Lung and blood perioperative metalloproteinases in patients undergoing oncologic lung surgery: Prognostic implications.

BACKGROUND: Metalloproteinases (MMPs) have been reported to be related to oncologic outcomes. The main goal of the study was to study the relationship between these proteins and the long-term prognosis of patients undergoing oncologic lung resection surgery. METHODS: This was a substudy of the phase IV randomized control trial (NCT02168751). We analyzed MMP-2, -3, -7, and -9 in blood samples and bronchoalveolar lavage (LBA) and the relationship between MMPs and long postoperative outcomes (survival and disease-free time of oncologic recurrence). RESULTS: Survival was longer in patients who had lower MMP-2 levels than those with higher MMP-2 in blood samples taken 6 h after surgery (6.8 vs. 5.22 years; p = 0.012) and MMP-3 (6.82 vs. 5.35 years; p = 0.03). In contrast, survival was longer when MMP-3 levels were higher in LBA from oncologic lung patients than those with lower MMP-3 (7.96 vs. 6.02 years; p = 0.005). Recurrence-free time was longer in patients who had lower MMP-3 levels in blood samples versus higher (5.97 vs. 4.23 years; p = 0.034) as well as lower MMP-7 (5.96 vs. 4.5 years; p = 0.041) or lower MMP-9 in LBA samples (6.21 vs. 4.18 years; p = 0.012). CONCLUSION: MMPs were monitored during the perioperative period of oncologic lung resection surgery. These biomarkers were associated with mortality and recurrence-free time. The role of the different MMPs analyzed during the study do not have the same prognostic implications after this kind of surgery.

Intersecting risk factors for physical inactivity among Canadian adults.

Background: On average, 45% of Canadian adults meet the recommended 150 minutes per week of moderate-to-vigorous physical activity. This singular statistic masks a wide range of adherence levels among different groups within the population. The purpose of this paper is to determine how sex, age, and family arrangement intersect with known risk factors for physical inactivity to identify groups within the Canadian population most at risk of not meeting the physical activity recommendation. Methods: Using six combined cycles of the Canadian Health Measures Survey (from 2007 to 2019), this study examines how the percentage of Canadian males and females aged 18 to 79 years meeting the physical activity recommendation differs across sociodemographic, family arrangement, and health factors. Logistic regression was used to examine whether the association between specific factors and adherence to the physical activity recommendation differed by sex. Latent class analysis was used to identify sex-specific combinations of sociodemographic, family arrangement and health-related factors within the Canadian population that are associated with varying levels of adherence to the physical activity recommendation. Results: More males met the physical activity recommendation compared with females (49% versus 38%). Latent classes with the lowest adherence to the physical activity recommendation (19% among females and 29% among males) primarily included those who were single or married with no children and who had a high probability of having many risk factors for physical inactivity, including being older, having a lower education, having lower income, smoking, having central adiposity, and having poor or fair self-rated general health. Latent classes with the highest adherence to the physical activity recommendation (61% among females and 67% among males) primarily included individuals with no spouse and no children and who had a low probability of having any risk factors for physical inactivity. For females, an additional class (32% of which met the physical activity recommendation) comprised young single mothers who had several risk factors for physical inactivity, including having low income, smoking and having central adiposity. Interpretation: Understanding how risk factors for physical inactivity intersect with sex, age, and family arrangement may inform strategies aimed at increasing physical activity among those who are most vulnerable.

Delayed onset facilitates subsequent retrieval of words during language comprehension.

Prior research has shown that during language comprehension, memory representations associated with premodified words (e.g., the injured and dangerous bear) are retrieved faster from memory than those associated with unmodified words (e.g., the bear). Current explanations attribute this effect to the semantic richness of modified words. However, it is not clear whether the presence of modifying words are in fact necessary for a retrieval benefit. Premodifiers necessarily delay the onset of the target word (i.e., bear), and temporal delays may heighten attention to upcoming stimuli, and/or strengthen encoding by producing free time during encoding, facilitating subsequent retrieval. We therefore examined whether a simple delay in the onset of the target can produce a retrieval benefit. Our results show that delayed onset facilitates the subsequent retrieval of target words in the absence of any modifying information. These results lend support to models of language comprehension according to which delays may enhance attention to upcoming words, and also to models of working memory based on which free time replenishes encoding resources, strengthening the memory trace of encoded information and facilitating its retrieval at a subsequent point. Our results also contribute to current memory-based theories of sentence comprehension by showing that retrieval from memory may be affected by nonlinguistic factors such as delay-induced attention enhancement, or free time during encoding.

