Egg injection has been used for decades to determine embryonic mortality and developmental effects of chemical exposures in birds. Specific egg injection methods affect how well these studies replicate the process of chemical delivery to the embryo via maternal deposition, yet few data are available to compare exposure-response relationships between egg injection and maternal transfer studies. This information gap creates uncertainty when considering egg injection studies for assessment of potential adverse effects in wild birds.

Background: Uncertainty is present in many situations in dental practice, but must not prevent wise clinical decision-making. Dental education should acknowledge uncertainty and teach useful management strategies. This study explored if dental students are aware of, and comfortable with uncertainty.

Background: Uncertainty exists regarding patient outcomes when using TNF inhibitors versus other biological and targeted synthetic disease-modifying antirheumatic drugs (DMARDs) in rheumatoid arthritis-associated interstitial lung disease (ILD). We compared survival and respiratory hospitalisation outcomes following initiation of TNF-inhibitor or non-TNF inhibitor biological or targeted synthetic DMARDs for treatment of rheumatoid arthritis-associated ILD.
Methods: We did a retrospective, active-comparator, new-user, observational cohort study with propensity score matching following the target trial emulation framework using US Department of Veterans Affairs (VA) electronic and administrative health records.

Background: C3 glomerulopathy (C3G) is a rare disease affecting the complement alternative pathway, categorized into dense deposit disease and C3 glomerulonephritis. Dense deposit disease predominantly affects younger individuals, while C3 glomerulonephritis tends to manifest in older populations. The diseases are characterized by dysregulation of the complement alternative pathway, leading to the deposition of complement components in the glomeruli and subsequent renal dysfunction.

Importance: An unhealthy lifestyle is believed to increase the development and persistence of low back pain, but there is uncertainty about whether integrating support for lifestyle risks in low back pain management improves patients' outcomes.
Objective: To assess the effectiveness of the Healthy Lifestyle Program (HeLP) compared with guideline-based care for low back pain disability.
Design, Setting, And Participants: This superiority, assessor-blinded randomized clinical trial was conducted in Australia from September 8, 2017, to December 30, 2020, among 346 participants who had activity-limiting chronic low back pain and at least 1 lifestyle risk (overweight, poor diet, physical inactivity, and/or smoking), referred from hospital, general practice, and community settings.
