Background: Green tea, obtained from the plant Camellis sinensis, is one of the oldest drinks in the world and contains numerous bioactive compounds. Studies have demonstrated the efficacy of green tea in preventing obesity and cardiovascular diseases that may be related to the reduction of lipid levels. Aim: This study aimed to evidence, through a systematic review, the therapeutic potential of green tea on the lipid profile in preclinical studies in obese animals and clinical studies in obese individuals. Methods: This systematic review follows the recommendations of the preferred report items for systematic reviews and meta-analyses. The electronic databases, PubMed (Medline), Science Direct, Scopus, and Web of Science were consulted. Articles from January 2009 to December 2019 were selected. Results: This search resulted in twenty-nine articles were included cirtically reviewed. In experimental studies, green tea administration has been shown to reduce total cholesterol, triglycerides and low-density lipoprotein cholesterol in animals exposed to obesity-inducing diet. In humans’ studies green tea was not shown to be effective for obese lipid control. Because supplementation with green tea extract reduced total cholesterol, triglycerides, low-density lipoprotein for three months at a specific dose. Conclusion: Therefore, green tea appears to act as a protective agent for dyslipidemia in obesity-induced animals. In human studies, green tea has not been shown to be effective in controlling obese lipids.

Objectives: Low cholesterol has been linked with violent and suicidal behaviour in people with schizophrenia. This association, if consistently present, may be a promising biological marker that could assist clinicians in decision making regarding risk and treatment. We conducted a systematic review to assess whether there is a reliable association between lipid profile (total cholesterol, high- and low-density lipoprotein cholesterol, and triglycerides) and aggression, self-harm or suicide in people with schizophrenia, and whether effects are similar in males and females. Method: Relevant databases were searched to identify primary research studies (up to November 2020) that (1) involved adults (some samples also included 16- to 18-year olds) with a confirmed diagnosis of schizophrenia, schizoaffective disorder or psychosis; and (2) included a standardised assessment of verbal aggression, physical aggression against objects, physical aggression against self (including suicide) or others. The search yielded 23 studies eligible for inclusion following a quality appraisal. Results: Suicidality was the most commonly assessed subtype of aggression (20 studies). For suicidality, about half the studies, including the study with the largest sample size, found a link with total cholesterol. An association between low total cholesterol and violence towards others was found in six of nine studies that investigated this. The evidence for a link with violence was the strongest for total cholesterol, followed by low-density lipoprotein cholesterol and high-density lipoprotein cholesterol, and the weakest for triglycerides. Only a few studies investigated sex differences and yielded mixed evidence. Studies focussed on self-harm as well as involving females in forensic settings were lacking. Conclusion: There is encouraging evidence of an association between low total cholesterol and aggression towards others as well as suicidality in schizophrenia. Future studies should systematically explore this association in people with schizophrenia who have a significant history of violence, suicidality and self-harm, both inpatients and community, and also investigate underlying mechanisms.

Background. Changes in lipid profile are commonly reported in adult patients with malaria. However, a few studies evaluated lipid abnormalities in children continuously exposed toP. vivax.Objective. To evaluate lipid abnormalities in children withP. vivaxinfection and to assess if parasite count or the history of malaria correlates with lipid levels at admission.Methods. A total of 75 children were included in the study, from which 43 were slide confirmed infection byP. vivax. Serial blood samples were collected at admission and, on days 7 and 14, evaluated for the colorimetric measurements of triglycerides, very low-density lipoprotein (VLDL), total cholesterol, high-density lipoprotein (HDL), and low-density lipoprotein (LDL).Results. The levels of total cholesterol, LDL, and HDL were significantly lower in malaria cases. The levels of VLDL and triglycerides were significantly higher in children with malaria. Such changes were transient and were not associated with parasite counting as well as with the history of malaria of patients.Conclusion. There are significant lipid abnormalities in children with low level ofP. vivaxinfection and mild signs and symptoms of the disease, which are not associated with parasitaemia and previous episodes of disease.

