Subjective memory complaints predict poorer functional recovery during the first year following hip-fracture surgery among elderly adults.

OBJECTIVES: Subjective memory complaints (SMCs) in the elderly are associated with poor recovery in performing activities of daily living. This study was designed to examine SMCs and their association with recovery and health outcomes of older persons within 1 year following hospital discharge after hip-fracture surgery. METHODS: Data were collected between 2012 and 2015 from 194 hip-fractured elders in northern Taiwan. SMCs were assessed by the Prospective and Retrospective Memory Questionnaire. Recovery outcomes included self-care ability (activities of daily living [ADLs] and instrumental activities of daily living [IADLs]), physical function (range of motion and maximal muscle strength), cognitive function, delirium, depressive symptoms, and health-related quality of life (HRQoL). Outcomes were assessed before discharge and 1, 3, 6, and 12 months afterwards. Associations of SMCs with participants' recovery outcomes were examined by the generalized estimating equation approach. RESULTS: Participants with SMCs had significantly poorer recovery outcomes than those without SMCs. Additionally, the interaction term for time-by-SMC was significant on ADLs, IADLs, maximal strength of quadriceps muscles, maximal strength of hip abductor muscles, ankle dorsiflexion, and HRQoL, suggesting that negative associations with SMCs increased over time. Participants with SMCs were at significantly higher risk for cognitive impairment and delirium than those without SMCs. CONCLUSIONS: Participants with SMCs not only had worse recovery than those without SMCs, but their rate of recovery was also slower during the first year following hip-fracture surgery. Therefore, SMCs need to be assessed to identify patients at high risk for worse recovery outcomes following hip fracture.

Perinatal factors in patent ductus arteriosus in very low-birthweight infants.

BACKGROUND: The relationship between hemoglobin and patent ductus arteriosus (PDA) has not been discussed before. The aim of this study was to assess the influence of hemoglobin and perinatal factors on PDA in very low-birthweight (VLBW) infants. METHODS: Using data from the Premature Baby Foundation of Taiwan (PBFA), the characteristics, perinatal factors, and hemoglobin of VLBW infants with and without PDA and treatment were compared. RESULTS: Between January 2008 and December 2010, 89 VLBW infants were admitted to hospital. The overall survival rate was 87.6%. Twelve infants were excluded. Compared to those without PDA, the 34 infants with PDA received oral indomethacin or surgery, had smaller mean gestational age (GA; 27.93 ± 1.818 weeks, P = 0.000003), lower mean birthweight (BW; 1031 ± 259 g, P = 0.0001), significantly lower Apgar score at 5 min, more severe respiratory distress syndrome (RDS; grade 3 or 4), greater use of surfactants, and lower mean hemoglobin (P = 0.018) after birth than those without PDA. Compared to those with indomethacin, the seven infants with surgery had lower mean GA (26.43 ± 1.718 weeks, P = 0.011), significantly lower Apgar scores at 1 min, but higher platelet count (P = 0.002) after birth, and more red blood cell transfusions (P = 0.039). CONCLUSIONS: Smaller GA, lower BW, lower Apgar score at 5 min, more severe RDS, greater use of surfactants, and lower hemoglobin after birth place VLBW infants at greater risk of PDA. Proper prenatal care, and prevention of premature labor and delivery may be the most important preventative factors. The appropriate hemoglobin level for PDA closure requires further investigation.

Neonatal outcomes in infants conceived using assisted reproductive technologies: A single medical center cohort study.

