Monitoring of the Healthy Neonatal Transition Period with Serial Lung Ultrasound.

Ultrasound has been used to observe lung aeration and fluid clearance during the neonatal transition period, but there is no consensus regarding the optimal timing of lung ultrasound. We aimed to monitor the trend of the serial lung ultrasound score (LUS) and extended LUS (eLUS) throughout the neonatal transition period (≤1, 2, 4, 8, 24, and 48 h after birth), assess any correlation to the clinical presentation (using the Silverman Andersen Respiratory Severity Score (RSS)), and determine the optimal time of the ultrasound. We found both LUS and eLUS decreased significantly after 2 h of life and had similar statistical differences among the serial time points. Although both scores had a positive, moderate correlation to the RSS overall (Pearson correlation 0.499 [p < 0.001] between LUS and RSS, 0.504 [p < 0.001] between eLUS and RSS), the correlation was poor within 1 h of life (Pearson correlation 0.15 [p = 0.389] between LUS and RSS, 0.099 [p = 0.573] between eLUS and RSS). For better clinical correlation, the first lung ultrasound for the neonate may be performed at 2 h of life. Further research is warranted to explore the clinical value and limitations of earlier (≤1 h of life) lung ultrasound examinations.

The impact of small-for-gestational-age Status on the outcomes in very-Low-birth-weight (VLBW) premature infants: a prospective cohort study in Taiwan.

Background: The impact of small-for-gestational-age (SGA) on very-low-birth-weight (VLBW) premature infants remains inconclusive. This study aimed to assess the effects of being born SGA status on the short-term and long-term outcomes in VLBW preterm infants. Methods: We conducted a population-based, prospective cohort study on VLBW preterm infants born in Taiwan between 2012 and 2017. Sociodemographic, neonatal, growth and neurological data at 2 years of corrected age were collected. A total of 4243 VLBW infants born at 24 through 32 completed weeks' gestation participated in this study, of whom 1,005 had SGA status defined as a birth weight <10th percentile of gestation, and 3,238 did not (the non-SGA group).We compared the risks of short-term outcomes (neonatal mortality and morbidities), long-term outcomes (growth status, including weight, height, and head circumference <10th percentile, and neurodevelopmental impairments at 2 years of age). Subgroup analysis was performed by stratification of gestation age (GA): GA 24-26, 27-29 and 30-32 weeks. Results: In the analysis of short-term outcomes, the SGA group had an increased risk of neonatal mortality [adjusted odds ratio (OR) = 2.66, 2.99, and 2.19, respectively] in all GA subgroups in comparison with the non-SGA group (p < 0.05). The SGA group had a significantly increased risk of bronchopulmonary dysplasia in GA 27-29 and 30-32 weeks (adjusted OR = 2.11 and 1.86, respectively). We also found that there was an increased risk of severe retinopathy of prematurity in GA 24-26 and 27-29 weeks in the SGA group compared with the non-SGA group (adjusted OR = 1.68 and 1.59, respectively).In the analysis of long-term outcomes, the SGA group had a significantly increased risk of NDI throughout all GA subgroups (adjusted = 1.94, 1.33, and 1.35, respectively) in comparison with the non-SGA group. The SGA groups also had an increased risk of growth status <10th percentile at 2 years of age (p < 0.05). Conclusions: SGA VLBW premature infants had higher risks of neonatal death, growth status <10th percentile, and NDI at 2 years of corrected age compared with the non- SGA premature infants. Prenatal surveillance, postnatal attention, and long- term follow-up are warranted to improve the outcomes of VLBW SGA premature infants.

The effect of patient volume on mortality and morbidity of extremely low birth weight infants in Taiwan.

