ABSTRACT

BACKGROUND: Patients with hematological malignancies received multiple hypodermic injections of recombinant human granulocyte colony-stimulating factor. Procedural pain is one of the most common iatrogenic causes of pain in patients with hematological malignancies. It is also identified as the most commonly occurring problem in clinical care in the Department of Hematology and Oncology at Shenzhen University General Hospital. However, providing immediate relief from pain induced by hypodermic injection of recombinant human granulocyte colony-stimulating factor remains a major challenge. This trial aims to evaluate the safety and analgesic efficacy of a fixed nitrous oxide/oxygen mixture for patients with hematological malignancies and experiencing procedural pain caused by hypodermic injection of recombinant human granulocyte colony-stimulating factor in the department. METHODS: The nitrous oxide/oxygen study is a single-center, randomized, double-blind, placebo-controlled trial involving patients with hematological malignancies who require hypodermic injections of recombinant human granulocyte colony-stimulating factor for treatment. This trial was conducted in the Hematology and Oncology Department of Shenzhen University General Hospital. A total of 54 eligible patients were randomly allocated to either the fixed nitrous oxide/oxygen mixture group (n = 36) or the oxygen group (n = 18). Neither the investigators nor the patients known about the randomization list and the nature of the gas mixture in each cylinder. Outcomes were monitored at the baseline (T0), immediately after hypodermic injection of recombinant human granulocyte colony-stimulating factor (T1), and 5 min after hypodermic injection of recombinant human granulocyte colony-stimulating factor (T2) for each group. The primary outcome measure was the score in the numerical rating scale corresponding to the highest level of pain experienced during hypodermic injection of recombinant human granulocyte colony-stimulating factor. Secondary outcomes included the fear of pain, anxiety score, four physiological parameters, adverse effects, total time of gas administration, satisfaction from both patients and nurses, and the acceptance of the patients. DISCUSSION: This study focused on the safety and analgesic efficacy during hypodermic injection of recombinant human granulocyte colony-stimulating factor procedure. Data on the feasibility and safety of nitrous oxide/oxygen therapy was provided if proven beneficial to patients with hematological malignancies during hypodermic injection of recombinant human granulocyte colony-stimulating factor and widely administered to patients with procedural pain in the department.

ABSTRACT

RATIONALE: Mixed phenotype acute leukemia (MPAL) is a rare and heterogeneous type of leukemia known for its poor prognosis. The optimal treatment strategy for this condition currently lacks consensus, leaving uncertainty in its management. Nonetheless, a potential therapeutic option for patients with refractory MPAL who express target antigens is donor-derived chimeric antigen receptor T (CAR-T) cell therapy. PATIENT CONCERNS: We recently reported a 61-year-old woman with MPAL and elucidated its diagnosis and treatment. DIAGNOSIS: The diagnosis of MPAL was established based on the classification of World Health Organization in 2016. INTERVENTIONS: Despite undergoing 3 different acute lymphoblastic leukemia (ALL) regimens and 1 acute myelogenous leukemia (AML) regimen, the patient did not achieve remission. Subsequently, the patient received human CD19-targeted CAR-T cell therapy. OUTCOMES: The patient achieved a successful and complete remission after CAR-T cell therapy. Tragically, 8 months after CAR-T infusion, the patient experienced a relapse characterized by CD19-negative disease and ultimately passed away. LESSONS: This case underscores the potential efficacy and safety of human-derived CD19 CAR-T cell therapy in treating refractory MPAL. While this particular patient outcome was unfortunate, it suggests that CAR-T cell therapy may still hold promise as a viable treatment option for MPAL patients unresponsive to other therapies. Further research in this field is warranted to determine the most effective treatment strategies for managing this challenging disease.

