RESUMO
Persistent Patent Ductus Arteriosus (PDA) is prevalent among extremely preterm infants, with its occurrence inversely related to gestational age. A persistent PDA correlates with increased mortality and morbidities such as intraventricular hemorrhage, pulmonary hemorrhage, chronic lung disease, bronchopulmonary dysplasia, and necrotizing enterocolitis as observed clinically. Conversely, numerous randomized controlled trials have failed to demonstrate significant benefits from PDA treatment. One contributing factor to these conflicting findings is that PDA affects each individual differently depending on the cardiovascular decompensation and its hemodynamic impact. PDA management should be based on the hemodynamic significance, rather than just the presence or size of PDA. This comprehensive narrative review paper describes echocardiographic parameters that allow a better understanding of the hemodynamic impact of PDA. A newer modality, like lung ultrasound, is also described here as an adjunct to assess the PDA impact on the lungs from pulmonary overcirculation.
RESUMO
BACKGROUND: Wire-guided localization has been the mainstay of localization techniques for non-palpable breast and axillary lesions prior to excision. Evidence is still growing for relatively newer localization technologies. This study evaluated the efficacy of the wireless localization technology, SCOUT®, for both breast and axillary surgery. METHODS: Data were extracted from a prospective database (2021-2023) of consecutive patients undergoing wide local excision, excisional biopsy, targeted axillary dissection, or axillary lymph node dissection with SCOUT at a high-volume tertiary centre. Rates of successful reflector placement, intraoperative lesion localization, and reflector retrieval were evaluated. A survey of surgeon-reported ease of lesion localization and reflector retrieval was also evaluated. CLINICAL TRIAL REGISTRATION: ACTRN386751. RESULTS: One-hundred-ninety-five reflectors were deployed in 172 patients. Median interval between deployment and surgery was 3 days (range 1-20) and mean distance from reflector to lesion was 3.2 mm (standard deviation, SD 3.1). Rate of successful localization and reflector retrieval was 100% for both breast and axillary procedures. Mean operating time was 65.8 min (SD 33). None of the reflectors migrated. No reflector deployment or localization-related complications occurred. Ninety-eight percent of surgeons were satisfied with ease of localization for the first half of cases. CONCLUSION: SCOUT is an accurate and reliable method to localize and excise both breast and axillary lesions, and it may overcome some of the limitations of wire-guided localization.

Point-of-care ultrasound (POCUS) has increasingly been used by neonatal providers in neonatal intensive care units in the United States. However, there is a lack of literature addressing the complexities of POCUS coding and billing practices in the United States. This article describes the coding terminology and billing process especially those relevant to neonatal POCUS. We elucidate considerations for neonatal POCUS billing framework and workflow integration. Directions on image storage and supporting documentation to facilitate efficient reimbursement, compliance with billing regulations, and appeal to insurance claim denial are discussed. KEY POINTS: · Code neonatal POCUS procedure precisely allows accurate reimbursement and reduced errors in billing.. · Document details to support medical necessity and reimbursement claims effectively.. · Adhere to regulations to avoid audits, denials, and ensure proper reimbursement..
RESUMO
Metaplastic breast cancer is a rare aggressive subtype of breast cancer for which there are no clear treatment guidelines regarding the optimal surgical approach. This systematic review and meta-analysis aimed to evaluate survival outcomes of patients with metaplastic breast cancer undergoing breast conservation compared with mastectomy. We identified studies from MEDLINE, Pubmed, EMBASE, Google Scholar, the Cochrane Library Register of Controlled Trials and the EBM Reviews Register. Studies were deemed suitable for inclusion where they compared breast-conserving surgery to mastectomy with the primary outcome of overall survival. Survival data were pooled using a random-effects model. From the 456 citations screened by our search, three studies were assessed as eligible for inclusion. There were a total of 2995 patients who underwent mastectomy and 1909 who underwent breast conservation. The median follow-up time was 43 months. Meta-analysis demonstrated no significant difference between breast conservation and mastectomy (pooled HR 0.89, 95% CI, 0.56-1.42, p = 0.631). Wide local excision, in conjunction with adjuvant radiation and judicious use of chemotherapy, may be a reasonable alternative to mastectomy as surgical management of metaplastic breast cancer as part of an individualized, multidisciplinary approach.
