Severe BD was more frequent in men (OR=2.004, p=0.024), increasing with age (OR=1.021 per year, p=0.037), in the presence of skin manifestations (OR=4.711, p<0.001), specifically erythema nodosum (OR=8.381, p<0.001), and pseudofolliculitis (OR=2.910, p<0.001). In the multivariate model, variables independently associated with severe BD were male gender (Adjusted OR=1.961, p=0.047), erythema nodosum (Adjusted OR=8.561, p<0.001) and pseudofolliculitis (Adjusted OR=2.372, p=0.007).
Male gender, erythema nodosum, and pseudofolliculitis were independently associated with severe BD forms and therefore should serve as warning signs to the clinician.

The purpose of this study was to develop a fast and automatic algorithm to detect and segment lymphadenopathy from head and neck computed tomography (CT) examination.
An ensemble of three convolutional neural networks (CNNs) based on a U-Net architecture were trained to segment the lymphadenopathies in a fully supervised framework. The resulting predictions were assessed using the Dice similarity coefficient (DSC) on examinations presenting one or more adenopathies. On examinations without adenopathies, the score was given by the formula M/(M+A) where M was the mean adenopathy volume per patient and A the volume segmented by the algorithm. The networks were trained on 117 annotated CT acquisitions.
The test set included 150 additional CT acquisitions unseen during the training. The performance on the test set yielded a mean score of 0.63.
Despite limited available data and partial annotations, our CNN based approach achieved promising results in the task of cervical lymphadenopathy segmentation. It has the potential to bring precise quantification to the clinical workflow and to assist the clinician in the detection task.

To evaluate the time to hemoglobin oxygen desaturation in chickens (Gallus gallus domesticus) with and without preoxygenation before isoflurane induction of anesthesia and rocuronium-induced apnea.
Prospective, randomized crossover study.
A total of 10 healthy adult Lohmann Brown-Lite hens.
Hens were anesthetized with isoflurane for intravenous (IV) and intraarterial catheter placement and allowed to fully recover from anesthesia. Hens in the preoxygenation treatment were administered oxygen (2 L minute
) via a facemask for 3 minutes prior to induction of anesthesia with 3% isoflurane in oxygen. In the alternative treatment, hens were not preoxygenated prior to induction of anesthesia with isoflurane in oxygen. Apnea was then induced with rocuronium bromide (1.0 mg kg
) administered IV, and anesthesia was maintained with IV propofol infusion. A cloacal pulse oximeter measured hemoglobin oxygen saturation (SpO
). Time was recorded from the start of apnea until SpO
was 90% (desaturation). The trachd apnea does not significantly increase time until desaturation in hens.
To quantify induction time, reliability, physiological effects, recovery quality and dart volume of a novel formulation of alfaxalone (40 mg mL
) used in combination with medetomidine and azaperone for the capture and handling of wild bighorn sheep.
Prospective clinical study.
A total of 23 wild bighorn sheep (Ovis canadensis) in Sheep River Provincial Park, AB, Canada.
Free-ranging bighorn sheep were immobilized using medetomidine, azaperone and alfaxalone delivered with a remote delivery system. Arterial blood was collected for measurement of blood gases, physiologic variables (temperature, heart and respiratory rates) were recorded and induction and recovery length and quality were scored.
Data from 20 animals were included. Administered dose rates were alfaxalone (0.99 ± 0.20 mg kg
; 40 mg mL
), azaperone (0.2 ± 0.04 mg kg
; 10 mg mL
) and medetomidine (0.16 ± 0.03 mg kg
; 30 mg mL
). The mean drug volume injected was 1.51 mL. The median (range) induction time was 7.7 (5.8-9.7) minutes, and recovery was qualitatively smooth.
An increased concentration formulation of alfaxalone was administered in combination with medetomidine and azaperone, and resulted in appropriate anesthesia for the capture and handling of bighorn sheep. The dart volume was small, with potential for reducing capture-related morbidity.

There is a plethora of literature that has described the negative impact of the COVID-19 pandemic on the mental health of healthcare staff worldwide. Our aim was to investigate the physical and mental demands of mobile x-ray imaging on radiographers during the first wave of the COVID-19 pandemic, within a local NHS Trust.
A total of 16 participants from 1 NHS Trust took part within this study. Both quantitative and qualitative data was obtained through an online survey. Statistical data was obtained via the Trust Radiology Information System (RIS). Data was gathered for the thirteen weeks from 23rd March to 21st June 2020 (the first wave); direct comparison was made to the same period in 2019.
Three key themes emerged from the data. These include mental health challenges/work morale in Radiology, demand of mobile imaging and departmental and Trust-wide mental health support. Results indicate a high demand in mobile imaging which has made a significant difference in the working life of some radiographers.
The COVID-19 pandemic has significantly affected the mental health of a proportion of radiographers at this Trust. Results indicate high workload and demand in mobile imaging has made a significant difference to the working life of radiographers, specifically the ones who were relatively newly qualified.
Two key interventions are proposed from this study. The first one is to provide and promote mental health support within radiology departments. The second is to encourage dual working on mobile x-ray examinations to help manage the emotional and physical burden.

