Depression and Physical Inactivity as Confounding the Effect of Obesity on Atrial Fibrillation

Exploring Depressive Symptoms and Anxiety Among Patients With Atrial Fibrillation and/or Flutter at the Time of Cardioversion or Ablation

BACKGROUND

Depression and anxiety in patients with atrial fibrillation (AF) and/or atrial flutter may influence the effectiveness of cardioversion and ablation. There is a lack of knowledge related to depressive symptoms and anxiety at the time of these procedures.

OBJECTIVE

We aimed to describe the prevalence and explore potential covariates of depressive symptoms and anxiety in patients with AF at the time of cardioversion or ablation. We further explored the influence of depressive symptoms and anxiety on quality of life at the time of procedure and 6-month AF recurrence.

METHODS

Depressive symptoms, anxiety, and quality of life were collected at the time of cardioversion or ablation using the Patient Health Questionnaire-9, State-Trait Anxiety Inventory, and Atrial Fibrillation Effect on Quality of Life questionnaire. Presence of AF recurrence within 6 months post procedure was evaluated.

RESULTS

Participants (N = 171) had a mean (SD) age of 61.20 (11.23) years and were primarily male (80.1%) and white, non-Hispanic (81.4%). Moderate to severe depressive symptoms (17.2%) and clinically significant state (30.2%) and trait (23.6%) anxiety were reported. Mood/anxiety disorder diagnosis was associated with all 3 symptoms. Atrial fibrillation symptom severity was associated with both depressive symptoms and trait anxiety. Heart failure diagnosis and digoxin use were also associated with depressive symptoms. Trends toward significance between state and trait anxiety and participant race/ethnicity as well as depressive symptoms and body mass index were observed. Study findings support associations between symptoms and quality of life, but not 6-month AF recurrence.

CONCLUSION

Depressive symptoms and anxiety are common in patients with AF. Healthcare providers should monitor patients with AF for depressive symptoms and anxiety at the time of procedures and intervene when indicated. Additional investigations on assessment, prediction, treatment, and outcome of depressive symptoms and anxiety in patients with AF are warranted.

Measurement of patient confidence in self-management of atrial fibrillation: Initial validation of the Confidence in Atrial fibriLlation Management (CALM) Scale

BACKGROUND

The patient experience of atrial fibrillation (AF) involves several daily self-care behaviors and ongoing confidence to manage their condition. Currently, no standardized self-report measure of AF patient confidence exists. The purpose of this study is to provide preliminary support for the reliability and validity of a newly developed confidence in AF management measure.

METHODS

This study provides preliminary analysis of the Confidence in Atrial FibriLlation Management (CALM) scale, which was rationally developed to measure patient confidence related to self-management of AF. The scale was provided to a sample of AF patients N = 120, (59% male) electronically through a patient education platform. Principal component analysis (PCA) and Cronbach's α were employed to provide preliminary assessment of the validity and reliability of the measure.

RESULTS

PCA identified a four-factor solution. Internal consistency of the CALM was considered excellent with Cronbach's α = .910. Additional PCA confirmed the value of a single factor solution to produce a total confidence score for improved utility and ease of clinical interpretation.

CONCLUSIONS

Initial assessment of a novel scale measuring patient confidence in managing AF provided promising reliability and validity. Patient confidence in self-management of AF may prove useful as a key marker and endpoint of the patient experience beyond QOL.

Quality of life under the COVID-19 quarantine

BACKGROUND

COVID-19 has spread rapidly throughout the world, causing thousands of illnesses and deaths. To fight this pandemic, almost all governments and health authorities have focused on prevention. In March or April, most countries' officials imposed home quarantine and lockdown measures nationwide.

PURPOSE

This study sought to assess health-related quality of life (HRQoL) and anxiety levels among people in Portugal under mandatory home quarantine due to the COVID-19 pandemic. The results were compared to the general Portuguese population's HRQoL before the COVID-19 outbreak. This research also aimed to understand the factors that can influence the respondents' HRQoL.

METHODS

A sample of Portugal's population quarantined at home (n = 904) filled in an online survey comprising the Generalized Anxiety Disorder 7-item and the EQ-5D-5L and other questions about sociodemographic characteristics, feelings, duties and activities during the quarantine. The sample was weighted to mirror the general population's gender, age and education. Descriptive analyses and correlation coefficients were used to evaluation the respondents' anxiety and HRQoL. Generalised linear models were estimated to identify determinants of HRQoL during the COVID-19 quarantine.

