Importance: Sleep duration has been considered as a risk factor for cardiometabolic disease and mortality. Several studies suggest that sleep duration can influence the serum lipid levels, but the association remains unclear. Objective: The aim of present study is to assess the association of sleep duration with serum lipid levels in an elderly Korean population. Methods: The KURE study is a cohort study to investigate risk factors for major disorders of the elderly. This cross-sectional analysis was conducted among 926 participants (302 men and 624 women aged 64-87 years) who completed baseline health examination in 2012. Sleep duration was measured by the interviewer-assisted questionnaire. Habitual sleep time was calculated based on the response to the questions about hour of bedtime, hour of rising, and hours of nap during the passing year. Total cholesterol, triglyceride and high density lipoprotein (HDL) cholesterol concentrations in serum were measured from overnight fasting blood samples. Low density lipoprotein (LDL) cholesterol was calculated from total cholesterol, HDL cholesterol and triglyceride levels using Friedewald’s formula. Multiple linear regression models were conducted to examine whether sleep duration was associated with serum lipid levels. Results: Sleep duration was not significantly associated with total cholesterol (β=-0.154mg/dL per sleep hour, p =0.843), triglyceride (β=-1.000, p =0.506) and LDL cholesterol (β=0.678, p =0.339) after adjusting for age, sex, body mass index, systolic blood pressure, tobacco smoking, alcohol intake, physical activity, diabetes mellitus, myocardial infarction and stroke. However sleep duration was inversely associated with HDL cholesterol (β=-0.644, p =0.015) in fully adjusted model. In the sex-specific analysis, sleep duration was marginally associated with HDL cholesterol in men (β=-0.770, p =0.078) and significantly associated with HDL cholesterol in women (β=-0.685, p =0.037) after fully adjustment. Conclusions: Our findings suggest that longer sleep duration was associated with lower serum HDL cholesterol level in an elderly Korean population.

Abstract This study evaluated the effect of the temperament of 75 water buffaloes of three genetic groups (GG: Jafarabadi, Mediterranean, and Murrah; n = 25 for each GG) on serum lipid levels. The animals were classified for temperament through the temperament score (TSc) obtained by the mean of the sum of the scores of the entry time into the squeeze chute (1 to 5: 1=greater time spent for entry, and 5=less time spent for entry) and the exit velocity score (1 to 5: 1=lower speed, and 5=higher speed) calculated after the period of adaptation to the feedlot (d0). The animals were categorized into adequate (ADQ; TSc≤3) or excitable (EXC; TSc >3) temperaments. Blood samples were collected from the jugular vein on days -28, 0, and 84, and evaluated for serum levels of total cholesterol, triglycerides, high-density lipoprotein (HDL), low-density lipoprotein (LDL), and very low-density lipoprotein (VLDL) using colorimetric enzymatic analyses performed by commercial kits. Data were analyzed using MIXED procedure in SAS, considering the GG, temperament, day, and the resulting interactions as fixed effects. The term day was used for repeated measures in time. Correlations were estimated using the CORR procedure in SAS. There were no interactions for the variables evaluated (P ≥ 0.11). ADQ animals showed lower levels of total cholesterol (65.95 vs 70.96mg/dL for ADQ and EXC, respectively; SEM=2.33; P = 0.04) and LDL (26.74 vs 30.40mg/dL for ADQ and EXC, respectively; SEM=1.57; P = 0.02) than EXC animals. There was no effect of temperament for the triglycerides (P = 0.41), HDL (P = 0.47), and VLDL (P = 0.46). Positive correlations were verified between both the TSc and triglycerides (r=0.32; P < 0.01), and TSc and VLDL (r=0.33; P < 0.01). Tendency for a positive correlation was detected between TSc and LDL (r=0.20; P = 0.09). In conclusion, there are differences in serum lipid levels between water buffalo temperaments which deserves further investigation. Supported by FAPESP (#2018/25939-1; #2014/05473-7).

Abstract Background/Aims: While observational studies show an association between serum lipid levels and cardiovascular disease (CVD), intervention studies that examine the preventive effects of serum lipid levels on the development of CKD are lacking. Methods: To estimate the role of serum lipid levels in the etiology of CKD, we conducted a two-sample Mendelian randomization (MR) study on serum lipid levels. Single nucleotide polymorphisms (SNPs), which were significantly associated genome-wide with plasma serum lipid levels from the GLGC and CKDGen consortium genome-wide association study (GWAS), including total cholesterol (TC, n = 187365), triglyceride (TG, n = 177861), HDL cholesterol (HDL-C, n = 187167), LDL cholesterol (LDL-C, n = 173082), apolipoprotein A1 (ApoA1, n = 20687), apolipoprotein B (ApoB, n = 20690) and CKD (n = 117165), were used as instrumental variables. None of the lipid-related SNPs was associated with CKD (all P > 0.05). Results: MR analysis genetically predicted the causal effect between TC/HDL-C and CKD. The odds ratio (OR) and 95% confidence interval (CI) of TC within CKD was 0.756 (0.579 to 0.933) (P = 0.002), and HDL-C was 0.85 (0.687 to 1.012) (P = 0.049). No causal effects between TG, LDL-C- ApoA1, ApoB and CKD were observed. Sensitivity analyses confirmed that TC and HDL-C were significantly associated with CKD. Conclusions: The findings from this MR study indicate causal effects between TC, HDL-C and CKD. Decreased TC and elevated HDL-C may reduce the incidence of CKD but need to be further confirmed by using a genetic and environmental approach.

