Role of O-C2 angle in the development of dysphagia in patients with halo-vest fixation.

BACKGROUND: Dysphagia is one of the most serious complications in patients treated with a halo-vest brace. However, the cause of dysphagia development by halo-vest fixation is not yet clear. We therefore investigated the incidence of dysphagia and cervical alignment as well as clinical data from medical charts in patients treated with a halo-vest brace. METHODS: We retrospectively reviewed clinical data from the medical charts of 49 patients who had undergone halo-vest fixation. Occipito (O)-C2 angle, C2-C6 angle, and pharyngeal inlet angle were assessed by lateral plain X-rays of the cervical spine. The impacts of these parameters on incidence and severity of dysphagia were analyzed. RESULTS: Thirteen patients (32%) suffered from dysphagia during halo-vest fixation, and age and length of intensive care unit (ICU) stay were greater in the dysphagia group (p = 0.044 and 0.013, respectively) than in those who did not develop dysphagia. O-C2 angle was smaller in the dysphagia group (p = 0.016). After multivariate logistic analysis, body mass index, ICU stay, and O-C2 angle remained as independent risk factors related to incidence of dysphagia. Spearman rank correlation showed a negative correlation between ICU stay and Food Intake Level Scale (FILS) (p = 0.026), and a positive correlation between O-C2 angle and FILS (p = 0.008). CONCLUSION: This study suggested that O-C2 angle is related to both incidence and severity of dysphagia due to halo-vest fixation.

Comprehensive Geriatric Assessment in the era of telemedicine.

The aging global population poses significant medical and social challenges, necessitating efforts to promote healthy aging. Comprehensive Geriatric Assessment (CGA) is a multidimensional diagnostic approach for older adults that aims to improve overall health. Remote CGA, facilitated by technological advancements, offers convenience and other potential advantages. It enables early disease detection, monitors chronic disease progression, delivers personalized care, and optimizes healthcare resources for better health outcomes in older individuals. However, remote CGA also has limitations, including technological requirements, data security, and the need for comprehensive evaluation and simplicity. Collaborative efforts are essential to developing a digital home-based CGA platform that addresses accessibility issues and tailors the assessment process to meet the needs of older adults. Continuous optimization of remote CGA can become a pivotal tool for advancing geriatric care and ensuring the well-being of the aging population. Geriatr Gerontol Int 2024; 24: 67-73.

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.

Geriatric Nutritional Risk Index Predicts High Activities of Daily Living at Discharge in Older Patients with Heart Failure after Cardiac Rehabilitation.

BACKGROUND: Hospitalization often leads to a decline in activities of daily living (ADL) in older patients with heart failure. Although cardiac rehabilitation (CR) improves ADL, it can be difficult to perform CR due to the deconditioning of these patients. This study aimed to examine the factors associated with ADL at discharge in older patients with heart failure who underwent CR. METHODS: A total of 86 of 110 older heart failure patients aged ≥ 75 years (average age, 86.9 ± 5.7 years) transferred to our institution for CR were enrolled and classified into high ADL at discharge (n = 54) and low ADL at discharge (n = 32) groups. Physical characteristics, comorbidities, medications, blood test data, echocardiographic data, and nutritional status (Geriatric Nutritional Risk Index [GNRI]) were retrospectively examined from medical records. ADL were assessed using the Barthel Index (BI) at admission and discharge. Considering multicollinearity, the relationship between high ADL (BI ≥ 60) at discharge and these assessments at admission was analyzed using multiple logistic regression analysis. The receiver operating characteristic curve was analyzed to calculate the cutoff values for the parameters identified by the multiple logistic regression analysis. RESULTS: The GNRI was the only independent factor predicting high ADL at discharge (p = 0.041; odds ratio [OR], 1.125; 95% confidence interval [CI], 1.005-1.260). The area under the receiver operating characteristic curve for the GNRI was 0.770 (95% CI, 0.664-0.876). The cutoff value for the GNRI was 83.4 (sensitivity, 85.2%; specificity, 62.5%). CONCLUSION: These findings suggest that the GNRI score at admission predicts high ADL at discharge in older patients with heart failure who underwent CR.

