ABSTRACT
An emerging body of research utilizes music in the treatment of children with specific learning disorders in reading. However, greater understanding of music interventions is necessary for efficient application of music to address children's specific reading needs. Therefore, this scoping review aimed to identify the key musical concepts used to improve reading skills. Intervention studies were identified through online searches of databases and hand searching of primary journals in music therapy, and 12 studies met the inclusion criteria. For the 12 studies, auditory processing, phonological processing, and temporal processing were the underlying mechanisms identified in the interventions. Most of the interventions presented rhythmic activities for the purpose of improving reading accuracy. The results of this study highlight the lack of specific descriptions for the musical elements used within music interventions targeting reading skills. In addition, due to the diversity of the terms used to describe the music interventions, it was difficult to compare the effectiveness of these interventions on reading accuracy, comprehension skills, and fluency. Therefore, future studies are needed to articulate clear rationales for how musical elements can be used in music interventions to treat specific reading disabilities in children.
ABSTRACT
INTRODUCTION: Dementia affects the quality of life. Excessive noise in care environments can exacerbate stress and related symptoms. Headphone-based music interventions may help improve the quality of life for people with dementia in long-term care homes. This review aims to explore and synthesise research on headphone-based music interventions for people with dementia in long-term care homes, focusing on enablers and barriers to implementing headphone-based music interventions. METHODS AND ANALYSIS: Joanna Briggs Institute guidance for scoping review and Preferred Reporting Items for Scoping Reviews and Meta-analyses extension for Scoping Reviews will guide the review and report process. CINAHL, MEDLINE, Embase, Web of Science, Scopus, AgeLine, PsycINFO and ProQuest databases will be searched for relevant literature from June 2010 to January 2024, supplemented by hand searches and Google for grey literature. Two research assistants will independently screen citations, followed by a full-text review. Data will be extracted using a data extraction tool. We will present the data in a table with narratives that answer the questions of the scoping review. ETHICS AND DISSEMINATION: This scoping review does not require ethics approval and participation consent, as all data will be publicly available. The scoping review results will be disseminated through conference presentations and an open-access publication in a peer-reviewed journal. The findings will provide practical insights into the adoption and efficacy of headphone-based music programmes for dementia in long-term care homes, contributing to education, practice, policy and future research.

Background: With longer life spans and medical advancements, the rising number of patients with advanced-stage Parkinson's disease (PD) warrants attention. Current literature predominantly addresses dementia and fall management in these patients. However, exploring the impact of swallowing function on patients with advanced PD is crucial. Previous research has demonstrated notable enhancements in the quality of life related to voice for participants following a group singing-intervention program. To further elucidate the effect of individual singing-induced swallowing exercises, our study aimed to investigate the quantitative and qualitative effects of therapeutic singing on swallowing function in patients with advanced PD in comparison to a matched usual care control group. The hypothesis of this study is that therapeutic singing-induced swallowing exercises can assist to maintain swallowing function in patients with advanced PD. Methods: This prospective matched control study compared the effects of a 6-week therapeutic singing-based swallowing intervention on swallowing function and quality of life in patients with advanced PD. The intervention group received individual sessions with a music therapist and conventional individual physical therapy. The control group received the same standard physical therapy for 6 weeks without music intervention. The primary outcome measure was Video Fluoroscopic Dysphagia Scale (VDS). Results: The study revealed that the intervention group maintained swallowing function, whereas the control group experienced deterioration, indicating significant time-dependent changes in Penetration-Aspiration Scale (PAS), National Institutes of Health-Swallowing Safety Scale (NIH-SSS), and VDS. Analysis of PAS and NIH-SSS liquid food scores in both groups showed significant time effects. However, the intervention group exhibited no significant differences between the pre- and post-tests, indicating preservation of the swallowing function. VDS of liquid food indicated an interaction effect between time and group in the pharyngeal phase and total scores. The Swallowing-Quality of Life showed significant time-effect improvement in the intervention group. Conclusion: Therapeutic singing exercises may help maintain swallowing function in advanced PD patients, potentially enhancing quality of life related to swallowing in those with advanced-stage diseases.

