Access to Support Services for Newcomer Youth Through the Process of School Integration: A Critical Narrative Literature Review.

While the numbers of newcomer youth continue to grow in Canada, few studies have sought to critically capture experiences of school integration and access to school-based psychosocial support services during their transition. Guided by a critical social justice lens, this research seeks to investigate issues of inequity due to the marginalization of newcomer youth in schools. The intent of this critical narrative review is to summarize, interpret, critique, and synthesize what is currently known about the ways newcomer youth access and experience school-based psychosocial support services (S-BPSS) throughout the process of school integration. This paper presents the critical narrative literature review process, a discussion of the themes that emerged from the review, and a discussion of the literature within the context of school integration. The following themes that underscore the experiences of newcomer youth accessing school-based psychosocial support services were identified: (a) underutilization/discrimination, (b) culture shift, (c) transition planning, and (d) lived experience. Important directions for future research, including the importance of studies that prioritize the perspectives of newcomer youth themselves and the implications of their lived experience for S-BPSS are provided.

Exploring perceptions of positive mental health in young adults with intellectual disabilities.

BACKGROUND: Despite having higher levels of mental health difficulties than the general population, limited research exists about how individuals with intellectual disabilities view mental health. Providing education about mental health literacy can contribute to maintaining positive mental health. Individuals who understand positive mental health are more likely to take steps to improve their mental health. AIMS: This study explores how young adults with intellectual disabilities conceptualise and define the concept of positive mental health. MATERIALS & METHODS: Eight participants were interviewed using phenomenographic methods. RESULTS: Using phenomenography as the approach, four categories of description emerged from the analysis and included defining positive mental health as related to physical health, lack of clarity about positive mental health, positive qualities (emotions and actions) and mental health components. DISCUSSION: This study highlights the need for further research, exploring how to provide support through psychoeducation to individuals with intellectual disabilities about mental health.

Psychometric Properties of the Spence Children's Anxiety Scale: Parent Report in Children with Autism Spectrum Disorder.

Although anxiety is frequently reported in children with autism spectrum disorder (ASD), existing anxiety scales are often psychometrically inappropriate for this population. This study examined the internal structure, reliability, convergent and discriminant validity of the Spence Children's Anxiety Scale-Parent Report (SCAS-P; Spence 1999) in 238 school-aged children with ASD. While confirmatory factor analysis did not support the original six-correlated-factor structure, structural support as well as acceptable internal consistency and convergent validity was found for Generalized Anxiety, Separation Anxiety, Panic, and Agoraphobia subscales. Use of the SCAS-P in its original form for assessment in children with ASD was not supported. However, four subscales showed viability, and may benefit re-analyses of existing SCAS-P data and future scale adaptations for research and clinical purposes.

A phase I study of intermediate dose cytarabine in combination with lenalidomide in relapsed/refractory acute myeloid leukemia.

Relapsed/refractory (r/r) Acute Myeloid Leukemia (AML) remains a therapeutic challenge. Cytarabine arabinoside (AraC) forms the backbone of most regimens, with complete responses (CR) ranging from 17 to 20%. Lenalidomide (Len) is approved by the FDA for multiple myeloma and myelodysplasia and has demonstrated activity in AML. We developed a phase I study to evaluate the safety and tolerability of Len in combination with intermediate dose AraC (1.5 g/m(2)/day given on days 1-5) in adults with r/r AML. The maximally tolerated dose for this combination was 10mg daily on days 6-26 of a 28 day cycle. Dose de-escalation from 25mg was required due to rash, liver function abnormalities, and hypokalemia. Of 32 evaluable patients, five achieved CR (16%), 5CRi (16%) and 3 had hematological improvements for an overall response rate of 41% (13/32). Median overall survival (95% confidence interval) for patients treated on study was 5.8 (2.5-10.6) months and disease free survival was 3.4 (2.3-6.2) months. This single institute phase I trial of Len and intermediate dose AraC was associated with marked skin and other toxicities. At the dose and schedule tested, this combination did not appear to result in improved CR over single agent AraC for r/r AML.

Induction of cancer testis antigen expression in circulating acute myeloid leukemia blasts following hypomethylating agent monotherapy.

