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.

OBJECTIVES: The development of External Quality Assessment Schemes (EQAS) for clinical flow cytometry (FCM) is challenging in the context of rare (immunological) diseases. Here, we introduce a novel EQAS monitoring the primary immunodeficiency Orientation Tube (PIDOT), developed by EuroFlow, in both a 'wet' and 'dry' format. This EQAS provides feedback on the quality of individual laboratories (i.e., accuracy, reproducibility and result interpretation), while eliminating the need for sample distribution. METHODS: In the wet format, marker staining intensities (MedFIs) within landmark cell populations in PIDOT analysis performed on locally collected healthy control (HC) samples, were compared to EQAS targets. In the dry format, participants analyzed centrally distributed PIDOT flow cytometry data (n=10). RESULTS: We report the results of six EQAS rounds across 20 laboratories in 11 countries. The wet format (212 HC samples) demonstrated consistent technical performance among laboratories (median %rCV on MedFIs=34.5 %; average failure rate 17.3 %) and showed improvement upon repeated participation. The dry format demonstrated effective proficiency of participants in cell count enumeration (range %rCVs 3.1-7.1 % for the major lymphoid subsets), and in identifying lymphoid abnormalities (79.3 % alignment with reference). CONCLUSIONS: The PIDOT-EQAS allows laboratories, adhering to the standardized EuroFlow approach, to monitor interlaboratory variations without the need for sample distribution, and provides them educational support to recognize rare clinically relevant immunophenotypic patterns of primary immunodeficiencies (PID). This EQAS contributes to quality improvement of PID diagnostics and can serve as an example for future flow cytometry EQAS in the context of rare diseases.
BACKGROUND: To predict worsening heart failure hospitalizations (WHFHs), the HeartInsight multiparametric algorithm calculates a heart failure (HF) Score based on temporal trends of physiologic parameters obtained through automatic daily remote monitoring of implantable cardioverter-defibrillators (ICDs). OBJECTIVE: We studied the association of the baseline HF Score, determined at algorithm activation, with long-term patient outcomes. METHODS: Data from 9 clinical trials were pooled, including 1841 ICD patients with a preimplantation ejection fraction ≤35%, New York Heart Association class II/III, and no long-standing atrial fibrillation. The primary end point was a composite of death or WHFH. RESULTS: After a median follow-up of 631 days (interquartile range, 385-865 days), there were 243 WHFHs in 173 patients (9.4%) and 122 deaths (6.6%), 52 of which (42.6%) were cardiovascular. The primary end point occurred in 265 patients (14.4%). A multivariable time-to-first-event analysis showed that a high baseline HF Score (>23, as determined by a time-dependent receiver operating characteristics curve analysis) was significantly associated with the occurrence of the primary end point (adjusted hazard ratio [HR], 2.05; 95% confidence interval [CI], 1.54-2.71; P < .0001), all-cause death (HR, 2.37; CI, 1.56-3.58; P < .0001), cardiovascular death (HR, 2.19; CI, 1.14-4.22; P = .019), and WHFH (HR, 1.91; CI, 1.35-2.71; P = .0003). In a hierarchical event analysis of all-cause death as the outcome with highest priority and WHFHs as repeated event outcomes, the win ratio was 2.47 (CI, 1.89-3.24; P < .0001). CONCLUSION: Based on a retrospective analysis of clinical trial data with adjudicated events, baseline HF Score derived from device-monitored variables was able to stratify patients at higher long-term risk of death or WHFH.

The forskolin-induced swelling assay (FIS) in patient-derived intestinal organoids (PDIOs), used to determine in vitro responsiveness to elexacaftor/tezacaftor/ivacaftor (ETI), showed variability in swelling among PDIOs obtained from people with CF (pwCF) carrying the same F508del/F508del CFTR genotype. We aimed to characterise the effect of ETI on the transcriptional activity of PDIOs-derived cells to understand the intracellular processes triggered by ETI and the differences in treatment response. Six high- and six low-responding PDIOs to ETI, derived from F508del/F508del pwCF, were incubated with or without ETI for 2 to 6 h. Gene expression was assessed using 3'-mRNA sequencing and modelled using negative binomial models. Incubation with ETI resulted in a significant upregulation of several biological processes: mostly related to chemokines and signalling, chemotaxis, and tissue development processes. No changes were observed in abundance of the CFTR transcripts or in CFTR-related gene sets and pathways. The genes and pathways associated with ETI did not overlap with those whose expression changed with time only. PDIOs with a high FIS response did not significantly differ in any interpretable gene from the FIS-low organoids. The changes in the PDIOs gene expression upon the exposure to ETI cannot explain differences in the magnitude of PDIOs FIS-measured response to ETI. In conclusion, on incubation with ETI, genes of the CFTR-related pathways do not change their transcriptional activity; instead, overexpression was observed in genes of inflammatory-like cytokine response and receptor activation pathways.

