Abstract

Background: The prevalence of GERD has increased in all age groups with the highest incidence in the age group of 20 to 45 years. Bank employees are in the reproductive age group who have time demands of work, which require longer working hours with lifestyle changes and are at risk of developing GERD. Changes in eating patterns with spicy, sour and fatty foods such as corn bose, sei meat, sambal luat and tangerine soe if consumed frequently and in excessive amounts can cause heartburn and regurgitation complaints.Methods: This study uses an analytical observational research design with a cross sectional design conducted on bank employees in Soe City, East Nusa Tenggara using a local culinary diet questionnaire and a gastroesophageal reflux disease questionnaire (GERD-Q). Sampling using total sampling technique and obtained 99 research subjects who meet the inclusion criteria.Results: From the results of the contingency coefficient test, there is no relationship between local culinary eating patterns with GERD symptoms in bank employees in Soe City, East Nusa Tenggara.Conclusion: there is no correlation between local culinary eating patterns with GERD symptoms in bank employees in Soe City, East Nusa Tenggara.

Abstract

Central obesity and hypertension are major public health problems contributing substantially to the burden of non-communicable diseases. Excess saturated fat intake plays an important role in visceral fat accumulation and blood pressure elevation, particularly in populations with distinctive lifestyles and dietary patterns such as religious communities and monasteries. This study aimed to determine the association between saturated fat intake and central obesity as well as elevated hypertension among members of communities and monasteries of the Archdiocese of Ende. An observational analytic study with a cross-sectional design was conducted. A total of 50 respondents were selected using simple random sampling. Saturated fat intake was assessed using a Semi-Quantitative Food Frequency Questionnaire, central obesity was determined by waist circumference measurement, and elevated hypertension was identified through blood pressure assessment. Data were analyzed using the Chi-Square test with a significance level of α = 0.05. Most respondents had normal saturated fat intake (50.0%), followed by high intake (40.0%). Central obesity was observed in 72.0% of respondents, and 40.0% were classified as having elevated hypertension. Bivariate analysis demonstrated a significant association between saturated fat intake and central obesity (p = 0.001) as well as elevated hypertension (p = 0.009). There is a significant association between saturated fat intake and both central obesity and elevated hypertension among members of communities and monasteries of the Archdiocese of Ende.

Abstract

Propionibacterium acnes is a type of bacteria that typically exists on skin areas with many sebaceous glands, like the scalp and face. The exploration of natural antibacterial agents made from herbal plants is one approach to decrease resistance issues. One such plant utilized is red betel, scientifically known as Piper crocatum. The objective of this study is to assess the antibacterial properties of the ethanol extract from red betel leaves against Propionibacterium acnes. This study adopted a true experimental framework with a post-test only control group model. The red betel leaf extract was produced through maceration using a 70% ethanol solution, followed by evaporation until a concentrated extract was achieved. In this study, the treated groups included various concentrations: 100%, 50%, 25%, 12.5%, 6.25%, 3.125%, and 1.56%, alongside a positive control using clindamycin and a negative control using sterile aquades. The antibacterial testing was performed using the disc diffusion method, referred to as the Kirby-Bauer technique against Propionibacterium acnes bacteria. The analysis conducted was the One Way Anova statistical test. Findings from this study reveal that the extract of red betel leaves contains alkaloids, tannins, saponins, flavonoids, and terpenoids. The testing outcomes indicate that the average diameter of the inhibition zone resultant from each sample is 11.16 mm for the 100% concentration, 9.63 mm for the 50% concentration, 8.85 mm for the 25% concentration, 8.21 mm for the 12.5% concentration, 7.78 mm for the 6.25% concentration, 6.93 mm for the 3.125% concentration, and 0 mm for the 1.56% concentration. From the results, it can be concluded that the ethanol extract from red betel leaves exhibits antibacterial activity against the growth of Propionibacterium acnes.
