Electronic Heart (ECG) Monitoring at Birth and Newborn Resuscitation.

BACKGROUND: Approximately 10% of newborns require assistance at delivery, and heart rate (HR) is the primary vital sign providers use to guide resuscitation methods. In 2016, the American Heart Association (AHA) suggested electrocardiogram in the delivery room (DR-ECG) to measure heart rate during resuscitation. This study aimed to compare the frequency of resuscitation methods used before and after implementation of the AHA recommendations. METHODS: This longitudinal retrospective cohort study compared a pre-implementation (2015) cohort with two post-implementation cohorts (2017, 2021) at our Level IV neonatal intensive care unit. RESULTS: An initial increase in chest compressions at birth associated with the introduction of DR-ECG monitoring was mitigated by focused educational interventions on effective ventilation. Implementation was accompanied by no changes in neonatal mortality. CONCLUSIONS: Investigation of neonatal outcomes during the ongoing incorporation of DR-ECG may help our understanding of human and system factors, identify ways to optimize resuscitation team performance, and assess the impact of targeted training initiatives on clinical outcomes.

Laryngeal mask use during neonatal resuscitation at birth: A United States-based survey of neonatal resuscitation program providers and instructors.

Aim: Neonatal resuscitation guidelines promote the laryngeal mask (LM) interface for positive pressure ventilation (PPV), but little is known about how the LM is used among Neonatal Resuscitation Program (NRP) Providers and Instructors. The study aim was to characterize the training, experience, confidence, and perspectives of NRP Providers and Instructors regarding LM use during neonatal resuscitation at birth. Methods: A voluntary anonymous survey was emailed to all NRP Providers and Instructors. Survey items addressed training, experience, confidence, and barriers for LM use during resuscitation. Associations between respondent characteristics and outcomes of both LM experience and confidence were assessed using logistic regression. Results: Between 11/7/22-12/12/22, there were 5,809 survey respondents: 68% were NRP Providers, 55% were nurses, and 87% worked in a hospital setting. Of these, 12% had ever placed a LM during newborn resuscitation, and 25% felt very or completely confident using a LM. In logistic regression, clinical or simulated hands-on training, NRP Instructor role, professional role, and practice setting were all associated with both LM experience and confidence.The three most frequently identified barriers to LM use were insufficient experience (46%), preference for other interfaces (25%), and failure to consider the LM during resuscitation (21%). One-third (33%) reported that LMs are not available where they resuscitate newborns. Conclusion: Few NRP providers and instructors use the LM during neonatal resuscitation. Strategies to increase LM use include hands-on clinical training, outreach promoting the advantages of the LM compared to other interfaces, and improving availability of the LM in delivery settings.

Validation and Feasibility of the Postnatal Growth and Retinopathy of Prematurity Retinal Screening Criteria at a Level IV Tertiary Care Neonatal Intensive Care Unit.

OBJECTIVE: Retinopathy of prematurity (ROP) is detected in preterm infants by standardized screening programs, but in general, they have poor sensitivity. The Postnatal Growth and Retinopathy of Prematurity (G-ROP) algorithm uses weight gain to predict ROP superior reported sensitivity. Our objectives are to (1) independently validate the sensitivity of G-ROP criteria for the detection of ROP in infants born at >28 weeks' gestation in a tertiary care unit in the United States and (2) to calculate the cost savings associated with a potential reduction in examinations. STUDY DESIGN: This is a retrospective analysis of retinal screening examination data, with post-hoc application of G-ROP criteria to determine whether G-ROP criteria had acceptable sensitivity and specificity in diagnosing Type 1 and Type 2 ROP. All infants born at >28 weeks who were screened by current American Academy of Pediatric Ophthalmologists/American Academy of Pediatrics guidelines at Oklahoma Children's Hospital at the University of Oklahoma Health Sciences Center, between 2014 and 2019, were included. Subset analysis of infants screened by second tier criteria was also performed. Potential cost savings were estimated by analyzing frequency of billing codes. And by calculating the number of infants who could have potentially been spared examination. RESULTS: The G-ROP criteria had 100% sensitivity in detecting type 1 and 87.6% sensitivity in detecting type 2 ROP, which would have reduced infants screened by 50%. All infants in the second tier who would require treatment were detected. A cost saving of 49% was projected. CONCLUSION: The G-ROP criteria are easy to apply in real-world setting, thus establishing feasibility. The algorithm identified all cases of type 1 ROP; however, some cases of type 2 ROP were not detected. The annual savings in hospital examination cost by using these criteria would be 50%. Therefore, G-ROP criteria can safely be used to screen for ROP and may reduce the number of unnecessary examinations. KEY POINTS: · The G-ROP screening criteria are safe and predict 100% of treatment warranted ROP.. · Adoption of G-ROP criteria is feasible for level IV NICUs.. · Adoption of G-ROP screening guidelines will result in significant cost savings..

