Combined gestational age and serum fucose for early prediction of risk for bronchopulmonary dysplasia in premature infants

ObjectiveAs the predominant complication in preterm infants, Bronchopulmonary Dysplasia (BPD) necessitates accurate identification of infants at risk and expedited therapeutic interventions for an improved prognosis. This study evaluates the potential of Monosaccharide Composite (MC) enriched with environmental information from circulating glycans as a diagnostic biomarker for early-onset BPD, and, concurrently, appraises BPD risk in premature neonates.Materials and methodsThe study incorporated 234 neonates of ≤32 weeks gestational age. Clinical data and serum samples, collected one week post-birth, were meticulously assessed. The quantification of serum-free monosaccharides and their degraded counterparts was accomplished via High-performance Liquid Chromatography (HPLC). Logistic regression analysis facilitated the construction of models for early BPD diagnosis. The diagnostic potential of various monosaccharides for BPD was determined using Receiver Operating Characteristic (ROC) curves, integrating clinical data for enhanced diagnostic precision, and evaluated by the Area Under the Curve (AUC).ResultsAmong the 234 neonates deemed eligible, BPD development was noted in 68 (29.06%), with 70.59% mild (48/68) and 29.41% moderate-severe (20/68) cases. Multivariate analysis delineated several significant risk factors for BPD, including gestational age, birth weight, duration of both invasive mechanical and non-invasive ventilation, Patent Ductus Arteriosus (PDA), pregnancy-induced hypertension, and concentrations of two free monosaccharides (Glc-F and Man-F) and five degraded monosaccharides (Fuc-D, GalN-D, Glc-D, and Man-D). Notably, the concentrations of Glc-D and Fuc-D in the moderate-to-severe BPD group were significantly diminished relative to the mild BPD group. A potent predictive capability for BPD development was exhibited by the conjunction of gestational age and Fuc-D, with an AUC of 0.96.ConclusionA predictive model harnessing the power of gestational age and Fuc-D demonstrates promising efficacy in foretelling BPD development with high sensitivity (95.0%) and specificity (94.81%), potentially enabling timely intervention and improved neonatal outcomes.

Quality improvement in the golden hour for premature infants: a scoping review

Background and objectiveEvidence-based research has shown that golden hour quality improvement (QI) measures can improve the quality of care and reduce serious complications of premature infants. Herein, we sought to review golden hour QI studies to evaluate the impact on the outcome of preterm infants.MethodsA comprehensive literature search was conducted in PubMed, Embase, Cochrane Library, and SinoMed databases from inception to April 03, 2023. Only studies describing QI interventions in the golden hour of preterm infants were included. Outcomes were summarized and qualitative synthesis was performed.ResultsTen studies were eligible for inclusion. All studies were from single centers, of which nine were conducted in the USA and one in Israel. Seven were pre-post comparative studies and three were observational studies. Most included studies were of medium quality (80%). The most common primary outcome was admission temperatures and glucose. Five studies (n = 2308) reported improvements in the admission temperature and three studies (n = 2052) reported improvements in hypoglycemia after QI. Four studies (n = 907) showed that the incidence of bronchopulmonary dysplasia (BPD) was lower in preterm infants after QI: 106/408 (26.0%) vs. 122/424(29.5%) [OR = 0.68, 95% CI 0.48–0.97, p = 0.04].ConclusionsOur study showed that the golden hour QI bundle can improve the short-term and long-term outcomes for extremely preterm infants. There was considerable heterogeneity and deficiencies in the included studies, and the variation in impact on outcomes suggests the need to use standardized and validated measures. Future studies are needed to develop locally appropriate, high-quality, and replicable QI projects.

Common Complications in Infants Born to Diabetic Mothers

Infants of diabetic mothers are at increased risk of complications. There is always a need for more research on this topic to look for complications and make strategies for prevention and management. Objectives: To determine the frequency of complications in infants born to diabetic mothers. Methods: This descriptive study was done at the Department of Pediatrics, Molvi Ameer Shah Memorial Hospital, Peshawar from 1st January 2022 to 31st December 2022. A total of 150 infants born to diabetic mothers were enrolled after written informed consent and frequencies of complications were noted. Data were analyzed using SPSS 24.0. Results: The mean age of the patients was 3.08 ± 1.7 days. The minimum age was 1 day, and the maximum was 7 days. The mean age of the mother was 26.9 ± 4.07 years. The mean gestational age was 36.9 ± 1.4 weeks. The mean duration of diabetes was 7.6 ± 1.14 years. The mean HbA1c level was 7.27 ± 2.41. There were 38% males and 62% female. Adequate diabetic control was present in 24.7% of patients while 75.3% had poor diabetic control. The most common complication was hypoglycemia in 24.7% followed by Macrosomia in 22.7%, prematurity in 20%, hyperbilirubinemia 11.3%, hypocalcemia in 10.7% and polycythemia in 10.7% patients. Conclusions: Most common complication was hypoglycemia followed by macrosomia, prematurity, hyperbilirubinemia, hypocalcemia, and polycythemia. However, due to its limited sample size, the results may not be generalizable.

