While children with worse middle ear disease are more likely to receive more tubes and have long-term conductive hearing loss as a result of ear disease, the results of this study suggest that multiple tube placements may not contribute to improved long-term hearing outcomes. Further research focusing on long-term outcomes is needed to establish patient-centered criteria guiding decision making for ventilation tube placement in children with cleft palate.

Aim We investigated the relation of time of onset and length of obesity with biomarkers of β‐cell function in early adulthood in an infancy cohort. Material and methods In 1039 23‐year‐olds, body‐mass index (BMI) was measured at multiple time‐points from enrollment. BMI trajectories were interpolated with cubic polynomials. Fasting glucose, insulin and adiponectin were measured at 23 years. Homeostatic model assessment‐insulin resistance (HOMA‐IR), HOMA‐S, HOMA‐β, HOMA‐adiponectin (AD) and disposition index (DI) were estimated. IR and non‐alcoholic fatty liver (NAFL) were diagnosed. According to the BMI trajectory, five groups were defined: participants who were never obese (NOB); participants with obesity starting in adolescence and remained obese into adulthood (recent‐onset obesity, ROB); participants who were obese in early childhood but transitioned to non‐obesity as preadolescents (former obesity, FOB); participants who were obese in early childhood and remained obese into adulthood (persistent obesity, POB); participants with obesity starting in preadolescence and transitioned to non‐obesity as adolescents (transient obesity; TOB). Results Obesity was present in 47% of participants during at least one time‐point. ROBs and POBs had higher insulin, HOMA‐IR and HOMA‐β, lower HOMA‐S and DI, and higher prevalence of IR and NAFL at 23 years than NOBs, TOBs and FOBs. No differences were found in the β‐cell functionality of NOBs, TOBs and FOBs. Conclusions Persistent and recent obesity are both related to IR, NAFL and a decline of β‐cell function in emerging adulthood. Defeating obesity in childhood or adolescence allows reaching emerging adulthood with β‐cell functioning similar to that of subjects who were NOB.

An inexpensive and simple method to determine non-alcoholic fatty liver disease (NAFLD) is the abdominal ultrasound, but there are still doubts about its accuracy. We assessed the precision of a semi-quantitative ultrasound method to determine liver fat infiltration, using magnetic resonance spectroscopy (MRS) as the reference. The study was conducted in youths from an ongoing cohort study. Clinical validation was performed, using receiver operating characteristic analysis, in n = 60 participants (22.6y; 50% males). Abdominal ultrasound was carried out with liver brightness (score 0–3), diaphragm attenuation (0–2) and liver vessel blurring (0–1) scored by two observers. Liver fat was estimated using MRS. Then, analytical validation was conducted in the remaining participants (n = 555; 22.7y; 51% males) using effects size estimates. An ultrasound score ≥4.0 had the highest sensitivity (78%) and specificity (85%) for NAFLD diagnosis. An area under the curve of 86% denotes a good diagnostic performance of the test, whereas a Kappa of 0.63 suggests substantial agreement of ultrasound vs. MRS. The analytical validation showed that participants having NAFLD according to ultrasound had an unhealthier cardiometabolic profile than participants without the condition. Abdominal ultrasound, combined with a semi-quantitative score system, is a reliable method to determine liver fat infiltration in young adults and should be encouraged whenever MRS is unavailable.

Background Recently, hoarseness affecting the supraglottic structure has been reported in Kawasaki disease (KD). The objective of this study was to characterize the frequency of hoarseness in acute KD patients in Latin America. Methods We used prospective data from the multinational Red de Enfermedad de Kawasaki en America Latina (REKAMLATINA) network. A total of 865 patients from 20 countries were enrolled during the 3 year study period. Data on hoarseness were available in 858 (99.2%) patients. The clinical and laboratory characteristics between hoarse and non‐hoarse KD were compared. Results Hoarseness was documented in 100 (11.6%) patients. Hoarse patients were younger than those with KD without hoarseness (median age 18 vs 26 months; P = 0.002) and presented with lower hemoglobin (10.7 g/dL vs 11.3 g/dL; P = 0.040) and hematocrit levels (32% vs 33%, P = 0.048). Conclusions Hoarseness was found to be prevalent as a presenting sign of acute KD in younger children. Anemia may indicate the presence of active inflammation.