BACKGROUND: To assess whether the number of extremely low birth weight (ELBW) infants treated annually in neonatal intensive care units (NICUs) in Taiwan affects the mortality and morbidity of this patient population. METHODS: This retrospective cohort study included preterm infants with ELBW (≤1000 g). NICUs were divided into three subgroups according to the annual admissions of ELBW infants (low, ≤10; medium, 11-25; and high, >25). Perinatal characteristics, mortality, and short-term morbidities were compared between groups. RESULTS: A total of 1945 ELBW infants from 17 NICUs were analyzed (low-volume, n = 263; medium-volume, n = 420; and high-volume, n = 1262). After risk adjustments, infants from NICUs with low patient volumes were at a higher risk of death. The risk-adjusted odds ratios (aOR) for mortality were 0.61 (95% CI, 0.43-0.86) in the high-volume NICUs and 0.65 (95% CI, 0.43-0.98) in medium-volume NICUs, compared with infants admitted to low-volume NICUs. Infants in medium-volume NICUs had the lowest incidence of prenatal steroid exposure (58.1%, P < 0.001) and were associated with the highest risk of necrotizing enterocolitis (aOR, 2.35 [95% CI, 1.48-3.72]), severe intraventricular hemorrhage (aOR, 1.55 [95% CI, 1.01-2.28]), and bronchopulmonary dysplasia (aOR, 1.61 [95% CI, 1.10-2.35]). However, survival without major morbidity did not differ between the groups. CONCLUSION: The mortality risk was higher among ELBW infants admitted to NICUs with a low annual patient volume. This may emphasize the importance of systematically referring patients from these vulnerable populations to appropriate care settings.

Risk Factors of Language Delay at Two Years of Corrected Age among Very-Low-Birth-Weight Preterm Infants: A Population-Based Study.

Language delays are often underestimated in very-low-birth-weight (VLBW) preterm infants. We aimed to identify the risk factors of language delay at two years of corrected age in this vulnerable population. VLBW infants, who were assessed at two years of corrected age using the Bayley Scale of Infant Development, third edition, were included using a population-based cohort database. Language delay was defined as mild to moderate if the composite score was between 70 and 85 and severe if the score was < 70. Multivariable logistic regression analysis was used to identify the perinatal risk factors associated with language delay. The study comprised 3797 VLBW preterm infants; 678 (18%) had a mild to moderate delay and 235 (6%) had a severe delay. After adjusting for confounding factors, low maternal education level, low maternal socioeconomic status, extremely low birth weight, male sex, and severe intraventricular hemorrhage (IVH) and/or cystic periventricular leukomalacia (PVL) were found to be significantly associated with both mild to moderate and severe delays. Resuscitation at delivery, necrotizing enterocolitis, and patent ductus arteriosus requiring ligation showed significant associations with severe delay. The strongest factors predicting both mild to moderate and severe language delays were the male sex and severe IVH and/or cystic PVL; thus, early targeted intervention is warranted in these populations.

Enteroviral Rhombencephalitis with Abducens Nerve Palsy and Cardio-Pulmonary Failure in a 2-Year-Old Boy.

Enterovirus infection is endemic in many areas, especially in Southeast Asia. Enterovirus infection with severe complications (EVSC) is life-threatening, and timely diagnosis and management are crucial for successful management. Here, we report on a 2-year-old boy with hand, foot, and mouth disease. Myoclonic jerks developed and left abducens nerve palsy followed. Brain magnetic resonance imaging (MRI) showed rhombencephalitis. Pulmonary edema and cardiopulmonary failure developed, and intravenous immunoglobulin and extracorporeal membrane oxygenation were administered. He had a tracheostomy with home ventilator use after 64 days of hospitalization. At a 5-year follow-up, his neurodevelopment was normal with complete recovery from the abducens nerve palsy. The progress of EVSC may be rapid and fulminant, and timely diagnosis is critical for patient prognosis and outcomes. The presence of abducens nerve palsy is an indicator of enteroviral rhombencephalitis, and immediate and appropriate management is suggested.

Subclinical Changes in Left Heart Structure and Function at Preschool Age in Very Low Birth Weight Preterm Infants.