RESUMO
BACKGROUND: Wire localisation (WL) is the "gold standard" localisation technique for wide local excision (WLE) of non-palpable breast lesions but has disadvantages that have led to the development of wireless techniques. This study compared the cost-effectiveness of radar localisation (RL) to WL. METHODS: This was a single-institution study of 110 prospective patients with early-stage breast cancer undergoing WLE using RL with the SCOUT® Surgical Guidance System (2021-2023) compared with a cohort of 110 patients using WL. Margin status, re-excision rates, and surgery delays associated with preoperative localisation were compared. Costs from a third-party payer perspective in Australian dollars (AUD$) calculated by using microcosting, break-even point, and cost-utility analyses. RESULTS: A total of 110 WLEs using RL cost a total of AUD$402,281, in addition to the device cost of AUD$77,150. The average additional cost of a surgery delay was AUD$2318. Use of RL reduced the surgery delay rate by 10% (p = 0.029), preventing 11 delays with cost savings of AUD$25,496. No differences were identified in positive margin rates (RL: 11.8% vs. WL: 17.3%, p = 0.25) or re-excision rates (RL: 14.5% vs. WL: 21.8%, p = 0.221). In total, 290 RL cases are needed to break even. The cost of WLE using RL was greater than WL by AUD$567. There was a greater clinical benefit of 1.15 quality-adjusted life-years (QALYs) and an incremental cost-utility ratio of AUD$493 per QALY favouring RL. CONCLUSIONS: Routine use of RL was a more cost-effective intervention than WL. Close to 300 RL cases are likely needed to be performed to recover costs of the medical device. CLINICAL TRIAL REGISTRATION: ACTRN12624000068561.

BACKGROUND: Superparamagnetic iron oxide (SPIO) (Magtrace®) is a non-radioactive liquid tracer that can stay in the sentinel lymph nodes for 30 days. Injection of SPIO at time of primary breast surgery where upfront sentinel lymph node biopsy (SLNB) is not immediately indicated allows for a return to theatre if pathology then identifies invasive disease. SLNB is associated with paraesthesia, pain, seroma formation and lymphoedema risk. Hence, our study aims to assess the use of SPIO to avoid upfront SLNB in breast surgery for ductal carcinoma in situ (DCIS) and prophylaxis. METHODS: Retrospective single-centre study of consecutive patients who underwent injection of SPIO tracer at time of primary breast surgery to avoid upfront SLNB at Chris O'Brien Lifehouse, Sydney, NSW, Australia over a 10-month period. RESULTS: SPIO was injected 38 times, with 34 at time of mastectomy and four cases at time of wide local excision. The indication for surgery was DCIS in 18 cases, risk reduction in 17 cases and other indications in three patients. Six cases (15.8%) required delayed SLNB (D-SLNB) due to the finding of invasive disease on post-operative histopathology. All patients who underwent D-SLNB had nodes successfully localized with SPIO. CONCLUSION: In our cohort, 84.2% of cases were able to avoid upfront SLNB, and hence avoid the associated complications of SLNB. SPIO injection was successful in localizing the SLN in all cases at time of surgery for D-SLNB. This technique was safe with few associated complications.

