Purpose: Youth with type 1 diabetes mellitus (T1DM) are at risk of cardiovascular disease (CVD). We evaluated if metformin or statin use was associated with surrogate measures of improved CVD.
Methods: We included participants from the SEARCH observational study. Participants treated with insulin plus metformin (n=42) or insulin plus statin (n=39) were matched with 84 and 78 participants, respectively, treated with insulin alone. Measures of arterial stiffness obtained were pulse wave velocity (PWV), augmentation index (AI75), and heart rate variability as standard deviation of the normal-to-normal interval (SDNN) and root mean square differences of successive NN intervals (RMSSD).
Results: CVD measures were not significantly different among participants on insulin plus metformin versus those on insulin alone: PWV (5.9±1.0 m/sec vs. 5.8±1.5 m/sec, P=0.730), AI75 (1.8 [-6.0 to 8.0] vs. -2.4 [-10.7 to 3.8], P=0.157), SDNN (52.4 [36.8-71.1] m/sec vs. 51.8 [40.1-74.9] m/sec, P=0.592), and RMSSD (43.2 [29.4-67.6] vs. 47.4 [28.0-76.3], P=0.952). CVD measures were not different for statin users versus nonusers: PWV (5.7±0.8 m/sec vs. 5.9 ±1.1 m/sec, P=0.184), AI75 ( -4.0 [-9.5 to 1.7] vs. -6.7 [-11.3 to 5.7], P=0.998), SDNN (54.6 [43.5-77.2] m/sec vs. 63.1 [44.2-86.6] m/sec, P=0.369), and RMSSD (49.5 [31.2-74.8] vs. 59.2 [38.3-86.3], P=0.430).
Conclusion: We found no associations of statin or metformin use with surrogate measures of CVD. Future prospective pediatric clinical trials could address this issue.

Background: Serum copeptin (sCoP) is used as a surrogate for plasma arginine vasopressin (pAVP) measurement in humans.
Objective: To measure pAVP and sCoP at rest and after osmotic- and non-osmotic stimulation testing in dogs.
Animals: Eight young castrated/spayed healthy research Beagles, eight young intact dogs, and eight old neutered healthy client-owned dogs.

Diagnostic bones can aid in identification and size determination of fishes from ingested prey, archaeological remains or damaged specimens. We extracted diagnostic structures, including cleithra, dentaries, opercles and otoliths, from juvenile spring Chinook salmon (Oncorhynchus tshawytscha) from three distinct groups: hatchery, naturally produced and surrogate, representing shared genetics. Although our observations highlight that growth and life history are important considerations in structuring allometry, we note that a wide variety of diagnostic bones and measurement axes may be suitable for determining body lengths where remains may be damaged or incomplete.

Background: Targeted bottom-up proteomics is of great interest for the straightforward, accurate, and sensitive measurement of specific protein biomarkers from surrogate peptide fragments. However, this approach typically relies on off-line enzymatic digestion with trypsin, a time-consuming step that may be inadequate for covering certain sequence regions containing important post-translational modifications (PTMs).
Results: In this study, we present an in-line enzymatic digestion strategy for the targeted bottom-up analysis of α-synuclein (α-syn), which is a protein biomarker of Parkinson's disease (PD).

Background: Carotid artery stenosis prevalence increases with age, and carotid endarterectomy (CEA) is a possible treatment option. However, nonagenarians are at high risk of experiencing postoperative complications and are often not considered surgical candidates. We aimed to identify risk factors associated with postoperative myocardial infarction (MI), stroke, and death within 30 days for nonagenarians undergoing CEA and to analyze the predictive ability of modified frailty indices (mFI) in predicting adverse outcomes for this population.

The use of cementless total knee arthroplasty (TKA) has significantly increased over the past decade. However, there is no objective criteria or consensus on parameters for patient selection for cementless TKA. The purpose of this study was to develop a machine learning model based on patient and radiographic parameters that could identify patients indicated for cementless TKA.
