8 mm (range, 6.0-24.0 mm), and the mean distance from the nearest pleural surface was 13.4 mm (range, 2.5-34.9 mm). After the ENB-guided localisation procedure was completed, the dye was visualised in 23 nodules (82.1%) using VATS. The average duration of the ENB-guided pleural dye marking procedure was 12.6 min (range, 4-30 min). The resection margins were negative in all malignant nodules. Complications unrelated to the ENB-guided localisation procedure occurred in two patients, including one case of haemorrhage and one case of slow intraoperative heart rate. CONCLUSION ENB can be used to safely and accurately locate small peripheral pulmonary nodules and guide surgical resection.

Published by BMJ.BACKGROUND The first-line treatments for mild-moderate and moderate-severe depression according to the National Institute for Health and Care Excellence clinical guidelines for the management of depression in adults are psychological therapies followed by or alongside pharmacological treatment. We conducted an audit of patient records (as recorded by general practitioners (GPs)) to compare practice to the guidelines. METHODS Incident cases were retrospectively identified from electronic primary care records (SystmOne). From 40 320 registered patients, cases were identified based on previously coded new diagnoses of depression in the 2016-2017 and 2017-2018 Quality and Outcomes Framework (QOF) years. Patient notes were screened for exclusion criteria (mental health problems that would alter management pathway) and for records of management discussions (pharmacological or psychological therapies) at the diagnostic appointment. RESULTS In 2016-2017 (n=315), psychological therapies for depression were discussed at 63.2% of diagnostic appointments, they were most discussed at appointments with those aged 18-29 years (70.8%), but this decreased with age to 56.3% of appointments with those aged ≥65 years. In 2017-2018 (n=244), psychological therapies were discussed at 70.9% of diagnostic appointments but were discussed at more appointments with those aged 18-29 years (81.6%) and at less appointments with those aged ≥65 years (39.4%). Discussion of pharmacological management was similar for all age groups in 2016-2017 (89.9%) and 2017-2018 (93.0%). IMPLICATIONS For patients aged ≥65 years, psychological therapies are featuring less in management discussions with GPs or are not being recorded. Recommendations for change implemented at the practice included feedback of results and professional reminders throughout the 2019-2020 QOF year. © Author(s) (or their employer(s)) 2020.

Published by BMJ.BACKGROUND Residents in internal medicine programmes lack formal training in leadership, curriculum development and clinical teaching. Residency programmes created clinician-educator tracks (CETs) to formally teach residents to become effective educators and to involve them in the science of medical education. However, the curricula in these tracks are often locally developed and remain at the discretion of the individual programmes. METHODS This survey evaluates the frequency of CETs in internal medicine residency programmes in the USA and descriptively analyses their logistical and curricular content. During the academic year 2017-2018, directors of all Accreditation Council for Graduate Medical Education (ACGME) accredited internal medicine residency programmes in the USA were invited to participate in this survey (n=420). We developed a web-based 22-question survey to assess the logistics and curricular content of CET programmes. RESULTS A total of 150 programmes responded to the survey invitation (response rate=35.7%). Only 24% (n=36) of programmes offered a CET, the majority of which have been available for only 5 years or less. The track is most frequently offered to postgraduate year (PGY)-2 and PGY-3 residents. Only a minority of participating faculty (27.8%) have protected time to fulfil their CET role. Bedside teaching, feedback, small group teaching and curriculum development are the most commonly taught topics, and faculty mentorship and small group teaching methods are the most commonly used types of instruction. Atglistatin in vivo CONCLUSIONS CETs are offered in only 24% of internal medicine residency programmes in the USA. The curricula of these tracks vary across programmes, and their success is often countered by logistic and financial challenges. © Author(s) (or their employer(s)) 2020. No commercial re-use.

Published by BMJ.CD40 plays an important role in immune responses by activating the JNK and NF-κB pathways; however, the precise mechanisms governing the spatiotemporal activation of these two signaling pathways are not fully understood. Here, using four different TRAF2-deficient cell lines (A20.2J, CH12.LX, HAP1 and MEFs) reconstituted with wild-type or phospho-mutant forms of TRAF2, along with immunoprecipitation, immunoblotting, gene expression and immunofluorescence analyses, we report that CD40 ligation elicits TBK1-mediated phosphorylation of TRAF2 at Ser-11. This phosphorylation interfered with the interaction between TRAF2’s RING domain and membrane phospholipids and enabled translocation of the TRAF2 complex from CD40 to the cytoplasm. We also observed that this cytoplasmic translocation is required for full activation of JNK and secondary phase of canonical NF-κB. Moreover, we found that in the absence of Ser-11 phosphorylation, the TRAF2 RING domain interacts with phospholipids, leading to the translocation of the TRAF2 complex to lipid rafts, resulting in its degradation and activation of the noncanonical NF-κB pathway. Thus, our results provide new insights into the CD40 signaling mechanisms whereby Ser-11 phosphorylation controls RING domain-dependent subcellular localization of TRAF2 to modulate the spatiotemporal activation of the JNK and NF-κB pathways.
