Lipids from microorganisms, and especially lipids from Archaea, are used as taxonomic markers. Unfortunately, knowledge is very limited due to the uncultivability of most Archaea, which greatly reduces the importance of the diversity of lipids and their ecological role. One possible solution is to use lipidomic analysis. Six radioactive sources were investigated, two of which are surface (Wettinquelle and Radonka) and four deep from the Svornost mine (Agricola, Behounek, C1, and Curie). A total of 15 core lipids and 82 intact polar lipids were identified from the membranes of microorganisms in six radioactive springs. Using shotgun lipidomics, typical Archaea lipids were identified in spring water, namely dialkyl glycerol tetraethers, archaeol, hydroxyarchaeol and dihydroxyarchaeol. Diverse groups of polar heads were formed in archaeal IPLs, whose polar heads are formed mainly by hexose, deoxyhexose, and phosphoglycerol. The analysis was performed using shotgun lipidomics and the structure of all molecular species was confirmed by tandem mass spectrometry. After acid hydrolysis, a mixture of polar compounds was obtained from the polar head. Further analysis by GC-MS confirmed that the carbohydrates were glucose and rhamnose. Analysis by HPLC-MS of diastereoisomers of 2-(polyhydroxyalkyl)-3-(O-tolylthiocarbamoyl)thiazolidine-4(R)-carboxylates revealed that both L-rhamnose and D-glucose are present in spring samples only in varying amounts. The glycoside composition depends on the type of spring, that is, Wettinquelle and Radonka springs are basically shallow groundwater, while the samples from the Svornost mine are deep groundwater and do not contain glycosides with rhamnose. This method enables quick screening for characteristic Archaea lipids, allowing decisions on whether to pursue further analyses, such as metagenomic analysis, to directly confirm the presence of Archaea.

This scoping review summarizes evidence regarding the impact of civic and community engagement of young people during the COVID-19 pandemic. Recognizing that the global pandemic not only brought challenges but also new opportunities to take a stance and to actively engage in communities and society, this review assesses the impact of the COVID-19 pandemic on young people's civic engagement across different cultural contexts and identifies key factors and processes that enable young people to engage with their community or society at large. We summarize evidence from 27 original research papers, one thought piece, and four reports conducted by global organizations such as the United Nations and OECD. Relevant research was conducted in the United States, Europe, China, Southeast Asia, South Africa, and New Zealand, addressing the development of leadership skills, civic responsibility, critical consciousness, civic and community engagement, as well as social integration. Key factors that facilitated civic engagement include national investments in online learning facilities, support for basic needs (such as education, health, and employment), and promotion and encouragement of local initiatives. The studies differed in their focus depending on the socio-cultural context encountered and future research needs to consider cultural variations and different demands on young people to inform effective practices for supporting young people's active engagement in society.

TFE3 rearrangements characterize histogenetically, topographically, and biologically diverse neoplasms. Besides being a universal defining feature in alveolar soft part sarcoma (ASPS) and clear cell stromal tumor of the lung, TFE3 fusions have been reported in subsets of renal cell carcinoma, perivascular epithelioid cell tumor (PEComa), epithelioid hemangioendothelioma and ossifying fibromyxoid tumors. TFE3 -related neoplasms are rare in the head and neck and may pose diagnostic challenges. We herein describe 22 TFE3 fusion neoplasms affecting 11 males and 11 females aged 4 to 79 years (median, 25) and involving different head and neck sites: sinonasal cavities (n = 8), tongue (n = 4), oral cavity/oropharynx (n = 3), salivary glands (n = 2), orbit (n = 2), and soft tissue or unspecified sites (n = 3). Based on morphology and myomelanocytic immunophenotype, 10 tumors qualified as ASPS, 7 as PEComas (3 melanotic; all sinonasal), and 5 showed intermediate (indeterminate) histology overlapping with ASPS and PEComa. Immunohistochemistry for TFE3 was homogeneously strongly positive in all cases. Targeted RNA sequencing/FISH testing confirmed TFE3 fusions in 14 of 16 successfully tested cases (88%). ASPSCR1 was the most frequent fusion partner in ASPS (4 of 5 cases); one ASPS had a rare VCP::TFE3 fusion. The 6 successfully tested PEComas had known fusion partners as reported in renal cell carcinoma and PEComas ( NONO, PRCC, SFPQ , and PSPC1 ). The indeterminate tumors harbored ASPSCR1::TFE3 (n = 2) and U2AF2::TFE3 (n = 1) fusions, respectively. This large series devoted to TFE3-positive head and neck tumors illustrates the recently proposed morphologic overlap in the spectrum of TFE3 -associated mesenchymal neoplasms. While all PEComas were sinonasal, ASPS was never sinonasal and occurred in diverse head and neck sites with a predilection for the tongue. The indeterminate (PEComa-like) category is molecularly more akin to ASPS but shows different age, sex, and anatomic distribution compared with classic ASPS. We report VCP as a novel fusion partner in ASPS and PSPC1 as a novel TFE3 fusion partner in PEComa (detected in one PEComa). Future studies should shed light on the most appropriate terminological subtyping of these highly overlapping tumors.

