BACKGROUND AND AIMS: Dysregulation of inflammatory and immune responses has been implicated in the pathogenesis of heart failure (HF). But even if inflammation is a prerequisite for inflammatory bowel disease (IBD), little is known about HF risk in IBD. METHODS: In this Swedish nationwide cohort, patients with biopsy-confirmed IBD were identified between 1969 and 2017 [n = 81,749, Crohn's disease (CD, n = 24,303), ulcerative colitis (UC, n = 45,709), and IBD-unclassified (IBD-U, n = 11,737)]...

Hypomyelinating leukodystrophy (HLD) is an autosomal recessive disorder characterized by defective central nervous system myelination. Exome sequencing of two siblings with severe cognitive and motor impairment and progressive hypomyelination characteristic of HLD revealed homozygosity for a missense single-nucleotide variant (SNV) in EPRS1 (c.4444 C > A; p.Pro1482Thr), encoding glutamyl-prolyl-tRNA synthetase, consistent with HLD15. Patient lymphoblastoid cell lines express markedly reduced EPRS1 protein due to dual defects in nuclear export and cytoplasmic translation of variant EPRS1 mRNA...

OBJECTIVE: This study aims to assess the familial aggregation of traffic risky behaviours among pedestrians and describe the sociodemographic profile of pedestrians in northwestern Iran. METHODS: A cross-sectional study was conducted among 933 pedestrians in 2023. Participants were selected using stratified random sampling. Traffic risky behaviour was measured using a validated instrument among heads of households and their first relatives. The generalised estimating equations were computed to estimate the adjusted OR and 95% CI for familial aggregation of traffic risky behaviours...

PURPOSE: We investigated whether longitudinally assessed physical activity (PA) and adherence specifically to World Health Organization PA guidelines mitigates or moderates mortality risk regardless of genetic liability to cardiovascular disease (CVD). We also estimated the causality of the PA-mortality association. METHODS: The study used the older Finnish Twin Cohort (FTC) with 4,897 participants aged 33-60 years (54.3% women). Genetic liability to coronary heart disease, systolic and diastolic blood pressure was estimated with polygenic risk scores (PRSs) derived from the Pan-UK Biobank (N ≈ 400,000; > 1,000,000 genetic variants)...

UNLABELLED: Phototherapy (PT) is a widely used treatment for neonatal jaundice, yet the ideal model of application remains controversial. In this study, the effects of continuous phototherapy (CPT) and intermittent phototherapy (IPT) models were compared in the treatment of neonatal indirect hyperbilirubinemia (IHB) and whether IPT is a superior modality is investigated. Single-centre parallel randomized controlled open label trial. A computer-based table of random numbers was used to allocate treatments...

PURPOSE: The function of FAM177A1 and its relationship to human disease is largely unknown. Recent studies have demonstrated FAM177A1 to be a critical immune-associated gene. One previous case study has linked FAM177A1 to a neurodevelopmental disorder in four siblings. METHODS: We identified five individuals from three unrelated families with biallelic variants in FAM177A1. The physiological function of FAM177A1 was studied in a zebrafish model organism and human cell lines with loss-of-function variants similar to the affected cohort...

Coding de novo mutations (DNMs) contribute to the risk for autism spectrum disorders (ASD), but the contribution of noncoding DNMs remains relatively unexplored. Here we use whole genome sequencing (WGS) data of 12,411 individuals (including 3,508 probands and 2,218 unaffected siblings) from 3,357 families collected in Simons Foundation Powering Autism Research for Knowledge (SPARK) to detect DNMs associated with ASD, while examining Simons Simplex Collection (SSC) with 6383 individuals from 2274 families to replicate the results...

BACKGROUND: Cardiomyopathy caused by aggregation and deposition of transthyretin amyloid fibrils in the heart (ATTR-CM) is divided into a hereditary (ATTRv) and a wild-type (ATTRwt) forms. While ATTR-CM has been considered a rare disease, recent studies suggest that it is severely underdiagnosed and an important cause of heart failure in elderly patients. Familial occurrence is implicit in ATTRv, but it is not expected in ATTRwt. CASE SUMMARY: We report a case series of two unrelated families each with two brothers diagnosed with ATTRwt...

AIMS: To identify N-glycan structures on immunoglobulin A related to type 1 diabetes mellitus among children at the disease onset and adults with type 1 diabetes mellitus. METHODS: Human polyclonal IgA N-glycans were profiled using hydrophilic interaction ultra performance liquid chromatography in two cohorts. The first cohort consisted of 62 children at the onset of type 1 diabetes mellitus and 86 of their healthy siblings. The second cohort contained 84 adults with the disease and 84 controls...

INTRODUCTION: Telemetric monitoring of intracranial pressure (ICP) in children with a complex cerebrospinal disorder might help parents distinguish acute and potential life-threatening symptoms of hydrocephalus from other illnesses. RESEARCH QUESTION: What is patient and parent perceptions of system utility of telemetric ICP monitoring, and how does a long-term telemetric implant influence daily life of both patients and their families? MATERIAL AND METHODS: A qualitative case study design with a focus group interview including parents of children with a complex cerebrospinal fluid disorder and an implanted telemetric ICP sensor...

