<![CDATA[Exposure to traumatic experiences during childhood can cause long-term adverse effects on an individual's psychological and neurobiological development. Psychosis as a severe psychiatric condition characterized by reality distortion often first emerges during adolescent development. This study was conducted using a systematic literature review method through analysis of relevant research articles published between 2015 and 2024. Based on literature analysis, adolescents with a history of childhood trauma show increased vulnerability to psychotic disorders through various mechanisms. Neurobiologically, complex trauma affects the dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis, triggers structural brain changes such as reduced hippocampal volume and amygdala enlargement, and disrupts neurotransmitter system balance. From psychological aspects, the formation of maladaptive cognitive schemas, memory disintegration, and deficits in social cognition also contribute to the emergence of psychotic symptoms. This review concludes that there is a significant relationship between past traumatic exposure and increased risk of psychotic disorders in adolescent populations, with a relationship pattern showing dose-response characteristics.]]>

<![CDATA[HIV/AIDS remains a global public health problem and has a significant impact on adolescents. During this phase, adolescents are vulnerable to risky behaviors that can increase the chance of HIV/AIDS transmission. One psychosocial factor that plays a crucial role in shaping preventive behavior is self-efficacy, which is an individual's belief in their ability to consistently take preventive measures. Low self-efficacy can hinder adolescents from optimally adopting HIV/AIDS preventive behaviors. Therefore, this study aims to analyze the relationship between self-efficacy and HIV/AIDS preventive behaviors among adolescents at SMAN 5, Jambi City.This study used a correlational design with a cross-sectional approach. A sample of 98 respondents was obtained through total sampling. Data collection was conducted using the Self-Efficacy Assessment in HIV Risk Behavior Prevention (EDP2B-HIV) questionnaire and the Sexual Behavioral Abstinence HIV/AIDS Questionnaire (SBAHAQ). Bivariate data analysis was performed using the Gamma correlation test to determine the relationship between self-efficacy and HIV/AIDS preventive behaviors. Univariate analysis showed that the majority of respondents had moderate levels of self-efficacy (71 respondents (71.4%), and moderate levels of HIV/AIDS prevention behavior (48 respondents (48.0%). Bivariate analysis showed a significant relationship between self-efficacy and HIV/AIDS prevention behavior in adolescents (p-value = 0.003; r = 0.551). This finding indicates that the higher the level of self-efficacy in adolescents, the better the HIV/AIDS prevention behavior they implement.Self-efficacy plays a crucial role in shaping and enhancing HIV/AIDS prevention behavior in adolescents. Adolescents with higher levels of self-efficacy tend to demonstrate better and more consistent prevention behavior.]]>

<![CDATA[Dental caries is the most prevalent oral health problem in Indonesia. Caries occurs due to bacterial colonization, primarily by Streptococcus mutans. Prevention of dental caries can be achieved by utilizing gambier (Uncaria gambier, Roxb) as an antimicrobial agent in the form of chewing gum combined with xylitol. This study aimed to develop an innovative bioactive formulation of gambier gum and to determine its effectiveness in reducing Streptococcus mutans colony counts and increasing salivary pH, both of which play roles in improving oral health and hygiene. This experimental study was conducted at the Biomedical Laboratory, Faculty of Medicine, Universitas Negeri Padang, from July to October 2025. Three formulations of gambier gum containing catechin concentrations of 0%, 70%, and 95% were tested for effectiveness by mixing them with participants’ saliva samples. The results showed a reduction in Streptococcus mutans colony counts compared to the control. Culture results of gambier gum with 0%, 70%, and 95% catechin demonstrated reductions of 40%, 60%, and 100%, respectively, relative to the control colonies. pH measurements indicated that gambier gum with 95% catechin prevented the saliva from becoming acidic. The gambier gum formulation containing 95% catechin exhibited the greatest antimicrobial effectiveness.]]>

<![CDATA[The safety of fruits and vegetables is important to prevent diseases caused by contamination by pathogenic microbes such as Escherichia coli and Staphylococcus aureus. This study aims to formulate and test the antimicrobial activity of effervescent effervescentes based on lime (Citrus aurantifolia) and tamarind (Tamarindus indica) peel extracts as natural decontaminants. The study was conducted experimentally with a post-test only design in the Integrated Laboratory and Biomedical Laboratory of the Faculty of Medicine, Padang State University. Effervescent tablets were made by the wet effervescentation method using three variations of extract concentrations (7%:5%), (6%:6%), and (5%:7%). The antimicrobial activity was tested against Escherichia coli and Staphylococcus aureus using the disc diffusion method on MHA media. The results showed that the extracts contain flavonoids, tannins, and organic acids that act as antimicrobial agents. The three formulations produced different inhibition zones, with formula 1 (7%:5%) effective against Escherichia coli (7.5 mm) and formula 3 (5%:7%) effective against Staphylococcus aureus (13 mm). The effervescent tablet had a dissolution time of <2 minutes.]]>

