Promoting Early Literacy Using Digital Devices: A Pilot Randomized Controlled Trial.

OBJECTIVE: To determine feasibility and explore effects of literacy promotion using e-books versus board books on the home reading environment, book reading, television use, and child development. METHODS: Randomized controlled trial comparing digital literacy promotion (DLP) using e-books to standard literacy promotion (SLP) using board books among Medicaid-eligible infants. DLP participants received e-books on home digital devices, while SLP participants received board books at well visits between 6 and 12 months of age. Differences in StimQ Read Subscale (StimQ-Read) scores, parent-reported reading and television use, and Bayley Scales of Infant Development-3rd Edition (Bayley-3) scores between groups were assessed using intention-to-treat analysis. RESULTS: A total of 104 Medicaid-eligible infants were enrolled and randomized from 3 pediatric practices. There were no differences in sociodemographic characteristics between groups at baseline. Children in the DLP group initially had lower StimQ-Read scores but showed similar increases in StimQ-Read scores over time as children in the SLP group. Parents in the DLP group reported greater use of digital devices to read or engage their child (65% vs 23%, P < .001) but similar board book reading and television viewing. There were no differences between groups in cognitive or motor scale scores, but DLP participants had marginally lower language scales scores (DLP 85.7 vs SLP 89.7; P = .10) at the 6-month follow-up. CONCLUSIONS/DISCUSSION: Literacy promotion using e-books was feasible and associated with greater e-book usage but no difference in board book reading, television viewing, or home reading environment scores. A potential adverse impact of e-books on language development should be confirmed in future study.

Effects of Early Literacy Promotion on Child Language Development and Home Reading Environment: A Randomized Controlled Trial.

Objective: To determine if early literacy promotion, which consisted of board books and reading promotion beginning with newborns, is more effective than standard literacy promotion beginning at 6 months. Study design: Hybrid type 1 randomized controlled implementation trial of Medicaid-eligible newborns. Prior to 6 months of age, early literacy promotion participants received board books and reading promotion at well visits plus weekly text messages on reading, while standard literacy promotion participants only received weekly text messages on safety. Both groups received board books and reading promotion at well visits after 6 months as part of Reach Out and Read. Measures included proportion who received board books to assess implementation and StimQ Read Subscale (SQRS) scores and Preschool Language Scale-Fifth Edition (PLS-5) scores at 6 and 24 months to assess outcomes. Differences in measures were assessed using intention-to-treat analysis. Results: Of 120 newborns enrolled, most were African American, resided with a single parent, or had a parent with ≤high school education. Overall 82% of early literacy promotion participants received books/counseling at well visits <6 months old. Children in the early literacy promotion arm had greater SQRS scores (11.0 vs 9.4, P = .006) but similar PLS-5 scores at 6 months, but there were no differences in SQRS or PLS-5 scores between groups at 24 months. Conclusions: Implementation of a literacy promotion program early in infancy was associated with richer home reading environments at 6 months but did not improve language development. Although an early literacy program was feasible, additional study may be needed to assess other potential benefits. Trial registration: Clinicaltrials.gov: NCT02713659.

Dementia assessment and management in primary care settings: a survey of current provider practices in the United States.

BACKGROUND: Primary care providers (PCPs) are typically the first to screen and evaluate patients for neurocognitive disorders (NCDs), including mild cognitive impairment and dementia. However, data on PCP attitudes and evaluation and management practices are sparse. Our objective was to quantify perspectives and behaviors of PCPs and neurologists with respect to NCD evaluation and management. METHODS: A cross-sectional survey with 150 PCPs and 50 neurologists in the United States who evaluated more than 10 patients over age 55 per month. The 51-item survey assessed clinical practice characteristics, and confidence, perceived barriers, and typical practices when diagnosing and managing patients with NCDs. RESULTS: PCPs and neurologists reported similar confidence and approaches to general medical care and laboratory testing. Though over half of PCPs performed cognitive screening or referred patients for cognitive testing in over 50% of their patients, only 20% reported high confidence in interpreting results of cognitive tests. PCPs were more likely to order CT scans than MRIs, and only 14% of PCPs reported high confidence interpreting brain imaging findings, compared to 70% of specialists. Only 21% of PCPs were highly confident that they correctly recognized when a patient had an NCD, and only 13% were highly confident in making a specific NCD diagnosis (compared to 72 and 44% for neurologists, both p < 0.001). A quarter of all providers identified lack of familiarity with diagnostic criteria for NCD syndromes as a barrier to clinical practice. CONCLUSIONS: This study demonstrates how PCPs approach diagnosis and management of patients with NCDs, and identified areas for improvement in regards to cognitive testing and neuroimaging. This study also identified all providers' lack of familiarity with published diagnostic criteria for NCD syndromes. These findings may inform the development of new policies and interventions to help providers improve the efficacy of their decision processes and deliver better quality care to patients with NCDs.

The Brain Health Assessment for Detecting and Diagnosing Neurocognitive Disorders.

