Changes in aortic root dimensions post aortic root enlargement with Y-incision and modified aortotomy.

Background: Lifetime management in aortic stenosis (AS) can be facilitated by aortic root enlargement (ARE) to improve anatomy for future valve-in-valve (ViV) procedures. A mitral valve-sparing ARE technique ("Y-incision") and sinotubular junction (STJ) enlargement ("roof" patch aortotomy) allow upsizing by 3-4 valve sizes, but quantitative analysis of changes in root anatomy is lacking. Methods: Among 78 patients who underwent ARE by Y-incision technique (± roof aortotomy closure) we identified 45 patients with high-quality pre- and post-operative computed tomography angiography (CTA) scans to allow analysis of change in aortic root dimensions. Detailed measurements of the annulus/basilar ring and sinuses were performed by an expert imager on both pre- and post-operative CTAs. The basal ring was defined as the functional annulus when a bioprosthetic valve was present. Results: Average age was 65±11 years, the majority were female (29, 64%), and 9 (20%) had undergone prior aortic valve replacement (AVR). Valve upsizing was ≥3 sizes in 41 (91%). Post-operative mean basal ring diameter was larger compared to the native annular diameter (26.3 vs. 25.3 mm, P<0.01) and substantially larger than prior prosthetic valve in redo AVR (25.6 vs. 19.3 mm, P<0.001). Diameters of the sinuses at pre-operative computed tomography (CT) increased by +7.7±2.8 [right sinuses of Valsalva (R SVS)], +6.7±3.0 [left sinuses of Valsalva (L SVS)], and +6.6±2.9 mm [non-coronary sinuses of Valsalva (N SVS)]. Mean diameter of the STJ increased to 38.3±3.7 post-operative (+8.1±3.2 mm). Left main (LM) and right coronary artery (RCA) heights decreased by -6.3±3.3 and -3.7±3.4 mm respectively due to the supra-annular position of the valve, however, the post-operative valve-to-coronary (VTC) artery distances were 6.6±2.3 and 4.9±2.0 mm, respectively. Conclusion: The Y-incision root enlargement technique significantly enlarges the sinus and STJ diameters by 6-7 mm while preserving VTC distances despite upsizing by 3-4 valve sizes, resulting in post-operative anatomy that is favorable for future transcatheter aortic valve-in-surgical aortic valve (TAV-in-SAV).

Multilingual assessment of early child development: Analyses from repeated observations of children in Kenya.

In many low- and middle-income countries, young children learn a mother tongue or indigenous language at home before entering the formal education system where they will need to understand and speak a country's official language(s). Thus, assessments of children before school age, conducted in a nation's official language, may not fully reflect a child's development, underscoring the importance of test translation and adaptation. To examine differences in vocabulary development by language of assessment, we adapted and validated instruments to measure developmental outcomes, including expressive and receptive vocabulary. We assessed 505 2-to-6-year-old children in rural communities in Western Kenya with comparable vocabulary tests in three languages: Luo (the local language or mother tongue), Swahili, and English (official languages) at two time points, 5-6 weeks apart, between September 2015 and October 2016. Younger children responded to the expressive vocabulary measure exclusively in Luo (44%-59% of 2-to-4-year-olds) much more frequently than did older children (20%-21% of 5-to-6-year-olds). Baseline receptive vocabulary scores in Luo (ß = 0.26, SE = 0.05, p < 0.001) and Swahili (ß = 0.10, SE = 0.05, p = 0.032) were strongly associated with receptive vocabulary in English at follow-up, even after controlling for English vocabulary at baseline. Parental Luo literacy at baseline (ß = 0.11, SE = 0.05, p = 0.045) was associated with child English vocabulary at follow-up, while parental English literacy at baseline was not. Our findings suggest that multilingual testing is essential to understanding the developmental environment and cognitive growth of multilingual children.

Father-Inclusive Perinatal Parent Education Programs: A Systematic Review.