Background: Survivors of preterm birth are at risk of long-term cardiovascular consequences. The objective of this prospective observational study was to assess left heart function at preschool age in preterm children with very low birth weight (VLBW). Methods: We recruited children aged 5-6 years from preterm infants and full-term children. All subjects underwent conventional echocardiography and speckle-tracking echocardiography. The results were compared between the preterm and term groups. Results: Eighty-seven VLBW preterm children and 29 term controls were included in the study. After adjusting for body surface area, the preterm group compared to the full-term group had significantly smaller left ventricular (LV) end-diastolic and end-systolic internal dimensions (31.2 vs. 33.5 mm, p = 0.048; and 20.0 vs. 21.6 mm, respectively; p = 0.024), lower LV end-diastolic and end-systolic volumes (38.8 vs. 46.3 mL, p = 0.024; and 12.8 vs. 15.6 mL, respectively; p = 0.008). Left atrial (LA) maximal and minimal volume were also significantly smaller in the preterm group (15.4 vs. 18.9 mL, p = 0.017; and 6.2 vs 7.5 mL, respectively; p = 0.018). LV global longitudinal strain (-21.4 vs. -23.2%, p < 0.0001) and systolic strain rate (-1.30 vs. -1.37 /s, p = 0.001) were significantly lower in the preterm group than in the term control group. LA longitudinal strain was decreased (43.9 vs. 52.8%, p < 0.0001) and left atrial stiffness index (0.17 vs. 0.14, p < 0.0001) was increased in preterm infants. However, all the measurements in both groups were within normal range. Conclusions: Subclinical changes of left heart structure and function were found in VLBW infants at preschool age. Additional long-term follow-ups of the cardiovascular outcomes are needed in this vulnerable population.

An 18-year retrospective study on the epidemiology of early-onset neonatal sepsis - emergence of uncommon pathogens.

BACKGROUND: Nationwide group B Streptococcus agalactiae (GBS) antepartum screening was instituted in Taiwan in 2012. The impact of the policy on early-onset sepsis (EOS) has not been evaluated. This study aimed to examine the impact of the policy on the incidence of neonatal EOS. METHODS: This was a retrospective study conducted at MacKay Children's Hospital. Patients with culture-proven neonatal EOS were enrolled and divided by birth year in relation to the implementation of GBS prevention policy: Epoch 1, 2001-2004 pre-GBS screening; Epoch 2, 2005-2011 elective GBS screening; and Epoch 3, 2012-2018 universal GBS screening. The pathogens and antimicrobial resistance patterns were reviewed and analyzed. The incidence was modeled using Poisson regression. RESULTS: A total of 128 neonates met the enrollment criteria. The observed incidence of EOS was 1.52‰. The incidence rates of EOS, GBS, and Escherichia coli (E. coli) sepsis were similar in Epoch 1 and Epoch 3. E. coli and non-Enterococcal group D Streptococcus (GDS) infection increased significantly in term infants, whereas the EOS-related mortality rate declined in preterm infants. Approximately 72% of the isolated E. coli were ampicillin-resistant, and the antimicrobial sensitivity remained unaltered during the studied period. CONCLUSIONS: The overall EOS incidence has not changed from 2001 to 2018. However, changes in the causative pathogens were observed in both term and preterm infants. Clinicians should be aware of this evolving epidemiology to provide prompt appropriate perinatal management.

Predictive Validity of the Bayley-III Cognitive Scores at 6 Months for Cognitive Outcomes at 24 Months in Very-Low-Birth-Weight Infants.

