Background: Tea and coffee consumption is associated with cognitive function in some studies. Objective: We aimed to identify tea and coffee drinking patterns and their association with mean reaction time among Qatari adults. Method: The study included 1,000 adults aged 20 years and above attending the Qatar Biobank Study (QBB). Habitual tea and coffee consumption during the previous year was assessed by questionnaire. Tea and coffee drinking patterns were identified using factor analysis. In a computer-based self-administered touch screens test, mean reaction time (MRT) was used as an indicator of cognitive function. Results: The mean age of the participants was 35.8 (SD 10.3) years. Herbal tea and regular coffee consumption was inversely associated with MRT. In the multivariable model, compared with non-consumers, the regression coefficients for MRT were –34.3 (–65.4, –3.3) and –37.9 (–71.0, –4.7) for daily consumers of herbal tea and regular coffee, respectively. Of the two tea and coffee drinking patterns identified, pattern 1 (high consumption of tea, Arabic coffee, and herbal tea) was not associated with MRT but pattern 2 (high loadings of instant coffee, regular coffee, and Karak) was inversely associated with MRT in the unadjusted model. There was a significant interaction between pattern 2 and low-density lipoprotein (LDL) in relation to MRT. Pattern 2 was inversely associated with MRT among those with a low LDL. Conclusion: There was an inverse association between regular coffee and herbal tea consumption with mean reaction time. There was an interaction between Western coffee pattern and LDL.

The Relationship

Nowadays the general relevance of alcohol consumption in diabetes is extremely controversial. There are recent reports that alcohol consumption could result in a decreased incidence of diabetes, as well as other studies demonstrating a positive association between alcohol consumption and type 2 diabetes; there are also reports arguing for an inverse association between the two or for no correlation at all. The different results obtained in these studies could be explained by the existence of several confounders that could influence the outcome of the aforementioned studies. In this paper, we studied the possible relevance of BMI as a confounder in the relationship between alcohol consumption in diabetes and cognitive function, by analyzing the correlations between BMI values in diabetic patients with different alcohol drinking patterns and the subdomains from some main psychometric tests, such as MMSE (Mini-Mental State Examination) and MOCA (Montreal Cognitive Assessment). Our results provide evidence for BMI as a possible confounder of the relationship between alcohol consumption in diabetes and cognitive function. We found a significant increase (p<0.0001) in BMI values in patients with diabetes compared to our control group. Most importantly, significant correlations between BMI parameters in alcohol-consuming diabetic patients and most of the subdomains for psychometric testing.

IntroductionCholesterol levels have been associated with age-related cognitive decline, however, such an association has not been comprehensively explored in people with Parkinson’s disease (PD). To address this uncertainty, the current cross-sectional study examined the cholesterol profile and cognitive performance in a cohort of PD patients.MethodsCognitive function was evaluated using two validated assessments (ACE-R and SCOPA-COG) in 182 people with PD from the Australian Parkinson’s Disease Registry. Total cholesterol (TC), high-density lipoprotein (HDL), low-density lipoprotein (LDL), and Triglyceride (TRG) levels were examined within this cohort. The influence of individual lipid subfractions on domain-specific cognitive performance was investigated using covariate-adjusted generalised linear models.ResultsFemales with PD exhibited significantly higher lipid subfraction levels (TC, HDL, and LDL) when compared to male counterparts. While accounting for covariates, HDL levels were strongly associated with poorer performance across multiple cognitive domains in females but not males. Conversely, TC and LDL levels were not associated with cognitive status in people with PD.ConclusionHigher serum HDL associates with poorer cognitive function in females with PD and presents a sex-specific biomarker for cognitive impairment in PD.

Background: Cognitive impairments has become a global public concern. A limited number of studies suggest a positive association between nuts intake and cognitive function. Objectives: The aim of this study is to investigate the association between nuts consumption and cognitive function and to test whether hypertension and diabetes mediate this association among adults in Qatar. Methods: Data from 1000 participants aged 20 and above who attended Qatar Biobank (QBB) were used. Nuts consumption was assessed by a Food Frequency Questionnaire (FFQ). Blood samples were measured for magnesium and glucose. Cognitive function was assessed using computer self-administrated test to measure Mean Reaction Time (MRT). Linear regression was used to assess the association. Results: A total of 21.1% of the sample reported consuming nuts more than 4-6 times/week (high consumption) while 40.2% reported the consumption ≤1 time/month (low consumption). The mean MRT was 715.6 millisecond (SD 204.1). An inverse association was found between nuts consumption and MRT. Compared with those with a low consumption, high consumption of nuts had a regression coefficient of -36.95 (-68.09 to -5.82) after adjusting for sociodemographic and lifestyle factors. The inverse association between nuts and MRT was mainly seen among those aged >50 years. There was an interaction between nuts consumption and hypertension. The association between nuts consumption and MRT was not mediated via hypertension, diabetes, and serum magnesium. Conclusion: There is a positive association between nuts consumption and cognitive function, especially among old adults.

