Comparison of the Early Childhood Oral Health Impact Scale (ECOHIS-4D) and Child Health Utility Index (CHU-9D) in children with oral diseases

OBJECTIVE

Accurate assessment of child oral health is important for guiding economic evaluations and informing healthcare decision-making. Early Childhood Oral Health Impact Scale (ECOHIS-4D) is a preference-based instrument that measures the oral health-related quality of life of young children. The aim of this study was to compare the utility scores of ECOHIS-4D and Child Health Utility Index (CHU-9D), against an oral health indicator to evaluate which utility score corresponds better with the oral health indicator.

METHOD

The ECOHIS-4D and CHU-9D were applied to 314 parent/child dyads from preschools in a primary healthcare setting in Perth, Western Australia. Four parameters were used to assess which instrument corresponds better with the oral health indicator (decayed, missing and filled teeth score-dmft score): (i) discrimination, the ability to discriminate between different clinical severity groups, (ii) external responsiveness, how much the utility values relate to the changes in dmft scores, (iii) correlation, the association between the two instruments and the related dimensions and (iv) differences in the utility values across the two instruments.

RESULTS

Most participants (81%) were 2-6 years old, and nearly 50% had a dmft score <3. ECOHIS-4D demonstrated a superior ability to differentiate between dmft severity groups and respond to changes in dmft scores. A significant weak correlation was observed between dmft and ECOHIS-4D (-0.26, 95%, CI -0.36 to -0.15) compared to a non-significant very poor correlation between dmft and CHU-9D (0.01, 95% CI -0.12 to 0.10). The utility scores of the two instruments had relatively good agreement towards good health and weak agreement towards poor health.

CONCLUSIONS

ECOHIS-4D, the oral health-specific instrument, is more sensitive in assessing children's oral health-related quality of life than the generic CHU-9D. Thus, ECOHIS-4D is more appropriate for utility estimates in economic evaluations of oral health-related interventions and resource allocation decision-making.

What is the usage of the Brisbane Evidence Based Language Test in clinical practice?: A speech language therapy survey

BACKGROUND

A number of practice barriers (e.g., time constraints, patient comorbidities and competing demands) exist as regards the evidence-based assessment of adult language within the acute hospital setting. There is need for an evidence-based, diagnostically validated, adaptable, comprehensive and efficient aphasia assessment. The Brisbane Evidence Based Language Test (EBLT) was developed to meet this need for a clinically appropriate and diagnostically robust assessment measure. Since the release of the EBLT, there has been no detailed investigation into speech and language therapists' (SLT) use and perceptions of the assessment. To inform future research and improvements to the EBLT, a better understanding of current language assessment practices, use and thoughts on the EBLT are required.

AIMS

To investigate SLTs' current language assessment practices; and to explore the current usage and future directions of the Brisbane EBLT.

METHODS & PROCEDURES

A convergent parallel mixed-methods study design with an electronic survey was utilized. The survey consisted of 16 multiple-choice, multiple-answer and free-text questions that explored respondents' perceptions of current language assessment measures, ideal language assessment features, Brisbane EBLT use, positives and negatives, and future directions for the EBLT. The survey was developed on Qualtrics and disseminated via email, social media and professional networks. Snowball sampling was used. Study inclusion criteria required participants to be qualified SLTs with clinical experience working with patients with aphasia. Quantitative data were analysed via descriptive and correlative statistics, and qualitative data were analysed via content analysis.

OUTCOMES & RESULTS

The survey was completed by 115 SLTs from Australia, New Zealand, the United States, the UK, Canada, France, Lebanon and Belgium. Many respondents identified that a range of assessments is required to meet SLT clinical needs in the assessment of aphasia. Key desirable assessment features reported were: comprehensive, efficient, evidence-based, responsive and flexible. The EBLT was the most frequently used standardized measure reported by respondents (used by 78.63%). The EBLT reportedly has many positive features; however, respondents indicated dislike of the form layout, scoring and responsiveness. The majority of respondents indicated that the development of additional EBLT tests (94.29%) and additional cut-off scores (95.15%) would benefit their clinical practice.

CONCLUSIONS & IMPLICATIONS

The study findings indicate that SLT assessment of language is complex and multifaceted. While the EBLT is reportedly used widely by SLTs, respondents identified areas for further research which would optimize the test's usability within their practice, to ultimately improve patient outcomes.