Cancer testis antigens (CTAs) are promising cancer associated antigens in solid tumors, but in acute myeloid leukemia, dense promoter methylation silences their expression. Leukemia cell lines exposed to HMAs induce expression of CTAs. We hypothesized that AML patients treated with standard of care decitabine (20mg/m2 per day for 10 days) would demonstrate induced expression of CTAs. Peripheral blood blasts serially isolated from AML patients treated with decitabine were evaluated for CTA gene expression and demethylation. Induction of NY-ESO-1 and MAGEA3/A6, were observed following decitabine. Re-expression of NY-ESO-1 and MAGEA3/A6 was associated with both promoter specific and global (LINE-1) hypomethylation. NY-ESO-1 and MAGEA3/A6 mRNA levels were increased irrespective of clinical response, suggesting that these antigens might be applicable even in patients who are not responsive to HMA therapy. Circulating blasts harvested after decitabine demonstrate induced NY-ESO-1 expression sufficient to activate NY-ESO-1 specific CD8+ T-cells. Induction of CTA expression sufficient for recognition by T-cells occurs in AML patients receiving decitabine. Vaccination against NY-ESO-1 in this patient population is feasible.

Decitabine and Sorafenib Therapy in FLT-3 ITD-Mutant Acute Myeloid Leukemia.

BACKGROUND: Acute myeloid leukemia (AML) characterized by Feline McDonough Sarcoma-like tyrosine kinase-3 (FLT-3) internal tandem duplication (ITD) mutations have poor outcomes. Treatment options are limited, because these mutations confer resistance to conventional chemotherapy. FLT-3 inhibitors such as sorafenib have been studied as a single agent and in combination with conventional chemotherapy or azacytidine with fair responses. PATIENTS AND METHODS: Here we describe our preclinical and clinical experience with the combination of the DNA hypomethylating agent, decitabine and sorafenib for the treatment of FLT-3 ITD-mutant AML. RESULTS: In vitro treatment of the human FLT-3 ITD-mutant AML cell line, MV4-11, with both drugs significantly improved growth inhibition over single-agent therapy and resulted in synergistic antitumor effects (combination index < 1). A case series of 6 patients treated with off protocol combination of decitabine and sorafenib demonstrated overall responses in 5 patients (83%) with a median survival of 155 days. Four of the 5 patients (80%) with relapsed/refractory AML achieved complete responses with incomplete count recovery. The combination was also well tolerated. CONCLUSION: Further investigation is warranted to confirm these responses.

Comparison of epigenetic versus standard induction chemotherapy for newly diagnosed acute myeloid leukemia patients ≥60 years old.

Older patients with acute myeloid leukemia (AML) have poor outcomes with standard induction chemotherapy. We retrospectively reviewed our institute's experience with epigenetic (Epi) versus cytarabine- and anthracycline-based intensive chemotherapy (IC) as induction in newly diagnosed AML patients aged 60 years and older. One hundred sixty-seven patients (n = 84, IC; n = 83, Epi) were assessed; 69 patients received decitabine and 14 azacitidine. Baseline characteristics between the IC and Epi patient cohorts were not statistically different except for age, initial white blood cell count, and comorbidity index. Overall response rate (ORR, 50% vs. 28%, respectively, P < 0.01) and complete response rate (CRR, 43% vs. 20%, respectively, P < 0.01) were superior following IC vs. Epi. Although univariate analysis demonstrated longer overall survival after IC (10.7 vs. 9.1 months, P = 0.012), multivariate analysis showed no independent impact of induction treatment. Treatment-related mortality was not statistically different in the two groups. Outcomes of patients with secondary, poor cytogenetic risk, FLT-3 mutated AML, or relapsed/refractory disease after IC or Epi were not significantly different. Outcomes of patients receiving IC versus a 10-day decitabine regimen (n = 63) also were not significantly different. Our results suggest that IC and Epi therapy are clinically equivalent approaches for upfront treatment of older patients with AML and that other factors (feasibility, toxicity, cost, etc.) should drive treatment decisions. Prospective randomized trials to determine the optimal induction approach for specific patient subsets are needed.

