Risk Adjustment in Medical Research: A Bird's Eye View.

Making correct decisions is of paramount importance in clinical medicine and health-related disciplines. Randomized clinical trials are considered the gold-standard type of study for the assessment of the efficacy of a treatment. However, conducting a randomized clinical trial is not always possible; observational studies should be conducted, instead.

Association Between Race and Comorbid Conditions Among Older Adults with Dementia.

Dementia is estimated to affect over 150 million individuals by 2050. Individuals with dementia commonly suffer from other comorbid conditions which can affect quality of life and result in increased health care expenditures. We conducted this study to determine the frequency of comorbid conditions between representative samples of non-Hispanic Black and White US adults aged ≥65 with dementia.

A comprehensive engineering strategy improves potency and manufacturability of a near pan-neutralizing antibody against HIV.

Anti-HIV envelope broadly neutralizing antibodies (bnAbs) are alternatives to conventional antiretrovirals with the potential to prevent and treat infection, reduce latent reservoirs, and/or mediate a functional cure. Clinical trials with "first generation" bnAbs used alone or in combination show promising antiviral effects but also highlight that additional engineering of "enhanced" antibodies will be required for optimal clinical utility, while preserving or enhancing cGMP manufacturing capability. Here we report the engineering of an anti-CD4 binding-site (CD4bs) bnAb, N49P9.

Deficient Generation of Spike-Specific Long-Lived Plasma Cells in the Bone Marrow After Severe Acute Respiratory Syndrome Coronavirus 2 Infection.

Generation of a stable long-lived plasma cell (LLPC) population is the sine qua non of durable antibody responses after vaccination or infection. We studied 20 individuals with a prior coronavirus disease 2019 infection and characterized the antibody response using bone marrow aspiration and plasma samples. We noted deficient generation of spike-specific LLPCs in the bone marrow after severe acute respiratory syndrome coronavirus 2 infection.
