RESUMO

Pregnancy is a unique time when amplified sex steroid concentrations promote an escalation in vitamin D binding protein (DBP) synthesis, associated with increased total vitamin D and metabolites, including 25-hydroxyvitamin D (25(OH)D). Free 25(OH)D concentration increases disproportionately to total 25(OH)D during pregnancy, likely an adaptation to supply the woman and fetus with readily available 25(OH)D. Highlighting the importance of the calcium metabolic stress during pregnancy, the interactional relationship between serum 25(OH)D and PTH has been evaluated. Maternal total 25(OH)D and total 25(OH)D/iPTH are measures of vitamin D status and biomarkers for potential pregnancy complications. It has been proposed that free 25(OH)D and free 25(OH)D/iPTH could be better indicators of vitamin D status and predictors of pregnancy complications such as gestational diabetes (GDM), hypertensive disorders of pregnancy, and preterm delivery. This study aims to determine if free 25(OH)D and its association with PTH are more accurate predictors of comorbidities of pregnancy than total 25(OH)D and its association with PTH. In this post hoc analysis of the Kellogg Pregnancy Study, a double-blind randomized placebo-controlled trial, participants included 297 women with singleton pregnancies: 191 participants were randomized into a group receiving a daily prenatal (400 IU vitamin D3) while 196 received a prenatal plus extra supplementation (4400 IU vitamin D3). Blood and urine samples were collected monthly. 297 participants' serum total 25(OH)D concentrations were measured using radioimmunoassay at baseline (visit 1) and 5-7 months' gestation (visit 6-7). 93 participants' serum free 25(OH)D and PTH concentrations were measured using ELISA and immunoradiometric assay, respectively, at visit 1 and 6-7; 66 participants had paired samples and were included in this analysis. Data were analyzed using SAS 9.4, Cary, N.C. or SPSS v28, IBM Corporation, Armonk, N.Y. Results were considered significant with a p < 0.05. A significant relationship exists between the ratio of total 25(OH)D/iPTH and free 25(OH)D/iPTH grouped by total 25(OH)D ≥ 30 ng/mL and < 30 ng/mL as an indicator of maternal vitamin D status. There was a statistically significant relationship between lower mean free 25(OH)D/iPTH and the development of GDM at visit 1 (p = 0.0003) and at visit 6-7 (p = 0.001) while total 25(OH)D/iPTH and GDM were significantly related only at visit 1 (p = 0.029). In this exploratory cohort, neither free 25(OH)D/iPTH nor total 25(OH)D/iPTH were significantly associated with increased incidence of preterm delivery, hypertensive disorders, or combined comorbidities of pregnancy. An univariate logistic regression evaluating the outcome of gestational diabetes while independently controlling for independent factors showed the ratio of free 25(OH)D/iPTH was more closely associated with gestational diabetes than the ratio of total 25(OH)D/iPTH, although neither were significant. This proof-of-concept analysis suggests that the ratio of free 25(OH)D/iPTH is associated with the development of gestational diabetes throughout pregnancy while total 25(OH)D/iPTH is only associated with the outcome early in pregnancy. Further investigation is warranted to explore this relationship between calcium metabolic stress during pregnancy with a larger cohort to improve validity,reproducibility, and relevance to other pregnancy comorbidities.

RESUMO

INTRODUCTION: Vitamin D (VitD) has been shown to impact neurodevelopment. Studies have shown that higher 25-hydroxy-vitamin D (25(OH)D) concentrations (the indicator of vitD status) may be associated with better neurodevelopmental outcomes, although current data are conflicting. This study examined the relationship between total circulating 25(OH)D concentrations and neurodevelopmental outcomes in 3-5-year-old (3-5 yo) children. METHODS: In this study, pregnant women were randomized to receive 400 (standard dose), 2000, or 4000 IU vitD3/day. Offspring then underwent the Brigance Screen at 3-5 yo. The 25(OH)D concentration was measured at birth and 3-5 yo. Relationships between Brigance scores and 25(OH)D and Brigance scores and vitamin D binding protein (VDBP) genotype were examined. RESULTS: Higher 25(OH)D at the time of testing was associated with better overall performance on neurodevelopmental testing as measured by the Brigance quotient (B = 0.208, p = 0.049). Scores were then broken down into sub-scores. Children born to mothers in the 2000 IU/day group scored higher on the Brigance language component of the assessment versus the standard dose group (B = 4.667, p = 0.044). The group of children who had the Gc1f-1s or Gc1f-2 genotypes scored higher on the Brigance academic component (B = 9.993, p < 0.001) and lower on the Brigance language component versus the 1f1f genotype (B = -9.313, p < 0.001). Children with the Gc1s-1s, Gc1s-2, or Gc2-2 genotypes also scored lower than the Gc1f-1f genotype (B = -6.757, p = 0.003). CONCLUSION: These results suggest that higher 25(OH)D concentrations early in life and higher doses of maternal vitamin D supplementation during pregnancy may have a positive association with neurodevelopmental outcomes. This study also suggests that the VDBP genotype is associated with neurodevelopment and differentially affects various fields of neurodevelopment.

