#805 Successful application of DALI for extracorporeal hemocorrection in a patient with LDL cholesterol serum levels (case study)

Abstract Background and Aims Plasma lipoidosis type 4 (PLD4) is a rare hereditary disease characterized by disorders of fat metabolism in the body. PLD4 occurs rare in the general population. The exact frequency of occurrence is unknown, as it depends on hereditary factors in a particular population. The relevance of the disease lies in its rarity and potential association with various complications. Patients with PLD4 have decreased levels of low-density cholesterol (LDL) and increased levels of triglycerides in the blood, which can lead to the development of atherosclerosis and other cardiovascular diseases. Plasma lipoidosis type 4 requires further researches for better understanding of its epidemiology, mechanisms of development and possible treatment strategies. In this case, we describe the case of a patient with type 4 plasmatic lipoidosis who was treated with the DALI (Direct Adsorption of Lipoproteins) technique. Anticoagulation is initiated with heparin and maintained by ACT. This technique is accompanied by decreasing the level of LDL and Lp (a) without decreasing the level of HDL and fibrinogen. The pore sizes of the polyacrylamide bed are small enough to avoid the removal of red blood cells and platelets. Activation of leukocytes and complement is minimal and clinically insignificant. Depending on the initial level of lipidemia during this procedure, it is possible to select the appropriate adsorber (DALI-500, -750, -1000). Methods of extracorporeal correction of lipid metabolism disorders should be widely introduced into healthcare practice. It should be noted that during DALI apheresis, the fibrinogen level does not decrease so sharply and is not accompanied by changes in erythrocyte aggregation. (Richter W. O., 2003). Aim of study The purpose of our study was to evaluate the effectiveness of using DALI (Direct Adsorption of Lipoproteins) in a patient with type 4 plasmatic lipoidosis. Method Patient N., 67 years old, diagnosed with IHD. Angina pectoris FC 2. Plasma lipoidosis type 4, hyperbetalipoproteinemia by autosomal dominant type of inheritance. Cysts of both kidneys. In 1997, diagnosed with: plasma lipoidosis type 4, hyperbetalipoproteinemia by an autosomal dominant type of inheritance. The plasmapheresis sessions were recommended against the increased lipid metabolism indexes. The patient regularly receives antilipidemic therapy and plasmapheresis sessions up to 2 times a year. The patient is admitted with complaints of fatigue and general weakness. According to the patient's ambulatory card, discharge summaries: CREA - 147 µmol/l, UREA – 6.3 mmol/l. GFR – 34 ml/min/1.73 m2. Total bilirubin - 9 µmol/l, direct bilirubin - 3 µmol/l. Considering the severity of the condition and the activity of the main diagnosis, a procedure with the DALI technique was started. During the hospitalization period, 3 procedures were performed, the whole of them were tolerated satisfactorily. The general condition is of moderate severity. Consciousness is clear. Hemodynamics is stable. Urination is free and painless. Diuresis is adequate. Results Hemodynamics: when connected - blood pressure – 120/82 mm Hg, heart rate – 61 beats/min. When disconnected, the patient's condition is the same, hemodynamics - blood pressure – 119/59 mm Hg, heart rate – 65 beats / min. Conclusion The usage of the apheresis method with the DALI system can effectively reduce the level of low-density lipoprotein (LDL) and Lp (a), while maintaining the content of high-density lipoprotein (HDL) and fibrinogen at a constant level. This reduction in LDL concentrations has the potential to reduce patients' risk of developing cardiovascular disease and the mortality from it.

Associations of multiple hydroxy-polycyclic aromatic hydrocarbons with serum levels of lipids in the workers from coking and non-ferrous smelting industries

Epidemiological evidence indicates that exposure to polycyclic aromatic hydrocarbons (PAHs) is associated with certain metabolic diseases. However, the relationship between PAHs and serum lipid profiles in exposed subjects remain unknown. Herein, the associations of multiple (8) urinary hydroxylated PAHs (OH-PAHs) in workers of coking (n = 655) and non-ferrous smelting (n = 614) industries with serum lipid levels (marking lipid metabolism) were examined. Multivariable linear regression, Bayesian kernel machine regression, and quantile g-computation were used. Most urinary OH-PAHs were significantly higher (p < 0.001) in coking workers than in non-ferrous smelting workers. In workers of both industries, OH-PAH exposure was associated with elevated levels of serum total cholesterol, total triglyceride, and low-density lipoprotein, as well as reduced high-density lipoprotein levels. Specifically, urinary 4-hydroxyphenanthrene was significantly positively associated with serum total cholesterol, total triglyceride, and low-density lipoprotein levels in non-ferrous smelting workers; however, the completely opposite association of 4-hydroxyphenanthrene with these lipid levels was observed in coking workers. The results of this pioneering examination suggest that exposure to OH-PAHs may contribute to dyslipidemia in coking and non-ferrous smelting workers, and distinct patterns of change were observed. Further prospective studies involving larger sample sizes are needed to further validate the findings.

