Penile squamous cell carcinoma (pSCC) represents an uncommon malignancy characterized by stagnant mortality, psychosexual distress, and a highly variable prognosis. Currently, the World Health Organization distinguishes between human papillomavirus (HPV)-related and HPV-independent pSCC. Recently, there has been an evolving line of research documenting the enrichment of HPV-independent pSCC with a high tumor mutational burden (TMB) and programmed death ligand-1 expression, as well as clusters of genes associated with HPV status. In this study, we conducted comprehensive next-generation sequencing DNA profiling of 146 pSCC samples using a panel consisting of 355 genes associated with tumors. This profiling was correlated with immunohistochemical markers and prognostic clinical data. A survival analysis of recurrent genomic events (found in ≥10 cases) was performed. TP53, CDKN2A, ATM, EPHA7, POT1, CHEK1, GRIN2A, and EGFR alterations were associated with significantly shortened overall survival in univariate and multivariate analysis. HPV positivity, diagnosed through both p16 immunohistochemistry and HPV DNA analysis, displayed no impact on survival but was associated with high-grade, lymphatic invasion, programmed death ligand-1 negativity/weak expression, and low TMB. FAT1, TP53, CDKN2A, CASP8, and HRAS were more often mutated in HPV-independent pSCC. In contrast, HPV-associated pSCCs were enriched by EPHA7, ATM, GRIN2A, and CHEK1 mutations. PIK3CA, FAT1, FBXW7, and KMT2D mutations were associated with high TMB. NOTCH1, TP53, CDKN2A, POT1, KMT2D, ATM, CHEK1, EPHA3, and EGFR alterations were related to adverse clinicopathologic signs, such as advanced stage, high tumor budding, and lymphovascular invasion. We detected 160 alterations with potential treatment implications, with 21.2% of samples showing alterations in the homologous recombination repair pathway. To the best of our knowledge, this study describes the largest cohort of pSCC with complex molecular pathologic, clinical, and prognostic analysis correlating with prognosis.

PURPOSE: TACE induces variable systemic effects by producing factors that promote inflammation, oncogenesis, and angiogenesis. Here we compare concentrations of microRNAs (miR-21, miR-210 and miR-34a) and vascular endothelial growth factor (VEGF) in hepatocellular carcinoma (HCC) patients undergoing TACE with degradable (DSM) and nondegradable (DEB) particles and potential use of these biomarker changes for prediction of patient outcomes. MATERIALS AND METHODS: Overall, 52 patients with HCC treated with DSM TACE (24 patients) and DEB TACE (28 patients) were included in this prospective study. Concentrations of studied biomarkers were measured from blood plasma preprocedurally, immediately (< 90 min) postprocedurally, and 24-h after TACE. Levels were compared between DSM and DEB TACE and correlated with treatment response six and 12 months after the first TACE. RESULTS: Both DSM and DEB TACE elevated plasma levels of miR-21, miR-34a, and miR-210 at 24 h post-procedure compared to baseline levels (FC 1.25-4.0). MiR-34a elevation immediately after TACE was significantly associated with nonprogressive disease compared to those with progressive disease at both six months (FCa: p = 0.014) and 12 months (FCa: p = 0.029) post-TACE. No significant biomarker changes were found between the embolization particle groups. However, VEGF levels showed a decrease only in the DSM TACE group (FC24: p = < 0.001). CONCLUSION: Embolization particle type did not significantly impact miRNA or VEGF changes post-TACE. However, miR-34a elevation immediately after the procedure predicts better patient outcome and may prove useful as a biomarkers for the monitoring of clinical outcomes. LEVEL OF EVIDENCE: Level 3 Prospective cohort study.

