The prevalence and impact of psychiatric symptoms in an undiagnosed diseases clinical program

Retrograde cricopharyngeus dysfunction: How does the inability to burp affect daily life?

BACKGROUND

Retrograde cricopharyngeus dysfunction (R-CPD), a condition first detailed in 1987 and termed in 2019, refers to the cricopharyngeal muscle's inability to relax to allow the retrograde passage of gas. Limited research exists on the fundamental characteristics of this condition, including its impact on one's life. The purpose of this study is to characterize R-CPD and how the inability to burp affects the social lives of people who suffer from it.

METHODS

A Qualtrics survey was distributed on the subreddit "r/noburp," a community of 26,000 individuals sharing information about R-CPD. Adults aged 18-89 experiencing R-CPD symptoms were invited to participate. Participants reported on their experiences with R-CPD and its effects on social life on a 4-point Likert scale (1 = strongly disagree to 4 = strongly agree). Data was analyzed using descriptive statistics.

KEY RESULTS

Among the 199 respondents, the mean age was 30.9, and gender identity was 74%/25% female/male. 99% reported inability to burp, 98% reported abdominal bloating, 93% reported socially awkward gurgling noises, 89% reported excessive flatulence, and 55% reported difficulty vomiting. Only half discussed their symptoms with their primary care provider (PCP), and 90% disagreed with receiving adequate help. Average Likert scores indicated embarrassment (3.4), anxiety/depression (3.1), negative impact on relationships (2.6), and work disruption (2.7) due to R-CPD.

CONCLUSIONS & INFERENCES

R-CPD is unfamiliar to many healthcare providers, leaving patients underserved. It not only affects daily life but also personal and professional relationships. Raising awareness by understanding disease basic features may increase diagnosis and treatment rates, improving quality of life.

Psychological distress of adult patients consulting a center for rare and undiagnosed diseases: a cross-sectional study

BACKGROUND

Centers for rare diseases serve as contact points for patients with complex, often undiagnosed complaints and persistent somatic symptoms of heterogeneous origin. Little is known about psychological distress of patients consulting these centers.

OBJECTIVES

To better understand psychological distress of adult patients presenting at a center for rare diseases by determining the proportion of patients screening positive for depressive, anxiety, and somatic symptom disorders (SSD) and to identify factors associated with increased psychopathology.

METHODS

Cross-sectional data from the routine care registry of the Martin Zeitz Center for Rare Diseases (MZCSE) at the University Medical Center Hamburg-Eppendorf in Germany was retrieved and analyzed. We included all adult patients presenting between October 01,2020 and September 30,2021, who gave written informed consent.

MEASURES

Sociodemographic variables, medical history and healthcare utilization, as well as validated measures to screen for a depressive disorder (PHQ-8), an anxiety disorder (GAD-7), and SSD (PHQ-15, SSD-12).

RESULTS

N = 167 patients were included (age 44.5 ± 14.3 years, 64.7% female). A total of 40.7% of the patients screened positive for a depressive disorder (PHQ-8 ≥ 10), 27.5% for an anxiety disorder (GAD-7 ≥ 10) and 45.0% screened positive for SSD (PHQ-15 ≥ 9 & SSD-12 ≥ 23). Factors associated with increased psychopathology included the number of symptoms, the number of different specialties consulted before and past psychotherapy.

CONCLUSIONS

Patients presenting at centers for rare diseases are likely to experience high rates of psychological distress. Systematically screening patients with rare and undiagnosed diseases for mental disorders can help to detect those at risk at an early stage and initiate adequate psychological care.

Transdiagnostic psychiatry: Symptom profiles and their direct and indirect relationship with well-being

BACKGROUND

Heterogeneity and comorbidity in psychiatric disorders are common, however, little is known about the impact on well-being and the role of functional limitations. We aimed to identify transdiagnostic psychiatric symptom profiles and to study their association with well-being and the mediating role of functional limitations in a naturalistic psychiatric patient group.

METHODS

We used four disorder-specific questionnaires to assess symptom severity within a sample of 448 psychiatric patients with stress-related and/or neurodevelopmental disorders and 101 healthy controls. Using both exploratory and confirmatory factor analyses we identified transdiagnostic symptom profiles, which we entered into a linear regression analysis to assess their association with well-being and the mediating role of functional limitations in this association.

RESULTS

We identified eight transdiagnostic symptom profiles, covering mood, self-image, anxiety, agitation, empathy, non-social interest, hyperactivity and cognitive focus. Mood and self-image showed the strongest association with well-being in both patients and controls, while self-image also showed the highest transdiagnostic value. Functional limitations were significantly associated with well-being and fully mediated the relationship between cognitive focus and well-being.

