Reporting Quality and Risk of Bias Analysis of Published RCTs Assessing Anti-CGRP Monoclonal Antibodies in Migraine Prophylaxis: A Systematic Review. J Clin Med 2024; 13:1964. [PMID: 38610729 PMCID: PMC11012539 DOI: 10.3390/jcm13071964] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/29/2024] [Revised: 03/19/2024] [Accepted: 03/25/2024] [Indexed: 04/14/2024] Open
Abstract
Objective: Phase II/III randomized clinical trials (RCTs) are vulnerable to many types of bias beyond randomization. Insights into the reporting quality of RCTs involving migraine patients treated with monoclonal antibodies targeting the calcitonin gene-related peptide system (anti-CGRP MAbs) are currently lacking. Our aim was to analyze the reporting quality of phase II/III RCTs involving migraine patients treated with anti-CGRP MAbs. Methods: A systematic search was performed on the PubMed and EMBASE databases, according to PRISMA guidelines, for relevant RCTs in either episodic or chronic migraine prevention. Additionally, an adapted version of the 2010 CONSORT statement checklist was utilized. The ROBvis online tool was used to document the risk of bias. Results: From the initially identified 179 articles, we finally found 31 RCTs that were eligible for evaluation. The average CONSORT compliance was 88.7% (69.7-100%), while 93.5% (N = 29) of the articles had a compliance greater than 75%. Twenty-eight CONSORT items were reported in more than 75% of the articles. The average compliance of the analyzed RCTs was 93.9% for Galcanezumab, 91.3% for Fremanezumab, followed by 85.4% for Erenumab and Eptinezumab studies. Implementation of the ROB2 tool showed some concerning "missing information" arising from the inadequate reporting. Specifically, 50% of the studies (N = 16) were categorized as having inadequate information regarding the randomization process. Conclusions: Adequate reporting quality was disclosed in the evaluated RCTs with anti-CGRP MAbs in migraine prevention. However, some methodological issues need to be highlighted to be addressed in future studies assessing the efficacy of new molecules targeting CGRP or other candidate pathways implicated in migraine pathophysiology.

Maternal Obesity Modulates Cord Blood Concentrations of Proprotein Convertase Subtilisin/Kexin-type 9 Levels. J Endocr Soc 2024; 8:bvae031. [PMID: 38440108 PMCID: PMC10910593 DOI: 10.1210/jendso/bvae031] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/22/2023] [Indexed: 03/06/2024] Open
Abstract
Context In utero exposure to maternal obesity or diabetes is considered a pro-inflammatory state. Objective To evaluate whether cord blood proprotein convertase subtilisin/kexin-type 9 (PCSK9), which is regulated by inflammation and metabolic derangements, is elevated in neonates born to overweight, obese, or diabetic mothers. Methods A retrospective study in full-term neonates born between 2010 and 2023, at Brigham and Women's Hospital. There were 116 neonates included in our study, of which 74 (64%) were born to overweight/obese mothers and 42 (36%) were born to nonoverweight/nonobese mothers. Results Neonates born to overweight/obese mothers had significantly higher cord blood concentrations of PCSK9 compared with neonates born to nonoverweight/nonobese group (323 [253-442] ng/mL compared with 270 [244-382] ng/mL, P = .041). We found no significant difference in cord blood concentrations of PCSK9 between neonates of diabetic mothers compared with neonates of nondiabetic mothers. In multivariate linear regression analysis, higher cord plasma PCSK9 concentration was significantly associated with maternal overweight/obesity status (b = 50.12; 95% CI, 4.02-96.22; P = .033), after adjusting for gestational age, birth weight, male sex, and intrauterine growth restriction. Conclusion Neonates born to mothers with overweight/obesity have higher cord blood PCSK9 concentrations compared with the nonoverweight/nonobese group, and higher cord blood PCSK9 concentrations were significantly associated with maternal overweight/obesity status, after adjusting for perinatal factors. Larger longitudinal studies are needed to examine the role of PCSK9 in the development of metabolic syndrome in high-risk neonates born to overweight, obese, or diabetic mothers.

Minimal invasive surfactant therapy in preterm infants with respiratory distress syndrome: a single-center experience. Minerva Pediatr (Torino) 2024; 76:72-78. [PMID: 33820400 DOI: 10.23736/s2724-5276.21.05867-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/08/2022]
Abstract
BACKGROUND Minimal invasive surfactant therapy (MIST) includes the tracheal instillation of surfactant via a thin catheter for the treatment of preterm infants with respiratory distress syndrome (RDS). We aimed to evaluate the impact of MIST compared to intubation, surfactant, extubation (INSURE) technique on respiratory outcomes. METHODS A prospectively recruited cohort of preterm infants ≤32 weeks with RDS was compared against a historical cohort of infants treated with INSURE. The primary outcome was the need for mechanical ventilation within 72 hours of age and secondary outcomes the overall need and duration of mechanical ventilation, the development of bronchopulmonary dysplasia, common morbidities, and survival. RESULTS Thirty-six infants treated with MIST of 29.1±2.2 weeks' gestation and 1219±238 g birthweight compared against 37 infants of 28.8±2.3 weeks' gestation and 1195±336 g birthweight treated with INSURE. A lower proportion of infants treated with MIST required mechanical ventilation within 72 hours of age compared to those treated with INSURE (11% compared 32%, P=0.042). However, no significant differences were noted regarding the overall intubation incidence, bronchopulmonary dysplasia, other morbidities, or survival. CONCLUSIONS In spontaneously breathing infants ≤32 weeks with RDS, the MIST technique was associated with a lower need for intubation within 72 hours of age, but otherwise with no significant differences regarding BPD or other neonatal morbidities.

Predictors of successful extubation from volume-targeted ventilation in extremely preterm neonates. J Perinatol 2024; 44:250-256. [PMID: 38123799 DOI: 10.1038/s41372-023-01849-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/29/2023] [Revised: 11/22/2023] [Accepted: 12/01/2023] [Indexed: 12/23/2023]
Abstract
OBJECTIVE To identify variables associated with extubation success in extremely preterm neonates extubated from invasive volume-targeted ventilation. STUDY DESIGN We retrospectively evaluated 84 neonates ≤28 weeks' gestational age, on their first elective extubation. The primary outcome of successful extubation was defined as non-reintubation within seven days. We used multivariate logistic regression analysis. RESULTS We identified 58 (69%) neonates (mean gestational age of 26.5 ± 1.4 weeks, birthweight 921 ± 217 g) who met the primary outcome. Female sex (OR 1.15, 95% CI 1.01-9.10), higher pre-extubation weight (OR 1.29, 95% CI 1.05-1.59), and pH (OR 2.54, 95% CI 1.54-4.19), and lower pre-extubation mean airway pressure (MAP) (OR 0.49, 95% CI 0.33-0.73) were associated with successful extubation. CONCLUSIONS In preterm neonates, female sex, higher pre-extubation weight and pH, and lower pre-extubation MAP were predictors of successful extubation from volume-targeted ventilation. Evaluation of these variables will likely assist clinicians in selecting the optimal time for extubation in such vulnerable neonates.

Complementary Feeding Practices: Recommendations of Pediatricians for Infants with and without Allergy Risk. Nutrients 2024; 16:239. [PMID: 38257132 PMCID: PMC10819658 DOI: 10.3390/nu16020239] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2023] [Revised: 12/30/2023] [Accepted: 01/08/2024] [Indexed: 01/24/2024] Open
Abstract
AIM To investigate the routine guidance provided by pediatricians concerning the timing of complementary feeding (CF) for both healthy infants and those at a heightened risk of allergies. METHODS A total of 233 pediatricians participated in an anonymous online survey that included questions about demographics and recommendations for CF. Specifically, they provided guidance on the types of foods, preparation methods, supplements, time intervals for introducing new foods to infants at low and high allergy risk, and delayed food introductions for high-risk cases. RESULTS The respondents advised introducing certain foods at specific ages: fruits, starchy non-gluten grains, vegetables, olive oil, and meat were appropriate at 6 months; gluten-rich grains at 7 months; yogurt, hard-boiled eggs, and legumes at 8 months; fish at 8.5 months; and nuts at 9 months. Pediatricians, especially those with less than 15 years of practice, often introduced egg, seafood, gluten-rich grains, legumes, and nuts earlier for high-risk infants. Parenthood and male gender were associated with the earlier introduction of eggs and grains. CONCLUSIONS Greek pediatricians follow a structured food introduction schedule for CF in infants. Interestingly, they tend to delay the introduction of common food allergens and recommend longer intervals between introducing new foods, particularly for high-risk infants. Key Notes: Despite recent evidence-based indications on healthy complementary feeding strategies for infants, discrepancies persist among pediatricians regarding food choices and the order and timing of food introduction, both for healthy infants and those at risk of allergy. Guidance on complementary feeding by pediatricians is influenced by their individual characteristics. Pediatricians tend to delay the introduction of common food allergens and recommend longer intervals between introducing new foods, particularly for high-risk infants.

