Ductal ligation timing and neonatal outcomes: a 12-year bicentric comparison.

ABSTRACT: Patent ductus arteriosus (PDA) is common among extremely preterm infants. In selected cases, surgical PDA ligation may be required. The timing for PDA ligation may depend upon a variety of factors, with potential clinical implications. We aimed to investigate the impact of different surgical PDA managements on ligation timing and neonatal outcomes. Inborn infants < 32 weeks of gestation and < 1500 g admitted at two tertiary Neonatal Intensive Care Units that underwent PDA ligation between 2007 and 2018 were enrolled in this retrospective cohort study and split into the following groups based on their surgical management: on-site bedside PDA ligation (ONS) vs. referral to an off-site pediatric cardiac surgery (OFS). Neonatal characteristics, surgical timing, and clinical outcomes of the enrolled infants were compared between the groups. Multivariate analysis was performed to evaluate the impact of PDA ligation timing on significantly different outcomes. Seventy-eight neonates (ONS, n = 39; OFS, n = 39) were included. Infants in the ONS group underwent PDA ligation significantly earlier than those in the OFS group (median age 12 vs. 36 days, p < 0.001) with no increase in postoperative mortality and complications. The multivariate analysis revealed a significant association between PDA ligation timing, late-onset sepsis prevalence (OR 1.045, 0.032), and oxygen need at discharge (OR 1.037, p = 0.025).Conclusions: Compared with off-site surgery, on-site bedside ligation allows an earlier surgical closure of PDA, with no apparent increase in mortality or complications. Earlier PDA ligation may contribute to reduced rates of late-onset sepsis and post-discharge home oxygen therapy, with possible cost-benefit implications. What is known: • Ineffective or contraindicated pharmacological closure of a hemodynamically significant PDA may require a surgical ligation. • Available literature comparing the effect of early vs. late PDA ligation on the main neonatal morbidities has yield contrasting results. What is new: • The availability of a cardiac surgery service performing bedside PDA ligation allows an earlier intervention compared to patient referral to an off-site center, with no difference in postoperative mortality and complications compared to off-site surgery. • Earlier PDA ligation was associated with a lower prevalence of late-onset sepsis and of oxygen need at discharge, with possible cost-benefit implications.

Project description:Chyluria is a rare disease in which chylous is excreted in the urine. Currently, management of chyluria includes conservative treatments and surgical measures. This study aimed to report our experience in treating non-parasitic chyluria with retroperitoneal laparoscopic ligation of the renal lymphatic vessels. Data from 52 patients who underwent retroperitoneoscopic ligation of the renal lymphatic vessels for non-parasitic chyluria between December 2009 and May 2022 were reviewed. After general anesthesia, the patients were passively placed in the healthy lateral decubitus position and underwent three-port retroperitoneal laparoscopy. Detailed medical data, including demographic characteristics, intraoperative outcomes, postoperative data, and complications, were reviewed. Fifty-two patients received surgery treatment at our institution. The mean disease course was 89.3 months. The mean age was 58.8 years, with females accounting for 57.7% (30/52); the majority of patients (33/52) had the laterality of chyluria on the left and 9 (17.3%) had a history of previous thoracic or abdominal surgery. Compared with the urine and blood data before the operation and on the first day after the operation, urinary protein, urinary tract infection, urinary red blood cells, hemoglobin, albumin, and serum total protein significantly improved 3 months after the operation. However, there were no significant differences in blood creatinine and blood urea nitrogen levels among the three groups. The mean surgery time was about 110.0 minutes, and the estimated total blood loss was 81.2 mL. The postoperative drainage volume was 229.9 mL. The average time to start a liquid diet and to be out of bed were 1.5 and 1.9 days, respectively. Transient postoperative gross hematuria occurred in eight patients, and complications occurred in five patients after surgery. The mean length of hospitalization was 6.6 days. The follow-up duration ranged from 3 to 152 months, and except for three patients who did not respond to treatment, the remaining patients had no recurrence and did not require reoperation. Our long-term follow-up results showed that renal pedicle lymphatic ligation via retroperitoneal laparoscopic surgery is an effective, safe, and reliable surgical option for patients with non-parasitic chyluria.

