Feedbacks Using behaviOral econOmic theories on STEP countS in Cardiovascular Disease Patients (FOOTSTEPS) Using Novel Daily Step Counts Retrieving System.

The effectiveness of gamification-based feedback systems that utilize non-monetary points to promote exercise among cardiovascular disease (CVD) patients has not been fully evaluated. This study aimed to evaluate the effectiveness of a gamification program using non-monetary points on the daily step counts in CVD patients. We collected 30 patients with a history of heart failure or myocardial infarction at a single tertiary center between January 9, 2023, and April 13, 2023. The primary outcome was the change in daily step counts. The baseline step counts were compared with those during the 4-week gamification and the 1-week follow-up period. A total of 29 participants with a mean age of 64.6 years were finally enrolled, and 8 (27.6%) were female. Among them, 23 (79.3%) had a history of old myocardial infarction, and 9 (31.0%) had a history of chronic heart failure. During the intervention period, the average daily step counts increased significantly from baseline in weeks 1-5 (week 1: 1165 steps; 95% CI, 319-2011; P = 0.009, week 2: 1508; 635-2382; P = 0.001, week 3: 1321; 646-1996; P < 0.001, week 4: 1436; 791-2081; P < 0.001, week 5:1148; 436-1860; P < 0.001). Higher body mass index was statistically associated with the smaller difference in step counts from the baseline, and the lower proportion of achievement of step count goals. Female sex was significantly associated with the higher proportion of achievement of step count goals. In conclusion, this pilot prospective interventional study demonstrated the effectiveness of gamification-based feedback systems that utilize non-monetary points to increase daily step counts in CVD patients.

[Thoracic SMARCA4-deficient undifferentiated tumor resembling malignant lymphoma].

We present a case of thoracic SMARCA4-deficient undifferentiated tumor that needed to be differentiated from malignant lymphoma owing to multiple lymph node swelling and marrow involvement. A 52-year-old man developed multiple lymphadenopathies along with anorexia, general fatigue, fever, and sweating 2 months prior to admission. 18F-fluorodeoxyglucose positron emission tomography/computed tomography (PET/CT) scan revealed a mass lesion on the right upper lung, generalized lymph node swelling, and bone metastasis, indicating the presence of suspicious lung cancer; therefore, he was referred to our hospital. Malignant lymphoma was suspected at the time of admission because of elevated levels of lactate dehydrogenase (11,977 U/l) and soluble interleukin 2 receptor (2,152 U/ml) as well as marrow infiltration of large abnormal cells. On day 11, the patient died from rapid respiratory failure. Histological and immunohistochemical features of the pleural effusion cell block led to the diagnosis of thoracic SMARCA4-deficient undifferentiated tumor. Thoracic SMARCA4-deficient undifferentiated tumor was recently introduced in the 2021 World Health Organization classification of lung tumors, with most patients being young adults with a history of heavy smoking and poor prognosis. Because of the multiple lymph node swelling and marrow involvement, this undifferentiated tumor should be distinguished from malignant lymphoma.

Bendamustine-induced rash is associated with a favorable prognosis in patients with indolent B-cell lymphoma.

Bendamustine is now recognized as a key drug for indolent B-cell lymphoma (iBCL), mantle cell lymphoma (MCL) and chronic lymphocytic leukemia (CLL). Skin toxicity associated with bendamustine is one of the characteristic adverse effects. We retrospectively examined the relationship between bendamustine-associated drug rashes and disease prognosis of iBCL and MCL at our institution. Between January 2011 and August 2019, 65 patients (39 men and 26 women, median age 68, range 41-84 years) were treated with bendamustine alone (n=11, 120 mg/m2 on days 1 and 2) or a combination of rituximab and bendamustine (n=54, 90 mg/m2 on days 1 and 2). Of these patients, 47 had follicular lymphoma (FL), 10 had MCL and 8 had other iBCLs. Drug rash occurred in 27 (41.5%). Eight cases (29.6%) were grade 1, 5 (18.5%) were grade 2 and 14 (51.9%) were grade 3. The onset was in the first course in 17 (63.0%), 2nd course in 5 (18.5%), 3rd course in 2 (7.4%), 4th course in 1 (3.7%) and 5th course in 2 (7.4%). No treatment was administered in 1 case (3.7%), topical steroid was applied in 10 (37.0%), antiallergic drug was administered in 2 (7.4%), topical steroid and antiallergic drug were administered in 5 (18.5%), and oral and topical steroid and antiallergic drug were administered in 9 (33.3%). The 3-year progression-free survival (PFS) and overall survival (OS) in patients with rash development were 80.0% and 85.5%, respectively, and those in patients without development were 36.4% and 54.0%, respectively (p=0.009 and 0.02, respectively). By multivariate analysis, the development of rash was associated with a better PFS and a diagnosis of iBCL was associated with a better OS. This study revealed that bendamustine-induced rash is associated with a favorable prognosis among patients with iBCL.

