COVID-19 pandemic raised concerns about the effects of stress on mental health and sleep deficiency. Cognitive behavioural therapy for insomnia (CBT-I) has been shown to improve sleep quality and insomnia severity, as well as anxiety and depression, and may be protective during times of stress, including the COVID-19 pandemic. The aim of this study was to examine changes in sleep, sleep-related cognitions, stress, anxiety, and depression among people with heart failure (HF). This study was a randomised controlled trial of the effects of CBT-I compared with HF self-management education (attention-control condition), the “HeartSleep Study.” Results showed that improvements in insomnia severity, sleep quality, latency, and efficiency, sleep-related cognitions and stress, anxiety, and depression after participation in CBT-I or an HF self-management class were sustained during the pandemic. Authors conclude that their findings confirm the clinical benefits of CBT-I for people with HF and comorbidities and also suggest the potential benefits of HF self-management education.
Abstract
BACKGROUND The COVID-19 pandemic raised concerns about the effects of stress on sleep and mental health, particularly among people with chronic conditions, including people with heart failure (HF). OBJECTIVE The aim of this study was to examine changes in sleep, sleep-related cognitions, stress, anxiety, and depression among people with HF who participated in a randomized controlled trial of cognitive behavioral therapy for insomnia before the COVID-19 pandemic. METHODS Participants self-reported sleep characteristics, symptoms, mood, and stress at baseline, 6 months after cognitive behavioral therapy for insomnia or HF self-management education (attention control), and during the pandemic. RESULTS The sample included 112 participants (mean age, 63 ± 12.9 years; 47% women; 13% Black; 68% New York Heart Association class II or III). Statistically significant improvements in sleep, stress, mood, and symptoms that occurred 6 months post treatment were sustained during the pandemic. CONCLUSIONS Improving sleep and symptoms among people with HF may improve coping during stressful events, and cognitive behavioral therapy for insomnia may be protective.

Plain language summary
Sexual dysfunction has been shown to be closely associated with irritable bowel syndrome (IBS). Individuals with these dysfunctions have been shown to have reduced quality of life (QoL), however further research is warranted. This cross-sectional study aimed to determine QoL in 51 women with IBS and sexual dysfunction compared to 54 women without these disorders. The results showed that the presence of IBS did not increase the occurrence of sexual dysfunction. However, the presence of both disorders did decrease QoL and affect physical function, general health, vitality, social function, emotion, and mental health. These effects were especially prominent in women who suffer from the constipation IBS subtype than the unclassified IBS subtype. It was concluded that sexual dysfunction affects the QoL of women with IBS. This study could be used by healthcare professionals to understand that women with IBS may need to be assessed for sexual dysfunction and if found may need additional support to improve their quality of life.
Abstract
BACKGROUND Irritable bowel syndrome (IBS) and sexual dysfunction (SxD) lowers quality of life (QOL) separately, but the effect of their overlap in unselected populations has not been studied. OBJECTIVE To evaluate the QOL of IBS women with and without SxD and compare it with controls. METHODS In this cross-sectional assessment, we studied 51 IBS women (Rome IV criteria) and 54 controls. SxD was determined using the female sexual function index questionnaire. QOL was evaluated by the Short Form 36 (SF-36) and IBS-QOL questionnaires. RESULTS SxD prevalence was similar between IBS women (39.22%) and controls (38.89%). Compared with other groups, IBS patients with SxD showed lower scores in all domains as well as in the physical, mental summaries of the SF-36 and almost all domains (except for body image, food avoidance, and social reaction compared with IBS patients without SxD) and the total score of IBS-QOL. CONCLUSIONS These findings show that SxD worsens both general and specific QOL of women with IBS. The consideration of SxD in patients with IBS will allow us to make a more effective diagnostic and therapeutic approach. Clinical trial registry in Mexico City General Hospital: DI/19/107/03/080.

Plain language summary
The World Health Organization defines infertility as regular unprotected sexual intercourse without achieving conception within a year. In recent years, there has been a growing demand for functional, objective parameters reflecting fertility status more clearly than classical parameters. Of these, sperm DNA fragmentation (SDF) and the DNA fragmentation index – denoting the percentage of sperm with damaged DNA – seem to be of utmost importance. The aim of this study was to investigate all risk factors that may potentially be increasing SDF. This study is a systematic review and meta-analysis of one hundred and ninety articles. The earliest studies were published in 2003, and the latest in 2021. Results show that several modifiable risk factors negatively affect SDF, namely; a. health conditions: varicocele [when veins become enlarged inside the pouch of skin that holds the testicles] and impaired glucose tolerance, b. infections: Chlamydia, c. malignancies: testicular tumours, and d. lifestyle factors: smoking, alcohol consumption and body mass index. Authors conclude that several lifestyle-, environmental-, and additional health factors are associated with increased SDF.