Lipidomics study of Liujunzi decoction in hyperlipidemia rats with spleen deficiency based on UPLC-Q-TOF/MS

Hyperlipidemia refers to the abnormal levels of triglyceride (TG), total cholesterol (TC), low-density lipoprotein (LDL-C) and high-density lipoprotein (HDL-C) in peripheral blood circulation. It is a predominant risk factor underlying cardiovascular and cerebrovascular diseases, including coronary heart disease and atherosclerosis. Furthermore, it is also one of the most prevalent chronic diseases globally. Liujunzi Decoction is the basic prescription for the treatment of spleen and stomach diseases. It can tonify the spleen and qi, remove dampness, and reduce turbidity. Moreover, it is also clinically used for the treatment of spleen deficiency hyperlipidemia. However, its metabolites and therapeutic effect on spleen deficiency hyperlipidemia have not been comprehensively determined in vitro and in vivo. This study established a rat model of spleen deficiency hyperlipidemia by inducing starvation and satiety disorders, exhaustion swimming, and intragastric administration of the fat emulsion. To identify related metabolite changes and serum lipid composition, UPLC-Q-TOF-MS, PCA, and OPLS-DA lipidological methods were performed. The results demonstrated significant changes in rat's signs during the modeling process, which were consistent with the criteria for the syndrome differentiation of spleen deficiency in traditional Chinese medicine. Furthermore, this study identified 100 potential biomarkers in rat serum, of which 52 were associated with lipid synthesis, such as LPC, PC, PI, PE, PA, Cer, SM, etc. The pathways involved were glycerol phospholipid, sphingomyelin, and glycerol ester metabolisms. After the Liujunzi decoction intervention, 56 potential biomarkers were observed in the high-dose group, alleviating the metabolic spectrum imbalance by reducing metabolite levels. In addition, metabolic pathway disturbances were markedly improved. This study provides references for future studies on Liujunzi decoction and furnishes essential data for assessing the relationships between chemical constituents and pharmacological activities of Liujunzi decoction.

Impact of Heavy Metal Pollution on Oxidized Low-density Lipoprotein Levels among Car Maintenance Workshop Workers

This study aimed to evaluate the relationship between heavy metal pollution and oxidized low-density lipoprotein (OxLDL) among workers in car maintenance workshops in Baghdad, Iraq. Blood samples were collected from 70 male workers, including car maintenance and vehicle painting workers, along with a control group of healthy males. The levels of heavy metals, specifically cadmium (Cd) and lead (Pb), as well as OxLDL and the marker of lipid peroxidation, malondialdehyde (MDA), were measured. The results revealed a significant increase in the level of Pb in the blood of workers compared to the control group, whereas Cd levels did not exhibit a significant difference. Furthermore, both groups of workers exhibited significantly elevated levels of OxLDL compared to the control group. Additionally, the MDA level was significantly increased across all the study groups. Correlation analysis demonstrated positive associations between OxLDL levels and the extent of Pb and Cd pollution in the car maintenance worker group. These findings indicate an increased risk of developing cardiovascular diseases (CVDs) among workers in car maintenance workshops due to exposure to heavy metals. The observed elevation in the levels of OxLDL and lipid peroxidation markers underscores the potential health issues associated with occupational exposure to these polluted environments.

IMPACT OF CORONARY ARTERY DISEASE ON STEATOTIC LIVER DISEASE PROGRESSION

Introduction. Metabolic dysfunction-associated steatotic liver disease and coronary artery disease often exacerbate each other, leading to a more severe course of both conditions. The aim of this study is to evaluate the role of coronary artery disease in dislipidemia and liver fibrosis progression in patients with metabolic dysfunction-associated steatotic liver disease. Materials and methods. Forty-six patients with metabolic dysfunction-associated steatotic liver disease were examined. Patients were divided into two groups based on the presence of concomitant coronary artery disease: group I (n=24) included patients with both metabolic dysfunction-associated steatotic liver disease and coronary artery disease, while group II (n=22) included patients with metabolic dysfunction-associated steatotic liver disease only. A third group (Group III) comprised healthy individuals. Specific lipid metabolism parameters, obesity stage, alanine aminotransferase (ALT), aspartate aminotransferase (AST), γ-glutamyl transpeptidase (GGT) activity, and platelet count were examined. Fibrosis stage was evaluated using the FIB-4 score. The findings obtained were statistically processed. Results. Arterial hypertension was more prevalent in patients with metabolic dysfunction-associated steatotic liver disease and concomitant coronary artery disease. In group I, arterial hypertension was observed in 95.8% of cases, whereas in group II, it was observed in 40.9% of cases (χ2=16.35, p=0.00005). Patients with metabolic dysfunction-associated steatotic liver disease exhibited elevated levels of total cholesterol, low-density lipoproteins, and triglycerides, leading to an increased atherogenic index. Conversely, high-density lipoprotein levels were decreased (p&gt;0.05). The degree of fibrosis according to the FIB-4 score was 1.45 times higher in patients with metabolic dysfunction-associated steatotic liver disease and concomitant coronary artery disease compared to those without coronary artery disease.

