ABSTRACT

OBJECTIVES: To determine the prevalence of eczema among children in New Zealand. METHODS: Population-based retrospective observational study utilising national pharmaceutical dispensing records for topical corticosteroids and emollients for all New Zealand children aged 0-14 years from 1st January 2006 to 31st December 2019. Data are reported using descriptive statistics, with comparisons between ethnicities and socioeconomic quintiles undertaken with rate ratios. RESULTS: Based on dispensing data, the prevalence of eczema for New Zealand children aged 0-14 years in 2018 was 14.0% (95% CI 14.0%-14.1%), with prevalence decreasing in older age groups (children aged <1 year 26.0% (25.6%-26.4%); children aged 10-14 years 8.8% (8.7%-8.9%)). Prevalence was higher in Pacific children (23.6% (23.3%-24.0%)), but slightly lower in Maori children (13.2% (13.0%-13.3%)). CONCLUSION: Eczema is a common condition affecting a considerable proportion of children in New Zealand. This study provides nationwide paediatric prevalence data for New Zealand, and highlights the increased burden of eczema in Pacific children. Inequity in dispensing of topical corticosteroids is postulated to explain the reduced rates found for Maori children compared to previous studies. These results support the need for further research to determine factors contributing to differing eczema prevalence rates in New Zealand.

ABSTRACT

In Maori and Pacific adults, the CREBRF rs373863828 minor (A) allele is associated with increased body mass index (BMI) but reduced incidence of type-2 and gestational diabetes mellitus. In this prospective cohort study of Maori and Pacific infants, nested within a nutritional intervention trial for pregnant women with obesity and without pregestational diabetes, we investigated whether the rs373863828 A allele is associated with differences in growth and body composition from birth to 12-18 months' corrected age. Infants with and without the variant allele were compared using generalised linear models adjusted for potential confounding by gestation length, sex, ethnicity and parity, and in a secondary analysis, additionally adjusted for gestational diabetes. Carriage of the rs373863828 A allele was not associated with altered growth and body composition from birth to 6 months. At 12-18 months, infants with the rs373863828 A allele had lower whole-body fat mass [FM 1.4 (0.7) vs. 1.7 (0.7) kg, aMD -0.4, 95% CI -0.7, 0.0, P = 0.05; FM index 2.2 (1.1) vs. 2.6 (1.0) kg/m2 aMD -0.6, 95% CI -1.2,0.0, P = 0.04]. However, this association was not significant after adjustment for gestational diabetes, suggesting that it may be mediated, at least in part, by the beneficial effect of CREBRF rs373863828 A allele on maternal glycemic status.

ABSTRACT

Background: Tobacco use significantly increases the rate of wound complications in patients undergoing total ankle arthroplasty (TAA). Preoperative optimization through smoking cessation programs significantly minimizes the rate of infection and improves wound healing in arthroplasty procedures. Despite its utility, minimal research has examined the cost-effectiveness of preoperative smoking cessation programs to reduce the need for extracapsular irrigation and debridement (I&D) due to wound complications following TAA. Methods: The cost of an I&D procedure was obtained from our institution's purchasing records. Baseline wound complication rates among tobacco users who have undergone TAA and smoking cessation program cost were obtained from literature. A break-even economic analysis was performed to determine the absolute risk reduction (ARR) to economically justify the implementation of preoperative smoking cessation programs. Different smoking cessation program and I&D costs were tested to account for variations in each factor. ARR was then used to calculate the number needed to treat (NNT) to prevent a single I&D while remaining cost-effective. Results: Smoking cessation programs were determined to be economically justified if it prevents 1 I&D surgery out of 8 TAAs among tobacco users (ARR = 12.66%) in the early postoperative period (<30 days). ARR was the same at the literature high (27.3%) and weighted literature average (13.3%) complication rates when using the cost of I&D surgery at our institution ($1757.13) and the literature value for a smoking cessation program ($222.45). Cost-effectiveness was maintained with higher I&D surgery costs and lower costs of smoking cessation treatment. Conclusion: Our model's input data suggest that the routine use of smoking cessation programs among tobacco users undergoing TAA is cost-effective for risk reduction of I&D surgery in the early postoperative period. This intervention was also found to be economically warranted with higher I&D costs and lower smoking cessation program costs than those found in the literature and at our institution.Level of Evidence: Level III, economic and decision analysis.

