Noninvasive Respiratory Support or Intubation during Stabilization after Birth and Neonatal and Neurodevelopmental Outcomes in Infants Born Preterm at 23-25 Weeks of Gestation.

Objective: To examine the association between noninvasive respiratory support (NRS) or tracheal intubation (TI) during stabilization in infants born at 23-25 weeks of gestation and severe brain injury (sBI) or death, and significant neurodevelopmental impairment (sNDI).

Study Design: A retrospective cohort study of infants born at 23°-25 weeks of gestation in Canada. We compared infants successfully managed with NRS or TI during 30 minutes after birth.

CPAP Versus NIPPV Postextubation in Preterm Neonates: A Comparative-Effectiveness Study.

Background And Objectives: Nasal intermittent positive pressure ventilation (NIPPV) has been shown to be superior to nasal continuous positive airway pressure (CPAP) postextubation in preterm neonates. However, studies have not permitted high CPAP pressures or rescue with other modes. We hypothesized that if CPAP pressures >8 cmH2O and rescue with other modes were permitted, CPAP would be noninferior to NIPPV.

Twenty-seven-gauge vitrectomy: a consecutive, single-centre case series with exclusive use over a 4-year period.

Background: To assess the safety and effectiveness of the exclusive use of 27-gauge instruments for all vitreoretinal diseases requiring vitrectomy.

Methods: In this retrospective study, 1020 consecutive surgeries were performed on 958 eyes of 848 patients using 27-gauge instruments from March 2017 to June 2021. Patients with a minimum follow-up of 3 months were included.

A prospective randomised controlled trial evaluating prophylactic Floseal, a gelatin and thrombin-based haemostatic matrix, in postoperative drain output and blood transfusion in transforaminal lumbar interbody fusion surgery.

Purpose: To evaluate the prophylactic use of Floseal in reducing postoperative blood loss in patients undergoing Transforaminal Lumbar Interbody Fusion (TLIF). TLIF is a lumbar spine decompression and fusion procedure with potential for postoperative blood loss. Prophylactic application of Floseal, a gelatin and thrombin-based haemostatic matrix to the surgical wound before closure was shown to be effective in reducing postoperative drain output in anterior cervical discectomy and fusion.

The Use of Five-Strand Hamstring Autograft to Increase the Graft Size in Anterior Cruciate Ligament Reconstruction-A Prospective Cohort Study With Satisfactory Early Clinical Results.

Objectives: To report on the outcomes of using 5-strand hamstring autograft to increase the graft size for anterior cruciate ligament (ACL) reconstruction and to determine whether the clinical results are comparable to using conventional 4-strand graft.

Methods: A prospective cohort study of patients with arthroscopic-assisted single-bundle ACL reconstruction using hamstring autograft from January 2019 to June 2021.The patients were prospectively recruited to undergo ACL reconstruction with either 5-strand hamstring graft (group A) or 4-strand hamstring graft (group B).

The STEP Program-A Qualitative Study of the Supportive Therapeutic Excursion Program and Its Effect on Enabling Parental Self-Efficacy and Connectedness after the Stress-Experience of the NICU.

As a child is born, so are the parents with new roles assumed. Attachment is secured, and parents quickly become the experts in their child. With preterm birth, however, this quiet and essential period of discovery is interrupted.

The Use of Fixation Suture to Treat Inferonasal Hypertrophic Bleb after Xen Gel Stent Implant: A Case Report.

We report a case of an inferonasal hypertrophic bleb complication which formed 5 months after Xen Gel Stent implantation for intraocular pressure (IOP) control in a primary open-angle glaucoma patient and its management using a fixation suture. The patient underwent an uneventful right-eye phacoemulsification and intraocular lens implantation combined with Xen Gel Stent ab interno implantation surgery. A month after the surgery, a second needling was performed due to a flat bleb and increased IOP.

Neurodevelopmental Outcomes of Infants at <29 Weeks of Gestation Born in Canada Between 2009 and 2016.

Objective: To evaluate changes in mortality or significant neurodevelopmental impairment (NDI) in children born at <29 weeks of gestation in association with national quality improvement initiatives.

Study Design: This longitudinal cohort study included children born at 22 to 28 weeks of gestation who were admitted to Canadian neonatal intensive care units between 2009 and 2016. The primary outcome was a composite rate of death or significant NDI (Bayley Scales of Infant and Toddler Development, Third Edition score <70, severe cerebral palsy, blindness, or deafness requiring amplification) at 18-24 months corrected age.