Guidelines concerning intravenous iodinated contrast media (CM) during computed tomography (CT) examinations are important to follow to minimize the risk for post-contrast acute kidney injury (PC-AKI). The purpose of this study was to investigate the radiology departmental policy compliance with Swedish guidelines concerning PC-AKI.
In February 2020, an electronic survey was distributed to the responsible radiographer at 41 radiology departments in all university hospitals and medium-sized hospitals in Sweden. The questions focused on routines around renal functional tests, individualized contrast administration and handling of patients with diabetes mellitus taking metformin.
The response rate was 83%. Seventy-six percent (n=26) of radiology departments calculated estimated glomerular filtration rate (eGFR) from serum creatinine prior to CM administration, but only 24% (n=8) followed the recommendation to calculate eGFR from both serum creatinine and cystatin C. For acute/inpatients, 55% (n=18) followee about the current level of compliance regarding PCI-AKI is important to maintain and develop effective clinical implementation of guidelines. The variation in practice seen in this study emphasizes the need of more effective implementation strategies to ensure adherence with best practice.
This study raises awareness of the importance of adhering to guidelines in healthcare. To have knowledge about the current level of compliance regarding PCI-AKI is important to maintain and develop effective clinical implementation of guidelines. The variation in practice seen in this study emphasizes the need of more effective implementation strategies to ensure adherence with best practice.
Recurrent angioedema (RecAE) has a substantial impact on patients' daily lives. However, there have been no disease-specific patient-reported outcomes (PROs) available in Japan to measure disease activity and health-related QoL impairment in such patients.
Japanese versions of the Angioedema Activity Score (AAS) and the Angioedema Quality of Life Questionnaire (AE-QoL) were examined for their validity and reliability. By using these questionnaires, the relationship between disease activity and QoL impairment among the Japanese population of RecAE were analyzed in real-world setting.
The Japanese AAS and AE-QoL domains showed good internal consistency of 0.967 and>0.835. For known group validity, AAS28 and AE-QoL total scores were higher in more severe patients than those with milder disease and QoL impairment, respectively. AAS28 showed strong correlation with indexes of disease activity, while the AE-QoL total score correlated with Dermatology Life Quality Index (DLQI). Sufficient reproductivity of the AAS and AE-QoL was shown by their intraclass correlation coefficients of 0.890 and 0.700. The Japanese population is characterized by the total score of AAS28, 34.3±38.8 (mean±SD); and AE-QoL, 38.7±25.2. Each domain score of AE-QoL was 32.4±29.7 in "Functioning", 35.0±27.8 in "Fatigue/mood", 50.7±30.6 in "Fears/shame", or 24.7±29.8 in "Food". Changes in AAS28 and AE-QoL positively correlated to Patient global assessment of disease activity and DLQI, respectively.
The Japanese AAS and AE-QoL are valid and reliable instruments for Japanese patients with RecAE, and active disease affecting QoL. They help assess disease activity and QoL of RecAE in routine patient care and clinical trials.

This study compared diagnostic rates and clinical predictors of discrepancies between diagnoses conferred via 1) a comprehensive neuropsychological evaluation and National Institute on Aging-Alzheimer's Association (NIA-AA) criteria versus 2) a cognitive screener and Diagnostic Statistical Manual of Mental Disorders (DSM-5) criteria.
Cross-sectional examination of baseline data from the Prevention of Alzheimer's dementia (AD) using Cognitive remediation and transcranial direct current stimulation in Mild Cognitive Impairment (MCI) and Depression (PACt-MD; ClinicalTrials.gov Identifier NCT02386670) trial.
Five geriatric psychiatry and memory clinics located at academic hospitals affiliated with the Department of Psychiatry, University of Toronto.
Older adults (N = 431) with a history of major depressive disorder (MDD) in remission, MCI, or both.
Main outcome was a comparison of NIA-AA diagnostic rates of MCI or dementia versus DSM-5 rates of mild or major neurocognitive disorder. Secondary analyses examined demographic, race, gender, premorbid intellectual ability, psychosocial, health-related, and genetic predictors of discrepancy between DSM-5 and NIA-AA diagnoses.
