nection implant was used, the crown height did not affect the detorque values, and 14-mm crowns performed similarly to the shorter crowns in terms of torque loss after cyclic loading. However, survival of the 14-mm crown-implant complex was lower, resulting in screw and implant fractures.
When the tested internal connection implant was used, the crown height did not affect the detorque values, and 14-mm crowns performed similarly to the shorter crowns in terms of torque loss after cyclic loading. However, survival of the 14-mm crown-implant complex was lower, resulting in screw and implant fractures.
Although the clinical use of self-adhesive flowable composite resins is convenient, the decision to use flowable or conventional composite resin remains controversial.
The purpose of this systematic review and meta-analysis was to assess the invitro bond strength of self-adhesive flowable composite resins to enamel or dentin compared with conventional composite resins using etch-and-rinse or self-etch adhesive systems.
Two independent reviewers performed searches in the PubMed (MEDLINE), Cochrane Wiley, Web of Science, Scopus, and Google Scholar databases for studies reporting on the bond strength of self-adhesive flowable and conventional composite resins to enamel and dentin published from January 2010 up to September 2020. A meta-analysis software program was used for the meta-analysis. Comparisons were conducted using standardized mean differences considering the random-effects model (α=.05).
Twenty-two studies were considered for the meta-analysis. Immediate and long-term bond strength to enamel was improved when a conventional composite resin was used in combination with an adhesive system (P<.001). Bond strength to dentin was improved by using an adhesive system in combination with a conventional composite resin (P<.001).
The bond strength of self-adhesive flowable composite resins is lower than that of conventional composite resins, indicating limited ability to bond to enamel and dentin.

Since industrialization, metal micronutrients in these regions have increased. Phytoplankton use metals as micronutrients in metabolic processes, but in excess, had deleterious effects. In coastal systems, picoeukaryotes represent a diverse and abundant group with widespread distribution and fundamental roles in biogeochemical cycling. Chroman 1 ic50 We combined different approaches to explore picoeukaryotes seasonal variability in a chronically metal polluted coastal area at the south-eastern Pacific Ocean. Through remote and field measurements to monitor environmental conditions and 18S rRNA gene sequencing for taxonomic profiling, we determined metal chronic effect on picoeukaryote community's structure. Our results revealed a stable richness and a variable distribution of the relative abundance, despite the physicochemical seasonal variations. These results suggest that chronic metal contamination influences temporal heterogeneity of picoeukaryote communities, with a decoupling between abiotic and biotic patterns.
To report long-term outcomes after deep hypothermic circulatory arrest (DHCA) with or without perioperative blood or blood products.
All patients who underwent proximal aortic surgery with DHCA from 2011 to 2018 were propensity matched according to baseline characteristics. Primary outcomes included short- and long-term mortality. Stratified Cox regression analysis was performed for significant associations with survival.
A total of 824 patients underwent aortic replacement requiring circulatory arrest. After matching, there were 224 patients in each arm (transfusion and no transfusion). All baseline characteristics were well matched, with a standardized mean difference (SMD)<0.1. Preoperative hematocrit (41.0 vs 40.6; SMD=0.05) and ejection fraction (57.5% vs 57.0%; SMD=0.08) were similar between the no transfusion and blood product transfusion cohorts. Rate of aortic dissection (42.9% vs 45.1%; SMD=0.05), hemiarch replacement (70.1% vs 70.1%; SMD=0.00), and total arch replacement (21.9% vs 23.2%; SMD=0.03) were not statistically different. Cardiopulmonary bypass and cross-clamp time were higher in the blood product transfusion cohort (P<.001). Operative mortality (9.4% vs 2.7%; P=.003), stroke (7.6% vs 1.3%; P=.001), reoperation rate, pneumonia, prolonged ventilation, and dialysis requirements were significantly higher in the transfusion cohort (P<.001). In stratified Cox regression, transfusion was an independent predictor of mortality (hazard ratio, 2.62 [confidence interval, 1.47-4.67]; P=.001). One- and 5-year survival were significantly reduced for the transfusion cohort (P<.001).
In patients who underwent aortic surgery with DHCA, perioperative transfusions were associated with poor outcomes despite matching for preoperative baseline characteristics.

To determine whether the homeless population experiences disparities in care and communication during inpatient hospitalizations in a safety-net hospital.
We administered a modified Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) survey to 112 age-sex- and education matched homeless and non-homeless adults at a university-affiliated-safety-net hospital from December 2017 through March 2018 and performed a retrospective review of medical records. Linear regression models were used to assess differences in responses to survey subscales, length of stay and other measures.
Homeless participants trended toward poorer ratings for all HCAHPS subscales, reaching significance for the Communication about Medications subscale, with a mean score 1.2 (95% CI 0.48-1.76) points lower compared to non-homeless sample. Length of stay was not significantly different between homeless and non-homeless participants.
In an urban safety-net hospital, disparities in communications regarding medications between hospital staff and patients were found based on housing status.
