Differences in lung function, bronchial hyperresponsiveness and respiratory health between elite athletes competing in different sports

ABSTRACT The aim of this study was to examine lung function, bronchial hyperresponsiveness (BHR) and exercise-induced respiratory symptoms in elite athletes performing different sports. Norwegian national-team athletes (30 swimmers, 32 cross-country skiers, 16 speed-skaters, 11 rowers/paddlers, 17 handball players and 23 soccer players) completed a validated questionnaire, measured exhaled nitric oxide (FENO), spirometry, methacholine provocation (PD20met) and skin prick test. Three cut-off levels defined BHR; i.e. PD20met ≤2 µmol, ≤4 µmol and ≤8 µmol. Mean forced vital capacity (FVC) was highest in swimmers (Mean z-score[95%CI] = 1.16 [0.80, 1.51]), and close to or higher than reference values according to the Global Lung Initiative equation, across all sports. Mean forced expiratory volume in 1 s (FEV1) was higher than reference values in swimmers (0.48 [0.13, 0.84]), and ball game athletes (0.69 [0.41, 0.97]). Mean forced expiratory flow between 25 and 75% of FVC (FEF25-75), and/or FEV1/FVC were lower than reference values in all endurance groups. BHR defined by ≤2 and ≤8 µmol methacholine was observed in respectively 50%–87% of swimmers, 25%–47% of cross-country skiers, 20%–53% of speed-skaters, 18%–36% of rowers/paddlers, and 0%–17% of the ball game athletes. Exercise-induced symptoms were common in all groups, most frequent in cross-country skiers (88%), swimmers (83%) and speed-skaters (81%). Highlights Swimmers and ball game athletes had higher mean FVC and FEV1 when compared to the reference values predicted by the Global Lung Initiative (GLI) reference equation. Contrasting this, across all sports except ball game athletes, mean FEF25-75 and/or FEV1/FVC were lower than reference values. The prevalence of bronchial hyperresponsiveness (BHR) was high among elite athletes competing in swimming, cross-country skiing, speed skating and rowing/paddling, with swimmers being most affected. The majority of the elite athletes reported exercise-induced respiratory symptoms independent of lung function or BHR.

1Department of Neurosurgery, Chongqing Red Cross Hospital (People’s Hospital of Jiangbei District), Jiangbei, Chongqing 400020, People’s Republic of China; 2Department of Rehabilitation Medicine, Guizhou Provincial People’s Hospital, Guiyang, Guizhou 550002, People’s Republic of China Purpose: Traumatic brain injury (TBI) is a major cause of morbidity and mortality worldwide. Increasing evidence indicates that activated microglia play an important role in the inflammatory response in TBI. Inhibiting M1 and stimulating M2 activated microglia have protective effects in several animal models of central nervous system (CNS) disorders. In the present study, we investigated whether tanshinone IIA (TNA) protects neurons by shifting microglia polarization in a mouse TBI model and further investigated the mechanism in vitro. Materials and Methods: Forty C57BL/6 mice were used to investigate the effect of TNA on microglia polarization in TBI. BV-2 cells were used to examine the mechanism of TNA in regulating microglia polarization. Results: Normal saline (NS), TNA and the combination of TNA with ICI 182,780 (ICI, an estrogen receptor antagonist) were used to treat the TBI mice. After TBI, mice from each group demonstrated functional improvement. The improvement rate in mice treated with TNA was faster than other groups. ICI partially reversed the benefits from TNA treatment. TNA treatment significantly reduced TBI-induced neuronal loss. The number of microglia after TBI was not significantly changed by TNA treatment. However, TNA treatment significantly decreased M1 macrophage markers (iNOS, TNFα and IL-1β) and increased M2 macrophage markers (CD206, arginase 1 and Ym1). This effect was partially abolished by ICI. TNA treatment downregulated M1 macrophage markers and upregulated M2 macrophage markers in BV-2 cells under LPS stimulation. IL-10 was significantly increased by TNA treatment without a significantly change of IL-4 and IL-13 expression. IL-10 knockdown completely abolished the effect of TNA on microglial M2 polarization. Conclusion: Taken together, our data demonstrated that TNA attenuates neuronal loss in mouse TBI model and promotes M2 microglia by ERβ/IL-10 pathway. Thus, TNA could be a potential drug for TBI and/or the disorders that caused by microglial over-activation in CNS.
Cervical cancer survivors: The experiences of the journey.

