Abstract

Organic fertilizers, such as earthworm fertilizer, and adjusting planting distances to meet plant demands can boost kale plant yields, particularly curly kale. The purpose of this study was to determine the effect of organic fertilizer dosage and planting distance on the growth and yield of kale (Brassica oleracea L. var. Acephala). The research method used a Split Plot Design approach involving two main treatment factors. The results found that the combination of 9 tons/ha (2.16 kg) of manure and a planting distance of 40 x 40 cm produced the best results for crown diameter. The combination of 6 tons/ha (1.44 kg) of manure and a planting distance of 20 x 40 cm gave the best results for fresh root weight per plant at harvest. All criteria were not significantly affected by the use of manure. The treatment of a planting distance of 30 x 40 cm gave the best results for plant height, which was 31.96 cm. Regarding the findings of this study, further researchers can conduct soil analysis before administering the manure coat and re-analyze it after 1 month of administration to determine the quality of the fertilizer content and pay attention to the balance of planting distance for plants, so as to prevent the emergence of diseases caused by high humidity and nutrient competition between plants. Fertilization can also be given to increase yields. The conclusion is that the administration of organic fertilizer doses and planting distances affect the growth and yield of Water Spinach (Brassica oleracea L. var. Acephala).

Abstract

Hemorrhagic stroke is an acute condition characterized by the rupture of blood vessels in the brain and has a high mortality rate. The bleeding leads to the formation of hematoma and perihematomal edema, which significantly worsen the patient's prognosis. Early diagnosis and management are crucial to improving clinical outcomes. In recent years, blood-based molecular biomarkers have become a major focus of research due to their potential to support diagnosis, evaluate etiology, predict hematoma growth, and assess inflammatory responses. Biomarkers such as GFAP and S100B have proven effective in distinguishing hemorrhagic stroke from ischemic stroke in the hyperacute phase. Meanwhile, β-amyloid and MMP play roles in identifying the etiology of bleeding, especially related to cerebral amyloid angiopathy. Additionally, levels of calcium, magnesium, LDL-C, and ApoE ε2 are known to be associated with the risk of hematoma expansion. Inflammatory biomarkers such as CRP, NLR, gelsolin, and CD163 reflect neuroinflammatory processes and blood-brain barrier damage that worsen secondary injury. The clinical use of these biomarkers opens opportunities for faster, more accurate, and personalized diagnostic and therapeutic approaches in hemorrhagic stroke.

Abstract

The biological reaction to tissue damage known as inflammation is typified by the production of mediators including cytokines and prostaglandins. Long-term usage of non-steroidal anti-inflammatory medicines (NSAIDs) can have negative effects, despite their widespread use. This study explores the potential of Terminalia mantaly H. perrier (ketapang kencana), a plant known to contain various bioactive compounds, as a natural anti-inflammatory agent. The aim of this study was to analyze the phytochemical content and evaluate the anti-inflammatory activity of ethanol extracts of T. mantaly leaves using the Bovine Serum Albumin (BSA) protein denaturation method. 70% and 96% ethanol were used in the maceration process for extraction. The 70% ethanol extract included flavonoids, tannins, saponins, triterpenoids, terpenoids, and alkaloids, according to phytochemical screening. With an IC₅₀ value of 27,86 ppm Terminalia mantaly etanol extract 70%, the anti-inflammatory test revealed that the 70% ethanol extract at 400 ppm reduced protein denaturation by 92,29%, which was comparable to the inhibition by sodium diclofenac (84,04% at 50 ppm).  These results suggest that polar compounds in the 70% ethanol extract significantly contribute to its anti-inflammatory effect. Therefore, T. mantaly leaf extract demonstrates promising potential as a natural phytopharmaceutical candidate for inflammation therapy.

Abstract

Neisseria gonorrhoeae is the bacteria that causes gonorrhea, a sexually transmitted infection (STI). The reproductive system, rectum, and pharynx are particularly susceptible to this infection. Both men and women can have gonorrhea, but women frequently have moderate or even nonexistent symptoms, which makes the infection go undiagnosed and untreated. This raises the possibility of severe side effects like infertility, pelvic inflammatory disease (PID), and transmission to fetuses or infants. According to a World Health Organization (WHO) assessment, gonorrhea is still a common global health issue, particularly in underdeveloped nations. Factors such as low awareness of STIs, limited access to health services, and increasing antibiotic resistance contribute to the challenges of controlling this disease. Throughout the twentieth century, gonorrhea (GO) was the most prevalent sexually transmitted infection (STI) globally due to delayed diagnosis. Gonorrhea was more common in women than in men in 2009, and the most common sources of reporting for women were emergency rooms (5.8%), STI clinics (16.7%), family planning clinics (9.1%), and other health department clinics (8.1%). Other sources of reporting were private physicians and health maintenance organizations (30.9%). According to WHO figures from 2012, there were 78 million GO infection cases. The frequency was 0.8% for women and 0.6% for males among those aged 15 to 49. According to WHO estimates from 2016, the combined global prevalence of urogenital gonorrhea (the percentage of the world's population that has gonorrhea in a given year) was 0.9% for women and 0.7% for men, or 30.6 million cases globally.

