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.

BACKGROUND: This study aimed to assess the mid-term effects of focused extracorporeal shockwave therapy (ESWT) on clinical symptoms and tendon structure in patellar tendinopathy. Ultrasound (US) evaluation and an innovative in vivo analysis of intra-tendinous morphology using validated spatial frequency analysis (SFA) software were employed to quantify the organization and density of collagen fascicles. METHODS: This prospective cohort study included 21 recreational athletes (mean age 29.9 ± 9.3 years) with chronic unilateral symptomatic patellar tendinopathy. ESWT was applied as monotherapy over four weekly sessions. Pain was assessed using the Numeric Rating Scale (NRS) and disease severity with the Victorian Institute of Sports Assessment - Patella (VISA-P) questionnaire. Morphological parameters, such as tendon diameter (TD), were assessed with US and analyzed using SFA software. The asymptomatic tendons served as controls. Follow-up assessments were conducted at the end of the treatment period and 3 months posttreatment. RESULTS: Baseline evaluations revealed increased TD in proximal part of the tendon ( P = 0.001) and decreased organization of collagen fascicles ( P = 0.013) in symptomatic tendons compared to asymptomatic controls. At the 3-month follow-up, symptomatic tendons showed significant reductions in TD ( P < 0.001) and improvements in both organization and density of collagen fascicles throughout various parameters - peak spatial frequency radius (PSFR) ( P = 0.024), P6 ( P = 0.05), Q6 ( P = 0.016), PPP ( P = 0.003). No significant morphological changes were observed in asymptomatic tendons. Clinical evaluations demonstrated significant reductions in NRS ( P < 0.001) and increases in Victorian Institute of Sports Assessment - Patella (VISA-P) scores ( P < 0.001) at all time points. CONCLUSION: The study suggests that ESWT may have the potential to induce positive structural changes in patellar tendinopathy, including improved organization and density of collagen fascicles. These findings indicate that ESWT could be a promising noninvasive approach to managing patellar tendinopathy, with observed improvements in clinical symptoms and tendon structure. However, further high-quality research is needed to confirm these results and establish their long-term efficacy.

Už niekoľko desaťročí podiel seniorov v populácii vyspelých krajín rastie, a to aj pre predlžovanie života. To má byť spojené s napĺňaním jedného zo základných princípov geriatrie – s „pridávaním života rokom“, t. j. so zlepšovaním kvality života. Tá je medzi ľuďmi i v odbornej komunite hodnotená rôzne, multidimenzionálne. U nemalej časti starších ľudí pozorujeme stúpajúcu tendenciu akejsi „estetickej komponenty“ vnímania kvality vlastného života – aj seniori stále častejšie dbajú na svoj estetický vzhľad. V tzv. západnom svete je tento trend dokumentovaný dlhšie, v ostatných rokoch ho pozorujeme už aj na Slovensku. Moderná medicína ponúka viacero prístupov, ako naplniť očakávania seniorov, ktorí chcú zlepšiť vlastný pocit zo svojho vzhľadu. Z medicínskeho hľadiska budeme u seniorov aj v tomto prípade preferovať neinvazívne alebo miniinvazívne metódy. Predkladaná práca sa zaoberá možnosťami a obmedzeniami niektorých bežne dostupných minimálne invazívnych „antiageingových“ procedúr u starších ľudí.

For several decades, there has been an increase in the proportion of seniors in developed countries, one of the reasons of which is the prolongation of life expectancy. In accordance with one of the basic principles of geriatrics, it should be one’s aim to „add life to years“, meaning improving the quality of life of the elderly. Quality of life is evaluated differently among people and in the scientific community – it is multi-dimensional. Among a considerable number of elderly people, we observe a rising tendency of an „aesthetic component“ in the perception of the quality of their life – even seniors pay more attention to their aesthetic appearance. In the so-called Western world this trend has been observed for a long time, and in recent years so have we in Slovakia. Modern medicine offers several approaches to meet the expectations of seniors who want to improve perception of their appearance. From a medical point of view, we will prefer noninvasive or mini invasive methods for seniors. The presented work deals with the possibilities and limitations of some commonly available minimally invasive „anti-ageing“ procedures for seniors.

