Adult male rats were fed a liquid diet providing 35% of the calories as ethanol, while pair-fed controls received the corresponding diet with alcohol replaced by an equicaloric concentration of sucrose. After 1 month, lactate/pyruvate (L/P) and beta-hydroxybutyrate/acetoacetate (beta-HB/AcAc) ratios in the livers were determined under five different conditions: (1) both diets present up to the time of sacrifice, (2) ethanol diet replaced by control diet for 24 h before sacrifice, (3) ethanol diet replaced by control diet for 48 h before sacrifice, (4) as in the preceding, followed by intraperitoneal (i.p.) injection of ethanol, 1 g/kg, 1 h before sacrifice, (5) as in the preceding, but i.p. injection 3 h before sacrifice. The L/P ratio was significantly higher in the alcohol group than in controls under the first experimental condition, but the groups did not differ under the other four conditions. The beta-HB/AcAc ratio was also significantly higher in the alcohol group under the first condition. This difference disappeared in the second and third conditions. Under the fourth and fifth conditions the beta-HB/AcAc ratio was significantly higher in the controls. The results are compatible with an adaptive increase in mitochondrial reoxidation of NADH in the chronic alcohol groups, but the possibility of a change due to alcohol withdrawal can not be excluded.

Efficacy and Safety of Aldosterone Synthase Inhibitors for Hypertension: A Meta-Analysis of Randomized Controlled Trials and Systematic Review.
Hypertension
January 2025
Department of Medicine, Unit of Internal Medicine B, University of Verona School of Medicine, Azienda Ospedaliera Universitaria Integrata Verona, Policlinico G.B. Rossi, Italy.
Background: Hypertension is a major global health issue. Aldosterone synthase inhibitors (ASIs) have emerged as a promising therapeutic strategy for blood pressure control.
Methods: A thorough search of the MEDLINE and Embase databases up to March 30, 2024, identified randomized trials comparing ASIs with a placebo for hypertension treatment.
Long-Term Prognostic Implications of Non-Culprit Lesions in Patients Presenting With an Acute Myocardial Infarction: Is It the Angiographic Stenosis Severity or the Underlying High-Risk Morphology?
Circulation
January 2025
Department of Cardiology, The 2nd Affiliated Hospital of Harbin Medical University, Harbin, China (J.D., J.Z., X.X., Y.C., S.S., S.L., L.C., Y.W., L.L., R.G., D.H., X.M., R.Z., H.Y., T.C., J.T., X.L., S.J., J.H., C.F.B.Y.).
Background: Patients with acute myocardial infarction and angiographically obstructive non-culprit lesions are at high risk for recurrent major adverse cardiac events (MACEs). However, it remains largely unknown whether events are due to stenosis severity or due to the underlying high-risk lesion morphology.
Methods: Between January 2017 and December 2021, 1312 patients with acute myocardial infarction underwent optical coherence tomography of all the 3 main epicardial arteries after successful percutaneous coronary intervention.
Shifting tides: A survey analysis of urologists' evolving attitudes toward focal therapy for prostate cancer.
Indian J Urol
January 2025
Section of Urology, Department of Surgery, University of Chicago, Chicago, IL, USA.
Introduction: Focal therapy (FT) is emerging as an alternative to radical treatment for prostate cancer (CaP). The purpose of this study is to assess the current perceptions of FT amongst urologists.
Methods: A 22-item questionnaire was e-mailed to members of the American Urological Association.
Management and Outcomes of Type I and Type II Myocardial Infarction in Cardiogenic Shock.
CJC Open
February 2024
CAPITAL Research Group, University of Ottawa Heart Institute, Ottawa, Ontario, Canada.
Background: Type I myocardial infarction (T1MI) or type II myocardial infarction (T2MI) have different underlying mechanisms; however, in the setting of cardiogenic shock (CS), it is not understood if patients experience resultantly different outcomes. The objective of this study was to determine clinical features, biomarker patterns, and outcomes in these subgroups.
Methods: Patients from the CAPITAL-DOREMI trial presenting with acute myocardial infarction-associated CS (n = 103) were classified as T1MI (n = 61) or T2MI (n = 42).
Press-Fit Bone-Anchored Prosthesis for Individuals with Transtibial Amputation.
JBJS Essent Surg Tech
May 2024
Radboud University Medical Center, Nijmegen, The Netherlands.
Background: This video article describes the use of bone-anchored prostheses for patients with transtibial amputations, most often resulting from trauma, infection, or dysvascular disease. Large studies have shown that about half of all patients with a socket-suspended artificial limb experience limited mobility and limited prosthesis use because of socket-related problems. These problems occur at the socket-residual limb interface as a result of a painful and unstable connection, leading to an asymmetrical gait and subsequent pelvic and back pain.
