Association between the practice of fitness-related exercises and body image dissatisfaction in adolescents from Curitiba (PR), Brazil / Associação entre a prática de exercícios físicos relacionados ao fitness e insatisfação com a imagem corporal em adolescentes de Curitiba (PR), Brasil

ABSTRACT Objective: The aim of this study was to analyze the association between participation in fitness-related exercises (FRE) and body image dissatisfaction (BID) in adolescents and evaluate the interaction between physical exercise and nutritional status in this association. Methods: A cross-sectional study was conducted in 2015 involving 799 adolescents (10-16 years old) from 14 public schools in Curitiba (PR), Brazil. BID was assessed using the Body Shape Questionnaire and the Silhouette Scale. The FRE was classified as "does not practice," "practices ≤300 min/week," and "practices >300 min/week" by the Physical Activity Questionnaire for Adolescents. Poisson and multinomial logistic regressions, adjusted for sex, sexual maturation, and nutritional status analyzed the association of FRE and BID. Results: The BID prevalence was 28.3%; 52.4% of the adolescents wanted to reduce their silhouettes; and 48.7% did not practice FRE. Adolescents who practiced FRE >300 min/week had a 28% higher prevalence for some level of BID (PR 1.28; 95%CI 1.08-1.52) and a 46% lower chance of wanting to reduce silhouettes (OR 0.54; 95%CI 0.35-0.82), compared to nonpractitioners. There was no interaction between FRE and nutritional status in association with BID. Conclusions: The adolescents who practice FRE >300 min/week are likely to have some level of BID and are less likely to report the desire to increase their silhouettes, regardless of their nutritional status.

RESUMO Objetivo: Analisar a associação entre a participação em exercícios físicos relacionados ao fitness (EFRF) e a insatisfação com a imagem corporal (IIC) em adolescentes e avaliar a interação entre os exercícios físicos e o estado nutricional nesta associação. Métodos: Estudo transversal realizado em 2015 com 799 adolescentes (10 a 16 anos) de 14 escolas públicas de Curitiba (PR), Brasil. A IIC foi avaliada por meio do Body Shape Questionnaire e da Escala de Silhuetas. A participação em EFRF foi avaliada pelo Questionário de Atividade Física para Adolescentes e classificada em "não pratica", "pratica ≤300 minutos/semana" e "pratica >300 minutos/semana". As regressões de Poisson e logística multinomial, ajustadas por sexo, maturação sexual e estado nutricional, analisaram a associação entre EFRF e IIC. Resultados: A prevalência de IIC foi de 28,3%; 52,4% dos adolescentes queriam reduzir a silhueta e 48,7% não praticavam a EFRF. Adolescentes que praticavam EFRF >300 minutos/semana tiveram prevalência 28% maior para algum nível de IIC (razão de prevalência — RP 1,28; intervalo de confiança de 95% — IC95% 1,08-1,52) e chance 46% menor de querer reduzir silhuetas (OR 0,54; 95IC% 0,35-0,82), comparados aos não praticantes. Não houve interação entre os EFRF e o estado nutricional na associação com IIC. Conclusões: Os adolescentes que praticam EFRF >300 minutos/semana estão mais propensos a apresentar algum nível de IIC e têm menores chances de reportar o desejo de aumentar silhuetas, independentemente do estado nutricional.

Association between bullying victimization and health risk behavior in adolescents / Associação entre vitimização de bullying e comportamentos de risco à saúde em adolescentes

ABSTRACT Objective: The aim of this study was to examine the association between bullying victimization and health risk behaviors in adolescents. Methods: A representative sample of 1020 adolescents participated in the study. The variables such as bullying, health risk behaviors (tobacco, drugs, alcohol, sedentary behavior, smartphone use, level of physical activity, and sleep), and economic status were assessed using self-reported questionnaires. Odds ratios with 95% confidence intervals (95%CI) were obtained using binary logistic regression and ordinal, gross, and adjusted logistic regression (p<0.05). Results: Victims of bullying were more likely to smoke (OR 1.75; 95%CI 1.28-2.40), consume alcohol (OR1.43; 95%CI 1.05-1.94), have worse sleep quality (OR 1.94; 95%CI 1.28-2.91), and more sedentary behavior (OR 1.43; 95%CI 1.08-1.89) than those who were not bullied. However, victims were more likely to have high levels of physical activity than their non-bullied peers (OR 1.66; 95%CI 1.22-2.27). Conclusions: Bullying victimization was associated with an increased predisposition for the adoption of health risk behaviors. Interestingly, victims were also more prone to participate in physical activity.