Early metabolic markers as predictors of respiratory complications in preterm infants with bronchopulmonary dysplasia

BackgroundBronchopulmonary dysplasia (BPD), a common complication of premature birth, exerts considerable impact on the respiratory health of infants. This study aimed to identify the role of plasma metabolites in predicting respiratory outcomes in BPD-afflicted infants. MethodsThis was a case-control study including 15 BPD premature infants and 15 gestational age and birth weight matched no-BPD preterm infants. Plasma samples, obtained at 36 weeks postmenstrual age (PMA), were subjected to a comprehensive analysis of over 300 metabolites using liquid chromatography-tandem mass spectrometry (LC-MS/MS). The respiratory outcomes of the infants were collected with the first 2 years of corrected postnatal age. ResultsThe analysis revealed a significant upregulation of urea and downregulation of nine metabolites in BPD infants, including oxalacetic acid, cis-aconitic acid, itaconic acid, betaine, L-asparagine, L-alanine, picolinic acid, inositol, and purine (p < 0.05). These metabolites primarily pertained to the citrate cycle (TCA cycle), glyoxylate and dicarboxylate metabolism, and alanine, aspartate, and glutamate metabolism. Furthermore, seven metabolites demonstrated substantial predictive capacity for respiratory readmissions within the first two years of corrected postnatal age, achieving an area under curve (AUC) exceeding or equal to 0.8. These included chenodeoxycholic acid, dehydrolithocholic acid, glucaric acid, D-glucuronic acid, gamma-glutamylvaline, mevalonic acid, and 3-ureidopropionic acid. ConclusionsThis study identified ten distinct plasma metabolites at 36 weeks PMA that differentiate BPD infants from their non-BPD counterparts, implicating three major metabolic pathways. Additionally, seven metabolites showed strong predictive value for heightened risk of respiratory readmission within two years, underscoring their potential utility in clinical prognostication and management strategies for BPD.

Evaluation of surgical treatment strategies and outcome for cerebral arachnoid cysts in children and adults

ObjectiveThe best treatment strategies for cerebral arachnoid cysts (CAC) are still up for debate. In this study, we present CAC management, outcome data, and risk factors for recurrence after surgical treatment, focusing on microscopic/endoscopic approaches as compared to minimally invasive stereotactic procedures in children and adults.MethodsIn our single-institution retrospective database, we identified all patients treated surgically for newly diagnosed CAC between 2000 and 2022. Microscopic/endoscopic surgery (ME) aimed for safe cyst wall fenestration. Stereotactic implantation of an internal shunt catheter (STX) to drain CAC into the ventricles and/or cisterns was used as an alternative procedure in patients aged ≥ 3 years. Treatment decisions in favor of ME vs. STX were made by interdisciplinary consensus. The primary study endpoint was time to CAC recurrence (TTR). Secondary endpoints were outcome metrics including clinical symptoms and MR-morphological analyses. Data analysis included subdivision of the total cohort into three distinct age groups (AG1, < 6 years; AG2, 6–18 years; AG3, ≥ 18 years).ResultsSixty-two patients (median age 26.5 years, range 0–82 years) were analyzed. AG1 included 15, AG2 10, and AG3 37 patients, respectively. The main presenting symptoms were headache and vertigo. In AG1 hygromas, an increase in head circumference and thinning of cranial calvaria were most frequent. Thirty-five patients underwent ME and 27 STX, respectively; frequency did not differ between AGs. There were two (22.2%) periprocedural venous complications in infants (4- and 10-month-old) during an attempt at prepontine fenestration of a complex CAC, one with fatal outcome in a 10-month-old boy. Other complications included postoperative bleeding (2, 22.2%), CSF leaks (4, 44.4%), and meningitis (1, 11.1%). Overall, clinical improvement and significant volume reduction (p = 0.008) were seen in all other patients; this did not differ between AGs. Median follow-up for all patients was 25.4 months (range, 3.1–87.1 months). Recurrent cysts were seen in 16.1%, independent of surgical procedure used (p = 0.7). In cases of recurrence, TTR was 7.9 ± 12.7 months. Preoperative ventricular expansion (p = 0.03), paresis (p = 0.008), and age under 6 years (p = 0.03) were significant risk factors for CAC recurrence in multivariate analysis.ConclusionsIn patients suffering from CAC, both ME and STX can improve clinical symptoms at low procedural risk, with equal extent of CAC volume reduction. However, in infants and young children, CAC are more often associated with severe clinical symptoms, stereotactic procedures have limited use, and microsurgery in the posterior fossa may bear the risk of severe venous bleeding.

