Long-term safety and efficacy of pemafibrate once-daily extended-release (XR) tablets, taken in morning or evening, were evaluated dyslipidemic patients with high triglycerides (TG). In this multicenter, randomized, open-label, parallel-group, phase 3 long-term study, TG randomly assigned to evening administration XR for 52 weeks. The dose was started at 0.2 mg/day increased 0.4 having fasting serum ≥ 150mg/dL during treatment. primary endpoint percent change TG. study enrolled 121 patients,...

Aims: Pemafibrate, a selective peroxisome proliferator-activated receptor α modulator that lowers serum triglyceride levels and increases high-density lipoprotein cholesterol levels, is approved for treating dyslipidemia as twice-daily immediate-release (IR) tablets. A once-daily extended-release (XR) tablet has also been developed. We aimed to confirm the non-inferiority of XR (0.2 or 0.4 mg/day; once daily) IR twice in lowering patients with hypertriglyceridemia.

Triple-negative breast cancer (TNBC) is negative for hormone receptors and human epidermal growth factor receptor 2 (HER2). In stage I TNBC, adjuvant therapy or follow-up are performed according to risk factors, but clinical trial data scarce. recent years, it has been reported that HER2-low cases (1+/2+ in situ hybridization negative) have different prognoses than HER2-0 cases. However, the of recurrence factors this population TNBC not yet investigated.Herein, out 174 patients with who...

Abstract Introduction Burns can cause serious physical injury and psychosocial distress. Extremes of body weight also result in impaired recovery emotional However, the impact BMI on long-term self-reported outcomes is not well understood. We aimed to compare long-term, functional among adult burn survivors who were obese, normal weight, underweight at discharge. Methods Adult participating a national longitudinal, multicenter patient-reported database between 2015-2023 included....

Various preinjury factors a history depression anxiety are also associated with impaired long-term recovery. One social factor that has not been well studied pre-injury employment status on patient-reported outcomes post-injury. Understanding the longitudinal health impact critical to improving public In this study, we...

Abstract Introduction Stigma is defined as when someone treated negatively or devalued due to a particular characteristic attribute. People with physical appearances that differ from the expected, such individuals burn injury, are at risk for stigmatization. This may influence quality of life and can lead social isolation. Therefore, this study aims examine stigma its predictors in population. Methods Adult survivors multicenter longitudinal database 2015-24 were examined. The primary...

Abstract Background: Ovarian clear cell carcinoma (OCCC) is a rare subtype of ovarian cancer, with higher incidence in East Asia compared to Western countries and tendency affect younger individuals. OCCC has poor prognosis due its low sensitivity chemotherapy, presenting significant unmet medical need. However, therapeutic development been limited rarity. Recently, advancements antibody-drug conjugates (ADCs) targeting Trophoblastic cell-surface marker (TROP2) have shown promise, but the...

Abstract Prognostic value of hematologic indices and their association with the tumor microenvironment (TME) remain unclear in advanced soft tissue sarcoma (STS). We aimed to evaluate prognostic correlation TME status STS treated first-line doxorubicin (DXR) therapy. Clinical data three hematological indices, including lymphocyte-to-monocyte ratio (LMR), platelet-to-lymphocyte ratio, neutrophil-to-lymphocyte were collected from 149 patients STS. The was pathologically examined by CD3, CD68,...

Abstract Purpose Stromal tumor-infiltrating lymphocytes (TILs) are independent prognostic factors in systemically untreated early-stage triple-negative breast cancer (TNBC). Other immune biomarkers including CD8, CD20, programmed cell death-ligand 1 (PD-L1), and tertiary lymphoid structures (TLS) also reported to be associated with prognosis. However, whether combining other TILs would allow for further stratification is unknown. Methods We retrospectively analyzed 125 patients TNBC not...