RESUMO

OBJECTIVE: This article aims to determine the association between maternal 25-hydroxy-vitamin D [25(OH)D] status and intake of hormonal oral contraceptive pills (OCPs) in women who are lactating. STUDY DESIGN: Women who were exclusively breastfeeding participated in a randomized controlled trial assessing vitamin D supplementation at 400, 2,400, or 6,400 international unit (IU)/d from 1 month through 7 months postpartum. This observational, secondary analysis assessed whether OCPs were associated with maternal 25(OH)D concentrations in women who are lactating. Multivariate regression models were used to predict 25(OH)D concentrations and create parameter estimates for each variable. RESULTS: In a bivariate analysis, the use of OCPs at 4 months was associated with increased serum 25(OH)D (p = 0.02). OCPs' use at 7 months was associated with a higher trend in 25(OH)D, but this finding was not statistically significant (p = 0.1). In a multivariate regression model at 4 months, independent positive predictors of 25(OH)D concentrations were the use of OCPs (p = 0.03) and treatment with vitamin D at 6,400 IU/d (p ≤ 0.0001). Negative predictors were Black (p = 0.001) and Hispanic (p = 0.0001) race and ethnicity, and body mass index (BMI) greater than 30 (p = 0.0002). The same pattern occurred at 7 months, with more southern latitude as a positive independent predictor (p = 0.04) of 25(OH)D concentration. CONCLUSION: The use of OCPs was associated with greater 25(OH)D in women who are lactating. Additionally, treatment with vitamin D at 6,400 IU/d and southern latitude was associated with greater 25(OH)D in women who are lactating. Black and Hispanic race and ethnicity, and BMI greater than 30, were independently associated with lower 25(OH)D in women who are lactating. KEY POINTS: · The association of OCP with serum 25(OH)D concentrations during postpartum lactation is unknown.. · OCPs' use was associated with higher 25(OH)D concentrations in postpartum women who are lactating.. · Treatment with vitamin D and southern latitude was associated with greater 25(OH)D in women who are lactating.. · Black and Hispanic, and BMI > 30 were associated with lower 25(OH)D in women who are lactating.. · Practitioners can counsel women who are lactating on OCPs' use and the positive effects on their 25(OH)D status..

