9%. Systolic hypotension >20 min was associated with AKI (OR, 3.88; 95% CI 1.38-10.9), which was not significant after adjusting for vasopressors, creatinine, American Society of Anesthesiologists class, and hemoglobin drop. The cumulative dose of any specific vasopressor >20 mg (or >10 mg epinephrine) was independently associated with AKI (adjusted OR, 2.47; 95% CI 1.34-4.58). Every 5 mg increase in the total dose of all intraoperative vasopressors used during surgery was associated with 11% increased odds of AKI (95% CI 3-19%).

High vasopressor use was associated with postoperative AKI in elderly patients undergoing noncardiac surgery, independent of hypotension identified from anesthetic charts.

In this study, the interaction of these phytochemicals CHN/CHG, with the two major transport proteins for various drugs, human serum albumin (HSA) and α-1-acid glycoprotein (AGP), was unraveled by using several spectroscopic techniques and computational methods. The binding of CHN/CHG quenches the HSA/AGP fluorescence intensities, and also these phytochemicals are bound strongly to HSA/AGP proteins. An apparent decrease in fluorescence intensities of CHN/CHG-HSA and CHN/CHG-AGP complex showed the static mode of fluorescence quenching. Furthermore, the intrinsic fluorescence and using site-specific markers ibuprofen competing with these molecules, thereby replacing it in the binding site of subdomain IIIA. The computational methods substantiated the experimental findings, revealing that CHN interacted with Lys414A, Glu492A, Glu492A and Lys413A residues of subdomain IIIA of HSA and for CHG showed the interaction with Lys545A and Lys413A residues of subdomain IIIA of HSA. Fluorescence and surface plasmon resonance data unveiled a previously unreported binding event between CHN/CHG and HSA; the determined binding affinities of both compounds were slightly higher for HSA than AGP. A change in functionality of protein confirmed the esterase-like activity of HSA in the presence of CHG/CHN upon binding with CHG/CHN. Displacement and circular dichroism (CD) experiments analysis showed that the two CHN/CHG and binding specifically to IIIA subdomain on HSA results in the conformational changes in the HSA. Thus, CD revealed a few conformational changes in HSA due to CHN/CHG. The binding of these two phytochemicals to the plasma proteins would give a path to develop new inspired drug molecules for chronic diseases.Communicated by Ramaswamy H. Sarma.

To perform a retrospective characterization of one-star reviews of ophthalmologists on Yelp.com and to increase understanding of patient complaints on Yelp.com.

A search was performed for reviews on Yelp.com using the keyword "ophthalmologist" for the top 8 most population-dense metropolitan areas in the United States. One-star reviews were collected and classified as procedural or nonprocedural. Complaints were also categorized as clinical, nonclinical, or both. Clinical complaints cited issues such as complications, reoperations, uncontrolled pain, misdiagnosis, unclear treatment plan, etc. Nonclinical complaints included comments such as physician bedside manner, other staff interpersonal manner, wait time, brevity of appointment time, etc.

5,532 total reviews were assessed, of which 477 (9%) one-star reviews were included in the study for analysis. These reviews amounted to 1,120 distinct complaints. 287 (26%) were clinical in nature and 833 (74%) were nonclinical. Technical incompetence or error (5on and retention, the characterization of excessively negative reviews allows identification of potential areas of concern for patients that use online review sites such as Yelp.com.

