Physical Exercise for Treatment of Mood Disorders: A Critical Review

Short-term equine interaction for reducing test anxiety and facilitating coping skill development in college students during examination periods: A preliminary study

Mental health concerns are common among college students and more prevalent during examination periods when stress and anxiety are heightened. While the benefits of equine interaction have been reported, the impact of short-term equine interaction on coping skills valuable for managing test anxiety have yet to be studied. Therefore, the purpose of this preliminary study was to evaluate the impact of short-term equine interaction during the college examination period on development of coping skills and anxiety levels associated with testing, both self-reported and those reflected in physiological measures. Full-time college students engaged in a one-hour equine interaction session held on campus at the onset of final exam week. Participants completed a survey targeting perception of anxiety levels and coping skills. Heart rate and salivary cortisol measurements were collected pre- and post-session. Paired t-tests were performed between pre- and post- session measures and correlations between survey answers and physiological measures determined. Significant reductions were found in all areas of anxiety (Overall Academics P = 0.0003, Final Exam Preparation P = 0.0003, Taking Final Exam P = 0.0003). The reduction in exam-related anxiety was positively correlated to cortisol concentrations (r = 0.69, P = 0.03) with lower concentrations (P = 0.05) and increased heart rate (P = 0.003) post-session. Regarding coping skills, improvements were observed post-session in assertiveness (P = 0.008). Skill development coupled with reduced anxiety supports the potential benefits short-term equine interaction can offer students during the high stress periods, but these findings should be confirmed with more in-depth study.

Multidisciplinary Management Strategies for Long COVID: A Narrative Review

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has caused millions of infections to date and has led to a worldwide pandemic. Most patients had a complete recovery from the acute infection, however, a large number of the affected individuals experienced symptoms that persisted more than 3 months after diagnosis. These symptoms most commonly include fatigue, memory difficulties, brain fog, dyspnea, cough, and other less common ones such as headache, chest pain, paresthesias, mood changes, muscle pain, and weakness, skin rashes, and cardiac, endocrine, renal and hepatic manifestations. The treatment of this syndrome remains challenging. A multidisciplinary approach to address combinations of symptoms affecting multiple organ systems has been widely adopted. This narrative review aims to bridge the gap surrounding the broad treatment approaches by providing an overview of multidisciplinary management strategies for the most common long COVID conditions.

Lifestyle factors and BMI attenuate relationships between biomarkers of inflammation and depressive symptoms and well-being: A cross-sectional study

Background

Mental disorders are a growing public health concern and evidence has linked chronic low-grade inflammation with depression and well-being. Research also suggests that certain modifiable lifestyle factors such as smoking, alcohol use, physical activity, diet quality and BMI are related to psychological health. These may modulate the relationship between low-grade inflammation and mental health conditions. In this study we examined inflammatory biomarker associations with two psychological health scores and investigated whether relationships are influenced by lifestyle factors and BMI.

Methods

This was a cross-sectional study of 1824 middle-to older-aged men and women randomly selected from a large primary care centre. Depressive symptoms and well-being were assessed using the 20-item Centre for Epidemiologic Studies Depression (CES-D) Scale and the World Health Organization-Five (WHO-5) Well-Being Index. Linear regression analyses were performed to examine depression and well-being score relationships with six inflammatory biomarkers, and a composite inflammatory biomarker score, adjusting for demographic characteristics, health conditions, lifestyle factors and BMI.

Results

Depression and well-being score associations with complement component 3 (CES-D only) c-reactive protein, interleukin 6, leptin, white blood cell counts, neutrophils and the inflammatory biomarker score were observed. These relationships survived adjustment for demographic variables and health conditions but were attenuated in models which included lifestyle factors and BMI. In final models, only leptin (β = 0.566, p = 0.018) and inflammatory score (β = 0.137, p = 0.004) associations with the CES-D score remained.

Conclusions

These findings suggest that the relationship between systemic low-grade inflammation and depressive symptoms and well-being may be largely explained by lifestyle factors and adiposity, highlighting the potential importance of promoting a healthy lifestyle in the treatment of depressive disorders.

The effect of physical exercises program on social functioning, alexithymia, and sense of coherence among patients with bipolar disorders: A randomized control trial

BACKGROUND

Despite evidence that physical exercises have been helpful in the treatment of various psychiatric disorders, it is unclear whether these data can be generalized to bipolar disorder. The use of physical exercises is challenging and hopeful among patients with bipolar disorders. Few studies have examined the efficacy of physical exercise for patients with bipolar disorders.

OBJECTIVE

Investigate the effect of applying physical exercises program on social functioning, alexithymia, and sense of coherence among patients with bipolar disorders.

METHODS

This study followed a randomized control trial design "pre and post-test." Patients were randomly allocated to intervention (n = 25) and control groups (Waiting list) (n = 25). The Social Functioning Scale, Toronto Alexithymia Scale, and Sense of Coherence scales were applied in the study. Pre-test and post-tests were administered to investigate the effect of applying the physical exercises program between December 2022 to March 2023.

RESULTS

A statistically significant increase in the mean sense of coherence and social functioning scores among the study group. Mean alexithymia scores were significantly decreased among the study group between pre, immediately after, and after a three-month follow-up period.

CONCLUSION

Physical exercises are an adjunctive treatment modality that is helpful for patients with bipolar disorders. Nurse educators and service providers should reconsider the physical health care requirements for patients with bipolar disorders to equip them to manage the common comorbidities in people with mental illness.

The hormesis principle of neuroplasticity and neuroprotection

Animals live in habitats fraught with a range of environmental challenges to their bodies and brains. Accordingly, cells and organ systems have evolved stress-responsive signaling pathways that enable them to not only withstand environmental challenges but also to prepare for future challenges and function more efficiently. These phylogenetically conserved processes are the foundation of the hormesis principle, in which single or repeated exposures to low levels of environmental challenges improve cellular and organismal fitness and raise the probability of survival. Hormetic principles have been most intensively studied in physical exercise but apply to numerous other challenges known to improve human health (e.g., intermittent fasting, cognitive stimulation, and dietary phytochemicals). Here we review the physiological mechanisms underlying hormesis-based neuroplasticity and neuroprotection. Approaching natural resilience from the lens of hormesis may reveal novel methods for optimizing brain function and lowering the burden of neurological disorders.

Food is medicine intervention shows promise for engaging patients attending a safety-net hospital in the Southeast United States

Public health organizations, including the Academy of Nutrition and Dietetics and the American Hospital Association, recognize the importance of achieving food and nutrition security to improve health outcomes, reduce healthcare costs, and advance health equity. In response, federal, state, and private agencies are increasingly seeking to fund healthcare-based interventions to address food insecurity among patients. Simultaneously, nutrition-based interventions targeting chronic diseases have grown across the United States as part of the broader "Food is Medicine" movement. Few studies have examined the successes, challenges, and limitations of such efforts. As Food is Medicine programs continue to expand, identifying common approaches, metrics, and outcomes will be imperative for ensuring program success, replicability, and sustainability. Beginning in 2020, the Food as Medicine (FAM) program, a multipronged, collaborative intervention at Grady Health System has sought to combat food insecurity and improve patient health by leveraging community resources, expertise, and existing partnerships. Using this program as a case study, we (1) outline the collaborative development of the FAM program; (2) describe and characterize patient engagement in the initial 2 years; and (3) summarize strengths and lessons learned for future hospital-based food and nutrition programming. As this case study illustrates, the Food as Medicine program provides a novel model for building health equity through food within healthcare organizations.

Fatigue and Physical Activity in People after COVID-19 in Poland

OBJECTIVES

The purpose of this research was to look at the amount of fatigue and physical activity (PA) in individuals after COVID-19 in Poland and the correlation between fatigue and PA.

METHODS

The online research was carried out among adult Polish residents (122 women and 82 men) who had tested positive for SARS-CoV-2 during the previous year. The level of fatigue was measured using the Modified Fatigue Impact Scale (MFIS). The PA level was assessed using the International Physical Activity Questionnaire (IPAQ).

RESULTS

A total of 46.6% of the subjects had been ill with COVID-19 for more than 6 months before the time of the survey response. The MFIS total measure is 77 of the maximum score, and the median is 17. A total of 26% of respondents reported low activity, while 41% of respondents reported high activity. A statistically significant negative relationship was found between PA level and total fatigue score. The best scores for fatigue and PA were obtained by the subjects with mild COVID-19. The time since diagnosis (as opposed to older age and female sex) was not clearly associated with most measures.

