The purpose of this paper is centred on the kinetics of removal of main pollutants in wastewater and to compared different hydraulic loading conditions of the constructed rapid infiltration system (CRI system) in terms of removal efficiencies, effluent concentrations, mass removal rate (MRR), and the first-order removal rate coefficient (k) of COD, TOC, NH4+-N, TN, and TP. The results showed that the higher the hydraulic loading, the higher the effluent concentration. The results that synthesized hydraulic loading, effluent concentrations, removal efficiencies, and other conditions showed that the best hydraulic loading was 40 cm/d. When the hydraulic load was 40 cm/d, the effluent average concentrations of COD, TOC, NH4+-N, TN, TP, Cu2+ and the removal efficiencies were 27.31 ± 16.40 mg/L, 86.11%, 10.55 ± 5.25 mg/L, 84.64%, 0.59 ± 0.87 mg/L, 99.60%, 143.31 ± 14.77 mg/L, 7.04%, 5.64 ± 1.38 mg/L, 79.20%, and 0.13 ± 0.47 mg/L, 97.51%, respectively. According to a kinetic study of the primary pollutants, the MRR increased with an increase in the hydraulic loading, except for ammonia nitrogen. CRI-3, CRI-4 were high significant correlated with ammonia nitrogen (with R2 = 93.65% and R2 = 95.03%, respectively), while CRI-2, CRI-3, and CRI-4 were high significant correlated with total nitrogen (with R2 = 94.56%, R2 = 96.70% and R2 = 96.56% respectively).Social media is a common, multi-purpose tool used by most hospitals to engage a broad audience. The relationship between hospital social media activity and performance on influential reputation and patient experience ratings is not well described. The aim of this study was to characterize social media activity across the top 100 revenue grossing U.S. hospitals and its impact on key patient experience and hospital rankings. While nearly all top 100 revenue grossing U.S. hospitals have a presence on social media, usage and following significantly varied. Social media activity metrics collected showed some limited association with reputation and patient experience-influenced rankings.Feedback has been shown to be one of the most powerful and effective influences on student achievement; however, the optimal method for providing feedback to trainees during veterinary skills training has yet to be determined. A prospective mixed-methods study was undertaken to evaluate student perceptions and performance outcomes with self-assessment using video- or instructor-delivered feedback during skills training using a model. Forty participants naïve to intravenous (IV) catheter placement were randomly assigned either to self-assessment using video or to instructor-directed feedback. A questionnaire probing participants' perceptions of their knowledge level and confidence in their skills was completed before and after the training, and an interview was done at study completion. Final skill performance was recorded using video capture to permit blind evaluations using a standard assessment tool. A quantitative evaluation of the performance and questionnaire scores, as well as a qualitative assessment of the interviews, was performed. Questionnaire scores were significantly higher in the post-study questionnaire for 12 of the 14 questions in both groups. Students assigned to the instructor-directed group had significantly higher scores than students in the self-directed group on the skill performance (p less then .05). Self-reported confidence in knowledge and skill related to the IV catheterization technique improved with both self-directed feedback using video and instructor-directed feedback. Skill performance, however, was superior following instructor-directed feedback. Participants expressed positive experiences associated with use of the models for skills training, the value of the learning materials including the video, and guidance during learning.

Presence of comorbid diseases at time of cancer diagnosis may affect prognosis. We evaluated the impact of comorbidity on survival of patients diagnosed with renal cell carcinoma (RCC), overall and among younger (<70 years) and older (≥70 years) patients.

We established a nationwide register-based cohort of 7894 patients aged ≥18 years diagnosed with RCC in Denmark between 2006 and 2017. We computed 1- and 5-year overall survival and hazard ratios (HRs) for death according to the Charlson Comorbidity Index (CCI) score.

Survival decreased with increasing CCI score despite an overall increase in survival over time. The 5-year survival rate of patients with no comorbidity increased from 57% among those diagnosed in 2006-2008 to 69% among those diagnosed in 2012-2014. During the same periods, the survival rate increased from 46% to 62% among patients with a CCI score of 1-2 and from 39% to 44% for those with a CCI score of ≥3. Patients with CCI scores of 1-2 and ≥3 had higher mortality rates than patients with no registered comorbidity (HR 1.15, 95% CI 1.06-1.24 and HR 1.56, 95% CI 1.40-1.73). Patterns were similar for older and younger patients. Particularly, diagnoses of liver disease (HR 2.09, 95% CI 1.53-2.84 and HR 4.01, 95% CI 2.44-6.56) and dementia (HR 2.16, 95% CI 1.34-3.48) increased mortality.

Comorbidity decreased the survival of patients with RCC, irrespective of age, despite an overall increasing survival over time. These results highlight the importance of focusing on comorbidity in this group of patients.

