Abstract

Abstract Background Osteoarthritis (OA) is common in aged adults and can result in muscle weakness and function limitations in lower limbs. Knee OA affects the quality of life in the elderly. Technology-supported feedback to achieve lower impact on knee joints and individualized exercise could benefit elderly patients with knee OA. Herein, a computer-aided feedback rowing exercise system is proposed, and its effects on improving muscle strength, health conditions, and knee functions of older adults with mild knee OA were investigated. Methods Thirty-eight older adults with mild knee OA and satisfying the American College of Rheumatology (ACR) clinical criteria participated in this randomized controlled clinical trial. Each subject was randomly assigned to a computer-aided rowing exercise (CRE) group (n = 20) or a control group (CON) (n = 18) that received regular resistance exercise programs two times per week for 12 weeks. Outcome measurements, including the Western Ontario and MacMaster Universities (WOMAC), muscle strength and functional fitness of the lower limbs, were evaluated before and after the intervention. Results Participants’ functional fitness in the CRE group exhibited significantly higher adjusted mean post-tests scores, including the WOMAC (p = 0.006), hip abductors strength (kg) (MD = 2.36 [1.28, 3.44], p = 5.67 × 10–5), hip adductors strength (MD = 3.04 [1.38, 4.69], p = 0.001), hip flexors strength (MD = 4.01 [2.24, 5.78], p = 6.46 × 10−5), hip extensors strength (MD = 2.88 [1.64, 4.12], p = 4.43 × 10−5), knee flexors strength (MD = 2.03 [0.66, 3.41], p = 0.005), knee extensors strength (MD = 1.80 [0.65, 2.94], p = 0.003), and functional-reach (cm) (MD = 3.74 [0.68, 6.80], p = 0.018), with large effect sizes (η2 = 0.17–0.42), than those in the CON group after the intervention. Conclusions Older adults with knee OA in the CRE group exhibited superior muscle strength, health conditions, and functional fitness improvements after the 12-week computer-aided rowing exercise program than those receiving the conventional exercise approach. Trial registration The Institutional Review Board of the Taipei Medical University approved the study protocol (no. N201908020, 27/05/2020) and retrospectively registered at ClinicalTrials.gov (trial registry no. NCT04919486, 09/06/2021).

Abstract

Aims To evaluate the effects of a simulation-based education programme on critical care nurses' knowledge, confidence, competence and clinical performance in providing delirium care. Design Single-blinded randomized controlled trial. Methods Registered nurses who work in intensive care units were recruited from a university-affiliated acute major metropolitan teaching hospital. The intervention group received: (i) five online-learning delirium care videos, (ii) one face-to-face delirium care education session and (iii) a simulation-based education programme with a role-play scenario-based initiative and an objective structured clinical examination. The control group received only online videos which were the same as those provided to the intervention group. Delirium care knowledge, confidence, competence, and clinical performance as outcomes were collected at: baseline, immediately after intervention, and within 6 weeks post-intervention to test whether there were any changes and if they were sustained over time. Data were collected between 2 October and 29 December 2020. The repeated-measures analysis of variance was used to examine for changes in delirium care knowledge, confidence, and competence within groups. Results Seventy-two critical care nurses participated with 36 each allocated to the intervention group and control group. No statistically significant difference was observed between the two groups in outcome variables at 6 weeks post-intervention. In the intervention group, significant within-group changes were observed in terms of delirium care knowledge, confidence, and competence over time. By contrast, no significant changes were observed in outcome measures over time in the control group. Conclusion The simulation-based education programme is an effective and feasible strategy to improve delirium care by enhancing the knowledge, confidence, competence and clinical performance of critical care nurses. Impact Our findings provide evidence regarding the development and implementation of a simulation-based education programme in hospitals for health professional education in Taiwan.

Abstract

The aim of this study was to determine if aromatherapy could reduce preoperative anxiety in ambulatory surgery patients. A total of 109 preoperative patients were randomly assigned to experimental (bergamot essential oil) and control (water vapor) conditions and their responses to the State Trait Anxiety Inventory and vital signs were monitored. Patients were stratified by previous surgical experience, but that did not influence the results. All those exposed to bergamot essential oil aromatherapy showed a greater reduction in preoperative anxiety than those in the control groups. Aromatherapy may be a useful part of a holistic approach to reducing preoperative anxiety before ambulatory surgery.

