Introduction: The presence of metabolic abnormalities in patients with type 2 diabetes (T2D) increases the risk of cardiovascular disease and other comorbidities. This analysis compared the effects of tirzepatide (5, 10, and 15 mg) and dulaglutide 0.75 mg on the prevalence of metabolic abnormalities in Japanese patients with T2D.
Methods: This was a post hoc analysis of SURPASS J-mono, a multicenter, randomized, double-blind, active-controlled, parallel-group, phase 3 trial that compared the efficacy and safety of tirzepatide monotherapy (5, 10, and 15 mg) to dulaglutide 0.75 mg in Japanese patients with T2D. Thresholds for abnormalities were based on the Japanese criteria for metabolic syndrome. Proportions of participants meeting a composite endpoint (visceral fat accumulation measured by waist circumference plus two or more of dyslipidemia, hypertension, or hyperglycemia) or individual component thresholds were calculated at baseline and week 52 for the overall population and for baseline body mass index (BMI) subgroups (< 25, 25 to < 30, and ≥ 30 kg/m).
Results: Of 636 randomized participants, 431 (67.8%) met the composite endpoint at baseline, with similar findings observed across treatment arms. At week 52, the proportion of participants on treatment that met the composite endpoint was 31.7%, 23.0%, and 14.2% in the tirzepatide 5-, 10-, and 15-mg arms, respectively, and 56.5% in the dulaglutide arm (p < 0.001). A higher proportion met the composite endpoint at baseline in the BMI 25 to < 30 and ≥ 30 kg/m subgroups (73.2-79.3%) compared with the < 25 kg/m subgroup (45.3%), with reductions observed across all BMI subgroups treated with tirzepatide. The proportion of participants with individual metabolic abnormalities showed similar trends to those observed for the composite endpoint. Tirzepatide was consistently superior to dulaglutide across all assessments.
Conclusions: Tirzepatide reduced the prevalence of multiple metabolic abnormalities, indicating tirzepatide may have metabolic benefit in Japanese patients with T2D.

Major depressive disorder (MDD) is usually considered associate with immune inflammation and synaptic injury within specific brain regions. However, the molecular mechanisms underlying the neural deterioration resulting in depression remain unclear. Here, it is found that miR-204-5p is markedly downregulated in the ventromedial prefrontal cortex (vmPFC) in a chronic unpredictable mild stress (CUMS) induce rat model of depression.

Identifying the prolactin threshold that necessitates pituitary magnetic resonance imaging (MRI) in patients with hyperprolactinemia remains challenging. Therefore, developing standards for serum prolactin level criteria to predict prolactinoma is critical. This study aimed to investigate the correlation between hyperprolactinemia and the presence of pituitary adenoma among Saudi female patients with verified prolactin levels.

A hallmark of chronic and inflammatory diseases is the formation of a fibrotic and stiff extracellular matrix (ECM), typically associated with abnormal, leaky microvascular capillaries. Mechanisms explaining how the microvasculature responds to ECM alterations remain unknown. Here, we used a microphysiological model of capillaries on a chip mimicking the characteristics of healthy or fibrotic collagen to test the hypothesis that perivascular cells mediate the response of vascular capillaries to mechanical and structural changes in the human ECM.

Pregnancy complications pose challenges for both pregnant women and obstetricians globally, with the pathogenesis of many remaining poorly understood. Recently coined as a mode of cell death, cuproptosis has been proposed but remains largely unexplored. This process involves copper overload, resulting in the accumulation of fatty acylated proteins and subsequent loss of iron-sulfur cluster proteins.
