Implementation and Outcomes of a Pilot Collaborative Surgical Hydrocele Training in Côte d'Ivoire.

Lymphatic filariasis (LF) is a neglected tropical disease that can cause hydrocele and its associated stigma, loss of economic productivity, and depression. Hydrocele surgery is an essential part of LF morbidity management but can be difficult for national programs to implement. To improve access to hydrocele surgeries in Côte d'Ivoire, we provided a WHO-certified surgical training for six surgical teams from five health districts in Côte d'Ivoire. We then evaluated the surgical outcomes and assessed the impact of hydrocele surgery on quality of life of hydrocelectomy patients. Preoperative and operative records were reviewed to describe baseline hydrocele characteristics and operative details. Postoperative interviews were conducted 4 to 6 months after surgical correction using a standardized questionnaire. Seventeen men underwent surgery during the training and were available for an interview at the 6-month visit. At the time of 6-month follow-up, 11/17 (64.7%) reported improvement in activities of daily living and reduction in difficulties with work, 8/17 (47.1%) reported an improved economic situation, 15/17 (88.2%) reported improved social interactions, and 15/16 (93.8%) reported improved sex life after surgical correction. Three patients (17.6%) had minor postoperative complications, but none required hospitalization. All 17 patients who were available for an interview were satisfied with their surgery. Surgical hydrocelectomy training in Côte d'Ivoire was well received and provided life-altering health improvements for participating patients across multiple domains of life. Support to scale up surgical capacity for this neglected problem is needed.

Does Growth Velocity Affect Associations between Birth Weight and Neurodevelopment for Infants Born Very Preterm?

OBJECTIVE: To determine how neonatal growth velocity affects the association between birth weight and neurodevelopmental outcomes in infants born preterm. STUDY DESIGN: This study is a secondary analysis of the Maternal Omega-3 Supplementation to Reduce Bronchopulmonary Dysplasia in Very Preterm Infants (MOBYDIck) randomized multicenter trial conducted in breastfed infants born at <29 weeks of gestation, whose mothers were supplemented with docosahexaenoic acid or placebo during the neonatal period. Neurodevelopmental outcomes were assessed at 18-22 months of corrected age using the Bayley-III cognitive and language composite scores. The role of neonatal growth velocity was assessed with causal mediation and linear regression models. Subgroup analyses were stratified by birth weight z-score categories (<25th, ≥25th-≤75th, and >75th percentiles). RESULTS: Neurodevelopmental outcomes were available for 379 children (mean gestational age, 26.7 ± 1.5 weeks). Growth velocity partially mediated the relationships between birth weight and cognitive (ß = -1.1; 95% CI, -2.2 to -0.02; P = .05) and language scores (ß = -2.1; 95% CI, -3.3 to -0.8; P = .002). An increase by 1 g/kg/day in growth velocity was associated with an increase by 1.1 point in the cognitive score (95% CI, -0.03 to 2.1; P = .06) and 1.9 point in the language score (95% CI, 0.7 to 3.1; P = .001), after adjustment for birth weight z-score. For children with birth weight <25th percentile, a 1 g/kg/day increase in growth velocity was associated with an increase by 3.3 points in the cognitive score (95% CI, 0.5 to 6.0; P = .02) and 4.1 points in the language score (95% CI, 1.3 to 7.0; P = .004). CONCLUSIONS: Postnatal growth velocity mediated the relationship between birth weight and neurodevelopmental performance, with larger effects for children with lower birth weight.

Maternal High-Dose DHA Supplementation and Neurodevelopment at 18-22 Months of Preterm Children.

OBJECTIVES: To determine whether maternal supplementation with high-dose docosahexaenoic acid (DHA) in breastfed, very preterm neonates improves neurodevelopmental outcomes at 18 to 22 months' corrected age (CA). METHODS: Planned follow-up of a randomized, double-blind, placebo-controlled, multicenter trial to compare neurodevelopmental outcomes in breastfed, preterm neonates born before 29 weeks' gestational age (GA). Lactating mothers were randomized to receive either DHA-rich algae oil or a placebo within 72 hours of delivery until 36 weeks' postmenstrual age. Neurodevelopmental outcomes were assessed with the Bayley Scales of Infant and Toddler Development third edition (Bayley-III) at 18 to 22 months' CA. Planned subgroup analyses were conducted for GA (<27 vs ≥27 weeks' gestation) and sex. RESULTS: Among the 528 children enrolled, 457 (86.6%) had outcomes available at 18 to 22 months' CA (DHA, N = 234, placebo, N = 223). The mean differences in Bayley-III between children in the DHA and placebo groups were -0.07 (95% confidence interval [CI] -3.23 to 3.10, P = .97) for cognitive score, 2.36 (95% CI -1.14 to 5.87, P = .19) for language score, and 1.10 (95% CI -2.01 to 4.20, P = .49) for motor score. The association between treatment and the Bayley-III language score was modified by GA at birth (interaction P = .07). Neonates born <27 weeks' gestation exposed to DHA performed better on the Bayley-III language score, compared with the placebo group (mean difference 5.06, 95% CI 0.08-10.03, P = .05). There was no interaction between treatment group and sex. CONCLUSIONS: Maternal DHA supplementation did not improve neurodevelopmental outcomes at 18 to 22 months' CA in breastfed, preterm neonates, but subgroup analyses suggested a potential benefit for language in preterm neonates born before 27 weeks' GA.