OBJECTIVE: Administering surfactant timely and appropriately is important to minimize lung injury but remains challenging in preterm neonates with respiratory distress syndrome. The published literature supports that lung ultrasound (LUS) score can predict surfactant need. Neonatal LUS scanning specification and parameter setting guidelines have been recently published for standardization. However, variations in scanning protocols and machine settings hinder its clinical implementation widely. This observational study aims to internally validate the suggested LUS protocol in a neonatal intensive care unit to establish a correlation between LUS scores and surfactant need as the first step of integrating LUS in the clinical practice. STUDY DESIGN: LUS was performed on 40 eligible preterm neonates within 3 hours after birth or before surfactant administration between May 2020 and March 2021. The neonates were between 27 and 32 weeks' gestational age, and all had respiratory distress. Neonates with known congenital anomalies were excluded. A high-frequency linear probe was used to obtain LUS images from six lung zones which were scored using a 0 to 3 system, yielding a maximum of 18 points. Treating physicians were blinded to the LUS score. Receiver operating characteristic analysis determined the optimal LUS score cutoff for predicting surfactant need. RESULTS: Fifteen of the 40 neonates (38%) required higher oxygen fraction and received surfactant. In our cohort, an LUS score ≥10 was identified as the optimal cutoff for predicting surfactant need, with a sensitivity of 80% and specificity of 84%. The area under the curve was 0.8 (p = 0.0003). LUS predicted surfactant need at a median of 3.5 hours earlier than traditional clinical decision (p < 0.0037). CONCLUSION: LUS is a helpful adjunct for predicting surfactant need in preterm neonates. This study describes an approach to implement the LUS protocol and score for clinical decision-making in the clinical practice. KEY POINTS: · LUS is a helpful adjunct for predicting surfactant need in preterm neonates.. · Machine setting variation and probe selection may affect LUS image and score.. · LUS score should be validated at the local unit before clinical implementation..
RESUMO
Phyllodes tumours (PTs) are rare fibroepithelial lesions of the breast that are classified as benign, borderline, or malignant. As little is known about the molecular underpinnings of PTs, current diagnosis relies on histological examination. However, accurate classification is often difficult, particularly for distinguishing borderline from malignant PTs. Furthermore, PTs can be misdiagnosed as other tumour types with shared histological features, such as fibroadenoma and metaplastic breast cancers. As DNA methylation is a recognised hallmark of many cancers, we hypothesised that DNA methylation could provide novel biomarkers for diagnosis and tumour stratification in PTs, whilst also allowing insight into the molecular aetiology of this otherwise understudied tumour. We generated whole-genome methylation data using the Illumina EPIC microarray in a novel PT cohort (n = 33) and curated methylation microarray data from published datasets including PTs and other potentially histopathologically similar tumours (total n = 817 samples). Analyses revealed that PTs have a unique methylome compared to normal breast tissue and to potentially histopathologically similar tumours (metaplastic breast cancer, fibroadenoma and sarcomas), with PT-specific methylation changes enriched in gene sets involved in KRAS signalling and epithelial-mesenchymal transition. Next, we identified 53 differentially methylated regions (DMRs) (false discovery rate < 0.05) that specifically delineated malignant from non-malignant PTs. The top DMR in both discovery and validation cohorts was hypermethylation at the HSD17B8 CpG island promoter. Matched PT single-cell expression data showed that HSD17B8 had minimal expression in fibroblast (putative tumour) cells. Finally, we created a methylation classifier to distinguish PTs from metaplastic breast cancer samples, where we revealed a likely misdiagnosis for two TCGA metaplastic breast cancer samples. In conclusion, DNA methylation alterations are associated with PT histopathology and hold the potential to improve our understanding of PT molecular aetiology, diagnostics, and risk stratification. © 2024 The Authors.

