Impact of COVID-19 restrictions on the postpartum experience of women living in Eastern Canada during the early pandemic period: A cross-sectional study.

OBJECTIVES: To (1) compare changes in parenting self-efficacy, social support, postpartum anxiety, and postpartum depression in Canadian women before and during the early COVID-19 pandemic; (2) explore how women with a newborn felt during the pandemic; (3) explore ways that women coped with challenges faced. METHODS: A cross-sectional design was used. Prior to the pandemic, an online survey was conducted with women who an infant 6 months old or less in one of the three Eastern Canadian Maritime provinces. A similar survey was conducted during the pandemic in mid-2020. RESULTS: Pre-COVID, 561 women completed the survey, and 331 women during the pandemic. There were no significant differences in parenting self-efficacy, social support, postpartum anxiety, and depression between the cohorts. Difficulties that women reported because of COVID-19 restrictions included lack of support from family and friends, fear of COVID-19 exposure, feeling isolated and uncertain, negative impact on perinatal care experience, and hospital restrictions. Having support from partners and families, in-person/virtual support, as well as engaging in self-care and the low prevalence of COVID-19 during the summer of 2020 helped women cope. CLINICAL RELEVANCE: Women identified challenges and negative impacts due to the COVID-19 pandemic, although no differences in psychosocial outcomes were found. Consideration of public health policy during the postpartum period for the ongoing COVID-19 pandemic is needed. CONCLUSION: While there were no significant differences in psychosocial outcomes, there were still challenges and negative impacts that women identified.

The experience of remote recruitment for Essential Coaching for Every Mother during the coronavirus disease 2019 pandemic.

INTRODUCTION AND AIMS: Due to physical distancing recommendations because of the COVID-19 pandemic, recruitment approaches for perinatal research needed to shift from in-person to remote. The purpose of this study is to describe the recruitment and retention of women for an mHealth intervention study for Essential Coaching for Every Mother. METHODS: Three methods were used for recruitment: social media, posters in hospital, and media outreach. First time mothers were eligible for enrollment antenatally (37+ weeks) and postnatally (<3 weeks). Eligibility screening occurred remotely via text message. Outcomes were days to recruit 75 participants, eligibility vs. ineligibility rates, dropout and exclusion reasons, survey completion rates, perinatal timing of enrollment, and recruitment sources. RESULTS: Recruitment ran from 15 July to 19 September 2020 (67 days) with 200 potential participants screened and 88 enrolled. It took 50 days to enroll 75 participants. Women recruited antenatally were more likely to receive all intervention messages (68 vs. 19%) and miss fewer messages (6.4 vs. 13.8) than women enrolled postnatally. Participants heard about the study through family/friends (31%), news (20%), Facebook groups/ads (30%), posters (12%), or other (7%). CONCLUSION: Antenatal recruitment resulted in participants enrolling earlier and receiving more messages. Remote recruitment was a feasible way to recruit, with word of mouth and media outreach being most successful, followed by Facebook.

Neurodevelopmental outcomes of very preterm infants who received cord milking at birth: a randomized controlled trial.

Umbilical cord milking improves postnatal adaptation and short-term outcomes of very preterm infants compared to early cord clamping. Little is known about the impact of umbilical cord milking on long-term neurodevelopmental outcomes. The objective of this study is to compare the effects of intact umbilical cord milking (UCM) vs. early cord clamping (ECC) at birth on neurodevelopmental outcomes at 36 months' corrected age. Preterm infants < 31 weeks' gestation who were randomized at birth to receive three time milking of their attached cord or ECC (< 10 s) were evaluated at 36 months' corrected age. Neurodevelopmental outcomes were assessed by blinded examiners using Bayley Scales of Infant and Toddler Development (version III). Analysis was by intention to treat. Out of the 73 infants included in the original trial, 2 died and 65 (92%) infants were evaluated at 36 months' corrected age. Patient characteristics and short-term outcomes were similar in both study groups. There were no significant differences in the median cognitive, motor or language scores or in the rates of cerebral palsy, developmental impairment, deafness, or blindness between study groups. CONCLUSION: Neurodevelopmental outcomes at 36 months' corrected age of very preterm infants who received UCM were not shown to be significantly different from those who received ECC at birth. TRIAL REGISTRATION: ClinicalTrials.gov: NCT01487187 What is Known: • Compared to early cord clamping, umbilical cord milking improves postnatal adaptation and short-term outcomes of very preterm infants compared to early cord clamping. • Little is known about the impact of umbilical cord milking on neurodevelopmental outcomes. WHAT IS NEW: • Neurodevelopmental outcomes at 3 years of age were not significantly different in very preterm infants who received cord milking vs. those who received early cord clamping at birth.

