Safety and Tolerability of Strength Training in Spinal and Bulbar Muscular Atrophy: A Case Report

Objective: Spinal and bulbar muscular atrophy is characterized by slow-progressive muscle weakness, decreased functional performance and falls. Research into the use of exercise in spinal and bulbar muscular atrophy has shown equivocal to negative results, although authors suggest that patients with spinal and bulbar muscular atrophy may benefit from both increased exercise intensity and shorter bout duration. The aim of this case report is to explore the safety of a moderate-intensity strength training programme coupled with dynamic balance and function-specific training in a patient with spinal and bulbar muscular atrophy.Case report: A 56-year-old man with spinal and bulbar muscular atrophy presented with multiple falls and declining performance in physical, vocational, and recreational activities. Examination revealed several musculoskeletal impairments that were sub-clinical to mild compared with an SBMA natural history cohort.Intervention and outcome: A 15-week moderate-intensity exercise programme combining weightlifting and functional exercises was performed under clinical supervision. Exercise volume, frequency and intensity were adjusted based on patient-reported outcomes and muscle damage blood markers. Performance-based and selfreported functional improvements occurred that exceeded the minimal clinically important difference. The intervention was well tolerated and the patient nearly doubled his baseline 10-repetition maximums for weight-lifting exercises. Conclusion: Exercise therapy combining weightlifting and upright functional training led to meaningful performance improvements in this case of a patient with spinal and bulbar muscular atrophy and relatively low disease burden. LAY ABSTRACTSpinal and bulbar muscular atrophy (SBMA) is a rare neuromuscular disease characterized by slow-progressive muscle weakness, decreased functional performance, and falling. With limited research for guidance, medical practitioners often advise patients with SBMA to avoid weight lifting or intensive exercise. The patient was a high-functioning 56-year-old man with SBMA who struggled with performing daily activities and intensive physical work demands. He participated in a closely monitored 15-week exercise program that combined weight lifting and functional exercises. The patient safely tolerated the program, self-reported physical improvements, and nearly doubled the weight for lifting exercises. This case report highlights one individual with SBMA who benefitted from moderate-intensity exercise, including weight lifting, under careful clinical supervision. More research is needed before this intervention can be recommended for people with SBMA.

Validation of Body-Worn Sensors for Gait Analysis During a 2-min Walk Test in Children

Introduction

Instrumented gait mat systems have been regarded as one of the gold standard methods for measuring spatiotemporal gait parameters. However, their portable walkways confine walking to a restricted area and limit the number of gait cycles collected. Wearable inertial sensors are a potential alternative that allow more natural walking behavior and have fewer space restrictions. The objective of this pilot study was to establish the concurrent validity of body-worn sensors against the portable walkway system in older children.

Methods

Twenty-one participants (10 males) 7-17 years old performed 2-min walk tests at a self-selected and fast pace in a 25-m-long hallway, while wearing three inertial sensors. Data collection were synchronized between devices and the portions of the walk when subjects passed on the walkway were used to compare gait speed, stride length, gait cycle duration, cadence, and double support time. Regression models and Bland-Altman analysis were completed to determine agreement between systems for the selected gait parameters.

Results

Gait speed, cadence, gait cycle duration, and stride length as measured by inertial sensors demonstrated strong agreement overall. Double support time was found to have lower validity due to a combined bias of age, height, weight, and walking pace.

Conclusion

These results support the validity of wearable inertial sensors in measuring gait speed, cadence, gait cycle duration, and stride length in children 7 years old and above during a 2-min walking test. Future studies are warranted with a broader age range to thoroughly represent the pediatric population.

A Comparative Study of Social Impacts of the COVID-19 Pandemic on Republic of Korea, Japan, and Taiwan

OBJECTIVE

The frequency of various disasters has become a 21st century global crisis. The biological-disaster of the coronavirus disease of 2019 (COVID-19) gave rise to a multi-dimensional global impact. The 25 items of Societal Influences Survey Questionnaire (SISQ) was developed to assess various categories of social influence during the pandemic. This study compares the SISQ scores of Taiwan, Republic of Korea (Korea) and Japan.