Purpose: To assess the predictive validity of the Bayley Scales of Infant and Toddler Development, Third Edition (Bayley-III) cognitive scores at 6 months of corrected age (CA) for cognitive outcomes at 24 months of CA in very-low-birth-weight (VLBW) infants and investigate the predictors of change in cognitive outcomes. Methods: We retrospectively evaluated VLBW children enrolled in the Taiwan Premature Infant Follow-up Network between 2010 and 2015 and completed the Bayley-III at CA of 6 and 24 months. The predictive validity of the cognitive performance at 6-month CA for the cognitive outcomes at 24-month CA was analyzed. The positive and negative predictive factors were also evaluated using logistic regression. Cut-off scores of <70 and <85 were used to identify lower functioning groups based on the Bayley-III definition. Results: A total of 2,972 VLBW children, born with a mean weight of 1116.4 ± 257.5 g and mean gestational age of 29.0 ± 2.8 weeks, were evaluated. A cognitive score of <70 at 6-month CA had a positive predictive value (PPV) of 27.4% (95% confidence interval [CI]: 19.2-35.7%) for a cognitive score of <70 at 24-month CA, while the negative predictive value (NPV) was 97.3% (95% CI: 96.7-97.9%). A cut-off score of 85 had a PPV of 33.6% (95% CI: 28.1-39.0%) and an NPV of 87.7% (95% CI: 86.4-88.9%). Abnormal muscle tone at 6 months was a risk factor for cognitive function decline at 24 months for both Bayley-III cognitive cut-off scores: scores of 70 (adjusted odds ratio [AOR]: 2.8; 95% CI: 1.5-5.5) and 85 (AOR: 2.6; 95% CI: 1.6-4.1). Lower maternal socioeconomic status was associated with a worsening of the cognitive function in infants at 24 months who scored ≥85 at 6 months (AOR: 1.6; 95% CI: 1.2-2.0). Conclusion: Subnormal Bayley-III cognitive scores at 6-month CA were not predictive of subnormal cognitive function at 24-month CA. In children with normal cognition during early infancy, abnormal muscle tone and lower maternal socioeconomic status may influence the cognitive developing process; this highlighted the importance of early identification of high risk infants and complete preterm infant-associated public health policies to promote an improved neurodevelopmental outcome.

Impact of inhaled corticosteroids on the neurodevelopmental outcomes in chronically ventilated extremely low birth weight preterm infants.

BACKGROUND: Few studies have assessed the long-term impact of inhaled corticosteroids (ICS) in preterm infants. This study evaluated the neurodevelopmental outcomes of chronically ventilated extremely low birth weight (ELBW) preterm infants exposed to ICS. METHODS: The medical records of ELBW preterm infants admitted to two tertiary-level neonatal intensive care units from 2008 to 2014 were reviewed. Infants intubated for more than 28 days were included. The neurodevelopmental outcomes were compared at 24 months corrected age, between those with ICS exposure (inhaled group, IH) and those without it (non-inhaled group, NIH), by using the Bayley-Scale-of-Infant-and-Toddler Development-III (BSID-III). RESULTS: Out of the 115 infants included, 64 had an ICS exposure. The incidence of the morbidities at the time of discharge, was comparable between the two groups, except for the duration of oxygen and mechanical ventilation dependence (IH 124.8 ± 40.3 days vs. NIH: 101.0 ± 28.6 days, p < 0.001 and IH 60.0 ± 25.8 days vs. NIH: 42.3 ± 14.2 days, p < 0.001, respectively). Multiple logistic regression analysis at 24 months corrected age revealed no significant differences in the BSID-III scores and in the incidence of cerebral palsy and neurodevelopmental impairment. CONCLUSION: The late ICS exposure was not associated with neurodevelopmental impairment at 24 months corrected age in chronically ventilated ELBW infants; however, it did not reduce the duration of their dependence on oxygen and mechanical ventilation.

Reduced Lung Function at Preschool Age in Survivors of Very Low Birth Weight Preterm Infants.