RESUMO

INTRODUCTION: Positive effects of vitamin D (vitD) supplementation on comorbidities of pregnancy (COP) have been explored; however, few studies have elucidated the pathophysiology behind the development of these COP and the potential relationship with derangements in placental development and morphology. Additionally, it is known that placentas weighing 10th-90th % for gestational age are associated with better outcomes. Therefore, the objective of this study was to assess the impact of resulting circulating serum 25(OH)D concentrations associated with intake of high or low doses of supplementary vitD on placental development and morphology in women who participated in a randomized double blind, placebo-controlled trial of vitD supplementation. We hypothesized that if maternal serum 25(OH)D concentration (vitD status marker) is insufficient/deficient, then placental weight and % for gestational age (GA) will be smaller and will correlate with increased vascular and inflammatory placental pathologic findings. METHODS: The findings of the present study are a secondary analysis of data generated from a previously reported randomized controlled trial (RCT), the Kellogg Vitamin D Pregnancy Study. Pregnant women (n = 297) in this RCT (January 2013 - April 2018) were randomly assigned to 400 IU vs. 4400 IU vitD/day (10-14 weeks' gestational age) and followed to delivery. 132 placentas were analyzed by pathologists blinded to treatment, and the 2016 Amsterdam Consensus Criteria were used to categorize grouping/grading of placental pathology and weight. Total [25(OH)D] was measured using radioimmunoassay (ng/mL). Chi-square and Student's t-test were used to show the difference in maternal characteristics by treatment group and by placental weight. Chi-square analysis was used to determine differences between the percent pathology findings by treatment group. Students t-test was used to determine the differences in vitD status and the frequency of placental lesions. Association between [25(OH)D] area under the curve (AUC) and placental morphology were determined in a regression model that included maternal BMI ≥ 30 kg/m2, race/ethnicity, and vitD treatment group allocation. Data were analyzed using SAS v9.4 (Cary, NC) and statistical significance was indicated by p < 0.05. RESULTS: The percent pathology findings by treatment group were not significantly different for each of the placental pathology categories as defined by the 2016 Amsterdam Consensus Criteria including placental weight. However, when using 25(OH)D as a biomarker for vitD status, linear regression model showed maternal serum [25(OH)D] AUC was significantly associated with greater placental weight (p = 0.023). Logistic regression models showed mothers with BMI ≥ 30 kg/m2 had larger placental weight (p = 0.046), and Hispanic and white/Caucasian mothers had greater placental weights than Black American mothers (p = 0.025). When placentas ≥ 90th % for GA, n = 7, were removed from the placental pool, Pearson correlation still showed a positive association between maternal serum 25(OH)D AUC and placental weight (p = 0.011). In a second linear regression model of placentas ≥ 90th % for GA (n = 7) vs. placentas < 90th % (n = 108), maternal serum 25(OH)D AUC was significantly greater in those placentas ≥ 90th % (p = 0.03); however, this was not associated with increased perinatal mortality. CONCLUSION FINDINGS: suggest increasing maternal serum [25(OH)D] via vitamin D supplementation during pregnancy did not adversely affect placental morphology; trends showed those in the treatment group had fewer placental lesions. Placental weight was found to be significantly associated with [25(OH)D] AUC, which represents maternal vitamin D status over the course of pregnancy; 7 placentas ≥ 90th % for GA were not associated with perinatal mortality.

RESUMO

Understanding patterns of opioid receipt by children and adolescents over time and understanding differences between age groups can help identify opportunities for future opioid stewardship. We conducted a retrospective cohort study, using South Carolina Medicaid data for children and adolescents 0-18 years old between 2000-2020, calculating the annual prevalence of opioid receipt for medical diagnoses in ambulatory settings. We examined differences in prevalence by calendar year, race/ethnicity, and by age group. The annual prevalence of opioid receipt for medical diagnoses changed significantly over the years studied, from 187.5 per 1000 in 2000 to 41.9 per 1000 in 2020 (Cochran-Armitage test for trend, p < 0.0001). In all calendar years, older ages were associated with greater prevalence of opioid receipt. Adjusted analyses (logistic regression) assessed calendar year differences in opioid receipt, controlling for age group, sex, and race/ethnicity. In the adjusted analyses, calendar year was inversely associated with opioid receipt (aOR 0.927, 95% CI 0.926-0.927). Males and older ages were more likely to receive opioids, while persons of Black race and Hispanic ethnicity had lower odds of receiving opioids. While opioid receipt declined among all age groups during 2000-2020, adolescents 12-18 had persistently higher annual prevalence of opioid receipt when compared to younger age groups.

RESUMO

OBJECTIVE: Our objective was to conduct a secondary, post hoc analysis of the National Institute of Child Health and Human Development (NICHD) vitamin D (vitD) pregnancy study by Hollis et al, which reported on the effect of vitD supplementation in pregnant women and determine the potential interaction between intact parathyroid hormone (iPTH) concentrations, vitD status, and various comorbidities associated with pregnancy. Women with low 25-hydroxy vitamin D (25(OH)D) concentrations and high iPTH concentrations during pregnancy, known as functional vitamin-D deficiency (FVDD), were more likely to acquire complications also affecting their neonates. STUDY DESIGN: This post hoc analysis of data collected from a diverse group of pregnant women participating in the NICHD vitD pregnancy study was applied to investigate the applicability of the concept of FVDD in pregnancy (Hemmingway, 2018) in identifying potential risks for certain comorbidities of pregnancy. This analysis defines FVDD as maternal serum 25(OH)D concentrations below 20 ng/mL and iPTH concentrations above 65 pg/mL creating a definitive ratio number, 0.308, to classify mothers as having FVDD prior to delivery (PTD). Statistical analyses were performed using SAS 9.4 (Cary, NC). RESULTS: In total, 281 women (85 African American, 115 Hispanic, and 81 Caucasian) with 25(OH)D and iPTH concentrations measured at monthly visits were included in this analysis. No statistically significant association was found between mothers classified as having FVDD at baseline or 1-month PTD and hypertensive disorders of pregnancy, infection, or admittance to the neonatal intensive care unit. When combining all comorbidities of pregnancy in this cohort, results showed those with FVDD at baseline, 24 weeks' gestation, and 1-month PTD were more likely to experience a comorbidity (p = 0.001; p = 0.001; p = 0.004, respectively). Those with FVDD 1-month PTD were 7.1 times (confidence interval [CI]: 1.71-29.81) more likely to have preterm birth (<37 weeks) than women without FVDD. CONCLUSION: Participants were more likely to have experienced preterm birth if they met the criteria for FVDD. This study supports the importance of FVDD during pregnancy. KEY POINTS: · Functional vitamin D deficiency (FVDD) is defined as the ratio of 25(OH)D divided by iPTH concentration ≤0.308.. · At a minimum, it is recommended that vitamin D status be kept in the healthy range based on current recommendations for pregnant individuals.. · FVDD is a more sensitive predictor of pregnancy risk than 25(OH)D alone.. · FVDD identified those with greater risk of preterm birth in this cohort..