WHAT THIS PAPER ADDS

What is already known on the subject Previous studies have explored existing SLT adult language assessment practices within acute settings; however, the most recent comprehensive study was completed in 2010. In 2020, the development, diagnostic validation, intra- and interrater reliability of the Brisbane EBLT were published. As of yet there has not been an investigation into clinician use and perspectives of the assessment since its release. What this paper adds to existing knowledge This study provides contemporary data about international aphasia assessment practices, as well as descriptive and qualitative information on the current use of the Brisbane EBLT, and the positives, negatives, and future directions for the assessment measure. What are the potential or actual clinical implications of this work? The study suggests that no one language assessment currently satisfies all SLTs' assessment needs. It additionally implies that a large proportion of SLTs believe that it is best practice to use multiple language assessment measures and select these based on the patient's presentation and context. Further research is required to aid the development of additional EBLT test versions and cut-off scores to improve SLT adult language assessment practices.

Inter-rater reliability, intra-rater reliability and internal consistency of the Brisbane Evidence-Based Language Test

Purpose: To examine the inter-rater reliability, intra-rater reliability, internal consistency and practice effects associated with a new test, the Brisbane Evidence-Based Language Test.Methods: Reliability estimates were obtained in a repeated-measures design through analysis of clinician video ratings of stroke participants completing the Brisbane Evidence-Based Language Test. Inter-rater reliability was determined by comparing 15 independent clinicians' scores of 15 randomly selected videos. Intra-rater reliability was determined by comparing two clinicians' scores of 35 videos when re-scored after a two-week interval.Results: Intraclass correlation coefficient (ICC) analysis demonstrated almost perfect inter-rater reliability (0.995; 95% confidence interval: 0.990-0.998), intra-rater reliability (0.994; 95% confidence interval: 0.989-0.997) and internal consistency (Cronbach's α = 0.940 (95% confidence interval: 0.920-1.0)). Almost perfect correlations (0.998; 95% confidence interval: 0.995-0.999) between face-to-face and video ratings were obtained.Conclusion: The Brisbane Evidence-Based Language Test demonstrates almost perfect inter-rater reliability, intra-rater reliability and internal consistency. High correlation coefficients and narrow confidence intervals demonstrated minimal practice effects with scoring or influence of years of clinical experience on test scores. Almost perfect correlations between face-to-face and video scoring methods indicate these reliability estimates have direct application to everyday practice.

Development and diagnostic validation of the Brisbane Evidence-Based Language Test

Purpose: To describe the development and determine the diagnostic accuracy of the Brisbane Evidence-Based Language Test in detecting aphasia.Methods: Consecutive acute stroke admissions (n = 100; mean = 66.49y) participated in a single (assessor) blinded cross-sectional study. Index assessment was the ∼45 min Brisbane Evidence-Based Language Test. The Brisbane Evidence-Based Language Test is further divided into four 15-25 min Short Tests: two Foundation Tests (severe impairment), Standard (moderate) and High Level Test (mild). Independent reference standard included the Language Screening Test, Aphasia Screening Test, Comprehensive Aphasia Test and/or Measure for Cognitive-Linguistic Abilities, treating team diagnosis and aphasia referral post-ward discharge.Results: Brisbane Evidence-Based Language Test cut-off score of ≤157 demonstrated 80.8% (LR+ =10.9) sensitivity and 92.6% (LR- =0.21) specificity. All Short Tests reported specificities of ≥92.6%. Foundation Tests I (cut-off ≤61) and II (cut-off ≤51) reported lower sensitivity (≥57.5%) given their focus on severe conditions. The Standard (cut-off ≤90) and High Level Test (cut-off ≤78) reported sensitivities of ≥72.6%.Conclusion: The Brisbane Evidence-Based Language Test is a sensitive assessment of aphasia. Diagnostically, the High Level Test recorded the highest psychometric capabilities of the Short Tests, equivalent to the full Brisbane Evidence-Based Language Test. The test is available for download from brisbanetest.org.Implications for rehabilitationAphasia is a debilitating condition and accurate identification of language disorders is important in healthcare.Language assessment is complex and the accuracy of assessment procedures is dependent upon a variety of factors.The Brisbane Evidence-Based Language Test is a new evidence-based language test specifically designed to adapt to varying patient need, clinical contexts and co-occurring conditions.In this cross-sectional validation study, the Brisbane Evidence-Based Language Test was found to be a sensitive measure for identifying aphasia in stroke.

