Abstract
Background Pheochromocytomas and paragangliomas (PPGL) are neuroendocrine tumors that originate from adrenal medulla or extra-adrenal chromaffin cells, respectively. They produce an excess of catecholamines and their metabolites. Abnormal levels of these biomolecules have been also found in pediatric patients with neuroblastoma (NB). Due to the diurnal fluctuation, the laboratory practice recommends the determination of biogenic amines in acidified 24-h urine samples. However, the collection and acidification of specimens cannot be performed easily, especially for children. Spot urines represent an attractive alternative for the detection of catecholamines and corresponding metabolites. Methods In our study, we enrolled 50 patients with symptoms related to PPGL and we determined the concentration values for both spot and 24-h urine samples using high-performance liquid chromatography tandem mass spectrometry (HPLC/MS-MS). Since day variations of the urinary concentration are due to fluctuations in renal excretion rather than in production, we normalized the concentration of biogenic amines in spot urine and in 24-h urine collection to urinary creatinine concentration. A correlation study between the normalized levels of biogenic amines was performed using a linear regression analysis model and Pearson's correlation coefficients. Results We obtained a good correlation of values which suggests an interchangeability of the 24-h and random urine samples. Only for epinephrine a weak correlation was determined. Conclusions Our findings suggest that the sample collection as single spot urine may replace 24-h collection for the detection of urinary biogenic amines by HPLC/MS-MS.

Impact of 24 h shifts on urinary catecholamine in emergency physicians: a cross-over randomized trial. Sci Rep 2024; 14:7329. [PMID: 38538760 PMCID: PMC10973468 DOI: 10.1038/s41598-024-58070-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2023] [Accepted: 03/25/2024] [Indexed: 04/01/2024] Open
Abstract
24-h shift (24 hS) exposed emergency physicians to a higher stress level than 14-h night shift (14 hS), with an impact spreading on several days. Catecholamines are supposed to be chronic stress biomarker. However, no study has used catecholamines to assess short-term residual stress or measured them over multiple shifts. A shift-randomized trial was conducted to study urinary catecholamines levels of 17 emergency physicians during a control day (clerical work on return from leave) and two working day (14 hS and 24 hS). The Wilcoxon matched-pairs test was utilized to compare the mean catecholamine levels. Additionally, a multivariable generalized estimating equations model was employed to further analyze the independent relationships between key factors such as shifts (compared to control day), perceived stress, and age with catecholamine levels. Dopamine levels were lower during 24 hS than 14 hS and the control day. Norepinephrine levels increased two-fold during both night shifts. Epinephrine levels were higher during the day period of both shifts than on the control day. Despite having a rest day, the dopamine levels did not return to their normal values by the end of the third day after the 24 hS. The generalized estimating equations model confirmed relationships of catecholamines with workload and fatigue. To conclude, urinary catecholamine biomarkers are a convenient and non-invasive strong measure of stress during night shifts, both acutely and over time. Dopamine levels are the strongest biomarker with a prolonged alteration of its circadian rhythm. Due to the relation between increased catecholamine levels and both adverse psychological effects and cardiovascular disease, we suggest that emergency physicians restrict their exposure to 24 hS to mitigate these risks.

Abstract
The adrenal glands are key components of the mammalian endocrine system, helping maintain physiological homeostasis and the coordinated response to stress. Each adrenal gland has two morphologically and functionally distinct regions, the outer cortex and inner medulla. The cortex is organized into three concentric zones which secrete steroid hormones, including aldosterone and cortisol. Neural crest-derived chromaffin cells in the medulla are innervated by preganglionic sympathetic neurons and secrete catecholamines (epinephrine, norepinephrine) and neuropeptides into the bloodstream, thereby functioning as the neuroendocrine arm of the sympathetic nervous system. In this article we review serotonin (5-HT) and the serotonin transporter (SERT; SLC6A4) in the adrenal gland. In the adrenal cortex, 5-HT, primarily sourced from resident mast cells, acts as a paracrine signal to stimulate aldosterone and cortisol secretion through 5-HT4/5-HT7 receptors. Medullary chromaffin cells contain a small amount of 5-HT due to SERT-mediated uptake and express 5-HT1A receptors which inhibit secretion. The atypical mechanism of the 5-HT1A receptors and interaction with SERT fine tune this autocrine pathway to control stress-evoked catecholamine secretion. Receptor-independent signaling by SERT/intracellular 5-HT modulates the amount and kinetics of transmitter release from single vesicle fusion events. SERT might also influence stress-evoked upregulation of tyrosine hydroxylase transcription. Transient signaling via 5-HT3 receptors during embryonic development can limit the number of chromaffin cells found in the mature adrenal gland. Together, this emerging evidence suggests that the adrenal medulla is a peripheral hub for serotonergic control of the sympathoadrenal stress response.

