Item type: Item , Cardiorespiratory fitness is associated with lower anger and anxiety and higher emotional resilience(2026) Costa, Thalles Guilarducci; Amaral, Lucas Carrara do; Morais, Naiane Silva; Silva, Wellington Fernando da; Santos, Douglas Assis Teles; Vancini, Rodrigo Luiz; Vieira, Carlos Alexandre; Campos, Mario Hebling; Andrade, Marilia dos Santos; Knechtle, BeatBackground and aims Physical activity is part of the treatment for several mental diseases, including anxiety disorders. However, it is not known whether individuals with higher levels of physical fitness experience lower levels of anxiety or stressful emotions. It is also unknown whether those individuals can better control their emotions in stressful situations. The aim of this study was to examine whether high cardiorespiratory fitness is associated with lower trait levels of anger and anxiety, and whether individuals with different fitness levels show distinct emotional responses to unpleasant visual stimuli. Methods On separate days, 40 healthy young participants completed two sessions. Trait anxiety and anger were assessed during the first session to characterize the participants. The participants self-reported their exercise practice to predict cardiorespiratory fitness (CRF). The participants' anger/anxiety levels were assessed before and after exposure to a 69-picture set of unpleasant or neutral pictures for 30 min. Results Multiple regression analysis showed that maximal oxygen uptake (V̇O2max) (β = −0.241, t = −3.173, 95% confidence interval CI [−0.395; −0.087], p = 0.003) and anger-out (β = 0.333, t = 2.124, 95%CI [0.015; 0.651], p = 0.040) were predictors of changes in anger-state in the unpleasant picture presentation. Individuals with a V̇O2max below average (BA) had a 775% greater risk for changing their classification from intermediate to high anxiety levels compared to above average (AA) individuals (OR = 8.754, 95%CI [1.202; 63.759]). V̇O2max was a predictor of trait anxiety (β = −0.456, t = −3.485, 95%CI [−0.721; −0.191]; p = 0.001). Conclusion CRF is associated with lower levels of trait anxiety and higher resilience in situations of emotional stress.Item type: Item , Quality of life, fatigue, and muscle strength in women with breast cancer undergoing chemotherapy or hormonal therapy: a case-control study(2025) Silva, Naiany Pereira; Marques, Vitor Alves; Ferreira Junior, João Batista; Freitas-Junior, Ruffo; Vieira, Carlos AlexandreBackground: Breast cancer treatments negatively affect women’s physical and emotional well-being due to adverse effects. This study compared the quality of life, fatigue levels, and muscle strength of women with breast cancer undergoing chemotherapy or hormonal therapy with a control group of healthy women. Methods: A case-control study was conducted including women aged 45 to 65 years diagnosed with breast cancer between October 2021 and August 2022 at the Hospital das Clínicas de Goiânia, Brazil. Approximately one age-matched control was selected from the general population for every 2.2 cases. Quality of life was assessed using the EORTC QLQ-BR23, fatigue with the FACT B + 4, and muscle strength through handgrip tests. Results: Ninety-five participants were included (65 cases, 30 controls). Among cases, 40% (n = 26) were undergoing chemotherapy and 60% (n = 39) hormonal therapy. Quality-of-life domains such as general symptoms, side effects, and arm and chest symptoms were worse among treated cases compared to controls (p < 0.01 for all). No significant differences were observed between treatment groups (p > 0.05). Fatigue levels were higher among cases compared to controls in domains such as physical and social well-being, general fatigue, cancer- related fatigue, and breast cancer-related fatigue (p < 0.01, p = 0.05, p < 0.01, p < 0.01, p < 0.01, respectively), with no significant differences between treatment groups (p > 0.05). Handgrip strength was lower in cases treated with hormonal therapy on the right side compared to controls (-5.0; 95% CI: -7.69 to -2.31; effect size: -0.49) which represents a moderate magnitude effect. On the left side, both treatment groups showed reduced strength compared to controls (-5.1; 95% CI: -7.99 to -2.21; -5.9; 95% CI: -8.51 to -3.29; effect sizes: -0.93 and -1.04, respectively) indicating effects of large magnitude, which may suggest possible clinical relevance. No significant differences were observed between treatment groups (p > 0.05). Conclusion: Differences in quality of life, fatigue, and muscle strength were observed between women undergoing treatment and those who were healthy, with no distinction between types of treatment.Item type: Item , Physical activity levels of women with breast cancer during treatment: a case-control study(2025) Silva, Naiany Pereira; Marques, Vitor Alves; Ferreira Júnior, João Batista; Vieira, Carlos AlexandreIntroduction: Maintaining or increasing physical activity levels after a breast cancer diagnosis may contribute to reducing the risk of disease recurrence and improving survival among affected women. Objective: To compare the physical activity levels of women with breast cancer to those of healthy women of the same age group. Methods: A case-control study was conducted between October 2021 and August 2022, including postmenopausal women aged 45 to 65 years. Women with breast cancer were recruited from the Goiânia Clinical Hospital, Goiás, Brazil. Approximately one age-matched control was selected from the general population for every 2.2 cases. Physical activity levels were assessed using