FFP3 masks were the most popular masks used for theatre activity whilst FFP2 and surgical masks were more widely used for examining patients and performing procedures in the emergency department. Changes in maxillofacial practice included the use of local flaps compared to free flaps, use of intermaxillary fixation (IMF) where appropriate for craniofacial trauma and routine COVID-19 testing for all inpatients.During the pandemic healthcare faced great pressure on the availability of protective equipment. This paper describes the entire novel innovative process of design optimisation, production and deployment of face-visors to NHS frontline workers during SARS-CoV-2 pandemic. The described innovative journey spans collaboration between clinicians and academic colleagues for design to the implementation with industry partners of a face-visor for use in a healthcare setting. It identifies the enablers and barriers to development along with the strategies employed to produce a certified reusable, adjustable, high volume and locally produced face-visor. The article also explores aspects of value, scalability, spread and sustainability all of which are essential features of innovation.The rapid spread of coronavirus disease 2019 (COVID-19) beginning in Spring 2020 necessitated significant changes to day-to-day interactions in society, as well as to the practice of medicine. Particularly in patients with cancer, these changes can exacerbate the pre-existing psychological stress associated with cancer diagnosis and treatment. We performed a narrative review, encompassing changes to cancer care as a result of COVID-19, the psychological effects of treatment delays, and strategies to mitigate these effects. A number of review articles and guideline bodies have provided guidance on patients for whom treatment may be safely delayed, including low-risk bladder, prostate and kidney tumors, as well as intermediate and high-risk prostate cancer. Mental health diagnoses are prevalent in patients with genitourinary malignancies. Evidence regarding psychologic effects of deferred treatment is limited to those with low risk of disease related morbidity. In this population, psychologic distress attenuated with time. However, in the COVID-19 context, patients with advanced disease are particularly prone to psychologic distress, as are women and younger patients. Strategies to mitigate this distress are emerging and center on recognition from the treating oncologist with appropriate referral as necessary to psycho-oncology providers and engagement of peer-supports. The COVID-19 pandemic has reshaped social structures and health care delivery. For patients with genitourinary malignancies, this may be associated with significant distress, particularly among those with advanced disease and those undergoing active treatment. Physicians treating these patients need to be aware of the psychologic stress the combined effects of the COVID-19 pandemic, cancer diagnosis, and cancer treatment can have and make appropriate referrals to support the holistic care of their patients.

The prompt identification of patients with poor prognosis is essential in order to improve the treatment outcomes in prostate cancer (CaP); as a novel approach, several molecular markers, including integrins, have been discussed as prognostic biomarkers. Our aim was to comprehensively examine aberrant expression of integrins in correlation with clinicopathological features and prognosis in CaP by synthesizing all available evidence, in a systematic review and meta-analysis.

A systematic review and meta-analysis was performed in accordance with the Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) guidelines. Scientific literature databases (Pubmed, Embase, and Scopus) were systematically searched until May 10, 2020. Random-effects (DerSimonian-Laird) models were used to estimate pooled odds ratios (ORs) for cross-sectional correlations with clinicopathological characteristics and relative risks for longitudinal associations with prognosis.

Fourteen studies were included with a total number of 3,194 CaP cases examined (13 cross-sectional and four longitudinal cohort study arms). Correlation of low expression of α

(pooled OR = 0.10, 95% confidence interval [CI] 0.04-0.28, P < 0.001) and β

(pooled OR = 0.45; 95% CI 0.21-1.00, P = 0.049) integrin with high Gleason score was noted. A borderline trend between reduced expression of α

integrin and an advanced clinical stage of CaP (pooled OR = 0.48; 95% CI 0.22-1.03, P = 0.06) was observed. No associations with biochemical recurrence and survival were documented.

Evidence on the association of low expression of integrins α

and β

and more advanced CaP exist, whereas significant results on survival were not documented; further studies are warranted.

Evidence on the association of low expression of integrins α6 and β1 and more advanced CaP exist, whereas significant results on survival were not documented; further studies are warranted.Advances in tissue engineering require the development of new biomaterials with adequate properties of cell attachment and growth. The properties of biomaterials can be improved by incorporation of bioactive molecules to enhance in vitro and/or in vivo functions. In this work, we study the role of a wheat germin-like protease inhibitor (GLPI), free or immobilized in biocompatible matrices to improve cell-attachment ability on different mammalian cell lines. The phylogenetic relationships and functional diversity of the GLPI were analyzed among diverse genera to get insights into sequence motif conservations. The cytocompatibility effect of free GLPI on C2C12 premyoblastic cells and B16 cells as tumoral model has been tested. GLPI promoted proliferation and metabolic activity of both cell types on in vitro models, not showing cytotoxic effects. Furthermore, GLPI was immobilized in chitin microparticles and in chitosan films; we demonstrated an accelerated cell adhesion process in both biomaterials.Chronic aortic regurgitation (AR) frequently leads to significant downstream changes to the left ventricle and pulmonary vasculature; these structural and physiologic changes result in lower- than expected patient survival. Progressive, uncorrected AR can lead to left ventricle dilation and subsequent mitral valve leaflet tethering, as well as mitral annular dilation, resulting in secondary mitral regurgitation (MR) in up to 45% of patients. Surgical aortic valve replacement (AVR) improves secondary MR in most patients, but survival is significantly lower in those patients who do not show improvement in MR after AVR. CAY10683 clinical trial Thus, there is considerable debate on whether the mitral valve should be intervened upon at the time of the AVR. In this review, the authors address the long-term outlook for patients with chronic AR and concurrent MR. The authors also review the available evidence on concomitant mitral valve surgery in patients undergoing AVR for AR. Lastly, this narrative review examines the recent advances in transcatheter mitral valve repair and replacement, and explores the potential role of transcatheter mitral therapies in patients with secondary MR due to AR.