CONCLUSIONS

PA may play an important role in regulating the severity of fatigue; it should be increased, especially in patients after COVID. Further studies are also needed to investigate the mechanism of differences in fatigue and PA.

[Efectividad de una intervención multimodal para la mejora de la atención al dolor crónico.]

OBJECTIVE

The prevalence of chronic pain in Spain is 17%, which causes suffering and significant loss of quality of life. Therapies should not focus only on pain reduction, to improve function and quality of life are necessary. Currently, it is committed to combining drugs and other therapies such as relaxation, meditation, cognitive behavioral therapy, targeted exercises, healthy lifestyles and techniques to increase self-esteem and motivation for change. These therapies can be used as part of a multimodal approach, forming part of multicomponent programs or workshops. In this paper we proposed to evaluate the effectiveness of a workshop developed from the Hospital San Juan de Dios del Ajarafe, that integrated different non-pharmacological therapies in the control of chronic non-oncologic pain and to analyze patients' perceptions of the techniques applied and how they affected pain and lifestyles.

METHODS

An intragroup before-after study (beginning-end of the workshop) was carried out, comparing pain, well-being, drug use, quality of life, and self-esteem. Surveys were conducted to deepen more qualitative aspects and identify improvements. The workshop consisted of psychoeducational action and training for the mental control of pain and emotions, based on the active participation of the patient in the management of his disease, promoting self-care and self-esteem, and aiming to improve well-being and quality of life. It consisted of 5 sessions of 3 hours (1 per week); of a group, interactive and practical nature. Statistical analysis was performed with SPSS vs.27.0. To compare related measures (before-after) we used Student's T tests for paired samples and Wilcoxon's test and to compare independent groups, Student's T and Mann Whitney's U; for the qualitative variables, we used Chi-Square and Fisher's test.

RESULTS

Four workshops were evaluated in which 63 patients participated, with a mean age of 57.6 (SD:11.37) years, 60 (95.2%) of them were women. At the end of the workshop pain decreased 1.5 median (-2.0-0) and well-being increased 2.0 (0-2.0); quality of life increased a median of 0.121 (SD: 0.209), health status 16.8 (23.78) and self-esteem 2.74 (4.73); [p<0.001]. The best valued techniques were meditations, mainly mental analgesia, affirmations in the mirror and self-esteem techniques.

CONCLUSIONS

Overall satisfaction with the workshop is 9.8 out of 10. There is a pain control and improvement in quality of life, self-perception of health status, well-being and self-esteem.

Diet and physical activity and metabolic disorders in patients with schizophrenia and bipolar affective disorder in the Polish population

Introduction

There are numerous reports of a higher prevalence of metabolic disorders in patients with schizophrenia and bipolar disorder (BD), yet its connections to diet and physical activity remain not fully explained. This article aimed to evaluate diet, physical activity and selected biochemical and anthropometric parameters associated with metabolism in patients with schizophrenia and BD and to analyse the relationships between these variables in the subjects.

Materials and Methods

A total of 126 adults participated in the study: 47 patients with schizophrenia, 54 patients with BD and 25 patients in mental illness remission (reference group). Data were collected on the underlying illness and concomitant illnesses, and the severity of symptoms of the current episode was assessed using the following scales: PANSS, MADRS and YMRS. An assessment of the subjects' diet (KomPAN questionnaire) and their physical activity (International Physical Activity Questionnaire) was carried out. Anthropometric and blood pressure measurements were taken and BMI and WHR were calculated. Serum concentrations of fasting glucose, TSH, total cholesterol, LDL and HDL fractions, triglycerides and leptin, ghrelin and resistin were determined. For statistical analysis, the significance level was set at 0.05. For multiple comparisons one way ANOVA or Kruskal Wallis were used with post hoc Tukey and Dunn tests, respectively. To determine correlation of variables, Pearson's linear correlation coefficient or Spearman's rank correlation coefficient were used.

Results

A total of 50.8% of the subjects had at least one metabolic disorder-most commonly excessive body weight (66.7%) and abdominal obesity (64.3%). Patients did not differ significantly in terms of physical activity, but they did differ in mean time spent sitting-with this being significantly longer for all groups than in the general population. The subjects differed in diet: patients with BD consumed less unhealthy foods than patients with schizophrenia. The highest correlations between physical activity, diet and variables defining metabolic disorders were found in patients with BD. Only in patients with schizophrenia were there significant correlations between the course of the disease and physical activity.

Discussion

The results suggest the existence of associations between diet, physical activity, and metabolic disorders in both BD and schizophrenia patients. They also suggest a tendency among those patients to spend long periods of time sitting.

Distinct effect of exercise modes on mood-related behavior in mice

Exercise can afford several benefits to combat mood disorders in both rodents and humans. Engagement in various physical activities upregulates levels of neurotrophic factors in several brain regions and improves mental health. However, the type of exercise that regulates mood and the underlying mechanisms in the brain remain elusive. Herein, we performed two distinct types of exercise and RNA sequencing analyses to investigate the effect of exercise on mood-related behaviors and explain the distinct patterns of gene expression. Specifically, resistance exercise exhibited reduced immobility time in the forced swim test when compared with both no exercise and treadmill exercise (in the aerobic training [AT] group). Interestingly, anxiety-like behaviors in the open field and nest-building tests were ameliorated in the AT group when compared with those in the control group; however, this was not observed in the RT group. To elucidate the mechanism underlying these different behavioral changes caused by distinct exercise types, we examined the shift in the gene expression pattern in the hippocampus, a brain region that plays a critical role in regulating mood. We discovered that 38 and 40 genes were altered in the AT and RT groups, respectively, compared with the control group. Both exercises regulated 16 common genes. Compared with the control group, mitogen-activated protein kinase (MAPK) was enriched in the AT group and phosphatidylinositol-3-kinase (PI3K)/AKT and neurotrophin signaling pathways were enriched in the RT group, as determined by bioinformatics pathway analysis. PCR results revealed that Cebpβ expression was increased in AT group, and Dcx expression was upregulated in both groups. Our findings indicate that different exercise types may exert substantially distinct effects on mood-like behaviors. Accordingly, appropriate types of exercise can be undertaken based on the mood disorder to be regulated.

Reorganization of Brain Networks as a Substrate of Resilience: An Analysis of Cytochrome c Oxidase Activity in Rats

The unpredictable chronic mild stress (UCMS) model has been used to induce depressive-like symptoms in animal models, showing adequate predictive validity. Our work aims to evaluate the effects of environmental enrichment (EE) on resilience in this experimental model of depression. We also aim to assess changes in brain connectivity using cytochrome c oxidase histochemistry in cerebral regions related to cognitive-affective processes associated with depressive disorder: dorsal hippocampus, prefrontal cortex, amygdala, accumbens, and habenula nuclei. Five groups of rats were used: UCMS, EE, EE + UCMS (enrichment + stress), BG (basal level of brain activity), and CONT (behavioral tests only). We assessed the hedonic responses elicited by sucrose solution using a consumption test; the anxiety level was evaluated using the elevated zero maze test, and the unconditioned fear responses were assessed by the cat odor test. The behavioral results showed that the UCMS protocol induces elevated anhedonia and anxiety. But these responses are attenuated previous exposure to EE. Regarding brain activity, the UCMS group showed greater activity in the habenula compared to the EE + UCMS group. EE induced a functional reorganization of brain activity. The EE + UCMS and UCMS groups showed different patterns of connections between brain regions. Our results showed that EE favors greater resilience and could reduce vulnerability to disorders such as depression and anxiety, modifying metabolic brain activity.

Mood Status Response to Physical Activity and Its Influence on Performance: Are Chronotype and Exercise Timing Affect?

PURPOSE

It is well known that there is an obvious 24 h diurnal variation in the individual's mood state and physiological activity, and training at different times of the day may lead to different exercise performance and metabolic outcomes; however, the time-dependent effect of emotional state on physical activity and the influence of its circadian rhythm on exercise performance are still not comprehensively understood. Based on this, this study summarizes the rhythmic experimental research in the field of sport psychology, and it aims to provide the basis for coaches to optimize sports training scientifically and to improve the mental health of the related crowd to the greatest extent.

METHODS

The systematic review was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We searched the PubMed, Web of Science, Medline, and CNKI databases for relevant literature; the search scope was research before September 2022.

