Obesity is a public health challenge, especially in adolescence, a stage characterized by physiological and behavioral changes that may influence energy balance, lifestyle choices, and long-term health trajectories. Although self-image place a significant role on weight perception, there is no consensus on the impact of self-perceived weight on actual weight development. While some studies suggest that underestimating weight may contribute to subsequent weight gain, others suggest the contrary. The aim of this study was to analyze the influence of weight perception on the evolution of body composition in adolescents followed in an Adolescent Obesity Clinic. An exploratory, longitudinal, retrospective study was carried out, analyzing data from 131 adolescents with obesity (BMI Z-Score ≥ 2.0), with valid data from at least two obesity appointments. 44.3% of the participants had a correct perception of their weight evolution; 41.4% perceived an increase, with real weight loss and 7.1% reported having no perception at all of their weight evolution. Lack of perception of weight evolution was associated with an increase in hip circumference (β = 1.021; 95%CI: 0.791 to 1.318; R2 = 31.6%; p = .012). The correct perception of weight gain, compared to the wrong perception of weight loss, was associated with a greater increase in BMI (respectively, β = 5.833; 95%CI: 2.223; 15.304; R2 = 67.2%; p < .001; β = .131; 95%CI: 0.003; 0.292; R2 = 85%; p < .001).
Conclusion: Accurate perception of body weight changes may influence positively body composition in adolescents with obesity.
What is known: • Adolescence is a critical developmental period for obesity, during which body image and weight perception play a central role in health behaviors and treatment engagement. • Weight status misperception is common among adolescents with obesity and may act as a barrier to effective weight management; however, data focusing specifically on adolescents under obesity treatment are limited.
What is new: • In adolescents with obesity followed in a specialized clinic, inaccurate and lack of perception of weight change is highly prevalent, even under regular clinical monitoring, being associated with unfavorable changes in body composition. • Accurate perception of weight change emerges as a relevant factor linked to body composition evolution, underscoring the clinical importance of assessing and addressing weight perception during adolescent obesity treatment.

Lung ultrasound (LUS) and targeted neonatal echocardiography (TNE) are employed in some neonatal intensive care units throughout the hospital stay to monitor heart- and lung-related morbidities. However, preterm infants are at risk of increased rates of respiratory and cardiovascular morbidities across their lifespan. This commentary aims to define the utility of long-term TNE and LUS follow-up and to assess the challenges of incorporating these techniques into long-term practice. The cardiovascular phenotype of bronchopulmonary dysplasia (BPD) includes diverse cardiac and extracardiac anomalies. Many of these arise during hospitalization and can be detected on a multiparametric echocardiography examination. Nonetheless, several complications of prematurity related to pulmonary vascular disease arise after discharge, notably acute and chronic pulmonary hypertension and pulmonary vein stenosis. Similarly, LUS facilitates the diagnosis and prediction of several respiratory conditions affecting preterm infants during hospitalization, including respiratory distress syndrome and BPD. Limited data exist on LUS evolution after discharge. Multiple studies demonstrated that TNE significantly improves clinical and therapeutic outcomes in critically ill neonates, while evidence supporting LUS utility, though limited, continues to accumulate. Implementation of both LUS and TNE in preterm follow-up is challenged by limitations in training, resources, and institutional support.
Conclusion: Available evidence supports continuous ultrasound cardiopulmonary monitoring from birth through hospital discharge and into long-term follow-up. Neonatologists should look beyond immediate perinatal complications, as cardiorespiratory morbidities may remain subclinical yet emerge months to years later. Their unique integrated assessment of the cardiopulmonary system, coupled with safe and accessible tools, supports post-discharge TNE-LUS implementation without substantial barriers.
What is known: • LUS and TNE are typically utilized during the admission period, a role that is well-defined and extensively documented in the literature. • After discharge, echocardiography provides comprehensive longitudinal data, whereas LUS has been poorly investigated.
What is new: • The utilization of LUS and integrated TNE-LUS after discharge represents a significant research gap and a field of considerable potential utility in the long-term management of preterm infants. • Given their safety profile and accessibility, no substantial barriers preclude their post-discharge implementation.