METHODS

Persons living in Korea, Japan, and Taiwan were recruited and evaluated through an SISQ online survey. The SISQ is composed of 25 items each with a 4-point Likert scale. The SISQ assesses the following six factors: self-restraint, social impact, government policy, social cost, concern of infection, and awareness of information. A principal factor analysis and reliability (Cronbach's alpha) were performed to validate the SISQ. The analysis of variance (ANOVA) and post-hoc analysis was conducted to explore the differences between groups.

RESULTS

The SISQ had acceptable reliabilities, and accounted for 58.86% of the variance. The significance for ANOVA with post-hoc analysis showed that scores of self-restraints ranked highest in Japan followed by Taiwan and Korea. Taiwanese scored lower than other nations regarding the concern of infection. Koreans scored higher in awareness of information than the other two nations. The effect of age and marital status were also estimated.

CONCLUSION

The SISQ comprehensively evaluate multiple domains of social influence, and it manifests the divergence of social impacts across the three nations.

Development and validation of the Lo's Healthy and Happy Lifestyle Scale (LHHLS): The resilience in general population facing COVID-19 in Taiwan

BACKGROUND

This article explores the effectiveness of development of the Lo's Healthy and Happy Lifestyle Scale (LHHLS), which is an evaluative tool that monitors the resilience of the Taiwan population in times of such COVID-19 epidemic. Also, to verify factors of resilience, namely the reliability and validity of self-efficacy and positive thinking, and establishment of a prospective norm analysis.

METHOD

The study mainly applied Explorative Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) to develop LHHLS and establish the reliability and validity of the tool's structure, verify norm analysis and the reliability of data from each question using Cronbach's alpha.

RESULTS

According to statistics, LHHLS has a good factorial effectiveness and relatively high reliability, with factor reliability analyses where Cronbach's alpha lies between 0.83 to 0.94. The 14 questions in the LHHLS has a total variance of 67.04%. The tool includes two sub-assessments that are theoretically and statistically appropriate: mental health/self-efficacy and positive thinking.

CONCLUSION

The tool LHHLS can be applied to populations affected by COVID-19. With participants' self-awareness of mental health state and state of happy living, this tool is valid and reliable in assessing and evaluating the resilience of such participants against times of COVID-19. This study can become future use for epidemic prevention communities in monitoring residents' healthy living and changes in their resilience. Also, can become a reference standard for interventions to reduce the impacts populations' happy and healthy living, in times of biological disasters.

Exercise Intervention Leads to Functional Improvement in a Patient with Spinal and Bulbar Muscular Atrophy

Introduction

Spinal and bulbar muscular atrophy is a progressive neuromuscular disease that leads to muscle weakness and reduced physical function. Benefits of physical therapy for people with spinal and bulbar muscular atrophy have not been reported in the literature.

Case report

A 62-year-old male patient with spinal and bulbar muscular atrophy reported falling, difficulty walking and completing upright tasks, and showed clinical signs of low baseline function on examination. Transportation challenges made it difficult for this patient to attend frequent one-on-one physical therapy sessions.

Interventions and outcomes

A minimally supervised home-based exercise intervention was chosen with the goal of safely improving his functional capacity. The 5-visit clinical intervention, spread over 10 months, provided 3 exercise modules: seated-to-standing postural alignment and core muscle activation; upright functional and endurance training; and balance training and rhythmic walking. Post-intervention the patient had increased lower extremity muscle strength, improved balance, and reduced self-reported fatigue.

Conclusion

Home-based exercises were well tolerated with no increase in creatine kinase. Multiple clinical measures of strength and function improved, possibly related to the patients’ excellent motivation and compliance with the programme. Promising utilization of a minimally supervised home-based programme is described here.

Body-Worn Sensors Are a Valid Alternative to Forceplates for Measuring Balance in Children

Aims

Clinical evaluation of balance has relied on forceplate systems as the gold standard for postural sway measures. Recently, systems based on wireless inertial sensors have been explored, mostly in the adult population, as an alternative given their practicality and lower cost. Our goal was to validate body-worn sensors against forceplate balance measures in typically developing children during tests of quiet stance.

Methods

18 participants (8 males) 7 to 17 years old performed a quiet stance test standing on a forceplate while wearing 3 inertial sensors. Three 30-second trials were performed under 4 conditions: firm surface with eyes open and closed, and foam surface with eyes open and closed. Sway area, path length, and sway velocity were calculated.

