Slit lamp examination and Scheimpflug imaging of 8205 participants, aged 35 to 74, were assessed and signs of cataract or pseudophakia analyzed. The research aimed to explore the correlation between fetal growth restriction and/or prematurity indicated by BW and the frequency of cataract and pseudophakia. In the univariable analysis, cataract was initially associated with low and high BW, but this association disappeared after adjusting for age, sex, examiner and cardiovascular risk factors. No association was found between low BW and pseudophakia or the frequency of cataract surgery within 5 years. The study reveals novel insights from a large population-based study specifically exploring this association.Keywords: Cataract, pseudophakia, birth weight, epidemiology, population-based study

The study involved analyzing fundus photographs of 6855 participants, aged 35 to 74, to assess signs of HR, classified according to the Mitchell-Wong Classification. The research aimed to explore the correlation between fetal growth restriction indicated by BW and the frequency of HR. The results showed that the frequency of HR did not significantly differ among groups with different BW ranges. In the univariable analysis, HR was initially associated with high BW, but this association disappeared after adjusting for age, sex, and cardiovascular risk factors. No association was found between low BW and HR. The study reveals novel insights as there are no prior population-based studies specifically exploring this association.Keywords: birth weight, hypertensive retinopathy, epidemiology, population-based study

This study investigated the effects of being born small for gestational age (SGA) on peripapillary retinal nerve fiber layer (pRNFL) thickness in adults born at term.Methods: A retrospective cohort study was conducted with a prospective ophthalmologic examination of participants born at full-term (gestational age ≥ 37 weeks) between 1969 and 2002. All participants were examined with spectral-domain optical coherence tomography and grouped according to their birth weight in correlation to gestational age as former moderate (birth weight (BW) percentile 3rd to < 10th) and severe SGA (< 3rd percentile), normal (10th-90th percentile, AGA), and moderately (> 90th to 97th percentile) and severely (> 97th percentile) large for gestational age (LGA) adults (18 to 52 years).Results: Overall, 547 eyes of 285 individuals (age 29.9± 9.4 years, 151 females) born at term were included. Multivariable regression analyses revealed a strong association between a lower global pRNFL thickness in the severe SGA (B=− 8.99 [95%-CI: − 12.68; − 5.30] μm; p< 0.001) and in the moderate SGA groups (B=− 6.40 [95%-CI: − 10.29; − 2.50] μm; p=0.001) compared to the reference AGA group.Conclusion: Our results indicate that restricted fetal growth affects neurologic tissue development of the optic nerve head, particularly in individuals born severely SGA at term. This indicates that fetal growth restriction may exert disturbances in the development of neurologic tissue, which persists in adulthood.Keywords: birth weight, small for gestational age, large for gestational age, peripapillary retinal nerve fiber layer, optic nerve head, epidemiology

In preterm infants receiving supplemental oxygen, manual control of the inspired oxygen fraction is often time-consuming and inappropriate. We developed a system for automatic oxygen control and hypothesized that this system is more effective than routine manual oxygen control in maintaining target arterial oxygen saturation levels. We performed a randomized controlled crossover clinical trial in 12 preterm infants receiving nasal continuous positive airway pressure and supplemental oxygen. Periods with automatic and routine manual oxygen control were compared with periods of optimal control by a fully dedicated person. The median (range) percentage of time with arterial oxygen saturation levels within target range (87-96%) was 81.7% (39.0-99.8) for routine manual oxygen control, 91.0% (41.4-99.3) for optimal control, and 90.5% (59.0-99.4) for automatic control (ANOVA: p = 0.01). Pairwise post hoc comparisons revealed a statistically significant difference between automatic and routine manual oxygen control (Dunnett's test: p = 0.02). The frequency of manual oxygen adjustments was lowest in automatic control (Friedman's test: p < 0.001). Automatic oxygen control may optimize oxygen administration to preterm infants receiving nasal continuous positive airway pressure and reduce nursing time spent with oxygen control.

OBJECTIVES: Sleep-disordered breathing is associated with impaired behavior and poor academic performance in children. We aimed to determine the extent of behavioral problems in snoring children, clarify the role of intermittent hypoxia, and test the reversibility of impaired behavior and poor academic performance. METHODS: In 1144 children, habitual snoring (HS; snoring frequently or always) and impaired behavior were assessed using parental questionnaires. Intermittent hypoxia (ie, presence of > or =5 arterial oxygen desaturations by > or =4% or > or =1 desaturation to < or =90%) was investigated with pulse oximetry. Poor academic performance (grade 4-6 on a 6-point scale in mathematics, science, or spelling) was based on the last school report. HS, impaired behavior, and academic performance were reevaluated after 1 year. Adjusted odds ratios (ORs) were calculated using unconditional logistic regression. RESULTS: HS was significantly associated with hyperactive (OR: 2.4) and inattentive behavior (OR: 4.0), daytime tiredness (OR: 7.1), and sleepiness (OR: 2.6-4.8). These associations were independent of intermittent hypoxia. HS was also significantly associated with bad conduct (OR: 2.8), emotional symptoms (OR: 5.5), and peer problems (OR: 9.7). At follow-up, hyperactive and inattentive behavior but not academic success had significantly improved in children in whom HS had ceased. CONCLUSIONS: We suggest that impaired behavior is a key feature of HS independent of intermittent hypoxia and improves when HS ceases. [ABSTRACT FROM AUTHOR]

Objective To determine reference values for pulse oximeter saturation (SpO(2)) variables and desaturation event indices in healthy term neonates during their first 5 days of life, and to compare two definitions for the identification of desaturation events. Design Observational study (case series). Setting Maternity ward, Department of Neonatology, University Children's Hospital, Tuebingen, Germany. Patients 209 healthy term neonates (50% boys), median (minimum-maximum) age 2 (0-5) days. Main outcome measures SpO(2) variables (eg, median SpO(2)) and desaturation events obtained by motion-resistant pulse oximetry (VitaGuard 310; Getemed, incorporating Masimo SET). Desaturation events were identified based either on a good signal quality (SIQ) provided by the device or on the combination of a good SIQ and an undisturbed pulse waveform (SIQ+PW). Desaturation event indices were calculated as desaturation events divided by hour of artefact-free recording time. Results The mean (SD) of the obtained median SpO(2) was 97.3% (1.4%). There were 36 (17%) subjects with desaturation events to <80% SpO(2) based on SIQ, and 26 (12%) based on SIQ+PW. Median desaturation event rate to <80% SpO(2)/h (75th centile; 95th centile; maximum) was 0 (0; 0.6; 2.3) based on SIQ, and 0 (0; 0.4; 1.7) based on SIQ+PW. Conclusions Desaturation events to <80% SpO(2) were rare in our sample of healthy term neonates during their first 5 days of life. Analysis of SIQ alone could be a quick and simple alternative to traditional analysis of PW. The presented reference values may be used for clinical decision making. [ABSTRACT FROM AUTHOR]