BACKGROUND: A significant rise in the use of assisted reproductive technology (ART) has been observed, but concerns about its impact on neonatal outcomes have been considered. The aim of this retrospective cohort study is to determine the association between ART and the risk of neonatal complications and congenital anomalies within a recent time period. METHODS: This retrospective study enrolled infants born after 20 weeks of gestation at a tertiary hospital in Taiwan between January 2019 and December 2021. The study population was divided into two groups: (1) ART pregnancy group and (2) natural pregnancy group. Maternal and neonatal characteristics, pregnancy complications, and neonatal outcomes were compared between the two groups. Multivariate logistic regression was used to adjust for maternal characteristics, preexisting maternal conditions, pregnancy complications, delivery methods, and infant characteristics. RESULTS: This study enrolled 1770 infants comprising 289 in the ART pregnancy group and 1481 in the natural pregnancy group. The ART pregnancy group showed higher rates of multiple births, preterm births, low birth weights, and longer hospitalization periods. In the stratified analyses that were conducted on singleton births, no significant difference was observed. In the case of multiple births, lower rates of preterm birth, low birth weight, and respiratory support were observed in the ART pregnancy group. After adjusting for maternal and infant characteristics, ART was not considered a significant risk factor for adverse neonatal outcomes, including mortality, complications, and congenital anomalies. CONCLUSION: Although ART pregnancies were more likely to result in multiple births and furthermore adverse outcomes, ART itself was not associated with an increased risk of poor neonatal outcomes. By implementing measures to control the number of implanted embryos, ensuring appropriate prenatal screening, and providing comprehensive postnatal care, the risks associated with increased multiple pregnancies caused by ART may be reduced.

Risk factors for urinary tract infection in infants with unexplained hyperbilirubinemia: a single center case-control study.

Background: Urinary tract infection (UTI) is a potential cause of neonatal jaundice. Nevertheless, there remains a lack of consensus regarding appropriate screening practices for UTI in infants with hyperbilirubinemia. This study aimed to analyze a group of jaundiced infants to assess the prevalence of UTI, explore potential risk factors, and examine the impact of UTI on the course and severity of neonatal jaundice. Methods: This retrospective case-control study was conducted on 150 jaundiced infants (aged < 8 weeks) without a known etiology in the hyperbilirubinemia work-up. All subjects underwent phototherapy treatment and UTI screening by catheterization. They were then classified into UTI and non-UTI groups based on urine culture results, with a positive urine culture indicating the growth of ≥10,000 colony-forming units. The clinical characteristics and jaundice-related parameters of both groups were analyzed. Results: Among the 150 jaundiced patients, the prevalence of UTI was 29%. There was a significantly higher male predominance in the UTI group, and patients with UTI also had a significantly longer duration of hospitalization compared to those without UTI. Significant risk factors associated with UTI in jaundiced infants included male gender and a peak total bilirubin level higher than 18 mg/dl during hospitalization. The most common pathogens identified in urine culture were Escherichia coli (41.9%) and Enterococcus faecalis (30.2%). Conclusion: In cases of neonatal jaundice where the underlying cause is not evident, screening for UTI should be performed, particularly when associated risk factors or inadequate response to phototherapy is present.

Relationship between orofacial dysfunction and orofacial features, oral function, and eating performance among preschool children.

Background/purpose: Orofacial (OF) development is influenced by multiple factors. This study aimed to explore the relationship between OF dysfunction (OFD) and OF features, oral function, and eating performance among preschool children. Materials and methods: There were 243 preschool children and their parents who participated in this cross-sectional study. Participant demographic information and eating performance were obtained from questionnaires completed by their mothers. OF features and functions were assessed using oral examinations. OFD assessments were performed using Nordic Orofacial Test-Screening (NOT-S). Results: Approximately 80% of participants had at least one domain of NOT-S affected. The main OFD in a structured interview was chewing and swallowing (64.61%). Dysarthria (40.38%), weak bite force (53.85%), inability to effectively chew (45.19%), and taking longer than 30 min to eat meals (75.00%) were significantly more prevalent among participants with OFD than among those without OFD (all P < 0.05). Also, compared with participants born full-term, those born prematurely and who had OFD had higher rates of V-shaped dental arch (42.11%), high-arched palate (31.58%), small mouth opening capacity (7.89%), dysarthria (65.79%), preference to eating soft-textured food (42.11%), and weak cough strength (21.05%). Taking longer than 30 min to eat meals (adjusted odds ratio (AOR = 8.87, P < 0.001) and not effectively chewing food (AOR = 8.81, P < 0.001) were significantly associated with OFD. Conclusion: Chewing and swallowing and habits are common among preschool children and associated with OFD. OFD is associated with OF features, and presented in oral function and eating performance.