OBJECTIVES: To evaluate the effect of short-term inhalational exposure to nanoparticles released during dental composite grinding on oxidative stress and antioxidant capacity markers. MATERIALS AND METHODS: Twenty-four healthy volunteers were examined before and after exposure in dental workshop. They spent 76.8 ± 0.7 min in the testing room during grinding of dental nanocomposites. The individual exposure to aerosol particles in each participant ́s breathing zones was monitored using a personal nanoparticle sampler (PENS). Exhaled breath condensate (EBC), blood, and urine samples were collected pre- and post-exposure to measure one oxidative stress marker, i.e., thiobarbituric acid reactive substances (TBARS), and two biomarkers of antioxidant capacity, i.e., ferric-reducing antioxidant power (FRAP) and reduced glutathione (GSH) by spectrophotometry. Spirometry and fractional exhaled nitric oxide (FeNO) were used to evaluate the effect of acute inhalational exposure. RESULTS: Mean mass of dental nanocomposite ground away was 0.88 ± 0.32 g. Average individual doses of respirable particles and nanoparticles measured by PENS were 380 ± 150 and 3.3 ± 1.3 μg, respectively. No significant increase of the post-exposure oxidative stress marker TBARS in EBC and plasma was seen. No decrease in antioxidant capacity biomarkers FRAP and GSH in EBC post-exposure was seen, either. Post-exposure, conjunctival hyperemia was seen in 62.5% volunteers; however, no impairment in spirometry or FeNO results was observed. No correlation of any biomarker measured with individual exposure was found, however, several correlations with interfering factors (age, body mass index, hypertension, dyslipidemia, and environmental pollution parameters) were seen. CONCLUSIONS: This study, using oxidative stress biomarker and antioxidant capacity biomarkers in biological fluids of volunteers during the grinding of dental nanocomposites did not prove a negative effect of this intense short-term exposure. However, further studies are needed to evaluate oxidative stress in long-term exposure of both stomatologists and patients and diverse populations with varying health statuses.

Obezita je chronické, relabující a progredující onemocnění s rostoucí prevalencí, které významně ovlivňuje zdraví a kvalitu života i u dětí. Je spojena se zvýšeným rizikem metabolických a kardiovaskulárních onemocnění, jako je inzulinová rezistence, diabetes mellitus 2. typu, hypertenze, dyslipidémie a metabolicky asociovaná steatóza jater. Obezita dále může vést k rozvoji syndromu spánkové apnoe, ortopedickým a psychickým komplikacím. Základem terapie je edukace zdravého životního stylu celé rodiny, která však často naráží na překážky, jako jsou časová náročnost, omezená dostupnost specialistů a nízká dlouhodobá adherence rodin. Telemedicína nabízí inovativní přístup ke zlepšení léčby obezity dětí prostřednictvím digitálních nástrojů, online konzultací, chytrých aplikací a nositelných technologií. Umožňuje efektivnější monitorování stravovacích a pohybových návyků, podporu psychického zdraví i snížení časové a finanční zátěže pro rodiny. Výsledky studií ukazují, že kombinace prezenční a distanční podpory a aktivní zapojení rodinných příslušníků vede k vyšší úspěšnosti v redukci tělesné hmotnosti a udržení zdravého životního stylu. Článek se zaměřuje na využití telemedicíny v léčbě obezity u dětí, přehled metod, které byly v této oblasti aplikovány, a jejich účinnost v kontextu současných vědeckých poznatků.
Obesity is a chronic, relapsing, and progressive disease with increasing prevalence, that significantly impacts health and quality of life, even in children. It is associated with an increased risk of metabolic and cardiovascular diseases such as insulin resistance, type 2 diabetes mellitus, hypertension, dyslipidemia, and metabolic dysfunction-associated steatotic liver disease. Additionally, obesity can lead to the development of sleep apnea syndrome, orthopedic issues, and psychological complications. The cornerstone of the care is educating the whole family about a healthy lifestyle; however, this may often be challenging due to obstacles such as time constraints, limited access to specialists, and low long-term adherence of families. Telemedicine offers an innovative approach to improving obesity treatment in children through digital tools, online consultations, smart applications, and wearable technologies. It enables more effective monitoring of dietary and physical activity habits, supports mental health, and reduces time and financial burdens for families. Studies indicate that combining in-person and remote support, along with active involvement of family members, leads to higher success rates in weight reduction and a healthy lifestyle maintenance. This article focuses on the use of telemedicine in the treatment of obesity in children, providing an overview of the methods applied in this field and their effectiveness in the context of current scientific knowledge.