Presence of isocitrate dehydrogenase mutations may predict clinical response to hypomethylating agents in patients with acute myeloid leukemia.

Mutations in IDH1 and IDH2 occur in 15-20% of AML cases, resulting in the production of 2-hydroxyglutarate, which promotes aberrant hypermethylation of DNA in leukemic cells. Although these mutations have been shown to have prognostic implications for patients with AML, optimal treatment strategies have yet to be defined. We retrospectively identified forty-two patients with AML treated with DNA methyltransferase inhibitors (DNMTIs) decitabine (n = 36) or azacitidine (n = 6) and performed analysis of stored samples for the presence of IDH1 and IDH2 mutations. Of the forty-two samples analyzed, seven (16.7%) had IDH mutations. Thirteen patients (31%) achieved remission [(complete remission (CR)/complete remission with incomplete count recovery (CRi)/partial response (PR)] after treatment with a DNMTI, five of seven (71.4%) with IDH mutations and eight of thirty-five (22.9%) without IDH mutations (P = 0.01). When adjusted for age at diagnosis, sex, bone marrow blast percentage and cytogenetic, the odds of achieving response after administration of a DNMTI among patients with an IDH mutation was 14.2 when compared to patients without an IDH mutation (95%CI: 1.3-150.4). IDH1 and IDH2 mutations may predict a favorable response to DNMTI in patients with AML.

Caregivers' management of schooling for their children with fetal alcohol spectrum disorder.

In this article we describe a grounded theory study of how caregivers of school-aged children with fetal alcohol spectrum disorder (FASD) managed their children's schooling. We completed 30 interviews with 17 caregivers residing in a western Canadian province, as well as document analysis and 25 hours of participant observation. We used constant comparative analysis to construct our substantive theory: intertwining to fit in. The core variable is an iterative cycle caregivers used to resolve their main concerns: preventing their children from failing academically and in social interactions and preventing themselves from being regarded as unacceptable parents. To intertwine to fit in, caregivers used two strategies: orchestrating schooling and keeping up appearances. They also regulated their relationships with their children. "Intertwining to fit in" contributes to the literature on attachment and parenting and extends explanations about caregivers' advocacy for their children with FASD. The theory has implications for school personnel and practitioners, as well as researchers.

Low 25(OH) vitamin D3 levels are associated with adverse outcome in newly diagnosed, intensively treated adult acute myeloid leukemia.

BACKGROUND: Several studies have suggested that low 25(OH) vitamin D3 levels may be prognostic in some malignancies, but no studies have evaluated their impact on treatment outcome in patients with acute myeloid leukemia (AML). METHODS: Vitamin D levels were evaluated in 97 consecutive, newly diagnosed, intensively treated patients with AML. MicroRNA expression profiles and single nucleotide polymorphisms (SNPs) in the 25(OH) vitamin D3 pathway genes were evaluated and correlated with 25(OH) vitamin D3 levels and treatment outcome. RESULTS: Thirty-four patients (35%) had normal 25(OH) vitamin D3 levels (32-100 ng/mL), 34 patients (35%) had insufficient levels (20-31.9 ng/mL), and 29 patients (30%) had deficient levels (<20 ng/mL). Insufficient/deficient 25(OH) vitamin D3 levels were associated with worse relapse-free survival (RFS) compared with normal vitamin D3 levels. In multivariate analyses, deficient 25(OH) vitamin D3 , smoking, European Leukemia Network genetic group, and white blood cell count retained their statistical significance for RFS. Several microRNAs and SNPs were associated with 25(OH) vitamin D3 levels, although none remained significant after multiple test corrections; one 25(OH) vitamin D3 receptor SNP, rs10783219, was associated with a lower complete remission rate (P = .0442) and with shorter RFS (P = .0058) and overall survival (P = .0011). CONCLUSIONS: It remains to be determined what role microRNA and SNP profiles play in contributing to low 25(OH) vitamin D3 level and/or outcome and whether supplementation will improve outcomes for patients with AML.

13-Valent pneumococcal conjugate vaccine in older children and adolescents either previously immunized with or naïve to 7-valent pneumococcal conjugate vaccine.