ABSTRACT
Active biological molecules present a powerful, yet largely untapped, opportunity to impart autonomous regulation to materials. Because these systems can function robustly to regulate when and where chemical reactions occur, they have the ability to bring complex, life-like behavior to synthetic materials. Here, we achieve this design feat by using functionalized circadian clock proteins, KaiB and KaiC, to engineer time-dependent crosslinking of colloids. The resulting material self-assembles with programmable kinetics, producing macroscopic changes in material properties, via molecular assembly of KaiB-KaiC complexes. We show that colloid crosslinking depends strictly on the phosphorylation state of KaiC, with kinetics that are synced with KaiB-KaiC complexing. Our microscopic image analyses and computational models indicate that the stability of colloidal super-structures depends sensitively on the number of Kai complexes per colloid connection. Consistent with our model predictions, a high concentration stabilizes the material against dissolution after a robust self-assembly phase, while a low concentration allows circadian oscillation of material structure. This work introduces the concept of harnessing biological timers to control synthetic materials; and, more generally, opens the door to using protein-based reaction networks to endow synthetic systems with life-like functional properties.
ABSTRACT
Objectives: Presbyphagia refers to age-related changes in the swallowing mechanism (e.g., reduced skeletal muscle strength that decreases bolus control). If left untreated, these changes can lead to dysphagia, which refers to impaired swallowing (e.g., coughing or choking when eating). Given that swallowing difficulties are common among older adults that they make up the fastest growing age group globally, the need for interventions to address presbyphagia is gaining urgency. To begin to address this need, we conducted a scoping review to analyze music therapy research aimed at enhancing swallowing function. The objective was to identify key intervention characteristics and propose clinical implications for treating presbyphagia using music therapy. Methods: This review followed the methodological frameworks outlined by Arksey and O'Malley and Levac et al. and used the Preferred Reporting Items for Systematic Reviews and Meta-Analysis for Scoping Reviews for analysis and reporting. Four electronic databases (i.e., ProQuest, PubMed, RISS, Web of Science) were searched for quantitative and qualitative studies in English or Korean that used music-based interventions to address swallowing function in older adults. Content analysis was conducted to identify and compare the main features of music interventions for swallowing difficulties among older adults. Results: Ten articles were identified and analyzed. It was found that three core components-respiration, vocalization, and singing-were employed to enhance swallowing function in populations with neurological impairments, dementia, or head and neck cancer. Notably, actions closely linked to swallowing function, such as laryngeal elevation and oral movements, were utilized therapeutically to speak or sing. Based on these characteristics, clinical implications are proposed to address presbyphagia. Conclusion: Singing entails a systematic and focused incorporation of stepwise activities that can be used to address swallowing disorders. In this context, critical clinical implications that music therapists should consider when treating individuals with presbyphagia include warmup breathing, vocalizing targeting laryngeal control, and singing targeting oral motor control. This review can contribute to the expansion of music therapy with older adults and the advancement of music therapy techniques.
ABSTRACT
Objective: This descriptive study surveyed family caregivers of patients in intensive care units (ICUs) during the COVID-19 pandemic to examine the impact of musical listening on their psychological well-being. Method: The data collected in this study compared with collected from similar research conducted before the COVID-19 pandemic in 2017. The previous study had 195 participants, and the current study had 92. To measure the participants' psychological well-being, the Korean version of the Center for Epidemiologic Studies Depression Scale and the World Health Organization Quality of Life Scale were administered. An investigator-constructed questionnaire was also used to collect information related to participants' engagement in music activities including music listening in their everyday lives and their perceptions of music's benefits. Results: A two-way ANOVA showed significant effects for time (e.g., before vs. during COVID-19) and involvement in personal music listening (yes vs. no) on current emotional state, with family caregivers reporting significantly greater negative emotions during COVID-19 than before and personal music listening having a positive effect on perceived emotions. For quality of life there was no significant time effect, while the listening effect was statistically significant, indicating a significantly higher quality of life in the group who engaged in music listening in their everyday lives compared to the group who did not. There were no significant time or listening effects for perceived level of depression. Conclusion: Given the COVID-19 situation and the need to transition to a post-pandemic era, this study suggests that music listening can be an effective option for family caregivers to implement as a resource for attenuating emotional distress and enhancing self-care.