Prevalence of dyslipidemia, hypertension and diabetes among tribal and rural population in a south Indian forested region.

While NCDs are in rise globally, tribal and rural populations residing near to reserve forests with limited exposure to modern lifestyles may bear a unique burden. This study investigates the prevalence and risk factors of hypertension, diabetes, and dyslipidemia among these communities. We conducted a cross-sectional study between 2018 and 2020 in the forest-dwelling population of Chamarajanagar, India. Using multistage stratified sampling based on caste and remoteness, we enrolled 608 participants aged over 18 years, including 259 non-tribal and 349 tribal individuals. Data collection includes the administration of STEPS questionnaire and measurement of fasting blood sugar, lipid levels, and blood pressure. The prevalence of diabetes, hypertension, and dyslipidemia were 4.6%, 28.8%, and 85.7%, respectively, among the study population. We also found abnormal levels of low-density lipoprotein (LDL), high-density lipoprotein (HDL), Triglycerides (TGA), Total cholesterol (TC), and very low-density lipoprotein (VLDL)in 4.9%, 82.4%, 22.7%, 5.8%, and 7.4% of participants, respectively. Significant differences were observed in diabetes, LDL abnormality, TGA abnormality, VLDL abnormality, and TC abnormality, but not in hypertension, dyslipidemia, or HDL abnormality, across the Socio Geographic Discrimination Index. We found a significant difference in diabetes and HDL abnormality, but not in hypertension, dyslipidemia, LDL abnormality, TGA abnormality, TC abnormality, or VLDL abnormality, between tribal and non-tribal populations living in the forest-dwelling area. Waist circumference was a significant independent predictor of diabetes among tribal participants, while wealth index, age, and waist circumference were significant predictors of hypertension. There were no significant predictors for dyslipidemia among tribal participants. Our study suggests that tribal population living in a remote area are at a lower risk of developing diabetes compared to non-tribal populations living in the same geographic area. However, the prevalence of hypertension and dyslipidemia among tribal populations remains high and comparable to that of the general population.

Effect of apremilast on cardiovascular risk in psoriasis patients in comparison with methotrexate

Background: Psoriasis is a common chronically relapsing inflammatory disorder with cutaneous and rheumatologic manifestations characterized by an increase in risk of cardiovascular diseases. Chronic inflammation in psoriatic patients predisposes them to cardiovascular morbidity. This study was done to compare the change in cardiovascular risk factors who are taking apremilast and methotrexate. Aims and objectives: The aims of this study were as follows: (1) To evaluate the effect on biochemical parameters pertaining to cardiovascular risk in psoriasis patients after 12 weeks of treatment with apremilast in comparison with methotrexate. (2) To compare the efficacy of methotrexate with apremilast in treating chronic plaque psoriasis. Materials and Methods: This hospital-based prospective cohort study included 40 newly diagnosed cases of psoriasis who were divided into two groups – group A (receiving methotrexate) and group B (receiving apremilast) and were assessed at baseline and after 12 weeks. The outcome was assessed on the basis of psoriasis area and severity index score and the biochemical parameters. Results: We found a significant decrease in triglycerides, high sensitivity C-reactive protein, and low-density lipoprotein levels in psoriasis patients taking methotrexate and high-density lipoprotein in the apremilast group. Conclusion: On comparing the two drugs, methotrexate is considered to have more cardioprotective action.

Regulatory patterns of Chinese patent medicine for lipid metabolism disorders in patients with type 2 diabetes mellitus complicated by ischemic stroke: A systematic review and network meta-analysis.