RESUMO

To examine the growth and body composition of small for gestational age (SGA) and appropriate for gestational age (AGA) very low birth weight infants (VLBW) and their outpatient neurodevelopmental outcomes. From 2006-2012, VLBW infants (n = 57 of 92) admitted to the Neonatal Intensive Care Unit (NICU) had serial air displacement plethysmography (ADP) scans and were followed as outpatients. Serial developmental testing (CAT/CLAMS, Peabody Gross Motor Scales) and anthropometrics were obtained from n = 37 infants (29 AGA and 8 SGA) and analyzed via repeated measures analyses of variances. The percentage of body fat, percentage of lean mass, and weight gain were statistically significant between SGA and AGA groups at the first ADP assessment. There was no difference between the two groups in outpatient neurodevelopmental testing. Weight gain as "catch-up" body fat accrual occurs by 67 weeks of PMA. This catch-up growth is associated with normal SGA preterm neurodevelopment as compared to AGA preterm infants.

RESUMO

Background: Vitamin D (vitD) plays a major role in maintenance of bone mineral homeostasis. It is unknown if bone mineral content (BMC) and bone mineral density (BMD) differ between infants who receive direct vitD supplementation and those who receive vitD indirectly via their mother's breast milk, while she received a high dose of vitD. It is hypothesized that there would be no differences in BMC or BMD by treatment group. Design/Methods: Randomized, double-blind trial to compare BMD and BMC of infants who received direct vitD (400 IU vitD3/day) in addition to their mother receiving standard dosage (400 IU vitD3/day) versus infants whose mothers were their only source of vitD and were given high-dose supplementation (6,400 IU vitD3/day). Participants were exclusively breastfeeding mothers and their infant consuming only human milk. Infant BMC and BMD were measured by dual-energy X-ray absorptiometry (DXA) scans of the infant's total body using Hologic Discovery A Densitometer and analyzed using Hologic Infant software at 1, 4, and 7 months of age. Results: Infant BMC and BMD did not differ significantly at 1, 4, or 7 months of age between direct and indirect supplementation arms. The mean difference in BMC from 1 to 7 months was 1.624 and 1.464 g for the 400 and 6,400 IU groups, respectively, (p = 0.5); the mean difference in BMD over this same period was 0.042 and 0.032 g/cm2 for the 400 and 6,400 IU groups, respectively (p = 0.2). Although some differences among races were observed, this did not reflect changes in bone growth between the treatment arms. Conclusion: High-dose vitD supplementation of mothers during lactation provided an efficacious alternative to direct supplementation of infants, as evidenced by noninferior infant BMD and BMC. Clinical Trial Registration number: NCT00412074.