Manifestazioni cutanee anulari e lupus eritematoso neonatale

Neonatal lupus erythematosus (NLE) is a rare immune-mediated disorder due to the pas- sage of maternal anti-Ro/SSA and anti-La/SSB antibodies through the placenta to the foe- tus and newborn. Major manifestations include cardiac anomalies and skin lesions, while hepatic and haematological abnormalities are observed in a minority of cases. The most serious complication is congenital heart block, usually already occurring in the prenatal period (second or third trimester of pregnancy). Cutaneous lupus is the typical manifestation of NLE, characterized by transient and generally photosensitive annular erythematous le- sions, preferentially localized on the face, scalp or periocular region, and less commonly observed on the trunk and extremities. Due to its benign and transient course, no treatment is required. Prophylaxis with hydroxychloroquine in pregnant women testing positive for autoantibodies and/or with a previously affected child may reduce the risk of cardiac and/or cutaneous complications in newborns and infants. The article reports the case of a two-day-old newborn showing a widespread cutaneous rash with erythematous “stepped” patches compatible with annular erythema, localized on their upper and lower limbs, as well as on the anterior surface of their trunk. Obstetric history, which revealed the mother being affected with Sjogren Syndrome and performing hydroxychloroquine prophylaxis, led to the NLE diagnostic suspicion, later confirmed by the detection of specific antibodies (anti-SSA/Ro60 and SSA/Ro52). Although the prognosis of cutaneous NLE is generally favourable, any coexisting and potential life-threatening complications, including haema- tological and cardiological abnormalities, should be ruled out.

Retinopathy of prematurity screening: prevalence and risk factors of ophthalmic complications in non-treated preterm infants.

Retinopathy of prematurity (ROP) is a vision-threatening disease of premature infants. Practice guidelines recommend that all infants screened for ROP receive follow-up eye examinations to screen for ophthalmic complications.1 The purpose of this study was to identify risk factors for the development of strabismus, amblyopia, high refractive error, and cataracts among ROP-screened, non-treated infants. Retrospective single-centre study of ROP-screened, non-treated premature infants with ophthalmic follow-up. Clinical variables were screened for association with ocular findings at follow-up. Multivariable logistic regression was used to determine the risk factors associated with ocular findings. 309 patients were seen for follow-up at 0.97 (0.69) [mean (SD)] years after neonatal intensive care unit (NICU) discharge. Strabismus was predicted by occipitofrontal circumference (OFC) z-score at NICU discharge (OR 0.61; 95% CI [0.42, 0.88]; p = 0.008), intraventricular haemorrhage (IVH) grade III or IV (OR 3.18; 95% CI [1.18, 8.54]; p = 0.02), and exclusive formula feeding at NICU discharge (OR 2.20; 95% CI [1.07, 4.53]; p = 0.03). Significant predictors of amblyopia were OFC z-score at discharge (OR 0.55; 95% CI [0.31, 0.96]; p = 0.03) and necrotising enterocolitis (NEC) (OR 6.94; 95% CI [1.38, 35.00]; p = 0.02). NEC was a significant risk factor for high refractive error (OR 7.27; 95% CI [1.39, 37.94]; p = 0.02). Among premature infants screened but not treated for ROP, severe IVH, NEC, low OFC z-score, and exclusive formula feeding at NICU discharge were risk factors for ocular morbidity. These findings affirm the value of ophthalmic follow-up for all ROP-screened infants, particularly those with the identified risk factors.

Analysis of clinical characteristics and risk factors of postoperative complications in infants with early-onset necrotizing enterocolitis after enterostomy

