios and non-classical CCR9lowHLADRhigh monocyte frequencies remained associated with TPV/LAPV after adjusting for FRS and HIV/ART duration in a logistic regression model. These findings point to Th17 paucity and non-classical monocyte abundance as novel immunological correlates of subclinical CAA that may fuel the CVD risk in ART-treated PLWH.

Unlocking the mysteries of VLDL: exploring its production, intracellular trafficking, and metabolism as therapeutic targets

Reducing circulating lipid levels is the centerpiece of strategies for preventing and treating atherosclerotic cardiovascular disease (ASCVD). Despite many available lipid-lowering medications, a substantial residual cardiovascular risk remains. Current clinical guidelines focus on plasma levels of low-density lipoprotein (LDL). Recent attention has been given to very low-density lipoprotein (VLDL), the precursor to LDL, and its role in the development of coronary atherosclerosis. Preclinical investigations have revealed that interventions targeting VLDL production or promoting VLDL metabolism, independent of the LDL receptor, can potentially decrease cholesterol levels and provide therapeutic benefits. Currently, methods, such as mipomersen, lomitapide, and ANGPTL3 inhibitors, are used to reduce plasma cholesterol and triglyceride levels by regulating the lipidation, secretion, and metabolism of VLDL. Targeting VLDL represents an avenue for new lipid-lowering strategies. Interventions aimed at reducing VLDL production or enhancing VLDL metabolism, independent of the LDL receptor, hold promise for lowering cholesterol levels and providing therapeutic benefits beyond LDL in the management of ASCVD.

A novel fully human anti-NT-ANGPTL3 antibody from phage display library exhibits potent ApoB, TG, and LDL-C lowering activities in hyperlipidemia mice.

Dyslipidemia is characterized by elevated plasma levels of low-density lipoprotein cholesterol (LDL-C), triglycerides (TG), and TG-rich lipoprotein (TGRLs) in circulation, and is closely associated with the incidence and development of cardiovascular disease. Angiopoietin-like protein 3 (ANGPTL3) deficiency has been identified as a cause of familial combined hypolipidemia in humans, which allows it to be an important therapeutic target for reducing plasma lipids. Here, we report the discovery and characterization of a novel fully human antibody F1519-D95aA against N-terminal ANGPTL3 (NT-ANGPTL3), which potently inhibits NT-ANGPTL3 with a KD as low as 9.21 nM. In hyperlipidemic mice, F1519-D95aA shows higher apolipoprotein B (ApoB) and TG-lowering, and similar LDL-C reducing activity as compared to positive control Evinacumab (56.50% vs 26.01% decrease in serum ApoB levels, 30.84% vs 25.28% decrease in serum TG levels, 23.32% vs 22.52% decrease in serum LDLC levels, relative to vehicle group). Molecular docking and binding energy calculations reveal that the F1519-D95aA-ANGPTL3 complex (10 hydrogen bonds, -65.51 kcal/mol) is more stable than the Evinacumab-ANGPTL3 complex (4 hydrogen bonds, -63.76 kcal/mol). Importantly, F1519-D95aA binds to ANGPTL3 with different residues in ANGPTL3 from Evinacumab, suggesting that F1519-D95aA may be useful for the treatment of patients resistant to Evinacumab. In conclusion, F1519-D95aA is a novel fully human anti-NT-ANGPTL3 antibody with potent plasma ApoB, TG, and LDL-C lowering activities, which can potentially serve as a therapeutic agent for hyperlipidemia and relevant cardiovascular diseases.

The protective role of virgin olive oil and vitamin E on mercury-induced hepatic, renal, testicular and adrenal toxicity in the rabbit (Oryctolagus cuniculus)

