RESUMO

OBJECTIVE: The study aimed to assess in a prospective randomized study the effect of Mozart's music on time to regain birth weight (BW) and development of oral feeding skills in babies born between 280/7 and 316/7 weeks of gestation. STUDY DESIGN: Healthy premature infants born between 280/7 and 316/7 completed weeks of gestation were randomized within 3 days of birth to either music or no music exposure. Infants in the music group were exposed to Mozart's double piano sonata twice per day for 14 days. The primary outcome was time to regain birth weight. The secondary outcome was development of oral feeding skills as evaluated by a speech/language pathologist blinded to the intervention. We hypothesized that exposure to Mozart's double piano sonata would decrease time to regain BW and improve feeding skills. A total of 32 newborns were needed to detect a 3-day difference in time to regain BW. RESULTS: Forty infants were enrolled and randomized. There were no significant differences between the two groups regarding the time to regain BW (p = 0.181) and the time to achievement of full oral feeds (p = 0.809). CONCLUSION: Exposure to Mozart's double piano sonata for 14 days after birth did not significantly improve time to regain BW or time to achieve full oral feedings in very premature infants. It is possible that Mozart's music has no effect or that the duration of music exposure was not sufficient to have a physiologic effect on growth and oral feeding skills. KEY POINTS: · Classical music improves the medical condition of adults.. · Music decreases neonatal resting energy expenditure.. · Music exposure did not significantly impact weight gain.. · This clinical relevance warrants further evaluation..

RESUMO

Policy Points State-level social and economic policies that expand tax credits, increase paid parental leave, raise the minimum wage, and increase tobacco taxes have been demonstrated to reduce adverse perinatal and infant health outcomes. These findings can help prioritize evidence-based legislated policies to improve perinatal and infant outcomes in the United States. CONTEXT: Rates of preterm birth and infant mortality are alarmingly high in the United States. Legislated efforts may directly or indirectly reduce adverse perinatal and infant outcomes through the enactment of certain economic and social policies. METHODS: We conducted a narrative review to summarize the associations between perinatal and infant outcomes and four state-level US policies. We then used a latent profile analysis to create a social and economic policy profile for each state based on the observed policy indicators. FINDINGS: Of 27 articles identified, nine focused on tax credits, eight on paid parental leave, four on minimum wages, and six on tobacco taxes. In all but three studies, these policies were associated with improved perinatal or infant outcomes. Thirty-three states had tax credit laws, most commonly the earned income tax credit (n = 28, 56%). Eighteen states had parental leave laws. Two states had minimum wage laws lower than the federal minimum; 14 were equal to the federal minimum; 29 were above the federal minimum; and 5 did not have a state law. The average state tobacco tax was $1.76 (standard deviation = $1.08). The latent profile analysis revealed three policy profiles, with the most expansive policies in Western and Northeastern US states, and the least expansive policies in the US South. CONCLUSIONS: State-level social and economic policies have the potential to reduce adverse perinatal and infant health outcomes in the United States. Those states with the least expansive policies should therefore consider enacting these evidence-based policies, as they have shown a demonstratable benefit in other states.

RESUMO

OBJECTIVE: This study aimed to determine if formula selection, low lactose versus standard term formula, has an effect on outcomes with a comparison to breastfed infants. STUDY DESIGN: Retrospective cohort study of neonates ≥35 weeks gestation born with Neonatal Abstinence Syndrome (NAS) was conducted from July 2014 to November 2016. Primary outcomes included length of pharmacologic treatment (LOT), and length of stay (LOS), and weight change per day comparing term standard and low lactose formula majority feeding infants with secondary outcomes comparing breast fed majority feeding infants. RESULTS: After investigating feeding methods for 249 NAS infants, a direct comparison of formula groups showed no differences in LOS (3, 95% confidence interval [CI]: -1.1 to 7 days), LOT (3.9, 95% CI: -0.4 to 8.1 days), or weight change per day (-2.4, 95% CI: -11.7 to 6.9 g/day). Breastfeeding improved LOT by 6.9 (95% CI: 3.4-10.5) and 10.8 days (95% CI: 5.9-15.6) and LOS by 7.4 (95% CI: 4.1-10.7) and 10.3 (95% CI: 5.8-14.9) days all reaching significance, in comparison to term and low lactose formula groups, respectively. Weight change per day was greater in the breast versus formula feeding groups when compared individually. CONCLUSION: We detected no benefit to low lactose formula in NAS infants. Breastfeeding is associated with clinical reduction in LOS and LOT but is associated with increased weight loss. KEY POINTS: · Best formula choice for a neonatal abstinence syndrome (NAS) infant is unknown.. · Many NAS moms cannot breastfeed.. · Low lactose formula has no impact on NAS outcomes..

