Caregivers' perspectives of early developmental tele-assessments in challenging circumstances.

BACKGROUND:  Outbreaks, such as the COVID-19 pandemic in 2020, exacerbate barriers to accessing early childhood developmental care. Tele-assessment may serve as an innovative approach to developmental monitoring to overcome service delivery amidst challenging circumstances. It is vital to collect caregivers' perspectives of this potential service delivery method to inform clinical decision making. OBJECTIVES:  This study aimed to determine caregivers' perspectives of interview-based early developmental tele-assessment in a South African context. METHOD:  Thirty caregivers of children (aged birth - 36 months) completed a caregiver-report developmental assessment via a telecommunications platform, as well as an online questionnaire probing their perspectives on the tele-assessment. RESULTS:  Most participants (96.7%, n = 29 out of 30) rated their overall experience of the tele-assessment as positive; however, 53.8% (n = 14 out of 26 that answered the question) indicated that they would additionally still prefer in-person assessment. CONCLUSION:  Tele-assessment appears to be a viable approach for caregivers to access developmental care during circumstances such as COVID-19.Contribution: This study provided valuable insight into a novel approach using interview-based early developmental tele-assessment and the perspectives of caregivers thereof.

Nurses' practices in stroke-related dysphagia in low- and middle-income countries.

BACKGROUND:  Nurses are often required to perform dysphagia screening prior to oral intake by people following stroke. Previous studies report limited knowledge of nurses in identifying symptoms of post-stroke dysphagia. OBJECTIVE:  To explore existing literature regarding nurses' practices and knowledge in the identification and management of post-stroke oropharyngeal dysphagia (OPD) in low- and middle income countries (LMICs). METHOD:  A scoping review was conducted according to the PRISMA-ScR guidelines. Studies were retrieved from PubMed, Scopus, EBSCOhost (CINAHL and Health source: Nursing and Academic edition), Web of Science Core collection, and Cochrane libraries. No time frame was applied, and all included studies were screened according to predefined eligibility criteria. RESULTS:  Eight studies were included from 1 792 initial hits. Studies described nursing practices in acute care pertaining to identification and management of stroke-related dysphagia in LMICs. Increased knowledge was reported in nurses who had greater clinical experience in managing patients with dysphagia. Needs for training relating to dysphagia management and opportunities for interprofessional collaboration with speech-language therapists (SLTs) were identified. Contextual barriers specific to LMICs impacting on optimal nursing management of dysphagia included heavy workloads, staff-shortages and time constraints.Conclusion and contribution: Eight studies described nurses' practices and identified needs for the improvement of nurses' dysphagia care in LMICs. This scoping review highlighted the urgency for further research in dysphagia management that provides creative, contextually relevant solutions for improved protocols and training of health care professionals. Findings may be valuable for the multidisciplinary team involved in post-stroke dysphagia care.

Self-reported Vocal Demands, Perceptions, and Knowledge of Occupational Voice Users in South Africa.

OBJECTIVES: The study aimed to describe daily vocal demands, perceptions and knowledge as reported by occupational voice users. STUDY DESIGN: A descriptive, cross-sectional research design was employed. METHODS: A survey on vocal demands, perceptions and knowledge was distributed to 102 occupational voice users via a snowball sampling technique. RESULTS: Slightly more than half of the participants (55%) reported using their voice for work 36.5 hours a week on average (SD = 15.5, range: 33-40). Participants reported that, on average, their daily voice use is 6.3 hours (SD = 2.7) for work and the majority (81%) reported a decrease in voice quality after work; Three-quarters (75%) also reported vocal fatigue at the end of day. Approximately one-third (33%) reported being exposed to environments where they are expected to shout, scream or cheer loudly. More than half of the participants (61%) reported that they have previously received vocal health education but 40% reported that they felt this training was insufficient. High vocal demands are significantly correlated to an increase in perceived vocal handicap rs = 0.242; (P = 0.018), tiredness of voice rs = 0.270; (P = 0.008), physical discomfort rs = 0.217; (P = 0.038) as well as how occupational voice users experience improvement of symptoms with rest rs = -0.356 (P < 0.001). Other risk factors highlighted by occupational voice users are the ingestion of liquid caffeine, alcohol, and carbonated drinks, smoking or the presence of chronic cough, chronic laryngitis, and gastroesophageal reflux disease. CONCLUSIONS: Occupational voice users are subjected to high daily vocal demands that can be seen to be linked to vocal fatigue, changes in voice quality and vocal symptoms experienced. It is essential that occupational voice users as well as treating clinicians are aware of certain significant predictors of both vocal handicap and vocal fatigue. These findings provide insights for developing strategies for training and cultivating vocal health consciousness and preventive voice care initiatives that focus on occupational voice users in South Africa.