This study aimed to strengthen the antioxidant defenses against the toxic effect of mercury, by administering a synthetic antioxidant (vitamin E) and a natural product rich in antioxidant compounds (virgin olive oil) to rabbits. Hepatic and renal biomarker levels, cortisol and testosterone synthesis, mercury concentration, relative weight of organs, and tissue architecture were studied. The results showed a significant decrease in the plasma alkaline phosphatase (ALP), plasma aspartate aminotransferase (AST), serum alanine aminotransferase (ALT), plasma testosterone levels, and relative weight of the liver, testes, and adrenal in the mercury treated group (group M), while the other indices were significantly increased in the m-group compared to the control (group C). However, the group treated with olive oil combined with mercury (group O) showed a significant decrease in the ALP, AST, ALT, testosterone levels, and adrenal relative weight, while plasma creatinine, uric acid levels, mercury concentration in organs, and the kidney relative weight were significantly increased. Vitamin E supplementation (group E) led to a significant decrease in the ALP, testosterone levels, and adrenal relative weight, a significant increase was observed in plasma levels of triglycerides, creatinine, and uric acid. Histological sections of the liver, kidney, testis, and adrenal of group M showed severe tissue damage, while the other groups showed less important tissue alterations demonstrating that supplementation with natural or synthetic antioxidants can protect against the toxicity of heavy metals such as mercury, improving the health of rabbits.

Plasma cholesterol and triglyceride levels in black-necked pheasants, gray and chukar partridges with cannibalism treated with silymarin and tryptophan

Plasma cholesterol and triglyceride levels were studied in black-necked pheasants, gray partridges and chukar partridges divided into 4 groups (n=12 in each group; n=6 by sex): first group (negative control) – clinically healthy birds, second group – birds treated with tryptophan, third group – birds treated with sylimarin, fourth group (positive control) – birds with signs of cannibalism. In the pheasants and chukars with signs of cannibalism, cholesterol levels were higher than these in the control group. On the opposite, the triglyceride levels in the other three groups of birds with canniba­lism were substantially lower than those in the healthy group. Supplementation with tryptophan tended to increase blood cholesterol and triglycerides in pheasants, gray and chukar partridges. In the groups treated with silymarin, the levels of the studied indicators were significantly higher in comparison to birds with cannibalism.

Pancreatitis as a Main Consequence of APOC2-Related Hypertriglyceridemia: The Role of Nonsense and Frameshift Variants.

APOC2-related hypertriglyceridemia occurs due to biallelic variants of this gene. Here, genotype-phenotype architecture of all pathogenic APOC2 variants is investigated among heterozygous and homozygous individuals. Clinical heterogeneity of various types of the variants is also described, and pancreatitis in more than half of homozygotes carrying chain-termination variants is highlighted as well. For this study, patients were selected who had a plasma triglyceride level above 250 mg/dL. The coding and intronic regions of the APOC2 gene were amplified using the Sanger sequencing to investigate the presence of variants. The genotypes, lipid profiles, and detailed clinical features were documented for all APOC2-related patients and heterozygous individuals. Pathogenicity of the variants was predicted and categorized using available bioinformatics tools such as MutationTaster and PolyPhen-2 and ACMG criteria. MetaDome and Phyre2 were applied for structural and functional in silico analyses. 40% (12 out of 30) of APOC2 variants were chain-termination (nonsense and frameshift) variants. These types of variants were determined in 60.53% of patients. 55% of these patients showed pancreatitis followed by lipemia retinalis (29%), abdominal pain (24%), hepatosplenomegaly (24%), and xanthomas (18%). The mean age of onset was about 22 years old. In at least 50% of 38 homozygous individuals, the TG level was more than 2000 mg/dL. More than 25% of heterozygous individuals showed at least one symptom. Pancreatitis and a severe form of HTG were found in 5 and 2% of heterozygous individuals, respectively. The main clinical features of APOC2-related hypertriglyceridemia include pancreatitis, lipemia retinalis, abdominal pain, hepatosplenomegaly, and xanthomas. Nonsense and frameshift homozygous variants usually lead to a severe form of hypertriglyceridemia. Pancreatitis is one of the main consequences of these types of mutations; thus, it is important to consider this point when evaluating asymptomatic individuals. Heterozygous individuals may become symptomatic due to the role of unknown modifying agent including environmental genetic factors.

Simultaneous quantitative LC-MS/MS analysis of 13 apolipoproteins and lipoprotein (a) in human plasma.

