Objective Several evidences demonstrate that pre-sleep habits may negatively impact adolescent sleep, yet few data exist on Italian population. This study aimed to investigate the relationship between pre-sleep habits, use of technology/activity and sleep in Italian adolescents. Methods Self-report questionnaires including Italian version of School Sleep Habits Survey and use of technology/activity (eg smartphone, PC) at bedtime were administered to 972 adolescents (13–19 years) from Lombardia. We stratified the sample in five groups according to the age: Group I (13–14 years), Group II (15 years), Group III (16 years), Group IV (17 years), Group V (18–19 years). Results Our descriptive analysis reveals a different sleep profile across age-groups: Group III showed highest percentage of bad sleep (26.7%) and frequent nocturnal awakenings (24.1%), Group V had the highest percentage of insufficient sleep (40,4%) and difficulty falling asleep (42.7%) and Group IV presented an elevated difficulty in waking up in the morning (70.1%). A significant negative correlation was found in total group between use of smartphone, internet and studying/doing homework and total sleep time. The use of smartphone, internet videogames, listening to music and studying/doing homework was positively associated with delayed bedtime. Conclusions This study confirms the great impact of pre-sleep habits, and in particular the use of technology on adolescent sleep. Our results demonstrate that sleep is strongly altered among Italian adolescents using electronic devices in evening. The type of technology may be related to specific sleep profile, emphasizing the importance of stratification analyses to identify associated factors to sleep problems.

ANTECEDENTES: La lesión cerebral traumática (LCT) será la tercera causa de muerte en todo el mundo, según la OMS. Dos encuestas europeas sugirieron que el cumplimiento de las directrices sobre traumatismos craneoencefálicos es deficiente. Ningún estudio ha comparado el cumplimiento entre países de ingresos bajos (LMIC) y países de ingresos altos (UHIC). Por lo tanto, este estudio tuvo como objetivo investigar las diferencias en el manejo de pacientes con TBI grave, comparando ingresos bajos y altos, y la adherencia a las pautas de BTF. MÉTODOS: se difundió una encuesta basada en la web a través de la fundación global Neuro, diferentes sociedades neuroquirúrgicas y las redes sociales. RESULTADOS: participaron un total de 803 neurocirujanos: 70,4 de UHIC y 29,6% de LMIC. El 73 % y el 65 % de los que respondieron en LMIC y UHIC, respectivamente (P = 0,016), administraron hipertónico como medida temprana. El 66 % y el 58 % de los neurocirujanos de los LMIC y los UHIC recomendaron una monitorización invasiva de la presión intracraneal, respectivamente (p

2-3 antigens mismatched BMT were performed on 32 children without a matched sibling donor. In the light of previous in vitro studies, which suggested a role of Vincristine and Methilprednisolone ex vivo treatment in modulating alloreactivity of T cells, bone marrow was treated with such a pharmacological cocktail before being infused. Acute GVHD 2 degrees to 4 degrees degree occurred in 46% of cases, chronic GVHD in 28%, graft failure in 13%. There was no significant difference between 2- and 3-antigens mismatched BMT as far as GVHD and graft failure are concerned.

Background & aims: Variations in gut microbiota might impact metabolism leading to body weight excess. We assessed the impact of a probiotic supplementation in pediatric obesity on weight, metabolic alterations, selected gut microbial groups, and functionality. Methods: Cross-over, double-blind, randomized control trial (BIFI-OBESE trial; NCT03261466). 101 youths (6–18 years, Tanner stage ≥2) with obesity and insulin-resistance on diet were randomized to 2 × 109 CFU/AFU/day of Bifidobacterium breve BR03 (DSM 16604) and B. breve B632 (DSM 24706) (51) or placebo (50) for 8 weeks with a 4-weeks wash-out period. Results: All subjects (M/F 54/47) completed the first 8 weeks, and 82 (M/F 43/39) the last part without adverse events. Mixed-effects models revealed a carry-over effect on many variables in the entire study, narrowing the analysis to the first 8 weeks before the wash-out periods. All subjects improved metabolic parameters, and decreased weight and Escherichia coli counts. Probiotics improved insulin sensitivity at fasting (QUICKI, 0.013 CI95%0.0–0.03) and during OGTT (ISI, 0.654 CI95%-0.11–1.41). Cytokines, GLP1, and target microbial counts did not vary. Of 25 SCFAs, acetic acid and acetic acid pentyl-ester relative abundance remained stable in the probiotics, while increased in the placebo (p < 0.02). A signature of five butanoic esters identified three clusters, one of them had better glucose responses during probiotics. Conclusion: An 8 weeks treatment with B. breve BR03 and B632 had beneficial effects on insulin sensitivity in youths with obesity. Microbiota functionality could influence metabolic answers to probiotics. Long-term studies to confirm and enrich our findings are justified. Tailored probiotic treatments could be an additional strategy for obesity. Trial registration: NCT03261466.

Five young patients with Niemann-Pick disease type B were treated with repeated implantations of amniotic epithelial cells, as a source of exogenous sphingomyelinase. This treatment abolished the recurrent infections, mainly of the respiratory tract, and led to other improvements of the general conditions of the patients. In particular, we noticed a disappearance of vomiting, a recovery from muscular hypotrophy, and significantly reduced pulmonary distress. In four subjects, who were in a prepuberal state, there was a puberal spurt with a concomitant burst of growth. In two cases, characterized by a greater than normal content of sphingomyelin in urinary sediments, a single implantation caused a sustained normalization of sphingomyelin and total phospholipids in the urine. Finally, sphingomyelinase activity of peripheral leukocytes, when assayed 0.5 to 4 months after some of the implantations, showed a rise to heterozygous values in 30-40% of the assays.

In a patient with a lysosomal storage disorder, not involving the CNS, repeated implantations of human amniotic sheets have proved to provide a successful approach to enzyme replacement therapy. Implantation of pure epithelial cells, separated from the other cell types of the amnion, might markedly improve the procedure, avoiding some risks of host-versus-graft rejection.