The Effect of Vocal Hygiene Education Programs on Voice Quality in Professional Voice Users: A Systematic Review.

PURPOSE: This study aimed to critically appraise recent peer-reviewed scientific evidence on the effect of vocal hygiene education on voice quality and function directly and indirectly measured by auditory-perceptual, acoustic, and self-report measures in professional voice users. METHOD: A systematic review was conducted utilizing the Preferred Reporting Items for Systematic review and Meta-Analyses Protocols (PRISMA-P) guidelines. Five databases were searched using the keywords "vocal hygiene," "vocal hygiene education," "vocal health," "vocal quality," and "voice quality" with Boolean phrases "AND" and "OR." Twenty-three studies that met the eligibility criteria were included. Scoring was based on the American Speech-Language-Hearing Association's levels of evidence and quality indicators, as well as the Newcastle-Ottawa Scale for assessing the risk of bias. RESULTS: Four studies (17%) linked low awareness of vocal hygiene or insufficient vocal hygiene education to self-reported acute and chronic voice symptoms, as well as a greater perception of voice handicap among professional voice users. Numerous studies (n = 10; 43%) showed that adequate voice training or vocal hygiene education was linked to positive voice outcomes. Six studies (6.26%), however, demonstrated that vocal hygiene education is more effective when combined with direct voice therapy. When vocal hygiene education is presented in isolation, the superiority of a direct voice therapy approach, with or without vocal hygiene education, is seen over a vocal hygiene education program alone (indirect treatment). CONCLUSIONS: Recent literature demonstrates mixed results obtained through auditory-perceptual, acoustic, and self-rating measures on the effects of vocal hygiene instruction on vocal quality and function in professional voice users. However, the compelling positive outcomes presented do warrant implementation of vocal hygiene education programs in combination with direct voice therapy for professional voice users.

Reflux symptoms and vocal characteristics in adults with non-organic voice disorders.

BACKGROUND:  Laryngopharyngeal reflux (LPR) is prevalent and can lead to voice disorders, but its diagnosis is difficult, because of limited correlations between clinical symptoms and organic pathology. Various tools and methods have been explored to aid a diagnosis of LPR. OBJECTIVE:  To investigate associations between reflux symptoms, acoustic-, perceptual-, and physical vocal characteristics, glottal function index (GFI), and vocal handicap index (VHI) in adults with non-organic voice disorders. METHODS:  Data of 51 adults with non-organic voice disorders were collected, using a retrospective cohort explorative research design, at a private ear, nose and throat specialist practice in Gauteng, South Africa. Quantitative outcomes were compared between reflux symptom index (RSI), acoustic characteristics (jitter, shimmer and fundamental frequency [F0]), maximum phonation time, perceptual- (GRBASI) and physical vocal characteristics, GFI and VHI. RESULTS:  The RSI showed positive fair correlations against GFI, VHIP and caffeine intake, indicating an increase in reflux symptoms with higher scores on the various measures. Moderate correlations were also found between GFI and VHIP, grade of hoarseness and jitter, strain and VHIP, strain and VHI total (VHIT) and between Asthenia and jitter. Very strong correlations were found within the various subsections of the VHI as well as between jitter and shimmer and between F0-male and physical symptoms of the VHI (VHIP). CONCLUSION:  Results indicated associations between reflux symptoms, vocal characteristics, the GFI and the VHI. Based on the correlations found these tools used in conjunction could improve clinical diagnosis of LPR. Implications of these findings are promising, but further research is recommended.Contribution: This study contributes to the body of knowledge to support the accurate clinical diagnosis of LPR using subjective measures to determine LPR symptoms, as well as acoustic analysis.

