Objective Somatic items used in depression assessments can potentially overlap with symptoms related to physical illness, including systemic sclerosis (SSc). No studies have looked at whether somatic depression items may be influenced by diffuse versus limited SSc disease subtypes, which are associated with varying degrees of symptom presentation.

Objective The objective of this study was to describe the longitudinal disease course and pulmonary outcomes of North American patients with melanoma differentiation–associated protein 5 (MDA5) antibody–associated dermatomyositis (DM). Methods Thirty patients with MDA5 antibody–associated DM were identified in a single‐center longitudinal cohort of 352

Trajectories of Physical Function in Canadian Children with Juvenile Idiopathic Arthritis
Objectives We describe trajectories of physical function in children newly diagnosed with juvenile idiopathic arthritis (JIA) and identify trajectories with persisting functional impairments and associated baseline characteristics. Methods We included patients enrolled in the Canadian Alliance of Pediatric Rheumatology Investigators (CAPRI) Registry ...

The study of mating is one of the most active areas in evolutionary ecology. What fuels this research is curiosity about a stunning diversity of ways in which zygotes are formed. Many plants and some animals can reproduce without combining gametes. Many other plants combine gametes but do so within the same individual (selfing).

Current Biology, 2022
Most vertebrates, including all mammals and birds, are sexually reproducing organisms. The implication of sexual reproduction is that an adult bird exists because a male transferred sperm to the reproductive tract of a female during copulation, one of the sperm fertilized an egg, and the ensuing embryo developed into an individual male or female that ...

AbstractPatterns of mating vary with the reproductive biology and spatial structure of a species, and combine to influence levels and dynamics of genetic diversity. Knowledge of all aspects of a species' mating system is necessary to understand the distribution of genetic variation between individuals, gene flow within and between populations, what ...

Abstract Defining a population mating strategy has inherent problems. All individuals are of different quality and face unique conditions during reproduction. Thus, the costs and benefits for specific individuals must be considered when examining their mating arrangement.