Background: Apnoea of prematurity has been shown to respond to changes in posture. Objective: To investigate the effect of three postural interventions on the rate of bradycardia and desaturation events. Methods: 18 infants (< or =32 weeks' gestational age; 11 boys) with apnoea of prematurity underwent recordings of breathing movements, electrocardiogram and instantaneous heart rate, pulse oximeter saturation (SpO2), photoplethysmographic waveforms and digital video frame while in one of three different prone positions. The following interventions were applied in random order: horizontal position (HP), 15 degrees head-up tilt position (TP) and three-level position (3P) according to Kinaesthetics Infant Handling. The primary study variable was the combined event rate of desaturations (SpO2 <85%) and bradycardias (heart rate <80 bpm). One secondary study variable was the duration of body movements. Results: The median (range) combined event rate was 26.7/h (0.3-72.7) in HP, 25.2/h (0.3-70.5) in TP and 21.2/h (0-66.3) in 3P (p>0.05). The median (range) duration of body movements was 10.8 s/h (0-48.2) in HP, 7.1 s/h (0-72.4) in TP and 7.0 s/h (0-47.7) in 3P (p>0.05). Conclusions: No significant advantage of a head-up tilt or a three-level position over a standard horizontal position could be confirmed. [ABSTRACT FROM AUTHOR]

Objective: Children with special healthcare needs (SHCN) due to a chronic health condition perform more poorly at school compared with their classmates. We aimed to estimate the effects of past, current, transient, emerging and persistent SHCN on school performance in primary school children., Methods: Data from the German population-based prospective cohort study ikidS were used. The children withSHCN screener was administered before school entry (T1) and at the end of first (T2) and third grade (T3). Grades for German, maths and science (range: 1 (Very Good) to 6 (Failure)) were obtained at the end of third grade (age 8-9 years), and an average grade was calculated. Associations between the timing of SHCN and average grade were estimated by mixed linear regression models adjusted for potential confounding variables., Results: 751 children were included, and 21% had ever SHCN. Children with ever SHCN had poorer school performance than children with never SHCN (adjusted mean difference in average grade [95% CI]: 0.17 [0.06; 0.28]). SHCN in the third year were associated with a poorer average grade (0.29 [0.16; 0.41]) compared with healthy children. Only emerging (0.31 [0.15; 0.48]) and persistent (0.25 [0.07; 0.43]) SHCN were associated with average grade., Conclusions: This study demonstrates the negative effect of current, emerging and persistent SHCN on academic performance in primary school children. Consequently, students should be regularly assessed for SHCN during school age. Timely interventions may help reduce the adverse effects of chronic health conditions on academic achievements in childhood., Competing Interests: Competing interests: No, there are no competing interests., (© Author(s) (or their employer(s)) 2024.

Although the effect of early childhood stress on central nervous pain processing is well known, studies on the association of prematurity and chronic pain are scarce. This study used data from a single-centre retrospective cohort study followed by a prospective clinical examination and pain assessment. The study was based on data from the local birth registry. Newborns born between 1969 and 2002 who had reached adulthood were eligible .. Using a selection algorithm, a study cohort stratified by gestational age (GA) was recruited. Chronic pain conditions were assessed using questionnaire and standardized pain drawings. Data on the pre-, peri- and postnatal clinical course was assessed from medical records. Multivariable logistic regression analyses were conducted to investigate associations between prematurity and chronic pain with adjustment for age, gender, socioeconomic status, and perinatal stress factors. 427 participants born preterm and full-term were included (age 28.5 ± 8.7 years). Chronic pain conditions were similarly common between groups with different levels of prematurity (GA ≥ 37 weeks: 34.5 %, GA33-36 weeks: 37.6 %, GA32-29 weeks: 25.2 %, GA < 29 weeks: 30.4 %, p = 0.20). In multivariable analyses, no association between low GA and the presence of chronic pain was found (OR = 0.99 (CI95 %: 0.94-1.04, p = 0.63); this was also true for a subanalysis of widespread pain. While neither fetal nutritional status nor perinatal stressors were associated with pain, exposure to maternal but not paternal smoking during pregnancy was associated with increased risk to develop pain (OR = 2.77 (CI95 %: 1.31-5.88, p = 0.008) in adults born preterm and full-term. This study suggests that prematurity by itself does not increase the risk of chronic pain later in life, but provides preliminary evidence for maternal smoking during pregnancy as risk factor., Competing Interests: Declaration of competing interest The Gutenberg Prematurity Study was supported by the Ernst und Berta-Grimmke Stiftung, Stufe 1 support of the UM and the Else Kröner-Fresenius-Stiftung.

Background: Children with chronic illness perform poorer at school, and school well-being (SWB) may mediate this association. We investigated the association between chronic illness and three domains of SWB in children in first grade., Methods: Data from a German population-based prospective cohort study were used. Children with chronic illness were identified via their preschool health examination and follow-up parent surveys during first grade. Children were grouped as either (i) having current special health care needs (SHCN), (ii) having at least one physician diagnosis of a chronic illness but no current SHCN, or (iii) being healthy. SWB was assessed at the end of first grade and measured by the Questionnaire for the Assessment of Emotional and Social School Experiences of First and Second Grade Primary School Children. Based on SWB theory and previous frameworks, the following subscales were used: School-Related Self-Concept, Social Integration, and Joy of Learning. The sum score for each subscale was converted into area-transformed T-values (mean 50 and standard deviation 10). Associations between chronic illness groups and SWB subscales were investigated by multivariable linear regression models. Effect estimates were adjusted for potential confounding variables and standardized mean differences (SMD) were calculated., Results: Of the 1,490 children included, 15% had current SHCN and 37% had a physician diagnosis of a chronic illness but no current SHCN. Compared to healthy children, children with SHCN had lower scores for the School-Related Self-Concept and the Joy of Learning subscale (SMD -0.18 for both) but not for the Social Integration subscale. In contrast, children with a chronic condition but no SHCN had lower scores only for the Social Integration subscale (SMD -0.12)., Conclusions: Primary school students with a chronic illness with or without SHCN have lower SWB in some domains compared to their healthy peers. SWB may be a mediator in the association between chronic illness and poor school performance., Competing Interests: The authors declare that they have no competing interests., (© 2024 Schnick-Vollmer et al.)