RESUMO

BACKGROUND: Interventions need to be developed in a timely and relatively low-cost manner in order to respond to, and quickly address, major public health concerns. We aimed to quickly develop an intervention to support people with severe mental ill-health, that is systematic, well founded both in theory and evidence, without the support of significant funding or resource. In this article we aim to open and elucidate the contents of the 'black box' of intervention development. METHODS: A multidisciplinary team of seven academics and health practitioners, together with service user input, developed an intervention in 2018 by scoping the literature, face-to-face meetings, email and telephone. Researcher fieldnotes were analysed to describe how the intervention was developed in four iterative steps. RESULTS: In step 1 and 2, scoping the literature showed that, a) people with severe mental illness have high mortality risk in part due to high levels of sedentary behaviour and low levels of exercise; b) barriers to being active include mood, stress, body weight, money, lack of programmes and facilities and stigma c) 'nature walks' has potential as an intervention to address the problem. In Step 3, the team agreed what needed to be included in the intervention so it addressed the "five ways to mental wellbeing" i.e., help people to connect, be active, take notice, keep learning and give. The intervention was mapped to key behavioural change concepts such as, personal relevance, relapse prevention, self-efficacy. In Step 4, the team worked out how best to implement the intervention. The intervention would be delivered over 12 weeks by members of the hospital team and community walk volunteers. Participants would receive a nature walks booklet and text messages. CONCLUSIONS: We developed a theoretically-informed, evidence-based nature walks programme in a timely and relatively low-cost manner relevant in an era of growing mental illness and funding austerity. Further research is required to test if the intervention is effective and if this approach to intervention development works.

RESUMO

OBJECTIVES: Antenatal corticosteroids are standard of care for women at risk of a preterm birth and demonstrated to be protective against poor outcomes in neonates including respiratory disorders, mortality and intraventricular hemorrhage (IVH). Its benefits may vary by gestational age, and accurate estimation is needed in a single-center population to account for practice variation. METHODS: A retrospective cohort of infants admitted to the hospital's neonatal intensive care unit, 1997-2015. Using Poisson regression, we separately modeled the incidence rate ratio of death, grade III or IV intraventricular hemorrhage (IVH), and moderate to severe bronchopulmonary dysplasia (BPD) testing the moderating effects of gestation on antenatal steroids, controlling for potential confounding. RESULTS: Among 5314 infants admitted, death occurred in 298 (6%), severe IVH in 244 (5%), and BPD in 527 (10%). Antenatal steroids were protective of death and BPD in the adjusted analysis, and there was multiplicative interaction where each week increase in gestational age combined with steroid therapy resulted in 13% reduced incidence for each outcome. CONCLUSIONS FOR PRACTICE: Antenatal steroids are protective against severe IVH and moderate to severe BPD, and when combined with gestational age, steroids are associated with greater protective benefits in older neonates. There is likely an ideal window to maximize the benefits of antenatal steroids, and future etiologic research should consider the joint effects with gestational age.

