Early-life menstrual characteristics and gestational diabetes in a large US cohort.

Background: Associations between early-life menstrual cycle characteristics (MCC) and gestational diabetes (GDM) remain unclear.

Objectives: To evaluate associations between early-life MCCs and GDM in first pregnancy, across pregnancies and its recurrence.

Methods: This analysis included participants from a US-based digital cohort enrolled between 11/2019 and 9/2023 who provided consent, completed relevant surveys, were without diabetes and aged ≥18 at first pregnancy (n = 30,473).

Accuracy of Screening Tests for the Diagnosis of Urinary Tract Infections in Young Children.

Background: The objective of this study was to compare the accuracy of available tests for pyuria, including newer automated tests, and to examine the implications of requiring them for the diagnosis of urinary tract infections (UTIs).

Methods: We included children between 1 and 36 months of age undergoing bladder catheterization for suspected UTIs who presented to 1 of 3 pediatric centers. Using a positive urine culture result as the reference standard, we compared the sensitivity of 5 modalities for assessing pyuria at the cutoffs most often used clinically for detecting children with a positive culture result: leukocyte esterase on a dipstick, white blood cell (WBC) count on manual microscopy with and without using a hemocytometer, automated WBC enumeration using flow cytometry, and automated WBC enumeration using digital imaging with particle recognition.

Experiences and impact of moral injury in human trafficking survivors: a qualitative study.

Background: Research in recent years has increasingly highlighted the relationship between exposure to potentially morally injurious events (PMIEs) and poor mental health outcomes. Human trafficking survivors often report exposure to many traumatic and PMIEs and given the complexities of trafficking exploitation, survivors may be especially vulnerable to moral injury. Despite this, no research has investigated experiences of PMIEs and moral injury in human trafficking survivors.

Cyclic Vomiting Syndrome in Patients Affected by Jansen-de Vries Syndrome: Results From an International Survey.

Jansen-de Vries syndrome (JdVS) is an autosomal dominant neurodevelopmental disorder with intellectual disability and gastrointestinal (GI) abnormalities, including recurrent vomiting. This study aimed to understand the frequency and severity of GI symptoms in JdVS patients and to investigate the potential association with cyclic vomiting syndrome (CVS), which has not been previously reported. An international online survey assessed the prevalence and features of CVS and GI disorders in JdVS patients using Rome IV Criteria.

Biofunctionalized gelatin hydrogels support development and maturation of iPSC-derived cortical organoids.

Human neural organoid models have become an important tool for studying neurobiology. However, improving the representativeness of neural cell populations in such organoids remains a major effort. In this work, we compared Matrigel, a commercially available matrix, to a neural cadherin (N-cadherin) peptide-functionalized gelatin methacryloyl hydrogel (termed GelMA-Cad) for culturing cortical neural organoids.