Evaluation of Exacerbation and Symptom-Free Time in Patients with COPD.

In clinical practice, clinicians mainly focus on Chronic Obstructive Pulmonary Disease (COPD) exacerbations and symptoms, while patients may prefer to evaluate periods free of COPD exacerbations and deteriorated symptoms. The latter would suit the positive health approach that centralizes people and their beliefs. We aimed to identify patient characteristics and health outcomes relating to: 1) COPD exacerbation-free days; 2) days with no more symptoms than usual; and 3) combined COPD exacerbation and comorbid flare-up-free days (i.e. chronic heart failure, anxiety, depression flare-ups) using negative binomial regression analyzes. Data were obtained from two self-management intervention trials including COPD patients with and without comorbidities. 313 patients (mean age 66.0 years, 63.6% male, 68.7% comorbidity) were included. Better baseline chronic respiratory questionnaire (CRQ) fatigue (incidence rate ratio (IRR) = 1.03 (95% CI 1.01-1.05), p = 0.02) and mastery scores (IRR = 1.03 (95% CI 1.00-1.06), p = 0.04) and fewer courses of antibiotics (IRR = 0.95 (95% CI 0.94-0.96), p < 0.01) were related to more COPD exacerbation-free days. Additionally, better baseline CRQ fatigue (IRR = 1.05 (95% CI 1.00-1.10), p = 0.04) and mastery scores (IRR = 1.06 (95% CI 1.00-1.12), p = 0.04), fewer courses of antibiotics (IRR = 0.94 (95% CI 0.91-0.96), p < 0.01), and improved CRQ dyspnea scores over 12 months of follow-up (IRR = 1.07 (95% CI 1.01-1.12), p < 0.01) were correlated to more days free of deteriorated symptoms. Less baseline dyspnea (modified Medical Research Council score) (IRR = 0.95 (95% CI 0.92-0.98), p < 0.01) and fewer courses of antibiotics (IRR = 0.94 (95% CI 0.93-0.95), p < 0.01) were associated with more combined COPD exacerbation and comorbid flare-up-free days. Healthcare professionals should be aware that less fatigue and better mastering of COPD relate to more exacerbation and symptom-free time in COPD patients.

Tempo livre: agonia conceitual e impossibilidade epistêmica / Free time: conceptual agony and epistemic impossibility

Neste ensaio revisitamos uma problemática básica presente na confluência entre as sociologias do lazer e do trabalho, isto é, de que o tempo livre estaria acorrentado ao tempo de trabalho. Lembramos que são conhecidas as distinções conceituais sobre as atividades liberadas dos tempos do trabalho e as atividades exercidas por prazer no tempo livre. Assim, neste escrito partirmos da premissa crítica de que no atual capitalismo global não podemos isolar as esferas do tempo social cotidiano do tempo social do trabalho. Destacamos a transição do tempo livre de caráter fordista para o tempo livre de caráter toyotista, cuja face neoliberal assumiu uma forma extremamente perversa, conjugando uma agenda sistemática de privatização das instâncias de socialização das tensões e contingências da vida coletiva, de flexibilização dos constrangimentos, de exploração do Trabalho pelo Capital e de desregulação generalizada do Mercado. Direitos Trabalhistas perdidos, desemprego estrutural, instabilidade biográfica e consumismo narcísico parelham a trajetória das massas atomizadas de trabalhadores multi-tarefeiros e proativos, eternamente ocupados e envolvidos em modo full-time. Concluímos, pois, que o tempo livre, sempre inscrito em coerção ideológica, agora é destroçado perante uma sociedade da performance e do cansaço, que não dorme e que está eternamente ocupada.

