Utilizing Clinical and Non-clinical Patient Factors in Predicting Cardiovascular Events in Patients on JAK Inhibitor Therapy: A Retrospective Cohort Study.

BACKGROUND: Patients with autoimmune rheumatic diseases (ARDs) taking JAK inhibitors may have an increased risk of cardiovascular events, especially if they have other health conditions. Identifying high-risk patients can inform targeted preventive care. This study assessed the value of age and deprivation decile in predicting cardiovascular events in patients on JAK inhibitors for ARDs. OBJECTIVE: To assess the predictive value of age and deprivation decile in identifying patients at risk of cardiovascular events while on JAK inhibitor therapy for ARDs. METHODS: This cross-sectional cohort study enrolled 309 patients with ARDs (mean age 59.3 years, 77% female) treated with JAK inhibitors at a UK teaching hospital. Baseline characteristics, including age, gender, ethnicity, and comorbidities, were collected. Cardiovascular events (myocardial infarctions, strokes, and cardiovascular-related deaths) that occurred while on JAK inhibitor therapy were identified retrospectively. Deprivation indices were calculated using socioeconomic factors. RESULTS: Multivariate logistic regression analysis, adjusting for potential confounders, showed that a model combining age and deprivation decile was statistically significant (p = 0.031) in predicting cardiovascular events. Neither age nor deprivation decile alone was statistically significant. Older patients had an odds ratio of 1.06 (95% CI: 1.00-1.13) for increased risk of cardiovascular events. The logistic regression model as a whole was statistically significant (Chi2(14) = 24.04, p = 0.031, n = 309). The AUC of the ROC curve was 0.837. CONCLUSION: Age and deprivation decile can effectively predict cardiovascular events in patients on JAK inhibitor therapy for ARDs. Incorporating these predictive tools into routine clinical practice can help identify patients who warrant intensified cardiovascular risk management.

Clinicians' Interpretation of Unreported Chest Radiographs in Biologic Prescription Workup Service: A Comprehensive Analysis.

Clinicians without a radiology specialization face difficulties when they attempt to interpret chest X-rays (CXRs), a crucial and extensively utilized diagnostic tool that plays a fundamental role in the detection of pulmonary and cardiovascular disorders. This cross-sectional study assessed the confidence and competence of clinicians, including junior specialty trainees, higher specialty trainees, and specialist nurses, in interpreting CXRs before starting biological treatment. An online survey was used to collect data from clinicians in various healthcare settings, focusing on their experience, training, confidence levels, and CXR interpretation proficiency. The survey uncovered clinicians' insufficient confidence in interpreting the pre-biological screening CXRs despite their clinical expertise. This uncertainty raises concerns about potential misinterpretations, affecting timely treatment decisions. A Kruskal-Wallis test indicated a significant difference between training levels required with a p-value of 0.001, rejecting the null hypothesis. Subsequently, a Dunn-Bonferroni test revealed that the higher specialty trainee-specialist nurse pair differed significantly, with the specialist nurse group requiring more training. This study highlighted the need for enhanced radiology education for clinicians involved in chest radiograph interpretation for pre-biological screening. Implementing a structured training program is essential to improve skills and ensure accurate interpretation of non-formally reported chest radiographs, ultimately enhancing patient outcomes and healthcare practices.

Chest X-ray Reporting: A Comparative Study of Specialist Nurses and Trainee Doctors' Knowledge in the Biologic Prescription Service.

With all the challenges facing the NHS at the current time, specialist nurses are fundamental and an important part of an ever-expanding NHS workforce. Furthermore, specialist nurses now possess more diversity and a wide range of advanced skills. In the field of rheumatology in most NHS hospitals, specialist nurses play a key role in biologic services to ensure that patients are promptly started on biological therapy to control their disease. An important element of this workup is the ability to comment on an unreported chest radiograph to facilitate a biological prescription. Some studies have shown that there is limited expertise among non-doctors with the required skills to review unreported chest X-rays confidently. The authors of this paper sought to explore whether this is the case among specialist nurses involved in the biologic prescription service among other clinicians in the same service. An online questionnaire was designed by the authors, which included seven questions and responses collected on a 5-point Likert scale. Trainee doctors, non-trainee grade doctors, and specialist nurses who were involved in the biologic prescribing team from Rheumatology, Dermatology, and Gastroenterology were invited. A total of 56 responses were obtained and analyzed. Descriptive and inferential statistics were obtained from the data. To determine if there was a statistical difference between the responses of trainee doctors and specialist nurses, the Kruskal-Wallis statistical test was used, and a post hoc test using the Dunn-Bonferroni test was used to analyze any statistically significant results. Regarding chest X-ray interpretation prior to starting biological treatment, only 8% of specialist nurses reported being confident, whereas 63% of trainees reported being confident. The Kruskal-Wallis test revealed a significant difference between specialist nurses' and doctors' confidence in interpreting unreported chest radiographs. The P-value is 0.001; thus, with available data, the null hypothesis is rejected. A Dunn-Bonferroni test (post hoc test) showed that, based on the available data, it can be assumed that the two groups had different levels of confidence between Specialist Nurses and trainee doctors. Chest X-ray interpretation skills are vital for specialist nurses in the context of biological therapy prescriptions. Therefore, we recommend access to resources, ongoing formal training, and educational sessions to help specialist nurses maintain their advanced skill sets and broaden their scope of practice to those without the required expertise.

Pericarditis of Polyarteritis Nodosa.

Polyarteritis nodosa (PAN) is a rare systemic vasculitis characterised by necrotising inflammation of medium-sized arteries. PAN can affect patients of any age, gender, or ethnic background. Its highest incidence is in the fifth-sixth decade of life, with a slight male-to-female predilection. PAN can be idiopathic or secondary to a multitude of systemic conditions, such as infection, haematological malignancy, or autoinflammatory disorders. PAN has a broad spectrum of possible clinical manifestations the most common being constitutional symptoms, such as fever and myalgia. While cardiac involvement is well-described and is a common cause of mortality, it is exceedingly uncommon as the initial presentation. Below, we describe a case of a female in her 60s who presented with pericarditis as the first manifestation of PAN.

Progressive Multifocal Leukoencephalopathy Mimicking a Cerebral Vasculitis Flare.

We report a case of a 68-year-old woman with a background of primary cerebral vasculitis, which was diagnosed two years ago. She appeared to have had a recurrence of her symptoms with new onset history of expressive dysphasia, right-sided upper limb weakness, and right-sided facial weakness during a rheumatology clinic visit. The patient was on maintenance azathioprine for her cerebral vasculitis at the time of presentation. She had received a total of 2 g of rituximab through intravenous infusion, with a two-week interval between doses. Additionally, she had undergone intravenous cyclophosphamide treatment (15 mg/kg) following the standard vasculitis regimen for induction remission therapy, which was administered at the time of her diagnosis two years prior. Initial imaging on non-contrast computed tomography head after admission to the emergency department did not show any acute neurological findings. Further imaging studies revealed changes in the right parietotemporal white matter T2 hyperintensity with similar changes on the left frontal and left parietal lobes suggestive of progressive multifocal leukoencephalopathy (PML). A magnetic resonance imaging (MRI) of the brain conducted three months prior was found to be unremarkable. Cerebrospinal fluid (CSF) polymerase chain reaction (PCR) testing confirmed the presence of polyoma John Cunningham (JC) virus deoxyribonucleic acid (DNA). This case highlights that PML should be an important differential to consider in any immunocompromised patient who presents with new stroke-like features.