Gastrointestinal endoscopy is rarely performed in neonates due to concerns regarding safety and technical feasibility. This study aimed to evaluate its safety, feasibility, and diagnostic yield, and to explore its role as both a diagnostic and therapeutic tool in neonatal gastrointestinal diseases. This retrospective study included 42 neonates, both preterm and term, who underwent gastrointestinal endoscopy at Shanghai Children's Hospital between 2015 and 2025. Indications for endoscopy, endoscopic findings, therapeutic approaches and follow-up outcomes were analyzed. All neonates underwent successful gastroscopy, including 4 who also received colonoscopy. The cohort included both term and preterm infants. The most common indication was gastrointestinal bleeding, particularly hematemesis. In preterm neonates, the primary indications were feeding intolerance and the need for enteral nutritional support. Abnormal endoscopic findings were identified in over 85.7% of infants, including mucosal erosion, ulcer, hemorrhagic lesion, congenital or acquired mechanical obstruction and inflammation. Endoscopic interventions included topical hemostatic therapy, nasojejunal tube placement, and balloon dilation. No procedure-related complications such as perforation, respiratory deterioration were observed.
Conclusions: With ongoing advances in gastrointestinal endoscopy and increasing clinical experience, its use in neonates has expanded. In some cases, endoscopy serves as an adjunct to diagnostic evaluation and therapeutic management.
What is known: • Gastrointestinal endoscopy is rarely performed in neonates due to technical limitations and concerns regarding safety. • Most existing studies involve small case series, offering limited data on diagnostic yield and therapeutic potential.
What is new: • A 10-year clinical cohort demonstrates that endoscopy is safe and feasible in both term and preterm neonates using ultrathin instruments. • Endoscopy provides substantial diagnostic value for diverse neonatal gastrointestinal conditions and enables targeted therapeutic interventions, including topical hemostatic therapy, Nasojejunal tube placement, and balloon dilation.

Lumbar puncture (LP) is a common but challenging procedure in neonates, with reported high rates of failure and traumatic taps. Real-time ultrasound (US) guidance may improve accuracy and safety, but evidence in the neonatal population remains limited. We retrospectively reviewed five neonates who underwent two-operator real-time US-guided LP in a tertiary neonatal intensive care unit between 2023 and 2024. Both static pre-procedural assessment and dynamic real-time guidance were applied. Demographic data, operator experience, procedural details, and outcomes were collected. The median gestational age at birth was 38 weeks (range 32-41). At the time of LP, postmenstrual age ranged from 33 to 44 weeks and weight from 1820 to 3960 g. Three procedures were performed by inexperienced operators, one by an intermediate, and one by an experienced operator. All LPs were successfully completed on the first attempt, irrespective of operator experience or patient position (lateral or seated). No traumatic LPs occurred, and no complications were observed. Cerebrospinal fluid (CSF) analysis yielded diagnostic results in all cases, including one case of parechovirus meningitis.Conclusion: Our case series demonstrates that real-time US guidance allows safe and effective LP in neonates, achieving 100% success without trauma even when performed by inexperienced operators. These findings support the feasibility of incorporating US-guided LP into routine neonatal practice. Larger prospective studies are warranted to confirm its benefits and define standardized protocols. What is Known: • Lumbar puncture (LP) in neonates has a high failure and traumatic tap rate compared to older children • Real-time ultrasound guidance can increase LP success and reduce complications in pediatric patients What is New: • Ultrasound guidance proved effective regardless of operator experience, suggesting a role in training and skill acquisition • These findings support the feasibility of systematically implementing ultrasound-guided LP in neonatal clinical practice.

