Early Mobilization Using a Mobile Patient Lift in the ICU: A Randomized Controlled Trial.

OBJECTIVES: To ascertain whether a mobile patient lift facilitates early mobilization in ventilated ICU patients. DESIGN: A single-center, open-label, randomized controlled trial. SETTING: An academic ICU in Tokyo. PATIENTS: Eighty patients were admitted to ICU and expected ventilation for at least 48 hours. INTERVENTIONS: In the intervention group, in addition to the rehabilitation protocol received by the control group, patients were assisted in sitting, standing, transfers, and walking using the mobile patient lift. MEASUREMENTS AND MAIN RESULTS: The intervention group predominantly stood faster than the control group (1.0 vs. 3.0 d, p < 0.01). The Intervention group also had significantly higher Functional Status Score-ICU scores at ICU discharge. However, the Medical Research Council score and Barthel index at discharge, length of ICU stay, and number of ventilator-free days did not differ between the two groups. CONCLUSIONS: The use of mobile patient lifts facilitates the earlier standing of patients on ventilators. This may contribute to patients improved physical function in the ICU. TRIAL REGISTRATION: The study protocol was registered with the University Hospital Medical Information Network (UMIN) under the registration number UMIN000044965. Registered July 30, 2021.

Molecular and Neural Mechanism of Dysphagia Due to Cancer.

Cancer is one of the most common causes of death worldwide. Along with the advances in diagnostic technology achieved through industry-academia partnerships, the survival rate of cancer patients has improved dramatically through treatments that include surgery, radiation therapy, and pharmacotherapy. This has increased the population of cancer "survivors" and made cancer survivorship an important part of life for patients. The senses of taste and smell during swallowing and cachexia play important roles in dysphagia associated with nutritional disorders in cancer patients. Cancerous lesions in the brain can cause dysphagia. Taste and smell disorders that contribute to swallowing can worsen or develop because of pharmacotherapy or radiation therapy; metabolic or central nervous system damage due to cachexia, sarcopenia, or inflammation can also cause dysphagia. As the causes of eating disorders in cancer patients are complex and involve multiple factors, cancer patients require a multifaceted and long-term approach by the medical care team.

Impact of Controlling Nutritional Status Score on Mortality in Elderly Patients with Idiopathic Pulmonary Fibrosis.

Background: There are only a few reports on the nutritional status and mortality of patients with idiopathic pulmonary fibrosis (IPF). As such, this study aims to investigate the relationship between controlling nutritional status (CONUT) and the mortality of elderly patients with IPF. Methods: A total of 170 IPF patients aged ≥65 years old who visited the rehabilitation department of our hospital between July 2014 and July 2021 (mean age: 75.7 ± 6.3 years, sex (male/female): 138/32, %FVC: 78.3 ± 18.3%) were retrospectively analyzed. The Kaplan-Meier method and log-rank test were applied. Furthermore, using a Cox proportional hazards model with multivariate analysis, we analyzed the relationship between all-cause mortality and baseline characteristics including CONUT. Results: Based on the CONUT score, the normal group included 101 cases, the mild group included 58 cases, the moderate group included 11 cases, and the severe group had 0 cases. There were 49 cases of all-cause mortality events, suggesting that the mortality of the moderate group was significantly poorer than that of the normal and mild groups (p < 0.05). Furthermore, multivariate analysis identified GAP stage (HR: 5.972, 95%CI: 2.901~12.291, p < 0.0001), mMRC scale (HR: 0.615, 95%CI: 0.389~0.971, p = 0.009), and CONUT (HR: 2.012, 95%CI: 1.192~3.395, p = 0.037) as factors significantly influencing mortality. Conclusions: Severe malnutrition was not observed in elderly patients with IPF. Moderate malnutrition was associated with a significantly higher risk of all-cause mortality, suggesting that CONUT is an important indicator for predicting mortality.

A preliminary study on the effects of long-term robot suit exercise training on gait function and quality of life in patients with spinal and bulbar muscular atrophy.

Spinal and bulbar muscular atrophy (SBMA) progressively impairs gait function, resulting in the need for patients to use a wheelchair approximately 20 years after onset. No reports have investigated the effects of long-term exercise training using the Hybrid Assisted Limb (HAL) in patients with multiple SBMA. This study investigated the effects of long-term exercise training using HAL in patients with SBMA and its effects on the quality of life (QoL). Six courses of HAL treatment were administered to three males with SBMA, and leuprorelin was administered to each patient. Each course had a 4-5 week duration, during which the treatment was performed nine times, with a rest period of at least 2 months between each course. A 2-minute walk test (2MWT) and a 10-m walk test (10MWT) were performed to measure gait ability, and a blood test to measure the serum creatine kinase (CK) and creatinine (CRE) levels was performed before and after each course of treatment. We evaluated QoL using the Medical Outcomes Study 36-Item Short Form Health Survey (SF-36). The average 2MWT distance improved over 2 years (p = 0.038), and the 10MWT showed neither improvement nor decline. No increase or decrease in serum CK or CRE levels was observed. There were no significant changes in the SF-36 physical, mental, or social summary scores. In combination with leuprorelin therapy, robot-assisted training using HAL maintained gait ability and QoL in patients with SBMA for 2 years.

