Abstract Background Lipid disequilibrium and systemic inflammation are reported to correlate with tumorigenesis and development of colorectal cancer (CRC). We construct the novel biomarker cholesterol-to-lymphocyte ratio (CLR) to reflect the synergistic effect of cholesterol metabolism and inflammation on CRC outcomes. This study aims to investigate the clinical significance of CLR and establish a prognostic model for CRC. Methods Our study retrospectively enrolled 223 CRC patients who underwent curative surgical resection. The Kaplan-Meier method was employed to estimate the overall survival (OS) rates, and the association between serological biomarkers and survival was assessed with a log-rank test. Cox proportional hazard regression was applied in the univariate and multivariate analyses to identify independent prognostic factors, which were then used to develop a predictive nomogram model for OS in CRC. The nomogram was evaluated by the C-index, receiver operator characteristic curve (ROC) analysis, and calibration plot. All cases were grouped into three stratifications according to the total risk points calculated from the nomogram, and the difference in OS between them was assessed with the Kaplan-Meier method. Results At the end of the study, death occurred in 47 (21%) cases. Patients with low CLR (< 3.23) had significantly prolonged survival (P < 0.001). Multivariate analyses revealed that N stage (P < 0.001), harvested lymph nodes (P = 0.021), and CLR (P = 0.005) were independent prognostic factors for OS and a prognostic nomogram was established based on these variables. The nomogram showed good calibration and predictive performance with a superior C-index than TNM stage (0.755 (0.719–0.791) vs. 0.663 (0.629–0.697), P = 0.001). Patients of different risk stratifications based on the total score of nomogram showed distinct survival (P < 0.001). Conclusions The nomogram based on CLR and other clinical features can be used as a potentially convenient and reliable tool in predicting survival in patients with CRC.

IntroductionIsoliquiritigenin, one of the components in the root of Glycyrrhiza glabra L., is a member of the flavonoids, which are known to have an anti-tumor activity in vitro and in vivo. HMG-CoA reductase inhibitors, called statins, are used to reduce the risk of heart disease by lowering blood cholesterol levels.Material and methodsHMG-CoA Reductase activity according to the method described by Takahashi S. et al. The structure of human HMG-COA reductase in the resolution of 2.22 Å with X-RAY diffraction method (PDB ID: 1HWK) was obtained from the PDB database.ResultsIn our study, inhibition result of Isoliquiritigenin on HMG-CoA reductase showed lower value IC50 = 193.77±14.85 µg / mL. For a better understanding of biological activities and interactions, the molecular docking study was accomplished. The results of molecular docking revealed that isoliquiritigenin with a docking score of -6.740 has a strong binding affinity to the HMG-COA reductase. Therefore, this compound could be considered as a potential inhibitor for the enzyme. Also, the properties of Isoliquiritigenin against common human pancreatic acinar cell tumor cell lines i.e. 266-6, TGP49, and TGP47 were evaluated.ConclusionsThe treated cells with Isoliquiritigenin were assessed by MTT assay for 48h about the cytotoxicity and anti-human pancreatic acinar cell tumor properties on normal (HUVEC) and human pancreatic acinar cell tumor cell lines i.e. 266-6, TGP49, and TGP47. The IC50 of Isoliquiritigenin were 262, 389, and 211 µg/mL against 266-6, TGP49, and TGP47 cell lines, respectively.

Abstract Background The major cause of morbidity and mortality in diabetes is cardiovascular disease, which is exacerbated by the presence of hypertension. Therefore, proper control of BP in diabetic hypertensive patients is essential. Few studies have specifically investigated the prognostic significance of central BP in Egyptian populations with diabetes and hypertension and its relation with cardiovascular outcome. This study aims to evaluate relation between central BP and diabetic composite cardiovascular complications. Results Diabetic patients with CVD were significantly older (p value < 0.01), obese (p value < 0.01) with long duration of diabetes (p value < 0.001) and had significantly higher peripheral and central systolic and diastolic BP and higher AIx@75(p values < 0.01) than those without CVD. Regarding the metabolic parameters, they had significantly higher fasting blood glucose, HbA1c, and higher blood cholesterol levels (p values < 0.001), higher LDL (p value < 0.01), triglycerides levels (p value = 0.014), and microalbuminuria (p value = 0.028). Logistic regression analysis found increased BMI, central systolic BP, and AIx@75 were independent predictors of composite CVD (p values < 0.05). Conclusions There is a pattern of favorability towards central rather than peripheral BP indices to predict the occurrence of CVD in diabetic patients.