Laryngeal Mask Use in the Neonatal Population: A Survey of Practice Providers at a Regional Tertiary Care Center in the United States.

OBJECTIVE: The aim of this study was to evaluate the level of training, awareness, experience, and confidence of neonatal practice providers in the use of laryngeal mask (LM), and to identify the barriers in its implementation in the neonatal population. STUDY DESIGN: Descriptive observational study utilizing an anonymous online questionnaire among healthcare providers at the Oklahoma Children's Hospital who routinely respond to newborn deliveries and have been trained in the Neonatal Resuscitation Program (NRP). Participants included physicians, trainees, nurse practitioners, nurses, and respiratory therapists. RESULTS: Ninety-five participants completed the survey (27.5% response rate). The sample consisted of 77 NRP providers (81%), 11 instructors (12%), and 7 instructor mentors (7%). Among 72 respondents who had undergone LM training, 51 (54%) had hands-on manikin practice, 4 (4%) watched the American Academy of Pediatrics (AAP) NRP educational video, and 17 (18%) did both. Nurses (39 out of 46) were more likely to have completed LM training than were physicians (31 out of 47). With only 11 (12%) participants having ever placed a LM in a newly born infant, the median confidence for LM placement during neonatal resuscitation was 37 on a 0 to 100 scale. Frequently reported barriers for LM use in neonates were limited experience (81%), insufficient training (59%), preference for endotracheal tube (57%), and lack of awareness (56%). CONCLUSION: While the majority of the neonatal practice providers were trained in LM placement, only a few had ever placed one in a live newborn, with a low degree of confidence overall. Future practice improvement should incorporate ongoing interdisciplinary LM education, availability of LM in the labor and delivery units, and promotion of awareness of LM as an alternative airway. KEY POINTS: · LM is underutilized as an alternative airway.. · Insufficient experience and training limit LM use.. · Providers confidence with LM placement is low..

Medical Marijuana Legalization in Oklahoma: Effects on Neonatal Exposure to Opiates.