Project description:BackgroundPolicies for timing of cord clamping vary, with early cord clamping generally carried out in the first 60 seconds after birth, whereas later cord clamping usually involves clamping the umbilical cord more than one minute after the birth or when cord pulsation has ceased. The benefits and potential harms of each policy are debated.ObjectivesTo determine the effects of early cord clamping compared with late cord clamping after birth on maternal and neonatal outcomesSearch methodsWe searched the Cochrane Pregnancy and Childbirth Group's Trials Register (13 February 2013).Selection criteriaRandomised controlled trials comparing early and late cord clamping.Data collection and analysisTwo review authors independently assessed trial eligibility and quality and extracted data.Main resultsWe included 15 trials involving a total of 3911 women and infant pairs. We judged the trials to have an overall moderate risk of bias. Maternal outcomes: No studies in this review reported on maternal death or on severe maternal morbidity. There were no significant differences between early versus late cord clamping groups for the primary outcome of severe postpartum haemorrhage (risk ratio (RR) 1.04, 95% confidence interval (CI) 0.65 to 1.65; five trials with data for 2066 women with a late clamping event rate (LCER) of ~3.5%, I(2) 0%) or for postpartum haemorrhage of 500 mL or more (RR 1.17 95% CI 0.94 to 1.44; five trials, 2260 women with a LCER of ~12%, I(2) 0%). There were no significant differences between subgroups depending on the use of uterotonic drugs. Mean blood loss was reported in only two trials with data for 1345 women, with no significant differences seen between groups; or for maternal haemoglobin values (mean difference (MD) -0.12 g/dL; 95% CI -0.30 to 0.06, I(2) 0%) at 24 to 72 hours after the birth in three trials. Neonatal outcomes: There were no significant differences between early and late clamping for the primary outcome of neonatal mortality (RR 0.37, 95% CI 0.04 to 3.41, two trials, 381 infants with a LCER of ~1%), or for most other neonatal morbidity outcomes, such as Apgar score less than seven at five minutes or admission to the special care nursery or neonatal intensive care unit. Mean birthweight was significantly higher in the late, compared with early, cord clamping (101 g increase 95% CI 45 to 157, random-effects model, 12 trials, 3139 infants, I(2) 62%). Fewer infants in the early cord clamping group required phototherapy for jaundice than in the late cord clamping group (RR 0.62, 95% CI 0.41 to 0.96, data from seven trials, 2324 infants with a LCER of 4.36%, I(2) 0%). Haemoglobin concentration in infants at 24 to 48 hours was significantly lower in the early cord clamping group (MD -1.49 g/dL, 95% CI -1.78 to -1.21; 884 infants, I(2) 59%). This difference in haemoglobin concentration was not seen at subsequent assessments. However, improvement in iron stores appeared to persist, with infants in the early cord clamping over twice as likely to be iron deficient at three to six months compared with infants whose cord clamping was delayed (RR 2.65 95% CI 1.04 to 6.73, five trials, 1152 infants, I(2) 82%). In the only trial to report longer-term neurodevelopmental outcomes so far, no overall differences between early and late clamping were seen for Ages and Stages Questionnaire scores.Authors' conclusionsA more liberal approach to delaying clamping of the umbilical cord in healthy term infants appears to be warranted, particularly in light of growing evidence that delayed cord clamping increases early haemoglobin concentrations and iron stores in infants. Delayed cord clamping is likely to be beneficial as long as access to treatment for jaundice requiring phototherapy is available.

