Abstract
Background Depression shows different patterns depending on socioeconomic status (SES) and metabolic syndrome (MS). However, the nature of this association remains poorly understood. The aim of this study was to examine whether the combination of MS and lower SES was associated with the prevalence of depression, based on data from the Korea National Health and Nutrition Examination Survey (KNHANES). Methods Data were obtained from a cross-sectional study of 24,102 adults (> 19 years of age) who participated in the KNHANES during 2008–2013 and for whom MS and depression data were available. MS was defined using the diagnostic criteria of the modified National Cholesterol Education Program Adult Treatment Panel III. Measure of depression was ascertained from self-reports of physician diagnosis. Multiple logistic regression analysis was used to evaluate the association between depression and MS as well as SES (alone and in combination). Results Overall, 622 of the 24,102 subjects (2.6%) met the criteria for depression. The prevalence of depression was associated with MS, a lower high-density lipoprotein cholesterol level, an elevated triglyceride level, a lower education level, and a lower household income. Participants with MS and a low SES had a higher likelihood of depression than those without MS and a high SES (odds ratio [OR] = 4.180 for low education level and OR = 3.994 for low household income level). Conclusions This study suggests that the combination of SES and MS may play an important role in depression, which has implications for healthcare policy and depression management.

THE SCIENCE OF THE TOTAL ENVIRONMENT 2020; 714:136811.

Abstract
To test the relationship not yet explored before among earthquake and related environmental factors, low-density lipoprotein receptor (LDLR) and posttraumatic stress disorder (PTSD), the genetic variation of LDLR rs5925 was selected and PTSD was examined by PTSD Checklist-Civilian Version (PCLC) in adolescents with different genotypes of LDLR rs5925 longitudinally at 6, 12 and 18 months after the 2008 Wenchuan earthquake. The C allele carriers were observed to have higher PTSD prevalence than the TT homozygotes in the male subjects, and higher PTSD prevalence and PCL-C scores in the female subjects only at 6 months. When compared to that at 12 months, decreased PTSD prevalence was observed at 18 months only in the female C allele carriers, but not in the female TT homozygotes or the male subjects. The potential risk factors of PTSD and predictors of PCL-C scores were different during the follow-up. LDLR rs5925 was one of the predictors for PCL-C scores at 6 and 12 months, and one of the potential factors for PTSD prevalence at 6 months. These results suggest that interactions may occur between earthquakes and other related environmental factors, which could affect the relationship of LDLR rs5925 with PTSD and be considered for individualized treatment.

Abstract
The changes in regional facial skin blood flow and vascular conductance have been assessed for the first time with noninvasive two-dimensional laser speckle flowmetry during audiovisually elicited emotional challenges for 2 min (comedy, landscape, and horror movie) in 12 subjects. Limb skin blood flow and vascular conductance and systemic cardiovascular variables were simultaneously measured. The extents of pleasantness and consciousness for each emotional stimulus were estimated by the subjective rating from -5 (the most unpleasant; the most unconscious) to +5 (the most pleasant; the most conscious). Facial skin blood flow and vascular conductance, especially in the lips, decreased during viewing of comedy and horror movies, whereas they did not change during viewing of a landscape movie. The decreases in facial skin blood flow and vascular conductance were the greatest with the comedy movie. The changes in lip, cheek, and chin skin blood flow negatively correlated (P < 0.05) with the subjective ratings of pleasantness and consciousness. The changes in lip skin vascular conductance negatively correlated (P < 0.05) with the subjective rating of pleasantness, while the changes in infraorbital, subnasal, and chin skin vascular conductance negatively correlated (P < 0.05) with the subjective rating of consciousness. However, none of the changes in limb skin blood flow and vascular conductance and systemic hemodynamics correlated with the subjective ratings. The mental arithmetic task did not alter facial and limb skin blood flows, although the task influenced systemic cardiovascular variables. These findings suggest that the more emotional status becomes pleasant or conscious, the more neurally mediated vasoconstriction may occur in facial skin blood vessels.