BACKGROUND: The 13-valent pneumococcal conjugate vaccine (PCV13) has been demonstrated to be immunogenic and safe for administration to infants and children aged <5 years. PCV13 recently was approved for children and adolescents aged up to 17 years as the vaccine may be of benefit to some in this older age group. METHODS: In this open-label study, healthy children aged ≥5 to <10 years (ie, the younger age group) previously vaccinated (≥1 dose) with 7-valent PCV (PCV7) and pneumococcal vaccine-naïve children aged ≥10 to <18 years (ie, the older age group) received 1 dose of PCV13. For the younger group, antipneumococcal immunoglobulin (Ig) G geometric mean concentrations 1 month postvaccination were compared with posttoddler dose (PCV13 or PCV7) levels from a historical control study. Opsonophagocytic activity geometric mean titers 1 month postvaccination for the older group were compared with the younger age group. Safety data were collected. RESULTS: Five hundred and ninety-eight children were enrolled, 299 in each age group. For PCV7 serotypes, IgG geometric mean concentrations in the younger group were 8.23-53.56 µg/mL, ≥2.5-fold greater than historical posttoddler dose values. For the 6 additional serotypes, IgG geometric mean concentrations in the younger group were 2.38-21.51 µg/mL, ≥1.2-fold greater than historical posttoddler dose values. Opsonophagocytic activity geometric mean titers were similar in the older and younger age groups, except for serotype 3 which was lower in the older group. Safety was comparable in both groups. CONCLUSIONS: PCV13 was immunogenic and safe when administered to older children and adolescents, regardless of prior PCV7 vaccination.

Phase II trial of clofarabine and daunorubicin as induction therapy for acute myeloid leukemia patients greater than or equal to 60 years of age.

We designed a phase II study evaluating the upfront combination of clofarabine and daunorubicin in acute myeloid leukemia (AML) patients≥60 years old. The median age of the 21 patients was 69 (range 60-85) years. Fourteen patients (67%) had unfavorable risk features. The principal toxicities were grade ≥3 infections and prolonged myelosuppression. Three (14%) deaths occurred from infectious complications. Six (28.6%) patients achieved complete remission including three (21.4%) of 14 patients with unfavorable AML. The median disease-free survival was 6.8 months and the median overall survival was 11.2 months.

Phase I/II trial of nanomolecular liposomal annamycin in adult patients with relapsed/refractory acute lymphoblastic leukemia.

BACKGROUND: Treatment options for relapsed/refractory ALL in adult patients remain challenging. Annamycin is a highly lipophilic form of the anthracycline doxorubicin with the ability to bypass multidrug resistance mechanisms of cellular drug resistance. PATIENTS AND METHODS: We performed a phase I/II multicenter, open-label, study to determine the maximally tolerated dose (MTD) of nanomolecular liposomal annamycin in adult patients with refractory ALL. RESULTS: Thirty-one patients were enrolled; the MTD was determined to be 150 mg/m(2)/d for 3 days. Other than tumor lysis syndrome, there were 3 grade 3 mucositis which comprised the MTD determination. There was also 1 case each of grade 3 diarrhea, typhlitis, and nausea. After determining the MTD, a 10-patient phase IIA trial was conducted. Eight of the patients completed 1 cycle of the 3 days of treatment at the MTD. Of these, 5 (62%) had an efficacy signal with complete clearing of circulating peripheral blasts. Three of these subjects also cleared bone marrow blasts with 1 subsequently proceeding onto successful stem cell transplantation. CONCLUSION: Single-agent nanomolecular liposomal annamycin appears to be well tolerated, and shows evidence of clinical activity as a single agent in refractory adult ALL.

Down-regulation of signal transducer and activator of transcription 3 improves human acute myeloid leukemia-derived dendritic cell function.

Signal transducer and activator of transcription (STAT) 3 inhibits dendritic cell (DC) differentiation and is constitutively activated in blasts of approximately half of AML patients. We investigated the correlation between STAT3 activity, DC maturation and the ability to stimulate T-cells in primary acute myeloid leukemia (AML)-derived DCs. STAT3 knock-down by shRNAmir increased the ability of AML-DCs to stimulate T-cells. Treatment of AML-DC with arsenic trioxide, but not AG490, JSI-124 or NSC-74859, led to a more mature phenotype and enhanced T-cell stimulation, while having minimal effect on normal DC. We conclude that AML-DCs have improved immunogenicity after reducing STAT3.