RESUMO

Background: To ensure the safety of higher dose vitamin D supplementation in pregnant and lactating mothers, and urinary calcium/creatinine (UCa/Cr) ratios, serum calcium, and serum 25(OH)D concentrations are closely monitored. To achieve optimal maternal and infant vitamin D status, while avoiding hypercalcemia, safety measures assessing vitD supplementation must be reliable. Whether or not this holds true for infants before 7 months of age, remains unknown. Objective: Analyze the association among UCa/Cr ratio, serum calcium, intact serum parathyroid hormone (iPTH), 25(OH)D, and 25(OH)D/iPTH ratio in infants to determine whether evidence supports the use of these parameters as valuable measures of hypervitaminosis D or toxicity in infants. Methods: A series of analyses were performed on the cohort of infants who participated in the National Institute of Child Health and Human Development lactation vitD supplementation trial to determine the association among UCa/Cr ratio, serum calcium, iPTH, 25(OH)D, and 25(OH)D/iPTH ratio. Results: Upon multivariate analysis, serum calcium was significantly associated with 25(OH)D (p = 0.0441), iPTH (p = 0.0017), and 25(OH)D/iPTH ratio (p = 0.0001). Infant UCa/Cr did not associate with 25(OH)D but did associate with iPTH (p = 0.0008) and 25(OH)D/iPTH ratio (p = 0.0001). The correlation between UCa/Cr and 25(OH)D/iPTH ratios was significantly stronger than the association between UCa/Cr ratio and iPTH. Serum calcium more strongly correlated with 25(OH)D/iPTH ratio versus 25(OH)D and iPTH. Conclusion: In this healthy cohort of infants 1 to 7 months old, UCa/Cr and serum calcium are more valid indicators of 25(OH)D/iPTH ratio than either 25(OH)D or iPTH alone. Moreover, serum calcium (and not UCa/Cr) is a valid indicator of infant total circulating 25(OH)D and should be measured if vitamin D toxicity is a concern.

RESUMO

OBJECTIVES: Determine which sociodemographic factors are most associated with increased maternal perceived stress during pregnancy. Evaluate the association between maternal stress and plasma immune-mediator concentrations (IMCs). METHODS: As part of a prospective, randomized clinical trial, 247 participants completed a Perceived Stress Scale survey (PSS-10) during each trimester of pregnancy. Blood samples were collected from participants and were analyzed for 25-hydroxyvitamin D (25(OH)D) concentration and for several IMCs: interferon-gamma, interleukins (IL-) IL-2, IL-4, IL-5, IL-10, vascular endothelial growth factor, c-reactive protein, and tumor necrosis factor alpha (TNF-α) (R&D Elisa). The potential associations between PSS-10 scores, sociodemographic factors, and IMCs were assessed. RESULTS: In bivariate analysis, participants who were not married and/or had high risk pregnancies were more likely to have increased PSS-10 scores (p<0.05). Increased PSS-10 scores were associated with higher serum concentrations of IL-2 and TNF-α, and decreased concentrations of IL-10 and 25(OH)D. In linear regression analysis, single marital status, high-risk pregnancy, IL-2, and TNF-α were independent predictors of PSS-10 scores. CONCLUSIONS: This study identifies specific sociodemographic factors that are associated with increased perceived stress during pregnancy. This study also provides evidence that increased perceived stress is associated with physiological changes as measured by changes in circulating IL-2, TNF-α, IL-10, and 25(OH)D concentrations.

RESUMO

Background: Racial disparities in breastfeeding rates persist in the United States with Black women having the lowest rates of initiation and continuation. A literature review attributes this to many factors-historical roles, cultural norms, lack of social support, and systemic racism in the health care and lactation support system. The Baby-Friendly Hospital Initiative (BFHI) is an evidence-based program to increase breastfeeding through standardized protocols, and, in a Southeastern U.S. academic center, it was associated with increased breastfeeding, but the effect on racial disparities in breastfeeding was unknown. Methods: Through an institutional Perinatal Information Systems database, breastfeeding rates were compared before and after BFHI implementation. Breastfeeding initiation, sustained breastfeeding 24-hours before discharge, and patient demographics were assessed. Results: After BFHI implementation, mothers were overall 1.17 (95% confidence interval: 1.13-1.19) times more likely to initiate breastfeeding. For Black mothers, breastfeeding initiation increased significantly from 52% to 66%, but they were significantly less likely to sustain in-hospital breastfeeding compared to nonBlack mothers (69.4% versus 84.6%, p < 0.0001). Several demographic and medical comorbidities were significantly associated with failure to sustain breastfeeding to hospital discharge. When controlling for these factors, the racial disparity persisted. Conclusions: Since BFHI implementation, the racial gap in breastfeeding initiation decreased, but a significant disparity remained for sustained in-hospital breastfeeding. This study highlights the success of the BFHI program, but in the context of the current literature, also reveals the need for further work to ensure interventions are culturally competent and delivered equitably to support sustained breastfeeding for Black women.