Consumption of lipid-rich foods can increase the blood cholesterol content. β-glucans have hypocholesterolemic effect. However, subtle changes in their molecular branching can influence bioactivity. Therefore, a comparative investigation of the cholesterol-lowering potential of two β-glucans with different branching patterns and a cholesterol-lowering drug, namely simvastatin was undertaken employing the zebrafish (Danio rerio) model of diet-induced hypercholesterolemia. Fish were allocated to 5 dietary treatments; a control group, a high cholesterol group, two β-glucan groups, and a simvastatin group. We investigated plasma total cholesterol, LDL and HDL cholesterol levels, histological changes in the tissues, and explored intestinal transcriptomic changes induced by the experimental diets. Dietary cholesterol likely caused the suppression of endogenous cholesterol biosynthesis, induced dysfunction of endoplasmic reticulum and mitochondria, and altered the histomorphology of the intestine. The two β-glucans and simvastatin significantly abated the rise in plasma cholesterol levels and restored the expression of specific genes to alleviate the endoplasmic reticulum-related effects induced by the dietary cholesterol. Furthermore, the distinct patterns of transcriptomic changes in the intestine elicited by the oat and microalga β-glucans impacted processes such as fatty acid metabolism, protein catabolic processes, and nuclear division. Oat and microalgal β-glucans also altered the pattern of lipid deposition in the liver. Our study provides insights into the effectiveness of different β-glucans to alleviate dysfunctions in lipid metabolism caused by dietary cholesterol.

ObjectiveThe human gut fungal community, known as the mycobiome, plays a fundamental role in the gut ecosystem and health. Here we aimed to investigate the determinants and long-term stability of gut mycobiome among middle-aged and elderly adults. We further explored the interplay between gut fungi and bacteria on metabolic health.DesignThe present study included 1244 participants from the Guangzhou Nutrition and Health Study. We characterised the long-term stability and determinants of the human gut mycobiome, especially long-term habitual dietary consumption. The comprehensive multiomics analyses were performed to investigate the ecological links between gut bacteria, fungi and faecal metabolome. Finally, we examined whether the interaction between gut bacteria and fungi could modulate the metabolic risk.ResultsThe gut fungal composition was temporally stable and mainly determined by age, long-term habitual diet and host physiological states. Specifically, compared with middle-aged individuals, Blastobotrys and Agaricomycetes spp were depleted, while Malassezia was enriched in the elderly. Dairy consumption was positively associated with Saccharomyces but inversely associated with Candida. Notably, Saccharomycetales spp interacted with gut bacterial diversity to influence insulin resistance. Bidirectional mediation analyses indicated that bacterial function or faecal histidine might causally mediate an impact of Pichia on blood cholesterol.ConclusionWe depict the sociodemographic and dietary determinants of human gut mycobiome in middle-aged and elderly individuals, and further reveal that the gut mycobiome may be closely associated with the host metabolic health through regulating gut bacterial functions and metabolites.

Purpose This study aims to assess dietary intake and prevalence of metabolic syndrome (MetS) among tanker truck drivers in the Kumasi metropolis, Ghana. Design/methodology/approach A cross-sectional study design enrolled 212 fuel tanker drivers. Sociodemographic, anthropometric, dietary and biochemical data were collected. MetS was assessed using the National Cholesterol Education Program Expert Panel on detection, evaluation and treatment of high blood cholesterol in adults Adult Treatment Panel III (NCEP ATP III) 2005 criteria. A three-day 24-h dietary recall was used to assess dietary intake. Binary logistic regression analysis was performed to determine the predicting factors of MetS among study participants. Findings The prevalence of MetS was 19.6% according to NCEP ATP III criteria. The prevalence of obesity, high BP, hyperglycaemia, dyslipidemia among participants were 7.5, 39.7, 37.7 and 57.3%, respectively. The energy intake for 176 (88.4%) of the participants was inadequate. The predicting factors of MetS were age (OR: 1.3, p = 0.04), glycated haemoglobin (OR: 9.6, p = 0.004), systolic blood pressure (OR: 1.2 95%, p = 0.01) and service years (OR: 0.8, p = 0.01). Research limitations/implications The current study focused on MetS among tanker truck drivers in Kumasi metropolis, which makes the current findings only limited to drivers of tanker truck within the municipality. Additionally, the 24-h dietary recall could be subjected to recall bias. However, the study is still of relevance as it becomes the first to target such a group within the municipality, taking into consideration the importance of these tanker truck drivers in driving the economy of Ghana. Originality/value This study highlights dietary intake and MetS among fuel tanker drivers previously underreported in the Ghanaian population. Findings of this study would inform further studies on lifestyle-related determinants of MetS among other cohort of drivers in other settings within the country.

