A systematic scoping review of speech and language therapists’ public health practice for early language development

Abstract

Background

There have been calls for speech and language therapists (SLTs) to work within a public-health framework to support language development. Innovative practice is reported, but the range of services remains unknown. Furthermore, the potential impact of public health practice in speech and language therapy on early child development is also currently unknown. A new method in SLT research, systematic scoping reviews enable greater breadth of focus than traditional systematic reviews when identifying innovative practice.

Aim

To report scope and critically appraise evidence of family-focused health-promotion practice for early language development in this area.

Methods & Procedures

Using the Cochrane Public Health Group scoping review framework, data from reports of health-promotion practice with families of children aged 0–3 years were extracted and critically appraised on service delivery, information, reach and evaluation.

Main contribution

Group-based service delivery was the most popular form of service delivery. There were limited reports on the information given in services and on their reach. Questionnaires were the most popular reported evaluation method. Quality of evaluations was poor due to lack of replicability and experimental control in the studies reported.

Conclusions & Implications

This method of systematic review has highlighted the scope of health-promotion practice in speech and language therapy and also demonstrated the lack of evidence for its effectiveness on child language development. It is argued that systematic scoping reviews are valuable for scoping innovative practice in areas where either there is a lack of robust evidence or there is a high level of heterogeneity in practice or evaluation. To support clinician appraisal of available evidence, recommendations are given for development of questionnaire appraisal and for categorization of evidence levels on summary databases.

Change in receptive vocabulary from childhood to adulthood: associated mental health, education and employment outcomes

Abstract

Background

Population-based studies have found that early language delays are associated with poorer long-term outcomes in adolescence and adulthood. Few studies have explored the influence of change in language ability over time on adult outcomes.

Aim

To examine the educational, vocational and mental health outcomes for adults accounting for different vocabulary developmental profiles over a 16-year period.

Methods & Procedures

A total of 1914 participants of the Mater-University of Queensland Study of Pregnancy (MUSP) were categorized into four groups based on their vocabulary skills at 5 and 21 years: (1) persistently good (n = 1679), (2) persistently poor (n = 33), (3) improved (n = 160), and (4) deteriorated (n = 42). The associations between vocabulary group and educational, vocational, and mental health outcomes at 21 years were investigated.

Outcomes & Results

Adults with deteriorated and persistently poor vocabulary skills were less likely to have completed secondary school; with the improved, deteriorated and persistently poor groups being less likely to be engaged in education, employment or training at the 21-year follow-up, compared with the persistently good group. Adults with deteriorated performance were at an increased risk of affective disorders, as well as substance and alcohol abuse/misuse.

Conclusions & Implications

These findings provide evidence that impaired vocabulary skills in adulthood, regardless of whether the deficit was acquired early or later, are associated with adverse outcomes. Clinicians and educators need to be aware of these adversities and ensure they are supporting children and adolescents in whom language difficulties exist or emerge so as to prevent poor long-term outcomes from occurring.

The German Intelligibility in Context Scale (ICS-G): reliability and validity evidence

Abstract

Background

In 2012 the Intelligibility in Context Scale (ICS) was published as a parent-report screening assessment that considers parents’ perceptions of their children's functional intelligibility with a range of communication partners that differ in levels of authority and familiarity in real-life situations. To date, the ICS has been translated into 60 languages (including German).

Aims

To evaluate the psychometric properties of the German translation of the ICS ( = ICS-G), especially its reliability and validity, using four objective measures of speech sound disorder (SSD) severity: percentage of consonants correct (PCC); percentage of initial consonants correct (PICC); percentage of vowels correct (PVC); and percentage of phonemes correct (PPC).

Methods & Procedures

Children who were typically developing (TD) and children with SSD (n = 181; 90 males, 81 females; mean age = 4.18 years, SD = 0.79 years, range = 3;0–5;11 years) were recruited through 13 kindergartens and 15 speech–language pathologists (SLPs) in Germany. All children's parents completed the ICS-G. To obtain an insight into the severity of SSD (n = 30), children's speech skills were assessed with PLAKSS-II. For the analysis of test–retest reliability the ICS-G was re-administered with a subsample of parents (n = 36) after 1 week.