Characterization of young infants with fecal carriage of multidrug-resistant Escherichia coli in Southern Taiwan.

BACKGROUND: The accelerating prevalence of extended-spectrum ß-lactamase (ESBL)-producing and multidrug-resistance (MDR) Escherichia coli(E. coli) become a public health challenge worldwide. This study aimed to discuss the prevalence of drug-resistant E. coli colonization and analyze its risk factors and clinical characteristics among young infants in Southern Taiwan. METHODS: Stool samples were collected from young infants, aged less than three months, within three days of their hospitalization from September to December 2019 in a tertiary hospital. A questionnaire was designed for parents to complete. E. coli colonies were selected and analyzed for antimicrobial susceptibility. PCR-based multilocus sequence typing was to detect the presence of sequence type ST131 and blaCTX-M genes. RESULTS: Among 100 enrolled infants, 36% had fecal carriage of E. coli isolates, of which twenty nine (80.5%) were MDR, thirteen (36.1%) were ESBL-producing isolates and five (13.8%) and ten (27.7%) were ST131 and strains carrying CTX-M-14 gene, respectively. Compared to non-ST131 and non-CTX-M-14 gene carrier, isolates of ST131 and CTX-M-14 gene carrier showed a significantly higher resistance rate to cefixime, ceftriaxone, and gentamycin, with p value all <0.05. CONCLUSION: The prevalence of ESBL-producing and MDR E. coli fecal carriage were both high in young infants. The most common sequence type is ST131, of which all are strains carrying CTX-M-14. Further surveillance and investigation to control for the high prevalence of antimicrobial-resistant E. coli fecal carriage among infants in Taiwan are warranted.

Uropathogens and clinical manifestations of pyuria-negative urinary tract infections in young infants: A single center cross-sectional study.

BACKGROUND: Urine leukocyte count under microscopy is one of the most frequently used routine screening tests for urinary tract infection (UTI). Nevertheless, it is observed that pyuria is lacking in 10-25% of children with UTI. This study aims to determine the factors related to pyuria-negative UTI in young infants aged under four months old. METHOD: This retrospective cross-sectional study was conducted on 157 patients aged under 4 months old with UTI. All subjects had paired urinalysis and urine culture, which were collected via transurethral catheterization. According to the results of their urinalysis, the patients were then classified as UTI cases with pyuria and UTI cases without pyuria. The clinical characteristics and outcomes of both groups were analyzed. RESULT: Among the 157 UTI patients, the prevalence of pyuria-negative UTI was 44%. Significant risk factors associated with pyuria-negative UTI included non-E.coli pathogens, younger age, shorter duration of fever prior to hospital visit, lower white blood cell (WBC) count upon hospital visit, and absence of microscopic hematuria. CONCLUSIONS: We found that non-E.coli uropathogens were the strongest factor related to pyuria-negative UTI. The absence of pyuria cannot exclude the diagnosis of UTI in young infants, and it's reasonable to perform both urinalysis and urine culture as a part of the assessment of febrile or ill-looking young infants.

Influences of Cognitive Function and Depressive Symptoms on Pain Trajectories During the First Year Following Hip Fracture Surgery: A Prospective Cohort Study.

