The COVID-19 pandemic provided a commercial opportunity for traders marketing a range of ultraviolet (UV) radiation products for home-use disinfection. Due to concerns about the efficacy of such products and the potential for harmful levels of UV exposure to people, a range of products were purchased from on-line trading platforms. Spectral irradiance measurements were carried out to determine whether the products could be effective against the SARS-CoV-2 virus and whether they were likely to exceed internationally agreed exposure limits.  https://www.selleckchem.com/products/imd-0354.html  It was concluded that many of the devices were not effective and many of those that were potentially effective presented a risk to users.
  To identify organizational complementarities of adoption and use of electronic health records (EHRs) and assess what organizational strategies were associated with more advanced EHR use.
 
  Primary survey data of US hospitals combined with secondary data from the American Hospital Association Annual Survey and IT Supplement.
 
  In this cross-sectional study, we describe hospital organizational practices around EHR adoption and use and identify how these practices coalesce into distinct strategies. We then assess the association between those organizational strategies and adoption of advanced EHR functions.
 
  Primary data collection consisted of surveys sent to 797 US acute care hospitals in 2018-2019, with 451 complete respondents.
 
  There was significant variation in hospital organizational practices for EHR adoption and use. Factor analysis identified practices in three domains leadership engagement, human capital, and systems integration. Hospitals in the top quartile of the leadership engagement factor welue from their EHR investment may find it useful to know that there is an association between adoption of more advanced EHR functions, and engaging senior leadership as well as building connectivity between clinical and administrative systems.The Model for End-Stage Liver Disease score may have eliminated racial disparities on the waitlist for liver transplantation (LT), but disparities prior to waitlist placement have not been adequately quantified. We aimed to analyze differences in patients who are listed for LT, undergo transplantation, and die from end-stage liver disease (ESLD), stratified by state and race/ethnicity. We analyzed two databases retrospectively - the Center for Disease Control Wide-ranging OnLine Data for Epidemiologic Research (CDC WONDER) and the United Network for Organ Sharing (UNOS) databases from 2014-2018. We included patients aged 25-64 years who had a primary cause of death of ESLD and listed for transplant in the CDC WONDER and UNOS databases, respectively. Our primary outcome was the ratio of listing for LT to death from ESLD - listing to death ratio (LDR). Our secondary outcome was the transplant to listing and transplant to death ratios. Chi-squared and multivariable linear regression evaluated for differences between race/ethnicity. 135,367 patients died of ESLD, 54,734 patients were listed for transplant, and 26,571 underwent transplant. Patients were mostly male and White. The national LDR was 0.40, significantly lowest in Black patients (0.30), p less then 0.001. The national transplant to listing ratio was 0.48, highest in Black patients (0.53), p less then 0.01. The national transplant to death ratio was 0.20, lowest in Black patients (0.16), p less then 0.001. States that had an above-mean LDR had a lower transplant to listing ratio, but higher transplant to death ratio. Multivariable analysis confirmed Black race is significantly associated with a lower LDR and transplant to death ratio. Conclusion Black patients face a disparity in access to LT due to low listing rates for transplant relative to deaths from ESLD.The implementation of evidence-based psychotherapies often requires significant commitments of time and expense from mental health providers. Psychotherapy protocols with rapid and efficient training and supervision requirements may have higher levels of uptake in publicly funded clinics. Family-focused therapy (FFT) is a 4-month, 12-session treatment for bipolar and psychosis patients consisting of psychoeducation, communication training, and problem-solving skills training. In a pilot randomized trial, we compared two methods of training community clinicians in FFT (a) high intensity (n = 24), consisting of a 6-hour in-person didactic workshop followed by telephone supervision for every session with training cases; or (b) low-intensity training (n = 23), consisting of a 4-hour online workshop covering the same material as the in-person workshop followed by telephone supervision after every third session with training cases. Of 47 clinician participants, 18 (11 randomly assigned to high intensity, 7 to low) enrolled 34 patients with mood or psychotic disorders (mean age 16.5 ± 2.0 years; 44.1% female) in an FFT implementation phase. Expert supervisors rated clinicians' fidelity to the FFT manual based on taped family sessions. We detected no differences in fidelity scores between clinicians in the two training conditions, nor did patients treated by clinicians in high- versus low-intensity training differ in end-of-treatment depression or mania symptoms. Levels of parent/offspring conflict improved in both conditions. Although based on a pilot study, the results suggest that low-intensity training of community clinicians in FFT is feasible and can result in rapid achievement of fidelity benchmarks without apparent loss of treatment efficacy.Harvesting microalgae from liquid culture is a difficult issue to solve and is most commonly done through settling. However, settling is a slow process on its own and generally needs to be induced chemically or by introducing stress to the culture. Polymeric, cationic substances, such as cationised starch and chitosan, are often used for flocculation and settling. These large, positively charged molecules form large clusters with suspended particles in the liquid medium. In the present study, three natural organic flocculants (cationic starch, chitosan and acacia tannin S5T) were tested to harvest microalgal cultures grown in wastewater. Two microalgal species, one strain of Chlorella vulgaris and one strain of Scenedesmus obliquus, were cultured in municipal wastewater for different lengths of time, and settled using either cationic starch, chitosan or acacia tannin S5T. Results indicated that S5T worked with approximately the same efficiency in the two assayed species, although it requires a relatively high dosage to function (about 300 mg L-1 ), while the other two flocculants varied from species to species.
