Abstract

Fingerprints are utilized for personal identification, as well as to identify ethnicity, blood type and gender. They are permanent and remain unchanged throughout lifetime, unless an injury causes skin damage. This study aims to examine the variation in fingerprint patterns among students at OSO University, considering ethnic and gender differences. This study used a purposive sampling method and at least 50 fingerprint samples from students at the Faculty of Natural Sciences and Marine Science, OSO University. Generally, the loop fingerprint pattern is found in approximately 54.67% of the total sample of students. The loop fingerprint pattern is most commonly found in the Bugis, Malay and Javanese ethnic, while the Dayak ethnic predominantly has the whorl pattern. The arch fingerprint pattern is only found in the Dayak ethnic group. It can be assumed that the arch pattern may act as a distinguishing characteristic among ethnic groups in West Kalimantan. This study can contribute to forensic science, especially in identifying individuals based on fingerprint patterns associated with ethnicity and gender.  This research can provide as a foundation for further studies that explore the relationship between fingerprint patterns and other demographic factors, such as age or geographic location.

Abstract

Antibiotic resistance is an increasing global health challenge, especially in patients with advanced chronic kidney disease (CKD). This study aims to investigate cefixime resistance in patients with stage 4-5 CKD at Harapan Keluarga Hospital with a retrospective cohort design using medical record data. Chi-squared test analysis showed a significant association between cefixime resistance and advanced CKD (χ² = 34.714, p = 0.003). The results showed a higher prevalence of cefixime resistance in male patients (60%), antibiotic use of more than 14 days (65%), and hospitalization of more than five days (80%). The mechanism of resistance involves beta-lactamase production and changes in the gut microbiota due to dysbiosis. Factors such as irrational antibiotic use, length of hospital stay, and catheter use contributed to higher resistance. This study highlights the need for evidence-based antibiotic stewardship strategies to reduce resistance, especially in vulnerable populations such as patients with advanced CKD. Scientific implications include the development of more effective infection management strategies, close monitoring of antibiotic use, dose adjustment according to CKD severity, and education of health care workers to increase awareness of antibiotic resistance. This study contributes to efforts to prevent antibiotic resistance in the advanced CKD population.

Abstract

Geriatric individuals frequently suffer from insomnia, a sleep problem that significantly affects their general health and wellbeing. The purpose of this study is to examine the association between older adults' age, gender, and likelihood of suffering insomnia. Validated questionnaires were distributed at the Taliwang Health Center's Geriatric Clinic as part of a cross-sectional study. The findings indicate a significant relationship between aging and sleeplessness., with individuals aged ≥ 60 years being 5.342 times more likely to experience sleep disturbance than younger individuals (p = 0.0001). Gender also plays a significant role, with older men being 1.126 times more likely to suffer from insomnia than older women (p = 0.0001).

Abstract

Nasopharyngeal carcinoma (NPC) is one of the most common malignancies in the ENT department, with a high incidence in Southeast Asia. One of the major risk factors for NPC is formaldehyde exposure, which induces oxidative stress, chronic inflammation, and disruption of growth factors such as Epidermal Growth Factor (EGF). This study aims to analyze changes in EGF levels in Rattus norvegicus exposed to 40 ppm formaldehyde for one month to better understand the molecular mechanisms contributing to nasopharyngeal carcinogenesis. This experimental study measured EGF levels using the Enzyme-Linked Immunosorbent Assay (ELISA) method. Data were analyzed using the Kolmogorov-Smirnov normality test and a Paired T-Test to assess changes in EGF levels before and after treatment. The analysis showed a tendency for increased EGF levels after formaldehyde exposure; however, the difference was not statistically significant (p = 0.355). This suggests that one-month exposure to formaldehyde does not directly affect EGF expression in the tested tissue. This study found that 40 ppm formaldehyde exposure for one month did not significantly alter EGF levels. However, the observed trend in certain groups suggests that the effect of formaldehyde on EGF levels may be dose- and duration-dependent. Further studies with longer exposure durations and higher concentrations are needed to explore the link between formaldehyde exposure and nasopharyngeal carcinogenesis.

Abstract

A worldwide issue that has not been adequately addressed is stunting. One of the many causes of stunting is inadequate nutrition. There are two types of nutrients: macronutrients and micronutrients. Iron is one of the micronutrients that the body actually needs. Lack of iron consumption is one of the risk factors for stunting, according to a number of earlier research. The aim of this study was to ascertain the correlation between the occurrence of stunting in toddlers aged 24 to 59 months in the Nipah Health Center work area and iron (Fe) intake. This study employs a case control methodology and combines quantitative and analytical observational methods. Ultimately, we discovered that 30 individuals, or 78.95% of the 38 research participants, had iron intakes below 77%. The statistical test of iron consumption and stunting incidence showed that p = 0.042. This indicates that the incidence of stunting and iron intake are related.

