Abstract. Controlled studies and clinical observations can elucidate the influence of music on blood pressure and heart rate, but do not explain underlying mechanisms. Clarification of contradictory scientific results requires an understanding of corresponding psycho-neuroendocrinological processes and is also indispensable to patient-centered cardiac music therapy interventions. The paper is intended to complement the thematic issue on music therapy in cardiology (MTK 25 (1), 2014). To identify neural and neuroendocrine modules linking auditory and neurocardiac systems. This should facilitate a diagnosis-specific application of music for cardiac patients. Review of empirical, neuroanatomic, and interdisciplinary medical findings about cerebral music processing. Meta-synthesis and construction of a theoretical framework that explains the impact of music on blood pressure and heart rate. Music-induced cardiac processes can be elucidated by neural and neuroendocrine modules linking auditory processing areas and neurocardiac centers. Efferent projections from the auditory pathway as well as top–down projections arising from the auditory cortex form specific functional circuitries. Overlapping and interacting projections from cortical and subcortical regions to associative processing organs (e. g., the insular cortex) integrate both physiologically and cognitively processed sound factors (i. e., the dualistic model). Via corresponding modules the auditory system is indirectly linked to hypothalamic nuclei, influencing the hypothalamic–pituitary–adrenal axis as well as vasopressin- and oxytocin-related processes. Connections with the locus coeruleus refer to noradrenergic sound–heart regulation. Physiological mechanisms interacting with individual musical experiences require the synopsis of evidence-based findings, neuroendocrinological explanations, and differential psychological profiles for reliable treatment planning.

Background:Music therapy is based on ancient cross-cultural beliefs that music can have a “healing” effect on mind and body. Research determined that listening to music can increase comfort and relaxation, relieve pain, lower distress, reduce anxiety, improve positive emotions and mood, and decrease psychological symptoms. Music therapy has been used greatly in various medical procedures to reduce associated anxiety and pain. Patients have a high level of anxiety when they are in the hospital, this is the case of patients with rheumatic diseases who consult regularly to have intravenous infusion of biological therapies.Objectives:The purpose of this study was to examine the effectiveness of music therapy on pain, anxiety, and vital signs among patients with chronic inflammatory rheumatic diseases during intravenous infusion of biological drugs.Methods:Fifty patients were divided into two groups: The experimental group G1 (n=25) received drug infusion while lestening to soft music (30 minutes); and the control group G2 (n=25) received only drug infusion. Measures include pain, anxiety, vital signs (blood pressure, heart rate and respiratory rate). The pain was measured using visual analogic scale (VAS). The state-trait anxiety inventory (STAI) was used for measuring anxiety, low anxiety ranges from 20 to 39, the moderate anxiety ranges from 40 to 59, and high anxiety ranges from 60 to 80. Vital signs (systolic blood pressure [SBP], diastolic blood pressure [DBP], heart rate [HR], and respiratory rate [RR]) were measured before, during and immediately after the infusion.Statistical package for social sciences (SPSS) was used for analysis.Results:The mean age in G1 was 44.45 years (26-72) with a sex ratio (M/F) of 0.8. Including the 25 patients, 12 had rheumatoid arthritis, 10 had ankylosing spondylitis and 3 had psoriatic arthritis. The mean disease duration was 8 years. In G2, the mean age was 46 years (25-70) with a sex ratio (M/F) of 0.75, 12 had rheumatoid arthritis, 11 had ankylosing spondylitis and 2 had psoriatic arthritis. The mean disease duration was 7.5 years. The biological drugs used were: Infliximab in 30 cases, Tocilizumab in 12 cases and Rituximab in 8 cases.Before the infusion, the patients of experimental group had a mean VAS of 5/10±3, a mean STAI of 50.62±6.01, a mean SBP of 13.6 cmHg±1.4, a mean DBP of 8.6 cmHg±1, a mean HR of 85±10 and a mean RR of 18±3. While in control group the mean VAS was 5.5±2, the mean STAI was 50.89±5.5, the mean SBP was 13.4±1.2, the mean DBP was 8.8±1.1, the mean HR was 82±8 and the mean RR was 19±2.During the infusion and after music intervention in G1, the mean STAI became 38.35±5 in G1 versus 46.7±5.2 in G2 (p value=0.022), the mean SBP became 12.1±0.5 in G1 versus 13±1 in G2 (p=0.035), the mean DBP became 8.1±0.8 in G1 versus 8.4±0.9 in G2 (p=0.4), the mean HR became 76±9 in G1 versus 78±7 in G2 (p=0.04) and the mean RR became 17.3±2.1 in G1 versus 18.2±1.7 in G2 (p=0.39).This study found a statistically significant decrease in anxiety, systolic blood pressure and heart rate in patients receiving music interventions during biological therapies infusion, but no significant difference were identified in diastolic blood pressure and respiratory rate.Conclusion:The findings provide further evidence to support the use of music therapy to reduce anxiety, and lower systolic blood pressure and heart rate in patients with rheumatic disease during biological therapies infusion.References:[1] Lin, C., Hwang, S., Jiang, P., & Hsiung, N.

