Multi-Level Protective and Risk Factors Longitudinally Associated with Dating Violence Perpetration among Non-Urban Mexican-American Adolescents

To assess the longitudinal relationship between individual and interpersonal risk and protective factors and dating violence perpetration among non-urban Mexican-American youth. With data from a 24-month prospective cohort study (2015-2019; baseline recruitment spanned from 2015-2017; four follow-up interviews every 6 months) of Mexican-American youth (8th grade at baseline) living in an agricultural region (Salinas, California), we utilized multivariable modified Poisson general estimating equations stratified by gender (n = 489) to assess the relationships of religiosity, non-violent problem-solving skills, school connectedness, family cohesion, and bullying victimization with dating violence perpetration. Among girls, but not boys, non-violent problem-solving skills [adjusted relative risk (ARR): 0.7; 95% confidence interval (CI): 0.56-0.99] and family cohesion (ARR: 0.7; 95% CI: 0.48-0.97) were negatively associated with dating violence perpetration, and frequency of bullying victimization was positively associated (ARR: 1.9; 95% CI: 1.37-2.59). Non-urban Mexican-American female youth may benefit from multi-level dating violence prevention that strengthens family cohesion by building upon the Mexican-American cultural value of familismo and addresses common risk factors for bullying and dating violence perpetration. Additionally, results affirm etiological differences between girls' and boys' dating violence perpetration and the need for improved measurement.

Social environment risk factors for violence, family context, and trajectories of social-emotional functioning among Latinx adolescents

INTRODUCTION

High social-emotional functioning, including emotion regulation and nonviolent conflict resolution, constitute developmental competencies of adolescence that promote health and well-being. We used prospective longitudinal data from a predominantly Latinx population to understand how family context and social environment risk factors for violence related to patterns of social-emotional functioning during the transition between middle school and high school.

METHODS

We prospectively interviewed 599 8th graders every 6 months for 2 years. We used trajectory models to explore longitudinal patterns of emotion regulation and nonviolent problem solving and multinomial regression to distinguish how these groups were associated with family context, partner and peer gang involvement, and neighborhood social disorder.

RESULTS

Youth reporting lower neighborhood disorder in 8th grade were more likely to be in the high emotion regulation trajectory group. Youth without exposure to gangs through peers and partners in 8th grade were more likely to be in the high nonviolent problem-solving skills trajectory group. Family cohesion was associated with being in the high trajectory groups for both emotional regulation and problem-solving skills.

CONCLUSION

Emotion regulation and nonviolent problem-solving skills had different associations with the social environment risk factors for violence examined, indicating that mechanisms of influence and strategies for intervention may vary. The association between problem-solving skills and exposure to gangs through peers and partners shows that social norms may be important targets of change. Additionally, interventions with parents that build family cohesion during adolescence may buffer environmental exposures that shape adolescents' ability to practice protective social-emotional behaviors.

Early Sexual Debut and Neighborhood Social Environment in Latinx Youth

OBJECTIVES

To examine whether social aspects of the neighborhood environment are associated with early sexual initiation in a California agricultural community of predominantly Latinx adolescents.

METHODS

In a prospective cohort study of 599 eighth graders recruited from middle schools in Salinas, California (2015-2019), participants completed five interviews over 2 years. Social environment measures included neighborhood social dynamics (neighborhood disorder, social cohesion, and social network gang exposure); experiences of discrimination; and school connectedness. We estimated associations between baseline social environment and early sexual initiation (<15 years) using Poisson regression with robust standard errors. We compared contraceptive self-efficacy and attitudes by sexual initiation status using ANOVA.

RESULTS

Most youth were Latinx (94%) and age 13 (70%) at enrollment; 53% were female and 49% had a parent employed in agriculture. Additionally, 14% reported first vaginal sex before age 15. Neighborhood disorder (relative risk [RR], 1.13; 95% confidence interval [CI], 1.05-1.21), social network gang exposure (RR, 2.23; 95% CI, 1.49-3.33), and experiences of discrimination (RR, 1.67 [1-2 events versus none], 95% CI, 1.09-2.55; RR, 2.33 [3+ events versus none], 95% CI, 1.07-4.64) were associated with early sexual initiation. School connectedness was protective (RR, 0.44, 95% CI, 0.29-0.69). Youth who initiated sex before age 15 had more negative birth control attitudes and expressed lower motivation to use contraceptives.

CONCLUSIONS

Findings underscore opportunities to promote early adolescent sexual health through strengthening supportive and safe neighborhood environments with the promise of addressing disparities in unintended pregnancy and sexually transmitted infection rates in later adolescence.

