In addition to well-known side effects such as rash, redness, and bone resorption, unexpected facial complications may occasionally occur several years after certain medical procedures. This report presents rare cases of orofacialsymptoms that developed as delayed responses to cosmetic filler injections. Three separate patients presented to theauthors’ institution with varying severities of orofacial symptoms. These symptoms, initially diagnosed clinically asinflammation or neoplasms of the parotid gland, were later identified through magnetic resonance imaging as diseases potentially associated with filler materials injected approximately 4-8 years earlier. The primary goal of this report was to inform specialists in the oral and maxillofacial field about the possibility of such complications, enabling them tomanage patient symptoms effectively and develop appropriate treatment strategies.

Objective: To compare coronary artery dimension-adjusted subtended myocardial mass between patients with hypertrophic cardiomyopathy (HCM) and a normal population without detectable atherosclerosis, and between HCM patients with and without chest pain. Materials and Methods: Twenty-five patients with HCM but no detectable atherosclerosis on coronary computed tomography angiography (CCTA) were included in the study. This group comprised 14 patients with chest pain and 11 patients without chest pain. They were matched with 25 healthy participants based on sex, age, coronary dominance pattern, and body surface area. The minimal lumen area (MLA) and subtended myocardial volume (V sub) were assessed in the left main (LM), proximal left anterior descending (pLAD), proximal left circumflex (pLCx), and proximal right coronary (pRCA) arteries. Additionally, an index of the subtended myocardial mass adjusted for the MLA, calculated as V sub/MLA 2 , was determined. Results: MLA was significantly larger in patients with HCM compared to the control group in LM (20.93 ± 6.31 mm 2 vs.15.24 ± 3.90 mm 2 , P< 0.001), pLAD (14.28 ± 3.55 mm 2 vs. 11.36 ± 2.07 mm 2, P = 0.001), pLCx (10.94 ± 3.60 mm 2 vs. 9.15 ± 2.93 mm 2 , P = 0.045), and pRCA (13.41 ± 4.85 mm 2 vs. 11.22 ± 3.20 mm 2 , P = 0.018). Despite an increase in coronary luminal area, patients with HCM exhibited significantly higher V sub/MLA 2 compared to the control group in both the pLAD (403.56 ± 200.35 mm -1 vs. 241.70 ± 85.87 mm -1 , P < 0.001) and the pRCA (186.06 ± 95.07 mm -1 vs. 125.07 ± 70.18 mm -1 , P= 0.007). V sub/MLA 2 was significantly elevated in patients with chest pain compared to those without in the pLAD (473.75 ± 227.38 mm -1 vs. 314.24 ± 110.74 mm -1 , P = 0.018) and the pLCx (417.04 ± 182.65 mm -1 vs. 275.29 ± 112.97 mm -1 , P = 0.044). Conclusion CCTA-derived V sub/MLA 2 may more accurately reflect the balance between myocardial blood supply and demand, offering insights into the occurrence of demand angina in patients with HCM without obstructive coronary artery disease.

Hangovers from alcohol consumption cause symptoms like headaches, nausea, and fatigue, disrupting daily activities and overall well-being. Over time, they can also lead to inflammation and oxidative stress. Effective hangover relief alleviates symptoms, prevents dehydration, and replenishes energy needed for daily tasks. Natural foods considered high in antioxidants and antiinflammatory properties may aid in the hepatic breakdown of alcohol. The study aims to investigate the impact of glutathione or its enriched yeast extract, which is recognized for its antioxidant characteristics, on alcohol metabolism and alleviating hangovers in a rat model exposed to binge drinking. In this study, glutathione and its enriched yeast extract controlled hangover behaviour patterns, including locomotor activity. Additionally, it enhanced the activities of alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH) following ethanol ingestion (3 g/kg). Further, the incorporation of glutathione led to an increase in the expression of antioxidant enzymes, such as SOD and catalase, by activating the nuclear erythroid 2-related factor 2 (Nrf2) signaling pathway.This activation reduced the excessive production of reactive oxygen species (ROS) and malondialdehyde. Next, glutathione modulated the activity of cytochrome P450 2E1 (CYP2E1) and the protein expressions of Bax and Bcl2. Besides, in vitro and in vivo investigations with glutathione demonstrated a regulating effect on the pan-s-glutathionylation and its associated protein expression, glutaredoxin 1 (Grx1), glutathione-S-transferase Pi (GST-π), and glutathione reductase (GR). Together, these findings suggest that glutathione or its enriched yeast extract as a beneficial dietary supplement for alleviating hangover symptoms by enhancing alcohol metabolism and its associated Nrf2/Keap1 signalings.

Purpose: Apixaban is recommended for patients with atrial fibrillation. Although routine monitoring of plasma concentrations is not typically advised, factors such as ethnicity, sex, and comorbidities can influence these levels. Our study analyzed the plasma apixaban concentrations (PAC) in patients to explore whether these levels, along with underlying conditions, offer enhanced insights for risk stratification. Methods: This study analyzed 49 patients with atrial fibrillation who had been taking apixaban for over a month, examined factor Xa levels within 6 h post-administration, and correlated PAC with clinical characteristics such as age, body weight, estimated glomerular filtration rate (eGFR), presence of heart failure, and bleeding events. Results: The mean plasma concentration of apixaban in all patients was 160.3 ± 77.5 ng/mL. Those taking apixaban 5 mg twice daily had higher plasma concentrations than those taking 2.5 mg twice daily (191.2 ± 75.3 ng/mL vs.137.2 ± 72.0 ng/mL, p = 0.014). Among the patients receiving a reduced dose, renal function and heart failure were significantly associated with plasma concentrations. No factors were associated with the plasma concentrations in patients receiving the standard dose. Notably, reduced-dose patients with heart failure had plasma concentrations comparable to those of individuals receiving the standard dose and exhibited a higher incidence of bleeding than the other groups. Conclusions PAC measurement revealed that apixaban dosages, classified based on age, body weight, and eGFR, were generally effective. Nonetheless, heart failure may increase plasma levels and correlate with an increased bleeding risk in Korean patients on reduced doses. Therefore, tailoring apixaban prescriptions to account for heart failure and other comorbidities may enhance treatment efficacy.