The Impact

OSA (obstructive sleep apnoea) stimulates sympathetic nervous activity and elevates resting HR (heart rate) and BP (blood pressure). In the present study in a cohort of 309 untreated OSA patients, the resting HR and BP during the daytime were correlated with AHI (apnoea/hypopnea index) and compared with patients with R389R (n=162), R389G (n=125) and G389G (n=22) genotypes of the β1-adrenoreceptor R389G polymorphism. We analysed the impact of the genotype on the decline of HR and BP in a subgroup of 148 patients (R389R, n=86; R389G, n=54; G389G, n=8) during a 6-month follow-up period under CPAP (continuous positive airway pressure) therapy during which cardiovascular medication remained unchanged. In untreated OSA patients, we found an independent relationship between AHI and resting HR (β=0.096, P<0.001), systolic BP (β=0.09, P=0.021) and diastolic BP (β=0.059, P=0.016). The resting HR/BP, however, did not differ among carriers with the R389R, R389G and G389G genotypes. CPAP therapy significantly reduced HR [−2.5 (−1.1 to −4.0) beats/min; values are mean difference (95% confidence intervals)] and diastolic BP [−3.2 (−1.5 to −5.0) mmHg]. The decline in HR was more significantly pronounced in the R389R group compared with the Gly389 carriers [−4.1 (−2.3 to −5.9) beats/min (P<0.001) compared with −0.2 (2.1 to −2.6) beats/min (P=0.854) respectively; Student's t test between groups, P=0.008]. Diastolic BP was decreased significantly (P<0.001) only in Gly389 carriers (R389G or G389G) compared with R389R carriers [−5.0 (−2.3 to −7.6) mmHg compared with −2.0 (0.4 to −4.3) mmHg respectively]. ANOVA revealed a significant difference (P=0.023) in HR reduction between the three genotypes [−4.1 (±8.4) beats/min for R389R, −0.5 (±9.3) beats/min for R389G and +1.9 (±7.2) beats/min for G389G]. In conclusion, although the R389G polymorphism of the β1-adrenoceptor gene did not influence resting HR or BP in untreated OSA patients, it may modify the beneficial effects of CPAP therapy on these parameters.

Preparation of patients mental before to surgery is needed. If patients experience severe anxiety and panic operating plan will be delayed, it will allow a greater risk of infection. From various research show that music has a strong influence on health, especially in calming the mind, reduce physical tension and create a relaxed state, if the patient in a relaxed state is expected to affect physiological responses. The purpose of this study was to determine the effect of classical music therapy on physiological responses in patients who underwent orthopedic praoperatif anxiety. The study design is pre-experiment with a sample of 30 people using purposive sampling. Music therapy is given for ± 30 minutes. The analysis used were Paired Sample T Test and Wilcoxon. Obtained mean systolic blood pressure was 120.2 mmHg before therapy, after therapy 119.6 mmHg, p value = 0.227. Mean diastolic blood pressure before treatment was 74.1 mmHg, 73.2 mmHg after therapy is, p value = 0.133. Mean heart rate before treatment was 81.8 x / min, after therapy was 79 x / minute, p value = 0.005. Median respiratory frequency before treatment was 23 x / minute, after the therapy is 21 x / minute, p value = 0.001. This shows the classical music therapy has an influence on heart rate and respiratory frequency in patients who underwent orthopedic praoperatif anxiety. Researchers recommend the use of classical music therapy with a frequency of 2 to 3 times a day before patients undergo surgery in order to obtain an optimal relaxation effects.