RESULTS

13 studies comprising 382 subjects examined the effects of exercise timing on mood responses to exercise or the effects of circadian rhythms of mood on exercise performance, which included 3 RCTs and 10 Non-RCTs. The subjects included athletes (both training or retired), college students, and healthy adults. Two studies were designed for long-term exercise intervention (aerobic training and RISE) and the rest for acute intervention (CrossFit training, HIIT, aerobic combined with muscle conditioning training, constant power exhaustion training, and cycling) or physical function tests (RSA + BTV tests, 30 s Wingate test, muscle strength + CMJ + swimming performance test, RSSJA, shooting accuracy tests + 10 × 20 m dribbling sprint, 200 m time trials). All trials reported specific exercise timing; of these, 10 studies reported subjects' chronotypes, most commonly using the MEQ scale, while 1 recorded with the CSM. Mood responses were assessed with the POMS scale in 10 studies, while 3 other studies used the UMACL, PANAS, and GAS scales, respectively.

CONCLUSION

There was much inconsistency between the results, with subjects likely to be exposed to more sunlight (the main timing factor of the circadian rhythm) during early morning exercise, resulting in feeling more positive emotions; however, following a night's rest, delayed responses and poor functioning of the various organ systems of the human body may also lead to higher feelings of fatigue and negative emotions indirectly. Conversely, for athletes, their physical function tests are also more susceptible to the circadian rhythm of emotions, suggesting the importance of synchronizing them. In addition, night owls' emotional state during physical activity seems to be more susceptible to exercise timing than that of early birds. In order to achieve the best emotional state, it is suggested that night owls arrange courses in the afternoon or evening in future training.

Emotional and physical-related experiences as potential mechanisms linking physical activity and happiness: Evidence from the Ghana Aging, Health, Psychological Well-being, and Health-seeking Behavior Study

This study examines the association between physical inactivity (PI) and happiness among Ghanaian older adults and whether emotional and physical-related experiences (EPE) mediate the association. Data from the Aging, Health, Psychological Well-being and Health-seeking Behavior Study (AgeHeaPsyWel-HeaSeeB) conducted in 2016-2018 among 1201 older Ghanaians were analyzed. Happiness was assessed with the self-rated and cross-culturally validated item on a 5-point scale. PI was evaluated with the International Physical Activity Questionnaire (IPAQ). Hierarchical linear regressions and mediation analyses were performed to estimate the hypothesized associations. Results showed that PI was significantly associated with lower levels of happiness (β = -0.053, p < .001) net of potential confounders. The association of PI with happiness was attenuated and fully mediated by pain, sleep problems, loneliness, anxiety, and boredom. Moreover, in terms of the cross-level interaction effects, PI moderated the happiness-pain (β = -0.029, p < .005), happiness-social isolation (β = -0.024, p < .05), and happiness-boredom (β = -0.023, p < .005) associations. Our data suggest that EPE may explain why PI decreases happiness in old age. Findings provide valuable insight into the interventions and decisions to improve subjective well-being and quality of life in old age.

An examination of bidirectional associations between physical activity and mood symptoms among individuals diagnosed and at risk for bipolar spectrum disorders

OBJECTIVES

Activation, a construct including energy and activity, is a central feature of Bipolar Spectrum Disorders (BSDs). Prior research found motor activity is associated with affect, and this relationship may be stronger for individuals with BSDs. The aims of this study were to investigate bidirectional relationships between physical activity and mood and evaluate whether bipolar risk status moderated potential associations.

METHODS

Young adults at low-risk, high-risk, and diagnosed with BSD participated in a 20-day EMA study in which they wore an actiwatch to measure physical activity and sleep/wake cycles. They also reported depressive and hypo/manic symptoms three times daily. Multilevel linear models were estimated to examine how bipolar risk group moderated bidirectional relationships between physical activity and mood symptoms at within-day and between-day timescales.

RESULTS

Physical activity was significantly associated with subsequent mood symptoms at the within-day level. The relationship between physical activity and depressive symptoms was moderated by BSD risk group. An increase in physical activity resulted in a greater reduction of depressive symptoms for the BSD group compared to the low-risk and high-risk groups.

CONCLUSIONS

Interventions targeting activity like behavioral activation may improve residual inter-episode mood symptoms.

Relationship between university students' physical activity and mobile phone dependence: Mediating effect of subjective well-being and moderating effect of psychological capital

Background

With the ongoing development of the information society, the Internet and smartphones have become an essential way of life, but also fostered the problem of mobile phone dependence. Physical activity and subjective well-being have both been shown to correlate with mobile phone dependence, but the impact of subjective well-being on the relationship between physical activity and mobile phone dependence is not fully understood. This study investigates subjective well-being as a potential mediating variable in the relationship. It also investigates whether psychological capital moderates the association between subjective well-being and mobile phone dependence.

Methods

A total of 9,569 students from 38 universities in Jiangsu Province were selected. Participants were surveyed via the online questionnaire distribution platform Questionnaire Star. Common method bias test and Pearson correlation tests were used to analyze the study indicators, and the theoretical model for this study was validated using Process plug-in developed by Hayes and set at p < 0.05 (two- tail) as statistically significant.

Results

The levels of physical activity, subjective well-being, and psychological capital were all significantly higher for male students than female students. However, female students had a significantly higher level of mobile phone dependence. As predicted, there was a direct negative correlation between physical activity and mobile phone dependence, and subjective well-being mediated that relationship. Psychological capital moderated the relationship between subjective well-being and mobile phone dependence. It also positively moderated the indirect effect between physical activity and mobile phone dependence via subjective well-being.

The relationship between physical activity states and depressive symptoms: Using ambulatory assessment to characterize day-to-day associations among individuals with and without bipolar spectrum disorder

INTRODUCTION

The role of activation in the pathogenesis of bipolar spectrum disorders (BSD) is of growing interest. Physical activity is known to improve mood, but it is unclear whether low activity levels contribute to inter-episode depressive symptoms observed in BSD. This study examined whether sedentary and vigorous activity, as well as the timing of the activity, were differentially associated with next-day depressive symptoms for individuals at low risk for BSD, high-risk for BSD, and diagnosed with BSD.

METHODS

Young adults (n = 111, ages 18-27) from three groups (low BSD risk, high BSD risk, and BSD diagnosis), participated in a 20-day ecological momentary assessment study. Physical activity was measured via wrist actigraphy counts. The percentage of time awake spent in sedentary, light, moderate, and vigorous activity states was calculated, as was the percentage of morning hours and evening hours in each activity state. Multilevel models examined whether the BSD risk group moderated associations between sedentary and vigorous activity and depressive symptoms, which were assessed three times daily.

RESULTS

There were no between-group differences in time spent in each activity state, nor were there main effects of sedentary or vigorous activity on depression. Increased time spent engaging in vigorous activity was associated with a greater reduction in subsequent depressive symptoms for the BSD group. An increase in the evening, but not morning, vigorous activity was significantly associated with a reduction in subsequent depressive symptoms for the BSD group after controlling for chronotype.

CONCLUSIONS

Interventions targeting physical activity may effectively help regulate inter-episode mood disturbances in BSD.

A physically active lifestyle is associated with lower long-term incidence of bipolar disorder in a population-based, large-scale study

Background

Physical activity has been proposed to be beneficial for the symptomatic control of bipolar disorder, but the duration of the effects, sex-specific mechanisms, and impact of exercise intensity are not known.

Method

With an observational study design, we followed skiers and age and sex-matched non-skiers from the general population to investigate if participation in a long-distance cross-country ski race (Vasaloppet) was associated with a lower risk of getting diagnosed with bipolar disorder. Using the Swedish population and patient registries, skiers in Vasaloppet and age and sex-matched non-skiers from the general population were analyzed for any diagnosis of bipolar disorder after participation in the race. Additionally, we used finishing time of the ski race as a proxy for intensity levels to investigate if exercise intensity impacts the risk of bipolar disorder among the physically active skiers.

Results

Previous participation in a long distance ski race (n = 197,685, median age 36 years, 38% women) was associated with a lower incidence of newly diagnosed bipolar compared to an age and sex-matched general population (n = 197,684) during the up to 21 years follow-up (adjusted hazard ratio, HR = 0.48). The finishing time of the race did not significantly impact the risk of bipolar disorder in men. Among women, high performance (measured as the finishing time to complete the race, a proxy for higher exercise dose) was associated with an increased risk of bipolar disorder compared to slower skiing women (HR = 2.07).