Numerous studies have revealed a close correlation between the levels of apolipoproteins (Apos) (including lipoprotein(a) [Lp(a)]) and an increased risk of cardiovascular disease in recent decades. However, clinically, lipid profiling remains limited to the conventional plasma levels of cholesterol, triglyceride, ApoA1, and ApoB, which brings the necessity to quantify more apolipoproteins in human plasma. In this study, we simultaneously quantified 13 apolipoproteins and Lp(a) in 5 μL of human plasma using the LC-MS/MS platform. A method was developed for the precise detection of Lp(a), ApoA1, A2, A5, B, C1, C2, C3, D, E, H, L1, M, and J. Suitable peptides were selected and optimized to achieve clear separation of each peak. Method validation consisting of linearity, sensitivity, accuracy and precision, recovery, and matrix effects was evaluated. The intra-day CV ranged from 0.58% to 14.2% and the inter-day CV ranged from 0.51% to 13.3%. The recovery rates ranged from 89.8% to 113.7%, while matrix effects ranged from 85.4% to 113.9% for all apolipoproteins and Lp(a). Stability tests demonstrated that these apolipoproteins remained stable for 3 days at 4 °C and 7 days at -20 °C. This validated method was successfully applied to human plasma samples obtained from 45 volunteers. The quantitative results of ApoA1, ApoB, and Lp(a) exhibited a close correlation with the results from the immunity transmission turbidity assay. Collectively, we developed a robust assay that can be used for high-throughput quantification of apolipoproteins and Lp(a) simultaneously for investigating related risk factors in patients with dyslipidemia.

Evaluation of the anti-obesity effect of Sambucus nigra L. (elderberry) and Vitex agnus-castus L. (chasteberry) extracts in high-fat diet-induced obese rats.

The aim of this study was to investigate the effects of S. nigra L. and V. agnus-castus L. plants on obesity in vivo. Extracts were prepared from S. nigra leaves, flowers, fruits and from V. agnus-castus leaves, flowers, and fruits using 100% water and 70% ethanol. The total phenol and flavonoid contents of the extracts were quantified spectrophotometrically. The findings revealed that the ethanol extracts of V. agnus-castus and S. nigra flowers had the highest phenolic content, while the ethanol extracts of S. nigra flowers and V. agnus-castus leaves had the highest flavonoid content. Qualification and quantification of the phenolic contents of the extracts were carried out using liquid chromatography-high resolution mass spectrometry (LC-HRMS) analyses. The study investigated the effects of various extracts on plasma levels of leptin, insulin, triiodothyronine (T3), thyroxine (T4), triglycerides, high-density lipoprotein (HDL), low-density lipoprotein (LDL) and lipase enzyme in obesity-induced rats. The results showed that the ethanol extract of V. agnus-castus flowers, as well as the ethanol and water extracts of V. agnus-castus leaves, resulted in body weight reduction in rats with obesity. Additionally, these extracts were found to decrease serum levels of LDL, triglycerides, leptin, lipase, TNF-α, and IL-1β while increasing levels of HDL and adiponectin. The LC-HRMS results demonstrated that all three extracts exhibited relatively high concentrations of luteolin-7-glycoside and kaempferol, in comparison to the other extracts. The ethanol extract of V. agnus-castus flowers contained 653.04mg/100g of luteolin-7-glycoside and 62.63mg/100g of kaempferol. The ethanol extract of V. agnus-castus leaves contained 1,720.26mg/100g of luteolin-7-glycoside and 95.85mg/100g of kaempferol. The water extract of V. agnus-castus leaves contained 690.49mg/100g of luteolin-7-glycoside and 194.41mg/100g of kaempferol. The study suggests that the ethanol extract of V. agnus-castus flowers and leaves, as well as the water extract of V. agnus-castus leaves, may have potential benefits in treating obesity. However, further controlled clinical studies are necessary to evaluate the clinical efficacy of V. agnus-castus in treating obesity and investigate the in vivo anti-obesogenic effects of luteolin-7-glycoside and kaempferol separately, both in their pure form and in combination.

A comparative study of the hypolipidemic effects and mechanisms of action of Laminaria japonica- and Ascophyllum nodosum-derived fucoidans in apolipoprotein E-deficient mice.

