Pragmatic detection of anxiety and depression in a prospective cohort of voice outpatient clinic attenders

OBJECTIVE

To evaluate diagnostic performance of the emotional domain of the VoiSS questionnaire compared with the Hospital Anxiety and Depression Scale (HADS).

DESIGN

Cross-sectional questionnaire study.

SETTING

Tertiary referral centre voice clinic.

PARTICIPANTS

210 consecutive voice clinic patients.

MAIN OUTCOME MEASURES

Screening with VoiSS and HADS questionnaires. Paired comparison, correlation, multinomial logistic regression and receiver-operating characteristic (ROC) curve analysis.

RESULTS

A total of 177 returned complete data sets. Ninety-six patients (54.2%) had functional dysphonia, and 81 (45.8%) had organic laryngeal disorders. Mean total VoiSS score = 39.7/120 (standard deviation (sd) 22.2). Mean emotional VoiSS subscale = 7.6/22 (sd 7.5). Mean HADS anxiety = 6.5/21 (sd 5.2) and depression mean = 7.1/21 (sd 4.8). There were 35 (20%) borderline anxiety and/or depression scores and 30 (17%) scores considered positive for 'caseness'. There was strong correlation between emotional VoiSS and HADS anxiety (Spearman's Rho = 0.68, P < 0.001) and HADS depression (Spearman's Rho = 0.62, P < 0.001). ROC curve analysis exhibited significant association between emotional VoiSS and HADS 'caseness' (area under curve = 0.88). In addition, functional dysphonia patients had lower mean VoiSS and HADS scores than patients with identifiable laryngeal abnormalities.

CONCLUSION

The VoiSS emotional subscale strongly correlates with HADS anxiety and depression scores and could be used as a measure of psychological distress. This could allow targeted psychological strategies, without additional psychometric questionnaires. Functional dysphonia has less association with psychological distress than certain organic laryngological disorders.

Reliability of self-reporting of antibiotic consumption in the community - Index of Reliability

WHAT IS KNOWN AND OBJECTIVE

To date, there is no evidence to indicate the reliability of how patients self-report their own antibiotic usage in the community. Such data are fundamental in supporting antimicrobial stewardship practices, and so there is a need to determine its accuracy and reliability.

COMMENT

Patients in the community (n = 476) were required to recollect their antibiotic usage in the past three months. Simultaneously, similar information was obtained by careful extraction from their respective medical notes, which was qualitatively compared with the patient's recollection. Overall, concordance was high (88·1%), but age (<20 and >80 years) and sex (female) were significant factors of reliability.

WHAT IS NEW AND CONCLUSION

This study suggests that basic self-reporting of antibiotic usage amongst patients is relatively reliable, with increasing accuracy with years until 80 years. Where such information is critical, the current study can help decide who to interview and whose notes to interrogate, in the quest to obtain reliable and accurate information.

Home range use and movement patterns of the yellow moray eel Gymnothorax prasinus

This study investigated the movement patterns of yellow moray eels Gymnothorax prasinus using acoustic telemetry. Gymnothorax prasinus were found to use multiple sites within a localized area or home range.

A novel educational tool for teaching ocular ultrasound

Ocular ultrasound is now in increasing demand in routine ophthalmic clinical practice not only because it is noninvasive but also because of ever-advancing technology providing higher resolution imaging. It is however a difficult branch of ophthalmic investigations to grasp, as it requires a high skill level to interface with the technology and provide accurate interpretation of images for ophthalmic diagnosis and management. It is even more labor intensive to teach ocular ultrasound to another fellow clinician. One of the fundamental skills that proved difficult to learn and teach is the need for the examiner to “mentally convert” 2-dimensional B-scan images into 3-dimensional (3D) interpretations. An additional challenge is the requirement to carry out this task in real time. We have developed a novel approach to teach ocular ultrasound by using a novel 3D ocular model. A 3D virtual model is built using widely available, open source, software. The model is then used to generate movie clips simulating different movements and orientations of the scanner head. Using Blender, Quicktime motion clips are choreographed and collated into interactive quizzes and other pertinent pedagogical media. The process involves scripting motion vectors, rotation, and tracking of both the virtual stereo camera and the model. The resulting sequence is then rendered for twinned right- and left-eye views. Finally, the twinned views are synchronized and combined in a format compatible with the stereo projection apparatus. This new model will help the student with spatial awareness and allow for assimilation of this awareness into clinical practice. It will also help with grasping the nomenclature used in ocular ultrasound as well as helping with localization of lesions and obtaining the best possible images for echographic diagnosis, accurate measurements, and reporting.