BACKGROUND/OBJECTIVES: Brief cognitive screens lack the sensitivity to detect mild cognitive impairment (MCI) or support differential diagnoses. The objective of this study was to validate the 10-minute, tablet-based University of California, San Francisco (UCSF) Brain Health Assessment (BHA) to overcome these limitations. DESIGN: Cross-sectional. SETTING: UCSF Memory and Aging Center. PARTICIPANTS: Older adults (N = 347) (neurologically healthy controls (n = 185), and individuals diagnosed with MCI (n = 99), dementia (n = 42), and as normal with concerns (n = 21)). MEASUREMENTS: The BHA includes subtests of memory, executive function and speed, visuospatial skills, and language and an optional informant survey. Participants completed the Montreal Cognitive Assessment (MoCA) and criterion-standard neuropsychological tests. Standardized structural 3T brain magnetic resonance imaging was performed in 145 participants. RESULTS: At a fixed 85% specificity rate, the BHA had 100% sensitivity to dementia and 84% to MCI; the MoCA had 75% sensitivity to dementia and 25% to MCI. The BHA had 83% sensitivity to MCI likely due to AD and 88% to MCI unlikely due to AD, and the MoCA had 58% sensitivity to MCI likely AD and 24% to MCI unlikely AD. The BHA subtests demonstrated moderate to high correlations with the criterion-standard tests from their respective cognitive domains. Memory test performance correlated with medial temporal lobe volumes; executive and speed with frontal, parietal, and basal ganglia volumes; and visuospatial with right parietal volumes. CONCLUSION: The BHA had excellent combined sensitivity and specificity to detect dementia and MCI, including MCI due to diverse etiologies. The subtests provide efficient, valid measures of neurocognition that are critical in making a differential diagnosis.

A Comparison of the Haider Tube-Guard® Endotracheal Tube Holder Versus Adhesive Tape to Determine if This Novel Device Can Reduce Endotracheal Tube Movement and Prevent Unplanned Extubation.

BACKGROUND: Endotracheal tube security is a critical safety issue. We compared the mobility of an in situ endotracheal tube secured with adhesive tape to the one secured with a new commercially available purpose-designed endotracheal tube-holder device (Haider Tube-Guard). We also observed for the incidence of oropharyngeal or facial trauma associated with the 2 tube fixation methods. METHODS: Thirty adult patients undergoing general anesthesia with neuromuscular blockade were prospectively enrolled. Immediately after intubation, a single study author positioned the endotracheal tube tip in the distal trachea using a bronchoscope. Anesthesiologists caring for patients secured the tube in their normal fashion (always with adhesive tape). A force transducer was used to apply linear force, increasing to 15 N or until the principal investigator deemed that the force be aborted for safety reasons. The displacement of the endotracheal tube was measured with the bronchoscope. Any tape was then removed and the endotracheal tube secured with the Haider Tube-Guard device. The linear force was reapplied and the displacement of the endotracheal tube measured. The Haider Tube-Guard device was left in place for the duration of the case. The patient's face and oropharynx were examined for any evidence of trauma during surgery and in the recovery room. On discharge from the postanesthesia care unit, the patient answered a brief survey assessing for any subjective evidence of minor facial or oropharyngeal trauma. RESULTS: Under standardized tension, the endotracheal tube withdrew a mean distance of 3.4 cm when secured with adhesive tape versus 0.3 cm when secured with the Haider Tube-Guard (P <0.001). Ninety-seven percent of patients (29/30) experienced clinically significant endotracheal tube movement (>1 cm) when adhesive tape was used to secure the tube versus 3% (1/30) when the Haider Tube-Guard was used (P <0.001). Thirty percent of patients (9/30) were potentially deemed a high extubation risk (endotracheal tube movement >4 cm) when the endotracheal tube was secured with tape versus 0% (0/30) when secured with the Haider Tube-Guard (P = 0.004). Six patients with taped endotracheal tubes required the traction to be aborted before 15 N of force was achieved to prevent potential extubation as the tape either separated from the face or stretched to allow excessive endotracheal tube movement. None of the patients appeared to sustain any injury from the Haider Tube-Guard device. CONCLUSIONS: The Haider Tube-Guard significantly reduced the mobility of the endotracheal tube when compared with adhesive tape and was well tolerated in our observations.

The effects of informational interventions on household water management, hygiene behaviors, stored drinking water quality, and hand contamination in peri-urban Tanzania.

Safe water storage and hand hygiene have been shown to reduce fecal contamination and improve health in experimental settings; however, triggering and sustaining such behaviors is challenging. This study investigates the extent to which personalized information about Escherichia coli contamination of stored water and hands influenced knowledge, reported behaviors, and subsequent contamination levels among 334 households with less than 5-year-old children in peri-urban Dar es Salaam, Tanzania. One-quarter of the study participants received information about strategies to reduce risk of water- and sanitation-related illness. Respondents in another three study cohorts received this same information, along with their household's water and/or hand-rinse test results. Findings from this study suggest that additional work is needed to elucidate the conditions under which such testing represents a cost-effective strategy to motivate improved household water management and hand hygiene.

Hands, water, and health: fecal contamination in Tanzanian communities with improved, non-networked water supplies.

Almost half of the world's population relies on non-networked water supply services, which necessitates in-home water storage. It has been suggested that dirty hands play a role in microbial contamination of drinking water during collection, transport, and storage. However, little work has been done to evaluate quantitatively the association between hand contamination and stored water quality within households. This study measured levels of E. coli, fecal streptococci, and occurrence of the general Bacteroidales fecal DNA marker in source water, in stored water, and on hands in 334 households among communities in Dar es Salaam, Tanzania, where residents use non-networked water sources. Levels of fecal contamination on hands of mothers and children were positively correlated to fecal contamination in stored drinking water within households. Household characteristics associated with hand contamination included mother's educational attainment, use of an improved toilet, an infant in the household, and dissatisfaction with the quantity of water available for hygiene. In addition, fecal contamination on hands was associated with the prevalence of gastrointestinal and respiratory symptoms within a household. The results suggest that reducing fecal contamination on hands should be investigated as a strategy for improving stored drinking water quality and health among households using non-networked water supplies.
