Examining the Use of a Rest-Activity Ratio in a Pediatric Rehabilitation Setting.

OBJECTIVE: To examine the relationship between an estimate of sleep-wake regulation derived from actigraphy and determine whether it would be sensitive to neurocognitive dysfunction associated with acquired brain injury (ABI) in a pediatric rehabilitation sample. DESIGN: Cross-sectional design. SETTING: Inpatient pediatric rehabilitation facility. PARTICIPANTS: A sample (N=43) of 31 males (72.1%) and 12 females (27.9%) admitted to a pediatric rehabilitation hospital wore an actigraph (wrist accelerometer) for 1 week. Participant ages ranged from 8 to 17 years (mean, 13.1y; SD, 2.7y). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Raw actigraphy activity counts in 1-minute epochs were used to derive a rest-activity ratio over each 24-hour period; a 5-day average value was calculated for Monday through Friday. Brain injury status was derived through medical record review, resulting in the formation of 3 groups: traumatic brain injury (n=14), nontraumatic brain injury (n=16), and a non-ABI control group (n=13). Functional status was measured using FIM for children (WeeFIM) Cognitive and Motor scores extracted from the medical records. RESULTS: Unadjusted models showed a significant main group effect for brain injury status (P=.012). Compared with controls, the rest-activity ratio was significantly lower in both the traumatic brain injury (P=.005), and nontraumatic brain injury (P=.023) groups. However, the main group effect was no longer significant in an adjusted model controlling for WeeFIM Cognitive and WeeFIM Motor scores at admission. In the context of the adjusted model, there was a significant relationship between the rest-activity ratio and WeeFIM Cognitive scores at admission. CONCLUSIONS: Individuals with lower functional status at admission, especially in the cognitive domain, had lower rest-activity ratios, suggesting poorer sleep-wake regulation. Similar to findings in adults with ABI, this ratio may have utility in tracking sleep-wake regulation in the pediatric rehabilitation setting. Future studies should investigate sensitivity to change over the course of recovery and responsiveness to clinical interventions to improve sleep.

Evaluating a multidisciplinary inpatient program for youth with type 1 diabetes mellitus.

Among youth with type 1 diabetes mellitus (T1D), older adolescents demonstrate more dysglycemia and less adherence to disease management. Poor disease management during this time of development can continue into adulthood, perpetuating the economic and health burden to the individual, health care system and society. This study aimed to evaluate the effectiveness of an inpatient multidisciplinary approach to treating youth with T1D. All T1D admissions to the 4 week Chronic Illness Management Program (CIMP) between 1 January 2016 and 31 December 2017 were eligible for inclusion. Data related to physiological and psychosocial outcomes were compared between admission and discharge. Follow-up data, including hemoglobin A1c (HbA1c), psychosocial measures, and health care utilization, were collected at 3, 6, and 12 months after discharge to assess sustained changes. Fifty-seven T1D admissions were included in the sample. There was a significant reduction in mean HbA1c from admission (11.1%/98 mmol/mol) to discharge (9.1%/76 mmol/mol). Patients also demonstrated significant improvements in all psychosocial outcome measures. Improvements in HbA1c were sustained at 3 months follow-up; however, average values returned to baseline by 6 months follow-up. In contrast to preadmission history, the majority of the sample reported reduced crisis health care utilization 1 year after discharge. The inpatient setting provides an intensive treatment model for diabetes management that promotes sustainable behavior change 3 months after discharge. While additional community supports are needed for long-term improvement, this program model may benefit patients who have been unable to manage their diabetes with outpatient treatment and therapy alone.

Inpatient length of stay moderates the relationship between payer source and functional outcomes in pediatric brain injury.

OBJECTIVE: To examine the extent to which race/ethnicity, length of rehabilitation hospital stay (LOS), and payer source contribute to functional status following inpatient rehabilitation in children with acquired brain injury (ABI). DESIGN: Retrospective cohort study from a pediatric rehabilitation hospital including 485 individuals with ABI. METHODS: Functional Independence Measure for Children (WeeFIM) scores were transformed into age-corrected Developmental Functional Quotients (DFQ) to examine the effects of race/ethnicity, LOS, and payer source (public insurance vs. private) on functional outcomes while controlling for year of admission, admission DFQ, time to rehabilitation, age, and brain injury aetiology. RESULTS: Discharge DFQ scores tended to be lower for children with public insurance as well as those with longer LOS. There was no main effect of race/ethnicity, but a significant interaction effect for payer source×LOS (p < .001) was found. Further breakdown of the interaction showed lower discharge DFQ scores for children with public insurance primarily when LOS exceeded 28 days (p = .001). CONCLUSION: Children with ABI who have both public insurance and LOS beyond 4 weeks tend to have poorer functional outcomes after inpatient rehabilitation. Because all children were receiving services at the same facility, payer source may be functioning as a proxy for other sociodemographic factors.