OBJECTIVE: Research suggests that disrupted interoception contributes to the development and maintenance of functional neurological disorder (FND); however, no functional neuroimaging studies have examined the processing of interoceptive signals in patients with FND. METHODS: The authors examined univariate and multivariate functional MRI neural responses of 38 patients with mixed FND and 38 healthy control individuals (HCs) during a task exploring goal-directed attention to cardiac interoception-versus-control (exteroception or rest) conditions. The relationships between interoception-related neural responses, heartbeat-counting accuracy, and interoceptive trait prediction error (ITPE) were also investigated for FND patients. RESULTS: When attention was directed to heartbeat signals versus exteroception or rest tasks, FND patients showed decreased neural activations (and reduced coactivations) in the right anterior insula and bilateral dorsal anterior cingulate cortices (among other areas), compared with HCs. For FND patients, heartbeat-counting accuracy was positively correlated with right anterior insula and ventromedial prefrontal activations during interoception versus rest. Cardiac interoceptive accuracy was also correlated with bilateral dorsal anterior cingulate activations in the interoception-versus-exteroception contrast, and neural activations were correlated with ITPE scores, showing inverse relationships to those observed for heartbeat-counting accuracy. CONCLUSIONS: This study identified state and trait interoceptive disruptions in FND patients. Convergent between- and within-group findings contextualize the pathophysiological role of cingulo-insular (salience network) areas across the spectrum of functional seizures and functional movement disorder. These findings provide a starting point for the future development of comprehensive neurophysiological assessments of interoception for FND patients, features that also warrant research as potential prognostic and monitoring biomarkers.

Necrotizing enterocolitis (NEC) is one of the most devastating intestinal diseases observed in preterm in the first days of life. Researchers have recently focused on potential predictive biomarkers for early and concomitant diagnoses. Thus, we inquired about the linkage of intestinal dysbiosis, one of the most important factors in NEC development to the gut microbiota. In this study, the systematic differences in the bacterial composition between neonates affected by NEC and healthy newborns were highlighted by metagenomic analysis. The next-generation sequencing of the V3-V4 variable region of the 16S rRNA gene and gene-specific qPCR analyzed the untargeted gut microbiota. Total bacteria, total and fecal coliform loads in stool samples with NEC were higher than control. OTU-level relative abundances of NEC infant was characterized by Firmicutes and Bacteroidetes at phylum levels. At the genus level, NEC stool was identified by the lack of Klebsiella and the presence of Roseburia, Blautia, and Parasutterella. Finally, Clostridium fessum was the predominant species of Clostridium genus in disease and healthy specimens at the species level, whereas Clostridium jeddahitimonense was at NEC diagnosis. Despite a strong relationship between pathophysiology and characterization of gut microbiota at a clinical diagnosis of NEC, our results emphasize the broad difficulty in identifying potential biomarkers.

BACKGROUND & AIMS: Homozygous Pi∗Z mutation in alpha-1 antitrypsin (Pi∗ZZ genotype) predisposes to pulmonary loss-of-function and hepatic gain-of-function injury. To facilitate selection into clinical trials typically targeting only 1 organ, we systematically evaluated an international, multicenter, longitudinal, Pi∗ZZ cohort to uncover natural disease course and surrogates for future liver- and lung-related endpoints. METHODS: Cohort 1 recruited 737 Pi∗ZZ individuals from 25 different centers without known liver comorbidities who received a baseline clinical and laboratory assessment as well as liver stiffness measurement (LSM). A follow-up interview was performed after at least 6 months. Cohort 2 consisted of 135 Pi∗ZZ subjects without significant liver fibrosis, who received a standardized baseline and follow-up examination at least 2 years later, both including LSM. RESULTS: During 2634 patient-years of follow-up, 39 individuals died, with liver and lung being responsible for 46% and 36% of deaths, respectively. Forty-one Pi∗ZZ subjects who developed a hepatic endpoint presented with significantly higher baseline liver fibrosis surrogates, that is, LSM (24 vs 5 kPa, P < .001) and aspartate aminotransferase-to-platelet ratio index (1.1 vs 0.3 units, P < .001). Liver-related endpoints within 5 years were most accurately predicted by LSM (area under the curve 0.95) followed by aspartate aminotransferase-to-platelet ratio index (0.92). Baseline lung parameters displayed only a moderate predictive utility for lung-related endpoints within 5 years (forced expiratory volume in the first second area under the curve 0.76). Fibrosis progression in those with no/mild fibrosis at baseline was rare and primarily seen in those with preexisting risk factors. CONCLUSIONS: Noninvasive liver fibrosis surrogates accurately stratify liver-related risks in Pi∗ZZ individuals. Our findings have direct implications for routine care and future clinical trials of Pi∗ZZ patients.