RESUMO

Plant lectins through their multivalent quaternary structures bind intrinsically flexible oligosaccharides. They recognize fine structural differences in carbohydrates and interact with different sequences in mucin core 2 or complex-type N-glycan chain and also in healthy and malignant tissues. They are used in characterizing cellular and extracellular glycoconjugates modified in pathological processes. We study here, the complex carbohydrate-lectin interactions by determining the effects of substituents in mucin core 2 tetrasaccharide Galß1-4GlcNAcß1-6(Galß1-3)GalNAcα-O-R and fetuin glycopeptides on their binding to agarose-immobilized lectins PNA, RCA-I, SNA-I and WGA. Briefly, in mucin core 2 tetrasaccharide (i) structures modified by α2-3/6-Sialyl LacNAc, LewisX and α1-3-Galactosyl LacNAc resulted in regular binding to PNA whereas compounds with 6-sulfo LacNAc displayed no-binding; (ii) strucures bearing α2-6-sialyl 6-sulfo LacNAc, or 6-sialyl LacdiNAc carbohydrates displayed strong binding to SNA-I; (iii) structures with α2-3/6-sialyl, α1-3Gal LacNAc or LewisX were non-binder to RCA-I and compounds with 6-sulfo LacNAc only displayed weak binding; (iv) structures containing LewisX, 6-Sulfo LewisX, α2-3/6-sialyl LacNAc, α2-3/6-sialyl 6-sulfo LacNAc and GalNAc Lewis-a were non-binding to WGA, those with α1-2Fucosyl, α1-3-Galactosyl LacNAc, α2-3-sialyl T-hapten plus 3'/6'sulfo LacNAc displayed weak binding, and compounds with α2-3-sialyl T-hapten, α2.6-Sialyl LacdiNAc, α2-3-sialyl D-Fucß1-3 GalNAc and Fucα-1-2 D-Fucß-1-3GalNAc displaying regular binding and GalNAc LewisX and LacdiNAc plus D-Fuc ß-1-3 GalNAcα resulting in tight binding. RCA-I binds Fetuin triantennary asialoglycopeptide 100 % after α-2-3 and 25 % after α-2-6 sialylation, 30 % after α-1-2 and 100 % after α-1-3 fucosylation, and 50 % after α-1-3 galactosylation. WGA binds 3-but not 6-Fucosyl chitobiose core. Thus, information on the influence of complex carbohydrate chain constituents on lectin binding is apparently essential for the potential application of lectins in glycoconjugate research.

RESUMO

BACKGROUND: The prevalence of ventricular septal defects (VSDs), a birth defect in which there is an opening in the wall that separates the left and right ventricles of the heart, seemed to be substantially higher in Delaware compared with the National Birth Defects Prevention Network (NBDPN). The Delaware Birth Defects Registry (BDR) noted their high prevalence of VSDs in comparison with other states. METHODS: A subset of children with a VSD born in 2007 through 2010 was identified from the complete reportable statewide defect list that the BDR creates each year. VSDs were categorized by type of VSD (muscular, perimembranous, conotruncal, or atrioventricular septal defect), by either isolated or complex, and then by spontaneously closed, surgically closed, open but clinically insignificant, lost to follow-up, fetal or neonatal death. RESULTS: The BDR team found a prevalence of VSD of 83.4 per 10,000 including fetal/neonatal deaths. Excluding fetal and neonatal deaths the prevalence was 78.7 per 10,000 live births. Excluding small muscular VSDs, the prevalence in Delaware falls to 25.7 per 10,000. CONCLUSION: The BDR team chose to include all babies with all types of VSDs. Using these criteria Delaware's prevalence of 78.7 was higher than that reported by other states (whose prevalence ranges from 1.6 to 70.0 per 10,000 live births) (National Birth Defects Prevention Network, ). Delaware's prevalence is similar to other states when small muscular VSDs are excluded. Birth Defects Research (Part A) 106:888-893, 2016. © 2016 Wiley Periodicals, Inc.

RESUMO

BACKGROUND: There are limited data on parental perception of infant participation in minimal risk and minor increase above minimal risk research focusing on the NICU population. The study objective was to assess parental and NICU staff perceptions concerning minimal risk and minor increase above minimal risk in the NICU setting. METHODS: Parents of infants and NICU staff were presented with a combination of 4 infant scenarios and 5 hypothetical research procedures. These assessed participants' willingness to allow their infant to participate in research and their attitude towards obligation to assist future children. Linear and hierarchal linear models analyzed the association and interaction effects on the likelihood to consent to research procedures. RESULTS: Sixty parents and 30 NICU staff members were surveyed. Parents' acceptability for each of the five research procedures ranged from 31 % to 83 %. Parent gender, age, race/ethnicity, insurance, education and history of previous child in the NICU were not associated with the likelihood to consent to the research procedures. Acceptability for each of the five research procedures among NICU staff ranged from 19 % to 98 %. There were no significant differences between NICU staff's and parents' responses for 4 of 5 research procedures. A minority of parents and nurses (38.3 % and 40 % respectively), compared to a majority of physicians (66.7 %), agreed or strongly agreed that parents have a responsibility to involve their children in low risk medical research in order to help future children, even if this would not help their own child. Lower agreement with obligation to help future children (p < 0.01) and higher education (p = 0.01) were associated with a decreased likelihood to consent to research procedures. CONCLUSION: In our study population, common NICU-related research procedures were considered appropriate and acceptable to a diverse group of NICU parents representing a wide range of race/ethnic and socioeconomic strata. Current regulations guiding informed consent for minimal and minor increase over minimal risk research in the NICU environment appear ethically consistent with a diverse group of parents and providers.

