RESUMO
Guselkumab treatment outcomes and persistence were assessed in a real-world cohort of Finnish patients with difficult-to-treat plaque psoriasis over a median follow-up of 1 year. Data on 181 patients who initiated guselkumab at the 15 study centres were collected retrospectively from the patient charts. Prior exposure to biologic therapies was common, with 56% and 35% having used at least 1 and 2 biologics, respectively. Median guselkumab treatment duration was 11 months with 21 patients (12%) discontinuing treatment during follow-up. Of 85 patients with a follow-up duration of at least 1 year, 73 (86%) were still on guselkumab at 1 year. Significant improvements during follow-up were seen in the absolute Psoriasis Area and Severity Index (PASI) scores with 32 patients (80%) having absolute PASI ≤ 2 after a 9-14-month treatment. Guselkumab treatment was effective and treatment persistence was high in the nationwide Finnish real-life setting.

The entorhinal cortex is one of the first regions to exhibit neurodegeneration in Alzheimer's disease, and as such identification of entorhinal cortex dysfunction may aid detection of the disease in its earliest stages. Extensive evidence demonstrates that the entorhinal cortex is critically implicated in navigation underpinned by the firing of spatially modulated neurons. This study tested the hypothesis that entorhinal-based navigation is impaired in pre-dementia Alzheimer's disease. Forty-five patients with mild cognitive impairment (26 with CSF Alzheimer's disease biomarker data: 12 biomarker-positive and 14 biomarker-negative) and 41 healthy control participants undertook an immersive virtual reality path integration test, as a measure of entorhinal-based navigation. Behavioural performance was correlated with MRI measures of entorhinal cortex volume, and the classification accuracy of the path integration task was compared with a battery of cognitive tests considered sensitive and specific for early Alzheimer's disease. Biomarker-positive patients exhibited larger errors in the navigation task than biomarker-negative patients, whose performance did not significantly differ from controls participants. Path-integration performance correlated with Alzheimer's disease molecular pathology, with levels of CSF amyloid-ß and total tau contributing independently to distance error. Path integration errors were negatively correlated with the volumes of the total entorhinal cortex and of its posteromedial subdivision. The path integration task demonstrated higher diagnostic sensitivity and specificity for differentiating biomarker positive versus negative patients (area under the curve = 0.90) than was achieved by the best of the cognitive tests (area under the curve = 0.57). This study demonstrates that an entorhinal cortex-based virtual reality navigation task can differentiate patients with mild cognitive impairment at low and high risk of developing dementia, with classification accuracy superior to reference cognitive tests considered to be highly sensitive to early Alzheimer's disease. This study provides evidence that navigation tasks may aid early diagnosis of Alzheimer's disease, and the basis of this in animal cellular and behavioural studies provides the opportunity to answer the unmet need for translatable outcome measures for comparing treatment effect across preclinical and clinical trial phases of future anti-Alzheimer's drugs.

OBJECTIVES: To codesign safety-netting strategies for primary and emergency care settings by integrating the experiences and ideas of patients, carers and clinicians. DESIGN: A codesign process involving two focus group discussions, eight individual interviews and five workshops. All sessions were audio recorded and transcribed verbatim. Data were analysed using qualitative content analysis and reported using the Consolidated criteria for Reporting Qualitative research guidelines. SETTING: Primary and emergency care in Sweden, focusing on the Stockholm region. PARTICIPANTS: 7 (5 women) individuals with patient expertise, 1 (man) individual with carer expertise, 18 (12 women) individuals with clinical expertise. RESULTS: Three main categories reflecting strategies for applying safety-netting were developed: first, conveying safety-netting advice, which involves understanding patient concerns, tailoring communication and using appropriate modalities for communicating; second, ensuring common understanding, which involves summarising information, asking a teach-back question and anticipating questions post consultation; and third, supporting safety-netting behaviour, which involves facilitating reconsultation, helping patients and carers to navigate the health system and explaining the care context and its purpose. CONCLUSIONS: Our study highlights the collaborative nature of safety-netting, engaging both the clinician and patient, sometimes supported by carers, in an iterative process. Adding to previous research, our study also emphasises the importance of anticipating postconsultation inquiries and facilitating reconsultation.

Eccrine poroma can mimic benign and malignant melanocytic and non-melanocytic lesions. To date, little is known about the dermoscopic features of this condition. Seven histopathologically proven cases of eccrine poroma were examined using dermoscopy by three independent dermatologists. Both glomerular and hairpin vessels were observed in 71% of cases, whereas linear irregular vessels were observed in 43% of cases. A white-to-pink halo surrounding the vessels and multiple pink-white structureless areas were also frequently found (in 86% and 71% of cases, respectively). Three dermoscopic "profiles" were identified, all characterized by the presence of a white-to-pink halo surrounding the vessels, as well as by the association of two additional different features, namely: glomerular vessels and pink-white structureless areas, glomerular and linear irregular vessels, hairpin vessels and linear irregular vessels. However, due to the small number of lesions studied so far, we suggest that these profiles should be considered as likely, but not definitely pathognomonic signs of eccrine poroma.