RESUMO Objetivo: Examinar a associação entre vitimização por bullying e comportamentos de risco à saúde em adolescentes. Métodos: Uma amostra representativa de 1.020 adolescentes participou do estudo. As variáveis bullying, comportamentos de risco à saúde (tabaco, drogas, álcool, comportamento sedentário, uso de smartphone, nível de atividade física, sono) e situação econômica foram avaliadas por meio de questionários autorreportados. Razões de chance com intervalos de confiança de 95% (IC95%) foram obtidas por meio de regressão logística binária e regressão logística ordinal, bruta e ajustada (p<0,05). Resultados: As vítimas de bullying apresentaram maior probabilidade de fumar (OR 1,75; IC95% 1,28-2,40), consumir álcool (OR 1,43; IC95% 1,05-1,94), ter pior qualidade de sono (OR 1,94; IC95% 1,28-2,91) e apresentar mais comportamento sedentário (OR 1,43; IC95% 1,08-1,89) do que aqueles que não sofreram bullying. No entanto, as vítimas eram mais propensas a ter níveis elevados de atividade física do que os seus pares não vítimas de bullying (OR 1,66; IC95% 1,22-2,27). Conclusões: A vitimização por bullying esteve associada ao aumento da predisposição para a adoção de comportamentos de risco à saúde. Curiosamente, as vítimas também eram mais propensas a participar de atividades físicas.

Acute and chronic response of supervised band-elastic resistance exercise in systemic cytokines levels of bipolar disorders and schizophrenia individuals: A pilot study.

Despite earlier research demonstrating the immunomodulatory effects of acute and chronic exercise in many medical illnesses, there is a lack of literature evaluating the acute and chronic effects of exercise on the cytokine levels in individuals with bipolar disorder (BD) or schizophrenia (SCH). This study aims to examine the acute effects of resistance exercise on cytokines and the chronic effects of resistance exercise by 10 weeks on cytokine levels, symptoms of disease, and muscular strength in individuals with BD and SCH. The included individuals (N=10) performed a single session of band-elastic resistance exercises (six exercises, 3 sets of 12-15 repetitions, 60 seconds of interval between sets). A sub-sample (N=6) of individuals performed a supervised band-elastic resistance exercise program (2 times a week, for 10 weeks, 6 exercises, 3 sets of 12-15 repetitions, 60 seconds of interval). We verified for acute effects: IL-2 (P=0.0085) and IL-4 (P=0.0253) levels increased, while IL-6 decreased (P=0.0435), and for chronic effects: increased IL-2 and IL-4 levels (significant effect size - Pre vs Post), a decrease in disease symptoms, and an increase in muscular strength. This study adds to what is already known about how resistance exercises affect people with BD and SCH in both short-term (systemic cytokines levels) and long-term (symptoms of disease, muscular strength, and systemic cytokines levels).

Physical Activity, Sedentary Behaviour, Sleep and Mental Wellbeing in Family Caregivers of Adults With Intellectual and/or Developmental Disabilities.

BACKGROUND: Canadian 24-h movement guidelines recommend that adults achieve 150 min per week of moderate-to-vigorous physical activity (MVPA), 7-9 h of sleep per night and spend no more than 8-h per day sedentary to optimise health and wellbeing. METHOD: Using a cross-sectional survey of 131 family caregivers of adults with intellectual and developmental disabilities, we aimed to (a) determine whether adherence to these guidelines predicts mental wellbeing in family caregivers and (b) explore the relationship between movement behaviours of family caregivers and their loved ones. RESULTS: While MVPA was found to weakly predict wellbeing, sleep and sedentary behaviour did not. The movement behaviours of the family caregivers were not closely related to that of their loved ones. CONCLUSIONS: Fostering physical activity is important to promote the wellbeing of adults with intellectual and developmental disabilities, as well as their family caregivers. Opportunities to be active together may be even more beneficial.

