Sustainable Delivery of Speech-Language Therapy Services in Small Island Developing States Using Information and Communication Technology – A Study of the Maldives

Small Island Developing States (SIDS), a subgroup of Majority world countries, face complex challenges providing equitable access to speech-language therapy (SLT) services. Increasing use of information and communication technology (ICT) to enhance SLT services is seen in the Minority world. This study explored the potential of using ICT to provide sustainable SLT services in one SIDS, the Maldives. A mixed method approach was used integrating data from (a) 21 online documents, (b) interview with an ICT official, and (c) surveys of 13 island councillors and 73 parents of children with communication difficulties. Almost 100% of the population had access to mobile phones and mobile broadband internet. Most parents were active and frequent ICT users. The government provided financial aid for people with disabilities which could be utilised to access ICT for services. Asynchronous service delivery using accessible ICT and parents as agents of service delivery can potentially enhance SLT services

Dietary vitamin, mineral and herbal supplement use: a cross-sectional survey of before and during pregnancy use in Sydney, Australia.

AIM: To describe use of dietary vitamin, mineral and herbal supplements before and during pregnancy. METHODS: Pregnant women attending antenatal care at two tertiary Sydney hospitals between January and March 2014 completed an anonymous survey. Information on general maternal and pregnancy characteristics and the use of dietary and herbal supplements, including type, duration, and sources of information was collected. Frequency and contingency tabulations were performed. RESULTS: 612 women agreed to participate (91% response rate). 23 were excluded due to incomplete data. Of 589 women included in the analysis, the mean gestational age at the time of survey was 28.5 weeks (SD 8.3), 55% had no children, and 67% were tertiary educated. Overall 62.9% of women reported taking a multivitamin (MV) and/or folic acid (FA) supplement in the 3 months pre-pregnancy. At the time of the survey 93.8% of women were taking at least one supplement (median 2, range 1-13). During pregnancy 79.1% of women were taking MVs, including 59.2% taking MV only and 19.9% taking MV and FA. The 5 most common supplements outside of a MV were FA (31%), iron (30%), vitamin D (23%), calcium (13%) and fish oil (12%). CONCLUSION: Use of folic acid and MVs and other supplements during and pre-pregnancy is relatively high, although pre-pregnancy FA supplementation rates could still be improved. Further research on the actual dosages and dietary intakes consumed are needed to examine whether pregnant women have adequate intake of nutrients, regardless of supplement use.NHMR

Iron supplement use in pregnancy – are the right women taking the right amount?

Objectives: To examine the prevalence and determinants of iron supplement use and the amount of iron consumed from iron-containing supplements. Methods: A cross-sectional survey was performed in antenatal clinics in two tertiary hospitals in Sydney, Australia between January and March 2014. Results: Of 612 (91% response rate) pregnant women, 589 with complete data were analysed. The overall prevalence of iron-containing supplement use was 88.0%, of which 70.1% was MV only, 7.2% was iron-only and 22.2% was both. Use of iron-containing supplements was associated with increased gestational age, a diagnosis of anaemia or iron deficiency (ID) in the current pregnancy and pre-pregnancy use of an iron-containing supplement. Several risk factors for ID or anaemia such as on-red meat eating and previous miscarriage were not associated with current iron supplement use. About 65% of women diagnosed with ID, and 62.3% of women diagnosed with anaemia were taking an iron-only supplement, with or without a MV. The proportion of women consuming low (<30), preventative (30-99) and treatment (≥100) mg/day doses were 36.8%, 45.4%, and 17.8%, respectively. Only 46.7% of women diagnosed with ID were taking ≥100 mg/day iron from supplements, while 23.3% were taking <30 mg/day. Conclusion: Women are consuming varying doses of iron and some high-risk women are taking inadequate doses of iron to prevent or treat ID or iron deficiency anaemia. Healthcare professionals are best positioned to advise women on iron supplement use in pregnancy and should educate women individually about the type and dose of supplement best suited to their needs.NHMR

The mechanical performance of sugar palm fibres (Ijuk) reinforced phenolic composites

Sugar palm fibres are one of the natural fibres which have many features and need further study to understand their properties. The aim of this work is to investigate the flexural, compressive and impact properties of sugar palm fibres reinforced phenolic composites. Sugar palm fibres were used as a filler (particle size 150 μm) and with loading of 0, 10, 20, 30, and 40 vol.%. The fibres were treated by sea water and then fabricated into composites by hot press technique. Flexural, compressive, and impact tests were carried out as per ASTM D790, ASTM D695-08a, and ASTM D256 standards, respectively. Scanning electron microscopy (SEM) was used to investigate the morphology and the interfacial bonding of the fibres-matrix in composites. The results show that the mechanical properties of the composites improve with the incorporation of fibres. The composite of 30 vol.% particle loading exhibit optimum values which are 32.23 MPa, 61.66 MPa, and 4.12 kJ/m2 for flexural, compressive, and impact strength, respectively. This was because good compatibility of fibre-matrix bonding. Consequently, sugar palm fibre is one of the prospective fibres and could be used as a potential resource to reinforcement polymer composite