Background: Survivors of preterm birth are at risk of long-term respiratory consequences. The objective of this prospective study was to assess pulmonary function at preschool age of former very low birth weight (VLBW) preterm children. Methods: Lung function of children born preterm and term controls aged 5-6 years were assessed by spirometry. The results were converted to z-scores. A questionnaire regarding respiratory symptoms was completed. Associations to gestational age (GA), birth weight (BW), bronchopulmonary dysplasia (BPD), and perinatal factors were assessed. Results: In total, 85 VLBW preterm children and 29 term controls were studied. Of the preterm children, the mean GA was 28.6 ± 2.6 weeks and the mean BW was 1,047 ± 273 gm. Preterm children had significantly lower z-scores of forced expiratory volume in 1 s (FEV1), FEV1/forced vital capacity (FVC) ratio, and forced expiratory flow rate between 25-75% of FVC (FEF25-75), compared with term controls (-0.73 vs. 0.04, p = 0.002; -0.22 vs. 0.39, p = 0.003; -0.93 vs. 0.0, p < 0.001; respectively). Further segregation of the preterm group revealed significantly impaired FEV1, FEF25-75 in children at earlier gestation (≤ 28 weeks, n = 45), lighter at birth (≤ 1,000 g, n = 38), or with BPD (n = 55) compared with term controls (p < 0.05). There were significant negative relationships between the severity of BPD with FEV1, FVC, and FEF25-75 (p < 0.05). However, no correlation between lung function measurements and respiratory symptoms was found. Conclusions: VLBW preterm infants have reduced lung function at preschool age, especially among those with younger GA, lower BW, and BPD. Additional long-term follow-up of respiratory outcomes are needed for this vulnerable population.

One-Seventh of Patients with COVID-19 Had Olfactory and Gustatory Abnormalities as Their Initial Symptoms: A Systematic Review and Meta-Analysis.

Coronavirus disease 2019 (COVID-19) patients exhibited protean clinical manifestations. Olfactory and gustatory abnormalities (anosmia and ageusia) were observed in COVID-19 patients, but the reported prevalence varied. In this systematic review, the prevalence of olfactory and gustatory abnormalities (OGA) was evaluated in laboratory-confirmed COVID-19 patients. On 8 May 2020, 14,506 articles were screened, while 12 of them were enrolled. A total of 1739 COVID-19 patients were analyzed, with a wide range of prevalence observed (5.6-94%). The pooled prevalence was 48.5% with high heterogeneity (I2, 98.8%; p < 0.0001). In total, 15.5% had OGA as their first symptom (I2, 22.6%; p = 0.27) among the patients analyzed. Contradictory to COVID-19 negative controls, patients with COVID-19 had a higher risk of OGA (odds ratio, 5.3; I2, 66.5%; p = 0.03). In conclusion, approximately half of COVID-19 patients had OGA, and one-seventh of them had OGA as their initial symptoms. OGA were cardinal symptoms of COVID-19, which may serve as clues for early diagnosis. Diagnostic testing for SARS-CoV-2 was suggested in patients with OGA during the COVID-19 pandemic to ensure timely diagnosis and appropriate quarantine.

Comparisons and Refinements of Neonatal Oro-Tracheal Intubation Length Estimation Methods in Taiwanese Neonates.

Objective: This study aimed to evaluate the efficacy of Tochen's formula [TF, body weight (kg) plus 6 cm], nasal septum to ear tragus length (NTL) + 1 cm, and Neonatal Resuscitation Program gestational age (NRP-GA) and body weight (NRP-BW)-based intubation table in estimating the oro-tracheal intubation length, and to improve the estimation efficacy using anthropometric measurements in Taiwanese neonates. Study design: This was a prospective observational study conducted at a neonatal intensive care unit in Taipei, Taiwan. One hundred intubated neonates were enrolled. The estimated intubation depth was defined as being mid-tracheal concordant if it placed the endotracheal tip between the upper border of the first and the lower border of the second thoracic vertebra. A linear regression model was used to analyze the relationships between mid-tracheal depth and body weight (BW), NTL and gestational age (GA), and to revise the NRP intubation tables using our results. Results: Overall, 56% of the neonates were born at a GA ≤ 28 weeks and 48% had a BW ≤ 1,000 g. The overall mid-tracheal concordance rates for TF, NTL + 1 cm, NRP-GA, and NRP-BW estimations were 51.0, 57.0, 15.0, and 14.0%, and in the infants with a BW ≤ 1,000 g 56.3, 56.3, 8.3, and 8.3%, respectively. Our revisions of the NRP intubation tables based on the anthropometric measurements of our participants improved the efficacy of BW, GA, and NTL estimations to 63, 44, and 61%, respectively. Conclusion: TF and NTL + 1 cm were more reliable than NRP intubation tables in predicting the neonatal mid-tracheal length in neonates of all BW and GA. Considering morphological differences secondary to ethnicity, we recommend using these tailored recommendations during neonatal resuscitation in Asian neonates.