Nanoscale octopus guiding telomere entanglement: An innovative strategy for inducing apoptosis in cancer cells.

Telomere length plays a crucial role in cellular aging and the risk of diseases. Unlike normal cells, cancer cells can extend their own survival by maintaining telomere stability through telomere maintenance mechanism. Therefore, regulating the lengths of telomeres have emerged as a promising approach for anti-cancer treatment. In this study, we introduce a nanoscale octopus-like structure designed to induce physical entangling of telomere, thereby efficiently triggering telomere dysfunction. The nanoscale octopus, composed of eight-armed PEG (8-arm-PEG), are functionalized with cell penetrating peptide (TAT) to facilitate nuclear entry and are covalently bound to N-Methyl Mesoporphyrin IX (NMM) to target G-quadruplexes (G4s) present in telomeres. The multi-armed configuration of the nanoscale octopus enables targeted binding to multiple G4s, physically disrupting and entangling numerous telomeres, thereby triggering telomere dysfunction. Both in vitro and in vivo experiments indicate that the nanoscale octopus significantly inhibits cancer cell proliferation, induces apoptosis through telomere entanglement, and ultimately suppresses tumor growth. This research offers a novel perspective for the development of innovative anti-cancer interventions and provides potential therapeutic options for targeting telomeres.

Physical stimuli-responsive polymeric patches for healthcare.

Many chronic diseases have become severe public health problems with the development of society. A safe and efficient healthcare method is to utilize physical stimulus-responsive polymer patches, which may respond to physical stimuli, including light, electric current, temperature, magnetic field, mechanical force, and ultrasound. Under certain physical stimuli, these patches have been widely used in therapy for diabetes, cancer, wounds, hair loss, obesity, and heart diseases since they could realize controllable treatment and reduce the risks of side effects. This review sketches the design principles of polymer patches, including composition, properties, and performances. Besides, control methods of using different kinds of physical stimuli were introduced. Then, the fabrication methods and characterization of patches were explored. Furthermore, recent applications of these patches in the biomedical field were demonstrated. Finally, we discussed the challenges and prospects for its clinical translation. We anticipate that physical stimulus-responsive polymer patches will open up new avenues for healthcare by acting as a platform with multiple functions.

Replacement of backfat with vegetable oils or their oleogels in emulsion-type sausage significantly change the digestibility of meat protein.

Replacing animal fat with vegetable oil occurred extensively in the meat products, but whether these replacements will affect the nutrition of meat protein was seldom revealed. Effect of substitution of back fat (BF) by vegetable oils or their oleogels in emulsion-type sausage on the digestion process of meat protein was investigated. Replacement of BF with vegetable oils and their oleogels decreased the G'/G" values of meat paste, and oleogels largely weakened the structure of sausages. The substitution significantly reduced the liberation of -NH2 during the initial gastric and intestinal digestion, and resulted in bigger digests in CLSM images. The reduced gastric digestibility induced by substitution was shown to be related to the reduced stability of gastric digests, which can be attributed to the larger particle size and reduced viscosity of digests. These results highlighted stability of digests as a key point changing the digestion process of meat protein.

Protonated carbon nitride for rapid photocatalytic sterilization via synergistic oxidative damage and physical destruction.

Photocatalytic disinfection is an eco-friendly strategy for countering bacterial pollution in aquatic environments. Numerous strategies have been devised to facilitate the generation of reactive oxygen species (ROS) within photocatalysts, ultimately leading to the eradication of bacteria. However, the significance of the physical morphology of photocatalysts in the context of sterilization is frequently obscured, and the progress in the development of physical-chemical synergistic sterilization photocatalysts has been relatively limited. Herein, graphitic carbon nitride (g-C3N4) is chemically protonated to expose more sharp edges. PL fluorescence and EIS results indicate that the protonation can accelerate photogenerated carrier separation and enhance ROS production. Meanwhile, the sharp edges on the protonated g-C3N4 facilitate the physical disruption of cell walls for further promoting oxidative damage. Protonated C3N4 demonstrated superior bactericidal performance than that of pristine g-C3N4, effectively eliminating Escherichia coli within 40 minutes under irradiation. This work highlights the significance of incorporating physical and chemical synergies in photocatalyst design to enhance the disinfection efficiency of photocatalysis.