Background: Extremely low gestational age neonates (ELGANs, i.e. those born before 28 weeks postmenstrual age (PMA)) often require supplemental oxygen and frequently experience intermittent hypo- and hyperoxemic episodes. Exposure to episodes with inadequate oxygen concentrations has been shown to be associated with an increased risk of retinopathy of prematurity (ROP), bronchopulmonary dysplasia (BPD), necrotizing enterocolitis (NEC), neurodevelopmental impairment (NDI) and death. Closed-loop automatic control of the inspiratory fraction of oxygen (FiO 2 -C) reduces number and duration of hypo- and hyperoxemic episodes in ELGANs. Its impacts on clinically important short- and long-term outcomes such as ROP, BPD, NEC, NDI and mortality have not yet been studied., Methods: An outcome-assessor-blinded, multicentre, randomized-controlled, parallel-group trial for superiority was designed to study the effects of FiO 2 -C (provided by standard infant ventilators) in addition to routine manual control (RMC) during respiratory support, compared to RMC only, on short- and long-term clinical outcomes in ELGANs. Two co-primary composite outcomes were defined: (i) death, severe ROP, BPD or NEC, assessed at 36 weeks PMA or, in case of ROP, until complete vascularization of the retina; (ii) death or NDI (defined as language/cognitive delay, motor impairment, severe visual impairment or hearing impairment), assessed at 2 years corrected age., Results: Primary outcomes will be compared between the two intervention groups using a Cochran-Mantel-Haenszel test. The factors considered for randomization (centre, sex and gestational age at birth (< 26 weeks and ≥ 26 weeks)) will be used to define strata. Results will be presented as adjusted odds ratios with two-sided 95% and 97.5% confidence intervals and two-sided p values., Conclusions: The statistical analyses for the FiO 2 -C trial were defined in the study protocol and specified in detail in this statistical analysis plan published prior to any statistical analysis.

Aim: The purpose of this study was to assess the prevalence of strabismus and nystagmus and to analyse associated factors in preterm and full-term infants in adulthood., Methods: The Gutenberg Prematurity Eye Study is a retrospective cohort study with a prospective ophthalmological examination of participants born preterm and full-term (aged 18-52 years). Perinatal data were carefully assessed for risk factors and comprehensive ophthalmological examinations were conducted. The association between strabismus and nystagmus was assessed by analysing 16 different perinatal and actual risk factors in multivariable analysis. Participants were grouped into full-term controls (gestational age (GA) at birth ≥37 weeks), preterm participants without retinopathy of prematurity (ROP) and GA 33-36 weeks (group 2), GA 29-32 weeks (group 3), GA ≤28 weeks (group 4), non-treated ROP (group 5) and treated ROP (group 6)., Results: In total, 892 eyes of 450 preterm and full-term individuals (mean age: 28.6 years, SD: ± 8.6 years, 251 females) were included. Strabismus was observed in 2.1% (3/140), 6.6% (9/137), 17.4% (16/92), 11.1% (2/18), 27.1% (13/48) and 60% (9/15) of participants and nystagmus in 0.7% (1/140), 1.5% (2/137), 4.3% (4/92), 5.6% (1/18), 10.4% (5/48) and 26.7% (4/15) of participants in the respective groups. In the multivariable regression model, strabismus was associated with GA (OR=0.90; p=0.046), anisometropia ≥1.5 diopter (OR=3.87; p=0.003), hypermetropia ≥2 diopter (OR=9.89; p<0.001) and astigmatism ≥1.5 diopter (OR=2.73; p=0.017). Esotropia was more frequent than exotropia and hypermetropia/hypometropia. Most strabismus cases occurred within the first 10 years of life. The strongest predictor associated with nystagmus was perinatal adverse events (OR=15.8; p=0.002)., Conclusion: Low GA and refraction of the eye are independent risk factors for strabismus, which typically occurs in the first 10 years of life. Perinatal adverse events are the most important factors for the presence of nystagmus in adulthood., Competing Interests: Competing interests: NP receives financial support and grants from Novartis, Ivantis, Santen, Thea, Boehringer Ingelheim Deutschland GmbH & Co.

Aims: The objective of this study was to assess overall and segmented trends in the incidence of type 1 diabetes mellitus (T1DM) and type 2 diabetes mellitus (T2DM) in children and adolescents younger than 20 years, from 2002 to 2022., Methods: This study used registry data on physician-diagnosed T1DM or T2DM from primary and secondary sources, covering the German federal state of North Rhine-Westphalia with 18 million inhabitants. The ages at T1DM and T2DM onset ranged from 0 to 19 and 10-19 years, respectively. The main outcomes were direct age- and/or sex-standardized incidence rates per 100,000 person-years (PYs) and trends estimated as annual percentage changes (APCs), both with 95 % confidence intervals. The segmented trends for subperiods were based on joinpoint regression models., Results: From 2002-2022, 17,470 and 819 persons had incident T1DM and T2DM, respectively. The total number of PYs was 73,743,982 for T1DM and 39,210,453 for T2DM, with a mean coverage rate of 98 % for T1DM and 90 % for T2DM. The standardized T1DM incidence increased from 17.6 [16.3;18.9} in 2002 to 33.2 [31.3;35.1] in 2022, with an APC of 2.7 % [2.3 %;3.1 %]. The standardized T2DM incidence increased from 1.3 [0.8;1.7] in 2002 to 2.8 [2.0;3.6] in 2022, with an APC of 6.4 % [4.9 %;8.0 %]. There were four different segmented trends for T1DM and T2DM, with the incidence peaking in 2021 and subsequently declining., Conclusions: The incidence rates of T1DM and T2DM have increased over the past 20 years, with a wave-like pattern during the Covid-19 pandemic., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Author(s).

Purpose: To examine potential changes in the foveal avascular zone (FAZ) during adulthood due to prematurity and retinopathy of prematurity (ROP), as assessed by measurements of the FAZ area and circularity., Methods: The Gutenberg Prematurity Eye Study is a retrospective German cohort study with a prospective ophthalmologic examination of adults aged 18 years to 52 years, born either preterm or full-term, using spectral-domain optical coherence tomography angiography. Participants were categorized into groups based on gestational age and postnatal ROP status. The study conducted multivariable linear regression analyses to explore associations with the FAZ., Results: The study cohort comprised 380 right eyes from individuals born both preterm and full-term, with an average age of 28.4 years ± 8.6 years, including 214 women. The FAZ area decreased as gestational age decreased: FAZ was 0.28 mm 2 ± 0.12 mm 2 in the control group, 0.21 ± 0.10 mm 2 at GA 33 weeks to 36 weeks, 0.18 mm 2 ± 0.10 mm 2 at GA 29 weeks to 32 weeks, 0.11 mm 2 ± 0.10 mm 2 at GA ≤28 weeks, 0.11 mm 2 ± 0.10 mm 2 in ROP without treatment, and 0.11 mm 2 ± 0.10 mm 2 in those requiring ROP treatment. In the multivariable analyses, smaller FAZ was independently associated with gestational age ( P < 0.05), increased foveal retinal thickness ( P < 0.05), and foveal hypoplasia ( P < 0.05). Moreover, no association was seen between visual acuity and FAZ., Conclusion: The main perinatal factor associated with a smaller FAZ in this German cohort is preterm birth, while ROP, ROP treatment, or other perinatal factors do not affect FAZ observed in adulthood. A smaller FAZ shape in preterm individuals might be an indicator of foveal hypoplasia.