Nine-Month Continuous Fremanezumab Prophylaxis on the Response to Triptans and Also on the Incidence of Triggers, Hypersensitivity and Prodromal Symptoms of Patients with High-Frequency Episodic Migraine. J Clin Med 2024; 13:386. [PMID: 38256516 PMCID: PMC10816996 DOI: 10.3390/jcm13020386] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2023] [Revised: 01/06/2024] [Accepted: 01/08/2024] [Indexed: 01/24/2024] Open
Abstract
Objective: To investigate whether the incidence of triggers, prodromal symptoms, hypersensitivity symptoms accompanying headache and responses to triptans were modified during a continuous 9-month fremanezumab therapy for migraine prophylaxis. Patients and methods: We studied 63 patients with high-frequency episodic migraine (HFEM). Enrolled patients received fremanezumab for nine consecutive months before defining the response rates and being stratified into treatment responders (≥50-74% reduction in monthly headache days (MHDs)), super responders (≥75%), partial non-responders (<50%) and super non-responders (<30%). Through headache diaries, patients provided data in order to document the impact of fremanezumab on the incidence of triggers, associated symptoms followed by headache and response to triptans (the use of the migraine treatment optimization questionnaire-4 (mTOQ-4)) during the 9-month treatment period. Results: Fremanezumab had early (after 3 monthly cycles) beneficial effects on the response to triptans in the majority of responders with relevant increases in mTOQ-4 scoring, but also in half of partial non-responders. A significant reduction in median days with migraine-associated symptoms was seen in responders after 6 months of therapy with fremanezumab, mostly for osmophobia, photophobia, phonophobia and nausea/vomiting, but partial non-responders also benefited. Likewise, the incidence of self-reported prodromal symptoms was significantly reduced in responders and was modestly diminished in partial non-responders. Triggers remained unaffected in both responders and non-responders. Conclusions: Fremanezumab given for at least 6-9 months may exert neuromodulatory effects in the migraine brain. These effects could result both in the inhibition of migraine chronification, but also in the diminishing of the magnitude of migraine-associated symptoms, mostly in responders and in partial non-responders.

Single center experience with first-intention high-frequency jet vs. volume-targeted ventilation in extremely preterm neonates. Front Pediatr 2024; 11:1326668. [PMID: 38239592 PMCID: PMC10794594 DOI: 10.3389/fped.2023.1326668] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/23/2023] [Accepted: 12/14/2023] [Indexed: 01/22/2024] Open
Abstract
Objectives To examine whether first-intention high-frequency jet ventilation (HFVJ), compared to volume-targeted ventilation (VTV), in extremely preterm infants is associated with lower incidence of bronchopulmonary dysplasia (BPD) and other adverse clinical outcomes. Study design We conducted a retrospective cohort study evaluating neonates with gestational age (GA) ≤28 weeks, who received first-intention HFJV (main exposure) or VTV (comparator), between 11/2020 and 3/2023, with a subgroup analysis including neonates with GA ≤26 weeks and oxygenation index (OI) >5. Results We identified 117 extremely preterm neonates, 24 (GA 25.2 ± 1.6 weeks) on HFJV, and 93 (GA 26.4 ± 1.5 weeks, p = 0.001) on VTV. The neonates in the HFJV group had higher oxygenation indices on admission, higher inotrope use, and remained intubated for a longer period. Despite these differences, there were no statistically significant differences in rates of BPD, survival, or other adverse outcomes between the two groups. In subgroup analysis of 18 neonates on HFJV and 39 neonates on VTV, no differences were recorded in the GA, and duration of mechanical ventilation, while neonates in the HFJV group had significantly lower rates of BPD (50% compared to 83%, p = 0.034), and no significant differences in other adverse outcomes compared to neonates in the VTV group. In neonates ≤26 weeks of GA with OI >5, HFJV was significantly associated with lower rates of BPD (OR 0.21, 95% CI 0.05-0.92), and combined BPD or death (OR 0.18, 95% CI 0.03-0.85), after adjusting for birth weight, and Arterial-alveolar gradient on admission. Conclusions In extremely preterm neonates ≤26 weeks of GA with OI >5, first-intention HFJV, in comparison to VTV, is associated with lower rates of BPD.

Abstract
OBJECTIVE We examined the impact of perinatal factors on cord serum club cell protein (CC16) and the association of CC16 with mechanical ventilation and bronchopulmonary dysplasia (BPD) in preterm neonates. STUDY DESIGN A retrospective cohort study including 60 neonates born with gestational age (GA) < 34 weeks. The impact of categorical perinatal factors on cord blood levels of CC16 was examined with univariate and multivariate regression analyses. RESULTS In neonates with GA < 32 weeks, cord blood CC16 concentrations were significantly lower compared to neonates with GA between 320/7 and 336/7 weeks (5.4 ± 2.5 compared to 7.6 ± 2.9 ng/mL, p = 0.039). Neonates with prolonged rupture of membranes had significantly lower CC16 compared to those without prolonged rupture of membranes (4.0 ± 1.9 compared to 7.2 ± 2.2, p < 0.001). Finally, neonates with BPD had significantly lower CC16, compared to neonates without BPD (4.2 ± 2.1 compared to 7.0 ± 2.2 ng/mL, p = 0.004).Prolonged rupture of membranes was significantly negatively associated with CC16 (b = -2.67, 95% confidence interval [CI] -0.49 to -4.85, p = 0.017), after adjusting for GA (b = 0.23, 95% CI 0.03-0.42, p = 0.022), mode of conception, and mode of delivery. Finally, higher CC16 levels were significantly inversely associated with BPD (odds ratio = 0.33, 95% CI 0.12-0.88, p = 0.028), after adjusting for GA (b = 0.27, 95% CI 0.09-0.78, p = 0.015), and birth weight. CONCLUSION Prolonged rupture of membranes was significantly negatively associated with cord serum CC16, after adjusting for GA, conception, and delivery mode, and CC16 was significantly inversely associated with BPD, after adjusting for GA and birth weight. KEY POINTS · Neonates with prolonged rupture of membranes had lower CC16 levels.. · CC16 was significantly negatively associated with BPD.. · CC16 could be a biomarker of lung injury and BPD..

Nurturing Infants to Prevent Atopic Dermatitis and Food Allergies: A Longitudinal Study. Nutrients 2023; 16:21. [PMID: 38201851 PMCID: PMC10780847 DOI: 10.3390/nu16010021] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/18/2023] [Revised: 12/14/2023] [Accepted: 12/16/2023] [Indexed: 01/12/2024] Open
Abstract
BACKGROUND Atopic dermatitis (AD) at a young age often precedes the development of food allergies. Although AD affects millions of infants worldwide, prenatal and postnatal risk factors, and their association with the development of food allergies later on, are not fully elucidated. This study seeks to investigate AD epidemiology in infancy and its risk factors, examining early-life factors (both prenatal and postnatal) that could contribute to the later development of food allergies. METHODS Between January 2019 and December 2019, 501 infants were included in this prospective cohort study. Longitudinal data collection was performed through maternal interviews, the first one conducted within three days after the delivery and the second within 24 to 36 months after the delivery, encompassing variables such as demographics, family history of atopy, maternal smoking, antibiotic use during pregnancy, the mode of delivery, breastfeeding history, food practices, and greenness exposure within 3 days from delivery, while they were still in the hospital. RESULTS Maternal smoking during pregnancy (p = 0.001) and an older sibling atopy history (p = 0.03) was significantly linked to AD incidence. Cesarean section delivery (p = 0.04) was associated with a higher risk of food allergies in infants with AD. Having a garden at home correlated with a higher likelihood of AD (p = 0.01), and food elimination without medical guidance (p = 0.02) due to AD correlated with an elevated risk of food allergies. CONCLUSIONS Encouraging timely allergenic food introduction while promoting dietary diversity, rich in plant-based foods, maternal smoking cessation, and professional dietary guidance may help minimize AD and food allergy risk. Future studies should address the role of greenness in the development of AD and food allergies.