Cíl: Cílem longitudinální studie bude zjistit rozdíly v 24hodinovém pohybovém chování (24hMB) (tj. spánku, sedavém chování (SB) a pohybové aktivitě (PA)) u českých dětí po jejich přestupu z mateřské do základní školy (ZŠ) (resp. z první/druhé třídy ZŠ do vyšších ročníků ZŠ) s ohledem na socioekonomické zázemí rodin, výskyt nadměrné tělesné hmotnosti účastníků či účasti v organizované PA. Metodika: 24hMB bude monitorováno po dobu 7 dnů pomocí akcelerometrů ActiGraph u rodin z městských a venkovských obcí z regionů Čech, Moravy a Slezska, jejichž členové dokončili první etapu výzkumu v období března 2022 až května 2023. Celkem 260 rodin, které dokončily první etapu výzkumu, poskytlo v rodinném deníku kontaktní údaje a nevyloučilo možnost pokračovat ve výzkumu ve druhé etapě v roce 2025/2026. Rodinný deník bude kromě informací o každodenním času uléhání/vstávání, době trávené před obrazovkou/monitorem/displejem obsahovat i informace o účasti v organizované PA, antropometrická data a údaje o rodinném zázemí. Výsledky: Z první etapy výzkumu vyplynulo, že celkem 25,9 % dívek a 26,7 % chlapců splnilo všechna tři doporučení ke spánku, PA a SB současně a dalších 44,7 % dívek a 46,1 % chlapců dosáhlo alespoň kombinaci dvou z těchto tří doporučení, bez rozdílů mezi pohlavím, věkovou kategorií nebo úrovní tělesné hmotnosti dětí. Nadměrná tělesná hmotnost matek významně (p < 0,05) snížila šanci dětí dosáhnout alespoň dvou ze tří doporučení, zatímco vysokoškolské vzdělání rodičů a dodržování alespoň dvou ze tří doporučení matkami významně (p < 0,05) zvýšilo pravděpodobnost, že také děti doporučení dodrží. Účast dětí v organizované PA významně (p < 0,05) zvyšuje jejich šanci na dosažení alespoň dvou ze tří doporučení k 24hMB. Závěry: První etapa longitudinálního výzkumu poukázala na stěžejní rodinné faktory (úroveň vzdělání rodičů, matčina úroveň tělesné hmotnosti a míra dosažení doporučení k 24hMB, podpora aktivní účasti dětí v organizované PA) zvyšující šanci dětí ke splnění zdravotních doporučení pro 24hMB.
Objective: The aim of this longitudinal study will be to investigate the differences in 24-hour movement behaviour (24hMB) (i.e., sleep, sedentary behaviour (SB) and physical activity (PA)) in Czech children after their transition from kindergarten to primary school (or from first/second grade to upper grades of primary school) with respect to the socioeconomic background of families, the prevalence of overweight participants or participation in organised PA. Methods: 24hMB will be monitored for seven days using ActiGraph accelerometers in families from urban and rural areas in the Bohemia, Moravia and Silesia regions, whose members completed the first phase of the study between March 2022 and May 2023. The 260 families who finished the first phase of the research provided their contact details in the family diary and have not ruled out the possibility of participating in the second phase in 2025/2026. The family diary will include information on daily bedtime and wake-up times, screen time, and participation in organised PA, as well as anthropometric data and family background information. Results: The findings from the first phase of the research showed that a total of 25.9% of girls and 26.7% of boys met all three guidelines on sleep, PA and SB simultaneously, and 44.7% of girls and 46.1% of boys achieved at least a combination of two of the three guidelines. No differences were observed between gender, age, or body weight levels of the children. Maternal excess body weight significantly (p < 0.05) decreased the odds of children achieving at least two of the three guidelines, whereas parental higher education and maternal adherence to at least two of the three guidelines significantly (p < 0.05) increased the odds that children also complied with the guidelines. Children’s participation in organised PA significantly (p < 0.05) increased their chances of achieving at least two of the three 24hMB guidelines. Conclusions: The first phase of the longitudinal research highlighted key family factors (parental education level, mother’s body weight, adherence to 24hMB guidelines, and support for children’s active participation in organised PA) that increase children’s chances of meeting guidelines for 24hMB.