The 2024 Kidney Disease: Improving Global Outcomes (KDIGO) guidelines for chronic kidney disease (CKD) evaluation and management bring important updates, particularly for European laboratories. These guidelines emphasize the need for harmonization in CKD testing, promoting the use of regional equations. In Europe, the European Kidney Function Consortium (EKFC) equation is particularly suited for European populations, particularly compared to the CKD-EPI 2021 race-free equation. A significant focus is placed on the combined use of creatinine and cystatin C to estimate glomerular filtration rate (eGFRcr-cys), improving diagnostic accuracy. In situations where eGFR may be inaccurate or clinically insufficient, the guidelines encourage the use of measured GFR (mGFR) through exogenous markers like iohexol. These guidelines emphasize the need to standardize creatinine and cystatin C measurements, ensure traceability to international reference materials, and adopt harmonized reporting practices. The recommendations also highlight the importance of incorporating risk prediction models, such as the Kidney Failure Risk Equation (KFRE), into routine clinical practice to better tailor patient care. This article provides a European perspective on how these KDIGO updates should be implemented in clinical laboratories to enhance CKD diagnosis and management, ensuring consistency across the continent.

OBJECTIVES: Mindfulness-based interventions (MBIs) for persons with dementia (PwD) have yielded mixed results, possibly attributable to the fact that little is known about the validity and reliability of trait mindfulness self-report measures in PwD. This narrative review sought to identify studies involving self-reported trait mindfulness and other clinical measures that may hold information on the convergent validity and reliability of these measures in PwD. METHODS: Scientific databases were searched for studies involving PwD and mindfulness assessments. RESULTS: N = 426 studies from PubMed and N = 156 from PsychInfo databases were reviewed. Four cross-sectional studies were identified that allowed inferences about the validity of mindfulness measures. A qualitative review indicated that convergent validity with other measures varied with sample heterogeneity and cognitive impairment. Merely one MBI included self-reported trait mindfulness, however without reporting sample-specific validity or reliability. CONCLUSIONS: Despite efforts to implement MBIs in PwD, information on basic methodological psychometric issues is minimal. Future studies ought to address the validity and reliability of self-reported mindfulness in detail across different stages of dementia. CLINICAL IMPLICATIONS: Results of MBIs need to be considered cautiously. Basic information about psychometric properties of mindfulness self-report measures is required and these measures need to be included systematically in MBIs.

