Associations of NT-proBNP and parameters of mental health in depressed coronary artery disease patients. Psychoneuroendocrinology 2018; 96:188-194.

Abstract
Natriuretic peptides (NP) are involved in the regulation of blood pressure and blood volume, and are elevated in patients with coronary artery disease (CAD). They are used as markers for illness severity, but their role in mental health is not well understood. Recently, A-type NP (ANP) has been associated with reduced anxiety in studies on cardiac patients; however, this study is the first to assess this effect for B-type NP (BNP) and for further dimensions of well-being and mental health. Depression, anxiety, and distress are more common in CAD patients than in the general population and are most likely not only influenced by psychological adaptation but also by neurobiological processes. We used baseline N-terminal proBNP (NT-proBNP) samples and psychometric assessments of 529 at least mildly depressed (Hospital Anxiety and Depression Scale, depression score ≥ 8) CAD patients from the multicenter Stepwise Psychotherapy Intervention for Reducing Risk in Coronary Artery Disease (SPIRR-CAD) trial. Psychosocial status was assessed using standardized self-rating questionnaires on anxiety, depression, coping with illness, vital exhaustion, type D personality, and quality of life. Separate linear regression models for each psychometric scale revealed significant negative correlations of NT-proBNP with anxiety, depression, vital exhaustion, depressive coping, and negative affectivity. Moreover, patients with higher levels of NT-proBNP experienced less bodily pain and had a better self-rated mental health, despite worse physical functioning. Linear regression adjusted for age, sex, and physical functioning (Short Form Health Survey [SF-36]) revealed NT-proBNP to be a significant predictor for all tested measures of the patients' psychosocial status. These results indicate that NT-proBNP is not only positively associated with greater disease severity in mildly to moderately depressed CAD patients but also with better psychosocial status and mental well-being. Possible mechanisms of this effect are discussed.

Abstract
OBJECTIVE Coffee is one of the most widely consumed beverages worldwide. Aim of this study was to investigate short-term effects of espresso coffee on heart rate variability (HRV), a marker of vagal activity, in healthy habitual and non-habitual coffee consumers. METHODS Seventy-seven healthy subjects (38 habitual and 39 non-habitual coffee consumers, 74% women, mean age 26.97 ± 6.88 years) took part in three laboratory sessions in a randomized order. In condition 1, subjects consumed espresso; in condition 2, subjects consumed decaffeinated espresso; and in condition 3, subjects consumed warm water. HRV and blood pressure were assessed at rest before and after ingestion of the respective beverage. RESULTS HRV was significantly increased after consumption of caffeinated espresso, decaffeinated espresso, or water, indicating increased vagal activity in the course of the experiments. In the habitual coffee consumers, the increase in vagally mediated HRV was significantly lower after consumption of decaffeinated espresso compared to caffeinated espresso. Increases of systolic blood pressure were only found in the non-habitual consumers. CONCLUSION We found no evidence for specific short-term effects of caffeinated espresso on vagal activity in healthy subjects. Instead, consumption of decaffeinated espresso inhibited vagal activity in habitual consumers. This may be explained by an attempt of the organism to establish a sympathovagal equilibrium comparable to that after caffeine consumption. In the absence of caffeine-induced sympathetic activation, this may have been achieved by relative vagal withdrawal.

Autonomic effects of suggestive placebo interventions to increase or decrease blood pressure: a randomized controlled trial in healthy subjects. J Psychosom Res 2013; 75:32-5.

Abstract
OBJECTIVE Placebo effects on pain and other subjective parameters are well-established, but the evidence for placebo effects on autonomic functions is scarce. Our randomized-controlled trial aimed to investigate autonomic responses after a suggestive placebo intervention intended to increase or decrease blood pressure (BP). METHODS 92 healthy subjects inhaled a placebo spray with the prior suggestion that it contained an effective drug to either increase or decrease BP, or the information that a placebo was administered (controls). BP, heart rate, stroke volume, peripheral resistance, heart rate variability and skin conductance level were monitored 30min before and after placebo administration. The expected and the subjectively perceived drug effect were measured by means of visual analog scales. RESULTS We found no statistically significant differences between the groups with respect to BP, heart rate, stroke volume, total peripheral resistance and heart rate variability responses to the verbal suggestions. Skin conductance response was more pronounced in the BP decrease group compared with controls (p=0.04), but this finding might be due to chance, given the multiple tests. Within the total study sample, BP, total peripheral resistance, low frequency power of heart rate variability and skin conductance were significantly higher after the placebo spray independent of the associated suggestions. Subjects in the BP increase and BP decrease condition had higher ratings of the expected and the subjectively perceived drug effect compared with controls (all p<0.05). CONCLUSION We found no evidence that specific verbal suggestions during placebo interventions affect BP in healthy subjects.