The structural characteristics of fucoidans exhibit species and regional diversity. Previous studies have demonstrated that Laminaria japonica- and Ascophyllum nodosum-derived fucoidans have type I and type II fucosyl chains, respectively. These chemical differences may contribute to distinct hypolipidemic effects and mechanisms of action. Chemical analysis demonstrated that the percentage contents of sulfate, glucuronic acid, and galactose were higher in L. japonica-derived fucoidans than those of A. nodosum-derived fucoidans. In hyperlipidemic apolipoprotein E-deficient mice, both A. nodosum- and L. japonica-derived fucoidans significantly decreased the plasma and hepatic levels of total cholesterol and triglyceride, leading to the reduction of atherosclerotic plaques. Western blotting experiments demonstrated that these fucoidans significantly enhanced the expression and levels of scavenger receptor B type 1, cholesterol 7 alpha-hydroxylase A1, and peroxisome proliferator-activated receptor (PPAR)-α, contributing to circulating lipoprotein clearance and fatty acid degradation, respectively. Differentially, L. japonica-derived fucoidan significantly increased the LXR/ATP-binding cassette G8 signaling pathway in the small intestine, as revealed by real-time quantitative PCR, which may lead to further cholesterol and other lipid excretion. Collectively, these data are useful for understanding the hypolipidemic mechanisms of action of seaweed-derived fucoidans, and their potential application for the prevention and/or treatment of atherosclerotic cardiovascular diseases.

Study on the Influence of Changes in Glucolipid Metabolism Parameters on the Incidence of Postoperative Complications in Patients Undergoing Renal Transplantation.

Changes in glucolipid metabolism parameters in patients undergoing renal transplantation (RT) and their influences on the incidence of postoperative complications were analysed. The objective was to provide a reference for clinical practice and reliable and safe implementation of RT. A total of 131 patients treated with RT at our institution from January 2019 to March 2024 were selected for retrospective analysis: 71 patients who developed postoperative complications (research group) and 60 patients who did not (control group). Differences in fasting plasma glucose (FPG), glycosylated haemoglobin (HbA1c), total cholesterol (TC) and triglyceride (TG) levels before and three days after surgery were compared, and their predictive value for postoperative complications was analysed. In addition, relevant factors influencing complications after RT were identified. HbA1c level changed significantly in neither group after surgery (p > 0.05), but FPG, TG and TC levels increased in both groups (p < 0.05). Differences in FPG and TC levels before and after surgery were larger than those in the control group (p < 0.05). The receiver operating characteristic curve revealed the excellent diagnostic value of differences in FPG and TC levels for postoperative complications, and logistic regression analysis indicated that such differences were independent risk factors for complications after RT (p < 0.05). The early evaluation of postoperative complications can be achieved by monitoring differences in FPG and TC levels before and after RT, allowing for the timely formulation and implementation of interventions.

INFLUENCE OF FERMENTED MELON SEED (OGIRI) PROTEIN ISOLATE ON POSTPRANDIAL BLOOD GLUCOSE LEVELS IN DIABETIC RATS

ABSTRACT Abstract Introduction Diabetes mellitus is a prevalent endocrine disorder affecting millions worldwide, characterized by chronic hyperglycemia and associated with serious complications. Aim This study aimed to evaluate the anti-diabetic properties of Ogiri Protein Isolate (OPI) derived from fermented melon seeds (Citrullus vulgaris) and its effects on blood glucose levels, lipid profiles, and key organs in alloxan-induced diabetic rats. Methods Forty-two rats were divided into seven groups: positive control, negative control, diabetic group treated with 20% OPI, non-diabetic group treated with 20% OPI, diabetic group treated with 10% OPI, non-diabetic group treated with 10% OPI, and diabetic group treated with 80mg/kg Glibenclamide for 14 days. Fasting serum glucose levels, feed and water intake, weight gain, and plasma HDL-cholesterol and triglyceride levels were measured. Results OPI treatment significantly reduced fasting serum glucose levels in diabetic rats. There was a significant (p&lt;0.05) decrease in feed and water intake in treated groups. Weight gain improved in OPI-treated diabetic rats compared to untreated diabetic rats. Plasma HDL-cholesterol levels increased significantly in all treated groups compared to the control, with the highest levels in non-diabetic and untreated groups. Similar trends were observed in plasma and liver triglycerides. Conclusion The findings suggest that OPI possesses anti-diabetic properties, significantly lowering blood glucose levels and improving lipid profiles in diabetic rats. OPI holds promise as a potential therapeutic agent for diabetes management. Further research is needed to validate these results in human studies. Keywords: Ogiri Protein Isolate (OPI), anti-diabetic, Diabetes mellitus, Postprandial blood glucose and Alloxan.

