Association of Psychological Characteristics and Functional Dyspepsia Treatment Outcome: A Case-Control Study

Influence of depressive disorders, stress, and personality traits on quality of life after cochlear implantation

PURPOSE

This study aimed to determine whether preoperative depressiveness, stress, and personality influence quality of life (QOL) after cochlear implant (CI) surgery.

METHODS

In this prospective study, 79 patients undergoing CI surgery were evaluated preoperatively and 12 months postoperatively. Disease-specific QOL was assessed with the Nijmegen Cochlear Implant Questionnaire (NCIQ) and general QOL with the WHOQOL-BREF. Depressiveness and stress were assessed with the Patient Health Questionnaire (PHQ-D). The Charlson Comorbidity Index (CCI) was used to classify comorbidities. The Big Five Personality Test (B5T) was used to assess the basic personality dimensions. Speech comprehension was evaluated in quiet with the Freiburg monosyllable test and in noise with the Oldenburg sentence test.

RESULTS

After CI surgery, the total NCIQ score improved significantly (Δ 17.1 ± 14.7, p < 0.001). General QOL (WHOQOL-BREF, Δ 0.4 ± 9.9, p = 0.357), stress (Δ 0.25 ± 3.21, p = 0.486), and depressiveness (Δ 0.52 ± 3.21, p = 0.121) were unaffected by CI surgery. Patients without elevated depressiveness (p < 0.01) or stress (p < 0.001) had significantly better total NCIQ scores. The results of the multiple regression analyses show that, after adjusting for the CCI, personality, age, and mental health stress (ß = - 0.495, p < 0.001) was significantly associated with postoperative NCIQ outcome scores. Depressiveness and neuroticism had the strongest influence on the generic QOL (ß = - 0.286 and ß = - 0.277, p < 0.05).

CONCLUSION

Stress symptoms and personality traits are significant predictive factors for disease-specific QOL, as well as hearing status. This should be considered in the preoperative consultation and in optimizing the rehabilitation process.

Sleep Quality and Insomnia Are Associated With Quality of Life in Functional Dyspepsia

Background

Sleep disturbances are common in patients with functional dyspepsia. Our aim was to assess the relationship between subjective sleep and quality of life and to identify factors associated with impaired sleep in functional dyspepsia.

Methods

One thousand two hundred and twenty patients referred for functional gastrointestinal disorders at a single tertiary care center between end 2017 and June 2019 were studied using a self-administered questionnaire. 355 patients with Rome IV-based functional dyspepsia were identified. Sleep was assessed using both the Pittsburgh Sleep Quality Index (PSQI) and the Insomnia Severity Index (ISI). The severity of dyspeptic symptoms was assessed using the Total Symptom Score (TSS). Quality of life was assessed by the GastroIntestinal Quality of Life Index (GIQLI). Anxiety and depression levels were evaluated using the Hospital Anxiety and Depression (HAD) scale.

Key Results

Among the 355 patients with functional dyspepsia, 66 (18.6%) patients displayed normal sleep quality whereas 289 (81.4%) patients had altered sleep quality. Functional dyspepsia patients with sleep disturbances were older (48.1 ± 15.4 vs. 41.4 ± 16.0, p = 0.0009), had decreased quality of life (GIQLI: 75.3 ± 18.5 vs. 92.1 ± 15.4, p < 0.0001), greater severity of their symptoms (TSS: 18.9 ± 3.6 vs. 17.2 ± 3.9, p = 0.0007), and higher anxiety and depression scores (HADS: 17.7 ± 7.2 vs. 11.9 ± 5.1, p < 0.0001). A correlation was found between sleep quality and quality of life [r = −0.43 (95% CI: −0.51 to −0.34), p < 0.0001]. Independent factors predicting poor sleep quality were age [OR 1.03 (95% CI = 1.01–1.05), p = 0.006], depression level [OR 1.27 (95% CI = 1.16–1.39); p < 0.0001], and the severity of dyspeptic symptoms [OR 1.13 (95% CI = 1.04–1.22); p = 0.004].