De novo germline pathogenic variants (gPV) of the BReast CAncer 1 (BRCA1) gene are very rare. Only a few have been described up to date, usually in patients with a history of ovarian or breast cancer. Here, we report the first case of an incidental de novo BRCA1 germline pathogenic variant which was identified within the framework of the Plan France Médecine Génomique (PFMG) 2025 French national tumor sequencing program. The proband was a 29-year-old man diagnosed with metastatic osteosarcoma. Tumor whole exome sequencing identified a BRCA1 c...

Prenatal antidepressant exposure has been reported to be associated with adverse neurodevelopmental outcomes, yet studies considering confounding factors in Asian populations are lacking. This study utilized a nationwide data base in Taiwan, enrolling all liveborn children registered in the National Health Insurance system between 2004 and 2016. Subjects were divided into two groups: antidepressant-exposed (n = 55,707)) and antidepressant-unexposed group (n = 2,245,689). The effect of antidepressant exposure during different trimesters on autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD) was examined...

PURPOSE: When a child needs a hematopoietic stem cell transplant, the seriousness of the child's illness is highlighted. The purpose of this study was to explore parents' experiences of the transplantation process when two children in the family are involved, one severely ill child as the recipient and the other as the donor. METHODS: In this qualitative study, interviews were conducted with 18 parents of 13 healthy minor donors after successful stem cell transplants...

Prevalence estimates of sibling bullying indicate it occurs more frequently and with more negative consequences than peer bullying, yet many countries do not track or investigate the phenomenon. University students from Argentina, Estonia, and the United States were surveyed to investigate their retrospective experiences involving sibling bullying, how often it occurred, the roles held, and the forms communicated. In the aggregated data, roughly 50 % of the sampled emerging adults (N = 3477) reported experience with sibling bullying, with the dual role of bully-victim being the most frequently reported role held by males and females, with the second role being bully for males and victim for females...

Supportive peers are crucial for transgender children's well-being. Transgender children who live in their affirmed gender face decisions surrounding concealment and disclosure of their transgender identity. We sought to understand how cisgender (N = 115) and gender-diverse children (N = 127), and siblings of gender-diverse children (N = 63) think about transition disclosure and concealment. All groups viewed transition disclosure and concealment positively. However, gender-diverse children showed greater acceptance of transition concealment and had stronger liking of transition concealers (relative to non-transition concealers)...

Homo sapiens and Neanderthals underwent hybridization during the Middle/Upper Paleolithic age, culminating in retention of small amounts of Neanderthal-derived DNA in the modern human genome. In the current study, we address the potential roles Neanderthal single nucleotide polymorphisms (SNP) may be playing in autism susceptibility in samples of black non-Hispanic, white Hispanic, and white non-Hispanic people using data from the Simons Foundation Powering Autism Research (SPARK), Genotype-Tissue Expression (GTEx), and 1000 Genomes (1000G) databases...

The term "Gilles de la Tourette syndrome", or the more commonly used term "Tourette syndrome" (TS) refers to the association of motor and phonic tics which evolve in a context of variable but frequent psychiatric comorbidity. The syndrome is characterized by the association of several motor tics and at least one phonic tic that have no identifiable cause, are present for at least one year and appear before the age of 18. The presence of coprolalia is not necessary to establish or rule out the diagnosis, as it is present in only 10% of cases...

Monocytes are immune regulators implicated in the pathogenesis of type 1 diabetes (T1D), an autoimmune disease that targets insulin-producing pancreatic β cells. We determined that monocytes of recent onset (RO) T1D patients and their healthy siblings express proinflammatory/cytolytic transcriptomes and hypersecrete cytokines in response to lipopolysaccharide exposure compared to unrelated healthy controls (uHCs). Flow cytometry measured elevated circulating abundances of intermediate monocytes and >2-fold more CD14+ CD16+ HLADR+ KLRD1+ PRF1+ NK-like monocytes among patients with ROT1D compared to uHC...

BACKGROUND: Children with medical complexity (CMC) represent a heterogeneous group of children with multiple, chronic healthcare conditions. Caregivers of CMC experience a high intensity of caregiving that is often variable, extends across several networks of care, and often lasts for the entirety of the child's life. The economic impacts of caregiving are yet understudied in the CMC context. There have been recognized limitations to the sole use of quantitative methods when developing economic models of disease because they lack direct caregiver voice and context of caregiving activities and existing methods have been noted to be ableist...

As cases of type 1 diabetes mellitus (T1DM) increase, so do their impact on sibling relationships. This literature review of four databases from 2010 to 2024 discusses findings from five studies and the themes that emerged: education needs and family functioning. Improvements in family-centered care and education are needed for siblings of children with T1DM.