Abstract

Free radicals and lipid peroxides, both of which are easily formed in the diabetic state, play an important role in the development of diabetic complications. Antioxidative therapy may help prevent diabetic complications caused by lipoperoxidation and free-radical formation in diabetes mellitus (DM). A number of findings suggest that oxidative stress exists in persons with high-risk DM. Auricular pellet acupressure has reportedly been an effective treatment method for a variety of medical conditions, including anxiety, juvenile myopia, essential hypertension, and senile vascular dementia. However, its effects on antioxidative enzymes have not been elucidated. We therefore evaluated the impact of auricular pellet acupressure on antioxidative status in persons with high-risk DM.Our study involved 69 persons with high-risk DM, who were allocated either to undergo acupressure as active treatment for the experimental group or to a control group.The experimental group in the study received auricular pellet acupressure three times daily for 5 consecutive days. After a 2-day rest period, the procedure was performed on the contralateral ear. Acupressure was performed twice on each ear, with each application followed by its application to the contralateral ear, over a total treatment period of 20 days. The control groups did not undergo auricular pellet acupressure.At the end of the 20-day period of treatment of the experimental group, blood was collected from all of the study participants for assay of serum superoxide dismutase (SOD) and catalase concentrations, as was also done for the control group.Serum concentrations of SOD (p0.05) and catalase (p0.0001) were significantly higher in the experimental group than in the control group.Our findings suggest that auricular pellet acupressure can increase the concentration of antioxidative enzymes in persons with high-risk DM.

Abstract

DNMT3Amutations are associated with poor prognosis in acute myeloid leukemia (AML), but the stability of this mutation during the clinical course remains unclear. In the present study of 500 patients with de novo AML, DNMT3Amutations were identified in 14% of total patients and in 22.9% of AML patients with normal karyotype. DNMT3Amutations were positively associated with older age, higher WBC and platelet counts, intermediate-risk and normal cytogenetics, FLT3internal tandem duplication, and NPM1, PTPN11, and IDH2mutations, but were negatively associated with CEBPAmutations. Multivariate analysis demonstrated that the DNMT3Amutation was an independent poor prognostic factor for overall survival and relapse-free survival in total patients and also in normokaryotype group. A scoring system incorporating the DNMT3Amutation and 8 other prognostic factors, including age, WBC count, cytogenetics, and gene mutations, into survival analysis was very useful in stratifying AML patients into different prognostic groups (P< .001). Sequential study of 138 patients during the clinical course showed that DNMT3Amutations were stable during AML evolution. In conclusion, DNMT3Amutations are associated with distinct clinical and biologic features and poor prognosis in de novo AML patients. Furthermore, the DNMT3Amutation may be a potential biomarker for monitoring of minimal residual disease.

Abstract

The studies concerning clinical implications of TET2mutation in patients with primary acute myeloid leukemia (AML) are scarce. We analyzed TET2mutation in 486 adult patients with primary AML. TET2mutation occurred in 13.2% of our patients and was closely associated with older age, higher white blood cell and blast counts, lower platelet numbers, normal karyotype, intermediate-risk cytogenetics, isolated trisomy 8, NPM1mutation, and ASXL1mutation but mutually exclusive with IDHmutation. TET2mutation is an unfavorable prognostic factor in patients with intermediate-risk cytogenetics, and its negative impact was further enhanced when the mutation was combined with FLT3-ITD, NPM1-wild, or unfavorable genotypes (other than NPM1+/FLT3-ITD−or CEBPA+). A scoring system integrating TET2mutation with FLT3-ITD, NPM1, and CEBPAmutations could well separate AML patients with intermediate-risk cytogenetics into 4 groups with different prognoses (P< .0001). Sequential analysis revealed that TET2mutation detected at diagnosis was frequently lost at relapse; rarely, the mutation was acquired at relapse in those without TET2mutation at diagnosis. In conclusion, TET2mutation is associated with poor prognosis in AML patients with intermediate-risk cytogenetics, especially when it is combined with other adverse molecular markers. TET2mutation appeared to be unstable during disease evolution.

Abstract

The impact of WT1mutations in acute myeloid leukemia (AML) is not completely settled. We aimed to determine the clinical implication of WT1mutation in 470 de novo non-M3 AML patients and its stability during the clinical course. WT1mutations were identified in 6.8% of total patients and 8.3% of younger patients with normal karyotype (CN-AML). The WT1mutation was closely associated with younger age (P< .001), French-American-British M6 subtype (P= .006), and t(7;11)(p15;p15) (P= .003). Multivariate analysis demonstrated that the WT1mutation was an independent poor prognostic factor for overall survival and relapse-free survival among total patients and the CN-AML group. A scoring system incorporating WT1mutation, NPM1/FLT3-ITD, CEBPAmutations, and age into survival analysis proved to be very useful to stratify CN-AML patients into different prognostic groups (P< .001). Sequential analyses were performed on 133 patients. WT1mutations disappeared at complete remission in all WT1-mutated patients studied. At relapse, 3 of the 16 WT1-mutated patients who had paired samples lost the mutation and 2 acquired additional mutations, whereas 3 of 110 WT1-wild patients acquired novel mutations. In conclusion, WT1mutations are correlated with poor prognosis in AML patients. The mutation status may be changed in some patients during AML progression.