Background: Vitamin B12 deficiency (VitB12D) might cause neuro-developmental impairment in the first year of life. Newborn screening (NBS) for VitB12D was shown to be technically feasible and early treated infants developed favorably. This study aims to evaluate the impact of NBS in prevention of symptomatic infantile VitB12D., Methods: In a nationwide surveillance study in cooperation with the German Pediatric Surveillance Unit, incident cases with VitB12D (<12 months of age) were prospectively collected from 2021 to 2022., Results: In total, 61 cases of VitB12D reported to German Pediatric Surveillance Unit were analyzed, either identified by NBS (N = 31) or diagnosed after the onset of suggestive symptoms (non-NBS; N = 30). Ninety percent of the infants identified by NBS were still asymptomatic, whereas the non-NBS cohort presented at median 4 month of age with muscular hypotonia (68%), anemia (58%), developmental delay (44%), microcephalia (30%), and seizures (12%). Noteworthy, symptomatically diagnosed VitB12D in the first year of life was reported 4 times more frequently in infants who did not receive NBS for neonatal VitB12D (14 in 584 800) compared with those screened for VitB12D as newborns (4 in 688 200; Fisher's Exact Test, odds ratio 4.12 [95% confidence interval: 1.29-17.18], P = .008). The estimated overall cumulative incidence was 1:9600 newborns per year for neonatal VitB12D and 1:17 500 for symptomatic infantile VitB12D., Conclusions: NBS for neonatal VitB12D may lead to a fourfold risk reduction of developing symptomatic VitB12D in the first year of life compared with infants without NBS., (Copyright © 2024 by the American Academy of Pediatrics.)

Objective: To assess the extent of perceived shared decision making (SDM) with parents of pediatric patients and to examine its association with characteristics of patients, professionals, and healthcare facilities., Methods: Parents of pediatric patients (n = 4383) were recruited in 15 social pediatric centers in Germany and provided information on perceived SDM (binary CollaboRATE pediatric score: optimal versus suboptimal extent of SDM), child age and sex, type of impairment, appointment, and healthcare professional present at the appointment. Organizational characteristics were assessed in a cross-sectional survey of staff at the study sites., Results: Overall, 58.4% of parents reported an optimal extent of SDM. The optimal extent of SDM was more likely reported by parents of girls (OR=1.27, p < 0.001) and children with physical (as opposed to cognitive and combined) impairments (OR=1.30, p = 0.006), and after appointments attended by allied health professionals (OR=1.28, p = 0.004). In addition, parents in facilities receiving financing in addition to compensation by statutory health insurance funds were less likely to report an optimal extent of perceived SDM., Conclusion: While SDM with parents was mostly related to individual characteristics of children and professionals at appointments, organizational characteristics seemed less relevant in our study., Practice Implications: Staff should be made aware of lower SDM with parents of boys, older children, and those with cognitive impairments, and trained to improve the SDM in these groups., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Authors.

Purpose: To explore differences in the relationship between gestational age (GA) and birth weight (BW) percentile and ocular geometry between males and females., Methods: The Gutenberg Prematurity Eye Study involved a prospective ophthalmic examination of adults, aged 18 to 52 years, who were born preterm or at term, in Germany. The associations between GA and BW percentile on the main outcome measures were evaluated by uni- and multivariable linear regression analyses. The main outcome measures were central corneal thickness, corneal radius, anterior chamber depth, lens thickness, posterior segment length, and central foveal thickness. Potential sex-specific differences and an effect modification by sex were analyzed., Results: This study involved 438 participants (245 females, 193 males) with an average age of 28.6 ± 8.7 years. In female participants, central foveal thickness was negatively associated with a higher GA (B = -2.99; P < 0.001). Similarly, male participants also demonstrated a negative association between central foveal thickness and GA (B = -4.27; P < 0.001). The multivariable model with effect modification revealed that the central foveal thickness was thicker with lower GA. There was an association between the effect modification of GA with sex and central foveal thickness, demonstrating a more pronounced effect of GA on central foveal thickness in male participants (B = 1.29; P = 0.04)., Conclusions: This study identified a sex-specific correlation between lower GA and thicker central foveal thickness, suggesting differences in the developmental trajectory of this biometric parameter concerning GA. A thicker central foveal thickness might affect the visual acuity of individuals born preterm in adulthood, with a more pronounced impact in males and a potential predisposition to age-related diseases later in life. Sex did not influence the association of GA or BW percentile to other ocular geometric parameters.

Aim: Children with special health care needs (SHCN) perform more poorly at school compared to their classmates. Specific causal pathways have not yet been extensively studied. Therefore, we investigated teacher-rated global attention, an important prerequisite for educational attainment, in children with SHCN., Methods: Data of a population-based prospective cohort study, which recruited preschool children from the Mainz-Bingen area, Germany, were analysed. Children with SHCN were identified by the Children with Special Health Care Needs screening tool. In 2016, global attention was reported by teachers at the end of first grade (mean age: 7.3 years) on a 5-point rating scale ranging from -2 through +2. Associations between SHCN consequences and teacher-rated attention were estimated by linear mixed models, adjusted for confounding variables., Results: We included 1921 children (51% males); of these, 14% had SHCN. Compared to their classmates, children with SHCN had poorer teacher-rated attention scores (adjusted mean difference: -0.35, 95% CI: -0.52 to -0.17). The effect was strongest among children with treatment or counselling for mental health problems or functional limitations. The effect remained after excluding children with attention deficit hyperactivity disorder from the analysis., Conclusion: Children with SHCN showed more teacher-rated attention problems, which could explain their lower educational attainment., (© 2024 The Authors.

