Sugar has become embedded in modern food and beverages. This has led to overconsumption of sugar in children, adolescents, and adults, with more than 60 countries consuming more than four times (>100 g/person/day) the WHO recommendations (25 g/person/day). Recent evidence suggests that obesity and impulsivity from poor dietary habits leads to further overconsumption of processed food and beverages. The long-term effects on cognitive processes and hyperactivity from sugar overconsumption, beginning at adolescence are not known. Using a well-validated mouse model of sugar consumption, we found that long-term sugar consumption, at a level that significantly augments weight gain, elicits an abnormal hyperlocomotor response to novelty and alters both episodic and spatial memory. Our results are similar to those reported in attention deficit and hyperactivity disorders. The deficits in hippocampal-dependent learning and memory were accompanied by altered hippocampal neurogenesis, with an overall decrease in the proliferation and differentiation of newborn neurons within the dentate gyrus. This suggests that long-term overconsumption of sugar, as that which occurs in the Western Diet might contribute to an increased risk of developing persistent hyperactivity and neurocognitive deficits in adulthood.

AbstractThe efficacy of combining radiation therapy with immune checkpoint inhibitor blockade to treat brain tumors is currently the subject of multiple investigations and holds significant therapeutic promise. However, the long-term effects of this combination therapy on the normal brain tissue are unknown. Here, we examined mice that were intracranially implanted with murine glioma cell line and became long-term survivors after treatment with a combination of 10 Gy cranial irradiation (RT) and anti-PD-1 checkpoint blockade (aPD-1). Post-mortem analysis of the cerebral hemisphere contralateral to tumor implantation showed complete abolishment of hippocampal neurogenesis, but neural stem cells were well preserved in subventricular zone. In addition, we observed a drastic reduction in the number of mature oligodendrocytes in the subcortical white matter. Importantly, this observation was evident specifically in the combined (RT + aPD-1) treatment group but not in the single treatment arm of either RT alone or aPD-1 alone. Elimination of microglia with a small molecule inhibitor of colony stimulated factor-1 receptor (PLX5622) prevented the loss of mature oligodendrocytes. These results identify for the first time a unique pattern of normal tissue changes in the brain secondary to combination treatment with radiotherapy and immunotherapy. The results also suggest a role for microglia as key mediators of the adverse treatment effect.

Chromosome 17 duplication is correlated with an increased risk of developmental delay, birth defects, and intellectual disability. Here, we reported a female patient with trisomy 17 on the whole short arm with bilateral complete cleft lip and palate (BCLP). This study will review the surgical strategies to reconstruct the protruding premaxillary segment, cleft lip, and palate in trisomy 17p patient. The patient had heterozygous pathogenic duplication of chromosomal region chr17:526-18777088 on almost the entire short arm of chromosome 17. Beside the commonly found features of trisomy 17p, the patient also presented with BCLP with a prominent premaxillary portion. Premaxillary setback surgery was first performed concomitantly with cheiloplasty. The ostectomy was performed posterior to the vomero-premaxillary suture (VPS). The premaxilla was firmly adhered to the lateral segment and the viability of philtral flap was not compromised. Two-flap palatoplasty with modified intravelar veloplasty (IVV) was performed 4 months after. Successful positioning of the premaxilla segment, satisfactory lip aesthetics, and vital palatal flap was obtained from premaxillary setback, primary cheiloplasty, and subsequent palatoplasty in our trisomy 17p patient presenting with BLCP. Postoperative premaxillary stability and patency of the philtral and palatal flap were achieved. Longer follow-up is needed to evaluate the long-term effects of our surgical techniques on inhibition of midfacial growth. However, the benefits that the patient received from the surgery in improving feeding capacity and facial appearance early in life outweigh the cost of possible maxillary retrusion.

This is the first reported study of birth outcomes of a group of women whose own birth weights and gestational ages had been previously recorded. Births occurring from 1972 to 1983 among 1154 Swedish women, born from 1955 to 1965, were studied. Women who were themselves small for gestational age (SGA) at birth were at increased risk of giving birth to a SGA infant (odds ratio = 2.21, 95% confidence interval = 1.41, 3.48). Women who had been SGA had an even greater increase in risk of giving birth to a preterm infant (odds ratio = 2.96, 95% confidence interval = 1.47, 5.94). Women who were preterm at birth were not at increased risk of giving birth to either preterm (odds ratio = 0.65, 95% confidence interval = 0.15, 2.74) or SGA (odds ratio 1.21, 95% confidence interval = 0.62, 2.38) infants. It is concluded that the long-term effects of intrauterine growth retardation may extend to the next generation; women who had been SGA should be considered at increased risk to give birth to both growth-retarded and preterm infants.