Paravertebral extramedullary hematopoiesis in a case of myelodysplastic syndrome with ring sideroblasts and an SF3B1 mutation.

We present the case of a 56-year-old male patient with paravertebral extramedullary hematopoiesis (EMH) secondary to myelodysplastic syndrome with ring sideroblasts and multilineage dysplasia. In a routine health checkup over 5 years prior, he presented with asymptomatic mild anemia and a posterior mediastinal mass. Pathological and cytomorphological findings of the resected paravertebral mass were similar to those of his bone marrow specimen, and included cellularity with erythroid hyperplasia, multilineage dysplastic changes, and the presence of ring sideroblasts. A concordant SF3B1 mutation was detected in both bone marrow and paravertebral mass samples, suggesting that the EMH cells were derived from the bone marrow.

Prognostic impact of hospital-acquired disability in elderly patients with heart failure.

AIMS: Functional decline is associated with worse outcomes in patients with elderly heart failure (HF), but little is known about the prognostic impact of hospital-acquired disability (HAD) during hospital stay after acute HF. The present study examines the prognostic significance of HAD in the prediction of all-cause mortality in elderly patients who admitted for acute HF. METHODS AND RESULTS: This retrospective study was performed in 1941 elderly patients aged ≥65 years or older from the cardiovascular physiotherapy for acute HF patients in the Tokyo metropolitan area registry and excluded those who died in hospital. HAD was defined as any decline in the Barthel index (BI) before discharge compared with the BI within 1 month before hospital admission. The primary outcome of this study was all-cause death and HF readmission. A total of 565 (29%) deaths and 789 (41%) HF readmission occurred over a median follow-up period of 1.7 years. A total of 476 patients (25%) had HAD during hospital stay after acute HF. In multivariable analysis, HAD predicted all-cause death [hazard ratio (HR): 1.772; 95% confidence interval (CI): 1.450-2.167; P < 60; 0.001] and with risk of HF readmission (HR: 1.193; 95% CI: 1.005-1.416; P = 0.043) after adjusting for the Meta-analysis Global Group in Chronic Heart Failure risk score. CONCLUSIONS: Hospital-acquired disability is associated with an increased risk of all-cause death and readmission for HF in elderly patients with acute HF.

Prognostic impact of peripheral blood Wilms' tumour 1 mRNA expression levels in response to azacytidine in MDS: A single-centre analysis.

To determine the impact of peripheral blood (PB) Wilms' tumour 1 (WT-1) mRNA levels in patients with primary myelodysplastic syndromes (MDS), we analysed the relationships between several clinical variables at the time of diagnosis and the haematological response of patients treated with azacytidine. We observed overall responses in 20 (63%) patients; there were no significant differences in clinical variables, including bone marrow blast counts, IPSS scores and IPSS-R risk scores, between responders and non-responders. The responders' PB WT-1 mRNA levels were significantly lower than those of non-responders (P = 0.03). PB WT-1 mRNA expression could be a marker for predicting the response to azacytidine in patients with de novo MDS.

[Therapy-related acute promyelocytic leukemia developing during chemotherapy for thymic carcinoma].