Purpose: This study investigated the effects of prematurity and retinopathy of prematurity (ROP) as well as the associations of the ocular geometry with macular curvature in adults., Methods: The Gutenberg Prematurity Eye Study is a retrospective cohort study of preterm and full-term participants aged 18 to 52 years with a prospective ophthalmologic examination. The main outcome measure was the macular curvature in the central foveal optical coherence tomography (OCT) scan and its associations with gestational age (GA), birth weight and birth weight percentile, ROP occurrence, ROP treatment, and other perinatal factors were evaluated in univariable and multivariable linear regression analyses. Furthermore, a second model assessed the association of ocular geometry with macular curvature., Results: In the present study, 550 eyes of 284 adults born preterm and 277 eyes of 139 adults born full-term were examined (aged = 28.7 ± 8.7 years, 240 female subjects). In multivariable analyses for perinatal parameters, ROP treatment (B = -52.44, P = 0.023) and maternal smoking during pregnancy (B = 26.41, P = 0.019) showed an association with macular curvature. Regarding ocular geometric parameters, posterior segment length (B = 9.07, P < 0.001) and subfoveal choroidal thickness (B = -0.26, P < 0.001) were associated with macular curvature, central corneal thickness, anterior chamber depth, lens thickness, and foveal retinal thickness were not associated., Conclusions: Adults treated for ROP had relatively more negative curvature values compared to the full-term group, indicating a macular protrusion toward the vitreous cave. A thicker subfoveal choroidal thickness was associated with a flatter macular curvature, whereas a longer posterior segment length was associated with a steeper macular curvature indicating the characteristics of the myopic elongation of the eye.

Importance: In the neonatal intensive care unit, there is a lack of understanding about how best to communicate the prognosis of a serious complication to parents., Objective: To examine parental preferences and the effects of optimistic vs pessimistic message framing when providing prognostic information about a serious complication., Design, Setting, and Participants: This crossover randomized clinical trial was conducted at a single German university medical center between June and October 2021. Eligible participants were parents of surviving preterm infants with a birth weight under 1500 g. Data were analyzed between October 2021 and August 2022., Interventions: Alternating exposure to 2 scripted video vignettes showing a standardized conversation between a neonatologist and parents, portrayed by professional actors, about the prognosis of a hypothetical very preterm infant with severe intraventricular hemorrhage. The video vignettes differed in the framing of identical numerical outcome estimates as either probability of survival and probability of nonimpairment (optimistic framing) or a risk of death and impaired survival (pessimistic framing)., Main Outcomes and Measures: The primary outcome was preference odds (ratio of preference for optimistic vs pessimistic framing). Secondary outcomes included state anxiety, perceptions of communication, and recall of numerical estimates., Results: Of 220 enrolled parents (142 [64.5%] mothers; mean [SD] age: mothers, 39.1 [5.6] years; fathers, 42.7 [6.9] years), 196 (89.1%) preferred optimistic and 24 (10.1%) preferred pessimistic framing (preference odds, 11.0; 95% CI, 6.28-19.10; P < .001). Preference for optimistic framing was more pronounced when presented second than when presented first (preference odds, 5.41; 95% CI, 1.77-16.48; P = .003). State anxiety scores were similar in both groups at baseline (mean difference, -0.34; -1.18 to 0.49; P = .42) and increased equally after the first video (mean difference, -0.55; 95% CI, -1.79 to 0.69; P = .39). After the second video, state anxiety scores decreased when optimistic framing followed pessimistic framing but remained unchanged when pessimistic framing followed optimistic framing (mean difference, 2.15; 95% CI, 0.91 to 3.39; P < .001). With optimistic framing, participants recalled numerical estimates more accurately for survival (odds ratio, 4.00; 95% CI, 1.64-9.79; P = .002) but not for impairment (odds ratio, 1.50; 95% CI, 0.85-2.63; P = .16)., Conclusions and Relevance: When given prognostic information about a serious complication, parents of very preterm infants may prefer optimistic framing. Optimistic framing may lead to more realistic expectations for survival, but not for impairment., Trial Registration: German Clinical Trials Register (DRKS): DRKS00024466.

Purpose: Intrauterine growth restriction leading to a birth weight (BW) which is too low for gestational age (GA) is a known risk factor for various altered organ morphologies and dysfunction in later life. This study aimed to determine for the first time the effects of being small (SGA) or large for gestational age (LGA) on the ocular geometry of adults born at term., Methods: All participants were examined with optical biometry (LenStar 900, Haag Streit) to compare the corneal curvature, white-to-white distance, anterior chamber depth, lens thickness and axial length between former moderate (BW percentile 3rd to <10th) and severe (BW <3rd percentile) SGA, controls (BW 10th-90th percentile) and former moderate (BW >90th to 97th percentile) and severe (BW >97th percentile) LGA. Multivariable linear regression was used to analyse associations with GA, BW percentile categories, placental insufficiency, preeclampsia and breastfeeding after adjustment for age and sex., Results: In total, 589 eyes of 296 individuals born at term (aged 30.0 ± 9.4 years, 156 females) were examined, including 40 severe SGA, 38 moderate SGA, 140 with normal BW, 38 moderate LGA and 40 severe LGA. There was an association between a steeper corneal curvature with moderate (B = -0.201; p < 0.001) and severe SGA (B = -0.199; p < 0.001), with extreme SGA associated with smaller white-to-white (B = -0.263; p = 0.001) and a shorter axial length (B = -0.524; p = 0.031)., Conclusions: Severe and moderate prenatal growth restriction in adults born at term leads to an altered ocular geometry, namely a steepening of the cornea and a smaller corneal diameter., (© 2023 The Authors.

The Pediatric Intensive Care Unit Admissions (PIA) network aims to establish a nationwide database in Germany to gather epidemiological, clinical, and outcome data on pediatric critical illness. The heterogeneity of pediatric patients in intensive care units (PICU) poses challenges in obtaining sufficient case numbers for reliable research. Multicentered approaches, such as patient registries, have proven effective in collecting large-scale data. However, Germany lacks a systematic registration system for pediatric intensive care admissions, hindering epidemiological and outcome assessments. The PIA network intends to address these gaps and provide a framework for clinical and epidemiological research in pediatric intensive care. The network will interconnect PICUs across Germany and collect structured data on diagnoses, treatment, clinical course, and short-term outcomes. It aims to identify areas for improvement in care, enable disease surveillance, and potentially serve as a quality control tool. The PIA network builds upon the existing infrastructure of the German Pediatric Surveillance Unit ESPED and utilizes digitalized data collection techniques. Participating units will complete surveys on their organizational structure and equipment. The study population includes patients aged ≥28 days admitted to participating PICUs, with a more detailed survey for cases meeting specific criteria. Data will be collected by local PIA investigators, anonymized, and entered into a central database. The data protection protocol complies with regulations and ensures patient privacy. Quarterly data checks and customized quality reports will be conducted to monitor data completeness and plausibility. The network will evaluate its performance, data collection feasibility, and data quality. Eligible investigators can submit proposals for data analyses, which will be reviewed and analyzed by trained statisticians or epidemiologists. The PIA network aims to improve pediatric intensive care medicine in Germany by providing a comprehensive understanding of critical illness, benchmarking treatment quality, and enabling disease surveillance., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest.

