Basic Science and Pathogenesis.

Background: Previously, we found that germline C3 deletion protected cognition and hippocampal synapses in aged APP/PS1dE9 mice, despite increasing Aß plaques. Here, we crossed our C3 inducible conditional mouse model to APP knockin mice to determine whether global C3 lowering in an adult amyloid mouse model would be protective.

Methods: C3;Rosa26-Cre-ERT2 (C3iKO) mice were crossed to C3;APP mice to generate APP;C3iKO mice, which received 75 mg/kg tamoxifen (TAM; n = 16) or corn oil (CO; n = 15) for 5 days at 3.

Total and High-density Lipoprotein Cholesterol in Adults: United States, August 2021-August 2023.

Introduction: This report presents prevalence of high total cholesterol and low high-density lipoprotein cholesterol (HDL-C) by sex and age group for adults age 20 and older from the August 2021-August 2023 National Health and Nutrition Examination Survey (NHANES). Trends in the prevalence of high total cholesterol and low HDL-C are also presented.

Methods: Data from the August 2021-August 2023 NHANES were used to estimate the prevalence of high total cholesterol (240 mg/dL or higher) and low HDL-C (less than 40 mg/dL).

Tumor Lysis Syndrome in Acute Myeloid Leukemia Patients Treated With a Venetoclax Based Regimen.

Venetoclax with hypomethylating agents (HMA) is the standard of care for acute myeloid leukemia (AML) in patients ineligible for intensive chemotherapy and is associated with tumor lysis syndrome (TLS). TLS prophylaxis and the use of Cairo Bishop versus Howard diagnostic criteria are not standardized. Here we report TLS prophylaxis and incidence in a retrospective cohort of 100 consecutive AML patients treated with venetoclax and HMA.

Resting Heart Rate and Associations With Clinical Measures From the Project Baseline Health Study: Observational Study.

Background: Though widely used, resting heart rate (RHR), as measured by a wearable device, has not been previously evaluated in a large cohort against a variety of important baseline characteristics.

Objective: This study aimed to assess the validity of the RHR measured by a wearable device compared against the gold standard of ECG (electrocardiography), and assess the relationships between device-measured RHR and a broad range of clinical characteristics.

Methods: The Project Baseline Health Study (PHBS) captured detailed demographic, occupational, social, lifestyle, and clinical data to generate a deeply phenotyped cohort.

Impact of trace mineral supplementation and translucency score on eggshell quality, hatchability, fertility, and chick quality.

The broiler breeder industry is facing a problem with fertility, hatchability, and the number of broiler breeder eggs produced per hen. The supplementation of trace minerals such as zinc, manganese, and copper in broiler breeder diets has been previously linked to an increase in eggshell quality, which may lead to increased fertility, hatchability, and chick quality. The objective of this study was to explore the effect of amino-acid complexed mineral supplementation on eggshell quality, fertility, hatchability, chick quality, and shell translucency.