PURPOSE: While anal cancer is a very rare oncological diagnosis representing less than 2% of lower gastrointestinal tract cancers, the incidence has doubled in the past 20 years. Radical radiochemotherapy with sequential or simultaneous boost is now the standard treatment modality. Interstitial HDR brachytherapy is one of the boost application options. Implementation of new radiotherapy techniques has resulted in improved therapeutic outcomes; however, it is still associated with acute and especially late toxicity. Gastrointestinal disorders and sexual dysfunction are the most frequent factors affecting the long-term quality of cured patients' lives. METHODS: A total of 96 patients consecutively treated between 2000 and 2022 with external beam radio-/chemotherapy and an interstitial brachytherapy boost for histologically verified nonmetastatic anal squamous cell carcinoma were evaluated. The median follow-up time was 15.4 years (range 13.4-17.3 years). The primary objective of the study was to assess local control (LC) and quality of life (QoL). The Czech versions of internationally validated EORTC questionnaires were used to evaluate life quality-the basic EORTC QOL-C30 v.3 and the specific QOL-ANL 27 questionnaire. RESULTS: Local control was 85.5% at 5 years, 83.4% at 10 years, 83.4% at 15 years, and 83.4% at 20 years, and there was no dependence on clinical stage. The most common forms of acute toxicity were cutaneous and hematological but were gastrointestinal for late toxicities. In the evaluation of quality of life, 80.5% of patients alive at the time participated. In the EORTC quality of life questionnaire C30 v.3, patients rated the functional scale score as 86.2 points (standard deviation [SD] = 12.6) and the symptom score as 15.5 points (SD = 12.5). The global health score achieved 68.4 points (SD = 23.6). The most common symptoms were fatigue with 25.6 points (SD = 20.2) and diarrhea with 19.0 points (SD = 27.8). In the QOL-ANL 27 questionnaire, symptom scales assessing bowel symptoms were scored 27.5 points (SD = 19) in non-stoma patients and 11.9 points (SD = 17.2) in stoma patients. In the single-item symptom scales, the highest scores were rated for frequency of urination with 26.4 points (SD = 30.8), need to be close to a toilet with 22.4 points (SD = 27.3), and self-cleaning more often with 25.3 points (SD = 31.8). In the functional scales assessing sex life and interest, men and women reported scores of 45.2 (SD = 23) and 45.5 points (SD = 19), respectively. CONCLUSION: Boost with interstitial HDR brachytherapy is an established safe method of anal cancer treatment, with excellent results and limited late toxicity. Functioning scales were rated relatively highly in QoL questionnaires, and the overall global health score was comparable to published data. Gastrointestinal difficulties, fatigue, and sexual dysfunction dominated the symptom scales in our cohort.

PURPOSE OF REVIEW: A critical evaluation of contemporary literature regarding the role of big data, artificial intelligence, and digital technologies in precision cardio-oncology care and survivorship, emphasizing innovative and groundbreaking endeavors. RECENT FINDINGS: Artificial intelligence (AI) algorithm models can automate the risk assessment process and augment current subjective clinical decision tools. AI, particularly machine learning (ML), can identify medically significant patterns in large data sets. Machine learning in cardio-oncology care has great potential in screening, diagnosis, monitoring, and managing cancer therapy-related cardiovascular complications. To this end, large-scale imaging data and clinical information are being leveraged in training efficient AI algorithms that may lead to effective clinical tools for caring for this vulnerable population. Telemedicine may benefit cardio-oncology patients by enhancing healthcare delivery through lowering costs, improving quality, and personalizing care. Similarly, the utilization of wearable biosensors and mobile health technology for remote monitoring holds the potential to improve cardio-oncology outcomes through early intervention and deeper clinical insight. Investigations are ongoing regarding the application of digital health tools such as telemedicine and remote monitoring devices in enhancing the functional status and recovery of cancer patients, particularly those with limited access to centralized services, by increasing physical activity levels and providing access to rehabilitation services. SUMMARY: In recent years, advances in cancer survival have increased the prevalence of patients experiencing cancer therapy-related cardiovascular complications. Traditional cardio-oncology risk categorization largely relies on basic clinical features and physician assessment, necessitating advancements in machine learning to create objective prediction models using diverse data sources. Healthcare disparities may be perpetuated through AI algorithms in digital health technologies. In turn, this may have a detrimental effect on minority populations by limiting resource allocation. Several AI-powered innovative health tools could be leveraged to bridge the digital divide and improve access to equitable care.