OBJECTIVES: The purposes of this study were to explore trajectories for patterns of postoperative pain intensity during the first year following hip fracture surgery and the relationships between pain trajectory groups, cognitive impairment, and depressive symptoms. DESIGN: A prospective cohort correlational study. SETTING AND PARTICIPANTS: A total of 325 patients aged 60 years or older who had received hip fracture surgery at a 3000-bed medical center in northern Taiwan from September 2012 to March 2020. METHODS: Data were collected before hospital discharge and at 1, 3, 6, and 12 months postdischarge. Pain intensity was measured using a numeric rating scale; cognitive function was measured with the Taiwan version of the Mini-Mental State Examination; and depressive symptoms were measured by the Geriatric Depression Scale-Short Form. Patients with similar postoperative pain trajectories were categorized into groups and compared with group-based trajectory modeling. Cognitive impairment and depressive symptoms associated with each group were identified by logistic regression. RESULTS: Three different pain trajectory groups were identified: drastic decline-minimum pain (47.7%), gentle decline-mild pain (45.5%), and slight decline-moderate pain (6.8%). Patients with cognitive impairment [odds ratio (OR) 11.01, 95% CI 2.99-10.51] and at risk for depression (OR 49.09, 95% CI 10.46-230.30) were more likely to be in the moderate pain group than the minimum pain group. Patients with cognitive impairment (OR 2.07, 95% CI 1.25-3.42) were more likely to be in the mild pain group than the minimum pain group. Patients at risk for depression (OR 9.68, 95% CI 3.16-29.63) were more likely to be in the moderate pain group than the mild pain group. CONCLUSIONS AND IMPLICATIONS: Identifying postoperative pain trajectories can provide insight into the most appropriate pain management for older persons following hip fracture surgery. Attention should focus on assessments for cognitive impairment and risk of depression to prevent persistent postoperative pain. Future studies of older patients with clinically diagnosed cognitive impairment and depression are suggested.

Effects of early aminophylline therapy on clinical outcomes in premature infants.

BACKGROUND: Aminophylline use and the association between clinical outcomes and therapy timing have been less investigated. The objective of this study was to determine the efficacy of early aminophylline use (within the first two days of life) in premature infants. METHOD: A retrospective observational cohort of infants weighing <1500 g and <30 weeks of gestational age at Kaohsiung Veterans General Hospital received aminophylline either within the first two days of life (EA, early aminophylline group), after the third day of life (LA, late aminophylline group), or without aminophylline during the first month of life (WA, without aminophylline group). Demographic data and neonatal clinical outcomes were compared among the three groups. RESULTS: This study included 89 preterm infants (EA = 33, LA = 38, WA = 18). The EA group had a lower incidence of bronchopulmonary dysplasia (BPD) than the WA group (adjusted odds ratio [aOR] = 8.86(1.56-59.32); P = 0.024). Although there was no significant difference in BPD incidence between the EA and LA groups (aOR = 2.66(0.51-13.81), P = 0.244), a trend remained. Birth body weight less than 1000 g was also a significant risk factor for BPD (aOR = 8.86(1.32-47.41), P = 0.014). The duration of mechanical ventilation was shorter in the infants in the EA group compared to the WA group (estimated beta = -11.344(-19.57-3.12); P = 0.008). CONCLUSION: Early aminophylline administration may be associated with a decreased incidence of BPD in preterm infants. However, the clinical benefits of aminophylline treatment require further investigation. In addition, a birth body weight of less than 1000 g was a crucial risk factor for BPD.

Pulmonary hemorrhage in very low-birthweight infants: risk factors and management.

