The Relationship between Physical Activity Levels and Mental Health in Individuals with Spinal Cord Injury in South Korea

Exploring mitigation strategies for smog crisis in Lahore: a review for environmental health, and policy implications

Smog, a combined form of atmospheric pollutants, dust, and smoke with fog under sunlight, poses a significant threat to human health and the environment by reducing visibility. Urban air pollution exposure can cause respiratory issues like asthma, pneumonia, chronic obstructive pulmonary disease (COPD), and cardiovascular diseases like heart attacks, high blood pressure, lung cancer, and other health issues like diabetes, cognitive decline, and even birth defects. As smog has become a growing global issue with severe impacts on public health, ecosystems, and economies, this study analyzes its effects and identifies appropriate policies for its mitigation. This study aims to determine effective smog mitigation strategies for Lahore, Pakistan. A total of 50 scientific studies previously published related to PM2.5 and PM10, NO2, SO2, CO, O3 and Ch4 were examined in this study. In addition to peer-reviewed scientific research, the smog data from the last decade, from 2014 to 2024, from various sources was analyzed to deduce the necessary information to do so. Furthermore, an online survey was also conducted to gather expert opinions on key smog mitigation policies which were identified in previous studies. The findings highlight five critical areas for reducing smog in Lahore-Pakistan: Nature-based Solutions, Transportation Measures, Industrial Measures, Domestic Measures, and Public Awareness. In addition, the study emphasizes the importance of collaborative partnerships with neighboring countries to address this shared environmental challenge. As a final recommendation, an emergency plan is proposed for smog-heavy days, suggesting temporary controls on vehicle use, industrial production, and outdoor activities to mitigate immediate health risks. By combining scientific evidence, historical data, and expert perspectives, this study offers a comprehensive strategy to address smog in Lahore, further contributing to broader local, regional, and global efforts.

Physical Activity Measurement in People with Spinal Cord Injury: A Comparative Review of Different Questionnaires

Physical activity (PA) provides great health benefits for people with spinal cord injury (SCI). Consequently, the design and implementation of PA interventions addressed to this population is needed. To rigorously evaluate these interventions, the use of valid and comprehensive PA measures is crucial. Since the suitability of PA assessment tools might differ among different populations, and considering that questionnaires are one of the most frequently used tools to quantify PA, the purpose of this comparative review was to examine nine questionnaires that have been used to assess PA in people with SCI. All the questionnaires were analyzed in depth in regard to three main dimensions: (1) SCI-specific development; (2) PA domains measured and PA intensity classification; and (3) reliability and validity. After careful consideration of the evidence available on all these aspects, it is suggested that the most suitable questionnaires to be used in PA research in the SCI population are the PARA-SCI and the LTPAQ-SCI[R]. To conclude, the strengths and limitations of these two questionnaires are discussed, and specific recommendations to SCI researchers and practitioners regarding the suitability, according to the context and characteristics, of the research/intervention are provided.

Potential role of hippocampal neurogenesis in spinal cord injury induced post-trauma depression

It has been reported both in clinic and rodent models that beyond spinal cord injury directly induced symptoms, such as paralysis, neuropathic pain, bladder/bowel dysfunction, and loss of sexual function, there are a variety of secondary complications, including memory loss, cognitive decline, depression, and Alzheimer's disease. The large-scale longitudinal population-based studies indicate that post-trauma depression is highly prevalent in spinal cord injury patients. Yet, few basic studies have been conducted to address the potential molecular mechanisms. One of possible factors underlying the depression is the reduction of adult hippocampal neurogenesis which may come from less physical activity, social isolation, chronic pain, and elevated neuroinflammation after spinal cord injury. However, there is no clear consensus yet. In this review, we will first summarize the alteration of hippocampal neurogenesis post-spinal cord injury. Then, we will discuss possible mechanisms underlie this important spinal cord injury consequence. Finally, we will outline the potential therapeutic options aimed at enhancing hippocampal neurogenesis to ameliorate depression.

Psychosocial Outcomes Associated With Types and Intensities of Physical Activity in People With Spinal Cord Injury: The Mediating Role of Self-Efficacy and Functionality

BACKGROUND

Low rates of participation and quality of life (QoL) and high rates of psychological distress are common in spinal cord injury (SCI) population. Research has supported the mediating role of self-efficacy and functionality in improving psychosocial outcomes. Furthermore, evidence supports the impact of physical activity (PA) on psychosocial variables, but little is known about the types and intensities of PA. The objective of this study was to determine whether functionality and/or general self-efficacy (GSE) mediate the relationships between the various types of PA: (1) lifestyle and (2) leisure-time physical activity (LTPA); and various intensities of PA: (1) mild, (2) moderate, and (3) heavy PA with participation, psychological distress, and perception of QoL.