A phase II trial of neoadjuvant ABI-007, carboplatin, and gemcitabine (ACG) in patients with locally advanced carcinoma of the bladder

244

Background: Neoadjuvant cisplatin-based chemotherapy benefits patients with bladder cancer, particularly in the 30% with pathologic complete response (pCR) at cystectomy. Many patients with bladder cancer are not candidates for cisplatin. Taxane-based regimens have activity in urothelial cancer. ABI-007 is an albumin-bound paclitaxel with increased activity and decreased toxicity compared to standard paclitaxel preparations.

Methods: Eligible pts have T2-4,N0,M0 or Tany,N1- 3,M0 bladder cancer with ECOG PS 0-1, and adequate marrow (granulocyte count > 1,500/mm3, platelet > 100,000/mm3, and hemoglobin > 9.0 g/dl), hepatic (transaminases < 2.5 X upper limit of normal, alkaline phosphatase < 2.5 X upper limit of normal, and bilirubin < 1.5 mg/dl) and renal function (serum creatinine < 2.0 mg/dl and/or creatinine clearance > 40 ml/min). Pts are treated with intravenous ABI-007 260 mg/m2 and carboplatin (target area under the curve=5) on day 1 with gemcitabine 800 mg/m2 on days 1 and 8, followed by radical cystectomy after three cycles of therapy. The primary study endpoint is the proportion of patients with pCR at cystectomy.

Results: 27 patients have been enrolled. By clinical staging, 20 had T2 disease, 5 had T3, 2 had T4, and 2 had nodal enlargement. All are evaluable for toxicity with 22 evaluable for response (exclusions-3 for change in dose schedule, 1 each for refusal of cystectomy and withdrawal from study). 25/27 patients received all three cycles (78 total cycles) with doses reduced in 26 cycles for toxicity. All patients had transient grade 3-4 neutropenia and 17 received filgrastim, but only two had febrile neutropenia. Six pts had pCR with an additional 5 having residual carcinoma in situ (CIS) and 1 with T1 disease at cystectomy. 54% of evaluable patients had no muscle invasive disease at cystectomy.

Conclusions: Neoajuvant ACG is active in bladder cancer with pCR rate nearing 30% and nearly as many patients with CIS but no residual invasive disease. Marrow toxicity is significant but manageable.

Optimisation of storage conditions for maintaining culturability of penicillin-susceptible and penicillin-resistant isolates of Streptococcus pneumoniae in transport medium

Methods employed by the World Health Organization (WHO) are used during this study to determine the optimum storage conditions for maintaining the culturability of Streptococcus pneumoniae in skimmed milk, tryptone, glucose and glycerin (STGG) transport medium. A comparison of S. pneumoniae strains sensitive and resistant to penicillin showed no significant difference in their survival ability in STGG medium. Furthermore, it is confirmed that storage at -70 degrees C remains most effective for maintaining viability by culture of S. pneumoniae. Storage at -20 degrees C would only be acceptable in the short-term, while storage at +4 degrees C is not recommended. Of note, this study has shown STGG medium at room temperature to be an efficient growth medium for pneumococci in the short-term. This work will help to establish robust sampling protocols when performing community studies to ensure culturability of comparison between community and laboratory pneumococci survival.