Characterization and function of particulate organic matter: Evidence from lakes undergoing ecological restoration.

Particulate organic matter (POM) plays a crucial role in the organic composition of lakes; however, its characteristics remain poorly understood. This study aimed to characterize the structure and composition of POM in Lake Baiyangdian using many kinds of techniques and investigate the effects of different extracted forms of POM on water quality. The suspended particulate matter in the lake had complex compositions, with its components primarily derived from aquatic plants and their detritus. The organic matter content of the suspended particulate matter was relatively high (organic carbon content 27.29-145.94 g/kg) for the sum of three extractable states (water-extracted organic matter [WEOM], humic acid, and fulvic acid) and one stable bound state (humin). Spatial distribution analysis revealed that the POM content in the water increased from west to east, which was consistent with the water flow pattern influenced by the Baiyangdian water diversion project. Fluorescence spectroscopy analysis of the WEOM showed three prominent peaks with excitation/emission wavelengths similar to those of dissolved organic matter peaks. These peaks were potentially initial products of POM conversion into dissolved organic matter. Furthermore, the intensity of the WEOM fluorescence peak (total fluorescence peak intensity) was negatively correlated with the inorganic nitrogen concentration in water (p < 0.01), while the intensity of the HA fluorescence peak showed a positive correlation with the inorganic nitrogen concentration (p < 0.01). This suggested that exogenous organic matter inputs led to the diffusion of alkaline dissolved nitrogen from sediment into water, while degradation processes of aquatic plant debris contributed to the decrease in inorganic nitrogen concentrations in the water column. These findings enhance our understanding of POM characteristics in shallow lakes and the role of POM in shallow lake ecosystems.

Psychometric Properties of the Aggression Questionnaire (AQ) in a sample of Colombian children and adolescents / Propiedades psicométricas del Cuestionario de Agresión (AQ) en una muestra de niños y adolescentes colombianos

Abstract Objective: To establish the psychometric properties of the aggression questionnaire (AQ) in a sample of Colombian children and adolescents. Method: The AQ was submitted to the judgment of seven experts in order to verify and adjust the clarity of the items taking into account the characteristics of the Colombian population. Following this analysis and adjustment of items, the instrument was applied to a sample of 892 participants between 10 and 23 years of age. For validity, evidence of internal structure was taken into account through confirmatory factor analysis and evidence based on the relationship with other variables. Results: Confirmatory factor analysis showed two models, one of factorial correlation and the other of second order indicating a model fit. Likewise, internal consistency was calculated by means of the Omega index, which showed precision in the measures for each factor in each of the models. The analysis suggested the elimination of four items. Conclusions: The first-order model was chosen because the empirical evidence shows that it satisfactorily operationalises the theoretical model of aggressive behaviour with which the instrument was constructed, assuming that the four subscales are necessary as a whole, but by themselves are not sufficient to assess aggressive behaviour by means of its items.

Resumen Objetivo: Establecer las propiedades psicométricas del cuestionario de agresión (CA) en una muestra de niños y adolescentes colombianos. Método: El AQ fue sometido al juicio de siete expertos con el fin de verificar y ajustar la claridad de los ítems teniendo en cuenta las características de la población colombiana. Luego de este análisis y ajuste de ítems, se aplicó el instrumento a una muestra de 892 participantes entre 10 y 23 años de edad. Para la validez se tuvo en cuenta la evidencia de la estructura interna a través del análisis factorial confirmatorio y la evidencia basada en la relación con otras variables. Resultados: El análisis factorial confirmatorio mostró dos modelos, uno de correlación factorial y otro de segundo orden indicando un ajuste del modelo. Asimismo, se calculó la consistencia interna mediante el índice Omega, que mostró precisión en las medidas para cada factor en cada uno de los modelos. El análisis sugirió la eliminación de cuatro ítems. Conclusiones: Se eligió el modelo de primer orden porque la evidencia empírica muestra que operacionaliza satisfactoriamente el modelo teórico de conducta agresiva con el que se construyó el instrumento, asumiendo que las cuatro subescalas son necesarias en su conjunto, pero por sí solas no son suficientes para evaluar la conducta agresiva por medio de sus ítems.