In this essay we revisit and discuss a basic problem at the confluence between the sociologies of leisure and the sociologies of work, that is, that the free time would be chained to the work time. We recall that are known the conceptual distinctions about the activities released from the time of work and the activities exercised for pleasure in the free time. Thus, in this writing we start from the critical premise that in the current global capitalism we cannot isolate the spheres of everyday social time from the social time of work. We highlight the transition from free time of a Fordist character to free time of a Toyotist character, whose neoliberal face has assumed an extremely perverse form, combining a systematic agenda of privatization of the instances of socialization of the tensions and contingencies of collective life, of flexibilization of the constraints to the exploitation of Labor by Capital and of generalized deregulation of the Market. Lost labor rights, structural unemployment, biographical instability, and narcissistic consumerism pair the trajectory of the atomized masses of multi-tasking, proactive workers, eternally occupied and engaged in full-time mode. We conclude, therefore, that free time, always inscribed in ideological coercion, is now shattered before a society of performance and fatigue, which does not sleep and is eternally occupied.

On the Different Abilities of Cross-Sample Entropy and K-Nearest-Neighbor Cross-Unpredictability in Assessing Dynamic Cardiorespiratory and Cerebrovascular Interactions.

Nonlinear markers of coupling strength are often utilized to typify cardiorespiratory and cerebrovascular regulations. The computation of these indices requires techniques describing nonlinear interactions between respiration (R) and heart period (HP) and between mean arterial pressure (MAP) and mean cerebral blood velocity (MCBv). We compared two model-free methods for the assessment of dynamic HP-R and MCBv-MAP interactions, namely the cross-sample entropy (CSampEn) and k-nearest-neighbor cross-unpredictability (KNNCUP). Comparison was carried out first over simulations generated by linear and nonlinear unidirectional causal, bidirectional linear causal, and lag-zero linear noncausal models, and then over experimental data acquired from 19 subjects at supine rest during spontaneous breathing and controlled respiration at 10, 15, and 20 breaths·minute-1 as well as from 13 subjects at supine rest and during 60° head-up tilt. Linear markers were computed for comparison. We found that: (i) over simulations, CSampEn and KNNCUP exhibit different abilities in evaluating coupling strength; (ii) KNNCUP is more reliable than CSampEn when interactions occur according to a causal structure, while performances are similar in noncausal models; (iii) in healthy subjects, KNNCUP is more powerful in characterizing cardiorespiratory and cerebrovascular variability interactions than CSampEn and linear markers. We recommend KNNCUP for quantifying cardiorespiratory and cerebrovascular coupling.

Development of europium(III) complex functionalized silica nanoprobe for luminescence detection of tetracycline.

Increasing awareness of the health and environment impacts of the antibiotics misuse or overuse, such as tetracycline (TC) in treatment or prevention of infections and diseases, has driven the development of robust methods for their detection in biological, environmental and food systems. In this work, we report the development of a new europium(III) complex functionalized silica nanoprobe (SiNPs-Eu3+) for highly sensitive and selective detection of TC residue in aqueous solution and food samples (milk and meat). The nanoprobe is developed by immobilization of Eu3+ ion onto the surface of silica nanoparticles (SiNPs) as the emitter and TC recognition unit. The ß-diketone configuration of TC can further coordinate with Eu3+ steadily on the surface of nanoprobe, facilitating the absorption of light excitation for Eu3+ emitter activation and luminescence "off-on" response. The dose-dependent luminescence enhancement of SiNPs-Eu3+ nanoprobe exhibits good linearities, allowing the quantitative detection of TC. The SiNPs-Eu3+ nanoprobe shows high sensitivity and selectivity for TC detection in buffer solution. Time resolved luminescence analysis enables the elimination of autofluorescence and light scattering for highly sensitive detection of TC in milk and pork mince with high accuracy and precision. The successful development of SiNPs-Eu3+ nanoprobe is anticipated to provide a rapid, economic, and robust approach for TC detection in real world samples.

[Necessity of Pressure-free Time at Work-Historical Consideration].