The majority of one-star reviews of ophthalmologists included in this study were nonclinical. Complaints referencing a procedural episode were more likely to include a clinical component in the review. In the era of intense medical consumerism and increased physician and health care institution competition for patient acquisition and retention, the characterization of excessively negative reviews allows identification of potential areas of concern for patients that use online review sites such as Yelp.com.Nanoparticles (range under 100 nm) prepared by different technology modes including physical, chemical, biological have many applications. Like in the same way silver nanoparticles are used for different beneficial actions like antimicrobial- antibacterial, antifungal and antiviral, anti-inflammatory, anticancer, water treatment, cosmetics, and in the textiles industry. As silver nanoparticles have shown wide application by different mechanisms against various pathophyisiological conditions. To maintain safety under their use, the study of the toxicity of silver nanoparticles has become more important. Health agencies like WHO, NIOSH, EPA, EFSA & EU have issued guidelines for unrisky exposure limit of silver nanopartricles in drinking water, food and breathing. The main purpose of this article is to summarize genotoxicity, cytotoxicity, neurotoxicity, reproductive toxicity of silver nanoparticles in both in vitro and in vivo studies focused on mechanism and methods of detection. The main mechanism of silver nanoparticles toxicity involves disruption of the mitochondrial respiratory chain, which results in the generation of ROS and the stoppage of ATP synthesis which further leads to a cascade of toxic events. A-196 ROS production measured by the technique like flow cytometry using DCFHDA dye and other method includes a confocal microscope, lipid peroxidation, etc. Different assay techniques used for evaluation of different kind of toxicities such as the comet assay, MTT assay, and histological assay, are also discussed.Background Monocrotophos (MCP) is an organophosphate pesticide with well-known toxicity in mammals. Exposure of MCP is associated with altered molecular physiology at sub-cellular levels. This study investigated the efficacy of N-acetylcysteine (NAC) against MCP exposure mediated mitochondrial dysfunctions in hepatic tissue of rats.Methods Male Wistar rats were given NAC (200 mg/kg b.wt), MCP (0.9 mg/kg b.wt) and NAC together with MCP, intragastrically for 28 consecutive days. Mitochondrial complexes activities were evaluated using biochemical analysis. mRNA expression of mitochondrial complexes subunits, PGC-1α and its downstream regulators were analyzed using polymerase chain reaction.Results Exposure of MCP (0.9 mg/kg b.wt, intragastrically, 28 d) decreased mitochondrial complexes activities and gene expression of complexes subunits. The expression of PGC-1α, NRF-1, NRF-2, and Tfam was also reduced significantly. The administration of NAC (200 mg/kg b.wt, intragastrically, 28 d) significantly increased mitochondrial complexes activities and gene expression of complexes subunits. Additionally, NAC also maintained mitochondrial functions, and enhanced the gene expression of PGC-1α and its downstream regulators.Conclusion The results of this study indicate that NAC prevents hepatic mitochondrial dysfunctions and maintains PGC-1α signaling. In conclusion, NAC might be speculated as a therapeutic agent for mitochondrial dysfunctions following toxic exposures.Interprofessional education (IPE) programs, are complex, logistically challenging, and can be expensive to deliver, but these matters are offset by the perceived benefits of IPE. There is little clarity regarding how IPE contributes to the desirable development of collaborative practitioners. To guide educators in the design of IPE programs there is a need to understand the elements that promote optimal learning. A realist review was conducted to identify the mechanisms and resources that contribute to IPE outcomes. Four databases were searched until April 2020 for empirical studies describing mandatory IPE for pre-registration medical, nursing and other health professional students. Twelve articles met the inclusion criteria. Two novel learning design elements were identified; interdependence, where there is a need for genuine contribution of skills and knowledge from the professions learning together to successfully complete tasks, and embodiment, where through being immersed in an authentic scenario, learners feel what it is like to work in their professions. Other observations supported previous research findings such as the importance of skilled facilitators to promote interaction and reflection. Interprofessional interventions incorporating these specific learning design features seem likely to enhance the impact of IPE, thus making the best use of limited institutional resources and student time.The importance of interprofessional collaborative practice has come into focus over the past decade as coordination and delivery of health care becomes increasingly complex. The need for students to acquire collaboration-building skills to prepare them to work effectively within diverse healthcare teams to improve patient outcomes is a goal of interprofessional education (IPE). Accrediting bodies across healthcare professions require IPE as part of a robust curriculum to build collaborative skill sets and create a practice ready workforce. To respond to this need, an online healthcare program developed an innovative model for student collaboration across professions and institutions through a virtual interprofessional education (VIPE) program. The VIPE model aims to simulate clinical practice via an asynchronous and synchronous pedagogical approach that combines PBL/CBL with psychological safety. VIPE demonstrated statistically significant gains in knowledge and positive attitudes toward interprofessional collaborative practice as a result of participation in the VIPE program. During COVID-19, the demand for high quality IPE for health professions' students in virtual settings has grown, VIPE has the potential to be a solution for this. VIPE requires a dedicated committee and technical lead. Further research could involve longitudinal studies and nonaggregate models.Inflammatory myofibroblastic tumor (IMT) infrequently involves the sigmoid colon, and has not previously been described in an infant sigmoid colon.An inflammatory myofibroblastic tumor arose from the sigmoid colon of an 11-month-old boy, confirmed by anaplastic lymphoma kinase (ALK), smooth muscle actin (SMA) and desmin immunohistochemical staining. The patient recovered well after complete resection of the tumor.Sigmoid IMT can occur in infancy. This eighth case is the youngest so far. The child did well after surgical resection.

To investigate how urological studies using composite endpoints as the primary outcome were cited.

In this quality analysis of citations, three randomized clinical trials each investigating oncological and non-oncological urology were selected for citation analysis based on pre-defined criteria. In total, 531 papers citing the selected studies were reviewed; citations were evaluated based on whether they correctly referred to the composite endpoint and if singleton endpoints were defined and/or discussed.

Among the citations, 223/531 (42%) referred to the composite endpoint, of which 217/223 (97.3%) correctly cited the composite endpoint. However, only 91/217 (41.9%) defined and/or discussed the singleton endpoints of the composite endpoint. The lack of a validated instrument for citation analysis was a limitation of this study. Meanwhile, the main strength is the large number of individually analyzed citations.

The composite endpoints of urological randomized clinical trials are generally cited without referring to the composite endpoint; when cited, the composite endpoints are described correctly.