OBJECTIVE Cervical cancer affects survivors' overall coping. Yet, specifically emotional and behavioral expression patterns among cervical cancer survivors have barely been examined. In addition, no study has focused on survivors' experiences of sequences related to coping. Understanding these perceptions can help provide a tailored response and improve psycho-social interventions. The aim of this study was to gain a better understanding of the emotional and behavioral motives involved in coping with cervical cancer recovery. METHODS Qualitative interviews were conducted with 15 survivors of cervical cancer (stages I and II), using a semi-structured in-depth questionnaire. The interviews were recorded, transcribed, and analyzed by three researchers using thematic analysis. RESULTS Six main themes emerged: (i) Reasons and benefits for keeping the disease a secret or sharing it with others; (ii) "When you get used to despair, there's also room for hope": Despair alongside hope; (iii) Self-guilt following the disease, but also knowing how to forgive yourself; (iv) Deep loneliness alongside a significant need for support; (v) Finding the way from passivity to activity; and (vi) When meaning in life is missing, and the importance of meaning when it is present. There was a balance between negative emotions and behaviors (despair, confidentiality, guilt, loneliness, passivity, lack of meaning) and positive emotions and behaviors (hope, openness, forgiveness, significant support, activity, meaning). SIGNIFICANCE OF THE RESULTS The study revealed that in some cases cervical cancer coping during the recovery period moves across sequences. The women's narratives portray past difficulties as the reason for present psychological health, and their experience of a healthy present is intensified by their past difficulties. Implications for practice are discussed.
Hepatocellular carcinoma and its impact on quality of life: A review of the qualitative literature

Abstract Introduction Hepatocellular carcinoma (HCC) carries significant burden of disease, with high mortality rates and poor prognosis. It is therefore important to consider quality of life (QoL) for patients with HCC. Quantitative research assesses HCC and QoL via standardised measurement tools, but these do not capture the full scope of patient experiences. This review examines the body of qualitative research on this topic, to develop a comprehensive understanding of QoL for this population. Methods Medline, EMBASE and PsycINFO were systematically searched with keywords relating to HCC, QoL and patient experience. After applying inclusion and exclusion criteria, key findings of included studies were extracted and analysed for themes. Results Eleven studies were included for thematic analysis, with five themes identified as central to QoL: (1) burden of physical symptoms and treatment side effects; (2) psychological impact and coping strategies; (3) social function and stigma; (4) spiritual wellbeing, sense of self and meaning of illness and (5) pervasive uncertainty. Conclusion HCC profoundly impacted patients' lives, spanning physical, psychological, social and spiritual QoL domains. While QoL was reduced overall, some features of patient experiences that enhanced QoL were noted. The findings complement data from quantitative studies, helping to build a richer understanding of QoL.
Mediating role for metacognitive processes in the relationship between schizotypy and anxiety and depression symptoms

ABSTRACT Introduction: Depression and anxiety symptoms are highly prevalent in schizophrenia-spectrum disorders and are commonly associated with schizotypy in non-clinical samples. However, it remains unclear what factors could be contributing to the relationships between schizotypy and anxiety and depression symptoms. Using path analysis, we explored the complex interplay between schizotypy, metacognitive beliefs, cognitive insight, and symptoms of emotional distress. Methods: Self-report data of schizotypy, metacognitive beliefs, cognitive insight, depression, and anxiety symptoms were collected from 344 participants from a predominantly student sample. Results: Path analysis confirmed unique associations between schizotypy dimensions, metacognitive beliefs, and cognitive insight. Furthermore, negative beliefs about worry mediated the link between the schizotypy dimensions, unusual experiences, cognitive disorganisation, and introvertive anhedonia and both depression and anxiety symptoms. Lack of cognitive confidence also mediated the relationship between cognitive disorganisation and depression symptoms. Finally, the cognitive insight subcomponent self-reflectiveness mediated the relationship between unusual experiences and cognitive disorganisation and anxiety. Conclusions: This study significantly furthers our understanding of the complex relationship between schizotypy, metacognitive processes, and emotional distress. Our findings also provide support for interventions which modify metacognitive beliefs and self-reflectiveness, which may prove beneficial for treatment in clinical settings.
The value of Phosphohistone H3 as a cell proliferation marker in oral squamous cell carcinoma. A comparative study with Ki-67 and the mitotic activity index