Objective: To investigate the clinical characteristics of children with early-onset necrotizing enterocolitis (NEC) undergoing enterostomy and analyze the risk factors for postoperative complications. Methods: Retrospective analysis was conducted on the clinical data (perinatal conditions, clinical characteristics, clinical outcomes, etc.) of NEC patients who underwent enterostomy at Beijing Children's Hospital from May 2016 to May 2023. The patients were divided into two groups based on the age of onset: an early-onset enterostomy group (<14 days) and a late-onset enterostomy group (≥14 days). Furthermore, the children with NEC were categorized into complication group and non-complication group based on whether there were complications after enterostomy. The differences in clinical data between these groups were analyzed, and the clinical characteristics of children with early-onset NEC and enterostomy were summarized. Multivariate logistic regression model was employed to analyze the risk factors for postoperative complications in NEC children with enterostomy. Results: A total of 68 cases were enrolled, including 43 cases in the early-onset enterostomy group [26 males and 17 females, aged (6.5±3.0) days] and 25 cases in the late-onset enterostomy group [15 males and 10 females, aged (21.0±3.0) days]. There were 28 cases (17 males and 11 females), age [M (Q1, Q3)] 9 (5, 14) days in the complication group and 33 cases (22 males and 11 females), aged of 14 (6, 21) days in the non-complication group. Compared to the late-onset enterostomy group, the early-onset enterostomy group had significantly higher rates of intraventricular hemorrhage [30.2% (13/43) vs 8.0% (2/25)], hemodynamically significant patent ductus arteriosus [37.2% (16/43) vs 12.0% (3/25)], mechanical ventilation≥72 hours after birth [39.5% (17/43) vs 16.0% (4/25)], stage Ⅲ NEC [(69.8% (30/43) vs 40.0% (10/25)], extensive NEC [27.9% (12/43) vs 8.0% (2/25)], and short-term postoperative complications [56.8% (21/37) vs 29.2% (7/24)] (all P<0.05).Multivariate logistic regression model analysis revealed that residual length of proximal small intestine was a protective factor for postoperative complications after enterostomy in NEC infants (OR=0.764, 95%CI: 0.648-0.901, P=0.001), but stage Ⅲ NEC was a risk factor (OR=1.042, 95%CI: 1.004-5.585, P=0.017). Conclusions: The incidence of postoperative complications is high, and the prognosis is poor in children with early-onset NEC enterostomy. The residual length of proximal enterostomy is a protective factor for postoperative complications of NEC enterostomy, but stage Ⅲ NEC is a risk factor.

Background. Congenital Zika Syndrome presents a significant public health concern, particularly due to its association with severe neurological complications in infants born to maternal infected with the Zika virus during pregnancy. This article offers a comprehensive overview of the risks, complications, and preventive measures associated with Zika virus infection during pregnancy. Methods. A thorough literature search was conducted, encompassing studies, case reports, and clinical observations related to neurological complications in infants with congenital Zika syndrome. The review focuses on elucidating the intricate relationship between maternal Zika virus infection and the subsequent neurological challenges faced by newborns. Results. The neurological impacts of congenital Zika syndrome are multifaceted, ranging from the well-documented microcephaly to less explored manifestations such as brain abnormalities, ventriculomegaly, intracranial calcifications, seizures, and sensory impairments. Additionally, joint and limb contractures contribute to the complexity of congenital Zika syndrome-related neurological deficits. This narrative review synthesizes current knowledge on the subject, shedding light on the diverse ways in which Zika virus infection during pregnancy can affect the developing fetal nervous system. Conclusion. Understanding the intricate neurological complications associated with congenital Zika syndrome is crucial for healthcare practitioners, researchers, and policymakers. This review provides a comprehensive overview of the current state of knowledge, emphasizing the need for continued research, surveillance, and public health interventions to mitigate the impact of the Zika virus on maternal and child health.

Cerebellar injury in preterm infants less than 28 weeks gestational age.

Cerebellar injury is one of the perinatal complications in preterm infants. Recent studies have highlighted the effect of perinatal complications on neurological morbidity. We investigated the perinatal risk factors and morbidity for cerebellar injury in extremely premature infants. This retrospective cohort study included 285 infants born between April 2009 and December 2020 at gestational age <28 weeks at our institution. The infants were divided into two groups based on magnetic resonance imaging findings: those with and without cerebellar injury. We performed a statistical analysis of the perinatal background and short-term morbidity of the two groups. Significant differences (p < 0.05) were observed between the groups with respect to the perinatal background, especially gestational weeks, birthweight, and hemoglobin values at birth. In the short-term morbidity, significant differences (p < 0.05) were observed in the incidence of respiratory distress syndrome, chronic lung disease, hydrocephalus, severe intraventricular hemorrhage (IVH), and cerebellar hemorrhage. Extensive cerebellar lesions, such as cerebellar agenesis or global cerebellar hypoplasia, accounted for 11 of the 22 cases of cerebellar injury; seven of the 11 cases had severe IVH in addition to cerebellar hemorrhage. Gestational age was significantly lower in the cerebellar injury group. The combination of severe IVH and cerebellar hemorrhage may promote cerebellar injury.

