[PMID: 37479886 DOI: 10.1038/s41372-023-01733-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/24/2023] [Revised: 07/04/2023] [Accepted: 07/11/2023] [Indexed: 07/23/2023]
Abstract
OBJECTIVE To determine the association of maternal pre-pregnancy body mass index (BMI) and neurodevelopmental impairment (NDI) at 18-24 months corrected age (CA) in infants born < 29 weeks gestation. STUDY DESIGN Infants born between 2005 and 2015 at < 29 weeks gestation were included. BMI was categorized into BMI1 [18.5-24.9 kg/m2], BMI2 [25-29.9 kg/m2], BMI3 [ ≥ 30 kg/m2]. Primary outcome was death or NDI (Bayley-III scores < 85, cerebral palsy, hearing or visual impairment). Univariate and multivariate analysis were used. RESULTS There were 315 infants in BMI1, 235 in BMI2, and 147 in BMI3 groups. Adjusted odds ratio (aOR) of death or NDI in BMI2 vs. BMI1 and BMI3 vs BMI1 groups were 1.33 (95% CI 0.86-2.06) and 0.76 (95% CI 0.47-1.22). Adjusted odds ratio of Bayley-III language composite < 85 was 2.06 (95% CI 1.28-3.32). CONCLUSION Pre-pregnancy BMI was not associated with death or NDI in extremely preterm infants. Infants born to overweight mothers had higher odds of low language scores.

Abstract
PURPOSE/OBJECTIVE(S) Radiation (RT)-induced lymphopenia (RIL) occurs in up to 75% of patients undergoing RT and is associated with worse tumor control and survival across a spectrum of solid tumors. Patients undergoing hypofractionated RT are at lower risk of RIL compared with patients treated with more prolonged RT courses. However, it is unknown whether immune repertoire diversity is similarly affected by fractionation scheme in patients undergoing RT. This prospective study analyzed RT-induced changes in immune repertoire diversity in patients treated with conventionally (CFRT) vs hypofractionated RT (HFRT). MATERIALS/METHODS RNA-based T and B cell receptor sequencing was performed on peripheral lymphocytes collected prospectively before RT and within 4 weeks of the last RT fraction from 23 patients (18 men, 5 women, median age 67 y) with primary solid tumors undergoing CFRT (≤3 Gy/day x ≥10 days, n = 13) or HFRT (≥5 Gy/day x ≤5 days, n = 10). Absolute lymphocyte counts (ALC; cells/μL) were obtained from clinical laboratory data. The number of unique CDR3 receptors (uCDR3) and Shannon entropy were used to monitor changes in T (TCR Vβ) and B (BCR IgH) receptor diversity. RESULTS ALC decreased after RT in 90% (20/22) of patients (mean pre-RT ALC 1830 vs 1040 post-RT, p <0.001). Mean % ALC loss was greater in CFRT vs HFRT patients (44.3 vs. 35.2%). After RT, entropy in IgH and Vβ decreased in 18/23 (78%) and 17/23 (74%) patients, respectively; uCDR3 in IgH and Vβ decreased in 14/23 (61%) and 15/23 (65%). Among patients with concordant decreases in ALC and uCDR3, a moderate correlation between magnitude of ALC loss and uCDR3 levels in the T-cell receptor Vβ was observed (r = 0.64, p = 0.02). For both receptor species studied (IgH and Vβ), HFRT patients were more likely to have an increase in either entropy or uCDR3 in the face of decreased ALC (36 vs 15%, X2 p = 0.03). Furthermore, while decreases in entropy were observed among the CFRT patients for both IgH (median entropy 10.4 vs 9.4, p = 0.06) and Vβ (9.7 vs 8.1, p = 0.02), entropy did not significantly change following RT in the HFRT patients (IgH 10.6 vs 10.4, p = 0.74 and Vβ 10.9 vs 10.8, p = 0.24). CONCLUSION RT-induced changes in immune repertoire diversity are variably reflected in the peripheral ALC. Both HFRT and CFRT depleted circulating lymphocytes, but patients undergoing HFRT were more likely to experience increases in T and B cell diversity metrics despite lymphopenia. It is therefore possible that relative sparing of repertoire diversity among patients undergoing HFRT could increase the likelihood of tumor antigen recognition by peripheral blood lymphocytes. As immune repertoire diversity is associated with the likelihood of response to immunotherapy, these findings also have implications for RT-immunotherapy combinations. Further study is required to understand the relationship between RT exposure to circulating lymphocyte populations and immune repertoire diversity.

Abstract
OBJECTIVE To determine neurodevelopmental outcomes of preterm infants born at < 29 weeks gestational age (GA) with bronchopulmonary dysplasia and pulmonary hypertension (BPD-PH) at 18 to 24 months corrected age (CA). METHODS In this retrospective cohort study, preterm infants born at < 29 weeks GA between January 2016 and December 2019, admitted to level 3 Neonatal Intensive Care Units, who developed BPD and were evaluated at 18-24 months CA in the neonatal follow-up clinics were included. We compared demographic characteristics and neurodevelopmental- outcomes between the two groups: Group I: BPD with PH and Group II: BPD without PH, using univariate and multivariate regression models. The primary outcome was a composite of death or neurodevelopmental impairment (NDI). NDI was defined as any Bayley-III score < 85 on one or more of the cognitive, motor, or language composite scores. RESULTS Of 366 eligible infants, 116 (Group I [BPD-PH] =7, Group II [BPD with no PH] =109) were lost to follow-up. Of the remaining 250 infants, 51 in Group I and 199 in Group II were followed at 18-24 months CA. Group I and Group II had median (IQR) birth weights of 705 g (325) and 815g (317) [p=0.003] and median gestational ages (IQR) were 25 weeks (2) and 26 weeks (2) [p=0.015], respectively. Infants in the BPD-PH group (Group I) were more likely to have mortality or NDI (adjusted Odds Ratio [aOR] 3.82; bootstrap 95% CI; 1.44-40.87). CONCLUSION BPD-PH in infants born at < 29 weeks GA is associated with increased odds of the composite outcome of death or NDI at 18-24 months CA.

Abstract
Background Resorption of primary teeth and eruption of permanent teeth involves a complex series of changes. The cellular and histological changes occurring during the process of resorption vary stagewise. The knowledge of the changes occurring in the pulp of deciduous teeth would provide information about the resorptive process. Aim To evaluate the histologic changes of the pulp of deciduous teeth related to different stages of physiologic root resorption. Study setting and design To establish the cause and effect relationship, a contrived histologic study design was planned. Materials and methods A total of 60 extracted deciduous incisors, canines, and molars were included in the study. The remaining root length (RRL) was determined based on the standardized photographs. The teeth were then grouped into three based on the percentage of RRL. The teeth were subjected to decalcification with 5% nitric acid, following which histological processing was performed. Statistical analysis The present study being a qualitative study design, descriptively explains the histologic findings, and no statistical tests have been applied. Results During the initial stages of resorption, there were no histological alterations noted in the pulp, particularly in the cervical 3rd, with the cellular structure relatively maintained. As the resorption progresses, reversal lines were evident, indicating a process of repair occurring simultaneously during the process of resorption. With further advancement, the repair is overtaken by the resorption indicated by the presence of resorptive cells. Neovascularization and an increase in immune cells are also evident in advanced stages. Conclusion The pulp exhibits progressive changes as the resorption continues from stage I to stage III. The changes vary from a smaller number of immune cells and odontoclasts in stage I to increasing number of the same as resorption progresses. How to cite this article Murthy P, Bhojraj N, Hegde U.

The Utility of Simulation-Based Training in Teaching Frontline Providers Modified Sarnat Encephalopathy Examination: A Randomized Controlled Pilot Trial. Pediatr Neurol 2023; 139:70-75. [PMID: 36543025 DOI: 10.1016/j.pediatrneurol.2022.11.009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/23/2022] [Revised: 08/24/2022] [Accepted: 11/20/2022] [Indexed: 11/26/2022]
Abstract
BACKGROUND Limited training in targeted neurological examination makes it challenging for frontline providers to identify newborns with perinatal asphyxia eligible for therapeutic hypothermia. This training is important in the era of telemedicine, where the experts can remotely guide further care of these newborns. METHODS This randomized controlled pilot study was conducted in a South Indian tertiary hospital. Neonatal nurses, who had no previous hands-on experience in MSEE, were trained in modified Sarnat staging by a didactic teaching session using online teaching module. The nurses were then randomized into two groups for hands-on demonstration by the same trainer (low-fidelity mannequin versus a healthy term newly born infant). After the training period, MSEEs of a normal newborn were performed independently by nurses and were video recorded and assessed by three blinded neonatologists with expertise in neonatal neurology. A follow-up examination was performed by the same nurses after three months to assess skill retention. RESULTS The 10 global ratings of the components of the MSEE were comparable among both groups in both initial and follow-up assessments. The overall diagnostic value was comparable between the simulation and traditional groups (93.75%, 94.11%, respectively). Follow-up examination after three months showed better skill retention in the simulation group (84%) compared with the traditional group (66.7%). CONCLUSIONS Online-based and low-fidelity mannequin training was equally effective as the traditional method of teaching MSEE in term neonates.