Abstract

Somatic mutation of the AML1/RUNX1(RUNX1) gene is seen in acute myeloid leukemia (AML) M0 subtype and in AML transformed from myelodysplastic syndrome, but the impact of this gene mutation on survival in AML patients remains unclear. In this study, we sought to determine the clinical implications of RUNX1mutations in 470 adult patients with de novo non-M3 AML. Sixty-three distinct RUNX1mutations were identified in 62 persons (13.2%); 32 were in N-terminal and 31, C-terminal. The RUNX1mutation was closely associated with male sex, older age, lower lactic dehydrogenase value, French-American-British M0/M1 subtypes, and expression of HLA-DR and CD34, but inversely correlated with CD33, CD15, CD19, and CD56 expression. Furthermore, the mutation was positively associated with MLL/PTDbut negatively associated with CEBPAand NPM1mutations. AML patients with RUNX1mutations had a significantly lower complete remission rate and shorter disease-free and overall survival than those without the mutation. Multivariate analysis demonstrated that RUNX1mutation was an independent poor prognostic factor for overall survival. Sequential analysis in 133 patients revealed that none acquired novel RUNX1mutations during clinical courses. Our findings provide evidence that RUNX1mutations are associated with distinct biologic and clinical characteristics and poor prognosis in patients with de novo AML.

Abstract

The development of acute myeloid leukemia (AML) is a multistep process. Recently, somatic mutations of PTPN11, the gene encoding non-receptor protein tyrosine phosphatase SHP-2, were observed in some hematological malignancies. However, the characteristics of adult AML with PTPN11mutations have not been comprehensively studied, and the specific genetic alteration cooperative with a PTPN11mutation in the leukemogenesis remains largely unknown. In this study, PTPN11mutation and its association with other gene aberrations were analysed for 272 adult patients with de novoAML. Missense mutations were identified in 14 individuals (5.1%). The PTPN11mutation was closely associated with old age (P=0.036), FAB M4/M5 subtypes (P=0.049), CD14 expression (P=0.026), a normal karyotype (P=0.044) and NPM1mutation (P=0.037), but negatively associated with FLT3/ITD (P = 0.025). In addition, four patients revealed simultaneous mutations of PTPN11and AML1(n=3) or MLL(n=1). We observed a shorter overall survival for patients with PTPN11mutation than those without amongst NPM1-wild patients (P=0.001), but not amongst NPM1-mutated patients (P=0.738). Our findings provide evidence that AML patients with PTPN11mutations had some distinct biological and clinical characteristics, and the mutation may cooperate with other gene alterations to lead to AML in a subset of patients.

Abstract

CXC chemokine receptor 4 (CXCR4) is an essential regulator for homing and maintenance of hematopoietic stem cells within the bone marrow niches. Analysis of clinical implications of bone marrow CXCR4 expression in patients with acute myeloid leukemia showed not only higher CXCR4 expression was an independent poor prognostic factor, irrespective of age, white blood cell counts, cytogenetics, and mutation status of NPM1/FLT3-ITD and CEBPA, but also showed CXCR4 expression was inversely associated with mutations of CEBPA, a gene encoding transcription factor C/EBPα. Patients with wild-type CEBPA had significantly higher CXCR4 expression than those with mutated CEBPA. We hypothesized that CEBPA might influence the expression of CXCR4. To test this hypothesis, we first examined endogenous CXCR4 expression in 293T and K562 cells over-expressing wild-type C/EBPα p42 and demonstrated that CXCR4 levels were increased in these cells, whilst the expression of the N-terminal mutant, C/EBPα p30, diminished CXCR4 transcription. We further showed p42 was bound to the CXCR4 promoter by the chromatin immunoprecipitation assays. Induction of p42 in the inducible K562-C/EBPα cell lines increased the chemotactic migration. Moreover, decreased expression of C/EBPα by RNA interference decreased levels of CXCR4 protein expression in U937 cells, thereby abrogating CXCR4-mediated chemotaxis. Our results provide, for the first time, evidence that C/EBPα indeed regulates the activation of CXCR4, which is critical for the homing and engraftment of acute myeloid leukemia cells, while p30 mutant impairs CXCR4 expression., (Copyright© Ferrata Storti Foundation.)