Introduction: Dengue Virus (DENV) infection now remains as the most rapidly spreading viral disease worldwide. Lower lipid level occurs in critically ill patients with DENV infection and is postulated as an independent predictor of the clinical outcome. Aim: To find the correlation between serum lipid levels and severity in children admitted with various grades of Dengue Haemorrhagic Fever (DHF) and secondarily to correlate serum lipid levels with factors like platelet count and duration of hospital stay. Materials and Methods: This was a prospective descriptive study done in the Paediatric ward from October 2019 to December 2019. Febrile Children with a platelet count of less than 1 lakh/cu.mm and positive for DENV IgM antibodies by Enzyme Linked Immuno Sorbent Assay (ELISA) formed the study group. Demographic details, number of days of fever on admission, duration of stay in hospital and severity grading of DENV infection as per the National guidelines were collected. These children were evaluated with Complete Blood Counts (CBC), fasting lipid profile, X-ray chest and ultrasound abdomen. Mean and standard deviation was used for categorical variables. Chi-square test was used to assess the strength of association between lipids and severity of DENV infections. Pearson correlation coefficient was used to assess R value between length of stay and serum lipid levels. Results: The Total Cholesterol, Low Density Lipoprotein (LDL), Triglyceride and Very Low Density Lipoprotein (VLDL) showed a simple linear decline as the severity grade advanced from grade I to grade IV. However, statistical significance was found only for total cholesterol and LDL with p-values of 0.046 and 0.041 respectively. The distribution of High Density Lipoprotein (HDL) across the grades of severity did not follow any pattern and was randomly distributed. On analysis of Pearson correlation between number of days of hospital stay and lipid profile, statistical significance was observed for LDL alone (p=0.023). Conclusion: The serum levels of total cholesterol and LDL were significantly reduced in severe grades of DHF. Serum levels of total cholesterol and LDL can be used as an economical surrogate marker to predict the severity of DHF at the time of admission.

A prospective study was conducted in the Northern region of Bangladesh, to investigate the serum lipid profile viz the level of total cholesterol (TC), Triglyceride (TG), HDL-cholesterol and LDL-cholesterol of hypertensive patients and compares them with levels of control subjects. The results revealed that serum total cholesterol, triglyceride and LDL-cholesterol were significantly markedly raised (p>0.001) whereas the level of HDL-cholesterol was significantly lower (p>0.001) in hypertensive patients as compared to control subjects. No significant changes of serum lipid profile were found between male and female hypertensive patients, but in control subjects, markedly higher levels of serum lipid profile was observed in male compared to that of female. It was concluded that hypercholesterolaemia, hypertrigyceridaemia and low density lipoprotein are the main lipid abnormalities on the incidence of hypertension in the study area.

IntroductionEvidence for a possible association between a low level of cholesterol and increased suicidal behaviour has accumulated in the recent 3 decades. The present study investigates whether lipid levels can make state-dependent markers of suicidal behaviour in Polish patients with mood disorder recently admitted to a psychiatric hospital owing to an acute depressive episode.Materials and methodsThe study was conducted on 223 patients (73 male and 150 female) with unipolar (n=171) and bipolar (n=52) depression. They were interviewed to assess any occurrence of suicidal thoughts, suicidal tendencies and/or suicidal attempts during the 3 months before admission. Laboratory measurements [total cholesterol, low density lipoprotein (LDL) cholesterol, high density lipoprotein (HDL) cholesterol, triglycerides and total lipids] were obtained within 24–72 h after hospital admission.ResultsSuicidal thoughts, tendencies, and attempts were associated with low total cholesterol, LDL cholesterol, and total lipids in both male and female patients, in both diagnostic categories. Triglycerides were significantly lower in male and female patients with suicidal thoughts compared with their non-suicidal counterparts. No association with suicidality was found with HDL cholesterol.ConclusionsThe results of our study support a majority of research showing the association in depressed patients between suicidal behaviour and low levels of total and LDL cholesterol. In addition, the data suggest a similar association with low total lipids, and in some instances, with low triglycerides.