Background The Phosphohistone H3 (PHH3) antibody is recognized as a biomarker of cell proliferation, specific for cells in mitosis, of prognostic value in different malignant neoplasms, however it has been poorly studied in oral squamous cell carcinoma (OSCC). The main objective of this study was to evaluate the immunoexpression of the PHH3 in the OSCC, through the correlation with the immunoexpression of Ki-67, the mitotic activity index (MAI), histological grading, clinical-morphological parameters and the rate of survival. Material and Methods The study sample consisted of 62 cases of OSCC diagnosed in the Pathological Anatomy Laboratory of the Faculty of Dentistry, University of the Republic (Uruguay). In each of them, an immunohistochemical technique was performed for Ki-67 and PHH3 (serine 10) antibodies. Image J software was used for the MAI and biomarker quantification, defining the percentage of positivity and mitotic Figures per 1000 tumor cells. Results a significant association was obtained between the expression of PHH3 (p 0.016) and MAI (p 0.031) with survival time. However, no similar relationship was found with Ki-67 (p 0.295). Although it was confirmed a statistical association between histological grade and Ki-67 immunoexpression (p 0.004), PHH3 did not show a similar relationship (p 0.564). Conclusions It was confirmed the role of the PHH3 antibody as a biomarker of mitotic Figures in OSCC and as a potential marker of cell proliferation. It is noteworthy that this is one of the first works that evaluates a possible relationship between the expression of this antibody and survival in OSCC. Key words:Oral squamous cell carcinoma, phosphohistone H3, Ki-67, cell proliferation.
Symptom Number and Reduced Preinfection Training Predict Prolonged Return to Training after SARS-CoV-2 in Athletes: AWARE IV

ABSTRACT Purpose This study aimed to determine factors predictive of prolonged return to training (RTT) in athletes with recent SARS-CoV-2 infection. Methods This is a cross-sectional descriptive study. Athletes not vaccinated against COVID-19 (n = 207) with confirmed SARS-CoV-2 infection (predominantly ancestral virus and beta-variant) completed an online survey detailing the following factors: demographics (age and sex), level of sport participation, type of sport, comorbidity history and preinfection training (training hours 7 d preinfection), SARS-CoV-2 symptoms (26 in 3 categories; “nose and throat,” “chest and neck,” and “whole body”), and days to RTT. Main outcomes were hazard ratios (HR, 95% confidence interval) for athletes with versus without a factor, explored in univariate and multiple models. HR < 1 was predictive of prolonged RTT (reduced % chance of RTT after symptom onset). Significance was P < 0.05. Results Age, level of sport participation, type of sport, and history of comorbidities were not predictors of prolonged RTT. Significant predictors of prolonged RTT (univariate model) were as follows (HR, 95% confidence interval): female (0.6, 0.4–0.9; P = 0.01), reduced training in the 7 d preinfection (1.03, 1.01–1.06; P = 0.003), presence of symptoms by anatomical region (any “chest and neck” [0.6, 0.4–0.8; P = 0.004] and any “whole body” [0.6, 0.4–0.9; P = 0.025]), and several specific symptoms. Multiple models show that the greater number of symptoms in each anatomical region (adjusted for training hours in the 7 d preinfection) was associated with prolonged RTT (P < 0.05). Conclusions Reduced preinfection training hours and the number of acute infection symptoms may predict prolonged RTT in athletes with recent SARS-CoV-2. These data can assist physicians as well as athletes/coaches in planning and guiding RTT. Future studies can explore whether these variables can be used to predict time to return to full performance and classify severity of acute respiratory infection in athletes.
Nephroprotective effect of exercise training in cisplatin-induced renal damage in mice: influence of training protocol