OBJECTIVE: Delayed cord clamping (DCC) is recommended for all neonates; however, adapting such practice can be slow or unsustainable, especially among preterm neonates. During DCC neonates are exposed to a cool environment, raising concerns for neonatal hypothermia. Moderate hypothermia may induce morbidities that counteract the potential benefits of DCC. A quality improvement project on a thermoregulation-focused DCC protocol was implemented for neonates less than 34 weeks' gestational age (GA). The aim was to increase the compliance rate of DCC while maintaining normothermia. STUDY DESIGN: The DCC protocol was implemented on October 1, 2020 in a large Level III neonatal intensive care unit. The thermoregulation measures included increasing delivery room temperature and using heat conservation supplies (sterile polyethylene suit, warm towels, and thermal pads). Baseline characteristics, the compliance rate of DCC, and admission temperatures were compared 4 months' preimplementation and 26 months' postimplementation RESULTS: The rate of DCC increased from 20% (11/54) in preimplementation to 57% (240/425) in postimplementation (p < 0.001). The balancing measure of admission normothermia remained unchanged. In a postimplementation subgroup analysis, the DCC cohort had less tendency to experience admission moderate hypothermia (<36°C; 9.2 vs. 14.1%, p = 0.11). The DCC cohort had more favorable secondary outcomes including higher admission hematocrit, less blood transfusions, less intraventricular hemorrhage, and lower mortality. Improving the process measure of accurate documentation could help to identify implementation barriers. CONCLUSION: Performing DCC in preterm neonates was feasible and beneficial without increasing admission hypothermia. KEY POINTS: · Thermoregulation-focused DCC protocol was implemented to increase DCC while maintaining normothermia.. · DCC rate increased from 20 to 57% while admission normothermia rate remained the same.. · DCC practice on preterm neonates is safe and feasible while maintaining normothermia..
RESUMO
Transcatheter device closure of patent ductus arteriosus (PDA) in preterm infants has been proven to be a feasible and safe technique with promising results when compared to surgical ligation. However, managing transport and anaesthesia in extremely premature infants with haemodynamically significant PDA and limited reserves presents unique challenges. This review article focuses on the key considerations throughout the clinical pathway for the PDA device closure, including referral hospital consultation, patient selection, intra- and inter-hospital transport, and anaesthesia management. The key elements encompass comprehensive patient assessment, meticulous airway management, optimised ventilation strategies, precise thermoregulation, patient-tailored sedation protocols, vigilant haemodynamic monitoring, and safe transport measures throughout the pre-operative, intra-operative, and post-operative phases. A multidisciplinary approach enhances the chances of procedure success, improves patient outcomes, and minimises the risk of complications.
RESUMO
Point-of-care ultrasound (POCUS) holds immense potential to manage critically deteriorating infants within the neonatal intensive care unit (NICU) and is increasingly used in neonatal clinical practice worldwide. Recent ultrasound-based protocols such as the Sonographic Assessment of liFe-threatening Emergencies-Revised (SAFE-R) and Crashing Neonate Protocol (CNP) offer step-by-step guidance for diagnosing and addressing reversible causes of cardiorespiratory collapse. Traditionally, pulseless electrical activity (PEA) has been diagnosed solely based on absent pulses on clinical examination, disregarding myocardial activity. However, integrating POCUS into resuscitation unveils the concept of pseudo-PEA, where cardiac motion activity is observed visually on the ultrasound but fails to generate a detectable pulse due to inadequate cardiac output. Paradoxically, existing neonatal resuscitation protocols lack directives for identifying and effectively leveraging pseudo-PEA insights in infants, limiting their potential to enhance outcomes. Pseudo-PEA is extensively described in adult literature owing to routine POCUS use in resuscitation. This review article comprehensively evaluates the adult pseudo-PEA literature to glean insights adaptable to neonatal care. Additionally, we propose a simple strategy to integrate POCUS during neonatal resuscitation, especially in infants who do not respond to routine measures. CONCLUSION: Pseudo-PDA is a newly recognized diagnosis in infants with the use of POCUS during resuscitation. This article highlights the importance of cross-disciplinary learning in tackling emerging challenges within neonatal medicine. WHAT IS KNOWN: ⢠Point-of-Care ultrasound (POCUS) benefits adult cardiac arrest management, particularly in distinguishing true Pulseless Electrical Activity (PEA) from pseudo-PEA. ⢠Pseudo-PEA is when myocardial motion can be seen on ultrasound but fails to generate palpable pulses or sustain circulation despite evident cardiac electrical activity. WHAT IS NEW: ⢠Discuss recognition and management of pseudo-PEA in infants. ⢠A proposed algorithm to integrate POCUS into active neonatal cardiopulmonary resuscitation (CPR) procedures.