To investigate the regulatory patterns of Chinese patent medicine (CPM) interventions on lipid metabolism disorders in patients with type 2 diabetes mellitus (T2DM) complicated by ischemic stroke. Two researchers independently searched 8 major databases and created a comprehensive database containing all randomized controlled trials (RCTs) that investigated the application of "blood-activating and stasis-removing" CPM in the treatment of stroke combined with T2DM until October 1, 2022. The collected data were compiled and organized in Excel. Quality assessment was performed using the Cochrane 5.3 bias risk assessment tool, and the network meta-analysis was conducted using R software. A total of 12 articles were included in the final analysis, covering 4 types of CPM: Naoxintong Capsules (NXT), Tongmai Jiangtang Capsules, Tongxinluo Capsules (TXL), and Yindan Xinnaotong Soft Capsules. Among these, CPM formulations containing herbs with blood-activating and stasis-removing properties were the most commonly used. The results of the network meta-analysis are as follows: (1) the combination of 3 CPM formulations showed superior efficacy in improving total cholesterol levels compared to conventional Western medicine treatment (CT). In particular, Yindan Xinnaotong Soft Capsules + CT (surface under the cumulative ranking curve [SUCRA] = 97.24%) demonstrated the highest efficacy, followed by NXT + CT (SUCRA = 66.23%), and then TXL + CT (SUCRA = 55.16%). (2) TXL + CT treatment exhibited the most promising efficacy in improving triglyceride levels (P < .05), while the effects of the other 3 CPM formulations were not statistically significant. (3) In terms of improving low-density lipoprotein levels, NXT + CT (SUCRA = 82.27%) showed better efficacy than TXL + CT (SUCRA = 73.99%), while the effects of the other 2 CPM formulations were not statistically significant. (4) The combination of CPM formulations and CT resulted in a lower incidence of adverse reactions compared to CT (P < .05). The treatment of patients with T2DM complicated by ischemic stroke commonly involved the use of "blood-activating and stasis-removing" herbal medicines. These herbal medicines have shown effectiveness in regulating patients' blood lipid levels. However, it is crucial to acknowledge that the analysis was influenced by variations in the number and quality of RCTs involving different CPM formulations. Therefore, additional validation through large-scale, high-quality RCT studies is required.

Clinical Biomarkers of Dyslipidemia in Diabetes Mellitus Type II Patients

Background. This study aims to comparatively investigate the clinical biomarkers of diabetic dyslipidemia in type II diabetes mellitus (TIIDM) patients and healthy controls with no clinical diabetic history. Method. A cross-sectional study was conducted on 100 TIIDM patients age-matched with 100 control subjects. They were evaluated from January 2021 to July 2022 in Narowal, Pakistan. Various biomarkers including total cholesterol (TL), low-density lipoprotein (LDL), high-density lipoprotein (HDL), and triglycerides were measured for each subject. Results. The results showed significantly higher levels of TC (238 ± 30 mg/dl), triglycerides (201 ± 72 mg/dl), and LDL (141 ± 47 mg/dl) in TIIDM patients as compared to control groups’ levels of TC (167 ± 23 mg/dl), triglycerides (175 ± 75 mg/dl), and LDL (95 ± 30 mg/dl). However, HDL level was significantly lower (46 ± 21 mg/dl) in TIIDM patients as compared to control group (54 ± 27 mg/dl). Conclusion. The clinical biomarkers of dyslipidemia are effective risk predictors for cardiovascular diseases in low-income countries such as Pakistan.

Clustering Identifies Subtypes With Different Phenotypic Characteristics in Women With Polycystic Ovary Syndrome.

Hierarchical clustering (HC) identifies subtypes of polycystic ovary syndrome (PCOS). This work aimed to identify clinically significant subtypes in a PCOS cohort diagnosed with the Rotterdam criteria and to further characterize the distinct subtypes. Clustering was performed using the variables body mass index (BMI), luteinizing hormone (LH), follicle-stimulating hormone, dehydroepiandrosterone sulfate, sex hormone-binding globulin (SHBG), testosterone, insulin, and glucose. Subtype characterization was performed by analyzing the variables estradiol, androstenedione, dehydroepiandrosterone, cortisol, anti-Müllerian hormone (AMH), total follicle count (TFC), lipid profile, and blood pressure. Study participants were girls and women who attended our university hospital for reproductive endocrinology screening between February 1993 and February 2021. In total, 2502 female participants of European ancestry, aged 13 to 45 years with PCOS (according to the Rotterdam criteria), were included. A subset of these (n = 1067) fulfilled the National Institutes of Health criteria (ovulatory dysfunction and hyperandrogenism). Main outcome measures included the identification of distinct PCOS subtypes using cluster analysis. Additional clinical variables associated with these subtypes were assessed. Metabolic, reproductive, and background PCOS subtypes were identified. In addition to high LH and SHBG levels, the reproductive subtype had the highest TFC and levels of AMH (all P < .001). In addition to high BMI and insulin levels, the metabolic subtype had higher low-density lipoprotein levels and higher systolic and diastolic blood pressure (all P < .001). The background subtype had lower androstenedione levels and features of the other 2 subtypes. Reproductive and metabolic traits not used for subtyping differed significantly in the subtypes. These findings suggest that the subtypes capture distinct PCOS causal pathways.

Structural and functional alteration of the gut microbiota in elderly patients with hyperlipidemia.