Abstract
Statins are commonly prescribed medications widely investigated for their potential actions on the brain and mental health. Pre-clinical and clinical evidence suggests that statins may play a role in the treatment of depressive disorders, but only the latter has been systematically assessed. Thus, the physiopathological mechanisms underlying statins' putative antidepressant or depressogenic effects have not been established. This review aims to gather available evidence from mechanistic studies to strengthen the pharmacological basis for repurposing statins in depression. We used a broad, well-validated search strategy over three major databases (Pubmed/MEDLINE, Embase, PsychINFO) to retrieve any mechanistic study investigating statins' effects on depression. The systematic search yielded 8068 records, which were narrowed down to 77 relevant papers. The selected studies (some dealing with more than one bodily system) described several neuropsychopharmacological (44 studies), endocrine-metabolic (17 studies), cardiovascular (6 studies) and immunological (15 studies) mechanisms potentially contributing to the effects of statins on mood. Numerous articles highlighted the beneficial effect of statins on depression, particularly through positive actions on serotonergic neurotransmission, neurogenesis and neuroplasticity, hypothalamic-pituitary axis regulation and modulation of inflammation. The role of other mechanisms, especially the association between statins, lipid metabolism and worsening of depressive symptoms, appears more controversial. Overall, most mechanistic evidence supports an antidepressant activity for statins, likely mediated by a variety of intertwined processes involving several bodily systems. Further research in this area can benefit from measuring relevant biomarkers to inform the selection of patients most likely to respond to statins' antidepressant effects while also improving our understanding of the physiopathological basis of depression.

Abstract
OBJECTIVE Posttraumatic stress disorder (PTSD) is associated with elevated risk of coronary heart disease (CHD); however, the effects of PTSD treatment on CHD biomarkers is unknown. This study examined whether cognitive processing therapy (CPT) improves 24-hourheart rate variability (HRV), a predictor of CHD mortality. METHODS Individuals between the ages of 40 and 65 years with PTSD (n = 112) were randomized to receive 12 sessions of CPT or a Waiting List (WL) intervention comprised of 6 weekly telephone checks of emotional status. The primary outcome variable was 24-hour HRV estimated from the standard deviation of all normal R-R intervals (SDNN); secondary outcomes were the root mean square of successive differences between heart beats (RMSSD), low-frequency HRV (LF-HRV) and high-frequency HRV (HF-HRV). Secondary outcomes also included 24-hour urinary catecholamine excretion, plasma C-reactive protein (CRP), and flow-mediated dilation (FMD) of the brachial artery. For outcomes, linear mixed longitudinal models were used to estimate mean differences (Mdiff). RESULTS Participants randomized to the CPT group did not show improved SDNN (Mdiff = 9.8; 95%CI, -2.7 to 22.3; p = 0.12), the primary outcome variable, but showed improved RMSSD (Mdiff = 3.8; 95% CI, 0.5 to 7.1; p = 0.02), LF- HRV (Mdiff =0.3; 95% CI, 0.1 to 0.5; p = 0.01), and HF-HRV (Mdiff = 0.3; 95% CI, 0.0 to 0.6; p = 0.03) compared to WL. There were no differences between groups in catecholamine excretion, FMD, or inflammatory markers. CONCLUSION Treating PTSD may not only improve quality of life but may also help ameliorate heightened CHD risk characteristics of PTSD.