Tea Benalu (Scurrula atropurpurea [Bl.] Dans.) and Mango Benalu (Dendrophthoe pentandra L. miq.) containssecondary metabolites with potential antioxidant potential. Antioxidants can inhibit the oxidation process and reduce Total Cholesterol, Triglycerides, Low-Density Lipoprotein (LDL) and increase High-Density Lipoprotein (HDL). The safety of the preparations for the combination of parasites of tea and mango leaves was tested to obtain toxic effects after repeated treatment tests over some time. The purpose of this study was to determine the toxic effects of a combination of methanolic extracts of a combination of tea parasites and mangoes in female rats (Rattus norvegicus) subchronically for 28 days by looking at the results of the clinical biochemical examination on lipid profiles, namely total cholesterol levels, triglycerides, high-density lipoproteins (28%). HDL), and Low-Density Lipoprotein (LDL). The method of this study was experimental with a combination dose of methanol extract of tea parasite leaves and mango parasite leaves at a dose of 250 mg / KgBB, 500 mg / KgBB and 1000 mg / KgBB with 5x replications each treatment. The subjects used white rats (Rattus norvegicus) female Wistar strains aged 6-8 weeks with a minimum body weight of 100 grams. The treatment in this study was in the form of each dose given 5 times a week for 28 days (subchronic toxicity test) orally. Lipid profile levels were analyzed using the one-way ANOVA test. The results showed that the level of control blood lipid profile with a treatment dose of 250 mg / KgBW, 500 mg / KgBW, and 1000 mg / KgBW was not significantly different. The toxicity test of combined extracts of tea leaves and mango parasite leaves of female rat Rattus novergicus on subchronic exposure 28 days with those doses showed no difference tangible between treatments of controls. This means it is safe and does not cause toxic properties in the lipid profile of female wistar rats.Keywords: Lipid Profile, Scurrula atropurpurea, Dendophthoe pentandra, Sub-Chronic Toxicity, Rattus norvegicus ABSTRAKBenalu Teh (Scurrula atropurpurea [Bl.] Dans.) dan  Benalu Mangga (Dendrophthoe pentandra L. miq.) mengandung metabolit sekunder berpotensi sebagai antioksidan.

Overweight and obesity in youth is a worldwide public health problem. Predisposition to obesity starts during the first or second decade of life. Overweight and obesity in adolescents have a substantial effect upon many systems, resulting in clinical conditions such as metabolic syndrome, early atherosclerosis, dyslipidaemia, hypertension and type 2 diabetes mellitus. Our study was done to find the relation between body mass index (BMI) and lipid profile in young adults (18-20 years) and for the correlation between the various parameters. 150 young adults between 18-20 years of age, who gave written voluntary consent were included in the study. BMI was calculated after measuring height and weight along with fasting blood samples for estimation of blood glucose and lipid profile [Total cholesterol, High density lipoprotein (HDL), Low density lipoprotein (LDL), Very low density lipoprotein (VLDL) and triacylglycerol (TGL)] were measured. The data collected was analysed using Statistical package for the social sciences (SPSS) statistics software version 20. A linear correlation regression analysis was done to know the correlation between the anthropometric measurements and biochemical parameters. ANOVA test was performed to know the significance and a p value of < 0.01 was taken as significant. All the biochemical parameters showed a positive correlation with BMI. Total cholesterol had the highest positive correlation with BMI. There was a prevalence of 39.3% overweight/obesity as per BMI cut-off. Individuals who were in the obese category had a higher prevalence of abnormal lipid profile especially total cholesterol. Stress and lack of physical activity have a detrimental effect on health and are a major risk factor for development of obesity. 90% of the students in this study did not have any regular physical activity. Educating the students about effects of obesity and dyslipidaemia on quality of health can help in bringing life style modifications which can help them in the long run.