RESUMO

BACKGROUND: Health Literacy is the ability to obtain, process, and understand health information to make knowledgeable health decisions. PURPOSE: To determine baseline health literacy of neonatal intensive care unit (NICU) parents at a tertiary care hospital during periods of crucial information exchange. METHODS: Health literacy of English-speaking NICU parents was assessed using the Newest Vital Sign (NVS) on admission (n = 121) and discharge (n = 59). A quasi-control group of well-baby nursery (WBN) parents (n = 24) and prenatal obstetric clinic (PRE) parents (n = 18) were included. A single, Likert-style question measured nurses' assessment of parental comprehension with discharge teaching. Suspected limited health literacy (SLHL) was defined as the NVS score of 3 or less. FINDINGS/RESULTS: Forty-three percent of parents on NICU admission and 32% at NICU discharge had SLHL (P < .01). SLHL for WBN and PRE parents was 25% and 58%, respectively. Parental age, gender, location, and history of healthcare-related employment were not associated with health literacy status at any time point. Thirty-nine percent of NICU parents and 25% of WBN parents with SLHL at time of admission/infant birth had a college education. Nurse subjective measurement of parental comprehension of discharge instructions was not correlated to the objective measurement of health literacy (P = .26). IMPLICATIONS FOR PRACTICE: SLHL is common during peak time periods of complex health discussion in the NICU, WBN, and PRE settings. NICU providers may not accurately gauge parents' literacy status. IMPLICATIONS FOR RESEARCH: Methods for improving health communication are needed. Studies should evaluate SLHL in a larger NICU population and across different languages and cultures.

RESUMO

OBJECTIVE: The objective of the article is to determine if > 48 hours of antibiotic treatment during the 1st week of life is associated with subsequent isolation of bacteria from the endotracheal tube (ETT), and an increased risk of bronchopulmonary dysplasia (BPD). STUDY DESIGN: Retrospective cohort study of very low birth weight infants. Routine weekly surveillance ETT cultures were obtained to monitor bacterial colonization in all intubated infants. Risk factors for BPD were assessed using unadjusted and multivariable analyses. RESULTS: In the study sample (n = 906), infants with BPD (n = 182) were more likely to have received > 48 hours antibiotic treatment (31 vs. 14%, p < 0.01) and have a resistant gram-negative bacilli in ETT (7 vs. 2%, p = 0.0001) compared with infants without BPD. Treatment with > 48 hours of antibiotics remained associated with BPD (adjusted odds ratio, 2.2; 95% confidence interval, 1.4-3.5) after controlling for confounding variables. CONCLUSIONS: Antibiotic duration > 48 hours in the 1st week of life was associated with subsequent BPD and the presence of resistant bacteria in routine ETT cultures.

RESUMO

BACKGROUND: The National Institutes of Health reported in 2007 that approximately 38% of United States adults have used at least one type of Complementary and Alternative Medicine (CAM). There are no studies available that assess general CAM use in US pregnant women.The objectives of our study were to determine the prevalence and type of CAM use during pregnancy at one medical center; understand who is using CAM and why they are using it; and assess the state of patients' CAM use disclosure to their obstetrical providers. METHODS: A cross-sectional survey study of post-partum women was done to assess self-reported CAM use during pregnancy. Results of this survey were compared to results from a previous survey performed by this research team in 2006. Data were analyzed using binary logistic regression. RESULTS: In 2013, 153 women completed the survey, yielding a response rate of 74.3%. Seventy-two percent and 68.5% of participants reported CAM use during their pregnancies in 2006 and 2013 respectively. The percentage of participants who reported discussing CAM use with their obstetrical providers was less than 1% in 2006 and 50% in 2013. Increased use of different CAM therapies was associated with increased maternal age, primagravida, being US-born, and having a college education (p ≤ 0.05). However, these factors were poor predictors of CAM use. CONCLUSIONS: Given the frequency of CAM use and the difficulty in predicting who is using it, obstetrical providers should consider being informed about CAM and incorporating discussions about its use into routine patient assessments.