Outcomes & Results

The ICS-G had high internal consistency (α = .95, p < .001) and high test–retest reliability (r = .998, p < .001). The ICS-G total scores and item scores for both samples showed significant correlations, indicating good construct validity. Analyses revealed low but significant correlations with external factors (e.g., age, social class). Criterion validity was established through significant correlations between the ICS-G and scores for PCC (r = .43), PICC (r = .43), PVC (r = .62) and PPC (r = .47). The discriminatory ability of the ICS-G was indicated by significantly higher mean scores for the TD group (mean = 4.49, SD = 0.47) than the SSD group (mean = 3.97, SD = 0.63).

Conclusions & Implications

The overall good psychometric properties of the ICS-G support its use by SLPs for clinical and research purposes with German-speaking children.

Prevalence and socio-demographic correlates of physical activity levels among South African adults in Cape Town and Mount Frere communities in 2008-2009

Background: Physical activity has been linked to reduced risk of various cardiometabolic disease, cancer, and premature mortality. We investigated the prevalence and socio-demographic correlates of physical activity among adults in urban and rural communities in South Africa. Methods: This was a cross-sectional survey comprising 1733 adults aged ≥35 years from the Cape Town (urban) and Mount Frere (rural) sites of the Prospective Urban Rural Epidemiology study. Physical activity was assessed using the validated International Physical Activity Questionnaire. Multinomial logistic regressions were used to relate physical activity with socio-demographic characteristics. Results: Overall, 74% of participants engaged in moderate-to-vigorous physical activity. In the adjusted regression models, women were 34% less likely to engage in vigorous physical activity (OR =0.66, 95%-CI = 0.47-0.93). Physical activity decreased with age, varied with marital status, education and occupation, always in differential ways between urban and rural participants (all interactions p ≤ 0.047). For instance, in urban settings, those with secondary education were more likely to engage in moderate physical activity (OR = 2.06, 95%-CI = 1.08-3.92) than those with tertiary education. Single people were more likely to engage in high physical activity (OR = 2.10, 95%-CI = 1.03-4.28) than divorced. Overall, skilled participants were more likely to engage in vigorous physical activity (OR = 2.07, 95%-CI = 1.41-3.05) driven by significant effect in rural area (OR = 2.70, 95%-CI = 1.51-4.83). Urban participants were more likely to engage in moderate physical activity (OR = 1.67, 95%-CI = 1.31-2.13) than rural participants. Conclusions: To prevent chronic diseases among South Africans, attention should be paid to specific policies and interventions aimed at promoting PA among young adults in rural and urban setting, and across the social-economic diversity.

Outcome after protected full weightbearing treatment in an orthopedic device in diabetic neuropathic arthropathy (Charcot arthropathy): a comparison of unilaterally and bilaterally affected patients

Background: Charcot neuropathic arthropathy (CN) is a chronic, progressive, destructive, non-infectious process that most frequently affects the bone architecture of the foot in patients with sensory neuropathy. We evaluated the outcome of protected weightbearing treatment of CN in unilaterally and bilaterally affected patients and secondarily compared outcomes in protected versus unprotected weightbearing treatment. Methods: Patient records and radiographs from 2002 to 2012 were retrospectively analyzed. Patients with Type 1 or Type 2 diabetes with peripheral neuropathy were included. Exclusion criteria included immunosuppressive or osteoactive medication and the presence of bone tumors. Ninety patients (101 ft), mean age 60.7 ± 10.6 years at first diagnosis of CN, were identified. Protected weightbearing treatment was achieved by total contact cast or custom-made orthosis. Ulcer, infection, CN recurrence, and amputation rates were recorded. Mean follow-up was 48 (range 1–208) months. Results: Per the Eichenholtz classification, 9 ft were prodromal, 61 in stage 1 (development), 21 in stage 2 (coalescence) and 10 in stage 3 (reconstruction). Duration of protected weightbearing was 20 ± 21 weeks and 22 ± 29 weeks in patients with unilateral and bilateral CN, respectively. In bilaterally affected patients, new ulcers developed in 9/22 (41%) feet. In unilaterally affected patients, new ulcers developed in 5/66 (8%) protected weightbearing feet and 4/13 (31%) unprotected, full weightbearing feet (p = 0.036). The ulceration rate was significantly higher in bilaterally versus unilaterally affected patients with a protected weightbearing regimen (p = 0.004). Soft tissue infection occurred in 1/13 (8%) unprotected weightbearing feet and 1/66 (2%) protected weightbearing feet in unilaterally affected patients, and in 1/22 (4%) protected weightbearing feet of bilaterally affected patients. Recurrence and amputation rates were similar across treatment modalities. Conclusions: Bilateral CN results in significantly more ulcers than unilateral CN and leads to slightly higher soft tissue infections. Protected weightbearing in an orthopedic device can reduce the risk for complications in acute CN of the foot and ankle.