the short version of the International Physical Activity Questionnaire. The final sam-ple comprised 95 women, including 65 cases and 30 controls. Results: Among the cases, 40% (n = 26) were undergoing chemotherapy and 60% (n = 39) were receiving hormone therapy. Results: In the overall analysis, women with breast cancer presented significantly lower physical activity levels compared to the control group (median: 198 MET-min/week; IQR: 0.00 – 547 vs. 606; IQR: 57.75 – 1062; p = 0.008). In the subgroup analysis, a statistically significant difference in physical activity levels was observed among the groups undergoing chemotherapy, hormone therapy, and the control group (p = 0.009). Conclusion: Women with breast cancer exhibit lower levels of physical activity compared to healthy women of the same age group. Randomized clinical trials and epidemiological studies are needed to establish causality.Item type: Item , Do team sports have positive effects on anxiety levels and mood disorders? A systematic review protocol(2026) Rocha, Augusto Cezar Rodrigues; Noll, Matias; Vieira, Carlos Alexandre; Clemente, Filipe Manuel; Rodrigues, Marcelo Couto Jorge; Correa, Jose Carlos Pontes; Lira, Claudio Andre Barbosa de; Weiss, Katja; Rosemann, Thomas; Knechte, Beat; Campos, Mário Hebling; Sá Filho, Alberto Souza de; Costa, Gustavo de Conti TeixeiraBackground Mental disorders, particularly anxiety and mood disorders, significantly impair individuals’ ability to perform daily activities, potentially leading to sedentary behavior and increasing the risk of non-communicable diseases such as diabetes, cancer, and obesity. Physical activity plays a crucial role in supporting mental health, and team sports represent a promising intervention strategy. Therefore, the aim of this systematic review is to evaluate the impact of team sports practice on anxiety and mood disorders. Furthermore, it will analyze how different modalities of team sports contribute to mental health improvements and identify gaps in the current literature to guide future research directions. Methods This systematic review will be reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols (PRISMA-P) guidelines and is registered in PROSPERO (CRD420251121611). A comprehensive search will be carried out across four electronic databases (PubMed, Embase, Web of Science, and Scopus) with no restrictions on language or publication date. Two independent reviewers will screen titles and abstracts using predefined eligibility criteria and extract data with standardized tables. A third independent reviewer will resolve any disagreements. Extracted data will include publication title, authors, year, assessment tools for anxiety and mood disorders, type of intervention, and primary outcomes related to the effects of team sports on these disorders. Risk of bias will be assessed using the Cochrane Risk of Bias tool (RoB 2.0). Data will be synthesized using a random-effects meta-analysis (DerSimonian-Laird) when at least two sufficiently homogeneous studies report the same outcome. Continuous outcomes will be pooled as mean differences (same scale) or standardized mean differences (different instruments). Statistical heterogeneity will be assessed using Cochran’s Q and the I2 statistic. If heterogeneity is high (I2 > 75%) or if pooling is not feasible, findings will be summarized narratively, with planned subgroup and sensitivity analyses. The certainty of evidence will be assessed using GRADE. Discussion This systematic review is expected to provide comprehensive evidence on the potential effects of team sports participation on anxiety and mood disorders. By synthesizing findings from randomized controlled trial, the review aims to clarify the extent to which engaging in team sports may contribute to mental health promotion and symptom reduction. The results may inform clinical practice, guide the design of community-based interventions, and support policymakers in developing evidence-based strategies that use team sports as a non-pharmacological approach to improve psychological well-being.Item type: Item , Association of I/D polymorphism in the ACE gene and the susceptibility of patients to diabetic neuropathy(2025) Menezes, Georgia Silva; Paiva, Pedro Luiz de; Santos, Kamilla de Faria; Reis, Angela Adamski da Silva; Santos, Rodrigo da SilvaWe conducted a systematic review and meta-analysis to evaluate the association between polymorphisms in the ACE and ACE2 genes and the development of diabetic neuropathy (DN). Methods: We searched six databases (NCBI/PubMed, MEDLINE, Cochrane Library, Virtual Health Library, Scielo, and Embase) as well as grey literature (Google Scholar and citations). Two independent reviewers selected the articles according to predefined inclusion and exclusion criteria. Results: The systematic literature search identified 114 records across the databases. At the end of the selection process, 5 studies were included in the qualitative analysis, and 4 studies were included in the quantitative analysis. All included studies were case-control studies conducted in Iraqi, Pakistani, and Turkish populations. Conclusion: According to the meta-analysis, the ID+DD genotypes of the ACE gene I/D polymorphism are associated with an increased risk of developing DN (OR = 1.43, CI = 1.01–2.03, p = 0.0464). Our analysis also suggests that the D allele is a risk marker for DN (OR = 1.42, CI = 1.19–1.68, p < 0.0001), with similar findings previously reported. Further observational studies in diverse populations are needed to confirm this association.