Abstract
5-Hydroxytryptamine (5-HT), or serotonin, plays a crucial role as a neuromodulator and/or neurotransmitter of several nervous system functions. Its actions are complex, and depend on multiple factors, including the type of effector or receptor activated. Briefly, 5-HT can activate: (i) metabotropic (G-protein-coupled) receptors to promote inhibition (5-HT1, 5-HT5) or activation (5-HT4, 5-HT6, 5-HT7) of adenylate cyclase, as well as activation (5-HT2) of phospholipase C; and (ii) ionotropic receptor (5-HT3), a ligand-gated Na+/K+ channel. Regarding blood pressure regulation (and beyond the intricacy of central 5-HT effects), this monoamine also exerts direct postjunctional (on vascular smooth muscle and endothelium) or indirect prejunctional (on autonomic and sensory perivascular nerves) effects. At the prejunctional level, 5-HT can facilitate or preclude the release of autonomic (e.g., noradrenaline and acetylcholine) or sensory (e.g., calcitonin gene-related peptide) neurotransmitters facilitating hypertensive or hypotensive effects. Hence, we cannot formulate a specific impact of 5-HT on blood pressure level, since an increase or decrease in neurotransmitter release would be favoured, depending on the type of prejunctional receptor involved. This review summarizes and discusses the current knowledge on the prejunctional mechanisms involved in blood pressure regulation by 5-HT and its impact on some vascular-related diseases.

Abstract
The link between the autonomic nervous system and tumor biology is being unfold. We aim to study the contribution of genes of the adrenergic (ADBR2 - rs1042713, NM_000024.6:c.46G>A, NP_000015.2:p. Gly16Arg), cholinergic (CHRNA5 - rs16969968, NM_000745.3:c.1192G>A, NP_000736.2:p.Asp398Asn), and serotonergic systems (SLC6A4 - 5-HTTVNTR-intron2, HTR2A - rs6313, NM_000621.5:c.102C>T, NP_ 001365853 .1: p. Ser 34=) to gynecological tumorigenesis and their treatment by embolization. A total of 517 DNA samples from women were analyzed. Samples were genotyped by PCR, PCR-RFLP and EndPoint genotyping. Results show a statistically significant association between the AA genotype of the ADBR2 gene and GG genotype of the CHRNA5 gene with leiomyoma (OR = 2.311; p = 0.003 and OR = 2.165; p = 0.001, respectively), and the epistatic interaction between genotypes increases the risk (OR = 2.458; p= 0.043). The GG genotype (CHRNA5) shows a lower reduction of the volume of the main leiomyoma after treatment (p=0.015). Combination of the genotypes 12/12-AA (SLC6A4 - ADBR2) increases the risk to leiomyoma (OR = 2.540, p= 0.030). TT genotype of HTR2A gene in combination with any of the two risk genotypes (of ADBR2 or CHRNA5) increases substantially the risk (OR = 5.266, p = 0.006; OR = 6.364, p=0.007, respectively). We conclude that ADBR2 and CHRNA5 genes have a relevant role that is enhanced by the epistatic relationship with the genes HTR2A and SLC6A4. CHRNA5 gene may also be a modulator of the success of embolization. We confirm the contribution of the genetics of Autonomous Nervous System to tumor biology.

Abstract
The stress response to emotions elicits the release of glucocorticoids from the adrenal cortex, epinephrine from the adrenal medulla, and norepinephrine from the sympathetic nerves. The baroreflex adapts to buffer these responses to ensure that perfusion to the organs meets the demands while maintaining blood pressure within a within a narrow range. While stressor-evoked autonomic cardiovascular responses may be adaptive for the short-term, the recurrent exaggerated cardiovascular stress reactions can be maladaptive in the long-term. Prolonged stress or loss of the baroreflex's buffering capacity can predispose episodes of heightened sympathetic activity during stress leading to hypertension, tachycardia, and ventricular wall motion abnormalities. This review discusses 1) how the baroreflex responds to acute and chronic stressors, 2) how lesions in the neuronal pathways of the baroreflex alter the ability to respond or counteract the stress response, and 3) the techniques to assess baroreflex sensitivity and stress responses. Evidence suggests that loss of baroreflex sensitivity may predispose heightened autonomic responses to stress and at least in part explain the association between stress, mortality and cardiovascular diseases.