Lifestyle and mood correlates of cardiometabolic risk in people with serious mental illness on second-generation antipsychotic medications.

Cardiovascular morbidity and mortality are high in people with serious mental illness (SMI). This problem is mediated, at least in part, by metabolic side effects of second-generation antipsychotics (SGAs) and by unhealthy lifestyle behaviors. We asked whether oral glucose tolerance testing (oGTT) or hemoglobin A1c (HbA1c) is superior in identifying people with SMI at high cardiometabolic risk and whether this risk is shaped by mood, cognition, or lifestyle habits. We evaluated 40 patients with schizophrenia, schizoaffective, or bipolar disorder receiving SGAs by oGTT, HbA1c, comprehensive metabolic and lipid panels, and CRP. Mood was assessed using the Patient Health Questionnaire (PHQ-9), and cognition was assessed using the Saint Louis University Mental Status examination. Diet was assessed using the UK Diabetes and Diet Questionnaire (UKDDQ), and physical activity was assessed using daily step counts. Most patients had prediabetes (preDM) or diabetes mellitus (DM), 72.5% by oGTT, and 52.5% by HbA1c criteria. Pulse rates and insulin resistance indices (Homeostatic Model Assessment of Insulin Resistance, HOMA IR; Matsuda) were significantly different between patients classified as normal or with preDM/DM, using either oGTT or HbA1c criteria. Patients with preDM/DM by HbA1c but not oGTT criteria also had higher waist/hip ratios, triglyceride, and CRP levels (p<0.05). A strong negative correlation was found between average daily step counts and CRP levels (rho = -0.62, p<0.001). Higher UKDDQ scores, or unhealthier diet habits, were associated with higher fasting plasma glucose (rho = 0.28, p = 0.08), triglyceride levels (rho = 0.31, p = 0.05), and insulin resistance (HOMA IR: rho = 0.31, p = 0.06). Higher PHQ-9 scores correlated with lower 2h-oGTT glucose levels (rho = -0.37, p<0.05). OGTT screening is superior to HbA1c screening in detecting preDM and DM early. Patients identified with preDM/DM by oGTT or HbA1c screening are insulin-resistant and have higher pulse rates. Abdominal obesity, unfavorable lipid profiles, and higher CRP levels were noted in patients screened by HbA1c, but not by oGTT. Low physical activity, low depression scores, and unhealthy diet habits were associated with higher CRP and higher glucose and triglyceride levels, respectively. Future studies should assess the impact of specifically tailored individual lifestyle counseling and medical management interventions in this high-risk population.

Relationships of apolipoprotein E genotypes with a cluster of seven in persons with type 2 diabetes.

The objective of the study was to determine if there would be statistically significant differences or trends among apolipoprotein E genotypes (2/2, 2/3, 2/4, 3/3, 3/4, and 4/4) for each member of the cluster of seven associated with type 2 diabetes (T2D). The cluster of seven includes abdominal obesity, hypertension, platelet hyperaggregability, hyperglycemia, dyslipidemia (decreased plasma levels of high-density lipoprotein cholesterol (HDL-C) and increased plasma levels of triglycerides)), increased low-density lipoprotein (LDL) oxidation, and increased inflammation. Forty-six patients with well-controlled T2D participated in the study. Abdominal obesity (assessed by waist circumference), hypertension (measured by manual sphygmomanometry), platelet hyperaggregability (measured by bleeding time), hyperglycemia (by enzymatic kit and spectrophotometry), decreased plasma levels of HDL-C and increased plasma levels of triglycerides (by enzymatic kit and spectrophotometry), increased LDL oxidation (measured by LDL conjugated dienes using spectrophotometry) and increased inflammation measured by C-reactive protein (CRP) (by EIA kit) were determined. All genotypes, except 2/2 were found in the population studied. Abdominal obesity did not vary significantly across the five genotypes. However, glucose levels trended progressively higher going from 2/3 to 2/4 to 3/4 to 4/4. Systolic blood pressure was higher in 3/4 compared to 2/4 and trended higher in 3/4 compared to 3/3. Diastolic blood pressure trended higher in 3/3 vs 2/4 and significantly higher in 3/4 compared to 2/4. Triglycerides trended higher in 3/4 vs 3/3 while HDL-C came close to trending downward in 4/4 compared to 2/4. Bleeding time was unaffected by genotype. Plasma LDL conjugated dienes trended higher in 3/4 vs 2/4 and were significantly higher in 3/4 vs 3/3. CRP trended higher in 4/4 vs 2/3. We can conclude that those with at least one 4 allele in the presence of another allele being 2, 3 or 4 is potentially (in the case of trends) deleterious or is deleterious in terms of hyperglycemia, hypertension (systolic and diastolic blood pressure), dyslipidemia, LDL conjugated dienes and CRP levels.