ABSTRACT

OBJECTIVE: To investigate associations of the Fetal Pillow® with maternal and neonatal morbidity. DESIGN: Retrospective cohort. SETTING: Two tertiary maternity units, New Zealand. POPULATION OR SAMPLE: Full dilatation singleton, term, cephalic caesarean section, with three comparisons: at Unit A (1) before versus after introduction of the Fetal Pillow® (1 Jaunary 2016-31 October 2021); (2) with versus without the Fetal Pillow® after introduction (27 July 2017-31 October 2021); and (3) between Unit A and Unit B during the same time period (1 January 2019-31 October 2021). The Fetal Pillow® is unavailable at Unit B. METHODS: Cases were ascertained and clinical data were extracted from electronic clinical databases and records. Outcome data were adjusted and presented as adjusted odds ratios (aOR) with 95% CI. MAIN OUTCOME MEASURES: Primary outcome "any" uterine incision extension; secondary outcomes included major extension (into adjacent structures), and a composite neonatal outcome. RESULTS: In all, 1703 caesareans were included; 375 with the device and 1328 without. Uterine incision extension rates were: at Unit A before versus after introduction: 26.8% versus 24.8% (aOR 0.88, 95% CI 0.65-1.19); at Unit A with the Fetal Pillow® versus without: 26.1% versus 23.8% (aOR 1.14, 95% CI 0.83-1.57); and at Unit A versus Unit B: 24.2% versus 29.2% (aOR 0.73, 95% CI 0.54-0.99). No differences were found in major extensions, or neonatal composite outcome. CONCLUSIONS: Despite the relatively large size of this study, it could not rule out either a positive or a negative association between use of the Fetal Pillow® and uterine extensions, major uterine incision extensions, and neonatal morbidity. Randomised controlled trial evidence is required to assess efficacy.

ABSTRACT

INTRODUCTION: Birth at early term (37+0-38+6 completed gestational weeks [GW] and additional days) is associated with adverse neonatal outcomes compared with waiting to ≥39 GW. Most studies report outcomes after elective cesarean section or a mix of all modes of births; it is unclear whether these adverse outcomes apply to early-term babies born after induction of labor (IOL). We aimed to determine, in women with a non-urgent induction indication (elective/planned >48 h in advance), if IOL at early and late term was associated with adverse neonatal and maternal outcomes compared with IOL at full term. MATERIAL AND METHODS: An observational cohort study as a secondary analysis of a multicenter randomized controlled trial of 1087 New Zealand women with a planned IOL ≥37+0 GW. Multivariable logistic regression was used to analyze neonatal and maternal outcomes in relation to gestational age; 37+0-38+6 (early term), 39+0-40+6 (full term) and ≥41+0 (late term) GW. Neonatal outcome analyses were adjusted for sex, birthweight, mode of birth and induction indication, and maternal outcome analyses for parity, age, body mass index and induction method. The primary neonatal outcome was admission to neonatal intensive care unit (NICU) for >4 hours; the primary maternal outcome was cesarean section. RESULTS: Among the 1087 participants, 266 had IOL at early term, 480 at full term, and 341 at late term. Babies born following IOL at early term had increased odds for NICU admission for >4 hours (adjusted odds ratio [aOR] 2.16, 95% confidence intervals (CI) 1.16-4.05), compared with full term. Women having IOL at early term had no difference in emergency cesarean rates but had an increased need for a second induction method (aOR 1.70, 95% CI 1.15-2.51) and spent 4 h longer from start of IOL to birth (Hodges-Lehmann estimator 4.10, 95% CI 1.33-6.95) compared with those with IOL at full term. CONCLUSIONS: IOL for a non-urgent indication at early term was associated with adverse neonatal and maternal outcomes and no benefits compared with IOL at full term. These findings support international guidelines to avoid IOL before 39 GW unless there is an evidence-based indication for earlier planned birth and will help inform women and clinicians in their decision-making about timing of IOL.