METHODS

The Physical Activity Recall Assessment for SCI, and measures of functionality, GSE, participation, psychological distress, and perception of QoL were administered to 159 participants. Path analysis was performed using Jeffrey's Amazing Statistics Program.

RESULTS

GSE significantly mediated, and functionality partially significantly mediated, the relationship between LTPA and psychosocial outcomes. GSE and functionality did not mediate the relationship between lifestyle activity and psychosocial outcomes.

CONCLUSIONS

It is recommended that people with SCI perform LTPA on a regular basis to achieve psychosocial benefits. These programs should be accompanied by strategies to improve GSE.

Physical and emotional consequences of excess weight as experienced by individuals with spinal cord injuries

CONTEXT/OBJECTIVE

Excess weight has the potential to carry a substantial physical and emotional burden. A better understanding of perceived consequences of excess weight may facilitate the development of patient-centered programs and interventions to promote weight management efforts in persons with spinal cord injury (SCI). The study objective was to describe consequences of excess weight from the personal perspectives of individuals with SCI.

DESIGN

Descriptive qualitative design using in-depth semi-structured interviews and thematic analysis.

SETTING

Veterans Health Administration (VHA) SCI System of Care.

PARTICIPANTS

Individuals with SCI (n-33).

OUTCOME MEASURES

Key themes from thematic analysis.

RESULTS

Participants were male (61%), ranged from 29 to 84 years of age, and about half had tetraplegia (55%). Five themes were identified that demonstrate negative consequences of excess weight experienced by individuals with SCI, including: (1) physical health conditions (including chronic conditions and SCI secondary conditions), (2) physical symptoms (such as pain, discomfort, and fatigue), (3) movement challenges, (4) appearance-related concerns, and (5) emotional impacts.

CONCLUSIONS

Carrying excess weight is concerning to individuals with SCI and in terms of consequences such onset or exacerbation of chronic conditions, SCI secondary conditions, physical symptoms, e.g. pain, movement impairment (including hampered mobility, difficult transfers and self-care), image/appearance concerns (e.g. body image, clothing misfit), and negative emotions (e.g. unhappy, sad, depressed). Our findings may inform SCI healthcare providers about the consequences of excess weight as experienced by individuals with SCI, highlighting what matters most to persons with SCI and guiding a patient-centered approach to weight management in this population.

Association between functional outcomes and psychological variables in persons with spinal cord injury

We aimed to explore the association of functional outcomes with psychological variables, including depression, anxiety, sleep quality, and suicide risk, in persons with spinal cord injuries (SCIs). The secondary aim was to determine specific functions related to the psychological variables. This retrospective study included 259 persons with SCIs who were admitted to the Korean National Rehabilitation Center between 2019 and 2021. The participants were interviewed by a psychiatrist and completed questionnaires, including the Korean Beck Depression Inventory II (K-BDI-II), Korean Beck Anxiety Index, Insomnia Severity Index, and Mini International Neuropsychiatric Interview. To assess functional outcomes, the Spinal Cord Independence Measure III (SCIM III) and Walking Index for Spinal Cord Injury were determined by a physical therapist. The findings revealed a negative correlation of SCIM III subdivisions 1 and 3 with K-BDI-II. Specifically, feeding and mobility in bed and actions to prevent pressure injuries were functional factors associated with all four psychological variables. Our findings can guide clinicians to focus on improving functional independence and activities of daily living during the management of persons with SCI to prevent psychological consequences. Developing devices that aid in improving functional independence is crucial and may improve psychological problems in such individuals.

Increased vigorous exercise and decreased sedentary activities are associated with decreased depressive symptoms in United States adults: Analysis of The National Health and Nutrition Examination Survey (NHANES) 2017-2020

Background and aims

Depression is a major public health concern that affects over 4% of the global population. Identification of new nonpharmacologic recommendations will help decrease the burden of disease. The overarching of this study was to examine the association between physical activity and depressive symptoms in a large sample of adults in the United States.