Remote ischemic conditioning in necrotizing enterocolitis: study protocol of a multi-center phase II feasibility randomized controlled trial.

Purpose: Remote ischemic conditioning (RIC) is a maneuver involving brief cycles of ischemia reperfusion in an individual's limb. In the early stage of experimental NEC, RIC decreased intestinal injury and prolonged survival by counteracting the derangements in intestinal microcirculation. A single-center phase I study demonstrated that the performance of RIC was safe in neonates with NEC.

L'évaluation et la prise en charge de la paralysie néonatale du plexus brachial.

La paralysie néonatale du plexus brachial, qui se manifeste à la naissance, peut être débilitante et avoir des conséquences prolongées. La présentation à la naissance dépend de l'importance de la lésion nerveuse et peut varier entre une faiblesse transitoire et une parésie globale qui touche l'amplitude active des mouvements. Il est essentiel de procéder à des examens cliniques sériels après la naissance et pendant la période néonatale (jusqu'à l'âge d'un mois) pour évaluer le rétablissement et prédire le pronostic à long terme.

The evaluation and management of neonatal brachial plexus palsy.

Neonatal brachial plexus palsy presents at birth and can be a debilitating condition with long-term consequences. Presentation at birth depends on the extent of nerve injury, and can vary from transient weakness to global paresis, with active range of motion affected. Serial clinical examination after birth and during the neonatal period (first month of life) is crucial to assess recovery and predicts long-term outcomes.

Impact of symptomatic vitreous degeneration on photopic and mesopic contrast thresholds.

Clinical Relevance: Contrast thresholds under photopic and mesopic luminance conditions are compromised in subjects with vitreous degeneration. A plausible explanation is needed for the visual discomfort expressed by patients suffering from symptomatic vitreous degeneration.

Background: The current study investigates the effect of symptomatic vitreous degeneration on photopic and mesopic contrast at high spatial frequencies.

Treatment of Open-Angle Glaucoma and Ocular Hypertension with Preservative-Free Tafluprost/Timolol Fixed-Dose Combination Therapy: UK and Ireland Results from the VISIONARY Study.

Introduction: Reducing intraocular pressure (IOP), the only modifiable risk factor for open-angle glaucoma (OAG), is important for the preservation of vision and slowing of disease progression. Preservative-free tafluprost (0.0015%)/timolol (0.

3D Finite Element Model on Drilling of CFRP with Numerical Optimization and Experimental Validation.

When drilling Carbon Fibre-Reinforced Plastic (CFRP) materials, achieving acceptable hole quality is challenging while balancing productivity and tool wear. Numerical models are important tools for the optimization of drilling CFRP materials in terms of material removal rate and hole quality. In this research, a macro-Finite Element (FE) model was developed to accurately predict the effect of drill tip geometry on hole entry and exit quality.

Higher Energy, Lipid, and Carbohydrate Provision to Very Low-Birth-Weight Infants Is Differentially Associated With Neurodevelopment at 18 Months, Despite Consistent Improvements in Weight Gain.

Background: The impact of suboptimal intakes on neurodevelopment of very low-birth-weight (VLBW, <1500 g) infants, particularly those born small for gestational age, <26 weeks, <1000 g, or with morbidities is not well defined. We investigated how macronutrient/energy intakes are associated with growth and neurodevelopment among VLBW infants, adjusted for the aforementioned vulnerabilities. Our hypothesis was that higher nutrient intakes would be positively associated with weight gain and neurodevelopment.

Guidelines for surfactant replacement therapy in neonates.

Surfactant replacement therapy (SRT) plays a pivotal role in the management of neonates with respiratory distress syndrome (RDS) because it improves survival and reduces respiratory morbidities. With the increasing use of noninvasive ventilation as the primary mode of respiratory support for preterm infants at delivery, prophylactic surfactant is no longer beneficial. For infants with worsening RDS, early rescue surfactant should be provided.

Characteristics and outcomes of preterm neonates according to number of doses of surfactant received.

Objectives: To identify characteristics and outcomes of infants who received multiple doses of surfactant vs those who received one dose or none.

Study Design: In this retrospective study, we included neonates of 22-28 weeks' gestation admitted to NICUs in the Canadian Neonatal Network. Patients were divided into three groups: no surfactant, single dose, and multiple doses.
