Healthy lifestyle education programs are recommended for obesity prevention and treatment. However, there is no previous information on the effects of these programs on the reduction of hepatic fat percentage. The aims were (i) to examine the effectiveness of a 22-week family-based lifestyle education program on dietary habits, and (ii) to explore the associations of changes in dietary intake with percent hepatic fat reduction and adiposity in children with overweight/obesity. A total of 81 children with overweight/obesity (aged 10.6 ± 1.1 years, 53.1% girls) and their parents attended a 22-week family based healthy lifestyle and psychoeducational program accompanied with (intensive group) or without (control) an exercise program. Hepatic fat (magnetic resonance imaging), adiposity (dual energy X-ray absorptiometry) and dietary habits (two non-consecutive 24 h-recalls) were assessed before and after the intervention. Energy (p < 0.01) fat (p < 0.01) and added sugar (p < 0.03) intake were significantly reduced in both groups at the end of the program, while, in addition, carbohydrates intake (p < 0.04) was reduced exclusively in the control group, and simple sugar (p < 0.05) and cholesterol (p < 0.03) intake was reduced in the exercise group. Fruit (p < 0.03) and low-fat/skimmed dairy consumption (p < 0.02), the adherence to the Mediterranean Diet Quality Index for children and teenagers (KIDMED, p < 0.01) and breakfast quality index (p < 0.03) were significantly higher in both control and intervention groups after the intervention. Moreover, participants in the exercise group increased the adherence to the Dietary Approaches to Stop Hypertension (DASH) diet (p < 0.001), whereas the ratio of evening-morning energy intake was significantly lower exclusively in the control group after the program (p < 0.02). Changes in energy intake were significantly associated with changes in fat mass index (FMI) in the exercise group, whereas changes in sugar-sweetened beverages (SSB) consumption was associated with percent hepatic fat reduction (p < 0.05) in the control group. A 22-week family-based healthy lifestyle program seems to be effective on improving diet quality and health in children with overweight/obesity and these should focus on SSB avoidance and physical activity.

Silver–Russell syndrome (SRS) is a rare growth-related genetic disorder that is mainly associated with prenatal and postnatal growth retardation. Molecular causes are not clear in all cases, the most common ones being loss of methylation on chromosome 11p15 (≈50%) and maternal uniparental disomy for chromosome 7 (upd(7)mat) (≈10%). However, pathogenic variants in genes such as CDKN1C, HMGA2, IGF2, or PLAG1 have also been described. Previously, two families and one sporadic case have been reported with PLAG1 alterations. Here, we present a case of a female with clinical suspicion of SRS (i.e., intrauterine and postnatal growth retardation, triangular face, psychomotor delay, speech delay, feeding difficulties). No alterations in methylation or copy number were detected at chromosomes 11p15 and 7 using methylation-specific multiplex ligation-dependent probe amplification (MS-MLPA). The custom panel study by next-generation sequencing (NGS) revealed a frameshift variant in the PLAG1 gene (NM_002655.3:c.551delA; p.(Lys184Serfs *45)). Familial studies confirmed that the variant was inherited from the mother and it was also present in other family members. New evidence of pathogenic alterations in the HMGA2-PLAG1-IGF2 pathway suggest the importance of studying and taking into account these genes as alternative molecular causes of Silver–Russell syndrome.

Health related quality of life (HRQoL) is a relevant result when assessing the course of different pathologies and the efficacy of their treatments. HRQoL has been studied previously on adults born small for gestational age (SGA), both in the general population and in patients who had received recombinant human growth hormone (rhGH) treatment, with disparate results. Our study included 50 adults who had received rhGH treatment for the SGA indication in 4 Spanish hospitals. Data have been gathered retrospectively from their clinical records, current weight and height were measured, and patients have been asked to fill out SF-36 and QoLAGHDA quality of life forms, and the Graffar test to evaluate their socio-economical status. Patient’s adult height was – 1.2 ± 0.9 SD, lower than their target height of 1 ± 0.8 SD, but gaining 1.7 ± 1 SD from the beginning of the treatment. SF-36 test results showed lower scoring on Mental Health domains than on those related to Physical Health. No correlation was found between HRQoL results and final height, rhGH treatment duration or puberty. Correlation was indeed found between QoLAGHDA and several domains of SF-36, but QoLAGHDA detected fewer patients with low HRQoL than SF-36. Thus, it is concluded that SGA patient’s follow-up should include a HRQoL, neuro-cognitive and psychiatric assessment in their transition to adult age. Adult SGA patients without catch up growth have impaired HRQoL, especially in mental health domains.