Many developed countries, including Japan, have capitalist economies based on market principles. In capitalism, businesses try to develop new products and increase their added value, and expand the market in order to generate new profits. Owing to the universalization of capitalist efficiency, our daily lives are becoming condensed to only the necessary things in life. In addition, the advancement of science and technology, which is the driving force behind the expansion of profits, has forced people to become obsessed with new technology and information, and as a result, we have also lost our mental comfort. In this paper, first, we explain the time required to secure the energy necessary for human survival throughout human history. Second, we describe labor productivity with the emergence and development of capitalism. Third, we explain the difference between essential time and pressure-free time, and consider the necessity of pressure-free time during working hours. Finally, we discuss the relationships among pressure-free time, presenteeism, and work engagement.

The Association Between Screen Time and Outdoor Time on Adolescent Mental Health and Academic Performance: Evidence from Rural China.

Purpose: We examine how adolescent free time allocation-namely, screen time and outdoor time-is associated with mental health and academic performance in rural China. Methods: This paper used a large random sample of rural junior high school students in Ningxia (n = 20,375; age=13.22), with data collected from self-reported demographic questionnaires (to assess free time allocation), the Strengths and Difficulties Questionnaire (to assess mental health), and a standardized math test (to measure academic performance). We utilized a multivariate OLS regression model to examine associations between free time allocation and adolescent outcomes, controlling for individual and family characteristics. Results: Our sample's screen time and outdoor time both averaged around 1 hour. About 10% of the sample adolescents reported behavioral difficulties, while a similar percentage (11%) reported abnormal prosocial behaviors. Adolescents with higher levels of screen time (>2 hours) were 3 percentage points more likely to have higher levels of behavioral difficulties (p<0.001), indicating that excessive screen time was associated with worse mental health. Meanwhile, outdoor time was associated with better mental health, and positive correlations were observed at all levels of outdoor time (compared to no outdoor time, decreasing the likelihood of higher levels of behavioral difficulties by between 3 and 4 percentage points and of lower prosocial scores by between 6 and 8 percentage points; all p's<0.001). For academic performance, average daily screen times of up to 1 hour and 1-2 hours were both positively associated with standardized math scores (0.08 SD, p<0.001; 0.07 SD, p<0.01, respectively), whereas there were no significant associations between outdoor time and academic performance. Conclusion: Using a large sample size, this study was the first to examine the association between adolescent free time allocation with mental health and academic performance, providing initial insights into how rural Chinese adolescents can optimize their free time.

Lab cognition going wild: Implementing a new portable touchscreen system in vervet monkeys.

Touchscreen technology has provided researchers with opportunities to conduct well-controlled cognitive tests with captive animals, allowing researchers to isolate individuals, select participants based on specific traits, and control aspects of the environment. In this study, we aimed to investigate the potential utility of touchscreen technology for the study of cognition in wild vervet monkeys. We assessed the viability of touchscreen testing by comparing rates of participation between wild and sanctuary-housed vervets. Additionally, we compared performance on a simple associative learning task in order to verify that wild participants are able to engage meaningfully with a touchscreen task presented in their natural environment. We presented eight groups of vervet monkeys (four wild and four sanctuary groups, totalling 240 individuals) with a portable touchscreen device. The touchscreen displayed tasks in which food rewards could be gained by touching a stimulus displayed on the screen. We assessed individuals' likelihood of interacting with the touchscreen, their frequency of participation, and their performance on a simple associative learning task. We found that sanctuary-housed monkeys were more likely to interact with the touchscreen. Participation in wild vervet monkeys was influenced by sex and age. However, monkeys in the two contexts (sanctuary vs. wild) did not differ in their performance on a simple associative learning task. This study demonstrates that touchscreen technology can be successfully deployed in a population of wild primates. This gives us a starting point to test animal cognition under natural conditions that include varying group composition, environmental challenges and ongoing activities such as foraging, which are challenging to recreate in captivity. While rates of participation were lower than those found in captivity, reasonable sample sizes can be achieved, and wild primates can successfully learn touchscreen tasks in a manner comparable to their captive counterparts.

A Novel Approach to Determining the Alactic Time Span in Connection with Assessment of the Maximal Rate of Lactate Accumulation in Elite Track Cyclists.

