Predicting seizure outcomes and functional outcomes after hemispherotomy: are we any better?

INTRODUCTION: Present study attempted to analyze seizure freedom and detailed functional outcomes after functional hemispherotomy and utility of hemispherotomy outcome prediction scale (HOPS) scores in predicting outcomes. METHODS: Patients who underwent functional hemispherotomy were analyzed for clinical presentation, neuroimaging, seizure outcomes, and functional outcomes. RESULTS: A total of 76 procedures were performed on 69 patients. Mean age at the surgery was 8 ± 6.1 years. Fourteen patients were < 2 years. Age of onset epilepsy of the cohort was 2.0 ± 3.3 years. All had severe catastrophic epilepsy with multiple daily seizures. All patients had motor deficits with 36 (52%) patients had contralateral dysfunctional hand. Perinatal stroke (49%) was most common substrate followed by cortical malformations (21.7%). Eight patients had contralateral imaging abnormalities. Fifty-nine (86.76%) patients remained seizure free (Engle 1a) at 41 + -20.9 months. HOPS scores were available for 53 patients and lowest seizure outcome was 71% for HOPS score of 4. Lower HOPS scores predicted better seizure outcomes. Cortical malformations operated earlier than 2 years predicted poor seizure outcomes (66.6%). Positive functional outcomes are recorded in 80% of patients with 78% reporting improvement from the pre-surgical level. Five (7.2%) patients underwent shunt surgery. One mortality recorded. CONCLUSIONS: Hemispherotomy has excellent seizure outcomes. Early surgery in cortical malformations appears to be predictor of poorer seizure outcomes. HOPS score is a good tool to predict the seizure outcomes. Hemispherotomy is perceived to improve the Cognitive and functional performance.

Trends in Procedural Closure of the Patent Ductus Arteriosus among Infants Born at 22 to 30 Weeks' Gestation.

OBJECTIVE: To describe recent trend in procedural closure of the patent ductus arteriosus (PDA) among premature infants and compare the clinical characteristics of infants receiving surgical vs transcatheter closure. STUDY DESIGN: We conducted a descriptive, retrospective cohort study of preterm infants born between 220/7 and 296/7 weeks' gestation from 2014 through 2021. Infants were identified from the Pediatrix Clinical Data Warehouse. We excluded infants with any major congenital anomaly. We identified all preterm infants with a PDA and all those who underwent procedural closure (surgical ligation or transcatheter occlusion) and compared changes over time using ANOVA for continuous variables and the Cochran-Armitage trend test to evaluate time-related changes in proportions. RESULTS: The study cohort included 64 580 infants, of whom 24 028 (37.2%) were diagnosed with a PDA. The number of infants receiving any procedural closure of the PDA decreased from 371 (4.4%) in 2014 to 144 (1.9%) in 2021. During the same period, number of surgical ligations decreased from 369 (4.36%) to 64 (0.84%), and the number of transcatheter occlusions increased from 2 (0.02%) to 80 (1.05% p for all < 0.001). The median age at time of surgical ligation increased from 25 days (10th and 90th percentile, 10, 61) to 31 days (10th and 90th percentile, 16, 66), and the median age of transcatheter occlusion decreased from 103 days (10th and 90th percentile, 32, 150) to 43 days (10th and 90th percentile, 22, 91). CONCLUSIONS: There was a decrease in surgical closure and an increase in transcatheter occlusion of the PDA in infants born at 22-30 weeks' gestation from 2014 to 2021. Despite the decline in overall procedural closure, the rate of transcatheter occlusion surpassed surgical ligation by 2021. Narrowing differences in the median age and weight at closure suggest increasing overlap in the types of infants who received each type of procedural closure.

Neonatal Intensive Care Unit Resource Use for Infants at 22 Weeks' Gestation in the US, 2008-2021.

