[Functional recovery in older inpatients with hypertension and ischemic heart disease post-COVID-19.].

Understanding the recovery process of functional abilities post-COVID-19 in older inpatients with arterial hypertension and ischemic heart disease is important for optimising healthcare delivery and resources. Participants in this study were individuals undergoing hospital-based rehabilitation following COVID-19 (average age 66, n=183). They were categorised into groups with arterial hypertension (n=92), ischemic heart disease (n=18), both conditions (n=38), and a control group without these diseases (n=35).

The spectrum of pneumonia among intubated neonates in the neonatal intensive care unit.

We review the pathophysiology, epidemiology, diagnosis, treatment, and prevention of ventilator-associated pneumonia (VAP) in neonates. VAP has been studied primarily in adult ICU patients, although there has been more focus on pediatric and neonatal VAP (neo-VAP) in the last decade. The definition as well as diagnosis of VAP in neonates remains a challenge to date.

Study of absorption and emission spectra of substituted terthiophene compounds by methods of theoretical chemistry.

Terthiophene derivatives attract interest due to their prospective applications in optoelectronic or sensor devices. Due to their nontoxicity they can be considered as suitable candidates in biological applications. Supramolecular organization of the matter is one of the most interesting topics in contemporary materials science.

Young-of-the-year fish as bioindicators of eutrophication and temperature regime of water bodies.

Young-of-the-year fish communities are widely used as bioindicators of various environmental disturbances. This study was conducted from 1997 to 2015 and aims to develop fish trait-based indices of changes in the temperature regime and eutrophication of water bodies in the Dnipro River basin. We identified fish traits that significantly correlate with both temperature and chlorophyll-a concentration optimum: reproduction habitat, oxygen tolerance, and toxicity tolerance.

Context matters: athletes' perception of dopers' values, actions and vulnerabilities.

Background: Although athletes seem to hold uniform views towards non-dopers, their perception of dopers is more nuanced, reflecting positive and negative attributes. Research also indicates that rarely a single factor can explain doping, but a host of reasons that intertwine. A holistic understanding of how values play a role in decisions in anti-doping and the elements that influence athletes' doping vulnerability is timely and warranted.

Body composition in male lifelong trained strength, sprint and endurance athletes and healthy age-matched controls.

Introduction: Aging involves many physiological processes that lead to decreases in muscle mass and increases in fat mass. While regular exercise can counteract such negative body composition outcomes, masters athletes maintain high levels of exercise throughout their lives. This provides a unique model to assess the impact of inherent aging.

Motives for competitive sports participation in masters track and field athletes: Impact of sociodemographic factors and competitive background.

Objectives: Masters athletes due to their lifelong engagement in sport represent a unique group to study motivation for regular physical activity, but there is less scientific data on the sport motives in masters athletes. Therefore, the aim of this study was to evaluate the association of age, sex, education, nationality, competitive background and training amount with sport motives of masters track and field athletes.

Methods: 811 (254 women) athletes aged 35-89 years participated in European Veterans Athletics Championships in the year of 2000.

The evolving value of older biomarkers in the clinical diagnosis of pediatric sepsis.

Sepsis remains the leading cause of childhood mortality worldwide. The evolving definition of pediatric sepsis is extrapolated from adult studies. Although lacking formal validation in the pediatric population, this working definition has historically proven its clinical utility.

Behaviours and Beliefs Related to Whistleblowing Against Doping in Sport: A Cross-National Study.

Background: Whistleblowing has been recognized as an important deterrent of doping in elite competitive sport. The present study examined athletes' knowledge of external whistleblowing channels and on how and where to report doping misconduct, perceived trust in different whistleblowing reporting channels, whistleblowing behaviour and athletes' reasons for reporting (or not) doping misconduct.

Methods: Athletes from Greece ( = 480), the Russian Federation ( = 512) and the United Kingdom ( = 171) completed a structured questionnaire on demographics, knowledge of different whistleblowing channels, perceived trust in internal and external whistleblowing channels, past whistleblowing behaviour and reasons for reporting (or not) doping misconduct.

[Changes in respiratory function and physical performance in middle-aged and old inpatients recovering from COVID-19 after a rehabilitation program.].

Changes in respiratory and physical performance in geriatric inpatients recovering from COVID-19 are of interest for rehabilitation interventions. 56 inpatients (67% women), average age 64±11 years recovering from COVID-19 underwent a comprehensive rehabilitation program (16,9±3,8 days). After the rehabilitation program, the patients showed an improvement in respiratory function: voluntary breath-holding after inhalation - by 19% (p=0,006), breath-holding after exhalation - by 25% (p=0,026), lungs computed tomography (p<0,001); physical performance: handgrip strength - by 14% (p=0,083), preferred walking speed - by 80% (p=0,025); exercise tolerance: distance walked until the first signs of fatigue - by 227% (p<0,001), resting heart rate - by 1% (p=0,011).

Associations of physical performance and physical activity with mental well-being in middle-aged women.

Background: To investigate whether physical performance is independently of physical activity (PA) associated with positive and negative dimensions of mental well-being in middle-aged women.

Methods: Data were drawn from the Estrogenic Regulation of Muscle Apoptosis (ERMA) study in which women 47 to 55 years were randomly selected from the Finnish National Registry. They (n = 909) participated in measurements of physical performance (handgrip force, knee extension force, vertical jumping height, maximal walking speed, and six-minute walking distance).

