Our results suggest that the diagnosis and prognosis of sepsis in emergency care should consider different clinical criteria, based on site of infection. Given the heterogeneity and interindividual variability of sepsis, a more individualised approach could help to direct treatment, monitor response and facilitate initial clinical decisions.

Polymyalgia rheumatica is the second most common inflammatory rheumatic disease of people >50 years. Glucocorticoid therapy is highly effective, but many patients require treatment for several years. Effective glucocorticoid sparing agents are still needed.

In this double-blind, multi-centre phase 2/3 clinical trial, we randomly assigned 36 patients with new onset polymyalgia rheumatica from three centres to receive subcutaneous tocilizumab (162 mg per week) or placebo for 16 weeks (11 ratio). All patients received oral prednisone, tapered from 20 mg to 0 mg over 11 weeks.The primary endpoint was the proportion of patients in glucocorticoid-free remission at week 16; key secondary endpoints, including time to first relapse and cumulative glucocorticoid dose at weeks 16 and 24, were evaluated.

From 20 November 2017 to 28 October 2019 39 patients were screened for eligibility; 19 patients received tocilizumab and 17 placebo. Glucocorticoid-free remission at week 16 was achieved in 12 out of 19 patients on tocilizumab (63.2%) and 2 out of 17 patients receiving placebo (11.8%, p=0.002), corresponding to an OR of 12.9 (95 % CI 2.2 to 73.6) in favour of tocilizumab. Mean (±SD) time to first relapse was 130±13 and 82±11 days (p=0.007), respectively, and the median (IQR) cumulative glucocorticoid dose was 727 (721-842) mg and 935 (861-1244) mg (p=0.003), respectively. Serious adverse events were observed in five placebo patients and one tocilizumab patient.

In patients with new onset polymyalgia rheumatica undergoing rapid glucocorticoid tapering, tocilizumab was superior to placebo regarding sustained glucocorticoid-free remission, time to relapse and cumulative glucocorticoid dose.

Synovial tissue research has become widely developed in several rheumatology centres, however, large discrepancies exist in the way synovial tissue is handled and, more specifically, how data pertaining to biopsy procedure, quality check and experimental results are reported in the literature. This heterogeneity hampers the progress of research in this rapidly expanding field. In that context, under the umbrella of European Alliance of Associations for Rheumatology, we aimed at proposing points to consider (PtC) for minimal reporting requirements in synovial tissue research.

Twenty-five members from 10 countries across Europe and USA met virtually to define the key areas needing evaluation and formulating the research questions to inform a systematic literature review (SLR). The results were presented during a second virtual meeting where PtC were formulated and agreed.

We evaluated real-world treatment persistence and effectiveness at 1 year following initiation of IL-12/23 inhibitor ustekinumab or a tumour necrosis factor inhibitor (TNFi) for psoriatic arthritis (PsA).

PsABio (NCT02627768), a prospective, observational study, followed patients with PsA prescribed first-line to third-line ustekinumab or TNFi. Drug persistence, effectiveness (achievement of clinical Disease Activity Index for Psoriatic Arthritis (cDAPSA) low disease activity (LDA)/remission and minimal disease activity/very low disease activity (MDA/VLDA)), and safety were assessed every 6 months. In addition to descriptive statistics, propensity score (PS)-adjusted comparisons across cohorts were performed.

At 1 year, overall persistence was similar in the ustekinumab (n=317/438, 72.4%) and TNFi (n=321/455, 70.5%) groups. PS-adjusted HR (95% CI) for stopping/switching ustekinumab versus TNFi was 0.82 (0.60; 1.13). cDAPSA LDA (including remission)/remission was achieved in 55.9%/22.1% of ustekinumab-trisons demonstrated comparable overall persistence, effectiveness and safety for both modes of action in PsA.

As a result of Covid-19, students in primary care now experience patient consultations predominantly remotely, with supervisors historically educating students in face-to-face contexts. There is a paucity of evidence regarding the facilitators and barriers to supervising students for excellent educational impact in the remote consultation environment.

To understand the facilitators and barriers to educating medical students using remote consultations in primary care, and the consequences for students in educational impact.

A realist evaluation methodology was adopted to identify causal chains of contexts, mechanisms, and outcomes describing how the teaching and learning functioned on a sample of medical students, and GP tutors from two UK medical schools.

An

developed from the literature and a scoping exercise informed the data collection tools. We collected qualitative data through online questionnaires (49 students, 19 tutors) and/or a semi-structured interview (8 students, 2 tutors). The data was coded to generate

configurations outlining how the teaching and learning operated.

