Metabolic syndrome in patients with severe mental illness in Gorgan

The establishment of rat model in myocardial ischemia with psychological stress

Background

Psychological stress can provoke and aggravate myocardial ischemia, and this stress can even trigger acute coronary syndromes or sudden cardiac death. Therefore, for the first time, this study aimed to investigate the method for establishing a rat model of myocardial ischemia with psychological stress and its evaluation.

Methods

Forty male Wistar rats were randomly divided into the sham (S, n=10), myocardial infarct (MI, n=10), psychological stress (MODEL, n=10), and myocardial infarct with psychological stress (MI + MODEL, n=10) groups. The rat model of psychological stress was established by measuring the data from activity restriction for 6 hours and followed by tail clamp stimulation for 5 minutes every day for 14 days. The rat model of the myocardial infarct with psychological stress was established by occluding the left coronary anterior descending artery in the MODEL rats. The body weight of rats was measured daily, the behavior parameters were evaluated via open-field test and elevated plus-maze, tongue color and sublingual vein were observed, rats' acral blood flow perfusion was detected by PIM II (Perfusion Imager II), mesenteric microcirculation was measured by capillaroscopy, and hemodynamics was measured by a polygraph system. An automatic biochemical analyzer determined the content of serum cTnT (cardiac troponin T), Hcy (homocysteine), and activity of LDH (lactate dehydrogenase). Myocardial infarct size was measured with TTC (triphenyhetrazolium chloride) staining.

Results

We found that rats in the psychological stress (MODEL) group were characterized by coarse hair, dark mucosa of the lips and claw, low spirit, decreased body weight, and increased anxiety. Compared with rats in the sham group, rats in the MODEL + MI group showed decreased mesenteric blood flow, narrowed arteriole and venule diameter, reduced acral blood flow perfusion, and LV ±dp/dt_max (the maximal rate of the increased and decrease of left ventricular pressure), as well as increased serum content of cTnT, Hcy, and LDH activity. Compared with the MI group, rats in the MODEL + MI group showed deteriorated microcirculation dysfunction manifested as a dark tongue color of deep purple, prominently extended and varicose sublingual vein, and aggravated myocardial damage in the form of increased infarct size and LDH leakage.

Conclusions

In conclusion, the rat model of myocardial ischemia with psychological stress was successfully established, and manifested as aggravating behavioral disorder, mesenteric microcirculation and left ventricular dysfunction, and myocardial damage.

A Retrospective Chart Review of Screening on the Prevalence of Metabolic Syndrome (MetS) in an Irish Community Mental Health Service

Individuals who are treated with antipsychotic medications are at risk of developing metabolic syndrome (MetS). The comorbidity of a severe mental illness (SMI) and a physical illness has a major impact on the quality of life of these individuals. We conducted a retrospective chart review (RCR) of 214 individuals with a diagnosis of schizophrenia who had been receiving antipsychotic medications for at least 6 months, in five clinical settings in an Irish community mental health service. The aim was to determine the presence of MetS to assist in improving screening practices and directing future practice. The National Cholesterol Education Program High Blood Cholesterol Adult Treatment Panel 111 (NCEP ATP 111) metabolic diagnostic criteria were utilised to determine prevalence. After examining 214 charts we observed that waist circumference varied from 68 to 142 cm, elevated waist circumference over the recommended parameters was recorded in 145 charts. Forty-five percent (n = 98) had blood pressure (BP) readings over 130/85. The range for body mass index (BMI)'s varied from 16 to 54, BMIs over 25 was recorded in 44% (n = 95) of charts. Elevated triglycerides (TG) were recorded in 37% (n = 80) and 45% (n = 97) had reduced HDL-C levels. Elevated glucose levels were found in 25% (n = 54) of the charts examined. The chart review found an overall prevalence rate of 44% (n = 94) for this sample. Regular audit of screening data used for the presence of MetS in individuals with SMI is essential in the detection of physical comorbidities and to improving the quality of life and prevention of premature deaths.

Prevalence of Metabolic Syndrome in the Hospitalized Psychiatric Patients

Introduction

Metabolic Syndrome (MetS) is one of the most common syndromes that include a set of serious cardiovascular risk factors. MetS is highly prevalent in the high risk population and contributes to reduced lifespan. The primary goal of the study is to assess the prevalence of MetS and its relation to the treatment modalities and the psychiatric diagnosis.

Methods

A cross-sectional study for the hospitalized patients in the Mental Health hospital in Taif city, Saudi Arabia that was conducted between Dec 2013 - Nov 2015. We included adult patients who were admitted to the inpatient service. We diagnosed MetS according to the new International Diabetes Federation (IDF) definition.

Results

A total of 313 patients with mean age 48.4+10.8 years old, the majority were male and single, 68.3% have high school degree or less, mean BMI in the overweight range, and mean waist circumference 96.5+14.0 cm. Compared to these without MetS, those with MetS more likely to have BMI and waist circumference (P <0.001), higher SBP (P 0.028), have diabetes, hypertension and hyperlipidemia (all P <0.001), longer inpatient hospitalization (P 0.0036), report sedentary lifestyle (P 0.733), consume soft drink on a daily basis (P 0.030), and were active smoker (P 0.002). Those with MetS were less likely to be on Haloperidol and valproic acid (P 0.026).

Conclusion

39% of the participated hospitalized patients met the criteria for MetS and they tends to have significantly higher adiposity measures, cardiovascular markers, more likely to have comorbid conditions, and be active smokers.

Metabolic syndrome in drug naïve schizophrenic patients

INTRODUCTION

Research in the last decade tried to focus on natural and unnatural causes of death in schizophrenic patients, but recent few years has focussed on emerging cardio-metabolic risk factors, as a cause of mortality in such patients.

AIM OF THE STUDY

To assess the determinant of metabolic syndrome in drug naïve schizophrenic patients.

METHODOLOGY

It was a cross sectional study; 30 indoor patients with diagnosis of schizophrenia were included. Height, weight, waist circumference and Blood pressure assessment was done by using standard protocol. Fasting Blood Glucose (FBG), Triglyceride (TGs), High Density Lipoprotein (HDL) cholesterol, Low Density Lipoprotein (LDL) total cholesterol were measured. International Diabetes Federation (IDF) criteria was considered for establishing metabolic syndrome. Statistical analysis was done by using chi square and ANOVA.

RESULTS

Majority of the patients were females; hailing from rural area; unskilled professional; educated up to below primary level; were single and Hindu by religion. Most common metabolic abnormality was low HDL in 76.6%; High TGs in 26.6%; High SBP ≥130mm Hg in 16.67%; DBP>85mm Hg in 13.33%; High FBS 10% of the patients. In risk assessment strongest risk factors for metabolic syndrome were high waist circumference, FBS and TGs. BMI, total cholesterol, LDL and VLDL were also observed as a risk factors in drug naïve schizophrenic patients.

CONCLUSION

HDL, FBS, TGs, waist circumference and BMI are all the strong risk factors for development of metabolic syndrome in drug naïve schizophrenia patients.