RESUMO

Our previous studies suggest that the α2,3sialylated T-antigen (NeuAcα2,3Galß1,3GalNac-) and associated glycan structures are likely to be elevated during cancer. An easy and reliable strategy to label mucinous glycans that contain such carbohydrates can enable the identification of novel glycoproteins that are cancer associated. To this end, the present study demonstrates that the exchange sialylation property of mammalian ST3Gal-II can facilitate the labeling of mucin glycoproteins in cancer cells, tumor specimens, and glycoproteins in cancer sera. Results show that (i) the radiolabeled mucin glycoproteins of each of the cancer cell lines studied (T47D, MCF7, LS180, LNCaP, SKOV3, HL60, DU4475, and HepG2) is distinct either in terms of the specific glycans presented or their relative distribution. While some cell lines like T47D had only one single sialylated O-glycan, others like LS180 and DU4475 contained a complex mixture of mucinous carbohydrates. (ii) [14C]sialyl labeling of primary tumor cells identified a 25-35 kDa mucin glycoprotein unique to pancreatic tumor. Labeled glycoproteins for other cancers had higher molecular weight. (iii) Studies of [14C] sialylated human sera showed larger mucin glycopeptides and >2-fold larger mucin-type chains in human serum compared to [14C]sialyl labeled glycans of fetuin. Overall, the exchange sialylation property of ST3Gal-II provides an efficient avenue to identify mucinous proteins for applications in glycoproteomics and cancer research.

RESUMO

Novel strategies to control the binding of adhesion molecules belonging to the selectin family are required for the treatment of inflammatory diseases. We tested the possibility that synthetic monosaccharide analogs can compete with naturally occurring sugars to alter the O-glycan content on human leukocyte cell surface selectin-ligand, P-selectin glycoprotein ligand-1 (PSGL-1). Resulting reduction in the sialyl Lewis-X-bearing epitopes on this ligand may reduce cell adhesion. Consistent with this hypothesis, 50muM per-acetylated 4F-GalNAc added to the growth media of promyelocytic HL-60 cells reduced the expression of the cutaneous lymphocyte associated-antigen (HECA-452 epitope) by 82% within 2 cell doubling cycles. Cell binding to all 3 selectins (L-, E-, and P-selectin) was reduced in vitro. 4F-GalNAc was metabolically incorporated into PSGL-1, and this was accompanied by an approximately 20% reduction in PSGL-1 glycan content. A 70% to 85% reduction in HECA-452 binding epitope and N-acetyl lactosamine content in PSGL-1 was also noted on 4F-GalNAc addition. Intravenous 4F-GalNAc infusion reduced leukocyte migration to the peritoneum in a murine model of thioglycolate-induced peritonitis. Thus, the compound has pharmacologic activity. Overall, the data suggest that 4F-GalNAc may be applied as a metabolic inhibitor to reduce O-linked glycosylation, sialyl Lewis-X formation, and leukocyte adhesion via the selectins.

RESUMO

BACKGROUND: Maternal race/ethnicity, age, and socioeconomic status (SES) are important factors determining birth outcome. Previous studies have demonstrated that, teenagers, and mothers with advanced maternal age (AMA), and Black/Non-Hispanic race/ethnicity can independently increase the risk for a poor pregnancy outcome. Similarly, public insurance has been associated with suboptimal health outcomes. The interaction and impact on the risk of a pregnancy resulting in a NICU admission has not been studied. Our aim was, to analyze the simultaneous interactions of teen/advanced maternal age (AMA), race/ethnicity and socioeconomic status on the odds of NICU admission. METHODS: The Consortium of Safe Labor Database (subset of n = 167,160 live births) was used to determine NICU admission and maternal factors: age, race/ethnicity, insurance, previous c-section, and gestational age. RESULTS: AMA mothers were more likely than teenaged mothers to have a pregnancy result in a NICU admission. Black/Non-Hispanic mothers with private insurance had increased odds for NICU admission. This is in contrast to the lower odds of NICU admission seen with Hispanic and White/Non-Hispanic pregnancies with private insurance. CONCLUSIONS: Private insurance is protective against a pregnancy resulting in a NICU admission for Hispanic and White/Non-Hispanic mothers, but not for Black/Non-Hispanic mothers. The health disparity seen between Black and White/Non-Hispanics for the risk of NICU admission is most evident among pregnancies covered by private insurance. These study findings demonstrate that adverse pregnancy outcomes are mitigated differently across race, maternal age, and insurance status.