Importance: During the past decade, clinical guidance about the provision of intensive care for infants born at 22 weeks' gestation has changed. The impact of these changes on neonatal intensive care unit (NICU) resource utilization is unknown. Objective: To characterize recent trends in NICU resource utilization for infants born at 22 weeks' gestation compared with other extremely preterm infants (≤28 weeks' gestation) and other NICU-admitted infants. Design, Setting, and Participants: This is a serial cross-sectional study of 137 continuously participating NICUs in 29 US states from January 1, 2008, through December 31, 2021. Participants included infants admitted to the NICU. Data analysis was performed from October 2022 to August 2023. Exposures: Year and gestational age at birth. Main Outcomes and Measures: Measures of resource utilization included NICU admissions, NICU bed-days, and ventilator-days. Results: Of 825 112 infants admitted from 2008 to 2021, 60 944 were extremely preterm and 872 (466 [53.4%] male; 18 [2.1%] Asian; 318 [36.5%] Black non-Hispanic; 218 [25.0%] Hispanic; 232 [26.6%] White non-Hispanic; 86 [9.8%] other or unknown) were born at 22 weeks' gestation. NICU admissions at 22 weeks' gestation increased by 388%, from 5.7 per 1000 extremely preterm admissions in 2008 to 2009 to 27.8 per 1000 extremely preterm admissions in 2020 to 2021. The number of NICU admissions remained stable before the publication of updated clinical guidance in 2014 to 2016 and substantially increased thereafter. During the study period, bed-days for infants born at 22 weeks increased by 732%, from 2.5 per 1000 to 20.8 per 1000 extremely preterm NICU bed-days; ventilator-days increased by 946%, from 5.0 per 1000 to 52.3 per 1000 extremely preterm ventilator-days. The proportion of NICUs admitting infants born at 22 weeks increased from 22.6% to 45.3%. Increases in NICU resource utilization during the period were also observed for infants born at less than 22 and at 23 weeks but not for other gestational ages. In 2020 to 2021, infants born at less than or equal to 23 weeks' gestation comprised 1 in 117 NICU admissions, 1 in 34 of all NICU bed-days, and 1 in 6 of all ventilator-days. Conclusions and Relevance: In this serial cross-sectional study of 137 US NICUs from 2008 to 2021, an increasing share of resources in US NICUs was allocated to infants born at 22 weeks' gestation, corresponding with changes in national clinical guidance.

Esophageal Perforation of a Neonate Following Placement of an Oral Gastric Tube.

We present a case of neonatal esophageal perforation following routine oral gastric (OG) tube placement in the neonatal intensive care unit. This is a rare complication primarily affecting premature infants and can have significant morbidity and mortality. This case demonstrates the initial radiographic presentation of esophageal perforation and the subsequent imaging to confirm the diagnosis. Clinical management of this condition in the neonatal patient is also discussed. A unique highlight of this case is the difference in radiographic presentation on the initial study as compared to the later study.

Initial resuscitation of a neonate with congenital maxillomandibular syngnathia: A case report and literature review.

We report a full-term male neonate found to have undiagnosed syngnathia requiring extensive resuscitation at birth followed by urgent tracheostomy. We conducted a systematic literature review to study the presentation, resuscitation methods, and outcomes of neonates with congenital syngnathia. Of the 174 cases reported to date, 91 had initial resuscitation data available. Extensive resuscitation was required in 16 of these 91 infants (18%). This ranged from nasal intubation to emergent tracheostomy. These neonates are potentially higher risk deliveries for which methods in addition to those recommended by the American Heart Association neonatal resuscitation guidelines may be needed.

Intensive care resources required to care for critically ill children with focal intracranial infections.

The authors reviewed cases in which children with a focal infection inside the head (ex: a brain abscess) were cared for in their pediatric ICU to describe the frequency of complications and quantify the ICU resources needed (ex: breathing tube, blood pressure medications, and/or an intracranial pressure monitor). This information helps clarify illness severity and has identified complications that we should further investigate to improve care for these children.