Abstract
Background: Pregnancy induces a cascade of hemodynamic changes that are likely to affect the maternal systemic and ocular circulation. Objective:The current study aimed to investigate retinal microvasculature alterations in women with preterm and full-term pregnancy using optical coherence tomography angiography (OCT-A). Design:This was a cross-sectional, comparative, single-center study. Methods:The present study included 21 women with preterm pregnancy, who were in the early postpartum period, and 18 controls with full-term pregnancy. Optical coherence tomography angiography imaging was performed to analyze macular microvasculature characteristics at the retinal superficial capillary plexus (SCP) and the choriocapillaris (CC). Results:In females with preterm pregnancy, the mean values of vessel density (VD) at the SCP of the total macular area were significantly higher than those in females with full-term pregnancy (p=0.001), and the mean values of foveal, parafoveal and perifoveal VD at the SCP were higher, though not statistically significant. Similarly, the mean values of perfusion at the SCP of the total macular area were significantly higher in females with preterm pregnancy than controls (p=0.023), while the mean values of foveal, parafoveal and perifoveal perfusion were higher, though not statistically significant. The mean values of foveal avascular zone (FAZ) parameters (area, perimeter, circularity) at the SCP in females with preterm pregnancy did not have any significant differences from those of controls. Concerning the measurements of choroidal parameters, there were no statistically significant differences in subfoveal choroidal thickness, as well as the CC OCT-A characteristics between females with preterm and full-term pregnancy. Conclusions:Our study indicates that retinal blood flow alterations may be present in the early postpartum period in women with preterm pregnancy. Increased macular vasculature may reflect the systemic perfusion changes compensating for placental insufficiency.

Abstract
OBJECTIVE Proprotein Convertase Subtilisin/Kexin-Type 9 (PCSK9), a modulator of low-density lipoprotein (LDL) cholesterol metabolism, has been reported to be a promising biomarker for evaluating lipoprotein metabolism; however, evidence in infants is limited. In the current study, we sought to investigate potential differences in serum PCSK9 levels between infants with deviant birth weight and controls. METHODS We enrolled 82 infants, classified into 33 small (SGA), 32 appropriate (AGA), and 17 large for gestation (LGA) infants. Serum PCSK9 was measured on routine blood analysis within the first postnatal 48 h. RESULTS PCSK9 was significantly higher in SGA as compared to AGA and LGA infants [322 (236-431) as compared to 263 (217-302) and 218 (194-291) ng/ml respectively, p = .011]. In comparison to term AGA infants, PCSK9 was significantly elevated in preterm AGA and SGA infants. We also found a significantly higher level of PCSK9 in term female SGA infants as compared to term male SGA infants [325 (293-377) as compared to 174 (163-216) ng/ml, p = .011]. PCSK9 was significantly correlated with gestational age (R = -0.404, p < .001), birth weight (R = -0.419, p < .001), total cholesterol (R = 0.248, p = .028) and LDL cholesterol (R = 0.370, p = .001). SGA status (OR 2.56, p = .004, 95% CI 1.83-4.28) and prematurity (OR 3.10, p = .001, 95% CI 1.39-4.82) were strongly related to serum PCSK9 levels. CONCLUSION PCSK9 levels were significantly associated with total and LDL cholesterol. Moreover, PCSK9 levels were higher in preterm and SGA infants, suggesting that PCSK9 might be a promising biomarker for evaluating infants with increased later cardiovascular risk.HighlightsWhat's already known? Proprotein Convertase Subtilisin/Kexin-Type 9 (PCSK9) is a promising biomarker for evaluating lipoprotein metabolism; however, evidence in infants is limited. Infants that were born with a deviant birth weight have a unique lipoprotein metabolism profile.What this study adds? Serum PCSK9 levels were significantly associated with total and LDL cholesterol. PCSK9 levels were higher in preterm and small for gestation infants, suggesting that PCSK9 might be a promising biomarker for evaluating infants with increased later cardiovascular risk.

Are the current feeding volumes adequate for the growth of very preterm neonates? Br J Nutr 2023; 130:1338-1342.

Abstract
Postnatal growth failure, a common problem in very preterm neonates associated with adverse neurodevelopmental outcome, has recently been shown not to be inevitable. There is a wide discussion regarding feeding practices of very preterm neonates, specifically regarding feeding volumes and nutrients supply to avoid postnatal growth failure. Current guidelines recommend an energy intake of 115–140 kcal /kg per d with a considerably higher upper limit of 160 kcal/kg per d. The feeding volume corresponding to this energy supply is not higher than 200 ml/kg in most cases. From the other side, randomised and observational studies used higher feeding volumes, and these were associated with better weight gain and growth, while no complications were noted. Taking into account the above, nutritional practices should be individualised in each very and extremely preterm infant trying to reduce postnatal growth failure, pointing out that available data are inconclusive regarding the effect of high-volume feeds on growth. Large clinical trials are necessary to conclude in the best feeding practices of very preterm neonates.

A systematic review and meta-analysis of the role of Doppler ultrasonography of the superior mesenteric artery in detecting neonates at risk of necrotizing enterocolitis. Pediatr Radiol 2023; 53:1989-2003. [PMID: 37310444 PMCID: PMC10497699 DOI: 10.1007/s00247-023-05695-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/03/2023] [Revised: 05/17/2023] [Accepted: 05/18/2023] [Indexed: 06/14/2023]
Abstract
The role of postnatal Doppler measurements of the superior mesenteric artery (SMA) in detecting neonates at risk of necrotizing enterocolitis (NEC) remains uncertain; therefore, we systematically reviewed and meta-analyzed the existing evidence regarding the usefulness of SMA Doppler measurements in detecting neonates at risk for NEC. We used the Preferred Reporting Items for Systematic reviews and Meta-Analyses guidelines, and we included studies which reported the following Doppler ultrasonography indices: peak systolic velocity, end-diastolic velocity, time average mean velocity, differential velocity, pulsatility index (PI) and resistive index. Eight studies were eligible for inclusion in the meta-analysis. Evidence suggested that, during the first postnatal day, neonates who developed NEC had a significantly higher peak systolic velocity (mean difference of 2.65 cm/s (95% confidence interval [CI] 1.23, 4.06, overall effect Z=3.66, P<0.001)), higher PI (mean difference of 1.52 (95% CI 0.00, 3.04, Z=1.96, P=0.05)) and higher resistive index (mean difference of 1.09 (95% CI 0.59, 1.60, Z=4.24, P<0.001)), compared to neonates who did not develop NEC. However, our findings do not support a strong association between the Doppler ultrasound indices and development of NEC at the time of disease onset. This meta-analysis suggests that first postnatal day SMA Doppler parameters, namely peak systolic velocity, PI and resistive index, are higher in neonates who develop NEC. On the other hand, the aforementioned indices are of uncertain significance once the diagnosis of NEC has been established.

[PMID: 37331187 DOI: 10.1016/j.nutres.2023.05.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2023] [Revised: 05/07/2023] [Accepted: 05/20/2023] [Indexed: 06/20/2023]
Abstract
Evidence supports that growth trajectory during infancy has a major impact on body composition. We aimed to examine body composition in children born small for gestational age (SGA) or appropriate for gestational age (AGA) adjusted for postnatal growth velocity. We enrolled 365 children, 75 SGA and 290 AGA, aged 7 to 10 years, examining anthropometrics, skinfold thickness, and body composition using bioelectrical impedance analysis. Growth velocity was defined as rapid or slow (weight gain > or <0.67 z-scores, respectively). Gestational age, sex, delivery mode, gestational diabetes, hypertension, nutrition, exercise, parental body mass index (BMI), and socioeconomic status were considered. At a mean of 9 years of age, SGA compared with AGA-born children, had significantly lower lean mass. BMI was negatively associated with SGA status (beta = 0.80, P = .046), after adjusting for birth weight, delivery mode, and breastfeeding. The lean mass index was negatively associated with SGA status (beta = 0.39, P = .018), after adjusting for the same factors. SGA-born participants with slow growth velocity had significantly lower lean mass in comparison to AGA-born counterparts. SGA-born children with rapid compared with those with slow growth velocity had significantly higher absolute fat mass. BMI was negatively associated with a slow postnatal growth pattern (beta = 0.59, P = .023), and the lean mass index was negatively associated with a slow postnatal growth pattern (beta = 0.78, P = .006), after adjusting for the same factors. In conclusion, SGA-born children presented a lower lean mass in comparison to AGA-born counterparts, whereas BMI and lean mass index were negatively associated with slow postnatal growth velocity.

