Dual Diagnosis in Older Adults: A Review

Dual diagnosis is associated with frequent relapse, poor treatment engagement and overall unsatisfactory treatment outcomes. A comprehensive review of the contemporary literature examining this issue was conducted, finding a paucity of literature concerning dual diagnosis in older adults. Of the literature appraised for this review, a number of studies examined US Veteran's Affairs populations, which were largely male. Studies concerning older mental health populations were scarce. During the literature search, a number of background studies that influenced contemporary research regarding dual diagnosis in older adults were found; these studies were examined regarding their contribution to contemporary paradigms concerning older adults with co-occurring mental illness and substance use disorders. This review presents the results of the contemporary literature concerning dual diagnosis in older adults. Several recurring themes emerge from the literature, including the notion of a statistically small population that, in absolute terms, represents a sizeable number of individuals coming to the attention of aged mental health services in the future. Additionally, the potential for under-diagnosis in this cohort is highlighted, potentially creating a hidden population of older adults with dual diagnosis.     

Nonallergic Rhinitis

Rhinitis is normally defined by the symptoms of nasal congestion, postnasal drainage, rhinorrhea, and sneezing. It has been associated with various pathologic changes, but can occur in the absence of any inflammation. Thus, the diagnosis is based on the clinical presentation. There are no clear-cut criteria to distinguish when rhinitis becomes chronic, but in its chronic form, it can be complex. Chronic forms of rhinitis that occur in the absence of any detectable specific IgE against relevant aeroallergens in its broadest sense can be called chronic nonallergic rhinitis. This review will concentrate on chronic nonallergic rhinitis in its various forms, discussing the epidemiology, underlying mechanisms, and its therapy.     

Performance of Reperfusion Therapy and Hospital Mortality in ST-Elevation Myocardial Infarction Patients with Non-Chest Pain Complaints

Purpose

ST-elevation myocardial infarction (STEMI) patients may visit the emergency department (ED) complaining of sensations of pain other than the chest. We investigated our performance of reperfusion therapy for STEMI patients presenting with non-chest pains.

Materials and Methods

This was a retrospective observational cohort study. STEMI patients who underwent primary percutaneous coronary intervention (PCI) were divided into a chest pain group and a non-chest pain group. Clinical differences between the two groups and the influence of presenting with non-chest pains on door-to-electrocardiograms (ECG) time, door-to-balloon time, and hospital mortality were evaluated.

Results

Of the 513 patients diagnosed with STEMI, 93 patients presented with non-chest pains. Patients in the non-chest pain group were older, more often female, and had a longer symptom onset to ED arrival time and higher Killip class than patients in the chest pain group. There was a statistically significant delay in door-to-ECG time (median, 2.0 min vs. 5.0 min; p<0.001) and door-to-balloon time (median, 57.5 min vs. 65.0 min; p<0.001) in patients without chest pain. In multivariate analysis, presenting with non-chest pains was an independent predictor for hospital mortality (odds ratio, 2.3; 95% confidence interval, 1.1-4.7). However, door-to-ECG time and door-to-balloon time were not factors related to hospital mortality.

Conclusion

STEMI patients presenting without chest pain showed higher baseline risk and hospital mortality than patients presenting with chest pain. ECG acquisition and primary PCI was delayed for patients presenting with non-chest pains, but not influencing hospital mortality. Efforts to reduce pre-hospital time delay for these patients are necessary.     

A pilot wastewater‐based epidemiology assessment of anabolic steroid use in Queensland,Australia

Anabolic‐androgenic steroids are synthetic compounds prohibited due to their performance‐enhancing characteristics. The use of these substances is known to cause health‐related issues, which highlights the importance of being able to evaluate the scale of consumption by the general population. However, most available research on the analysis of anabolic steroids is focused on animals and athletes in connection with doping. The potential of wastewater‐based epidemiology as an intelligence tool for the assessment of community level use of anabolic steroids is presented herein. A liquid chromatography tandem mass spectrometry method was developed for the analysis of 10 anabolic‐androgenic steroids and 14 endogenous hormones in influent wastewater. The validated method was applied to sixteen 24‐hour composite wastewater influent samples that were collected over a period of five years from two wastewater treatment plants in Queensland, Australia. Nine investigated compounds were found to be present at concentrations between 14 and 611 ng L^?1 which translated into 3–104 mg excreted per 1000 individuals per day. It was concluded that the developed analytical method is suitable for the analysis of AAS in wastewater matrix. Additionally, both the inclusion of metabolites and further investigation into deconjugation by enzymatic hydrolysis would aid in understanding and evaluating community anabolic steroid use. For the first time, this study presents the application of wastewater‐based epidemiology on anabolic‐androgenic steroids in Australia.     

Validity of standard gamble estimated quality of life in acute venous thrombosis

Introduction

The standard gamble is considered the ‘gold standard’ technique for measuring quality of life. We recently used the standard gamble to estimate quality of life in acute venous thrombosis, and found unexpected variability in the responses. The current study aimed to explore the reasons for variability by comparing the standard gamble technique in patients with acute venous thrombosis to other quality of life measurement tools.

Materials and Methods

Thrombosis clinic patients treated for venous thrombosis were eligible to participate. Patients evaluated their current health state by performing a standard gamble interview, reporting on a visual analogue scale, completing the SF-36 and disease specific questionnaires (PEmb-Qol and VEINES-QOL/Sym). Validity was assessed by correlating the standard gamble utilities with the other methods. Test-retest reliability, responsiveness and acceptability were also assessed.

Results

Forty-four patients were interviewed, with 16 attending for a repeat interview. The median standard gamble utility was 0.97 (0.84-1.0), SF-6D 0.64 (0.59 - 0.80) and visual analogue score 70 (60 - 80). Participants with pulmonary embolism had lower standard gamble estimates than those with deep vein thrombosis. There was good discriminant validity in that the standard gamble estimates were not associated with risk taking behavior, negative outlook, sex or education. Test-retest reliability with the standard gamble was moderate and there was evidence of a ceiling effect.

Conclusions

Standard gamble utilities are higher than other methods of measuring quality of life in venous thrombosis. The choice of utility values adopted in studies will impact on future economic studies.