OBJECTIVE: The U.S. opioid epidemic has been characterized by increases in opioid misuse, overdose deaths, and neonatal opioid withdrawal syndrome. Research suggests that marijuana legalization has contributed to decreased use of opiates, although many studies had methodological weaknesses and failed to address the pregnant population. Implementation of medical cannabis laws has the potential to reduce maternal opioid use and, therefore, neonatal exposure to the drugs. This study aimed to examine the association between Oklahoma's implementation of state medical marijuana laws and the neonatal exposure to opioids. STUDY DESIGN: Electronic medical records at two sites (Oklahoma City and Lawton) were searched for results of cord, urine, and meconium screens to detect amphetamines, barbiturates, benzodiazepines, cocaine, ethanol, opiates, phencyclidine, and tetrahydrocannabinol (THC). Two study periods were compared: 19 months before Oklahoma's medical marijuana law took effect and 19 months after legalization began. RESULTS: A total of 16,804 babies were born alive at the two sites during the study period. The rate of positive THC tests per 1,000 liveborn infants significantly increased from 16.2 per 1,000 during the prelaw period to 22.2 per 1,000 during the postlaw period (p = 0.004). Neonatal opioid exposure incidence showed a nonsignificant decrease from 7.6 positive tests per 1,000 liveborn infants to 6.8 per 1,000 from prelaw to postlaw period (p = 0.542). The number of positive tests for THC and concomitant use of opioids doubled from the prelaw period (n = 4) to postlaw (n = 9), but there were too few cases for statistical significance. Infants at the more rural site had significantly higher rates for amphetamines, benzodiazepines, and THC, with a trend toward higher rates for opiates. CONCLUSION: Marijuana legalization was related to significant increases in positive test rates for THC, but no significant change/association was noted for neonatal exposure to opioids. KEY POINTS: · Prior studies have not examined neonatal exposure to opioids following marijuana legalization.. · Oklahoma's new law led to higher neonatal marijuana exposure.. · Legalization of medical marijuana did not change Oklahoma's neonatal opioid positivity rate..

Multicenter study assessing physicians' and transport teams' attitudes and expectations about utilizing telemedicine to manage critical neonatal transports.

BACKGROUND: Managing critically ill neonates has unique challenges, and the transport team plays an important role in stabilizing and facilitating the transfer of these neonates from lower-level nurseries to tertiary centers, and the use of telemedicine in transport (tele-transport) can potentially benefit patient care. We conducted a multicenter study to assess the readiness for utilizing telemedicine as an adjunct to guide the care of critically ill neonates among physicians and transport team members (TTMs). This is the first multicenter study that explored physicians' and TTMs' perceptions of telemedicine usage and its value in neonatal transport. METHODS: A confidential, voluntary survey on pre-implementation attitudes toward telemedicine usage during neonatal transport was conducted as part of a quality improvement initiative. This survey involved physicians and TTMs from four academic institutions whose responses were entered into an online survey using REDCap®. The survey inquired about satisfaction with the current practice of phone consultation and the perception of using telemedicine to optimize the management of neonates during transport. RESULTS : The overall response rate for the survey was 60.1%; 82 of 127 (64.6%) physicians and 64 of 116 (55.2%) TTMs responded to the surveys. Half of the physicians and less than one-fourth of the TTMs had prior experience with telemedicine other than that used on neonatal transport. TTMs expressed greater concern about the inconvenience of video (55% vs. physicians 35% agree or strongly agree) and its time consumption (84% vs. physicians 50%). More than 70% of physicians and less than half of TTMs endorsed the potential for added value and quality improvement with video capability. Almost half of TTMs reported concern about video calls reducing their autonomy in patient care. Physicians expressed confidence in management decisions they would make after video calls (72% confident or very confident) and less confidence (49%) about both the phone assessment by TTMs and their decisions based on phone assessment. In contrast, TTMs were confident or very confident (94%) in both sharing their assessment over the phone and executing patient management after a phone call, compared with 70% for decisions made after video calls. CONCLUSIONS : Physicians and TTMs had distinct opinions on the use of telemedicine during neonatal transport. Physicians were more likely than TTMs to agree with statements about the potential for improving quality of care, while TTMs were more likely than physicians to say video calls would be time-consuming and inconvenient. We speculate some differences may stem from the TTMs' concern about losing their autonomy. Therefore, during implementation, it is critical for physicians and TTMs to agree on a shared mental model of indications for telemedicine during transport and its value to the patient care.

Maternal-Fetal Immunologic Response to SARS-CoV-2 Infection in a Symptomatic Vulnerable Population: A Prospective Cohort.