Percutaneous CT-fluoroscopic–guided radioisotope seed placement for the management of adenoid cystic carcinoma of the trachea

Publication date: Available online 28 December 2016
Source:Brachytherapy
Author(s): Stephen Doggett, Shigeru Chino, Todd Lempert, Jay Federhart
PurposeTracheal and paratracheal malignancies present challenges in radiotherapeutic management due to their proximity to sensitive structures, central location, and because of the potential for catastrophic radiation induced fistula. The use of external beam radiation therapy and intraluminal brachytherapy has a limited number of reports in the literature. We have searched for a technique for treating tracheal and paratracheal malignancies allowing application of a high dose of radiation while minimizing dose to normal tissues. Our group has considerable experience in the use of percutaneous CT-guided radioisotope seed implants for intrathoracic malignancies. We have previously reported our technique for percutaneous CT-fluoroscopic–guided radioisotope seed implants in the management of thoracic malignancies. We have now treated several tracheal and paratracheal malignancies with our technique and report our results here. This is to our knowledge the first report of treatment of tracheal malignancy with CT-guided permanent seed implant.Methods and MaterialsThree patients with tracheal adenoid cystic carcinoma were implanted with ¹⁰³Pd under CT-fluoroscopic guidance utilizing percutaneous approach.ResultsAll patients tolerated the procedure well, and at 9-month average followup, all show disease regression, symptom improvement, and no sign of toxicity.ConclusionsWe believe this to be the first published series on CT-directed permanent seed brachytherapy for tracheal malignancies. Review of PubMed literature to 1990 discloses no prior writings on the use of permanent seed implantation for tracheal cancers. Tracheal malignancies provide a vexing radiation therapy challenge to stay within the therapeutic window. CT-directed permanent seed brachytherapy allows a high dose to be delivered to the tumor with a rapid falloff to the surrounding tissues. Short-term results from seed implant are excellent. Our 3 patients responded well in the short term to permanent seed brachytherapy with no chronic side effects and with reduction or relief of cough and pain. CT-fluoro–guided permanent seed implantation is an effective and low morbidity treatment for tracheal malignancies. Long-term followup is needed to further elucidate durability of response and toxicity.

A directional 103Pd brachytherapy device: Dosimetric characterization and practical aspects for clinical use

Publication date: Available online 28 December 2016
Source:Brachytherapy
Author(s): Mark J. Rivard
PurposeA brachytherapy (BT) device has been developed with shielding to provide directional BT for preferentially irradiating malignancies while sparing healthy tissues. The CivaSheet is a flexible low-dose-rate BT device containing CivaDots with ¹⁰³Pd shielded by a thin Au disk. This is the first report of a clinical dosimetric characterization of the CivaSheet device.Methods and MaterialsRadiation dose distributions near a CivaDot were estimated using the MCNP6 radiation transport code. CivaSheet arrays were also modeled to evaluate the dose superposition principle for treatment planning. The resultant data were commissioned in a treatment planning system (TPS) (VariSeed 9.0), and the accuracy of the dose superposition principle was evaluated for summing individual elements comprising a planar CivaSheet.ResultsThe dose-rate constant (0.579 cGy/h/U) was lower than for ¹⁰³Pd seeds due to Au L-shell x-rays increasing the air-kerma strength. Radial dose function values at 0.1, 0.5, 2, 5, and 10 cm were 1.884, 1.344, 0.558, 0.088, and 0.0046, respectively. The two-dimensional anisotropy function exhibited dramatic reduction between the forward (0°) and rearward (180°) directions by a factor of 276 at r = 0.1 cm, 24 at r = 1 cm, and 5.3 at r = 10 cm. This effect diminished due to increasingly scattered radiation. The largest gradient in the two-dimensional anisotropy function was in contact with the device at 92° due to the Au disk shielding. TPS commissioning and dose superposition accuracies were typically within 2%.ConclusionsSimulations of the CivaDot yielded comprehensive dosimetry parameters that were entered into a TPS and deemed acceptable for clinical use. Dosimetry measurements of the CivaSheet are also of interest to the BT community.