BACKGROUND: Beginning 2007, the intratracheal route of epinephrine to end massive pulmonary hemorrhage (MPH) in very low-birthweight (VLBW) infants was modified at Kaohsiung Veterans General Hospital. The aim of the present study was to assess the change in outcomes for these infants, and to evaluate the risk factors of MPH. METHODS: Using the database of the Premature Baby Foundation of Taiwan, the mortality, risk factors and characteristics of VLBW infants with or without MPH were compared between 2000-2006 and 2007-2010. RESULTS: Between January 2000 and December 2010, 399 VLBW infants were admitted to Kaohsiung Veterans General Hospital. Mean birthweight (BW) was 1099.6 ± 272.7 g, and mean gestational age (GA) was 28.7 ± 2.9 weeks. The overall survival rate was 84.2%. Sixteen (4%) had MPH: 11 in the first group (2000-2006; 18.2% survival rate), and five in the second group (2007-2010; 80% survival rate; P= 0.0000002). Infants with MPH had lower mean BW (864.9 ± 301.4 g, P= 0.0004), smaller mean GA (26.1 ± 2.0 weeks, P= 0.0002), significantly lower Apgar scores at 1 and 5 min, higher severity of respiratory distress syndrome (RDS; grades 3 or 4), and greater use of surfactant than infants without MPH. They also had more intraventricular hemorrhage and higher mortality. CONCLUSIONS: Smaller GA, lower BW, lower Apgar scores at 1 and 5 min, severe RDS (grades 3 or 4), and use of surfactant place VLBW infants at greater risk of MPH. Proper prenatal care and preventing premature labor and delivery were the most important preventative factors. A quick, deep thrust of intratracheal epinephrine with a catheter may improve survival.

A nomogram for predicting the development of serious bacterial infections in febrile term neonates: A single medical center experience in Southern Taiwan.

BACKGROUND: Serious bacterial infections (SBIs) could lead to mortality or severe long-term sequelae in neonates and infants aged <3 months. Accordingly, the aim of this study was to develop a quantitative and accurate assessment tool for predicting the risk of SBIs in febrile neonates. METHODS: This retrospective study enrolled 131 febrile term neonates (aged <30 days) who were hospitalized at Kaohsiung Veterans General Hospital between January 2005 and December 2020. These neonates were classified into SBI and nonbacterial infection (NBI) groups on the basis of microbiological laboratory reports. The clinical characteristics and routine blood tests of both groups at the time of admission were analyzed. Stepwise logistic regression was applied to create and validate the nomogram for SBI prediction. RESULTS: Among the 131 febrile neonates, 38 and 93 developed SBIs and NBIs, respectively. At the time of admission, ill clinical appearance, serum myelocyte/metamyelocyte presence, C-reactive protein (CRP) > 2.5 mg/dL, and pyuria were associated with an increased risk of SBIs. Accordingly, these four factors were used to develop a nomogram for SBI prediction, which exhibited significantly high performance (area under curve = 0.848, p < 0.001) in predicting SBI risk. CONCLUSION: We developed a nomogram combining clinical appearance, serum myelocyte/metamyelocyte presence, CRP, and pyuria for predicting SBI risk in febrile neonates. This tool can assist clinicians in making early diagnoses and delivering the appropriate treatment.

Combined Effects of Cognitive Impairment and Nutritional Trajectories on Functional Recovery for Older Patients after Hip-Fracture Surgery.

OBJECTIVES: Malnutrition and cognitive impairment are associated with poor functional recovery in older adults following hip-fracture surgery. This study examined the combined effects of cognitive impairment and nutritional trajectories on postoperative functional recovery for older adults following hip-fracture surgery. DESIGN: Prospective longitudinal correlational study. SETTING AND PARTICIPANTS: This study recruited 350 older adults (≥60 years of age) who received hip-fracture surgery at a 3000-bed medical center in northern Taiwan from September 2012 to March 2020. METHODS: Participant data were collected over a 2-year period after surgery for nutritional and cognitive status and activities of daily living (ADLs). Participants were grouped by type of nutritional trajectory using group-based trajectory modeling. Generalized estimating equations analyzed associations between trajectory groups/cognitive status at discharge and performance of ADLs. RESULTS: Nutritional trajectories best fit a 3-group trajectory model: malnourished (19%), at-risk of malnutrition (40%), and well-nourished (41%). Nutritional status for the malnourished group declined from 12 months to 24 months following surgery; nutritional status remained stable for at-risk of malnutrition and well-nourished groups. Interactions for cognitive impairment-by-nutritional status were significant: the malnourished + intact cognition subgroup had significantly better ADLs than the malnourished + cognitive impairment subgroup (b = 27.1, 95% confidence interval = 14.0-40.2; P < .001). For at-risk of malnutrition and well-nourished groups, there were no significant differences between cognitive impairment and intact cognition in ADLs. These findings suggest that nutritional status may buffer the negative effect of cognitive impairment on ADLs. CONCLUSIONS AND IMPLICATIONS: Better nutritional status over time for older adults following hip fracture can protect against adverse influences of cognitive impairment on ADLs during postoperative recovery. Participants with malnutrition and cognitive impairment had the poorest ADLs. These findings suggest interventions tailored to improving nutritional status may improve recovery for older adults following hip-fracture surgery.