A 74-year-old man was admitted to hospital due to suspected acute leukemia. He had a history of thymic carcinoma, which had been treated with carboplatin in combination with either paclitaxel or amrubicin. However, the tumor remained unresponsive to these treatments. Administration of tegafur/gimeracil/oteracil (TS-1) was initiated, which resulted in tumor size reduction and a partial response. However, leukopenia persisted after the last TS-1 treatment, and four years after the initial treatment, increased blast cell counts were found in a blood film . Bone marrow analysis showed blasts with Auer rods, faggot cells, and dysplastic promyelocytes. Flow cytometry was positive for CD13, CD33, CD34, CD117, and myeloperoxidase, but negative for HLA-DR. PML-RARA fluorescence in situ hybridization was positive. Cytogenetic analysis revealed 47,XY,t (15;17) (q22;q21),+21. Thus, therapy-related acute promyelocytic leukemia (tAPL) was diagnosed. The patient achieved and maintained complete remission for more than 20 months by a de novo APL-treatment regimen including all-trans retinoic acid, arsenic trioxide and tamibarotene. Moreover, the thymic carcinoma has remained stable. Although secondary malignancies of thymic carcinoma have been previously reported, therapy-related leukemia, especially tAPL, is very rare.

Indolent T-cell lymphoproliferative disorder of the stomach successfully treated by radiotherapy.

Successful treatment of indolent T-cell lymphoproliferative disorder of the gastrointestinal tract (ITLPDGI) by chemotherapy is rare and watchful waiting is often performed for asymptomatic patients. We report a case of ITLPDGI successfully treated by involved field radiotherapy (IFRT). The patient presented with slow ITLPDGI localised to the stomach with mild symptoms. IFRT (30 Gy/20f) was administered, after which endoscopy revealed resolution of lesions and blood vessel appearance, and absence of proliferating abnormal lymphocytes was confirmed by biopsy. The patient remains lymphoma-free 1 year post-treatment. Although long-term follow-up and additional cases are essential for the evaluation of IFRT as a treatment option for localised ITLPDGL, complete remission after relatively low-dose IFRT is promising, particularly as this has been rarely achieved by chemotherapy.

Peripheral T-cell lymphoma with gastrointestinal involvement and indolent T-lymphoproliferative disorders of the gastrointestinal tract.

The 2017 WHO classification includes a new provisional entity of indolent T-lymphoproliferative disorders of the gastrointestinal tract (ITLPD-GIT). We investigated GI involvement of peripheral T-cell lymphoma (PTCL). Eighty-two patients were diagnosed with PTCL during 2007-2017. Eleven patients (13 %) had histologically-confirmed GI tract involvement {3 monomorphic epitheliotropic intestinal lymphoma (MEITL), 3 extranodal NK-/T-cell lymphoma nasal type (ENKL), 2 PTCL, not otherwise specified, 1 adult T-cell leukemia-lymphoma, 2 ITLPD-GIT}. Three patients each had lesions in the small intestine and multiple lesions, two each in the stomach and colon, and one in the duodenum. Six of the 11 patients remained alive. No perforation/stenosis was observed after chemo-radiotherapy, although one patient with ENKL developed gastric bleeding during chemotherapy. One patient with ITLPD-GIT (CD4-/CD8+/Ki67Low) with a colonic lesion showing diffuse edema and multiple aphtha by endoscope and diarrhea, initially diagnosed with MEITL, had active but stable disease after various chemotherapies for 1 year and no therapy for the next 5 years. Another patient with ITLPD-GIT (CD4+/CD8+/Ki67Low) with a localized gastric lesion and slight epigastralgia was in remission for 1 year after radiation. In conclusion, about 10 % of PTCLs were complicated by GI tract lesions and most had a poor prognosis. ITLPD-GIT should be considered as a differential diagnosis based on histology and clinical course. Local complications after chemo/radiotherapy in PTCL with GI involvement were not frequent.

A case series of adult T-cell leukemia-lymphoma, associated with human T-cell leukemia virus type-1, at a single center in a non-viral-endemic metropolitan area.