Improving taste sensitivity in healthy adults using taste recall training: a randomized controlled trial.

Although many patients suffer from taste disorder, methods to improve taste sensitivity are limited. To develop a taste recall training method to improve the perception of taste, 42 healthy individuals were randomly assigned to either the training or the control group. Using the filter paper disc method, participants in the training group were asked to match the four tastes (sweetness, saltiness, sourness, and bitterness) between those of taste recognition thresholds and those of a one-step higher concentration until they get them right. Then, they were asked to match the four tastes between those of one-step lower and one-step higher in concentration from their taste recognition thresholds until they get them right. Finally, they were asked to match the four tastes between those of one-step lower concentration and those of their taste recognition thresholds until they get them right. This training was repeated until perfectly matched. The taste recall training program led to a lowered taste recognition threshold in healthy adults for each taste quality, suggesting the improvement of taste sensitivity. This lowered threshold for each taste was observed with each additional training session. We conclude that this taste recall training method might be a therapeutic approach for treating taste disorder.

Determinants of Six-Minute Walk Distance in Idiopathic Pulmonary Fibrosis and Idiopathic Pleuroparenchymal Fibroelastosis.

Background: In idiopathic pulmonary fibrosis (IPF), 6-minute walking distance (6MWD) is an independent factor for mortality. Idiopathic pleuroparenchymal fibroelastosis (IPPFE) is a rare disease with physical features such as emaciation, but the relationship between IPPFE and 6MWD is unclear. In this study, we investigated the factors that cause a decrease in the percent of the predicted value of a 6-minute walk distance (%6MWD), including the disease entities, IPF and IPPFE. Methods: This study included 100 patients (IPF: 75 patients, IPPFE: 25 patients, age: 73.5 ± 7.2 years, sex: 73 males) who visited the rehabilitation department. Patients with a %6MWD ≥ 80% were assigned to the normal group (n = 54), and patients with a %6MWD < 80% were assigned to the decreased group (n = 46). The items showing a significant difference between groups were used as independent variables, after the consideration of multicollinearity, for a logistic analysis where %6MWD < 80% was used as the dependent variable. Results: The 6MWD results show that there was no significant difference between IPF and IPPFE in the absolute value of 6MWD and in the number of people with 6MWD ≥ 250 m, but when 6MWD was compared with %6MWD, the IPPFE group showed a significantly lower value than the IPF group (p = 0.013). Logistic regression analysis showed that only BMI (p = 0.032), GAP index (p = 0.043), and mMRC (p = 0.026) were factors that caused a decrease in %6MWD in 100 patients. Conclusion: The results suggest that leanness, shortness of breath and severity of illness are the most important factors that determine exercise tolerance, regardless of disease entity in IPF and IPPFE.

Benefits of Pulmonary Rehabilitation in Patients with Idiopathic Pulmonary Fibrosis Receiving Antifibrotic Drug Treatment.

Background: Although patients with idiopathic pulmonary fibrosis (IPF) often receive treatment with antifibrotic drugs (AFDs) and pulmonary rehabilitation (PR) concurrently, there are no reports on the effect of PR on patients with IPF receiving AFDs. Therefore, we investigated the effect of PR on patients with IPF receiving AFDs. Methods: Eighty-seven eligible patients with IPF (61 male; 72.0 ± 8.1 years; GAP severity stage I/II/III: 26/32/12) were recruited for the study. Patients who completed a 3-month outpatient PR program and those who did not participate were classified into four groups according to use of AFDs: PR group (n = 29), PR+AFD group (n = 11), treatment-free observational group (control group; n = 26), and AFD group (n = 21). There was no significant difference in age, sex, or severity among the groups. Patients were evaluated for physical functions such as 6-min walk distance (6MWD) and muscle strength, dyspnea, and health-related quality of life (HRQOL) at baseline and at 3 months. Results: In the PR group, dyspnea and 6MWD showed significant improvement after the 3-month PR program (p < 0.05 and p < 0.01, respectively). HRQOL was significantly worse at 3 months (p < 0.05) in the AFD group, but not in the other groups. The change in 6MWD from baseline to the 3-month time point was significantly higher in the PR+AFD group than in the AFD groups (p < 0.01). Conclusions: It was suggested that AFD treatment reduced exercise tolerance and HRQOL at 3 months; however, the concurrent use of PR may prevent or mitigate these effects.