Conclusions

Our results confirm that a physically active lifestyle is associated with a lower risk of developing bipolar disorder. Yet, to elucidate the direction of causality in this relationship requires complementary study designs. And the influence of physical performance level on the risk of bipolar disorder warrants further examinations among women.

Examining the Effect of Increased Aerobic Exercise in Moderately Fit Adults on Psychological State and Cognitive Function

Regular physical exercise can decrease the risk for obesity, diabetes, and cardiovascular disease, increase life expectancy, and promote psychological health and neurocognitive functioning. Cross-sectional studies show that cardiorespiratory fitness level (VO2 max) is associated with enhanced brain health, including improved mood state and heightened cognitive performance. Interventional studies are consistent with these cross-sectional studies, but most have focused on low-fit populations. Few such studies have asked if increasing levels of physical activity in moderately fit people can significantly enhance mood, motivation, and cognition. Therefore, the current study investigated the effects of increasing aerobic exercise in moderately fit individuals on psychological state and cognitive performance. We randomly assigned moderately fit healthy adults, 25-59 years of age, who were engaged in one or two aerobic exercise sessions per week to either maintain their exercise regimen (n = 41) or increase their exercise regimen (i.e., 4-7 aerobic workouts per week; n = 39) for a duration of 3 months. Both before and after the intervention, we assessed aerobic capacity using a modified cardiorespiratory fitness test, and hippocampal functioning via various neuropsychological assessments including a spatial navigation task and the Mnemonic Similarity Task as well as self-reported measures including the Positive and Negative Affect Scale, Beck Anxiety Inventory, State-Trait Anxiety Inventory, Perceived Stress Scale, Rumination Scale, Eating Disorders Examination, Eating Attitudes Test, Body Attitudes Test, and Behavioral Regulation of Exercise Questionnaire. Consistent with our initial working hypotheses, we found that increasing exercise significantly decreased measures of negative affect, including fear, sadness, guilt, and hostility, as well as improved body image. Further, we found that the total number of workouts was significantly associated with improved spatial navigation abilities and body image as well as reduced anxiety, general negative affect, fear, sadness, hostility, rumination, and disordered eating. In addition, increases in fitness levels were significantly associated with improved episodic memory and exercise motivation as well as decreased stress and disordered eating. Our findings are some of the first to indicate that in middle-aged moderately-fit adults, continuing to increase exercise levels in an already ongoing fitness regimen is associated with additional benefits for both psychological and cognitive health.

Examining Anxiety, Sleep Quality, and Physical Activity as Predictors of Depression among University Students from Saudi Arabia during the Second Wave of the COVID-19 Pandemic

Conducted during the second wave of the pandemic, this cross-sectional study examined the link between sleep quality, physical activity, exposure, and the impact of COVID-19 as predictors of mental health in Saudi undergraduate students. A convenience sample of 207 participants were recruited, 89% of whom were females and 94% were single. The measures included questionnaires on the level of exposure and the perceived impact of COVID-19, a physical activity measure, GAD-7, PHQ-9, and PSQI. The results indicated that approximately 43% of participants exhibited moderate anxiety, and 50% were at risk of depression. Overall, 63.93% of students exposed to strict quarantine for at least 14 days (n = 39) exhibited a high risk of developing depression (χ2(1) = 6.49, p < 0.05, ϕ = 0.18). A higher risk of depression was also found in students whose loved ones lost their jobs (χ2(1) = 4.24, p < 0.05, ϕ = 0.14). Moreover, there was also a strong association between depression and anxiety (β = 0.33, p < 0.01), sleep quality (β = 0.32, p < 0.01), and the perceived negative impact of COVID-19 on socio-economic status (β = 0.26, p < 0.05), explaining 66.67% of depression variance. Our study highlights the socio-economic impact of this pandemic and the overwhelming prevalence of depression.

Multimodal Chronic Pain Therapy for Adults via Smartphone: Randomized Controlled Clinical Trial

BACKGROUND

Combination therapies delivered remotely via the internet or mobile devices are increasingly being used to improve and promote the self-management of chronic conditions. However, little is known regarding the long-term effects of these interventions.

OBJECTIVE

The aim of this study is to evaluate the effectiveness of a multimodal intervention program that measures associated variables such as catastrophizing, pain acceptance, and quality of life using a mobile device in people with chronic pain in an outpatient setting.

METHODS

A randomized controlled clinical trial was performed using parallel treatment groups. A total of 209 patients with chronic musculoskeletal pain were randomly assigned to one of the two study arms. The intervention group received a standard web-based psychosocial therapy-type program of activities through a smartphone for 6 weeks. The control group only had access to the Find out more section of the app, which contained audiovisual material for pain management based on a self-help approach. The primary outcome was catastrophizing measured using the Pain Catastrophizing Scale (PCS). Secondary outcomes were pain acceptance measured using the Chronic Pain Acceptance Questionnaire and health-related quality of life measured using the EuroQol Visual Analogue Scale. Assessments were conducted at baseline (T1), after treatment (T2), and at the 3-month follow-up (T3). The variations between the different phases were assessed using the percentage change rescaled with log base 2. The Cohen d was calculated based on the results of the linear mixed model. The investigators of the study who evaluated the results were not involved in patient recruitment and were blinded to the group assignment.

RESULTS

Positive effects were found in the intervention group (T2-T1) in catastrophizing between the baseline and posttreatment phases (P<.001) and in helplessness (-0.72 vs 0.1; P=.002), rumination (-1.59 vs -0.53; P<.001), acceptance (0.38 vs 0.05; P=.001), and quality of life (0.43 vs -0.01; P=.002), although no significant changes were found for magnification (0.2 vs 0.77; P=.14) and satisfaction with health (0.25 vs -0.27; P=.13). Three months after treatment, significant differences were observed in the intervention group for the outcome variable of catastrophizing (PCS; -0.59 vs 0.2; P=.006) and the PCS subscales of helplessness (-0.65 vs 0.01; P=.07), rumination (1.23 vs -0.59; P=.04), and magnification (0.1 vs 0.86; P=.02).

CONCLUSIONS

The results of our study suggest that app-based mobile multidimensional treatments for adults with chronic pain improve catastrophizing, quality of life, and psychological flexibility immediately after treatment and that the effects are maintained for the primary outcome of catastrophizing for at least 3 months following treatment. Moreover, they promote self-management and can be used to complement face-to-face pain treatments.

Self-reported sleep and exercise patterns in patients admitted with suicidal attempts: a cross-sectional comparative study

BACKGROUND

There is evidence that sleep disturbances and exercise are risk factors for suicide attempts; however, whether sleep disturbances are independently associated with suicide attempts is debatable. We compared the sleep and exercise patterns of individuals who attempted suicide to those of the general population and investigated whether sleep disturbances were independently associated with suicide attempts.

METHODS

Over a year, individuals presented to the emergency department at Hamad General Hospital and Mental Health Services in Doha with suicide attempts (n = 127) filled out questionnaires on sleep and exercise, demographics, and clinical measures. A control group (n = 126) from two primary care centers filled out the same questionnaires during the same period.

RESULTS

Subjects in the suicide group were significantly younger, single, had a lower level of education, and showed considerably more early insomnia, daytime tiredness, interrupted sleep, and no regular exercise. The most common diagnoses seen with suicidality were adjustment disorder and major depression, and the most common method used to attempt suicide was an overdose. After multiple regression analysis, being Arab, belonging to the category "other nationalities," unemployment, and early insomnia were significantly associated with an increased risk of suicide attempts.

CONCLUSION

This is the first comparative study on suicide in the Arabian Gulf. Individuals in Qatar with acute stress, depressive symptoms, sleep disturbances, and lack of exercise are at increased risk of attempting suicide. Thus, clinicians need to routinely screen for sleep and physical activity because of their significant contribution to physical and mental well-being.

