Patients with longstanding pPatients with longstanding psoriatic arthritis can achieve DAPSA remission or low disease activity and it correlates to better functional outcomes: results from a Latin-American real-life cohort.

Background: Patients with psoriatic arthritis (PsA) experience reduced physical function and impaired quality of life. Better patient-reported functional outcomes are found when lower disease activity is achieved.

Objectives: To evaluate the variation of physical function by HAQ-DI over time in PsA patients treated with standard therapy in a real-life setting: to verify predictors of achieving a minimum clinically important difference (MCID) in function by HAQ-DI (ΔHAQ-DI ≤ - 0.

Navigating the Multidimensional Impact of Living with Hidradenitis Suppurativa: An In-Depth Netnographic Study on Social Media Platforms.

Introduction: Hidradenitis suppurativa (HS) is a chronic skin condition causing considerable distress. It impacts mobility, social interaction, and quality of life. In Brazil, there is a notable gap in epidemiological data and patient experiences regarding HS.

Requirements for Brazilian Outpatient Centers of Excellence in Hidradenitis Suppurativa: Consensus Co-Creative Study.

Background: Hidradenitis suppurativa (HS) is a chronic skin condition. Its complexity and impact on patients highlight the need for multidisciplinary care that can address the physical, psychological, and social aspects. Centers of excellence can ideally provide the necessary infrastructure, resources, and expertise to effectively treat HS.

Cross talk between peritoneal macrophages and B-1 cells in vitro.

B-1 cells constitute a distinct B cell population with unique phenotypic and functional characteristics. They represent the main B cell population found in mouse peritoneal and pleural cavities. The communication between B-1 cells and peritoneal macrophages has been previously studied, and the effect this interaction has on macrophages has been previously described.

B16 melanoma cells increase B-1 cell survival, IL-10 production and radioresistance in vitro.

B-1 cells can be differentiated from B-2 cells because they are predominantly located in the peritoneal and pleural cavities and have distinct phenotypic patterns and activation properties. The role of both cell populations in cancer progression is still controversial. Previous studies have indicated that direct contact between B-1 cells and B16 melanoma tumor cells (B16) increases the metastatic potential of the tumor cells.

Adjuvant effect of killed Propionibacterium acnes on mouse peritoneal B-1 lymphocytes and their early phagocyte differentiation.

B-1 lymphocytes are the predominant cells in mouse peritoneal cavity. They express macrophage and lymphocyte markers and are divided into B-1a, B-1b and B-1c subtypes. The role of B-1 cells is not completely clear, but they are responsible for natural IgM production and seem to play a regulatory role.