Central line-associated bloodstream infection related with umbilical vein catheterization and peripherally inserted central catheter in preterm infants: a meta-analysis and systematic review

BACKGROUND Central line-associated bloodstream infection (CLABSI) is a serious complication in preterm infants undergoing catheterization, including umbilical vein catheterization (UVC) and peripherally inserted central catheter (PICC) placement. This study aimed to compare the occurrence rate of CLABSI in preterm infants associated with UVC and PICC.&#x0D; METHODS We conducted a systematic review and meta-analysis of studies published from 2000 to 2023 using a random effects model from 3 databases (PubMed, ScienceDirect, and Google Scholar). This study was registered with PROSPERO (CRD42023416471).&#x0D; RESULTS Of 10 articles included in the systematic review, 2 were randomized controlled trials, 3 were prospective studies, and the rest were retrospective. A total of 3,962 UVCs and 2,922 PICCs were incorporated in the meta-analysis. The incidence rate of CLABSI in the UVC group was lower than that in the PICC group (1.23 versus 3.03 per 1,000 catheter days). However, the odds of developing CLABSI for infants with a UVC compared to those with a PICC were not statistically significant (odds ratio: 0.88, 95% confidence interval: 0.54–1.42).&#x0D; CONCLUSIONS UVCs had a lower incidence rate of CLABSI than PICCs. Therefore, additional prospective studies are required to confirm these results.

Predictive and Diagnostic Values of Systemic Inflammatory Indices in Bronchopulmonary Dysplasia.

Bronchopulmonary dysplasia (BPD) is the most common respiratory complication in preterm infants, and there is a lag in the diagnosis of BPD. Inflammation is a vital pathogenic factor for BPD; we aim to evaluate the predictive and diagnostic values of systemic inflammatory indices in BPD. Between 1 January 2019 and 31 May 2023, the clinical data of 122 premature infants with a gestational age of <32 weeks in the Department of Neonatology, the Affiliated Huai'an No. 1 People's Hospital of Nanjing Medical University, were retrospectively collected and classified into non-BPD (n = 72) and BPD (n = 50) groups based on the National Institute of Child Health and Human Development 2018 criteria. To compare the general characteristics of each group, we identified the independent risk variables for BPD using multivariate logistic regression analysis, compared the systemic inflammatory indices at birth, 72 h, 1 week, 2 weeks, and 36 weeks postmenstrual age (PMA), and constructed the receiver operating characteristic curves of neutrophil-to-lymphocyte ratio (NLR) diagnosis of BPD at different time points. ① The independent risk factors for BPD in preterm infants were birth weight, small for gestational age, and days of oxygen therapy (all p < 0.05). ② At 72 h and 1 week after birth, the serum NLR of the BPD group was higher than for the non-BPD group (p < 0.05). Furthermore, the neutrophil count (N), NLR, monocyte-to-lymphocyte ratio (MLR), systemic immune-inflammation index, systemic inflammation response index (SIRI), and pan-immune-inflammation value of infants with BPD were higher than the non-BPD group at 3 weeks after birth (p < 0.05). Moreover, at 36 weeks of PMA, the serum N, NLR, MLR, and SIRI of BPD infants were higher than those of non-BPD infants (p < 0.05). ③ The NLR of infants with and without BPD gradually increased after birth, reaching a peak at 72 h and 1 week, respectively. At 3 weeks postnatal, the NLR had the highest predictive power for BPD, with an area under the curve (AUC) of 0.717 (p < 0.001); the sensitivity was 56% and specificity was 86.1%. In addition, the NLR at 36 weeks of PMA exhibited some diagnostic value for BPD. The AUC was 0.693 (p < 0.001), the sensitivity was 54%, and specificity was 83.3%. At 3 weeks after birth and 36 weeks of PMA, some systemic inflammation indices (like N, NLR, SIRI) of preterm infants with BPD have specific predictive and diagnostic values; these indices may help the management of high-risk preterm infants with BPD.

Pregnancy and infant outcomes following SARS-CoV-2 infection in pregnancy during delta variant predominance – Surveillance for Emerging Threats to Pregnant People and Infants

