Abstract

The incidence of antifungal resistance to Candida albicans infections has been growing over the past years; therefore, innovations are required to develop medicinal plants with antifungal properties such as durian fruit peels (Durio zibethinus Murray) that contain significant of bioactive compounds with antifungal properties. The aim of this study was to determine the antifungal activity of D. zibethinus fruit peel extract against C. albicans by analyzing the minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC). A post-test only control group experiment was conducted from July to October 2020. D. zibethinus peel was collected from Simalungun Regency, Medan, Indonesia, and extracted by maceration technique using 70% ethanol to obtain D. zibethinus peel ethanol extract (DPEE). Samples of C. albicans were obtained from the Laboratory of Microbiology, Faculty of Medicine, Universitas Sumatera Utara, Medan, Indonesia. The diffusion method was used to determine the antifungal activity. Six groups with different concentrations of DPEE (6.25%, 12.5%, 25%, and 50%), ketoconazole (positive control) and dimethyl sulfoxide (negative control) were exposed to C. albicans in six replicates. Six lower concentrations (12.5%, 6.25%, 3.12%, 3%, 1.56%, and 0.78%) were divided to perform the liquid dilution method to obtain the MIC and affirmation test for MBC. The diameter of the inhibition zone was analyzed using one-way ANOVA and the Tukey post-hoc test for differences between concentrations. Our data indicated that the DPEE 6.25% had the largest inhibition zone (17.26±5.64 mm) and the inhibition zones were significant different among concentrations of DPEE (p<0.05). Furthermore, the DPEE had a MIC of 0.78% and MBC of 3.125% against C. albicans. This study highlights that the ethanol extract of D. zibethinus has potential antifungal activity against C. albicans. However, a further study is needed to determine its antifungal activities in more precise manner.

Abstract

Respiratory droplets, naturally produced during expiration, can transmit pathogens from infected individuals. Wearing a face mask is crucial to prevent such transmission, yet the perception of dyspnea and uncomfortable breathing remains a common concern, particularly during epidemics. The aim of this study was to investigate the impact of face mask use on the perception of dyspnea, cardiopulmonary parameters, and facial temperature during physical activity. A randomized crossover study was conducted on healthy adults at a physiology laboratory located in the Faculty of Medicine, Universitas Sumatera Utara, Medan, Indonesia, in November 2022. Participants underwent five stages of physical exercise tests based on the Bruce Protocol under three conditions: without any face mask (control), wearing a surgical mask, and an N95 mask, forming the study's main groups. Dyspnea perception (measured by the Modified Borg Dyspnea Scale), cardiopulmonary parameters (heart rate, oxygen saturation, respiratory rate, blood pressure, and mean arterial pressure) and facial temperature were measured before the exercise test (pre-workout), at the end of stage 1, 2, 3, 4, 5, and after the whole exercise test (post-workout). A two-way repeated measures ANOVA was conducted, considering two factors: the type of mask (control, surgical mask, N95 mask) and the various stages of the exercise test. A total of 36 healthy adults were included in the study. We found that dyspnea perception was much worse in the N95 mask group, particularly during vigorous exercise. There was no significant difference between groups in cardiopulmonary parameters. However, participants wearing N95 had a greater supralabial temperature than those wearing surgical masks or no mask at all. It is recommended to undertake a more in-depth evaluation of cardiopulmonary physiological measures.

Abstract

Postmenopausal women often experience hormonal changes and shifts in fat composition, affecting weight gain and obesity. Understanding the link between hormones, especially estrogen and leptin, is key to managing weight and lowering disease risk in menopausal women. The aim of this study was to compare the levels of leptin and estrone in menopausal women with normal weight and obesity. A cross-sectional study was conducted on menopausal women, either normal body mass index (BMI) or obese, at H. Adam Malik General Hospital, Medan, Indonesia. Blood samples were collected to measure leptin and estrone levels using the enzyme-linked immunosorbent assay (ELISA) method. The differences in leptin levels between groups were analyzed using the Wilcoxon test, while the correlation between BMI and leptin was examined using the Pearson correlation test. The disparity in estrone levels in both groups was analyzed using the Mann-Whitney test and the correlations between variables were assessed using the Spearman or Pearson correlation tests as appropriate. The mean leptin levels in normal BMI and obesity groups were 17.73±4.96 and 25.46±12.95 ng/mL, respectively, and were statistically different (p=0.006). The mean estrone levels in menopausal women with normal BMI and obesity were 943.23±391.79 and 851.38±282.23 ng/mol, respectively and were not statistically different (p=0.564). A significant positive correlation was found between BMI and leptin level (r=0.59; p<0.001), while  BMI and estrone were not significantly correlated (r=0.083; p=0.559). In conclusion, leptin level was significantly different between BMI groups and had a strong positive correlation with BMI. This finding could be an important insight in body weight management and disease risk prevention in menopausal women.
