RESUMO

Coherence Imaging Charge Exchange Recombination Spectroscopy (CICERS) is an imaging diagnostic installed in Wendelstein 7-X from which 2D maps of ion temperature (Ti) and impurity density (nZ) are obtained. The improved spatial resolution and coverage, as compared to standard Charge eXchange Recombination Spectroscopy (CXRS), with which these parameters can be assessed, come at the expense of spectral resolution, requiring the development of new strategies to isolate the active charge exchange contribution from passive and Bremsstrahlung radiation. In this work, a new approach based on the modeling of background radiation is presented and applied to the derivation of 2D Ti maps. These are compared to the Ti profiles derived from standard CXRS, which found excellent agreement up to the edge (ρ > 0.8). The CICERS view is implemented in the pyFIDAsim code, which is used to provide further insight into the spatial localization of the radiation as measured by the diagnostic. Moreover, an absolute intensity calibration is carried out, and, coupled with pyFIDAsim, the first 2D nC maps are obtained and validated against CXRS data.

RESUMO

This paper presents an overview of recent hardware extensions and data analysis developments to the Wendelstein 7-X visible core spectroscopy systems. These include upgrades to prepare the in-vessel components for long-pulse operation, nine additional spectrometers, a new line of sight array for passive spectroscopy, and a coherence imaging charge exchange spectroscopy diagnostic. Progress in data analysis includes ion temperatures and densities from multiple impurity species, a statistical comparison with x-ray crystal spectrometer measurements, neutral density measurements from thermal passive Balmer-alpha emission, and a Bayesian analysis of active hydrogen emission, which is able to infer electron density and main ion temperature profiles.

RESUMO

INTRODUCTION AND OBJECTIVE: To verify the impact of delay on biochemical and clinical outcomes for patients presenting to the emergency department (ED) with acute renal colic. MATERIALS AND METHODS: Data were retrospectively collected from three institutions of two European countries between 01 January and 30 April 2020. Patients who presented to the ED with unilateral or bilateral renal colic caused by urolithiasis confirmed by imaging tests during the study period were included. A presentation after 24 h since the onset of symptoms was considered a delay. Patients presenting before 24 h from the symptom onset were included in Group A, while the patients presenting after 24 h in Group B. Clinical and biochemical parameters and management were compared. RESULTS: A total of 397 patients who presented to ED with confirmed urolithiasis were analyzed (Group A, n = 199; Group B, n = 198. The median (IQR) delay in presentation was 2 days (1,5-4). At presentation, no statistically significant differences were found amongst the two groups of patients regarding presenting symptoms such as fever and flank pain, and the median serum levels of creatinine, C reactive protein and white blood cells. No differences were found in terms of conservative or operative management. CONCLUSION: Delay in consultation >24 h is not associated with worsening biochemical parameters and clinical outcomes. Most patients with acute loin pain do not necessarily need urgent attendance to the ED and may be managed in the outpatients.

RESUMO

Penile granulomas has been rarely reported in the setting of BCG instillations. We present a 70 year-old male with multiple penile granulomas during BCG instillations due a high-grade urothelial bladder cancer. Histopathological study revealed granulomatous structures with central necrosis as seen after BCG therapy. Local treatment with cryotherapy has been shown to be effective. This case emphasizes the importance to suspect this adverse effect in patients under BCG treatment.