PURPOSE: Following short-term all-out exercise, the maximal rate of glycolysis is frequently assessed on the basis of the maximal rate of lactate accumulation in the blood. Since the end of the interval without significant accumulation (talac) is 1 of 2 denominators in the calculation employed, accurate determination of this parameter is crucial. Although the very existence and definition of talac, as well as the validity of its determination as time-to-peak power (tPpeak), remain controversial, this parameter plays a key role in anaerobic diagnostics. Here, we describe a novel approach to determination of talac and compare it to the current standard. METHODS: Twelve elite track cyclists performed 3 maximal sprints (3, 8, and 12 s) and a high-rate, low-resistance pedaling test on an ergometer with monitoring of crank force and pedaling rate. Before and after each sprint, capillary blood samples were taken for determination of lactate accumulation. Fatigue-free force-velocity and power-velocity profiles were generated. talac was determined as tPpeak and as the time point of the first systematic deviation from the force-velocity profile (tFf). RESULTS: Accumulation of lactate after the 3-second sprint was significant (0.58 [0.19] mmol L-1; P < .001, d = 1.982). tFf was <3 seconds and tPpeak was ≥3 seconds during all sprints (P < .001, d = - 2.111). Peak power output was lower than maximal power output (P < .001, d = -0.937). Blood lactate accumulation increased linearly with increasing duration of exercise (R2 ≥ .99) and intercepted the x-axis at ∼tFf. CONCLUSION: Definition of talac as tPpeak can lead to incorrect conclusions. We propose determination of talac based on tFf, the end of the fatigue-free state that may reflect the beginning of blood lactate accumulation.

Adolescent psychological well-being during the COVID-19 lockdown: the role of leisure activities and online peer communication.

The present study investigated the effects of leisure activities and online peer relationships on the development of psychological difficulties in adolescents during the COVID-19 lockdown in Italy. Data were collected in April and May 2020. The parents of 1,020 Italian adolescents aged 14-18 (51.9% girls) completed questionnaires about the experiences and behaviors of their children before and during the lockdown. A moderation regression analysis was applied to test the research hypotheses. The findings indicated that adolescents who were more active in sports and social activities prior to the COVID-19 pandemic showed greater psychological distress during the lockdown. Moreover, increased reading, game playing, and exercise during the lockdown effectively compensated for the interruption of pre-pandemic sports and social activities, and represented a protective factor for adolescents' mental health. Finally, increased online contact with peers during the lockdown protected against the development of psychological difficulties, regardless of adolescents' engagement in sports and social activities prior to the pandemic. The findings provide new and useful information about the role of leisure activities and online contact with peers in protecting against psychological difficulties in adolescents, especially during situations of isolation and social distancing, as in the COVID-19 national lockdown.

Evaluation of the Influence of Biological Factors during the Course of Treatment in Patients with Ovarian Cancer.

The aim of this study was to evaluate the influence of ß-endorphins and serotonin on the course of treatment, disease-free time, and overall survival of patients with ovarian cancer. This study may contribute to the identification of modifiable factors that may influence the treatment of ovarian cancer. The research was carried out in a group of 162 patients of which 139 respondents were included in the research; ovarian cancer was diagnosed in 78 of these patients. The study consisted of three stages. In the first stage of diagnostics, a survey among the patients was carried out. In the second stage-5 mL of blood was collected from each patient (n = 139) in the preoperative period to determine the concentration of ß-endorphin and serotonin. In the third stage-blood samples were collected from those patients who had completed chemotherapy treatment or had surgery. Concentrations of ß-endorphin and serotonin were measured by the Luminex method, using the commercial Luminex Human Discovery Assay kit. The average age of the patients was 62.99 years. The level of ß-endorphin significantly differs among patients diagnosed with ovarian cancer and among patients in the control group (202.86; SD-15.78 vs. 302.00; SD-24.49). A lower level of ß-endorphins was found in the patients with a recurrence of the neoplastic process compared to those without recurrence (178.84; SD-12.98 vs. 205.66; SD-13.37). On the other hand, the level of serotonin before chemotherapy was higher in the group of people with disease recurrence compared to those without recurrence (141.53; SD-15.33 vs. 134.99; SD-10.08). Statistically significantly positive correlations were found between the level of ß-endorphin and both disease-free time (ß-endorphin levels before chemotherapy: rho Spearman 0.379, p < 0.027; ß-endorphin levels after chemotherapy: rho Spearman 0.734 p < 0.001) and survival time (ß-endorphin levels before chemotherapy: rho Spearman 0.267, p < 0.018; ß-endorphin levels after chemotherapy: rho Spearman 0.654 p < 0.001). 1. The levels of serotonin and ß-endorphin levels are significantly related to ovarian cancer and change during treatment. 2. High mean preoperative concentrations of ß-endorphins were significantly related to overall survival and disease-free time.