L-Menthol Olfactory Stimulation Reduced Dyspnea Sensation during the 6 min Walk Test in Patients with Chronic Breathlessness Syndrome: A Pilot Study.

There are very limited methods of relieving dyspnea that are independent of the causative disease. L-menthol olfactory stimulation is reported to be effective for dyspnea during exercise and inspiratory resistance. Therefore, we examined the effects of L-menthol olfactory stimulation on exertional dyspnea during the 6 min walking distance test (6MWT) in patients with chronic breathlessness syndrome. The subjects who consented to the study were divided into two groups. In Group A, the first 6MWT was performed as usual (placebo) while wearing a surgical mask, and the second 6MWT was performed under the L-menthol condition. In Group B, the first 6MWT was performed under the L-menthol condition, and the second 6MWT was performed as a placebo. A total of 16 subjects (70.8 ± 9.5 years) were included in the analysis. As for the effect of reducing dyspnea, a significant difference was observed in Group A patients who underwent the L-menthol condition in the second 6MWT (p = 0.034). In the comparison of the 6 min walking test under the L-menthol condition and the placebo, the modified Borg scale gain was significantly different between the L-menthol condition and the placebo (p = 0.007). Our results suggested that the L-menthol olfactory stimulation reduced dyspnea on exertion in patients with chronic breathlessness syndrome.

[Phototherapy in rehabilitation medicine].

Rehabilitation can be classified into four types: medical, vocational, educational, and social rehabilitation. The goal of medical rehabilitation is to maintain and improve a patient's physical and mental capabilities. Phototherapy is an important means of treatment in rehabilitation medicine and is usually performed with ultraviolet, infrared, or laser light. Among them, laser light has been shown to have various biological effects, such as increasing blood flow, promoting wound healing, reducing inflammation, and improving immune function. Laser therapy is as important a treatment option as exercise therapy in rehabilitation medicine, and is considered to be worth evaluating as a therapeutic means to relieve pain in musculoskeletal disorders, promote healing in peripheral neuropathy, and alleviate muscle spasticity.

Are Oropharyngeal Dysphagia Screening Tests Effective in Preventing Pneumonia?

Oropharyngeal dysphagia, a clinical condition that indicates difficulty in moving food and liquid from the oral cavity to the esophagus, has a markedly high prevalence in the elderly. The number of elderly people with oropharyngeal dysphagia is expected to increase due to the aging of the world's population. Understanding the current situation of dysphagia screening is crucial when considering future countermeasures. We report findings from a literature review including citations on current objective dysphagia screening tests: the Water Swallowing Test, Mann Assessment of Swallowing Ability, and the Gugging Swallowing Screen. Pneumonia can be predicted using the results of the screening tests discussed in this review, and the response after the screening tests is important for prevention. In addition, although interdisciplinary team approaches prevent and reduce aspiration, optimal treatment is a challenging. Intervention studies with multiple factors focusing on the elderly are needed.

Persistence of the Postoperative Change in the Six-minute Walking Distance of Lung Cancer Patients with Chronic Obstructive Pulmonary Disease.

OBJECTIVES: The aim of this prospective follow-up study was to investigate the difference before and after surgery in the six-minute walking distance (6MD) of lung cancer patients with chronic obstructive pulmonary disease (COPD) and to examine the long-term effect of the change in 6MD in the early postoperative period. METHODS: This was a retrospective analysis of 25 COPD patients who underwent lung cancer surgery and perioperative rehabilitation in our department. Assessments of 6WD were carried out preoperatively and at 1, 3, and 6 months postoperatively. The changes in 6MD at 1, 3, and 6 months postoperatively compared with the preoperative value were designated the 1-month Δ6MD, the 3-month Δ6MD, and the 6-month Δ6MD, and the associations between them were investigated. RESULTS: The mean 6MD distance was 412.0±27.3 m (95% confidence interval) preoperatively, 369.0±33.8 m at 1 month, 395.6±32.2 m at 3 months, and 400.0±38.2 m at 6 months, with a significant difference between the preoperative and 1-month values (P<0.01). There were strong correlations between 1-month and 3-month Δ6MDs (r =0.74, P<0.0001) and between 1-month and 6-month Δ6MDs (r =0.88, P<0.0001). CONCLUSIONS: In lung cancer patients with COPD, the 1-month Δ6MD was strongly associated with both the 3-month Δ6MD and the 6-month Δ6MD. These findings suggest that the decrease in exercise tolerance of patients whose 6MD is low at 1 month postoperatively may be prolonged, and such patients may therefore be in greater need of postoperative outpatient rehabilitation.