To investigate the structure, composition, and functions of the gut microbiota in elderly patients with hyperlipidemia. Sixteen older patients diagnosed with hyperlipidemia (M group) and 10 healthy, age-matched normal volunteers (N group) were included. These groups were further subdivided by sex into the male normal (NM, n = 5), female normal (NF, n = 5), male hyperlipidemia (MM, n = 8), and female hyperlipidemia (MF, n = 8) subgroups. Stool samples were collected for high-throughput sequencing of 16S rRNA genes. Blood samples were collected for clinical biochemical index testing. Alpha- and beta-diversity analyses revealed that the structure and composition of the gut microbiota were significantly different between the M and N groups. The relative abundances of Bacteroides, Parabacteroides, Blautia, Peptococcus, and Bifidobacterium were significantly decreased, while those of Lactobacillus, Helicobacter, and Desulfovibrio were significantly higher in the M group. There were also significant sex-related differences in microbial structure between the NM and NF groups, and between the MM and MF groups. Through functional prediction with PICRUSt 2, we observed distinct between-group variations in metabolic pathways associated with the gut microbiota and their impact on the functionality of the nervous system. Pearson's correlation coefficient was used as a distance metric to build co-abundance networks. A hypergeometric test was used to detect taxonomies with significant enrichment in specific clusters. We speculated that modules with Muribaculaceae and Lachnospiraceae as the core microbes play an important ecological role in the intestinal microbiota of the M group. The relative intestinal abundances of Agathobacter and Faecalibacterium in the M group were positively correlated with serum triglyceride and low-density lipoprotein levels, while the relative abundance of Bifidobacterium was negatively correlated with the serum lipoprotein a level.

Dyslipidemia among adult HIV patients on antiretroviral therapy and its association with age and body mass index in Ethiopia: A systematic review and meta-analysis.

Dyslipidemia is a common public health problem in people living with human immunodeficiency virus (HIV) who are receiving antiretroviral therapy and increases the risk of cardiovascular disease. Although evidence indicates that the prevalence of dyslipidemia is high, estimated pooled data are not well documented. Therefore, we aimed to estimate the pooled prevalence of dyslipidemia in adult people living with HIV receiving antiretroviral therapy in Ethiopia. We conducted a systematic review and meta-analysis of the literature. The following databases and grey literature were searched: PubMed, WorldCat, ScienceDirect, DOAG, African Journals Online, Google Scholar, and African Index Medicine. We included all comparative epidemiological studies that reported the prevalence of high concentration of total cholesterol, triglycerides, and low density lipoprotein, and low concentration of high density lipoprotein cholesterol that were published between January 2003 and July 2023. The random effects model was used to pool the outcome of interest. Additionally, subgrouping, sensitivity analyses, and funnel plots were performed. R software Version 4.2.1 was used for statistical analysis. Seventeen studies with a total of 3929 participants were included in the meta-analysis. The pooled prevalence of dyslipidemia, high total cholesterol, high triglyceride, elevated level of low density lipoprotein and low level of high density lipoprotein cholesterol were 69.32% (95% CI: 63.33, 74.72), 39.78% (95%CI: 32.12, 47.96), 40.32% (95%CI: 34.56, 46.36), 28.58% (95%CI: 21.81, 36.46), and 36.17% (95%CI: 28.82, 44.24), respectively. Age and body mass index were associated with high total cholesterol, triglyceride, and low-density lipoprotein cholesterol levels. The authors concluded that the prevalence of dyslipidemia in Ethiopia is high in people living with HIV receiving antiretroviral therapy. Early detection of dyslipidemia and its integration into treatment are essential for preventing cardiovascular disease. Protocol registered with PROSPERO (CRD42023440125).

Weight loss, glycolipid profile changes in type 2 diabetes patients after esophagectomy: a propensity score matching analysis

BackgroundType 2 diabetes mellitus (T2DM) is a common co-morbidity in patients who receive esophagectomy and has unfavorable effects on glucose and lipid metabolism in patients. This study examines how weight and glycolipid metabolism change in patients with T2DM following esophagectomy.MethodsThis retrospective, one-center, observational analysis with a propensity score matching analysis (PSM) included 114 patients who underwent esophageal surgery in the Department of Cardiothoracic Surgery, the 900th Hospital of Joint Logistic Support Force from 2017 to 2020, which were separated into T2DM group and Non-T2DM group. Weight, body mass index (BMI), fasting plasma glucose (FPG), triglycerides (TG), total cholesterol (TC), high-density lipoprotein (HDL), and low-density lipoprotein (LDL) were measured and analyzed before and after the operation.ResultsTwo groups showed similar reductions in weight and BMI after surgery. In the T2DM group, weight decreased from 63.10(10.31) before surgery to 55.10(11.60) kg at 6 months (P < 0.001) with BMI decreasing from 22.67 (2.90) to 19.77 (3.48); While in the Non-T2DM group, weight decreased from 61.42 (8.46) to 53.19 (9.26) kg at 6 months after surgery with BMI decline from 22.49 (2.77) before operation to 19.45 (3.08) at 6 months after surgery. Fasting plasma glucose levels showed a significant decrease (P = 0.035) in the T2DM group at a six-month point of 7.00 (2.21) mmol/L compared to preoperative levels of 7.67 (2.32) mmol/L. HDL levels increased significantly in the Non-T2DM group at six months postoperatively at 1.52 (0.05) with P < 0.001 compared to preoperative levels of 1.22(0.04) mmol/L. TG, LDL, and TC levels decreased significantly in both groups from the preoperative to the 6-month point.ConclusionsEsophagectomy induces weight loss in T2DM and Non-T2DM groups, improves long-term glucose metabolism in the T2DM group, and enhances lipid metabolism in both groups. Further research is needed to understand their mechanisms.