Development of a novel selective agar for the isolation and detection of Bacillus anthracis

AIMS

The aim of this study was to develop a novel selective agar for the specific isolation and detection of Bacillus anthracis.

METHODS AND RESULTS

Based on published data on antibiotic resistance and susceptibility of B. anthracis and other closely related species of the Bacillus cereus sensu lato group, a new selective agar formulation termed CEFOMA (Bacillus CEreus sensu lato group-specific antibiotics, FOsfomycin, MAcrolides) was developed and evaluated. All tested strains of B. anthracis were able to grow on CEFOMA with the same colony number as on non-selective media, whereas CEFOMA inhibited the growth of the other species within the B. cereus sensu lato group. In comparison to other selective agars, CEFOMA had a superior performance and considerably reduced the total amount of accompanying flora in soil. Furthermore, B. anthracis was successfully isolated from deliberately spiked soil samples.

CONCLUSIONS

CEFOMA is a highly promising selective agar for the efficient isolation of B. anthracis from environmental samples with a large bacterial background flora.

SIGNIFICANCE AND IMPACT OF THE STUDY

The isolation of B. anthracis from environmental samples is severely impaired by the lack of adequate selective agars which suppress the growth of other bacteria. CEFOMA agar represents an important improvement and suitable alternative to currently used selective agars.

Diagnosis of aphasia in stroke populations: A systematic review of language tests

Background and purpose

Accurate aphasia diagnosis is important in stroke care. A wide range of language tests are available and include informal assessments, tests developed by healthcare institutions and commercially published tests available for purchase in pre-packaged kits. The psychometrics of these tests are often reported online or within the purchased test manuals, not the peer-reviewed literature, therefore the diagnostic capabilities of these measures have not been systematically evaluated. This review aimed to identify both commercial and non-commercial language tests and tests used in stroke care and to examine the diagnostic capabilities of all identified measures in diagnosing aphasia in stroke populations.

Methods

Language tests were identified through a systematic search of 161 publisher databases, professional and resource websites and language tests reported to be used in stroke care. Two independent reviewers evaluated test manuals or associated resources for cohort or cross-sectional studies reporting the tests’ diagnostic capabilities (sensitivity, specificity, likelihood ratios or diagnostic odds ratios) in differentiating aphasic and non-aphasic stroke populations.

Results

Fifty-six tests met the study eligibility criteria. Six “non-specialist” brief screening tests reported sensitivity and specificity information, however none of these measures reported to meet the specific diagnostic needs of speech pathologists. The 50 remaining measures either did not report validity data (n = 7); did not compare patient test performance with a comparison group (n = 17); included non-stroke participants within their samples (n = 23) or did not compare stroke patient performance against a language reference standard (n = 3). Diagnostic sensitivity analysis was completed for six speech pathology measures (WAB, PICA, CADL-2, ASHA-FACS, Adult FAVRES and EFA-4), however all studies compared aphasic performance with that of non-stroke healthy controls and were consequently excluded from the review.

Conclusions

No speech pathology test was found which reported diagnostic data for identifying aphasia in stroke populations. A diagnostically validated post-stroke aphasia test is needed.

HMPAO-SPECT bei zerebralen Anfällen

ln nine patients with suspected psychogenic seizures and in three patients with proven epileptic seizures HMPAO-SPECT was performed prior to and during seizure. In the patients with lateron-proven psychogenic seizures no, or only slight, changes of regional cerebral blood flow were found. Patients with proven epilepsy revealed partly normal findings interictally but during seizure a markedly increased circumscript blood flow was found in all patients. Even though PET is superior to SPECT with respect to spatial resolution, in the diagnosis of seizures HMPAO-SPECT has the advantage of enabling injection of the tracer during the seizure and the performance of the SPECT study subsequently.

[Peripartum management plan for patients with mental illnesses : Strategies to reduce the risk of postpartum relapse]

BACKGROUND

Transition to parenthood is challenging but for women with a history of recurrent psychiatric disorders becoming a mother has a number of additional issues. Women with a history of mood disorders or psychoses are at increased risk for exacerbation in the vulnerable postpartum period and fear the potential risk of medication during pregnancy for the unborn child as much as they fear a relapse. In these difficult situations women and their families seek advice and support from mental health providers and obstetricians.

