Backgrounds: Currently, there is a lack of evidence of prehabilitation during neoadjuvant chemotherapy (NAC) to prevent pneumonia of older patients. This study aimed to investigate the association of preoperative physical fitness after NAC with post-esophagectomy pneumonia in older patients with locally advanced esophageal cancer (LAEC).

Methods: This single-center exploratory prospective cohort study included 80 patients aged ≥ 65 years with LAEC scheduled for curative esophagectomy after NAC between 2021 and 2023.

Background: Home-based rehabilitation involves professional rehabilitation care and guidance offered by physical, occupational, and speech therapists to patients in their homes to help them recuperate in a familiar living environment. The effects on the patient's motor function and activities of daily living (ADLs), and caregiver burden for community-dwelling patients are well-documented; however, little is known about the immediate benefits in patients discharged from the hospital. Therefore, we examined the effects of continuous home-based rehabilitation immediately after discharge to patients who received intensive rehabilitation during hospitalization.

In older patients with locally advanced esophageal cancer (LAEC), loss of skeletal muscle mass during neoadjuvant chemotherapy (NAC) is associated with poor clinical outcomes. This study aimed to investigate factors associated with loss of skeletal muscle mass during NAC in older patients with LAEC. This was a single-center exploratory prospective cohort study.

Objectives: Speech tracking is defined as a complex act or task of listening in which the learner tracks the speech heard and repeats it as accurately as possible while paying attention to incoming contextual information. This ability involves auditory input, speech output, repetition, and divided attention. In this small-scale study, we aimed to use a speech-tracking method to train older adults with hearing loss and examine its effects on hearing loss from multiple perspectives, including hearing handicap, frailty, and neuropsychological testing.

Article Synopsis
  • A nationwide survey in Japan aimed to assess the use of prehabilitation during neoadjuvant chemotherapy (NAC) for patients with advanced esophageal cancer, revealing limited implementation.
  • Out of 155 hospitals surveyed, only 39% offered prehabilitation, with barriers including insufficient human resources, reimbursement issues, and a lack of standardized programs.
  • The study highlights a significant gap in the availability of evidence-based prehabilitation practices, indicating a need for more resources and structured programs for better patient outcomes.

Background: Oral and social problems can exacerbate long-term care. Understanding the relationship between social aspects and oral hypofunction can help identify high-risk factors for long-term care.

Objective: This study aimed to investigate the social aspects of oral hypofunction among medical outpatients.

Vital signs are crucial for assessing the condition of a patient and detecting early symptom deterioration. Noncontact sensor technology has been developed to take vital measurements with minimal burden. This study evaluated the accuracy of a mat-type noncontact sensor in measuring respiratory and pulse rates in patients with cardiovascular diseases compared to conventional methods.

Article Synopsis
  • The study examined how the COVID-19 pandemic affected the daily activities of outpatients with cardiovascular disease (CVD) in Japan after a state of emergency was declared.
  • Researchers surveyed 1,156 CVD patients in fall 2020, comparing their physical activity and sedentary time to pre-pandemic levels across three age groups.
  • Results showed reduced daily steps and increased sedentary time for all age groups, with older adults specifically noting declines in volunteering and daycare use, suggesting a need for tailored interventions based on age.

Background: Recent studies have investigated the effects of exercise on the functional capacity of older adults; training with a balance exercise assist robot (BEAR) effectively improves posture. This study compared the clinical safety and efficacy of training using BEAR video games to conventional resistance training in older adults with cardiovascular disease (CVD).

Methods: Ninety patients (mean age: 78 years) hospitalized due to worsening CVD were randomized to cardiac rehabilitation (CR) Group R (conventional resistance training) or Group B (training using BEAR).

Objectives: In the present study, we performed a detailed analysis of deglutitive dynamics during sleep in patients with obstructive sleep apnea (OSA) using a methodology developed by Sato et al. We hypothesized that the frequency of deglutition would decrease with increasing severity of OSA. The aim of this study is to clarify the involvement of deglutitive dynamics during sleep in OSA by investigating the correlations between deglutition and sleep parameters.

Objectives: In this study, we aimed to investigate the prevalence of oral frailty and explore its relationship with oral function and sarcopenia among older outpatients.

Materials And Methods: In this cross-sectional study, we retrospectively included older patients who visited a frailty outpatient clinic. We assessed total oral frailty employing, among other measures, oral diadochokinesis (/ta/ sound) for tongue-lip movement and tongue pressure.

Objective: To examine the effect of in-bed leg cycling exercise on patients with intensive care unit-acquired weakness (ICU-AW).

Design: Single-center retrospective study.

Subjects/patients: Patients admitted to the ICU between January 2019 and March 2023 were enrolled in the ergometer group, and those admitted to the ICU between August 2017 and December 2018 were enrolled in the control group.

Background: Magnetic stimulation devices can be large because of the need for cooling systems. We developed a compact and lightweight Spinning Permanent Magnet (SPM) device that generates magnetic fields with intensities below the motor threshold. In this report, we present the case of a post-stroke patient in which an immediate reduction in spasticity of the ankle plantar flexors was achieved after SPM treatment.

Background: To determine how to maintain activity in persons with dementia and mild cognitive impairment, we examined the daily activity level by different degrees of clinical severity and sex differences in patients with Alzheimer's disease and mild cognitive impairment.

Methods: This study included 92 patients with Alzheimer's disease and 33 patients with mild cognitive impairment who visited our rehabilitation department. The Frenchay Activities Index was used to assess the level of activity.

Background: The spread of the novel severe acute respiratory syndrome coronavirus 2 infection has been prolonged, with the highly contagious Omicron variant becoming the predominant variant by 2022. Many patients admitted to dedicated coronavirus disease 2019 (COVID-19) wards (COVID-19 treatment units) develop disuse syndrome while being treated in the hospital, and their ability to perform activities of daily living declines, making it difficult for hospitals to discharge them. This study aimed to investigate the relationship between the degree of frailty and home discharge of patients admitted to a COVID-19 treatment units.

Objectives: Non-invasive surface recording devices used for detecting swallowing events include electromyography (EMG), sound, and bioimpedance. However, to our knowledge there are no comparative studies in which these waveforms were recorded simultaneously. We assessed the accuracy and efficiency of high-resolution manometry (HRM) topography, EMG, sound, and bioimpedance waveforms, for identifying swallowing events.