Abstract
INTRODUCTION Infertility affects one in every six couples in developed countries, and approximately 50% is of male origin. In 2021, sperm DNA fragmentation (SDF) testing became an evidence-based test for fertility evaluations depicting fertility more clearly than standard semen parameters. Therefore, we aimed to summarize the potential prognostic factors of a higher SDF. METHODS We conducted a systematic search in three medical databases and included studies investigating any risk factors for SDF values. We calculated mean differences (MD) in SDF with 95% confidence interval (CI) for exposed and non-exposed individuals. RESULTS We included 190 studies in our analysis. In the group of associated health conditions, varicocele (MD = 13.62%, CI: 9.39-17.84) and impaired glucose tolerance (MD = 13.75%, CI: 6.99-20.51) had the most significant increase in SDF. Among malignancies, testicular tumors had the highest impact, with a maximum of MD = 11.3% (CI: 7.84-14.76). Among infections, the overall effects of both Chlamydia and HPV were negligible. Of lifestyle factors, smoking had the most disruptive effect on SDF - an increase of 9.19% (CI: 4.33-14.06). Different periods of sexual abstinence did not show significant variations in SDF values. Age seemed to have a more drastic effect on SDF from age 50 onwards, with a mean difference of 12.58% (CI: 7.31-17.86). Pollution also had a detrimental effect - 9.68% (CI: 6.85-12.52). CONCLUSION Of the above risk factors, varicocele, impaired glucose tolerance, testicular tumors, smoking, pollution, and paternal age of over 50 were associated with the highest SDF.

Plain language summary
Medical students commonly experience anxiety, depression, burnout and emotional discomfort due to the pressures of medical school. This randomised, controlled study of 362 medical students at Italian Universities evaluated the effectiveness of a 5-week online mindfulness-based intervention (MBI), consisting of an introductory session, 8 sessions of 35 min integral meditation and 10 min yoga, and one dietary advice/question and answer session with a nutritionist. The control group received no intervention. Effectiveness was measured through a variety of validated questionnaires for perceived stress, anxiety, wellbeing, emotional health, resilience and cognition. Overall, at baseline, participants of this study fared worse for stress than other studies had shown for general populations. The MBI was effective in improving perceived stress, mental wellbeing, emotional regulation, resilience, tendency to mind-wandering, ability to maintain attention and overall distress, although effect sizes for all outcomes were small. No statistically significant effect was seen for the anxiety rating. Interestingly, two cohorts were included in this study and whilst one benefitted from the programme, the other did not, one explanation of which may be that they were done during different phases of the COVID pandemic. The authors conclude that adopting MBI may help improve students’ wellbeing.
Abstract
Pressures and responsibilities of medical school put a strain on medical student's personal wellbeing, leading among all to high rates of anxiety, emotional discomfort and stress. In this work we evaluated the effectiveness of a comprehensive Mindfulness-Based Intervention (MBI) in reducing this load. The intervention comprised 10 twice-a-week Integral Meditation classes, dietary advice, and brief yoga sessions. We performed a randomized trial on two cohort of medical students from Italian universities: 239 in cohort 1 (106 treated and 133 controls), and 123 in cohort 2 (68 treated and 55 control) for a total sample of 362 students. Nine questionnaires for evaluating the effectiveness of our intervention on stress (PSS), state anxiety (STAIX-1), well-being (WEMWBS), mind-wandering (MW-S), overall distress (PANAS), emotion regulation (DERS), resilience (RS-14), and attentional control (ACS-C and ACS-D) were collected both pre and post intervention. Linear mixed effect models were run on the whole sample showing that, after multiple testing correction, our intervention was effective in reducing perceived stress (β = - 2.57 [- 4.02; - 1.12], p = 0.004), improving mental well-being (β = 2.82 [1.02; 4.63], p = 0.008) and emotional regulation (β = - 8.24 [- 12.98; - 3.51], p = 0.004), resilience (β = 3.79 [1.32; 6.26], p = 0.008), reducing the tendency to wander with the mind (β = - 0.70 [- 0.99; - 0.39], p = 0.0001), ameliorating the ability to maintain attention (AC-S (β = - 0.23 [- 0.44; - 0.02], p = 0.04) and AC-D (β = - 0.19 [- 0.36; - 0.01], p = 0.04)), and the overall distress (β = 1.84 [0.45; 3.23], p = 0.02).