Chemical Senses Affecting Cough and Swallowing.

BACKGROUND: Dysfunction of swallowing and coughing leads to life-threatening aspiration pneumonia, especially in the elderly. In order to induce the cough and swallowing reflexes efficiently, sensory inputs to trigger the reflexes are essential. METHODS: Both the cough and swallowing reflexes respond to mechanical and chemical stimuli. However, the mechanisms of action of the two reflexes are not homogeneous. Some substances stimulate both reflexes, but others stimulate one of the reflexes and inhibit the other one. RESULTS: Capsaicin, a TRPV1 agonist, stimulates both the cough and swallowing reflexes. Menthol, a TRPM8 agonist, stimulates the swallowing reflex, but it inhibits the cough reflex, especially if applied to the nose. Acid stimulates the cough reflex but its effect on the swallowing reflex is complicated. Theophylline inhibits the cough reflex by decreasing the excitability of sensory nerves, whereas it stimulates the swallowing reflex by antagonizing adenosine receptors. In smoking, cigarette smoke and nicotine have different effects. Cigarette smoke stimulates the cough reflex, while it inhibits the swallowing reflex. Nicotine inhibits the cough reflex but does not affect the swallowing reflex. CONCLUSION: Whenever you prescribe for an abnormality of one of the reflexes, you should think about the effect of the prescription on the other reflex.

Low level laser therapy (lllt) for chronic joint pain of the elbow, wrist and fingers.

BACKGROUND AND AIMS: In previous studies, we successfully applied Low Level Laser Therapy (LLLT) in patients with non-specific chronic pain of the shoulder joint and lower back. The purpose of the present study was to assess the effectiveness of LLLT for chronic joint pain of the elbow, wrist, and fingers. SUBJECTS AND METHODS: Nine male and 15 female patients with chronic joint pain of the elbow, wrist, or fingers, who were treated at the rehabilitation outpatient clinic at our hospital from April, 2007 to March, 2009 were enrolled in the study. We used a 1000 mW semiconductor laser device. Each tender point and three points around it were irradiated with laser energy. Each point was irradiated twice for 20 s per treatment, giving a total of three minutes for all 4 points. Patients visited the clinic twice a week, and were evaluated after four weeks of treatment. Pain was evaluated with a Visual Analogue Scale (VAS). Statistical analysis of the VAS scores after laser irradiation was performed with Wilcoxon's signed rank sum test, using SPSS Ver.17. RESULTS: All VAS scores were totaled and statistically analyzed. The average VAS score before irradiation was 59.2±12.9, and 33.1±12.2 after the irradiation, showing a significant improvement in VAS score (p<0.001) after treatment. The treatment effect lasted for about one and a half days in the case of wrist pain, epicondylitis lateralis (tennis elbow), and carpal tunnel syndrome. In other pain entities, it lasted for about three to fifteen hours. No change in the range of motion (ROM) was seen in any of the 24 subjects. CONCLUSION: We concluded that LLLT at the wavelength and parameters used in the present study was effective for chronic pain of the elbow, wrist, and fingers.

Low level laser therapy for patients with cervical disk hernia.

BACKGROUND AND AIMS: In previous studies we have reported the benefits of low level laser therapy (LLLT) for chronic shoulder joint pain, elbow, hand and finger pain, and low back pain. The present study is a report on the effects of LLLT for chronic neck pain. MATERIALS AND METHODS: Over a 3 year period, 26 rehabilitation department outpatients with chronic neck pain, diagnosed as being caused by cervical disk hernia, underwent treatment applied to the painful area with a 1000 mW semi-conductor laser device delivering at 830 nm in continuous wave, 20.1 J/cm(2)/point, and three shots were given per session (1 treatment) with twice a week for 4 weeks. RESULTS: 1. A visual analogue scale (VAS) was used to determine the effects of LLLT for chronic pain and after the end of the treatment regimen a significant improvement was observed (p<0.001). 2. After treatment, no significant differences in cervical spine range of motion were observed. 3. Discussions with the patients revealed that in order to receive continued benefits from treatment, it was important for them to be taught how to avoid postures that would cause them neck pain in everyday life. CONCLUSION: The present study demonstrates that LLLT was an effective form of treatment for neck and back pain caused by cervical disk hernia, reinforced by postural training.