Methods

Presently, researchers utilized data from the National Health and Nutrition Examination Surveys (NHANES 2017-2020), which is a retrospective, complex, multistage, representative, and modern cohort of the United States. Adult patients ( > 18 years; N = 8091) with complete 9-item Patient Health Questionnaire (PHQ-9) information were included in the study. The PHQ-9 is a well-validated survey, per literature, scores ≥10 are considered to have clinically relevant depression. Univariable and multivariable logistic regression was fit for active and sedentary activities on clinical depression (PHQ-9 ≥ 10). The acquisition and analysis of the data within this study were approved by the National Center for Health Statistics Ethics Review Board.

Results

After adjusting for potential confounders like age, race, sex, and income, we found that increased vigorous exercise was associated with lower rates of depressive symptoms. Each extra day of vigorous exercise was associated with 11% decreased odds of depression (odd ratio [OR]: 0.89, confidence interval [CI]: 0.83-0.96, p < 0.01). Increased sedentary activity was associated with increased depression. Each extra hour per day of sedentary activity was associated with a 6% increase in odds of depression (OR: 1.06, (1.02-1.10, p < 0.01).

Conclusion

To conclude, exercise appears to be protective against depressive symptoms; however, further prospective studies are required to ascertain whether exercise causes decreased depressive symptoms.

Neuromodulation and quality of life for patient with spasticity after spinal cord injury

RATIONALE

Spasticity develops in 80% of spinal cord injury cases and negatively affects the patents' quality of life. The most common method of surgical treatment for severe spasticity is a long-term intrathecal baclofen therapy (ITB). Long-term spinal cord stimulation is another possible treatment technique. This paper aims to evaluate the changes in quality of life for patients with spasticity who have been treated with neuromodulation (SCS or ITB) in 12 months after the surgery, as well to compare the changes in quality of life for patients who have been treated with spinal cord stimulation and those who received long-term intrathecal baclofen therapy.

MATERIALS AND METHODS

The influence of spasticity, experienced by the patients with a spinal cord injury, on their quality of life was analyzed before the surgery and 12 months after it. The severity of the spinal cord damage was determined with the scale of the American Spinal Injury Association (ASIA); spasticity was evaluated with the modified Ashworth scale, Penn Spasm Frequency Scale; pain levels were determined with visual analogue scale (VAS), anxiety and depression levels - with HADS. Functional activity of the patients was evaluated with the help of the Functional Independence Measure (FIM).

RESULTS

The treatment results for 33 patients (25 men and 8 women), aged from 18 to 62, are presented. After the trial stimulation, the patients were randomly assigned to either SCS or ITB group (18 and 15 people respectively). The decrease of spasticity in both experimental groups caused lower levels of pain, less functional dependency on other people, lower stress and depression rates and, as a consequence, better quality of life and social adaptation. The obtained results for SCS and ITB groups are statistically similar.

Effect of the COVID-19 pandemic on individuals with spinal cord injury: Mental health and use of telehealth

INTRODUCTION

Limited access to health care services and the self-isolation measures due to the coronavirus disease 2019 (COVID-19) pandemic may have had additional unintended negative effects, affecting the health of individuals with spinal cord injury (SCI).

OBJECTIVES

To examine the perceived influence of the COVID-19 pandemic on individuals with SCI. First, this study looked to understand how the pandemic affected the use and perception of telehealth services for these individuals. Second, it investigated the effect of COVID-19 on mental health.

DESIGN

Cross-sectional online survey.

SETTING

Individuals with SCI living in the community in British Columbia, Canada.

PATIENTS

This survey was offered to individuals with SCI and had 71 respondents, with 34% living in a rural setting and 66% in an urban setting.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Telehealth utility, Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Disorder 7 (GAD-7), Fear of COVID-19 scale (FCV-19S), and Perceived Vulnerability to Disease (PVD).

RESULTS

Telehealth use in the SCI population has increased from 9.9% to 25.4% over the pandemic, with rates of telehealth use in urban centers nearing those of rural participants. Thirty-one percent of respondents had probable depression and 7.0% had probable generalized anxiety disorder as measured by a score of ≥10 on the PHQ-9 and GAD-7, respectively. The mean scores on FCV-19S and PVD were 17.0 (6.6 SD) and 4.29 (1.02 SD), respectively.

CONCLUSION

Telehealth use during COVID-19 has more than doubled. It is generally well regarded by respondents, although only a fourth of the SCI population has reported its use. With this in mind, it is important to understand the barriers to further adoption. In addition, higher rates of probable depression were seen than those estimated by pre-pandemic studies in other countries.