BACKGROUND AND OBJECTIVE: The European Association of Urology urolithiasis guidelines provide evidence-based recommendations for the diagnosis and treatment of urinary stone disease. Given the complexity and variability of stone formation, individualised patient management is emphasised. METHODS: The guidelines incorporate evidence from the latest research and focus on risk assessment, imaging techniques, pharmacological management, and surgical interventions. A research librarian conducted literature searches for urolithiasis in the Cochrane Library, Medline, and Embase databases via Dialog-Datastar. The strength of recommendations is also rated. KEY FINDINGS AND LIMITATIONS: Diagnosis relies on a combination of clinical history, biochemical evaluation, and imaging, with ultrasound as the first-line modality and low-dose computed tomography as the gold standard for precise stone assessment. Stone composition and burden influence treatment decisions with algorithms primarily based on stone size, location, and composition. Nonsteroidal anti-inflammatory drugs are recommended for first-line pain management, with opioids reserved as a secondary option. Medical expulsive therapy with α-blockers may be considered for selected patients with ureteral stones. Extracorporeal shockwave lithotripsy, ureteroscopy, and percutaneous nephrolithotomy remain the primary intervention modalities, with selection based on stone characteristics and patient factors. Advances in multiplanar imaging have improved assessment of the stone burden, although further research is needed to refine predictive models. Genetic testing is recommended for high-risk patients to guide personalised treatment. CONCLUSIONS AND CLINICAL IMPLICATIONS: The guidelines provide a framework for clinical decision-making while acknowledging the need for continued advances in urolithiasis.

BACKGROUND: Temporal interference stimulation (TIS) is a novel noninvasive electrical stimulation technique to focally modulate deep brain regions; a minimum of two high-frequency signals (f1 and f2 > 1 kHz) interfere to create an envelope-modulated signal at a deep brain target with the frequency of modulation equal to the difference frequency: Δf = |f2 - f1|. OBJECTIVE: The goals of this study were to verify the capability of TIS to modulate the subthalamic nucleus (STN) with Δf and to compare the effect of TIS and conventional deep brain stimulation (DBS) on the STN beta oscillations in patients with Parkinson's disease (PD). METHODS: DBS leads remained externalized after implantation, allowing local field potentials (LFPs) recordings in eight patients with PD. TIS was performed initially by two pairs (f1 = 9.00 kHz; f2 = 9.13 kHz, 4 mA peak-peak per pair maximum) of scalp electrodes placed in temporoparietal regions to focus the envelope signal maximum (Δf = 130 Hz) at the motor part of the STN target. RESULTS: The comparison between the baseline LFPs and recordings after TIS and conventional DBS sessions showed substantial suppression of high beta power peak after both types of stimulation in all patients. CONCLUSIONS: TIS has the potential to effectively modulate the STN and reduce the beta oscillatory activity in a completely noninvasive manner, as is traditionally possible only with intracranial DBS. Future studies should confirm the clinical effectiveness of TIS and determine whether TIS could be used to identify optimal DBS candidates and individualize DBS targets. © 2025 The Author(s).