SARS-CoV-2 infection in pregnancy is associated with an increased risk of adverse birth outcomes such as preterm birth, stillbirth, and maternal and infant complications. Previous research suggests an increased risk of severe COVID-19 illness and stillbirth in pregnant people during delta variant predominance in 2021; however, those studies did not assess timing of infection during pregnancy, and few of them described COVID-19 vaccination status. Using a large population-based cohort, this study compared pregnancy and infant outcomes and described demographic and clinical characteristics of pregnant people with SARS-CoV-2 infection prior to and during the delta variant period. This retrospective cohort analysis included persons with confirmed SARS-CoV-2 infection in pregnancy from 6 US jurisdictions reporting to the Surveillance for Emerging Threats to Pregnant People and Infants Network. Data were collected through case reports of polymerase chain reaction-positive pregnant persons and linkages to birth certificates, fetal death records, and immunization records. We described clinical characteristics and compared frequency of spontaneous abortion (<20 weeks of gestation), stillbirth (≥20 weeks), preterm birth (<37 weeks), small for gestational age, and term infant neonatal intensive care unit admission between the time periods of pre-delta and delta variant predominance. Study time periods were determined by when variants constituted more than 50% of sequences isolated according to regional SARS-CoV-2 genomic surveillance data, with time periods defined for pre-delta (March 3, 2020-June 25, 2021) and Delta (June 26, 2021-December 25, 2021). Adjusted prevalence ratios were estimated for each outcome measure using Poisson regression and were adjusted for continuous maternal age, race and ethnicity, and insurance status at delivery. Among 57,563 pregnancy outcomes, 57,188 (99.3%) were liveborn infants, 65 (0.1%) were spontaneous abortions, and 310 (0.5%) were stillbirths. Most pregnant persons were unvaccinated at the time of SARS-CoV-2 infection, with a higher proportion in pre-delta (99.4%) than in the delta period (78.4%). Of those with infections during delta and who were previously vaccinated, the timing from last vaccination to infection was a median of 183 days. Compared to pre-delta, infections during delta were associated with a higher frequency of stillbirths (0.7% vs 0.4%; adjusted prevalence ratio, 1.55; 95% confidence interval, 1.14-2.09) and preterm births (12.8% vs 11.9%; adjusted prevalence ratio, 1.14; 95% confidence interval, 1.07-1.20). The delta period was associated with a lower frequency of neonatal intensive care unit admission (adjusted prevalence ratio, 0.74; 95% confidence interval, 0.67-0.82) than in the pre-delta period. During the delta period, infection during the third trimester was associated with a higher frequency of preterm birth (adjusted prevalence ratio, 1.41; 95% confidence interval, 1.28-1.56) and neonatal intensive care unit admission (adjusted prevalence ratio, 1.21; 95% confidence interval, 1.01-1.45) compared to the first and second trimester combined. In this US-based cohort of persons with SARS-CoV-2 infection in pregnancy, the majority were unvaccinated, and frequencies of stillbirth and preterm birth were higher during the delta variant predominance period than in the pre-delta period. During the delta period, frequency of preterm birth and neonatal intensive care unit admission was higher among infections occurring in the third trimester vs those earlier in pregnancy. These findings demonstrate population-level increases of adverse fetal and infant outcomes, specifically in the presence of a COVID-19 variant with more severe presentation.

Post-COVID19 pulmonary complications in infants – clinical-imaging approaches

Introduction. COVID-19 infection affects people of any age or gender. It was found that children up to 6 months of age have a major risk of developing a severe form of the infection. Contemporary diagnostic imaging methods of high sensitivity, such as lung CT, allow to establish the degree of lung damage, the volume and the sequelae arising from enduring the COVID-19 infection. The long-term consequences of the COVID-19 infection are still being researched. Pneumonia in the infection of COVID-19 can lead to the long-term development pulmonary fibrosis, atelectasis, bronchiectasis. Case report. The 5-month-old boy is admitted to the Pneumology Clinic with dyspnea, tachypnea, acrocyanosis, agitation, food refusal. It is known from the anamnesis that at the age of 4 months the child suffered a severe form of the COVID-19 infection. Non-contrast lung CT was performed which suggests fibro-atelectatic changes in both lungs, predominantly in the apical and basal segments. Conclusions. Infants show an increased vulnerability to develop bronchopulmonary changes after COVID-19. The case is suggestive from a clinical point of view, emphasizing the connection between the form, the evolution of the disease, and the consequences arising from the COVID-19 infection. Fibrotic pulmonary evolutionary changes are suggestive of SARS-CoV-2 virus infection.

OBSTETRICAL AND NEONATAL OUTCOMES AMONG PREGNANCIES COMPLICATED BY HYPERPARATHYROIDISM: SYSTEMATIC REVIEW

Background: Primary hyperparathyroidism (PHPT) is a relatively common disorder of the parathyroid glands, causing skeletal, renal, and cardiac complications. As etiological features of PHPT, single adenoma, hyperplasia, carcinoma, and familiar causes (MEN multiple endocrine neoplasia, FHH familiar hypocalciuric hypercalcemia, hyperparathyroidismjaw tumor syndrome) are presented. Primary hyperparathyroidism in pregnancy has an incidence of 1, which is underestimated due to the plethora of undiagnosed cases. The aim: This study aims to show about obstetrical and neonatal outcomes among pregnancies complicated by hyperparathyroidism. Methods: By comparing itself to the standards set by the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) 2020, this study was able to show that it met all of the requirements. So, the experts were able to make sure that the study was as up-to-date as it was possible to be. For this search approach, publications that came out between 2013 and 2023 were taken into account. Several different online reference sources, like Pubmed and SagePub, were used to do this. It was decided not to take into account review pieces, works that had already been published, or works that were only half done. Result: In the PubMed database, the results of our search brought up 10 articles, whereas the results of our search on SagePub brought up 60 articles. The results of the search conducted for the last year of 2013 yielded a total 2 articles for PubMed and 14 articles for SagePub. The result from title screening, a total 1 articles for PubMed and 10 articles for SagePub. In the end, we compiled a total of 7 papers. We included five research that met the criteria. Conclusion: Pregnancy complicated by PHPT may lead to serious maternal and infant complications. MDT consultation ensures timely diagnosis, comprehensive treatment for the patients and better pregnancy outcomes.

