OBJECTIVE: To explore whether music intervention improves the quality of life (QOL) of patients undergoing hematopoietic stem cell transplantation (HSCT) and to evaluate its impact on patients\' symptoms of depression/anxiety and fatigue.
METHODS: This systematic review and meta-analysis was conducted in accordance with the Preferred Reporting Items of Systematic reviews and Meta-Analyses (PRISMA) guidelines. The databases PubMed, Cochrane CENTRAL, and EMBASE were searched from inception to September 30, 2022. The search strategy used a combination of the keywords \"music\" and \"hematopoietic stem cell transplantation\" or \"HSCT.\" The outcomes assessed were QOL, depression and anxiety, and fatigue. Pooled standardized mean differences with 95% confidence intervals were calculated to compare the outcomes between the music intervention and control groups. Heterogeneity across the studies was assessed using a chi-square-based test, and the I2 and Q statistics.
RESULTS: Meta-analysis of the included study population showed that music intervention for patients undergoing HSCT was associated with patients\' improved QOL, and resulted in reduced depression/anxiety and fatigue compared to patients without music intervention.
CONCLUSIONS: Music intervention benefits HSCT outcomes, including better QOL, less depression/anxiety, and less fatigue postoperatively. Future trials with larger samples are still warranted to strengthen the evidence supporting the benefits of music intervention in this patient population.

Acute myeloid leukemia (AML) is the second most common hematologic malignancy in children. The incidence of childhood AML is much lower than acute lymphoblastic leukemia (ALL), which makes childhood AML a rare disease in children. The role of genetic abnormalities in AML classification, management, and prognosis prediction is much more important than before. Disease classifications and risk group classifications, such as the WHO classification, the international consensus classification (ICC), and the European LeukemiaNet (ELN) classification, were revised in 2022. The application of the new information in childhood AML will be upcoming in the next few years. The frequency of each genetic abnormality in adult and childhood AML is different; therefore, in this review, we emphasize well-known genetic subtypes in childhood AML, including core-binding factor AML (CBF AML), KMT2Ar (KMT2A/11q23 rearrangement) AML, normal karyotype AML with somatic mutations, unbalanced cytogenetic abnormalities AML, NUP98 11p15/NUP09 rearrangement AML, and acute promyelocytic leukemia (APL). Current risk group classification, the management algorithm in childhood AML, and novel treatment modalities such as targeted therapy, immune therapy, and chimeric antigen receptor (CAR) T-cell therapy are reviewed. Finally, the indications of hematopoietic stem cell transplantation (HSCT) in AML are discussed.

Background: After a hematopoietic stem cell transplantation (HSCT), patients are left with little to no immunity to prevent infections. Importantly, this includes immunity gained from previous exposures, including vaccinations. This loss of immunity is a direct result of previous chemotherapy, radiation, and conditioning regimens the patients receive. It is critical to revaccinate patients post-HSCT to ensure protective immunity against vaccine-preventable diseases. Before 2017, all patients at our institution were referred to their pediatrician at approximately 12-month post-HSCT to be revaccinated. Clinical concern was raised at our institution regarding nonadherence and errors in vaccine schedules. Methods: To understand the magnitude of the problem with revaccination, we performed an internal audit of post-vaccine adherence in patients who received an HSCT between 2015 and 2017. A multidisciplinary team was developed to review the audit results and make recommendations. Results: This audit revealed delays in the initiation of the vaccine schedule, incomplete adherence to the recommended revaccination schedule, and errors in administration. Discussion: Based on the review of the data, the multidisciplinary team recommended an approach for systematic assessment of vaccine readiness and centralization of the administration of vaccines to be done within the stem cell transplant outpatient center.