Advanced neonatal procedural skills: a simulation-based workshop: impact and skill decay. BMC MEDICAL EDUCATION 2023; 23:26. [PMID: 36639668 PMCID: PMC9837896 DOI: 10.1186/s12909-023-04000-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 08/08/2022] [Accepted: 01/04/2023] [Indexed: 06/17/2023]
Abstract
BACKGROUND Trainees aiming to specialize in Neonatal Perinatal Medicine (NPM), must be competent in a wide range of procedural skills as per the Royal College of Canada. While common neonatal procedures are frequent in daily clinical practice with opportunity to acquire competence, there are substantial gaps in the acquisition of advanced neonatal procedural skills. With the advent of competency by design into NPM training, simulation offers a unique opportunity to acquire, practice and teach potentially life-saving procedural skills. Little is known on the effect of simulation training on different areas of competence, and on skill decay. METHODS We designed a unique simulation-based 4-h workshop covering 6 advanced procedures chosen because of their rarity yet life-saving effect: chest tube insertion, defibrillation, exchange transfusion, intra-osseus (IO) access, ultrasound-guided paracentesis and pericardiocentesis. Direct observation of procedural skills (DOPS), self-perceived competence, comfort level and cognitive knowledge were measured before (1), directly after (2), for the same participants after 9-12 months (skill decay, 3), and directly after a second workshop (4) in a group of NPM and senior general pediatric volunteers. RESULTS The DOPS for all six procedures combined for 23 participants increased from 3.83 to 4.59. Steepest DOPS increase pre versus post first workshop were seen for Defibrillation and chest tube insertion. Skill decay was evident for all procedures with largest decrease for Exchange Transfusion, followed by Pericardiocentesis, Defibrillation and Chest Tube. Self-perceived competence, comfort and cognitive knowledge increased for all six procedures over the four time points. Exchange Transfusion stood out without DOPS increase, largest skill decay and minimal impact on self-assessed competence and comfort. All skills were judged as better by the preceptor, compared to self-assessments. CONCLUSIONS The simulation-based intervention advanced procedural skills day increased preceptor-assessed directly observed procedural skills for all skills examined, except exchange transfusion. Skill decay affected these skills after 9-12 months. Chest tube insertions and Defibrillations may benefit from reminder sessions, Pericardiocentesis may suffice by teaching once. Trainees' observed skills were better than their own assessment. The effect of a booster session was less than the first intervention, but the final scores were higher than pre-intervention. TRIAL REGISTRATION Not applicable, not a health care intervention.

Abstract
Neonatal hypoxic-ischemic encephalopathy is a clinical phenomenon that often results from perinatal asphyxia. To mitigate secondary neurologic injury, prompt initial assessment and diagnosis is needed to identify patients eligible for therapeutic hypothermia. However, occasionally neonates present with a clinical picture of hypoxic-ischemic encephalopathy without significant risk factors for perinatal asphyxia. We hypothesized that in patients with genetic abnormalities, the clinical manifestation of those abnormalities may overlap with hypoxic-ischemic encephalopathy criteria, potentially contributing to a causal misattribution. We reviewed 210 charts of infants meeting local protocol criteria for moderate to severe hypoxic-ischemic encephalopathy in neonatal intensive care units in Calgary, Alberta. All patients that met criteria for therapeutic hypothermia were eligible for the study. Data were collected surrounding pregnancy and birth histories, as well as any available genetic or metabolic testing including microarray, gene panels, whole-exome sequencing, and newborn metabolic screens. Twenty-eight patients had genetic testing such as microarray, whole-exome sequencing, or a gene panel, because of clinical suspicion. Ten of 28 patients had genetic mutations, including CDKL5, pyruvate dehydrogenase, CFTR, CYP21A2, ISY1, KIF1A, KCNQ2, SCN9A, MTFMT, and NPHP1. All patients lacked significant risk factors to support a moderate to severe hypoxic-ischemic encephalopathy diagnosis. Treatment was changed in 2 patients because of confirmed genetic etiology. This study demonstrates the importance of identifying genetic comorbidities as potential contributors to a hypoxic-ischemic encephalopathy phenotype in neonates. Early identification of clinical factors that support an alternate diagnosis should be considered when the patient's clinical picture is not typical of hypoxic-ischemic encephalopathy and could aid in both treatment decisions and outcome prognostication.

Abstract
Background Increasing rates of obesity are of growing concern to maternal and child health as mothers with obesity are at risk of pregnancy complications. Infants of mothers with overweight/obese pre-pregnancy body mass index (BMI) may also be at risk of significant neurodevelopmental disorders. The relationship between maternal pre-pregnancy BMI and neurodevelopmental outcomes in preterm infants is not yet clearly defined. Objectives To determine the association of pre-pregnancy BMI of mothers of infants born <29 weeks gestational age (GA) and neurodevelopmental impairment (NDI) at 18-24 months corrected age (CA). Design/Methods Preterm infants born <29 weeks GA between January 2005 and December 2015 evaluated in the neonatal follow-up clinic at 18-24 months CA were included. Demographic characteristics as well as neurodevelopmental status including Bayley-III cognitive, language, and motor scores and sensory impairments were compared between three groups based on maternal pre-pregnancy BMI (BMI1 [18.5-24.9 kg/m2] vs. BMI2 [25-29.9 kg/m2] vs. BMI3 [≥30 kg/m2]) using univariate and multivariable regression models. The primary outcome was a composite of death or NDI. NDI was defined as the presence of Bayley-III <85 on one or more of the cognitive, motor, or language composite scores, any cerebral palsy (GMFCS ≥1), sensorineural or mixed hearing impairment, or unilateral or bilateral visual impairment. Results Of 771 eligible infants, 53 not seen in the follow-up clinic and 21 born to mothers with BMI <18.5 kg/m2 were excluded. Of the remaining 697 participants, 315 (45%) infants were in BMI1, 235 (34%) in BMI2, and 147 (21%) in BMI3 groups. Infants in BMI1, BMI2, and BMI3 groups had mean (SD) birth weight of 897 (231), 854 (208), and 867 (234) grams and median GA (IQR) of 27 (3), 26 (2), and 27 (3) weeks respectively. Rates of associated impairments are shown in Figure 1. The odds of a composite of death or NDI in BMI2 vs. BMI1 and BMI3 vs BMI1 groups were 1.33 (95%CI 0.86-2.06) and 0.76 (95%CI 0.47-1.22) respectively (Table 1). Infants born to mothers in the BMI2 group had twice the odds of scoring <85 on the Bayley-III language composite than those in BMI1 (adjusted odds ratio 2.06 [95% CI; 1.28-3.32]). Conclusion Pre-pregnancy body mass index was not associated with death or neurodevelopmental impairment in very preterm infants at 18-24 months corrected age. However, infants born to mothers who were overweight were more likely to have lower language scores. ![]()

Abstract
Background More than 1 in 4 preterm infants with bronchopulmonary dysplasia (BPD) develop BPD-associated pulmonary hypertension (BPD-PH) that is associated with significant morbidity. Data regarding neurodevelopmental outcomes with BPD-PH in preterm infants are lacking. Objectives To determine neurodevelopmental outcomes of preterm infants born < 29 weeks gestational age (GA) with BPD associated pulmonary hypertension at 18 to 24 months corrected gestational age (CGA). Design/Methods In this retrospective cohort study, preterm infants born < 29 weeks GA between January 2016 and December 2019 at level 3 Neonatal Intensive Care Units at Foothills Hospital in Calgary and the University of Texas Medical Branch (UTMB) in Galveston, who were evaluated at 18-24 months CGA in the neonatal follow-up clinics were included. We compared demographic factors, neurodevelopmental status including Bayley-III scores and sensory impairments between the two groups based on the presence of PH at 36 weeks CGA: Group I: BPD with PH and Group II: BPD without PH, using univariate and multivariable regression models. The primary outcome was a composite of death or neurodevelopmental impairments (NDI). NDI was defined as any cerebral palsy (GMFCS≥1), Bayley-III score < 85 on one or more of the cognitive, motor, or language composite scores, sensorineural or mixed hearing impairment or unilateral or bilateral visual impairment. Results Of 372 eligible infants, 118 (Group I [BPD-PH] =7, Group II [BPD with no PH] =111) were lost to follow up. Of the remaining 254 infants, 52 in Group I and 202 in Group II were followed at 18-24 months CGA. Group I and Group II had median (IQR) birth weight of 710g (323) and 815g (314) [p=0.004] and median gestational ages (IQR) were 25 weeks (2) and 26 weeks (2) [p=0.020], respectively . Rates of associated impairments are shown in Figure 1. Infants in BPD-PH group (Group I) were more likely to have mortality or NDI (adjusted Odds Ratio [aOR] 3.82; 95% CI: 1.17-12.41) (Table 1). Conclusion BPD-PH in preterm infants born < 29 weeks GA is associated with increased odds of the composite outcome of death or neurodevelopmental impairment and language delay at 18-24 months CGA. ![]()