A prospective, randomized, double blind, placebo-controlled evaluation of the effects of eicosapentaenoic acid and docosahexaenoic acid on the clinical signs and erythrocyte membrane polyunsaturated fatty acid concentrations in dogs with osteoarthritis.

BACKGROUND: Osteoarthritis (OA) in dogs is a prevalent and serious condition. The most common treatment for the clinical signs of OA in dogs is the administration of nonsteroidal antiiflammatory pharmaceuticals. Omega-3 (n-3) fatty acids have been shown to reduce the clinical signs of osteoarthritis in dogs. OBJECTIVE: The primary goals of this study were 1) to determine the effects of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) on the clinical signs of OA in dogs, 2) to evaluate the effects of supplementation on the arachadonic acid (ARA)/ (EPA+DHA) algorithm and 3) to correlate alterations in the ARA/(EPA+DHA) with changes in the clinical signs of canine OA. METHODS: Seventy-eight client owned dogs were enrolled in a prospective, randomized, double-blind, placebo controlled clinical trial. Dogs were randomized to placebo oil or triglyceride n-3 oil (providing an average dose of 69mg EPA+DHA/kg/day). Orthopedic examinations and blood analyses were performed at baseline, day 42, and day 84. A single investigator confirmed a diagnosis of OA of the coxofemoral joints and/or stifle joints in all dogs. RESULTS: Seventy-four dogs completed the trial. All clinical outcomes for measuring discomfort, lameness, and joint severity at day 84 and all blood metrics at day 42 and day 84 significantly (p<0.05) improved compared with placebo. No major side effects were observed. CONCLUSION AND CLINICAL RELEVANCE: This study demonstrated that the daily supplementation of a dogs diet with EPA and DHA shifts the blood fatty acid concentrations correlating to relief of clinical signs associated with OA in dogs.

Effect of Oral Re-esterified Omega-3 Nutritional Supplementation on Dry Eyes.

PURPOSE: To assess the effect of oral re-esterified omega-3 fatty acids on tear osmolarity, matrix metalloproteinase-9 (MMP-9), tear break-up time (TBUT), Ocular Surface Disease Index (OSDI), fluorescein corneal staining, Schirmer score, meibomian gland dysfunction (MGD) stage and omega-3 index in subjects with dry eyes and confirmed MGD. METHODS: This was a multicenter, prospective, interventional, placebo-controlled, double-masked study. Subjects were randomized to receive 4 softgels containing a total of 1680 mg of eicosapentaenoic acid/560 mg of docosahexaenoic acid or a control of 3136 mg of linoleic acid, daily for 12 weeks. Subjects were measured at baseline, week 6, and week 12 for tear osmolarity, TBUT, OSDI, fluorescein corneal staining, and Schirmer test with anesthesia. MMP-9 testing and omega-3 index were done at baseline and at 12 weeks. RESULTS: One hundred five subjects completed the study. They were randomized to omega-3 (n = 54) and control group (n = 51). Statistically significant reduction in tear osmolarity was observed in the omega-3 group versus control group at week 6 (-16.8 ± 2.6 vs. -9.0 ± 2.7 mOsm/L, P = 0.042) and week 12 (-19.4 ± 2.7 vs. -8.3 ± 2.8 mOsm/L, P = 0.004). At 12 weeks, a statistically significant increase in omega-3 index levels (P < 0.001) and TBUT (3.5 ± 0.5 s vs. 1.2 ± 0.5 s, P = 0.002) was also observed. Omega-3 group experienced a significant reduction in MMP-9 positivity versus control group (67.9% vs. 35.0%, P = 0.024) and OSDI scores decreased significantly in omega-3 (-17.0 ± 2.6) versus control group (-5.0 ± 2.7, P = 0.002). CONCLUSIONS: Oral consumption of re-esterified omega-3 fatty acids is associated with statistically significant improvement in tear osmolarity, omega-3 index levels, TBUT, MMP-9, and OSDI symptom scores.