Impact of Wearing Masks, Hand Hygiene, and Social Distancing on Influenza, Enterovirus, and All-Cause Pneumonia During the Coronavirus Pandemic: Retrospective National Epidemiological Surveillance Study.

BACKGROUND: The coronavirus disease (COVID-19) pandemic is an important health crisis worldwide. Several strategies were implemented to combat COVID-19, including wearing masks, hand hygiene, and social distancing. The impact of these strategies on COVID-19 and other viral infections remains largely unclear. OBJECTIVE: We aim to investigate the impact of implemented infectious control strategies on the incidences of influenza, enterovirus infection, and all-cause pneumonia during the COVID-19 pandemic. METHODS: We utilized the electronic database of the Taiwan National Infectious Disease Statistics System and extracted incidences of COVID-19, influenza virus, enterovirus, and all-cause pneumonia. We compared the incidences of these diseases from week 45 of 2016 to week 21 of 2020 and performed linear regression analyses. RESULTS: The first case of COVID-19 in Taiwan was reported in late January 2020 (week 4). Infectious control strategies have been promoted since late January. The influenza virus usually peaks in winter and decreases around week 14. However, a significant decrease in influenza was observed after week 6 of 2020. Regression analyses produced the following results: 2017, R2=0.037; 2018, R2=0.021; 2019, R2=0.046; and 2020, R2=0.599. A dramatic decrease in all-cause pneumonia was also reported (R2 values for 2017-2020 were 0.435, 0.098, 0.352, and 0.82, respectively). Enterovirus had increased by week 18 in 2017-2019, but this was not observed in 2020. CONCLUSIONS: Using this national epidemiological database, we found a significant decrease in cases of influenza, enterovirus, and all-cause pneumonia during the COVID-19 pandemic. Wearing masks, hand hygiene, and social distancing may contribute not only to the prevention of COVID-19 but also to the decline of other respiratory infectious diseases. Further studies are warranted to elucidate the causal relationship.

Systemic Infection Caused by Malassezia pachydermatis in Infants: Case Series and Review of the Literature.

BACKGROUND: Malassezia pachydermatis is a rare cause of systemic infection in infants. METHODS: A total of 4 cases of M. pachydermatis fungemia that occurred in our neonatal intensive care unit over a 21-month period were reviewed, as well as 27 cases reported in the literature since 1988. RESULTS: The patients were preterm with multiple complications and had birth weights ranging from 490 to 810 g and gestational age between 23 and 26 weeks. All patients had received prophylactic fluconazole, broad-spectrum antibiotics and parenteral lipid supplements before fungemia onset, which occurred between the age of 7 and 28 days. Symptoms were nonspecific and thrombocytopenia was the primary laboratory finding. All patients received intravenous antifungal treatment and recovered from their infection. The 27 cases from review of the literature also indicated that the infected infants were extremely low birth weight (77.8%), with multiple underlying diseases (94.7%), receiving lipid-supplementation (100%) from a central vascular catheter. Most infants received antifungal treatment (73.1%) and catheter removal (73.1%) as the management. CONCLUSIONS: M. pachydermatis is a pathogenic agent that causes late onset sepsis in critically ill low birth weight infants with generally good outcomes. Targeted antifungal treatment as well as catheter removal appear to be key factors for infection management.