ABSTRACT

Joint arthroplasty of the first metatarsophalangeal (MTP) joint is an accepted surgical option for patients with hallux rigidus. However, this procedure has been reported to have a high complication rate and unpredictable survivorship. Implant arthroplasty failure is a devastating complication that results in significant osseous defect with altered biomechanics of the foot. Commonly, salvage options are limited to arthrodesis with bone grafting. However, outcomes are rarely reported. The purpose of this study is to investigate the fusion rates of first metatarsophalangeal joint arthrodesis after conversion from failed implant arthroplasty. A systematic review of electronic databases to find reports of conversion arthrodesis after failed implant arthroplasty was performed. Six studies involving a total of 76 patients with a weighted mean age of 54.9 met the inclusion criteria. Out of the 6 included articles, the nonunion rate was 16.5% at a weighted mean follow-up of 48.1 months. The nonunion rate in the current report is higher than reported nonunion rates of primary arthrodesis. More prospective studies with consistent and standard outcome measures are needed to further determine the success rate of this salvage procedure.Levels of Evidence: 4, Systematic Review of Level 4 Studies.

ABSTRACT

OBJECTIVE: We examined whether the risk of stillbirth was related to ambient air pollution in a UK population. DESIGN: Prospective case-control study. SETTING: Forty-one maternity units in the UK. POPULATION: Women who had a stillbirth ≥28 weeks' gestation (n = 238) and women with an ongoing pregnancy at the time of interview (n = 597). METHODS: Secondary analysis of data from the Midlands and North of England Stillbirth case-control study only including participants domiciled within 20 km of fixed air pollution monitoring stations. Pollution exposure was calculated using pollution climate modelling data for NO2 , NOx and PM2.5 . The association between air pollution exposure and stillbirth risk was assessed using multivariable logistic regression adjusting for household income, maternal body mass index (BMI), maternal smoking, Index of Multiple Deprivation quintile and household smoking and parity. MAIN OUTCOME MEASURE: Stillbirth. RESULTS: There was no association with whole pregnancy ambient air pollution exposure and stillbirth risk, but there was an association with preconceptual NO2 exposure (adjusted odds ratio [aOR] 1.06, 95% CI 1.01-1.08 per microg/m3 ). Risk of stillbirth was associated with maternal smoking (aOR 2.54, 95% CI 1.38-4.71), nulliparity (aOR 2.16, 95% CI 1.55-3.00), maternal BMI (aOR 1.05, 95% CI 1.01-1.08) and placental abnormalities (aOR 4.07, 95% CI 2.57-6.43). CONCLUSIONS: Levels of ambient air pollution exposure during pregnancy in the UK, all of were beneath recommended thresholds, are not associated with an increased risk of stillbirth. Periconceptual exposure to NO2 may be associated with increased risk but further work is required to investigate this association.