OBJECTIVE: To bring screening and management of neonatal hypoglycemia in alignment with the 2011 AAP hypoglycemia clinical report METHODS: A multidisciplinary team developed a quality improvement initiative for neonatal hypoglycemia in neonates ≥35 weeks gestational age in a Level III neonatal intensive care unit between July 2020 and December 2021. A key driver diagram identified interventions for plan-do-study-act testing with corresponding measures to implement a hypoglycemia management protocol and improve adherence to AAP guidelines. RESULTS: Time to first blood glucose measurement increased from 49.8 to 122.7 min of life and time to first enteral feed decreased from 14.2 to 3.6 h of life. Neonates receiving intravenous dextrose decreased from 97.1 to 24.7% and discharge rates as a mother-neonate dyad increased from 35 to 62.4%. CONCLUSIONS: Adherence to the AAP guidelines improved during testing and implementation of a hypoglycemia protocol and was associated with an increased mother-neonate dyad discharge rate.
RESUMO
BACKGROUND: COVID-19-associated visitor restrictions altered parents' involvement in their infant's care in the neonatal intensive care unit (NICU). PURPOSE: The purpose of this article is to explore how restrictions affected parents' perceptions of experience in the NICU and to build a conceptual model of communication flow during times of crisis. METHODS: This qualitative study was set in a level III 52-bed NICU. Using data from an open-ended survey question, a multitiered thematic analysis was used. RESULTS: Four broad themes emerged: communication, gratitude, release, and containment of emotionality. These 4 themes interacted codependently and manifested differently as COVID-related visitor policies were put in place. Parents' characterization of communication also varied depending on the visitation policies. Before COVID, parents were more likely to reflect on communication. During COVID, parents expressed more gratitude, while containing negative emotions-sometimes using gratitude to soften the blow of bad feedback. IMPLICATIONS FOR PRACTICE AND RESEARCH: Our theoretical model suggests that gratitude may serve as a form of "reciprocal care" to providers during a period of crisis and extreme stress. Use of high-quality communication between providers and parents in the NICU is necessary to understand parental concerns or negative experience.

The effect of psychiatric comorbidity on pregnancy outcome among SARS-CoV-2 positive women with asymptomatic and mildly symptomatic infections remains largely unknown. We reviewed the electronic medical records of all pregnant women who received care at Mayo Health System and tested positive for SARS-CoV-2 (RT-PCR) from March 2020 through October 2021. Among 789 patients, 34.2% (n = 270) had psychiatric comorbidity. Of those with psychiatric comrobidity, 62.2% (n = 168) had depression prior to pregnancy, and 5.2% (n = 14) reported new-onset depression during pregnancy. Before pregnancy, 65.6% (n = 177) had anxiety, and 4.4% (n = 12) developed anxiety during pregnancy Thirteen percent of SARS-CoV-2 positive pregnant women (n = 108) received psychotropic medication during pregnancy. In addition, 6.7% (n = 18) and 10.7% (n = 29) of pregnant women with psychiatric comorbidity had documented nicotine, cannabis and/ or illicit substance use during and prior to pregnancy, respectively. We depicted a significantly higher risk for cesarean delivery [35.6% vs. 24.9%) in asymptomatic and mildly symptomatic SARS-CoV-2 positive pregnant women with psychiatric comorbidity. In conclusion, the prevalence rates of depression, anxiety, and prescribed antidepressant medications during pregnancy among asymptomatic and mildly symptomatic SARS-CoV-2 infected women were substantially higher than average, which negatively impacted pregnancy and neonatal outcomes.