We examined 13 patients with adult T-cell leukemia-lymphoma (ATL) diagnosed between 2007 and 2018 at a single center in a metropolitan area non-endemic for human T-cell leukemia virus type I (HTLV-1). The median age of the patients (eight male, five female) was 65 years (range, 48-83). The time from onset of symptoms to referral to our center was relatively short (median, 2 months; range, 1-9 months). Upon referral, all patients were suspected to have lymphoma, five were examined for soluble IL-2 receptor and two were examined for anti-HTLV-1 antibody. In ten of the 13 (77%), the patient themselves or their relatives were born in Kyushu. The birth places of the remaining three patients were unknown. Three patients (23%) had family histories of lymphoma. They all exhibited aggressive ATL (five acute, eight lymphoma type); however, the disease status was generally stable, with relatively stable performance status and low scores for prognostic indices. After combination chemotherapy, eight (62%) achieved remission. However, long-term remission was achieved in only one patient with localized lymphoma-type ATL and one young patient after allogeneic hematopoietic stem cell transplantation. In conclusion, at a center in a metropolitan and HTLV-1 non-endemic area in Japan, patients with ATL were relatively young and mainly presented with aggressive subtypes. At initial referral to our center, all 13 patients were suspected of having lymphoma but only two of having ATL. For centers in similar areas of Japan, prompt diagnosis and appropriate treatment of ATL patients will become increasingly necessary following the recent migration of HTLV-1 carriers to non-endemic areas.

Postoperative atrial fibrillation is associated with delayed early rehabilitation after heart valve surgery: a multicenter study.

OBJECTIVE: Postoperative atrial fibrillation (POAF) is a common complication after cardiac surgery. The aim of this multicenter study was to determine the relationship between POAF and patients' progress in early rehabilitation after heart valve surgery. METHODS: We enrolled 302 patients (mean age, 69±10 years) who had undergone heart valve surgery. POAF was monitored using continuous electrocardiogram telemetry, and the Short Physical Performance Battery (SPPB) was used to assess lower-extremity function before surgery and at the time of discharge. Progress in early rehabilitation was evaluated by the duration from the surgery to independent walking. We determined factors associated delayed early rehabilitation and evaluated the interplay of POAF and delayed early rehabilitation in increasing the risk of decline in lower-extremity function from preoperatively to hospital discharge. RESULTS: Multivariate analysis determined POAF to be independent predictors of delayed early rehabilitation after heart valve surgery (OR: 3.906, P = .01). The association between delayed early rehabilitation and decline in lower extremity function was stronger in patients with POAF (OR: 2.73, P = .041) than in those without (OR: 2.22, P = .052). CONCLUSIONS: POAF was clinical predictors of delayed early rehabilitation in patients undergoing heart valve surgery. The combination of POAF with delayed early rehabilitation conferred a high risk of decline in lower-extremity function during hospitalization.

Factors related to physical functioning decline after cardiac surgery in older patients: A multicenter retrospective study.

BACKGROUND: As few studies have examined physical functioning changes after cardiac surgery, the factors related to the decline in physical functioning remain unclear. This study aimed to investigate the factors related to physical functioning decline after cardiac surgery in older patients. METHODS: The final study sample consisted of 523 older (≥65 years) patients (age 74.2±6.1 years, 66% male) who underwent cardiac surgery at 8 Japanese institutions. We excluded patients who were unable to walk independently or had a slow gait speed (<0.8m/s) before surgery, and those who were unable to regain independent walking after surgery. We divided the patients into two groups, a decline-in-gait-speed group and a non-decline-in-gait-speed group, according to whether their gait speed was less than 0.8m/s at discharge. We analyzed patients' clinical characteristics to identify the factors that predicted the postoperative decline in gait speed. RESULTS: Eighty-nine patients (17.0%) showed a postoperative decline in gait speed. Multivariate logistic regression analysis showed that the following factors predicted a postoperative decline in gait speed: age [odds ratio (OR) 1.06, 95% confidence interval (CI) 1.02-1.11]; estimated glomerular filtration rate (OR 0.98, CI 0.96-0.99); preoperative gait speed (OR 0.01, CI 0.00-0.08); and the postoperative day on which the patient could walk independently (OR 1.08, CI 1.02-1.14). CONCLUSIONS: Physical functioning declined in 17% of patients after surgery. The decline could be predicted by several clinical factors, including some that are modifiable. These results suggest that further interventional research on rehabilitation before and after cardiac surgery for older patients might help overcome the decline in physical functioning.

Sarcopenia in adults with congenital heart disease: Nutritional status, dietary intake, and resistance training.