LIMITATIONS

The participant sample consisted of a naturalistic group of out-patients. While this strengthens the ecological validity and transdiagnostic perspective of this study, the patients with a single neurodevelopmental disorder were underrepresented.

CONCLUSION

Transdiagnostic symptom profiles are valuable in understanding what reduces well-being in psychiatric populations, thereby opening new avenues for functionally meaningful interventions.

The Burden of Undiagnosed Adults With Attention-Deficit/Hyperactivity Disorder Symptoms in Japan: A Cross-Sectional Study

Background

Symptoms experienced by adult patients with attention-deficit/hyperactivity disorder (ADHD) frequently result in functional impairment across academic/occupational functioning, daily life, and social functioning. A substantial proportion of undiagnosed and untreated ADHD has been suggested in Japan. This study aims to better understand the potential undiagnosed ADHD population in Japan by quantifying the burden associated with ADHD symptoms through a comparison of the prevalence of comorbidities, health-related quality of life (HRQoL), work productivity and activity impairment (WPAI), and healthcare resource utilization (HRU) between undiagnosed potential ADHD respondents who were screened positive and negative using Adult ADHD Self-Report Scale (ASRS)-v1.1.

Methodology

Respondents from Japan National Health and Wellness Survey 2016 who answered ASRS-v1.1 without an ADHD diagnosis were included. Respondents checking ≥4 items from ASRS-A and ≥9 from ASRS-A+B were classified as ASRS A+ (n = 309) and ASRS AB+ (n = 227), respectively. ASRS negative (n = 9,280) were respondents who were neither ASRS A+ nor ASRS AB+. Data on the presence of comorbidities, HRQoL, WPAI, and HRU were compared.

Results

ASRS A+ and ASRS AB+ respondents reported higher coexistence of mental comorbidities (depression, generalized anxiety disorder, bipolar disorder, obsessive-compulsive disorder, etc.), sleep problems (insomnia, narcolepsy, sleep apnea, etc.), and physical comorbidities (non-alcoholic steatohepatitis, allergy, and asthma). They also reported greater WPAI and HRU and lower HRQoL than matched ASRS-negative respondents.

Conclusions

A significantly higher burden was identified among undiagnosed adults with potential ADHD symptoms. Appropriate diagnosis may help those at risk or those who present with symptoms overlapping with ADHD.

The Relationship of Post-traumatic Stress Disorder to End-of-life Care Received by Dying Veterans: a Secondary Data Analysis

BACKGROUND

Post-traumatic stress disorder (PTSD) can be exacerbated by subsequent trauma, but it is unclear if symptoms are worsened by impending death. PTSD symptoms, including hyperarousal, negative mood and thoughts, and traumatic re-experiencing, can impact end-of-life symptoms, including pain, mood, and poor sleep. Thus, increased symptoms may lead to increased end-of-life healthcare utilization.

OBJECTIVES

To determine if veterans with PTSD have increased end-of-life healthcare utilization or medication use and to examine predictors of medication administration.

DESIGN

Secondary analysis of a stepped-wedge design implementation trial to improve end-of-life care for Veterans Affairs (VA) inpatients. Outcome variables were collected via direct chart review. Analyses included hierarchical, generalized estimating equation models, clustered by medical center.

SUBJECTS

Veterans, inpatient at one of six VA facilities, dying between 2005 and 2011.

MAIN MEASURES

Emergency room (ER) visits, hospitalizations, and medication administration in the last 7 days of life.

KEY RESULTS

Of 5341 veterans, 468 (8.76%) had PTSD. Of those, 21.4% (100/468) had major depression and 36.5% (171/468) had anxiety. Veterans with PTSD were younger (mean age 65.4 PTSD, 70.5 no PTSD, p < 0.0001) and had more VA hospitalizations and ER visits in the last 12 months of life (admissions: PTSD 2.8, no PTSD 2.4, p < 0.0001; ER visits: 3.2 vs 2.5, p < 0.0001). PTSD was associated with antipsychotic administration (OR 1.52, 95% CI 1.06-2.18). Major depression (333/5341, 6.2%) was associated with opioid administration (OR 1.348, 95% CI 1.129-1.609) and benzodiazepines (OR 1.489, 95% CI 1.141-1.943). Anxiety disorders (778/5341, 14.6%) were only associated with benzodiazepines (OR 1.598, 95% CI 1.194-2.138).

CONCLUSIONS

PTSD's association with increased end-of-life healthcare utilization and increased antipsychotic administration in the final days of life suggests increased symptom burden and potential for terminal delirium in individuals with PTSD. Understanding the burden of psychiatric illness and potential risks for delirium may facilitate the end-of-life care for these patients.