Value of prenatal diagnosis of meconium peritonitis: Comparison of outcomes of prenatal and postnatal diagnosis.

Advancements in diagnostic modalities have improved the diagnosis of meconium peritonitis (MP) both in utero and ex utero. This study aimed to determine the efficacy of prompt prenatal and postnatal diagnoses of MP on the postnatal outcomes of these patients.We conducted a retrospective chart review of neonates with MP admitted to the Mackay Memorial Hospital Systems from 2005 to 2016. The prenatal diagnoses, postnatal presentations, surgical indications, operative methods, types of MP, operative findings, associated anomalies, morbidities, patient outcomes, and survival rates were analyzed. Morbidities included postoperative adhesion ileus, bacteremia, and short bowel syndrome. We also performed subgroup analyses of the morbidity and survival rates of prenatally versus postnatally diagnosed patients, as well as inborn versus outborn neonates.Thirty-seven neonates with MP were enrolled. Of this number, 24 (64.9%) were diagnosed prenatally. Twenty-two (59.5%) were born preterm. The most common prenatal sonographic findings included fetal ascites followed by dilated bowel loops. Abdominal distention was the most frequent postnatal symptom. Thirty-four (91.9%) neonates underwent surgery, whereas 3 were managed conservatively. Volvulus of the gastrointestinal tract was the most frequent anatomic anomaly. The total morbidity and survival rates were 37.8% and 91.9%, respectively. The morbidity and survival rates did not differ significantly between prenatally and postnatally diagnosed patients (37.5% vs 33.3%, P = 1.00; 91.7% vs 92.3%, P = 1.00, respectively). Inborn and outborn patients did not differ in terms of morbidity and survival rates (27.3% vs 53.3%, P = .17; 100% vs 80.0%, P = .06, respectively).Although not statistically significant, inborn MP neonates had higher survival rates when compared with outborn MP neonates. Prompt postnatal management at tertiary centers seemed crucial.

Bilateral vocal fold immobility in a single tertiary hospital in northern Taiwan: A 23-year retrospective review.

To determine the natural history of patient with bilateral vocal fold immobility (BVFI), and to identify the factors or predictors associated with the tracheostomy and duration of cannulation for those who require tracheostomy.A retrospective review was carried out at a single tertiary referral center over a 23-year period of infants less than 1 year old who presented with BVFI. All information related to sex, etiology, gestational age at birth, vocal fold (VF) position at diagnosis, presence of concomitant airway disease, age at attainment of VF movement, age at decannulation, and current tracheostomy status were recorded to perform descriptive and comparative analyses.Forty-one patients were enrolled, and the tracheostomy rate was 80.5% (33/41). Those with a median VF position had a higher rate of tracheostomy in comparison with those with a paramedian VF position (P = .003). Among patients who underwent tracheostomy, 77.4% (24/31) were eventually decannulated. The median duration of cannulation was 4.4 years (range: 0.8 - 10.7 years). Those who were found to have attainment of VF movement at less than 1-year-old had a shorter duration of cannulation than others (mean: 1.9 years vs 5.2 years, P < .001). The mortality rate of those patients who received tracheostomy was 9.7% (3/31).Although a high tracheostomy rate was found in BVFI patients, most of them underwent decannulation. The earlier attainment of VF movement is achieved, the shorter duration of cannulation is required. This information is important for physicians while following up BVFI patients who have undergone tracheostomy.

The impact of advanced maternal age on the outcomes of very low birth weight preterm infants.

