Twelve tips for developing and implementing a medical education Twitter chat

Abstract

Live discussions on the social media site Twitter or Twitter chats are gaining popularity as powerful tools for engaging a broad audience in an interactive discussion. Medical education, in particular, is experiencing an increase in the use of this modality to support informal learning, as a means to encourage collaboration and share best practices, and as a platform for large-scale mentorship. Despite this growth in popularity, there are limited data to guide medical educators on the fundamentals of organizing a Twitter chat. In this Twelve Tips article, we discuss strategies relevant to potential Twitter chat organizers. We have arranged the tips chronologically, beginning with a discussion of initial considerations when planning and formulating a chat topic and publicizing the chat to potentially interested people and groups, followed by practical considerations while hosting the chat, and finally strategies for evaluating and extending a Twitter chat’s impact.     

COVID-19 pandemic,as experienced in the surgical service of a district hospital in Spain

The coronavirus disease 2019, which is caused by severe acute respiratory syndrome coronavirus 2, was first identified in December 2019 in Wuhan, China, and has since spread rapidly, evolving into a full-blown pandemic. We would like to report our experience after 1 year of this pandemic in the surgical service of a district hospital in Spain. There have been many changes (including new protocols) that our service and the hospital have undergone, to adapt to the new situation. We believe that this experience can be useful for other professionals who have lived and are living a similar situation.     

Renal Neoplasia in Tuberous Sclerosis: A Study of 41 Patients

ObjectiveTo study the clinical features and identify unique renal neoplasia subtypes and their prognostic implications in individuals with tuberous sclerosis complex (TSC).Patients and MethodsThe Mayo Clinic nephrectomy registry included 37 patients with TSC diagnosed between 1970 and 2018. Four additional patients were identified from the pathology consultation and autopsy files. All available renal tumors were further characterized using immunohistochemistry and fluorescence in situ hybridization. Clinicopathologic features and follow-up were obtained from the medical record. The American Association for Cancer Research Project GENIE registry was accessed using cBioPortal for molecular profiling of angiomyolipoma (AML).ResultsA total of 276 renal tumors from 41 patients were analyzed. Renal tumors were classified into 9 distinct morphological subtypes, with AML predominating (238 [86%]). Interestingly, all these tumors acted in a benign fashion except one renal cell carcinoma with clear cells and fibromyomatous stroma and one epithelioid AML that metastasized. Molecular profiling studies revealed that epithelioid AMLs were enriched for alterations of TP53, RB1, and ATRX. Eight patients died of direct complications of TSC, including 3 of end-stage renal disease. To date, none have died of a renal epithelial neoplasm.ConclusionThe identification of unique renal neoplasia subtypes may provide important clues to establish a diagnosis of TSC, and in the somatic setting, this finding has important implications for accurate prognostication. These tumors tend to be indolent, and only 2 of 276 tumors in our study exhibited metastatic behavior. Our results support multidisciplinary management with a focus on preservation of renal function.     

Polymer Grafted Nanoparticle Viscosity Modifiers

It is demonstrated that the addition of nanoparticles can decrease the viscosity of an entangled polymer matrix (plasticization). While there has been considerable effort in understanding the role of bare nanoparticles on viscosity, the corresponding study on grafted particles is nascent. Two nanometer radius zirconia fillers with a bimodal population of grafted PDMS is used. Two fillers are considered: one has grafted chains with a molecular weight, M_g, less than the entanglement M, M_g < M_e (ZrO₂ 1k 10k), and the other filler has grafted chains M > M_c (the critical M_e) (ZrO₂ 1k 36k). The ZrO₂ 1k 10k composites exhibit plasticization for large matrix molecular weight M_m. The ZrO₂ 1k 36k composites, in contrast, have Einstein‐like behavior. The plasticization effects are either due to: the small filler size relative to the tube diameter or an increase in chain mobility at the interface due to autophobic dewetting.     

Solitary calvarial plasmacytoma.

One patient with a solitary plasmacytoma of the frontal bone was treated with complete surgical resection. To reconstruct the large calvarial defect, a split-thickness calvarial graft was harvested from the parietal area and secured in place with miniplates. Solitary plasmacytomas of the calvaria are not common. Clinical presentation, diagnostic criteria, therapeutic approaches, and prognosis are discussed.     

The Integration of Studio Cycling into a Worksite Stress Management Programme

High stress is a prevalent problem in the worksite. To reduce stress, improve productivity, reduce absenteeism, and lower healthcare costs, many companies offer exercise classes or stress management programmes. Although physical activity is an important component of stress management, few worksites have integrated physical activity into their comprehensive stress reduction programmes. The purpose of this single‐arm pilot project was to examine the potential effectiveness of an integrated exercise (studio cycling) and cognitive–behavioural stress management programme. Eighty‐four adults, 75% female, mostly aged 40+ years, participated in an integrated 12‐week cycling studio and cognitive–behavioural stress management programme. Participants experienced a significant and clinically meaningful reduction on the Perceived Stress Scale (p < 0.01), rating of current stress level and confidence to manage stress at the programme's end and at a 1‐month follow‐up. Participants also reported having significantly improved overall health, improved nutritional habits, higher physical activity level, greater confidence in their ability to follow a healthy diet, higher spiritual well‐being, improved sleep, receiving more support for maintaining healthy living and improved quality of life at the completion of the 12‐week programme and 1‐month follow‐up. These findings provide further support for an integrated exercise and stress management programme. Copyright © 2013 John Wiley & Sons, Ltd.