Effects of Fremanezumab on Psychiatric Comorbidities in Difficult-to-Treat Patients with Chronic Migraine: Post Hoc Analysis of a Prospective, Multicenter, Real-World Greek Registry. J Clin Med 2023; 12:4526. [PMID: 37445560 DOI: 10.3390/jcm12134526] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/02/2023] [Revised: 07/03/2023] [Accepted: 07/04/2023] [Indexed: 07/15/2023] Open
Abstract
OBJECTIVE this post hoc analysis aimed to evaluate the efficacy of fremanezumab in difficult-to-treat chronic migraine (CM) patients with and without psychiatric comorbidities (PCs), mainly anxiety and/or depression. METHODS We assessed data from CM patients with and without PCs who failed at least 3 preventives and eventually received at least 3 consecutive monthly doses of fremanezumab 225 mg. Outcomes included the crude response (≥50% reduction in monthly headache days (MHDs)) rates to fremanezumab from the baseline to the last clinical follow-up. The changes in MHDs; MHDs of moderate/greater severity; monthly days with intake of abortive medication; and the proportion of patients' changing status from with PCs to decreased/without PCs were also compared. Disability and quality of life (QOL) outcomes were also assessed. RESULTS Of 107 patients enrolled, 65 (60.7%) had baseline PCs. The percentage of patients with (n = 38/65; 58.5%) and without (n = 28/42; 66.6%) PCs that achieved a ≥50% reduction in MHDs with fremanezumab was comparable (p = 0.41), whereas MHDs were significantly reduced (difference vs. baseline) in both patients with PCs (mean -8.9 (standard error: 6.8); p < 0.001) and without PCs (-9.8 (7.5); p < 0.001). Both groups experienced significant improvements in all other efficacy, disability, and QOL outcomes at comparable rates, including in MHD reduction. A significant proportion of fremanezumab-treated patients with baseline PCs de-escalated in corresponding severities or even reverted to no PCs (28/65; 43.1%) post-fremanezumab. CONCLUSIONS fremanezumab appears to be effective as a preventive treatment in difficult-to-treat CM patients with and without PCs while also being beneficial in reducing the severity of comorbid anxiety and/or depression.

Abstract
Data regarding the nutritional management of preterm small for gestational age (SGA) infants are scarce. In the recent report of ESPGHAN, the recommended energy for very preterm infants during hospitalization has been increased, yet this may not fit the needs of all preterm infants. It is important to distinguish fetal growth-restricted (FGR) infants from constitutional SGA infants, as well as preterm SGA from preterm AGA infants, since they may have different nutritional needs. Preterm FGR infants, and specifically infants < 29 weeks' gestation, accumulate nutrient deficits due to intrauterine malnutrition, prematurity, morbidities, delayed initiation of feeding, and feeding intolerance. Therefore, these infants may need more aggressive nutrition for optimal catch-up growth and neurologic development. However, a balance should be kept between optimal and excessive catch-up growth, since the combination of intrauterine malnutrition and excessive postnatal growth has been linked with later adverse metabolic consequences. Furthermore, multiple gestation is often complicated by FGR and prematurity. There is controversy in the definition of FGR in multiple gestations, and it should be noted that FGR in multiple gestation usually differs etiologically from FGR in singletons. The aim of this review is to summarize existing knowledge regarding the nutritional needs of preterm FGR and FGR infants of multiple gestation.

Predictors of Response to Fremanezumab in Migraine Patients with at Least Three Previous Preventive Failures: Post Hoc Analysis of a Prospective, Multicenter, Real-World Greek Registry. J Clin Med 2023; 12:jcm12093218. [PMID: 37176658 PMCID: PMC10179256 DOI: 10.3390/jcm12093218] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2023] [Revised: 04/24/2023] [Accepted: 04/28/2023] [Indexed: 05/15/2023] Open
Abstract
OBJECTIVE To define, in a real-world population of patients with high-frequency episodic (HFEM) or chronic migraine (CM), the predictive role of socio-demographic or phenotypic profiling of responders to fremanezumab. PATIENTS AND METHODS Two-hundred and four adult fremanezumab-treated patients with either HFEM or CM, who failed to at least three preventive treatments, provided data at baseline on several individual socio-demographic and phenotypic variables. These variables were analyzed for their ability to independently predict the response (50-74% response rates) or super-response (≥ 75% response rates) to fremanezumab. Patients were followed from 3-18 months of fremanezumab exposure. RESULTS The main finding to emerge from univariate analyses was that three baseline socio-demographic/clinical variables, i.e., age group 41-70 years (p = 0.02); female gender (p = 0.03); patients with HFEM (p = 0.001), and three clinical phenotypic variables, i.e., strict unilateral pain (p = 0.05); pain in the ophthalmic trigeminal branch (p = 0.04); and the "imploding" quality of pain (p = 0.05), were significantly related to fremanezumab response. However, in multivariate analysis, only HFEM (p = 0.02), the presence of strict unilateral (p = 0.03), and pain location in the ophthalmic trigeminal branch (p = 0.036) were independently associated with good fremanezumab response. Allodynia (p = 0.04) was the only clinical predictive variable of super-responsiveness to fremanezumab. CONCLUSIONS A precise phenotypic profiling with identification of pain characteristics consistent with peripheral and/or central sensitization might reliably predict the responsiveness to fremanezumab in migraine prophylaxis.

Abstract
Antibiotics are the most frequently prescribed drugs in neonatal intensive care units (NICUs) due to the severity of complications accompanying neonatal sepsis. However, antimicrobial drugs are often used inappropriately due to the difficulties in diagnosing sepsis in the neonatal population. The reckless use of antibiotics leads to the development of resistant strains, rendering multidrug-resistant pathogens a serious problem in NICUs and a global threat to public health. The aim of this narrative review is to provide a brief overview of neonatal sepsis and an update on the data regarding indications for antimicrobial therapy initiation, current guidance in the empirical antimicrobial selection and duration of therapy, and indications for early discontinuation.

Abstract
AIM To evaluate the predictive value of perinatal factors and neurodevelopmental evaluation in the emotional and behavioural outcomes in preterm-born children at 7-9 years of age. METHODS We evaluated the Strengths and Difficulties Questionnaire (SDQ) extended score at 8.2 ± 0.2 years, among 70 preterm-born children (32 early and 38 moderately preterms) with a previous Bayley-III neurodevelopmental evaluation. RESULTS Early compared to moderately preterms had a higher total SDQ (12 compared to 8, p = 0.031), and emotional symptoms score (4 compared to 3, p = 0.022); no significant differences were recorded in abnormal/borderline-scored children between the two groups. The total SDQ and emotional symptoms scores were significantly correlated with gestational age, birth weight, perinatal factors and the cognitive and motor Bayley-III scores. Early prematurity was associated with the total SDQ score (beta 2.09, 95% CI 1.32, 3.87), and the score of emotional symptoms (beta 1.70, 95% CI 1.38, 2.19), after adjusting for sex, neonatal sepsis and the existence of an older sibling. CONCLUSION Prematurity, birth weight, perinatal factors and the cognitive and motor Bayley-III scores were significantly associated with the total SDQ and the emotional symptoms score, in preterm-born children.

Abstract
Wolfram syndrome 1 (WS1) is a rare autosomal recessive neurodegenerative disease caused by mutations in WFS1 and WFS2 genes that produce wolframin, a protein involved in endoplasmic reticulum calcium homeostasis and cellular apoptosis. Its main clinical features are diabetes insipidus (DI), early-onset non-autoimmune insulin-dependent diabetes mellitus (DM), gradual loss of vision due to optic atrophy (OA) and deafness (D), hence the acronym DIDMOAD. Several other features from different systems have been reported such as urinary tract, neurological, and psychiatric abnormalities. In addition, endocrine disorders that can appear during childhood and adolescence include primary gonadal atrophy and hypergonadotropic hypogonadism in males and menstrual cycle abnormalities in females. Further, anterior pituitary dysfunction with deficient GH and/or ACTH production have been described. Despite the lack of specific treatment for the disease and its poor life expectancy, early diagnosis and supportive care is important for timely identifying and adequately managing its progressive symptoms. The current narrative review focuses on the pathophysiology and the clinical features of the disease, with a special emphasis on its endocrine abnormalities that appear during childhood and adolescence. Further, therapeutic interventions that have been proven to be effective in the management of WS1 endocrine complications are discussed.