ABSTRACT

INTRODUCTION: Maternal perception of fetal movements during pregnancy are reassuring; however, the perception of a reduction in movements are concerning to women and known to be associated with increased odds of late stillbirth. Prior to full term, little evidence exists to provide guidelines on how to proceed unless there is an immediate risk to the fetus. Increased strength of movement is the most commonly reported perception of women through to full term, but perception of movement is also hypothesized to be influenced by fetal size. The study aimed to assess the pattern of maternal perception of strength and frequency of fetal movement by gestation and customized birthweight quartile in ongoing pregnancies. A further aim was to assess the association of stillbirth to perception of fetal movements stratified by customized birthweight quartile. MATERIAL AND METHODS: This analysis was an individual participant data meta-analyses of five case-control studies investigating factors associated with stillbirth. The dataset included 851 cases of women with late stillbirth (>28 weeks' gestation) and 2257 women with ongoing pregnancies who then had a liveborn infant. RESULTS: The frequency of prioritized fetal movement from 28 weeks' gestation showed a similar pattern for each quartile of birthweight with increased strength being the predominant perception of fetal movement through to full term. The odds of stillbirth associated with reduced fetal movements was increased in all quartiles of customized birthweight centiles but was notably greater in babies in the lowest two quartiles (Q1: adjusted OR: 9.34, 95% CI: 5.43, 16.06 and Q2: adjusted OR: 6.11, 95% CI: 3.11, 11.99). The decreased odds associated with increased strength of movement was present for all customized birthweight quartiles (adjusted OR range: 0.25-0.56). CONCLUSIONS: Increased strength of fetal movements in late pregnancy is a positive finding irrespective of fetal size. However, reduced fetal movements are associated with stillbirth, and more so when the fetus is small.

ABSTRACT

Fetal growth restriction (FGR) and maternal supine going-to-sleep position are both risk factors for late stillbirth. This study aimed to use magnetic resonance imaging (MRI) to quantify the effect of maternal supine position on maternal-placental and fetoplacental blood flow, placental oxygen transfer and fetal oxygenation in FGR and healthy pregnancies. Twelve women with FGR and 27 women with healthy pregnancies at 34-38 weeks' gestation underwent MRI in both left lateral and supine positions. Phase-contrast MRI and a functional MRI technique (DECIDE) were used to measure blood flow in the maternal internal iliac arteries (IIAs) and umbilical vein (UV), placental oxygen transfer (placental flux), fetal oxygen saturation (FO2 ), and fetal oxygen delivery (delivery flux). The presence of FGR, compared to healthy pregnancies, was associated with a 7.8% lower FO2 (P = 0.02), reduced placental flux, and reduced delivery flux. Maternal supine positioning caused a 3.8% reduction in FO2 (P = 0.001), and significant reductions in total IIA flow, placental flux, UV flow and delivery flux compared to maternal left lateral position. The effect of maternal supine position on fetal oxygen delivery was independent of FGR pregnancy, meaning that supine positioning has an additive effect of reducing fetal oxygenation further in women with FGR, compared to women with appropriately grown for age pregnancies. Meanwhile, the effect of maternal supine positioning on placental oxygen transfer was not independent of the effect of FGR. Therefore, growth-restricted fetuses, which are chronically hypoxaemic, experience a relatively greater decline in oxygen transfer when mothers lie supine in late gestation compared to appropriately growing fetuses. KEY POINTS: Fetal growth restriction (FGR) is the most common risk factor associated with stillbirth, and early recognition and timely delivery is vital to reduce this risk. Maternal supine going-to-sleep position is found to increase the risk of late stillbirth but when combined with having a FGR pregnancy, maternal supine position leads to 15 times greater odds of stillbirth compared to supine sleeping with appropriately grown for age (AGA) pregnancies. Using MRI, this study quantifies the chronic hypoxaemia experienced by growth-restricted fetuses due to 13.5% lower placental oxygen transfer and 26% lower fetal oxygen delivery compared to AGA fetuses. With maternal supine positioning, there is a 23% reduction in maternal-placental blood flow and a further 14% reduction in fetal oxygen delivery for both FGR and AGA pregnancies, but this effect is proportionally greater for growth-restricted fetuses. This knowledge emphasises the importance of avoiding supine positioning in late pregnancy, particularly for vulnerable FGR pregnancies.