ABSTRACT
The immunogenicity of a heterologous vaccination regimen consisting of ChAdOx1 nCoV-19 (a chimpanzee adenovirus-vectored vaccine) followed by mRNA-1273 (a lipid-nanoparticle-encapsulated mRNA-based vaccine) against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), specifically the omicron variant (B.1.1.529), is poorly studied. The aim of this study was to evaluate the neutralizing antibody activity and immunogenicity of heterologous ChAdOx1 nCoV-19 and mRNA-1273 prime-boost vaccination against wild-type (BetaCoV/Korea/KCDC03/2020), alpha, beta, gamma, delta, and omicron variants of SARS-CoV-2 in Korea. A 50% neutralizing dilution (ND50) titer was determined in serum samples using the plaque reduction neutralization test. Antibody titer decreased significantly at 3 months compared with that at 2 weeks after the 2nd dose. On comparing the ND50 titers for the above-mentioned variants of concerns, it was observed that the ND50 titer for the omicron variant was the lowest. This study provides insights into cross-vaccination effects and can be useful for further vaccination strategies in Korea.
ABSTRACT
(1) Background: Individuals with pulmonary disease need intensive and consistent rehabilitation due to their high risk for serious illness and long-term complications. The purpose of this scoping review was to provide a comprehensive analysis of relevant research regarding the use of singing in pulmonary rehabilitation. (2) Methods: A systematic literature search was performed using the PsycINFO, CINAHL, PubMed, and Web of Science databases. A search for studies that employed singing in pulmonary rehabilitation for patients with pulmonary disease was conducted. (3) Results: Studies that met the selection criteria were summarized and analyzed. Twenty-seven studies were included in the final analysis. Results showed that research using singing in pulmonary rehabilitation generally employed an intervention with structured tasks and additional home practice or socialization time. However, the singing procedure in each intervention was not always specifically described and the findings were inconsistent. (4) Conclusions: Programmed singing interventions can support lung health and be an effective component of pulmonary rehabilitation. The therapeutic singing method in relation to respiratory exercises should be integrated into the main activity in the intervention. Overall, singing has physical and psychosocial effects, leading to improvements in symptoms, but more research is necessary to ensure that the respiratory needs of people with pulmonary disease are adequately met.

Deficits in executive functioning are a common feature of Alzheimer's disease (AD) and result from impairment in the central executive system. As a result, elderly patients with early stage AD may require interventions that are more cognitively intense than traditional interventions. To address this need, in this multiple case study, we explored a dual-task-based music therapy intervention that involved drum playing and singing designed to induce attentional and motor controls. Three octogenarians diagnosed with early stage AD participated in 12 dual-task-based music therapy sessions over 6 weeks. Measures of executive functioning and the performance of a bimanual drum tapping task were evaluated before and after the intervention. Improvements in executive functioning were observed for participants A and C. After the intervention, reduced mean synchronization errors were found for the simultaneous tapping condition for all three participants. Although there was variability in the functional changes between participants, it is noteworthy that positive improvements in the elderly patients with early stage AD were obtained following dual-task-based music therapy. The results suggest that music therapy integrated into the dual-task paradigm can be an effective way to address degenerative cognitive deficits among elderly patients with early stage AD.

The cyanobacterial clock presents a unique opportunity to understand the biochemical basis of circadian rhythms. The core oscillator, composed of the KaiA, KaiB, and KaiC proteins, has been extensively studied, but a complete picture of its connection to the physiology of the cell is lacking. To identify previously unknown components of the clock, we used KaiB locked in its active fold as bait in an immunoprecipitation/mass spectrometry approach. We found that the most abundant interactor, other than KaiC, was a putative diguanylate cyclase protein predicted to contain multiple Per-Arnt-Sim (PAS) domains, which we propose to name KidA. Here we show that KidA directly binds to the fold-switched active form of KaiB through its N-terminal PAS domains. We found that KidA shortens the period of the circadian clock both in vivo and in vitro and alters the ability of the clock to entrain to light-dark cycles. The dose-dependent effect of KidA on the clock period could be quantitatively recapitulated by a mathematical model in which KidA stabilizes the fold-switched form of KaiB, favoring rebinding to KaiC. Put together, our results show that the period and amplitude of the clock can be modulated by regulating the access of KaiB to the fold-switched form.

