    Abstract This work focuses on the development and analysis of a new multifunctional facade panel incorporating PCM in foam layers. The thermal performance was analysed recurring to a hotbox heat flux meter method to determine the thermal transmittance (U-value) and the main findings are presented. The experimental setup was based on the steady-state approach, using climatic chambers, assuring a stable thermal environment. Even small fractions of PCM achieved a small reduction in thermal amplitude. Numerical simulations using Ansys Fluent were developed to evaluate the performance of PCM use over a wide range of temperature boundary conditions and operating modes. These numerical models were calibrated and validated using the results of experimental tests, achieving a correlation factor of 0.9674, and, thus, accurately representing a real-world scenario. The decrement factor (f) was used to analyse the data. It was identified that the efficiency of the panel and size of the optimum region increased with the PCM fraction growth. The results showed the significant potential of the multi-layered panel, with the thermal regulator effect of the PCM incorporated, on indoor space temperature so as to reach good thermal comfort levels. The efficiency of the panel can be improved by nearly 50% depending on the input boundary conditions. The efficiency of the panel and the size of the optimum region increase with growth in the PCM fraction. The simulated behaviour was at an optimum when the input mean temperature was 20 °C for a room temperature of between 18-20 °C.

    Abstract A 57 year-old catheter dependent dialysed woman with systemic erithematous lupus and central vein stenosis underwent HeRO graft placement in right internal jugular vein. In the next months she had multiple arm infections and venous outflow component was removed after impossibility to perform second thrombectomy at 14 months. Over time the graft migrated distally (Figure 1), and patient developed skin ulceration and graft exposition (Figure 2). No important weight loss was noted. Arterial graft was removed surgically and she had kidney transplantation. Arterial graft removal when HeRO graft is abandoned should be considered.

    Abstract This retrospective cohort study aimed to identify risk factors for the failure of transfer of passive immunity (FPI) in preweaned dairy calves, explore its associations with morbidity, mortality, genetics, and determine a standardized cut-off point for FPI. Analyzing data from 6011 calves, factors such as sire predicted transmitted ability for milk (PTA), birth season, retained placenta (RP), total serum protein concentration (TSP), morbidity (neonatal calf diarrhea - NCD, bovine respiratory disease - BRD, tick-borne disease - TBD), mortality, and average daily weight gain (ADG) were considered. The calves were categorized into predominantly Gyr (PG) and predominantly Holstein (PH) genetic composition groups. Multivariate mixed logistic regression revealed optimal TSP cut-off points for predicting morbidity (7.6 g/dL) and mortality (6.9 g/dL). PH calves exhibited 1.35 times higher odds of FPI and 1.48 times greater odds of disease. Calves from multiparous cows and those born to dams with RP had increased FPI odds. Disease prevalence was 53%, with 41% NCD, 18% BRD, and 10% TBD. Season, parity, PTA, and birth weight were associated with disease odds, though FPI was not a reliable predictor. The mortality percentage was 6%, with PH calves and those with a positive PTA having higher odds. The ADG was 0.64 kg, and FPI-affected calves gained less weight. The study compared and identified various risk factors that potentially impact calf immunity. However, the use of a standardized cut-off point for FPI assessment was not effective in predicting morbidity and mortality at this specific farm.

    Abstract The hosing instability poses a feasibility risk for plasma-based accelerator concepts. We show that the growth rate for beam hosing in the linear regime (which is relevant for concepts that use a long driver) is a function of the centroid perturbation wavelength. We demonstrate how this property can be used to damp centroid oscillations by detuning the plasma response sufficiently early in the development of the instability. We also develop a new theoretical model for the early evolution of hosing. These findings have implications for the general control of an instability's growth rate.

    Abstract Introduction: Malignant biliary obstruction drainage is essential, since jaundice is associated with morbidity and mortality. Endoscopic retrograde cholangiopancreatography (ERCP) is the recommended procedure for biliary drainage, with percutaneous biliary drainage being the classic alternative in cases of unsuccessful ERCP. Recently, endoscopic ultrasound-guided biliary drainage has been emerged as a new option, with EUS-guided choledochoduodenostomy (EUS-CDS) being considered an effective and safe method in the drainage of distal obstructions of the common bile duct.
    Aim: The aim of the study was to evaluate the efficacy and safety of EUS-CDS performed in patients with distal malignant biliary obstructions, after failed ERCP.
    Methods: Single-center retrospective cohort study between July 2017 and June 2022 including all consecutive patients submitted to EUS-CDS in our center. The primary outcomes were "technical success" and "clinical success," defined as "resolution of jaundice or improvement in total serum bilirubin level above 50% at 7th day and above 75% at 30th day after the procedure." Secondary outcomes were procedure-related adverse events, endoscopic reintervention, and survival time.
    Results: EUS-CDS was performed in 20 patients (65.0% male; median age 76 years). The most frequent etiology for the biliary obstruction was pancreatic adenocarcinoma (
    Conclusion: EUS-CDS was effective in biliary decompression of malignant obstructions of the common bile duct, with high clinical success and a favorable safety profile.

    Abstract Calcifying odontogenic cysts (COCs) exhibit a diverse clinical course, commonly developing between the second and third decades of life, displaying no gender predilection. A 15-year-old female without medical history was under observation for a mixed lesion in the maxilla associated with an impacted tooth. She presented to the emergency department with sudden onset and worsening swelling of the left midface. Radiographic findings in the panoramic radiograph and a CT scan revealed a well-circumscribed mixed lesion localized in the left maxilla, extending into the left maxillary sinus and reaching the orbital floor. After an intercurrent infection of the cyst, the patient was hospitalized, received intravenous antibiotics, and went for surgical intervention under general anesthesia. Lesions that combine histological characteristics of two or more odontogenic tumors or individual cysts in the same location are called hybrid odontogenic lesions. This type of lesion poses a challenge for both pathologists and surgeons, because of its controversial histogenesis and poorly understood clinical evolution. The most common of these lesions are COCs associated with odontoma. Our case represents an exceptionally rare entity among odontogenic cysts.