Ample evidence from epidemiological studies has linked maternal obesity with metabolic disorders such as obesity, cardiovascular disease, and diabetes in the next generation. Recently, it was also shown that maternal obesity has long-term effects on the progeny’s central nervous system. However, very little is known regarding how maternal overnutrition may affect, in particular, the cognitive abilities of the offspring. We reported that first-generation offspring exposed to a maternal high-fat diet (MHFD) displayed age-dependent cognitive deficits. These deficits were associated with attenuations of amino acid levels in the medial prefrontal cortex and the hippocampus regions of MHFD offspring. Here, we tested the hypothesis that MHFD in mice may induce long-term cognitive impairments and neurochemical dysfunctions in the second and third generations. We found that MHFD led to cognitive disabilities and an altered response to a noncompetitive receptor antagonist of the N-Methyl-D-aspartic acid (NMDA) receptor in adult MHFD offspring in both second and third generations in a sex-specific manner. Our results suggest that maternal overnutrition leads to an increased risk of developing obesity in subsequent generations as well as to cognitive impairments, affecting learning and memory processes in adulthood. Furthermore, MHFD exposure may facilitate pathological brain aging which is not a consequence of obesity. Our findings shed light on the long-term effects of maternal overnutrition on the development of the central nervous system and the underlying mechanisms which these traits relate to disease predisposition.

Data from the National Institute on Drug Abuse (NIDA) and the Centers for Disease Control and Prevention (CDC) reveal high numbers of adolescent substance use in the United States. Substance use among adolescents can lead to increased risk of transmission of sexually transmitted infections, vehicular fatalities, juvenile delinquency, and other problems associated with physical and mental health. Adolescents are particularly susceptible to involvement in substance use due to the underdeveloped state of the adolescent brain, which can lead to reduced decision-making ability and increased long-term effects of drugs and alcohol. Understanding the causes of adolescent substance use is vital for successful prevention and intervention programs.

Overweight and obesity cause pathophysiological changes in renal function and increase the risk for chronic kidney disease in otherwise healthy subjects. This should not be a surprise as the risk factors for metabolic syndrome largely overlap with those for chronic kidney disease. Intentional weight loss has beneficial effects on risk factors, but long term effects are less clear. Bariatric surgery does seem to achieve rapid benefits on blood pressure and proteinuria as well as on other aspects of metabolic syndrome, but its long term implications for kidney function are less clear cut as there may be an increased risk of nephrolithiasis, and possibly AKI and other complications.Obesity in haemodialysis patients is one of those paradoxical examples of reverse epidemiology where a factor associated with negative outcomes in the general population is associated with better outcomes in dialysis patients. The same is true for high blood cholesterol values. Interpretation is complicated by complex competing outcomes and confounders.

SummaryPerioperative antithrombotic clinical regimens have reduced the incidence of postoperative deep venous thrombosis (DVT). Long-term effects of asymptomatic postoperative DVT have been studied in a number of clinical trials and the present review describes the clinical significance of asymptomatic postoperative DVT regarding the possible development of postthrombotic syndrome (PTS).We performed a systematic review of reference databases focusing upon studies including patients suspected of having postoperative DVT and reporting subsequent cases of PTS at the end of a well-defined follow-up period. The included studies were stratified according to type of screening method and applied statistics. Over-all evaluation included metaanalyses based upon the Cochrane software package. The overall relative risk of developing PTS was 1.58 (95% confidence intervals: 1.24 – 2.02) in patients suffering from asymptomatic DVT as compared to patients without DVT ( p < 0.0005).In conclusion, asymptomatic postoperative DVT is associated with an increased risk of late development of PTS. The finding emphasizes that postoperative DVT, diagnosed by means of well-defined objective measures, remains the correct scientific endpoint in trials evaluating the efficacy of preoperative antithrombotic treatment regimens.