Blood folate concentrations among women of childbearing age by race/ethnicity and acculturation, NHANES 2001-2010.

Hispanic women have higher rates of neural tube defects and report lower total folic acid intakes than non-Hispanic white (NHW) women. Total folic acid intake, which is associated with neural tube defect risk reduction, has been found to vary by acculturation factors (i.e. language preference, country of origin, or time spent in the United States) among Hispanic women. It is unknown whether this same association is present for blood folate status. The objective of this research was to assess the differences in serum and red blood cell (RBC) folate concentrations between NHW women and Mexican American (MA) women and among MA women by acculturation factors. Cross-sectional data from the 2001-2010 National Health and Nutrition Examination Survey (NHANES) were used to investigate how blood folate concentrations differ among NHW or MA women of childbearing age. The impact of folic acid supplement use on blood folate concentrations was also examined. MA women with lower acculturation factors had lower serum and RBC folate concentrations compared with NHW women and to their more acculturated MA counterparts. Consuming a folic acid supplement can minimize these disparities, but MA women, especially lower acculturated MA women, were less likely to report using supplements. Public health efforts to increase blood folate concentrations among MA women should consider acculturation factors when identifying appropriate interventions.

Experiences of patients, parents, and healthcare professionals in the process of transitioning from hospital to community after inpatient pediatric rehabilitation among children with special health care needs.

PURPOSE: Children with Special Health Care Needs (CSHCN) may experience disruptions in education due to extended hospitalizations. The purpose of this study was to describe how CSHCN experience educational supports during inpatient rehabilitation and identify the ongoing challenges when planning to return to school. MATERIALS AND METHODS: Semi-structured focus groups were conducted with parents (n = 12), former patients (n = 20), and rehabilitation professionals (n = 8). RESULTS: Through qualitative thematic analysis based on descriptive phenomenology, we developed three themes: 1) Inpatient educational support such as instruction and schoolwork helped reduce the learning loss during hospitalization. However, these supports were sometimes complicated by lags in school approvals and challenges in coordination between systems. 2) Transition planning involved establishing necessary services to support CSHCN's educational and healthcare needs at school re-entry. However, families reported limited information and guidance as key barriers. 3) Dynamic courses of school re-entry required continued support after discharge. The participants recommended that reassessment and adjustment of transition plans were often necessary to account for evolving developmental and educational needs but were not always received. CONCLUSIONS: There is an ongoing need to improve communication between clinicians and educators, information for families, and long-term follow-up on the changing educational needs for CSHCN after rehabilitation.

School re-entry after extended hospitalization is challenging for children with special health care needs (CSHCN) due to school disruption, social disconnection, and change in functional abilities.The hospital-to-school transition processes include inpatient educational programs during hospitalization, pre-discharge transition planning, and the subsequent implementation and adjustment of transition plans to facilitate individualized school re-entry.Key areas in need of improving school re-entry include coordination between the hospital and school about rehabilitation and educational goals and information provided to families about transition processes, particularly for newly acquired health conditions.A common need expressed by parents and CSHCN is to simplify and accelerate the process to establish services that support children's educational and healthcare needs.

Transfer Timing and the Length of Medication Weaning for Neonatal Opioid Withdrawal Syndrome.

OBJECTIVE: Many infants with neonatal opioid withdrawal syndrome (NOWS) from prenatal exposure to opioids require transfer to a pediatric inpatient unit for medication weaning. The purpose of this study is to assess the difference in the duration of medication weaning between infants transferred by day of life (DOL) 14 versus later (DOL 15 and after) to a tertiary care setting for pharmacological and nonpharmacological management of NOWS. METHODS: This single-site retrospective cohort study uses medical chart data from infants with NOWS transferred to specialized care between May 2016 and June 2021 (n = 87). The primary outcome is length of medication weaning, calculated as the number of days between transfer from the NICU to a tertiary care setting and the cessation of pharmacotherapy. RESULTS: The majority of the infants in this sample are transferred from acute to tertiary care after DOL 15 (62% versus 38% by DOL 14). The predicted number of days to wean is 14.2 among those infants transferred by DOL 14, whereas the duration of weaning is 6.6 days longer among the later transfer group (20.8 days), adjusting for key covariates. The duration of weaning is also prolonged among infants with greater NOWS symptom severity and with prenatal exposure to psychotropic medications. CONCLUSIONS: Delayed treatment prolongs NOWS symptoms and increases the burden on the health care system. Earlier referral from NICUs to pediatric inpatient units with environmental supports could reduce prolonged medication exposure and length of hospitalization for infants diagnosed with NOWS.