Efficacy and safety of fremanezumab for migraine prophylaxis in patients with at least three previous preventive failures: Prospective, multicenter, real-world data from a Greek registry. Eur J Neurol 2023; 30:1435-1442. [PMID: 36773011 DOI: 10.1111/ene.15740] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2023] [Accepted: 02/02/2023] [Indexed: 02/12/2023]
Abstract
OBJECTIVE To prospectively assess the efficacy and safety of fremanezumab for migraine prophylaxis in patients with failure of at least three previous preventive treatments. Changes in disability as quality-of-life outcomes after fremanezumab treatment were also examined. METHODS Two hundred and four patients with either high-frequency EM (HFEM) or chronic migraine (CM), who attained at least three consecutive monthly sessions with fremanezumab 225 mg and otherwise met the inclusion criteria, were included in the study. The crude response (at least 50% reduction in monthly headache days [MHD]) rates to fremanezumab were assessed. Scores in the following efficacy outcomes were then compared from baseline to the last efficacy evaluation follow-up: (i) MHD, (ii) monthly days with moderate/severe peak headache intensity, and (iii) monthly days with intake of abortive medication. The disability was evaluated with the Migraine Disability Assessment; the quality of life (QOL) status was assessed with the Headache Impact-6 Test, and the EQ-5D questionnaire. RESULTS In the majority of HFEM cases (n = 81/97; 83.5%) and CM patients (n = 67/107; 62.6%), fremanezumab proved effective in reducing the MHDs by at least 50% and was associated with clinically meaningful improvement in all other efficacy variables. The migraine-related disability experienced by our patients decreased and their QOL increased. We recorded just 36 cases reporting mild adverse events, including pain, rash or pruritus (n = 26), flu-like symptoms (n = 8), and hair loss (n = 2). CONCLUSION With our prospective results, we provide further real-world data to support the favorable benefit/risk profile of fremanezumab in the prophylaxis of both HFEM and CM.

Is small for gestational age status independently correlated with body composition during childhood? Eur J Pediatr 2023; 182:661-668. [PMID: 36445515 PMCID: PMC9899173 DOI: 10.1007/s00431-022-04723-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/12/2022] [Revised: 09/13/2022] [Accepted: 11/17/2022] [Indexed: 11/30/2022]
Abstract
This study aims to examine if small for gestation age (SGA) status is correlated with alterations in body composition at prepuberty, independently of other factors, comparing SGA-born children with appropriate for gestational age (AGA)-born children. We examined anthropometrics, waist circumference, body mass index (BMI), six skinfold thickness, and body composition using the method of bioelectrical impedance in 636 children aged 7 to 10 years. We also considered age, gender, birth mode, mother's age, prepregnancy weight, weight gain during pregnancy, social status, parental BMI, type of feeding, and daily exercise. We examined 636 children at a mean age of 9 years: 106 SGA-born and 530 AGA-born children. SGA as compared to AGA-born children had a lower BMI z-score (0.26 ± 0.89 kg/cm2 vs 0.46 ± 0.84 kg/cm2, p < 0.050) and a lower lean mass, although that was not statistically significant (24.0 ± 6.6 kg vs 25.6 ± 6.4 kg, p < 0.100). SGA-born children presented no difference in waist circumference or fat mass in comparison to children born AGA. Logistic regression analysis revealed a strong independent negative association between SGA status and BMI (beta = - 2.33, OR = 0.70 p = 0.019) and SGA status and lean mass (beta = - 2.43, OR = 0.95 p = 0.010). Conclusion: Our findings suggest that SGA-born children had a lower BMI as compared to AGA-born subjects, whereas SGA status was negatively associated with BMI and lean mass. What is Known: • Deviant birth weight for gestation has been associated with an increased risk of childhood adiposity. • Evidence remains scarce on whether small for gestational age status affects body composition and obesity later in childhood. What is New: • Among school-aged children, small for gestational age subjects had a lower body mass index as compared to appropriate for gestational age counterparts, whereas small for gestational age status was negatively associated with body mass index and lean mass. • A meticulous observation is needed during childhood in children born with deviant birth weight.

The trends for the "trend toward significance" in the pediatric literature. Eur J Pediatr 2023; 182:937-940. [PMID: 36459228 PMCID: PMC9899178 DOI: 10.1007/s00431-022-04746-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/20/2022] [Revised: 11/08/2022] [Accepted: 11/28/2022] [Indexed: 12/05/2022]
Abstract
UNLABELLED Purpose This study is to examine whether the term "trend toward statistical significance" is used to describe statistically nonsignificant results in biomedical literature. We examined articles published in five high-impact pediatric journals, including The Lancet Child & Adolescent Health, The Journal of Pediatrics, Early Human Development, Frontiers in Pediatrics, and BMC Pediatrics to identify manuscripts where a "trend" was used to describe a statistically nonsignificant result, from January 2020 to December 2021, and, furthermore, for The Journal of Pediatrics, Early Human Development, and BMC Pediatrics from January 2010 to December 2011. We detected that a "trend toward significance" was used to describe a statistically nonsignificant result at least once in 146 articles (2.7%) during the period between 2020 and 2021 and in 97 articles (4.0%) during the period between 2010 and 2011. We found no significant difference in the proportion of published articles with inappropriate use of "trend" across journals belonging to the first quartile of impact compared to the second quartile or across journals publishing under the subscription model or open access policy compared to journals publishing solely under the open access policy, in any period. The overall proportion of the inappropriate use of "trend" declined significantly between 2010 and 2011 to 2020 and 2021 (p = 0.002, RR 0.66 95% CI 0.51-0.86). CONCLUSION "Trend" statements were sporadically used to describe statistically nonsignificant results across pediatric literature. The inappropriate use of "trend" to describe almost significant differences could be misleading, and "trend" should be reserved only when a specific statistical test for trend has been performed, or in relation to appropriate scientific definitions. WHAT IS KNOWN •Previously, researchers have reported inappropriate use of "trend" in articles across anaesthesia or major oncology journals. •In many cases, hypothesized results that are close but not lower than the statistical significance threshold are emphasized as "almost" significant. WHAT IS NEW •"Trend" statements were sporadically used to describe statistically nonsignificant results across pediatric literature. •Inappropriate use of "trend" was similar in journals with a subscription model compared to those having an open access policy and decreased within a 10-year period.

Abstract
BACKGROUND Stressful events during infancy may predispose to the development of functional gastrointestinal disorders (FGIDs) in childhood. AIMS To evaluate the association of necrotizing enterocolitis (NEC) with childhood FGIDs. METHODS We conducted a study, comparing 29 children of eight to ten years with a history of NEC with 58 children with no history of NEC. Subjects were assessed for FGIDs, based on Rome-III criteria. RESULTS Among 29 subjects with NEC, 17 had surgical and 12 conservative NEC. Subjects with surgically, or conservatively managed NEC developed FGIDs at a significantly higher proportion, as compared to children with no history of NEC, later in childhood (41%, 33%, and 13% respectively, p = 0.033). Functional constipation was the most frequently identified disorder (35%, 33%, and 7% respectively). A significant association was detected between FGIDs and the history of perinatal stress (p = 0.049), NEC (p = 0.011), and the surgical management of NEC (p = 0.015). CONCLUSIONS Our study suggests that there is a potential association between NEC and FGIDs later in childhood with functional constipation being the most frequently identified disorder.

Abstract
Food allergy is a common health problem in childhood since its prevalence was estimated to range from 6. 5 to 24.6% in European countries. Recently, a lot of research has focused on the impact of breastfeeding on oral tolerance induction. Since it was found that breast milk contains immunologically active food antigens, it would be very helpful to clarify the factors of antigen shedding that promotes oral tolerance. This narrative review aimed to summarize the latest evidence from experimental and human studies regarding allergen characteristics in human milk that may influence oral tolerance induction. A literature search in PubMed, MEDLINE, and Google Scholar was conducted. The diet of the mother was found to have a direct impact on allergen amount in the breastmilk, while antigens had different kinetics in human milk between women and depending on the antigen. The mode of antigen consumption, such as the cooking of an antigen, may also affect the allergenicity of the antigen in human milk. The dose of the antigen in human milk is in the range of nanograms per milliliter; however, it was found to have a tolerogenic effect. Furthermore, the presence of antigen-specific immunoglobulins, forming immune complexes with antigens, was found more tolerogenic compared to free allergens in experimental studies, and this is related to the immune status of the mother. While examining available data, this review highlights gaps in knowledge regarding allergen characteristics that may influence oral tolerance.