BACKGROUND AND PURPOSE: Diffuse gliomas, a heterogeneous group of primary brain tumors, have traditionally been stratified by histology, but recent insights into their molecular features, especially the IDH mutation status, have fundamentally changed their classification and prognosis. Current diagnostic methods, still predominantly relying on invasive biopsy, necessitate the exploration of noninvasive imaging alternatives for glioma characterization. MATERIALS AND METHODS: In this prospective study, we investigated the utility of the spherical mean technique (SMT) in predicting the IDH status and histologic grade of adult-type diffuse gliomas. Patients with histologically confirmed adult-type diffuse glioma underwent a multiparametric MRI examination using a 3T system, which included a multishell diffusion sequence. Advanced diffusion parameters were obtained using SMT, diffusional kurtosis imaging, and ADC modeling. The diagnostic performance of studied parameters was evaluated by plotting receiver operating characteristic curves with associated area under curve, specificity, and sensitivity values. RESULTS: A total of 80 patients with a mean age of 48 (SD, 16) years were included in the study. SMT metrics, particularly microscopic fractional anisotropy (μFA), intraneurite voxel fraction, and μFA to the third power (μFA3), demonstrated strong diagnostic performance (all AUC = 0.905, 95% CI, 0.835-0.976; P < .001) in determining IDH status and compared favorably with diffusional kurtosis imaging and ADC models. These parameters also showed a strong predictive capability for tumor grade, with intraneurite voxel fraction and μFA achieving the highest diagnostic accuracy (AUC = 0.937, 95% CI, 0.880-0.993; P < .001). Control analyses on normal-appearing brain tissue confirmed the specificity of these metrics for tumor tissue. CONCLUSIONS: Our study highlights the potential of SMT for noninvasive characterization of adult-type diffuse gliomas, with a potential to predict IDH status and tumor grade more accurately than traditional ADC metrics. SMT offers a promising addition to the current diagnostic toolkit, enabling more precise preoperative assessments and contributing to personalized treatment planning.

BACKGROUND: Large vessel carotid stenosis is a significant cause of ischaemic stroke. Indications for surgical revascularisation depend on the severity of the stenosis and clinical symptoms. However, mild symptoms such as TIA (Transient ischaemic attack), amaurosis fugax or minor stroke precede large strokes in only 15% of cases. AIM: The aim of this prospective study is to evaluate whether retinal perfusion is impacted in significant carotid stenosis. Automated retinal oximetry will be used to better assess perfusion in the post-stenotic basin. We presume the more stenotic the blood vessel, the more reduced the retinal perfusion is, resulting in adaptive changes such as greater arteriovenous saturation difference due to greater oxygen extraction. This could broaden the indication spectrum for revascularisation for carotid stenosis. METHODS: We plan to enroll yearly 50 patients with significant carotid stenosis and cross-examine them with retinal oximetry. The study group will provide stenotic vessels and, non-stenotic vessels will form the control group. Patients with significant carotid stenosis will undergo an MRI (Magnetic Resonnance imaging) examination to determine the presence of asymptomatic recent ischaemic lesions in the stenotic basin, and the correlation to oximetry parameters. STATISTICS: The stenosis severity and retinal oximetry parameters will be compared for study and control groups with a threshold of 70%, respectively 80% and 90% stenosis. Results will be then reevaluated with emphasis on MRI findings in the carotid basin. CONCLUSION: This prospective case control study protocol will be used to launch a multicentre trial assessing the relationship between significant carotid stenosis and retinal perfusion measured with automated retinal oximetry. Despite these differences, the findings indicate the potential of retinal oximetry for noninvasive real-time measurements of oxyhaemoglobin saturation in central nervous system vessels. Following calibration upgrade and technological improvement, verification retinal oximetry may potentially be applied to critically ill and anaesthesia care patients. The study on combined scanning laser ophthalmoscope and retinal oximetry supports the feasibility of the technique for oximetry analysis in newly born babies.

Arterial compliance (AC) is an important cardiovascular parameter characterizing mechanical properties of arteries. AC is significantly influenced by arterial wall structure and vasomotion, and it markedly influences cardiac load. A new method, based on a two-element Windkessel model, has been recently proposed for estimating AC as the ratio of the time constant T of the diastolic blood pressure decay and peripheral vascular resistance derived from clinically available stroke volume measurements and selected peripheral blood pressure parameters which are less prone to peripheral distortions. The aim of this study was to validate AC estimation using a virtual population generated by in silico model of the systemic arterial tree. In the second part of study, we analysed causal coupling between AC oscillations and variability of its potential determinants - systolic blood pressure and heart rate in healthy young human subjects. The pool of virtual subjects (n=3818) represented an extensive AC distribution. AC was estimated from the peripheral blood pressure curve and by the standard method from the aortic blood pressure curve. The proposed method slightly overestimated AC set in the model but both ACs were strongly correlated (r=0.94, p<0.001). In real data, we observed that AC dynamics was coupled with basic cardiovascular parameters variability independently of the autonomic nervous system state. In silico analysis suggests that AC can be reliably estimated by noninvasive method. The analysis of short-term AC variability together with its determinants could improve our understanding of factors involved in AC dynamics potentially improving assessment of AC changes associated with atherosclerosis process. Key words Arterial compliance, Cardiovascular model, Arterial blood pressure, Causal analysis, Volume-clamp photoplethysmography.