The Level and Factors Differentiating the Physical Fitness of Adolescents Passively and Actively Resting in South-Eastern Poland-A Pilot Study.

Physical activity (PA) is defined as any bodily movement produced by skeletal muscles that requires energy expenditure. Due to civilization's development, we can observe a global decline in physical activity which negatively affects the state of physical and mental health. The physical activity of children and adolescents is a counterpart to their physical fitness. There is also more frequent spending of free time in a passive way rather than actively. The aim of the study was to determine whether there are differences in the physical fitness of young people who rest passively in relation to those who rest actively. In addition, it was checked whether factors, such as age, weight, body height and BMI differentiate the level of fitness in adolescents. Study group: 25 boys and 25 girls declaring active leisure activities. Control group: 25 boys and 25 girls declaring passive leisure activities. Age of the respondents ranged from 11 to 15 years (Me = 13; SD = 1.23). The research used: the author's questionnaire and the Index of Physical Fitness of K. Zuchora. The results were statistically developed. The youth who spend their free time actively were characterised by a higher level of physical fitness than their peers who choose passive recreation. The students with a higher BMI obtained worse results than the children with a lower body mass index. In both groups, slightly better results were obtained by girls. A significant relationship between age and results has been observed in the control group-the results increased with increasing age. The level of physical fitness is higher in active forms of recreation than in passive rest. Physical fitness tends to increase with age but decreases with increasing BMI. Girls are characterised by a higher level of physical fitness than boys.

Free time, gender and the pandemic: An exploration of children's daily routines in the times of COVID-19 in Chile.

This article discusses the differentiation by gender displayed by children between 8 and 12 years old on how they used their free time during the COVID-19 pandemic in Chile. This study had a qualitative approach, where 43 in-depth interviews were conducted with children from three different regions of the country, using participatory photo-elicitation as the central tool. The main results of the study show a configuration of free time based on gender stereotypes, showing that boys are the ones who most adhere to such stereotypes, triggering a crisis in the identity construction of masculinities during childhood. The study also suggests that socioeconomic and territorial differences between children configures different experiences of the use of free time.

Stroke Patients' Free-Time Activities and Spatial Preferences During Inpatient Recovery in Rehabilitation Centers.

OBJECTIVES: To investigate which spaces stroke patients visit in their free time while undergoing inpatient recovery in rehabilitation centers, what activities they engage in, and what kind of spaces they want. BACKGROUND: Research studies consistently show that stroke patients are highly inactive during rehabilitation. Much remains unknown about what patients do in their free time and how the built environment might affect their behavior and activities. METHODS: Patients' free-time activities were recorded via patient shadowing (n = 70, 840 hr), and their spatial preferences were collected using a survey (n = 60) in seven rehabilitation centers. Each participant was observed over one typical day (12 consecutive hours). Their activities, durations, and locations were recorded using floor plans and time log sheets. RESULTS: Six main themes emerged from the analysis of shadowing data and patient surveys: (1) spending most free time in their room, (2) corridor as the overlooked activity hub, (3) food and beverage stations as triggers of activity, (4) wanting to socialize, (5) variety of common spaces for different activities is desired, and (6) common room's atmosphere, comfort, style, and view are important. Even though socializing with other patients was mentioned as a primary reason for visiting common spaces in the survey, patients spent most of their free time alone. CONCLUSIONS: Corridor emerged as a space with great potential to motivate and support various activities of patients. Patients' free-time activities could contribute to their recovery, and the built environment may play a role in facilitating and supporting these activities.

