Multiple Comorbidities of 21 Psychological Disorders and Relationships With Psychosocial Variables: A Study of the Online Assessment and Diagnostic System Within a Web-Based Population

BackgroundWhile research in the area of e-mental health has received considerable attention over the last decade, there are still many areas that have not been addressed. One such area is the comorbidity of psychological disorders in a Web-based sample using online assessment and diagnostic tools, and the relationships between comorbidities and psychosocial variables.ObjectiveWe aimed to identify comorbidities of psychological disorders of an online sample using an online diagnostic tool. Based on diagnoses made by an automated online assessment and diagnostic system administered to a large group of online participants, multiple comorbidities (co-occurrences) of 21 psychological disorders for males and females were identified. We examined the relationships between dyadic comorbidities of anxiety and depressive disorders and the psychosocial variables sex, age, suicidal ideation, social support, and quality of life.MethodsAn online complex algorithm based on the criteria of the Diagnostic and Statistical Manual of Mental Disorders, 4th edition, Text Revision, was used to assign primary and secondary diagnoses of 21 psychological disorders to 12,665 online participants. The frequency of co-occurrences of psychological disorders for males and females were calculated for all disorders. A series of hierarchical loglinear analyses were performed to examine the relationships between the dyadic comorbidities of depression and various anxiety disorders and the variables suicidal ideation, social support, quality of life, sex, and age.ResultsA 21-by-21 frequency of co-occurrences of psychological disorders matrix revealed the presence of multiple significant dyadic comorbidities for males and females. Also, for those with some of the dyadic depression and the anxiety disorders, the odds for having suicidal ideation, reporting inadequate social support, and poorer quality of life increased for those with two-disorder comorbidity than for those with only one of the same two disorders.ConclusionsComorbidities of several psychological disorders using an online assessment tool within a Web-based population were similar to those found in face-to-face clinics using traditional assessment tools. Results provided support for the transdiagnostic approaches and confirmed the positive relationship between comorbidity and suicidal ideation, the negative relationship between comorbidity and social support, and the negative relationship comorbidity and quality of life.

The Diagnostic Validity and Reliability of an Internet-Based Clinical Assessment Program for Mental Disorders

Background

Internet-based assessment has the potential to assist with the diagnosis of mental health disorders and overcome the barriers associated with traditional services (eg, cost, stigma, distance). Further to existing online screening programs available, there is an opportunity to deliver more comprehensive and accurate diagnostic tools to supplement the assessment and treatment of mental health disorders.

Objective

The aim was to evaluate the diagnostic criterion validity and test-retest reliability of the electronic Psychological Assessment System (e-PASS), an online, self-report, multidisorder, clinical assessment and referral system.

Methods

Participants were 616 adults residing in Australia, recruited online, and representing prospective e-PASS users. Following e-PASS completion, 158 participants underwent a telephone-administered structured clinical interview and 39 participants repeated the e-PASS within 25 days of initial completion.

Results

With structured clinical interview results serving as the gold standard, diagnostic agreement with the e-PASS varied considerably from fair (eg, generalized anxiety disorder: κ=.37) to strong (eg, panic disorder: κ=.62). Although the e-PASS’ sensitivity also varied (0.43-0.86) the specificity was generally high (0.68-1.00). The e-PASS sensitivity generally improved when reducing the e-PASS threshold to a subclinical result. Test-retest reliability ranged from moderate (eg, specific phobia: κ=.54) to substantial (eg, bulimia nervosa: κ=.87).

Conclusions

The e-PASS produces reliable diagnostic results and performs generally well in excluding mental disorders, although at the expense of sensitivity. For screening purposes, the e-PASS subclinical result generally appears better than a clinical result as a diagnostic indicator. Further development and evaluation is needed to support the use of online diagnostic assessment programs for mental disorders.

Oral healthcare considerations for the pregnant woman

Pregnancy is a period of both joy and anxiety in a woman's life and is characterized by various physiological changes in her body brought about by the circulating female sex hormones. The oral cavity is also the seat of changes and these physiologic changes of pregnancy need to be addressed while managing the pregnant woman in the dental clinic. The main goal is to minimize the occurrence of any complications that might harm the mother-to-be and/or the unborn child. Preventive, emergency, and routine dental procedures are all deemed suitable during various phases of pregnancy, with some treatment modifications and initial planning. Clinical Relevance: The dentist should be in a position to manage pregnant women in clinical practice effectively.     

Ectopic pregnancy

Ectopic pregnancy is a high-risk diagnosis that is increasing in frequency and is still commonly missed in the emergency department. The emergency physician needs a high index of suspicion and must understand that the history, physical examination, and a single quantitative beta-hCG level cannot reliably rule out an ectopic pregnancy. Most pregnant patients who present to the emergency department during the first trimester with abdominal or pelvic pain, regardless of the presence of vaginal bleeding, should undergo further evaluation with ultrasonography. Ultrasound findings in conjunction with quantitative beta-hCG levels guide the management of the patient.     

LCPT once‐daily extended‐release tacrolimus tablets versus twice‐daily capsules: a pooled analysis of two phase 3 trials in important de novo and stable kidney transplant recipient subgroups

African‐American and elderly kidney transplant recipients (KTR) have increased risk for poor clinical outcomes post‐transplant. Management of immunosuppression may be challenging in these patients and contribute to worse outcomes. A novel once‐daily formulation of tacrolimus (LCPT) has demonstrated noninferiority, similar safety, improved bioavailability, a consistent concentration time profile, and less peak and peak‐trough fluctuations vs. tacrolimus twice‐daily (Tac BID). This pooled analysis of two phase 3 randomized, controlled trials, including 861 (LCPT N = 428; Tac BID N = 433; 38% of patients were stable KTR, and 62% were de novo KTR) patients, examined the efficacy of LCPT in KTR subgroups (blacks, females, and age ≥65). Overall, treatment failure [death, graft failure, centrally read biopsy‐proven acute rejection (BPAR), or lost to follow‐up] at 12 months was as follows: LCPT: 11.9%, BID Tac: 13.4% [?1.48% (?5.95%, 2.99%)]. BPAR rates were as follows: LCPT: 8.2%, Tac BID: 9.5% [?1.29% (?5.14%, 2.55%)]. Numerically, fewer treatment failure events with LCPT were found in the majority of subgroups, with significantly less treatment failure associated with LCPT among black KTR [?13.82% (?27.22%, ?0.31%)] and KTR ≥65 [?13.46% (?25.27%, ?0.78%)]. This pooled analysis suggests numerically lower efficacy failure rates associated with LCPT among high‐risk subgroups, in particular black KTR and KTR ≥65 years old.