Abstract
Abstract
Background
Consensus on definition and management of hypotension in preterm neonates is lacking. Owing to this, there are wide variations in the reported incidence of hypotension in premature infants, especially during first week of life. Inotropes can often cause vasoconstriction, which may alter brain perfusion especially in the absence of established cerebral autoregulation. Use of these drugs is associated with multiple short- and long-term morbidities.
Objectives
To evaluate the effect of quality improvement (QI) bundle on rate of inotrope use and associated morbidities.
Design/Methods
Inborn preterm neonates born at <29weeks gestational age (GA) and admitted to level III NICU were included. Neonates with major congenital malformations, congenital heart diseases, antenatal diagnosed genetic defects, and neonates admitted after 72 hours of age were excluded from the study. We implemented a QI bundle (Figure 1) focussing on first 72hours from birth which included delayed cord clamping, avoidance of routine echocardiography, addition of clinical criteria to define hypotension, factoring iatrogenic causes of hypotension (ruling out lung hyperinflation), and standardization of respiratory management. Rate of use of inotropes in the first 72hours of life along with acute brain injury and mortality before and after implementation of the QI bundle were compared. The balancing measure was the rate of ischemic lesions in the form of cPVL. Cranial ultrasound was performed to screen for brain injury. Study was approved by the local research ethics board (REB14-1466).
Results
We included 671 neonates (301 before and 364 after the implementation of the bundle) among which 6 neonates were excluded based on the criteria. QI bundle implementation was associated with significant reduction in overall use of inotropes (24% vs 7%, p<0.001), dopamine (18% vs 5%, p<0.001), and dobutamine (17% vs 4%, p<0.001). Rate of acute brain injury decreased significantly: Acute brain injury of any grade (34% vs 20%, p<0.001) and severe brain injury (15% vs 6%, p<0.001). There was no difference in incidence of cPVL (1% vs 1.4%, p=0.66). Associations remained significant after adjusting for confounding factors. The QI bundle implementation was associated with a significant reduction in the use of inotropes when analyzed based on the 6 monthly time intervals (p = 0.006) (Figure 2)
Conclusion
Our QI bundled approach resulted in reduction in inotrope use and associated brain morbidities in premature babies. Follow-up studies evaluating the impact of this initiative on long-term outcomes in survivors are required to complement findings of improved short-term outcomes seen in this study.

Abstract
OBJECTIVE To study the impact of an evidence-based neuroprotection care (NPC) bundle on long-term neurodevelopmental impairment (NDI) in infants born extremely premature. STUDY DESIGN An NPC bundle targeting predefined risk factors for acute brain injury in extremely preterm infants was implemented. We compared the incidence of composite outcome of death or severe neurodevelopmental impairment (sNDI) at 21 months adjusted age pre and post bundle implementation. RESULTS Adjusting for confounding factors, NPC bundle implementation associated with a significant reduction in death or sNDI (aOR, 0.34; 95% CI 0.17-0.68; P = 0.002), mortality (aOR, 0.31; 95% CI (0.12-0.79); P = 0.015), sNDI (aOR, 0.37; 95% CI: 0.12-0.94; P = 0.039), any motor, language, or cognitive composite score <70 (aOR, 0.48; 95% CI: 0.26-0.90; P = 0.021). CONCLUSION Implementation of NPC bundle targeting predefined risk factors is associated with a reduction in mortality or sNDI in extremely preterm infants.

Abstract
Primary Subject area
Neonatal-Perinatal Medicine
Background
Preterm infants who are also intrauterine growth restricted (IUGR) experience more frequent and earlier hemodynamic consequences of patent ductus arteriosus (PDA). This may be related to altered levels of prostaglandins or altered number or sensitivity of their receptors in IGUR infants. Few studies have examined the efficacy of pharmacologic therapy (non-steroidal anti-inflammatory drugs [NSAIDs]: indomethacin, ibuprofen, or acetaminophen) for PDA closure among preterm infants based on their degree of IUGR with differing results.
Objectives
Primary: To determine if the degree of IUGR [defined by birth weight (BW) z-score] affects the efficacy of pharmacologic PDA closure and rate of surgical PDA ligation in preterm infants. Secondary: To compare the side effects of NSAIDs and neonatal outcomes based on the severity of IUGR.
Design/Methods
This retrospective cohort study included infants of < 30 weeks’ GA, admitted to a tertiary neonatal intensive care unit (NICU) between 2010 and 2018, with hemodynamically significant PDA and treated with NSAIDs. Infants with major congenital anomalies, those who received prophylactic Indomethacin and those who died in the first 48 hours were excluded. Birth weight (BW) z-scores were calculated using Olsen nomograms and classified into 3 categories: z-score > −0.5 (normal), z-score −0.5 to −2.0 (mild to moderate growth restriction), z-score <−2 (severe IUGR). We compared responses to NSAID treatment and PDA ligation. Multivariate logistic regression analysis was done to examine the association of BW z-score and response to pharmacological therapy and subsequent surgical PDA ligation.
Results
Of the 1511 eligible infants, 769 (51%) had a diagnosis of PDA. Of 517 included infants, 323 (62.5%) had BW z-score >− 0.5, while 154 (29.8%) had z-scores − 0.5 to −2.0 and 40 (7.7%) had z-score < −2. Table 1 shows their demographic characteristics. Efficacy of first course of NSAIDs was not different among these birth weight groups (Table 2). There was no difference in the side effects and neonatal morbidities amongst the three groups (Table 2). Multivariate logistic regression analysis after controlling for GA, gender, antenatal steroids, C-section, and SNAP II showed that the odds of PDA ligation was significantly higher among infants with BW z-score < −2 (aOR 2.68, 95% CI 1.13- 6.36) but not among infants with z-score −0.5 to−2.0 (aOR 1.41, 95% CI 0.84, 2.39) as compared to z-score >-0.5.
Conclusion
Preterm severe IUGR infants with z-score < −2 have an associated increased risk of PDA ligation following pharmacologic treatment as compared to normally grown infants.

Abstract
Primary Subject area
Neonatal-Perinatal Medicine
Background
Pulmonary Hypertension (PH) is estimated to occur in 1 in 4 infants with Bronchopulmonary Dysplasia (BPD). The impact of PH in infants with BPD on their neurodevelopmental (ND) outcomes is uncertain.
Objectives
This systematic review aims to evaluate whether PH in infants with BPD is associated with ND delay.
Design/Methods
A systematic literature search was performed to identify studies that reported ND outcomes of infants with BPD (based on NIH definition) and PH (based on echocardiographic findings of PH at 36 weeks PMA). The primary outcome was ND delay in infants with pulmonary hypertension associated with BPD compared with BPD alone. Standardized developmental tests evaluated ND outcomes at 18-24 months corrected age (CA) and three years of age. Quality assessment of the studies was done using the Newcastle-Ottawa Quality Assessment for Cohort studies.
Results
Three retrospective cohort studies met the inclusion criteria. Two studies reported ND outcomes based on Bayley Scales of Infant and Toddler Development-III Edition in cognitive, language, and motor domains at 18-24 months CA (Table 1 and Figure 1). One study reported outcomes at 3 years, including overall developmental delay (Kyoto Scale of Psychological Development [KSPD] scores < 70) and cerebral palsy. The quality of all 3 studies was rated between good, fair, and poor. Pooled data from the 2 studies reporting outcomes at 18-24 months showed no difference between the 2 infant groups for Bayley cognitive score < 85 (Odds ratio [OR]: 3.78; 95% CI 0.87-16.52), Bayley language score < 85 (OR: 1.19; 95% CI0.57-2.49), and Bayley motor score < 85 (OR: 2.04; 95% CI 0.89-4.67). At 3 years of age, children in the BPD-PH group had an increased risk of developmental delay (DQ < 70 in all areas) compared with the BPD group (OR: 4.37; 95% CI 1.16-16.46), but no difference in the risk of cerebral palsy (OR: 0.57; 95%0.03-12.39).
Conclusion
PH in BPD is not associated with a developmental delay compared to BPD alone at 18-24 months CA. However, a single study showed infants in BPD-PH had delayed development at 3 years of age. A large prospective cohort study with longer multidisciplinary follow-up is required to confirm this.