The effect of skin-to-skin contact on early initiation of breastfeeding among women in Vietnam

AimTo describe prevalence of early initiation of breastfeeding and associated factors among Vietnamese mothers. MethodsA self-administered questionnaire was used to survey 1812 mothers whose infants were aged 0 to less than 30 months in multi-center Vietnam. Multivariate logistic regression was performed to identify factors associated independently with early initiation of breastfeeding. ResultsPrevalence of early initiation of breastfeeding was 57.2 % and this prevalence was higher in female infants compared with male infants (p = 0.004). Factors associated with increased odds of early initiation of breastfeeding include female infants (aOR: 1.33; 95%CI: 1.06 to 1.68) living in urban areas (aOR: 1.34, 95%CI: 1.05 to 1.71), giving birth in private hospitals (aOR: 1.94, 95%CI: 1.25 to 3.03), vaginal birth (aOR: 1.70, 95%CI: 1.34 to 2.16). Factors associated with decreased odds of early initiation of breastfeeding include higher educational level, mother's weight gain during pregnancy, and infant complication at birth. Compared with mothers who had not experienced skin-to-skin contact with their babies, the prevalence of early initiation of breastfeeding was higher in mothers who experienced <15 min (aOR: 2.03, 95%CI: 1.32 to 3.14), 15–90 min (aOR: 6.33, 95%CI: 4.11 to 9.76), and >90 min (aOR: 10.98, 95%CI: 6.79 to 17.75). ConclusionFocusing on modifiable factors should be a key priority to help improve early initiation of breastfeeding practice.

Mesenchymal stromal/stem cells and bronchopulmonary dysplasia.

Bronchopulmonary dysplasia (BPD) is a common complication in preterm infants, leading to chronic respiratory disease. There has been an improvement in perinatal care, but many infants still suffer from impaired branching morphogenesis, alveolarization, and pulmonary capillary formation, causing lung function impairments and BPD. There is an increased risk of respiratory infections, pulmonary hypertension, and neurodevelopmental delays in infants with BPD, all of which can lead to long-term morbidity and mortality. Unfortunately, treatment options for Bronchopulmonary dysplasia are limited. A growing body of evidence indicates that mesenchymal stromal/stem cells (MSCs) can treat various lung diseases in regenerative medicine. MSCs are multipotent cells that can differentiate into multiple cell types, including lung cells, and possess immunomodulatory, anti-inflammatory, antioxidative stress, and regenerative properties. MSCs are regulated by mitochondrial function, as well as oxidant stress responses. Maintaining mitochondrial homeostasis will likely be key for MSCs to stimulate proper lung development and regeneration in Bronchopulmonary dysplasia. In recent years, MSCs have demonstrated promising results in treating and preventing bronchopulmonary dysplasia. Studies have shown that MSC therapy can reduce inflammation, mitochondrial impairment, lung injury, and fibrosis. In light of this, MSCs have emerged as a potential therapeutic option for treating Bronchopulmonary dysplasia. The article explores the role of MSCs in lung development and disease, summarizes MSC therapy's effectiveness in treating Bronchopulmonary dysplasia, and delves into the mechanisms behind this treatment.

Cerebral and intestinal oxygen saturation of different volumes of red blood cell transfusion in preterm infants