BACKGROUND: This study aimed (1) to assess the nutritional status and dietary intake, (2) compare the body composition and nutritional intake between sarcopenia and non-sarcopenia, and (3) evaluate the effects of resistance training and amino acid intake in adults with congenital heart disease (CHD). METHODS: Study 1 In total, 172 adults with CHD were prospectively enrolled. The Food Frequency Questionnaire was used, and body composition analysis was conducted. Study 2: Thirty of 172 adult patients with CHD were divided into two groups: amino acid intake plus resistance training (group A) and amino acid intake only (group B) for 2 months. RESULTS: Study 1: Skeletal muscle mass index was lower in adults with CHD compared to healthy Japanese. Calorie, protein, and fat intake in adults with CHD was higher than those in the National Nutritive Intake Investigation; however, the difference in carbohydrate or salt intake was non-significant. Study 2: In adults with CHD in group A, body fat percentage, edema index, and N-terminal prohormone of brain natriuretic peptide improved, and body weight, skeletal muscle mass index, and basic metabolism increased after the intervention. There was no improvement after intervention for group B. CONCLUSIONS: According to this study, adults with CHD have higher calorie, protein, and fat intake than those in a national survey despite decreased skeletal muscle mass. Amino acid intake plus resistance training positively improved body fat percentage, skeletal muscle mass, and edema in adults with CHD. Appropriate nutritional education and resistance training guidelines should be provided.

The progression of severe aplastic anemia to hypoplastic leukemia in a long-term observation after the administration of pegylated rHuMGDF.

Thrombopoietin (TPO) is a critical regulator of hematopoiesis. We previously reported that a severe aplastic anemia (SAA) who received a short-term administration of pegylated recombinant human megakaryocyte growth and development factor (rHuMGDF). A trilineage hematologic response was induced, however the patient was diagnosed with leukemia after nine years and eight months from administration of rHuMGDF. In recent reports, somatic mutations in myeloid cancer candidate genes were present in one-third of the AA. A mutant clone may be expanded by rHuMGDF in our patient. The long-term safety of patients treated with TPO and eltrombopag remains unknown. Careful observations are warranted hereafter.

Body composition, appetite-related hormones, adipocytokines, and heart failure in adult patients with congenital heart disease: A preliminary study.

OBJECTIVES: To assess body composition and relationships among body composition, appetite-related hormones, adipocytokines, and heart failure (HF) in adult patients with congenital heart disease (CHD). PATIENTS: This prospective study enrolled 46 consecutive adult patients with CHD and 12 age-matched healthy controls. The patients and control subjects were divided into four groups: 13 patients with Fontan circulation (group A), 16 patients with cyanosis (group B), 17 patients who previously underwent biventricular repair (group C), and 12 age-matched healthy controls. DESIGN: Body composition was measured using InBody730, and levels of appetite-related hormones (ghrelin and leptin) and adipocytokines (leptin, interleukin-6, and tumor necrosis factor-α) were determined. Relationships of these measurements between severe HF, defined as New York Heart Association functional class III-IV and/or recent repeated unscheduled hospitalizations due to HF, were examined using univariate logistic analysis. RESULTS: Mean patient age was 32.1 ± 7.4 years. The skeletal muscle mass was significantly decreased in groups A and B compared with that in controls. Interestingly, ghrelin levels in groups A and B were also significantly lower than those in controls. Univariate logistic analysis revealed that ghrelin level, percent body fat, and pulse oximetric oxygen saturation were significantly associated with severe HF. CONCLUSIONS: Patients with Fontan circulation and those with cyanosis might be at a risk of sarcopenia. Despite the decreased skeletal muscle mass and increased body fat, ghrelin levels in these patients were decreased. These changes might have a negative impact on HF in these patients.

Proposal of criteria for dyserythropoiesis in the diagnosis of myelodysplastic syndromes.

