05). In both groups, salivary concentrations of all markers were lower (P less then .05), compared with those values in serum. We observed positive correlation between serum and salivary concentrations of all markers studied (P less then .05). CONCLUSION From the data, we conclude that investigation using saliva specimens is a noninvasive, simple, and effective tool for screening of biochemical parameters. © American Society for Clinical Pathology 2019.

If an isolation gown is ineffective, the patient and provider have a potential breach of safety and increased infection risk. This study compared the bacterial permeability of differently rated, commonly uses isolation gowns to assess their effectiveness in preventing simulated bacterial transmittance, and thus contamination, from patient to provider. METHODS Serial dilutions of Staphylococcus epidermidis in sterile saline were applied to a simulated skin surface. Unrated and Levels 1 through 4 non-sterile isolation gowns contacted the solution, simulating patient contact. Both sides of the contaminated gowns were then cultured on blood agar by rolling a sterile swab across the gown and evenly inoculating the culture plate. Colony counts from inside and outside of the gowns were compared. Separately, S. buy SKF96365 epidermidis was placed on a sample of each gown and scanning electron microscopy was used to University Press on behalf of the British Occupational Hygiene Society.The Infectious Diseases Society of America has not met their burden of proof to establish that SEP-1 has increased unnecessary antibiotic usage. Strategies recommending delay in antibiotic administration for additional diagnostics in severe sepsis have not been shown to be safe. © The Author(s) 2020.

METHODS The new transitions process was initiated on a 32-bed medical/surgical unit. Demographics, reconciliation data, information on medication adherence barriers, medication recommendations, and time spent performing interventions were prospectively collected for 284 consecutive patients over 54 days after the pharmacy participation was completely implemented. Outcome data, including 30-day readmission rates and length of stay, were retrospectively collected. RESULTS When comparing metrics for all intervention patients to baseline metrics from the same months of the previous year, the readmission rate was decreased from 21.0% to 15.3% and mean length of stay decreased from 5.3 days to 4.4 days. Further improvement to a 10.2% readmission rate and a 3.6-day average length of stay were observed in the subgroup of intervention patients who received all components of the pharmacy intervention. Additionally, greater improvements were observed in intervention-period patients who received the full pharmacy intervention, as compared to those receiving only parts of the pharmacy intervention, with a 10.2-percentage-point lower readmission rate (10.2% vs 20.4%, P = 0.016) and a 1.7-day shorter length of stay (3.6 days vs. 5.3 days; 95% confidence interval, 0.814-2.68 days; P = 0.0003). For patients receiving any component of the pharmacy intervention, an average of 9.56 medication recommendations were made, with a mean of 0.89 change per patient deemed to be required to avoid harm and/or increased length of stay. CONCLUSION A comprehensive pharmacy intervention added to a transitions intervention resulted in an average of nearly 10 medication recommendations per patient, improved length of stay, and reduced readmission rates. © American Society of Health-System Pharmacists 2020.

Based on the patterns of the sacroiliac arthrogram, we explored possible indicators of technically difficult and technically easy injections into the SIJ including demographic features and anatomical features evident on preprocedural imaging. DESIGN Observational study. METHODS We evaluated 76 patients with painful SIJ (total 108 joints) diagnosed by SIJ injections. The sacroiliac arthrogram was graded as follows Grade (G) 0 = the margin of the joint was partially outlined; G1 = the margin was completely outlined; G2 = intraarticular space was substantially outlined; and G3 = intraarticular space was fully outlined. Two multivariable ordered logistic regression analyses were performed to test the relationships between gender, age, and Grade, as well as between computed tomography (CT) findings and grade. RESULTS In men, the totals by Grade were G0 = 8 (joints); G1 = 33; G2 = 3; and G3 = 0. In women, these were G0 = 4; G1 = 28; G2 = 22; and G3 = 10. The Grade was significantly higher in women and was also higher with age (P  less then  0.05). Regarding morphological features in CT, minor osteophytes increased the odds in favor of better Grades of arthrogram (odds ratio = 3.50). Substantial vacuum phenomena strongly increased the odds of better arthrograms (20.52). CONCLUSIONS Outlining the SIJ cavity fully is significantly more difficult in male patients of any age than in aged female patients. The presence of minor osteophytes and substantial vacuum phenomena on preprocedure CT scans can be reasonably reassuring to the practitioner that they are unlikely to encounter difficulties during injection. © The Author(s) 2020.

Pheromone gradients allow the cells to detect potential mating partners. Secreted pheromone degrading proteases steepen local gradients and allow fast recovery from the pheromone signal. The methylotrophic yeast Komagataella phaffii is a preferentially haploid species. Only under nitrogen starvation, mating genes are activated and the cells are able to undergo a full sexual cycle of mating and sporulation. It has been shown that, similar to other yeasts, K. phaffii requires the mating pheromone and pheromone surface receptor genes for efficient mating. The analysis of so far uncharacterized mating-type-specific genes allowed us to identify the K. phaffii α-factor protease gene YPS1-5. It encodes an aspartic protease of the yapsin family and is upregulated only in a-type cells under mating conditions. The phenotype of K. phaffiia-type strains with a deletion in the protease gene was found to be highly similar to the phenotype of Saccharomyces cerevisiae α-factor protease BAR1 deletion strains.