CONTEXT: Fathers contribute to their children's health starting at the beginning of life. Few parent education programs include fathers. Among those that do, there is little effort to report program effects on father outcomes. OBJECTIVE: In this systematic review, we examined father-inclusive perinatal parent education programs in the United States as they relate to a range of father outcomes. DATA SOURCES: The databases searched were PubMed, Cumulative Index to Nursing and Allied Health Literature, Embase, Ovid Medline, Cochrane Central Register of Controlled Trials, and PsycINFO. STUDY SELECTION: Studies were included if they included an evaluation of a parent education program and a report of father outcomes measured within 1 year of the child's birth and were conducted within the United States. DATA EXTRACTION: Of 1353 total articles, 21 met study criteria. RESULTS: The overall state of the father-inclusive perinatal parent education program literature was poor, with few interventions available to fathers. Available programs were associated with increased father involvement, coparenting relationship, partner relationship quality, father's mental health, and father's supportive behaviors. Program effects on father-infant interaction, parenting knowledge, and attitudes and parenting self-efficacy were inconclusive. Three programs emerged as best evidence-based interventions. LIMITATIONS: Risk of bias was high for many studies. Outcome variability, small sample size, and publication bias contributed to the weak evidence base. CONCLUSIONS: There is a need for more evidence-based interventions to support fathers. Clinicians play a key role in engaging fathers in early parent education programs and health care settings.

Caring for Children with Special Health Care Needs: Profiling Pediatricians and Their Health Care Resources.

Background and Objectives Pediatricians face numerous challenges in providing care for children with special health care needs (CSHCN). Few studies have described health care resources available to support pediatricians to care for CSHCN. This study investigated available resources to care for CSHCN and factors associated with having a greater proportion of CSHCN in practice. Methods We conducted a statewide survey of active members of the American Academy of Pediatrics in California to study pediatric subspecialty care access, community and office resources and practice barriers. We performed a logistic regression model on having an "above average proportion" of CSHCN in practice, adjusting for demographics, practice type (rural vs. suburban/urban) and medical resources, care satisfaction, and ease of subspecialty access. Results Our response rate was 50.2% (n = 1290); 75% of respondents reported providing some primary care services, with many primary care pediatricians caring for a high proportion of CSHCN. Pediatricians reported an average of 28% CSHCN in their practices. Rural pediatricians lacked subspecialty access (10-59% reporting no access to the various subspecialties). Factors relating to higher CSHCN in practice included being in academic medical centers and satisfaction in caring for CSHCN. Conclusions Pediatricians report lack of access to mental health services, care coordination and case management. Academic medical centers and higher physician satisfaction in care delivery for CSHCN are associated with more CSHCN in practice. Promoting ways to support pediatricians, such as practice collaboration with behavioral specialists, may be necessary to encourage primary care pediatricians to provide medical homes for CSHCN.

The Association of Fathers' Parental Warmth and Parenting Stress to Child Behavior Problems.

This study examines whether fathers' parental warmth and parenting stress were associated with behavior problems when children were approximately 36-months of age, beyond the influence of maternal behaviors. Study participants were 3,342 low-income fathers and mothers who participated in the Building Strong Families (BSF) study. Cross-sectional regression analyses indicated that for unmarried nonresidential families, fathers' parental warmth and parenting stress were associated with child internalizing behavior problems; and fathers' parenting stress only was marginally associated with child externalizing behavior problems. For consistently cohabiting residential fathers, only fathers' parenting stress was marginally associated with child internalizing behavior problems. No associations of fathers' parental warmth and parenting stress on either internalizing or externalizing behavior problems were observed in married families. Overall, study results suggest that fathers' parental warmth and parenting stress may have a modest positive association on the development of child internalizing behavior problems particularly in vulnerable families (e.g., families in which fathers were nonresidential).

Effects of a Parenting Program Among Women Who Began Childbearing as Adolescents and Young Adults.

PURPOSE: The purpose of the study was to examine whether access to an at-scale, group-based parenting education program ("Educación Inicial") had differential effects on parenting behaviors and child cognitive development according to mother's age at the birth of her first child, with a focus on adolescent mothers in rural Mexico. METHODS: This was a secondary analysis of a cluster-randomized controlled trial (n = 728 households, n = 106 communities). We conducted intent-to-treat analyses and examined the interaction between treatment group and mother's age at first birth. The primary outcomes were parenting behaviors (Family Care Indicators) and children's cognitive development (McCarthy Scales of Children's Abilities) at ages 3-5 years. RESULTS: We found that children of mothers who began childbearing in adulthood (20-30 years) scored higher on tests of cognitive development when randomized to weekly parenting support than their counterparts in the comparison group. Whereas, the children of mothers who began childbearing in adolescence (≤16 years) did not have higher scores associated with the parenting program (difference in magnitude of associations: Verbal = -8.19; 95% CI = -15.50 to -.88; p = .03; Memory = -7.22; 95% CI = -14.31 to -.14; p = .05). The higher scores among the children of mothers who began childbearing in adulthood were only significant when Educación Inical was supported by Prospera, the conditional cash transfer program. CONCLUSIONS: Our study results suggest that the Educación Inicial parenting intervention did not adequately address the needs of women who began childbearing in adolescence. One reason may be that adolescent mothers are more socially marginalized and less able to benefit from parenting programs.