Effectiveness of the "Essential Coaching for Every Mother" postpartum text message program on maternal psychosocial outcomes: A randomized controlled trial.

Objective: To determine the effectiveness of the Essential Coaching for Every Mother program on maternal self-efficacy, perceived social support, postpartum anxiety, and postpartum depression at six-weeks postpartum. Methods: Participants from Nova Scotia were randomized, stratified by parity, to receive either the Essential Coaching for Every Mother postpartum text-message program or usual care, from birth to six-weeks postpartum. Participants completed surveys at enrollment (after birth) and at 6 weeks. Differences between groups were analyzed using analysis of covariance, considering parity and group allocation. Results: Of the 171 participants recruited (53% primiparous), 150 completed the baseline survey (intervention n = 78, control n = 72). At baseline, newborns were on average 4.4 days old (SD: 3.9) and mothers 31.4 years old (SD: 4.5). Controlling for maternal age, primiparous women in the intervention group had a greater increase in maternal self-efficacy than primiparous women in the control group (mean difference [MD] = 4.84 (standard error [SE] = 0.75) vs. MD = 2.13 (SE = 0.81), p = 0.034). Women allocated to the intervention group had a greater reduction in postpartum anxiety symptoms than women in the control group for both multiparous and primiparous women (MD = -3.91 (SE = 1.82) vs. 2.81 (SE = 1.86), p = 0.011). There was no significant change in postpartum depression scores or perceived social support for either group. Discussion: This study presents the results of the first Canadian postpartum text message program, which found improved psychosocial outcomes for postpartum women. Given the potential to reach numerous women at a low cost across geographical locations, the scalability of this intervention can improve maternal self-efficacy and reduce postpartum anxiety.

Participants' Perceptions of Essential Coaching for Every Mother-a Canadian Text Message-Based Postpartum Program: Process Evaluation of a Randomized Controlled Trial.

BACKGROUND: "Essential Coaching for Every Mother" is a Canadian text message-based program that sends daily messages to mothers for 6 weeks after they give birth. There is a need to explore the program's effectiveness in terms of the participants' experience to guide refinement and modification. OBJECTIVE: This study aimed to describe the process evaluation of the Essential Coaching for Every Mother randomized controlled trial through an evaluation of the research implementation extent and quality. METHODS: Participants were recruited from Nova Scotia, Canada, between January 5 and August 1, 2021. Enrolled participants were randomized into the intervention or control group. Participants randomized to the intervention group received standard care along with the Essential Coaching for Every Mother program's text messages related to newborn and maternal care for the first 6 weeks after giving birth, while the control group received standard care. Usage data were collected from the SMS text message program used, and participants completed web-based questionnaires at 6 weeks after birth. Quantitative data and qualitative responses to open-ended questions were used to triangulate findings. Quantitative data were summarized using means, SDs, and percentages, as appropriate, while qualitative data were analyzed using thematic analysis. RESULTS: Of the 295 unique initial contacts, 150 mothers were eligible and completed the baseline survey to be enrolled in the study (intervention, n=78; control, n=72). Of those randomized into the intervention group, 75 (96%) completed the 6-week follow-up survey to provide feedback on the program. In total, 48 (62%) intervention participants received all messages as designed in the Essential Coaching for Every Mother program, with participants who enrolled late missing on average 4.7 (range 1-12) messages. Intervention participants reported an 89% satisfaction rate with the program, and 100% of participants would recommend the program to other new mothers. Participants liked how the program made them feel, the format, appropriate timing of messages, and content while disliking the frequency of messages and gaps in content. Participants also provided suggestions for future improvement. CONCLUSIONS: Our process evaluation has provided a comprehensive understanding of interest in the program as well as identified preference for program components. The findings of this study will be used to update future iterations of the Essential Coaching for Every Mother program.

Implementing Essential Coaching for Every Mother during the COVID-19 pandemic: A pre-post intervention study.