Background: The present study aimed to investigate whether prematurity and perinatal stress exert long-term effects on the onset of panic disorder in later life., Methods: From 40,189 adults born in Germany between 1969 and 2002, a study cohort (n = 427) stratified by gestational age (GA) (extremely preterm: GA < 29 weeks; very preterm: GA 29-32 weeks; moderately preterm: GA 33-36 weeks; and full-term GA ≥ 37 weeks) was selected (age 28.5 ± 8.7 years). Multivariable logistic regression analyses were conducted to investigate associations between gestational age at birth and panic disorder adjusting for age, gender, socioeconomic status, and perinatal factors., Results: The prevalence of panic disorder was roughly equal in moderate to very preterm and full-term birth groups at 1.9%-3.8%. However, this rate significantly increased to 14.3% in the extreme preterm category (GA <2 9: 14.3 %, p = 0.002). In multivariable analyses, female gender and GA were independently associated with panic disorder. Adjusting for age, gender and socioeconomic status, panic disorder was associated with lower GA at birth (OR = 1.12 per week (CI95%: 1.01-1.26, p = 0.037). Whereas adjustment for nutrition status or indicators of perinatal stress had no effect, correction for the length of postnatal ICU-stay eliminated the association between preterm birth and later panic disorder., Limitations: Limitations include the small number of cases and the reliance on questionnaires to assess mental status., Conclusions: Prematurity likely increases the risk of panic disorder later in life, and the subsequent postnatal ICU-stay appears to be of critical importance. However, due to strong collinearity and other associated factors with preterm births, it remains unclear which is the primary determinant., Competing Interests: Declaration of competing interest The authors report no conflict of interest., (Copyright © 2023 The Authors.

Associations of preterm birth with later-life mental distress are well-established. A research gap concerns the role of psychosocial factors such as the family context. This study investigated associations of recalled parental rearing behavior with both preterm birth characteristics and psychological symptom burden later in life. Based on birth registry data of the Mainz University Hospital in Germany (infants born between 1969 and 2002) and using a selection algorithm, a cohort study comprising four gestational age (GA) strata was conducted (≥ 37 weeks: n = 138; 33-36 weeks: n = 132; 29-32 weeks: n = 106; ≤ 28 weeks: n = 132). Participants underwent a medical examination and completed standardized questionnaires. We investigated differences in dimensions of recalled parental rearing behavior according to GA and tested pre-/perinatal stress indicators and recalled parental rearing behavior as statistical predictors of depression and anxiety symptoms later in life. Lower GA was associated with more recalled emotional warmth and overprotection. Recalled emotional warmth was associated with fewer depression and anxiety symptoms, while recalled overprotection co-occurred with more depression symptoms. The findings indicate the relevance of parental rearing behavior for the offspring's mental health. As preterm birth implicates stress for the whole family requiring adaptive parental behavior, the latter could be an important modifiable risk factor., Competing Interests: Declaration of Competing Interest The authors have no conflicts of interest to declare., (Copyright © 2023 Elsevier B.V.

Background/aims: To evaluate whether anterior segment anatomy and axial length are associated with prematurity and perinatal factors in adults., Methods: The Gutenberg Prematurity Eye Study examined adults born preterm and term aged 18-52 years. All participants underwent a prospective ophthalmic examination (optical biometry via a LenStar 900, Haag-Streit) in Germany. The associations between gestational age (GA), birth weight (BW) and BW percentile, retinopathy of prematurity (ROP) occurrence, ROP treatment and other perinatal factors with the main outcome measures were evaluated by univariate and multivariable linear regression analyses. Main outcome measures were corneal radius, white-to-white distance, anterior chamber depth, lens thickness and axial length., Results: The study involved 861 eyes of 438 preterm and full-term individuals (aged 28.6±8.7 years, 245 females,). After adjustment for age and gender, a steeper corneal radius was associated with lower GA (B=0.02; p<0.001) and a lower BW percentile (B=0.003; p<0.001). A smaller white-to-white distance was linked to lower GA (B=0.02; p<0.001), a lower BW percentile (B=0.004; p<0.001) and postnatal ROP occurrence (B=-0.26; p<0.001). Decreased axial length was associated with lower GA at birth (B=0.05; p=0.002) and pre-eclampsia (B=-0.34; p=0.015). ROP-treated eyes had a shallower anterior chamber depth (B=-0.63; p=0.001) and increased lens thickness (B=0.64, p<0.001)., Conclusion: Our analyses in adults demonstrate that the corneal morphology is influenced by GA and BW percentile, while the anterior chamber depth and lens thickness are affected by ROP treatment, namely laser therapy and cryotherapy. The present study highlights that perinatal factors lead to lifelong sequelae of ocular shape., Competing Interests: Competing interests: AKS holds the professorship for ophthalmic healthcare research endowed by ‘Stiftung Auge’ and financed by ‘Deutsche Ophthalmologische Gesellschaft’ and ‘Berufsverband der Augenärzte Deutschlands e.V’.

Background: Children are often treated off-label and are at a disadvantage in pharmacotherapy. The aim of this study was to implement and evaluate a quality assurance measure (PaedPharm) for pediatric pharmacotherapy whose purpose is to reduce medication-related hospitalizations among children and adolescents., Methods: PaedPharm consisted of the digital pediatric drug information system PaedAMIS, pediatric pharmaceutical quality circles (PaedZirk), and an adverse drug event (ADE) reporting system (PaedReport). The intervention was implemented in a cluster-randomized trial (DRKS 00013924) in 12 regions, with a pediatric and adolescent medicine clinic in each and a total of 152 surrounding private practitioners, in 6 sequences over 8 quarters. In addition to the proportion of ADE-related hospital admissions (primary endpoint), comprehensive process evaluation included other endpoints such as coverage, user acceptance, and relevance to practice., Results: 41 829 inpatient admissions were recorded, of which 5101 were patients of physicians who participated in our study. 4.1% of admissions were ADE-related under control conditions, and 3.1% under intervention conditions (95% CI: [2.3; 5.9] and [1.8; 4.5], respectively). A model-based comparison yielded an intervention effect of 0.73 (population-based odds ratio; [0.39; 1.37]; p = 0.33). PaedAMIS achieved moderate user acceptance and PaedZirk achieved high user acceptance., Conclusion: The introduction of PaedPharm was associated with a decrease in medication-related hospitalizations that did not reach statistical significance. The process evaluation revealed broad acceptance of the intervention in outpatient pediatrics and adolescent medicine.