Conclusion and Inferences

A high prevalence of sleep disturbances was found in patients suffering from functional dyspepsia, with 81% of them having altered sleep quality and 61% having insomnia based on subjective assessment. Altered sleep quality and insomnia were associated with altered quality of life, higher severity of symptoms, and higher anxiety and depression scores in this disorder.

The impact of personality traits on pessary treatment outcomes in patients with pelvic organ prolapse

INTRODUCTION AND HYPOTHESIS

Personality traits can play an important role in outcomes of different chronic disorders. We hypothesize that the pessary treatment outcomes in symptomatic pelvic organ prolapse (POP) can also be influenced by personality traits.

METHODS

This prospective observational study included consecutive women with symptomatic POP seeking pessary treatment between December 2018 and January 2020. The personality profile was measured using the Eysenck Personality Questionnaire (EPQ-R) at baseline, and patient health-related quality of life (HRQoL) was measured using the Pelvic Floor Impact Questionnaire-7 (PFIQ-7) and the Pelvic Floor Distress Inventory (PFDI-20) at baseline and at 3 months. The correlation between HRQoL and personality traits was investigated by means of linear regression.

RESULTS

In total, 213 patients were included, of which 163 patients (76.5%) achieved success by the 3-month follow-up. No significant differences were found in the EPQ scores between the successful and unsuccessful groups. The scores on both the PFIQ-7 and PFDI-20 correlated significantly with neuroticism and correlated inversely with extraversion at both baseline and the 3-month follow-up. The degree of improvement in PFIQ-7 and PFDI-20 scores was not associated with personality traits.

CONCLUSIONS

Our data indicate that neurotic and introverted women were more bothered by POP-related symptoms, although the improvement in symptoms was not significantly associated with personality traits after 3 months of pessary treatment.

Personality traits are related to functional dyspepsia in a large sample of Iranian adults

BACKGROUND AND OBJECTIVE

Few studies have evaluated the association of personality traits with functional dyspepsia (FD). In the present study, we aimed to explore the relationship between different personality traits and FD in a sample of Iranian adults.

METHODS

This cross-sectional study was conducted on 4763 adults. FD was evaluated using a modified and validated Persian version of the Rome III questionnaire for the diagnosis of functional gastrointestinal disorders. Personality traits were assessed using the five-factor model. Logistic regression was used for data analysis.

RESULTS

After controlling for various potential confounders, neuroticism (OR = 1.043; 95% CI: 1.028, 1.059), agreeableness (OR = 0.965; 95% CI: 0.952, 0.978), extraversion (OR = 0.985; 95% CI: 0.970, 0.990), openness (OR = 0.981; 95% CI: 0.966, 0.996), and conscientious (OR = 0.980; 95% CI: 0.968, 0.991) scores were associated with risk of FD. Similar significant associations were observed in stratified analyses by sex, except for openness which tended to decrease the risk of FD marginally in women (OR = 0.983, 95% CI: 0.966, 1.001) and in men (OR = 0.979, 95% CI: 0.955, 1.003) after adjusting for multiple confounding variables.

CONCLUSION

Our study showed that the higher scores of extraversion, conscientiousness, openness, and agreeableness are independently associated with a lower risk of FD in Iranian general population while higher scores of neuroticism increase the risk of FD.