BACKGROUND: Ice hockey is a dynamic game. We can observe collisions between the players that bring a risk of injury. There are many hockey clubs in the Czech Republic. These clubs raise great hockey players and many competing players in various levels of national leagues. The aim of this study was to map injuries in Czech hockey players and outline the situation of injury prevention and body care in ice hockey players. METHODS: We used a questionnaire survey method to obtain data. We received answers from 100 male active Czech ice hockey players, playing in the top three highest men's competitions (Extraleague - 2nd league). Individual injuries were analyzed according to specific body parts, injury type, playing position, level of competition using basic statistical characteristics and relative frequency analyses, including the recovery time, injury reason and the injury statistics per 1000 sporting performances in ice hockey. RESULTS: We found that 81% of participants suffered injuries with the overall incidence of injuries was 17.1 per 1000 sports performances and mainly happened during the match compared to training. The most common injuries were in the head and neck area (25%), often caused by a collision with another player, a stick or puck hit, or a collision with a board. Other frequently injured parts were the knees (21%), where internal ligament injuries predominate, and the shoulders (20%), where we recorded mainly ligament injuries. CONCLUSIONS: There is a high risk of various injury types of ice hockey players, that are developed accidentally in all body parts mostly in the match (mostly upper part of the body and knee) or by overloading (hip/groin area). We recommend strategies to avoid or minimize the injury risk of players. The hockey clubs, coaches, and players should extensively and regularly cooperate with physiotherapists, starting from the younger age of hockey groups, to prevent injuries and use regular strengthening of crucial muscle parts, regeneration, and compensatory exercises. We endorse adequately evaluating dangerous foul actions for referees and disciplinary officials also in minor competitions.

BACKGROUND: In refractory cardiac arrest, extracorporeal cardiopulmonary resuscitation may increase the survival chance. However, in cases of unsuccessful treatment, extracorporeal cardiopulmonary resuscitation may additionally provide an important source of organ donors. Therefore, we hypothesized that implementing extracorporeal cardiopulmonary resuscitation service into a high-volume cardiac arrest center's routine would increases organ donors' availability. METHODS: Our retrospective observational study analyzed out-of-hospital cardiac arrest patients admitted to the General University Hospital in Prague between 2007 and 2020. The following groups were analyzed regarding the recruitment of donors: before and after extracorporeal cardiopulmonary resuscitation implementation. We assessed the number of donors referred, the number of organs harvested, and the organ's survival. RESULTS: We analyzed the results of 1,158 patients after out-of-hospital cardiac arrest. In the conventional approach period, 11 donors were referred, of which 7 were accepted. During the extracorporeal cardiopulmonary resuscitation period, the number of donors increased to 80, of whom 42 were accepted. The number of donated organs was 18 and 119 in the respective periods, corresponding to 3.6 vs 13.2 (p = 0.033) harvested organs per year. One-year survival of transplanted organs was 94.4% vs 99.2%, and 5-year survival was 94.4% vs 95.9% in relevant periods. Conventional and extracorporeal cardiopulmonary resuscitation did not affect donor organ survival. CONCLUSION: Establishing a high-volume cardiac arrest center providing an extracorporeal cardiopulmonary resuscitation service may increase not only the number of prolonged cardiac arrest survivors but also the number of organ donors. In addition, the performances of donated organs were high and comparable between both treatment methods.

Across the globe, significant inequities in brain tumor treatment, care, and support perpetuate. Identifying and addressing these unmet needs in the context of patients' rights is crucial to reducing inequalities and improving outcomes for people living with brain tumors. Brain tumor patient advocacy addresses and influences gaps in healthcare provision, ensuring optimal treatment, care, and support for patients, their caregivers, and families. Therefore, the purpose of this review is to highlight the variety of challenges faced by brain tumor patients, caregivers, and advocates in various parts of the world and set a benchmark for improvements. Twenty-eight leading brain tumor patient/caregiver advocates from 18 countries in Asia Pacific, Sub-Saharan Africa, North America, Eastern Europe, and Western Europe collaborated to explore unmet and met needs in their countries. Virtual meetings were held with the 5 geographic groupings. Through a process of discussion based on a combination of patient advocates' informed expert opinion, published references, a survey (Asia Pacific) and the informal completion of a matrix of challenges by some of the advocacy organizations involved, agreement within the groupings was also reached regarding what rights within The Brain Tumor Patients' Charter of Rights they felt were being met and where there are still gaps. Acknowledging that some rights in The Brain Tumor Patients' Charter of Rights are aspirational, there still remain many areas of the world where even basic patient rights are not yet attainable. Patient advocacy organizations stand ready to help change this to achieve the best possible health and quality of life outcomes for adults and children living with brain tumors.