AimsTo establish whether physical health monitoring for CYP on ADHD medication is according to NICE guidance (2018).To determine the impact of COVID-19 pandemic restrictions on physical health monitoring for CYP on ADHD medication.Attention deficit hyperactivity disorder (ADHD) is a common neurodevelopmental disorder, characterised by a persistent pattern of inattention and/or hyperactivity-impulsivity, directly impacting on academic, occupational, or social functioning. It affects between 1-5% of children and young people (CYP) most often presenting in early-mid childhood.Pharmacological treatment can be considered in CYP if certain criteria are met, where licensed medications include methylphenidate, dexamfetamine, lisdexamfetamine, atomoxetine and guanfacine. Stimulant and non-stimulant medications require frequent physical health monitoring due to their side effects including an increase in blood pressure and/or heart rate, loss of appetite, growth restriction and tics.MethodStandards and criteria were derived from the NICE guidance (2018), whilst local trust policies were reviewed, demonstrating discrepancies. Standards were expected to be met for 100% of patients.Electronic patient records were reviewed retrospectively from a representative cohort of CYP reviewed by clinicians in a community CAMHS service during March-November 2020. Data were entered manually into a spreadsheet for evaluation.ResultA total of 27 CYP records were reviewed, average age 13yo, on a range of stimulant/non-stimulant preparations.5 (19%) had height checked every 6 months, with 4 delayed to 7-8 months.For those >10yo, only 5 (19%) had weight checked every 6 months.Only 2 (7%) had their height and weight plotted on a growth chart and reviewed by the healthcare professional responsible for treatment.Just 4 (15%) had heart rate and blood pressure recorded before and after each dose change, whilst similarly only 4 (not the same) had these parameters recorded every 6 months.17 patients were reviewed by telephone/video call, where 5 patients provided physical health parameters (measured at home).ConclusionAcross all parameters, standards are not being met for the required physical health monitoring for CYP on ADHD medication.The COVID-19 pandemic has significantly changed the working conditions for community teams, impacting face to face reviews, creating challenges for physical health monitoring.Our ongoing implementations for change include the use of a proforma for physical health measurements, improving psychoeducation for families, exploring potential barriers with senior colleagues and collaborating with pharmacy colleagues to update local guidelines in accordance with the latest NICE recommendations. We aim to re-audit in June 2021.

The Impact

Patients with metabolic syndrome are at higher risk for cardiac arrest (CA), and also have worse neurologic outcome after CA related to their comorbidities (e.g., Type 2 Diabetes Mellitus [T2DM]). Using Zucker Diabetic Fatty (ZDF) rats as a new and relevant model with common comorbidities for CA and cardiopulmonary resuscitation (CPR), we hypothesized that T2DM is associated with a lower chance for return of spontaneous circulation (ROSC) and/or a worse outcome regarding heart function after asphyxial CA compared to their lean littermates. Two groups of rats (8 ZDF, 7 lean) were monitored for 37±2 weeks. The rats were anesthetized and intubated; heart rate was monitored by subcutaneous ECG needles. Femoral artery and vein were cannulated for continuous blood pressure measurement and delivery of fluids and medications, respectively. Before ventilation was stopped to initiate asphyxial CA, rocuronium was given. After 8 minutes of CA, ventilation was re-initiated with FiO 2 1.0, epinephrine and sodium-bicarbonate were administered, and pneumatic chest compression were started with 200 compressions per minute. Chest compressions were stopped when a systolic blood pressure of 120 mmHg was achieved. During 4 hours of observation, vital parameters were closely monitored, blood gases were measured, and ejection fraction (EF %) was assessed with ultrasound. Data are mean ± SD. Statistics: Unpaired student’s t-test (two-tailed), α.05. At baseline, ZDF rats showed significantly higher blood glucose levels (504±52 vs 174±14 mg/dl) compared to their lean littermates. All ZDF and lean rats achieved ROSC, and measurements taken directly after ROSC and after the first hour showed no relevant differences. After four hours, there was no difference in heart rate between ZDF and lean rats. However, diabetic rats had a significantly higher mean arterial blood pressure (142±24vs. 107±19 mmHg) and ejection fraction (42±16%vs 20±8%) compared to their lean littermates. The hypothesis that ROSC-rate in diabetic rats would be lower could not be proven. Conversely, the ZDF rats showed a significantly higher blood pressure related to an increased EF%. Further analysis in this study will focus on the impact of T2DM on cardiac and neurological ischemia-reperfusion injury.