Background: Social status is associated with cardiovascular disease (CVD) prevalence and incidence. Aims: to investigate relationships between socioeconomic position (SEP) and common CVD biomarkers including adiponectin not previously investigated in a Swedish-population sample, and to assess if these associations changed with age. Design: Population-based longitudinal cohort study of men born 1920–24 with clinical measurements, blood samples, questionnaire data, and register-based information on SEP and cause of death. Methods: A total of 2322 men attended an investigation at age 50 of which 1221 attended a reinvestigation at age 70. Association between SEP and CVD biomarkers [cholesterol, low-density lipoprotein/high-density lipoprotein (LDL/HDL), apolipoprotein (Apo) ApoB/ApoA1, and adiponectin] were analysed by linear regression (adjusted for age, body mass index, and physical activity). SEP was measured as occupational class and educational level. CVD mortality over 36 years of follow-up was analysed by Cox regression. Results: At age 50, we found a significant inverse association of education with cholesterol level, LDL/HDL ratio and ApoB/ApoA1 ratio. Cholesterol was also associated with occupational class, statistically significant after adjustment for all covariates. At age 70, no significant associations were found between either measurement of SEP and any of the biomarkers studied. Highest educated men had decreased risk for CVD mortality during follow-up. Conclusions: Associations of SEP with cholesterol levels and LDL/HDL ratio that exist at age 50 are no longer apparent in the same group of men at age 70. We found no significant association between SEP and adiponectin levels at age 70.

The association between nuts intake and cognitive function is inconclusive. We aimed to investigate the association between habitual nuts consumption and cognition among Qatari adults. Data from 1000 participants aged >20 years who attended Qatar Biobank (QBB) were used. Nuts consumption was assessed by a food frequency questionnaire (FFQ). Blood samples were measured for magnesium, lipids and glucose. Mean reaction time (MRT) was used as an indicator of cognitive function. Linear regression was used to assess the association. A total of 21.1% of the participants reported consuming nuts ≥4–6 times/week (high consumption) while 40.2% reported consuming ≤1 time/month (low consumption). The mean MRT was 715.6 milliseconds (SD 204.1). An inverse association was found between nuts consumption and MRT. Compared to those with a low consumption, high consumption of nuts had a regression coefficient of −36.9 (95% CI −68.1 to −5.8) after adjusting for sociodemographic and lifestyle factors. The inverse association between nuts and MRT was mainly seen among those >50 years. There was an interaction between nuts consumption and hypertension. The association between nuts consumption and MRT was not mediated by hypertension, diabetes, or serum magnesium. Habitual higher consumption of nuts is positively associated with cognitive function, especially among old adults.

Background and Aims: Coffee consumption has been suggested to reduce the risk for hepatocellular carcinoma (HCC). While several studies report inverse correlation with coffee drinking, others have suggested more than 2 cups of coffee every day decrease the risk of liver cancer or HCC. However, controversy exists about the exact dose that would provide protective benefit. Therefore, we aimed to carry out a systematic review and meta-analysis of all studies that investigated the association of coffee consumption and risk of HCC and/or liver cancer. Our outcomes were the evaluation of the association of coffee with HCC or liver cancer development along with the amount of coffee needed to prevent HCC or liver cancer. Methods: We performed a PubMed/MEDLINE/EMBASE/Ovid/Google Scholar search of original articles published in English from 1996 to June 2019, on case-control or cohort or prospective studies that associated coffee with liver cancer or HCC. We calculated the relative risk (RR) of the two conditions for coffee drinking and then stratified this into increments of one cup of coffee per day. Twenty studies were identified. The analysis was performed using random effects models from the methods of DerSimonian and Laird with inverse variance weighting. The Cochrane Q and the I 2 statistics were calculated to assess heterogeneity between studies. A p<0.10 value for chi-square test and I 2 <20% were interpreted as low-level heterogeneity. Probability of publication bias was assessed using funnel plots and with the Egger’s test. Results: The overall RR was 0.69 (95%CI 0.56-0.85; p<0.001) with significant heterogeneity between the studies. We performed subgroup analysis over the increments of 1 cup of coffee. Higher doses of coffee consumption were associated with a significant decrease in the risks of developing HCC or liver cancer. The funnel plot did not show significant publication bias. Conclusions: Our systematic review and meta-analysis suggests that drinking coffee provides benefits with a reduction in the risk of HCC or liver cancer. Higher doses of coffee have higher benefits in terms of risk reduction. However, further biological and epidemiological studies are required to determine the exact mechanism and to study specific subgroups such as viral hepatitis B or C related HCC.