Adverse childhood experiences and substance misuse in young people in India: results from the multisite cVEDA cohort. BMC Public Health 2021; 21:1920. [PMID: 34686158 PMCID: PMC8539836 DOI: 10.1186/s12889-021-11892-5] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2021] [Accepted: 09/07/2021] [Indexed: 12/01/2022] Open
Abstract
BACKGROUND Adverse childhood experiences (ACEs) increases vulnerability to externalising disorders such as substance misuse. The study aims to determine the prevalence of ACEs and its association with substance misuse. METHODS Data from the Consortium on Vulnerability to Externalising Disorders and Addictions (cVEDA) in India was used (n = 9010). ACEs were evaluated using the World Health Organisation (WHO) Adverse Childhood Experiences International Questionnaire whilst substance misuse was assessed using the WHO Alcohol, Smoking and Substance Involvement Screening Test. A random-effects, two-stage individual patient data meta-analysis explained the associations between ACEs and substance misuse with adjustments for confounders such as sex and family structure. RESULTS 1 in 2 participants reported child maltreatment ACEs and family level ACEs. Except for sexual abuse, males report more of every individual childhood adversity and are more likely to report misusing substances compared with females (87.3% vs. 12.7%). In adolescents, family level ACEs (adj OR 4.2, 95% CI 1.5-11.7) and collective level ACEs (adj OR 6.6, 95% CI 1.4-31.1) show associations with substance misuse whilst in young adults, child level ACEs such as maltreatment show similar strong associations (adj OR 2.0, 95% CI 1.1-3.5). CONCLUSION ACEs such as abuse and domestic violence are strongly associated with substance misuse, most commonly tobacco, in adolescent and young adult males in India. The results suggest enhancing current ACE resilience programmes and 'trauma-informed' approaches to tackling longer-term impact of ACEs in India.

Parental perception of neonatal transfers from level 3 to level 2 neonatal intensive care units in Calgary, Alberta: qualitative findings. BMC Health Serv Res 2021; 21:981. [PMID: 34535124 PMCID: PMC8449487 DOI: 10.1186/s12913-021-06967-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/22/2021] [Accepted: 08/27/2021] [Indexed: 11/10/2022] Open
Abstract
Background Retro-transfers from level 3 to 2 NICUs in Alberta’s regionalization of neonatal care system are essential to ensure the proper utilization of level 3 NICUs for complex neonatal cases. Parents often experience distress that relates to the transfer of their neonates to another hospital. Limited information is available regarding parental perceptions of distress during transfers for neonates requiring care between NICUs in the current Canadian context. The objective of this study was to investigate: 1) what caused parents distress and could be changed about the transfer process and 2) the supports that were available to help ease parental distress during the transfer process. Methods Parents of singleton infants retro-transferred from level 3 to 2 NICUs in Calgary, Alberta between January 1, 2016, and December 31, 2017, were invited to participate in the study. Questionnaires were self-administered by one parent per family. A thematic deductive approach was employed by the researchers to analyze the qualitative data. Results Our response rate was 39.1% (n = 140). We found three themes for causes of parental distress and supports available to ease parental distress during the transfer, including communication between staff members and parents, details about the transfer process, and the care received throughout and shortly after the transfer process. Conclusion Parents should receive at least 24 h of notice, regular transfer updates, employ anticipatory preparation strategies, and foster more open communication between parents and health care professionals to help ensure parental satisfaction.

Post-hemorrhagic ventricular dilatation: inter-observer reliability of ventricular size measurements in extremely preterm infants. Pediatr Res 2021; 90:403-410. [PMID: 33184496 DOI: 10.1038/s41390-020-01245-0] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/22/2020] [Revised: 10/09/2020] [Accepted: 10/16/2020] [Indexed: 11/09/2022]
Abstract
BACKGROUND Post-hemorrhagic ventricular dilatation (PHVD) in preterm infants can be assessed with ventricular size indices from cranial ultrasound. We explored inter-observer reliability of these indices for prediction of severe PHVD. METHODS For all 139 infants with IVH, serial neonatal ultrasound at 3 time points (days 4-7, day 14, 36 weeks PMA) were assessed independently by 3 observers with differing levels of training/experience. Ventricular index (VI), anterior horn width (AHW), and fronto-temporal horn ratio (FTHR) were measured and used to diagnose PHVD. For all, inter-observer reliability and predictive values for receipt of surgical intervention were calculated. RESULTS Inter-observer reliability for all observers varied from poor to excellent, with higher reliability for VI/AHW (ICC 0.49-0.84/0.51-0.81) than FTHR (0.41-0.82), particularly from the second week. Good-excellent inter-expertise reliability was found between observers with ample experience/training (0.65-0.99), particularly for VI and AHW, while poor-moderate when comparing with an inexperienced observer (0.28-0.88). Slightly higher predictive value for PHVD intervention (n = 12) was found for AHW (AUC 0.86-0.96) than for VI and FTHR (0.80-0.96/0.80-0.95). CONCLUSIONS AHW and VI are highly reproducible in experienced hands compared to FTHR, with AHW from the second week onwards being the strongest predictor for receiving surgical intervention for severe PHVD. AHW may aid in early PHVD diagnosis and decision-making on intervention. IMPACT While ventricular size indices from serial cUS are superior to clinical signs of increased intracranial pressure to assess PHVD, questions remained on their inter-observer reproducibility and reliability to predict severity of PHVD. AHW and VI are highly reproducible when performed by experienced clinicians. AHW from the second week of birth is the strongest predictor of PHVD onset and severity. AHW, combined with VI, may aid in early PHVD diagnosis and decision-making on need for surgical intervention. Consistent use of these indices has the potential to improve PHVD management and therewith the long-term outcomes in preterm infants.

Abstract
OBJECTIVE To compare neurodevelopmental outcomes of large and appropriate for gestational age (LGA, AGA) infants <29 weeks' gestation at 18-24 months of corrected age. STUDY DESIGN Retrospective cohort study using the Canadian Neonatal Network and Canadian Neonatal Follow-Up Network databases. Primary outcome was a composite of death or significant neurodevelopmental impairment (NDI), defined as severe cerebral palsy, Bayley III cognitive, language and motor scores of <70, need for hearing aids or cochlear implant and bilateral visual impairment. Univariate and multivariable logistic analyses were applied for outcomes. RESULTS The study cohort comprised 170 LGA and 1738 AGA infants. There was no difference in significant NDI or individual components of the Bayley III between LGA and AGA groups. LGA was associated with the increased risk of death by follow-up, 44/170 (25.9%) vs. 320/1738 (18.4%) (aOR: 1.60 95% CI: 1.00-2.54). CONCLUSIONS Risk of NDI was similar between LGA and AGA infants.

Abstract
Introduction Currently, Buprenorphine maintenance therapy (BMT) is an evidence-based treatment in retaining patients who are dependent on opioids. However, factors influencing retention are often measured objectively. Studies on patient’s perspectives on take home BMT in developing countries are limited. Objectives This study examines the potential factors influencing treatment compliance in the early phase of Buprenorphine maintenance treatment from the patient’s perspective Methods Participants (n=89) who were initiated on BMT were recruited and followed after six weeks. A semi-structured interview was conducted with 62 patients who remained in treatment and 24 patients who dropped out of the study Results Based on the semi qualitative analysis some of the factors which facilitated the patient’s retention in treatment were: (1) Effectiveness in blocking withdrawal symptoms (2) effectiveness in reducing their cravings and controlling their opioid use (3) decreased fear of withdrawal and/or missing doses(4) improvement in the quality of life(5) patient-related factors like family support (6) effectiveness of the treatment program. Around nine percent of patients reported family support as the reason for retention, which is not noticed in other studies. Barriers reported by the patients while on medication were: (1) negative effect experienced with medication (2) program related difficulties like distance, unavailability (3) major life event interrupting the treatment (4) patient-related factors like low mood, financial constraints. Conclusions Understanding factors associated with barriers to treatment provide insights into preventable factors that contribute to premature drop out from BMT and to improve clinical practice, policy decisions, or future research.