Mid-Childhood Plasma Concentrations of Per- and Polyfluoroalkyl Substances, Modifiable Lifestyle Factors, and Bone Mineral Density Through Late Adolescence.

There is limited research on associations of per- and polyfluoroalkyl substances (PFAS) with areal bone mineral density (aBMD) through adolescence and whether bone-strengthening factors ameliorate effects. In the Project Viva cohort (N = 484; 50% female), we used sex-stratified linear regression and quantile g-computation mixture models to examine associations of mid-childhood (median: 7.8 years; 2007-2010) plasma PFAS concentrations with a dual-energy X-ray absorptiometry total-body aBMD Z-score in early and late adolescence (median: 12.9 and 17.6 years, respectively). We explored stratum-specific estimates by parent/self-reported physical activity and dairy intake. Using linear mixed models, we evaluated associations with aBMD accrual from mid-childhood through late adolescence. Females with higher perfluorooctanoate (PFOA) and perfluorodecanoate (PFDA) had lower early adolescent aBMD Z-score [e.g., ß(95%CI)] per doubling PFOA: -0.19(-0.41, 0.03)]. Youth with higher PFOA and PFDA had lower late adolescent aBMD Z-score, but CIs were wide [e.g., PFOA: females, -0.12(-0.40, 0.16); males, -0.10(-0.42, 0.21)]. Mixture models generally corroborated single PFAS results, and in linear mixed models, females with higher PFAS concentrations, and males with higher PFOA, had slower aBMD accrual. Less active males with higher PFOA, PFDA, and the PFAS mixture had lower late adolescent aBMD Z-score. Some PFAS appeared more negatively associated with the aBMD Z-score among those who consumed less dairy, but there was not consistent evidence of effect modification. Exposure to select PFAS may affect bone accrual through adolescence, with possible resilience conferred by greater physical activity and dairy intake.

Quantifying the use of natural history collections.

Measuring the use of natural history collections is essential to understand their past and present impact on science, to underpin decisions about their management and to assist with deploying them optimally to address societal challenges. Using the vast natural history collections of Naturalis Biodiversity Center as an example, this paper assesses the significance and relevance of quantifying collection use. Four aspects are discussed: 1. standardisation, 2. relevance of having standardised metrics on collection use, 3. the level of detail and completeness of the information and 4. the interactions between digitisation of collections and physical collection use. Based on a set of transparent and objective parameters to describe collection use, it is proposed to further develop these into international standards.

Developing and Evaluating a Program to Support Preparation for Aging: A Case Study from Phuket Province, Thailand.

Introduction: Thailand's aging population is increasing. While the societal impact of aging is recognized, formal programs to support pre-retirement planning are currently lacking. This study aimed to develop and evaluate a program specifically designed to address this gap and support individuals to prepare for a healthy and fulfilling later life. Methods: We employed a quasi-experimental, one-group pre-test/post-test design to evaluate a newly developed program focused on pre-retirement preparation. The program consisted of four, 3-hr modules delivered weekly. Voluntary participants (N = 25) were aged 50 to 59 years, physically active, and committed to attending all modules. Participants' knowledge and self-reported preparedness for aging were assessed before and after program completion. Results: The program led to a statistically significant increase in participants' overall knowledge of aging (z = -2.010, p < .05). While specific areas of preparation did not show statistically significant individual differences, mean scores improved across all aspects of preparation. This may reflect the existing health knowledge of some participants and their proactive approach to aging preparation (80% reported some prior preparation). Conclusion: This study demonstrates the effectiveness of a pre-retirement preparation program in enhancing knowledge and self-reported preparedness for aging. Findings suggest that such programs can stimulate middle-aged adults to plan for their future well-being. This study underscores the need for a more holistic approach to pre-retirement preparation. Future programs should consider incorporating content beyond health and finances, potentially including social life planning as identified in this research. Future research could explore program modifications, such as extended formats and content tailored to specific needs.

