Metabolic syndrome and psoriatic arthritis: the role of weight loss as a disease-modifying therapy.

Psoriatic arthritis (PsA) is an inflammatory joint and entheseal disease associated with significant personal and public health burden. PsA has a prevalence of up to 1%, affecting ~20% of people suffering with psoriasis. PsA is frequently accompanied by metabolic syndrome (MetS), and both conditions are characterised by a chronic pro-inflammatory state, with several key cytokines in PsA (interleukin (IL)-17 and IL-23) also elevated in those with MetS.

Insomnia and short sleep duration, but not chronotype, is associated with chronic widespread pain: Mendelian randomization study.

Objectives: Sleep disturbance has been associated with chronic widespread pain (CWP), but their causal relationship remains unclear. We aimed to examine the causal relationship and direction between CWP and sleep traits, namely insomnia, sleep duration and chronotype, using Mendelian Randomization.

Method: We used genetic association data from ~0.

Using Polygenic Risk Scores to Aid Diagnosis of Patients With Early Inflammatory Arthritis: Results From the Norfolk Arthritis Register.

Objective: There is growing evidence that genetic data are of benefit in the rheumatology outpatient setting by aiding early diagnosis. A genetic probability tool (G-PROB) has been developed to aid diagnosis has not yet been tested in a real-world setting. Our aim was to assess whether G-PROB could aid diagnosis in the rheumatology outpatient setting using data from the Norfolk Arthritis Register (NOAR), a prospective observational cohort of patients presenting with early inflammatory arthritis.

Comparison of clinical features between patients with anti-synthetase syndrome and dermatomyositis: results from the MYONET registry.

Objectives: To compare clinical characteristics, including the frequency of cutaneous, extramuscular manifestations and malignancy, between adults with anti-synthetase syndrome (ASyS) and DM.

Methods: Using data regarding adults from the MYONET registry, a cohort of DM patients with anti-Mi2/-TIF1γ/-NXP2/-SAE/-MDA5 autoantibodies, and a cohort of ASyS patients with anti-tRNA synthetase autoantibodies (anti-Jo1/-PL7/-PL12/-OJ/-EJ/-Zo/-KS) were identified. Patients with DM sine dermatitis or with discordant dual autoantibody specificities were excluded.

Utility of Musculoskeletal Ultrasound in Psoriatic Arthritis.

Purpose: Psoriatic arthritis (PsA) is a chronic autoimmune disease that causes a variety of musculoskeletal abnormalities. Musculoskeletal ultrasound in PsA is becoming increasingly popular, both in clinical practice and research. This narrative reviews recent literature on the utility of ultrasound in PsA.

Genetic Studies Investigating Susceptibility to Psoriatic Arthritis: A Narrative Review.

Purpose: Approximately 30% of patients with psoriasis will develop psoriatic arthritis (PsA), leading to a decreased quality of life for the patient caused by increasing disability and additional health complications. The identification of risk factors for the development of PsA would facilitate the development of risk prediction models in which patients with psoriasis at high risk of developing PsA could be targeted in a stratified medicine approach, enabling early intervention and treatment. PsA is known to have a genetic contribution to susceptibility, and the identification of genetic risk factors that differentiate PsA from cutaneous-only psoriasis is a key area of research.

Simulating Realistic Continuous Glucose Monitor Time Series By Data Augmentation.

Background: Simulated data are a powerful tool for research, enabling benchmarking of blood glucose (BG) forecasting and control algorithms. However, expert created models provide an unrealistic view of real-world performance, as they lack the features that make real data challenging, while black-box approaches such as generative adversarial networks do not enable systematic tests to diagnose model performance.

Methods: To address this, we propose a method that learns missingness and error properties of continuous glucose monitor (CGM) data collected from people with type 1 diabetes (OpenAPS, OhioT1DM, RCT, and Racial-Disparity), and then augments simulated BG data with these properties.

A Case of IgG4-Related Disease and Membranous Nephropathy Associated with Thrombospondin Type-1 Domain-Containing 7A.