RESUMO

Background: The safety of higher dose vitamin D (vitD) supplementation in women who change from exclusive or full breastfeeding to combination feeding or who continue supplementation after cessation of breastfeeding is unknown. Objective: Compare vitD supplementation safety of 6,400 to 400 IU/day and 2,400 IU/day using specific laboratory parameters in postpartum women and their infants through 7 months postpartum by feeding type. Design: In this randomized controlled trial, mothers (exclusively breastfeeding or formula-feeding) were randomized at 4-6 weeks' postpartum to 400, 2,400, or 6,400 IU vitD3 (cholecalciferol)/day for 6 months. Breastfeeding infants in 400 IU group received oral 400 IU vitD3/day; infants in 2,400 and 6,400 IU groups received placebo. Maternal safety parameters (serum vitD, 25-hydroxy-vitamin D [25(OH)D; calcidiol], calcium, phosphorus, intact PTH; urinary calcium/creatinine ratios; and feeding type/changes) were measured monthly; infant parameters were measured at months 1, 4, and 7. Sufficiency was defined as 25(OH)D >50 nmol/L. Feeding type was defined as exclusive/full, combination, or formula-feeding. Data were analyzed using SAS 9.4. Results: Four hundred nineteen mother-infant pairs were randomized into the three treatment groups and followed: 346 breastfeeding and 73 formula-feeding pairs. A dose of 6400 IU/day safely and significantly increased maternal vitD and 25(OH)D from baseline in all mothers regardless of feeding type (p < 0.0001) and was superior to the 400 and 2,400 IU groups in achieving vitD sufficiency with no other differences in safety parameters by treatment or feeding type. Infants in the 2,400 IU group were more likely vitD-deficient than the other groups; otherwise, there were no infant safety parameter differences. Conclusions: While 6,400 IU/day was more effective than 400 or 2,400 IU/day in achieving maternal vitD sufficiency in all feeding groups, the groups did not differ on other safety parameters. Similarly, infant safety parameters did not differ by treatment group or feeding status. Clinical Trial Registration: FDA IND Number: 66,346; ClinicalTrials.gov Number: NCT00412074.

RESUMO

OBJECTIVES: To compare the frequency of opioid and corticosteroid prescriptions dispensed for children with pneumonia or sinusitis visits on the basis of location of care. METHODS: We evaluated 2016 South Carolina Medicaid claims data for 5 to 18 years olds with pneumonia or sinusitis. Visits were associated with 1 of 3 locations: the emergency department (ED), urgent care, or the ambulatory setting. RESULTS: Inclusion criteria were met by 31 838 children. Pneumonia visits were more often linked to an opioid prescription in the ED (34 of 542 [6.3%]) than in ambulatory settings (24 of 1590 [1.5%]; P ≤ .0001) and were more frequently linked to a steroid prescription in the ED (106 of 542 [19.6%]) than in ambulatory settings (196 of 1590 [12.3%]; P ≤ .0001). Sinusitis visits were more often linked to an opioid prescription in the ED (202 of 2705 [7.5%]) than in ambulatory settings (568 of 26 866 [2.1%]; P ≤ .0001) and were more frequently linked to a steroid prescription in the ED (510 of 2705 [18.9%]) than in ambulatory settings (1922 of 26 866 [7.2%]; P ≤ .0001). In logistic regression for children with pneumonia, the ED setting was associated with increased odds of receiving an opioid (adjusted odds ratio [aOR] 4.69) or steroid (aOR 1.67). Similarly, patients with sinusitis were more likely to be prescribed opioids (aOR 4.02) or steroids (aOR 3.05) in the ED than in ambulatory sites. CONCLUSIONS: School-aged children received opioid and steroid prescriptions for pneumonia or sinusitis at a higher frequency in the ED versus the ambulatory setting.

RESUMO

Objective. This study tested the sensitivity of obesity diagnosis in electronic health records (EHRs) using body mass index (BMI) classification and identified variables associated with obesity diagnosis. Methods. Eligible children aged 2 to 18 years had a calculable BMI in 2017 and had at least 1 visit in 2016 and 2017. Sensitivity of clinical obesity diagnosis compared with children's BMI percentile was calculated. Logistic regression was performed to determine variables associated with obesity diagnosis. Results. Analyses included 31 059 children with BMI at or above 95th percentile. Sensitivity of clinical obesity diagnosis was 35.81%. Clinical obesity diagnosis was more likely if the child had a well visit, had Medicaid insurance, was female, Hispanic or Black, had a chronic disease diagnosis, and saw a provider in a practice in an urban area or with academic affiliation. Conclusion. Sensitivity of clinical obesity diagnosis in EHR is low. Clinical obesity diagnosis is associated with nonmodifiable child-specific factors but also modifiable practice-specific factors.

