EDTA-induced pseudothrombocytopenia in hematopoietic stem cell donor.

We herein report a case of peripheral blood stem cell transplantation (PBSCT) involving a donor with EDTA-induced pseudothrombocytopenia (PTCP). The apheresis product was inspected for 24 h and there was no platelet clumping or thrombocytopenia. In the first 14 months after PBSCT, there has been no transfer of PTCP symptoms.

A survey on dogs with valvular disease flying to Japan for operation.

In small-breed dogs, myxomatous mitral valve disease (MMVD) is a common disease which may lead to chronic heart failure. Mitral valve repair is an optimal surgical treatment that is currently available in limited veterinary facilities globally because it requires a special surgery team and specific devices. Therefore, some dogs must travel overseas to undergo this surgery. However, a question arises regarding the safety of dogs when traveling by air with a heart disease. We aimed to evaluate the effect of flight journey on dogs with mitral valve disease, including survival rates, symptoms during the trip, laboratory test results, and operational outcomes. All dogs stayed near the owner in the cabin during the flight. The survival rate after the flight was 97.5% in 80 dogs. The surgical survival rates (96.0% and 94.3%) and hospitalization periods (7 days and 7 days) were similar between overseas and domestic dogs. This report shows that taking air flights in the cabin may not have a significant effect on dogs with MMVD, on the premise that their overall conditions are stable under cardiac medication.

Adverse effects of cell-free and concentrated ascites reinfusion therapy for malignant ascites: a single-institute experience.

BACKGROUND: Cell-free and concentrated ascites reinfusion therapy (CART) is a strategy for improving various intractable symptoms due to refractory ascites, including hypoalbuminemia. CART has recently been applied in the treatment of cancer patients. This study was performed to assess the safety of CART in a single cancer institute. METHODS: We retrospectively reviewed 233 CART procedures that were performed for 132 cancer patients in our institute. RESULTS: The median weight of ascites before and after concentration was 4,720 g and 490 g (median concentration rate, 10.0-fold), The median amounts of total protein and albumin were 64.0 g and 32.6 g (median recovery rates, 44.9% and 49.0%), respectively. Thirty-three adverse events (AEs) were observed in 22 (9.4%) of 233 procedures; 30 of these events occurred after reinfusion. The most common reinfusion-related AEs were fever (13 events) and chills (10 events). Univariate analyses revealed no significant relationships between the frequency of AEs and age, sex, appearance of ascites, weight of harvested and concentrated ascites, the ascites processing rate (filtration and concentration), weight of saline used for membrane cleaning, amount of calculated total protein for infusion, or prophylaxis against AEs; the reinfusion rate of ≥ 125 mL/h or ≥ 10.9 g/h of total protein affected the frequency of AEs, regardless of the prophylactic use of steroids. CONCLUSIONS: The observed AEs were mainly mild reactions after reinfusion, which were related to a reinfusion rate of volume ≥ 125 mL/h, a simple indicator in practice, or total protein ≥ 10.9 g/h. Although our study was retrospective in nature and undertaken in a single institute, this information may be helpful for the management of cancer patients with refractory malignant ascites using CART.

Efficacy of group-based multi-component psycho-education for caregivers of people with dementia: A randomized controlled study.

AIM: The aim of this study was to examine the ability of a group-based multi-component psycho-educational intervention (GMC-PEI) to reduce depression, and improve caregiving appraisals, coping skills of informal caregivers and the condition of people with dementia. METHODS: In this randomized controlled and blinded trial, we enrolled 54 informal caregivers of people with dementia visiting the Japan National Center of Geriatrics and Gerontology, and divided them into GMC-PEI and control groups. The intervention group received a 12-week GMC-PEI program that included six 2-h structured sessions to enhance their knowledge of dementia, caregiving skills and coping skills. The control group received leaflets containing information about dementia. We evaluated caregivers' depression, caregiving time, subjective burden, caregiving appraisal and care coping skills. We also evaluated people with dementia at baseline and 12 weeks, and reassessed 20 participants from the intervention group at 24 and 48 weeks. RESULTS: The GMC-PEI significantly improved depression, positive appraisals of fulfillment in caregiving, affection for care recipients, self-growth and coping skills, such as seeking formal support. Depression, fulfillment and affection for people with dementia showed a peak improvement at 24 weeks; formal support-seeking showed a linear improvement throughout the 48-week follow-up period. CONCLUSIONS: The group-based multi-component psycho-educational intervention reduced depression, improved self-appraisal and enhanced coping skills in caregivers. However, emotional enhancements dissipated sooner than support-seeking skills, suggesting that caregivers should be reviewed every 12-24 weeks. Geriatr Gerontol Int 2021; 21: 561-567.