Assessment of Physical Well-Being and Leisure Time of Polish Students during the COVID-19 Outbreak.

This project aims to recognize the school experiences of Polish students during the COVID-19 outbreak; we focused on the area of assessment of physical well-being and leisure time. Nearly two thousand primary or secondary school students aged 9 to 20 participated in the survey. Running descriptive statistics, frequency analysis, and significant difference tests, we found that 45% of students thought their physical well-being during the COVID-19 outbreak worsened compared to pre-pandemic times. Boys declared they felt better in their physical well-being than girls (p < 0.001). Most students noticed changes in the quality of their leisure time activities; boys were happier than girls in their free time during the outbreak (p < 0.001). Learners' ages also differentiated the assessment of their physical well-being (p < 0.001) and leisure time (p < 0.001). The youngest students more often assessed their experiences in the researched fields as good or increased, while the older groups more often noticed a decrease. Multinomial logistic regression proved that the differences in the assessments of physical well-being and leisure time could be explained to the greatest extent by age and gender, whereas the place of residence and school location were insignificant. All in all, our study confirms the dominance of the adverse effects of the COVID-19 pandemic on physical well-being and changes in leisure time. As such, it is advisable (during and after outbreaks) to support children and adolescents by targeting individual and institution levels. We recommend developing techniques to reduce stress and information overload, increasing creative ways of spending leisure time, supporting families in navigating children's free time, and expanding social support networks.

Sobre a autonomia na definição da temporalidade livre dos médicos / About the autonomy of the definition of free time of doctors

Objetivou-se compreender a autonomia de médicos recém-especialistas na definição de suas temporalidades livres e as possíveis repercussões nos diferentes âmbitos de suas vidas. Por meio de uma pesquisa exploratória, de cunho qualitativo, sete médicos especialistas responderam a um roteiro de entrevista semiestruturada e um pressuposto de tempos de atividades, compreendidos através da análise de conteúdo de Bardin. Observou-se que os médicos compreendem o tempo livre em oposição ao trabalho e afirmam não o possuir. Destacam ainda que a existência de tempo livre é decorrência da especialidade escolhida, menor carga de trabalho, conclusão da residência e decisão pessoal. Conclui-se que a falta de tempo é uma característica marcante que merece ser melhor refletida no que se refere às consequências dessa realidade sobre o profissional, sua saúde e suas relações sociais.

This study aimed to understand the autonomy of newly doctors experts in defining their free time frames and its possible repercussions in different aspects of your life. From an exploratory research, seven doctors experts answered a semistructured interview guide and an assumption activity times, understood by a qualitative bias by Bardin content analysis. It was observed that doctors understand free time in opposition to the work. They say they don't have free time and want to own it to invest more in them. Also underscore that the existence of free time is due to the type of specialty choice, lower workload, completion of the residence and personal decision. We conclude that lack of time is a remarkable feature that deserves to be better reflected as regards the consequences of this reality on the professional, their health and their social relations.

Leisure Time Use and Adolescent Mental Well-Being: Insights from the COVID-19 Czech Spring Lockdown.

BACKGROUND: As leisure-one of the crucial life domains-was completely disrupted by the COVID-19 pandemic, our study aimed to investigate how adolescents spent their leisure time during the Spring 2020 lockdown. Secondly, we aimed to investigate the associations between the perceived changes in leisure time use, the leisure activities adolescents engaged in, and the associations with well-being during the Spring 2020 lockdown in Czechia. METHODS: Data from 3438 participants were included in this study (54.2% girls; mean age = 13.45, SD = 1.62). First, the initial number of items measuring leisure, electronic media use, and sports was reduced through Principal Component Analysis (PCA). Multivariate linear regression models tested the associations between leisure domains and mental well-being Results: The amount of leisure time, together with socially active leisure and sports and physical activity, formed the strongest positive predictors of mental well-being, whereas idle activities and time spent on electronic media acted as negative predictors. The amount of time spent doing schoolwork was unrelated to mental well-being. CONCLUSIONS: Overall, our results support the idea that leisure as a promoting factor for well-being is not just a matter of its amount but rather of engagement in meaningful and fulfilling activities.