Background: IgG4-related disease (IgG4-RD) is a systemic multi-organ inflammatory disorder which affects the kidney 20% of the time. Patients with intrinsic IgG4-related kidney disease (IgG4-RKD) often have tubulointerstitial nephritis (TIN) whereas glomerular lesions like membranous nephropathy (MN) are less common. Antibodies to thrombospondin type-1 domain-containing 7A (THSD7A) have been described in primary MN, but never in association with IgG4-RKD.

Renal sarcoidosis associated with certolizumab pegol treatment for psoriatic arthritis.

We present a case of certolizumab-associated renal sarcoidosis, the first reported case in a patient with psoriatic arthritis (PsA) that was effectively treated with corticosteroids. A 55-year-old Caucasian man with PsA diagnosed at age 47 and plaque psoriasis since his early twenties was on certolizumab pegol (CZP) for 7 months before presenting to the emergency department with seizures and renal failure. A renal biopsy confirmed renal sarcoidosis.

SARS-CoV-2 vaccination and new-onset myasthenia gravis: A report of 7 cases and review of the literature.

Myasthenia gravis (MG) is an antibody-mediated immune disorder of the neuromuscular junction. SARS-CoV-2 is now recognised as a trigger factor for autoimmune diseases and to cause immune-mediated dysregulation, likely due to molecular mimicry induced by viral antigens. SARS-CoV-2 vaccination, similarly, results in exposure to viral antigen.

Pregnancy outcomes of a joint obstetric and rheumatology clinic in a tertiary centre: a 2-year retrospective study of 98 pregnancies.

Objectives: The purpose of this study was to describe the maternal and fetal outcomes in patients with inflammatory rheumatic diseases attending a joint rheumatology and obstetric clinic in the UK.

Methods: Electronic records of 98 patients attending the joint rheumatology and obstetric clinic between January 2018 and January 2020 were analysed. Data on patient demographics, characteristics (including age, ethnicity, diagnosis, and medications taken during pregnancy), pregnancy outcomes (miscarriage, stillbirth or live birth), maternal complications [infection, post-partum haemorrhage (PPH) or pre-eclampsia] and fetal complications (sepsis, congenital heart block, prematurity and low birth weight) were tabulated.

Septic arthritis caused by in a patient with systemic lupus erythematosus.

is one of the most common commensal organisms of the genitourinary tract. Immunocompromised patients are susceptible to developing severe infections secondary to , and rarely, septic arthritis. This case report describes the occurrence of septic arthritis secondary to in a 27-year-old woman with systemic lupus erythematosus (SLE), who presented with a 2-week history of left elbow swelling and tenderness, elevated inflammatory markers and joint aspiration findings consistent with infection.

Hereditary haemochromatosis presenting to rheumatology clinic as inflammatory arthritis.

Hereditary haemochromatosis (HH) is the most commonly identified genetic disorder in Caucasians. HH has a wide variety of clinical manifestations. As such, the presenting complaint in new diagnoses of HH can be non-specific such as fatigue; however, joint symptoms such as arthralgia are also common.

A Kinematic Comparison Between Sit-to-Stand Movements and Individual Cycles of the 5-Cycle Sit-to-Stand Test.

Objective: The 5-cycle sit-to-stand (5XSTS) test is frequently used to test physical function for different clinical populations, with time to complete as the measured outcome. This study evaluated the similarity of kinematics between a single cycle of the STS movement and individual cycles of the 5XSTS test.

Methods: Lower extremity, pelvis, and thorax kinematic data were monitored as 20 participants (aged 18-40) completed 5 trials of the STS movement and 1 trial of the 5XSTS test.

Online Learning and Residents' Acquisition of Mechanical Ventilation Knowledge: Sequencing Matters.

Objective: Rapid advancements in medicine and changing standards in medical education require new, efficient educational strategies. We investigated whether an online intervention could increase residents' knowledge and improve knowledge retention in mechanical ventilation when compared with a clinical rotation and whether the timing of intervention had an impact on overall knowledge gains.

Design: A prospective, interventional crossover study conducted from October 2015 to December 2017.

Replicability, Reproducibility, and Agent-based Simulation of Interventions.

Secondary use of medical data and use of observational data for causal inference has been growing. Yet these data bring many challenges such as confounding due to unobserved variables and variation in medical processes across settings. Further, while methods exist to handle some of these problems, researchers lack ground truth to evaluate these methods.