Various apolipoprotein E genotypes relate to responsiveness to flaxseed lignan complex in older persons with type 2 diabetes mellitus.

Objective. The objective of the study was to determine if there would be statistically significant differences or trends among apolipoprotein E genotypes in the responsiveness of members of a cluster of seven measures in older persons with type 2 diabetes mellitus (T2DM) consuming flaxseed lignan complex (FLC). The cluster of seven are abdominal obesity, hypertension, platelet hyperaggregability, hyperglycemia, dyslipidemia (decreased plasma levels of high-density lipoprotein cholesterol (HDLc), and increased plasma levels of triglycerides), increased low-density lipoprotein (LDL) oxidation and increased inflammation. All cluster members exacerbate T2DM. Methods. Sixteen patients with well-controlled T2DM participated in this double-blind randomized, placebo-controlled crossover study consisting of four visits. Apolipoprotein E genotyping was done at visit one. The cluster of seven, diet, exercise, smoking and medication use were assessed at each visit. Results. The 3/4 genotype showed a stronger downward trend in systolic blood pressure compared to the 3/3 genotype with no trend or significant difference in the 2/4 genotype. There was a downward trend in diastolic blood pressure in genotype 3/3 compared genotype 2/4, which showed no significant difference or trend. Only genotype 3/4 showed a significant drop in diastolic pressure compared to genotypes 2/4 and 3/3. HDLc only showed a downward trend in 3/4 relative to genotypes 2/4 and 3/3. LDL apolipoprotein B oxidation (LDL-Box) only showed an upward trend in 3/3 compared to genotypes 2/4 and 3/4. There were no other significant differences or trends by genotype in the cluster of seven. Conclusions. It appears that those with the 2/4 genotype may not benefit from FLC, those with 3/3 and 3/4 genotypes may benefit only in terms of systolic and diastolic pressures, those with the apo E 3/4 genotype should perhaps avoid FLC to manage HDLc, and those with the 3/3 genotype should perhaps avoid FLC to manage LDL apolipoprotein B oxidation.

Effects of the replacement corn meal by whole mango meal on tambaqui (Colossoma macropomum) diet: Digestibility, growth performance, biochemical, and hematological responses.

This study evaluated the digestibility of whole mango (Mangifera indica) meal (WMM) and determined the growth performance, intestinal enzyme activity, and metabolic and hematologic responses of tambaqui (Colossoma macropomum) juveniles fed diets containing different proportions of corn meal (CM) substitution by WMM. Fish fed with graded levels of WMM (0 (control), 80, 160, 240, and 320 g kg diet-1), replacing part of the dietary CM. The apparent digestibility coefficients of WMM were above 96%. Diets with WMM did not affect growth performance or intestinal enzyme activity. However, they showed a positive linear effect on plasma glucose, amino acids, and albumin levels and a negative linear effect on hepatic aspartate aminotransferase activity and hepatic glycogen, plasma cholesterol, and hemoglobin levels. Increased erythrocyte values and decreased plasma triglyceride levels were verified in fish fed 80 and 160 g WMM kg diet-1. In conclusion, the WMM may be a viable alternative to the tambaqui juveniles' diet, and WMM could replace up to 16% of CM without harming the growth and health of tambaqui juveniles.