Project description:ObjectiveThis study aimed to profile the cytokine/chemokine response from day 0 to 7 in infants (≥36 weeks of gestational age) with neonatal encephalopathy (NE) and to explore the association with long-term outcomes.Study designThis was a secondary study of the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) Neonatal Research Network randomized controlled trial of whole body hypothermia for NE. Eligible infants with moderate-severe NE were randomized to cooling or normothermia. Blood spots were collected on days 0 to 1, 2 to 4, and 6 to 7. Twenty-four cytokines/chemokines were measured using a multiplex platform. Surviving infants underwent neurodevelopmental assessment at 6 to 7 years. Primary outcome was death or moderate-severe impairment defined by any of the following: intelligence quotient <70, moderate-severe cerebral palsy (CP), blindness, hearing impairment, or epilepsy.ResultsCytokine blood spots were collected from 109 participants. In total 99 of 109 (91%) were assessed at 6 to 7 years; 54 of 99 (55%) developed death/impairment. Neonates who died or were impaired had lower early regulated upon activation normal T cell expressed and secreted (RANTES) and higher day 7 monocyte chemotactic protein (MCP)-1 levels than neonates who survived without impairment. Though TNF-α levels had no association with death/impairment, higher day 0 to 1 levels were observed among neonates who died/developed CP. On multiple regression analysis adjusted for center, treatment group, sex, race, and level of hypoxic ischemic encephalopathy, higher RANTES was inversely associated with death/impairment (odds ratio (OR): 0.31, 95% confidence interval [CI]: 0.13-0.74), while day seven MCP-1 level was directly associated with death/impairment (OR: 3.70, 95% CI: 1.42-9.61). Targeted cytokine/chemokine levels demonstrated little variation with hypothermia treatment.ConclusionRANTES and MCP-1 levels in the first week of life may provide potential targets for future therapies among neonates with encephalopathy.Key points· Elevation of specific cytokines and chemokines in neonates with encephalopathy has been noted along with increased risk of neurodevelopmental impairment in infancy.. · Cytokine/chemokines at <7 days were assessed among neonates in a trial of hypothermia for HIE.. · Neonates who died or were impaired at 6 to 7 years following hypoxic-ischemic encephalopathy had lower RANTES and higher MCP-1 levels than those who survived without impairment..

Project description:ObjectiveThe current recommendations are to perform carotid endarterectomy within 2 weeks of symptoms for maximum long-term stroke prevention, although urgent carotid endarterectomy within 48 hours has been associated with increased perioperative stroke. With the development and rapid adoption of transcarotid artery revascularization (TCAR), we decided to study the effect of timing on the outcomes after TCAR.MethodsThe Vascular Quality Initiative database was searched for symptomatic patients who had undergone TCAR from September 2016 to November 2019. These patients were stratified by the interval to TCAR after symptom onset: urgent, within 48 hours; early, 3 to 14 days; and late, >14 days. The primary outcome was the in-hospital rate of combined stroke and death (stroke/death), evaluated using logistic regression analysis. The secondary outcome was the 1-year rate of recurrent ipsilateral stroke and mortality, evaluated using Kaplan-Meier survival analysis.ResultsA total of 2608 symptomatic patients who had undergone TCAR were included. The timing was urgent for 144 patients (5.52%), early for 928 patients (35.58%), and late for 1536 patients (58.90%). Patients undergoing urgent intervention had an increased risk of in-hospital stroke/death, which was driven primarily by an increased risk of stroke. No differences were seen for in-hospital death. On adjusted analysis, urgent intervention resulted in a threefold increased risk of stroke (odds ratio [OR], 2.8; 95% confidence interval [CI], 1.3-6.2; P = .01) and a threefold increased risk of stroke/death (OR, 2.9; 95% CI, 1.3-6.4; P = .01) compared with late intervention. Patients undergoing early intervention had comparable risks of stroke (OR, 1.3; 95% CI, 0.7-2.3; P = .40) and stroke/death (OR, 1.2; 95% CI, 0.7-2.1; P = .48) compared with late intervention. On subset analysis, the type of presenting symptoms was an effect modifier. Patients presenting with stroke and those presenting with transient ischemic attack or amaurosis fugax both had an increased risk of stroke/death when undergoing urgent compared with late TCAR (OR, 2.7; 95% CI, 1.1-6.6; P = .04; and OR, 4.1; 95% CI, 1.1-15.0; P = .03, respectively). However only patients presenting with transient ischemic attack or amaurosis fugax had experienced an increased risk of stroke with urgent compared with late TCAR (OR, 5.0; 95% CI, 1.4-17.5; P < .01). At 1 year of follow-up, no differences were seen in the incidence of recurrent ipsilateral stroke (urgent, 0.7%; early, 0.2%; late, 0.1%; P = .13) or postdischarge mortality (urgent, 0.7%; early, 1.6%; late, 1.8%; P = .71).ConclusionsWe found that TCAR had a reduced incidence of stroke when performed 48 hours after symptom onset. Urgent TCAR within 48 hours of the onset of stroke was associated with a threefold increased risk of in-hospital stroke/death, with no added benefit for ≤1 year after intervention. Further studies are needed on long-term outcomes of TCAR stratified by the timing of the procedure.