Cisplatin is an effective antineoplastic agent, but its use is limited by its nephrotoxicity caused by the oxidative stress in tubular epithelium of nephrons. On the other hand, regular exercise provides beneficial adaptations in different tissues and organs. As with many drugs, dosing is extremely important to get the beneficial effects of exercise. Thus, we aimed to investigate the influence of exercise intensity and frequency on cisplatin-induced (20 mg/kg) renal damage in mice. Forty male Swiss mice were divided into five experimental groups (n=8 per group): 1) sedentary; 2) low-intensity forced swimming, three times per week; 3) high-intensity forced swimming, three times per week; 4) low-intensity forced swimming, five times per week; and 5) high-intensity forced swimming, five times per week. Body composition, renal structure, functional indicators (plasma urea), lipid peroxidation, antioxidant enzyme activity, expression of genes related to antioxidant defense, and inflammatory and apoptotic pathways were evaluated. Comparisons considered exercise intensity and frequency. High lipid peroxidation was observed in the sedentary group compared with trained mice, regardless of exercise intensity and frequency. Groups that trained three times per week showed more benefits, as reduced tubular necrosis, plasma urea, expression of CASP3 and Rela (NFkB subunit-p65) genes, and increased total glutathione peroxidase activity. No significant difference in Nfe2l2 (Nrf2) gene expression was observed between groups. Eight weeks of regular exercise training promoted nephroprotection against cisplatin-mediated oxidative injury. Exercise frequency was critical for nephroprotection.
Engineering a dynamic three-dimensional cell culturing microenvironment using a ‘sandwich’ structure-liked microfluidic device with 3D printing scaffold

Most of in vivo tissue cells reside in 3D extracellular matrix (ECM) with fluid flow. To better study cell physiology and pathophysiology, there has been an increasing need in the development of methods for culturing cells in in vivo like microenvironments with a number of strategies currently being investigated including hydrogels, spheroids, tissue scaffolds and very promising microfluidic systems. In this paper, a ‘sandwich’ structure-liked microfluidic device integrated with a 3D printing scaffold is proposed for three-dimensional and dynamic cell culture. The device consists of three layers, i.e. upper layer, scaffold layer and bottom layer. The upper layer is used for introducing cells and fixing scaffold, the scaffold layer mimicking ECM is used for providing 3D attachment areas, and the bottom layer mimicking blood vessels is used for supplying dynamic medium for cells. Thermally assisted electrohydrodynamic jet (TAEJ) printing technology and microfabrication technology are combined to fabricate the device. The flow field in the chamber of device is evaluated by numerical simulation and particle tracking technology to investigate the effects of scaffold on fluid microenvironment. The cell culturing processes are presented by the flow behaviors of inks with different colors. The densities and viabilities of HeLa cells are evaluated and compared after 72 h of culturing in the microfluidic devices and 48-well plate. The dose-dependent cell responses to doxorubicin hydrochloride (DOX) are observed after 24 h treatment at different concentrations. These experimental results, including the evaluation of cell proliferation and in vitro cytotoxicity assessment of DOX in the devices and plate, demonstrate that the presented microfluidic device has good biocompatibility and feasibility, which have great potential in providing native microenvironments for in vitro cell studies, tissue engineering and drug screening for tumor therapy.
Behavioral stability of alcohol consumption and socio-demographic correlates of change among a nationally representative cohort of US adults