Rectovaginal Colonization With Pathogenic Escherichia coli During Pregnancy And Neonatal Outcomes.

PURPOSE: The role of pathogenic Escherichia coli colonization in asymptomatic pregnant women is not well understood. The purpose of this work was to determine the prevalence, antimicrobial susceptibility, and neonatal outcomes of pathogenic E. coli colonization in pregnant women. PATIENTS AND METHODS: A total of 137 women from southern Taiwan with singleton pregnancies were enrolled between March 2016 and June 2017. The women were prospectively screened for E. coli colonization in the rectovaginal region during prenatal examination. The exclusion criteria are twin pregnancy of the mother and major anomaly of the neonate. All E. coli isolates were identified as either pathogenic or commensal strains, and their susceptibility to various antimicrobials was investigated. Clinical data of the infants were retrieved from their medical records. RESULTS: Results showed that 35.8% of asymptomatic pregnant women had pathogenic E. coli colonization in the rectovaginal region. Neonates born to such mothers showed significant morbidities, including hospitalization (OR= 3.74, 95% CI= 1.18~11.87), hyperbilirubinemia (OR= 2.81, 95% CI= 1.24~6.38), and gastrointestinal symptoms (OR= 5.53, 95% CI= 1.39~21.94). Maternal colonization with pathogenic E. coli at rectoanal site was a risk factor for neonatal hyperbilirubinemia after Benjamini-Hochberg (BH) adjustment (52% vs 24%, adjusted P= 0.048). CONCLUSION: The prevalence of pathogenic E. coli colonization in Taiwanese asymptomatic pregnant women was high, and the neonates born to colonized mothers exhibited potential neonatal morbidities. Larger studies are necessary to confirm these findings.

A family caregiver-oriented discharge planning program for older stroke patients and their family caregivers.

AIMS: To test the effectiveness of a discharge planning program for dyads of older stroke survivors and their family caregivers in Taiwan. BACKGROUND: Family caregivers of stroke survivors often feel inadequately prepared to deal with the physical, cognitive and emotional needs of the stroke survivors. However, little information could be found on discharge planning programs for caregivers of stroke survivors in Asian families. DESIGN: A randomised experimental design was used to explore the effects of a discharge planning program for 158 dyads of older stroke patients and their family caregivers. METHODS: The control group (n = 86 dyads) received only routine hospital discharge planning services and the experimental group (n = 72 dyads) received routine hospital discharge planning services plus the caregiver-oriented discharge planning program. Outcome variables were measured at baseline, before discharge and one month after hospital discharge. Variables were measured by the Nurse Evaluation of Caregiver Preparation Scale, Preparedness for Caregiving Scale, Caregiver Discharge Needs Satisfaction Scale and Perception of Balance between Competing Needs Scale. RESULTS: Caregivers in the experimental group had significantly better nurse evaluation and self-evaluation of preparation after the program than before, and greater satisfaction of discharge needs one month after discharge than before discharge. Caregivers in the experimental group had significantly better nurse evaluations and self-evaluations of preparation and better satisfaction of discharge needs after the program compared with the control group. However, no significant difference was found between caregiver groups in perceived balance of competing needs. CONCLUSIONS: This discharge planning program benefited family caregivers of older stroke patients during the transition from hospitalisation to one month after discharge. RELEVANCE TO CLINICAL PRACTICE: This caregiver-oriented discharge planning program, with its emphasis on individualised health education and home visits following discharge may improve caregivers' preparation and the satisfaction of their needs during the discharge transition.