ABSTRACT

First metatarsal phalangeal (MTP) joint arthrodesis has been employed for decades for pain related to arthritis and other associated abnormalities. Despite the commonality of the procedure there continues to be questions regarding functional expectations following the procedure especially when employed for correction of hallux valgus deformity. We surveyed 60 patients who had a tri plane MTP joint arthrodesis at mean 28.4 months (median 27.8) regarding their activities of daily living and sports activity through a direct conversation. Secondary endpoints assessed were return to activity, deformity correction and arthrodesis healing rate based on chart review and weightbearing radiographs. The primary outcomes showed robust return to all activities of daily living with 96.7% able to walk without restrictions and or pain, 98.3% were able to walk at a normal pace and 95% responded that loss of motion of their big toe did not affect their daily function. Regarding return to sports all patients that participated in sports before surgery resumed participation after with a trend toward increased sports activity. Early return to walking in a fracture boot was noted in this cohort at mean 4.1 days, return to athletic shoe at mean 6.3 weeks and full unrestricted activity at mean 13.3 weeks with no non-unions identified on radiographic or clinical exam. Deformity correction of the typical components of hallux valgus deformity was similar to previously published studies. This data set supports the hypothesis that patients undergoing first MTP joint arthrodesis can expect rapid and full return to activities of daily living and sports with a low complication rate.

ABSTRACT

Lapidus first tarsometatarsal (TMT) arthrodesis gained popularity for its ability to correct large deformities especially in cases of medial column instability. Despite solid first TMT fusion, instability between the first and second columns can result in loss of intermetatarsal (IM) angle correction over time. A "spot weld" or fusion between the first and second metatarsal may improve maintenance of correction. This retrospective study reviewed cases of Lapidus arthrodesis with first to second metatarsal base screw fixation for maintenance of IM correction and determine whether a "spot weld" is predictive of maintenance. A total of 90 cases (77 patients) performed by a single surgeon met inclusion with average follow-up of 309 days. First TMT fusion occurred in 87/90 (96.7%) cases with 76 dorsal plate, 10 dorsal staple, and 4 all screws. No incidence of complications related to the 1-2 screw was noted. Mean preoperative IM 1-2 angle 14.90°, mean correction to 6.22° post-operative and final maintained correction at 7.10°, mean loss of correction 0.87°. There were "spot welds" in 65/90 (72.2%) with mean loss of 0.48° versus loss of 1.88° in "no spot weld" subgroup (p < .001). Cases with no spot weld and screw lucency lost 2.25° (p < .001). Loss of IM 1-2 correction can occur due to first and second ray intra-column instability even in cases of solid first TMT arthrodesis. Incorporating a completed "spot weld" with bone grafting and first to second metatarsal screw was found to maintain correction with minimal loss (0.87°).

ABSTRACT

BACKGROUND: Approximately 1 in 4 pregnant women undergo induction of labor. Meta-analyses have shown that mechanical methods of induction of labor are safe and effective, as is starting induction in an outpatient setting. However, few studies have evaluated outpatient balloon catheter induction in comparison with pharmacologic methods. OBJECTIVE: This study aimed to determine whether women who underwent outpatient induction of labor with a balloon catheter would have a lower cesarean delivery rate than women who underwent inpatient induction of labor with vaginal prostaglandin E2 without an increase in adverse maternal or neonatal events. STUDY DESIGN: This was a superiority randomized controlled trial. The eligibility criteria were pregnant women (nullipara and multipara) with a live singleton fetus in vertex presentation with any medical comorbidity who underwent planned induction of labor at term and who had an initial modified Bishop Score of 0 to 6 at 1 of 11 public maternity hospitals in New Zealand. The intervention groups were outpatient single balloon catheter induction in comparison with inpatient vaginal prostaglandin E2 induction. The primary hypothesis was that participants who started their induction at home with a balloon catheter would have a lower risk for cesarean delivery than participants who started their induction with prostaglandins and remained in hospital throughout. The primary outcome was cesarean delivery rate. Participants were randomized using a centralized secure online randomization website in a 1:1 ratio, stratified by parity and hospital. The participants and outcome assessors were not blinded to group allocation. An intention-to-treat analysis with adjustment for stratification variables was used. RESULTS: A total of 539 participants were randomized to outpatient balloon catheter induction, and 548 participants were randomized to inpatient prostaglandin induction; the mode of birth was reported for all participants. The cesarean delivery rate was 41.0% among participants allocated to outpatient balloon induction and 35.2% among those allocated to inpatient prostaglandin induction (adjusted odds ratio, 1.27; 95% confidence interval, 0.98-1.65). Women in the outpatient balloon catheter group were more likely to have artificial rupture of membranes and to received oxytocin and an epidural. No differences were found in the rates of adverse maternal or neonatal events. CONCLUSION: Outpatient balloon catheter induction was not found to reduce the cesarean delivery rate when compared with inpatient vaginal prostaglandin E2 induction. The use of balloon catheters in an outpatient setting does not seem to increase the rate of adverse events for mothers or babies and can be offered routinely.

