Exhaustion, immuno-inflammation, and pathogen burden after cardiac surgery: an exploratory study

Psychosomatic syndromes are associated with IL-6 pro-inflammatory cytokine in heart failure patients

Psychosomatic syndromes have emerged as an important source of comorbidity in cardiac patients and have been associated with increased risk for adverse outcomes in patients with heart failure (HF). Understanding of the mechanisms underlying this connection is limited, however immune activity represents a possible pathway. While there have been numerous studies connecting immune activity to psychosomatic psychopathology, there is a lack of research on patients with HF. We examined forty-one consecutive outpatients affected by HF. We assessed psychosomatic psychopathology using the Diagnostic Criteria for Psychosomatic Research (DCPR) and the Patient Health Questionnaire-15 (PHQ-15). The Psychosocial Index (PSI) was used for assessing stress and psychosocial dimensions. Depression was evaluated with Beck Depression Inventory-II (BDI-II). Circulating levels of proinflammatory cytokines IL-6 and TNF-alpha were ascertained. Univariate and multivariable regression models were used to test for associations between inflammatory cytokines and psychosomatic psychopathology (i.e., DCPR syndromes, PHQ-15) and psychological dimensions (i.e., BDI-II, PSI). A significant positive correlation was found between IL-6 levels and psychosomatic psychopathology even when controlling for any confounding variables (i.e., Body-mass index (BMI), New York Heart Association (NYHA) class, smoking habits, alcohol consumption, statin use, aspirin use, beta blockers use, age, and gender). In contrast, the associations between TNF-alpha levels were non-significant. These findings can contribute to research in support of a psychoneuroimmune connection between psychosomatic psychopathology and HF. Findings also suggest the possibility that elevated IL-6 levels are more relevant for the pathogenesis of psychosomatic syndromes than for depression in patients with HF.

Development of an internet-delivered program and platform for the treatment of depression and anxiety in patients with ischemic heart disease in eMindYourHeart

To design and evaluate a mental health treatment program and internet-based delivery platform for patients with ischemic heart disease (IHD) attending cardiac rehabilitation with the aim of reducing the risks associated with anxiety and/or depression. Patients diagnosed with IHD and comorbid anxiety and/or depression. Participatory design of treatment program and internet platform through staged inclusion of participants in two groups. Group 1 was enrolled as co-researchers with prolonged engagement in the project. Group 2 participated only in the pilot evaluation workshop. Three patients were included in Group 1, two patients in Group 2. Inclusion of patients proved challenging, but the extended collaboration with co-researchers yielded valuable circumstantial insight and resulted in the design of a novel nine-module treatment program. Additionally, the inclusion of two participant groups helped shape the development of an internet platform based on an open-source content management system. Our grouped participation method contributes with several recommendations and reflections of advantages of this approach. Collaboration with co-researchers helped us gain a deeper understanding of the impact of language on self-perception and potential stigma. Prolonged participation led to a higher level of trust and familiarity, which enabled uncovering of issues otherwise hidden.

Effects of foot massage and patient education in patients undergoing coronary artery bypass graft surgery: A randomized controlled trial

BACKGROUND

Anxiety, pain, and fatigue are common postoperative problems that disturb the recovery and quality of life in patients undergoing coronary artery bypass graft (CABG) surgery. These postoperative problems are associated with prolonged recovery and decreased quality of life. This study was aimed at evaluating the combined effects of foot massage and patient education on anxiety, fatigue, pain, self-efficacy, and quality of life in patients undergoing CABG surgery.

MATERIAL AND METHODS

In this randomized controlled trial (RCT), 130 participants were randomly allocated to experimental (n = 65) and control (n = 65) groups. The experimental group received a combination of foot massage and patient education as interventions and the control group received usual care of the hospital.

RESULTS

The experimental group had a significant decrease in anxiety (p = 0.001), fatigue (p = 0.001), pain (p = 0.001), and increased self-efficacy (p = 0.001) and quality of life (p = 0.001).

CONCLUSION

The combined form of foot massage and patient education is effective in decreasing anxiety, fatigue, pain, and increasing self-efficacy and the quality of life. These interventions will support the recovery of patients and reduce their suffering.

Reporter Cell Assessment of TLR4-Induced NF-κB Responses to Cell-Free Hemoglobin and the Influence of Biliverdin

Hemoglobin (Hb) released during red blood cell lysis can initiate TLR4-dependent signaling and trigger NF-κB activation in surrounding cells. Observations of chronic bleeding in various cancers leads us to hypothesize that Hb and Hb degradation products released from lysed RBC near cancer nests might modulate local TLR4-positive cells. We addressed the hypothesis in vitro by measuring Hb- and biliverdin (Bv)-induced NF-κB signaling in an engineered human TLR4 reporter cell model (HEK-Blue^TM hTLR4). Therein, TLR4 stimulation was assessed by measuring NF-κB-dependent secreted alkaline phosphatase (SEAP). hTLR4 reporter cells incubated with 8 ηM lipopolysaccharide (LPS) or 20-40 μM fungal mannoprotein (FM) produced significant amounts of SEAP. hTLR4 reporter cells also produced SEAP in response to human, but not porcine or bovine, Hb. HEK-Blue Null2^TM reporter cells lacking TLR4 did not respond to LPS, FM, or Hb. Bv was non-stimulatory in reporter cells. When Bv was added to Hb-stimulated reporter cells, SEAP production was reduced by 95%, but when Bv was applied during LPS and FM stimulation, SEAP production was reduced by 33% and 27%, respectively. In conclusion, Hb initiated NF-κB signaling that was dependent upon TLR4 expression and that Bv can act as a TLR4 antagonist. Moreover, this study suggests that hemorrhage and extravascular hemolysis could provide competitive Hb and Bv signaling to nearby cells expressing TLR4, and that this process could modulate NF-κB signaling in TLR4-positive cancer cells and cancer-infiltrating leukocytes.

Selecting symptom instruments for cardiovascular populations

The purpose of this review is to provide a guide for researchers and clinicians in selecting an instrument to measure four commonly occurring symptoms (dyspnea, chest pain, palpitations, and fatigue) in cardiac populations (acute coronary syndrome, heart failure, arrhythmia/atrial fibrillation, and angina, or patients undergoing cardiac interventions). An integrative review of the literature was conducted. A total of 102 studies summarizing information on 36 different instruments are reported in this integrative review. The majority of the instruments measured multiple symptoms and were used for one population. A majority of the symptom measures were disease-specific and were multi-dimensional. This review summarizes the psychometrics and defining characteristics of instruments to measure the four commonly occurring symptoms in cardiac populations. Simple, psychometrically strong instruments do exist and should be considered for use; however, there is less evidence of responsiveness to change over time for the majority of instruments.