Abstract
OBJECTIVE The primary objective of this study was to determine the overall parental satisfaction with retro-transfers from a level 3 to a level 2 Neonatal Intensive Care Unit (NICU). The secondary objectives were to explore factors that caused parental satisfaction associated with retro-transfer and investigate the factors that could be modified to improve the retro-transfer process. METHODS This is a retrospective cross-sectional study. Questionnaires were mailed to all parents of infants transferred from level 3 to level 2 NICUs from 2016 to 2017. Independent samples t-tests, Spearman's rank correlations, and multiple logistic regression analyses were conducted to identify factors associated with parental retro-transfer satisfaction. RESULTS Our response rate was 39.1% (n = 140). Of all parents, 64.29% parents were extremely satisfied with the overall retro-transfer process. In our bivariate analyses, multiple factors were found to be strongly associated with parental retro-transfer satisfaction, including parental level of education, the amount of notice and rationale given for the retro-transfer and the level of parental communication and engagement with their infant's healthcare team before and after transfer. Multiple logistic regression analyses revealed that when questions regarding the retro-transfer were answered and the level 2 NICU team demonstrated a concrete understanding of the infant's medical issues and history, parental satisfaction increased. CONCLUSION Majority of parents were satisfied with the retro-transfer process. However, close collaboration and ongoing and open lines of communication between parents and the level 3 NICU healthcare teams will increase parental retro-transfer satisfaction rates.

Abstract
BACKGROUND We assessed the impact of an evidence-based neuroprotection care bundle on the risk of brain injury in extremely preterm infants. METHODS We implemented a neuroprotection care bundle consisting of a combination of neuroprotection interventions such as minimal handling, midline head position, deferred cord clamping, and protocolization of hemodynamic and respiratory managements. These interventions targeted risk factors for acute brain injury in extremely preterm infants (born at gestational age less than 29 weeks) during the first three days of birth. Implementation occurred in a stepwise manner, including care bundle development by a multidisciplinary care team based on previous evidence and experience, standardization of outcome assessment tools, and education. We compared the incidence of the composite outcome of acute preterm brain injury or death preimplementation and postimplementation. RESULTS Neuroprotection care bundle implementation associated with a significant reduction in acute brain injury risk factors such as the use of inotropes (24% before, 7% after, P value < 0.001) and fluid boluses (37% before, 19% after, P value < 0.001), pneumothorax (5% before, 2% after, P value = 0.002), and opioid use (19% before, 7% after, P value < 0.001). Adjusting for confounding factors, the neuroprotection care bundle significantly reduced death or severe brain injury (adjusted odds ratio, 0.34; 95% confidence interval, 0.20 to 0.59; P value < 0.001) and severe brain injury (adjusted odds ratio, 0.31; 95% confidence interval, 0.17 to 0.58; P < 0.001). CONCLUSIONS Implementation of neuroprotection care bundle targeting predefined risk factors is feasible and effective in reducing acute brain injury in extremely preterm infants.

Abstract
Aim To evaluate the impact of outreach education targeting neuroprotection on outcomes of outborn infants with moderate-to-severe hypoxic ischemic encephalopathy (HIE). Methods A retrospective cohort study of infants admitted with moderate-to-severe HIE was conducted following the implementation of outreach education in January 2016. Key interventions were early identification and referral of infants with encephalopathy utilizing telemedicine and a centralized communication system, hands-on simulation, and interactive case discussion and dissemination of clinical management guidelines and educational resources. The association between the intervention and a composite outcome of death and/or severe brain injury on brain magnetic resonance imaging (MRI) was tested controlling for the confounding factors. Results Of 165 neonates, 37 (22.4%) died and/or had a severe brain injury. This outcome decreased from 35% (27/77) to 11% (10/88) following the implementation of outreach education (P<0.001). Eligible infants not undergoing therapeutic hypothermia within 6 hours from birth decreased from 19.5% (15/77) to 4.5% (4/88). The use of inotropes decreased from 49.3% (38/77) to 19.6% (13/88). Any core temperature below 33°C was recorded for 20/53 (38%) before and 16/78 (21%) after, while those within the target range of 33°C to 34°C at admission to a tertiary care facility increased from (15/53) 28% to (51/88) 58%. Outreach education was independently associated with decreased composite outcome of death and/or severe brain injury on MRI (adjusted odds ratio 0.2; 95% confidence interval 0.07 to 0.52). Conclusion Outreach education targeting neuroprotection for infants with moderate-to-severe HIE was associated with a reduction in death and/or severe brain injury.

Abstract
A term, large for gestational age male newborn, was admitted to the neonatal intensive care unit with meconium aspiration syndrome and severe hypoxic-ischaemic encephalopathy. The baby was treated with therapeutic hypothermia using a total body cooling blanket. After 48 hours, the baby developed tender, indurated subcutaneous nodules consistent with subcutaneous fat necrosis (SCFN). The lesions started initially over the back but gradually spread to cover both shoulders, upper arms, chest area and both thighs. On day 19 of life, multiple small nodules on the back softened and coalesced to form one sizeable fluctuant swelling over the thoracolumbar area. Over a few hours, the swelling rapidly progressed to a large, tense mass with sloughing of the gangrenous overlying skin. This unusual complication of SCFN required surgical intervention for evacuation and debridement of the haematoma followed by graft repair of the skin defect.

Abstract
OBJECTIVES Brain injury in preterm neonates may cause clinical deterioration and requires timeous bedside diagnosis. Teaching cranial ultrasound (US) skills using fragile preterm neonates is challenging. The purpose of this study was to test the effectiveness and feasibility of using task-trainer computer-based simulators and US-suitable cranial phantoms in combination with teaching sessions in teaching novices to perform focused cranial US evaluations for identifying substantial intraventricular hemorrhage. METHODS This was a prospective interventional educational study targeting participants with no prior skills in neonatal cranial US. Participants attended a 2-day training workshop, with didactic and hands-on interactive sessions using computer-based and 3-dimensional printed phantom simulators. Participants then performed a cranial US scan on a healthy neonate to assess the diagnostic quality of the images acquired. Individual precourse and postcourse knowledge tests were compared. To test recall, participants also submitted US images acquired on neonates within 3 and 6 months of attending the course. RESULTS Forty-five participants completed the training modules. Mean knowledge scores increased significantly (in brain anatomy, brain physiology, intracranial disorders, and US physics domains). Thirty-eight cranial US scans were acquired during the course, 22 within 3 months after completion, and 34 within 6 months after completion. Thirty-two (84%) of the initial 38 case images, 17 (77%) of 22 images submitted within 3 months, and 32 (94%) of 34 images submitted within 6 months after course completion were of diagnostic quality. CONCLUSIONS A structured training module with didactic and hand-on training sessions using simulators and phantoms is feasible and supports training of clinicians to perform focused cranial US examinations.

Abstract
BACKGROUND Despite the introduction of therapeutic hypothermia, infants with moderate-to-severe hypoxic-ischemic encephalopathy remain at risk of mortality and morbidity. A dedicated service with standardized management protocols and improved communication may help improve care. We aimed to evaluate the impact of a dedicated neonatal neurocritical care service on short-term outcomes in infants with hypoxic-ischemic encephalopathy. METHODS We performed a retrospective cohort study (July 2008 to December 2017) on term and near-term infants admitted to two tertiary neonatal intensive care units with moderate-to-severe hypoxic-ischemic encephalopathy, before and after neonatal neurocritical care service implementation. The primary outcome was brain magnetic resonance imaging findings consistent with those of hypoxic-ischemic encephalopathy. Secondary outcomes included the cooling initiation rate, hospital stay duration, antiseizure medication use, and inotrope use. Regression analysis and interrupted time series analysis were performed after adjusting for confounding factors. RESULTS In total, 216 infants with moderate-to-severe hypoxic-ischemic encephalopathy were analyzed-109 before and 107 after neonatal neurocritical care implementation. After adjusting for confounding factors, there was a significant reduction in primary outcomes (adjusted odds ratio: 0.3, confidence interval: 0.15 to 0.57, P < 0.001) after neonatal neurocritical care implementation. Average hospital stay duration reduced by 5.2 days per infant (P = 0.03), identification of eligible infants for cooling improved (P < 0.001), antiseizure medication use reduced (P = 0.001), and early inotropes use reduced (P = 0.04). CONCLUSION Implementation of a neonatal neurocritical care service associated with decreased brain injury shortened the hospital stay duration and improved the care of infants with moderate-to-severe hypoxic-ischemic encephalopathy.