The percentage manifesting dysplasia in bone marrow needed to qualify as significant is ≥10 % in each lineage. However, detailed analyses of this threshold have not been reported. Here, we analyzed dyserythropoiesis (dysE) in 109 myelodysplastic syndromes (MDS) patients with 21 immune thrombocytopenia (ITP)/12 hemolytic anemia (HA) patients as a control. In present study, mild megaloblastic erythroblasts were specifically named 'red cell with abnormal chromatin clumping (RCACC)'. RCACC ≥10 % in erythroblasts was observed in 29 % of ITP patients and 58 % of HA patients. The numbers of MDS patients with RCACC in erythroblasts <10, 10-19 and ≥20 % were 1, 3, and 105, respectively. We analyzed dysE criteria according to the WHO classification (original WHO dysE). Most of our MDS patients (98 %) had original WHO dysE ≥20 %. The ITP patients with original WHO dysE ≥10 % was 48 %, and there were no ITP patients had original WHO dysE ≥20 %. Sixty-seven percent of HA patients had original WHO dysE ≥10 %, and three patients (25 %) had original WHO dysE ≥20 %. Raising the threshold of the original WHO dysE from 10 to 20 or 30 % may provide more suitable criteria. If RCACC is not included in dysE criteria, we think that '10 %' is a suitable threshold for the determination of dyserythropoiesis.

Hematologic improvements in a myelodysplastic syndromes with myelofibrosis (MDS-F) patient treated with azacitidine.

Myelodysplastic syndromes with myelofibrosis (MDS-F) is a poor prognostic hematopoietic disorder. Azacitidine was shown to prolong survival of high-risk MDS patients. However, the effects of azacitidine on MDS-F have yet to be elucidated. Azacitidine was administered to a 74-year-old man with MDS-F at a dose of 75 mg/m(2)/daily subcutaneously for 7 days every 28 days. Hematologic improvements were observed according to the International Working Group 2006 criteria after 8 cycles of the azacitidine treatment, and complete remission was achieved after 14 cycles. The grade of myelofibrosis was also improved. The therapeutic activity of azacitidine was confirmed in our MDS-F patient.

Correlation between dysplastic lineage and type of cytopenia in myelodysplastic syndromes patients with refractory anemia according to the FAB classification.

OBJECTIVES: To analyze the correlation between dysplastic lineage and type of cytopenia in myelodysplastic syndromes. METHODS: We analyzed the correlation between dysplasia and cell count using the data set of our previous morphologic study. RESULTS: There were no correlations between dysgranulopoiesis of 10% or more and absolute neutrophil count (ANC). Similarly, hyposegmented mature neutrophils (Pelger) of 10% or more were not related to ANC. Interestingly, the platelet count of patients with dysmegakaryopoiesis (dys Mgk) was higher than that of patients without dys Mgk (dys Mgk ≥10% vs <10%, P = .08; dys Mgk ≥40% vs <40%, P = .02; micromegakaryocytes ≥10% vs <10%, P = .004). CONCLUSIONS: Since low cell counts did not correlate with the presence of dysplastic features, we suggest that dysplastic features do not directly relate to apoptosis.

[Aplastic anemia complicated with ulcerative colitis].

A 37-year-old female who presented with pancytopenia in April 2008 was diagnosed with aplastic anemia stage 2 with a normal karyotype. She had a PNH phenotype in her red blood cells (RBC) and granulocytes, and HLA DR15. Her aplastic anemia was deteriorated from stage 2 to stage 3, and she required periodic RBC transfusions. Four months after cyclosporine therapy, the pancytopenia improved and she did not need RBC transfusion. However, three months thereafter, she again required RBC transfusions after developing severe ulcerative colitis. Although mesalazine and steroid pulse therapy improved her ulcerative colitis, her transfusion dependency persisted. Eleven months after the diagnosis of aplastic anemia, equine anti-thymocyte globulin (ATG) and cyclosporine were administered, but no hematological improvement was obtained. Six months after the administration of ATG and cyclosporine, transformation to refractory cytopenia with multilineage dysplasia (RCMD) with 7-monosomy was observed. An allogeneic bone marrow transplant (BMT) from a HLA-identical sibling was performed 23 months after the diagnosis of aplastic anemia. Complete remission of both the aplastic anemia and ulcerative colitis was obtained without medication. Although the relationship between aplastic anemia and ulcerative colitis remains unclear, immunological abnormalities might be involved in the pathogenesis of both disorders because she had PNH phenotype in RBC and HLA DR15 and because allogeneic BMT improved both disorders.