Clinical Practice Guidelines for Functional Dyspepsia in Korea

Functional dyspepsia (FD) is a chronic upper gastrointestinal (GI) symptom complex that routine diagnostic work-up, such as endoscopy, blood laboratory analysis, or radiological examination, fails to identify a cause. It is highly prevalent in the World population, and its response to the various available therapeutic strategies is only modest because of the heterogenous nature of its pathogenesis. Therefore, FD represents a heavy medical burden for healthcare systems. We constituted a guideline development committee to review the existing guidelines on the management of functional dyspepsia. This committee drafted statements and conducted a systematic review and meta-analysis of various studies, guidelines, and randomized control trials. External review was also conducted by selected experts. These clinical practice guidelines for FD were developed based on evidence recently accumulated with the revised version of FD guidelines released in 2011 by the Korean Society of Neurogastroenterology and Motility. These guidelines apply to adults with chronic symptoms of FD and include the diagnostic role of endoscopy, Helicobacter pylori screening, and systematic review and meta-analyses of the various treatment options for FD (proton pump inhibitors, H.pylori eradication, and tricyclic antidepressants), especially according to the FD subtype. The purpose of these new guidelines is to aid the understanding, diagnosis, and treatment of FD, and the targets of the guidelines are clinicians, healthcare workers at the forefront of patient care, patients, and medical students. The guidelines will continue to be revised and updated periodically.

Association between psycho-psychological factors and functional dyspepsia in elderly patients: Effect on activity of daily living score

AIM

To analyze the association between psycho-psychological factors and functional dyspepsia (FD) in elderly patients and the effect on patients' activity of daily living (ADL) score.

METHODS

Sixty elderly psychiatric patients with FD admitted to Shaoxing Seventh People's Hospital from August 2016 to September 2017 were selected as a study group, and 60 patients with FD with good mental status were selected as a control group. Psycho-psychological status and gastric function indexes were tested in both groups. The self-rating anxiety scale, self-rating depression scale, 24 h heart rate variability and water stress test were also used to assess the patients in the two groups.

RESULTS

The self-rating anxiety scale and self-rating depression scale scores of elderly patients in the study group were significantly higher than those in the control group (P < 0.05), and the number of patients with anxiety and depression in the study group was significantly higher than that in the control group (P < 0.05). The initial sensation and maximum tolerance of the water load test in the study group were significantly lower than those in the control group (P < 0.05), and the time to semi-emptying of gastric solids in the study group was significantly longer than that in the control group (P < 0.05). The incidence of adverse reactions in the study group was significantly lower than that in the control group (P < 0.05). ADL scores of elderly patients in the study group were significantly higher than those in the control group before and after treatment (P < 0.05).

CONCLUSION

Psycho-psychological status of patients is closely related to the development and progression of FD, and may cause damage to the gastric sensory function and motor function of the patients.

Focusing on the Differences of Resting-State Brain Networks, Using a Data-Driven Approach to Explore the Functional Neuroimaging Characteristics of Extraversion Trait

In recent years, functional magnetic resonance imaging (fMRI) has been widely used in studies that explored the personality-brain association. Researches on personality neuroscience have the potential to provide personality psychology with explanatory models—that is, why people differ from each other rather than how they differ from each other (DeYoung and Gray, 2009). As one of the most important dimensions of personality traits, extraversion is the most stable core and a universal component in personality theory. The aim of the present study was to employ a fully data-driven approach to study the brain mechanism of extraversion in a sample of 111 healthy adults. The Eysenck Personality Questionnaire (EPQ) was used to measure the personality characteristics of all the subjects. We investigated whether the subjects can be grouped into highly homogeneous communities according to the characteristics of their intrinsic connectivity networks (ICNs). The resultant subjects communities and the representative characteristics of ICNs were then associated to personality concepts. Finally, we found one ICN (salience network) whose subject community profiles exhibited significant associations with Extraversion trait.

Research progress on functional dyspepsia

Functional dyspepsia (FD) is considered to be a series of integrated responses to dysfunction of the brain-gut axis caused by a combination of biological factors and socio-psychological factors. Gastrointestinal motility disorder and mental emotional disorder are important factors leading to the development of FD, and abnormal function of the brain-gut axis is the core mechanism of FD pathogenesis. The high incidence of FD has caused a high degree of attention. In this paper, we will review the latest advances in the understanding of the pathogenesis of FD and in its treatment.