Myelodysplastic syndromes and autoimmune diseases--case series and review of literature.

Our objective was to recognize the association of autoimmune diseases (AD) in patients with myelodysplastic syndromes (MDS) and understand how this association could affect prognosis and management of both diseases. We describe our cohort of 10 patients and 34 patients reported in the English literature in addition to ten cohort studies. Interestingly, four cases showed improvement in AD after 5-azacitidine treatment. The mechanism(s) of the association between AD and MDS are discussed. Treatment could be targeted against AD, MDS or both, though based on recent reports, treating MDS with hypomethylating agents alone could improve the associated AD.

Smoking adversely affects survival in acute myeloid leukemia patients.

Smoking adversely affects hematopoietic stem cell transplantation outcome. We asked whether smoking affected outcome of newly diagnosed acute myeloid leukemia (AML) patients treated with chemotherapy. Data were collected on 280 AML patients treated with high-dose cytarabine and idarubicin-containing regimens at Roswell Park Cancer Institute who had smoking status data at diagnosis. Patients' gender, age, AML presentation (de novo vs. secondary), white blood cell (WBC) count at diagnosis, karyotype and smoking status (never vs. ever) were analyzed. Among the 161 males and 119 females with a median follow-up of 12.9 months, 101 (36.1%) had never smoked and 179 (63.9%) were ever smokers. The proportion of patients between never and ever smokers was similar to respect to age, AML presentation, WBC count at diagnosis or karyotype based on univariate analysis of these categorical variables. Never smokers had a significantly longer overall survival (OS) (60.32 months) compared to ever smokers (30.89; p = 0.005). In multivariate analysis incorporating gender, age, AML presentation, WBC count, karyotype and smoking status as covariates, age, karyotype and smoking status retained prognostic value for OS. In summary, cigarette smoking has a deleterious effect on OS in AML.

Is obesity a prognostic factor for acute myeloid leukemia outcome?

Obesity adversely affects outcome in pediatric acute lymphocytic leukemia and acute myeloid leukemia (AML). We asked if obesity, measured by body mass index (BMI), affected outcome in 329 adult AML patients treated with high-dose cytarabine and idarubicin-containing regimens administered according to actual body weight. Age ≥ 60, unfavorable karyotype, secondary AML, and positive smoking status had adverse impact on overall survival in a multivariate analysis, while BMI did not. We conclude that high BMI should not be a barrier to administer high-dose cytarabine-containing regimens for AML induction.

Phase 1 study of arsenic trioxide, high-dose cytarabine, and idarubicin to down-regulate constitutive signal transducer and activator of transcription 3 activity in patients aged <60 years with acute myeloid leukemia.

BACKGROUND: Constitutive activation of signal transducer and activator of transcription-3 (STAT3) was detected in blasts from approximately 50% of patients with acute myeloid leukemia (AML) and was correlated with an adverse outcome. In vitro treatment of AML blasts with arsenic trioxide (ATO) down-regulated STAT3 activity within 6 hours associated with a reduced viability within 48 hours. METHODS: A phase 1 clinical trial to evaluate the biologically effective dose and/or the maximally tolerated dose (MTD) of ATO in vivo in conjunction with high-dose cytarabine (Hidac) and idarubicin (Ida) in patients with AML aged <60 years was conducted. Data were compared with 117 historic AML patients who had received treatment with Hidac/Ida. RESULTS: In total, 61 patients were enrolled onto 11 different dose levels (from 0.01 to 0.65 mg/kg ideal body weight). The MTD was 0.5 mg/kg. Compared with historic controls, patients who received ATO/Hidac/Ida, although they had similar pretreatment characteristics, had better overall survival (P = .039). CONCLUSIONS: ATO priming may have improved the outcome of patients aged <60 years with AML who received Hidac/Ida. The current data suggested that ATO may enhance the effect of chemotherapy. The authors concluded that further studies of this novel combination are warranted.