OBJECTIVE: The aim of the study was the assessment of adherence to antiretroviral (ARV) treatment in a population of people living with HIV (PWH), improving the awareness of PWH, drawing attention to the risk of developing HIV drug resistance and subsequent treatment failure. METHODS: The basic cohort consisted of PWH followed up long-term at the HIV centre of the University Hospital Pilsen. Adherence to treatment was assessed by ARV levels. Nucleoside analogs were determined in urine by high pressure liquid chromatography (HPLC), in relation to clinical data, viral load (HIV RNA), and absolute CD4 and CD8 T cell counts. To assess mental and physical state of the patients, a modified SF-36 questionnaire was used to measure social relationships, education and ability to relax. RESULTS: From a group of 131 PWH, 18 (13.7%) with zero levels and 113 (86.3%) with any detectable ARV levels were followed for 6-12 months. A statistically significant lower viral load was demonstrated in patients who adhered to the treatment at the time of the test as indicated by ARV levels in the urine. CD4 T lymphocyte values in adherent patients were, as expected, statistically significantly higher. A significant difference for CD8 T lymphocyte was not demonstrated. A survey assessed subjective factors influencing the degree of adherence. PWH consider important: quality care enabling trust, low risk of developing opportunistic infections, self-sufficiency, quality of sleep, managing leisure activities, and good family relationships. Quality of life evaluation and satisfaction in the monitored areas were similar in both groups of PWH. CONCLUSIONS: Non-adherence leads to deterioration of CD4 and viral load levels and may be the cause of the development of HIV drug resistance and treatment failure on the part of the patient. PWH with zero or low urinary nucleoside levels were repeatedly instructed about the need for regular and sustained medication use. Regular checks with a laboratory examination service are needed to detect early emergence of resistance and side effects of the treatment, which are initially only detectable in the laboratory.

BACKGROUND AND OBJECTIVE: In prostate cancer treated with androgen deprivation therapy (ADT), the initial sign of treatment resistance is often prostate-specific antigen (PSA) progression, followed by radiographic progression. However, the association between these two forms of progression remains unclear, especially in patients with metastatic castration-sensitive prostate cancer (mCSPC) treated with androgen receptor pathway inhibitors. We sought to evaluate the association between radiographic progression, PSA progression, and outcomes of apalutamide therapy in mCSPC. METHODS: We analyzed individual participant-level data for patients randomized within the TITAN trial who experienced radiographic progression during follow-up (N = 326). This study investigated radiographic progression without simultaneous or preceding PSA progression, as defined by the Prostate Cancer Working Group 2 (discordant progression), and explored the association of such progression with radiographic progression-free survival. KEY FINDINGS AND LIMITATIONS: Among the patients who developed radiographic progression, 115 (35.3%) had been treated with apalutamide plus ADT (the apalutamide group) and 211 (64.7%) with placebo plus ADT (the placebo group). Discordant progression occurred in 52.2% of patients (60 of 115) in the apalutamide group and 27.5% (58 of 211) in the placebo group (p < 0.001). A multivariable logistic regression analysis showed that discordant progression was associated with apalutamide treatment. We found evidence of an association between discordant progression and shorter radiographic progression-free survival. CONCLUSIONS AND CLINICAL IMPLICATIONS: This study found that nearly half of the patients with mCSPC treated with apalutamide who experienced radiographic progression developed it without corresponding PSA progression, suggesting that heavy reliance on PSA monitoring may be inadequate for assessing disease activity in this context. PATIENT SUMMARY: In patients who have metastatic castration-sensitive prostate cancer (mCSPC) and are being treated with apalutamide, radiographic images may show cancer progression even if prostate-specific antigen tests indicate no change. This highlights the importance of regular imaging when using apalutamide to manage mCSPC.

Colorectal cancer (CRC) ranks as the second most prevalent malignancy globally, highlighting the urgent need for more effective diagnostic and therapeutic strategies, as well as a deeper understanding of its molecular basis. Extensive research has demonstrated that cells actively secrete extracellular vesicles (EVs) to mediate intercellular communication at both proximal and distal sites. In this study, we conducted a comprehensive analysis of the RNA content of small extracellular vesicles (sEVs) secreted into the culture media of five frequently utilised CRC cell lines (RKO, HCT116, HCT15, HT29, and DLD1). RNA sequencing data revealed significant insights into the RNA profiles of these sEVs, identifying nine protein-coding genes and fourteen long non-coding RNA (lncRNA) genes that consistently ranked among the top 30 most abundant across all cell lines. Notably, the genes found in sEVs were highly similar among the cell lines, indicating a conserved molecular signature. Several of these genes have been previously documented in the context of cancer biology, while others represent novel discoveries. These findings provide valuable insights into the molecular cargo of sEVs in CRC, potentially unveiling novel biomarkers and therapeutic targets.