Breastfeeding Outcomes and Associated Risks in HIV-Infected and HIV-Exposed Infants: A Systematic Review.

Purpose: To critically appraise recent literature regarding breastfeeding outcomes and associated risks in HIV-infected (HI) and HIV-exposed (HE) infants, using the Preferred Reporting Items for Systematic review and Meta-Analysis Protocols (PRISMA-P) statement guidelines. Materials and Methods: Five electronic databases were systematically searched to obtain English publications from the last 10 years (2010-2020), pertaining to breastfeeding outcomes and associated risks of HI and HE infants and children. Gray literature sources were also included. Data were extracted according to various data items and were synthesized using thematic synthesis. Results: Of the initial 7,151 sources identified, 42 articles were eligible for final inclusion. The final selection included 19 cohort studies and 2 expert committee reports, classified as gray literature. The remaining 21 studies comprised case-control, cross-sectional, and randomized controlled trial studies. The following themes were identified: breastfeeding outcomes in HI and HE infants, risks for suboptimal breastfeeding, HI and HE infant growth and developmental outcomes, and barriers and facilitators to feeding decisions. Most studies highlighted HE infants' growth and developmental outcomes and did not directly interrogate breastfeeding outcomes. The most prevalent risks for suboptimal breastfeeding were maternal factors affecting decision making for breastfeeding. Conclusions: This systematic review adds to the evidence of breastfeeding in HIV-affected mother-infant dyads. Findings reiterated that exclusive breastfeeding has a positive outcome on growth and development of all infants irrespective of HIV status. The review highlighted a dearth of research on breastfeeding outcomes of HI and HE infants. Large-scale prospective comparative studies should profile breastfeeding and developmental outcomes of infants with HIV infection or exposure and antiretroviral treatment exposure to enable early identification and intervention for this vulnerable population in low-income settings.

Developmental Risks in Vulnerable Children from a Low-Income South African Community.

OBJECTIVE: To describe the developmental risks, and its influence, in young children from a low-income South African community. METHOD: An exploratory, cross-sectional research study design was employed. Developmental screening was conducted during home visits with 126 caregivers and children between 0 and 42 months of age from a low-income South African community. Children who failed the rescreen were referred for diagnostic assessment. A binomial logistic regression was used to determine the effect of developmental risks on developmental outcomes. RESULTS: Seventy-three percent of children screened were identified with a possible developmental delay (n = 59) according to caregiver-report using the PEDS tools. The regression model was statistically significant (χ2 (3) = 34.902, p < 0.001) with exposure to multiple languages (p < 0.05; odds ratio 3.810, CI 1.2-12.4) most indicative of potential developmental delay. Older children (19-42 months) were also more at risk of developmental delay (p < 0.001) than younger children (0-18 months). CONCLUSIONS FOR PRACTICE: Healthcare professionals serving these vulnerable populations should create awareness amongst caregivers about the effect of developmental risks, in particularly multiple language exposure, on development.

mHealth developmental screening for preschool children in low-income communities.