OBJECTIVES: The primary objective of this project was to evaluate the preliminary impact of Essential Coaching for Every Mother on maternal self-efficacy, social support, postpartum anxiety, and postpartum depression. The secondary objective was to explore the acceptability of the Essential Coaching for Every Mother program provided during the COVID-19 pandemic. METHODS: A prospective pre-post study was conducted with first-time mothers in Nova Scotia, Canada, between July 15 and September 19, 2020. Participants completed a self-report survey at enrollment (after birth) and 6 weeks postpartum. Various standardized measures were used, and qualitative feedback on the program was also collected. Paired t tests were carried out to determine changes from baseline to follow-up on psychosocial outcomes, and qualitative feedback was analyzed through thematic analysis. RESULTS: A total of 88 women enrolled. Maternal self-efficacy increased between baseline (B) and follow-up (F) (B: 33.33; F: 37.11, P = 0.000), whereas anxiety (STAI) declined (B: 38.49; F: 34.79, P = 0.004). In terms of acceptability, 89% of participants felt that the number of messages was just right, 84.5% felt the messages contained all the information they needed relative to caring for a newborn, and 98.8% indicated they would recommend this program to other new mothers. CONCLUSIONS: Essential Coaching for Every Mother may play a role in increasing maternal self-efficacy and decreasing anxiety, although future work with a control group is needed to delineate the true effects of the program. Overall, mothers were satisfied with the Essential Coaching for Every Mother program and would recommend it for other mothers, during the COVID-19 pandemic and beyond.

Canadian Women's Experience of Postnatal Care: A Mixed Method Study.

BACKGROUND: The postnatal period remains unstandardized in terms of care and postnatal visits with a dearth of information on the experience from Canadian women. PURPOSE: To explore (1) with whom and how often women receive postnatal follow-up visits and (2) the postnatal care experiences of Canadian mothers. METHODS: Using a cross-sectional design, women who had given birth within the past 6 months were recruited to complete an online survey. Frequencies were computed for quantitative outcomes and thematic analysis was used for qualitative responses. RESULTS: A total of 561 mothers completed the survey. Women saw on average 1.9 different postnatal healthcare providers, primarily family doctors (72.4%). 3.2% had no postnatal visits and 37.6% had 4 or more within 6 weeks. 76.1% women were satisfied with their postnatal care. Women's satisfactory care in the postnatal period was associated with in-person and at home follow-ups, receiving support, and receiving timely, appropriate care for self and newborn. Unsatisfactory care was associated with challenges accessing care, experiencing gaps in follow-up visits, and having unsatisfactory assessment for their own recovery. CONCLUSION: There is considerable variation in the timing and frequency of postnatal visits. While many women are experiencing satisfactory care, women are still reporting dissatisfaction and are facing challenges.

Influence of parity and infant age on maternal self-efficacy, social support, postpartum anxiety, and postpartum depression in the first six months in the Maritime Provinces, Canada.

BACKGROUND: After giving birth, women experience significant changes related to maternal self-efficacy and social support and are at risk of experiencing postpartum anxiety and depression. PROBLEM: No studies have focused on the relationship between parity and infant age and their impact on psychosocial outcomes, particularly in a Canadian context. AIM: To explore the relationship between parity and infant age on perceived maternal self-efficacy, social support, postpartum anxiety, and postpartum depression. METHODS: Women from three Canadian provinces within the first 6 months postpartum completed standardized online questionnaires. Multivariate analysis of covariance was used to examine the primary aim. FINDINGS: A total of 561 women (56.5% primiparous, 55.1% infant 0-3 months) participated. There were significant main effects for both parity (P < .001) and age of infant (P < .001), but no significant interaction (P = .463). Primiparous women had lower maternal self-efficacy (P = .004) and higher postpartum anxiety (P = .000) than multiparous women. Women with younger infants had more perceived social support (P = .002). Women with older infants had higher levels of postpartum anxiety (P = .003) and depression (P = .000). DISCUSSION: The transition that women experience, independent of parity, within the first six months is dynamic with women of older infants experiencing more postpartum mental health concerns and less perceived social support. Our findings emphasize that postnatal support should extend beyond the typical six-week follow-up period. CONCLUSIONS: Additional studies are warranted to determine ways to provide ongoing support throughout the first six months and beyond to improve maternal well-being and address postpartum needs.

Effectiveness of a Postpartum Text Message Program (Essential Coaching for Every Mother) on Maternal Psychosocial Outcomes: Protocol for a Randomized Controlled Trial.

