Development of a questionnaire to assess the patient perspective regarding challenges in psoriatic arthritis treatment-a mixed-methods study.

Background: Limited data exist on psoriatic arthritis (PsA) treatment in lower-income regions, particularly from the patient perspective. This study explores the challenges faced by socioeconomically vulnerable PsA patients and the reasons for non-adherence to treatment guidelines. The main objective of the study is to develop a questionnaire to identify the primary challenges in PsA treatment adherence and to analyze its feasibility while simultaneously understanding the target population's unique characteristics.

Assessment of muscle mass using chest computed tomography-based quantitative and qualitative measurements in patients with systemic sclerosis: A retrospective study with cross-sectional and longitudinal analyses.

Background/ Purpose: Sarcopenia has been increasingly studied in systemic sclerosis (SSc), which is one of the most lethal autoimmune diseases, mainly due to lung involvement. Our objective was to study the associations of myopenia and/or myosteatosis with clinical features of SSc and subsequent adverse outcomes.

Methods: This is a retrospective study with cross-sectional and longitudinal analyses, in which patients with SSc were consecutively included in the outpatient clinic of a tertiary university hospital between 2012 and 2021.

Physical frailty in patients with systemic sclerosis.

Introduction: Systemic sclerosis (SSc) is a chronic disease characterized by autoimmunity, vasculopathy and fibrosis of several organs, such as skin, lungs, and heart. During the disease course, patients with SSc are prone to accumulating multiple organ damage and increasing their vulnerability to adverse outcomes. This increased vulnerability to adverse outcomes when exposed to a stressor among people of the same age is known as frailty.

Effect of cefepime dose on mortality of patients with Gram-negative bacterial bloodstream infections: a prospective cohort study.

Objectives: There are controversies regarding the association of cefepime therapy with increased mortality among patients with infections caused by Gram-negative bacteria (GNB). We evaluated the effect of cefepime on the mortality of patients with GNB bloodstream infections (BSIs).

Methods: A prospective cohort study was conducted in adult patients with creatinine ≤1.

Endotoxin exposure and inflammation markers among agricultural workers in Colorado and Nebraska.

The adverse respiratory effects of agricultural dust inhalation are mediated in part by endotoxin, a constituent of gram-negative bacterial cell walls. This study quantified personal work-shift exposures to inhalable dust, endotoxin, and its reactive 3-hydroxy fatty acid (3-OHFA) constituents among workers in grain elevators, cattle feedlots, dairies, and on corn farms. Exposures were compared with post-work-shift nasal lavage fluid inflammation markers and respiratory symptoms.