Validation of a Lithuanian-Language Version of the Brunel Mood Scale: The BRUMS-LTU

Mood can be considered as a diffuse and global emotional state, with both valence and arousal characteristics, that is not directed towards a specific object. Investigation of moods in specific language and cultural contexts relies on the availability of appropriately validated measures. The current study involved the translation and validation of the Brunel Mood Scale (BRUMS) from English into Lithuanian. The 24-item, 6-factor scale, referred to as the BRUMS-LTU, was administered to 746 participants who were fluent in Lithuanian (nmen = 199 (26.7%), nwomen = 547 (73.3%); age range = 17-78 years, M = 41.8 years, SD = 11.4 years). Confirmatory factor analysis showed an adequate fit of the hypothesized measurement model to the data (CFI  =  0.954, TLI  = 0 .944, RMSEA  = 0 .060 [CI 0.056, 0.064], SRMR = 0.070) and multi-sample analysis supported configural, metric, scalar, and residual invariance across genders. Concurrent measures (i.e., Perceived Stress Scale, Big Five Personality Test) correlated with subscale scores in line with theoretical predictions, supporting both convergent and divergent validity. Internal consistency coefficients of the six subscales were satisfactory. Mood scores varied significantly by gender, with men generally reporting more positive moods than women. Findings support the adequacy of the psychometric properties of the BRUMS-LTU. Thus, the scale can be recommended for use in further psychological studies of mood in Lithuania and may also be useful for applied practitioners.

Utilization of healthcare and prescription medicines after non-pharmacological interventions for depression - A 3-year register follow-up of an RCT in primary care

•

A 3-year register follow-up of an RCT for depression interventions was conducted.

•

Healthcare utilization and dispensed medicines were used as register outcomes.

•

The interventions had no effect on consultations for mental illness during follow-up.

•

Both interventions are appropriate additions to mild-moderate depression care.

Depression is a common, recurrent disorder. There is a need for readily available treatments with few negative side effects, that demands little resources and that are effective both in the short- and long term.

Our aim was to investigate the long-term effectiveness of two different interventions; physical exercise and internet-based cognitive behavioural therapy (internet-CBT), compared to usual care in patients with mild to moderate depression in a Swedish primary care setting.

We performed a register-based 3-year follow-up study of participants in the randomized controlled trial REGASSA (n = 940) using healthcare utilization and dispensed medicines as outcomes.

We found no difference between the three groups regarding proportion of participants consulting healthcare due to mental illness or pain during follow-up. Regarding number of consultations, there was no difference between the groups, except for consultations related to pain. For this outcome both treatment arms had significantly fewer consultations compared to usual care, during year 2–3, the risk ratio (RR) for physical exercise and internet-CBT was 0.64 (95% CI = 0.43–0.95) and 0.61 (95% CI = 0.41–0.90), respectively.

A significantly lower proportion of patients in both treatment arms were dispensed hypnotics and sedatives year 2–3 compared to the usual care arm, RR for both physical exercise and internet-CBT was 0.72 (95% CI = 0.53–0.98). No other differences between the groups were found.

In conclusion, considering long-term effects, both physical exercise and internet-CBT, being resource-efficient treatments, could be considered as appropriate additions for patients with mild to moderate depression in primary care settings.

Trial registration: The original RCT was registered with the German Clinical Trial Register (DRKS study ID: DRKS00008745).

The UP150: A Multifactorial Environmental Intervention to Promote Employee Physical and Mental Well-Being

Physical activity (PA) is a major health factor and studies suggest workplaces could promote PA by modifying office design, motivational strategies and technology. The present study aims to evaluate the efficiency of UP150, a multifactorial workplace intervention for the improvement and maintenance of the level of physical fitness (PF) and wellbeing. Forty-five employees were randomly divided into the experimental (EG) and control (CG) groups. The PF was assessed pre-post intervention using the cubo fitness test (CFT), the amount of PA was evaluated using the IPAQ questionnaire and accelerometers while the workload was assessed using the NASA-TLX questionnaire and psycho-physical health by using the SF-12 questionnaire. The EG worked in UP150 offices while the CG worked in their usual offices for 8 weeks. The EG and CG came back 4 weeks after the intervention for CFT retention. The EG improved CFT motor efficiency and the amount of moderate PA, while it reduced mental load. The EG retained reached motor efficiency levels 4 weeks after the intervention. No differences were found in IPAQ. The UP150 demonstrated to be a proactive environment and to be efficient in the promotion of PA, improving PF and mental health while decreasing mental load.

Myalgic Encephalomyelitis/Chronic Fatigue Syndrome: Essentials of Diagnosis and Management

Despite myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) affecting millions of people worldwide, many clinicians lack the knowledge to appropriately diagnose or manage ME/CFS. Unfortunately, clinical guidance has been scarce, obsolete, or potentially harmful. Consequently, up to 91% of patients in the United States remain undiagnosed, and those diagnosed often receive inappropriate treatment. These problems are of increasing importance because after acute COVID-19, a significant percentage of people remain ill for many months with an illness similar to ME/CFS. In 2015, the US National Academy of Medicine published new evidence-based clinical diagnostic criteria that have been adopted by the US Centers for Disease Control and Prevention. Furthermore, the United States and other governments as well as major health care organizations have recently withdrawn graded exercise and cognitive-behavioral therapy as the treatment of choice for patients with ME/CFS. Recently, 21 clinicians specializing in ME/CFS convened to discuss best clinical practices for adults affected by ME/CFS. This article summarizes their top recommendations for generalist and specialist health care providers based on recent scientific progress and decades of clinical experience. There are many steps that clinicians can take to improve the health, function, and quality of life of those with ME/CFS, including those in whom ME/CFS develops after COVID-19. Patients with a lingering illness that follows acute COVID-19 who do not fully meet criteria for ME/CFS may also benefit from these approaches.

Multimodal Therapeutic Approach in Women with High Risk of Metabolic Syndrome-A Single Group One Center Pre-Post Study

The study aims to determine the impact of multimodal therapeutic approach on self-perceived stress in women with high risk of Metabolic Syndrome (MetS). The study involved 43 women aged 60 years and over (mean 68.6 ± 6.5) participating in a Mental Health Promotion Program. Over the 3-month course of the project, all of the participants attended meetings of a support group (60-min sessions twice a week). During these meetings, they took part in general fitness training (20 min), dancing (20 min), as well as health-promoting education and psychoeducation sessions (20 min). Moreover, the participants were encouraged to modify their diet to reduce their daily fat and sugar intake. Stress levels were assessed using the Perception of Stress Questionnaire (PSQ). Mood was measured with the Geriatric Depression Scale (GDS-30). In all of the subjects, a body composition analysis was performed using a Tanita BC-545N analyzer. Abdomen and hip circumference were measured to determine the waist-hip ratio. Weight and height were measured to determine the BMI score. At the beginning of the project, the intensity of stress correlated with the level of depressive symptoms (GDS), Body Mass Index (BDI), and the amount of visceral fat. Three months of participation in the Mental Health Promotion Program resulted in a significant reduction in stress intensity (p < 0.01). At the end of the project, all of the participants expressed their willingness to continue their participation in the classes, which is very important as there is a need to conduct long-term health-promoting activities in the age group in question.

A systematic review and meta-analysis of the effect of whole body cryotherapy on mental health problems

OBJECTIVE

To give an overview of the nature and methodological quality of studies on whole body cryotherapy (WBC) as add-on intervention for mental health problems.

METHODS

A meta-analysis according to PRISMA guidelines was conducted (Prospero registration: CRD42020167443). Databases MEDLINE, PsycINFO and the Cochrane Library were searched. Risk of bias was scored according to the Cochrane ROBINS-I-tool to which an extra bias-dimension of allegiance bias was added. Within and between Hedges' g pooled effect sizes were calculated for the main aspect of mental health measured. Treatment efficacy was examined using a random effects model. Heterogeneity was examined through identification of visual outliers and by I² statistics.

RESULTS

Out of 196 articles coming up from the search, ten studies met all inclusion criteria, six of which were (randomized) controlled trials. Together these studies report on a total of 294 participants receiving WBC. The within-group pooled effect size for mental health problems is large (Hedges' g = 1.63, CI: 1.05-2.21), with high heterogeneity (I² = 93%). Subgroup analyses on depressive symptoms and quality of life (QOL) showed a diminution of heterogeneity to moderate. Effect sizes for depressive symptoms are very large (Hedges' g = 2.95, CI: 2.44-3.45) and for QOL medium (Hedges' g = 0.70, CI: 0.15-1.24). The between-group pooled effect size is medium (Hedges' g = 0.76, CI: 0.17-1.36).

CONCLUSIONS

Results indicate preliminary evidence for WBC as efficacious add-on intervention for mental health problems, especially depressive symptoms. Further research in the form of RCTs with larger numbers of participants is needed.

Physical activity influences the mobile phone addiction among Chinese undergraduates: The moderating effect of exercise type

BACKGROUND AND AIMS

Mobile phone addiction (MPA) has recently aroused much attention due to its high incidence and considerable health hazards. Although some existing studies have documented that physical activity is negatively associated with MPA, it is little known about the potential effects underlying this relation. The aim of this study was to investigate the relationship between physical activity and MPA among undergraduates in China, and to further examine the moderating effect of exercise type in the relation between them.