Plain language summary
The International Headache Society defines chronic daily headache (CDH) as headaches occurring on 15 or more days in a month for at least three months. Many pharmacological treatments are available to minimize the functional disability caused by headaches. However, meditation-based mindfulness techniques have gained popularity in recent years. The main aim of this study was to determine the efficacy of mindfulness-based cognitive therapy (MBCT) and mindfulness-based stress reduction (MBSR) in improving headache frequency, duration, and intensity in patients suffering from chronic headaches. This study is an updated systematic review and meta-analysis which included 10 full-text articles (4 from previous meta-analysis and 6 recently published). Results provide limited evidence that MBSR/MBCT intervention may be effective in reducing the frequency, duration, and pain intensity of headaches, in patients with chronic headaches including tension-type and migraine compared with the usual care but it demonstrated a significant difference between groups in achieving mindfulness. Authors conclude that since their findings are inconclusive, MBSR/MBCT interventions for the treatment of migraine and/or tension-type headaches cannot be recommended.
Abstract
Background: Mindfulness-based stress reduction/cognitive therapy has attained popularity as an adjunctive treatment for a plethora of medical and psychiatric conditions, however, its impact on chronic headaches is inconclusive. This review aims to assess the impact of MBSR/MBCT in alleviating the symptoms of chronic headaches. Data sources and data selection: PubMed and Cochrane CENTRAL were searched from inception till 1st May 2021. Randomized Control Trials evaluating mindfulness-based stress reduction/cognitive therapy with either passive comparators (usual care) or active comparators (e.g., Health education or cognitive behavioral therapy) for chronic headaches (Migraine, Tension-type, or cluster headaches), which evaluated either headache frequency, pain intensity or headache duration as primary outcome were eligible for inclusion. The Risk of Bias was evaluated using the Cochrane Collaboration's Risk of Bias Tool. Results: A total of ten Randomized Controlled Trials (five on migraine; three on tension-type; two with mixed samples) were evaluated. In comparison to usual care, mindfulness-based stress reduction/cognitive therapy did not illustrate significant changes in headache frequency (MD = -0.14; 95% CI -1.26 to 0.97; P = 0.80; Moderate Certainty), headache duration (MD = -0.27; 95% CI -3.51 to 2.97, P = 0.87; Low Certainty) or pain intensity (MD = -0.19; 95% CI -0.46 to 0.07; P = 0.15; Moderate Certainty). Conclusion: The results found are insignificant for the three primary outcomes, which may be due to the low number of participants and often a high or unclear risk of bias in the randomized control trials included. Perhaps more aggressive clinical trials with a larger sample size effectively demonstrate differences in outcomes before and after therapy for MBSR/MBCT could provide a more significant change.

Plain language summary
Dynamic communication occurs between the gut microbiota and the central nervous system along multiple physiological pathways. Stress increases glucocorticoid production and activation of the hypothalamic–pituitary–adrenal axis, affecting immunological function and neuronal changes. The aim of this study was to investigate whether supplementation with the probiotic Lactobacillus rhamnosus HN001 could reduce symptoms of stress and anxiety and improve psychological wellbeing in nurses working during the COVID19 pandemic. This study was a large double-blind, placebo-controlled randomised trial of probiotic supplementation with two parallel arms and a ratio of allocation to probiotic or placebo of 1:1. Results showed that following the intervention, stress, anxiety, and psychological wellbeing were not significantly different between nurses supplemented with the probiotic and those who received the placebo. Furthermore, the average number of days per week that nurses reported symptoms of cold or flu-like illness did not significantly differ between the probiotic and placebo supplemented groups. Authors conclude that there weren’t significant differences in outcomes between the probiotic and placebo groups.