Abstract Context Vitamin D deficiency is highly prevalent across the world. The existing evidence suggests vitamin D may have beneficial effects on serum lipid profiles and thus cardiovascular health. Objective The objective of this systematic review and meta-analysis was to examine the effect of vitamin D supplementation on serum lipid profiles. Data Source Original randomized controlled trials (RCTs) examining the effect of vitamin D supplementation on serum lipid profiles and published before July 2018 were identified by searching online databases, including PubMed, Google Scholar, and ScienceDirect, using a combination of relevant keywords. Data Extraction Data on study characteristics, effect size, measure of variation, type of vitamin D supplementation, and duration of follow-up were extracted by the author. Data Analysis PRISMA guidelines for systematic reviews were followed. Random effects (DerSimonian and Laird [D-V)] models were used to pool standardized mean differences in total cholesterol, low-density lipoprotein (LDL) cholesterol, high-density lipoprotein (HDL) cholesterol, and triglycerides between the active and the placebo arms of RCT studies. Between-study heterogeneities were assessed using Cochrane Q and I2, and publication bias was assessed using Begg’s test, Egger’s test, and funnel plot. Results A total of 41 RCTs comprising 3434 participants (n = 1699 in the vitamin D supplementation arm and n = 1735 in the placebo arm) were identified and included in the meta-analysis. Approximately 63.4% of study participants were women, with 14 studies conducted entirely among women. Approximately 24% of the trials had follow-up duration >6 months, whereas the remaining 76% had follow-up duration of <6 months. The standardized mean differences (SMDs) and 95% confidence intervals (CIs) for comparing the change from baseline to follow-up between the vitamin D supplementation arm and the placebo (control) arm were as follows: total cholesterol = –0.17 (–0.28 to –0.06); LDL cholesterol = –0.12 (–0.23 to –0.01); triglycerides = –0.12 (–0.25 to 0.01); and HDL cholesterol = –0.19 (–0.44 to 0.06). After removing a trial that was an outlier based on the magnitude of the effect size, the SMD for triglycerides was –0.15 (–0.24 to –0.06) and that for HDL cholesterol was –0.10 (–0.28 to 0.09). The improvements in total cholesterol and triglycerides were more pronounced in participants with baseline vitamin D deficiency. Conclusions Vitamin D supplementation appeared to have a beneficial effect on reducing serum total cholesterol, LDL cholesterol, and triglyceride levels but not HDL cholesterol levels. Vitamin D supplementation may be useful in hypercholesterolemia patients with vitamin D insufficiency who are at high risk of cardiovascular diseases.

Previous studies have found that serum lipid levels independently associate with mental health problems in adulthood. However, little is known about the association between serum lipid levels and positive aspects of mental health such as resilience and self-esteem, which develop in adolescence. The aim of this study is to examine the association between serum lipid levels and resilience and self-esteem in Japanese adolescents. Data were pooled data from the Adachi Child Health Impact of Living Difficulty (A-CHILD) study in 2016 and 2018, a school-based, cross-sectional study in Adachi City, Tokyo, Japan (N = 1,056, aged 13–14 years). Resilience of the child was assessed by caregivers, and self-esteem was self-identified via questionnaires. Serum lipid levels [total cholesterol, low-density lipoproteins (LDL), and high-density lipoproteins (HDL)] were assessed in school health checkup, in addition to height and weight measurements. Multiple linear regression was applied to investigate the association between standardized serum lipid levels and resilience and self-esteem. LDL showed inverse association with resilience [β = −1.26, 95% confidence interval (CI) = −2.39 to −0.14] after adjusting for child’s BMI, month of birth, sex, absence of parent, household income, caregiver’s mental health, and lifestyle (e.g., habits of eating, physical activity, and sleep). We also found an inverse association of total cholesterol and higher LDL cholesterol with self-esteem (β = −0.58, 95% CI = −0.99 to −0.18; β = −0.42, 95% CI = −0.83 to −0.01, respectively). HDL cholesterol was not associated with resilience and self-esteem. Among Japanese adolescent, total and LDL cholesterol may be biomarkers of resilience and self-esteem.

Background: Migraine is associated with increased prevalence of cardiovascular risk factors and vascular biomarkers and migraine with aura is associated with increased risk of ischemic stroke. Lipid abnormality is a risk factor for both cardiovascular and cerebrovascular disease. The vast majority of previous studies evaluated the association between lipid levels and migraine among young and middle aged persons abroad. So far we know, no study has been conducted in Bangladesh regarding association of lipid levels with migraine. Objectives: The present study is aimed to evaluate the association between serum lipid levels in patients with migraine. Materials and Methods: This observational, cross-sectional study was carried out on 100 patients in outpatient departments of Enam Medical College and Hospital, Dhaka and Mymensingh Medical College Hospital, Mymensingh over a period of one year (December 2017 to November 2018). Patients were selected by purposive sampling. Fifty migraine and 50 non-migraine patients were recruited in the study. Results: The serum total cholesterol and LDL-C were significantly higher in migraine than in non-migraine group. HDL-C was below normal and triglyceride was within normal range in both groups. Serum total cholesterol and LDL-C were significantly higher in migraine with aura than migraine without aura. HDL-C level was lower in migraine without aura and was of normal level in migraine with aura, which was statistically significant. Conclusion: Elevated levels of serum total cholesterol and LDL cholesterol were associated with migraine than non-migraine group. Serum total cholesterol and LDL cholesterol were significantly higher in late age of migraine group and migraine with aura. J Enam Med Col 2020; 10(1): 27-32