Influence of vagus nerve and spleen ablation on brown adipose tissue histology of hypothalamic obese and non-obese male Wistar rats

Vagus nerve and spleen can influence metabolic function and adiposity. Brown adipose tissue is an organ specialized in thermogenesis, a biochemistry process of lipids degradation that results in heat production, elevating energy expenditure and contributing to anti-obesity effects. Aim: Here, we evaluated the impact of vagus nerve and spleen absence on histology and lipid deposition of brown adipose tissue from non-obese and hypothalamic obese male Wistar rats. Methods: Hypothalamic obesity was induced by neonatal glutamate L-monosodium (4g/Kg) administration during the first post-natal days. Control rats received equimolar saline. At 60 days of life, obese and control groups underwent surgery: vagotomy, splenectomy, and sham. At 150 days of life, the animals were weighed and measured. Blood was collected for biochemistry analysis of glucose and triglycerides, and insulin resistance evaluated. Moreover, white adipose tissue and brown adipose tissue depots were removed and weighed. Brown adipose tissue was histologically analyzed. Results: In obese animals, elevated adiposity, hypertriglyceridemia, insulin resistance and higher lipid deposition in brown adipose tissue were noted. Vagus nerve ablation displayed more pronounced anti-adiposity effects, improving triglyceride plasma levels and insulin resistance in the obese rats compared to the control group. Moreover, spleen absence, especially in the obese group, raises nuclei number and reduced adipocyte size. These responses were amplified by vagus nerve ablation. Conclusion: Hypothalamic obese rats show excessive adiposity and metabolic dysfunctions related to brown adipose tissue hypofunction. Vagus nerve and spleen absence reduced lipid deposition on brown adipose tissue of obese rats, suggesting reactivation of thermogenesis.

Evaluation of the Suitability of Using Anticholesterol Drugs in Cholesterol Patients at Sekip Public Health Centre Palembang

Dyslipidemia is a condition that increases plasma cholesterol, LDL, and triglyceride levels, decreases HDL levels, or causes a combination of abnormalities. In amounts sufficient for what the body needs, cholesterol works to produce hormones, vitamin D, and other components. Cholesterol is produced by the liver and can also be found in animal products. This study aims to determine the profile of treatment and the suitability of the use of anticholesterol drugs in patients with high cholesterol at Sekip Public Health Centre Palembang. This research is non-experimental, using quantitative methods and 40 samples. The demographic results of the total cholesterol levels of patients who experienced a decrease were 100 patients (100%). Demographics of patients by gender: mostly female, as many as 30 patients (75%). Demographics of patients by age: mostly in the age category 56–65 years, as many as 16 patients (40%). Demographics of patients based on comorbidities: the most common was diabetes mellitus, with as many as 12 patients (30%) The highest use of anticholesterol drugs is in the statin group, namely simvastatin (100%). The suitability of the selection of anticholesterol drugs was 100% for 100 patients. The suitability of the selection of the anticholesterol dose in 100 patients (100%)

Genistein in combination with Chlorogenic acid ameliorates insulin resistance and oxidative stress in skeletal muscle of high-fat diet fed mice

Objectives: Increasing evidence has demonstrated that oxidative stress plays a significant role in the pathogenesis of muscle insulin resistance. The beneficial impacts of genistein (GEN) and chlorogenic acid (CGA) on insulin resistance have already been revealed. However, their combined effects on skeletal muscle oxidative stress and insulin resistance have not been completely understood. The aim of the present study was to determine the effect of GEN in combination with CGA on skeletal muscle insulin resistance in high-fat diet (HFD) fed C57BL/6 mice.&#x0D; Methods: C57BL/6 male mice were fed an HFD for 15 weeks. The mice were then divided into five groups: standard chow diet (SCD), HFD, HFD + GEN, HFD + CGA, and HFD + GEN + CGA for 10 weeks.&#x0D; Results: The findings indicated that single treatment with GEN or CGA, and with a stronger effect of GEN+CGA combined treatment, decreased body weight gain and improved glucose intolerance. Moreover, following treatment with GEN and CGA alone or in combination with further effect, the level of plasma and muscle triglyceride (TG) were reduced. Furthermore, the combination therapy of GEN and CGA with greater efficacy than the single treatments, could decrease several oxidative stress markers in the skeletal muscle. Treatment with GEN and CGA alone or in combination could increase the expression of NF-E2–related factor 2 (Nrf2), heme oxygenase-1 (HO-1), and NAD(P): Quinone Oxidoreductase 1 (NQO1).&#x0D; Conclusion: The data of this study suggest that the combination of GEN and CGA might ameliorate insulin resistance and reduce oxidative stress in the skeletal muscle of mice fed HFD.