OBJECTIVE To determine whether exercise and escitalopram are better than placebo in reducing symptoms of anxiety as measured by the Hospital Anxiety and Depression-Anxiety Subscale (HADS-A) and in improving CHD risk biomarkers. DESIGN, SETTING, AND PARTICIPANTS This randomized clinical trial was conducted between January 2016 and May 2020 in a tertiary care teaching hospital in the US and included 128 outpatients with stable CHD and a diagnosed anxiety disorder or a HADS-A score of 8 or higher who were older than 40 years, sedentary, and not currently receiving mental health treatment. INTERVENTIONS Twelve weeks of aerobic exercise 3 times per week at an intensity of 70% to 85% heart rate reserve, escitalopram (up to 20 mg per day), or placebo pill equivalent. MAIN OUTCOMES AND MEASURES The primary outcome was HADS-A score. CHD biomarkers included heart rate variability, baroreflex sensitivity, and flow-mediated dilation, along with 24-hour urinary catecholamines. RESULTS The study included 128 participants. The mean (SD) age was 64.6 (9.6) years, and 37 participants (29%) were women. Participants randomized to the exercise group and escitalopram group reported greater reductions in HADS-A (exercise, -4.0; 95% CI, -4.7 to -3.2; escitalopram, -5.7; 95% CI, -6.4 to -5.0) compared with those randomized to placebo (-3.5; 95% CI, -4.5 to -2.4; P = .03); participants randomized to escitalopram reported less anxiety compared with those randomized to exercise (-1.67; 95% CI, -2.68 to -0.66; P = .002). Significant postintervention group differences in 24-hour urinary catecholamines were found (exercise z score = 0.05; 95% CI, -0.2 to 0.3; escitalopram z score = -0.24; 95% CI, -0.4 to 0; placebo z score = 0.36; 95% CI, 0 to 0.7), with greater reductions in the exercise group and escitalopram group compared with the placebo group (F1,127 = 4.93; P = .01) and greater reductions in the escitalopram group compared with the exercise group (F1,127 = 4.37; P = .04). All groups achieved comparable but small changes in CHD biomarkers, with no differences between treatment groups. CONCLUSIONS AND RELEVANCE Treatment of anxiety with escitalopram was safe and effective for reducing anxiety in patients with CHD. However, the beneficial effects of exercise on anxiety symptoms were less consistent. Exercise and escitalopram did not improve CHD biomarkers of risk, which should prompt further investigation of these interventions on clinical outcomes in patients with anxiety and CHD. TRIAL REGISTRATION ClinicalTrials.gov Identifier: NCT02516332.

Abstract
BACKGROUND Experiences of discrimination are a risk factor for subsequent cardiovascular disease. However, there is a lack of longitudinal research examining associations between discrimination and urinary catecholamines. This is surprising given the likely mediating role of sympathetic nervous system dysregulation in the association between psychosocial stress and cardiovascular morbidity. PURPOSE The current study examined the 3 year longitudinal association between experiences of discrimination and urinary catecholamines. METHODS The sample included 149 college students (mean age at baseline = 18.8, standard deviation = 0.96; 45% Black/African American; 55% White/European American). Concentrations of epinephrine and norepinephrine-urinary catecholamines with established links to psychosocial stress exposure and subsequent morbidity-were determined from 12 hr overnight samples. RESULTS Results indicated that experiences of discrimination were associated with increases in both epinephrine (β = .284, standard error [SE] = .117, p = .015) and norepinephrine (β = .306, SE = .114, p = .001). These longitudinal associations persisted after adjusting for negative affect, depression, and rejection sensitivity and did not vary as a function of race/ethnicity. CONCLUSIONS Results suggest that examination of overnight urinary catecholamines as a biological mediator of associations between experiences of discrimination and cardiovascular morbidity is warranted.