Abstract
OBJECTS The present study aimed to investigate the relationship of plasma glutamate levels with the early-onset of post-stroke depression (PSD) and to further explore the prognostic value of plasma glutamate combined with clinical characteristics for the early-onset PSD in the acute ischemic stroke patients. METHODS Seventy-four patients who admitted to the hospital within 24h of acute ischemic stroke were consecutively recruited and followed up for 2weeks. The Beck Depression Inventory (BDI) and 17-item Hamilton Depression Rating Scale (HAMD-17) were used to screen for depressive symptoms 14days after stroke. Diagnoses of depression were made in accordance with DSM-IV. Plasma glutamate levels were determined by High Performance Liquid Chromatography (HPLC) on days 1 and 14 after stroke for all patients. RESULTS Plasma glutamate levels were significantly lower in PSD patients than those of non-PSD patients on day 1 after stroke. ROC curve analyses revealed an AUC (area under the ROC curve) of 0.724 (95% CI: 0.584-0.863, p=0.004) and of 0.669 (95% CI: 0.523-0.814, p=0.030) for National Institute of Health Stroke Scale (NIHSS) scores and plasma glutamate levels on day 1 respectively. Combined ROC analyses using the two factors revealed the highest AUC of 0.804 (95% CI: 0.685-0.922, P<0.0001). CONCLUSIONS These results indicated an association between the early-onset PSD and a low plasma glutamate level following acute ischemic stroke. The combination of reduced plasma glutamate levels and physical impairment (determined by NIHSS) 1day after acute ischemic stroke was a potential diagnostic indicator for early-onset PSD.

Abstract
AbstractBackgroundAutoantibodies have been implicated in the etiologic pathway of depressive disorders. Here, we determine the association between the presence of a panel of autoantibodies at baseline and change in depression symptom score over 5-year follow-up in a cohort of healthy elderly Australians.MethodsSerum samples from 2049 randomly selected subjects enrolled in the Hunter Community Study (HCS) aged 55–85 years were assayed for a range of autoimmune markers (anti-nuclear autoantibodies, extractable nuclear antigen autoantibodies, anti-neutrophil cytoplasmic autoantibodies, thyroid peroxidase autoantibodies, tissue transglutaminase autoantibodies, anti-cardiolipin autoantibodies, rheumatoid factor and cyclic citrullinated peptide autoantibodies) at baseline. Depression symptom score was assessed using the Centre for Epidemiological Study (CES-D) scale at baseline and 5 years later.ResultsAutoantibody prevalence varied amongst our sample with ANA being the most prevalent; positive in 16% and borderline in 36% of study population. No evidence for a relationship was found between change in CES-D score over time and any autoimmune marker. Statins and high cholesterol were significantly associated with change in CES-D score over time in univariate analysis; however, these were probably confounded since they failed to remain significant following multivariable analysis.ConclusionsAutoantibodies were not associated with change in CES-D score over time. These findings point to an absence of autoimmune mechanisms in the general population or in moderate cases of depression.

Abstract
We performed an updated meta-analysis to obtain a more precise estimation of the relationship between apolipoprotein E (ApoE) gene polymorphism and susceptibility to depression, as previous reports have been inconsistent. Twenty studies with 2286 depression patients and 3845 controls were included. Odds ratios (OR) with 95% confidence intervals (CI) were calculated to assess the association between ApoE gene polymorphism and depression using a random effects model. Results showed a significant association between ApoE gene polymorphism and susceptibility to depression in the overall population (ε2/ε3 genotype versus ε3/ε3: OR 0.76, 95% CI 0.59-0.99). Subgroup analyses indicated an association in the Caucasian population (ε2 allele versus ε3: OR 0.75, 95% CI 0.58-0.97) as well as in late-life depression (LLD) patients (ε3/ε4 genotype versus ε3/ε3: OR 1.34, 95% CI 1.07-1.68, and ε4 allele versus ε3: OR 1.30, 95% CI 1.06-1.59). We concluded that the ε2/ε3 genotype likely provided a protective effect against depression in the overall population and the ε2 allele acted as a protective factor for depression in the Caucasian population while the ε4 allele and ε3/ε4 genotype were associated with an increased risk of depression in the LLD subjects.

Abstract
The etiopathological consequences of diabetes and its imperative sequels have been explored extensively in the scientific arena of cardiovascular diabetology. Innumerable risk covariates and confounders have been delineated for the primary and secondary prevention of diabetes and cardiovascular diseases (CVD). However, an intricate interaction of depression on them has been largely overlooked. Depression influences and participates in each and every step that worsens the diabetic state for developing cardiovascular complications. The dilemma is that it coexists, remains silent and generally not considered as relevant clinical parameter amenable to intervention. In this review, it is highlighted that depression has strong association and linkages with both diabetes and CVD and it should be considered and diagnosed at every stage of the diabetes to CVD continuum. Careful attention to the diagnosis and management of these disease states would contribute in lessening the CVD burden of the society.