Objective: Children with special health care needs (SHCN) due to a chronic health condition perform more poorly at school compared to their classmates. There is still little knowledge on the causal pathways and which factors could be targeted by interventions. We, therefore, investigated school absenteeism in children with SHCN compared to their peers., Methods: This study was based on data from the German population-based prospective cohort study ikidS (German for: I will start school). Children with SHCN were identified by the Children with Special Health Care Needs screener that captures five consequences of physical or mental chronic health conditions: (1) use or need of prescription medication, (2) above average use or need of medical, mental health, or educational services, (3) functional limitations compared with others of the same age, (4) use or need of specialized therapies, and (5) treatment or counseling for emotional, behavioral, or developmental problems. School absenteeism was defined as days absent from school due to illness during first grade and was reported by classroom teachers. Associations between SHCN consequences and school absenteeism were investigated by negative binomial regression models. Effect estimates were adjusted for confounding variables identified by a causal framework and directed acyclic graphs., Results: 1,921 children (mean age at follow-up 7.3 years, standard deviation 0.3; 49% females) were included; of these, 14% had SHCN. Compared to their classmates, children with SHCN had more days absent (adjusted rate ratio: 1.37; 95% confidence interval 1.16, 1.62). The effect was strongest among children with i) functional limitations, ii) treatment or counseling for emotional, behavioral, or developmental problems, and iii) those who experienced two or more SHCN consequences., Conclusions: Children with SHCN have higher school absenteeism, which could-at least partly-explain their poorer school performance and lower educational attainment. SHCN-specific targeted interventions may reduce the adverse effects of SHCN on educational outcomes in children., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2023 Schlecht et al.

Objectives: This study investigated the effects of prematurity and ROP on visual acuity and VRQoL in adults (18-52 years)., Methods: The Gutenberg Prematurity Eye Study is a retrospective cohort study with a prospective ophthalmologic examination. Preterm and full-term participants at an age from 18 to 52 years were included. Distant corrected visual acuity (DCVA) and VRQoL were assessed in participants (892 eyes of 450 individuals aged 28.6 ± 8.6 years, 251 females) grouped into full-term controls (gestational age [GA] at birth ≥37 weeks), preterm participants without ROP and GA 33-36 weeks (group 2), GA 29-32 weeks (group 3), GA ≤ 28 weeks (group 4), non-treated ROP (group 5) and treated ROP (group 6). Main outcome measures were distant corrected visual acuity (DCVA), VRQoL and prevalence of amblyopia., Results: The DCVA of the better eye correlated (p < 0.001) with GA, birth weight, ROP, ROP treatment, and perinatal adverse events and was poorer in both ROP groups. Visual acuity of <20/200 in the better eye was observed in two participants (4.2%) in the ROP group and one person (6.7%) in the treated ROP group. The prevalence of amblyopia increased in the ROP groups. Compared to full-term controls, visual functioning VRQoL scores were lower in preterm individuals independent of ROP while socioemotional VRQoL scores were only lower in the treated ROP group., Conclusion: Participants with postnatal ROP and its treatment showed decreased visual acuity and VRQol in adulthood, with amblyopia occurring more frequently in more preterm participants with ROP., (© 2022.

Background: Prematurity and the presence of retinopathy of prematurity (ROP) increase the risk for the occurrence of amblyogenic risk factors in childhood and adolescence., Aim: The aim of the present study was to evaluate ocular morbidities and the ophthalmological care of former preterm and full-term persons in adulthood., Material and Methods: The Gutenberg prematurity eye study (GPES) is a retrospective cohort study with a prospective ophthalmological examination of individuals formerly born preterm and full term between 1969 and 2002 (now aged 18-52 years). All participants underwent a detailed ophthalmological examination and were asked about the frequency of ophthalmological care. Participants were grouped into those with normal gestational age (GA) ≥ 37 weeks (control group), preterm individuals without ROP and GA 33-36 weeks (group 2), GA 29-32 weeks (group 3), GA ≤ 28 weeks (group 4), and those with ROP without treatment (group 5) and with ROP with treatment (group 6). All participants were asked if they had an ophthalmological examination within the last 12 months., Results: In total, data from 140 term and 310 preterm adults were included in the present study. Strabismus was present in 2.1 % (3/140), 6.6 % (9/137), 17.4 % (16/92), 11.1 % (2/18), 27.1 % (13/48) and 60 % (9/15) in groups 1-6, respectively. The proportion of subjects with an ophthalmological examination within the last 12 months was highest in the groups of extremely preterm persons with and without ROP compared with the control group. Overall, 33.3 % (1/3) of the term and 57.1 % (28/49) of the preterm subjects with strabismus and 0 % (0/3) of the term and 46.9 % (15/32) of the preterm individuals with amblyopia had an ophthalmological examination within the past 12 months., Discussion: Extremely preterm adults with and without postnatal ROP showed the highest rate of eye diseases as well as the highest rate of ophthalmological check-ups within the last 12 months. This suggests that extremely preterm adults particularly with the occurrence of postnatal ROP perceive more frequent ophthalmological check-ups throughout their lives., (© 2022. The Author(s).)

Purpose: Prematurity, prenatal growth restriction, and retinopathy of prematurity (ROP) are associated with altered ocular geometry, such as a steeper corneal shape in childhood, but it is unclear whether perinatal history affects corneal thickness development, so this study investigated whether corneal thickness in adulthood is affected by perinatal history., Marterials and Methods: The Gutenberg Prematurity Eye Study (GPES) is a retrospective cohort study with a prospective ophthalmologic examination in Germany. The corneal thickness was measured by Scheimpflug imaging (Pentacam HR, Oculus Optikgeräte GmbH, Wetzlar, Germany), and the relationship between perinatal parameters respective birth weight percentile and corneal thickness at different locations was assessed using uni- and multivariable linear regression models. Covariates included age, sex, mean corneal radius, white-to-white distance, gestational age, birth weight percentile, ROP occurrence, and treatment. The main outcome measures were corneal thickness at the apex, the pupil center, and the corneal periphery., Results: The corneal thickness was measured in 390 participants (754 eyes, mean age 29.7+/-8.7 years, 224 females). In multivariable analyses, a lower birth weight percentile was associated with a lower corneal thickness at the apex (B = 0.20, p = 0.003) and the pupil (B = 0.19, p = 0.007). These effects diminished towards the corneal periphery and were not observed beyond the 4-mm diameter circle around the thinnest corneal position. Neither gestational age, ROP occurrence, or ROP treatment affected the corneal thickness., Conclusion: A lower birth weight percentile in subjects born preterm as a proxy for restricted fetal growth is associated with corneal thickness thinning in adults aged 18 to 52 years, indicating that corneal thickness development, particularly in the corneal center, may originate in the fetal stage., Competing Interests: Conflict of interest The author reports no conflict of interest., (Copyright © 2022 Spanish General Council of Optometry.