Abstract
RATIONALE Animal studies suggest that the pineal hormone melatonin influences basal stress hormone levels and dampens hormone reactivity to stress. OBJECTIVES We investigated whether melatonin also has a suppressive effect on stress-induced catecholamine and cortisol release in humans. As stress hormones affect memory processing, we further examined a possible accompanying modulation of memory function. MATERIALS AND METHODS Fifty healthy young men received a single oral dose of either 3 mg melatonin (n = 27) or placebo medication (n = 23). One hour later, they were exposed to a standardized psychosocial laboratory stressor (Trier Social Stress Test). During stress, subjects encoded objects distributed in the test room, for which memory was assessed a day later ("memory encoding under stress"). Fifteen minutes following stress, memory retrieval for words learnt the day before was tested ("memory retrieval after stress"). Plasma epinephrine and norepinephrine levels, salivary free cortisol levels and psychological responses (attention, wakefulness) were repeatedly measured before and after stress exposure. RESULTS Melatonin specifically enhanced recognition memory accuracy of objects encoded under stress (p < 0.001). In contrast, 15 min after stress, when cortisol levels were highest, retrieval of memories acquired the day before was not influenced by melatonin. Moreover, melatonin did not influence stress-induced elevation of catecholamine and cortisol levels which in turn did not correlate with the effects of melatonin on memory. CONCLUSIONS The findings point to a primary action of melatonin on central nervous stimulus processing under conditions of stress and possibly on memory consolidation and exclude any substantial suppressive action of the substance on hormonal stress responses.

Abstract
Blood pressure reactivity to mental stress in hypertensives is much higher than in normotensives. The authors' aim in this study was to examine whether different cardiovascular responses can be induced by various stimuli in hypertensive subgroups. The authors matched 10 essential hypertensives (EHs), 10 renal hypertensives (RHs), and 10 normotensives (Ns) according to age and gender examined them during an emotion-stimulating interview, and measured blood pressure (BP) and heart rate (HR) during the phases of the interview. They observed differences in BP reactivity between EHs/RHs and Ns under some stimuli but not between EHs and RHs, as well as a marked difference in the product of systolic BP (SBP) and HR between both hypertensive groups in the anger/rage phase (p = .028) and the baseline 2 (p = .02). This shows a higher cardiovascular activation under mental stress and a lower recovery in EHs and more sensitivity to perturbation or higher central tension compared with RHs.

Abstract
Influences of psychological stress on the acquired immune system have not consequently been investigated. We found acute psychological stress to cause an increase in CD56+ and CCR5+ effector T cells in the peripheral blood of healthy human subjects (N=22), while skin-homing CLA+ T cells decreased. At the same time, we observed a stress-induced decrease in CD45RA+/CCR7+ naive and CD45RA-/CCR7+ central memory T cells, while CD45RA-/CCR7- effector memory and CD45RA+/CCR7- terminally differentiated T cells increased. This T cell redistribution translated into an increase in T cells expressing perforin/granzyme B and in Epstein-Barr virus-specific, cytomegalovirus-specific and influenza virus-specific CD8+ T cells. Thus, acute stress seems to promote the retention of less mature T cells within lymphoid tissue or skin while effector-type T cells are mobilized into the blood in order to be able to rapidly migrate into peripheral tissues.

Abstract
The diagnosis of cancer threatens the psychological and bodily integrity. Based on this assumption, we aimed to explore how newly diagnosed patients cope with special regard to the body image (BI). In total, 40 patients (32 haematological malignancies) were assessed by questionnaires on mood, complaints, self-regulation and quality of life (QOL). The BI was assessed by the 'Body Grid' which reveals the constructs patients choose to characterize the body. The constructs were categorized using a model of six predefined categories comprising: emotion, control, activity, strength, function and appearance. Tinnitus sufferers and medical students served as comparison groups. Cancer patients showed significantly more anxious depression and a significantly lower QOL than controls. Their BI was restricted, focusing the functional status of body organs (e.g. opposing healthy vs. ill organs) as well as emotional aspects (e.g. trust vs. fear). The data convey fundamental psychological distress in newly diagnosed cancer patients. Restriction of BI and use of functional constructs may help to buffer the threat to body integrity. The emotional constructs reflect the existential impact. The data give a clear indication for the need for early psychosocial support which should aim at stabilizing the psychological and bodily integrity of the patient.