Abstract
OBJECTIVE We aimed to evaluate the hypothesis that the presence of an interaction between smoking and being overweight increases the risks of lifestyle-related diseases (hypertension, diabetes mellitus, dyslipidemia, and cardiovascular disease) in outpatients with mood disorders. METHODS In this cross-sectional survey, using data from 213 outpatients with mood disorders (95 men, 118 women), we calculated the adjusted odds ratios (ORs) with 95% confidence intervals (CIs) for each of hypertension, diabetes, dyslipedemia, and cardiovascular disease, using a binary logistic regression model; we then calculated the adjusted OR values for smokers and non-smokers with body mass indexes (BMIs) of <25 or ≥25 kg/m². Next, we examined the data for the presence of an interaction between smoking and being overweight, using three measures of additive interaction: relative excess risk due to the interaction (RERI), attributable proportion due to the interaction (AP), and the synergy index (S). RESULTS Smokers with BMI <25 kg/m² had a significantly lower risk of hypertension (OR 0.27, 95% CI 0.09-0.81) than non-smokers with BMI <25 kg/m² (reference group). Compared with the reference group, overweight non-smokers had a significantly higher risk (2.82, 1.34-6.19) of hypertension, and overweight smokers had a higher risk (4.43, 1.28-15.26) of hypertension and very high risks of diabetes (8.24, 2.47-27.42) and cardiovascular disease (13.12, 1.95-88.41). The highest RERI was derived from the relation with cardiovascular disease. The highest AP and S were derived from the relation with type 2 diabetes. There was no interaction of smoking and being overweight with dyslipidemia. CONCLUSION The presence of an interaction between smoking and being overweight exacerbates the risks of hypertension, diabetes, and cardiovascular disease in outpatients with mood disorders.

Abstract
This study was designed to test the extent to which depressive symptoms are associated with the presence of the metabolic syndrome (MS) and each of its components, and whether these relationships are gender dependent. Participants were apparently healthy employed men (N=2,355) and women (N=1,525) who underwent a routine health check between the years 2003 and 2005. We used logistic regression analysis, predicting the MS by depressive symptoms, as assessed by the Patient Health Questionnaire, and the following control variables: age, education, smoking status, physical exercise, anxiety, and burnout. As hypothesized, we found that depression among women, but not men, was associated with a 1.94-fold risk of having the MS, and with an elevated risk of having two of its five components: elevated waist circumference (odds ratio, OR=2.23) and elevated glucose levels (OR=2.44). In addition, a positive trend was observed toward an association with the other three components: low high-density lipoprotein, hypertension, and elevated triglycerides. Among men depression was associated with elevated waist circumference only (OR=1.77). These findings suggest that especially among women, the association between depression and cardiovascular diseases might be linked to metabolic processes. If replicated in longitudinal studies, these findings may have important health-care policy implications with regard to depression management interventions.

Abstract
OBJECTIVE This study aimed to clarify the relationship between the epsilon4 allele and late-life depression, taking into account lipid profile, vascular diseases, and sociodemographics. METHODS Using a multilevel stratified random sampling strategy, a total of 500 subjects aged 65 to 74 years were recruited for this cross-sectional study from the official household records of an entire county in southern Taiwan. Depressive symptoms were assessed by the Taiwanese Depression Questionnaire (TDQ). Cognitive function was assessed by the Short Portable Mental Status Questionnaire. Blood samples were collected for the determination of the apolipoprotein E (ApoE) polymorphism and the lipid profile. RESULTS A total of 283 subjects (58.7% male, with a mean age of 69.2 +/- 2.7 years) completed all questionnaires and collection of blood samples. Using the chi(2) test, the overall difference for frequency of the presence of the epsilon4 allele was significant among the severe group (TDQ score >18), moderate group (TDQ score 9-18), and mild group (TDQ score <9). The proportion of history of heart disease was significantly higher in the severe group than in the mild or moderate group. Kruskal-Wallis statistics revealed that the mean total and low-density lipoprotein cholesterol levels were significantly higher in the severe group than in the moderate or mild group. With our two-level four-class latent class regression model, the presence of the epsilon4 allele was significantly associated with the severely depressed group as compared to the nondepressed group, adjusting for vascular diseases and lipid profile. CONCLUSION The ApoE epsilon4 allele may be correlated with severe depression in the elderly through ways other than the "vascular depression" hypothesis.