Pediatricians' Comfort Level in Caring for Children With Special Health Care Needs.

BACKGROUND: Few studies have investigated pediatrician attitudes about providing primary medical care for children with special health care needs. The objective of this study was to determine pediatrician perspectives on their comfort level in providing care and on where the medical home should be for children with chronic medical and developmental conditions. METHODS: Survey of pediatricians in California in 2014. Pediatricians were randomized to receive surveys featuring either a case of a child with a chronic medical (neurofibromatosis) or a developmental condition (autism). They were then asked about their comfort level in providing primary care for the child. We developed logistic regression models to adjust for practice and provider factors, and availability of family social resources. RESULTS: The survey response rate was 50.2%. Primary care pediatricians expressed more comfort than nonprimary care pediatricians in providing a medical home for a child with chronic medical or developmental condition (range, 84%-92% comfortable vs 58%-79% comfortable), respectively. All pediatricians expressed more comfort providing care for a child with autism than neurofibromatosis. Nearly all primary care pediatricians (90%) believed that the medical home should be in pediatric primary care practice. Pediatrician comfort in becoming a medical home was higher when the family had more social resources. CONCLUSIONS: Most pediatricians endorse that the medical home for children with special health care needs be in the primary care setting. Improving access to subspecialty care and providing resources, such as case management, to address family social complexity might raise pediatrician comfort in providing primary care to children with medical and developmental conditions.

Stimulating Parenting Practices in Indigenous and Non-Indigenous Mexican Communities.

Parenting may be influenced by ethnicity; marginalization; education; and poverty. A critical but unexamined question is how these factors may interact to compromise or support parenting practices in ethnic minority communities. This analysis examined associations between mothers' stimulating parenting practices and a range of child-level (age; sex; and cognitive and socio-emotional development); household-level (indigenous ethnicity; poverty; and parental education); and community-level (economic marginalization and majority indigenous population) variables among 1893 children ages 4-18 months in poor; rural communities in Mexico. We also explored modifiers of associations between living in an indigenous community and parenting. Key findings were that stimulating parenting was negatively associated with living in an indigenous community or family self-identification as indigenous (ß = -4.25; SE (Standard Error) = 0.98; ß = -1.58; SE = 0.83 respectively). However; living in an indigenous community was associated with significantly more stimulating parenting among indigenous families than living in a non-indigenous community (ß = 2.96; SE = 1.25). Maternal education was positively associated with stimulating parenting only in indigenous communities; and household crowding was negatively associated with stimulating parenting only in non-indigenous communities. Mothers' parenting practices were not associated with child sex; father's residential status; education; or community marginalization. Our findings demonstrate that despite greater community marginalization; living in an indigenous community is protective for stimulating parenting practices of indigenous mothers.

Promoting child development through group-based parent support within a cash transfer program: Experimental effects on children's outcomes.

We examined effects on child development of a group-based parenting support program (Educación Inicial - EI) when combined with Mexico's conditional cash transfer (CCT) program (Prospera, originally Oportunidades and Progresa). This cluster-randomized trial included 204 communities (n = 1,113 children in final sample), stratified by community indigenous status, and assigned to receive either: (T0) CCT only; (T1) CCT plus availability of EI in the community; or (T2) T1 plus promotion of the EI program by the CCT program. Interviews were conducted with the mother or primary caregiver of each child at baseline (2008, children 0-18 months old), and at follow-up (2012, children 3-5 years old); the intervention began after baseline and continued for all eligible households. Cognitive development was assessed with the Extended Ages and Stages Questionnaire (baseline) and the McCarthy Scales of Children's Development (follow-up); assessors were blinded to treatment. All analyses were intention to treat. There were significant effects on child development when EI received support and promotion from the CCT program (T2 vs. T0: General Cognitive Index, ß = 3.90; 95% CI [0.51, 7.30], Verbal Score, ß = 4.28; 95% CI [0.51, 8.05], and Memory Score, ß = 4.14; 95% CI [0.62, 7.66]), effects equivalent to 0.26-0.29 SD. There were no significant benefits when the programs operated independently (T1 vs. T0). In stratified analyses, EI showed significant effects in indigenous communities only. We found consistent results in regressions controlling for covariates, with some reductions in magnitude of differences. Our findings suggest that group-based, parenting support programs can improve child outcomes within the context of a CCT, but only when the 2 programs are integrated and mutually supportive.

School Health Services for Children With Special Health Care Needs in California.

