On December 18, 2019, the FDA granted accelerated approval to enfortumab vedotin-ejfv (PADCEV; Astellas and Seattle Genetics) for treatment of patients with locally advanced or metastatic urothelial cancer who have previously received a programmed cell death protein 1 or programmed death ligand 1 inhibitor, and a platinum-containing chemotherapy in the neoadjuvant/adjuvant, locally advanced or metastatic setting. Substantial evidence of effectiveness for this application is obtained from Cohort 1 of the single-arm, multicenter Study EV-201. Patients received enfortumab vedotin (EV) 1.25 mg/kg (up to a maximum dose of 125 mg) intravenously on days 1, 8, and 15 of 28-day cycles until disease progression or unacceptable toxicity. Confirmed objective response rate in the 125-patient efficacy population determined by blinded independent central review was 44% [95% confidence interval (CI), 35.1-53.2], with complete responses in 12%. Median response duration was 7.6 months (95% CI, 6.3-not estimable). Grade 3-4 adverse reactions occurred in 73% of patients. Hyperglycemia, peripheral neuropathy, ocular disorders, skin reactions, infusion site extravasations, and embryo-fetal toxicity are labeled as warnings and precautions for EV. The article summarizes the data and the FDA thought process supporting accelerated approval of EV. This approval may be contingent upon verification and description of clinical benefit in confirmatory trial(s).
Some evidence suggests the association between body mass index (BMI) and pancreatic cancer risk is weaker among current smokers than among never smokers.

We examined the association between BMI and pancreatic cancer mortality among adults who reported smoking status at enrollment into Cancer Prevention Study-II in 1982, including 420,543 never smokers, 282,244 former cigarette smokers, and 219,885 current cigarette smokers. After excluding the first 3 years of follow-up to reduce reverse causation, we calculated multivariable-adjusted hazard ratios (HR).

During the full follow-up period from 1985 to 2014, 7,904 participants died of pancreatic cancer. The HR per 5 BMI units was lower among current smokers [HR = 1.14; 95% confidence interval (CI), 1.07-1.20] than never smokers (HR = 1.22; 95% CI, 1.17-1.27), although this difference was not statistically significant (
= 0.06). BMI was significantly less strongly associated with pancreatic cancer mortality among current smokers reporting ≥20 cigarettes/day (HR = 1.10; 95% CI, 1.03-1.18) than among never smokers. During follow-up within 10 years of enrollment, when current smokers at enrollment were the most likely to have still been smoking, BMI was not associated with pancreatic cancer mortality among current smokers (HR = 1.02; 95% CI, 0.90-1.16,
= 0.03 for difference between current and never smokers). BMI HRs were similar among former and never smokers.

These results support a weaker association between BMI and pancreatic cancer among current smokers than among never smokers.

In populations with low smoking prevalence, the pancreatic cancer burden due to BMI is likely to be higher than that predicted by risk estimates from studies including substantial numbers of smokers.

Certain groups are known to be at higher risk of contracting severe COVID-19 infection, such as men and people from Black, Asian and minority ethnic (BAME) backgrounds. Identifying and managing HCWs who have been exposed to COVID-19 is of utmost importance in preventing healthcare transmission and protecting staff and vulnerable patients in healthcare settings. Recently, antibody testing to diagnose previous COVID-19 exposure among HCW has commenced in the UK. This provided an opportunity to assess exposure to COVID-19 among the various subgroups within the HCW community, based on their roles and ethnic background. We found that HCWs working in patient-facing roles were twice as likely to have been exposed to COVID-19 than their colleagues in non-patient-facing roles. Reassuringly, workers from BAME backgrounds had a similar risk of previous COVID-19 exposure to their white colleagues. More research is required to assess how frontline staff, especially those working in patient facing roles, can reduce their risk of exposure to COVID-19.
COVID-19 has had a profound effect on the NHS. Little information has been published as to how the unselected medical take has been affected.

We retrospectively reviewed patients who were referred to general medicine during March 2020. We compared clinical outcomes of patients with and without COVID-19.

814 patients were included, comprising 777 unique patients. On average, 26 patients were admitted per day. 38% of admitted patients were suspected of COVID-19, with greater numbers of COVID-19 patients in the second half compared to the first half of the month (p<0.001). Logistic regression analyses showed suspected COVID-19 was an independent predictor for inpatient mortality (odds ratio [OR] = 6.09, p<0.001) and 30-day mortality (OR = 4.66, p<0.001).