Factors Affecting Stabilization Times in Neonatal Transport. Air Med J 2019; 38:334-337. [PMID: 31578970 DOI: 10.1016/j.amj.2019.06.005] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2019] [Revised: 05/23/2019] [Accepted: 06/13/2019] [Indexed: 06/10/2023]
Abstract
OBJECTIVE During transport, the time spent in stabilizing sick infants before repatriation is crucial in optimizing the outcome and effective use of resources. The study aim was to assess individual components of neonatal transport time to identify opportunities to minimize delay, optimize care, and improve the overall efficiency of transport. METHODS A single-center prospective observational study conducted at McMaster Children's Hospital, Hamilton, Ontario, Canada, with a dedicated transport team for over 12 months. The stabilization time was defined as the time interval between arrival and departure from the referring hospital. RESULTS Of 223 neonatal transfers, 67 required no procedural or therapeutic intervention before mobilization to the receiving unit, with a mean stabilization time of 113 ± 52 minutes. In 156 transport events, 1 or more interventions were required, with a significantly higher mean stabilization time of 165 ± 89 minutes (P < .0001). CONCLUSION This study found that the local stabilization time was more than 1.5 times that of the comparable published data. The reasons identified for this delay were mostly because of waiting times for vehicle mobilization, waiting for blood and radiology results, and bed availability. Modifying these factors could save up to 28% of the stabilization time.

Abstract
BACKGROUND Limited point-of-care ultrasound skills for ultrasound-naïve neonatal transport clinicians could enhance clinical evaluation and decision making. Teaching Respiratory Therapists and Nurses to assess cardiac filling and contractility may be feasible. METHODS Prospective educational study using educational materials, didactic theoretical, and hands-on practical sessions, followed by assessment of practical and theoretical skills. RESULTS A total of 18 participants completed the study meeting the predefined standard, proving feasibility. Nine (50%) participants had ≤ 10 years of NICU experience. The mean time required for complete training was 8.6 ± 2.1 hours. Time was spent on average on 269 ± 104 minutes for hands-on practice, 171 ± 96 minutes on didactic training, and 76 ± 16 minutes on testing sessions. The median number of hands-on sessions per participant was 5 [Interquartile range (IQR) 5, 7]. The median number of infants required to complete training was 9 infants (IQR 7, 11). RRTs required less time than RNs. Evaluations and feedback from participants on the training program was positive. CONCLUSION Neonatal RNs and RTs can be trained to perform focused cardiac ultrasound examinations with average time of 8.6 hours. This skill could enhance clinical care on neonatal transport with appropriate interventions to manage suspected hypotension or shock.

Abstract
OBJECTIVE To evaluate the prevalence, risk factors, and optimal timing of echocardiogram for pulmonary hypertension (PH) in infants with bronchopulmonary dysplasia (BPD). DESIGN In this prospective study, infants with gestational age (GA) <30 weeks admitted to a tertiary NICU between July 2015 and June 2017 who required positive pressure ventilation or oxygen therapy at ≥28 days of life were evaluated with serial echocardiograms at study enrollment (4-6 weeks of age), 32 weeks (only for ≤25 weeks), 36, and 40 weeks post-menstrual age (PMA) for PH. RESULTS Of 126 infants (mean birth weight 858 ± 221 g; mean GA 26.1 ± 1.6 wks), 48 (38%) developed PH at any time during their hospital stay. The first study echocardiogram was performed at a median age of 31 weeks PMA. The prevalence of PH was 36/126 (28.5%) at enrollment, at 6/30 (20%) at 32 weeks, 24/111 (21.6%) at 36 weeks, and 10/59 (17%) at 40 weeks. No new cases of PH were identified at 40 weeks. At 36 weeks, none of the infants with mild BPD had PH, whereas 20% of moderate and 32% of severe BPD infants had PH. After controlling for confounding variables severe BPD (OR 3.31, 95%CI 1.12, 9.74), and ventilator associated pneumonia (VAP) (OR 17.9, 95%CI 3.9, 82.11) remained independent risk factors for BPD-associated PH. CONCLUSION Echocardiographic screening for PH can be safely restricted to infants with moderate or severe BPD at 36 weeks PMA. We identified VAP as an independent risk factor for PH.

Abstract
Introduction: Extremely premature infants are susceptible to fluctuations in cerebral blood flow due to immaturity of cerebral autoregulation. Inotropes may cause rapid changes to systemic blood pressure and consequently cerebral blood flow, especially within the first 72 hours of life. This period is recognized to carry the greatest risk for cerebral hemorrhage. This study evaluates the incidence of death and/or severe brain injury in extremely preterm infants treated with inotropes in the first 72 hours of life.Methods: Prospective cohort study of infants born ≤29+0 weeks gestational age (GA) between January 2013 and December 2016. Severe brain injury was defined based on head ultrasound as presence of: grade III or IV intraventricular hemorrhage (IVH), moderate to severe post-hemorrhagic ventricular dilatation (PHVD), or cystic periventricular leukomalacia (cPVL). The association between inotrope use and death and/or brain injury was explored via logistic regression controlling for predefined confounding risk factors.Results: Of 497 eligible infants, 97 (19.5%) received inotropes during the first 72 hours. GA at birth, birth weight (BW), and 5-minute Apgar scores were lower among infants who received early inotropes compared to those not treated with inotropes. A stepwise logistic regression of the predefined confounding factors showed GA, exposure for antenatal steroids, and admission hypothermia to be significant confounding factors. Adjusting for those factors, early use of inotropes was associated with increased risk of death and/or severe brain injury (AOR 4.5; 95%CI: 2.4-8.5), severe brain injury (AOR 4.2; 95% CI: 1.9-8.9), and IVH of any grade (AOR 2.9; 95%CI: 1.7-4.9).Conclusion: Early inotropes use was associated with higher risk of death and/or severe brain injury. Strict indications and strategies for minimizing inotrope use while preventing hypotension should be implemented in the early postnatal care of infants at risk for severe brain injury.

Abstract
Objectives: To assess maternal and neonatal risk factors for intraventricular hemorrhage (IVH). To examine the association of patent ductus arteriosus (PDA) and its treatment, with IVH and its severity. Study design: In this retrospective cohort study, we included preterm neonates born at <29 weeks, admitted to a tertiary level III Neonatal Intensive Care Unit in Calgary, Canada, between 2013 and 2016, who had a head ultrasound in the first 7 days of life. A subset analysis included neonates who also had cardiac ultrasound in the first 3 days of life. Results: Of the 495 neonates, 121 (24.4%) had IVH of any grade and 48 (9.7%) had severe IVH. Identified risk factors were small birth gestation and weight, lack of antenatal corticosteroids, maternal chorioamnionitis, Apgar score <5 at 5 min, umbilical cord pH < 7, respiratory distress syndrome, early onset sepsis, hypercapnia, pCO2 fluctuations, prolonged intubation, inhaled nitric oxide, inotropes or normal saline boluses, metabolic derangements, opioids infusions, and bicarbonate/THAM therapy. In a primary analysis of the total cohort, when the decision to treat a PDA was used as a surrogate marker of its clinical significance, a PDA requiring treatment was associated with a higher risk of IVH. There was no significant difference in the incidence of IVH between neonates with early treatment of a clinically significant PDA compared to late, however early indomethacin treatment was associated with reduced severity of IVH. In the subset analysis, the presence of a hemodynamically significant PDA (hs-PDA) was not associated with a higher probability of IVH. Of those with severe IVH, 18 (55%) had a hs-PDA; this is clinically but not statistically significant. Conclusions: Identified risk factors should be the target of IVH reduction bundles. Early indomethacin treatment for a clinically significant PDA may reduce IVH severity.

Abstract
OBJECTIVE Significant haemodynamic changes occur at delivery impacting organ blood flow distribution. We aimed to characterise Doppler indices patterns over time in three different organs (brain, gut and kidney) and test them as measures of vascular resistance. DESIGN Observational cohort study. Serial Doppler interrogations of the anterior cerebral, superior mesenteric and renal arteries within 2 hours, 2-6, and 24 hours of life, in combination with central haemodynamic data. PATIENTS Healthy, near-term (>36 weeks of gestation) neonates. OUTCOME MEASURES Pulsatility (PI) and Resistance Indices (RI) patterns and organ-specific conductances, detailed echocardiographic haemodynamic measures. RESULTS Twenty-one babies were studied. Doppler morphology and adaptation patterns were distinctly different between the organs (brain, gut and kidney) supporting autonomous vascular regulatory effects. The PI differentiated especially between kidney and other organ flow consistently over time. PI and RI for all three organs decreased. The variance in organ conductance did not explain the variance in 1/PI, indicating that PI is not a measure of resistance. Superior mesenteric artery had the highest velocity with 72 cm/s. Non-invasively acquired pilot serial values in a normal population are given. Patent ductus arteriosus flow remained open at discharge for 36%. CONCLUSIONS Haemodynamic transitioning patterns assessed by serial Dopplers in healthy near-term neonates differ in brain, gut and kidney: Doppler waveform morphology differs, and PI differentiates renal Doppler morphology, compared with the other organs. While PI and RI decline for all organs, they do not measure resistance. Brain artery velocity increases, mesenteric perfusion is variable and renal Vmax decreases.

