Eu3+ -activated Ba2 V2 O7 (Ba2-x V2 O7 xEu3+ ) phosphor materials were synthesized using a hydrothermal method and different concentrations of europium (x = 0.01, 0.02, 0.03, 0.04, and 0.05%). SD-208 mw Phase purity, structural, morphological, optical, and luminescence characteristics of the as-synthesized phosphors were studied using powder X-ray diffraction (XRD), high resolution scanning electron microscopy, UV-visible spectroscopy, and fluorescence spectrometry. The recorded XRD patterns of the as-synthesized phosphors were indexed and predicted to be a triclinic structure. A cube-like morphology was obtained for the as-prepared samples. Broad absorption in the UV region from 200 nm to 380 nm was observed and the good transparency in the visible region at 400-800 nm originated from the [VO4 ]3- group charge transfer (CT) transition. The broad emission peak centred at 499 nm was due to the CT band of the [VO4 ]3- group. Also, a sharp peak observed at 613 nm was due to the electric dipole transition of 5 D0 →7 F2 of Eu3+ ions that occupied the lattice sites without inversion symmetry for all concentrations. The colour qualities of the as-prepared samples were calculated using Commission International de l'Eclairage coordinates. The colour-rending index (CRI) value was 86 for the Ba1.97 V2 O7 0.03Eu3+ phosphor. Furthermore, a WLED with a high CRI value of 95 was achieved by coupling the 3 W 356 nm near-UV light-emitting diode (LED) chip with the Ba2-x V2 O7 xEu3+ phosphor. These results suggested that the as-prepared phosphor materials are potential candidates for fabrication of near-UV chip excited WLEDs.Herbal tonic and adaptogens are often used to improve overall well-being. However, few clinical evidence supports their use and their safety is not known before marketing. In this context, the aim of our study was to analyze the spontaneous reports of suspected adverse reactions (ARs) to performance enhancing herbal dietary supplements collected by the Italian Phytovigilance System. Between March 2002 and September 2020, 110 spontaneous reports were collected, 58 of which related to products containing botanicals, alone or in association. Twenty-three serious reactions were reported, 21 of which required hospitalization, one was life-threatening and another caused disability. Dermatological and cardiovascular reactions were the most frequent. Hepatic ARs were the most serious (9 out of 10). A positive dechallenge was indicated in 69% of cases, while a positive rechallenge occurred in 15%. Concomitant use of other products was present in 18 reports (31%), while predisposing conditions were indicated in 17 (29%). Present data highlight safety concerns on herbal dietary supplements used as cognitive and physical performance enhancers, mainly due to their quality and use without expert supervision. Considering that postmarketing surveillance is not required for these products, spontaneous reports represent the only tool to point out risks related to food supplements.
To analyse the psychometric properties of the De Jong Gierveld Loneliness Scale, 6-item version (DJGLS-6), in a multiethnic sample of older Chilean adults.
A cross-sectional study was designed using a sample of 800 older people, and 71% were self-declared indigenous. Data quality and acceptability, internal consistency, and construct and structural validity of DJGLS-6 were analysed. The scale was also analysed according to the Rasch model.
The DJGLS-6 scored higher for the non-indigenous group than for Aymara and Mapuche (P<.001). KR-20 coefficients (internal consistency) for emotional loneliness subscale reached 0.44 for Aymara and Mapuche and 0.62 for non-indigenous, and from 0.73 (non-indigenous) to 0.86 (Aymara) for social loneliness subscale. The confirmatory factor analysis identified one dimension. None of the two subscales fit the Rasch model.
The results indicate that DJGLS-6 is a reliable and adequate scale for non-indigenous Chilean older people. However, it should be culturally adapted to indigenous ethnic minorities.

COVID-19-associated pulmonary aspergillosis (CAPA) has emerged as an invasive fungal disease, often affecting previously immunocompetent, mechanically ventilated, intensive care unit (ICU) patients. Incidence rates of 3.8%-33.3% have been reported depending on the geographic area, with high (47%) mortality.
Here, we describe a single-centre prospective case series with CAPA cases from both the first (March-May, n=5/33) and second (mid-September through mid-December, n=8/33) COVID-19 wave at a 500-bed teaching hospital in the Netherlands.
In the first COVID-19 wave, a total of 265 SARS-CoV-2 PCR-positive patients were admitted to our hospital of whom 33 needed intubation and mechanical ventilation. In the second wave, 508 SARS-CoV-2 PCR-positive patients were admitted of whom 33 needed mechanical ventilation. Data were prospectively collected.
We found a significant decrease in COVID-19 patients needing mechanical ventilation in the ICU in the second wave (p<.01). From these patients, however, a hignd wave. Numbers are too small to determine whether there is a true difference in CAPA incidence in mechanically ventilated patients between the two waves, and whether it could be attributed to dexamethasone SARS-CoV-2 therapy.Metastatic spinal cord compression (MSCC) is a condition that impacts directly on the patient's prognosis.
The study purpose was to identify predictors of overall survival in non-small-cell lung cancer (NSCLC) patients with MSCC.
A cohort study involving NSCLC patients enrolled between 2008 and 2017 was performed. Sixty-four patients treated with short-course radiotherapy were included. Clinical and socio-demographic data were extracted from medical records. Data were analysed using survival analysis and Cox proportional hazard regression analysis.
The median survival time was 2.5months (95% CI 1.6-3.5). Patients >60years had shorter survival than younger patients (HR 1.85; 95% CI 1.06-3.24; p=0.02), and patients with performance status (PS) >2 had shorter survival than those with PS≤2 (HR 1.93; 95% CI 1.12-3.33; p=0.01).
This study found worse PS and higher age are independent predictors of overall survival in NSCLC patients with MSCC treated with short-course radiotherapy after adjusting the potential confounding factors (PS, age and target therapy).