Children with special health care needs (CSHCN) are at risk for school failure when their health needs are not met. Current studies have identified a strong connection between school success and health. This study attempted to determine (a) how schools meet the direct service health needs of children and (b) who provides those services. The study used the following two methods: (a) analysis of administrative data from the California Basic Educational Data System and (b) a cross-sectional online survey of 446 practicing California school nurses. Only 43% of California's school districts employ school nurses. Unlicensed school personnel with a variety of unregulated training provide school health services. There is a lack of identification of CSHCN, and communication barriers impair the ability to deliver care. Study results indicate that California invests minimally in school health services.

The Mismatch Between Children's Health Needs and School Resources.

There are increasing numbers of children with special health care needs (CSHCN) who require various levels of care each school day. The purpose of this study was to examine the role of public schools in supporting CSHCN through in-depth key informant interviews. For this qualitative study, the authors interviewed 17 key informants to identify key themes, provide recommendations, and generate hypotheses for further statewide survey of school nurse services. Key informants identified successful strategies and challenges that public schools face in meeting the needs of all CSHCN. Although schools are well intentioned, there is wide variation in the ability of schools to meet the needs of CSHCN. Increased funding, monitoring of school health services, integration of services, and interagency collaboration are strategies that could improve the delivery of health services to CSHCN in schools.

Systolic flow displacement correlates with future ascending aortic growth in patients with bicuspid aortic valves undergoing magnetic resonance surveillance.

OBJECTIVES: Altered systolic blood flow in the ascending aorta has been correlated with increased aortic growth in patients with bicuspid aortic valves (BAVs). We used conventional, 2-dimensional (2D) phase contrast magnetic resonance imaging (PC-MRI) to assess the relationship between altered flow and future growth in patients with BAV. MATERIALS AND METHODS: Aortic MRI data were reviewed for 17 adult patients with BAV with right-left leaflet fusion undergoing surveillance imaging who had 2D PC-MRI through their ascending aortas on an initial study, follow-up studies more than 1 year later, and an initial maximum aortic diameter of less than 4.5 cm. Diameters were measured at standard levels by 2 blinded reviewers. Normalized systolic flow displacement was calculated at peak systole from the PC-MRI data, and correlation with the interval aortic growth was performed, with adjustment for clinical/demographic factors. RESULTS: The average follow-up interval was 2.9 ± 1.3 years. Systolic flow displacement at the initial study strongly correlated with ascending aortic growth rate (r = 0.71, P < 0.005) with moderate, non-significant correlation between initial diameter and growth (r = 0.45, P = 0.214). Aortic growth was 4 times faster in patients with initial flow displacement of 0.2 or greater (n = 9) compared with those (n = 8) with initial flow displacement less than 0.2 (0.8 ± 0.4 vs 0.2 ± 0.3 mm/y; P = 0.002). CONCLUSIONS: Systolic flow displacement calculated from conventional 2D PC-MRI in the ascending aorta correlates with future aortic growth in patients undergoing routine surveillance imaging for BAV. With a cutoff valve of 0.2, flow displacement may be used to identify a subset of patients likely to have elevated growth rates and may better risk-stratify patients with BAV for aortic disease progression than vessel diameter alone.

Maternal methadone dosing schedule and fetal neurobehaviour.

OBJECTIVE: Daily methadone maintenance is the standard of care for opiate dependency during pregnancy. Previous research has indicated that single-dose maternal methadone administration significantly suppresses fetal neurobehaviours. The purpose of this study was to determine if split-dosing would have less impact on fetal neurobehaviour than single-dose administration. METHODS: Forty methadone-maintained women were evaluated at peak and trough maternal methadone levels on single- and split-dosing schedules. Monitoring sessions occurred at 36- and 37-weeks gestation in a counterbalanced study design. Fetal measures included heart rate, variability, accelerations, motor activity and fetal movement-heart rate coupling (FM-FHR). Maternal measures included heart period, variability, skin conductance, respiration and vagal tone. Repeated measure analysis of variance was used to evaluate within-subject changes between split- and single-dosing regimens. RESULTS: All fetal neurobehavioural parameters were suppressed by maternal methadone administration, regardless of dosing regimen. Fetal parameters at peak were significantly lower during single versus split methadone administration. FM-FHR coupling was less suppressed from trough to peak during split-dosing versus single-dosing. Maternal physiologic parameters were generally unaffected by dosing condition. CONCLUSION: Split-dosed fetuses displayed less neurobehavioural suppression from trough to peak maternal methadone levels as compared with single-dosed fetuses. Split-dosing may be beneficial for methadone-maintained pregnant women.