METHODS

By the quota sampling, a total of 650 participants engaged in this survey and completed relevant measurements including physical activity rating scale-3 (PARS-3) and mobile phone addiction tendency scale (MPATS).

RESULTS

Gender (β = 0.271, P < 0.05) and major (β = -0.169, P < 0.05) could significantly predict MPA, respectively, and physical activity was an imperative protective factor to decrease MPA (β = -0.266, P < 0.001). While the physical activity level enhanced from none exercise to medium exercise, an optimum dose-response relationship would emerge between physical activity and MPA (F (3,604) = 4.799, P < 0.01). Most important, the relation between physical activity and MPA can be moderated by exercise type. Especially in terms of aerobic endurance exercise, the higher level of physical activity the undergraduates performed, the lower degree of MPA would be suffered by them (β = -0.266, P < 0.001).

DISCUSSION

These findings could be conducive to better understand the positive and potential effects of physical activity on the intervention in MPA, and served as a persuasive evidence that as for university students, actively engaging in aerobic endurance exercise with the medium activity level would be a practicable exercise strategy to deal with MPA in daily lifestyle behavior.

Exercise behavior patterns and associations with subjective well-being during the COVID-19 pandemic: A cross-sectional study in Brazil

Introduction

The COVID-19 pandemic has affected the behavior and practice of planned and structured physical exercises. This study aimed to investigate the association between changes in physical exercise behavior and subjective well-being during the COVID-19 pandemic in Brazil.

Methods

This cross-sectional study was performed in Brazil and included a total of 595 individuals recruited through social media platforms, personal and professional contacts. Each participant responded to self-completed questionnaire via an online survey between March 29 and May 7, 2020. The characteristics of physical exercise (frequency, intensity, and duration) were collected before and during the pandemic. The subjective state of mood was measured through the Profile of Mood States (POMS) questionnaire during the pandemic. A generalized linear model was employed for the analysis.

Results

Exercising during the pandemic only promoted protective effects on the subjective mood. An exercise frequency of 3-5 days/week was associated with improved vigor and between 6-7 days/week with improved vigor and total mood when compared to not exercising at all (p < .005). A moderate intensity was associated with improved vigor, and a high intensity with improved vigor, total mood, and less fatigue in comparison to low-intensity exercise programs (p < 0.05). Maintaining the same duration of exercise sessions during the pandemic was associated with lower scores of depression/anxiety, fatigue and irritability, and improved vigor and total mood, while performing longer sessions with improved vigor when compared to short exercise sessions (p < .005).

Conclusion

Regular exercising during the pandemic promotes positive changes in the subjective well-being. Our results reinforce the need for adopting and maintaining a physical exercise routine during the COVID-19 pandemic as a protective effect on mental health.

Physical Exercise: An Overview of Benefits From Psychological Level to Genetics and Beyond

Any form of physical activity, including exercise, is linked with preventing several diseases including metabolic disorders, cancer, and mood disorders. Beyond benefits, its therapeutic activity is inconclusive in terms of types, intensity, and individual training status, and this could be a major research for prescribing exercise as a therapeutic strategy. Exercise and its myriad forms occupy the space on clinical recommendation, which implies that quantifiable benefits of the same have been proven. Further, the benefits of exercise and its impact have also been found to have a genetic underlying interaction, which has created a niche of personal genomics, wherein apart from diet, an exercise regimen also becomes tailorable for every individual. Many subjective well-being reports highlighted daily exercise to keep mental and general health in excellent conditions, and the uncertainties around it. Thus, adopting an exercise behavior and inculcating it as a routine has been recommended. Further, the kind of benefit that can be extracted out of exercise and training is to a great extent influenced by genetic markers around fat, obesity, hunger, as well as satiety. Genetic markers can also impact the body temperature during exercise, making the entire experience of training either comfortable or unpleasant. Thus, there is an overwhelming amount of scientific evidence that has gathered around the benefits of exercise, which has become a pressing need from the 21st century when the belief in the value of exercise started waning, and that spiked up the era of lifestyle and noncommunicable ailments.

Multimodal Interventions to Improve the Management of Chronic Non-Malignant Pain in Primary Care Using Participatory Research

BACKGROUND

The use of diverse therapies combined with a multidisciplinary approach and prevention initiatives for patients with chronic non-malignant pain (CNMP) can improve health and have a positive impact on psychotropic drug use and the self-management of pain.

PURPOSE

This purpose of this study has been two-fold: to conduct a literature review with a view to selecting best evidence recommendations for CNMP and to prioritize self-care recommendations using a participatory methodology for the analysis and selection of interventions.

METHODS

A qualitative, descriptive, and documentary method based on participatory action research was used.

FINDINGS

Based on the study results, a multimodal psychosocial intervention program has been designed for CNMP that includes psychoeducational therapy, pharmacological therapy, physical exercise, and health assets.

DISCUSSION

The findings are consistent with previous studies underlining the need to invest in resources for the management of CNMP, including strategies for good differential diagnoses and pharmacological treatments combined with non-pharmacological treatments to confer greater well-being for people living with pain who want to participate in their own recovery.

Risk factors for stress among police officers: A systematic literature review

BACKGROUND

Stress is common among police personnel leading to several negative consequences.

OBJECTIVE

We performed a systematic literature review to identify risk factors for stress among police officers.

METHODS

We searched PubMed and Scopus electronic databases through to July 2018 and we conducted this review according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. The Newcastle-Ottawa scale was used for studies quality assessment.

RESULTS

After selection, 29 cross-sectional studies met the inclusion criteria and included in the review. The average quality of studies was low since no study was rated as having low risk of bias, three studies (10.3%) as moderate risk and 26 studies (89.7%) were rated as having high risk of bias. Stress risk factors were summarized in the following categories: demographic characteristics; job characteristics; lifestyle factors; negative coping strategies and negative personality traits.

CONCLUSIONS

Identification of stress risk factors is the first step to create and adopt the appropriate interventions to decrease stress among police personnel. The early identification of police officers at higher risk and the appropriate screening for mental health disorders is crucial to prevent disease and promote quality of life.

Voluntary Wheel Running Partially Attenuates Early Life Stress-Induced Neuroimmune Measures in the Dura and Evoked Migraine-Like Behaviors in Female Mice

Migraine is a complex neurological disorder that affects three times more women than men and can be triggered by endogenous and exogenous factors. Stress is a common migraine trigger and exposure to early life stress increases the likelihood of developing chronic pain disorders later in life. Here, we used our neonatal maternal separation (NMS) model of early life stress to investigate whether female NMS mice have an increased susceptibility to evoked migraine-like behaviors and the potential therapeutic effect of voluntary wheel running. NMS was performed for 3 h/day during the first 3 weeks of life and initial observations were made at 12 weeks of age after voluntary wheel running (Exercise, -Ex) or sedentary behavior (-Sed) for 4 weeks. Mast cell degranulation rates were significantly higher in dura mater from NMS-Sed mice, compared to either naïve-Sed or NMS-Ex mice. Protease activated receptor 2 (PAR2) protein levels in the dura were significantly increased in NMS mice and a significant interaction of NMS and exercise was observed for transient receptor potential ankyrin 1 (TRPA1) protein levels in the dura. Behavioral assessments were performed on adult (>8 weeks of age) naïve and NMS mice that received free access to a running wheel beginning at 4 weeks of age. Facial grimace, paw mechanical withdrawal threshold, and light aversion were measured following direct application of inflammatory soup (IS) onto the dura or intraperitoneal (IP) nitroglycerin (NTG) injection. Dural IS resulted in a significant decrease in forepaw withdrawal threshold in all groups of mice, while exercise significantly increased grimace score across all groups. NTG significantly increased grimace score, particularly in exercised mice. A significant effect of NMS and a significant interaction effect of exercise and NMS were observed on hindpaw sensitivity following NTG injection. Significant light aversion was observed in NMS mice, regardless of exercise, following NTG. Finally, exercise significantly reduced calcitonin gene-related peptide (CGRP) protein level in the dura of NMS and naïve mice. Taken together, these findings suggest that while voluntary wheel running improved some measures in NMS mice that have been associated with increased migraine susceptibility, behavioral outcomes were not impacted or even worsened by exercise.