Children are often only identified with a developmental delay when they enter primary school due to developmental delays hindering academic progress. Detection of at-risk children in low-income communities is typically unavailable due to several challenges. This study validated an mHealth-based developmental screening tool as a potential time- and cost-effective way of delivering services for preschool children. This cross-sectional within-subject study screened 276 preschool children from low-income communities using the mHealth Parents' Evaluation of Developmental Status (PEDS) tools. The mHealth PEDS tools' performance was then evaluated by comparing caregiver concerns according to the PEDS tools with results obtained using a reference standard assessment tool, the Vineland-3. The mHealth PEDS tools identified 237 (85.9%) of children at risk of developmental delay compared to 80.1% (n = 221) of children identified with a developmental delay using the Vineland-3. Sensitivity of the PEDS tools was high (92.6%) with low specificity (22.5%) using US standardised criteria. Literacy skills were found to be most delayed, according to the PEDS: DM (89.3%; n = 142) and Vineland-3 (87.1%; n = 134). Low specificity of the prescribed criteria may require the implementation of adapted referral criteria within low socio-economic status (SES) settings. The mHealth PEDS tools may still be valuable for preschool developmental surveillance of children within low SES settings. It is recommended, however, that children who are identified with a developmental concern undergo a second screen to reduce false positives.

Early Childhood Development Risks and Protective Factors in Vulnerable Preschool Children from Low-Income Communities in South Africa.

Age-appropriate early childhood development is greatly influenced by exposure to various mediating and moderating factors. Developmental outcomes cannot be viewed in isolation, but by considering the interaction of the various risks and protective factors that influence early child development. A non-experimental, cross-sectional research design was employed. Data was collected in a low-income community in Gauteng, South Africa. Caregivers with children (n = 276) between the ages of 3 years and 6 years 11 months (mean 51.57 months; SD ± 12.4) whose children were in a preschool were invited to participate in the research study. Participants were divided into two groups, children with developmental delays and children without a developmental delay. The study sample included high risk, vulnerable preschool children, with a developmental delay prevalence of 80.1% (221/276). Families included were exposed to an average of five (SD ± 1.86) environmental and/or biological risks. According to a logistic regression model, three factors were significantly associated with increasing resilience amongst children with no developmental delay: living with both parents (p < 0.031, OR 4.5, 95% CI 1.2-17.2), caregivers having at least completed Grade 8 to 12 (p < 0.027, OR 11.9, 95% CI 1.4-10.5) and parents being married (p < 0.023, OR 5.1, 95% CI 1.3-20.9). Important protective factors in low-income communities like caregiver education, living with both parents and parental marriage can inform public health messaging and other population-based interventions to support early childhood development.

Anionic Fischer-type carbene complexes as bidentate (N,O) ligands.

New polynuclear complexes, (L1)3M2 [M2 = Cr(III) (4a,4b), Fe(III) (5), Co(III) (8)], (L1)2M2(L2)2 [M2 = Co(II) (7), Ni(II) (9)], (L1)2M2(O)L2 [M2 = V(IV) (6)] and L1M2Cp2 [M2 = Ti(III) (10)] with L1 = (CO)5M1=C[C=NC(CH3)=CHS](O-)(M1 = Cr or W) and L2 = 4-methylthiazole or THF, are described. The molecular structures of these complexes determined by X-ray diffraction show that the Fischer-type carbene complexes act as bidentate ligands towards the second metal centre, coordinating through C(carbene)-attached O-atoms and imine N-atoms of the thiazolyl groups to form five-membered chelates with the oxygen atoms in the mer configuration. Isostructural complexes have similar characteristic band patterns in their far-IR spectra. Cyclic voltammetry of selected complexes reveals the oxidation of the carbene complex ligand between 1.01 and 1.29 V. Oxidation of the central metal (M2) takes place at 0.56 and 0.86 V for 7 and 9, respectively. Three stepwise reductions of Cr(III) to Cr(0) occur for 4a and 4b in the region -0.51 to -1.58 V. These new ligand types and other variants thereof should find application in ligand design with the first metal -- and other ligands attached thereto -- in the carbene complex ligand, playing an important role.
