Die intraoperative Hyperpyrexie bei Osteogenesis imperfecta-Betroffenen
2000
The aim of this study was to evaluate the influence of different types of anesthesia upon the intra- and postoperative body temperature in osteogenesis imperfecta patients. The development of an intraoperative hyperpyrexia of unknown origin is a typical phenomenon in patients with osteogenesis imperfecta. Body temperatures of up to 40 degrees C are known to complicate the operation. Therefore, in a retrospective study, the pre-, intra- and postoperative body temperature curves of 45 operations under different anaesthesias were measured. Group A underwent a common balanced anaesthesia with the volatile anaesthetic Enfluran in combination with Fentanyl, while group B was operated on under tot…
EGFR tyrosine kinase inhibitor therapy continuation with high-dose hypofractionated radiotherapy in EGFR-mutated non-small cell lung cancer (NSCLC) p…
2020
e21580 Background: EGFR tyrosine kinase inhibitors (TKIs) represent the standard first-line therapy for advanced non-small cell lung cancer (NSCLC) patients with activating EGFR mutations. However, despite initial marked responses, tumors invariably develop acquired resistance to TKIs. Oligoprogression is commonly observed during treatment with oncogene-directed therapies, including EGFR TKIs, and refers to patients who experience disease progression only in limited sites as a result of heterogeneous mechanisms of resistance. The use of local ablative treatments for these resistant lesions may extend the duration of TKI therapy and potentially improve long-term disease control and survival…
Moderate hypofractionated helical tomotherapy for localized prostate cancer: preliminary report of an observational prospective study.
2019
Objective: To report preliminary findings of a phase II study exploring the clinical outcomes of moderate hypofractionated radiotherapy performed with helical tomotherapy (HT) using computed tomography–magnetic resonance imaging–based planning for localized prostate cancer. Methods: The phase II prospective study received ethics approval from our institutional ethics committee. A dose of 60 Gy/20 fractions for low–intermediate risk prostate cancer by means of HT was explored. Primary endpoints of the study were acute and late gastrointestinal (GI) and genitourinary (GU) toxicities. Secondary endpoints were quality of life and biochemical-free survival. Results: A total of 35 patients were i…
Integration of Indocyanine Green Analogs as Near‐Infrared Fluorescent Carrier for Precise Imaging‐Guided Gene Delivery
2020
Codelivery of diagnostic probes and therapeutic molecules often suffers from intrinsic complexity and premature leakage from or degradation of the nanocarrier. Inspired by the "Y" shape of indocyanine green (ICG), the dye is integrated in an amphiphilic lipopeptide (RNF). The hydrophilic segment is composed of arginine-rich dendritic peptides, while cyanine dyes are modified with two long carbon chains and employed as the hydrophobic moiety. They are linked through a disulfide linkage to improve the responsivity in the tumor microenvironment. After formulation with other lipopeptides at an optimized ratio, the theranostic system (RNS-2) forms lipid-based nanoparticles with slight positive z…
Dodatno svjedočanstvo. Fotografije u prozi Daše Drndić
2020
In this paper I will reflect on the role of photographs in the works of Daša Drndić. Mixing fictional and documentary modes is a characteristic feature of her texts. It is achieved among others by utilizing visual representations of the past. In my paper I aim to outline the strategies of visualization applied by the authoress (especially the traumatic, Holocaust-related experience), which materialize through photographs included in her works of literature. In the case of Drndić the visuals include for instance contemporary or archival photographs of places marked by the Holocaust and of Jewish inhabitants of Vienna as well as portraits of war criminals. Generally speaking, in her texts the…
Dosimetric effect of respiratory motion on planned dose in whole-breast volumetric modulated arc therapy using moderate and ultra-hypofractionation.
2021
Abstract Background and purpose The interplay effect of respiratory motion on the planned dose in free-breathing right-sided whole-breast irradiation (WBI) were studied by simulating hypofractionated VMAT treatment courses. Materials and methods Ten patients with phase-triggered 4D-CT images were included in the study. VMAT plans targeting the right breast were created retrospectively with moderately hypofractionated (40.05 Gy in 15 fractions of 2.67 Gy) and ultra-hypofractionated (26 Gy 5 fractions of 5.2 Gy) schemes. 3D-CRT plans were generated as a reference. All plans were divided into respiratory phase-specific plans and calculated in the corresponding phase images. Fraction-specific d…
H-ferritin and CD68+/H-ferritin+ monocytes/macrophages are increased in the skin of adult-onset Still's disease patients and correlate with the multi…
2016
Summary Adult-onset Still's disease (AOSD) patients may show an evanescent salmon-pink erythema appearing during febrile attacks and reducing without fever. Some patients may experience this eruption for many weeks. During AOSD, exceptionally high serum levels of ferritin may be observed; it is an iron storage protein composed of 24 subunits, heavy (H) subunits and light (L) subunits. The ferritin enriched in L subunits (L-ferritin) and the ferritin enriched in H subunits (H-ferritin) may be observed in different tissues. In this work, we aimed to investigate the skin expression of both H-and L-ferritin and the number of macrophages expressing these molecules from AOSD patients with persist…
Calorie Restriction in Adulthood Reduces Hepatic Disorders Induced by Transient Postnatal Overfeeding in Mice
2019
International audience; Impaired early nutrition influences the risk of developing metabolic disorders in later life. We observed that transient postnatal overfeeding (OF) in mice induces long-term hepatic alterations, characterized by microsteatosis, fibrosis associated with oxidative stress (OS), and stress-induced premature senescence (SIPS). In this study, we investigated whether such changes can be reversed by moderate calorie restriction (CR). C57BL/6 male mice pups were maintained during lactation in litters adjusted to nine pups in the normal feeding (NF) group and three pups in the transient postnatal OF group. At six months of age, adult mice from the NF and OF groups were randoml…
Mutations in ATP13A2 (PARK9) are associated with an amyotrophic lateral sclerosis-like phenotype, implicating this locus in further phenotypic expans…
2019
Background Amyotrophic lateral sclerosis [1] is a genetically heterogeneous neurodegenerative disorder, characterized by late-onset degeneration of motor neurons leading to progressive limb and bulbar weakness, as well as of the respiratory muscles, which is the primary cause of disease fatality. To date, over 25 genes have been implicated as causative in ALS with C9orf72, SOD1, FUS, and TARDBP accounting for the majority of genetically positive cases. Results We identified two patients of Italian and French ancestry with a clinical diagnosis of juvenile-onset ALS who were mutation-negative in any of the known ALS causative genes. Starting with the index case, a consanguineous family of Ita…
Incidence and risk factors of post-engraftment invasive fungal disease in adult allogeneic hematopoietic stem cell transplant recipients receiving or…
2015
Studies that analyze the epidemiology and risk factors for invasive fungal disease (IFD) after engraftment in alloSCT are few in number. This single-center retrospective study included 404 alloSCT adult recipients surviving > 40 days who engrafted and were discharged without prior IFD. All patients who received >= 20 mg/day of prednisone were assigned to primary oral prophylaxis (itraconazole or low-dose voriconazole). The primary end point was the cumulative incidence (CI) of probable/proven IFD using the European Organization for Research and Treatment of Cancer and Mycoses Study Group (EORTC/MSG) criteria. The independent prognostic factors after multivariate analyses were used to constr…
