Abstract

Background: Pulmonary tuberculosis (TB) and bacterial pneumonia are respiratory infections with high morbidity and mortality rates. Despite having similar clinical symptoms and radiological findings, these conditions require different treatment approaches. Procalcitonin is a potential biomarker to differentiate these conditions, as its levels tend to increase in bacterial infections but not in TB. This study aims to compare procalcitonin levels in patients with pulmonary TB and bacterial pneumonia. Methods: This research employed an observational analytic design with a cross-sectional approach conducted at Dr. Mohammad Hoesin General Hospital (RSMH), Palembang. The study subjects were patients with pulmonary TB and bacterial pneumonia who met the inclusion and exclusion criteria. Procalcitonin levels were measured using ELISA methods. Data were analyzed to determine differences in procalcitonin levels between the two groups. Results: The study found that procalcitonin levels in bacterial pneumonia patients were significantly higher than those in pulmonary TB patients (p<0.05). These findings indicate that procalcitonin levels can serve as a diagnostic parameter to distinguish between the two conditions. Conclusion: Procalcitonin levels can be a useful biomarker for differentiating pulmonary TB from bacterial pneumonia. This biomarker is expected to assist clinicians in making more accurate diagnoses and expediting clinical decision-making.

Abstract

Learning Enrichment to increase knowledge about ambiguous genitalia in students at STIKES Abdurrahman Palembang. Disorders of Sex Development (DSD) is a rare disease in which atypical gonads, chromosomes, and sex anatomy are found. Although it has a significant impact on both the physical and mental health of individuals with DSD, DSD cases are often undetected and underdiagnosed. Efforts to enrich material and learning to training on DSD for prospective midwife health workers are one of the real actions that can be taken to increase knowledge and awareness of DSD which is then expected to increase early identification efforts to improve the quality of life and patient outcomes. This community service activity was carried out for one semester through a series of activities in the form of guest lectures for enrichment of learning which were carried out in stages three times online for 55 students of STIKES Abdurrahman Palembang. Measurement of the level of knowledge of STIKES Abdurrahman students was carried out twice, namely before the series of activities began (pre-test) and after the activities were completed (post-test). From the results of the pre- and post-test, an increase in knowledge was obtained, which was originally only 36.4% with a sufficient level of knowledge at the time of the pre-test, to 69.1% with a sufficient level of knowledge at the time of the post-test. It is hoped that with the enrichment of learning, prospective midwives can know and understand DSD so that in the future they can improve early screening for ambiguous genitalia cases which can lead to improving the quality of life of sufferers.

Abstract

Introduction: Leprosy remains a significant problem in Indonesia as the number of cases has not been eliminated until now. One of the cytokines that plays a role in the disease is interleukin-10 (IL-10), which has a dominant anti-inflammatory effect and influences the immunopathogenesis of leprosy. Genetic factors, including the IL-10 gene promoter polymorphism, affect the amount of IL-10 produced, thereby increasing the risk of leprosy. Therefore, the objective of this study is to gather information on the role of IL-10 gene promoter polymorphism in the development of leprosy.Method: A systematic review method was used to identify, evaluate, and extensively discuss published works through national and international journals such as Google Scholar, Science Direct, Elsevier, EBSCO, Medline, PubMed, Proquest, and Wiley. The study was conducted by searching relevant keywords related to the research topic in these databases. Subsequently, article selection was performed based on predetermined inclusion and exclusion criteria. The selected articles were then evaluated for quality to ensure accuracy and reliability of the presented information. Finally, the results of this systematic review were used to obtain accurate and up-todate information regarding the role of IL-10 gene promoter polymorphism in leprosy.Results: This systematic review analyzed a total of 14 articles and revealed that results varied among study populations. However, there is consistent evidence to suggest that the IL-10 gene promoter polymorphism is associated with leprosy, which was found in the majority of the study populations.Conclusion: IL-10 gene promoter polymorphism tends to be associated with leprosy.

Abstract

Background: One of the side effects of the use of antiepileptic drugs (AEDs) is cognitive disorder. Several studies show a relationship between the type of AEDs and cognitive disturbance in people with epilepsy. Dose-dependent side effects of AEDs have also been reported in prior research. However, there are results from different studies on different populations. Objective: This research aims to evaluate the relationship between AEDs characteristics and the cognitive function of epilepsy patients. Methods: This cross-sectional study was conducted in the Neurology Department of Dr. Mohammad Hoesin General Hospital Palembang, from 1 November 2021 to 31 March 2022. Researchers used the MoCA-Ina questionnaire to collect medical record data and conduct interviews. Results: In this research, the number of research subjects obtained was 70 people with epilepsy. Characteristics of sociodemographic sufferer Epilepsy in this study was mostly (44.3%) aged 26 – 45 years with type sex most were women (71.4%), and the majority subjects (52.9%) had level high school education. Characteristics of antiepileptic drugs consumed by people living with epilepsy: most of them, i.e., amounting to 57.1%, have consumed antiepileptic drugs for > 12 months. Most of the research subjects (64.3%) had function-impaired cognitive range MoCA-Ina scores of 8 – 30. The function most cognitively disturbed, namely in the memory domain, cancels that am, counting to 82.9%. Education level is the only variable from characteristics of sociodemographic and clinical features connected significantly to cognitive function in general (p-value 0.013). The number, duration, and type of antiepileptic drugs do not determine a significant relationship with cognitive function in general. Conclusion: There is a significant relationship between valproic acid and the number of AEDs with the naming domain, as well as between valproic acid and the duration of AEDs with the abstraction domain.