Abstract
Neonatal abstinence syndrome (NAS) secondary to maternal drug use is a well-recognized clinical entity. We present a novel case of moderately severe NAS in a term infant whose mother was self-medicating with kratom tea. The baby required oral morphine for NAS. After 12 days in neonatal intensive care unit, she was discharged on oral morphine which was discontinued after 2 months. Kratom, a psychoactive herb with opioid activity, has traditionally been used as a stimulant to boost energy, cure cough, depression, pain, sickness and a substitute for opium. Although well known in South East Asia and Africa, this drug is less familiar to physicians in North America. It is undetectable by standard urine drug screening and is being sold as a legal herbal remedy. This is the first report of a newborn developing significant NAS after maternal use of kratom tea. We believe physicians should be aware of this 'new' risk to newborns.

Abstract
Context: Recent upsurge in referral of patients with compromised left ventricular (LV) function for cardiac surgery has led to an increasing use inotropes to achieve improvement of tissue perfusion in the perioperative period. Aims and Objectives: To compare the hemodynamic effects and immediate postoperative outcomes with levosimendan and dobutamine in patients with moderate to severe LV dysfunction undergoing off-pump coronary artery bypass grafting (OPCAB). Settings and Design: University teaching hospital, randomized control study. Materials and Methods: Eighty patients were randomly divided into two groups of 40 each. Group I received levosimendan at 0.1 μg/kg/min and Group II received dobutamine at 5 μg/kg/min. Hemodynamic data were noted at 30 min, during obtuse marginal grafting, 1, 6, 12, and 24 h after surgery. Heart rate (HR), mean arterial pressure (MAP), pulmonary capillary wedge pressure (PCWP), cardiac index (CI), systemic vascular resistance index (SVRI) and pulmonary vascular resistance index (PVRI), left ventricular stroke work index (LVSWI) and right ventricular stroke work index (RVSWI), mixed venous oximetry (SvO2), and lactate were measured. Statistical Analysis Used: Chi-square and Student's t-test. Results: The HR, MAP, PCWP, SVRI, and PVRI were lower in Group I when compared to Group II. Group I patients showed a statistically significant increase in LVSWI, RVSWI, and CI, when compared to Group II. Comparatively, Group I patients maintained higher SvO2 and lower lactate levels. Duration of ventilation, Intensive Care Unit (ICU), and hospital stay were lower in Group I. Conclusions: Levosimendan was associated with statistically significant increase in indices of contractility (CI, LVSWI, and RVSWI) and decrease in PCWP during and after OPCAB. Levosimendan group had lower incidence of atrial fibrillation, shorter length of ICU, and hospital stay.

Abstract
BACKGROUND Approximately 1 in 10 pregnancies is affected by meconium passage at delivery, which can result in meconium aspiration syndrome (MAS). MAS can cause respiratory complications and, very rarely, death. Antibiotics have been prescribed for neonates exposed to meconium in amniotic fluid, with the intention of preventing infection due to potential bacterial contaminants. OBJECTIVES We conducted this review to assess the efficacy and safety of antibiotics for:1. prevention of infection, morbidity, and mortality among infants born through meconium-stained amniotic fluid (MSAF) who are asymptomatic at birth; and2. prevention of infection, morbidity, and mortality among infants born through MSAF who have signs and symptoms compatible with meconium aspiration syndrome (MAS). SEARCH METHODS We performed a literature search using the following databases: MEDLINE (1966 to July 2016); Embase (1980 to July 2016); the Cumulative Index to Nursing and Allied Health Literature (CINAHL; 1982 to July 2016); and the Cochrane Central Register of Controlled Trials (CENTRAL; 2016, Issue 7) in the Cochrane Library. We also searched clinical trials databases, conference proceedings, and reference lists of retrieved articles. SELECTION CRITERIA We included randomised and quasi-randomised controlled trials that compared antibiotics administered via any route versus placebo or no treatment for prevention of infection among neonates exposed to MSAF, or who developed MAS. We excluded cohort, case control, and any other non-randomised studies and applied no language restrictions. We included studies of term and preterm infants, and we included studies examining use of any antibacterial antibiotics. We included studies that reported on any outcomes of interest. DATA COLLECTION AND ANALYSIS We assessed the methodological quality of included trials by reviewing information provided in study reports and obtained by personal communication with study authors. We extracted data on relevant outcomes, estimated effect size, and reported values as risk ratios (RRs), risk differences (RDs), and mean differences (MDs), as appropriate. We conducted subgroup analyses for treatment of MAS and for prophylaxis (asymptomatic neonates exposed to meconium). MAIN RESULTS Four randomised controlled studies including a total of 695 participants were eligible for inclusion. Three studies evaluated neonates with MAS, and one study assessed asymptomatic neonates exposed to meconium in amniotic fluid. These studies exhibited varying degrees of methodological rigour: Two studies were at low risk of bias, and two were at unclear risk. We graded evidence derived from these studies as low quality. We downgraded overall evidence owing to the large number of participants lost to follow-up in one trial, the small sample sizes of all trials, and unclear methodological details provided for two trials.The primary outcome was risk of early- and late-onset neonatal sepsis. Antibiotics did not decrease the risk of sepsis in neonates with a diagnosis of MAS (RR 1.54, 95% confidence interval (CI) 0.27 to 8.96; RD 0.00, 95% CI -0.02 to 0.03; 445 participants, three studies; I² = 0%) nor in asymptomatic neonates exposed to meconium in amniotic fluid (RR 0.76, 95% CI 0.25 to 2.34; RD -0.01, 95% CI -0.07 to 0.04; 250 participants, one study; I² = 0%). Results show no significant differences in mortality or duration of stay in hospital between groups given antibiotics and control groups of symptomatic and asymptomatic neonates. One study in asymptomatic neonates reported a significant reduction in duration of mechanical ventilation for the control group compared with the antibiotic group (MD 0.26, 95% CI 0.15 to 0.37; 250 participants, one study; I² = 0%). AUTHORS' CONCLUSIONS Upon review of available evidence, we found no differences in infection rates following antibiotic treatment among neonates born through meconium-stained fluid and those with meconium aspiration syndrome. The overall quality of evidence is low owing to the small number of included studies. Well-controlled studies of adequate power are needed.

Abstract
BackgroundPrevious studies have reported depressive symptoms in patients with persistent delusional disorder (PDD). Patients with PDD and depression may need antidepressants for treatment.AimThe aim of the study was to compare the sociodemographic profile, clinical presentation and treatment response in patients with PDD with and without comorbid depressive symptoms.MethodsWe conducted a retrospective chart review of patients diagnosed with PDD (ICD-10) from 2000 to 2014 (n = 455). We divided the patients into PDD + depression (n = 187) and PDD only (n = 268) for analysis.ResultsOf the 187 patients with PDD + D, only eighteen (3.9%) were diagnosed with syndromal depression. There were no significant differences in sociodemographic profile including sex, marital and socioeconomic status (all P > 0.05). PDD + D group had a significantly younger age at onset ([PDD + D: 30.6 9.2 years vs. PDD: 33.5 11.1 years]; t = 2.9, P < 0.05). There was no significant difference between the clinical presentation including mode of onset, the main theme of their delusion and secondary delusions (all P > 0.3). However, comorbid substance dependence was significantly higher in patients with PDD only. (χ2 = 5.3, P = 0.02). In terms of treatment, response to antipsychotics was also comparable ([> 75% response: PDD + D = 77/142 vs. PDD = 106/179); χ2 = 1.9, P = 0.3). There was a significant difference between the two groups in terms of antidepressant treatment ([PDD + D = 32/187; 17% vs PDD: 17/268; 6%), χ2 = 12.9, P = 0.001).DiscussionPatients with PDD + D had significantly earlier onset of illness. These patients may require antidepressants for treatment.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
AIM To determine the feasibility of introducing video recording (VR) of neonatal resuscitation (NR) in a perinatal centre.
METHODS This was a prospective cohort quality improvement study on preterm infants and their caregivers. Based on evidence and experience of other centers using VR intervention, a contextually relevant implementation and evaluation strategy was designed in the planning phase. The components of intervention were pre-resuscitation team huddle, VR of NR and video debriefing (VD), all occurring on the same day. Various domains of feasibility and sustainability as well as feasibility criteria were predefined. Data for analysis was collected using quantitative and qualitative methods.
RESULTS Seventy-one caregivers participated in VD of 14 NRs facilitated by six trained instructors. Ninety-one percent of caregivers perceived enhanced learning and patient safety and, 48 issues were identified related to policy, caregiver roles, and latent safety threats. Ninety percent of caregivers expressed their willingness to participate in VD activity and supported the idea of integrating it into a resuscitation team routine. Eighty-three percent and 50% of instructors expressed satisfaction with video review software and quality of audio VR. No issues about maintenance of infant or caregivers’ confidentiality and erasure of videos were reported. Criteria for feasibility were met (refusal rate of < 10%, VR performed on > 50% of occasions, and < 20% caregivers’ perceiving a negative impact on team performance). Necessary adaptations to enhance sustainability were identified.
CONCLUSION VR of NR as a standard of care quality assurance activity to enhance caregivers’ learning and create opportunities that improve patient safety is feasible. Despite its complexity with inherent challenges in implementation, the intervention was acceptable, implementable, and potentially sustainable with adaptations.