The Impact

Endothelial dysfunction increases cardiovascular disease risk in chronic kidney disease (CKD). This study investigates whether VDR activation affects endothelial function in CKD. The 5/6 nephrectomized (NX) rats with experimental chronic renal insufficiency were treated with or without paricalcitol, a VDR activator. Thoracic aortic rings were precontracted with phenylephrine and then treated with acetylcholine or sodium nitroprusside. Uremia significantly affected aortic relaxation (% in NX rats versus % in SHAM at 30 M acetylcholine). The endothelial-dependent relaxation was improved to –%, –%, and –% in NX rats treated with paricalcitol at 0.021, 0.042, and 0.083 g/kg for two weeks, respectively, while paricalcitol at 0.042 g/kg did not affect blood pressure and heart rate. Parathyroid hormone (PTH) suppression alone did not improve endothelial function since cinacalcet suppressed PTH without affecting endothelial-dependent vasorelaxation. N-omega-nitro-L-arginine methyl ester completely abolished the effect of paricalcitol on improving endothelial function. These results demonstrate that VDR activation improves endothelial function in CKD.

Purpose: To evaluate the effects of passive music therapy on anxiety and vital signs among lung cancer patients at their first peripherally inserted central catheter placement procedure in China. Methods: A randomized controlled clinical trial was conducted in the cancer center of a hospital in Chengdu from May to December 2017. A total of 304 lung cancer patients who met the inclusion and exclusion criteria were recruited and randomly assigned to experimental ( n = 152) and control ( n = 152) group, respectively. The control group only received standard care, while the experimental group received standard care and passive music therapy during peripherally inserted central catheter placement (30–45 min) and after catheterization, until discharged from the hospital (twice a day, 30 min once). Measures include anxiety and vital signs (blood pressure, heart rate, and respiratory rate). Results: Repetitive measurement and analysis of variance showed that the patients in experimental group had a statistically significant decrease in anxiety, diastolic blood pressure, and heart rate over time compared to the control group, but no significant difference was identified in systolic blood pressure and respiratory rate. Conclusion: Passive music therapy can efficiently relieve the anxiety of lung cancer patients during peripherally inserted central catheter placement. It also can lower the patient’s diastolic blood pressure and slow down the heart rate. So, music therapy benefits patients with peripherally inserted central catheter.