RESUMO

INTRODUCTION: We hypothesized that the recent COVID-19 pandemic may lead to a delay in renal colic patients presenting to the Emergency Department due to the fear of getting infected. This delay may lead to a more severe clinical condition at presentation with possible complications for the patients. MATERIAL AND METHODS: Retrospective review of data collected from three institutions from Spain and Italy. Patients who presented to Emergency Department with unilateral or bilateral renal colic caused by imaging confirmed urolithiasis during the 45 days before and after each national lockdown were included. Data collected included patients' demographics, biochemical urine and blood tests, radiological tests, signs, symptoms and the therapeutic management. Analysis was performed between two groups, Group A: patients presenting prior to the national lockdown date; and Group B: patients presenting after the national lockdown date. RESULTS: A total of 397 patients presented to Emergency Department with radiology confirmed urolithiasis and were included in the study. The number of patients presenting to Emergency Department with renal/ureteric colic was 285 (71.8%) patients in Group A and 112 (28.2%) patients in Group B (p<0.001). The number of patients reporting a delay in presentation was 135 (47.4%) in Group A and 63 (56.3%) in Group B (p=0.11). At presentation, there were no statistical differences between Group A and Group B regarding the serum creatinine level, C reactive protein, white blood cell count, fever, oliguria, flank pain and hydronephrosis. In addition, no significant differences were observed with the length of stay, Urology department admission requirement and type of therapy. CONCLUSION: Data from our study showed a significant reduction in presentations to Emergency Department for renal colic after the lockdown in Spain and Italy. However, we did not find any significant difference with the length of stay, Urology department admission requirement and type of therapy.

RESUMO

ETHNOPHARMACOLOGICAL RELEVANCE: Litsea glaucescens (Lauraceae) has been used in Mexican Traditional Medicine to relieve illness related to central nervous system, such as epilepsy, fright and sadness. In this study, L. glaucescens essential oil properties on central nervous system were evaluated in mice using different behavioral tests. MATERIALS AND METHODS: The essential oil was obtained by hydrodistillation and analyzed by GC/MS. Identification of major compounds was also carried out by comparison with authentic samples. The psychopharmacological profile of L. glaucescens essential oil, and some its major compounds, were evaluated in mice using several experimental models: forced swimming test (FST: Antidepressant-like activity), open field test (OFT: Spontaneous locomotor activity), elevated plus-maze (EPM: Anxiolytic-like activity), exploratory cylinder (ECT: Sedative-like activity), rotarod (motor coordination) and traction performance (myo-relaxant effect) the essential oil and active principles was administered intraperitoneally. RESULTS: The essential oil showed antidepressant-like activity at doses of 100 and 300 mg/Kg. The monoterpenes ß-pinene and linalool were identified as the two main active principles of the essential oil, and showed antidepressant-like and sedative-like activity. Eucalyptol, limonene and α-pinene they did not show antidepressant-like activity, and were not further tested. CONCLUSIONS: L. glaucescens essential oil showed antidepressant activity, ß-pinene and linalool were identified as its active principles. These results support the use of L. glaucescens in Mexican Traditional Medicine for the treatment of sadness.

RESUMO

In many works performed in different countries, including Cuba, the microorganism Helicobacter pylori (Hp) is involved in the etiopathogenesis and relapse of gastroduodenal ulcer (GDU). In a previous work, we saw that under treatment of Colloidal bismuth subcitrate (CBS) or Metronidazole (M) alone during 4 weeks, the percentage of Hp clearance obtained was very low. So, we decided to extend the treatment with a unique drug up to 6 weeks or to make a combination of drugs during 4 weeks. 114 patients with GDU endoscopic diagnosis and Hp positive by urease test antral biopsy were located in 5 schedules of treatment: 1) CBS 480 mg daily during 6 weeks; 2)M 1 g daily during 6 weeks; 3) CBS 480 mg daily plus M 750 mg daily during 4 weeks; 4) CBS 480 mg daily plus Amoxycillin (A) 1500 mg daily during 4 weeks and 5) M 750 mg daily plus Amoxycillin 1500 daily during 4 weeks. Endoscopy and urease test were repeated at the end of treatment. Healing of ulcer was obtained in 83.3%; 36.4%; 89.2%; 91.9% and 54.6% respectively. Hp clearance was reached in 55.6%; 27.3%; 67.6%; 70.3% and 27.3% respectively. So, the schedules of treatment less effective (concerning both healing and Hp clearance) were M during 6 weeks and M plus A during 4 weeks. It has been reported that Hp strains may become resistant to nitroimidazolics in the course of treatment and that this resistance could be diminished by the coadministration of CBS. We recommend in GDU-Hp positive a treatment with CBS during 6 weeks or the combination of CBS, which action is basically local, with an antibiotic such as M (no more than two weeks) or Amoxycillin during 4 weeks.
