Fermentation of fruits offers a diverse range of flavors, smells, and colors. Colored fruits are rich in naturally occurring pigments, such as betacyanin. Hence, they are considered to possess ...powerful antioxidant activities. However, in wine production, such pigments often diversify the flavor and color of the wine. The objective of this study was to compare the quality of two types of wines: a single‐fruit (pitaya) wine and a mixed‐fruit wine that contains watermelon (Citrullus lanatus), mint (Mintha spicata), and pitaya (Hylocereus costaricensis). In this study, fresh pitaya, watermelon, and mint leaves were fermented using Saccharomyces cerevisiae. Juice extracts underwent fermentation at room temperature for 7 days under dark conditions. Physicochemical changes, such as pH, sugar content, specific gravity, and alcohol content, were observed daily. The antioxidant activities were measured by the 2,2‐diphenyl‐1‐picrylhydrazyl (DPPH) assay, the ferric reducing antioxidant power (FRAP) assay, and total phenolic contents (TPCs). After 14 days of fermentation, the alcohol contents of mixed and pitaya wine were 11.22% (v/v) and 11.25%, respectively. The total sugar content of the mixed wine was 8.0 °Brix, while that of pitaya wine was 7.0 °Brix. Moreover, pitaya wine exhibited a higher TPC (22.7 mg GAE/100 g D.W.), and better FRAP (3578 μmole/L) and DPPH scavenging ability (80.2%) compared to the mixed wine with a TPC of 21.4 mg GAE/100 g D.W., FRAP of 2528 μmole/L, and DPPH of 75.6%., while the addition of watermelon and mint did not change the alcohol percentage contents of wine.
This is the first paper to demonstrate the anti‐oxidative ability and sensory evaluation in different types of pitaya wines.

Introduction: Postoperative bleeding is a significant complication following cardiac surgery, with a global re-exploration incidence of 2-5%. This study aims to investigate re-exploration rates, risk ...factors, and outcomes within the unique context of a tertiary care center in Nepal. Methods: In this retrospective, single-center study, we analyzed all consecutive adult patients (≥18 years) who underwent cardiac surgery with cardiopulmonary bypass (CPB) at the Manmohan Cardiothoracic Vascular and Transplant Centre (Nepal) between 2018-2021. Data on demographics, clinical characteristics, operative details, re-exploration, and outcomes were extracted from medical records. Statistical analysis included descriptive statistics, chi-square tests, independent samples t-tests, and logistic regression. Results: Of 720 patients, 56 (7.8%) required re-exploration for bleeding. Emergency procedures were strongly associated with higher re-exploration (p<0.05). Non-surgical bleeding was the primary cause in 42.9% of cases. Independent risk factors included preoperative deranged LFTs (OR=2.1, 95% CI: 1.2-3.7), elevated creatinine (>1.5 mg/dL, OR= 3.2, 95% CI: 1.8-5.6), prolonged CPB time (>120 min), and substantial transfusion requirements. Modified Bentall's procedures had the highest re-exploration rate (21.4%). Re-explored patients experienced higher AKI rates (87.5%), longer hospitalizations (13.6 vs. 7.2 days, p<0.001), and increased in-hospital mortality confined to emergency cases (1.94%). Conclusion: Emergency procedures had higher rate of re-exploration. Preoperative deranged LFTs, elevated creatinine, prolonged CPB time, and substantial transfusion requirements were independent risk factors for re-exploration. Re-explored cases experienced higher complication. In-hospital mortality were confined to emergency cases only.