BACKGROUND: Women experience changes both physically and psychologically during their transition to motherhood. The postnatal period is a critical time for women to develop maternal self-efficacy. Mobile health interventions may offer a way to reach women during this critical period to offer support and information. Essential Coaching for Every Mother is a text message program that seeks to educate and support women during the first 6 weeks postpartum. OBJECTIVE: The primary effectiveness objective is to compare the effectiveness of the Essential Coaching for Every Mother program on maternal psychosocial outcomes (self-efficacy, social support, postpartum depression, and postpartum anxiety) immediately after the intervention and 6 months postpartum, collectively as well as stratified by parity. The primary implementation objective is to evaluate the implementation extent and quality of the Essential Coaching for Every Mother program. METHODS: This will be a hybrid type 1 effectiveness-implementation randomized controlled trial. A total of 140 mothers-to-be or new mothers from Nova Scotia will be recruited and randomized to the intervention or control arm, stratified by parity. The intervention arm will receive the Essential Coaching for Every Mother program, which consists of 53 messages sent twice a day for the first 2 weeks and daily for weeks 3 through 6. The control group will receive usual care. Messages are personalized based on the infant's age and the woman's self-selected preference for breastfeeding or formula feeding and tailored with the infant's name and gender. Women can enroll in the program if they are ≥37 weeks pregnant or within 10 days postpartum, with the first message designed to be sent on the second evening after birth. The actual number of messages received will vary based on the timing of enrollment and the infant's date of birth. Participants will complete questionnaires assessing self-efficacy, social support, and postpartum depression and anxiety at baseline (enrollment after birth) and 6 weeks (postintervention) and 6 months postpartum. Implementation data will be collected throughout the trial, and evaluation feedback will be collected at 6 weeks from women who received the intervention. RESULTS: Recruitment for this study started on January 5, 2021, and is currently ongoing, with an anticipated date of recruitment completion of January 2022. CONCLUSIONS: This study will assess the effectiveness of a postpartum text message program to improve maternal self-efficacy and social support while decreasing postpartum depression and anxiety. It will also shed light on the implementation effectiveness of the program. TRIAL REGISTRATION: ClinicalTrials.gov NCT04730570; https://clinicaltrials.gov/ct2/show/NCT04730570.

Automated control of fraction of inspired oxygen: is it time for widespread adoption?

PURPOSE OF REVIEW: Over the past two decades, numerous algorithms for automated control of the fraction of inspired oxygen (FiO2) have been developed and incorporated into contemporary neonatal ventilators and high-flow devices in an attempt to optimize supplemental oxygen therapy in preterm infants. This review explores whether current evidence is sufficient to recommend widespread adoption of automated oxygen control in neonatal care. RECENT FINDINGS: To date, 15 studies have compared automated versus manual control of FiO2 in preterm infants on respiratory support. This includes four new randomized cross-over trials published in the last 2 years. Available evidence consistently demonstrates a significant improvement in time spent within the target saturation range with automated FiO2 control. There are fewer episodes of severe hypoxemia and fewer manual FiO2 adjustments with automated oxygen control. Nursing workload may be reduced. However, no currently completed studies report on clinical outcomes, such as chronic lung disease or retinopathy of prematurity. SUMMARY: Automated oxygen control appears to be a reasonable option for FiO2 titration in preterm infants on respiratory support, if resources are available, and might substantially reduce nursing workload. Further randomized clinical trials to explore its effects on clinical outcomes are required.

SAR Matrices Enable Discovery of Mixed Efficacy µ-Opioid Receptor Agonist Peptidomimetics with Simplified Structures through an Aromatic-Amine Pharmacophore.

We previously described the development of potent µ-opioid receptor (MOR)-agonist/δ-opioid receptor (DOR)-antagonist peptidomimetic ligands as an approach toward effective analgesics with reduced side effects. In this series, a tetrahydroquinoline (THQ) or substituted phenyl is employed to link two key pharmacophore elements, a dimethyltyrosine amino acid and typically an aromatic pendant. Using new and previously reported analogues, we constructed a structure-activity relationship (SAR) matrix that probes the utility of previously reported amine pendants. This matrix reveals that the MOR-agonist/DOR-antagonist properties of these ligands do not change when a tetrahydroisoquinoline (THIQ) pendant is used, despite removal of substituents on the core phenyl ring. Based on this observation, we retained the THIQ pendant and replaced the phenyl core with simpler aliphatic chain structures. These simpler analogues proved to be potent MOR-agonists with high variability in their effects at the DOR and the κ-opioid receptor (KOR). These data show that the amine of the THIQ pendant may be a novel pharmacophore element that favors high MOR-efficacy, whereas the aromatic ring of the THIQ pendant may produce high MOR-potency. Combined, the two pharmacophores within the THIQ pendant may be a structurally efficient means of converting opioid peptides and peptidomimetics into potent and efficacious MOR-agonists.