Abstract
Animal studies demonstrate how the gut microbiota influence psychological health and immunity to viral infections through their actions along multiple dynamic pathways in the body. Considerable interest exists in probiotics to reduce stress and illness symptoms through beneficial effects in the gut, but translating pre-clinical evidence from animal models into humans remains challenging. We conducted a large trial in nurses working during the 2020 COVID19 pandemic year to establish whether daily ingestion of the probiotic Lactobacillus rhamnosus HN001 reduced perceived stress and the number of days participants reported symptoms of a viral illness. Our results showed no significant difference in perceived stress or the average number of illness days between probiotic supplemented nurses and the placebo group. Stress and viral illness symptoms reduced during the study for all participants, a trajectory likely influenced by societal-level factors. The powerful effect of a well-managed public health response to the COVID19 pandemic and the elimination of COVID19 from the community in 2020 may have altered the trajectory of stress levels and reduced circulating viral infections making it difficult to detect any effect of probiotic supplementation. Our study highlights the challenge in controlling environmental factors in human trials.

Plain language summary
The relationship between type 2 diabetes mellitus and male hypogonadism is well known, whereas the impact of type 1 diabetes mellitus (DM1) on male fertility and testis functions has been less studied. The aim of this study was to systematically review and discuss the available evidence evaluating paternity rate, male gonadal axis, and sperm parameters in men with DM1. This study is a systematic review and meta-analysis of fourteen studies. Results show: - reduced fertility potential in patients with DM1, as they have a lower number of children compared with unaffected population. In fact, the rate of children is statistically significantly lower among men who had been diagnosed with DM1 at an earlier age, according to a longer duration of the disease. - that men with DM1, compared with controls, have significantly lower normal sperm morphology, progressive motility and a trend toward a reduced semen volume, without difference in total sperm count and concentration. Authors conclude that DM1 might impair reproductive health at different levels, including functional sperm alterations definitively leading to reduced fertility rate in these patients.
Abstract
BACKGROUND Some evidence suggests that diabetes mellitus type 1 (DM1) could affect male fertility, gonadal axis, semen parameters, and spermatogenesis because of effects of hyperglycemia and insulin deficiency. Anyhow, the exact impact of DM1 on male fertility is unclear. OBJECTIVES To review the studies evaluating paternity rate, male gonadal axis, and semen parameters in men with DM1. MATERIALS AND METHODS A review of relevant literature from January 1980 to December 2020 was performed. Only studies published in English reporting data on fatherhood (rate of children by natural fertility), hormonal and seminal parameters were included. Out of 14 retrieved articles, the eight studies evaluating semen parameters were meta-analyzed. RESULTS The rate of children (four studies) was lower than controls among men affected by DM1, especially in men with a longer duration of disease. The data of gonadal hormonal profile in DM1 men (six studies) are very heterogeneous and a neutral effect of DM1 or a condition of subclinical hypogonadism could not be concluded. Meta-analysis showed that men with DM1 (n = 380), compared with controls (n = 434), have significantly lower normal sperm morphology [-0.36% (-0.66; -0.06), p < 0.05, six studies] and sperm progressive motility [33.62% (-39.13; -28.11), p < 0.001, two studies] and a trend toward a lower seminal volume [-0.51 (-1.03; 0.02), p = 0.06, eight studies], without difference in total sperm count and concentration. Data on scrotal ultrasound and sperm DNA fragmentation are too few. No study evaluated other factors of male infertility, such as transrectal ultrasound, semen infections, sperm auto-antibodies, and retrograde ejaculation. DISCUSSION DM1 might impair male fertility and testis functions (endocrine, spermatogenesis), but definition of its actual impact needs further studies. CONCLUSION Men with DM1 should be evaluated with a complete hormonal, seminal, and ultrasound workup to better define their fertility potential and need for follow up of testis functions.

Plain language summary
Children with chronic diseases are more likely to suffer emotional-behavioural problems than healthy children, which can also impact the family. Sandplay has successfully been used as a therapy in children with autism spectrum disorder and this randomised control trial aimed to determine the effect of sandplay therapy in 62 children with chronic diseases and their caregivers. The results showed that sandplay reduced anxiety, depression, withdrawal and social behavioural problems and improved behaviour in children with chronic diseases. Depression and anxiety were also improved in the caregivers of those children who participated in sandplay. It was concluded that sandplay therapy is an effective clinical tool to improve several psychological domains in children with chronic diseases.