Abstract
UPLC-MS/MS methods are the gold standard for routine, high-throughput measurements of biogenic monoamines for the diagnosis of catecholamine-producing tumors. However, this cannot be achieved without employing efficient sample pretreatment methods. Therefore, two pretreatment methods, thin-film solid phase microextraction (TF-SPME) and packed fibers solid phase extraction (PFSPE), were developed and evaluated for the analysis of biogenic monoamines and their metabolites in urine. A hydrophilic-lipophilic balance (HLB) coating was chosen for the thin-film blade format SPME method and compared with a Polycrown ether (PCE) composite nanofiber used as an adsorbent for the PFSPE method. Under optimal conditions, the absolute extraction recovery and relative matrix effect of the newly developed TF-SPME method were determined to be 35.7-74.8% and 0.47-3.63%, respectively. The linearity was 0.25-500 ng mL-1 for norepinephrine, epinephrine, dopamine, normetanephrine 3-methoxytyramine, serotonin, histamine, and 0.1-500 ng mL-1 for metanephrine. The intra-and inter-assay coefficients of variation were 0.7-8.7%, and the respective accuracies were calculated to be 90.8-104.7% and 89.5-104.5% for TF-SPME. Compared with the PFSPE method, the TF-SPME method had a higher extraction efficiency, lower matrix effects and a wider linear range for eight target substances, which ensured higher accuracy of simultaneous detection of all compounds of interest. Therefore, the proposed TF-SPME method can be employed for the high throughput screening for neuroendocrine tumors in a routine clinical setting and other relative research by simultaneous quantitation of urine eight biological monoamines in a single run.

Abstract
Depression and anxiety can significantly reduce the effectiveness of cardiac rehabilitation (CR). Several studies have assessed the effectiveness of virtual reality (VR)-based interventions for symptoms of anxiety and depression; however, they do not relate to patients with heart disease. The aim of this study was to assess the effects of VR therapy on the mental state of patients with coronary artery disease (CAD). Thirty-four CAD patients with elevated anxiety or depression symptoms were recruited. After randomization, 17 participants were assigned to the intervention group, and 17 to the control group. Both groups underwent standard CR for outpatients. In the intervention group, eight VR therapy sessions were applied. In the control group, eight sessions of Schultz' Autogenic Training were applied. To assess patient mental states, Hospital Anxiety and Depression Scale (HADS) and Perception of Stress Questionnaire (PSQ) were used, before and after 4 weeks of CR. In the intervention group, a significant decrease in HADS score was observed (19.46 pretreatment vs. 15.73 post-treatment, p = 0.003), HADS-Anxiety subscale decreased by 16.0 percent (p = 0.01) and HADS-Depression by 23.0 percent (p = 0.003). Similarly, a significant decrease in PSQ was recorded at 12.8 percent (64.73 vs. 56.47, p = 0.03). In the control group, HADS and PSQ data did not change. VR therapy significantly reduced the severity of depressive symptoms, anxiety, and stress levels in CAD patients undergoing CR. Immersive VR therapy effectively supports the CR of individuals with anxiety-depressive symptoms. ClinicalTrials.gov (NCT04045977).

Abstract
Depression is a major cause of morbidity and low quality of life among patients with cardiovascular disease (CVD), and it is now considered as an independent risk factor for major adverse cardiovascular events. Increasing evidence indicates not only that depression worsens the prognosis of cardiac events, but also that a cross-vulnerability between the two conditions occurs. Among the several mechanisms proposed to explain this interplay, platelet activation is the more attractive, seeing platelets as potential mirror of the brain function. In this review, we dissected the mechanisms linking depression and CVD highlighting the critical role of platelet behavior during depression as trigger of cardiovascular complication. In particular, we will discuss the relationship between depression and molecules involved in the CVD (e.g., catecholamines, adipokines, lipids, reactive oxygen species, and chemokines), emphasizing their impact on platelet activation and related mechanisms.

Abstract
Idiopathic oedema is a syndrome affecting primarily women that is characterized by frustrating intermittent fluid retention, with hallmarks of obesity, periodic oedema, anxiety, and a susceptibility to develop type 2 diabetes. Management is typically reassurance and weight control, with no known drug class proven to provide consistent relief. We hypothesise that sodium-glucose cotransporter 2 inhibition is a logical intervention in the treatment of idiopathic oedema, having effects on obesity, blood pressure, impaired glucose tolerance, sympathetic overdrive, and reduction in swelling - the most common and distressing complaint. Sodium-glucose cotransporter 2 inhibition by promoting greater electrolyte-free, but glucose driven, water clearance with preferential fluid clearance from the interstitial space, without compromising intravascular volume, may provide symptomatic relief of swelling and bloating. The consequent weight reduction secondary to caloric loss from renal glycosuria and decreased adiposity would prevent disease progression of type 2 diabetes or pre-diabetes. With diminished adrenergic output from central and peripheral autonomic influences, reduction of blood pressure occurs, and by similar mechanisms, anxiety may be reduced.

