Introduction: Clinical trials have shown that liraglutide effectively lowers glycated hemoglobin A1c (A1C) levels in adult patients with type 2 diabetes (T2D). However, no studies have evaluated the effectiveness of liraglutide by body mass index (BMI) in the United States (US) in clinical practice. This study examined liraglutide's clinical effectiveness to lower A1C and body weight after 6 months in T2D patients stratified by baseline BMI.
Methods: This was a retrospective cohort study using the General Electric Centricity electronic medical records database. Adult patients with T2D (≥18 years and BMI≥ 25 kg/m(2)) and A1C >7% at baseline who started liraglutide between January 1, 2010 and January 31, 2013 and who did not use insulin or a glucagon-like peptide-1 analog 12 months before initiating liraglutide (N = 3,005) were selected. Changes from baseline, stratified by BMI, in A1C, body weight, A1C <7% goal attainment, and incidence of severe hypoglycemia at 6-month follow-up were examined.
Results: After 6 months, A1C levels decreased on average by 0.95%, 1.02%, 0.99%, and 0.84% for BMI categories 25.0-29.9 (n = 333), 30.0-34.9 (n = 793), 35.0-39.9 (n = 821), and ≥40.0 kg/m(2) (n = 1,058), respectively (P = 0.30). The proportions of patients achieving A1C <7% at 6 months were 38.2%, 37.0%, 40.9%, and 41.0% (P = 0.54). The absolute body weight decreased by 1.5 to 4.0 kg across BMI and the rate of severe hypoglycemia (0.2%) was low.
Conclusion: Patients with T2D experienced statistically significant decreases in A1C and body weight after initiating liraglutide regardless of their BMI. Liraglutide reduced A1C equally well across baseline BMI in clinical practice in the US.

Impact of Frailty on Antihypertensive Treatment in Older Adults.
Hypertension

The George Institute for Global Health, Faculty of Medicine, University of New South Wales, Newtown, Australia (L.C., S.Y., N.E., M.W., T.L., Y.G., C.S.A., K.H., X.C., R.P.).
Background: The association between systolic blood pressure and all-cause mortality differs between frail and nonfrail individuals, highlighting uncertainties about the effectiveness of antihypertensive treatments in frail populations.
Methods: Using data from the SHEP trial (Systolic Hypertension in the Elderly Program), a baseline frailty index (FI), including 55 variables, was constructed. Fine-Gray subdistribution hazard models and Cox proportional hazards regression models were used to explore the association between baseline FI and the risks of stroke, cardiovascular disease, and all-cause death, as well as to examine whether the impact of antihypertensive treatment on these outcomes was modified by baseline FI.
Early Versus Delayed Antihypertensive Treatment After Acute Ischemic Stroke by Hypertension History.

Department of Neurology, Beijing Tiantan Hospital, Capital Medical University, China. (X.X., X.L., Y.P., Yufei Wei, Y.J., M.W., J.J., X.M., Yilong Wang, Yongjun Wang, L.L.).
Background: We performed a prespecified subgroup analysis of the CATIS-2 trial (China Antihypertensive Trial in Acute Ischemic Stroke II) to compare the effect of early versus delayed antihypertensive treatment on death and disability in patients with and without medical history of hypertension.
Methods: CATIS-2 is a multicenter randomized clinical trial conducted in 106 hospitals in China. The trial randomized 4810 patients with acute ischemic stroke within 24 to 48 hours of symptom onset and elevated systolic blood pressure between 140 and <220 mm Hg to receive antihypertensive treatment immediately after randomization or to discontinue antihypertensive medications for 7 days and then receive treatment on day 8.

Hepatitis D virus (HDV) significantly influences the progression of liver diseases. Through clinical observations and database analyses, it has been established that patients coinfected with HDV and hepatitis B virus (HBV) experience accelerated progression toward cirrhosis, hepatocellular carcinoma (HCC), and liver failure compared to those infected solely with HBV. A higher viral load correlates with increased replicative activity, enhanced infectivity, and more severe disease manifestations.

Background: While premature ejaculation (PE) can be divided into lifelong PE (LPE), acquired PE, natural variable PE (NPE), and subjective PE (SPE), there is no objective method to classify PE.
Aim: To determine the value of serum serotonin (5-HT), leptin, and norepinephrine (NE) levels in the classification of PE.
Methods: From July 2023 to July 2024, we recruited 150 participants and divided them into 4 groups: LPE (43 cases), NPE (32 cases), SPE (35 cases), and non-PE (40 cases) groups.
Endoscopic injection sclerotherapy (EIS) is a useful prophylactic hemostatic procedure for esophageal varices. However, injecting sclerosing agents into blood vessels is technically challenging and often ineffective. Gel-immersion EIS (GI-EIS) may facilitate easier intravascular sclerosing agent injection by dilating the varices and enhancing scope stability by maintaining low intra-gastrointestinal pressure.