BACKGROUND: Coronavirus disease 2019 (COVID-19) disproportionally affects pregnant women and their newborn; however, little is known about variables that modulate maternal-fetal immune response to infection. METHODS: We prospectively studied socioeconomic, biologic, and clinical factors affecting humoral immunity in 87 unvaccinated pregnant women hospitalized in Buenos Aires for symptoms consistent with COVID-19. RESULTS: The number of days between symptom onset and childbirth predicted maternal and newborn virus spike protein receptor binding domain (RBD)-specific immunoglobulin G (IgG). These findings suggest newborns may benefit less when mothers deliver soon after COVID-19 infection. Similarly, a longer time between symptom onset and birth predicted higher in utero transfer of maternal IgG and its concentration in cord blood. Older gestational age at birth was associated with lower maternal to cord blood IgG ratio. Of women with confirmed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, 87% developed RBD-specific IgA responses in breast milk within 96 hours of childbirth. IgA was not significantly associated with time from infection but correlated with maternal serum IgG and placental transfer. CONCLUSIONS: These results demonstrate the combined role of biologic, clinical, and socioeconomic variables associated with maternal RBD-specific antibodies and supports early vaccination strategies for COVID-19 in socioeconomically vulnerable pregnant women.

Menstrual Patterns Among Patients With Anorexia Nervosa and Avoidant/Restrictive Food Intake Disorder: Does "Junk Food" Play a Role?

PURPOSE: Few studies have examined menstrual differences between patients with anorexia nervosa (AN) versus avoidant/restrictive food intake disorder (ARFID). After observing that many patients with ARFID maintain regular menses despite weight loss, we sought to characterize these menstrual differences in the context of specific eating behaviors. METHODS: Patients with AN or ARFID in a disordered eating database at the University of Oklahoma Health Sciences Center were included. Bivariate analyses explored group differences in demographics, age, percentage of median body mass index for age (%mBMI), time since last menstrual period (LMP), and reported eating behaviors, including whether self-reported diet history included "junk food" consumption in the past 24 hours. Regression analysis examined whether diagnosis and variables that were associated with diagnosis significantly predicted time since LMP. RESULTS: The analyses included 89 participants diagnosed with AN or ARFID (AN: n = 70; ARFID: n = 19). The AN group had higher %mBMI for age than the ARFID group (83.4% vs 76.4%, respectively, P = .004) and was less likely to have reported consuming junk food the day prior (36.8% vs 76.5%, respectively, P = .003). Time since LMP was longer for those with AN versus ARFID (174 vs 13 days, respectively, P < .0001). A 2-predictor model with diagnosis and junk food explained a significant proportion of variance in time since LMP (P = .012). CONCLUSION: This paper may be the first to describe menstrual differences among individuals with AN and ARFID in the context of eating behaviors. In addition to diagnosis, having no self-reported junk food consumption in the past 24 hours was significantly associated with longer time since LMP. Studies that include specific measures of food intake and hormonal responses to food quality are warranted to further explore the etiology of menstrual differences among patients with AN and ARFID.

Tele-Echocardiography for Congenital Heart Disease Screening in a Level II Neonatal Intensive Care Unit with Hybrid Telemedicine System.

Introduction: The nationwide shortage of pediatric cardiologists in medically underserved areas poses a challenge to congenital heart disease (CHD) screening requiring echocardiography, resulting in transfer of neonates to regional Level III/IV Neonatal Intensive Care Units (NICUs). This study aimed to evaluate the accuracy, safety, and cost-effectiveness of tele-echocardiography for advanced CHD screening at a Level II NICU managed by a hybrid telemedicine system. Methods: Retrospective chart review of infants requiring tele-echocardiography at a Level II NICU. Patient demographics, echocardiography indications, and findings were analyzed. Agreement between tele-echocardiography and conventional echocardiography findings was assessed. Transport cost savings were calculated based on preventable transfers to Level IV NICU. Descriptive statistics were computed for demographic and clinical variables. Results: Over 5 years, 52 infants were screened for CHD. Thirty-two infants (62%) had findings consistent with minor CHD or normal neonatal transitional physiology. Twenty infants (38%) had abnormal findings requiring follow-up with either a conventional echocardiography as inpatient at the regional Level IV NICU or as outpatient after discharge. Only 5 infants (10%) required transfer to a Level IV NICU for CHD management, whereas 15 infants (29%) were scheduled for outpatient follow-up. Strong agreement was noted between tele-echocardiography and conventional echocardiography findings. No case of critical congenital heart disease (CCHD) was missed. Tele-echocardiography saved $260,000 in transport costs. Conclusions: Tele-echocardiography can be accurate, safe, and effective in CHD screening, preventing unnecessary transfer of most infants to regional Level III/IV NICUs, saving transfer costs.