Abstract
PURPOSE Children with chronic diseases exhibit a higher incidence of emotional-behavioural problems. Though sandplay therapy is a universally recognized psychological treatment method, experimental evidence for this form of therapy is lacking. Our aims were to examine the effectiveness of sandplay therapy in reducing emotional and behavioural problems in school-age children with chronic diseases as well as anxiety and depression in their caregivers. DESIGN AND METHODS A total of 60 children and their caregivers were enrolled in the present study between January and October 2019. A randomized controlled trial was conducted at the Children's Hospital of Chongqing Medical University, China. Participants were divided into an intervention and a control group. Both groups received regular treatment, and the intervention group received additional sandplay therapy. Four behavioural rating scales were used to evaluate the differences between the two groups. The children's scores on the Child Behavior Checklist (CBCL), Eysenck Personality Questionnaire (EPQ), Self-Rating Anxiety Scale (SAS) and Self-Rating Depression Scale (SDS) before and after the intervention were compared using the Mann-Whitney test. The Wilcoxon signed rank test was also employed to compare the median results before and after treatment. RESULTS The total scores for CBCL, anxiety and depression, withdrawal, and social behavioural problems for children in the intervention group were all lower than the corresponding scores for those in the control group (p < .05). The EPQ scores for emotional stability and psychosis in the intervention group were both lower than those in the control group (p < .05). The SAS and SDS scores for the caregivers of children in the intervention group were also lower than the corresponding scores for those in the control group (p < .05). CONCLUSION Sandplay therapy can reduce anxiety, withdrawal, and social behavioural problems in school-age children with chronic diseases, as well as relieve anxiety and depression symptoms in their caregivers. Our study provided evidence for the clinical application of sandplay therapy and highlights the importance of offering and integrating psychological treatment in clinical nursing care.

Plain language summary
Mindfulness-based stress reduction (MBSR), a standardized mind-body treatment that teaches momentary awareness with decreased sensory percept judgment, is associated with improvements in many chronic pain conditions. Mindfulness may be particularly helpful for migraine, as it diminishes affective responses to stress, the most common migraine trigger. This study is a double-blinded, randomized clinical trial of MBSR vs headache education for adults with migraine. The study enrolled 96 participants out of which 89 participants attended at least 1 class and completed at least 1 headache log (MBSR, 45; headache education, 44) across 7 cohorts. Participants were randomly assigned to one of the two arms. Results indicate that participants in both groups demonstrated a reduction of migraine days per month from baseline at 12 weeks. Furthermore, both groups sustained reductions in frequency of migraine and headache without group differences. Compared with headache education, MBSR participants had improvements in headache-related disability, quality of life, depression scores, self-efficacy, pain catastrophizing, and decreased experimentally induced pain intensity and unpleasantness out to 36 weeks. Authors conclude that mindfulness may help treat the total burden of migraine. However, a larger, more definitive study is needed to understand the impact of mindfulness on migraine.
Abstract
Importance: Migraine is the second leading cause of disability worldwide. Most patients with migraine discontinue medications due to inefficacy or adverse effects. Mindfulness-based stress reduction (MBSR) may provide benefit. Objective: To determine if MBSR improves migraine outcomes and affective/cognitive processes compared with headache education. Design, Setting, and Participants: This randomized clinical trial of MBSR vs headache education included 89 adults who experienced between 4 and 20 migraine days per month. There was blinding of participants (to active vs comparator group assignments) and principal investigators/data analysts (to group assignment). Interventions: Participants underwent MBSR (standardized training in mindfulness/yoga) or headache education (migraine information) delivered in groups that met for 2 hours each week for 8 weeks. Main Outcomes and Measures: The primary outcome was change in migraine day frequency (baseline to 12 weeks). Secondary outcomes were changes in disability, quality of life, self-efficacy, pain catastrophizing, depression scores, and experimentally induced pain intensity and unpleasantness (baseline to 12, 24, and 36 weeks). Results: Most participants were female (n = 82, 92%), with a mean (SD) age of 43.9 (13.0) years, and had a mean (SD) of 7.3 (2.7) migraine days per month and high disability (Headache Impact Test-6: 63.5 [5.7]), attended class (median attendance, 7 of 8 classes), and followed up through 36 weeks (33 of 45 [73%] of the MBSR group and 32 of 44 [73%] of the headache education group). Participants in both groups had fewer migraine days at 12 weeks (MBSR: -1.6 migraine days per month; 95% CI, -0.7 to -2.5; headache education: -2.0 migraine days per month; 95% CI, -1.1 to -2.9), without group differences (P = .50). Compared with those who participated in headache education, those who participated in MBSR had improvements from baseline at all follow-up time points (reported in terms of point estimates of effect differences between groups) on measures of disability (5.92; 95% CI, 2.8-9.0; P < .001), quality of life (5.1; 95% CI, 1.2-8.9; P = .01), self-efficacy (8.2; 95% CI, 0.3-16.1; P = .04), pain catastrophizing (5.8; 95% CI, 2.9-8.8; P < .001), depression scores (1.6; 95% CI, 0.4-2.7; P = .008), and decreased experimentally induced pain intensity and unpleasantness (MBSR group: 36.3% [95% CI, 12.3% to 60.3%] decrease in intensity and 30.4% [95% CI, 9.9% to 49.4%] decrease in unpleasantness; headache education group: 13.5% [95% CI, -9.9% to 36.8%] increase in intensity and an 11.2% [95% CI, -8.9% to 31.2%] increase in unpleasantness; P = .004 for intensity and .005 for unpleasantness, at 36 weeks). One reported adverse event was deemed unrelated to study protocol. Conclusions and Relevance: Mindfulness-based stress reduction did not improve migraine frequency more than headache education, as both groups had similar decreases; however, MBSR improved disability, quality of life, self-efficacy, pain catastrophizing, and depression out to 36 weeks, with decreased experimentally induced pain suggesting a potential shift in pain appraisal. In conclusion, MBSR may help treat total migraine burden, but a larger, more definitive study is needed to further investigate these results.