COVID-19 patients had worse clinical outcomes and increased healthcare use compared to non-COVID-19 patients. Our study highlights some of the challenges in healthcare provision faced during this pandemic.

To describe the development and initial evaluation of a brief e-learning course as a means of teaching shared decision making and risk communication skills to clinicians of all specialties.

Comparison pre-course and post-course of scores in subjective confidence and objective knowledge about shared decision making and risk communication.

Online and open to all specialties and levels of clinical experience, including students.

The course is freely available online and all who started the course from September 2018 to May 2020 were invited to participate in the evaluation study.

The self-guided e-learning course is made up of four modules and takes approximately 2 hours to complete. It is hosted on the website of the Winton Centre for Risk Communication and the UK's National Health Service e-learning platform.

Pre-course and post-course confidence in performing shared decision making (as measured by a 10-item scale adapted from the OPTION tool; total score range 10-50), and objective knowledge aboutExclusivity in physical spaces and nutrients is a prerequisite for survival of organisms, but a few species have been able to develop mutually beneficial strategies that allow them to co-habit. Here, we discovered a mutualistic mechanism between filamentous fungus, Aspergillus nidulans, and bacterium, Bacillus subtilis The bacterial cells co-cultured with the fungus traveled along mycelia using their flagella and dispersed farther with the expansion of fungal colony, indicating that the fungal mycelia supply space for bacteria to migrate, disperse, and proliferate. Transcriptomic, genetic, molecular mass, and imaging analyses demonstrated that the bacteria reached the mycelial edge and supplied thiamine to the growing hyphae, which led to a promotion of hyphal growth. The thiamine transfer from bacteria to the thiamine non-auxotrophic fungus was directly demonstrated by stable isotope labeling. The simultaneous spatial and metabolic interactions demonstrated in this study reveal a mutualism that facilitates the communicating fungal and bacterial species to obtain an environmental niche and nutrient, respectively.
Hybrid positron emission tomography (PET) and magnetic resonance (MR) imaging is an emerging technology in the diagnosis of cardiovascular disease; however, there have been no reports of its use in the national clinical setting. Our objective was to evaluate the additional value of integrated PET/MR systems compared with MR and PET performed separately in this setting.

We prospectively included 49 patients, 30 to assess myocardial viability (coronary group) and 19 to assess inflammatory, infectious, and tumoral diseases (noncoronary heart disease group). All patients underwent cardiac
F-fluorodeoxyglucose PET/MR. PET/MR studies included attenuation correction sequences, followed by simultaneous cardiac PET and cardiac MR acquisition, with protocols adapted to the clinical indication (cine, tissue characterization and/or late enhancement imaging).

Most (87.8%) PET/MR studies were initially interpretable. Use of PET/MR improved diagnosis vs PET or MR performed separately in 42.1% of coronary cases and 8de the possibility of simultaneous acquisition, the in vivo integration of anatomical/functional/metabolic aspects, and the interaction of different experts in imaging modalities.The University of Toronto launched a longitudinal integrated clerkship (LIC) pilot project in 2014. Our aim was to evaluate LIC student outcomes in obstetrics and gynaecology compared with those of traditional block students. LIC and block students underwent identical evaluations, including written and oral exams, as well as clinical assessments from the ward. LIC student scores in each domain were compared with those of the traditional block students over 4 years. There were no differences in overall pass/fail status between LIC and block students. Thus, our LIC design could be appropriately modeled at other teaching institutions contemplating introducing an LIC stream.
There are few data concerning patients with Crohn's disease (CD) complicated by a stricture of the upper gastrointestinal tract (UGT).

We evaluated the outcome and management of CD patients complicated by a stricture of the UGT.

We performed a retrospective multicenter study including all CD patients with a non-passable symptomatic UGT stricture on endoscopy. Primary outcome measure was surgery-free survival from diagnosis of stricture. Efficacy of medical, endoscopic, and surgical treatments, and identification of predictors of surgery were also evaluated.

60 CD patients with an UGT stricture were included. 60% of the strictures were located in the duodenum. With a median follow-up of 5.5 (IQR 3.0-12.0) years since stricture diagnosis, surgical-free survival was 75% and 64% at 1 and 5 years, respectively. At the end of the follow up, 27 (45%) patients underwent surgery. 77 endoscopic procedures were performed in 30 patients with an immediate success of 81% and a clinical benefit in 84% of the procedures. In multivariate analysis, anti-TNF treatment initiation was associated with a reduced risk of surgery.

CD UGT strictures are mainly located in the duodenum. PP121 chemical structure Medical and endoscopic treatments allow to avoid surgery in half of the patients.