Abstract Introduction: Earlier this year, heparin was found to be contaminated with a non-heparin sulfated polymer identified as oversulfated chondroitin sulfate (OSCS). The presence of this contaminant was associated with severe adverse reactions such as hypotension and anaphylaxis, leading to death in some patients. Some batches of a widely used low-molecular heparin, enoxaparin, also contained OSCS. However, the amount of this contaminant was much lower (less than 5%) in the low-molecular weight heparin batches compared to unfractionated heparin where the amount of the contaminant was up to 30%. Owing to the sizeable number of syringes in Europe that contained the low level of OSCS and the absence of any serious adverse events, the European Medicines Equivalence Agency (EMEA) allowed the qualified use of the subcutaneous administration of the contaminated enoxaparin to ensure access to this essential medication. Despite this, no studies on the anti-thrombotic and bleeding effects or basic physiologic parameters have been reported. To address the bioequivalence of enoxaparin and its contaminated version, studies were undertaken in established animal models of bleeding and thrombosis. Materials & Methods: Contaminant-free enoxaparin (CFE) and one of the commercially available contaminated enoxaparin (CCE) batches were compared at an equivalent subcutaneous dosage of 2.5 mg/kg in a jugular vein clamping model of thrombosis (n=6/group). A separate group comprised of saline control animals served as control. Blood pressure and heart rate measurements were made at 90 minutes after drug administration, followed by jugular vein clamping model at 120 minutes after drug administration. After the completion of the jugular vein clamping model, blood samples were collected via cardiac puncture for ex-vivo monitoring of anti-coagulant and anti-protease effects. Results: No differences in the blood pressure and heart rate were observed between the two groups. The anti-thrombotic effects of both the CCE and CFE were measured by jugular vein clamping model. In comparison to the saline treated group (3.5 ± 0.5 clampings), both the CCE and CFE treated animals required a significantly higher number of clampings to induce thrombosis (4.8 ± 0.7 and 5.0 ± 0.6, respectively; p = 0.001 vs. saline; p=0.658 CFE vs. CCE). The ex-vivo analysis of whole blood aPTT revealed a slight elevation in both of the enoxaparin-treated groups in comparison to saline control. (CFE: 36.8 ± 18.6 sec; CCE: 30.5 ± 10.9 sec vs. saline: 26.7 ± 3.9 sec). The anti-Xa effects in plasma were significantly higher with the CFE (84.4 ± 1.5% inhibition) compared to that observed with the CCE (80.5 ± 2.9 % inhibition; p=0.026) while the anti-IIa levels were comparable in the two groups (37.1 ± 22.0 and 30.6 ± 17.9 % inhibition). Ex-vivo analysis of plasma samples from the control group did not reveal any anti-protease or anti-coagulant activity. Discussion: These results demonstrate that small amounts of OSCS (less than 5%) in enoxaparin do not impact its anti-thrombotic effects when administered subcutaneously. Since OSCS exhibits only anti-IIa activity and does not have any anti-Xa effects, the observed anti-Xa activity of the CCE was less than that of CFE. Other plasmatic anti-coagulant and anti-protease activities were not altered by the presence of OSCS. Since OSCS is highly charged it is likely that upon subcutaneous administration it is not absorbed. This observation is supported by the fact that the anti-Xa and IIa ratios of the samples collected after jugular vein clamping are approximately equal. Thus, the anti-thrombotic and pharmacodynamic effects of the two versions of enoxaparin are identical. The impact of repeated administration of contaminated enoxaparins and long-term pharmacodynamic and immunogenic effects need to be further explored.

Dexmedetomidine Infusion

Aim. This study aimed to evaluate the pharmacodynamics of dexmedetomidine in elderly cardiac patients.Material and Methods. Twelve patients of 60 years or older and need for analgesia after surgery or as a result of critical health conditions were included into our study. Dexmedetomidine was administered intravenously as a continuous infusion without the initial dose. At the beginning the infusion was started at the rate of 0.7 μg/kg/h and then it was continued in the range of 0.17–1.39 μg/kg/h according to desired level of sedation. Information about heart rate, systolic, diastolic and mean arterial blood pressure, bispectral index and cardiac index were collected a few minutes before, during and in 12 hours after infusion of dexmedetomidine.Results. The hemodynamic data as well as BIS level were collected from 12 patients. The duration of dexmedetomidine infusion was less than 9 hours. For each patient the reduction in blood pressure and heart rate compared to the value before dexmedetomidine infusion was observed. We did not observe bradycardia in any patient. Appropriate sedation level was achieved using only dexmedetomidine and ranged from 60 to 80. In only 2 cases it was necessary to give a single dose of another sedative.Conclusions. To conclude, in the patients’ population involved in the study, which included older cardiac patients dexmedetomidne has been shown as a sedative agent which enabled to achieve desire level of sedation in the recommended ranges without episodes of bradycardia, however hypotension events were noted.
