High Health Care Utilization Preceding Diagnosis With Juvenile Idiopathic Arthritis

Arthritis Care &Research, EarlyView.
Objective Although early diagnosis improves long‐term outcomes, patients with juvenile idiopathic arthritis (JIA) often experience prolonged, circuitous paths to diagnosis. To inform diagnostic improvement, we sought to characterize health care utilization in the year preceding diagnosis. Methods We identified 10,021 patients with an incident diagnosis

Short‐Term Response to Biologic Therapy in Psoriatic Arthritis Is Not Influenced by Disease Duration at Initiation of Therapy

Arthritis Care &Research, EarlyView.
Objective We aimed to determine whether the short‐term response to biologics in biologic‐naive psoriatic arthritis (PsA) is better in patients initiating biologic treatment early in the disease course. Methods Patients with PsA who started on biologic therapy from the year 2000 to 2025 were included for analysis.

ON THE TIME VALUE OF RUIN IN THE DISCRETE TIME RISK MODEL [PDF]

Using an approach similar to that of Gerber and Shiu (1998), a recursive formula is given for the expected discounted penalty due at ruin, in the discrete time risk model. With it the joint distribution of three random variables is obtained; time to ruin,

Dependent Discrete Risk Processes - Calculation of the Probability of Ruin

Operations Research and Decisions, 2010
This paper is devoted to discrete processes of dependent risks. The random variables describing the time between claims can be dependent in such processes, unlike under the classical approach.

Risk measures versus ruin theory for the calculation of solvency capital for long-term life insurances

Dependence Modeling, 2016
The purpose of this paper is twofold. First we consider a ruin theory approach along with risk measures in order to determine the solvency capital of long-term guarantees such as life insurances or pension products.

Beyond Visual Scoring: Computational Computed Tomography Analysis for High‐Resolution Computed Tomography–Based Quantification of Interstitial Lung Disease in Inflammatory Rheumatic Disease

Arthritis Care &Research, EarlyView.
Interstitial lung disease (ILD) is a significant cause of morbidity and mortality in patients with inflammatory rheumatic disorders (IRDs). High‐resolution computed tomography (HRCT) is widely considered the gold standard for the noninvasive assessment of ILD; however, its interpretation is constrained by substantial interobserver variability and the ...

On the Expected Discounted Penalty Function for a Markov Regime-Switching Insurance Risk Model with Stochastic Premium Income

Discrete Dynamics in Nature and Society, 2013
We consider a Markovian regime-switching risk model (also called the Markov-modulated risk model) with stochastic premium income, in which the premium income and the claim occurrence are driven by the Markovian regime-switching process.

Validation of Patient‐Reported Outcomes Measurement Information System (PROMIS) Pediatric Measures for Children With Chronic Nonbacterial Osteomyelitis

Arthritis Care &Research, EarlyView.
Objective To assess the validity of the Patient‐Reported Outcomes Measurement Information System (PROMIS) Pediatric measures in patients with chronic nonbacterial osteomyelitis (CNO). Methods Within the longitudinal patient registry of CNO, English‐speaking patients aged 8 years and older self‐reported PROMIS Pediatric measures of fatigue, pain ...

Study of the Effect of Wind Flow around the Ruin of a Fortified Tower Variously Covered by a Flat Roof: Analysis of the Extreme Values of Exterior Pressure and Surface Friction Coefficients

Slovak Journal of Civil Engineering
An analysis of the effect of the covering of a ruin by a flat roof of various sizes and positions is presented. The ruin has almost cube-like proportions, with an open roof plane and an open destroyed corner.

Complete monotonicity for the ruin-time density in the Cramér–Lundberg model

Results in Applied Mathematics
In this article, we study complete monotonicity of the defective ruin-time density in the classical Cramér–Lundberg model for exponential, Erlang, and two-phase hyperexponential claim-size distributions.