Design, development and usability testing of Essential Coaching for Every Mother: A postnatal text message educational intervention.

BACKGROUND: The transition to motherhood is an exciting yet challenging period that requires physical, emotional, and social adjustment. During the postpartum period, mothers require support and information to ensure a smooth transition and adjustment to motherhood. One innovative strategy to provide mothers with this information is mobile health (mHealth), and specifically, text messaging. OBJECTIVE: To describe the design, development and usability testing of a postnatal text message intervention called Essential Coaching for Every Mother. METHODS: First time mothers (n=11) and postpartum healthcare providers (n=18) were involved in iterative interviewing in Halifax, Canada. Adaption of content occurred through three rounds of user testing using semi-structured interviews. The Information Assessment Method (IAM) Parents survey was also completed by mothers. RESULTS: Three cycles of iterative testing were conducted with eight participants (3 mothers, 5 healthcare providers), thirteen participants (8 mothers, 5 healthcare providers) and 8 participants (8 healthcare providers), respectively. Messages evolved from risk-focused to prevention and education focused. Mothers felt the messages addressed their needs and healthcare providers ensured the content was consistent with the messaging currently provided to postpartum mothers. CONCLUSION: Essential Coaching for Every Mother is the first postnatal educational text message intervention developed for mothers in Halifax, Canada. We sought to involve first time mothers (end-users) and postpartum healthcare providers (experts) in the development and usability evaluation to ensure the intervention adequately met needs and was consistent with current practices related to postpartum education.

The effect of umbilical cord milking on cerebral blood flow in very preterm infants: a randomized controlled study.

OBJECTIVE: To compare the effect of umbilical cord milking (UCM) vs. early cord clamping (ECC) on cerebral blood flow (CBF). METHOD: Preterm infants <31 weeks' gestation were randomized to receive UCM or ECC at birth. Blood flow velocities and resistive & pulsatility indices of middle and anterior cerebral arteries were measured at 4-6 and 10-12 h after birth as an estimate of CBF. RESULTS: Randomization allocated 37 infants to UCM and 36 to ECC. Maternal and antenatal variables were similar. There were no significant differences between groups in middle or anterior CBF velocities and resistive indices at either study time point. CBF variables were not correlated with mean blood pressure, systemic blood flow, or intraventricular hemorrhage. CONCLUSIONS: In very preterm infants, UCM compared with ECC was not shown to change CBF indices during the first 12 h of age or correlate with other hemodynamic measures or with intraventricular hemorrhage. TRIAL REGISTRATION: ClinicalTrials.gov: NCT01487187.

Beyond Newborn Resuscitation: Essential Care for Every Baby and Small Babies.

Helping Babies Breathe (HBB) addresses a major cause of newborn mortality by teaching basic steps of neonatal resuscitation and improving survival rates of infants affected by intrapartum-related events or asphyxia. Addressing the additional top causes of mortality (infection and prematurity) requires more comprehensive education, including content on thermal and nutritional support, breastfeeding, and alternative feeding strategies, as well as recognition and treatment of infection. Essential Care for Every Baby (ECEB) and Essential Care for Small Babies (ECSB) use educational principles developed with HBB as a model for teaching basic newborn care. These programs complement the content provided with HBB, further integrate counseling of families, and advance the agenda of providing quality care to all infants at birth. ECEB and ECSB have further demonstrated that engagement of individuals through active participation in their education empowers providers at all levels. With added experience teaching and implementing ECEB and ECSB, the next generation of newborn educational programs will likely incorporate bedside teaching and clinical exposure, multimedia platforms for demonstrating clinical content, and added efforts toward quality improvement. Through ECEB and ECSB, the attention brought to the newborn health agenda with HBB has only grown. Although current global health issues pose new challenges in implementing this agenda, these programs together provide a critical framework to both educate and advocate for optimal care of every newborn.

Development and Impact of Helping Babies Breathe Educational Methodology.