<p><p>After the widespread use of pneumococcal conjugated vaccines (PCVs), pneumococcal carriage, especially due to some vaccine serotypes, has been shown to decrease, but carriage with non-vaccine serotypes and some persistent vaccine types of lineages has been demonstrated to continue. Evaluation of pneumococcal carriage helps to understand disease epidemiology. In this multicenter study, we aimed to determine pneumococcal carriage and serotype distribution in children, adolescents, and young adults aged 0-24 years in Türkiye after the pandemic era. This multicenter study was conducted between April and August 2022 in 1585 healthy children, adolescents, and young adults (aged between 0 and 24 years) in nine centers in Türkiye. Demographics, schooling/day‑care, smoking exposure, recent upper respiratory tract infection (URTI), antibiotic use (1 and 3 months), COVID‑19 infection/vaccination, and pneumococcal vaccination history were recorded. Nasopharyngeal swab samples were taken from all participants. Streptococcus pneumoniae was detected by real‑time polymerase chain reaction (PCR); positives were serotyped by singleplex real‑time PCR assays targeting 33 serotypes/serogroups. Among 1 585 participants (797 female; age distribution 0-5 years 22.0%, 6-10 years 29.3%, 11-15 years 16.8%, 16-18 years 12.9%, 19-24 years 19.0%), overall pneumococcal carriage prevalence was 19.6% (311/1 585). Age‑specific prevalences were 20.7% (0-5 years), 21.8% (6-10 years; peak), 19.1% (11-15 years), 15.6% (16-18 years), and 18.2% (19-24 years). Two‑thirds (66.2%) had received ≥ 1 PCV dose (coverage ≥ 82% through 15 years, declining to 43.9% at 16-18 years and 13.3% at 19-24 years). Vaccination was associated with significantly lower carriage only in children ≤ 10 years: 0-5 years 17.8% vs 43.6% (OR 0.28, 95% CI 0.13-0.60, p < 0.001); 6-10 years 19.7% vs 32.4% (OR 0.51, 0.28-0.93, p = 0.021). No significant differences were seen in older strata or overall (18.8% vs 21.3%, OR 0.85, 0.65-1.12). Of 311 isolates, 225 (72.4%) were typed (27 serotypes) and 86 (27.6%) were not defined. Dominant serotypes were 19F, 6A/B, 3, 23F, and 15B/C; PCV13 serotypes comprised 77.3% of typed isolates. Theoretical vaccine coverage among 225 typed isolates increased from 61-64% (PCV7/10) to 77.3% (PCV13), 78.2% (PCV15), 88.4-90.2% (PCV20/24), plateauing at 93.3-93.8% for PCV31/25. Theoretical vaccine coverage in children aged below 5 years of age was 66.7% for PCV13, 70.0% for PCV15, and 88.3% for PCV20. The frequency of PCV13 serotypes in children vaccinated with PCV13 was significantly lower than in unvaccinated children in children below 5 years of age.</p><p><strong>Conclusion: </strong>Post‑pandemic pneumococcal carriage in Türkiye remains 19.6% across childhood. Direct protection against nasopharyngeal carriage was evident in children ≤ 10 y. Higher‑valency PCVs and enhanced genomic serotype surveillance are needed to address residual carriage and guide future immunization strategi
在广泛使用肺炎球菌结合疫苗(PCVs)后,肺炎球菌携带,特别是由于某些疫苗血清型,已被证明减少,但非疫苗血清型和一些持续疫苗类型谱系的携带已被证明继续存在。肺炎球菌携带的评估有助于了解疾病流行病学。在这项多中心研究中,我们旨在确定大流行时期后 rkiye 0-24岁儿童、青少年和年轻人的肺炎球菌携带和血清型分布。这项多中心研究于2022年4月至8月在日本9个中心的1585名健康儿童、青少年和年轻人(年龄在0至24岁之间)中进行。记录了人口统计学、上学/日托、吸烟暴露、近期上呼吸道感染(URTI)、抗生素使用(1个月和3个月)、COVID - 19感染/疫苗接种和肺炎球菌疫苗接种史。从所有参与者身上采集鼻咽拭子样本。采用实时聚合酶链反应(PCR)检测肺炎链球菌;通过针对33个血清型/血清组的单路实时PCR检测对阳性进行血清分型。在1585名参与者中(797名女性,年龄分布0-5岁22.0%,6-10岁29.3%,11-15岁16.8%,16-18岁12.9%,19-24岁19.0%),肺炎球菌携带总患病率为19.6%(311/ 1585)。不同年龄的患病率分别为20.7%(0-5岁)、21.8%(6-10岁;高峰)、19.1%(11-15岁)、15.6%(16-18岁)和18.2%(19-24岁)。三分之二(66.2%)接种了≥1剂PCV(15岁覆盖率≥82%,16-18岁下降到43.9%,19-24岁下降到13.3%)。仅在≤10岁的儿童中接种疫苗与显著降低的携带率相关:0-5岁为17.8% vs 43.6% (OR 0.28, 95% CI 0.13-0.60, p)结论:大流行后的肺炎球菌携带率在整个儿童期仍为19.6%。在≤10岁的儿童中,对鼻咽载体的直接保护是显而易见的。需要更高的pcv价和加强基因组血清型监测,以解决残留载体问题并指导未来的免疫策略。已知情况:•肺炎球菌结合疫苗(PCVs)大大减少了侵袭性肺炎球菌疾病,但由于血清型替代,鼻咽部定植持续存在。•在2019冠状病毒病大流行之后,呼吸道病原体流行病学发生了重大变化,但关于肺炎球菌携带和血清型分布的当代大流行后数据仍然很少。新发现:•这是基耶病毒感染后肺炎球菌携带的首个多中心研究,涵盖了整个0-24岁年龄段,显示携带保持稳定在20%左右。•预防携带的直接疫苗保护仅限于≤10岁的儿童,对青少年或青壮年没有可衡量的影响。一些疫苗血清型和非疫苗血清型仍然占主导地位,高价pcv将显著提高理论覆盖率。