[Clinical classification of fall risk using visually obtained information at a memory clinic].

AIM: There are few studies concerning the classification of fall risk by nurses without established fall risk assessment tools. In the present study, clinical classification of fall risk using visually obtained information was compared with the assessment of fall risk in order to evaluate the rationale and validity of the clinical classification of fall risk by nurses. METHODS: New patients who visited the center of comprehensive care and research for memory disorders at the National Center for Geriatrics and Gerontology were enrolled in the present study.Day-shift nurses separately recorded the clinical classification of fall risks through visually obtained information during the 10-minutes waiting time for outpatients.Fall risk assessments such as the Fall Risk Index and Timed Up & Go test, were performed by non-nurse medical staffs. Data were analyzed by an independent researcher who was not involved in obtaining clinical information. RESULTS: Nurse's clinical classification of fall risk using visually obtained information correlated well with Fall Risk Index, Timed Up & Go test, One-leg Standing test and Dorsiflex meter. In addition, subjects classified as having high fall risk were more frequently judged to be frail than classes of moderate or little fall-risk. CONCLUSION: Nurse's clinical classification of fall risk using visually obtained information was judged on their integrated impression including their evaluation of the muscle strength, gait speed and balance.

Use of anthropometric indicators in screening for undiagnosed vertebral fractures: a cross-sectional analysis of the Fukui Osteoporosis Cohort (FOC) study.

BACKGROUND: Vertebral fractures are the most common type of osteoporotic fracture. Although often asymptomatic, each vertebral fracture increases the risk of additional fractures. Development of a safe and simple screening method is necessary to identify individuals with asymptomatic vertebral fractures. METHODS: Lateral imaging of the spine by single energy X-ray absorptiometry and vertebral morphometry were conducted in 116 Japanese women (mean age: 69.9 +/- 9.3 yr). Vertebral deformities were diagnosed by the McCloskey-Kanis criteria and were used as a proxy for vertebral fractures. We evaluated whether anthropometric parameters including arm span-height difference (AHD), wall-occiput distance (WOD), and rib-pelvis distance (RPD) were related to vertebral deformities. Positive findings were defined for AHD as > or = 4.0 cm, for WOD as > or = 5 mm, and for RPD as < or = two fingerbreadths. Receiver operating characteristics curves analysis was performed, and cut-off values were determined to give maximum difference between sensitivity and false-positive rate. Expected probabilities for vertebral deformities were calculated using logistic regression analysis. RESULTS: The mean AHD for those participants with and without vertebral deformities were 7.0 +/- 4.1 cm and 4.2 +/- 4.2 cm (p < 0.01), respectively. Sensitivity and specificity for use of AHD-positive, WOD-positive and RPD-positive values in predicting vertebral deformities were 0.85 (95% CI: 0.69, 1.01) and 0.52 (95% CI: 0.42, 0.62); 0.70 (95% CI: 0.50, 0.90) and 0.67 (95% CI: 0.57, 0.76); and 0.67 (95% CI: 0.47, 0.87) and 0.59 (95% CI: 0.50, 0.69), respectively. The sensitivity, specificity, and likelihood ratio for a positive result (LR) for use of combined AHD-positive and WOD-positive values were 0.65 (95% CI: 0.44, 0.86), 0.81 (95% CI: 0.73, 0.89), and 3.47 (95% CI: 3.01, 3.99), respectively. The expected probability of vertebral deformities (P) was obtained by the equation; P = 1-(exp [-1.327-0.040 x body weight +1.332 x WOD-positive + 1.623 x AHD-positive])-1. The sensitivity, specificity and LR for use of a 0.306 cut-off value for probability of vertebral fractures were 0.65 (95% CI: 0.44, 0.86), 0.87 (95% CI: 0.80, 0.93), and 4.82 (95% CI: 4.00, 5.77), respectively. CONCLUSION: Both WOD and AHD effectively predicted vertebral deformities. This screening method could be used in a strategy to prevent additional vertebral fractures, even when X-ray technology is not available.
