    Radiation-induced cystitis is a common side effect of radiotherapy (RT) to the pelvic area. Hyaluronic acid (HA) and chondroitin sulfate (CS) are components of the urothelial mucosa and positive results have been obtained for intravesical HA/CS instillations for the treatment of urinary tract infections and bladder pain syndrome. HA/CS may also have a protective effect against RT bladder toxicity. To investigate whether HA and CS protect the urothelium during RT, alleviate lower urinary tract symptoms, and improve quality of life. This multicentre randomised controlled trial was conducted across seven centres in four countries. Male patients aged ≄18 yr scheduled to undergo primary intensity-modulated radiotherapy for localised prostate cancer were enrolled. Patients were randomised to intravesical HA/CS plus an oral formulation of curcumin, quercetin, HA, and CS (group A) or no treatment (group B). The primary endpoint was absolute changes from baseline to follow-up in urinary domain scores for the Expanded Prostate Cancer Index Composite (EPIC), the International Consultation on Incontinence Questionnaire-Male Lower Urinary Tract Symptoms (ICIQ-MLUTS), and the EuroQol Group EQ-5D-5L questionnaire. Data analysis for efficacy and safety outcomes was performed using an intention-to-treat (ITT) approach; the ITT population was defined as all randomised patients. Of 57 patients screened, 49 were enrolled and randomly assigned to either active treatment (group A, n = 25) or the control (group B, n = 24). Three patients in the control group withdrew after randomisation. Changes from baseline to 12 mo were worse in the control group for subtotal scores for urinary symptoms and impact of symptoms on quality of life and for the total score (p = 0.05, p = 0.003, and p = 0.008, respectively). There was a significant time × group interaction in favour of active treatment for the incontinence symptom score (p = 0.011) and bother score (p = 0.017). The absence of a sham procedure and/or placebo is the main limitation. Our results suggest that intravesical HA/CS in combination with an oral formulation may reduce urinary symptoms and improve QoL at short-term (1 yr) follow-up. We investigated whether hyaluronic acid (HA) and chondroitin sulfate (CS) have a protective effect against the bladder toxicity of radiotherapy for prostate cancer. HA/CS used for weekly bladder irrigation for 6 wk and given orally with curcumin and quercetin for 12 wk reduced urinary incontinence symptoms and bother measured at 1-year follow-up. This may hold promise as a preventive treatment if the results are confirmed in further trials. Our findings show a beneficial effect of intravesical hyaluronic acid (HA)/chondroitin sulfate (SC) plus the oral combination of curcumin, quercetin, HA, and CS for prevention of acute and late (1 yr) radiation-induced cystitis and improvement in quality of life. The current strategy may have a place among treatment options for the prevention of radiation-induced bladder complications, which until now have been limited to symptom-relieving and temporary modalities

    Quantum ESPRESSO: a modular and open-source software project for quantum simulations of materials

    Get PDF
    Quantum ESPRESSO is an integrated suite of computer codes for electronic-structure calculations and materials modeling, based on density-functional theory, plane waves, and pseudopotentials (norm-conserving, ultrasoft, and projector-augmented wave). Quantum ESPRESSO stands for "opEn Source Package for Research in Electronic Structure, Simulation, and Optimization". It is freely available to researchers around the world under the terms of the GNU General Public License. Quantum ESPRESSO builds upon newly-restructured electronic-structure codes that have been developed and tested by some of the original authors of novel electronic-structure algorithms and applied in the last twenty years by some of the leading materials modeling groups worldwide. Innovation and efficiency are still its main focus, with special attention paid to massively-parallel architectures, and a great effort being devoted to user friendliness. Quantum ESPRESSO is evolving towards a distribution of independent and inter-operable codes in the spirit of an open-source project, where researchers active in the field of electronic-structure calculations are encouraged to participate in the project by contributing their own codes or by implementing their own ideas into existing codes.Comment: 36 pages, 5 figures, resubmitted to J.Phys.: Condens.

    Sigh in patients with acute hypoxemic respiratory failure and acute respiratory distress syndrome: the PROTECTION pilot randomized clinical trial

    Get PDF
    Background: Sigh is a cyclic brief recruitment manoeuvre: previous physiological studies showed that its use could be an interesting addition to pressure support ventilation to improve lung elastance, decrease regional heterogeneity and increase release of surfactant. Research question: Is the clinical application of sigh during pressure support ventilation (PSV) feasible? Study design and methods: We conducted a multi-center non-inferiority randomized clinical trial on adult intubated patients with acute hypoxemic respiratory failure or acute respiratory distress syndrome undergoing PSV. Patients were randomized to the No Sigh group and treated by PSV alone, or to the Sigh group, treated by PSV plus sigh (increase of airway pressure to 30 cmH2Ofor 3 seconds once per minute) until day 28 or death or successful spontaneous breathing trial. The primary endpoint of the study was feasibility, assessed as non-inferiority (5% tolerance) in the proportion of patients failing assisted ventilation. Secondary outcomes included safety, physiological parameters in the first week from randomization, 28-day mortality and ventilator-free days. Results: Two-hundred fifty-eight patients (31% women; median age 65 [54-75] years) were enrolled. In the Sigh group, 23% of patients failed to remain on assisted ventilation vs. 30% in the No Sigh group (absolute difference -7%, 95%CI -18% to 4%; p=0.015 for non-inferiority). Adverse events occurred in 12% vs. 13% in Sigh vs. No Sigh (p=0.852). Oxygenation was improved while tidal volume, respiratory rate and corrected minute ventilation were lower over the first 7 days from randomization in Sigh vs. No Sigh. There was no significant difference in terms of mortality (16% vs. 21%, p=0.342) and ventilator-free days (22 [7-26] vs. 22 [3-25] days, p=0.300) for Sigh vs. No Sigh. Interpretation: Among hypoxemic intubated ICU patients, application of sigh was feasible and without increased risk

    The goitrous Salting Madonnas: Iconography of goiter in religious portraits

    No full text
    Introduction: George Salting was an art collector, who bequeathed his collection of paintings to the National Gallery of London. The present investigation has revealed five portraits of five different artists belonging to this collection in which the Holy Mother holding the child has been portrayed with a variable grade of thyroid gland enlargement. The name Salting, applied to the Madonnas with child by Antonello da Messina, Robert Campin, Dirk Bouts, Cima da Conegliano, and Andrea del Verrocchio, denotes George Salting, the collector who donated the masterworks to the gallery in 1910. Materials and Methods: The five paintings were analyzed to determine the accuracy of the diagnosis of neck swelling and the underlying iconographical significance of this depiction, which is relatively uncommon in religious artworks. Results: The present investigation highlighted an abnormal profile of the neck of the Virgin Mary, which is suggestive of a presumptive medico-artistic diagnosis of goiter. The inclusion of thyroid swelling in a holy sitter is relatively uncommon and is related to specific meanings that the painter wanted to illustrate in the work, the reasons for which are herein discussed. Conclusions: It seems likely that the integration of the goiter in the paintings is a stylistic hallmark. Indeed, the depiction of a slight neck enlargement is most probably a rhetorical tendency of representing an idealized female beauty, especially in holy sitters, imbued by a balanced neck and graceful body. At the same time, it probably also reflects better anatomic accuracy and knowledge of Renaissance artists applied toward a more realistic and precise representation of subjects