Abstract
AIMS We aimed to evaluate the effects of maternal diabetes on neonatal iron status, measuring erythrocyte indices including hemoglobin, hematocrit, reticulocytes, mean corpuscular volume (MCV), percent (%) hypochromia, ferritin, and additionally mean reticulocyte hemoglobin content (MCHr) as an early marker of iron deficiency, and examine the association between neonatal MCHr, red cell indices, and ferritin. MATERIALS AND METHODS We conducted a hospital-based prospective cohort study in a tertiary neonatal unit of a University Hospital from 2018 to 2020. We enrolled 126 maternal-infant pairs of mothers whose pregnancy was associated with diabetes and 74 maternal-infant pairs from uncomplicated pregnancies. Erythrocyte indices were analyzed within the first twelve hours after birth. Erythrocyte parameters were compared between infants of the diabetes and the non-diabetic group. We examined the correlation of the neonatal MCHr with perinatal characteristics, including gestation, birth weight, maternal body mass index, the erythrocytic indices, maternal diabetes, maternal obesity, prematurity, small-for-gestational-age status, maternal preeclampsia, and maternal anemia. Finally, we evaluated the discordance between neonatal MCHr and neonatal ferritin. RESULTS Infants of the diabetes group had a significantly lower MCHr (32.6 pg vs. 34.2 pg, p=0.003) compared with infants of uncomplicated pregnancies. Neonatal MCHr was significantly correlated with maternal hypochromia (r=-0.237, p=0.004) and neonatal MCV (r=0.674, p<0.001). Neonatal MCHr was significantly associated with maternal diabetes [standardized coefficients 0.21, 95% confidence interval (CI) 0.05-0.58, p=0.003) and maternal preeclampsia (standardized coefficients 0.17, 95% CI 0.02-0.92, p=0.019), after adjusting for maternal anemia, maternal obesity, prematurity, and small-for-gestational-age status. Those results were consistent also when analyzing maternal-infant pairs with pre-existing diabetes, and maternal-infant pairs with gestational diabetes. There was significant discordance between neonatal MCHr and neonatal ferritin (p=0.001). CONCLUSIONS MCHr was significantly lower in infants of mothers whose pregnancy was associated with diabetes compared with infants of non-diabetic mothers and correlated with neonatal and maternal red cell indices of iron deficiency. Since there was significant discordance between neonatal MCHr and ferritin during the first postnatal day, it is possible that MCHr could be used as a screening test for iron deficiency, especially in infants.

Abstract
OBJECTIVE Chorioamnionitis and fetal inflammatory response syndrome (FIRS) are significant risk factors for early onset sepsis (EOS). Recently, the use "Intrauterine Inflammation or Infection or both" or triple I has been proposed, classifying cases into an isolated maternal fever, suspected triple I, or confirmed chorioamnionitis. Evidence suggests that the association between suspected chorioamnionitis and confirmed histological chorioamnionitis (HCA) is not consistent, as well as the impact of HCA on the development of EOS.We aimed to evaluate the association between suspected chorioamnionitis and HCA, the impact of HCA on EOS, and the effect of antepartum antibiotic prophylaxis on EOS. METHODS We retrospectively reviewed the medical records of all infants admitted to our institution, between 2017 and 2018, with a diagnosis of chorioamnionitis. We recorded the clinical evidence of chorioamnionitis, the histologic report of the placenta, the maternal and neonatal data, the neonatal inflammatory markers including C-reactive protein (CRP), and the incidence of EOS. The impact of antepartum antibiotic prophylaxis on the infants' CRP and EOS was calculated, and the logistic regression model was performed to estimate the association of confirmed HCA with EOS, while controlling for FIRS stage, gestation age, birth weight, maternal fever, foul-smelling amniotic fluid, and prolonged rupture of membranes. RESULTS During the study period, a total of 266 infants were identified; 81 (30%) infants had a confirmed HCA (HCA-present cases), and 185 (70%) infants were diagnosed with suspected triple I (HCA-absent cases). Antepartum antibiotics had been commenced in a significantly higher proportion in HCA-present cases (46%) in comparison to 14% of HCA-absent cases (p < .001). HCA-present infants were of significantly lower gestation (31.6 ± 4weeks versus 33.3 ± 4weeks, p = .004), and birth weight (1826 ± 840 g versus 2092 ± 849 g, p = .019), they had a significantly higher rate of clinical symptoms (31% versus 6%, p < .001), and a higher CRP at birth and 24 h (1.4 ± 1.5 mg/dL versus 0.3 ± 0.2 mg/dL, p < .001, and 2.1 ± 2.3 mg/dL versus 0.4 ± 0.6 mg/dL, p < .001, respectively). All HCA-present cases had evidence of FIRS; 43% were stage I, 25% stage II, and 32% were FIRS stage III. A significantly higher proportion of HCA-present infants were diagnosed with EOS (46% as compared to 6%, p < .001). The antepartum antibiotic administration was related to a significantly lower CRP at birth and 24 h only in HCA-present cases, albeit not with any reduction ιn EOS incidence. HCA was significantly associated with EOS (RR 3.18, 95% CI 2.81-5.18, p < .001). After adjusting for perinatal factors, the presence of HCA (OR 7.89, 95% CI 1.19-23.34, p = .032) and an advanced FIRS stage (OR 10.35, 95% CI 4.23-25.32, p < .001) were significantly associated with EOS. CONCLUSIONS Amongst infants with suspected chorioamnionitis, the diagnosis is partially supported by histological confirmation, and that is more prominent in pregnancies of a lower gestation. The presence of HCA and an advanced FIRS stage predispose to an increased risk of EOS after adjusting for other perinatal and neonatal factors. The antepartum prophylaxis against intra-amniotic infection was related to a significantly lower CRP in HCA-present cases.

Abstract
PURPOSE The purpose of this review is to provide an update on ophthalmological manifestations of Noonan Syndrome (NS). Emerging evidence has suggested that NS patients may present with a wide spectrum of ocular characteristics. Detailed investigation of genotype has revealed the diversity of related gene mutations. The potential association of genetic basis with clinical expressivity of phenotype remains a challenging aspect of this issue. METHODS A literature search was performed in PubMed; we have analyzed prospective and retrospective cohort studies, case reports, and reference lists of retrieved articles until February 2021. We identified all papers referring to NS ocular manifestations referring to genotype and phenotype characteristics. RESULTS A comprehensive update on ocular manifestations of NS patients indicates significant evidence for variability of genotype and phenotype features. Ophthalmologic features of NS are characterized by a wide spectrum of abnormalities; external ocular malformations, distortions of refraction, alignment, motilily, anterior and posterior ocular segment and visual impairment. Currently, a variety of pathogenic mutations in patients with NS have been investigated, while the nature of the genetic variants may determine expressivity. Albeit it remains a clinical diagnosis with variation in the progress of each NS phenotype. Although the available evidence that is needed to establish genotype-phenotype correlation as predicting factor in clinical practice is limited, it could aid risk assessment and patient management. CONCLUSION A review of the existing literature sheds light on the ocular characteristics of NS. The current article discusses notable aspects of key publications on the topic, highlights the importance of the potential genotype-phenotype correlation in clinical practice, and proposes the need for further future research.

A systematic review indicates an association between birth weight and body fat in childhood. Acta Paediatr 2021; 110:2023-2039. [PMID: 33682216 DOI: 10.1111/apa.15834] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/19/2020] [Revised: 02/28/2021] [Accepted: 03/03/2021] [Indexed: 12/14/2022]
Abstract
AIM To summarise the existing evidence regarding the body fat of small or large for gestation subjects, evaluated from birth up to 18 years of age. METHODS The PRISMA guidelines were adopted for the current systematic review, including studies having evaluated body fat with bioelectrical impedance analysis, air displacement plethysmography, dual-energy X-ray absorptiometry or magnetic resonance imaging. RESULTS A total of 31 studies was included. The balance of evidence suggests that small for gestation infants have decreased fat mass at birth; postnatally they experience increased adiposity. In the long term, however, the evidence is inconclusive, since some studies suggest that foetal-restricted children with increased catch-up growth are at increased risk of fat accumulation, whereas other studies suggest a neutral or even negative association. Large for gestation infants have increased fat mass at birth, but in the long term, they have a lower body fat ratio, especially when they develop a catch-down growth. CONCLUSION Some studies suggested that foetal-restricted children with increased catch-up growth are at increased risk of later adiposity, while other studies suggested a neutral or negative association. Given that the evidence is inconclusive, further studies are warranted. Large for gestation subjects have lower body fat when they develop catch-down growth.

Abstract
BACKGROUND Evidence examining the association of over-hydration during early life with haemodynamically significant patent ductus arteriosus (hsPDA) and other morbidities is limited. Our aim was to evaluate the association of fluid overload during the first postnatal day with hsPDA and common neonatal morbidities such as bronchopulmonary dysplasia in preterm infants. METHODS A retrospective cohort study was conducted enrolling infants ≤30 weeks' gestation and ≤1500 grams' birth weight, admitted to a tertiary Neonatal Unit. We calculated the fluid balance and we estimated the incidence of infants with fluid overload ≥5% during the first postnatal day, evaluating any possible correlation with hsPDA. RESULTS 103 infants of 27.3±1.6 weeks' gestation and 1009±225 grams' birth weight were enrolled; of whom 32 (31%) were diagnosed with HsPDA. Fluid overload during the first postnatal day was recorded in 42 infants (41%). Infants with fluid overload were diagnosed with hsPDA in 48%, compared to 20% of infants without fluid overload (p=0.004). No differences were recorded in the development of bronchopulmonary dysplasia or survival. Fluid overload of ≥5% was significantly correlated with hsPDA (r=0.37, p=0.003) and had an independent contribution to the risk of hsPDA (OR 1.17, 95% CI 1.05-1.58), irrespective of other perinatal factors. CONCLUSIONS In preterm infants, fluid overload ≥5% is significantly associated with hsPDA, therefore, fluid management during the first postnatal day should be closely regulated.

