Povzetek: The present article constitutes a revision of the decapod crustacean species Xanthopsis bodracus Makarenko, 1956 from the early Lutetian (Eocene, Palaeogene) of the Crimean Peninsula, southern Ukraine. The distinctive morphological characteristics of Xanthopsis bodracus enable its classification within the genus Harpactoxanthopsis Via Boada, 1959, as the type series of Xanthopsis bodracus precisely aligns with the diagnostic criteria of this genus. Of the five species in the genus Harpactoxanthopsis, Xanthopsis bodracus is morphologically closest to Harpactoxanthopsis quadrilobatus(Desmarest, 1822). However, there are currently insufficient grounds to confidently synonymise Xanthopsis bodracuswith Harpactoxanthopsis quadrilobatus, as the poorly preserved type material, of which only a part has been preserved, does not allow this. In view of this, Xanthopsis bodracus has been revised as Harpactoxanthopsis sp. The Palaeogene decapod assemblages of Crimea consist of five genera including Coeloma A. Milne-Edwards, 1865, Protocallianassa Beurlen, 1930, Arcticocarcinus Shweitzer et al., 2016, Xanthopsis M’Coy, 1849, and Harpactoxanthopsis Via Boada, 1959.

Povzetek: Introduction: Functional hypogonadism, a manifestation of testosterone deficiency in simultaneously present comorbidities, profoundly impairs quality of life in men with overweight and obesity - yet remains persistently under-recognized in clinical practice. Findings: Lifestyle modification constitutes first-line therapy, while pharmacological and surgical interventions increasingly complement it. Both promote substantial weight loss and may reverse obesity-related hypogonadism; bariatric surgery, in particular, elicits marked rises in circulating testosterone but entails risks of bone demineralization and uncertain long-term reproductive sequelae. Notwithstanding, testosterone deficiency itself represents a key driver of secondary osteoporosis, insulin resistance, anemia, fatigue, and depression as well as sexual symptoms. Glucagon-like peptide-1 receptor agonists (GLP-1RAs) have redefined obesity therapy through profound weight reduction and cardiometabolic benefit, yet concomitant losses of lean mass raise concern over sarcopenia and skeletal fragility. Conclusion: This focused review article aims to present a comprehensive update on the latest data concerning combining testosterone therapy with contemporary anti-obesity pharmacotherapy as a new standard of care for obese men with functional hypogonadism, uniting metabolic, vascular, sexual, cognitive, and skeletal benefits within a comprehensive strategy to fortify corporeal resilience and enhance quality of life.

Povzetek: Background and Objectives: Robot-assisted procedures represent a significant advancement in minimally invasive liver resection techniques. Nonetheless, the introduction of a novel surgical technique in a new environment necessitates meticulous planning and a gradual, stepwise approach. This study describes the adoption of a robotic surgical platform for liver resection at a high-volume tertiary care center. Materials and Methods: We retrospectively analyzed data that had been prospectively collected from fifty robot-assisted liver resections. Descriptive statistics, including frequencies, percentages, means/medians, and standard deviations, were employed for description and summary. Results: The median operative duration was 166 min (range: 85–400 min), with an average intraoperative blood loss of 200 mL (range: 50–1000 milliliters). Intraoperative or postoperative blood transfusion was required in 8% of patients. Conversion to open resection was necessary in one patient (2%). The mean duration of hospitalization was 5 days (range: 3–20 days), with a 30-day readmission rate of 6% and no mortality within 90 days. Postoperative complications classified as Clavien-Dindo grade 3 or higher were observed in five patients (10%). The mean tumor size varied according to pathology: 58.5 mm (range: 30–120 mm) in the hepatocellular carcinoma group; 27.4 mm (range: 10–32 mm) in the secondary malignancy group; and 42.6 mm (range: 24–60 mm) in the intrahepatic cholangiocarcinoma group. The median number of lymph nodes harvested during lymphadenectomy (IHHCA/GBCA) was 5.4, ranging from 1 to 11. The R0 resection rate for malignant tumors was 88.2% (of 30/34). Conclusions: This study validates the safe integration of robot-assisted surgery into liver disease treatment, supported by our initial experience. Despite its technical advantages, robotic-assisted liver surgery remains complex and demanding. Structured robotic training within established programs, meticulous patient selection, and a stepwise implementation approach are critical during the early phases to optimize the outcomes.

Povzetek: Objectives: The goal of this study is to document outcomes of ablation for high-risk accessory pathways in paediatrics using 3D mapping systems with minimal to zero fluoroscopy. Methods: It is a cross-sectional, multicentre study, conducted between 2013 and 2023, and involving four different centres in Hungary, Croatia, Kuwait, and Slovenia. Results: A total of 128 procedures were performed on 111 patients. The cohort included 57.8% anteroseptal (AS) pathways and 42.2% midseptal (MS) pathways. The mean follow-up time was 2.0 ± 2.1 years. Cryoablation was used in 72.7% of the cases, and radiofrequency ablation was used in 27.3%. The EnSite Precision™ Cardiac Mapping System was the predominant system used. The overall acute success rate was 89.1%, with recurrence rates at 17.2% with similar results regardless of the type of energy used. The success rate was not significantly different between AS and MS substrates. The age and weight of the patient had no bearing on the outcomes (median age and weight were 13 years and 52 kg, respectively). The complications rate was at 4.69% and included transient AV block (three patients), hematoma (one patient), right bundle branch block (one patient), and possible permanent complete AV block (one patient). Fluoroscopy was utilized in 18 cases, with a fluoroscopy time mean of 3 min and 45 s. Conclusions: MS and AS AP in paediatric patients can be treated effectively with either RF or cryoablation and with a low dose of radiation using 3D mapping systems, with excellent acute success rates and low complication rates.