RESULTS

The results show that individuals quarantined at home reported higher anxiety and lower HRQoL levels and that people with more anxiety tended to have a lower HRQoL. Females and elderly individuals experienced the highest levels of anxiety and poorest HRQoL. In addition, HRQoL during the quarantine can be explained by various occupational and attitudinal variables, as well as sociodemographic variables.

CONCLUSION

Individuals' mental health should be taken into consideration during pandemics or other emergency situations. Anxiety and other factors can decrease people's HRQoL, in conjunction with the pandemic's social and economic consequences.

Obesity, self-reported symptom severity, and quality of life in people with atrial fibrillation: A community-based cross-sectional survey

BACKGROUND AND AIMS

Intentional weight loss may reduce symptom severity of atrial fibrillation (AF) in relatively young AF patients with overweight. We examined whether symptom severity and quality of life (QoL) are associated with weight status in the general population with AF.

METHODS AND RESULTS

Patients with electrocardiogram-confirmed AF completed validated questionnaires: the EuroQol 5 Dimensions QoL questionnaire and the Toronto Atrial Fibrillation Severity Scale (AFSS). The AFSS assessed the AF burden scoring on AF-related symptoms and the total AF burden measured as a combination of duration, frequency, and severity of an irregular heartbeat. Generalized liner models examined the association of body mass index (BMI) with AF severity and QoL adjusting for confounders. Between 2018 and 2019, 882 of 1901 (46%) mailed questionnaires were returned completed. Participants had a mean (SD) age of 74 (10) years old and a BMI of 27.4 (5.6) kg/m². Sixteen percent reported having never experienced an irregular heartbeat. A 5 kg/m² higher BMI was associated with a 0.65 (95%CI: 0.25 to 1.06) higher symptom score, where 3 points represent a clinically relevant change in state. A 5 kg/m² higher BMI was associated with a -1.61 (95%CI: -2.72 to -0.50) lower QoL score. The coefficient of the total AF burden for a 5 kg/m² higher BMI was 0.17 (95% CI: -0.01 to 0.68).

CONCLUSION

BMI was positively associated with symptoms and negatively associated with one of the two measures of QoL, but not with the total AF burden. However, the strength of association was small and not clinically meaningful.

Evaluation of the psychoemotional status of young adults with symptoms of temporomandibular disorders

BACKGROUND AND PURPOSE

Temporomandibular disorders (TMD) are among the most frequent pathologies of the stomatognathic system. One problem often associated with TMD is the psychoemotional status. The aim of study was to evaluate the psychoemotional status of young adults with pain symptoms associated with TMD.

MATERIAL AND METHODS

We analyzed the data of 260 volunteers. The Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) form was used to diagnose TMD. The relationships between TMD/RDC clinical diagnoses and psychoemotional status, as described by the Beck's Depression Inventory (BDI) and Perceived Stress Scale (PSS-10), were analyzed. We divide the group into four on the basis of RDC/TMD Axis I diagnosis. Group 0 included 30 students lacking TMD symptoms. Group I consisted of 30 people with myofascial pain (group IA in RDC/TMD). Group II contained 23 people with disk displacement with reduction (group IIA in RDC/TMD). Group III contained ten people (Group III diagnosis, often associated with pain).

RESULTS

We did not find statistically significant differences between the study groups. In subjects with pain (Groups I and III), we found the mean value on the BDI and PSS-10 scales to be higher than among the pain-free subjects (Groups 0 and II).

CONCLUSION

In young adults with TMD accompanied by pain, psychoemotional status should also be evaluated.

Atrial fibrillation symptom clusters and associated clinical characteristics and outcomes: A cross-sectional secondary data analysis

BACKGROUND

Symptom clusters among adults with atrial fibrillation have previously been identified but no study has examined the relationship between symptom clusters and outcomes.

AIMS

The purpose of this study was to identify atrial fibrillation-specific symptom clusters, characterize individuals with each cluster, and determine whether symptom cluster membership is associated with healthcare utilization.

