Genomic and pharmacogenetic studies of childhood acute lymphoblastic leukemia

摘要：

With the cure rate of childhood acute lymphoblastic leukemia (ALL) approaching 90%, further improvement in the treatment outcome and quality of life of patients will require better understanding of the mechanisms of drug resistance, identifying new leukemic cell genetic lesions that are amendable to available target therapy, and optimizing treatment based on host pharmacodynamics and pharmacogenomics. Deeper characterization of leukemic cell genetic abnormalities has discovered new subtypes of leukemia such as early T-cell precursor ALL and Philadelphia chromosome-like ALL, and identified many genomic alterations that have diagnostic, prognostic, or therapeutic implications. In this regard, several novel fusion transcripts are responsive to ABL tyrosine kinase inhibitors and potentially to JAK inhibitors. Genome-wide analyses have also unraveled the role of inherited cancer predisposing genes and small nucleotide polymorphisms of several genes in the development of childhood ALL. These advances promise to lead to more sophisticated personalized treatment strategies in the near future.

Analyzing the distinguishing factors that affect childhood obesity in South Korea

摘要：

Understanding obesity in children is crucial because it can lead to adulthood obesity and result in fatal chronic diseases. Distinctive factors associated with obesity in adults have been described, but distinctive factors related to children remain unclear. We analyzed the correlation between the percentage of body mass index and lifestyle habits by conducting surveys on physical, nutritional, and psychological factors, and we used annual physical examination data to compare different traits among elementary school students (n = 197) and middle school students (n = 461). Our study revealed that the computing hours in elementary school students with overweight and obesity were significantly correlated with the percentage of body mass index (r = 0.29 on school days and r = 0.35 on days off, all P<0.05). No statistically significant difference was found (all P>0.05) in the computing hours of middle school students with overweight and obesity. Childhood obesity can cause depression and reduce children’s quality of life because of their distorted body perception. In conclusion, physical factors directly affecting childhood obesity and psychological and environmental factors surrounding a child should be considered.

Early T-cell precursor leukemia: a subtype of high risk childhood acute lymphoblastic leukemia

摘要：

Acute lymphoblastic leukemia includes T-cell acute lymphoblastic leukemia (T-ALL) and B-cell acute lymphoblastic leukemia (B-ALL). In children, T-ALL usually has a worse prognosis than B-ALL, although childhood T-ALL prognoses have improved remarkably. The varying outcomes among T-ALL cases suggest that an unrecognized biological heterogeneity may contribute to chemo-resistance. Deep exploration of T-lymphocyte development in recent years has found a subgroup of patients with a phenotype that resembles early T-cell precursor, which confers a much poorer prognosis than any other form of T-ALL. This novel subtype of T-ALL was called early T-cell precursor acute lymphoblastic leukemia (ETP-ALL). Flow cytometry data from T-ALL patients enrolled in Shanghai Children’s Medical Center between July 2002 and October 2010 were assessed according to Dr. Campana’s protocol. Among total 89 T-ALL cases, 74 cases had enough immunophenotype data available to differentiate between ETP (CD1a-, CD8-, CD5dim, at least one marker of stem cell or myeloid lineage) and non-ETP. From these 74 subjects, 12 ETP-ALL cases (16.2%) were identified. The event-free survival (EFS) rate at 66.8 months was 11.1%±10.1% for ETP-ALL and 57.6%±5.6% for non-ETP-ALL (P=0.003). The overall survival rates were 13.3%±11.0% for ETP-ALL and 64.7%±6.3% for non-ETP-ALL (P=0.002). Our findings demonstrate that early T-cell precursor leukemia is a very high-risk subtype of acute lymphoblastic leukemia with poor prognosis.

Prevalence of asthma symptoms in Golestan schoolchildren aged 6–7 and 13–14 years in Northeast Iran

摘要：

Asthma is the most common chronic disease among children, and its incidences are often imminent among elementary schoolchildren. This study aimed to examine the prevalence of asthma symptoms in Golestan schoolchildren aged 6–7 and 13–14 years in Northeast Iran. The prevalence rate was compared according to age group (aged 6–7 years vs. aged 13–14 years) and gender (male vs. female). In this cross-sectional study, 1706 Iranian schoolchildren aged 6–7 and 13–14 years in Golestan Province were enrolled. Participants completed questionnaires between February and July 2014. Asthma symptoms were assessed using the questionnaire of the International Study of Asthma and Allergies in Childhood protocol in Persian. The logistic regression model was used to estimate the odds ratios (ORs) and 95% confidence intervals (CIs) of the asthma symptoms for each of the gender and age groups. The prevalence rates of “current asthma” symptoms and “asthma ever” in all the children were estimated as 9.5% and 7.5%, respectively. The prevalence of asthma (“asthma ever” and “wheezing in the past 12 months”) in junior high schoolchildren (aged 13–14 years) is higher than that in elementary schoolchildren (aged 6–7 years) (P <0.05). The prevalence of the severity of wheezing in girls is lower than that in boys (OR= 1.7, 95%CI= 1.06–2.96, P = 0.02). Asthma is still a major public health problem. This study shows that the prevalence of the asthma symptoms in boys is lower than that in girls in both age groups, and the severity of asthma in girls is higher than that in boys aged 13–14 years.

摘要： China has been undertaking a profound reform on health care. Although more than 1.16 billion people have been covered by rural and urban medical insurance to date, the level of reimbursement from insurance is very limited, especially for critical diseases such as leukemia. This places heavy economic burdens on patients. Under these circumstances, systems innovation is imperative for the efficient utilization of limited funding. In this respect, certain valuable experience from other countries may prove helpful. The prospective payment system of Diagnosis-related Groups (DRGs), Clinical Paths, and the Comparative Effectiveness Analysis adopted by the National Institute of Health and Clinical Excellence (NICE, UK), can be fine tools to reduce medical costs and improve quality of services. Treatments of acute promyelocytic leukemia at Rui-Jin Hospital, and childhood acute lymphoblastic leukemia at Shanghai Children’s Medical Center, can be taken as suitable models to illustrate the crucial role of Clinical Paths in guaranteeing clinical and cost effectiveness of medical services for critical diseases, and to satisfactorily justify the feasibility of DRGs in China.