Community-engaged Research with Rural Latino Adolescents: Design and Implementation Strategies to Study the Social Determinants of Health

The health of adolescents, perhaps more than in any other period of their life, is shaped by the social determinants of health (SDH). The constellation of SDH that disadvantages a specific group's health may also make members of that population unable or unwilling to engage in health research. To build a comprehensive body of knowledge about how SDH operate within a specific social context, researchers must design studies that take into account how various vulnerabilities and oppressions may affect people's experiences of being recruited, interviewed and retained in a study. In 2014, we initiated a prospective cohort study with Latino youth living in the agricultural area of Salinas, California. We began this study with the understanding that it was imperative to develop methodological strategies that actively addressed potential challenges in ways that were culturally responsive, community engaged and inclusive. In this article, we describe our approach to developing best practices in four key areas: 1) building community partnerships and engagement; 2) consideration of staffing and staff support; 3) engaging youth's perspectives; and 4) developing culturally appropriate research protocols. In our sample of 599 participants, nearly all youth identify as Latinx (94 per cent), half (49 per cent) have at least one parent employed as a farmworker, 60 per cent reside in crowded housing conditions, and 42 per cent have mothers who did not complete high school. Given these multiple vulnerabilities, we view a robust number of youth expressing interest in study participation, the willingness of their parents to permit their children to be enrolled, and the achievement of an ambitious sample target as evidence that our efforts to undertake best practices in community-engaged and inclusive research were well received.

Building social capital to promote adolescent wellbeing: a qualitative study with teens in a Latino agricultural community

Background

Latino youth, particularly in rural settings, experience significant disparities in rates of teen pregnancy and violence. Few data are available regarding social and structural influences on Latino youth’s developmental trajectories, specifically on factors that promote wellbeing and protect them from engagement in high-risk sexual and violence-related behaviors.

Methods

Forty-two youth aged 13 to 19 years old were recruited from middle schools and youth leadership programs to participate in one of eight community-based focus groups in Salinas, a predominantly Latino, urban center in California’s rural central coast. Focus groups covered youths’ experiences with the risk and protective factors associated with exposure to violence and romantic relationships. Four researchers completed coding with a Grounded Theory approach, informed by the theoretical frameworks of the social ecological model and social capital. The study’s design and participant recruitment were informed by a community advisory board of local youth-serving organizations and health care providers.

Results

Participants described family lives rich in bonding social capital, with strong ties to parents and near-peer family members. They reported that while parents had a strong desire to promote healthful behaviors and social mobility, they often lacked the bridging or linking social capital required to help youth navigate structural systems, such as college applications and access to confidential health care. Youth also reported that some families link their children to negative social capital, such as exposure to gang affiliation.

Conclusion

Adolescents in this agricultural community identified robust sources of bonding social capital within their families. However, they identified limitations in their families’ capacities to link them to structural resources in education, employment, and health care that could support healthful behaviors and upward social mobility.

Ophthalmic, clinical and visual electrophysiological findings in children born to mothers prescribed substitute methadone in pregnancy

BACKGROUND AND AIMS

There are growing concerns regarding visual outcome of infants exposed to opiates (including substitute methadone) and/or benzodiazepines in utero. We describe the combined ophthalmology and visual electrophysiology findings in 20 infants and children who had been exposed to substitute methadone and other drugs of misuse in utero.

METHODS

This was a descriptive case series of 20 patients, all of whom had been referred to a paediatric visual electrophysiology service because of concerns regarding visual function, and all of whom had been exposed to methadone in utero. All children underwent a full ophthalmic and orthoptic examination as well as visual electrophysiology testing deemed appropriate on an individual basis. A review was undertaken of paediatric case notes and of maternal antenatal urine toxicology.

RESULTS

Ophthalmic abnormalities included reduced acuity (95%), nystagmus (70%), delayed visual maturation (50%), strabismus (30%), refractive errors (30%), and cerebral visual impairment (25%). Visual electrophysiology was abnormal in 60%. A quarter of the children had associated neurodevelopmental abnormalities. The majority of children with nystagmus (79%) had been treated for neonatal abstinence syndrome (NAS).

CONCLUSION

Infants born to drug-misusing mothers prescribed methadone in pregnancy are at risk of a range of visual problems, the underlying causes of which are not clear. Those infants with NAS severe enough to receive pharmaceutical treatment may be at particular risk of developing nystagmus. The inclusion of visual electrophysiology in comprehensive visual assessment of children exposed to substance misuse in utero may help clarify the underlying causes by differentiating abnormalities of retinal and cortical origin.

Drug misuse in pregnancy: losing sight of the baby?