<![CDATA[West Sumatra faces a nutritional paradox in which low birth weight prevalence (6.4%) coexists with high stunting rates (24.9%), indicating chronic maternal micronutrient deficiencies during pregnancy. This study aimed to develop a local food innovation in the form of bilih fish (Mystacoleucus padangensis)-based finger food and analyze its macronutrient and micronutrient content to support maternal nutrition. A descriptive observational design with laboratory analysis based on Indonesian National Standards (SNI) was used. The results showed that the bilih fish finger food had an energy density of 188.19 kcal/100 g, a crunchy texture, and minimal fishy aroma, making it suitable for pregnant women, including those with emesis gravidarum. The protein content reached 16.52 g/100 g, fulfilling approximately 55–80% of the additional daily protein requirements during pregnancy. Zinc content was 1.32 mg/100 g (13.22 mg/kg), higher than several other local food sources such as dadiah and eggs. In conclusion, bilih fish-based finger food has strong potential as a functional local food to address maternal micronutrient deficiencies and serve as a preventive strategy to reduce stunting risk in West Sumatra starting from the intrauterine period.]]>

<![CDATA[Anemia remains a major public health issue in Indonesia, including Central Kalimantan, and is often linked to vitamin B12 deficiency. Vitamin B12 is typically found in animal-based foods; However, certain microorganisms involved in the fermentation of plant-based foods, such as cassava tapai, can synthesize this vitamin. This study aims to determine the vitamin B12 content and its variation in cassava tapai from Palangka Raya City based on fermentation duration. A comparative descriptive study with a quantitative approach was conducted using 16 samples obtained through purposive sampling from four local tapai producers at Pasar Besar A. Yani, Palangka Raya. Vitamin B12 levels were measured using UV-Vis spectrophotometry at 361 nm, and organoleptic properties (color, aroma, taste, texture) were analyzed descriptively. The results showed that all samples contained vitamin B12 ranging from 453,736,666.67 to 1,588,180,000.00 mcg/100g, with levels increasing along with fermentation time (days 1–4). Organoleptic tests revealed non-white color, alcoholic aroma, slightly sweet to unsweet taste, and soft texture. In conclusion, cassava tapai produced by MSMEs in Palangka Raya contains high levels of vitamin B12 and holds promise as a potential local food source to help prevent vitamin B12 deficiency anemia]]>

<![CDATA[Dengue Hemorrhagic Fever (DHF) is still one of the public health problems in Jambi City, especially in the working area of Kenali Besar Community Health Center which shows an increase in cases every year, with a larvae-free rate of 84%, still below the national target of ≥95%. Prevention efforts can be done through the implementation of 3M Plus behavior, but its implementation in the community is still not optimal. The purpose of this study was to determine the factors that influence the behavior of implementing 3M Plus in efforts to prevent Dengue Hemorrhagic Fever (DHF) in the working area of Kenali Besar Community Health Center, Jambi City in 2025. This study used a quantitative method with a Cross Sectional design. The population in this study were people living in the working area of Kenali Besar Community Health Center. The research sample consisted of 95 respondents selected using a multistage sampling technique. Data were collected using a questionnaire and analyzed using the Chi-Square test. The majority of respondents were in the 45-54 year age group (37.9%) and the majority of respondents were female (77.9%). The results of the study showed a significant relationship between knowledge (p-value = 0.01) and attitude (p-value = 0.00) with the behavior of implementing 3M Plus. Meanwhile, the availability of facilities and infrastructure (p-value = 0.60) and the role of health workers (p-value = 0.91) did not show a significant relationship. The better the community's knowledge and attitude, the greater the likelihood they will implement 3M Plus behavior in preventing dengue fever. It is hoped that health workers can improve education, assistance, and community empowerment to strengthen the implementation of 3M Plus in a sustainable manner.]]>

<![CDATA[One method to observe biofilms is by inoculating bacteria on glass slides and observed for the presence of large structures (microcolonies) and small structures (clusters, aggregates, or single cells) under a microscope. Analysis of these structures using image processing software may provide a method to quantify biofilm production and degradation in glass slides. In this study, we use ImageJ to quantify the number and area percentage of microbial structures observable on a slide. This study is an experimental in vitro study. Biofilm production was done by submerging slides in petri dishes filled with Brain Heart Infusion with 2% sucrose (w/v) and inoculating it with bacteria. The petri dishes were incubated undisturbed for 48 hours at 37°C (n=3). Afterwards, the slides were removed and submerged in distilled water (Group 1) or detergent (Group 2) for 5 minutes before staining with 0.1% crystal violet and rewashed. The slides were then observed under a light microscope at 1000x and images from five fields of view were collected. ImageJ was then used to count the number of microcolonies (>15.000 μm2), aggregate cells (200 – 14.999 μm2), and single cells or cell clusters (1 – 199 μm2), and their area percentage. Welch’s T-Test was performed using JASP version 0.18.3. Observation of slides shows microcolonies to be formed in Group 1, and no or little in Group 2. Based on ImageJ calculation, slides treated with distilled water had a biofilm consisting of an average 4.60 ± 2.41 microcolony number and an average percentage area of 39.97 ± 9.99%, 120.47 ± 32.31 (8.96 ± 3.19%) cell aggregates, and 415.06 ± 139.85 (1.39 ± 0.33%) single cells and cell clusters. Detergent application possibly showed biofilm breakdown, with a significant (p<0.001) reduction in microcolony percentage area to up to 99% (0.33 ± 0.68% remaining) and increased single cell number and percentage area to 1,754.93 ± 689.52 (5.27 ± 0.49%). ImageJ can be a valuable tool to quantify biofilm production in glass slides based on the number and percentage area of microcolonies, cell aggregates, and single cells or cell clusters.]]>