Abstract
OBJECTIVE C-reactive protein (CRP) is one of the most extensively used biomarkers in the investigation of early-onset sepsis (EOS). Current evidence suggests the normal kinetics of serum CRP should be considered when evaluating infants for presumable EOS. The current study aimed to evaluate the CRP kinetics, and to establish percentiles in a cohort of term and near-term infants with no evidence of confirmed or clinical EOS. METHODS We retrospectively reviewed the medical records of all neonates ≥34 weeks' gestation screened for presumable EOS, from January until December 2019. We also recorded the clinical management, the blood culture, serial CRP, and white blood cell count analysis of each infant. All infants that received antibiotics for confirmed or presumed EOS were excluded from the analysis. RESULTS During the study period, 145 infants were detected; 109 (75%) term and 36 (25%) preterm. Term infants had significantly higher median values of CRP at all time points in comparison to preterm infants. Term infants presented a significant rise of CRP at 24 and 36 h, with a peak at 24 h (median 4 (range 1-12) mg/L). Preterm infants had a significant rise of CRP at 24 but not at 36 h, with a peak at 24 h (median 3 (range 1-9) mg/L). In term infants, the 90th percentile of CRP at 24 h was 10.80 mg/L and the 97th percentile was 12.00 mg/L. In preterm infants, the 90th percentile of CRP at 24 h was 7.60 mg/L and the 97th percentile was 8.00 mg/L. CONCLUSIONS Term and near-term asymptomatic infants had a rise in CRP during the first days of life. Term infants had a more pronounced CRP response in comparison to preterm infants.

Abstract
BACKGROUND Applying customized centiles may improve the accuracy of detecting small for gestational age (SGA) infants; however, the evidence is inconclusive whether adjusted centiles are more sensitive in identifying infants at increased risk of morbidity. We aimed to examine the validity of customized centiles in a Greek cohort and evaluate their performance compared to population-based centiles in predicting infants at risk of increased morbidity. METHODS We prospectively recorded the neonatal and maternal characteristics of singleton, low-risk, term infants over a year. Infants were defined as SGA if their birth weight was under the tenth centile, classified both by population-based centiles and customized centiles, adjusted for maternal and innate factors. We performed a comparative analysis utilizing linear regression analysis and calculating the receiver operating characteristics (ROC) curves. RESULTS Overall 657 infants were identified. Population-based centiles detected 42 (6 %) SGA infants, while customized centiles 80 (12 %). Perinatal morbidity was associated with an odds ratio of 1.02 with customized centiles [95 % confidence interval (CI): 1.01-1.04] and with an odds ratio of 1.02 with population-based centiles (95 % CI: 1.02-1.02). In predicting perinatal morbidity, no significant difference was detected between customized centiles [area under the ROC curve 0.773 (95 % CI: 0.699-0.847)] and population-based centiles [area under the ROC curve 0.737 (95 % CI: 0.662-0.813)] (p =0.272). CONCLUSIONS Customized centiles provided increased accuracy in comparison to the population-based centiles in detecting SGA term infants. However, customized centiles had no better impact on predicting a poor perinatal outcome. HIPPOKRATIA 2020, 24(3): 133-137.

Abstract
Objective To examine cerebral oxygenation and perfusion in small for gestational age (SGA) compared with appropriate for gestational age (AGA) neonates during the first postnatal week, and to investigate any association with neurodevelopmental outcomes at 24-36 months of age. Methods A prospective matched case-control study was conducted evaluating cerebral oxygenation and perfusion, using near-infrared spectroscopy (NIRS), between SGA and AGA neonates, during the first postnatal week. A neurodevelopmental assessment with Bayley-III was performed at 24-36 months of age. Results Forty-eight SGA and 48 AGA neonates of similar gestation (32.8 ± 2.1 vs. 32.5 ± 1.9) were enrolled. On the first postnatal day, the cerebral oxygenation was equal between SGA and AGA neonates (71 ± 7% vs. 72 ± 8%); however, in the subgroup analysis, males had higher oxygenation compared to female SGA neonates (73 ± 7% vs. 69 ± 7%, P = 0.04). Cerebral perfusion was significantly higher in SGA neonates on the first postnatal day (1.4 ± 0.6 vs. 1.1 ± 0.5, P = 0.04), but this difference was diminished on subsequent measurements. There were no significant differences between the SGA and AGA infants regarding the composite cognitive, communication and motor index scores. The length of mechanical ventilation and late-onset sepsis were significant risk factors affecting the cognitive and communication composite index scores, respectively. Conclusion Cerebral oxygenation was equal between SGA and AGA neonates, while cerebral perfusion was transiently increased in SGA neonates during the first postnatal day. There was no significant association of cerebral oxygenation and perfusion with neurodevelopmental outcomes.

Abstract
OBJECTIVE The aim of the Integrated Family Delivered Care (IFDC) programme was to improve infant health outcomes and parent experience through education and competency-based training. DESIGN In collaboration with veteran parents' focus groups, we created an experienced co-designed care bundle including IFDC mobile application, which together with staff training programme comprised the IFDC programme. Infant outcomes were compared with retrospective controls in a prepost intervention analysis. MAIN OUTCOME MEASURES The primary outcome measure was the length of stay (LOS). RESULTS Between April 2017 and May 2018, 89 families were recruited; 37 infants completed their entire care episode in our units with a minimum LOS >14 days. From a gestational age (GA) and birth weight-matched retrospective cohort, 57 control infants were selected. Data were also analysed for subgroup under 30 weeks GA (n=20).Infants in the IFDC group were discharged earlier: median corrected GA (36+0 (IQR 35+0-38+0) vs 37+1 (IQR 36+3-38+4) weeks; p=0.003), with shorter median LOS (41 (32-63) vs 55 (41-73) days; p=0.022). This was also evident in the subgroup <30 weeks GA (61 (39-82) vs 76 (68-84) days; p=0.035). Special care days were significantly lower in the IFDC group (30 (21-41) vs 40 (31-46); p=0.006). The subgroup of infants (<30 weeks) reached full suck feeding earlier (median: 47 (37-76) vs 72 (66-82) days; p=0.006). CONCLUSION This is the first reported study from a UK tertiary neonatal unit demonstrating significant benefits of family integrated care programme. The IFDC programme has significantly reduced LOS, resulted in the earlier achievement of full enteral and suck feeds.

Abstract
BACKGROUND Neonatal sepsis has been associated with poor neurodevelopmental outcome, however the evidence regarding the exact mechanism of the inflammation to the developing neonatal brain are inconclusive. AIMS To investigate association between cerebral oxygenation during neonatal sepsis and neurodevelopmental outcome. STUDY DESIGN Follow-up assessment of a previously described prospective case-control study. SUBJECTS A cohort of late preterm (34-37 weeks' gestation) and preterm (<34 weeks' gestation) infants with sepsis and healthy controls, evaluated at 18-24 months of corrected gestational age with Bayley-III Scales for Infant and Toddler Development (BSID-III). OUTCOME MEASURES To evaluate the association between cerebral tissue oxygenation index (cTOI) and fractional tissue oxygen extraction (FTOE), measured with near-infrared spectroscopy, during sepsis and the composite cognitive and motor index scores. RESULTS Thirty-one infants with blood culture confirmed neonatal sepsis and thirty-five controls were recruited. The cerebral oxygenation was significantly lower in septic neonates, compared to controls (61 ± 7 compared to 72 ± 5; p < 0.001). Infants with sepsis had significantly lower cognitive and motor index scores and higher proportion of suboptimal cognitive (16% compared to 3%, p = 0.045) and motor (16% compared to none, p = 0.008) index score. The low mean cTOI and FTOE noted in septic infants were significantly associated with worse cognitive and motor composite index scores. CONCLUSIONS Infants with lower cerebral oxygenation during neonatal sepsis are at increased risk of worse cognitive and motor scores in the neurodevelopmental assessment.