PURPOSE OF REVIEW: This review explores the design and endpoints of perioperative platforms in clinical trials for muscle-invasive bladder cancer (MIBC). RECENT FINDINGS: The choice of clinical trial design in perioperative platforms for MIBC must align with specific research objectives to ensure robust and meaningful outcomes. Novel designs in perioperative platforms for MIBC integrate bladder-sparing approaches. Primary endpoints such as pathological complete response and disease-free survival are highlighted for their role in expediting trial results in perioperative setting. Incorporating patient-reported outcomes is important to inform healthcare decision makers about the outcomes most meaningful to patients. Given the growing body of evidence, potential biomarkers, predictive and prognostic tools should be considered and implemented when designing trials in perioperative platforms for MIBC. SUMMARY: Effective perioperative platforms for MIBC trials are critical in enhancing patient outcomes. The careful selection and standardization of study designs and endpoints in the perioperative platform are essential for the successful implementation of new therapies and the advancement of personalized treatment approaches in MIBC.

Clear-cell renal cell carcinoma (ccRCC) is a common urological malignancy with an increasing incidence. The development of molecular biomarkers that can predict the response to treatment and guide personalized therapy selection would substantially improve patient outcomes. Dysregulation of non-coding RNA (ncRNA) has been shown to have a role in the pathogenesis of ccRCC. Thus, an increasing number of studies are being carried out with a focus on the identification of ncRNA biomarkers in ccRCC tissue samples and the connection of these markers with patients' prognosis, pathological stage and grade (including metastatic potential), and therapy outcome. RNA sequencing analysis led to the identification of several ncRNA biomarkers that are dysregulated in ccRCC and might have a role in ccRCC development. These ncRNAs have the potential to be prognostic and predictive biomarkers for ccRCC, with prospective applications in personalized treatment selection. Research on ncRNA biomarkers in ccRCC is advancing, but clinical implementation remains preliminary owing to challenges in validation, standardization and reproducibility. Comprehensive studies and integration of ncRNAs into clinical trials are essential to accelerate the clinical use of these biomarkers.