RESUMO

Pregnancy outcomes including premature birth are influenced by multiple factors including preconception health. This study was designed to assess the knowledge of various aspects of preconception health care in clinical practice in the state of Delaware. After assuring content validity, a questionnaire was provided to primary care physicians in Delaware. A total of 94 Delaware clinicians completed the survey and 96 percent indicated they should provide preconception counseling. Physicians frequently discussed some aspects of preconception care including diabetes and weight management, while other topics including reproductive life plans, vaccinations, and HIV screening were less frequently discussed. Preconception health care has been recommended by the Centers for Disease Control and Prevention to improve the health of women of childbearing age. Our data indicate a need to increase education and programs regarding preconception health to Delaware primary care physicians.

RESUMO

While glycosyltransferases are known to display unidirectional enzymatic activity, recent studies suggest that some can also catalyze readily reversible reactions. Recently, we found that mammalian sialyltransferase ST3Gal-II can catalyze the formation of CMP-NeuAc from 5'-CMP in the presence of a donor containing the NeuAcα2,3Galß1,3GalNAc unit [Chandrasekaran, E. V., et al. (2008) Biochemistry 47, 320-330]. This study shows by using [9-(3)H]- or [(14)C]sialyl mucin core 2 compounds that ST3Gal-II exchanges sialyl residues between CMP-NeuAc and the NeuAcα2,3Galß1,3GalNAc unit and also radiolabels sialyl residues in gangliosides GD1a and GT1b, but not GM1. Exchange sialylation proceeds with relative ease, which is evident from the following. (a) Radiolabeleling of fetuin was ~2-fold stronger than that of asialo fetuin when CMP- [9-(3)H]NeuAc was generated in situ from 5'-CMP and [9-(3)H]NeuAcα2,3Galß1,3GalNAcß1,3Galα-O-Me by ST3Gal-II. (b) ST3Gal-II exchanged radiolabels between [(14)C]sialyl fetuin and [9-(3)H]NeuAcα2,3Galß1,3GalNAcß1,3Galα-O-Me by generating CMP-[(14)C]- and -[9-(3)H]NeuAc through 5'-CMP; only 20.3% (14)C and 28.0% (3)H remained with the parent compounds after the sialyl exchange. The [9-(3)H]sialyl-tagged MN glycophorin A, human chorionic gonadotropin ß subunit, GlyCAM-1, CD43, fetuin, porcine Cowper's gland mucin, bovine casein macroglycopeptide, human placental glycoproteins, and haptoglobin were analyzed by using Pronase digestion, mild alkaline borohydride treatment, Biogel P6, lectin agarose, and silica gel thin layer chromatography. Sulfated and sialylated O-glycans were found in GlyCAM-1 and human placental glycoproteins. This technique has the potential to serve as an important tool as it provides a natural tag for the chemical and functional characterization of O-glycan-bearing glycoproteins.

RESUMO

BACKGROUND: Optimizing patient/family caregiver satisfaction with emergency department (ED) encounters has advantages for improving patient health outcomes, adherence with medical plans, patient rights, and shared participation in care, provider satisfaction, improved health economics, institutional market share, and liability reduction. The variables that contribute to an optimal outcome in the pediatric ED setting have been less well investigated. The specific hypothesis tested was that patient/family caregiver-provider communication and 24-hour postdischarge phone contact would be associated with an increased frequency of highest possible satisfaction scores. METHODS: A consecutive set of Press Ganey satisfaction survey responses between June and December 2009 in a large tertiary referral pediatric ED was evaluated. Press Ganey responses were subsequently linked to defined components of the electronic medical record associated with each survey respondent's ED visit to ascertain specific objective ED data. Multivariate modeling utilizing generalized linear equations was achieved to obtain a composite model of drivers of patient/caregiver satisfaction. RESULTS: Primary drivers of satisfaction and willingness to return or refer others to the ED were as follows: being informed about delays, ease of the insurance process, overall physician rating, registered nurse attention to needs, control of pain, and successful completion of postdischarge phone call to a family caregiver. Multiple wait time variables that were statistically significant in univariate modeling, including total length of time in the ED, time in waiting room, comfort of waiting room, time in treatment room, and play items, were not statistically significant once controlling for the other variables in the model. Type of insurance, race, patient age, or time of year did not influence the models. CONCLUSIONS: Achieving optimal patient/caregiver satisfaction scores in the pediatric ED is highly dependent on the quality of the interpersonal interaction and communication of ED activities. Wait time and other throughput variables are less important than perceived quality of the health interaction and interpersonal communication. Patient satisfaction has advantages greater than market share and should be considered a component of the care-delivery paradigm.

