Disordered eating attitudes and behaviours among older adults with type 1 diabetes: An exploratory study.

Aims: We explored the prevalence of disordered eating behaviours (DEBs) and attitudes among older adults with type 1 diabetes (T1D) and associations with demographic and clinical variables.

Methods: Adults aged ≥65 years with T1D from a university-affiliated hospital system completed an electronic survey (September to November 2023) including the Diabetes Eating Problem Survey-Revised (DEPS-R). Clinical data were extracted from medical records.

Dysregulated alveolar epithelial cell progenitor function and identity in Hermansky-Pudlak syndrome.

Hermansky-Pudlak syndrome (HPS) is a genetic disorder of endosomal protein trafficking associated with pulmonary fibrosis in specific subtypes, including HPS-1 and HPS-2. Single mutant HPS1 and HPS2 mice display increased fibrotic sensitivity while double mutant HPS1/2 mice exhibit spontaneous fibrosis with aging, which has been attributed to HPS mutations in alveolar epithelial type II (AT2) cells. We utilized HPS mouse models and human lung tissue to investigate mechanisms of AT2 cell dysfunction driving fibrotic remodeling in HPS.

SEROCONVERSION CAN PRECEDE CULTURE CONFIRMED DIAGNOSIS OF INFECTION IN ASIAN ELEPHANTS () BY DECADES.

() infection was diagnosed in 16 human-managed Asian elephants () at four different US facilities. A retrospective review was performed to collate information on serological test results and describe the timelines from exposure to an elephant known to be positive for , detection of antimycobacterial antibodies in the exposed elephant, and isolation from the exposed elephant to confirm diagnosis. Seroconversion was defined by a positive test result using ElephantTB STAT-PAK, multiantigen print immunoassay, or DPP VetTB assay for elephants (Chembio Diagnostic Systems, Inc).

Comparing Medical Record Abstraction (MRA) error rates in an observational study to pooled rates identified in the data quality literature.

Background: Medical record abstraction (MRA) is a commonly used method for data collection in clinical research, but is prone to error, and the influence of quality control (QC) measures is seldom and inconsistently assessed during the course of a study. We employed a novel, standardized MRA-QC framework as part of an ongoing observational study in an effort to control MRA error rates. In order to assess the effectiveness of our framework, we compared our error rates against traditional MRA studies that had not reported using formalized MRA-QC methods.

SGLT2 inhibition alters substrate utilization and mitochondrial redox in healthy and failing rat hearts.

Previous studies highlight the potential for sodium-glucose cotransporter type 2 (SGLT2) inhibitors (SGLT2i) to exert cardioprotective effects in heart failure by increasing plasma ketones and shifting myocardial fuel utilization toward ketone oxidation. However, SGLT2i have multiple in vivo effects and the differential impact of SGLT2i treatment and ketone supplementation on cardiac metabolism remains unclear. Here, using gas chromatography-mass spectrometry (GC-MS) and liquid chromatography-tandem mass spectrometry (LC-MS/MS) methodology combined with infusions of [13C6]glucose or [13C4]βOHB, we demonstrate that acute SGLT2 inhibition with dapagliflozin shifts relative rates of myocardial mitochondrial metabolism toward ketone oxidation, decreasing pyruvate oxidation with little effect on fatty acid oxidation in awake rats.