Results

We found 20 significant and 8 non-significant correlations. Variables found to be significant were represented across all conditions, except for the foam eyes closed condition.

Conclusions

These results support the validity of wearable sensors in measuring postural sway in children. Inertial sensors may represent a viable alternative to the gold standard forceplate to test static balance in children.

Development and Implementation of Societal Influences Survey Questionnaire (SISQ) for Peoples during COVID-19 Pandemic: A Validity and Reliability Analysis

The emergence of Coronavirus disease 2019 (COVID-19) had rapidly spread since FEB/MAR 2020. Policy to prevent transmission of COVDI-19 resulted in multi-dimensional impact on social interaction. We aimed to develop a beneficial survey tool with favorable quality and availability, the Societal Influences Survey Questionnaire (SISQ), to evaluate social influences on people during this pandemic. The SISQ was developed with 15 items and 4-point Likert scales consisting of five factors. These include social distance, social anxiety, social desirability, social information, and social adaptation. Construct validity and reliability were performed to verify the SISQ. A total of 1912 Taiwanese were recruited. The results demonstrated that the SISQ has acceptable reliability, with Cronbach’s alphas ranging between 0.57 and 0.76. The SISQ accounted for 58.86% and satisfied the requirement of Kaiser–Mayer–Olkinvalues (0.78) and significant Bartlett’s Test of sphericity. Moreover, the confirmatory factor analysis fit indices also indicated the adequacy of the model. As for multiple comparison, females scored higher than males in factor of social distance. Unemployed participants and those without partners scored higher in several domains of factors. The survey method and survey instrument prove reliable and valuable, also providing different categories of assessment results regarding social influences and their impacts. Further studies are warranted to extend the applicability of SISQ.

Cryptic Species Account for the Seemingly Idiosyncratic Secondary Metabolism of Sarcophyton glaucum Specimens Collected in Palau

Sarcophyton glaucum is one of the most abundant and chemically studied soft corals with over 100 natural products reported in the literature, primarily cembrane diterpenoids. Yet, wide variation in the chemistry observed from S. glaucum over the past 50 years has led to its reputation as a capricious producer of bioactive metabolites. Recent molecular phylogenetic analysis revealed that S. glaucum is not a single species but a complex of at least seven genetically distinct species not distinguishable using traditional taxonomic criteria. We hypothesized that perceived intraspecific chemical variation observed in S. glaucum was actually due to differences between cryptic species (interspecific variation). To test this hypothesis, we collected Sarcophyton samples in Palau, performed molecular phylogenetic analysis, and prepared chemical profiles of sample extracts using gas chromatography-flame ionization detection. Both unsupervised (principal component analysis) and supervised (linear discriminant analysis) statistical analyses of these profiles revealed a strong relationship between cryptic species membership and chemical profiles. Liquid chromatography with tandem mass spectrometry-based analysis using feature-based molecular networking permitted identification of the chemical drivers of this difference between clades, including cembranoid diterpenes (2R,11R,12R)-isosarcophytoxide (5), (2S,11R,12R)-isosarcophytoxide (6), and isosarcophine (7). Our results suggest that early chemical studies of Sarcophyton may have unknowingly conflated different cryptic species of S. glaucum, leading to apparently idiosyncratic chemical variation.

Rate of psychiatric disorders and associations with quality of life among community members following the Kaohsiung gas explosion: an 18-month cross-sectional follow-up study

OBJECTIVE

To conduct a follow-up on the rate and related risk factors of probable disaster-related psychiatric disorders such as depressive disorder (major depressive episode, MDE), stress disorders, post-traumatic (posttraumatic stress disorder, PTSD), and the quality of life of the survivors of a fossil gas explosion in Taiwan 18 months after the event.

METHODS

A community-based survey of residents of a community that experienced a petrochemical gas explosion with cross-sectional assessments was conducted 18 months after the event. Two screening tools, including the Disaster-Related Psychological Screening Test (DRPST) and Short Form 12v2 (SF-12v2), were used to survey a representative sample of 388 participants.