Background: Patients with acquired brain injury (ABI) suffer from deficits in fine motor function in hands which affect independent self-care function in daily life. This study aimed to examine the effects of movement-specific keyboard playing for improved hand function in adolescents and young adults with ABI. Method: A total of 23 patients with ABI participated in this study. Twelve were assigned to the intervention group and eleven to the control group. The intervention group engaged in movement-specific keyboard playing three to four times a week for 3 weeks in addition to standard care, while the control group received only standard care. Results: The results of a mixed model of repeated measures ANOVA showed that the time effects were significant in the functional independence measure, key-pressing force, and most of the hand function tests measured. In terms of the interaction effect between group and time, a significant effect was found only in the checker-stacking task as a subtest of the Jebsen-Talyor Hand Function Test. Discussion: These results indicate that the specified movements required to play the keyboard may involve more precise and dexterous manipulation with hands and fingers. These results also suggest that movement-specific keyboard playing has potential in optimizing the intervention effect of keyboard playing while maximizing the benefits of music for motivating young patients with ABI.
ABSTRACT
BACKGROUND: Head and neck cancer patients often suffer from dysphagia after surgery and radiotherapy. A singing-enhanced swallowing protocol was established to improve their swallowing function. This study aimed to evaluate the beneficial effects of therapeutic singing on dysphagia in head and neck cancer (HNC) patients. METHODS: Patients who participated in this study were allocated to the intervention group (15 patients) and the control group (13 patients). Patients assigned to the intervention group received therapeutic singing 3 times per week for 4 weeks. Each group was divided into 2 subgroups, including the oral cavity cancer group and the pharyngeal cancer group. The patients' vocal functions were evaluated in maximum phonation time, pitch, intensity, jitter, shimmer, harmonics to noise ratio, and laryngeal diadochokinesis (L-DDK). To evaluate swallowing function, videofluoroscopic swallowing study was done, and the results were analyzed by videofluoroscopic dysphagia scale (VDS) and dynamic imaging grade of swallowing toxicity (DIGEST). RESULTS: Among the voice parameters, L-DDK of the intervention group significantly increased compared to that of the control group. Swallowing functions of the intervention group were significantly improved in VDS and DIGEST after the intervention. Detailed items of VDS and DIGEST showed improvements especially in the pharyngeal phase score of VDS, such as laryngeal elevation, pharyngeal transit time, and aspiration. In addition, the pharyngeal cancer group showed significant improvements in VDS and DIGEST scores after the intervention. CONCLUSIONS: Our outcomes highlight the beneficial effects of singing for HNC patients with dysphagia. The notable improvements in the pharyngeal phase suggest that therapeutic singing would be more appropriate for HNC patients who need to improve their intrinsic muscle movements of vocal fold and laryngeal elevation.

Although there have been increasing reports regarding the effectiveness of dual-task interventions in rehabilitation, the scope of this research is limited to gross motor movement, such as gait among patients with Parkinson's disease (PD). To expand the dual-task paradigm to upper extremity motor and attention control in PD, drum playing with modulation of musical elements was attempted. The objective of this study was to evaluate the effects of a drum playing intervention with rhythmic cueing on upper extremity motor control and attention control in patients with PD. Twelve participants were randomly assigned to the drum playing intervention with rhythmic cueing group or the control group. The results showed that the drum playing with rhythmic cueing (DPRC) group significantly increased their sustained time of entrainment (45 BPM) and their latency time until entrainment from pretest to posttest. For the DPRC group, the latency time until entrainment was significantly improved, and improvements in cognitive measures were also found. This study shows that DPRC has great potential to improve upper extremity motor control and attention control and supports the development of new interventions that include this technique for rehabilitation in patients with PD.