The Response of the Amputee Athlete Heart to Chronic Core Exercise: A Study on Hematological and Biochemical Parameters, and N-Terminal Pro Brain Natriuretic Peptide.

Background and Objectives: mortality and morbidity due to cardiovascular causes are frequently experienced in amputees. Research on the effects of chronic exercise on biomarkers and cardiac damage indicators in these individuals is limited. The aim of this study was to investigate the effects of a core training program on brain natriuretic-related peptide, as well as hematological and biochemical parameters in amputee soccer players. Materials and Methods: The participants were randomly allocated to the following two groups: a core exercise group (CEG) and a control group (CG). While the CG continued routine soccer training, the CEG group was included in a core exercise program different from this group. During the study, routine hemogram parameters of the participants, various biochemical markers, and the concentration of brain natriuretic-related peptide (NT-pro-BNP) were analyzed. Results: after the training period, notable improvements in various hematological parameters were observed in both groups. In the CEG, there were significant enhancements in red blood cell count (RBC), hematocrit (HCT), mean corpuscular hemoglobin concentration (MCHC), and mean corpuscular hemoglobin (MCH) values. Similarly, the CG also showed substantial improvements in RBC, HCT, mean corpuscular volume (MCV), MCHC, MCH, red cell distribution width-standard deviation (RDW-SD), platelet-to-lymphocyte ratio (PLCR), mean platelet volume (MPV), and platelet distribution width (PDW). Moreover, in the CEG, serum triglycerides (TG) and maximal oxygen uptake (MaxVO2) exhibited significant increases. Conversely, TG levels decreased in the CG, while high-density lipoprotein (HDL), low-density lipoprotein (LDL), and MaxVO2 levels demonstrated substantial elevations. Notably, the N-terminal pro-brain natriuretic peptide (BNP) levels did not undergo significant changes in either the CEG or the CG following the core exercise program (p > 0.05). However, in the CEG, a meaningful positive correlation was observed between NT-pro-BNP and creatine kinase (CK) levels before and after the core exercise program. Conclusions: the findings emphasized the potential benefits of core training in enhancing specific physiological aspects, such as erythrocyte-related parameters and lipid metabolism, as well as aerobic capacity. Furthermore, the observed correlation between NT-pro-BNP and CK levels in the CEG provides intriguing insights into the unique physiological adaptations of amputee athletes.

The effects of kettlebell training versus resistance training using the own body mass on physical fitness and physiological adaptations in obese adults: a randomized controlled trial

Aim of studyThis study aimed to explore the effects of different types of resistance training using kettlebells versus the own body mass, in comparison to a passive control, on key physical fitness and physiological parameters in young, obese adults.MethodsData from 60 sedentary, obese male college students, aged 17–26, were used for final analyses. Participants were randomly assigned to one of three groups: a control group (CG, n = 20, no training), a kettlebell resistance training group (KRTG, n = 20), or a bodyweight resistance training group (BWRTG, n = 20). Selected measures of physical fitness were tested using the 12-minutes run test, the push-up test, the sit-up test, and the sit-and-reach test. Physiological measures included vital capacity, resting and maximum heart rate (HRmax), mean arterial blood pressure, breath holding time, and respiratory rate. Biochemical variables were measured in the morning, in a fasted state, and comprised high and low density lipoprotein, total cholesterol, and triglycerides. The 12-weeks progressive KRTG and BWRTG were specifically tailored using sets, repetitions, and intensity levels.ResultsNotable findings include significant body fat reductions in BWRTG (p < 0.001; d = 1.53) and KRTG (p < 0.001; d = 1.43), and a substantial increase in VO2max for BWRTG (p < 0.001; d = 1.32) and KRTG (p < 0.001; d = 1.34) compared to CG. KRTG also showed significant improvements in vital capacity (p < 0.001; d = 1.61) and reductions in resting heart rate (p = 0.024, d = 1.05) and respiratory rate (p = 0.001, d = 1.55), with BWRTG showing similar trends (resting heart rate: p = 0.041, d = 1.35; respiratory rate: p = 0.001, d = 1.98). Both intervention groups significantly improved breath holding time (KRTG: p = 0.001, d = 1.58; BWRTG: p < 0.001, d = 1.98) and reduced total cholesterol and low-density lipoprotein levels compared to CG.ConclusionsThis study demonstrates that both KRTG and BWRTG are effective in improving body composition and selected fitness and physiological measures. Thus, resistance training using kettlebells or bodyweight training are recommended if the goal is to improve body composition and fitness in obese male adults.Trial RegistrationOSF, September, 28th 2023. https://doi.org/10.17605/OSF.IO/Z6Y9Gosf.io/2mb98

Serum Levels of Adiponectin Are Strongly Associated with Lipoprotein Subclasses in Healthy Volunteers but Not in Patients with Metabolic Syndrome.