Maternal drug misuse can seriously affect the health of the fetus and newborn infant. The association of maternal drug misuse with prematurity, intrauterine growth restriction (IUGR) and neonatal abstinence syndrome (NAS) is well recognised, and there is growing concern about infant visual development and longer-term neurodevelopmental outcome. Drug misuse is associated with changes in the visual system as measured by the visual evoked potential (VEP) in adults and animal models. A recent study has shown abnormal VEPs in newborn infants exposed to methadone in utero, consistent with reports of delayed visual development in this population. Since visual abnormalities and neurodevelopmental abnormalities can be predicted by abnormal VEPs in infancy, it is postulated that the VEP may be a valuable tool in the detection of the adverse effects of maternal drug misuse upon the infant. This review summarises the impact of maternal drug misuse upon the health of the fetus and newborn infant, addresses the specific effects of maternal drug misuse upon the developing visual system and discusses the potential role of the VEP in the assessment of these infants.

Visual evoked potentials in infants exposed to methadone in utero

We investigated the effects of maternal drug misuse on neonatal visual evoked potentials (VEPs). Flash VEPs were recorded within 4 days of birth from 21 term infants of mothers misusing drugs and prescribed substitute methadone and 20 controls. Waveforms were classified as typical, atypical, immature or non-detectable, and amplitude and latencies were measured. VEPs from drug-exposed infants were less likely to be of typical waveform and more likely to be immature or non-detectable (p<0.01) than those of control infants. They were also smaller in amplitude (median 10.8 vs 24.4 microV, p<0.001). VEPs of drug-exposed infants had matured after 1 week but remained of lower amplitude than VEPs of newborn controls (p<0.01) and were non-detectable in 15%. Flash VEPs differ between maternal drug-exposed and non-drug-exposed newborns. Future research should address the specific effects of maternal methadone and/or other illicit drug misuse on infant VEPs, and associations between neonatal VEPs and subsequent visual development.

Virtual elimination of necrotising enterocolitis for 5 years - reasons?

A standardised feeding regimen was adopted in 1997 for guiding enteral feeding of neonates <32 weeks' gestation during clinical trials (18 months each) involving erythromycin (n=73) as a prokinetic and carboxymethylcellulose (n=70) as a laxative as well as for during 2 years (n=155) without any trials. Most aspects of the feeding regimen (e.g., milk increments-total volume/day, use of breast milk by choice, etc) were not significantly different from current practices.

RESULTS

298 neonates <32 weeks' gestation (<28 weeks; n=78) were enterally fed during the 5 years. Their demographic characteristics and median (interquartile) age in days at starting (AST) and days to reach full enteral feeds (FFT) of 150 ml/kg/day were not significantly different during these 5 years: [AST: 5 (3-7.5)], [FFT: 4 (3-7)] Only one case of definite NEC (> or =Stage II) occurred during the 5 years. The time to reach full feeds was also reduced by over 54% (including for neonates <28 weeks gestation) compared with a historical cohort.

CONCLUSION

Sustained reduction in the time to reach full feeds with virtual elimination of > or =Stage II NEC for 5 years indicates continued benefits of a standardised feeding regimen as a simple preventive strategy to prevent NEC. Whether our specific policy of no enteral feeds in presence of hemodynamic instability associated with PDA requiring indomethacin, and/or sepsis played a role in achieving the significant results needs controlled trials.

Use of magnifying lens to aid neonatal umbilical arterial catheter insertion

We conducted this trial to test the hypothesis that use of a magnifying lens would facilitate umbilical arterial catheter (UA C) insertion in neonates. Neonates <33 weeks' gestation requiring a UA C were randomized to conventional method of catheter insertion or an experimental method using a 2.0 X magnifying lens mounted on a headband. A total of 44 neonates (Conventional = 23, Experimental = 21) with comparable demographic characteristics completed the study. The time taken for (primary outcome) and rate of successful UAC insertion (secondary outcome) were not significantly different between the two groups (median times: conventional: 88 seconds,experimental: 70 seconds, P = 0. 734) (Success rate: conventional: 19/23 (83%) vs experimental:13/21 (63%), P = 0. 1791 Thus, our hypothesis was rejected.

Neonatal genital prolapse

Genital prolapse is a rare condition in neonates. It is most commonly associated with neural tube defects such as spina bifida. A preterm, growth restricted neonate with genital prolapse without an associated central nervous system anomaly is reported. The risk factors, management and outcome of neonatal genital prolapse are reviewed. The importance of in utero undernutrition as a predisposing factor is emphasized.

Congenital arhinia

Congenital absence of the nose or arhinia is a rare defect of embryogenesis, often associated with other anomalies. It is potentially a life-threatening condition and requires the presence of a highly skilled neonatal resuscitation team at the time of delivery. The associated anomalies often have a significant impact on the immediate as well as long-term outcome of the neonate. Parental counselling is thus vital and a multidisciplinary team approach is required to optimise the neonatal outcome. A neonate with congenital arhinia is reported and the literature reviewed to suggest guidelines for the management of such cases.