No significant differences were seen in older strata or overall (18.8% vs 21.3%, OR 0.85, 0.65-1.12). Of 311 isolates, 225 (72.4%) were typed (27 serotypes) and 86 (27.6%) were not defined. Dominant serotypes were 19F, 6A/B, 3, 23F, and 15B/C; PCV13 serotypes comprised 77.3% of typed isolates.

<p><p>Predicting extubation readiness in the neonatal intensive care unit (NICU) remains difficult. Prolonged mechanical ventilation may contribute to ventilator-induced diaphragmatic dysfunction, whereas premature extubation increases morbidity. We evaluated whether diaphragm ultrasound (DUS) parameters, alone or integrated with lung ultrasound aeration scoring, predict extubation outcomes in ventilated neonates. In this prospective, single-center pilot diagnostic accuracy study, 72 mechanically ventilated neonates underwent a standardized spontaneous breathing trial (SBT) on a Hamilton-C1 Neo ventilator while intubated. Index tests included diaphragmatic excursion (DE), inspiratory and expiratory diaphragm thickness (DTi, DTe), and inspiratory velocity, alongside lung aeration assessment using the LUS aeration score (LUS, 0-18; 6 regions) and the extended LUS aeration score (eLUS, 0-30; 10 regions). The reference standard was extubation outcome, with extubation failure defined as reintubation within 48 h. Discrimination was assessed using receiver operating characteristic (ROC) analyses (AUC with 95% confidence intervals), with DeLong tests for pairwise AUC comparisons. Extubation succeeded in 53/72 (73.6%) and failed in 19/72 (26.4%).

Pediatric battery ingestion can result in serious complications and mortality. We aimed to determine the incidence and complication rate of pediatric battery ingestion in the Netherlands. Cases of pediatric battery ingestion, including patient characteristics, battery characteristics, complications and interventions (2018-2021) were prospectively reported by pediatricians using the Dutch Pediatric Surveillance System and combined with population-related data of Statistics Netherlands. Follow-up data were assessed by standardized questionnaires. In total, 153 episodes of ≥ 1 battery ingestion were reported (49.7% female, median age 2.8 years). An average of 38 episodes per year, reflecting an incidence of 1.18 episodes per 100,000 children per year was found. Most ingested batteries (87.6%) were button batteries. Complications occurred in 26 (17.0%) of battery ingestions. Severe complications were mortality following esophageal-aortal fistula causing hemorrhagic shock (n = 1; 0.7%), carotid artery bleeding (n = 1; 0.7%), tracheal-esophageal fistula (n = 1; 0.7%) and (pneumo)mediastinitis (n = 2; 1.3%). In most cases, batteries were ingested as loose items (n = 47; 30.7%), or as components of lights (n = 25; 16.3%) and toys (n = 22; 14.4%). Complications were significantly associated with younger age (p 0.004), symptoms at first presentation (p < 0.001), larger batteries (p 0.021), and location in the upper (p < 0.001) and middle third part (p 0.037) of the esophagus.
Conclusion: The population-related incidence of pediatric battery ingestion is 1.18 episodes per 100,000 children per year in the Netherlands with 17% complications. Battery swallowing in young children is a life-threatening emergency-urgent action and increased awareness among politicians, industry and healthcare professionals are essential to prevent serious harm.
What is known: • Battery ingestion can lead to severe complications and mortality. • Young children are prone to accidental button battery ingestion due to oral exploration. • Esophageal impaction and related complications are more common in children compared to adults due to small anatomy.
What is new: • The incidence rate of pediatric battery ingestion is rarely described worldwide. In the Netherlands, the incidence is 1.18 per 100,000 children per year. • Unfortunately, complications are relatively often after ingestion (17%).