Metabolic syndrome (MS) is a widespread disease in developed countries, accompanied, among others, by decreased adiponectin serum levels and perturbed lipoprotein metabolism. The associations between the serum levels of adiponectin and lipoproteins have been extensively studied in the past under healthy conditions, yet it remains unexplored whether the observed associations also exist in patients with MS. Therefore, in the present study, we analyzed the serum levels of lipoprotein subclasses using nuclear magnetic resonance spectroscopy and examined their associations with the serum levels of adiponectin in patients with MS in comparison with healthy volunteers (HVs). In the HVs, the serum levels of adiponectin were significantly negatively correlated with the serum levels of large buoyant-, very-low-density lipoprotein, and intermediate-density lipoprotein, as well as small dense low-density lipoprotein (LDL) and significantly positively correlated with large buoyant high-density lipoprotein (HDL). In patients with MS, however, adiponectin was only significantly correlated with the serum levels of phospholipids in total HDL and large buoyant LDL. As revealed through logistic regression and orthogonal partial least-squares discriminant analyses, high adiponectin serum levels were associated with low levels of small dense LDL and high levels of large buoyant HDL in the HVs as well as high levels of large buoyant LDL and total HDL in patients with MS. We conclude that the presence of MS weakens or abolishes the strong associations between adiponectin and the lipoprotein parameters observed in HVs and disturbs the complex interplay between adiponectin and lipoprotein metabolism.

GROWTH PERFORMANCE AND LIPID PROFILE OF ARCHACHATINA MARGINATA (GIANT AFRICAN LAND SNAIL) FED VARYING LEVELS OF RIPE EGGPLANT FRUITS BASED DIETS

The performance of African giant land snails (Archachatina marginata) fed ripe eggplant fruits was studied using eighty-four (84) juvenile (four months old) Archachatina marginata for eight (8) weeks. The study evaluated the snails' growth performance and lipid profile (total cholesterol, low-density lipoprotein, high-density lipoprotein and triglycerides). The snails were divided into four treatment groups, with twenty-one (21) snails per group in a completely randomized design (CRD). Treatments 1, 2, 3 and 4 had varying levels of ripe eggplant fruits at 0%, 5%, 10% and 15% inclusion levels respectively. Isocaloric and isonitrogenous feeds and water were provided ad libitum, while other management practices were strictly adhered to. The results showed no significant differences (P&gt;0.05) in growth performance across treatments. The results also revealed that total cholesterol decreased (P&lt;0.05) significantly as the levels of ripe eggplant fruits increased across treatments. There were no significant differences (P&gt;0.05) in low-density lipoprotein and triglycerides, while high-density lipoprotein differed (P&lt;0.05) significantly across treatments. The result also showed a linear increase in high-density lipoprotein ("good" cholesterol) as the levels of ripe eggplant fruits increased across treatments. Therefore, a 15% inclusion level of ripe eggplant fruits in the diet of Archachatina marginata reduces total cholesterol levels and increases high-density lipoprotein without any adverse effect on growth. The study recommends using ripe eggplant fruits to formulate diets for animals with high cholesterol content and high levels of low-density lipoprotein in their meat.

Nutritional Strategies to Mitigate Complications and Improve Long-Term Functionality of Autologous Arteriovenous Fistula Post Ultrasound and DSA Guided Balloon Dilation

This prospective cohort study evaluated the efficacy of omega-3 fatty acid supplementation on arteriovenous fistula patency and systemic inflammation in 220 hemodialysis patients undergoing ultrasound and digital subtraction angiography-guided balloon dilation. The participants were randomized into an intervention group receiving 2,000 mg of omega-3 fatty acids daily and a placebo group. The primary outcome measures were arteriovenous fistula patency at 12- and 24-months post-dilation, while secondary outcomes included thrombosis incidence, changes in inflammatory markers (c-reactive protein and interleukin-6), lipid profiles, and health-related quality of life (HRQoL). Results indicated a significant improvement in arteriovenous fistula patency in the omega-3 group at 24 months (80.9 vs. 68.2%, P &lt; 0.05). Additionally, there was a significant reduction in thrombosis rates (7.3 vs. 16.4%, P &lt; 0.05) and inflammatory markers (c-reactive protein and interleukin-6) in the omega-3 group compared to the placebo. Lipid profile analysis showed a decrease in total cholesterol and low-density lipoprotein levels with omega-3 supplementation, with significant changes at 12 months (P &lt; 0.05). HRQoL scores also improved significantly in the omega-3 group at both 12 and 24 months (P &lt; 0.05). These findings suggest that omega-3 fatty acids can enhance arteriovenous fistula functionality and reduce cardiovascular risk factors in hemodialysis patients. And its integration into standard care protocols for patients with arteriovenous fistulas would improve long-term outcomes.