Use of SMOF lipid emulsion in very preterm infants does not affect the incidence of bronchopulmonary dysplasia-free survival.

BACKGROUND: We aim to assess whether the docosahexaenoic acid (DHA)-containing lipid emulsion (LE) SMOFlipid 20% (Fresenius Kabi Canada Ltd) is associated with bronchopulmonary dysplasia (BPD)-free survival at 36 weeks' postmenstrual age in very preterm infants. METHODS: This cohort study is nested in the MOBYDIck randomized clinical trial (NCT02371460), which investigated the effect of maternal DHA supplementation on BPD-free survival in breastfed very preterm infants born between 23 0/7 and 28 6/7 weeks' gestation in 16 Canadian neonatal intensive care units (2015-2018). Parenteral SMOF-LE was given to the infants according to the sites' routine care protocols. Relative risks (RRs) were estimated using a modified Poisson regression model with generalized estimating equations taking into account recruitment site, multiple birth, DHA supplementation, birth weight, sex, and gestational age. RESULTS: Among 528 infants (mean gestational age, 26.5 weeks [SD, 1.6]), 272 received SMOF-LE. Overall, 56.7% of the infants in the SMOF-LE group and 59.7% infants in the non-SMOF-LE group survived without BPD (adjusted RR, 0.94 [95% CI, 0.77-1.14]; P = 0.51). BPD rates were 39.3% in the SMOF-LE group vs 34.1% in the non-SMOF-LE group (adjusted RR, 1.10 [95% CI, 0.82-1.47]; P = 0.53). Severe BPD rates were 31.8% in the SMOF-LE group vs 28.8% in the non-SMOF-LE group (adjusted P = 0.59). Mortality was not significantly different between the SMOF-LE (6.7%) and non-SMOF-LE groups (9.5%; adjusted P = 0.40). CONCLUSION: In very preterm infants, intravenous DHA-containing SMOF-LE during the neonatal period was not associated with BPD-free survival.

Effect of Maternal Docosahexaenoic Acid Supplementation on Very Preterm Infant Growth: Secondary Outcome of a Randomized Clinical Trial.

INTRODUCTION: The aim of the study was to determine the effect of a maternal docosahexaenoic acid (DHA) supplementation during lactation, compared with a placebo, on the neonatal growth profile of breastfed very preterm infants. METHODS: Preterm infants' growth profile, growth velocity from birth to 36 weeks' postmenstrual age (PMA), and growth at 36 weeks' PMA were pre-specified secondary outcomes of a randomized placebo-controlled trial conducted in 16 Canadian neonatal intensive care units (2015-2018). Lactating mothers who delivered before 29 weeks' gestation were given 1.2 g of DHA daily or a placebo within 72 h of delivery and up to 36 weeks' PMA. Analyses were performed using a linear regression model with generalized estimating equations. RESULTS: 461 mothers and their 528 infants (DHA, N = 273; placebo, N = 255) were included with mean gestational age of 26.5 weeks (standard deviation [SD] = 1.6); 275 (52.1%) were males; mean birth weight was 895 g (SD = 240). DHA interaction with sex was significant on weight profile (interaction p < 0.001), weight velocity (interaction p = 0.05), and weight at 36 weeks' PMA (interaction p = 0.02). Females in the DHA group gained more weight compared to the placebo group (mean difference [MD], 52.6 g [95% confidence interval [CI]: 24.5-80.8], p < 0.001). Weight velocity was significantly higher in females of the DHA group (MD, 3.4 g/kg/day [95% CI: 0.6-6.2], p = 0.02). At 36 weeks' PMA, the weight of males in the DHA group was significantly smaller (MD, -88.9 g [95% CI: -166.2 to -11.6], p = 0.02). CONCLUSION: DHA positively affected female infants' neonatal weight profile and velocity and negatively affected male infants' weight at 36 weeks' PMA.