Background: The aim of the present study was to evaluate the ophthalmologic care in childhood and adolescence of infants born preterm and full-term from the retrospective point of view of their parents., Methodology: The Gutenberg Prematurity Eye Study (GPES) is a retrospective cohort study with a prospective ophthalmologic examination of persons born preterm and full-term between 1969 and 2002 (now aged 18 to 52 years), and asks their parents about the ophthalmologic care received by their children in childhood and adolescence from their retrospective perspective. Participants and their parents were grouped into those with normal gestational age (GA) ≥ 37 (control group), preterm born infants without retinopathy of prematurity (ROP) and gestational age (GA) 33 - 36 (group 2), GA 29 - 32 (group 3), GA ≤ 28 weeks (group 4), and those with ROP without treatment (group 5) and with ROP with treatment (group 6). Parents of participants were interviewed about the ophthalmic care received by their children., Results: In total, data from 57 full-term and 131 preterm infants and their parents were included in the present study. The parents of the participants reported that ophthalmologic examination had taken place until 6 years of age in the respective groups 1 to 6 in 22/57 (38.6%), 33/58 (56.9%), 22/38 (57.9%), 3/6 (50%), 19/21 (90.5%), and 7/8 (87.5%). Overall, between 83% and 100% of parents in the different groups reported that ophthalmologic care had been adequate. A change of ophthalmologist due to dissatisfaction with treatment was reported by a total of 4/57 (7%), 9/58 (15.5%), 8/38 (21.1%), 1/6 (16.7%), 1/21 (4.8%) and 2/8 (25%) in the respective groups., Discussion: The present study demonstrates adequate satisfaction and good treatment regarding ophthalmologic care of former preterm children from the parents' perspective.

Psychotropic drugs are frequently prescribed 'off-label' to children and adolescents and carry the risk of serious adverse drug reactions (sADR). We examined the frequency of sADRs of psychotropic drugs in pediatric inpatients and explored their potential preventability through following the recommendations of a web-based pediatric drug information system (PDIS). The potential socio-economic impacts of using this online system is also addressed. Routine clinical data from all inpatients treated in a child and adolescent psychiatry department between January 2017 and December 2018 were retrospectively examined for the occurrence of sADRs as defined by the European Medicines Agency. The preventability of the sADRs was assessed based on the information of the PDIS. Furthermore, the expected prolongation of the hospital stay due to sADRs was calculated as well as the associated treatment costs. The study was supported by the Innovation Fund of the Joint Federal Committee, grant number 01NVF16021. In total, 1036 patients were screened of whom 658 (63.5%) received psychopharmacological treatment. In 53 (8.1%) of these patients 54 sADRs were documented, of which 37 sADRs were identified as potentially preventable through PDIS. Mitigating sADR through PDIS would likely have prevented prolonged hospital stays and conferred considerable savings for health insurance companies. PDIS provides systematic and evidence-based information about pediatric psychopharmacotherapy and helps to prevent prescribing errors. Therefore, PDIS is a useful tool to increase drug therapy safety in child and adolescent psychiatry. Further prospective studies are needed to confirm the results., (© 2022. The Author(s).)

Purpose: Low birth weight (BW) is associated with increased corneal aberrations in childhood and alterations of corneal geometry in adulthood. Increased corneal aberrations may be a factor contributing to decreased visual function in former low BW newborns in later life. Hence, the aim of this study was to analyze the long-term effect of low BW on corneal aberrations in adulthood., Methods: In the German population-based Gutenberg Health Study (GHS) participants (age: 40-80 years) were examined with Scheimpflug imaging (Pentacam HR, Oculus Optikgeräte GmbH, Wetzlar, Germany). The relationship between self-reported BW and the different types of corneal aberrations was analyzed using linear regression analysis as uni- and multivariable analysis with adjustment for potential confounders. The main outcome measures were corneal aberrations defined as astigmatism (Z 2 -2 ; Z 2 2 ), coma (Z 3 -1 ; Z 3 1 ), trefoil (Z 3 -3 ; Z 3 3 ), spherical aberration (Z 4 0 ) and root-mean square of higher order aberrations (HOA; 3rd up to 8th order; aperture size: 6 mm)., Results: Overall, 5,628 participants were included in this analysis (3,004 women, aged 56.0 +/- 10.3 years). In a multivariable analysis lower BW was associated with decreased horizontal trefoil (B = 0.004 [0.001; 0.006] µm/500 g; p=.008); higher spherical aberrations (B=-0.006 [-0.008;-0.003] µm/500 g; p<.001), higher RMS (B=-0.028 [-0.042;-0.014] µm/500 g; p<.001), increased HOA (B=-0.007 [-0.010;-0.003] µm/500 g; p<.001) and increased LOA (B=-0.027 [-0.041;-0.013] µm/500 g; p<.001). No association was observed between birth weight and the other types of corneal aberrations in multivariable model., Conclusion: Our results indicate an association between BW and spherical aberration in adults aged 40 to 80 years. This indicates that low BW may have an association with an altered corneal shape development which may affect optical image quality and, hence, visual function., Competing Interests: Conflict of interest The author reports no conflict of interest.

Introduction: Participation is an important dimension of healthy child development and is associated with higher self-rated health, educational attainment and civic engagement. Many children with special healthcare needs (SHCN) experience limited participation and are thus at risk for adverse health and developmental outcomes. Despite this, interventions that promote participation in healthcare are scarce. We therefore evaluate the effectiveness of a complex age- and condition-generic intervention that strengthens participation-centred care involving parents and their children with SHCN by, inter alia , assessing preferences, specifying participation goals and facilitating shared decision-making in care., Methods and Analysis: In this study protocol we describe the design and procedures for an unblinded, stepped wedge, cluster randomised trial conducted in 15 German interdisciplinary healthcare facilities providing services for children aged 0-18 years with SHCN. Sites are randomised to five periods in which they switch from control to intervention condition in blocks of three. The intervention includes: (1) team training focused on participation-centred care, (2) introduction of a new software facilitating participation-focused documentation and (3) implementation support promoting the transfer of training content into routine care. Study sites deliver routine care while in the control condition. As primary outcome, the degree of perceived shared decision-making with parents (CollaboRATE pediatric parent scale), a potential antecedent of achieving participation goals in everyday life, is assessed on one randomly selected day per week during the entire study period, directly following care appointments. We aim to sample 70 parents per study site and period. Additionally, participation of children is assessed within a closed embedded cohort with three parent and patient surveys. Intervention effectiveness will be modelled with a marginal model for correlated binary outcomes using generalised estimation equations and complete cases. A comprehensive mixed-methods process evaluation complements the effectiveness analyses.