ABSTRACT

Introduction: Acute pain is a prevalent problem for dementia residents in nursing homes. A variety of intervention strategies have been applied to address this problem. However, there remains an issue of inadequate pain control. This study aims to explore the analgesic efficacy of auricular acupressure (AA) for dementia residents with acute pain in nursing homes. Methods: A multicenter, single-blind, randomized, and sham-controlled clinical trial was performed in three nursing homes in Yinchuan, China. All of the 206 eligible patients with acute pain were randomly divided into two groups for real AA therapy or sham AA (at sham point stimulation) therapy. The primary outcome was measured with a face pain scale revised (FPS-R) score before the procedure, 5 min after the start of the intervention, and 5 min after finishing the procedure. Secondary outcomes covered three physiological parameters, adverse reactions observed, satisfaction level of caregivers, acceptance of patients, and additional use of analgesics. Results: There was a significant difference in pain scores based on FPS-R between the two groups (p < 0.01). Pain score in the true AA group was 1.84 ± 0.23, compared with 2.22 ± 0.81 in the sham AA group. No adverse events were found during the whole procedure for all patients. The satisfaction level of caregivers and acceptance of patients in the real AA group were significantly higher than those in the sham AA group. Conclusion: This study shows that real AA was an alternative analgesic modality in reducing acute pain in patients with mild dementia.

ABSTRACT

In this paper, a topology-based stereo matching method for 3D measurement using a single pattern of coded spot-array structured light is proposed. The pattern of spot array is designed with a central reference ring spot, and each spot in the pattern can be uniquely coded with the row and column indexes according to the predefined topological search path. A method using rectangle templates to find the encoded spots in the captured images is proposed in the case where coding spots are missing, and an interpolation method is also proposed for rebuilding the missing spots. Experimental results demonstrate that the proposed technique could exactly and uniquely decode each spot and establish the stereo matching relation successfully, which can be used to obtain three-dimensional (3D) reconstruction with a single-shot method.

ABSTRACT

Purpose: The chemotherapeutic regimen DCAG (decitabine with cytarabine, aclarubicin hydrochloride, and granulocyte colony-stimulating factor) is effective for elderly patients with acute myeloid leukemia, but recommendations for young patients remain controversial. This study investigated the tolerance and efficacy of DCAG for patients with newly diagnosed acute myeloid leukemia (aged 14-60 years). The clinical features or molecular markers that may predict response to DCAG were identified. Patients and methods: One-hundred sixty-one consecutive patients with newly diagnosed acute myelogenous leukemia received DCAG or standard (idarubicin plus cytarabine, IA) induction chemotherapy (n=64 and 97, respectively). Results: The rates of complete remission after the first cycle, overall survival (OS), and event-free survival (EFS) were comparable. After the second cycle, the complete remission rate of the DCAG group (54.7%) was significantly lower than that of the reference (78.35%, P=0.005). The following were associated with significantly worse OS, and EFS, in the DCAG group: Eastern Cooperative Oncology Group (ECOG) score ≥3 and no response after the second induction therapy; and FLT3-ITD. The multivariate analysis showed the DCAG group with significantly shorter OS associated with ECOG ≥3 and FLT3-ITD. In the DCAG group, after the first cycle of induction chemotherapy the median recovery times of neutrophils and platelets were 15.8 and 13 days. Conclusion: The DCAG and IA groups were similar with regard to complete remission rate after the first cycle, OS, and EFS. The complete remission rate after the second cycle of the DCAG was significantly lower than that of the IA. Grade 4 neutropenia and thrombocytopenia were a major adverse event associated with DCAG.