Impact of physical exercise (strength and stretching) on repairing craniovertebral and reducing neck pain: A systematic review and meta-analysis.

Background: The craniovertebral (CV) junction is crucial for head support, mobility, and protecting the upper spinal cord and vital nerve structures. Disorders in this area can cause severe symptoms such as neck pain, restricted movement, and neurological issues such as headaches and balance problems. Exercise and physical activity improves muscle strength, flexibility, joint stability, reducing pain, and enhancing joint function, while specifically for the CV junction, exercise can relieve muscle tension, boost blood flow, and improve posture, although the specific impact on CV junction health remains underexplored. Methods: A comprehensive literature search was conducted using databases MEDLINE, Cochrane, Lilacs, and ScienceDirect, alongside manual searches through reference lists. The review focuses on exercise and CV junction issues and includes randomized controlled trials, cohort or case-control studies, and systematic reviews. Primary outcomes include pain levels, joint mobility, function, and quality of life. Results: Results yield four meta-analyses with corrective exercise and conventional exercise in improving forward head posture risk difference 0.00 (-0.09, 0.09) 95% confidence interval (CI), between cervical and thoracic exercises odds ratio 1.04 (0.59, 1.84) 95% CI. Comparing exercise treatment and physiotherapy showed risk difference 0.11 (-0.10, 0.32) 95% CI and the comparative analysis between training and no treatment showed risk difference 0.09 (-0.01, 0.20) 95% CI. Conclusion: Exercise-based rehabilitation programs tailored to patients with CV junction problems offer robust evidence, benefiting clinical management, and prevention efforts.

Stakeholder perceptions of physical literacy: results from a national consultation in England.

Background: There is a lack of evidence of stakeholder perspective and understanding of physical literacy among relevant stakeholders from England. As part of research commissioned by Sport England to develop a physical literacy consensus statement for England, this study presents findings from the first national consultation with stakeholders in England. Methods: One hundred and ninety-three individual stakeholders (50.3%) from education, community sport, national governing bodies of sport, physical activity and sport coaching sectors completed an online survey consisting of fixed item and open ended questions designed to examine their knowledge, understanding, perceptions and practices relating to physical literacy. Results: Responses from stakeholders suggested there was confusion in use of the term physical literacy in practice and confusion regarding the definition of physical literacy. Most respondents suggested they were involved in physical literacy related activity and understood the term. However, when probed the physical literacy related activity they referred to was likely not actually physical literacy related. Understanding of the term physical literacy was inconsistent in general. Stakeholders considered the affective, social, physical and cognitive areas (domains) of learning to be most important for developing a positive relationship with movement, sport and physical activity for life. Conclusions: While stakeholders are aware of the term "physical literacy" and hold value of it within their practice, there remain key misconceptions relating to what physical literacy is, and debate as to whether any existing definitions truly capture the construct of physical literacy.

Exploring the use of wearable sensors for assessing risk factors during orthopedic surgeries: A protocol for data collection.

During orthopedic surgeries, surgeons are generally exposed to prolonged periods of standing, awkward and sustained body postures, and forceful movements, which can increase the likelihood of developing work-related musculoskeletal disorders (WRMSD). Therefore, this study proposes a protocol to measure parameters related to physical risk factors contributing to lower limb WRMSD, during orthopedic surgery procedures. The protocol development was preceded by an initial phase of understanding and specifying the context of use, followed by pre-tests in laboratory environment. It integrates a motion capture system, using inertial measurement units (IMU) to collect posture data from hip, knee, and ankle, and electromyography system (EMG) to measure and record data from muscle activity of biceps femoris, rectus femoris, and gastrocnemius lateralis. Pre-tests provided insights for protocol optimization, estimating a 3-hour data collection session per surgery due to sensor battery limitations, streamlining the process by placing EMG sensors before IMU and refining thigh sensor placement strategies. The protocol presents an opportunity for a real-time and quantitative approach to monitor surgeon's exposure to risk factors contributing to lower limb WRMSD while performing surgical procedures. Two months after pre-tests, the protocol implementation began in a real work context. The study's final outcomes fall outside the paper's scope.