Abstract

Chronic Obstructive Pulmonary Disease (COPD) is a progressive respiratory disorder and a leading cause of morbidity and mortality worldwide. Despite advances in research, COPD continues to impose a significant global health and economic burden. This article is a narrative review of current literature focusing on the definition, epidemiology, etiology, pathophysiology, clinical manifestations, management, and complications of COPD. Relevant studies, international guidelines, and recent updates were analyzed to provide a comprehensive understanding of the disease. COPD prevalence is increasing globally, especially in developing countries, with smoking, air pollution, occupational exposures, and genetic susceptibility identified as major risk factors. Pathophysiological mechanisms include chronic inflammation, oxidative stress, and protease–antiprotease imbalance, leading to irreversible structural changes in the lungs. Clinically, patients present with chronic cough, sputum production, and progressive dyspnea. Management involves risk factor control, pharmacological treatment, pulmonary rehabilitation, and multidisciplinary care. Complications such as recurrent exacerbations, pulmonary hypertension, and chronic respiratory failure further worsen prognosis. In conclusion, a comprehensive understanding of COPD from multiple perspectives is crucial for optimizing prevention, diagnosis, and treatment. This review emphasizes the need for early detection, integrated therapeutic approaches, and ongoing research to reduce the global burden of COPD.

Abstract

One prevalent mood illness in the prenatal period that has a significant impact on the quality of early childhood development is maternal depression. Due to socioeconomic position, a lack of social support, and restricted access to healthcare facilities, this condition in Indonesia develops into a complicated public health concern. This study aims to comprehensively review the association between maternal depression and the cognitive, emotional, social, and physical development of children within the local Indonesian context. This article was composed through a systematic review of nine relevant primary scientific articles. A literature search was conducted on the PubMed, NCBI, Elsevier, and Google Scholar databases using relevant keywords. The review indicates that maternal depression negatively impacts various domains of child development. Cognitively, children of mothers with high-stress levels tend to experience difficulties with focus and concentration. In the socio-emotional domain, these children show difficulties in emotion regulation and tend to withdraw from social interaction. Physically, maternal depression was found to have a positive correlation with an increased risk of stunting in children. This impact is reinforced by contextual factors in Indonesia, such as the scarcity of maternal mental health services, minimal screening, and social stigma that prevents mothers from seeking help. The conclusion is that maternal depression is a serious health issue in Indonesia with multidimensional impacts on child development. Integrated efforts are needed, including routine screening, capacity building for health workers, and culturally sensitive interventions to reduce the burden of maternal depression and prevent its long-term effects on children.

Abstract

Sunlight contains ultraviolet (UV) radiation, which is part of the electromagnetic spectrum. Low awareness of the importance of skin protection, as well as the perception that sunscreen use is incompatible with masculine image, is due to a lack of education. This paper aims to discuss the importance of sunscreen use as a preventive measure in maintaining skin health, especially in areas with high UV exposure such as NTB. The results of a literature study found that ultraviolet light is part of the electromagnetic spectrum originating from the sun. UVA, UVB, and UVC rays are the three types of these rays that may be distinguished by their wavelength. One of the major risk factors for developing skin cancer is exposure to UVA and UVB radiation. Sunscreen is one way to chemically protect the skin from the sun. Active ingredients in sunscreen have the ability to absorb, disperse, and reflect sunlight to provide the best possible protection for the skin. The chemical structure known as aromatic molecules conjugated with carbonyl groups is the mechanism of action of chemical sunscreens. The degree of hyperpigmentation is greatly impacted by proper sunscreen use. In conclusion, the public should be taught about the importance of wearing sunscreen in order to avoid the acute and long-term consequences of excessive UV exposure.

Abstract

The first 6–24 months of life is a critical “golden period” of rapid growth during which adequate and diverse nutrition is crucial. Low dietary diversity during the introduction of complementary foods (MP-ASI) can increase the risk of chronic malnutrition and stunting, and the persistently high prevalence of stunting in Central Lombok motivates investigation into the role of MP-ASI variation on linear growth. This cross-sectional, observational analytical study aimed to determine whether MP-ASI variation is associated with stunting in children aged 6–24 months in the Puyung Community Health Center area. Data were collected from October–December 2024 on ninety mother-child pairs or caregivers selected using stratified random sampling. Of the 90 children, 26 (28.9%) had inadequate MP-ASI variation (<5 food groups/day) and 49 (54.5%) were classified as stunted. Bivariate analysis using chi-square test showed no statistically significant association between variations in complementary feeding and stunted growth (p = 0.693). Variations in complementary feeding were not significantly associated with stunted growth in children aged 6–24 months in the Puyung Community Health Center area. Nutrition programs should continue to promote dietary diversity in addition to interventions that address sanitation, maternal nutrition, and other contextual determinants of stunted growth.

Abstract

A public health concern, stunting impacts children's physical and cognitive development, especially in toddlers. In order to prevent stunting, socioeconomic factors including parental education and parenting style are crucial. The purpose of this study was to examine the relationship between stunting in children aged 6 to 24 months in the Puyung Public Health Center's service area in Central Lombok and parental education and parenting style. This observational study used a cross-sectional design involving eight integrated health posts (posyandu). Stratified random sampling was used to identify 90 parents with children between the ages of 6 and 24 months as study participants. Information was gathered via questionnaires and the Maternal and Child Health (MCH) book. The chi-square test was used for bivariate analysis. 54.4% of the population was stunted. The majority of dads (48.9%) and women (46.7%) had completed senior high school. The majority of respondents (73.3%) thought that parenting was good, with democratic parenting being the most popular (46.7%). There was no statistically significant correlation between the incidence of stunting (p>0.05) and maternal education (p=0.080), father education (p=0.387), parenting category (p=0.655), or parenting type (p=0.402). In conclusion, there was no discernible link between stunting in children aged 6 to 24 months in the Puyung Public Health Center's service area in Central Lombok and parental education or parenting style. More studies with bigger sample sizes and examination of other affecting variables like socioeconomic status and diet are among the recommendations.