ABSTRACT

OBJECTIVE: To analyze the clinical manifestations and laboratory features of patients with T large granular lymphocytic leukemia (T-LGLL), so as to improve the understanding of this disease. METHODS: The clinical data of 10 patients with T-LGLL in General Hospital of Chinese PLA from October 2015 to March 2010 were analyzed retrospectively. RESULTS: Their median age at diagnosis was 51 years old. 9/10 (90%) patients showed symptoms of anemia, with a median Hb level of 82.5 g/L, 5/10 (50%) patients combined with autoimmune disorders and with a median Hb level of 77 g/L. 7/10 (70%) patients had splenomegaly, 2/10 (20%) patients had complex karyotype, 2/10 (20%) patients had gene mutations, the median age of 4 patients with complex karyotype and gene mutation was 49 years old, all of them suffered from splenomegaly. The immunophenotype of 6/10 patients was CD3+ CD4- CD8+ and that of 2/10 patients (20%) was CD3+ CD4- CD8-, that of another 2/10 (20%) was CD3+ CD4+ CD8-, the clinical features between different types of immunization were not statistically different. CONCLUSION: T-LGLL patients often are old men, combined with anemia and splenomegaly, often associated with autoimmune diseases; the patients with complex karyotype and gene mutation are younger and they are more with hepatosplenomegaly; the guide role of different immunotypes for clinical strategy is no significant.

ABSTRACT

This study was aimed to observe the clinical efficacy and adverse effects of decitabine plus improved CAG chemotherapy and haploid-identical donor peripheral lymphocyte infusion regimen on elderly patients with myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML). Five elderly patients with MDS and AML were treated with decitabine plus improved CAG chemotherapy and donor peripheral lymphocyte infusion regimen. Examinations on liver and renal function, electrocardiogram and bone marrow analysis were performed before and after treatment, and adverse effects were observed. The results indicated that after a course of treatment by decitabine plus improved CAG chemotherapy and haplo-identical donor peripheral lymphocyte infusion regimen, the total effective rate was 100%, and 4 patients (80%) achieved complete remission, 1 patient achieved partial remission. The dominant clinical adverse effect was bone marrow depression, the median time of neutrophil>0.5×10(9)/L and platelet>20×10(9)/L was 15 d and 16 d respectively for patients without previous MDS. It is concluded that decitabine plus improved CAG chemotherapy and haploid-identical donor peripheral lymphocyte infusion regimen may be effective with less adverse effects for elderly primary AML and high risk MDS patients, it is a promising therapeutic methods and worthy to deeply study.

ABSTRACT

This study was purposed to investigate the clinical efficiencies and adverse reactions of treating the myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML) by using decitabine. The clinical data of 12 MDS and AML patients treated with decitabine were analyzed retrospectively. Among 12 patients there were 1 case of MDS-RA, 2 cases of MDS-RAEB-I, 3 cases of MDS-RAEB-II, 2 cases of AML-M4, 2 cases of AML-M5, 1 case of AML-M6 and 1 case of AML-M0. In decitabine chemotherapy program for 5 days (n = 8), decitabine 20 mg/(m(2)·d) × 5 days was applied, 4 weeks for 1 cycle; in program for 3 days (n = 2), decitabine 15 mg/m(2), once 8 h for 3 days, 6 weeks for 1 cycle; another program (n = 2), decitabine 20 mg/(m(2)·d) every other day for 5 times. For 1 patient achieved complete remission (CR) after treatment with decitabine, ID4 gene methylated level was detected by MS-PCR and ML-PCR before and after treatment. The results showed that 2 cases achieved CR, 1 case partial remission, 5 cases stable disease, 1 case progress of disease and 3 cases died. Disease control rate was 66.67% (8/12), the effective rate 25% (3/12). The average survival time was (11.5 ± 2.1) months. 1-year OS rate was 40%, 2-year OS rate was 16.7%. MS-PCR detection showed that the decitabine could significantly reduce the ID4 gene methylation level. It is concluded that decitabine can stabilize disease status of MDS patients, reduce blood transfusion dependence and improve the life quality of patients, and even some patients who transformed from MDS to leukemia achieved CR after treatment with decitabine. Decitabine can reduce the ID4 gene methylation level. The main adverse reaction of decitabine was myelosuppression, infection and so on. So the blood transfusions, antibiotics and other supportive treatments for these patients are needed. Most of patients well tolerate the adverse effects of decitabine after active symptomatic and supportive treatment. The efficacy and survival rate of patients in this study were similar to that of application of decitabine to treat MDS in other domestic studies.