BACKGROUND: Dexamethasone 6 mg in patients with severe COVID-19 has been shown to decrease mortality and morbidity. The effects of higher doses of corticosteroid, that would further increase anti-inflammatory effects, are uncertain. The objective of our study was to assess the effect of 20 mg dexamethasone vs. 6 mg dexamethasone intravenously in patients with moderate-to-severe acute respiratory distress syndrome (ARDS) and COVID-19. METHODS: In a multicenter, open-label, randomized trial conducted in nine hospitals in the Czech Republic, we randomized adult patients with ARDS and COVID-19 requiring high-flow oxygen, noninvasive or invasive mechanical ventilation to receive either intravenous high-dose dexamethasone (20 mg/day on days 1-5, 10 mg/day on days 6-10) or standard-dose dexamethasone (6 mg/d, days 1-10). The primary outcome was 28-day ventilator-free days. The five secondary outcomes were 60-day mortality, C-reactive protein dynamics, 14-day WHO (World Health Organization) Clinical Progression Scale score, adverse events and 90-day Barthel index. The long-term outcomes were 180- and 360-day mortality and the Barthel index. The planned sample size was 300, with interim analysis after enrollment of 150 patients. RESULTS: The trial was stopped due to a lack of recruitment, and the follow-up was completed in February 2023. Among 234 randomized patients of 300 planned patients, the primary outcome was available for 224 patients (110 high-dose and 114 standard-dose dexamethasone; median [interquartile range (IQR)] age, 59.0 [48.5-66.0] years; 130 [58.0%] were receiving noninvasive or invasive mechanical ventilation at baseline). The mean number of 28-day ventilator-free days was 8.9 (± 11.5) days for high-dose dexamethasone and 8.0 (± 10.7) days for standard-dose dexamethasone, with an absolute difference of + 0.81 days (95% CI - 2.12-3.73 days). None of the prespecified secondary outcomes, including adverse events, differed between the groups. CONCLUSIONS: Despite not reaching its prespecified enrollment, there was no signal to either benefit or harm high-dose dexamethasone over standard-dose dexamethasone in patients with COVID-19 and moderate-to-severe ARDS.

CONTEXT: Noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP) was introduced as a new entity replacing the diagnosis of noninvasive encapsulated follicular variant of papillary thyroid carcinoma (PTC). Significant variability in the incidence of NIFTP diagnosed in different world regions has been reported. OBJECTIVE: To investigate the rate of adoption of NIFTP, change in practice patterns, and uniformity in applying diagnostic criteria among pathologists practicing in different regions. METHODS: Two surveys distributed to pathologists of the International Endocrine Pathology Discussion Group with multiple-choice questions on NIFTP adoption into pathology practice and whole slide images of 5 tumors to collect information on nuclear score and diagnosis. Forty-eight endocrine pathologists, including 24 from North America, 8 from Europe, and 16 from Asia/Oceania completed the first survey and 38 the second survey. RESULTS: A 94% adoption rate of NIFTP by the pathologists was found. Yet, the frequency of rendering NIFTP diagnosis was significantly higher in North America than in other regions (P = .009). While the highest concordance was found in diagnosing lesions with mildly or well-developed PTC-like nuclei, there was significant variability in nuclear scoring and diagnosing NIFTP for tumors with moderate nuclear changes (nuclear score 2) (case 2, P < .05). Pathologists practicing in North America and Europe showed a tendency for lower thresholds for PTC-like nuclei and NIFTP than those practicing in Asia/Oceania. CONCLUSION: Despite a high adoption rate of NIFTP across geographic regions, NIFTP is diagnosed more often by pathologists in North America. Significant differences remain in diagnosing intermediate PTC-like nuclei and respectively NIFTP, with more conservative nuclear scoring in Asia/Oceania, which may explain the geographic differences in NIFTP incidence.