Swallowing difficulties are a common complaint among patients with a variety of diseases. To address these concerns, a singing-enhanced swallowing protocol was constructed, and its differential benefits for two patient populations were investigated. Two patients with Parkinson's disease (PD) and two patients with head and neck cancer (HNC) participated in this study. Each patient participated in 30-min individual sessions of a singing-enhanced swallowing protocol two times per week for 12 weeks. Following the intervention, laryngeal diadochokinesis and quality-of-life measurements were found to be higher in all four patients. However, the Videofluoroscopic Dysphagia Scale showed this improvement was associated with different swallowing tasks for each patient group. In addition, the maximum phonation time decreased for patients with HNC, while it increased for patients with PD. The findings support the use of a singing-enhanced swallowing protocol for patients whose swallowing difficulties are due to neurological or structural impairment. In addition, the study results suggest that different intervention components should be considered depending on the etiology of the patient's swallowing difficulties.
ABSTRACT
PURPOSE: This study aimed to investigate the effects of patient-directed interactive music on saliva melatonin levels and sleep quality among postoperative elderly patients in the intensive care unit (ICU). PATIENTS AND METHODS: A total of 133 elderly patients were randomized into three groups: interactive music therapy (IMT), passive listening (PL), and the control group. The control group (n = 45) received routine medical care, while IMT and PL groups received music therapy on ICU day 1. The IMT group received up to 20 mins of interactive music sessions, including relaxation techniques. The PL group received only pre-selected relaxing music-listening for 30 mins. Saliva melatonin and cortisol levels were measured three times at 11 p.m. (preoperative, operation day, and postoperative day [POD] 1). The Richards-Campbell Sleep Questionnaire (RCSQ) and Quality of Recovery-40 questionnaire (QoR40) were administered on the preoperative day, as well as PODs 1 and 2. RESULTS: The RCSQ showed a significant improvement in the IMT group compared to the control group on POD2 (71.50 vs 56.89, p=0.012), but the QoR40 did not show any difference between groups. The quality control of the saliva sample was not available due to the immediate postoperative patient's condition, resulting in a higher dropout rate. Saliva melatonin levels on POD 1 were elevated in the IMT group compared to the control group (1.45 vs 0.04, p=0.0068). The cortisol level did not show a significant difference between groups. CONCLUSION: Single IMT intervention improved subjectively assessed short-term sleep quality in postoperative elderly patients. It is difficult to conclude whether music therapy intervention affects the level of melatonin and cortisol. TRIAL REGISTRATION: The study was registered at ClinicalTrials.Gov (number NCT03156205).
ABSTRACT
This study aimed to investigate the differences in gait outcomes of young adults with cerebral palsy (CP) following rhythmic auditory stimulation (RAS) with different types of cueing. A total of 13 ambulatory adults with CP were recruited. The participants were assigned to receive either RAS with simple chords or RAS with complex chords. Each participant received 30-min individual sessions three times per week for 4 weeks. In the simple RAS group, basic chords were used for cueing. In the complex RAS group, the diversified chords were adopted from patients' preferred music. At pre- and posttest, spatiotemporal and kinematic parameters and the range of motion (ROM) for each joint during a gait cycle were collected. After RAS, cadence, velocity, and stride length significantly increased, but no significant group effect was found. Meanwhile, regarding kinematic parameters, a significant interaction effect between time and group was observed with the angle of plantar flexion in the preswing phase and ROM in the ankle. The complex RAS group showed increased maximal ankle plantar flexion in the preswing phase. These results demonstrated that the primary agent for gait control is rhythm, while perception of music facilitates patient engagement in walking differently depending on the level of musical elements.