RESULTS

The average age of 388 participants is 43.27 ± 15.98 years (males: 203, average age: 41.44 ± 15.74 years; females: 185; average age: 45.27 ± 16.03 years). Probable PTSD, probable MDE, probable PTSD and MDE, and non-PTSD or non-MDE (non-P or -M) were present in 34 (8.8%), 14 (3.6%), 9 (2.3%), and 331 (85.3%) participants, respectively. The significant associated factor for probable PTSD or MDE among those who experienced disaster was financial problems. The associated factors on different quality of life subscales were old age, physical injury, employment, educational level, financial problems, probable PTSD and probable MDE.

CONCLUSION

While participants' psychiatric status improved after 18 months, their quality of life continued to be affected, especially the quality of life of those with probable PTSD combined with MDE. Postdisaster treatment and follow-up should be addressed to a greater degree, especially for victims with mental illness, physical injuries and financial problems.

Does the Factor Structure of the Brief COPE Fit Different Types of Traumatic Events?

Abstract. The current study aims to explore the likelihood of there being a higher-order factorial model of the Brief COPE ( Carver, 1997 ) that is equally appropriate and valid for different traumatic groups (i.e., breast cancer patients and female flood survivors) at 3–4 months after the traumatic event. Both groups of participants include 180 survivors. Five factorial models for the Brief COPE were identified when reviewing the literature, and model comparisons were made by conducting confirmatory factor analyses (CFAs). The three dimensions of the Brief COPE posited by Litman (2006) and Gutiérrez, Peri, Torres, Caseras, and Valdés (2007) , namely self-sufficient coping, socially-supported coping, and avoidant coping, were supported in both traumatic populations. Tests of measurement invariance generally supported invariance (factor form, factor loadings, item intercepts, error variances, factor variances, and covariances) across groups, implying that groups perceive the latent factors in the same way and the higher-order coping across different traumatic groups is meaningful. Moreover, the relationship between the three higher-order coping factors and variables of psychological adjustment was examined. Generally, different relationships between the subtypes of coping and the outcomes of adaptation existed between female flood survivors and breast cancer patients. Further theoretical and practical implications for these relationships are discussed.

Tctex-1 controls ciliary resorption by regulating branched actin polymerization and endocytosis

The primary cilium is a plasma membrane-protruding sensory organelle that undergoes regulated assembly and resorption. While the assembly process has been studied extensively, the cellular machinery that governs ciliary resorption is less well understood. Previous studies showed that the ciliary pocket membrane is an actin-rich, endocytosis-active periciliary subdomain. Furthermore, Tctex-1, originally identified as a cytoplasmic dynein light chain, has a dynein-independent role in ciliary resorption upon phosphorylation at Thr94. Here, we show that the remodeling and endocytosis of the ciliary pocket membrane are accelerated during ciliary resorption. This process depends on phospho(T94)Tctex-1, actin, and dynamin. Mechanistically, Tctex-1 physically and functionally interacts with the actin dynamics regulators annexin A2, Arp2/3 complex, and Cdc42. Phospho(T94)Tctex-1 is required for Cdc42 activation before the onset of ciliary resorption. Moreover, inhibiting clathrin-dependent endocytosis or suppressing Rab5GTPase on early endosomes effectively abrogates ciliary resorption. Taken together with the epistasis functional assays, our results support a model in which phospho(T94)Tctex-1-regulated actin polymerization and periciliary endocytosis play an active role in orchestrating the initial phase of ciliary resorption.

An investigation of junior high students' attitudes toward amphetamine use and related forms of behavior

The purpose of the present study was to investigate the attitudes toward amphetamine use and some forms of behavior related to it. Two different kinds of junior high schools from southern Taiwan participated in this study. Five hundred and sixty-nine students supplied urine samples and filled in questionnaires. The results indicated that the prevalence rate of amphetamine use was 4.0% and the subjects had a fair level of cognition and very negative beliefs toward amphetamine use. Discriminant analyses indicated that access to amphetamine and the unlikelihood of being caught when using amphetamine were the two most important and meaningful variables in the distinction of previous using experience. School, grades, opinions about amphetamine use, the ease with which amphetamine could be obtained, and the severity of misbehavior were the most important variables in the prediction of the probable intention to use it, if amphetamine were available. However, because of the limited number of amphetamine users found in the study, any conclusions based on the results should be used cautiously. Strategies of prevention are suggested.
