Extraintestinal Manifestations in Patients with Inflammatory Bowel Disease: Study Based on the ENEIDA Registry.

BACKGROUND: Patients with inflammatory bowel disease (IBD) may present extraintestinal manifestations (EIMs) that affect the joints, skin, eyes, and hepatobiliary area, among others. AIMS: Our aim was to analyse the prevalence and characteristics of EIMs in patients with IBD and to identify the possible risk factors associated with the development of EIMs in the largest series published to date. METHODS: Observational, cross-sectional study including patients from the Spanish ENEIDA registry promoted by GETECCU. We retrospectively identified all cases of EIMs in the ENEIDA registry until January 2018. RESULTS: The study included 31,077 patients, 5779 of whom had at least one EIM (global prevalence 19%; 95% CI 18.2-19.0). Among the different types of EIMs, rheumatic manifestations had a prevalence of 13% (95% CI 12.9-13.7; 63% of EIMs), with a prevalence of 5% (95% CI 4.7-5.2) for mucocutaneous manifestations, 2.1% (95% CI 1.9-2.2) for ocular manifestations, and 0.7% (95% CI 0.6-0.8) for hepatobiliary manifestations. The multivariable analysis showed that the type of IBD (Crohn's disease, p < 0.001), gender (female, p < 0.001), the need for an immunomodulator (p < 0.001) or biologic drugs (p < 0.001), a previous family history of IBD (p < 0.001), and an extensive location of IBD (p < 0.001) were risk factors for the presence of EIMs. CONCLUSIONS: One-fifth of patients with IBD may have associated EIMs, with rheumatic manifestations as the most frequent (> 60% of EIMs). Female patients with severe Crohn's disease represent the group with the highest risk of developing EIMs. These patients should therefore be specially monitored and referred to the corresponding specialist when suggestive symptoms appear.

Changes in objectively measured sleep after a multidisciplinary lifestyle intervention in children with abdominal obesity: A randomized trial.

BACKGROUND/OBJECTIVE: childhood obesity and sleep disorders have a well-established cross-sectional association, but lifestyle interventions' effects on sleep quality remain under-researched. This study aimed to evaluate the sleep quality of 122 participants (7-16 years) with abdominal obesity after a 2-year necessary lifestyle intervention. PATIENTS/METHODS: participants were assigned to either the intervention group (moderate hypocaloric Mediterranean Diet) or the usual care group (standard recommendations on a healthy diet). Sleep was objectively assessed using triaxial accelerometry, and sleep parameters analyzed included latency, efficiency, wake after sleep onset, total time in bed, total sleep time, number of awakenings, and awakening duration. RESULTS AND CONCLUSIONS: the results showed that the intervention group significantly improved sleep latency at 12 and 24 months and improved sleep efficiency at 2 and 12 months, compared to the usual care group. Wake after sleep onset and the number of awakenings were significantly reduced at 24 months in the intervention group. Wake after sleep onset and leptin levels were positively associated in all participants. Total time in bed was inversely associated with triglycerides and metabolic score, and total sleep time was inversely associated with leptin, triglycerides, and metabolic score after the 2-month intervention. Triglyceride levels were inversely associated with total time in bed and total sleep time at one year, while the metabolic score was directly associated with wake after sleep onset and the number of awakenings and inversely associated with efficiency. In conclusion, the multidisciplinary intervention in children and adolescents with abdominal obesity reduced anthropometric parameters and improved sleep habits.

Clinical Value of NGS Genomic Studies for Clinical Management of Pediatric and Young Adult Bone Sarcomas.

Genomic techniques enable diagnosis and management of children and young adults with sarcomas by identifying high-risk patients and those who may benefit from targeted therapy or participation in clinical trials. Objective: to analyze the performance of an NGS gene panel for the clinical management of pediatric sarcoma patients. We studied 53 pediatric and young adult patients diagnosed with sarcoma, from two Spanish centers. Genomic data were obtained using the Oncomine Childhood Cancer Research Assay, and categorized according to their diagnostic, predictive, or prognostic value. In 44 (83%) of the 53 patients, at least one genetic alteration was identified. In 80% of these patients, the diagnosis was obtained (n = 11) or changed (n = 9), and thus genomic data affected therapy. The most frequent initial misdiagnosis was Ewing's sarcoma, instead of myxoid liposarcoma (FUS-DDDIT3), rhabdoid soft tissue tumor (SMARCB1), or angiomatoid fibrous histiocytoma (EWSR1-CREB1). In our series, two patients had a genetic alteration with an FDA-approved targeted therapy, and 30% had at least one potentially actionable alteration. NGS-based genomic studies are useful and feasible in diagnosis and clinical management of pediatric sarcomas. Genomic characterization of these rare and heterogeneous tumors also helps in the search for prognostic biomarkers and therapeutic opportunities.

Somatic and germline analysis of a familial Rothmund-Thomson syndrome in two siblings with osteosarcoma.

Rothmund-Thomson syndrome (RTS) is characterized by a rash that begins in the first few months of life and eventually develops into poikiloderma. Associated symptoms are alterations in the teeth, sparse hair, thin eyebrows, lack of eyelashes, low stature, bone abnormalities, hematological illnesses, gastrointestinal disease, malnutrition, cataracts, and predisposition to cancer, principally to bone tumors and skin cancer. Diagnostic certitude is provided by a genetic study involving detection of pathogenic variants of the RECQL4 gene. We hereby present a familiar case of RTS in two siblings from a Portuguese family, both diagnosed with osteosarcoma. Genomic analysis (203 genes) of both tumors as well as germline analysis of the RECQL4 gene, thus confirming the syndrome in the family, have been performed. The relevance of clinical recognition of the hallmarks of the disease and thus early diagnosis with early intervention is highlighted.