Abstract Background Dyslipidaemia and cognitive impairment are common in old adults and risks of both of them increase with increasing age. However, the relationship between lipids and cognitive impairment in longevous people is still unclear. This study aimed to assess the association between serum lipids and cognitive impairment in Chinese centenarians. Methods In a cross-sectional study, total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C) were biochemically measured in 924 centenarians and cognitive functions were evaluated. Multiple logistic regression analysis was used to examine the associations of lipids with cognitive impairment and the risks for cognitive impairment associated with quartile of serum lipid concentrations. Results The results demonstrated HDL-C was an independent beneficial factor for cognitive impairment after controlling for the potential covariates (Odds ratio, OR = 0.350, 95% Confidence interval, CI = 0.159–0.774; P = 0.009). An inverse association of HDL-C with cognitive impairment was found (P for trend = 0.001) and the association remained significant after adjusting for possible cofounders (P for trend = 0.012). The OR of cognitive impairment for the lowest versus highest quartiles of HDL-C was 1.96 (95%CI, 1.09–3.45). Conclusions The results indicated that low HDL-C is likely to be harmful for cognitive functions in centenarians. The cognitive function of longevous persons with low HDL-C concentrations deserves more attention.

ABSTRACTBackground:Research shows that lipid levels may be associated with cognitive function, particularly among women. We aimed to examine total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), triglycerides (TG), high-density lipoprotein (HDL), and HDL/LDL ratio in relation to cognitive performance, measured with six well-established cognitive domains and a composite cognitive score (CCS).Methods:In this cross-sectional study, biomarkers and neuropsychological assessment were available for 141 adults with MMSE scores ≥ 24 (mean age = 69 years, 47% female, mean education = 14.4 years) attending a neuropsychological evaluation. Ordinary least squares regressions were adjusted for age, gender, education, and depressive symptoms in Model 1 and also for apolipoprotein E4 (APOE4) status in Model 2.Results:High-density lipoprotein cholesterol (HDL-C) was associated with better CCS (β = 0.24; p = 0.014). This association was significant among women (β = 0.30; p = 0.026) and not among men (β = 0.20; p = 0.124). HDL-C was also related to attention/working memory (β = 0.24; p = 0.021), again only among women (β = 0.37; p = 0.012) and not men (β = 0.15; p = 0.271). Adjusting for APOE4 yielded significance for high HDL-C and CCS (β = 0.24; p = 0.022).Conclusions:HDL-C was the main lipoprotein affecting cognitive function, with results somewhat more pronounced among women. Research should investigate the possibility of finding ways to boost HDL-C levels to potentially promote cognitive function.

AbstractEpidemiologic studies have indicated that dyslipidemia may facilitate the progression of cognitive dysfunction. We previously showed that patients with metabolic syndrome (MetS) had significantly higher plasma levels of electronegative very-low-density lipoprotein (VLDL) than did healthy controls. However, the effects of electronegative-VLDL on the brain and cognitive function remain unclear. In this study, VLDL isolated from healthy volunteers (nVLDL) or patients with MetS (metVLDL) was administered to mice by means of tail vein injection. Cognitive function was assessed by using the Y maze test, and plasma and brain tissues were analyzed. We found that mice injected with metVLDL but not nVLDL exhibited significant hippocampus CA3 neuronal cell loss and cognitive dysfunction. In mice injected with nVLDL, we observed mild glial cell activation in the medial prefrontal cortex (mPFC) and hippocampus CA3. However, in mice injected with metVLDL, plasma and brain TNF-α and Aβ-42 levels and glial cell activation in the mPFC and whole hippocampus were higher than those in control mice. In conclusion, long-term exposure to metVLDL induced levels of TNF-α, Aβ-42, and glial cells in the brain, contributing to the progression of cognitive dysfunction. Our findings suggest that electronegative-VLDL levels may represent a new therapeutic target for cognitive dysfunction.

BACKGROUND Although patients are instructed to abstain from food before having blood drawn for lipid analysis, many still drink coffee in the morning. It is unknown whether coffee consumed prior to drawing blood samples will impact fasting serum lipids. OBJECTIVE To determine whether a single 6-oz cup of coffee with or without the addition of nondairy creamer and sugar will significantly affect fasting plasma lipid profiles. METHODS This was a prospective, open-label, randomized crossover study. At the first of 2 visits, blood was drawn to measure initial fasting lipid panels, and participants were randomized to drink 6 oz of black coffee or coffee with nondairy creamer and sugar. Within 30–60 minutes of coffee consumption, blood was drawn for follow-up lipid panels. The procedure was repeated at the second visit, except the participants were crossed over to receive the alternate coffee preparation. RESULTS Forty participants (26 men; age [mean ± SD] 45 ± 15 y) were enrolled. Total cholesterol (TC) increased from 188.2 ± 38.1 to 191.3 ± 39.9 mg/dL (p = 0.019) and high-density lipoprotein cholesterol (HDL-C) increased from 43.2 ± 12.3 to 44.8 ± 12.9 mg/dL (p < 0.001) after consumption of black coffee. Triglycerides decreased from 145.6 ± 123.7 to 136.3 ± 107.1 mg/dL (p = 0.014) after consumption of coffee with nondairy creamer and sugar. Changes in other lipid parameters, such as low-density lipoprotein cholesterol in either group, were not statistically significant. CONCLUSIONS A single cup of coffee consumed within one hour before drawing blood resulted in statistically, but not clinically, significant differences in TC and HDL-C (black coffee) and triglycerides (coffee with creamer and sugar).
