Article Synopsis
  • Inspiratory muscle training (IMT) may enhance recovery in hospitalized patients with acute decompensated heart failure (ADHF) by improving their walking ability compared to standard cardiac rehabilitation (CR) alone.
  • A study found that patients participating in IMT showed a significantly greater increase in their 2-minute walking distance compared to a historical control group, indicating that IMT could be beneficial.
  • The IMT sessions were deemed safe, with very few adverse events, suggesting that integrating IMT into CR could offer a promising new strategy for aiding recovery in these patients.

Background: Tacrolimus is an immunosuppressant administered to patients undergoing lung transplantation. Itraconazole is often concomitantly used with tacrolimus to prevent fungal infections and increase tacrolimus concentration. However, the pharmacokinetics of tacrolimus in Japanese lung transplant recipients and the effect of itraconazole on its pharmacokinetics have not been adequately evaluated.

Purpose: Low physical function can be effectively improved via intradialytic exercise. However, the association between the effects of intradialytic exercise on physical function and malnutrition severity has not been studied extensively. This study aimed to investigate the impact of nutritional status severity on physical function in patients undergoing hemodialysis with low physical function to whom intradialytic exercise was prescribed.

Purpose: Exercise therapy is a crucial intervention for improving health-related quality of life (HRQOL) in patients undergoing haemodialysis. However, factors that improve HRQOL by improving physical function and dialysis-related symptoms remain unknown. This study aimed to examine the physical function parameters and dialysis-related symptoms that improve HRQOL following intradialytic exercise.

Introduction: Intradialytic exercise is essential for improving physical function for older patients. This study aimed to examine the relationship between the effects of exercise therapy and aging.

Methods: This multicenter cohort study included 1176 patients aged 40-89 years, who participated in an intradialytic exercise program, comprising stretching and resistance training, three times per week for 12 months.

This study aimed to investigate the basic data on the effectiveness and safety of the system in healthy subjects using an immersive virtual reality (VR) exercise system specialized for therapeutic exercise therapy during dialysis or hospital use. A total of 15 healthy adult subjects performed four exercises, namely lifting and rowing exercises using VR and each movement exercise without VR (control). The simulator sickness questionnaire (SSQ) was administered pre- and post-operatively to assess for VR sickness.

Background: Physical performance improvement through whole-body exercise may have a positive impact on dysphagia via improvement of maximum tongue pressure (MTP).

Aims: The present study aimed to quantitatively analyze whether improvement in physical performance reduces dysphagia by improving MTP in patients with acute heart failure (AHF).

Methods: A total of 146 patients with AHF and dysphagia were included.

Dysphagia in patients with heart failure leads to poorer outcomes during hospitalization and after discharge. Therefore, addressing dysphagia is critical for improving patient prognosis. This retrospective observational study aimed to evaluate associations between improvements in swallowing dysfunction at the time of hospital discharge and the physical function, cognitive function, nutritional status, and maximum tongue pressure (MTP).

Objective: Intradialytic exercise improves physical function. However, malnutrition may be an essential factor affecting the effectiveness of exercise to improve physical function. Few studies of the relationship between malnutrition and the effectiveness of intradialytic exercise to improve physical function exist.

Article Synopsis
  • * A total of 360 patients aged 65 and older were analyzed, revealing that those with dysphagia tended to be older, have a lower body mass index, and exhibit reduced physical and cognitive skills compared to those without dysphagia.
  • * The findings indicated that after adjustments, patients with dysphagia had a significantly higher prevalence of HAD (61.9% vs. 42.9%) and dysphagia was identified as an independent predictor of developing HAD, aiding in risk assessment for future cases.

Background: Cardiac rehabilitation (CR) is commonly performed in patients with heart failure (HF) with mild cognitive impairment (MCI). However, whether MCI diminishes the benefit of early phase II CR is unclear.

Aim: This study aimed to clarify whether MCI diminishes the benefit of early phase II CR in patients hospitalized for HF.

Article Synopsis
  • * Researchers analyzed data from 224 patients using various assessments, finding that nearly 30% experienced a drop in independence during hospitalization, but most regained it by discharge.
  • * Results highlight that patients with both dysphagia and malnutrition face a higher risk of not fully recovering their daily living abilities after treatment, emphasizing the importance of early detection and intervention.

Immunoglobulin A (IgA)-albumin complexes may be associated with pathophysiology of multiple myeloma, although the etiology is not clear. Detailed structural analyses of these protein-protein complexes may contribute to our understanding of the pathophysiology of this disease. We analyzed the structure of the IgA-albumin complex using various electrophoresis, mass spectrometry, and in silico techniques.