Using Relaxation and Guided Imagery to Address Pain, Fatigue, and Sleep Disturbances: A Pilot Study.

BACKGROUND: Few studies have been conducted on the use of patient-controlled relaxation and guided imagery interventions for the symptom cluster of pain, fatigue, and sleep disturbance during cancer treatment. OBJECTIVES: The primary aim of this study was to evaluate the feasibility, acceptability, and participant satisfaction with use of patient-controlled relaxation and/or imagery interventions for pain, fatigue, and sleep disturbance. A secondary aim was to examine the data for trends in pain, fatigue, and sleep improvement because of the effects of relaxation and guided imagery. METHODS: Twelve adult patients with cancer were randomized to one of four groups. FINDINGS: Patients reported a high degree of satisfaction with the relaxation and guided imagery interventions. Patients in the relaxation and guided imagery or combined groups showed a trend toward improvement in fatigue and sleep disturbance scores. Pain remained a problem for the majority of patients. Difficulties in recruiting participants resulted in an insufficient sample size for generalizable findings. With hospital environments tending to be noisy, relaxation and guided imagery may facilitate rest and sleep for hospitalized patients. An examination of individual scores showed a trend toward improvement in sleep quality.

Weight-Bearing Exercise and Foot Health in Native Americans.

Diabetes contributes to sensory peripheral neuropathy, which has been linked to lower limb abnormalities that raise the risk for foot ulcers and amputations. Because amputations are a reason for pain and hospitalization in those with diabetes, it is of critical importance to gain insight about prevention of ulcer development in this population. Although the American Diabetes Association (ADA) now recommends that individuals with neuropathy can engage in moderate-intensity weight-bearing activity (WBA), they must wear appropriate footwear and inspect their feet daily. The physical forces and inflammatory processes from WBA may contribute to plantar characteristics that lead to ulcers. The purpose of this study was to compare neuropathic status and foot characteristics in Native Americans according to WBA classification. The t tests for unequal sample sizes found that exercisers had more difficulty sensing baseline temperature than nonexercisers, except at the right foot (all p values < .05). By dividing groups into no/low risk and high risk for ulcer, a majority showed no/low risk according to touch and vibration sense. Exercisers demonstrated higher surface skin temperature gradients at the first metatarsal head, a plantar site where wounds tend to form. The more consistently exercisers performed, the higher the plan-tar pressures were at the right second (r = .24, p = .02) and third metatarsal heads (r = .26, p = .01). Findings from this investigation do not refute current ADA recommendations and further intervention studies are needed that are longitudinal and measures WBA more accurately.

Bootstrapping to test for nonzero population correlation coefficients using univariate sampling.

This article proposes 2 new approaches to test a nonzero population correlation (rho): the hypothesis-imposed univariate sampling bootstrap (HI) and the observed-imposed univariate sampling bootstrap (OI). The authors simulated correlated populations with various combinations of normal and skewed variates. With alpha set=.05, N> or =10, and rho< or =0.4, empirical Type I error rates of the parametric r and the conventional bivariate sampling bootstrap reached .168 and .081, respectively, whereas the largest error rates of the HI and the OI were .079 and .062. On the basis of these results, the authors suggest that the OI is preferable in alpha control to parametric approaches if the researcher believes the population is nonnormal and wishes to test for nonzero rhos of moderate size.