Abstract
BACKGROUND Adequate nutrition is essential for optimal neurodevelopment to preterm infants. Our aim was to evaluate the impact of caloric deprivation on Bayley-III scales performance at 18-24 months of corrected age, in a cohort of preterm infants. METHODS We prospectively enrolled infants with gestational age <30 weeks and birth weight <1500 g. Apart from a whole cohort analysis, we performed a subgroup analysis between infants received inadequate calories (<85 Kcal/kg/day) during the first two weeks of age, compared to a standard nutrition group. All infants underwent a Bayley-III assessment at 18-24 months of corrected age. RESULTS From the 63 preterm infants analysed, 25% had caloric deprivation compared to 75% with adequate nutrition. Caloric deprived infants were of lower gestational age and birth weight, and received a lower amount of enteral feeding during the first 14 days of age. There were no differences between the two groups regarding the common neonatal co-morbidities. Caloric deprived infants had significantly lower composite index scores at 18-24 months of corrected age. Caloric deprivation, late onset sepsis, necrotizing enterocolitis, and bronchopulmonary dysplasia were significant risk factors of neurodevelopmental impairment. CONCLUSIONS Several neonatal factors affect the neurodevelopmental outcome of preterm infants, and nutrition may pose an important role.

Abstract
BACKGROUND Although inhaled nitric oxide (iNO) therapy in term infants with pulmonary hypertension (PHT) has demonstrated definite benefit, the use of iNO in preterm infants remains inconclusive. AIMS To evaluate the impact of iNO treatment in premature infants with acute PHT. STUDY DESIGN Retrospective cohort. SUBJECTS Infants < 34 weeks' gestational age, admitted during 2010-2016 to two neonatal units, having treated with iNO for confirmed PHT. A positive response was defined by FiO2 reduction ≥20% within 3-h post iNO initiation. Early PHT was defined when developed within the first 72 h of age. OUTCOME MEASURES The primary outcome was the evaluation of the acute response to iNO administration. Secondary outcomes included the comparison of neonatal characteristics and outcomes between positive and negative responders, and early or late PHT infants. RESULTS Of the 55 infants of our cohort, 39 (71%) had a positive response to iNO administration. No differences noted regarding bronchopulmonary dysplasia, intraventricular haemorrhage or other morbidities; however, positive responders had significantly higher survival rate in overall (77 vs 21%, p = 0.001) and within early PHT subgroup (74 vs 33%, p = 0.044). Regression analysis revealed that oligohydramnios (OR 2.834, 95%CI 1.652-6.070) and early PHT (OR 1.953, 95%CI 1.377-2.930) were significantly related with a positive response. CONCLUSIONS Preterm infants with confirmed acute PHT respond in significant proportion to the iNO administration, especially in the background of oligohydramnios or the development of early PHT.

Abstract
AbstractDecompressive craniectomy (DC) is considered a rescue therapy in patients with traumatic brain injury (TBI) with increased intracranial pressure (ICP). In this retrospective study, we examined the impact of craniectomy on ICP in children with severe TBI and their neurological outcome. A total of 14 patients were enrolled. Peak ICP was significantly lower (31 ± 2.9 to 19 ± 4.6, p < 0.001) and minimum cerebral perfusion pressure (CPP) higher (41 ± 10.5 to 58 ± 11.4, p < 0.001) postcraniectomy. The survival rate was 71%. However, 57% of our cohort had a poor neurological outcome at 6 months postinjury. In conclusion, although rescue DC was effective in controlling ICP and CPP, the long-term neurological outcome remained poor.

Abstract
Objective Neonates with sepsis have increased risk of cerebral injury. Our aim was to evaluate cerebral oxygenation in septic neonates using near-infrared spectroscopy. Study Design A prospective study was designed enrolling neonates with sepsis, as defined by the International Consensus Conference of Pediatric Sepsis criteria and matched controls. Three cerebral half-hourly measurements were performed during the first, third, and seventh day of the episode and the values of tissue oxygenation index (TOI) and fractional tissue oxygen extraction (FTOE) were compared between the two groups. Result The study population consisted of 50 septic and 44 control neonates with similar characteristics. No differences on TOI and FTOE were recorded in the first and third day. However, on the seventh day, septic neonates had significantly decreased oxygenation (62.7 ± 7 vs. 71.4 ± 4.4%, p < 0.001) and increased oxygen extraction (0.35 ± 0.07 vs. 0.27 ± 0.05, p < 0.001), irrespectively of the severity of the infection. Conclusion Although septic neonates have normal cerebral oxygenation in the first and third day of the sepsis, they present decreased cerebral oxygenation in the seventh day independently of the infection severity.

Effectiveness of 7.5% hypertonic saline in children with severe traumatic brain injury. J Crit Care 2016; 38:52-56. [PMID: 27838440 DOI: 10.1016/j.jcrc.2016.10.014] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2016] [Revised: 10/15/2016] [Accepted: 10/17/2016] [Indexed: 11/25/2022]
Abstract
PURPOSE Hyperosmolar therapies aim at controlling increased intracranial pressure (ICP) in patients with traumatic brain injury (TBI). The aim of this study was to evaluate the effect of 7.5% hypertonic saline (HTS) on ICP and cerebral perfusion pressure (CPP) in children with severe TBI. MATERIALS AND METHODS Medical records of patients 14 years or younger with severe TBI, admitted in the pediatric intensive care unit of "Aghia Sophia" Children's Hospital, Athens, Greece, during 2009 to 2015, and received HTS apart from mannitol were retrospectively reviewed. The ICP and CPP pre-HTS and 30, 60, and 120 minutes post-HTS infusion were evaluated. Furthermore, the presence of adverse effects, the long-term neurological outcome, and survival were recorded. RESULTS Twenty-nine patients requiring in total 136 HTS infusions were analyzed. The ICP was significantly reduced and CPP elevated at 30, 60, and 120 minutes postinfusion; and furthermore, postadministration ICP and CPP were predominantly within acceptable limits. No significant adverse effects were recorded and most of the patients survived, however, one third had severe neurological impairment at 6 months postinjury. CONCLUSIONS In our study, 7.5% HTS infusion as a second-tier osmotic therapy was associated with significant reduction of ICP and increase of CPP in children with severe TBI.

Significant reduction of central line-associated bloodstream infection rates in a tertiary neonatal unit. Am J Infect Control 2016; 44:485-7. [PMID: 26717871 DOI: 10.1016/j.ajic.2015.10.040] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/20/2015] [Revised: 10/26/2015] [Accepted: 10/30/2015] [Indexed: 10/22/2022]
Abstract
To evaluate the effectiveness of a quality initiative in reducing central line-associated bloodstream infections (CLABSIs) in our neonatal intensive care unit, we designed a prospective study (January 2012-September 2013) estimating CLABSI incidence before and after our implementation. CLABSI rates were significantly decreased after our intervention, from 12 cases per 1,000 central vascular catheter (CVC) days during the preinterventional period to 3.4 cases per 1,000 CVC days during the postinterventional period (P = .004).

Abstract
To evaluate the consistency of the Hammersmith Infant Neurological Examination scores of very-low-birth-weight infants at 6 and 12 months of age and its correlation to cranial ultrasonography findings, we designed a prospective study between January 2005 and January 2008, in the tertiary Neonatal Unit of Aristotle University of Thessaloniki, Greece. All infants enrolled had a cranial ultrasonography performed at term. Preterm infants born at <32 weeks gestation with a birth weight <1500 g were eligible for the study. One hundred seventy-four infants were finally enrolled; out of those, 46 (26%) had an optimal score at 6 and 76 (44%) at 12 months of age. Mean global scores were 61 and 69 at 6 and 12 months, respectively. The Hammersmith Infant Neurological Examination score significantly increased between 6 and 12 months, equally in all ultrasonography groups. The presence of cystic periventricular leukomalacia was associated to lower scores and neurologic impairment.

Abstract
BACKGROUND Oxidative stress, characterized by the excretion of pre-oxidative and anti-oxidative proteases, has a key role in the pathogenesis of bronchopulmonary dysplasia (BPD). One of the many host anti-oxidant enzymes is glutathione-S-transferase P1 (GSTP1), with three polymorphic alleles having been identified: homozygous ile, heterozygous ile/val and homozygous val isomorph. The aim of this study was to examine the genetic predisposition to BPD in the GSTP1 polymorphisms. METHODS A prospective case-control study was carried out in the 2nd Neonatal Intensive Care Unit of Aristotle University in Thessaloniki, Greece during 2008. The genetic polymorphisms of GSTP1 in 28 preterms <32 weeks gestational age (GA) with BPD compared to 74 controls (33 preterms without BPD and 41 healthy terms) were examined. RESULTS The homozygous ile isomorph was predominant in all groups (preterms with BPD: 82%, preterms without BPD: 70%, healthy terms: 78%), followed by the heterozygous ile/val (14%, 18% and 20% respectively) and the homozygous val isomorph (4%, 12% and 2% respectively). The homozygous ile isomorph was also identified in the majority of preterms with mild (80%), moderate (100%) and severe (73%) BPD. The GSTP1 genetic distribution did not differ between the groups and GSTP1 polymorphisms were not associated with the severity of BPD. CONCLUSIONS This study could not confirm an association between GSTP1 polymorphisms and the development of BPD or the severity of the disease.