The results demonstrated a sequential style of supervision can positively impact student engagement and confidence and highlighted a need to address student preparation for remote patient examinations. Students found passive observation of remote patient encounters disengaging, and in addition, reported isolation which impacted negatively on their experiences and perceptions of primary care.

Student and tutor experiences may improve through considering the supervision style adopted by tutors and interventions to reduce student isolation and disengagement when using remote patient consultations in primary care.

A cervical biopsy indicated metastatic carcinoma. On the diagnostic workup thoracic-abdominal-pelvic CT revealed augmented lymph nodes (LNs) in the retroperitoneum; Positron Emission Tomography-CT showed uptake in the LNs described and in two small areas in the pelvis; blood tests showed elevated CA125 and CA72.4. Another biopsy, considering a para-aortic LN, proved to be metastasis of a high-grade serous carcinoma (HGSC). Gynaecological exam and pelvic imaging were innocent. GW5074 molecular weight Diagnostic laparoscopy, including hysterectomy and bilateral adnexectomy, was performed and anatomopathological examination confirmed a HGSC in the fallopian tube (FT), in a tiny focus of 1.5 mm. The patient continued treatment with adjuvant chemotherapy. Literature review indicates that supraclavicular LN as first manifestation of FT carcinoma is not usual, and widespread lymphadenopathies with no macroscopic pelvic disease at diagnosis are even rarer.Here, we report a case of a patient in their mid 30s who presented with an elevated creatinine and was found to have a massive bladder diverticulum. The patient underwent a robotic-assisted diverticulectomy. They were later found to have a primary bladder neck obstruction on video urodynamics, and subsequently, underwent bladder neck incision, leading to significant improvement in urinary symptoms. Primary bladder neck obstruction is an overlooked cause of bladder diverticulum. While cystoscopy and cross-sectional imaging are frequently used in the initial evaluation of bladder diverticula, in the absence of an anatomic obstruction such as prostate enlargement, video urodynamics should be performed to assess for primary bladder neck obstruction.Odontogenic keratocyst (OKC) rarely appears in the buccal space. It is aggressive and infiltrative, and simple enucleation results in high recurrence. This case report describes an OKC located in the buccal space recurring twice in a 62-year-old man with a 25 mm diameter cystic lesion in the right pterygomandibular space. The multicystic lesion was enucleated. Subsequently, a recurrence was observed, and the gourd-shaped recurrent lesion was also enucleated. The difficulty in detaching the mass from the scar tissue resulted in the perforation of the cystic wall. Thereafter, a second recurrence was observed, and the tissue surrounding the unicystic recurrent lesion was excised. The histopathological features were consistent with those of OKC. The present case is the 11th reported case of OKC in the buccal space and the first with apparent recurrence. Since complete enucleation in the pterygomandibular space is difficult, excision along with the surrounding tissues could prevent recurrence.A 34-year-old man presented to our hospital with a 5-day history of progressive abdominal pain and fever. A CT scan identified extensive mesenteric lymphadenopathy. Initial diagnostic tests were inconclusive. Abdominal lymph node biopsy showed histiocytic necrotising lymphadenitis, compatible with Kikuchi-Fujimoto disease (KFD). This benign and self-limiting disease generally resolves following supportive treatment. In this case, remission occurred within 3 weeks of initial presentation. KFD is a very uncommon cause of lymphadenopathy, and selective mesenteric involvement is rare. Definitive diagnosis often requires lymph node biopsy. It is important to exclude more common and serious differential diagnoses associated with mesenteric lymphadenopathy, while maintaining a minimally invasive diagnostic approach, before progressing to nodal biopsy.In mammals, the conserved telomere binding protein Rap1 serves a diverse set of nontelomeric functions, including activation of the NF-kB signaling pathway, maintenance of metabolic function in vivo, and transcriptional regulation. Here, we uncover the mechanism by which Rap1 modulates gene expression. Using a separation-of-function allele, we show that Rap1 transcriptional regulation is largely independent of TRF2-mediated binding to telomeres and does not involve direct binding to genomic loci. Instead, Rap1 interacts with the TIP60/p400 complex and modulates its histone acetyltransferase activity. Notably, we show that deletion of Rap1 in mouse embryonic stem cells increases the fraction of two-cell-like cells. Specifically, Rap1 enhances the repressive activity of Tip60/p400 across a subset of two-cell-stage genes, including Zscan4 and the endogenous retrovirus MERVL. Preferential up-regulation of genes proximal to MERVL elements in Rap1-deficient settings implicates these endogenous retroviral elements in the derepression of proximal genes.