Diabetes is a very common disease and is considered a risk factor for many diseases such as dry eye. The aim of the current work was to evaluate the tear evaporation rate (TER) in patients with diabetes using a hand-held evaporimeter. This observational, case–control and non-randomized study included 30 male patients with diabetes (17 controlled and 13 uncontrolled) with a mean ± standard deviation (SD) of 33.1 ± 7.9 years. An age-matched (18–43 years; 32.2 ± 6.5 years) control group consisting of 30 male subjects was also enrolled for comparison. Subjects with thyroid gland disorder, a high body mass index, high blood cholesterol, or thalassemia, contact lens wearers, and smokers were excluded. The TER was measured after the completion of the ocular surface disease index (OSDI) by each participant. The OSDI and TER median scores were significantly (Wilcoxon test, p < 0.05) higher in patients with diabetes (median (interquartile range; IQR) = 12.0 (8.3) and 46.4 (36.7) g/m2h, respectively) compared to the subjects within the control group (5.6 (7.0) and 15.1 (11.9) g/m2h, respectively). The median scores for the OSDI and TER measurements were significantly (Wilcoxon test, p < 0.05) higher among uncontrolled diabetes patients (13.0 (11.5) and 53.4 (14.2) g/m2h, respectively) compared to those obtained for patients with controlled diabetes (11.0 (8.0) and 27.3 (32.6) g/m2h, respectively). The tear evaporation rate in patients with diabetes was significantly higher compared to those obtained in subjects without diabetes. Uncontrolled diabetes patients have a higher tear evaporation rate compared to controlled diabetes patients. Therefore, diabetes can lead to eye dryness, since these patients possibly suffer excessive tear evaporation.

Phytosterols and phytostanols are a large group of compounds that are found exclusively in plants. They are structurally and functionally related to cholesterol but differ from cholesterol in the structure of the side chain. Phytosterols lower total and low-density lipoprotein (LDL) blood cholesterol by preventing cholesterol absorption from the intestine, so they have been known as blood cholesterol-lowering agents. Phytosterols are naturally found in fruits, vegetables, nuts, and mainly oils. Dietary phytosterol intakes normally range from 160-400 mg/day with variations depending on food culture and major food sources. Dairy foods remain a food of choice for use as delivery vehicle for many functional ingredients including phytosterols and there are many dairy products available in the global markets which are enriched with phytosterols. The use of phytosterols in commonly consumed dairy products may soon provide an effective tool against CVD and its introduction to our food products is worth anticipating in the near future as nutraceuticals for healthy ageing.

Heart failure contributes to a high number of hospitalizations. Currently, the number of outpatients is more dominant than hospitalized heart failure patients. Unfortunately, a study in the outpatient setting is still limited. This study aims to evaluate the correlation between lipid profile and kidney function in ambulatory heart failure patients. This study is a single-center cross-sectional study. Data were collected from August to September 2020. Data were extracted from 62 medical records of heart failure patients with ejection fraction 45%. Exclusion criteria were life-threatening comorbidity and patient with routine hemodialysis. Data were analyzed with Pearson or Spearman correlation test. Most of the heart failure patients in our outpatient clinic are elderly (60 years old) and male (58%). The researchers found positive correlation of total cholesterol (r 0.39; p 0.001) and triglyceride (r 0.59; p 0.001) to serum creatinine. On the other hand, LDL and blood cholesterol ratio negatively correlated with serum creatinine, r - 0.31; p 0.016; and r - 0.46; p 0.001; respectively. All of this analysis was statistically significant. It concluded that lipid profiles were correlated with kidney function in heart failure patients