Ginseng and ginkgo biloba effects on cognition as modulated by cardiovascular reactivity: a randomised trial

Background There is some evidence to suggest that ginseng and Ginkgo biloba can improve cognitive performance, however, very little is known about the mechanisms associated with such improvement. Here, we tested whether cardiovascular reactivity to a task is associated with cognitive improvement. Methodology/Principal findings Using a double-blind, placebo controlled, crossover design, participants (N = 24) received two doses of Panax Ginseng (500, 1000 mg) or Ginkgo Biloba (120, 240 mg) (N = 24), and underwent a series of cognitive tests while systolic, diastolic, and heart rate readings were taken. Ginkgo Biloba improved aspects of executive functioning (Stroop and Berg tasks) in females but not in males. Ginseng had no effect on cognition. Ginkgo biloba in females reversed the initial (i.e. placebo) increase in cardiovascular reactivity (systolic and diastolic readings increased compared to baseline) to cognitive tasks. This effect (reversal) was most notable after those tasks (Stroop and Iowa) that elicited the greatest cardiovascular reactivity during placebo. In males, although ginkgo also decreased cardiovascular readings, it did so from an initial (placebo) blunted response (i.e. decrease or no change from baseline) to cognitive tasks. Ginseng, on the contrary, increased cardiovascular readings compared to placebo. Conclusions/Significance These results suggest that cardiovascular reactivity may be a mechanism by which ginkgo but not ginseng, in females is associated with certain forms of cognitive improvement

Vitamin D insufficiency in COVID-19 and influenza A, and critical illness survivors: a cross-sectional study

Objectives: The steroid hormone vitamin D has roles in immunomodulation and bone health. Insufficiency is associated with susceptibility to respiratory infections. We report 25-hydroxy vitamin D (25(OH)D) measurements in hospitalised people with COVID-19 and influenza A and in survivors of critical illness to test the hypotheses that vitamin D insufficiency scales with illness severity and persists in survivors. Design: Cross-sectional study. Setting and participants: Plasma was obtained from 295 hospitalised people with COVID-19 (International Severe Acute Respiratory and emerging Infections Consortium (ISARIC)/WHO Clinical Characterization Protocol for Severe Emerging Infections UK study), 93 with influenza A (Mechanisms of Severe Acute Influenza Consortium (MOSAIC) study, during the 2009–2010 H1N1 pandemic) and 139 survivors of non-selected critical illness (prior to the COVID-19 pandemic). Total 25(OH)D was measured by liquid chromatography-tandem mass spectrometry. Free 25(OH)D was measured by ELISA in COVID-19 samples. Outcome measures: Receipt of invasive mechanical ventilation (IMV) and in-hospital mortality. Results: Vitamin D insufficiency (total 25(OH)D 25–50 nmol/L) and deficiency (<25 nmol/L) were prevalent in COVID-19 (29.3% and 44.4%, respectively), influenza A (47.3% and 37.6%) and critical illness survivors (30.2% and 56.8%). In COVID-19 and influenza A, total 25(OH)D measured early in illness was lower in patients who received IMV (19.6 vs 31.9 nmol/L (p<0.0001) and 22.9 vs 31.1 nmol/L (p=0.0009), respectively). In COVID-19, biologically active free 25(OH)D correlated with total 25(OH)D and was lower in patients who received IMV, but was not associated with selected circulating inflammatory mediators. Conclusions: Vitamin D deficiency/insufficiency was present in majority of hospitalised patients with COVID-19 or influenza A and correlated with severity and persisted in critical illness survivors at concentrations expected to disrupt bone metabolism. These findings support early supplementation trials to determine if insufficiency is causal in progression to severe disease, and investigation of longer-term bone health outcomes

Speech language therapy services for children in Small Island Developing States – the situation in the Maldives

Speech-language therapists (SLT) support people with communication difficulties to exercise their right to communicate. Yet, children in Majority world countries face great obstacles to accessing these services. Vulnerable countries within the Majority world, such as Small Island Developing States (SIDS) face complex challenges due to particular environmental, social and economic vulnerabilities. Access to services is unlikely to improve in underserved communities unless service delivery approaches take the context into consideration. This preliminary study used mixed methods to explore environmental, social and economic conditions affecting equitable access to SLT services for children in one SIDS, the Maldives. Forty publicly available online documents were analyzed, and online surveys were conducted with 107 teachers and 73 parents of children with communication difficulties to examine the conditions that affect equitable access to SLT services in the Maldives. This data revealed three major characteristics of the Maldivian context: (1) Barriers related to geography, dispersed population and transport, (2) Inadequacy of current services to meet needs, and (3) Significant need to minimize costs