Early rehabilitation nursing in ICU promotes rehabilitation of patients with respiratory failure treated with invasive mechanical ventilation

OBJECTIVE

This paper aimed at exploring the application value of early rehabilitation nursing (ERN) in intensive care unit (ICU) for nursing patients with respiratory failure (RF) treated with invasive mechanical ventilation (IMV).

METHODS

Admitted to the ICU of our hospital from January 2019 to June 2020, 172 RF patients that was treated with IMV were selected as the research objects. Those in the general group (n=80) received routine nursing in ICU, whereas those in the recovery group (n=92) received ERN on the basis of the general group. The recovery of their vital signs, blood gas functions and pulmonary functions was monitored. Their treatment time in ICU, mechanical ventilation time (MVT), total hospitalization time (THT) and incidence of complications were recorded. Their negative emotions, quality of life (QOL) and nursing satisfaction were assessed.

RESULTS

After intervention, the body temperature, the respiratory rate and the heart rate in the recovery group were lower than those in the general group (P<0.05). The arterial partial pressure of oxygen (PaO₂) and blood oxygen saturation (SpO₂) were remarkably higher in the recovery group, while the arterial partial pressure of carbon dioxide (PaCO₂) was remarkably lower (P<0.05). One-second forced expiratory volume (FEV₁), FEV₁/forced vital capacity (FVC) and FEV₁% were remarkably higher in the recovery group (P<0.05). The treatment time in ICU, the MVT and the THT were remarkably shorter in the recovery group (P<0.05). During intervention, the total incidence of complications was lower in the recovery group (P<0.05). While after intervention, the scores of the Self-rating Anxiety Scale (SAS), the Self-rating Depression Scale (SDS) and the St. George's Respiratory Questionnaire (SGRQ; symptom, activity, impact) were lower in the recovery group, but the nursing satisfaction was remarkably higher (P<0.05).

CONCLUSION

During the treatment of RF patients with IMV, ERN can promote their recovery, reduce the incidence of complications, relieve their negative emotions, and improve their QOL and nursing satisfaction. So, this nursing model is worthy of clinical application.

Migraine and Mood in Children

Migraine is one of the most prevalent headache disorders in children and negatively influences their quality of life. Physical, social, and school functioning are negatively affected. Mood changes are common in migraineurs and may happen before, during, or after a migraine headache. Children with migraine are not exempt from mood swings. The majority of mood changes occur during the prodromal phase, manifesting as a psychobiological response, e.g., difficulty thinking, trouble concentrating, irritability, higher or lower energy, confusion, and depression. A bi-directional relationship between migraine and mood has been proposed, but mechanisms are not clear. Collectively, a maladaptive stress response has been suggested to explain the inability to balance homoeostatic changes when facing various stressors. Recognizing mood changes and monitoring mood patterns in children with migraine, for example, by various apps and so-called mood monitors, is valuable for better management. A multidisciplinary intervention has been recommended to reduce migraine disability, improve coping strategies, and reduce chronification risks in children with migraine. Pharmacological and non-pharmacological strategies are both available and effective. Biofeedback, relaxation, and cognitive-behavioral therapy yield positive outcomes in pediatric migraine. Developing healthy lifestyle habits (diet, exercise, sleep) also seems to improve migraine in this population.

Short-Term Analysis (8 Weeks) of Social Distancing and Isolation on Mental Health and Physical Activity Behavior During COVID-19

Due to the COVID-19 pandemic, cities and states adopted social distancing, social isolation, or quarantine measurements to slow the transmission of the disease. Negative mental health outcomes including depression and anxiety have been associated with social distancing or social isolation. The purpose of the present study was to examine changes in psychological health and physical activity over an 8 week period under social distancing policies during the COVID-19 pandemic. Methods: Ninety (73.3% female; age 32.04 ± 11.33) individuals participated in this study. Qualifying participants answered questions using an online survey regarding their loneliness, depressive symptoms, anxiety symptoms, mood state, and physical activity over four time points each lasting two weeks. Results: Symptoms of depression and state anxiety were increased in the population when compared to nationwide statistics from before the COVID-19 pandemic. Time point 2, ~1 month into social isolation, showed the most significant effects on mental health. During this time point, 100% of the participants showed symptoms of depression. There were no significant changes in physical activity over the 8 weeks. Loneliness, depressive symptoms, fatigue, and mood state were negatively associated with participation in physical activity. Vigor and state anxiety were associated with participation in physical activity. Conclusion: Social isolation and social distancing practices have had a negative effect on depression, anxiety, and mood over time. It appeared that depressive symptoms and total mood disturbance was elevated during time point two. Depressive symptoms were much higher than average compared to previous epidemiological data. Physical activity amount did not change over time but was associated with poor mental health.

Low-Intensity Exercise as a Modifier of Depressive Symptoms and Self-Perceived Stress Level in Women with Metabolic Syndrome

The study aims to determine the impact of low-intensity exercise and psychoeducation on depressive symptoms and self-perceived stress in women with metabolic syndrome (MetS). Seventy-four women (mean age 69.35 ± 7.20) were included in the study. Participants were divided into two groups: those with MetS (n = 33) and those without MetS (n = 41). Subjects participated in low-intensity general-fitness exercise sessions combined with psychoeducation distributed regularly over a 12-week period. Participants completed the Geriatric Depression Scale-15 (GDS) and the Stress Level Questionnaire (SLQ) before and after the intervention. All investigated parameters significantly decreased for the participants with metabolic syndrome after the intervention. The level of GDS in this group decreased by approximately 37% (p < 0.01), and SLQ by around 23% (p < 0.01). Our results suggest, that low-intensity exercise combined with psychoeducation could lower depressive symptoms and stress level in women with MetS. However, the intervention does not lower anthropometric parameter scores.

Interaction between intensity and duration of acute exercise on neuronal activity associated with depression-related behavior in rats

We examined the activities of serotonin (5-HT) neurons in the dorsal raphe nucleus (DRN) and corticotropin-releasing factor (CRF) neurons in the hypothalamic paraventricular nucleus (PVN) during acute treadmill running at different speeds (control, low, high) and durations (15, 30, 60 min) in male Wistar rats using c-Fos/5-HT or CRF immunohistochemistry. We also performed elevated plus maze test (EPM) and forced swim test (FST) after acute treadmill running in rats. Acute treadmill running at low speed, regardless of exercise duration, significantly increased c-Fos expression in 5-HT neurons in the DRN compared with controls, whereas high-speed running significantly activated 5-HT neurons only at 60-min duration. In contrast, c-Fos expression in CRF neurons in the PVN was enhanced in an intensity-dependent manner, regardless of exercise duration. c-Fos expression in 5-HT neurons in the DRN induced by the acute treadmill running for 30 or 60 min, but not 15 min, was positively correlated with the time spent on the open arms in the EPM and was negatively correlated with the immobility time in the FST. These results suggest an interaction between exercise intensity and duration on the antidepressant effects of acute physical exercise.

Mood Responses Associated With COVID-19 Restrictions

The COVID-19 pandemic resulted in more than half the world's population being placed in lockdown to stem the spread of the virus. The severe restrictions imposed in many nations had the potential to significantly influence the physical and psychological well-being of those affected. The aim of the current study was to investigate mood responses during the period of restrictions from March to June, 2020. Mood responses of 1,062 participants (386 male, 676 female) were collected using the Brunel Mood Scale, hosted on the In The Mood website www.moodprofiling.com. The mean pattern of mood responses reflected an inverse iceberg profile, characterized by significantly elevated scores for tension, depression, anger, fatigue, and confusion, and below average scores for vigor; a profile associated with increased risk of mental health issues. Females reported more negative mood scores than males. Participants in the ≤25 age group reported the most negative profiles whereas those in the ≥56 age group reported the least negative profiles. Mood differences related to education status were also evident. Finally, mood scores fluctuated over time, with profiles being most negative during April and June. Overall, results confirmed significant mood disturbance during the period of COVID-19 restrictions, representing increased risk of psychopathology.

The effects of exercise training on hypothalamic-pituitary-adrenal axis reactivity and autonomic response to acute stress-a randomized controlled study

BACKGROUND

Exercise training is suggested to have a stress-buffering effect on physiological reactions to acute stress. The so-called cross-stressor adaptation hypothesis is one of many theories behind the plausible effects, proposing that the attenuated physiological reaction seen in trained individuals in response to acute exercise is also seen when the individual is exposed to acute psychosocial stress. However, few randomized controlled trials (RCT) are available in this field. Therefore, the aim of the present trial was to study the effects of a 6-month aerobic exercise intervention on the physiological response to acute laboratory stress.