ABSTRACT

Vertical fixation through stemmed components has been a successful strategy in total ankle arthroplasty. Research in hip replacement surgery has demonstrated increased rates of stress shielding, aseptic loosening, thigh pain, and cystic formation around stemmed femoral implants extensively coated with porous surfaces. While some ankle prostheses have integrated porous coating technology with stemmed tibial implants, there is little to no research investigating the potential negative effects of bone bonding to the tibial stems and possible impact on tibial cyst formation. We performed a retrospective cohort study comparing the incidence of periprosthetic tibial cyst formation in smooth versus fully porous-coated stemmed tibial implants after undergoing total ankle implant arthroplasty. Radiographs were compared for postoperative rates of tibial cyst formation and bone bonding to the tibial stems. Relative risk for reoperation between the smooth and porous-coated implants was investigated. The smooth-stem group showed no incidence of tibial cyst formation nor signs of significant bone bonding to the tibial stems; however, the follow-up matched porous-coated group showed a rate of 63% of cystic formation with associated evidence of bone bonding on final radiographic follow-up (p < .01). Relative risk for reoperation was 0.74. Despite a higher incidence of tibial cyst formation in the stemmed ankle arthroplasty groups with porous coating, reoperation rates were similar. We theorize that the proximal bonding to the porous stem surface could impact the distal stems and result in the observed increase in cyst formation.

ABSTRACT

OBJECTIVE: Identify independent and novel risk factors for late-preterm (28-36 weeks) and term (≥37 weeks) stillbirth and explore development of a risk-prediction model. DESIGN: Secondary analysis of an Individual Participant Data (IPD) meta-analysis investigating modifiable stillbirth risk factors. SETTING: An IPD database from five case-control studies in New Zealand, Australia, the UK and an international online study. POPULATION: Women with late-stillbirth (cases, n = 851), and ongoing singleton pregnancies from 28 weeks' gestation (controls, n = 2257). METHODS: Established and novel risk factors for late-preterm and term stillbirth underwent univariable and multivariable logistic regression modelling with multiple sensitivity analyses. Variables included maternal age, body mass index (BMI), parity, mental health, cigarette smoking, second-hand smoking, antenatal-care utilisation, and detailed fetal movement and sleep variables. MAIN OUTCOME MEASURES: Independent risk factors with adjusted odds ratios (aOR) for late-preterm and term stillbirth. RESULTS: After model building, 575 late-stillbirth cases and 1541 controls from three contributing case-control studies were included. Risk factor estimates from separate multivariable models of late-preterm and term stillbirth were compared. As these were similar, the final model combined all late-stillbirths. The single multivariable model confirmed established demographic risk factors, but additionally showed that fetal movement changes had both increased (decreased frequency) and reduced (hiccoughs, increasing strength, frequency or vigorous fetal movements) aOR of stillbirth. Poor antenatal-care utilisation increased risk while more-than-adequate care was protective. The area-under-the-curve was 0.84 (95% CI 0.82-0.86). CONCLUSIONS: Similarities in risk factors for late-preterm and term stillbirth suggest the same approach for risk-assessment can be applied. Detailed fetal movement assessment and inclusion of antenatal-care utilisation could be valuable in late-stillbirth risk assessment.