Role of preoperative cervical alignment on postoperative dysphagia after occipitocervical fusion.

BACKGROUND: Dysphagia is one of the most serious complications of occipitocervical fusion (OCF). The previous studies have shown that postoperative cervical alignment, documented with occipito (O)-C2 angles, C2-C6 angles, and pharyngeal inlet angles (PIA), impacted the incidence of postoperative dysphagia in patients undergoing OCF. Here, we investigated the relationship of preoperative versus postoperative cervical alignment on the incidence of postoperative dysphagia after OCF. METHODS: We retrospectively reviewed the clinical data/medical charts for 22 patients following OCF (2006- 2019). The O-C2 angles, C2-C6 angles, PIA, and narrowest pharyngeal airway spaces (nPAS) were assessed using plain lateral radiographs of the cervical spine before and after the surgery. The severity of dysphagia was assessed with the functional oral intake scale (FOIS) levels as documented in medical charts; based on this, patients were classified into the nondysphagia (FOIS: 7) versus dysphagia (FOIS: 1-6) groups. RESULTS: Seven patients (35%) experienced dysphagia after OCF surgery. Preoperative PIA and nPAS were smaller in the dysphagia group. Spearman rank correlation showed a positive correlation between preoperative PIA and FOIS and between preoperative nPAS and FOIS. CONCLUSION: This study suggests that preoperative cervical alignment may best predict the incidence of postoperative dysphagia after OCF.

Role of physical therapists and aromatherapy for fall prevention in older people: A narrative review.

Falls among older people are usually the result of several causes combined. Identifying all the fall-related factors that apply to a particular individual and providing comprehensive multifactorial intervention is recommended for the prevention of falls among older people. However, the overall net benefit of multifactorial intervention in preventing falls is small, and it does not appear to improve fall-related outcomes, such as the number of fall-related injuries. Therefore, we might require new perspectives to overcome this situation. Here, we raise two novel strategies for fall prevention among older people. One is using physical therapists more actively. The other is using aromatherapy for stabilization of older people. Physical therapists should carry out detailed gait assessment and caregiver education. Aromatherapy is effective in improving balance and mental stability in older people. To overcome refractory geriatric syndrome, there is no choice but to eliminate all preconceived ideas before choosing the best fall prevention strategies. Geriatr Gerontol Int 2021; 21: 445-450.

The effect of low level laser therapy for pain in major muscles controlling two joints.

BACKGROUND AND AIMS: Chronic pain is a significant health care problem which is often encountered in medical institute out-patient clinics . In previous studies we have reported on the benefits of low level laser therapy (LLLT) for chronic musculoskeletal pain patients. The present study is a report on the effects of LLLT in patients with pain in major muscles which govern the motion of two joints (2-joint muscles). MATERIALS AND METHODS: Over the past 5 years, 19 subjects visited our out-patient clinic with complaints of pain in 2-joint muscles (biceps brachii muscle or gastrocnemius muscle). They were treated with LLLT using a 1000 mW semi-conductor laser device delivering 20.1 J/cm2 per point at 830 nm in continuous wave. Four shots were given per session (1 treatment) twice a week for 2 months (total of 16 treatments). RESULTS: A treatment approach modified from the methods of Shiroto and Ohshiro, was used, and the efficacy of LLLT for pain attenuation in the affected muscle was determined. After the end of the treatment regimen, excellent and good improvement was observed in 16 patients out of 19. Discussions with the patients revealed that it was important for them to learn how to modify their everyday life to avoid posture and activities of daily life that could cause them pain in the 2-joint muscles, in order to enjoy continuous benefits from the treatment. CONCLUSION: The present study demonstrated that LLLT was an effective form of treatment for pain in the biceps brachii and gastrocnemius muscles. To maximize and prolong treatment efficacy, advice should be given to patients to avoid adopting any posture and activities of daily living which would cause pain in these specific muscles.

Low Level Laser Therapy for Radial Nerve Palsy Patients : Our Experience.