Background: Cancer is a significant problem for the South Pacific region due to a range of complex health challenges. Currently gaps in diagnosis, treatment and palliative care are significant, and while governmental commitment is strong, economic constrains limit health system strengthening. Alliances have been successful in strengthening non-communicable disease and cancer control policy and services in resource constrained settings. A regional coalition approach has therefore been recommended as an effective solution to addressing many of the challenges for cancer control in the South Pacific. However, evidence regarding the effective mechanisms for development of alliances or coalitions is scarce. This study aimed to 1) create a Coalition Development Framework; 2) assess the use of the Framework in practice to co-design a South Pacific Coalition. Methods: Creation of the Coalition Development Framework commenced with a scoping review and content analysis of existing literature. Synthesis of key elements formed an evidence-informed step-by-step guide for coalition-building. Application of the Framework comprised consultation and iterative discussions with key South Pacific cancer control stakeholders in Fiji, New Caledonia, Papua New Guinea, Samoa and Tonga. Concurrent evaluation of the Framework utilising Theory of Change (ToC) and qualitative analysis of stakeholder consultations was undertaken. Findings: The finalised Coalition Development Framework comprised four phases with associated actions and deliverables: engagement, discovery, unification, action and monitoring. Application of the Framework in the South Pacific identified overwhelming support for a Cancer Control Coalition through 35 stakeholder consultations. Framework phases enabled stakeholders to confirm coalition design and purpose, strategic imperatives, structure, local foundations, barriers and facilitators, and priorities for action. ToC and thematic consultation analysis confirmed the Framework to be an effective mechanism to drive engagement, unification and action in alliance-building. Interpretation: A Coalition to drive cancer control has significant support among key Pacific stakeholders, and establishment can now be commenced. Importantly results confirm the effective application of the Coalition Development Framework in an applied setting. If momentum is continued, and a regional South Pacific Coalition established, the benefits in reducing the burden of cancer within the region will be substantial. Funding: This work was completed for a Masters of Public Health project. Cancer Council Australia provided project funding.
RESUMO
OBJECTIVE: Monitoring heart rate (HR) and oxygen saturation (SpO2) in infants is essential in the neonatal intensive care unit. Wireless pulse oximeter technology has been advancing but with limited accuracy data on preterm infants. This observational study compared HR and SpO2 of the wireless Owlet Smart Sock 3 (OSS3) to the wired Masimo SET (Masimo) pulse oximeter in preterm or <2.5 kg infants. STUDY DESIGN: Twenty-eight eligible infants were enrolled. They weighed between 1.7 and 2.5 kg and were without anomalies or medical instability. OSS3 and Masimo simultaneously monitored HR and SpO2 for 60 minutes. The data were aligned by time epoch and filtered for poor tracings. The agreement was compared using the Pearson's correlation coefficient, the Bland-Altman method, average root mean square (ARMS), and prevalence and bias adjusted kappa (PABAK) analyses. RESULTS: Two infants' data were excluded due to motion artifacts or device failures. The corrected gestational age and current weights were 35 ± 3 weeks and 2.0 ± 0.2 kg (mean ± standard deviation), respectively. Over 21 hours of data showed that HR was strongly correlated between the two devices (r = 0.98, p < 0.001), with a difference of -1.3 beats per minute (bpm) and the limit of agreement (LOA) -6.3 to 3.4 bpm based on the Bland-Altman method. SpO2 was positively correlated between the two devices (r = 0.71, p < 0.001) with a SpO2 bias of 0.3% (LOA: -4.6 to 4.5%). The estimated ARMS of OSS3 compared with Masimo was 2.3% for SpO2 in the 70 to 100% range. The precision decreased with lower SpO2. A strong agreement (PABAK = 0.94) was between the two devices on whether SpO2 was above or below 90%. CONCLUSION: OSS3 provided comparable HR and SpO2 accuracy to Masimo in preterm or <2.5 kg infants. Motion artifacts, lack of arterial blood gas comparisons, and lack of racial and ethnic diversity are the study limitations. More OSS3 data on the Lower HR and SpO2 ranges were needed before implementing inpatient use. KEY POINTS: · Pulse oximeters are vital for monitoring preterm infants' HR and SpO2 levels.. · Limited data exist on the accuracy of the wireless OSS3 on preterm infants.. · This observational study found that the OSS3 is comparable to the Masimo SET in measuring HR and SpO2 in preterm or <2.5 kg infants..