Abstract
Abstract
BACKGROUND: Compromised neonates do not receive placental transfusion (PT), but receive immediate cord clamping to facilitate resuscitation. Animal studies suggest possible benefit of resuscitation during PT.
OBJECTIVES: To study the feasibility of initiating resuscitative care during PT for 90s in preterm infants.
DESIGN/METHODS: We designed a mobile, battery powered resuscitation platform (iNSPiRe) that contains a scale, warm gel mattress, oxygen and air tanks, blender, T piece resuscitator, pulse oximeter (PO), and suction device (Fig. 1). Resuscitative care included initial steps, and respiratory support at 30s following Neonatal Resuscitation Program guidelines. Thermoregulation was maintained using a hat, warmed blankets, and gel mattress. Heart rate was auscultated at 30, 60 and 90s. PO was placed on the right wrist/hand. The cord was clamped at 90s. The baby and platform were mobilized from mother’s bedside to a radiant warmer by one provider, while another provider maintained respiratory support. Once on the warmer, axillary temperature (AT) was measured. Resuscitation interventions and management during first 24 hours were recorded.
RESULTS: Seven infants born vaginally, median (range) gestational age (GA) was 30 weeks (28 to 36) and birth weight 1500g (1270 to 2650), were managed using iNSPiRe. Table 1 shows time (T) to initiate interventions, cord pH and Apgar scores. Five infants received continuous positive airway pressure (CPAP) and one received positive pressure ventilation; none had hypotension, pneumothorax, or received surfactant. No incidence of intraventricular hemorrhage.
CONCLUSION: It is feasible to commence resuscitative care during PT in infants ≥30 weeks' GA for 90s. Further research is needed to assess the feasibility in smaller and sicker preterm infants.

Abstract
IntroductionThere is a lack of pharmacological trials studying drug response in Persistent Delusional Disorder (PDD) to guide clinical practice. Available reviews of retrospective data indicate good response to second-generation antipsychotics, but even such data from India is sparse.Objectives and aimsWe aimed to compare the response of acute PDD to risperidone and olanzapine in our retrospective review.MethodsWe conducted a retrospective chart review of patients diagnosed with PDD (ICD-10) from 2000 to 2014 (n = 455) at our Center. We selected the data of patients prescribed either olanzapine or risperidone for the purpose of this analysis. We extracted data about dose, drug compliance and response, adverse effects, number of follow-up visits and hospitalizations. The study was approved by the Institute Ethics Committee.ResultsA total of 280/455 (61%) were prescribed risperidone and 86/455 (19%) olanzapine. The remaining (n = 89; 20%) had received other antipsychotics. The two groups were comparable in socio-demographic and clinical characteristics of PDD. Compliance was good and comparable in both groups (> 80%, P = 0.2). Response to treatment was comparable in both groups (85% partial response and > 52% good response, all P > 0.3). Olanzapine was effective at lower mean chlorpromazine equivalents than risperidone (240 vs. 391, P < 0.05).ConclusionOur study indicates a good response to both risperidone and olanzapine, if compliance to treatment can be ensured. In the absence of specific treatment guidelines for PDD, second-generation antipsychotics like risperidone and olanzapine offer good treatment options for this infrequently encountered and difficult to treat psychiatric disorder.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Triplets with neonatal alloimmune thrombocytopenia due to antibodies against human platelet antigen 1a. Transfusion 2016; 56:1166-1170. [PMID: 26813079 DOI: 10.1111/trf.13494] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2015] [Revised: 11/25/2015] [Accepted: 12/17/2015] [Indexed: 11/28/2022]
Abstract
BACKGROUND Neonatal alloimmune thrombocytopenia (NAIT) has been reported only rarely in twins and not at all, to our knowledge, in triplets. CASE REPORT Nonidentical triplets were born with severe thrombocytopenia. Nadir platelet (PLT) counts were 17 × 109 , 12 × 109 , and 10 × 109 /L. NAIT was confirmed by an incompatibility for human PLT antigen (HPA)-1a and the presence of maternal anti-HPA-1a. The maternal genotype was HPA-1bb and the paternal genotype was HPA-1aa; thus, all children were affected. RESULTS PLT counts for each infant improved with the administration of random-donor PLT transfusions. All three infants also received intravenous immunoglobulin. None had major bleeding. A small isolated subependymal hemorrhage was found incidentally in one infant; this remained stable on repeat imaging. CONCLUSIONS This is the first report of triplets with NAIT. Anti-HPA-1a is sufficiently potent to affect three infants simultaneously. Random-donor PLTs were effective in improving PLT counts in all three infants.

Abstract
Religious/spiritual (r/s) characteristics of physicians influence their attitude toward integrative medicine and spiritual care. Indonesia physicians collaborate with traditional, complementary, and alternative medicine (TCAM) professionals within modern healthcare system, while Indian physicians are not reported to do so. The aim of the study was to understand the r/s characteristics and their influence on Indian and Indonesian physicians' acceptance of TCAM/spirituality in modern healthcare system. An exploratory, pilot, cross-cultural, cross-sectional study, using Religion and Spirituality in Medicine, and Physician Perspectives (RSMPP) survey questionnaire, compared r/s characteristics and perspectives on integrative medicine of 169 physicians from two allopathic, Sweekar-Osmania University (Sweekar-OU), India, University of Airlanga (UNAIR), Indonesia, and a TCAM/Central Research Institute of Unani Medicine (CRIUM) institute from India. More physicians from UNAIR and CRIUM (89.1 %) described themselves as "very"/"moderately" religious, compared to 63.5 % Sweekar-OU (p = 0.0000). Greater number of (84.6 %) UNAIR physicians described themselves as "very" spiritual and also significantly high (p < 0.05) in intrinsic religiosity as compared to Sweekar-OU and TCAM physicians; 38.6 % of UNAIR and 32.6 % of CRIUM participants reported life-changing spiritual experiences in clinical settings as against 19.7 % of Sweekar-OU; 92.3 % of UNAIR, compared to CRIUM (78.3 %) and Sweekar-OU (62 %), felt comfortable attending to patients' spiritual needs, (p = 0.0001). Clinical comfort and not r/s characteristics of participants was the significant (p = 0.05) variable in full regression models, predictive of primary outcome criteria; "TCAM or r/s healing as complementary to allopathic treatment." In conclusion, mainstreaming TCAM into healthcare system may be an initial step toward both integrative medicine and also improving r/s care interventions by allopathic physicians.

Evaluation of robotic-assisted laparoscopic and open pyeloplasty in children: single-surgeon experience. Ann R Coll Surg Engl 2015; 97:109-14.

Abstract
INTRODUCTION Robotic-assisted laparoscopic pyeloplasty (RALP), the most commonly undertaken paediatric robotic urologic surgery, has not been compared against open pyeloplasty (OPN) by a single surgeon. Here, we describe our experience and outcomes. METHODS Children undergoing RALP or OPN from 2007 to 2013 were reviewed. Clinical success was defined as resolution of presenting symptoms and improved/stable hydronephrosis on ultrasound. RESULTS RALP and OPN cohorts comprised 52 and 40 patients, respectively. RALP patients were significantly older (6.8 vs 1.2 years, p<0.01) and heavier (28.4 vs 8.4 kg, p<0.01). Operative times for RALP were longer (203.3 vs 135.0 min, p<0.01), but decreased significantly with increasing experience (r(2)=0.42, p<0.01). Seven type-IIIb Clavien-Dindo complications occurred in RALP patients compared with two in OPN cases. There were no differences in postoperative narcotic administration (p=0.92) or duration of stay in hospital (DOSH) (p=0.93). A total of 11/40 (28%) OPN patients required epidural analgesia but none were placed in the RALP cohort. A total of 49/52 (94%) RALP patients and 40/40 OPN cases had successful outcomes. Three RALP patients required revision RALP. CONCLUSIONS These data show that outcomes for RALP and OPN were comparable. An initial learning curve with RALP is to be expected, but operative times for RALP approached those for OPN. Previously reported benefits of RALP (reduced analgesic requirements, DOSH) were not observed. This difference may have been due to comparison of a heterogeneous cohort. Close evaluation of complications allowed for improved placement of stents in RALP.