Firstly, the analytical solutions for the pore fluid pressure and velocity in the idealized cartilage defect model were obtained, which are employed to validate the finite element (FE) method. Then according to the MRI data, an articular cartilage FE model was developed to study the effects of defect characteristics on its poroelastic behaviors. The results showed the interstitial fluid pressure and velocity in defected articular cartilage is diminished, moreover, this trend is even more severe as the defect radius or thickness increased. As the development of osteoarthritis goes, the fluid velocity is decreased and cause the even serious nutrients loss.

The possible association between history of pulmonary tuberculosis (TB) and lung cancer (LC) has attracted researchers' attention for several decades. EG-011 This systematic review and meta-analysis aim to assess the association between previous pulmonary TB infection and LC risk.

A Systematic and comprehensive search was performed in the following databases PubMed, Embase, clinical key, Web of Science and Google Scholar, in articles and abstracts published from 1987 to 2021. Thirty-two articles (involving 50,290 cases and 846,666 controls) met the inconclusive criteria. The Comprehensive Meta-Analysis version 2.2 software was used for this meta-analysis.

The result of this meta-analysis demonstrates that pre-existing active pulmonary TB increases the risk of LC (RR = 2.170, 95% confidence interval [CI] 1.833-2.569,

 < .001,



= 91.234%). The results showed that the risk of the history of active pulmonary TB infection in adenocarcinoma was 2.605 (95% CI 1.706-3.979,

 < .001,



= 55.583%), in small-cell carcinoma was 2.118 (95% CI 1.544-2.905,

 < .001,



= 0.0%), in squamous-cell carcinoma, was 3.570 (95% CI 2.661 - 4.791,

 < .001,



= 42.695%) and 2.746 (95% CI 2.300-3.279,

 < .001,



= 41.686%) for other histological types of LCs. According to these results, a history of active pulmonary TB increases the risk of LC.

This study emphasizes the importance of LC screening in pulmonary TB patients even after the infection is treated. With the increased chances of LC in a patient who had a history of active pulmonary TB, there could be a need for a further follow-up period after pulmonary TB recovery.

Visual art has been increasingly incorporated into medical education and has been shown to enhance important competencies, such as empathy. However, limited evidence on effective visual art program design and evaluation processes remain. This systematic review examines the format, content, and espoused outcomes of visual art-based training programs in undergraduate medical education.

A comprehensive literature search of MEDLINE, EMBASE, the Cochrane Central Register of Controlled Trials, and ProQuestERIC on undergraduate medical education and visual arts retrieved 1703 articles published from 2014 to 2020. After reviewing inclusion and exclusion criteria, 23 articles were chosen for full review and synthesis.

Program format and content varied, ranging from 1-day specific competency focused programs to well-structured comprehensive 6-12-week programs. 6 areas of program foci were identified observation skills, empathy, tolerance to uncertainty, cultural sensitivity, team building and collaboration, and wthe strongest evidence of its effectiveness compared to the other competencies. Future programs incorporating visual arts will benefit from a longitudinal (greater than 6 weeks) program which incorporates guided artworks, reflection exercises, and a group discussion to provide a stronger foundation for the development of core competencies. We propose using validated scales to measure outcomes in future studies and follow-up with participants to better assess Kirkpatrick Level 3 and 4 outcomes.There is heterogeneity across studies and a lack of knowledge about recovery of EFs over time following traumatic brain injury (TBI). Also, EFs are associated with functional outcome, but there is still a gap in knowledge concerning the association between EFs and social participation following TBI. For this reason, we aim to (1) measure the recovery of the three executive function subcomponents of Miyake's model, namely flexibility, updating and inhibition between the acute phase (T1) and 6 months post TBI (T2) and (2) measure the relationship between EFs and social participation after TBI. Thus, a prospective longitudinal study that included 75 patients with TBI (mild and moderate-severe) and 50 patients with orthopedic injuries (controls) without brain damage was carried out. An extensive EFs test battery was administered at T1 and T2 whereas the Mayo-Portland Adaptability Inventory-4 (MPAI-4) was administered only at T2. In contrast with the controls, both TBI groups improved significantly between T1 and T2 on WMS-III Mental Control test (MC) and the D-KEFS Category Switching Condition of the Verbal Fluency task (SVF). Results also showed a simple time effect for the WAIS-IV Digit span and the Hayling tests. Moreover, there was an association between the SVF test and social participation (MPAI-4) at T2. In conclusion, the MC and SVF tests were found to be the best tools for measuring recovery of EFs following TBI. The SVF test was the most likely measure of EFs to give the neuropsychologist an idea of the patient's social participation.