Abstract

Curcuma sumatrana or Koenih Rimbo, is an endemic plant of West Sumatra that is threatened with extinction due to deforestation, climate change, and human activities. This study aims to understand the ecology of C. sumatrana to support effective conservation efforts. The study was conducted in seven potential locations in West Sumatra using exploration methods and analysis of environmental factors, such as altitude, temperature, humidity, soil pH, and canopy cover. The results showed that this species was only found in three locations, namely Lubuk Kilangan, Koto Malintang, and Koto Pulai, with the highest population in Koto Malintang. Environmental factors such as altitude, canopy cover, and air humidity were shown to support optimal growth of this species. Canonical Correspondence Analysis (CCA) identified a close relationship between environmental factors and morphological parameters, including plant height, number of branches, and leaf size. This study emphasizes the importance of natural habitat conservation and further research on the ecology of this species to prevent its extinction.

Abstract

Traditional land use is a method of land use that has been carried out for generations by the community. Land management activities carried out from generation to generation, with the same pattern from year to year, such as land use which is often called Tebas Bakar and Mamar. Both land uses with different management methods can indicate changes in soil conditions as a medium for plant growth in their physical properties. The purpose of this study was to determine soil permeability in traditional land cultivation activities in Niukbaun Village, West Amarasi, NTT. Field and laboratory research was carried out in August-October 2024. The research location was in Niukbaun Village, West Amarasi District, with the traditional Tebas Bakar and Mamar management systems. Research Methods Data collection includes primary data, secondary data, Permeability observations were carried out in the field using a permeameter. The results obtained: Soil permeability on mamar land is better than slash and burn land. Each type of traditional land use differs according to its management method. So that texture, organic material and land use processing have an influence on the size of the soil permeability.

Abstract

Depression is a common mental health disorder in the elderly, often coexisting with chronic conditions like hypertension. This study examines the relationship between depression and hypertension stage 2 among elderly individuals at Puskesmas Karang Taliwang, considering age and gender. A cross-sectional study of 30 elderly patients used a validated questionnaire to assess depressive symptoms. Results showed a significant association between age (≥60 years) and depression, while gender had no statistical correlation. Hypertension stage 2 was also significantly linked to depression, though with a small effect size. These findings highlight the need for integrated healthcare strategies addressing both mental and cardiovascular health in the elderly. Further research is needed to explore underlying mechanisms and potential interventions.

Abstract

The anti-fibrotic, anti-inflammatory, and antimicrobial qualities of moringa leaf extracts, which are high in saponins, flavonoids, steroids, and phenols, can aid in tissue regeneration and wound healing. The aim of this study was to prepare and formulate a transdermal patch of Moringa oleifera Lam. leaf extract with hydroxypropyl methylcellulose (HPMC) and polyvinyl pyrrolidone (PVP) as the polymers. The study was aimed at investigating the effect of various concentrations of the extract (20%, 40%, and 80%) on the physical properties of the patch, including organoleptic properties, weight uniformity, thickness, folding endurance, pH, and water absorption. Extract was made by maceration with 96% ethanol, and patches were cast by the solvent casting method. Results showed that all formulations met the required pH range (6.62–6.68), folding endurance (>300 folds), and thickness (<1 mm). However, weight uniformity and moisture absorption exceeded desired optimum values and ranged between 17% to 23%. The 20% concentration of extract exhibited the maximum physical stability. This study highlights the potential of Moringa oleifera leaf extract in transdermal patch preparations, although it needs to be optimized to improve weight consistency and water absorption.

Abstract

One of the bacterial pathogens that is often a serious concern in freshwater fish farming is Edwardsiella ictaluri, a causative agent of Enteric septicemia of catfish (ESC). Edwardsiella ictaluri which generally attacks catfish groups such as lele, patin, and sidat, but can also attack other species, such as tilapia. Therefore, alternative efforts are needed that are more environmentally friendly, safe for consumers, and do not trigger bacterial resistance. One of the plants that has the potential as a source of natural antibacterials is henna leaves (Lawsonia inermis L.). The purpose of this study was to determine the potential of henna leaf extract (Lawsonia inermis L.) as an antibacterial against Edwardsiella ictaluri and to determine the concentration of henna leaf extract (Lawsonia inermis L.) that is most effective in inhibiting the growth of Edwardsiella ictaluri bacteria. The method used in this study was disc diffusion. Analysis was conducted by testing the data for normality, homogeneity, kruskall wallis test and continued with the Dunn test using SPSS software version 26. The concentration of henna leaf extract of 3%, 6%, 12%, 24% and 48% is known to be able to inhibit the growth of Edwardsiella ictaluri bacteria with an average inhibition zone of 10.45 mm, 11.73 mm, 13.25 mm, 14.51 mm and 16.85 mm respectively. Henna leaf extract has the ability to inhibit the growth of Edwardsiella ictaluri bacteria with a strong category. A concentration of 48% is an effective concentration in inhibiting the growth of Edwardsiella ictaluri.