e21500 Background: The 5-year survival rate for pediatric acute lymphoblastic leukemia (ALL) is greater than 90%. A common late effect of pediatric ALL is neurocognitive deficits, such as lower IQ. In recent years, the use of sedation during lumbar punctures (LPs) for treatment of pediatric ALL is becoming increasingly widespread. These patients are exposed to repeated doses of sedatives. Among the most common Children’s Oncology Group (COG) ALL protocols, approximately 30 LPs are performed over a period of 2-3 years. Studies in animals (both rodents and primates) have revealed that common sedation drugs cause harm to the developing brain and can negatively affect behavior, learning, and memory. Gaps in knowledge exist regarding their use in children, particularly with repeated exposures. For children with ALL, little is known about sedation practices such as how commonly sedation is used; what medications are most common; and who administers the medications. The purpose of this study is to summarize sedation practices at COG institutions for LPs related to treatment of pediatric ALL. Methods: All Responsible Investigators (RIs) of the Cancer Control Committee (a subcommittee of COG) were invited to complete an internet-based survey about sedation practices for ALL patients at their institution. Results: Surveys were sent out to 103 RIs with a 62.1% response rate ( N = 64). A combined 2018 new patients with ALL were seen each year ( M = 31.5, range = 3-110); of these patients, 95.7% received sedation for LPs. While there was considerable variability across institutions in medications used (general anesthesia, Propofol with opioid and/or Versed, Versed and opioid, other), the most common was Propofol alone ( n = 36, 56.3%). Anesthesiologists administered sedation at the majority of institutions ( n = 36, 56.3%) while trained sedationists, oncologists, and nurses administered sedation at other institutions. Conclusions: A substantial number of pediatric patients with ALL receive sedation for LPs. However, there is much variation in the types of medications administered and who is administering these medications. Better understanding of sedation practices in children with ALL may inform future research to investigate which methods of sedation are safest, with a particular emphasis on its long-term effects.

The aim of the present study was to assess the long-term effects of a high-energy-dense diet, supplemented with Lactobacillus plantarum (Lp) or Escherichiacoli (Ec), on weight gain, fattening and the gut microbiota in rats. Since the mother's dietary habits can influence offspring physiology, dietary regimens started with the dams at pregnancy and throughout lactation and continued with the offspring for 6 months. The weight gain of group Lp was lower than that of groups C (control) and Ec (P = 0·086). More retroperitoneal adipose tissue (P = 0·030) and higher plasma leptin (P = 0·035) were observed in group Ec compared with group Lp. The viable count of Enterobacteriaceae was higher in group Ec than in group Lp (P = 0·019), and when all animals were compared, Enterobacteriaceae correlated positively with body weight (r 0·428, P = 0·029). Bacterial diversity was lower in group Ec than in groups C (P ≤ 0·05) and Lp (P ≤ 0·05). Firmicutes, Bacteroidetes and Verrucomicrobia dominated in all groups, but Bacteroidetes were more prevalent in group C than in groups Lp (P = 0·036) and Ec (P = 0·056). The same five bacterial families dominated the microbiota of groups Ec and C, and four of these were also present in group Lp. The other five families dominating in group Lp were not found in any of the other groups. Multivariate data analysis pointed in the same directions as the univariate statistics. The present results suggest that supplementation of L. plantarum or E. coli can have long-term effects on the composition of the intestinal microbiota, as well as on weight gain and fattening.

Background: Physical trauma, specifically concussions sustained during adolescence, has been hypothesized to be a risk factor for multiple sclerosis (MS). Objective: To examine the association between adolescent concussions and future MS diagnosis. Methods: This retrospective study using linked administrative databases from Ontario, Canada, identified 97,965 adolescents (age 11–18 years) who sustained ⩾1 concussion and presented to an emergency department between 1992 and 2011. Cases were matched 1:3 with individuals who had not sustained a concussion based on age, sex, address, and index date. The primary outcome was MS diagnosis, using a validated MS diagnosis definition: ⩾1 hospitalization or ⩾5 physician billings within 2 years. Results: A concussion during adolescence was associated with a significantly increased risk of MS (hazard ratio (HR) = 1.29, p = 0.03). Sex-specific analysis revealed that only males who sustained a concussion in adolescence had a raised risk of MS (HR = 1.41, p = 0.04). Conclusion: This study supports an association between concussions in adolescence and future MS diagnoses, highlighting the potentially serious long-term effects of concussions.