THE EFFECT OF LOW TO MODERATE PRENATAL ALCOHOL EXPOSURE AND BINGE DRINKING EPISODES ON DRAW-A-PERSON AT AGE 5 YEARS.

This study examined the effects of maternal alcohol consumption and binge drinking during pregnancy on children's Draw-A-Person (DAP) scores. Participants were 1,533 5-year-olds from the Danish National Birth Cohort. Regression analyses revealed an adverse effect of nine or more drinks per week. A drop in mean DAP score of 6.26 (95 % CI: -12.24; -0.39) was observed in the fully adjusted model. A significant interaction between average weekly consumption and binge episodes also was observed. Findings suggest that prenatal exposure to moderate weekly doses of alcohol and binge drinking episodes are associated with lowered scores on the DAP.

Assessing the association between natural food folate intake and blood folate concentrations: a systematic review and Bayesian meta-analysis of trials and observational studies.

Folate is found naturally in foods or as synthetic folic acid in dietary supplements and fortified foods. Adequate periconceptional folic acid intake can prevent neural tube defects. Folate intake impacts blood folate concentration; however, the dose-response between natural food folate and blood folate concentrations has not been well described. We estimated this association among healthy females. A systematic literature review identified studies (1 1992-3 2014) with both natural food folate intake alone and blood folate concentration among females aged 12-49 years. Bayesian methods were used to estimate regression model parameters describing the association between natural food folate intake and subsequent blood folate concentration. Seven controlled trials and 29 observational studies met the inclusion criteria. For the six studies using microbiologic assay (MA) included in the meta-analysis, we estimate that a 6% (95% Credible Interval (CrI): 4%, 9%) increase in red blood cell (RBC) folate concentration and a 7% (95% CrI: 1%, 12%) increase in serum/plasma folate concentration can occur for every 10% increase in natural food folate intake. Using modeled results, we estimate that a natural food folate intake of ≥ 450 µg dietary folate equivalents (DFE)/day could achieve the lower bound of an RBC folate concentration (~ 1050 nmol/L) associated with the lowest risk of a neural tube defect. Natural food folate intake affects blood folate concentration and adequate intakes could help women achieve a RBC folate concentration associated with a risk of 6 neural tube defects/10,000 live births.

Assessing the association between the methylenetetrahydrofolate reductase (MTHFR) 677C>T polymorphism and blood folate concentrations: a systematic review and meta-analysis of trials and observational studies.

BACKGROUND: The methylenetetrahydrofolate reductase (MTHFR) 677C>T polymorphism is a risk factor for neural tube defects. The T allele produces an enzyme with reduced folate-processing capacity, which has been associated with lower blood folate concentrations. OBJECTIVE: We assessed the association between MTHFR C677T genotypes and blood folate concentrations among healthy women aged 12-49 y. DESIGN: We conducted a systematic review of the literature published from January 1992 to March 2014 to identify trials and observational studies that reported serum, plasma, or red blood cell (RBC) folate concentrations and MTHFR C677T genotype. We conducted a meta-analysis for estimates of percentage differences in blood folate concentrations between genotypes. RESULTS: Forty studies met the inclusion criteria. Of the 6 studies that used the microbiologic assay (MA) to measure serum or plasma (S/P) and RBC folate concentrations, the percentage difference between genotypes showed a clear pattern of CC > CT > TT. The percentage difference was greatest for CC > TT [S/P: 13%; 95% credible interval (CrI): 7%, 18%; RBC: 16%; 95% CrI: 12%, 20%] followed by CC > CT (S/P: 7%; 95% CrI: 1%, 12%; RBC: 8%; 95% CrI: 4%, 12%) and CT > TT (S/P: 6%; 95% CrI: 1%, 11%; RBC: 9%; 95% CrI: 5%, 13%). S/P folate concentrations measured by using protein-binding assays (PBAs) also showed this pattern but to a greater extent (e.g., CC > TT: 20%; 95% CrI: 17%, 22%). In contrast, RBC folate concentrations measured by using PBAs did not show the same pattern and are presented in the Supplemental Material only. CONCLUSIONS: Meta-analysis results (limited to the MA, the recommended population assessment method) indicated a consistent percentage difference in S/P and RBC folate concentrations across MTHFR C677T genotypes. Lower blood folate concentrations associated with this polymorphism could have implications for a population-level risk of neural tube defects.
