Abstract

Long beans (Vigna sinensis L.)  require sufficient nutrients for their growth. To increase nutrients, fertilization needs to be carried out using either chemical fertilizers or organic fertilizers. Bokashi is an organic fertilizer that can be applied to agricultural land. Research on the analysis of vegetative growth of Vigna sinensis L due to bokashi and NPK fertilizer treatments has been conducted with the aim of analyzing the effect of bokashi, NPK fertilizer, and the interaction of the two treatments on the vegetative growth of Vigna sinensis L. In this study, a completely randomized design with 2 factors was used. Long bean  growth parameter including number of leaves, leaf length, leaf width and stem length were analyzed using analysis of variance. The results of the study showed that there was an increase in the number of leaves, stem length and leaf length but there was no increase in leaf width after bokashi treatment. NPK fertilizer treatment can increase all growth parameters, The interaction between bokashi and NPK fertilizer did not have a significant effect on the growth parameters of  Vigna sinensis L. Farmers are recommended to use 16 tons of bokashi for 1 hectare of agricultural land combined with 1.5 g of NPK fertilizer for 1 long bean.

Abstract

Aortic stenosis is among the most common valvular heart diseases, particularly in the elderly, and remains a major cause of morbidity and mortality. It is characterized by narrowing of the aortic valve, leading to increased afterload, compensatory left ventricular hypertrophy, and eventual heart failure or sudden death. To summarize updated evidence on the pathophysiology, clinical manifestations, and diagnostic signs of aortic stenosis. A literature review was conducted through systematic searches of PubMed, ScienceDirect, and Google Scholar, prioritizing publications from the last ten years. Articles on anatomy, physiology, pathophysiology, clinical features, diagnostic findings, and disease progression were critically analyzed. Aortic stenosis develops through degenerative calcification, rheumatic autoimmune inflammation, or congenital malformation. Disease progression leads to elevated transvalvular gradient, reduced stroke volume, and left ventricular hypertrophy. Typical symptoms include angina, syncope, and heart failure. Key diagnostic signs are a crescendo–decrescendo systolic ejection murmur radiating to the carotid arteries and the Gallavardin phenomenon. Aortic stenosis is a progressive valvular disease with complex pathophysiological mechanisms. Comprehensive understanding of its biological processes, clinical manifestations, and diagnostic signs is essential to support early detection and timely management. Such efforts may reduce morbidity and mortality while paving the way for innovative therapeutic strategies in the future.

Abstract

Diabetes Mellitus is a disease with the fifth highest mortality rate in the world because it can cause serious complications such as neuropathy, nephropathy, and retinopathy. This study aims to determine the pattern of use of antidiabetic type 2 drugs in hospitalized patients at the NTB Provincial Hospital in 2023. This study was retrospective using the Probability Sampling method, namely the Simple Random Sampling type, so that a sample of 90 medical records of patients with type 2 diabetes mellitus was obtained. The data were analyzed using chi-square test using Microsoft Excel and SPSS version 25. The results of the study showed that the use of insulin antidiabetic drugs with a fast-acting insulin class was the most prescribed antidiabetic drug with a total of 603 (42.33%), while oral antidiabetic drugs with a biguanide class, namely metformin, were the most widely used oral antidiabetic drugs with a total of 246 (52.45%). Gender, age, and BMI did not significantly correlate with patient blood sugar management, according to the Chi-Square test analysis (p value > 0.05). However, the blood sugar control treatment time revealed a p value < 0.05, indicating a substantial correlation between the two variables. The study concludes that, according to the pattern of type 2 antidiabetic medication usage among hospitalized patients at the NTB Provincial Hospital in 2023, the most commonly used medications in the NTB Provincial General Hospital during that year were 603 (42.33%) insulin class antidiabetic medications, specifically rapid-acting insulin.

Abstract

Cranial nerves are an integral part of the peripheral nervous system, playing a crucial role in transmitting afferent and efferent nerve impulses, particularly in the head and neck area. Unlike spinal nerves, cranial nerves have distinct functional nuclei in the brainstem, grouped into sensory (posterior and lateral) and motor (anterior) nuclei. The optic nerve is a purely afferent (sensory) nerve, responsible for transmitting visual information from rod and cone receptors in the retina to the lateral geniculate nucleus (LGN) and superior colliculus (SC) in the thalamus. The optic nerve's innervation pathway begins with retinal ganglion cells, which form nerve fibers, pass through the optic canal, and then cross at the optic chiasm. Disruption of this pathway can lead to various clinical manifestations, such as vision loss or visual field impairment, which will be discussed further. Therefore, a thorough understanding of the anatomy and function of the optic nerve is crucial for the diagnosis and treatment of neuro-ophthalmological conditions.

Abstract

Melon is a horticultural crop that has high-income potential, but in 2023 the production of melon in Indonesia declines drastically. Hence, research and collaboration to increase the production of melon in Indonesia is essential. This study was aimed to analyze the effect of NPK fertilizer and chicken manure fermented on growth and yield of melon (Alisha variety). This study conducts by analysing the effect of combination of NPK fertilizer and chicken manure fermented on growth and yield Cucumis melo L. alisha variety using Randomized Group Design (RGD) consisting of 7 treatment combinations. The parameters of plant height, number of leaves, stem diameter, fruit weight, and the level of sweetness (oBrix) of melon fruit were analyzed using Duncan’s Multiple Range Test (DMRT) at P<0.05. The results show that 300 kg/ha NPK fertilizer + 0 t/ha chicken manure fermented gave the best growth and yield with a melon weight of 61.50 t/ha, however, it was not significantly different from the combination treatment of 100 kg/ha NPK fertilizer + 15 t/ha chicken manure (F) on fruit weight per plot. The results of this study will be the basis of considerations in using a combination of NPK and chicken manure fermented to increase the growth and yield of Cucumis melo L. (Alisha variety).