This prospective observational study investigated the hemodynamic changes in cardiac function and cerebral blood flow velocity (CBFV) in neonates with hypoxic-ischemic encephalopathy (HIE) requiring therapeutic hypothermia (TH). Data were collected at five timepoints, viz., pre-TH (T0), 0-24 h of TH (T1), 24-48 h of TH (T2), 48-72 h of TH (T3), and within 24 h postrewarming (T4). Healthy neonates served as the control group (n = 20). A total of 43 neonates with HIE requiring TH were enrolled. Left ventricular output was significantly lower than that in the control group at T1 and T2 and increased from T1 to T4 (92.8 ± 29.5 ml/kg/min vs. 103 ± 29.7 ml/kg/min vs. 109.5 ± 28 ml/kg/min vs. 144.5 ± 34.4 ml/kg/min (T4 vs. T1, T2, or T3: p < 0.05). Systolic mitral annular velocity and systolic tricuspid annular velocity were lower than those in the control group across T1-T4 (p < 0.05). Middle cerebral artery peak systolic flow velocities increased across T1-T3 (T1 vs. T2, p < 0.05; T1 vs. T3, p < 0.05; T1 vs. T4, p < 0.05).
Conclusion: Irrespective of HIE severity, left cardiac output reduced but consistently increased over time in neonates with HIE who required TH. The trend of CBFV gradually increased throughout the TH and rewarming phase.
What is known: • TH is the standard neuroprotective treatment for moderate-to-severe neonatal HIE, yet survivors continue to face significant neurological sequelae. • Hypoxic-ischemic injury often leads to myocardial dysfunction, and TH itself induces hemodynamic alterations; however, the dynamic evolution of cardiac function and cerebral hemodynamics in neonates with HIE during TH has not been fully elucidated.
What is new: • This study demonstrates that, regardless of HIE severity, left cardiac output decreases initially during TH but consistently recovers over time, and biventricular longitudinal systolic function does not deteriorate during the hypothermia phase. • We further observed a gradual increase in CBFV throughout both TH and rewarming.

本前瞻性观察性研究探讨了需要低温治疗的新生儿缺氧缺血性脑病(HIE)心功能和脑血流速度(CBFV)的血流动力学变化。数据采集于5个时间点,分别为TH前(T0)、TH后0-24 h (T1)、TH后24-48 h (T2)、TH后48-72 h (T3)和预热后24 h内(T4)。健康新生儿作为对照组(n = 20)。共纳入43例需要TH的HIE新生儿。左心室输出量在T1和T2时明显低于对照组,从T1到T4增加(92.8±29.5 ml/kg/min vs. 103±29.7 ml/kg/min vs. 109.5±28 ml/kg/min vs. 144.5±34.4 ml/kg/min) (T4 vs. T1, T2或T3: p结论:无论HIE严重程度如何,需要TH的HIE新生儿左心输出量减少但随时间持续增加。在TH期和复温期,CBFV呈逐渐增加的趋势。•TH是中重度新生儿HIE的标准神经保护治疗,但幸存者仍面临严重的神经系统后遗症。•缺氧缺血性损伤常导致心肌功能障碍,TH本身可引起血流动力学改变;然而,新生儿HIE在TH期间心功能和脑血流动力学的动态演变尚未完全阐明。新发现:•本研究表明,无论HIE的严重程度如何,左心输出量在TH期间最初会减少,但随着时间的推移会逐渐恢复,双心室纵向收缩功能在低温期不会恶化。•我们进一步观察到CBFV在TH和复温过程中逐渐增加。此外,即使使用谷歌Chrome,它是不可能在编辑过程中创建换行,而添加这一节。我真诚地为这可能造成的任何格式问题道歉。