RESUMO

The objective of this investigation was to compare bioavailability between single oral dose Vitamin D3 (vitD3) gummies vs. tablets in healthy adults. An initial crossover, randomized clinical trial involving healthy adults (n = 9) was conducted followed by a larger, confirmatory study (n = 31). Healthy participants aged 18-45 years with body mass index (BMI) 18-30 without anemia or vitD deficiency were randomized to receive 20,000 international units (IU) vitD3 as single dose gummies or tablets with serial samples obtained to measure plasma vitD3 at baseline, 3, 6, 10, 24, and 48 h followed by a 2-week washout period. The same participants then crossed over to receive 20,000 IU vitD3 in the form not previously given, with sampling at the same time points. Deidentified blood samples were analyzed for vitD3 concentration by liquid chromatography (LC)-mass spectroscopy. In Study 1, results suggested bioavailability was greater with gummies compared with tablets, (effect size 1.08 at 24 h). In Study 2, the area under the concentration curve (AUC) was higher with gummies than tablets (gummy mean (95% CI): 1474 ng·/mL (1393-1555); tablet mean (95% CI): 774 ng·h/mL (693-855), p < 0.0001). Average peak blood concentration (Cmax) values were significantly higher with gummies (gummy: 47.3 ng/mL; tablet: 23.4 ng/mL; p < 0.0001). VitD3 gummies had greater bioavailability than tablets with higher vitD concentrations over time, which may have implications for achieving vitD sufficiency.

RESUMO

BACKGROUND: The effect electronic health record (EHR) implementation has on physician satisfaction and patient care remains unclear. A better understanding of physician perceptions of EHRs and factors that influence those perceptions is needed to improve the physician and patient experience when using EHRs. OBJECTIVE: The objective of this study was to determine provider and clinical practice factors associated with physician EHR satisfaction and perception of patient impact. METHODS: We surveyed a random sample of physicians, including residents and fellows, at a US quaternary care academic hospital from February to March 2016. The survey assessed provider demographics, clinical practice factors (ie, attending, fellow, or resident), and overall EHR experience. The primary outcomes assessed were provider satisfaction and provider perceptions of impact to patient care. Responses on the satisfaction and patient impact questions were recorded on a continuous scale initially anchored at neutral (scale range 0 to 100: 0 defined as "extremely negatively" and 100 as "extremely positively"). Independent variables assessed included demographic and clinical practice factors, including perceived efficiency in using the EHR. One-way analysis of variance or the Kruskal-Wallis test was used for bivariate comparisons, and linear regression was used for multivariable modeling. RESULTS: Of 157 physicians, 111 (70.7%) completed the survey; 51.4% (57/111) of the respondents were attending physicians, and of those, 71.9% (41/57) reported a >50% clinical full-time-equivalency and half reported supervising residents >50% of the time. A total of 50.5% (56/111) of the respondents were primary care practitioners, previous EHR experience was evenly distributed, and 12.6% (14/111) of the total sample were EHR super-users. Responses to how our current EHR affects satisfaction were rated above the neutral survey anchor point (mean 58 [SD 22]), as were their perceptions as to how the EHR impacts the patient (mean 61 [SD 18]). In bivariate comparisons, only physician age, clinical role (resident, fellow, or attending), and perceived efficiency were associated with EHR satisfaction. In the linear regression models, physicians with higher reported perceived efficiency reported higher overall satisfaction and patient impact after controlling for other variables in the model. CONCLUSIONS: Physician satisfaction with EHRs and their perception of its impact on clinical care were generally positive, but physician characteristics, greater age, and attending level were associated with worse EHR satisfaction. Perceived efficiency is the factor most associated with physician satisfaction with EHRs when controlling for other factors. Understanding physician perceptions of EHRs may allow targeting of technology resources to ensure efficiency and satisfaction with EHR system use during clinical care.