Abstract
Background Exposure to green vegetation has been linked to positive health, but the pathophysiological processes affected by exposure to vegetation remain unclear. To study the relationship between greenness and cardiovascular disease, we examined the association between residential greenness and biomarkers of cardiovascular injury and disease risk in susceptible individuals. Methods and Results In this cross-sectional study of 408 individuals recruited from a preventive cardiology clinic, we measured biomarkers of cardiovascular injury and risk in participant blood and urine. We estimated greenness from satellite-derived normalized difference vegetation index ( NDVI ) in zones with radii of 250 m and 1 km surrounding the participants' residences. We used generalized estimating equations to examine associations between greenness and cardiovascular disease biomarkers. We adjusted for residential clustering, demographic, clinical, and environmental variables. In fully adjusted models, contemporaneous NDVI within 250 m of participant residence was inversely associated with urinary levels of epinephrine (-6.9%; 95% confidence interval, -11.5, -2.0/0.1 NDVI ) and F2-isoprostane (-9.0%; 95% confidence interval, -15.1, -2.5/0.1 NDVI ). We found stronger associations between NDVI and urinary epinephrine in women, those not on β-blockers, and those who had not previously experienced a myocardial infarction. Of the 15 subtypes of circulating angiogenic cells examined, 11 were inversely associated (8.0-15.6% decrease/0.1 NDVI ), whereas 2 were positively associated (37.6-45.8% increase/0.1 NDVI ) with contemporaneous NDVI . Conclusions Independent of age, sex, race, smoking status, neighborhood deprivation, statin use, and roadway exposure, residential greenness is associated with lower levels of sympathetic activation, reduced oxidative stress, and higher angiogenic capacity.

Abstract
Adrenal chromaffin cells comprise the neuroendocrine arm of the sympathetic nervous system and secrete catecholamines to coordinate the appropriate stress response. Deletion of the serotonin (5-HT) transporter (SERT) gene in mice (SERT-/- mice) or pharmacological block of SERT function in rodents and humans augments this sympathoadrenal stress response (epinephrine secretion). The prevailing assumption is that loss of CNS SERT alters central drive to the peripheral sympathetic nervous system. Adrenal chromaffin cells also prominently express SERT where it might coordinate accumulation of 5-HT for reuse in the autocrine control of stress-evoked catecholamine secretion. To help test this hypothesis, we have generated a novel mouse model with selective excision of SERT in the peripheral sympathetic nervous system (SERTΔTH), generated by crossing floxed SERT mice with tyrosine hydroxylase Cre driver mice. SERT expression, assessed by western blot, was abolished in the adrenal gland but not perturbed in the CNS of SERTΔTH mice. SERT-mediated [3H] 5-HT uptake was unaltered in midbrain, hindbrain, and spinal cord synaptosomes, confirming transporter function was intact in the CNS. Endogenous midbrain and whole blood 5-HT homeostasis was unperturbed in SERTΔTH mice, contrasting with the depleted 5-HT content in SERT-/- mice. Selective SERT excision reduced adrenal gland 5-HT content by ≈ 50% in SERTΔTH mice but had no effect on adrenal catecholamine content. This novel model confirms that SERT expressed in adrenal chromaffin cells is essential for maintaining wild-type levels of 5-HT and provides a powerful tool to help dissect the role of SERT in the sympathetic stress response.