Differentiating serious bacterial infections (SBIs) from viral illnesses in infants remains challenging. Although serum procalcitonin (PCT) is a well-established biomarker, its measurement requires invasive blood sampling. This study investigated the correlation between salivary and serum PCT and evaluated the diagnostic accuracy of salivary PCT for identifying SBIs in infants under 1 year of age. This prospective observational study included 160 infants under one 1 year of age presenting to a pediatric emergency department with suspected SBI. Paired serum and saliva samples were collected. Salivary PCT and serum PCT levels were measured. Serum C-reactive protein (CRP), a routinely used inflammatory marker in pediatric emergency practice, was included as a comparator biomarker. Patients were classified into SBI and viral infection groups based on final diagnoses. The diagnostic accuracy of the biomarkers was assessed and compared using receiver operating characteristic (ROC) curve analysis.Of the 160 infants (median age 8 months; 63% male), 11.3% (n = 18) were diagnosed with SBI and 88.7% (n = 142) with viral infections. Median salivary PCT levels were markedly higher in the SBI group than in the viral infection group (69.3 pg/mL vs. <0.01 pg/mL; p < 0.001). The area under the curve (AUC) for diagnosing SBI was 0.92 for salivary PCT, 0.96 for serum PCT, and 0.88 for serum CRP. At a cutoff value of 31.3 pg/mL, salivary PCT demonstrated a sensitivity of 89% and a specificity of 92.3%, with a negative predictive value (NPV) of 98.7%. A weak but statistically significant correlation was found between serum and salivary PCT levels (r = 0.250; p = 0.001). Conclusion: Salivary PCT shows strong correlation with serum PCT and demonstrates high diagnostic accuracy as a non-invasive biomarker for identifying SBIs in infants. Its performance approaches that of serum PCT and exceeds that of serum CRP, highlighting its potential clinical value in reducing the need for invasive blood sampling. What is Known: • Serum procalcitonin (PCT) is a well-established marker for detecting serious bacterial infections (SBI) in infants, surpassing CRP, though it requires invasive sampling. What is New: • Salivary PCT demonstrates comparable diagnostic performance to serum PCT and exceeds CRP, highlighting its potential as a non-invasive alternative for SBI assessment in infants.

To evaluate the diagnostic performance of and the potential reduction in blood sampling by (a) visual assessment (VA) for jaundice and (b) transcutaneous bilirubinometry (TcB) at 12-24 h after stopping phototherapy in detecting rebound hyperbilirubinemia requiring re-initiation of phototherapy in neonates born at ≥ 35 weeks' gestation. This prospective observational study was conducted at a tertiary neonatal unit in India. Eligible neonates underwent VA using Modified Kramer's method by a neonatal fellow with > 3 years of pediatrics training, TcB using Dräger JM-105™, and total serum bilirubin (TSB) by point-of-care spectrophotometry (One Beam; Ginevri, Italy) at either 12 h (neonates with hemolytic jaundice) or 24 h (neonates with non-hemolytic jaundice) after phototherapy cessation. Outcomes included sensitivity, specificity, likelihood ratios, and reduction in TSB sampling. Among 160 enrolled neonates (gestation: 36 ± 3 weeks; birthweight: 2743 ± 483 g; 35 [21.9%] with hemolytic jaundice), rebound hyperbilirubinemia occurred in 8 (5%). Sensitivity was 100% for both VA and TcB, with VA demonstrating higher specificity (88.2% vs. 71.7%). Positive predictive values were low (VA: 30.8%; TcB: 15.7%), while negative predictive values were 100% for both. Positive likelihood ratios for VA and TcB were 8.4 and 3.5, respectively. VA and TcB could have reduced TSB sampling in 134 (83.8%; 95%CI 77.0-88.7) and 109 (68.1%; 95%CI 60.4-70.9) neonates, respectively.
Conclusions: Given their excellent sensitivity and negative predictive values, VA and TcB can enable ruling out rebound hyperbilirubinemia after stopping phototherapy. Using them as primary screening tools can significantly reduce the need for blood sampling to detect rebound hyperbilirubinemia.
What is known: • Rebound hyperbilirubinemia requiring re-initiation of phototherapy occurs in a subset of neonates with pathological hyperbilirubinemia. • While visual assessment (VA) and transcutaneous bilirubinometry (TcB) are non-invasive methods for monitoring jaundice, their role in identifying rebound hyperbilirubinemia remains unclear.
What is new: • This study shows excellent sensitivity and negative predictive values of VA and TcB for detecting rebound hyperbilirubinemia. • The results suggest the potential of these two non-invasive methods to decrease blood sampling for serum bilirubin levels, making them valuable tools particularly in resource-constrained settings.