The association between advanced maternal age and neonatal outcomes remains controversial. This study attempted to determine the short-term and long-term outcomes of very low birth weight (VLBW, <1500 g) preterm infants, born to mothers of advanced age (≥35 years).In this retrospective cohort study, VLBW infants were divided into the advanced maternal age group and comparison group. We compared the pregnancy complications, demographic factors, short-term morbidities, and neurodevelopmental outcomes using the Bayley Scales of Infant Development-Third Edition, at 24 months of corrected age between the 2 groups.The study comprised of 536 VLBW infants born to 483 mothers. Mothers of advanced age had a significantly lower rate of primiparity compared to the comparison group (45.8% vs 65.2%, P < .001), and were more likely to have gestational diabetes (13.7% vs 5.5%, P = .002) and to undergo in vitro fertilization (IVF; 18.4% vs 9.9%, P = .01). No significant differences were found between the 2 groups in terms of short-term outcomes. At 2 years of corrected age, advanced maternal age was associated with a higher incidence of severe speech delay (11.3% vs 5.7%, P = .04), neurodevelopmental impairment (NDI; 28.8% vs 18.4%, P = .02), and adverse composite outcome (37.4% vs 27.3%, P = .02). However, the differences in NDI and composite adverse outcomes were not statistically significant between the groups after adjustments for potential confounders.Advanced maternal age was not associated with major morbidities and long-term NDI among VLBW preterm infants. The association between advanced maternal age and severe speech delay in the infant needs further investigation.

Factors That Influence Human Milk Feeding at Hospital Discharge for Preterm Infants in a Tertiary Neonatal Care Center in Taiwan.

Human milk is considered optimal nutrition for newborn infants, especially preterm infants, and it can lessen morbidity in this population. Human milk feeding at hospital discharge may encourage breastfeeding at home. This study evaluated the incidence and predictive factors of human milk feeding of preterm infants at discharge. It included all preterm infants with gestational age of less than 37 weeks who were admitted to the Mackay Memorial Hospital in Taiwan from January to December 2010 who survived to discharge. Infants were classified into a human milk group or a formula milk group. Gestational age, birth weight, length of hospital stay, maternal age, maternal educational status, and morbidity of prematurity were compared between the groups. Of the 290 preterm infants, 153 (52.8%) were being fed human milk at hospital discharge. Compared with the formula milk group, the human milk group had lower birth weights, younger gestational age, higher rates of ventilator use, and longer hospital stays. These differences were not statistically significant for very low-birth-weight (birth weight of <1500 g) infants (n = 66). Multivariate analysis indicated that 2 factors, longer hospital stay and neonatal intensive care unit admission, were associated with human milk feeding at hospital discharge. These findings highlight the need for encouraging and helping all mothers, even those with relatively mature and healthy infants, to provide human milk for their infants.

Economic Conditions May Contribute to Increased Violence toward Children: A Nationwide Population-Based Analysis of Pediatric Injuries in Taiwanese Emergency Departments.

Childhood injuries are unfortunately common. Analysis procedures may assist professionals who work with children with developing preventive measures for protecting children's wellness. This study explores the causes of pediatric injuries presenting to an emergency department in Taiwan. This nationwide, population-based study was conducted using data from the National Health Insurance Research Database of Taiwan (NHIRD). Patients aged <18 years were identified from approximately one million individuals listed in the NHIRD. We followed up with these patients for nine years and analyzed the causes of injuries requiring presentation to an emergency department. Variables of interest were age, sex, injury mechanisms, and temporal trends. A total of 274,028 children were identified in our study. Between 2001 and 2009, the leading causes of pediatric injuries treated in emergency departments were motor vehicle injuries, falls, and homicide. The overall incidence of injuries declined over the course of the study because of reductions in motor vehicle accidents and falls. The incidence of homicide increased during the study period, particularly between 2007 and 2009. A moderately inverse correlation between homicide rate and economic growth was observed (correlation coefficient: -0.613, p = 0.041). There was a general decline in pediatric injuries between 2001 and 2009. Public policy changes, including motorcycle helmet laws and increases in alcohol taxes, may have contributed to this decline. Unfortunately, the incidence of homicide increased over the course of the study. Ongoing financial crises may have contributed to this increase. Multidisciplinary efforts are required to reduce homicide and reinforce the importance of measures that protect children against violence.
