As more institutions incorporate in-house or outsourced 3D printing for research models and clinical care, ethical and regulatory concerns will become a greater consideration. This report highlights the uses of 3D printing in eye care by subspecialty and clinical modality, with an aim to provide a useful entry point for anyone seeking to engage with the technology in their area of interest.
Racial disparities have been well reported in the utilization and outcomes of knee arthroplasty, but it is unclear whether disparities also extend to the choice of surgical treatment. The primary objective of this study is to identify if race plays a role in the selection of unicondylar versus total knee arthroplasty (UKA, TKA) for isolated tibiofemoral osteoarthritis (OA). A secondary objective is to identify the differences in the complication rates for each procedure by racial identity.

A retrospective review of the 2006-2018 American College of Surgeons National Surgical Quality Improvement Program was performed. Asian, Black, Hawaiian/Pacific Islander, Hispanic, Native American/Alaskan, and White individuals who underwent primary elective UKA or TKA were compared in terms of UKA vs. TKA utilization rates and outcomes.

A total of 308,715 patients were analyzed. After controlling for all baseline differences, Whites (3.5%), Asians (3.7%), and Hawaiian/Pacific Islanders (3.1%) had around twice the rate of UKA compared to Blacks (1.6%), while Hispanics (2.1%) and Native American/Alaskans (1.7%) were in between (p <0.001). TKA was associated with higher complications compared to UKA in all racial groups (p < 0.001).

Minority patients, especially Blacks, were less likely to receive UKA for treatment of isolated knee OA. This is significant because treatment selection in patients who are eligible for UKA can have a significant impact on postoperative recovery and complications rates.

Patients with papillary thyroid carcinoma (PTC) enrolled from a single tertiary referral academic medical center were assigned to functional and visual identification of EBSLN group (study group) or no identification of EBSLN group (controlled group). The main outcome measures were the incidence of EBSLN injury detected by the intraoperative neuromonitoring and Voice Handicap Index-10 (VHI-10) and Impairment Index-5 (VII-5) valuation questionnaires. Postoperative complications were recorded. A total of 140 (50.4%) patients were enrolled in study group and 138 (49.6%) in controlled group. In the study group, 110 (39.3%) EBSLNs were direct visual recognized and 170 (60.7%) nerves were visually identified with the help of neuromonitoring. Three patients in the study group and two patients in the controlled group were diagnosed with vocal cord paralysis. Six (4.4%) patients in the identification group and 37 (27.2%) patients in the no identification group presented no response from the stimulation of sternothyroid-laryngeal triangle. The VII-5 scores of the study group were significantly higher than those of the controlled group at one and three months postoperatively (P = 0.024 and P = 0.034). With significant lower scores of VII-5 and VHI-10, functional and visual identification of EBSLN might be necessary during thyroid surgery to protect the structural integrity and motor activity of the nerve.COVID-19 is a disease caused by SARS-CoV-2 and was initially considered to cause serious damage to the respiratory system. Erastin2 inhibitor Over time, it has been found to affect other organs due to its ability to bind to the ACE2 receptor (type 2 angiotensin-converting enzyme), which can be found in various tissues, including the central nervous system. In addition, a large formation of pro-inflammatory cytokines responsible for various lesions was observed during the evolution of this disease. Our objective was to demonstrate the molecular mechanisms involved in the infection that may demonstrate the relationship between COVID-19 and the development of depressive conditions. Based on the main medical databases (LiLacs, SciELO, Bireme, Scopus, EBSCO, and PubMed) and using the terms 'coronavirus infections' AND 'Inflammation' AND 'depression' AND 'cytokines', we conducted an integrative review of articles published in 2020. Considering this stage of Covid-19 and the inflammatory component of depression, this review showed a relationship between these two conditions based on common pathophysiological mechanisms indicating possible depressive disorders in surviving patients, especially in the most severe cases. The role of inflammatory cytokines and the presence of ACE-2 receptors on the cell surface appear to be the common pathophysiological mechanism between COVID-19 and depression.Regenerative medicine promises a bright future where damaged body parts can be restored, rejuvenated, and replaced. The application of regenerative medicine is interdisciplinary and covers nearly all fields of medical sciences and molecular engineering. This review provides a road map on how regenerative medicine is applied on the levels of cell, tissue, and organ and summarizes the advantages and limitation of human pluripotent stem cells in disease modeling and regenerative application.
Nitrogen (N) is an essential macronutrient to maintain plant growth and development. Plants absorb nitrate-N or ammonium-N in the environment and undergo reduction reactions catalyzed by nitrate reductase (NR), nitrite reductase (NIR), glutamine synthetase (GS), and glutamine oxoglutarate aminotransferase (GOGAT) within plants.