BACKGROUND AND AIMS: Peripheral nerve injury is one of the frequent complaints which is seen in the outpatient clinic of our medical institute. In previous studies we have reported on the benefits of low level laser therapy (LLLT) for central nerve system disorders, namely cerebrovascular accidents and cerebral palsy. The present study is a report on our experience of the effects of LLLT for peripheral nerve palsy. MATERIALS AND METHODS: Over the past 5 years, 13 subjects visited the out-patient clinic with the chief complaint of radial nerve palsy caused by compression of the nerve through with abnormal positioning, and sleeping posture at night. The patients were treated with LLLT. A 1000 mW semi-conductor laser device was used, delivering 830 nm in continuous wave at a dose of 20.1 J/cm2 /point, and five points were treated per session (i.e., 1 treatment) twice a week for 3 months (total 24 treatments). In 6 patients LLLT was combined with brace therapy. RESULTS: Modified Daniels' manual muscle testing was used to determine the effects of LLLT for the muscle power of the extensor carpi radialis, and on completing the treatment regimen excellent improvement was observed in 9 cases out of 13. Combination treatment (laser therapy with bracing) resulted in 4 excellent cases out of 6 cases. Discussions with the patients clarified that it was important for them to learn how to avoid the particular posture that could cause them radial nerve palsy in daily life in order to have continuous benefits from the treatment. CONCLUSION: The present study demonstrated that LLLT was an effective form of treatment for radial nerve palsy. In addition, patients were advised to avoid any incorrect posture which might induce radial nerve palsy.

Low Level Laser Therapy in patients with chronic foot and ankle joint pain.

BACKGROUND AND AIMS: Chronic foot and ankle joint pain is one of the most frequent complaints which is regularly seen in the out-patient clinic of our medical institute. In previous studies we have reported on the benefits of low level laser therapy (LLLT) for chronic pain in the elbow, hand, finger and the lower back. The present study examined the effects of LLLT on chronic foot and ankle joint pain. MATERIALS AND METHODS: Over the past 5 years, 17 subjects visited the out-patient clinic with complaints of chronic foot and ankle joint pain of a variety of aetiologies. The patients received LLLT using a 1000 mW semi-conductor laser device, delivering 20.1 J/cm2 per point at 830 nm in continuous wave. Each patient was given four shots per session per foot twice a week for 4 weeks. RESULTS: A visual analogue scale (VAS) was used to determine the effects of LLLT for the chronic pain and after the end of the treatment regimen a significant improvement was observed (p < 0.01). All but 2 of the patients showed improvement: excellent (2) and good (13). After treatment, no significant differences were observed in the ankle joint range of motion, however. Discussions with the patients revealed that it was important for them to learn how to avoid overuse of the ankle when walking, poor walking posture and a poor pacing technique that would caused them foot and ankle pain in everyday life. Following these postural guidelines could ensure continuous benefits from the treatment. CONCLUSION: The present study demonstrated that LLLT was an effective form of treatment for chronic foot and ankle joint pain, in conjunction with postural education during all activities of daily living.

Dysphagia, dystussia, and aspiration pneumonia in elderly people.

Despite the development and wide distribution of guidelines for pneumonia, death from pneumonia is increasing due to population aging. Conventionally, aspiration pneumonia was mainly thought to be one of the infectious diseases. However, we have proven that chronic repeated aspiration of a small amount of sterile material can cause the usual type of aspiration pneumonia in mouse lung. Moreover, chronic repeated aspiration of small amounts induced chronic inflammation in both frail elderly people and mouse lung. These observations suggest the need for a paradigm shift of the treatment for pneumonia in the elderly. Since aspiration pneumonia is fundamentally based on dysphagia, we should shift the therapy for aspiration pneumonia from pathogen-oriented therapy to function-oriented therapy. Function-oriented therapy in aspiration pneumonia means therapy focusing on slowing or reversing the functional decline that occurs as part of the aging process, such as "dementia → dysphagia → dystussia → atussia → silent aspiration". Atussia is ultimate dysfunction of cough physiology, and aspiration with atussia is called silent aspiration, which leads to the development of life-threatening aspiration pneumonia. Research pursuing effective strategies to restore function in the elderly is warranted in order to decrease pneumonia deaths in elderly people.

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.