Abstract
Objectives: Cardiac repolarization may be affected by psychiatric disorders and/or antidepressant use, but evidence for this is inconclusive. This study examined the relationship between depressive and anxiety disorder and use of antidepressants with T-wave amplitude (TWA) and QT-interval. Methods: Data was obtained from the Netherlands Study of Depression and Anxiety (n = 1,383). Depression/anxiety was diagnosed with the DSM-IV based Composite International Diagnostic Interview. The use of tricyclic antidepressants (TCAs), selective serotonin and noradrenalin reuptake inhibitors (SNRIs), and selective serotonin reuptake inhibitors (SSRIs) was established. T-wave amplitude and QT-interval corrected for heart rate (QTc) were obtained from an ECG measured in a type II axis configuration. Results: Compared to controls, persons with depression or anxiety disorders did not show a significantly different TWA (p = 0.58; Cohen's d = 0.046) or QTc (p = 0.48; Cohen's d = −0.057). In spite of known sympathomimetic effects, TCA use (p = 0.26; Cohen's d = −0.162) and SNRI use (p = 0.70; Cohen's d = −0.055) were not significantly associated with a lower TWA. TCA use (p = 0.12; Cohen's d = 0.225) and SNRI use (p = 0.11; Cohen's d = 0.227) were also not significantly associated with a prolonged QTc. Conclusion: We did not find evidence that either depressive/anxiety disorder or antidepressant use is associated with abnormalities in TWA or QTc. Earlier found sympathomimetic effects of TCAs and SNRIs are not evident in these measures of cardiac repolarization.

[PMID: 29355598 DOI: 10.1016/j.biotechadv.2018.01.009] [Citation(s) in RCA: 76] [Impact Index Per Article: 12.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2017] [Revised: 01/12/2018] [Accepted: 01/15/2018] [Indexed: 12/22/2022]
Abstract
Recent studies have suggested that certain (-)-epicatechin-containing foods have a blood pressure-lowering capacity. The mechanisms underlying (-)-epicatechin action may help prevent oxidative damage and endothelial dysfunction, which have both been associated with hypertension and certain brain disorders. Moreover, (-)-epicatechin has been shown to modify metabolic profile, blood's rheological properties, and to cross the blood-brain barrier. Thus, (-)-epicatechin causes multiple actions that may provide unique synergy beneficial for cardiovascular and neuropsychological health. This review summarises the current knowledge on the biological actions of (-)-epicatechin, related to cardiovascular and brain functions, which may play a remarkable role in human health and longevity.

Abstract
BACKGROUND The women Veteran population accessing Veterans Health Administration (VA) care has grown rapidly. Women Veterans exhibit high rates of mental health conditions that increase coronary artery disease (CAD) risk; however, the relationship between specific conditions and increasing mental health burden to CAD in this population is unknown. MATERIALS AND METHODS Using VA National Patient Care Data for 2009, we identified women Veterans over 45 (N = 157,195). Logistic regression models examined different mental health diagnoses and increasing mental health burden (number of diagnostic clusters) as predictors of CAD. RESULTS CAD prevalence was 4.16%, and 36% of women Veterans were current smokers. Depression exhibited the strongest association with CAD (odds ratio [OR] 1.60, 95% confidence interval [CI] [1.50-1.71]), similar to that of current smoking (OR 1.68 [1.58-1.78]). Controlling for demographic variables, smoking, diabetes, and obesity, each additional mental health diagnosis increased the odds of CAD by 44%. CONCLUSIONS Women Veterans over age 45 accessing VA care exhibited a high degree of mental health burden, which is associated with elevated odds of CAD; those with depression alone had 60% higher odds of CAD. For women Veterans using VA, mental health diagnoses may act as CAD risk factors that are potentially modifiable. Novel interventions in primary care and mental health are needed to address heart disease in this growing and aging population.

Abstract
Serotonin (5-HT) is an important neurotransmitter in the central nervous system where it modulates circuits involved in mood, cognition, movement, arousal, and autonomic function. The 5-HT transporter (SERT; SLC6A4) is a key regulator of 5-HT signaling, and genetic variations in SERT are associated with various disorders including depression, anxiety, and autism. This review focuses on the role of SERT in the sympathetic nervous system. Autonomic/sympathetic dysfunction is evident in patients with depression, anxiety, and other diseases linked to serotonergic signaling. Experimentally, loss of SERT function (SERT knockout mice or chronic pharmacological block) has been reported to augment the sympathetic stress response. Alterations to serotonergic signaling in the CNS and thus central drive to the peripheral sympathetic nervous system are presumed to underlie this augmentation. Although less widely recognized, SERT is robustly expressed in chromaffin cells of the adrenal medulla, the neuroendocrine arm of the sympathetic nervous system. Adrenal chromaffin cells do not synthesize 5-HT but accumulate small amounts by SERT-mediated uptake. Recent evidence demonstrated that 5-HT1A receptors inhibit catecholamine secretion from adrenal chromaffin cells via an atypical mechanism that does not involve modulation of cellular excitability or voltage-gated Ca2+ channels. This raises the possibility that the adrenal medulla is a previously unrecognized peripheral hub for serotonergic control of the sympathetic stress response. As a framework for future investigation, a model is proposed in which stress-evoked adrenal catecholamine secretion is fine-tuned by SERT-modulated autocrine 5-HT signaling.