A total of 42 N assimilation-related genes (NAG) members were identified in rapeseed. Darwin's evolutionary pressure analysis showed that rapeseed NAGs underwent purification selection. Cis-element analysis revealed differences in the transcriptional regulation of NAGs between Arabidopsis and rapeseed. Expression analyses revealed that NRs were expressed mainly in old leaves, NIRs were expressed mainly in old leaves and lower stem peels, while the expression situation between different subfamilies of GSs and GOGATs was more complicated.

Differential expression of NAGs suggested that they might be involved in abiotic stresses. The above results greatly enriched our understanding of NAGs' molecular characteristics and provided central gene resources for NAGs-mediated NUE improvement in rapeseed.

Despite their high similarity and shared interaction with many partners, CYFIP1 and CYFIP2 act at different points in cellular processes. CYFIP1 and CYFIP2 have different expression levels in human tissues, and knockout animals die at different time points of development. CYFIP1, similar to CYFIP2, acts in the WAVE regulatory complex (WRC) and plays a role in actin dynamics through the activation of the Arp2/3 complex and in a posttranscriptional regulatory complex with the fragile X mental retardation protein (FMRP). Previous reports have shown that CYFIP1 and CYFIP2 may play roles in posttranscriptional regulation in different ways. While CYFIP1 is involved in translation initiation via the 5'UTR, CYFIP2 may regulate mRNA expression via the 3'UTR. In addition, this CYFIP protein family is involved in neural development and maturation as well as in different neural disorders, such as intellectual disabilities, autistic spectrum disorders, and Alzheimer's disease. In this review, we map diverse studies regarding the functions, regulation, and implications of CYFIP proteins in a series of molecular pathways. We also highlight mutations and their structural effects both in functional studies and in neural diseases.
The composite metric textbook outcome (TO) has recently gained interest as a novel quality measure. However, the criteria for defining a TO have not been rigorously defined and patient perspectives on the characteristics of TO are unknown.

Patients who underwent major abdominal surgery at a single tertiary care center were administered a customized survey designed to ascertain their perspectives on defining TOs. The relationship between patient-reported and clinically defined TO rates was compared.

Among 79 patients who underwent gastrointestinal (51%), pancreatic (29%), hepatic (18%), or other major abdominal (3%) operations, 57% were female and 86% had an ASA class ≥3. Most patients underwent surgery for malignancy (87%) with 60% undergoing an open operation. Patients most commonly valued no mortality following surgery (96%), no reoperation (75%), and having a margin negative resection (73%) as "extremely important." In contrast, those outcomes that were most commonly valued as "not important at all" elineate these relationships and incorporate these factors to refine TO definitions.
In laparoscopic anatomic liver resection, an increasingly common procedure, the hepatic vein-guided approach is widely used although the hepatic vein tributaries can be a major source of bleeding in the event of inadvertent injury. This report describes the anatomy of the middle hepatic vein (MHV) including its tributaries based on reconstructed three-dimensional computed tomography images and provides anatomic data to enable safe middle hepatic vein-guided liver resection.

Following simulation modeling of the hepatic vasculatures, reconstructed MHV data was pooled from 35 healthy liver donors. Yields of the MHV tributaries were analyzed to enable MHV-guided liver resection.

A total of 252 tributaries were identified in the 35 donors. The MHV yielded fewer tributaries from its anterior and posterior aspects than from its right-side and left-side aspects (40 [15.9%], 13 [5.2%], 93 [36.9%], and 106 [42.1%], respectively). The MHV tributaries from the anterior and posterior aspects were smaller in diameterior or posterior aspect of the MHV should be accessed and exposed before the lateral aspects are dissected to minimize the risk of MHV tributary injury.
Burnout, or job-related stress, affects more than half of all US physicians, with primary care physicians (PCPs) experiencing some of the highest rates in medicine. Our study analyzes national survey data to identify and prioritize workplace climate predictors of burnout among PCPs within a large integrated health system.

Observational study of annual survey data from the Veterans Health Administration (VHA) All Employee Survey (AES) for 2013-2017. AES response rate ranged from 56 to 60% during the study period. Independent and dependent variables were measured from separate random samples. In total, 8,456 individual-level responses among PCPs at 110 VHA practice sites were aggregated at the facility level by reporting year. We used the semi-automated LASSO procedure to identify workplace climate measures that were more influential in predicting burnout and assessed relative importance using the Shapely value decomposition.