Abstract

The use of bulk cooking oil added with shallot powder has no known effect on the body so it is necessary to conduct a study to determine the effect of the addition of shallot powder as a natural antioxidant added to bulk cooking oil in mice on one of the qualitative benchmark parameters in the form of cytological examination of blood. This study aims to find out about the effect of bulk cooking oil added with antioxidants, namely shallot powder on the cytological picture of the blood of mice (Mus musculus) whose analysis results are compared with bulk cooking oil added with synthetic antioxidant BHT and bulk cooking oil without the addition of antioxidants. Toxicity test was determined by blood cytology examination by looking at several parameters, namely erythrocyte morphology, erythrocyte count, leukocyte count and diff count. The results of 1-way Anova test statistical data show that there is no effect of giving onion powder in bulk cooking oil to mice (Mus musculus) on the number of erythrocytes and leukocytes. While in the diff count, the results of the Paired Sample t-test statistical data show that there is an effect of adding onion powder to bulk cooking oil in mice (Mus musculus), namely an increase in lymphocytes and neutrophil segments.

Abstract

Cholangiocarcinoma (CCA) is a malignant tumor of the biliary epithelium and represents the second most common primary liver cancer after hepatocellular carcinoma. Its incidence and mortality rates are particularly high in Asia. This review aims to provide an updated overview of risk factors, pathogenesis, diagnostic strategies, and current management of cholangiocarcinoma based on recent scientific evidence from the past decade. A narrative literature review was conducted using publications retrieved from PubMed, Scopus, and Google Scholar, limited to the last 10 years. Eligible studies included original research, systematic reviews, clinical trials, and international clinical practice guidelines addressing epidemiology, biomarkers, imaging modalities, molecular testing, as well as surgical and non-surgical treatment options. CCA is classified into intrahepatic (iCCA) and extrahepatic (eCCA: perihilar and distal). Risk factors include parasitic infections, congenital biliary anomalies, cirrhosis, viral hepatitis, and toxin exposure. Management depends on resectability: surgical resection with adjuvant capecitabine provides curative benefit, while advanced disease requires systemic chemotherapy (gemcitabine–cisplatin), second-line FOLFOX, and palliative interventions such as biliary stenting and drainage. Early detection in high-risk populations is essential to improve diagnostic accuracy and treatment outcomes. A multimodal strategy combining biomarkers, imaging, and molecular analysis enhances early recognition and guides therapy. Routine screening programs, development of novel biomarkers, and further studies on targeted therapies and immunotherapy are recommended to broaden future treatment options.

Abstract

Abnormalities in immune system development and function result in increased susceptibility to infection and reactivation of latent infections. Other immunodeficiencies can result in mild infections and may first be detected in adulthood. This literature review aims to discuss primary immunodeficiencies, including their definition, causes, treatment, and examples of the diseases they cause. This literature review was compiled through a literature search method by reviewing various scientific journals obtained from databases such as PubMed, Google Scholar, and ScienceDirect. The results Primary immunodeficiency disease (PID) results from immune system defects caused by mutations in the genetic code that codes for components of the body's immune system. PID is broadly classified as either a disorder of adaptive immunity (T-cell, B-cell, or combined immune deficiencies) or innate immunity (phagocyte and complement deficiencies). Patients with PID may experience a variety of lung problems, including recurrent lower respiratory tract infections, lung parenchymal abnormalities, asthma, ventilation abnormalities, and bronchiectasis (BE). In conclusion, primary immunodeficiency disease (PID) refers to a large, heterogeneous group of disorders characterized by abnormalities in the development and/or function of the immune system. These conditions result from immune system defects caused by mutations in the genetic code that codes for components of the body's immune system.

Abstract

Anemia is a global health problem affecting approximately one-quarter of the world's population and remains a major concern in Indonesia, particularly among adolescents and young adults. University students, as part of the young adult group, are at risk of developing anemia due to several factors, especially unhealthy dietary patterns, unbalanced diets, and insufficient intake of macro- and micronutrients essential for hemoglobin synthesis. This study aims to examine the relationship between dietary patterns and the incidence of anemia among university students, particularly medical students. This research employed a literature review method using purposive sampling from PubMed, Google Scholar, and ScienceDirect databases, with the keywords “dietary patterns” and “anemia.” A total of 24 relevant articles in both Indonesian and English were analyzed descriptively. The findings indicate a significant relationship between dietary patterns and anemia. Low consumption of iron, vitamin B12, and folate, along with habits such as skipping breakfast, are associated with a higher risk of decreased hemoglobin levels. Several studies demonstrated a significant correlation between dietary quality and anemia, although some reported inconsistent results.

Abstract

Refractive disorders, including myopia, hyperopia, astigmatism, and presbyopia, often appear from childhood, especially adolescence, through to old age. These conditions significantly impact the quality of life, academic achievement, and psychosocial well-being of sufferers. This literature review outlines article analysis to determine how to prevent, detect, and treat refractive disorders in adolescents. The review method used systematic literature. The findings of the literature study indicate that refractive disorders are a major cause of visual impairment, especially in adolescents who are still growing. Refractive disorders can impact students' quality of life and academic achievement. Diagnosis is made by examining visual acuity using a Snellen chart or LogMAR, followed by a corrective lens test. Treatment of refractive disorders can include the use of glasses, contact lenses, and refractive surgery procedures such as LASIK. The increasing global prevalence of refractive disorders emphasizes the importance of prevention, early detection, and appropriate management to reduce blindness and improve quality of life. In conclusion, prevention, early detection, and treatment of refractive disorders in adolescents can be used to avoid or reduce these diseases.