METHODS

This was a cross-sectional secondary data analysis of 1501 adults from the Vanderbilt Atrial Fibrillation Registry with verified atrial fibrillation. Self-reported symptoms were measured with the University of Toronto Atrial Fibrillation Severity Scale. We used hierarchical cluster analysis (Ward's method) to identify clusters and dendrograms, pseudo F, and pseudo T-squared to determine the ideal number of clusters. Next, we used regression analysis to examine the association between cluster membership and healthcare utilization.

RESULTS

Males predominated (67%) and the average age was 58.4 years. Two symptom clusters were identified, a Weary cluster (3.7%, n=56, fatigue at rest, shortness of breath at rest, chest pain, and dizziness) and an Exertional cluster (32.7%, n=491, shortness of breath with activity and exercise intolerance). Several sociodemographic and clinical characteristics varied by symptom cluster group membership, including age, gender, atrial fibrillation type, body mass index, comorbidity status, and treatment strategy. Women were more likely to experience either cluster ( p<0.001). The Weary cluster was associated with nearly triple the rate of emergency department utilization (incident rate ratio [IRR] 2.8, p<0.001) and twice the rate of hospitalizations (IRR 1.9, p<0.001).

CONCLUSION

We identified two symptom clusters. The Weary cluster was associated with a significantly increased rate of healthcare utilization.

Atrial fibrillation symptom profiles associated with healthcare utilization: A latent class regression analysis

BACKGROUND

Symptoms drive healthcare use among adults with atrial fibrillation, but limited data are available regarding which symptoms are most problematic and which patients are most at-risk. The purpose of this study was to: (1) identify clusters of patients with similar symptom profiles, (2) characterize the individuals within each cluster, and (3) determine whether specific symptom profiles are associated with healthcare utilization.

METHODS

We conducted a cross-sectional secondary data analysis of 1,501 adults from the Vanderbilt Atrial Fibrillation Registry. Participants were recruited from Vanderbilt cardiology clinics, emergency department, and in-patient services. Subjects included in our analysis had clinically verified atrial fibrillation and a completed symptom survey. Symptom and healthcare utilization data were collected with the University of Toronto Atrial Fibrillation Severity Scale. Latent class regression analysis was used to identify symptom clusters, with clinical and demographic variables included as covariates. We used Poisson regression to examine the association between latent class membership and healthcare utilization.

RESULTS

Participants were predominantly male (67%) with a mean age of 58.4 years (±11.9). Four latent classes were evident, including an Asymptomatic cluster (N = 487, 38%), Highly Symptomatic cluster (N = 142, 11%), With Activity cluster (N = 326, 25%), and Mild Diffuse cluster (N = 336, 26%). Highly Symptomatic membership was associated with the greatest rate of emergency department visits and hospitalizations (incident rate ratio 2.4, P < 0.001).

CONCLUSIONS

Clinically meaningful atrial fibrillation symptom profiles were identified that were associated with increased rates of emergency department visits and hospitalizations.

Roux-en-Y Gastric Bypass

Background:

Roux-en-Y gastric bypass (RYGB) is considered the gold standard for gastric bypass, displaying better results for metabolic disorders than other surgical procedures over the long term. The aim of this study was to determine the effects of bariatric surgery, in particular the RYGB technique, on metabolic syndrome (MS) and other biochemical parameters implicit in the comorbid conditions associated with obesity, as well as to explore the influence of this surgical procedure on psychiatric comorbidity in the study population.

Method:

An observational retrospective cohort study based on 146 clinical records of patients having undergone RYGB between January 1, 2011, and January 1, 2014, was performed. Data related to metabolic and psychiatric comorbidity were gathered at three stages: prior to surgery and at 3 and 9 months following surgery.

Results:

There was a progressive and statistically significant reduction of all biochemical parameters analyzed at 3 and 9 months following surgery except high-density lipoprotein cholesterol, which significantly increased (beneficial) in value. These changes imply a remission of >90% for all metabolic disorders and the consequent tendency toward a reduction in prescribed pharmacological treatments, with MS found in only one subject at 9 months. There was, however, no significant reduction in pharmacological treatments for psychiatric comorbidities.

Conclusion:

Findings suggest that RYGB is an effective treatment for MS and other metabolic disorders but not for psychiatric comorbidities accompanying MS.