RESUMO

OBJECTIVE: Evaluate the effect of parental protective factors on parental stress at time of NICU admission and prior to discharge. STUDY DESIGN: Parents of infants born at <35 weeks gestation were approached at a single level III NICU. Consenting parents completed a questionnaire on admission and prior to infant's discharge of demographic information and three validated instruments: (1) parental stress (PSS:NICU), (2) Parents' Assessment of Protective Factors (PAPF), and (3) health literacy (PHLAT-8). RESULTS: Mean PSS:NICU Total score was 2.8 ± 0.9 (Time 1) and 2.6 ± 1.1 (Time 2). Mean PAPF scores in all subcategories were high (means >3, ±0.3-0.5) (Time 1, Time 2). There was no clinically significant association between PSS:NICU scores and PAPF or any of the other measured variables. CONCLUSION: PAPF and other commonly implicated factors were not associated with perceived self-reported parental stress at time of NICU admission and prior to discharge.

RESUMO

OBJECTIVE: To assess the feasibility of real-time monitoring of work of breathing (WOB) indices and the impact of adjusting HFNC flow on breathing synchrony and oxygen stability in premature infants. STUDY DESIGN: A prospective, observational study of infants stable on HFNC. The flow adjusted per predetermined algorithm. Respiratory inductive plethysmography (RIP) noninvasively measured WOB. A high-resolution pulse oximeter collected oxygen saturation and heart rate data. Summary statistics and mixed linear models were used. RESULTS: Baseline data for 32 infants, final analysis of 21 infants. Eighty-one percent with abnormal WOB. Sixty-two percent demonstrated 20% improvement in WOB. For infants with gestational age <28 weeks, an incremental increase in HFNC flow rate decreased WOB (p < 0.001) and improved oxygen saturation and stability (p < 0.01). CONCLUSIONS: Premature infants do not receive optimal support on HFNC. The use of a real-time feedback system to adjust HFNC is feasible and improves WOB, oxygen saturation, and oxygen stability. This technology may improve the utility of HFNC in premature infants.

RESUMO

PURPOSE: To evaluate and compare the presence of perceived paternal stress and depressive symptomatology in fathers of preterm infants over time. SUBJECTS: Fathers of NICU infants born before 30 weeks of gestation. DESIGN: Prospective convenience sample. METHODS: Consenting fathers were given 2 self-report questionnaires: Center for Epidemiologic Studies-Depression Scale (CES-D) and Parent Stressor Scale: Infant Hospitalization (PSS:IH) on 7th (time 1), 21st (time 2), and 35th (time 3) days of life. Objective measurement of illness severity was quantified by Score for Neonatal Acute Physiology. Statistical methods included generalized linear estimating equation and mixed linear modeling. MAIN OUTCOME MEASURES: Stress and depressive symptomatology in fathers of preterm infants. RESULTS: Stress scores (PSS:IH) were unchanged over time (P = .62) indicating that fathers (n = 35) remain significantly stressed. Individual subcomponents of stress (parent role alteration, infant appearance/behavior, NICU sights/sounds) also remained constant over the study period (P = .05 for each). Stress scores over time were not modified by demographic characteristics (marriage, education, insurance). Mean depressive symptomatology scores (CES-D) decreased over time (P = .04). The percentage of fathers with elevated CES-D scores (>16) decreased from a baseline 60% but did not diminish between times 2 (39%) and 3 (36%). Parent Stressor Scale: Infant Hospitalization stress scores were correlated with CES-D depressive symptomatology scores (P < .01). Socioeconomic factors influenced initial CES-D scores, but only marriage ameliorated subsequent changes in measurements. Objective measurement of infant illness (Score for Neonatal Acute Physiology) did not influence paternal CES-D or PSS:IH scores. CONCLUSION: Fathers of premature infants in a medical NICU demonstrated elevated levels of stress that persisted across time for all domains of measured stress. Paternal self-reported stress and depressive symptomatology was independent of infant illness. One third of fathers had persistently elevated CES-D scores. If these findings are representative of general NICU population, then the emotional needs of our fathers are not being fully addressed.