RESUMO
Despite recent improvements in neonatal care, moderate to severe bronchopulmonary dysplasia (BPD) is still associated with high mortality and with an increased risk of developing pulmonary hypertension (PH). This scoping review provides an updated overview of echocardiographic and lung ultrasound biomarkers associated with BPD and PH, and the parameters that may prognosticate their development and severity, which could be clinically helpful to undertake preventive strategies. A literature search for published clinical studies was conducted in PubMed using MeSH terms, free-text words, and their combinations obtained through appropriate Boolean operators. It was found that the echocardiography biomarkers for BPD, and especially those assessing right ventricular function, are reflective of the high pulmonary vascular resistance and PH, indicating a strong interplay between heart and lung pathophysiology; however, early assessment (e.g., during the first 1-2 weeks of life) may not successfully predict later BPD development. Lung ultrasound indicating poor lung aeration at day 7 after birth has been reported to be highly predictive of later development of BPD at 36 weeks' postmenstrual age. Evidence of PH in BPD infants increases risk of mortality and long-term PH; hence, routine PH surveillance in all at risk preterm infants at 36 weeks, including an echocardiographic assessment, may provide useful information. Progress has been made in identifying the echocardiographic parameters on day 7 and 14 to predict later development of pulmonary hypertension. More studies on sonographic markers, and especially on echocardiographic parameters, are needed for the validation of the currently proposed parameters and the timing of assessment before recommendations can be made for the routine clinical practice.
RESUMO
There is no universal consensus on management of patent ductus arteriosus (PDA) in preterm infants and it varies significantly worldwide, even among the clinicians within units. The decision to treat requires a thorough understanding of the clinical status of the patient, clinical evaluation of PDA, echocardiographic diagnosis, and hemodynamic impact of ductal shunt on the pulmonary and systemic circulation. In this article, updated evidence on the efficacy and adverse effects of pharmacological treatment options and expectant management are presented, while highlighting the long-term benefits of PDA treatment remains equivocal and controversial. The authors propose a schematic targeted PDA treatment approach based on gestational and chronological age for practical clinical use, and they emphasize important future directions including advancement in PDA device closure techniques, diagnostic echo-parameters, hemodynamic evaluation to assess the impact on other organs, and understanding the long-term outcomes.
RESUMO
IMPORTANCE: Critically ill neonates can be vulnerable to positional deformities and joint contractures. Early splints, along with dynamic exercise, may lead to long-term functional improvement. Making splints to perfectly contour neonates' small joints and bodies is challenging. An ill-fitted splint can lead to skin ulcers, nerve damage, poor compliance, and discomfort. Three-dimensional (3D) printing has been applied to create customized, cost-effective, and lightweight orthoses that may be promising for neonates. OBJECTIVE: To explore the feasibility of scanning, designing, and printing 3D splints for neonates. SETTING: A large neonatal intensive care unit (NICU) in a university teaching hospital. METHOD: Case series of three neonates in a NICU who had deformities or joint contractures that would benefit from early static splints. We created customized splints for neonates using 3D scanning, digital design software, and 3D printing technology. We monitored the neonates' comfort and clinical improvement. RESULTS: One neonate with a congenital neck deformity had a neck splint created from 3D body-scanned images. Another neonate with a hand deformity was measured and had 3D digitally designed hand splints made. The same hand splint design was modified to fit a third neonate's hand with new measurements. All splints were 3D printed using specialized lightweight materials. The neonates tolerated the splints well. CONCLUSIONS AND RELEVANCE: 3D printing technology is feasible for and applicable to NICU neonates. Advancing 3D technology should focus on upgrading scanning quality, improving splint design, and speeding up printing. Further research to evaluate the long-term benefits of early splinting is needed. What This Article Adds: This is the first published article to discuss the feasibility of using 3D printing technology to create customized splints for fragile neonates. Neonates, especially critically ill ones with congenital defects, may benefit from early splinting to preserve function and development. Neonates are the most challenging patients to make a perfect-fit splint for, and 3D printing may offer a potential solution.