METHODS

A two-armed RCT including untrained but healthy individuals aged 20-50 years was conducted. Assessments included a peak oxygen uptake test and a psychosocial stress test (the Trier Social Stress Test). A total of 88 participants went through both baseline and follow-up measures (48 in the intervention group and 40 in the control group) with a similar proportion of women and men (20 women and 28 men in the intervention group and 18 women and 22 men in the control group). Outcome measures were adrenocorticotrophic hormone, cortisol, systolic and diastolic blood pressure, and heart rate responses to acute psychosocial stress.

RESULTS

Oxygen uptake and time-to-exhaustion increased significantly following the intervention, while a decrease was seen in the control group. The analyses showed attenuated responses to acute psychosocial stress for all variables in both groups at follow-up, with no differences between the groups. No correlation was seen between amount of exercise training and reactivity to the stress test. Despite the increased oxygen uptake in the intervention group, no differences were seen between the groups for any of the outcome variables at follow-up.

CONCLUSIONS

In this study, the cross-stressor adaptation hypothesis could not be confirmed. Both groups showed decreased reactions indicating a habituation to the stress test.

The Effect of Aerobic Physical Activity in Adrenaline Level in White Laboratory Rats

Introduction

Physical activity is one important factor in the nervous system of animals, it may affect the structure also the function of the brain. Regular aerobic exercises have a good effect on the whole body and thus improves the sense of well-being.

Aim

The aim of this experiment was to evaluate the effect of aerobic physical activity in white laboratory rats for 21 days.

Methods

The experimental animals used were twenty Wistar rats, divided into 2 groups of 10 animals they were subjected to forced swim test for 21 days for 60-90 min swim. The evaluation of levels of Adrenaline was performed on 1st, 7th, 14th day and on the last day of the experiment day 21 using ELISA kit protocol, also body mass was compared between groups.

Results

Our results showed that inducing aerobic physical activity for 21 days on the rats affects their levels of adrenaline. Comparatively, the control group of rats had significantly higher levels of adrenalin compared with day 21 (p=0.435) but lower compared with day 7 and 14 (p=0.231). There was also a difference in body mass which demonstrates adaptability to the surroundings and better coping with physical stress.

Conclusion

Regular aerobic activity for 21 days, for 60-90 min swim has a positive impact on adrenaline level also this aerobic exercise protocol could have a positive impact on reducing and maintaining body weight, thus preventing overweight.

Physical activity, cardiovascular health and mood state in older adults

Many older adults eat poorly balanced diets and are physically inactive, posing a risk to their cardiovascular and mental health. The benefits of healthful living extend beyond cardiovascular health and disease risk reduction such that physical activity has been shown to positively affect mood state. This was a cross-sectional investigation completed at three senior lunch program sites in Charlotte, NC to assess the status and relationship of nutrition, physical activity patterns, and mood state in older adults, prior to the center offering a new nutritional and physical activity intervention. Some significant relationships between cardiovascular indicators and mood were found.

Physical activity engagement and responses to exercise in plaque psoriasis: a multifactorial investigation of influential factors

Background: Psoriasis may increase the risk of physical inactivity, but few studies have evaluated the etiology.Objective: To identify barriers to and predictors of physical activity in psoriasis.Methods: Twenty individuals with psoriasis (PsO) and 23 controls recorded activity with accelerometers and completed self-paced 20-min treadmill bouts. Questionnaires on self-efficacy for exercise (SEE), pruritus, and dermatology life quality index (DLQI) were completed. Psoriasis severity was measured via body surface area (BSA), psoriasis area and severity index (PASI), and investigator's global assessment (IGA).Results: No differences in moderate-vigorous activity existed between PsO and controls (ANCOVA means: 26 ± 4 versus 27 ± 4 min, p = .802). Relative to controls, PsO selected treadmill speeds that were 13-18% slower and experienced more pruritus while exercising. Among the PsO group, PASI, BSA, IGA, and DLQI showed inverse correlations with vigorous activity (partial rhos= -0.55 to -0.62, p < .05). Likewise, BSA, IGA, DLQI, and pruritus were inversely correlated with footsteps (partial rhos= -0.47 to -0.62, p < .05). SEE was consistently positively correlated with activity levels among PsO (partial rhos ≥0.60 for moderate activity, vigorous activity, and footsteps).Conclusion: Individuals with extensive psoriasis and poorer SEE engage in less vigorous activity and take fewer footsteps. Among other factors, pruritus is a novel explanation.

Ecological momentary assessment of mood and physical activity in people with depression

BACKGROUND

This study aimed to examine temporal associations between physical activity and subsequent mood in people with moderate to severe depression.

METHODS

The study used ecological momentary assessment to associate mood, measured via text messaging twice daily for five days, using a 10-point Likert scale, with objectively measured physical activity (accelerometer data) in people with moderate-to-severe depression. Multilevel regression models were used to explore the relationship between physical activity undertaken at different intensities over the previous one and three hours, and subsequent affect score. A total of 388 paired data points were collected from 43 participants.

RESULTS

There was no association between minutes of moderate-vigorous physical activity in the previous hour and subsequent affect score (which we had hypothesised). However, exploratory analyses found a significant relationship between affect and combined physical activity in the previous hour (β₁ coefficient = 0.023, p = 0.037).

LIMITATIONS

Periods of moderate-vigorous activity were infrequent, reducing the statistical power for analysing associations with this intensity of activity. Only one dimension of mood was sampled.

CONCLUSIONS

The data suggest that, in people with moderate-to-severe depression, time spent engaging in any intensity of physical activity was significantly associated with subsequent mood. Further research is needed to more clearly define the dynamics of the relationship between physical activity and low mood. This will aid identification of optimal prescription criteria for physical activity in people with depression.

Web-Based Intervention Effects on Mild Cognitive Impairment Based on Apolipoprotein E Genotype: Quasi-Experimental Study

BACKGROUND

Apolipoprotein E (APOE) ε4 allele is a major genetic risk factor for Alzheimer disease and mild cognitive impairment (MCI). Computer-based training programs can improve cognitive performance in elderly populations. However, the effects of computer-based interventions on MCI APOE ε4 carriers have never been studied before.

OBJECTIVE

The effects of different web-based interventions and the APOE isoform-specific differences in training outcomes are investigated.

METHODS

Using a quasi-experimental study design, 202 participants with MCI aged 60 years and older took part in three different intervention programs (physical and cognitive [Long-Lasting Memories, or LLM], cognitive [Active Control, or AC], or physical intervention [Physical Training Control, or PTC]) via an innovative information and communication technologies exergaming platform. Participants in each interventional group were subdivided into APOE ε4 carriers and non-APOE ε4 carriers. All participants underwent an extensive neuropsychological evaluation before and after the training, blood tests, and brain imaging.

RESULTS

All interventions resulted in multiple statistically significant cognitive benefits after the intervention. Verbal learning (California Verbal Learning Test: immediate recall test score-LLM: P=.04; AC: P<.001), working memory (digit span forward and backward test scores-AC: P=.03; PTC: P=.02 and P=.006, respectively), and long-term memory (California Verbal Learning Test: delayed recall test score-LLM: P=.02; AC: P=.002; and PTC: P=.02) were improved. There was no statistically significant difference among the intervention effects. APOE ε4 presence moderates intervention effects as the LLM intervention improved only their task-switching processing speed (Trail Making Test, Part B: P=.03) and the PTC intervention improved only the working memory (digit span backward: P=.03). No significant performance alteration was noted for the APOE ε4+ cognitive AC training group.

CONCLUSIONS

None of the applied interventions could be identified as the optimal one; it is suggested, however, that combined cognitive and physical training and physical training via exergaming may be more effective for the high-risk MCI ΑPOE ε4+ subgroup.

The therapeutic potential of exercise for neuropsychiatric diseases: A review

Exercise is known to have a myriad of health benefits. There is much to be learned from the effects of exercise and its potential for prevention, attenuation and treatment of multiple neuropsychiatric diseases and behavioral disorders. Furthermore, recent data and research on exercise benefits with respect to major health crises, such as, that of opioid and general substance use disorders, make it very important to better understand and review the mechanisms of exercise and how it could be utilized for effective treatments or adjunct treatments for these diseases. In addition, mechanisms, epigenetics and sex differences are examined and discussed in terms of future research implications.