Menopausal Women

Lipid profile comparative analysis was performed to reveal the interdependence of lipids with Circadian locomoter output cycles protein kaput (CLOCK) 3111T/C gene polymorphism in menopausal women with/without a body mass index (BMI) of ≥25 kg/m2. Methods: A total of 193 female volunteers aged 45 to 60 years were divided into two groups: Those with BMI < 25 kg/m2 (control) and those with BMI ≥ 25 kg/m2. Each group was then divided into two subgroups: Those with the CLOCK TT-genotype and those with the CLOCK TC-, CC-genotypes. Lipid metabolism parameters were determined by the enzymatic method. Single-nucleotide polymorphisms (SNPs) were detected via polymerase chain reaction–restriction fragment length polymorphism technology. Results: There were no differences in CLOCK 3111T/C genotypes or allele frequency between the control and main groups. In addition, there were no differences in lipid profile parameters between women of the control group and different CLOCK 3111T/C genotypes. The total cholesterol (p = 0.041) and low-density lipoprotein cholesterol (p = 0.036) levels were higher in the subgroup of women with a BMI ≥ 25 kg/m2 and CLOCK TT-genotype as compared to the subgroup with a BMI ≥ 25 kg/m2 and minor allele 3111C. Conclusions: SNP 3111T/C of the CLOCK gene is not associated with BMI however, data suggest that the minor allele of the CLOCK 3111T/C gene polymorphism may have a protective role in atherogenic lipid levels in women with a BMI greater than or equal to 25 kg/m2.

Hypertensive Patients

Back ground: Hypertension and dyslipidemia are associated with oxidative stress and are major causes of cardiovascular disease amounting to 30% of global death rate. It is widely accepted that cardiovascular disease is associated with hypertension and increased blood levels of low-density lipoprotein (LDL), total cholesterol (TC), and triglycerides. In contrast, a low level of high density lipoprotein (HDL) is a risk factor for mortality from cardiovascular disease. Hypertension is a major public health problem in developed and developing countries. Methods: This study was a cross sectional study in which 159 diagnosed hypertensive patient and 75 with normal blood pressure (normotensive) were enrolled. These patients sought a through health cheek up including blood pressure assessment between May 2012 to April 2013 in Tairunnessa Memorial Medical College and Hospital. Lipid parameter total cholesterol (TC), triglyceride (TG), low density lipoprotein ( LDLc) and high density lipoprotein (HDLc) were estimated by enzymatic colorimetric test. Results: The mean of Systolic blood pressure and Diastolic blood pressure of hypertensive were higher than normotensive (p<0.001). The serum levels of total cholesterol, triglyceride and LDL-C in hypertensive subject were higher than normotensive and statistically significant (p<0.001). Serum HDL-C was significantly lower (p<0.001) in hypertensive patients than in normotensive. Conclusion: Analytical results of the study revealed that hypertensive patients have been found to have close association with dyslipidemia. Hypertension and dyslipidemia can be modified either by proper life style changes or medical management or by the combination of the both. This study suggests that hypertensive patients need measurement of blood pressure and lipid profile at regular interval to prevent heart diseases and stroke.

Ramadan Fasting

The study was conducted to evaluate the effects of fasting for a period of one month during Ramadan on the lipid profile of Bangladeshi female volunteers who fasted during the Arabic month of Ramadan, when there occurs a change, both in the pattern and timing of dietary intake. Findings of the study showed that Ramadan fast significantly reduced serum Total cholesterol (TC) (p=0.030) and Low density lipoprotein (LDL-C) (p=0.011). A statistically nonsignificant elevation of triglyceride (TG)) was observed (p=0.598). High density lipoprotein cholesterol (HDL-C) also found to be raised significantly at the end of fasting (p = 0.037). Findings of the study revealed that fasting during the month of Ramadan changes lipid profile pattern in an aniatherogenic direction and may be beneficial to health.