ABSTRACT

BACKGROUND: Presentations for decreased fetal movements comprise a significant proportion of acute antenatal assessments. Decreased fetal movements are associated with increased likelihood of adverse pregnancy outcomes including stillbirth. Consensus-based guidelines recommend pregnant women routinely receive information about fetal movements, but practice is inconsistent, and the information shared is frequently not evidence-based. There are also knowledge gaps about the assessment and management of fetal movement concerns. Women have indicated that they would like more accurate information about what to expect regarding fetal movements. DISCUSSION: Historically, fetal movement information has focussed on movement counts. This is problematic, as the number of fetal movements perceived varies widely between pregnant women, and no set number of movements has been established as a reliable indicator of fetal wellbeing. Of late, maternity care providers have also advised women to observe their baby's movement pattern, and promptly present if they notice a change. However, normal fetal movement patterns are rarely defined. Recently, a body of research has emerged relating to maternal perception of fetal movement features such as strength, presence of hiccups, and diurnal pattern as indicators of fetal wellbeing in addition to frequency. CONCLUSION: Sharing comprehensive and gestation-appropriate information about fetal movements may be more satisfying for women, empowering women to identify for themselves when their baby is doing well, and importantly when additional assessment is needed. We propose a conversational approach to fetal movement information sharing, focusing on fetal movement strength, frequency, circadian pattern, and changes with normal fetal development, tailored to the individual.

ABSTRACT

Background: Societal changes that occurred during the COVID-19 pandemic may have altered the epidemiology of ankle fractures. The aim of this study was to assess trends in emergency department visits for ankle fractures from 2019 to 2020 in the United States. Methods: The National Electronic Injury Surveillance System (NEISS) database is a sample of hospitals in the United States stratified and weighted based on emergency department (ED) size, which was used to generate national estimates (NEs). The NEISS database was queried for patients who sustained an ankle fracture. Patients before COVID-19 (BC) (July 2019-December 2019) were compared to those during COVID-19 (DC) (July 2020-December 2020). Results: This study assessed 3350 (NE: 131,672) patients. Of these, 1683 (NE: 67,292) patients presented BC and 1667 (NE: 64,380) DC, representing a 4% decrease. The rate of alcohol-related ankle fractures increased (1.9% BC vs 2.6% DC; P < .001). The fraction of ankle fractures at school (3% BC vs 0.7% DC; P < .001) and during sports (19% BC vs 14% DC; P < .001) decreased. ED visits for ankle fracture leading to hospitalization marginally increased (23% BC vs 24% DC). The top 3 ankle fracture causes during COVID-19 were stairs (NE: 18,026, 28%), floors (ie, falling on floor) (NE: 4635, 7.2%), and skateboards (NE: 2832, 4.40%). The 3 largest increases in ankle fracture causes during COVID-19 were skateboards (+2.80%), floors (+1.10%), and powered scooters (+0.80%). Conclusion: There was a decrease in ankle fractures during the COVID-19 pandemic compared to the year before. Alcohol-related fractures increased as did fractures resulting in hospitalization. Ankle fractures caused by skateboards, powered scooters, and mopeds increased during COVID-19, whereas fewer occurred in school or during sports, consistent with restrictions to group activities. These findings may aid in proper health care budgeting in times of national and global crises. Level of Evidence: Level III, retrospective comparative study.

ABSTRACT

Modifiable infant sleep and care practices are recognised as the most important factors parents and health practitioners can influence to reduce the risk of sleep-related infant mortality. Understanding caregiver awareness of, and perceptions relating to, public health messages and identifying trends in contemporary infant care practices are essential to appropriately inform and refine future infant safe sleep advice. This scoping review sought to examine the extent and nature of empirical literature concerning infant caregiver engagement with, and implementation of, safe sleep risk-reduction advice relating to Sudden Unexpected Deaths in Infancy (SUDI). Databases including PubMed, CINAHL, Scopus, Medline, EMBASE and Ovid were searched for relevant peer reviewed publications with publication dates set between January 2000-May 2021. A total of 137 articles met eligibility criteria. Review results map current infant sleeping and care practices that families adopt, primary infant caregivers' awareness of safe infant sleep advice and the challenges that families encounter implementing safe sleep recommendations when caring for their infant. Findings demonstrate a need for ongoing monitoring of infant sleep practices and family engagement with safe sleep advice so that potential disparities and population groups at greater risk can be identified, with focused support strategies applied.