Aims: To estimate the probability of transitioning between different categories of alcohol use (drinking states) among a nationally representative cohort of United States (US) adults and to identify the effects of socio-demographic characteristics on those transitions. Design, setting and participants: Secondary analysis of data from the National Epidemiologic Survey of Alcohol and Related Conditions (NESARC), a prospective cohort study conducted in 2001–02 and 2004–05; a US nation-wide, population-based study. Participants included 34 165 adults (mean age = 45.1 years, standard deviation = 17.3; 52% women). Measurements: Alcohol use was self-reported and categorized based on the grams consumed per day: (1) non-drinker (no drinks in past 12 months), (2) category I (women = ≤ 20; men = ≤ 40), (3) category II (women = 21–40; men = 41–60) and (4) category III (women = ≥ 41; men = ≥ 61). Multi-state Markov models estimated the probability of transitioning between drinking states, conditioned on age, sex, race/ethnicity and educational attainment. Analyses were repeated with alcohol use categorized based on the frequency of heavy episodic drinking. Findings: The highest transition probabilities were observed for staying in the same state; after 1 year, the probability of remaining in the same state was 90.1% [95% confidence interval (CI) = 89.7%, 90.5%] for non-drinkers, 90.2% (95% CI = 89.9%, 90.5%) for category I, 31.8% (95% CI = 29.7, 33.9%) category II and 52.2% (95% CI = 46.0, 58.5%) for category III. Women, older adults, and non-Hispanic Other adults were less likely to transition between drinking states, including transitions to lower use. Adults with lower educational attainment were more likely to transition between drinking states; however, they were also less likely to transition out of the ‘weekly HED’ category. Black adults were more likely to transition into or stay in higher use categories, whereas Hispanic/Latinx adults were largely similar to White adults. Conclusions: In this study of alcohol transition probabilities, some demographic subgroups appeared more likely to transition into or persist in higher alcohol consumption states.
The photosynthesis apparatus of European mistletoe (Viscum album)

Abstract European mistletoe (Viscum album) is known for its special mode of cellular respiration. It lacks the mitochondrial NADH dehydrogenase complex (Complex I of the respiratory chain) and has restricted capacities to generate mitochondrial adenosine triphosphate (ATP). Here, we present an investigation of the V. album energy metabolism taking place in chloroplasts. Thylakoids were purified from young V. album leaves, and membrane-bound protein complexes were characterized by Blue native polyacrylamide gel electrophoresis as well as by the complexome profiling approach. Proteins were systematically identified by label-free quantitative shotgun proteomics. We identified >1,800 distinct proteins (accessible at https://complexomemap.de/va_leaves), including nearly 100 proteins forming part of the protein complexes involved in the light-dependent part of photosynthesis. The photosynthesis apparatus of V. album has distinct features: (1) comparatively low amounts of Photosystem I; (2) absence of the NDH complex (the chloroplast pendant of mitochondrial Complex I involved in cyclic electron transport (CET) around Photosystem I); (3) reduced levels of the proton gradient regulation 5 (PGR5) and proton gradient regulation 5-like 1 (PGRL1) proteins, which offer an alternative route for CET around Photosystem I; (4) comparable amounts of Photosystem II and the chloroplast ATP synthase complex to other seed plants. Our data suggest a restricted capacity for chloroplast ATP biosynthesis by the photophosphorylation process. This is in addition to the limited ATP supply by the mitochondria. We propose a view on mistletoe’s mode of life, according to which its metabolism relies to a greater extent on energy-rich compounds provided by the host trees.
Development of Medication Administration Protocols for In-Home Pediatric Feeding Cases

Medication administration can be a significant issue in pediatric populations, and especially with patients with developmental disabilities and comorbid feeding disorders. Research has focused largely on consumption of solids rather than medication and liquids in pediatric feeding programs, with most studies being conducted within specialized hospital settings in the United States. No studies to our knowledge have detailed treatment evaluations for medication administration in pediatric feeding except for a few studies on pill swallowing. We report results of treatment protocols for medication administration using empirically-supported treatments in a short-term intensive home-based behavior-analytic program in Australia. Two males with autism spectrum and pediatric feeding disorders participated. We used a multiple baseline single-case experimental design for medication administration conducted concurrently with a treatment evaluation for solid foods. Consumption increased in number (9; supplements, laxatives, pain relievers), flavors (8; chocolate, blackcurrent and apple, strawberry, lemon-lime, orange, chocolate-vanilla, cherry, apple), forms (4; thin and thick liquids, chewables, gummies), and delivery methods (5; finger-fed, spoon, cup, medicine spoon, medicine cup) within the first treatment session. For one participant, we taught open cup drinking for a variety of liquids (milk, juices, medications). For both participants, we taught self-feeding with utensils for thick liquid medications. Treatment results were similar for solids and participants increased food variety to over 160 across food groups. All goals were met including training parents to maintain gains at home.