It is Time to Screen for Homozygous Familial Hypercholesterolemia in the United States.

Homozygous familial hypercholesterolemia (HoFH) is an ultra-rare inherited condition that affects approximately one in 300,000 people. The disorder is characterized by extremely high, life-threatening levels of low-density lipoprotein (LDL) cholesterol from birth, leading to significant premature cardiovascular morbidity and mortality, if left untreated. Homozygous familial hypercholesterolemia is severely underdiagnosed and undertreated in the United States (US), despite guidelines recommendations for universal pediatric lipid screening in children aged 9-11. Early diagnosis and adequate treatment are critical in averting premature cardiovascular disease in individuals affected by HoFH. Yet, an unacceptably high number of people living with HoFH remain undiagnosed, misdiagnosed, and/or receive a late diagnosis, often after a major cardiovascular event. The emergence of novel lipid-lowering therapies, along with the realization that diagnosis is too often delayed, have highlighted an urgency to implement policies that ensure timely detection of HoFH in the US. Evidence from around the world suggests that a combination of universal pediatric screening and cascade screening strategies constitutes an effective approach to identifying heterozygous familial hypercholesterolemia (HeFH). Nevertheless, HoFH and its complications manifest much earlier in life compared to HeFH. To date, little focus has been placed on the detection of HoFH in very young children and/or infants. The 2023 Updated European Atherosclerosis Society Consensus Statement on HoFH has recommended, for the first time, broadening pediatric guidelines to include lipid screening of newborn infants. Some unique aspects of HoFH need to be considered before implementing newborn screening. As such, insights from pilot studies conducted in Europe may provide some preliminary guidance. Our paper proposes a set of actionable measures that states can implement to reduce the burden of HoFH. It also outlines key research and policy gaps that need to be addressed in order to pave the way for universal newborn screening of HoFH in the US.

Causal association of plasma circulating metabolites with nephritis: a Mendelian randomization study.

Nephritis is a pivotal catalyst in chronic kidney disease (CKD) progression. Although epidemiological studies have explored the impact of plasma circulating metabolites and drugs on nephritis, few have harnessed genetic methodologies to establish causal relationships. Through Mendelian randomization (MR) in two substantial cohorts, spanning large sample sizes, we evaluated over 100 plasma circulating metabolites and 263 drugs to discern their causal effects on nephritis risk. The primary analytical tool was the inverse variance weighted (IVW) analysis. Our bioinformatic scrutiny of GSE115857 (IgA nephropathy, 86 samples) and GSE72326 (lupus nephritis, 238 samples) unveiled anomalies in lipid metabolism and immunological characteristics in nephritis. Thorough sensitivity analyses (MR-Egger, MR-PRESSO, leave-one-out analysis) were undertaken to verify the instrumental variables' (IVs) assumptions. Unique lipoprotein-related molecules established causal links with diverse nephritis subtypes. Notably, docosahexaenoic acid (DHA) emerged as a protective factor for acute tubulointerstitial nephritis (ATIN) (OR1 = 0.84, [95% CI 0.78-0.90], p1 = 0.013; OR2 = 0.89, [95% CI 0.82-0.97], p2 = 0.007). Conversely, multivitamin supplementation minus minerals notably increased the risk of ATIN (OR = 31.25, [95% CI 9.23-105.85], p = 0.004). Reduced α-linolenic acid (ALA) levels due to lipid-lowering drugs were linked to both ATIN (OR = 4.88, [95% CI 3.52-6.77], p < 0.001) and tubulointerstitial nephritis (TIN) (OR = 7.52, [95% CI 2.78-20.30], p = 0.042). While the non-renal drug indivina showed promise for TIN treatment, the use of digoxin, hydroxocobalamin, and liothyronine elevated the risk of chronic tubulointerstitial nephritis (CTIN). Transcriptome analysis affirmed that anomalous lipid metabolism and immune infiltration are characteristic of IgA nephropathy and lupus nephritis. The robustness of these causal links was reinforced by sensitivity analyses and leave-one-out tests, indicating no signs of pleiotropy. Dyslipidemia significantly contributes to nephritis development. Strategies aimed at reducing plasma low-density lipoprotein levels or ALA supplementation may enhance the efficacy of existing lipid-lowering drug regimens for nephritis treatment. Renal functional status should also be judiciously considered with regard to the use of nonrenal medications.