The educational pedagogy surrounding Helping Babies Breathe (HBB) has been transformative in going beyond a curriculum focused only on basic neonatal resuscitation; indeed, it created the framework for an educational program that has served as a model for replication for other impactful programs, such as the Helping Mothers Survive and other Helping Babies Survive curricula. The tenets of HBB include incorporation of innovative learning strategies such as small group discussion, skills-based learning, simulation and debriefing, and peer-to-peer learning, all of which begin the hard work of changing behaviors that may eventually affect health care systems. Allowing for adaptation for local resources and culture, HBB has catalyzed innovation in the development of simplified, pictorial educational materials, in addition to low-tech yet realistic simulators and adjunct devices that have played an important role in empowering health care professionals in their care of newborns, thereby improving outcomes. In this review, we describe the development of HBB as an educational program, the importance of field testing and input from multiple stakeholders including frontline workers, the strategies behind the components of educational materials, and the impact of its pedagogy on learning.

An evaluation of Acute Care of at-Risk Newborns (ACoRN), a Canadian education program, in Chinese neonatal nurseries.

BACKGROUND: The Acute Care of at-Risk Newborns (ACoRN) program was developed in Canada to train health care providers in the identification and management of newborns who are at-risk and/or become unwell after birth. The ACoRN process follows a stepwise framework that enables evaluation, decision, and action irrespective of caregiver experience. This study examined the hypothesis that the ACoRN educational program improved clinical practices and outcomes in China. METHODS: In a before-and-after study, ACoRN training was provided to physicians, neonatal nurses, and administrators in 16 county hospitals in Zhejiang, PRC. Demographic and clinical data were collected on babies admitted to neonatal units before (May 1, 2008 to March 31, 2009) and after (June 1, 2010 to April 30, 2012) training. RESULTS: A total of 4,310 babies (1,865 pre- and 2,445 post-training) from 14 sites were included. There were more in-hospital births (97.8% versus 95.6%, P<0.01) in the post-training epoch, fewer babies needing resuscitation (12.7% versus 16.0%, P=0.02), and more babies finishing their care in hospital (67.4% versus 53.1%, P<0.0001). After training, significantly more babies were evaluated as having respiratory distress at admission (14.2% versus 9.4%, P<0.0001); more babies had saturation, glucose and temperature measured on admission and at discharge; and more babies received intravenous fluids (86.3% versus 72.8%, P<0.0001). No significant improvements were noted in mortality (0.49% [post] versus 0.8% [pre], P=0.19 and adjusted odds ratio 0.54, 95% confidence interval: 0.23 to 1.29). CONCLUSIONS: ACoRN training significantly increased patient evaluations and changed clinical practices. However, we were unable to ascertain improvement in morbidity or mortality.

Centrally administered CYP2D inhibitors increase oral tramadol analgesia in rats.

Cytochrome P450 2D (CYP2D) mediates the activation and inactivation of several classes of psychoactive drugs, including opioids, which can alter drug response. Tramadol is a synthetic opioid with analgesic activity of its own as well as being metabolically activated by CYP2D to O-desmethyltramadol (ODMST) an opioid receptor agonist. We investigated the impact of brain CYP2D metabolism on central tramadol and ODSMT levels, and resulting analgesic response after oral tramadol administration in rats. CYP2D inhibitors propranolol and propafenone were administered intracerebroventricularly prior to oral tramadol administration and analgesia was measured by tail-flick latency. Drug levels of tramadol and its metabolites, ODSMT and N-desmethyltramadol, were assessed in plasma and in brain by microdialysis using LC-ESI-MS/MS. Inhibiting brain CYP2D with propafenone pretreatment increased analgesia after oral tramadol administration (ANOVA p = 0.02), resulting in a 1.5-fold increase in area under the analgesia-time curve (AUC0-60, p < 0.01). This effect was associated with changes in the brain levels of tramadol and its metabolites consistent with brain CYP2D inhibition. In conclusion, under oral tramadol dosing pretreatment with a central administration of the CYP2D inhibitor propafenone increased analgesia (without altering plasma drug or metabolite levels), indicating that tramadol itself (and activity of CYP2D within the brain) contributed to analgesia.

First-step validation of a text message-based application for newborn clinical management among pediatricians.