Abstract

Pulmonary tuberculosis (PTB), primarily caused by Mycobacterium tuberculosis (M.tb), remains a major global health burden. Toll-like receptor 2 (TLR-2), a critical component of the innate immune system, plays a key role in the host-pathogen interaction by recognizing specific components of the mycobacterial cell wall and initiating downstream inflammatory pathways. However, the dual role of TLR-2 in both protective immunity and immune evasion by M.tb contributes to the complexity of TB pathogenesis. This study aims to investigate the role of Toll-Like Receptor-2 (TLR-2) in the pathogenesis of pulmonary tuberculosis, including its immunological mechanisms, relationships with disease severity, and the potential of TLR-2 as a diagnostic and therapeutic target. This literature review systematically analyzed molecular mechanisms involving TLR-2 signaling in pulmonary TB using peer-reviewed primary and secondary sources from experimental and clinical studies. Emphasis was placed on signal transduction (NF-κB and MAPK), cytokine profiles, antigen presentation, and the impact of TLR-2 gene polymorphisms on TB susceptibility. Activation of TLR-2 through ligands such as lipoproteins, lipoarabinomannan (LAM), and PE/PPE proteins initiates immune responses via MyD88-dependent pathways, leading to the release of proinflammatory cytokines (TNF-α, IL-6, IL-12). TLR-2 also enhances the function of macrophages and dendritic cells, promoting Th1-mediated immunity. However, chronic or excessive stimulation of TLR-2 can suppress antigen processing, promote IL-10 expression, inhibit phagolysosome fusion, and facilitate M. tb survival within host macrophages. Polymorphisms in the TLR-2 gene (e.g., rs3804099) have been associated with increased susceptibility and variable clinical outcomes in PTB. TLR-2 plays a paradoxical role in pulmonary tuberculosis by mediating both protective immunity and facilitating immune evasion by M.tb. Understanding the balance of TLR-2 signaling and genetic variation is crucial for developing immunomodulatory therapies and personalized interventions in TB management.

Abstract

ABSTRACT. Folate binding protein (FBP) is a protein in breast milk that plays a role in the regulation and bioavailability of folic acid. In contrast to cow's milk FBP, information about breast milk FBP is still limited. This research aims to determine the isolation and purification methods of breast milk FBP and the molecular weight of breast milk FBP. The sample in this study was 1000 mL of breast milk. Breast milk was prepared in several stages to yield whey. Isolation and purification of FBP from whey were carried out in stages, salting-out, ion exchange chromatography, and affinity chromatography. Whey salting-out with 95% saturation of ammonium sulfate could precipitate folate-binding proteins. This precipitate showed three peaks on DEAE chromatography. Peak II DEAE 95% was thought to be a negatively charged folate-binding protein. Peak II DEAE 95% also showed the presence of two peaks on affinity chromatography. It was believed that Peak II AF 95% was a pure folate-binding protein. Peak II AF 95% showed the presence of a single band on SDS-PAGE and western blot. This indicated that the folate-binding protein was 100% pure. FBP can be isolated from breast milk by the salting-out method using 95% ammonium sulfate, DEAE chromatography, and affinity chromatography. FBP from breast milk has a molecular weight of approximately 37 kDa. The final level of FBP isolated from breast milk is approximately 0.022 mg/mL. The successful isolation of FBP from breast milk provides an opportunity to use it to understand the clinical role of FBP in increasing folic acid levels in both breast milk and infant serum, as well as to develop methods for determining folic acid levels in these fluids. Keywords: Breast milk, folate binding protein, isolation, purification, molecular weight

Abstract

Penyembuhan luka merupakan proses biologis kompleks yang melibatkan fase inflamasi, proliferasi, dan remodeling jaringan. Pemanfaatan bahan alami dari laut, seperti siput gonggong (Laevistrombus sp.), menawarkan potensi besar sebagai agen penyembuh luka karena kandungan senyawa bioaktifnya yang memiliki aktivitas antimikroba, antiinflamasi, dan antioksidan. Penelitian ini bertujuan untuk meninjau potensi ekstrak siput gonggong dalam mempercepat penyembuhan luka melalui analisis terhadap kandungan bioaktif, mekanisme kerja, dan bukti histologis. Kajian dilakukan secara sistematis terhadap literatur dari PubMed, ScienceDirect, Google Scholar, dan Scopus dalam lima tahun terakhir hingga April 2025, dengan fokus pada aktivitas biologis moluska laut dan aplikasinya pada regenerasi jaringan kulit. Hasil tinjauan menunjukkan bahwa siput gonggong mengandung protein histon H2A, peptida antimikroba (AMPs), flavonoid, alkaloid, dan saponin yang berperan dalam menekan sitokin proinflamasi (TNF-α, IL-6), meningkatkan sitokin antiinflamasi (IL-10), serta menstimulasi proliferasi fibroblas, angiogenesis, dan sintesis kolagen melalui jalur NF-κB, PPAR-γ, dan TGF-β/Smad. Secara histologis, senyawa ini mempercepat reepitelisasi dan meningkatkan deposisi kolagen pada jaringan luka. Dengan demikian, ekstrak siput gonggong memiliki potensi besar sebagai bahan dasar alami untuk pengembangan produk dermatologis dan farmasi yang aman, efektif, serta berkelanjutan.
