Pediatric ICU Admissions After Adolescent Suicide Attempts During the Pandemic.

BACKGROUND AND OBJECTIVES: The worldwide severe acute respiratory syndrome coronavirus 2 pandemic challenges adolescents' mental health. In this study, we aim to compare the number of pediatric ICU (PICU) admissions after suicide attempts during the first German lockdown and one year later during a second, prolonged lockdown with prepandemic years. METHODS: A retrospective multicenter study was conducted among 27 German PICUs. Cases <18 years admitted to the PICU because of accidents or injuries between March 16 and May 31 of 2017 to 2021 were identified based on International Classification of Diseases, 10th Revision codes (German modification) and patient data entered into a database. This study is a subset analysis on suicide attempts in adolescents aged 12 to 17.9 years. The Federal Statistics Office was queried for data on fatal suicides, which were available only for 2020 in adolescents aged 10 to 17.9 years. RESULTS: Total admissions and suicide attempts declined during the first lockdown in 2020 (standardized morbidity ratio 0.74 (95% confidence interval; 0.58-0.92) and 0.69 (0.43-1.04), respectively) and increased in 2021 (standardized morbidity ratio 2.14 [1.86-2.45] and 2.84 [2.29-3.49], respectively). Fatal suicide rates remained stable between 2017 to 2019 and 2020 (1.57 vs 1.48 per 100 000 adolescent years) with monthly numbers showing no clear trend during the course of 2020. CONCLUSIONS: This study shows a strong increase in serious suicide attempts among adolescents during the course of the pandemic in Germany. More research is needed to understand the relation between pandemic prevention measures and suicidal ideation to help implement mental health support for adolescents.

Impact of the First COVID Lockdown on Accident- and Injury-Related Pediatric Intensive Care Admissions in Germany-A Multicenter Study.

Children's and adolescents' lives drastically changed during COVID lockdowns worldwide. To compare accident- and injury-related admissions to pediatric intensive care units (PICU) during the first German COVID lockdown with previous years, we conducted a retrospective multicenter study among 37 PICUs (21.5% of German PICU capacities). A total of 1444 admissions after accidents or injuries during the first lockdown period and matched periods of 2017-2019 were reported and standardized morbidity ratios (SMR) were calculated. Total PICU admissions due to accidents/injuries declined from an average of 366 to 346 (SMR 0.95 (CI 0.85-1.05)). Admissions with trauma increased from 196 to 212 (1.07 (0.93-1.23). Traffic accidents and school/kindergarten accidents decreased (0.77 (0.57-1.02 and 0.26 (0.05-0.75)), whereas household and leisure accidents increased (1.33 (1.06-1.66) and 1.34 (1.06-1.67)). Less neurosurgeries and more visceral surgeries were performed (0.69 (0.38-1.16) and 2.09 (1.19-3.39)). Non-accidental non-suicidal injuries declined (0.73 (0.42-1.17)). Suicide attempts increased in adolescent boys (1.38 (0.51-3.02)), but decreased in adolescent girls (0.56 (0.32-0.79)). In summary, changed trauma mechanisms entailed different surgeries compared to previous years. We found no evidence for an increase in child abuse cases requiring intensive care. The increase in suicide attempts among boys demands investigation.

Fecal calprotectin concentrations in premature infants have a lower limit and show postnatal and gestational age dependence.

BACKGROUND: There is a need for reliable diagnostic biomarkers in necrotizing enterocolitis (NEC). Whereas fecal calprotectin (fCP) has been reported to have insufficient sensitivity and specificity, no previous study has stratified for gestational and postnatal age. OBJECTIVE: We aimed to provide developmental specific fCP data in premature infants and to analyze its value in detecting intestinal distress and episodes of NEC. METHODS: Between April 2008 and December 2009, 1,899 fecal samples were obtained from 206 very low birth weight infants. RESULTS: Mean gestational age (GA) was 28.5 weeks and birth weight 1,057 g. 19 (9.2%) patients developed NEC stage II+, of whom 5 had fulminant NEC with unusually low fCP concentrations in meconium and afterwards. fCP levels showed significant gestational and postnatal age dependent dynamics with particularly low levels in extremely premature infants. In infants with a GA <26 + 1 weeks using GA-adapted reference values, the sensitivity for discriminating moderate NEC from healthy infants and infants with intestinal distress was 0.89 for a cut-off of 180 and 210 µg/g, respectively, at onset of symptoms. Specificity was 0.96 and 0.84. Fulminant NEC was characterized by unusually low fCP concentrations with a cut-off of <24 µg/g having a sensitivity of 0.84 and a specificity of 0.72 for identifying those cases. CONCLUSIONS: fCP levels depend on gestational and postnatal age and in contrast to adults, there is a lower limit in premature infants. Taking these observations into account when defining reference values and interpreting fCP data in the clinical context, fCP can be a useful marker in identifying premature infants with gastrointestinal distress and NEC in particular.