ObjectivesThe purpose of this study was to investigate and compare the effects of 20 ml/kg and 15 ml/kg red blood cell transfusion (RBCT) on cerebral and intestinal tissue oxygenation, the number of administered transfusions, and neonatal complications in premature infants with anemia. MethodsThis prospective, randomized, partially blinded observational study investigated anemic neonates of gestational age < 32 weeks (Registration ID: ChiCTR 1,900,026,672). The infants were randomly assigned to receive 15 or 20 ml/kg red blood cell transfusion. Cerebral and intestinal tissue oxygen saturation (cer rSO2 and int rSO2) were collected 2 h before transfusion, 2, 4, 6, 12, 24, and 48 h after the beginning of transfusion by Near-infrared spectroscopy (NIRS). We also collected vital signs including heart rate (HR), peripheral oxygen saturation (SpO2), and mean arterial blood pressure (MABP) 2 h before infusion, 2 h, and 6 h after the beginning of transfusion. Then we analyzed and compared regional oxygen saturation(rSO2), fractional tissue oxygen extraction (FTOE), and other outcome readouts (blood transfusion numbers, changes in hematocrit and hemoglobin, hospitalization days, HR, SpO2, MABP, and complications) between the two groups. The intraindividual comparisons of the above readouts before transfusion and those after transfusion were also evaluated within each group. Result73 newborns received 20 ml/kg (large volume group) and 78 newborns received 15 ml/kg transfusion (small volume group). There was no significant difference in cer rSO2, int rSO2, Cerebral fractional tissue oxygen extraction (cFTOE), and intestinal fractional tissue oxygen extraction (iFTOE) between the two groups. rSO2, MABP, and SpO2 increased; HR, cFTOE, and iFTOE decreased following transfusion in both groups. The transfusion number of the large volume group is significantly less than that of the small volume group (1.9 ± 0.3 vs. 2.6 ± 0.9, p < 0.01) and hospitalization days were also less than those in the low volume group (44.3 ± 8.2 vs. 47.6 ± 9.8, p < 0.05). The increases in hematocrit and hemoglobin were higher in the large volume group than those in small volume (hematocrit increment (%),10.7 ± 4.2 vs. 10.1 ± 5.9, p = 0.015; Hb concentration after blood transfusion (g/L) 132.3 ± 11.1 vs. 127.4 ± 15.4, p = 0.028). ConclusionAfter the transfusion, cer rSO2 and int rSO2 increased significantly, FTOE decreased and vital signs improved in both the 15 ml/kg and 20 ml/kg groups, and these changes were not significantly different between the two groups. However, the larger group showed a more pronounced increase in hematocrit and hemoglobin, a reduction in the total number of transfusions, and a shorter duration of hospitalization after transfusion in preterm infants without increasing complications.

Outcomes of Patient Care and Factors Associated with the Complications in Very Low Birth Weight Preterm Infants in the Neonatal Intensive Care Unit

This retrospective study determined the outcomes and associated factors with complications among very low birth weight preterm infants (VLBW) in the neonatal intensive care unit at Ramathibodi Chakri Naruebodindra Hospital. A total of 64 newborns with birth weight ≤ 1,500 grams and gestational age ≤ 32 weeks were included from January 1, 2019 to June 30, 2022. The statistics used for data analysis were percentage, mean, and standard deviation of mean. The Chi-square and Fisher's exact test were used for analysis of relationship between the complications. The results showed that a number of baby survivors were 70.31%. The complications were found 33 cases (51.56%). The most common complications were respiratory distress syndrome (92.19%), bronchopulmonary dysplasia (65.63%), and jaundice (81.25%). The related factors with the complications were birth weight and blood transfusions (p-value= 0.003 and 0.013, respectively). This research findings indicated that the VLBW group had a high mortality and complication rate.

Current diagnosis and treatment practice for pulmonary hypertension in bronchopulmonary dysplasia-A survey study in Germany (PUsH BPD).

Pulmonary hypertension (PH) is the most severe complication in preterm infants with bronchopulmonary dysplasia (BPD) and associated with significant mortality. Diagnostic and treatment strategies, however, still lack standardization. By the use of a survey study (PH in BPD), we assessed clinical practice (diagnosis, treatment, follow-up) in preterm infants with early postnatal persistent pulmonary hypertension of the newborn(PPHN) as well as at risk for or with established BPD-associated PH between 06/2018 and 10/2020 in two-thirds of all German perinatal centers with >70 very low birthweight infants/year including their cardiology departments and outpatient units. Data wereanalyzed descriptively by measures of locations and distributional shares. In routine postnatal care, clinical presentation and echocardiography were reported as the main diagnostic modalities to screen for PPHN in preterm infants, whereas biomarkers brain natriuretic peptide/N-terminal pro b-type natriuretic peptide were infrequently used. For PPHN treatment, inhaled nitric oxidewas used in varying frequency. The majority of participants agreed to prescribe diuretics and steroids (systemic/inhaled) for infants at risk for or with established BPD-associated PH and strongly agreed on recommending respiratory syncytial virus immunization and the use of home monitoring upon discharge. Reported oxygen saturation targets, however, varied in these patients in in- and outpatient care. The survey reveals shared practices in diagnostic and therapeutic strategies for preterms with PPHN and BPD-associated PH in Germany. Future studies are needed to agree on detailed echo parameters and biomarkers to diagnose and monitor disease next to a much-needed agreement on the use of pulmonary vasodilators, steroids, and diuretics as well as target oxygen saturation levels.