Plain language summary
Synbiotic, a mixture of prebiotics and probiotics, is known to improve neurotransmitter interactions, immune, inflammatory, and stress responses by modulating the gut microbial composition. It is also believed that physical activity plays an important role in the modulation of immune function and stress response. The purpose of this triple-blinded, randomized, placebo-controlled pilot study was to evaluate the health benefits of symbiotic intervention in fourteen sedentary students and thirteen soccer players, especially in terms of improving immunophysiological and metabolic parameters. The 300mg of symbiotic intervention contained Bifidobacterium lactis CBP-001010, Lactobacillus rhamnosus CNCM I-4036, Bifidobacterium longum ES1(109 colony-forming unit), and fructooligosaccharides (200 mg) plus 1.5 mg of zinc, 8.25 µg of selenium, 0.75 µg of vitamin, and maltodextrin. Following a one-month intervention with synbiotic formulation, soccer players showed improvements in anxiety, sleep quality and stress, a slight reduction in proinflammatory cytokine IL-1β, an exercise-induced significant increase in dopamine and a slight elevation of corticotropin-releasing hormone. For confirmation of results of this pilot study and to assess more significant effects of symbiotic intervention in athletes as well as in the general population, longer-term robust studies are required. The findings of this study can help healthcare professionals understand the extensive health benefits of synbiotic intervention and its relationship to physical activity.
Abstract
The main objective of this research was to carry out an experimental study, triple-blind, on the possible immunophysiological effects of a nutritional supplement (synbiotic, Gasteel Plus®, Heel España S.A.U.), containing a mixture of probiotic strains, such as Bifidobacterium lactis CBP-001010, Lactobacillus rhamnosus CNCM I-4036, and Bifidobacterium longum ES1, as well as the prebiotic fructooligosaccharides, on both professional athletes and sedentary people. The effects on some inflammatory/immune (IL-1β, IL-10, and immunoglobulin A) and stress (epinephrine, norepinephrine, dopamine, serotonin, corticotropin-releasing hormone (CRH), Adrenocorticotropic hormone (ACTH), and cortisol) biomarkers were evaluated, determined by flow cytometer and ELISA. The effects on metabolic profile and physical activity, as well as on various parameters that could affect physical and mental health, were also evaluated via the use of accelerometry and validated questionnaires. The participants were professional soccer players in the Second Division B of the Spanish League and sedentary students of the same sex and age range. Both study groups were randomly divided into two groups: a control group-administered with placebo, and an experimental group-administered with the synbiotic. Each participant was evaluated at baseline, as well as after the intervention, which lasted one month. Only in the athlete group did the synbiotic intervention clearly improve objective physical activity and sleep quality, as well as perceived general health, stress, and anxiety levels. Furthermore, the synbiotic induced an immunophysiological bioregulatory effect, depending on the basal situation of each experimental group, particularly in the systemic levels of IL-1β (increased significantly only in the sedentary group), CRH (decreased significantly only in the sedentary group), and dopamine (increased significantly only in the athlete group). There were no significant differences between groups in the levels of immunoglobulin A or in the metabolic profile as a result of the intervention. It is concluded that synbiotic nutritional supplements can improve anxiety, stress, and sleep quality, particularly in sportspeople, which appears to be linked to an improved immuno-neuroendocrine response in which IL-1β, CRH, and dopamine are clearly involved.