One Does Not Fit All: European Study Shows Significant Differences in Value-Priorities in Clean Sport.

Doping violates the Spirit of Sport and is thought to contradict the values which underpin this spirit. Values-based education (VBE) has been cited as a key element for creating a clean sport culture across age groups. Culturally relevant VBE requires understanding of the values that motivate athletes from different countries to practice their sport and uphold clean sport values.

Whistleblowing Against Doping Misconduct in Sport: A Reasoned Action Perspective With a Focus on Affective and Normative Processes.

Whistleblowing against doping misconduct represents an effective deterrent of doping use in elite competitive sport. The present study assessed the effects of social cognitive variables on competitive athletes' intentions to report doping misconduct. A second objective was to assess whether the effects of social norms on whistleblowing intentions were mediated by actor prototype evaluations and group identification and orientation.

Whistleblowing against doping in sport: A cross-national study on the effects of motivation and sportspersonship orientations on whistleblowing intentions.

Whistleblowing against anti-doping rule violations and related misconduct has been recognized as an important deterrent of doping behaviour in competitive sport. However, research on whistleblowing against doping is scarce and the available studies have focused on small samples using qualitative and inductive approaches. The present study used quantitative methods to assess, for the first time, the association between self-determined motivation, achievement goals, sportspersonship orientations and intentions to engage in whistleblowing against doping misconduct.

Physical Performance During the Menopausal Transition and the Role of Physical Activity.

Background: To examine longitudinal changes in physical performance during the menopausal transition and the role of physical activity (PA) in these changes.

Methods: Based on follicle-stimulating hormone levels and bleeding diaries, women (47-55 years) were classified as early (n = 89) and late perimenopausal (n = 143) and followed prospectively until postmenopausal status, with mean duration of 17.5 and 13.

Water Splitting and Transport of Ions in Electromembrane System with Bilayer Ion-Exchange Membrane.

Bilayer ion-exchange membranes are mainly used for separating single and multiply charged ions. It is well known that in membranes in which the layers have different charges of the ionogenic groups of the matrix, the limiting current decreases, and the water splitting reaction accelerates in comparison with monolayer (isotropic) ion-exchange membranes. We study samples of bilayer ion-exchange membranes with very thin cation-exchange layers deposited on an anion-exchange membrane-substrate in this work.

The role of physical activity in the link between menopausal status and mental well-being.

Objective: To examine the relationship between menopausal status and mental well-being, and whether this relationship varies as a function of physical activity (PA).

Methods: Based on a hormonal analysis and bleeding diary, women aged 47 to 55 were categorized as pre (n = 304), early peri (n = 198), late peri (n = 209), or postmenopausal (n = 387). Mental well-being was assessed using the Centre for Epidemiologic Studies Depression Scale, the International Positive and Negative Affect Schedule Short Form, and the Satisfaction with Life Scale.

Effortful verb retrieval from semantic memory drives beta suppression in mesial frontal regions involved in action initiation.

The contribution of the motor cortex to the semantic retrieval of verbs remains a subject of debate in neuroscience. Here, we examined whether additional engagement of the cortical motor system was required when access to verbs semantics was hindered during a verb generation task. We asked participants to produce verbs related to presented noun cues that were either strongly associated with a single verb to prompt fast and effortless verb retrieval, or were weakly associated with multiple verbs and more difficult to respond to.

Linear and Multi-Photon Fluorescence of Thiophene Based Copolymer with Electron-Accepting Side Chains.

A novel copolymer poly(thiophene-2,5-diyl-2,5-di-n-octyloxycarbonyl-1,4-phenylene), denoted as P33, is introduced as potential material for photovoltaics, polymer light-emitting diodes, and/or organic transistors. P33 dissolved in chloroform is investigated by steady-state absorption, linear/non-linear fluorescence spectroscopies and time-resolved fluorescence spectroscopy. Molar extinction coefficient, fluorescence quantum yield, and singlet fluorescence lifetime of P33 are determined to be 18,315 M cm, 0.

Physical performance in relation to menopause status and physical activity.

Objective: The aim of this study was to examine differences in physical performance (muscle power, muscle strength, aerobic capacity, and walking speed) across menopausal stages and potential of leisure physical activity (PA) to modify the impact of menopause on physical performance.

Methods: In this cross-sectional study, women aged 47 to 55 were randomly selected from the Finnish National Registry and categorized as premenopausal (n = 233), perimenopausal (n = 381), or postmenopausal (n = 299) based on serum concentrations of follicle-stimulating hormone and bleeding diary. Physical performance was measured by knee extension force, handgrip force, vertical jumping height, maximal walking speed, and 6-minute walking distance.

Simultaneous Processing of Noun Cue and to-be-Produced Verb in Verb Generation Task: Electromagnetic Evidence.

A long-standing but implicit assumption is that words strongly associated with a presented cue are automatically activated in the memory through rapid spread of activation within brain semantic networks. The current study was aimed to provide direct evidence of such rapid access to words' semantic representations and to investigate its neural sources using magnetoencephalography (MEG) and distributed source localization technique. Thirty-three neurotypical subjects underwent the MEG recording during verb generation task, which was to produce verbs related to the presented noun cues.