ABSTRACT

BACKGROUND: Mortality from sudden unexpected death in infancy (SUDI) has declined dramatically since the 'Back to Sleep' campaign. Deaths now are more prevalent in those with socioeconomic disadvantage. The investigation of SUDI frequently identifies parents that have mental health or drug, alcohol and addiction problems. AIMS: To estimate the prevalence of maternal mental health and substance use disorders and assess the magnitude of their risk for SUDI. METHODS: We conducted a population-based cohort study using data from the Integrated Data Infrastructure (IDI), a large research database containing linked data from a range of government agencies. The study population was all live births and their mothers in New Zealand from 2000 to 2016. The exposures of interest were maternal mental health problems and maternal substance use disorders in the year prior to the birth. The outcome was deaths from SUDI. RESULTS: The total population was 1086 504 live births and of these 1078 811 (99.3%) were able to be linked to other data sets within the IDI. The prevalence of maternal mental health problems in the total population was 5.2% and substance use disorder was 0.7%. There were 42 deaths from SUDI (0.75/1000) that were exposed to maternal mental illness and 864 deaths (0.84/1000) that were not exposed (adjusted relative risk (aRR)=1.23, 95% CI 0.90 to 1.68). There were 21 deaths from SUDI (2.67/1000) that were exposed to maternal substance use disorders and 885 (0.83/1000) that were not exposed (aRR=1.82, 95% CI 1.17 to 2.83). CONCLUSIONS: Maternal substance use disorders, but not maternal mental health problems, in the year prior to the child's birth was associated with an increased risk of SUDI. However, the numbers that are affected are small and the effect size moderate. This group of women should receive additional SUDI prevention services and Safe Sleep advice.

ABSTRACT

OBJECTIVE: To examine the effects of infant sofa-sleeping, recent use by caregivers of alcohol, cannabis, and/or other drugs, and bed type and pillows, on the risk of sudden unexpected death in infancy (SUDI) in New Zealand. STUDY DESIGN: A nationwide prospective case-control study was implemented between March 2012 and February 2015. Data were collected during interviews with parents/caregivers. "Hazards" were defined as infant exposure to 1 or more of sofa-sleeping and recent use by caregivers of alcohol, cannabis, and other drugs. The interaction of hazards with tobacco smoking in pregnancy and bed sharing, including for very young infants, and the difference in risk for Maori and non-Maori infants, also were assessed. RESULTS: The study enrolled 132 cases and 258 controls. SUDI risk increased with infant sofa-sleeping (imputed aOR [IaOR] 24.22, 95% CI 1.65-356.40) and with hazards (IaOR 3.35, 95% CI 1.40-8.01). The SUDI risk from the combination of tobacco smoking in pregnancy and bed sharing (IaOR 29.0, 95% CI 10.10-83.33) increased with the addition of 1 or more hazards (IaOR 148.24, 95% CI 15.72-1398), and infants younger than 3 months appeared to be at greater risk (IaOR 450.61, 95% CI 26.84-7593.14). CONCLUSIONS: Tobacco smoking in pregnancy and bed sharing remain the greatest SUDI risks for infants and risk increases further in the presence of sofa-sleeping or recent caregiver use of alcohol and/or cannabis and other drugs. Continued implementation of effective, appropriate programs for smoking cessation, safe sleep, and supplying safe sleep beds is required to reduce New Zealand SUDI rates and SUDI disparity among Maori.
