Pre-transplant phase angle as a potential marker for predicting the development of infection after allogeneic hematopoietic stem cell transplantation.

Background & Aims: Nutritional assessment in allogeneic hematopoietic stem cell transplantation (allo-HSCT) is important and decreased skeletal muscle mass is a risk factor for the development of infection. Recently, it has become clear that qualitative rather than skeletal muscle mass loss is a marker that reflects post-transplant outcome, but its association with the development of infection remains unclear. Therefore, we assessed skeletal muscle status by body composition using bioelectrical impedance analysis (BIA) and investigated its association with the development of infection.

Perioperative changes in radiographic density in erector spinae muscle and mortality after lung transplantation.

Rationale: The radiographic density of the erector spinae muscle (ESM) is often decreased early after lung transplantation (LTx). The prognostic impact of this change has not been elucidated.

Objective: To investigate whether the decrease in the radiographic density of ESMs early after LTx is associated with a poor prognosis.

Minimal important difference of the 6-minute walk test after allogenic hematopoietic stem cell transplantation.

Purpose: The 6-min walk test (6MWT) of allogenic hematopoietic stem cell transplantation (allo-HSCT) recipients has been gaining attention; however, minimal differences have not been reported. This study aimed to determine the minimal important difference (MID) in the 6MWT among hospitalized patients with allo-HSCT.

Materials And Methods: The MID of the 6MWT was calculated using three different methodologies based on an anchor-based method; basic anchor-based methods, linear regression analysis, and receiver operating characteristic (ROC) curve analysis.

Evaluating the contribution of fat infiltration in anterior gluteus minimus muscle to walking ability in female with unilateral hip osteoarthritis and candidates for total hip arthroplasty.

Methods: Ninety-one female patients who were diagnosed as the unilateral hip osteoarthritis, classified into Kellgren-Lawrence global scoring system grades 3 or 4, and candidate for total hip arthroplasty were retrospectively reviewed. The horizontally cross-sectional regions of interest for the gluteus medius and anterior and posterior gluteus minimus were manually circumscribed in a single transaxial computed tomography image and muscle density of those regions were obtained.

Effect of gait distance during robot training on walking independence after acute brain injury.

This study aimed to determine whether the distance of gait training using a hybrid assistive limb (HAL) is related to the improvement of walking independence in patients with acute brain injury. This was an exploratory, observational study. Thirty patients having hemiplegia (functional ambulation category, FAC score ≤2) with acute stroke or after brain tumor surgery were included.

Correlation between brain functional connectivity and neurocognitive function in patients with left frontal glioma.

The association between neurocognitive function (NCF) impairment and brain cortical functional connectivity in glioma patients remains unclear. The correlations between brain oscillatory activity or functional connectivity and NCF measured by the Wechsler Adult Intelligence Scale full-scale intelligence quotient scores (WAIS FSIQ), the Wechsler Memory Scale-revised general memory scores (WMS-R GM), and the Western aphasia battery aphasia quotient scores (WAB AQ) were evaluated in 18 patients with left frontal glioma using resting-state electroencephalography (EEG). Current source density (CSD) and lagged phase synchronization (LPS) were analyzed using exact low-resolution electromagnetic tomography (eLORETA).

Belt Electrode-Skeletal Muscle Electrical Stimulation During Early Hematopoietic Post-Transplantation To Prevent Skeletal Muscle Atrophy and Weakness.

A decline in physical functions at the early stage of allogeneic hematopoietic stem cell transplantation (allo-HSCT) is a serious issue. Belt electrode-skeletal muscle electrical stimulation (B-SES) can induce significant muscle contractions with electrical stimulation and reduce muscle weakness. However, this approach has not been used in allo-HSCT patients.

Comparison of international and Japanese predictive equations for maximal respiratory mouth pressures.

Respiratory muscle weakness has attracted attention because sarcopenia and respiratory muscle dysfunction may play a key role in the development of respiratory failure. To evaluate respiratory muscle strength appropriately, individual factors such as sex, age, body size, and ethnicity should be considered. This study aimed to compare equations available in Japan and other countries for predicting respiratory muscle strength.

Intramuscular Adipose Tissue Content Predicts Patient Outcomes after Allogeneic Hematopoietic Stem Cell Transplantation.

During clinical courses involving treatment with allogeneic hematopoietic stem cell transplantation (allo-HSCT), multidisciplinary patient assessment including physical function is indispensable, and quantitative skeletal muscle loss is a poor prognostic marker. Deteriorating quality of muscle from intramuscular adipose tissue degeneration can be important as well, because many patients are cachexic or sarcopenic before allo-HSCT, although this approach has not yet been used in such patients. We conducted this retrospective cohort study to evaluate the quality as well as quantity of skeletal muscle using computed tomography (CT) scans.

Evaluation of indices for predicting recovery of exercise tolerance in patients surviving allogenic hematopoietic stem cell transplantation.

Purpose: Decline in physical function in the early stage after allogeneic hematopoietic stem cell transplantation (allo-HSCT) is a major challenge. Exercise tolerance tests, such as the 6-min walk test, are useful markers for predicting exercise tolerance and various other traits, including cardiometabolic risk and non-relapse mortality. This retrospective cohort study aimed to investigate and identify predictors of recovery of exercise tolerance in the early stage after allo-HSCT.