RESUMO

The purpose of the current study was to investigate desired weight percentage and weight difference percentage and their association with treatment outcome in a novel family-based partial hospitalization program. Twenty-six adolescents with anorexia nervosa or subthreshold anorexia nervosa between the ages of 12 and 19 completed the Eating Disorder Examination (EDE) at intake and upon completion from a partial hospitalization program in which parents played a large role in the recovery process, consistent with family-based treatment principles. Lower desired weight percentage at baseline was associated with higher scores on the restraint subscale of the EDE at end of treatment. Higher weight difference percentage (greater desire to lose weight) at baseline was associated with higher scores on all EDE subscales and global score at end of treatment. Neither desired weight percentage nor weight difference percentage at baseline were associated with treatment dropout or percent expected body weight at end of treatment. In a family-based program, participants' desired weight may be related to eating disorder thoughts (for example, shape or weight concerns) but not to behavioral outcomes such as weight gain or treatment dropout, which may be more directly under the influence of the parents.

RESUMO

OBJECTIVE: To identify the vitamin D status to optimize calcium and bone health in preterm infants. STUDY DESIGN: Very low birth weight infants had measurement of 25-hydroxyvitamin D status and markers of calcium and bone health from birth to term age. Piecewise linear regression modeling was performed to identify a 25-hydroxyvitamin D threshold associated with stable parathyroid hormone concentration and bone mineralization. RESULTS: In a cohort of 89 infants at term age, femur BMC and density increased linearly with 25-hydroxyvitamin D status until reaching a threshold of 48 ng/mL and 46 ng/mL, respectively. Parathyroid hormone status decreased as vitamin D status increased until reaching a plateau at 25-hydroxyvitamin D of 42 ng/mL. CONCLUSION: Preterm infant vitamin D status was significantly associated with PTH status and femur mineralization with suggestion that achieving a specific 25-hydroxyvitamin concentration is associated with optimal calcium homeostasis and femur bone mineralization.

RESUMO

BACKGROUND AND OBJECTIVES: Asthma is a common reason for hospital readmission. The majority of children are not receiving adequate preventive care after discharge. Our objective is to decrease return visits to the emergency department (ED) or hospital for asthma through a series of interventions (eg, access to real-time claims data and structured follow-up phone calls) designed to increase preventive care. METHODS: We performed a single-site quality improvement project for children 2 to 17 years old discharged with asthma from January 2010 to March 2014. We compared a baseline period and a stepwise intervention period including the following: brief follow-up phone calls to families, access to medication claims data, and structured phone calls. The primary outcome of return visits to the ED or hospital and preventive care outcomes (controller refills and ambulatory visits) up to 90 days were assessed using state all-payer and Medicaid data sets. Interrupted time series analysis was used to investigate secular trends. RESULTS: Six hundred and seventy-seven asthma discharges were analyzed. The majority of children were 2 to 7 years old, African American, and insured by Medicaid. Successful phone contact occurred in 57% of encounters. Ninety-day revisits to the ED or hospital demonstrated a significant decline (15% to 8%; P < .05), but preventive care measures did not improve. CONCLUSIONS: A process to improve transitions for children who are hospitalized with an asthma exacerbation that includes follow-up phone calls was associated with a decrease in ED or hospital revisits. The lack of a detectable increase in preventive care warrants further exploration.

RESUMO

Objective To propose and assess a composite endpoint (CE) of neonatal benefit based on neonatal mortality and morbidities by gestational age (GA) for use in preterm labor clinical trials. Study Design A descriptive, retrospective analysis of the Medical University of South Carolina Perinatal Information System database was conducted. Neonatal morbidities were assessed for inclusion in the CE based on clinical significance/risk of childhood neurodevelopmental impairment, frequency, and association with GA in a mother-neonate linked cohort, comprising women with uncomplicated singleton pregnancies delivered at ≥24 weeks' GA. Results Among 17,912 mother-neonate pairs, neonates were at a risk of numerous severe but infrequent morbidities. Clinically important, predominantly rare events were combined into a CE comprising neonatal mortality and morbidities, which decreased in frequency with increasing GA. The highest CE frequency occurred at <31 weeks. High frequency of respiratory distress syndrome, bronchopulmonary dysplasia, and sepsis drove the CE. Median length of hospital stay was longer at all GAs in those with the CE compared with those without. Conclusions Descriptive epidemiological assessment and clinical input were used to develop a CE to measure neonatal benefit, comprising clinically meaningful outcomes. These empirical data and CE allowed trials investigating tocolytics to be sized appropriately.