METHODS AND RESULTS

Based on the treatment of 420 mentally ill women with a desire to have children and pregnancy and prospective documentation of 196 pregnancies over the last 10 years (2006-2016) the authors developed the Bonn concept of peripartum management (BKPM). The plan was designed to reduce the incidence and severity of postpartum relapses in women suffering from psychiatric disorders. Factors to be considered include antenatal and postpartum medication as well as reduction of stress and stimuli, sleep preservation, social support and help from the partner in caring for the baby. Of the 196 women in the BKPM only 4.6 % (n = 9) experienced a severe postpartum relapse with hospitalization. Additionally, the informed consent discussion with patient and partner as part of the peripartum management plan showed positive effects on how women and their families experienced autonomy and safety during pregnancy and postpartum.

DISCUSSION

Careful planning and monitoring with a structured perinatal management plan can reduce the risk of relapse in the perinatal period and thus support women with a history of mental disorder in the transition to motherhood. Therefore, the management concept employed in Bonn contributes to the major goal of current peripartum psychiatric care in developing effective prevention strategies for women at high risk.

Systematic review of the quality of clinical guidelines for aphasia in stroke management

RATIONALE, AIMS AND OBJECTIVES

Aphasia affects up to 38% of stroke survivors. Clinical guidelines can improve patient care and outcomes. Given the importance of aphasia management in stroke care, the purpose of this study was to systematically search for, retrieve and assess the quality of currently published clinical guidelines for aphasia in stroke management.

METHOD

Systematic search of bibliographic resources, publications, association websites, databases, Internet and pearling revealed multidisciplinary stroke and speech pathology-specific clinical guidelines, which were evaluated using the Appraisal of Guidelines and Research and Evaluation (AGREE) II tool. Guidelines obtaining a rigour of development score above 66.67% in AGREE II evaluations underwent further ADAPTE Collaboration tool analysis.

RESULTS

There was significant variability in methodological rigour, reporting of guideline development processes and scope of coverage of recommendations pertaining to aphasia management provided within the guidelines. The Australian Clinical Guidelines for Stroke Management (2010) and New Zealand Clinical Guidelines for Stroke Management (2010) achieved the highest scores (74% and 81%, respectively) in AGREE II analysis and both obtained a 'yes' in all seven ADAPTE domains. The Scottish Intercollegiate Guideline Network 108 (2008) guideline achieved 73% in AGREE II and six out of seven 'yes' in ADAPTE, however, contained no aphasia-specific recommendations. The Royal College of Speech and Language Therapists (2005) guideline provided the most comprehensive aphasia coverage, however, demonstrated lower methodological rigour in AGREE II (64%) and ADAPTE evaluations (three 'yes' out of seven).

CONCLUSION

Improvement is needed in the quality of methodological rigour in development and reporting within clinical guidelines, and in aphasia-specific recommendations within stroke multidisciplinary clinical guidelines.

The World Report on Disability as a blueprint for international, national, and local aphasia services

This commentary aims to extend the debate of the lead article authors (Wylie, McAllister, Davidson, and Marshall, 2013) by translating the nine recommendations of the World Report on Disability into a plan of action for the aphasia community. Solutions for the advancement of aphasia science and services are presented at international (macro), national (meso), and local (micro) levels. Implications for speech-language pathologists and aphasia service delivery are discussed. An overarching call to action is the need for speech-language pathologists to support a strong and vibrant aphasia community at all levels, so that the voices of people with aphasia can be heard.

Treatment resistant hyperemesis gravidarum in a patient with type 1 diabetes mellitus: neonatal withdrawal symptoms after successful antiemetic therapy with mirtazapine

Here we present the case of a 30-year-old woman with type I diabetes mellitus, preeclampsia and treatment resistant persistent hyperemesis gravidarum in her 25th week of gestation who was successfully treated with the antidepressant mirtazapine (Remergil). Nausea and vomiting resolved within 5 days. After discharge from the hospital in 28 weeks of gestation and discontinuation of the medication on her own initiative a relapse occurred, once again with good response to mirtazapine. The drug was continued until birth. At 34 + 0 weeks a cesarean section was performed due to fetal growth restriction and deteriorating preeclampsia. During the second and fourth day postnatal age the child temporarily developed hyperarousal which could be explained by mirtazapine withdrawal.