Human CD141+ dendritic cells (DCs), specialized for cross-presentation, have been extensively studied in the development of DC-based therapy against cancer. A series of attempts was made to generate CD141+ DCs from cord blood CD34+ hematopoietic progenitors to overcome the practical limitation of in vivo rareness. In the present study, we identified a culture system that generates high CD141+ DCs. After culture of CD14+ monocytes in the presence of granulocyte macrophage colony-stimulating factor (GM-CSF) and interleukin (IL)-4 for 8 days, CD141 was detected on cells that adhered to the bottom of the culture plate. The attached cells exhibited typical features of immature monocyte-derived DCs (moDCs), except for higher CD86 expression, more dendrites and higher granularity compared with those that did not attach. With 3 additional days of culture, increased CD141 expression on the cells was retained along with adhesion ability and partial expression of CLEC9A, a c-type lectin receptor. Furthermore, the cells exhibited effective uptake of dead cells. Interestingly, the attached moDCs differently responded to polyinosinic:polycytidylic acid (poly I:C) stimulation as well as a mixed lymphocyte reaction. Collectively, our findings show that human CD141+ DCs can be sufficiently generated from peripheral blood CD14+ monocytes, potentiating further investigation into generation of higher yields of cross-priming human DCs in vitro.

The aim of this meta-analysis was to review studies that applied musical instrument playing as an intervention to improve cognitive functioning of older adults with and without cognitive impairment. English-language articles published between 1990 and 2018 were searched using electronic databases. Music therapy journals were also hand searched for relevant research. Inclusion criteria for participants were older adults, ages 60 years and older, and any clinical diagnosis of cognitive impairment had to be due to aging. Searches used combinations of the following keywords: older adults, instrument playing, and cognitive outcomes measures. A total of 10 studies that met the inclusion criteria were included in the final analysis: five studies with healthy older adults, two with older adults with mild cognitive impairment (MCI), two studies with older adults with dementia, and one study with both healthy older adults and older adults with MCI. The results of this meta-analysis demonstrated that different types of cognitive involvement were demanded from instrument playing. Furthermore, depending on the type of involvement, a target cognitive domain was found to be differentially impacted by the instrument playing intervention. This study supports using different types of instrument playing for interventions targeting specific cognitive domains of older adults with varying levels of cognitive aging.
ABSTRACT
Perilla oil has been shown to be beneficial for ameliorating metabolic disorders, but its protective effect is still controversial. We investigated the effect of perilla oil on obesity-induced hepatic and vascular changes in high-fat diet (HFD)-fed mice and provided underlying mechanisms for potential therapeutic applications. Tomato and paprika extract was added to prevent the oxidation during storage of perilla oil. HFD-fed mice were orally administered palm or perilla oil for 90 days. Food intake, body and liver weight, and serum cholesterol levels were measured. Arterial and hepatic lipid accumulation was determined by histological staining. Hepatic triglyceride levels and the expression of proteins regulating lipid metabolism were analyzed. Food intake and body weight were not different between palm oil-treated and perilla oil-treated mice. Serum cholesterol level was significantly lower in perilla oil-treated mice compared with palm oil-treated mice. HFD-induced lipid accumulation was also lower in thoracic aorta and liver by perilla oil compared with palm oil. Perilla oil also decreased hepatic triglyceride level without changing the liver weight. Perilla oil treatment increased the AMP-activated protein kinase and acetyl-CoA carboxylase phosphorylation and the lipolytic protein levels, whereas it decreased the lipogenic protein levels in the liver. In conclusion, perilla oil reduced serum cholesterol and arterial and hepatic lipid accumulation in HFD-fed mice. The data suggest that perilla oil improves the balance of lipogenic and lipolytic protein expression, and ameliorates obesity-induced metabolic disorders and cardiovascular diseases.

This study aimed to investigate the effects of a rhythm-motor dual task intervention on cognitive and gait control for older adults in relation to fall prevention. Ten healthy older adults participated in a rhythm-motor dual task intervention and 10 participated in the control group. The intervention group received 16 30-min intervention sessions for 8 weeks. During the intervention sessions, participants engaged in walking or bimanual tapping as a primary motor task with concurrent rhythm tasks including playing instruments and rhythmic chanting or singing. At pretest and post-test, measures of cognition, balance/mobility, and gait were administered. A significant difference between groups was found for part B of the Trail Making Test (TMT-B) measure that involved executive control of attention. Also, changes in the gait ratio in the dual task condition of walking while playing an instrument were significantly different between groups. The findings in this study support the use of the rhythm-motor dual task intervention for increasing available cognitive resources and improving gait control, which are critical factors in fall prevention.