A potentially fatal complication during subclavian vein catheterization in an infant with congenital heart disease-puncture to pulmonary artery directly: a case report.

The most frequent and acute complications of subclavian vein catheterization are arterial puncture to the subclavian artery and pneumothorax. We report an arterial puncture directly to the pulmonary artery in infant during subclavian vein catheterization.

Multiple clinical manifestations and diagnostic challenges of incontinentia pigmenti--12 years' experience in 1 medical center.

BACKGROUND: Incontinentia pigmenti (IP) is a rare X-linked dominant disorder that involves ectodermal tissues of multiple systems. Previous reports are few in Taiwan. To contribute toward better understanding of IP, we describe and discuss the clinical features of cases that were diagnosed in a medical center during the past 12 years. METHODS: The medical records of all patients with IP between July 1995 and June 2007 were reviewed retrospectively. The demographics, physical findings, pathology reports, molecular study reports, eosinophil counts and outcome were recorded. RESULTS: A total of 4 patients, 3 female and 1 male neonate, who met the criteria for the diagnosis of IP were enrolled. Among these cases, 3 were not diagnosed with IP at initial presentation but were regarded to have infectious diseases. A definite family history of 3 consecutive generations was proved not only by clinical manifestations but also by molecular study in 1 patient. The patient also had retinal and vitreous body hemorrhage, which rapidly progressed to retinal detachment of the right eye in 2 months. Another patient presenting with stage III hyperpigmentation at birth had an extremely rare finding of left foot deformity. The male patient had unilateral and localized vesicular lesions over his left thigh. CONCLUSION: Diagnosis of IP is difficult in the neonatal period. Referral to experienced specialists is necessary. Multiple clinical characteristics of IP and rapid progression of ophthalmologic manifestations can be demonstrated through our study. Furthermore, 3 of the 4 cases in our study are the very first reports in Taiwan.

Maternal pregnancy-induced hypertension increases subsequent neonatal necrotizing enterocolitis risk: A nationwide population-based retrospective cohort study in Taiwan.

The utero-placental ischemia induced by pregnancy-induced hypertension (PIH) could lead to fetal hypoxia and proinflammatory cytokine release, which are associated with the development of neonatal necrotizing enterocolitis (NEC). However, a few studies have investigated the relationship between PIH and neonatal NEC and have produced controversial results. Therefore, we attempted to assess the relationship between PIH and the subsequent neonatal NEC risk and identify predictive risk factors.Patients with newly diagnosed PIH were recruited from the Taiwan National Health Insurance Research Database (NHIRD). For each participant, 4 age- and delivery-year-matched participants without PIH were randomly selected. A multivariable logistic regression was performed for the identification of the predictive risk factors for neonatal NEC.Among the 23.3 million individuals registered in the NHIRD, 29,013 patients with PIH and 116,052 matched controls were identified. For the multivariable analysis, maternal PIH was associated with an increased risk of subsequent neonatal NEC development (odds ratio [OR] 1.86, 95% confidence interval [CI] 1.08-3.21, P = .026). Furthermore, single parity (OR 2.06, 95% CI 1.12-3.77, P = .019), preterm birth (OR 5.97, 95% CI 3.49-10.20, P < .001), multiple gestations (OR 2.25, 95% CI 1.22-4.14, P = .010), and intrauterine growth restriction (IUGR) (OR 3.59, 95% CI 2.06-6.24, P < .001) were independent risk factors for the development of subsequent neonatal NEC.Maternal PIH increases the risk for developing neonatal NEC. Furthermore, primiparity, preterm birth, multiple gestations, and IUGR were independent risk factors for neonatal NEC.