Abstract
Previous research has assessed the relationship between blood lipid levels and depression with contradictory results. Several studies have linked low cholesterol levels with impulsive, aggressive and suicidal behaviours. The aim of this pilot study was to examine serum lipids in a sample of patients suffering from seasonal affective disorder (SAD). We conducted a retrospective analysis of data on total serum cholesterol and serum triglycerides in 39 SAD patients and 40 non-seasonally depressed or schizophrenic control subjects. Study subjects had to be free of psychotropic drugs for at least 2 weeks. Analysis of covariance (ANCOVA) was performed to assess group differences. After adjustment for significant covariates SAD patients had significantly lower total cholesterol levels (5.21 +/- 1.14 mmol/l) than control subjects (5.94 +/- 1.11 mmol/l; p = 0.013). Moreover, hypercholesterolemia (total cholesterol > 5.20 mmol/l) was significantly less frequent in the SAD group (46.2%) than in the control group (75.0%; p = 0.012). Total serum triglycerides did not differ significantly between SAD patients (1.54 +/- 1.07 mmol/l) and controls (1.56 +/- 0.96 mmol/l; p = 0.126). The results of this study support the idea that low cholesterol levels may be of pathogenetic importance in SAD. Further study in larger clinical samples is warranted to clarify our findings.

Abstract
To examine gender-related differences in somatization among workers, 490 Japanese municipal office employees (248 women) completed the Medical Symptom Checklist, Somatosensory Amplification Scale (SSAS), and Profile of Mood States (POMS), along with questionnaires on their working environment. In women, SSAS scores were positively associated with perceived work stress, and negatively with social support levels (both p < 0.01). Female sex was significantly associated with SSAS scores (p < 0.01), controlling for the effects of total somatic symptom count, POMS tension-anxiety and depression scores, perceived working stress, and social support. The phenomenon of somatosensory amplification might be essential in estimating gender-specific symptoms in a working population.

Abstract
Although it has been argued that those with lower levels of serum cholesterol are likely to be depressive, the findings are inconsistent. The present study attempted to clarify the relationship between major depression and serum total cholesterol in a working population. Subjects were 987 Japanese men working at an institute, aged 20 to 64 years. In addition to blood examinations and physical measurements, clinical structured interviews of the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) were used to detect major depression. The prevalence of major depression was higher in the hypercholesterolemics (serum total cholesterol levels > or = 5.69 mmol/liter) than in the normocholesterolemics (3.10-5.69 mmol/liter) (6.1% vs 1.8%, p < 0.05). Notably, there was no case with major depression among the hypocholesterolemics (< 3.10 mmol/liter). Through a multiple regression analysis, serum total cholesterol levels were positively predicted by the following four variables: major depression, age, body mass index, and skipping breakfast (all p < 0.01). Concerning those diagnosed with major depression, serum total cholesterol levels remained higher in the following year (p < 0.05), comparing to those without such diagnosis. Therefore, depression is associated with higher serum cholesterol levels in a population of Japanese male workers. The irregularity of eating behavior may be one of the factors mediating high serum cholesterol levels and major depression.

Abstract
This study examined the relationship between arterial stiffness and autonomic nervous function in a young population. A cross-sectional study was conducted on 382 Japanese males, aged 24 to 39 years, who worked at the same information service company. Brachial-ankle pulse wave velocity (baPWV) was measured using an automatic waveform analyzer, and the spectral power of heart rate variability in the low frequency (LF: 0.04-0.15 Hz) and the high frequency (HF: 0.15-0.40 Hz) band was evaluated by the maximum entropy method. LF/HF and HF were used as the indicators of sympathetic and parasympathetic nervous activity, respectively. Psycho-hormonal responses were examined by the Profile of Mood State (tension-anxiety and anger-hostility scales) and Hamilton's Depression Scale with serum cortisol and catecholamine levels. In a univariate analysis, baPWV was positively associated with the following variables (all p <0.05): LF/HF, age, body mass index, systolic and diastolic blood pressures, heart rate, serum total cholesterol and triglycerides, blood glucose, and plasma cortisol and noradrenaline. Multiple regression analysis indicated that LF/HF was an independent predictor of baPWV (p <0.05), after controlling for significant effects of age, systolic blood pressure, and plasma noradrenaline levels. There was no significant effect of HF on baPWV in this multivariate analysis. Neither mood state nor health-related lifestyle factors such as smoking were significant. It was suggested that baPWV is closely associated with sympathetic nervous activity in young men.