Cíl: Naším cílem bylo zhodnotit využitelnost hladiny kisspeptinu (KP) v séru, měřeného v I. trimestru (11–14 týdnu), jako nového biomarkeru, který může predikovat prenatální komplikace. Materiály a metody: Prospektivní případová kontrolní studie prospektivně shromážděných dat. Vzorky krve všech pacientek (n = 124) byly uchovány při –70 °C pro stanovení hladin KP-10 a KP-54 v séru. Byly stanoveny a srovnány hladiny KP u žen, u kterých došlo ke komplikacím vč. retardace růstu plodu (FGR – fetal growth retardation), těhotenstvím indukované hypertenze (PIH – pregnancy-induced hypertension), předčasného porodu, gestačního diabetu a úmrtí plodu. Kontrolní skupinu tvořily odpovídající subjekty, které dokončily těhotenství bez problémů. Byl zkoumán prediktivní účinek hladiny KP v séru na nepříznivé výsledky těhotenství. Výsledky: Mezi všemi pacientkami s nepříznivými výsledky těhotenství byla hladina KP-10 významně vyšší u těch, u kterých došlo k FGR (p = 0,025). V kohortě pacientek postižených těhotenstvím indukovanou hypertenzí (PIH), buď samotnou nebo doprovázenou preeklampsií, byla zaznamenána tendence k vyšším hladinám KP-10 (p = 0,059), ačkoli nebylo dosaženo statistické významnosti. Nicméně pokud jde o KP-10, vypočtená cutoff hodnota a plocha pod křivkou (AUC – area under the curve) pro predikci nástupu FGR byly statisticky významné (AUC: 0,684; p = 0,006). Bylo zjištěno, že model vytvořený s KP-10, PIH a plazmatickým proteinem A spojeným s těhotenstvím (PAPP-A) je významný při predikci vývoje FGR (p = 0,006; NPV: 98 %; PPV: 21,4 %; OR: 0,10; 95% CI 0,016–0,611). Závěry: Hladiny KP v séru matky v I. trimestru mohou být využity jako biomarker v I. trimestru, který může predikovat vývoj FGR.
Objective: We aimed to evaluate the usefulness of serum kisspeptin (KP), measured in the 1st trimester (11–14 weeks), as a new biomarker that can predict antenatal complications. Materials and methods: A prospective case-control study of prospectively collected data. Blood samples of all patients (N = 124) were preserved at –70 °C for the assessment of serum KP-10 and KP-54 levels. The KP levels were analyzed for comparison among women who experienced complications including fetal growth retardation (FGR), pregnancy-induced hypertension (PIH), preterm delivery, gestational diabetes, and fetal death. The control group consisted of matching subjects who completed their pregnancies without problems. The predictive effect of serum KP on adverse pregnancy outcomes was investigated. Results: Among all adverse pregnancy outcomes, the KP-10 level was significantly higher in patients who developed FGR (P = 0.025). In the patient cohort affected by PIH, either accompanied by preeclampsia or standalone, there was a trend towards higher KP-10 levels (P = 0.059), although statistical significance was not achieved. However, regarding KP-10, the calculated cut-off value and the area under the curve (AUC) for predicting the onset of FGR were statistically significant (AUC: 0.684; P = 0.006). The model established with KP-10, PIH, and pregnancy associated plasma protein-A (PAPP-A) was found to be significant in predicting the development of FGR (P = 0.006; NPV: 98%; PPV: 21.4%; OR: 0.10; 95% CI 0.016–0.611). Conclusions: First trimester maternal serum KP levels may have the potential to be used as a 1st trimester biomarker that can predict the development of FGR.
Alzheimerova choroba je nejčastější příčinou demence a včasná diagnostika je klíčová pro zahájení léčby. Porucha čichu, zejména schopnost identifikace pachů, byla opakovaně identifikována jako raný příznak neurodegenerativních změn a může pomoci při časné detekci Alzheimerovy choroby. Psychofyzické testy čichu, jako je Sniffin’ Sticks, (SST) University of Pennsylvania Smell Identification Test (UPSIT), či test parfémovaných fixů (OMT), jsou spolehlivými nástroji pro hodnocení čichových funkcí a mají potenciál doplnit tradiční neuropsychologické testy. Kombinace čichových a kognitivních testů významně zvyšuje přesnost predikce nástupu demence.
Koutná V, Štěpánek L, Trajerová R, Janout V, Janoutová J. Olfactory impairment as a biomarker in early diagnosis of Alzheimer’s disease in primary care Alzheimer’s disease is the most common cause of dementia and early diagnosis is key to initiating treatment. Olfactory dysfunction, particularly the ability to discriminate odors, has been repeatedly identified as an early sign of neurodegenerative changes and may aid in the early detection of Alzheimer’s disease. Psychophysical olfactory tests such as the Sniffin’ Sticks (SST), University of Pennsylvania Smell Identification Test (UPSIT) or the Odorized Marker Test (OMT) are reliable tools for assessing olfactory function and have potential to complement traditional neuropsychological tests. The combination of olfactory and cognitive tests significantly increases the accuracy of predicting the onset of dementia.
Malobuněčný karcinom plic (small cell lung cancer, SCLC) představuje agresivní malignitu s omezenými pokroky v léčbě včetně nenaplněné potřeby u pacientů s limitovaným stadiem onemocnění (limited stage SCLC, LS SCLC). Standardní terapie zahrnuje konkomitantní chemoradioterapii následovanou profylaktickým ozařováním mozkovny u vhodných pacientů. Přestože konkomitantní chemoradioterapie prokazatelně zlepšuje celkové přežití, míra recidivy zůstává vysoká a dlouhodobá prognóza je nepříznivá. Nové perspektivní přístupy, které mají za cíl prodloužení přežití a snížení rizika relapsu, zahrnují především imunoterapii. Studie fáze III ADRIATIC hodnotila účinnost durvalumabu u pacientů bez progrese po chemoradioterapii. Analýza ukázala, že podání durvalumabu významně prodlužuje celkové přežití a přežití bez progrese onemocnění. Výsledky naznačují, že udržovací imunoterapie by se mohla stát novým standardem léčby LS SCLC. Další výzkumy jsou zaměřeny na optimalizaci dávkování radioterapie, kombinaci léčiv a identifikaci biomarkerů predikujících odpověď na imunoterapii.
Smaii cell lung cancer (SCLC) is an aggressive malignancy with limited treatment advances, including unmet need in patients with limited stage disease (LS SCLC). Standard therapy includes concomitant chemoradiotherapy followed by prophylactic cranial irradiation in appropriate patients. Although concomitant chemoradiotherapy has been shown to improve overall survival, recurrence rates remain high and long-term prognosis unfavorable. New promising approaches to prolong survival and reduce the risk of relapse include immunotherapy in particular. The phase III ADRIATIC trial evaluated the efficacy of durvalumab in patients without progression after chemoradiotherapy. The analysis showed that administration of durvalumab significantly prolonged overall and progression free survival. The results suggest that maintenance immunotherapy could become the new standard of care for LS SCLC. Further research is focused on optimizing radiotherapy dosing, drug combinations, and identifying biomarkers predictive of response to immunotherapy.