Objective: Chemotherapy and hematopoietic stem cell transplantation (HSCT) play important roles in clinical etiology, symptoms, signs, imaging findings, and biochemical parameters for inducing posterior reversible encephalopathy syndrome (PRES) in pediatric oncologic diseases. We aimed to evaluate various risk factors of pediatric oncologic diseases after conducting chemotherapy and HSCT to induce PRES for predicting the clinical prognosis frequency. Methods: The literature was performed on PubMed, Web of Science, and Embase databases to recognize the qualified studies. The odds ratios (ORs) of related risk factors and their corresponding 95% confidence intervals (CIs) were used to compute the pooled assessments of the outcomes. Results: Six studies were included in the meta-analysis, involving 828 records. The risk of female children has a significantly higher incidence than male children in oncologic age groups of PRES. Children over the age of 10 years old in oncologic age groups develop a significantly increased risk of PRES. Acute graft-versus-host disease (GVHD) has a significant promotion effect on the occurrence of PRES. Hypertension can promote the occurrence of PRES in children. The risk of PRES in immunodeficient children increases significantly. Children with sickle cell disease (SCD) have a significantly increased risk of PRES. The risk of PRES in children with T-cell leukemia rises considerably. The central nervous system (CNS) leukemia/involvement has a significant role in promoting the occurrence of PRES in children. The pooled OR for the factors male, ≥ 10 years old of age, acute GVHD, hypertension, immunodeficiency, SCD, T-cell leukemia, CNS leukemia/involvement was 0.66 (95% CI: 0.58, 0.76; P < 0.00001), 2.06 (95% CI: 1.23, 3.43; P < 0.006), 1.32 (95% CI: 1.14, 1.53; P < 0.0003), 8.84 (95% CI: 7.57, 10.32; P < 0.00001), 2.72 (95% CI: 1.81, 4.08; P < 0.00001), 2.87 (95% CI: 2.15, 3.83; P < 0.00001), 2.84 (95% CI: 1.65, 4.88; P < 0.0002), and 3.13 (95% CI: 1.43, 6.84; P < 0.004), respectively. Conclusions: The result of this meta-analysis suggests that female children, age over 10 years old, acute GVHD, hypertension, immunodeficiency, SCD, T-cell leukemia, and CNS leukemia/involvement are likely to have the poor outcome in pediatric oncologic/hematologic diseases in PRES.

The efficacy of and indications for hematopoietic stem cell transplantation (HSCT) in pediatric Langerhans cell histiocytosis (LCH) remain undetermined. This retrospective study analyzed 30 children with refractory LCH who underwent HSCT in Japan between 1996 and 2014. Eleven patients received a myeloablative conditioning (MAC) regimen, while 19 patients received a reduced-intensity conditioning (RIC) regimen. Among the 26 patients with complete data, 23 patients had risk organ (RO) involvement during clinical course. Disease status at HSCT was no active disease (NAD) (4), active disease-regression (AD-r) (2), active disease-stable (AD-s) (4), and active disease-progressive (AD-p) (16). Seventeen of the 30 patients (57%) were alive with a median follow-up of 433 days (range 9-5307) after HSCT. Death occurred within 3 months after HSCT in eight of 13 patients. RIC and MAC patients were similar in both overall survival (OS) (56.8% vs. 63.6%, respectively, p = 0.789) and failure-free survival (56.8% vs. 54.6%, respectively, p = 0.938). Regarding disease status at HSCT, the six patients with NAD/AD-r experienced better outcomes than the 20 with AD-s/AD-p (5-year OS, 100% vs. 54.5%, respectively, p = 0.040). Disease state at the time of HSCT was the most important prognostic factor.

Early diagnosis of primary immunodeficiency disorders (PID) is vital and allows directed treatment, especially in syndromes with severe or profound combined immunodeficiency. In PID patients with perinatal CMV or other opportunistic, invasive infections (e.g., Pneumocystis or Aspergillus), multi-organ morbidity may already arise within the first months of life, before hematopoietic stem cell transplantation (HSCT) or gene therapy can be undertaken, compromising the definitive treatment and outcome. Deficiency of Wiskott-Aldrich syndrome (WAS) protein-interacting protein (WIP deficiency) causes an autosomal recessive, WAS-like syndrome with early-onset combined immunodeficiency that has been described in three pedigrees to date. While WAS typically includes combined immunodeficiency, microthrombocytopenia, and eczema, the clinical and laboratory phenotypes of WIP-deficient patients-including lymphocyte subsets, platelets, lymphocyte proliferation in vitro, and IgE-varied widely and did not entirely recapitulate WAS, impeding early diagnosis in the reported patients. To elucidate the phenotype of WIP deficiency, we provide a comprehensive synopsis of clinical and laboratory features of all hitherto-described patients (n = 6) and WIP negative mice. Furthermore, we summarize the treatment modalities and outcomes of these patients and review in detail the course of one of them who was successfully treated with serial, unconditioned, maternal, HLA-identical donor lymphocyte infusions (DLI) against life-threatening, invasive CMV infection, followed by a TCRαβ/CD19-depleted, treosulfan/melphalan-conditioned, peripheral blood HSCT and repetitive, secondary-prophylactic, CMV-specific DLI with 1-year post-HSCT follow-up. This strategy could be useful in other patients with substantial premorbidity, considered \"too bad to transplant,\" who have an HLA-identical family donor, to eliminate infections and bridge until definitive treatment.

The skin is the most common organ system involved in patients with systemic sclerosis (SSc). Nearly all patients experience cutaneous symptoms, including sclerosis, Raynaud\'s phenomenon, digital ulcers, telangiectasias, and calcinosis. In addition to posing functional challenges, cutaneous symptoms are often a major cause of pain, psychological distress, and body image dissatisfaction. The present article reviews the main features of SSc-related cutaneous manifestations and highlights an evidence-based treatment approach for treating each manifestation. This article also describes novel treatment approaches and opportunities for further research in managing this important clinical dimension of SSc.