Improvement in health-related quality of life after renal sympathetic denervation in real-world hypertensive patients: 12-month outcomes in the Global SYMPLICITY Registry. J Clin Hypertens (Greenwich) 2017; 19:833-839. [PMID: 28480523 DOI: 10.1111/jch.13007] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2016] [Revised: 01/27/2017] [Accepted: 02/13/2017] [Indexed: 01/21/2023]
Abstract
Renal denervation has been shown to reduce blood pressure in patients with uncontrolled hypertension, but less is known about its impact on quality of life. This analysis evaluated 12-month blood pressure and quality of life outcomes in 934 patients from the Global SYMPLICITY Registry who completed the EuroQoL five-dimensions three-level questionnaire (EQ-5D-3L). At baseline, 32% of patients reported anxiety/depression and 48% reported pain/discomfort. At 12 months (n=496), office and 24-hour ambulatory systolic blood pressure were reduced by 13.9±26.6 and 7.7±19.3 mm Hg, respectively, and 8% (P<.001) more patients reported no problems in anxiety/depression. Furthermore, numerically more patients reported no problems in pain/discomfort (4%, P=.08). Perceived health-related quality of life (visual analog scale) improved from baseline to 12 months (68±18 vs 73±17, P<.001), and the improvement was largest among patients with severe anxiety/depression at baseline (50±24 vs 64±22, P=.005 [n=32]). In this analysis, renal denervation was associated with a significant improvement in health-related quality of life, particularly anxiety/depression.

Abstract
OBJECTIVE Biomarkers are defined as anatomical, biochemical or physiological traits that are specific to certain disorders or syndromes. The objective of this paper is to summarise the current knowledge of biomarkers for anxiety disorders, obsessive-compulsive disorder (OCD) and posttraumatic stress disorder (PTSD). METHODS Findings in biomarker research were reviewed by a task force of international experts in the field, consisting of members of the World Federation of Societies for Biological Psychiatry Task Force on Biological Markers and of the European College of Neuropsychopharmacology Anxiety Disorders Research Network. RESULTS The present article (Part II) summarises findings on potential biomarkers in neurochemistry (neurotransmitters such as serotonin, norepinephrine, dopamine or GABA, neuropeptides such as cholecystokinin, neurokinins, atrial natriuretic peptide, or oxytocin, the HPA axis, neurotrophic factors such as NGF and BDNF, immunology and CO2 hypersensitivity), neurophysiology (EEG, heart rate variability) and neurocognition. The accompanying paper (Part I) focuses on neuroimaging and genetics. CONCLUSIONS Although at present, none of the putative biomarkers is sufficient and specific as a diagnostic tool, an abundance of high quality research has accumulated that should improve our understanding of the neurobiological causes of anxiety disorders, OCD and PTSD.

Generalized Anxiety Disorder and Hypoglycemia Symptoms Improved with Diet Modification. Case Rep Psychiatry 2016; 2016:7165425.

Abstract
Observational evidence suggests that a relationship may exist between high glycemic index diets and the development of anxiety and depression symptoms; however, as no interventional studies assessing this relationship in a psychiatric population have been completed, the possibility of a causal link is unclear. AB is a 15-year-old female who presented with concerns of generalized anxiety disorder and hypoglycemia symptoms. Her diet consisted primarily of refined carbohydrates. The addition of protein, fat, and fiber to her diet resulted in a substantial decrease in anxiety symptoms as well as a decrease in the frequency and severity of hypoglycemia symptoms. A brief return to her previous diet caused a return of her anxiety symptoms, followed by improvement when she restarted the prescribed diet. This case strengthens the hypothesis that dietary glycemic index may play a role in the pathogenesis or progression of mental illnesses such as generalized anxiety disorder and subsequently that dietary modification as a therapeutic intervention in the treatment of mental illness warrants further study.