Abstract
1. The Ca(2+) sensitivity of smooth muscle contractility is modulated via regulation of phosphatase activity. Protein phosphatase inhibitor-1 (I-1) is the classic type-1 phosphatase inhibitor, but its presence and role in cAMP-dependent protein kinase (PKA) modulation of smooth muscle is unclear. To address the relevance of I-1 in vivo, we investigated smooth muscle function in a mouse model lacking the I-1 protein (I-1((-/-)) mice). 2. Significant amounts of I-1 protein were detected in the wild-type (WT) mouse aorta and could be phosphorylated by PKA, as indicated by (32)P-labelled aortic extracts from WT mice. 3. Despite the significant presence of I-1 in WT aorta, phenylephrine and KCl concentration- isometric force relations in the presence or absence of the PKA pathway activator isoproterenol (isoprenaline) were unchanged compared to I-1((-/-)) aorta. cGMP-dependent protein kinase (PKG) relaxation pathways were also not different. Consistent with these findings, dephosphorylation rates of the 20 kDa myosin light chains (MLC(20)), measured in aortic extracts, were nearly identical between WT and I-1((-/-)) mice. 4. In the portal vein, I-1 protein ablation was associated with a significant (P < 0.05) rightward shift in the EC(50) of isoproterenol relaxation (EC(50) = 10.4 +/- 1.4 nM) compared to the WT value (EC(50) = 3.5 +/- 0.2 nM). Contraction in response to acetylcholine as well as Ca(2+) sensitivity were similar between WT and I-1((-/-)) aorta. 5. Despite the prevalence of I-1 and its activation by PKA in the aorta, I-1 does not appear to play a significant role in contractile or relaxant responses to any pharmacomechanical or electromechanical agonists used. I-1 may play a role as a fine-tuning mechanism involved in regulating portal vein responsiveness to beta-adrenergic agonists.

Abstract
Insulin-like growth factor I (IGF-I) has been postulated to function as a vasodilator. We explored the vasoactive effects of chronic elevations of arterial IGF-I levels in SMP8-IGF-I mice, in which IGF-I is overexpressed in smooth muscle (SM) by means of a SM alpha-actin promoter. Denuded aortas from SMP8-IGF-I mice generated increased force in response to KCl or phenylephrine and had greater sensitivity to KCl depolarization. This is not due to desensitization of a SM NO pathway, as pretreatment with n-omega-nitro-L-arginine affected both wild-type and SMP8-IGF-I aortas to a similar degree. The increased contractility ex vivo is not associated with changes in heart rate or blood pressure. Total smooth muscle myosin heavy chain (SMHC) messenger RNA (mRNA) was greater in SMP8-IGF-I aortas, with preferential expression of SMHC-A. Reciprocal effects on contractility and SMHC mRNA were observed in SMP8-IGFBP-4 animals, in which IGF-binding protein-4 was overexpressed through the same promoter. Also, SM alpha-actin mRNA was increased in the aortas from SMP8-IGF-I mice. In summary, chronic arterial overexpression of IGF-I is associated with increased contractility. These effects differ from those seen after acute exposure to the growth factor and may relate to IGF-mediated changes in expression and relative isoform abundance of critical contractile proteins.

Abstract
PTH-related peptide is produced in vascular smooth muscle and is believed to participate in the local control of vascular tone. The recent identification of mid-region PTHrP peptides, as well as the discovery of multiple receptors in blood vessels, raises new questions concerning the mechanisms by which PTHrP relaxes the vasculature. In this study, we examined these mechanisms in two vascular beds of the mouse. PTHrP-(1-34) and PTH-(1-34), but not PTHrP-(38-64) or PTHrP-(38-94), caused concentration-dependent relaxation of pre-contracted aortas and reduced the spontaneous phasic activity of the portal vein. PTHrP and PTH-induced aortic relaxations were largely endothelium dependent, whereas an intact endothelium was not necessary for maximal portal vein relaxation. The endothelium-dependent component of PTHrP and PTH-induced aortic relaxations were unaffected by pretreatment with either L-NNA or indomethacin but were abolished by pretreatment with tetrabutyl ammonium. These results demonstrate that the N-terminal portions of PTHrP and PTH are required for their vasorelaxant activity in the mouse. In addition, maximal relaxant activity of PTHrP and PTH in murine aorta is dependent on the endothelium, which appears to involve the generation of an endothelium-derived hyperpolarizing factor.