Reappraisal of the prostaglandin E1 dose for early newborns with patent ductus arteriosus-dependent pulmonary circulation.

OBJECTIVES: The usual initial dose of prostaglandin E1 (PGE1) for ductal-dependent congenital heart disease (CHD) is 50-100 ng/kg/minute. The aim of this study was to review our experience of a low initial dose of PGE1 treatment in early newborns with congenital heart disease and patent ductus arteriosus (PDA)-dependent pulmonary flow. METHODS: We reviewed the clinical data of 33 newborns with CHD and PDA-dependent pulmonary circulation who were admitted from January 2005 to December 2010. Clinical parameters were collected, including, PGE1 dosage, oxygenation condition, vital signs, and other related clinical parameters during admission. Echocardiography was employed to assess the status of the PDA as clinically indicated. RESULTS: Thirty-three newborns, including 17 males and 16 females, with CHD and PDA-dependent pulmonary circulation were enrolled in the study. Their mean age was 2.9 ± 5.1 (within the range of 1-26) days with a median of 1.0 day. Among the 33 cases, 25 were diagnosed with pulmonary atresia and eight with critical pulmonary stenosis. Twenty-five of our patients were treated with the initial low-dosage regimen of 20.0 ± 7.4 ng/kg/minute in our neonatal intensive care unit. None of these 25 patients with had significant apnea necessitating intubation and none had hypotension, fever, convulsion or cortical hyperostosis. Three of the eight patients who were treated with high-dose PGE1 (39 ± 13.2 ng/kg/minute) before referral to our unit had apnea and intubation after PGE1 use. All patients had adequate PDA patency with a low maintenance dose of 10.5 ± 5.3 ng/kg/minute before operation under our protocol. CONCLUSION: In our experience, adequate PDA flows in early newborns with CHD and PDA-dependent pulmonary circulation could be achieved at a much lower dose than recommended in the literature. The lower dose of PGE1 also causes much fewer complications, such as apnea, fever, and hypotension. For early newborns with CHD and PDA-dependent pulmonary circulation, treatment with a lower initial dose of PGE1 of 20 ng/kg/minute and a maintenance dose of 10 ng/kg/minute is recommended.

Urinary tract infection in infants: a single-center clinical analysis in southern Taiwan.

BACKGROUND: This study summarized the epidemiology, etiology, and susceptibility of pathogens to antibiotics, and specific characteristics in infants aged less than 4 months diagnosed with urinary tract infection in the past decade in Taiwan. METHODS: The medical charts of patients aged less than 4 months admitted for urinary tract infection to Kaohsiung Veterans General Hospital between January 2001 and December 2009 were retrospectively reviewed. RESULTS: A total of 132 patients, with male predominance (68.9%), were enrolled. The top three pathogens were similar to those identified in previous studies in Taiwan. The most common pathogen, Escherichia coli (85.3%), was resistant to ampicillin (75.9%), followed by sulfamethoxazole/trimethoprim (31.7%), and cefazolin (28.5%). Dimercaptosuccinic acid (DMSA) renal scan revealed 34.5% positive findings, while the vesicoureteral reflux (VUR) rate was 37.8% by direct radionuclide voiding cystography and/or voiding cysto-urethrography. Positive DMSA findings significantly correlated with VUR (p<0.001) and higher C-reactive protein level (p<0.05). CONCLUSIONS: E coli was the most common pathogen in the present cohort, and the top three pathogens were similar to those found in general pediatric population in Taiwan. VUR was the most common genitourinary tract anomaly in this age group. Positive DMSA was well correlated with VUR and higher C-reactive protein level.

Hemopericardium from right atrial laceration in a newborn.

We report the case of a newborn who suffered right atrial laceration during delivery. To our knowledge, there has been no previous report of blunt injury causing right atrial laceration with hemopericardium complicated by cardiac tamponade in the perinatal period.