BACKGROUND: Neonatal mortality is high in developing countries. Lack of adequate training and insufficient management skills for sick newborn care contribute to these deaths. We developed a phone application dubbed Protecting Infants Remotely by Short Message Service (PRISMS). The PRISMS application uses routine clinical assessments with algorithms to provide newborn clinical management suggestions. We measured the feasibility, acceptability and efficacy of PRISMS by comparing its clinical case management suggestions with those of experienced pediatricians as the gold standard. METHODS: Twelve different newborn case scenarios developed by pediatrics residents, based on real cases they had seen, were managed by pediatricians and PRISMS®. Each pediatrician was randomly assigned six of twelve cases. Pediatricians developed clinical case management plans for all assigned cases and then obtained PRISMS suggested clinical case managements. We calculated percent agreement and kappa (k) statistics to test the null hypothesis that pediatrician and PRISMS management plans were independent. RESULTS: We found high level of agreement between pediatricians and PRISMS for components of newborn care including: 10% dextrose (Agreement = 73.8%), normal saline (Agreement = 73.8%), anticonvulsants (Agreement = 100%), blood transfusion (Agreement =81%), phototherapy (Agreement = 90.5%), and supplemental oxygen (agreement = 69.1%). However, we found poor agreement with potential investigations such as complete blood count, blood culture and lumbar puncture. PRISMS had a user satisfaction score of 3.8 out of 5 (range 1 = strongly disagree, 5 = strongly agree) and an average PRISMS user experience score of 4.1 out of 5 (range 1 = very bad, 5 = very good). CONCLUSION: Management plans for newborn care from PRISMS showed good agreement with management plans from experienced Pediatricians. We acknowledge that the level of agreement was low in some aspects of newborn care.

Effect of Fentanyl Boluses on Cerebral Oxygenation and Hemodynamics in Preterm Infants: A Prospective Observational Study.

BACKGROUND: Fentanyl is a commonly used off-label medication for pain control and sedation in preterm infants. Yet, the effect of fentanyl on cerebral hemodynamics in preterm neonates remains unexplored. OBJECTIVE: To evaluate the effect of a bolus dose of fentanyl on the regional cerebral oxygen saturation (RcSO2), cerebral fractional tissue oxygen extraction (cFTOE) and left ventricular output (LVO) as compared with pre-administration baseline in preterm infants. METHODS: This was a prospective observational study conducted in a level III Canadian NICU from September 2017 to February 2019. Preterm infants born <37 weeks of gestation and scheduled to receive a fentanyl bolus (1-2 µg/kg/dose) were eligible. Infants with major congenital anomalies, medically unstable and those who had received fentanyl in the previous 48 h were excluded. OUTCOMES: The primary outcome was the difference between RcSO2 measured 5 min prior to and RcSO2 measured at defined time points after administration of fentanyl. RESULTS: Twenty-eight infants were enrolled during the study period (median gestational age 28 weeks; interquartile range [IQR] 25-29 weeks; median birth weight 1,035 g [IQR 830-1,292 g]; median age 4 days [IQR 3-7 days]). Mean (±standard deviation) baseline RcSO2 was 73.6% (±11.8), cFTOE was 21.9 (±11.2) and LVO was 380 (±147) mL/kg/min prior to fentanyl infusion. One-way ANOVA showed no statistically significant difference between baseline and any of the post-fentanyl cerebral oxygenation, tissue oxygen extraction or cardiac output measures (p > 0.05). CONCLUSION: Administration of fentanyl bolus for procedural pain and sedation was not shown to significantly affect cerebral oxygenation, cerebral tissue oxygen extraction or cardiac output in stable preterm infants.

Epidemiology of thrombosis in Canadian neonatal intensive care units.

OBJECTIVE: To assess the rate, location, risk factors, management, and outcomes of neonatal thrombosis (NT). DESIGN: A retrospective study investigating infants admitted to NICUs in Canadian Neonatal Network between January 2014 and December 2016 and diagnosed with NT. Each infant with NT was matched with an infant without NT. RESULTS: Of 39,971 infants, 587 (1.5%) were diagnosed with NT: 440 (75%) venous, 112 (19%) arterial, 29 (5%) both. NT rate was 1.4% in full-term and 1.7% in preterm infants. Venous thrombi occurred most commonly in the portal vein and arterial thrombi in the cerebral artery. Conservative management and low molecular weight heparin were the most common treatment modalities. Hospital stay was longer (p < 0.001) in the NT patients, but mortality was similar. CONCLUSIONS: NT was diagnosed in ~15/1000 NICU admissions and most commonly in the portal vein and cerebral arteries. Management varied based on the type and location of thrombi. Large multicenter trials are needed to address the best management strategies.
