Abstract

Von Willebrand disease (vWD) is the most common hereditary bleeding disorder caused by a deficiency or dysfunction of von Willebrand factor (vWF), a key protein involved in both primary and secondary hemostasis. This study aims to review the current understanding of diagnosis, classification, and management strategies for vWD based on disease type and severity. A literature review approach was employed to analyze recent findings on the pathophysiology, diagnostic criteria, and therapeutic advances related to vWD. Accurate diagnosis remains crucial, as treatment must be tailored to the specific subtype and clinical severity. Current management focuses on increasing circulating levels of vWF and factor VIII through local hemostatic measures, antifibrinolytic agents such as tranexamic acid, desmopressin (DDAVP) for responsive patients, and vWF/factor VIII concentrates for severe cases or DDAVP contraindications. A multidisciplinary perioperative management plan is essential to minimize bleeding risks during surgical or invasive procedures. Despite advances in therapy, challenges persist in early detection and individualized treatment optimization. Comprehensive evaluation, improved clinical awareness, and collaborative care among healthcare providers are vital to enhancing patient outcomes and quality of life.

Abstract

Bacterial infections caused by pathogenic microorganisms remain a serious global health issue, exacerbated by the increasing incidence of antimicrobial resistance. Although synthetic antibacterial agents are effective, concerns have arisen regarding their long-term toxicity, bioaccumulation, and environmental impact. Consequently, the exploration of natural, safe, and eco-friendly antibacterial sources has gained significant attention. Tropical fruit peels, which are abundant agro-industrial by-products, contain diverse bioactive compounds such as flavonoids, tannins, saponins, and alkaloids that exhibit strong antibacterial potential. This literature review systematically evaluates the potential of tropical fruit peel extracts as active ingredients in antibacterial product formulations. Using a systematic review method, articles were collected from databases such as PubMed and Google Scholar, focusing on studies published between 2015–2025 that assessed the antibacterial activity of ethanol extracts from tropical fruit peels against bacteria including Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Streptococcus mutans, and Klebsiella pneumoniae. The findings indicate that peels of pineapple (Ananas comosus), banana (Musa spp.), mango (Mangifera indica), papaya (Carica papaya), pomelo (Citrus maxima), mangosteen (Garcinia mangostana), and durian (Durio zibethinus) show significant antibacterial activity. These extracts have been successfully formulated into antiseptic soaps, hand sanitizers, nanoemulgels, and herbal mouthwashes, offering effective and sustainable alternatives to synthetic antibacterial agents.

Abstract

Guillain-Barré syndrome (GBS) is a disorder in which the body's immune system attacks the peripheral nervous system due to molecular mimicry, characterized by progressive muscle weakness from distal to proximal. This systematic review examines the relationship between vaccination and the risk of GBS. Epidemiological data indicate that the incidence of GBS after vaccination is very low. Although there is a link between vaccination and GBS in some cases, the risk remains smaller than the risk of GBS due to natural infection with the pathogen. This study emphasizes that the benefits of vaccination in preventing infection outweigh the risk of vaccination causing GBS. Guillain-Barré syndrome (GBS) is a disorder in which the body's immune system attacks the peripheral nervous system due to molecular mimicry, causing muscle weakness that progresses rapidly to paralysis. From this literature review, it can be concluded that the risk of GBS after vaccination is very low and is limited to certain vaccines. Furthermore, GBS cases occur more frequently after viral or bacterial infections than after vaccination, indicating that the benefits of vaccination in preventing infectious diseases far outweigh the risk of causing GBS.

Abstract

Coastal waters play a vital role in supporting ecological balance and socio-economic activities in island regions such as Lombok, Indonesia. Rapid tourism growth, coastal settlements, and marine transportation have increased environmental pressures on these ecosystems. This study aims to provide a comprehensive overview of the ecological condition of Lombok’s coastal waters through a Systematic Literature Review (SLR) of ten scientific articles published between 2014 and 2025. The review follows the PRISMA protocol, focusing on themes of water quality, mangrove and coral reef ecosystems, pollution, and coastal management. The analysis reveals that most coastal areas in Lombok still meet the national seawater quality standards (PP No. 22/2021), with parameters such as temperature, salinity, and dissolved oxygen remaining within optimal ranges. However, nutrient enrichment and trace metal accumulation have been detected in high-activity zones like Mandalika and Teluk Kodek. Mangrove and coral ecosystems in Gili Petagan and Gili Matra remain relatively healthy, supporting conservation and eco-tourism potential. The findings emphasize the need for integrated, science-based management involving community participation to maintain ecological stability while promoting sustainable blue economy development toward Indonesia’s 2045 Vision.

Abstract

Scabies is a contagious disease caused by the Sarcoptes scabiei var.hominis mite which commonly occurs in neonates and children due to close physical contact and low immune systems. Scabies disease can be found throughout the world without influence by age, race, and socio-economic conditions of the community. Scabies is transmitted through direct skin contact, with a higher risk in environments with poor sanitation. Clinical symptoms that may appear include itching that worsens at night, the formation of papules and burrows. In neonates or infants, symptoms such as crying and restlessness may occur, while in older children, symptoms such as insomnia, fatigue, and lethargy due to itching at night may occur. This paper aims to provide a comprehensive understanding of the epidemiology, diagnosis, and management of scabies. The writing method used in this literature review is based on references from various sources in Indonesian and English literature. The results of this literature review scabies is a contagious disease caused by the Sarcoptes scabies var hominis which can occur worldwide with a life cycle that occurs on human skin. The diagnosis of scabies can be confirmed by the discovery of two of the four presumptive diagnoses. Management of scabies focuses on preventing the spread, reducing risk factors, and supporting pharmacological treatment. Scabies is a parasitic infection that affects a person's quality of life.

Abstract

This Wastewater treatment plants are essential for reducing pollution before wastewater is discharged, but conventional systems often fail to achieve effective pollutant removal . This study aimed to measure the effectiveness of mangrove powder in treating industrial wastewater before it is discharged into the environment to improve wastewater quality. Samples were taken at two points: after conventional wastewater treatment and after treatment with mangrove biofiltration. The biofiltration system was designed to address the limitations of conventional treatment, particularly in reducing BOD₅, COD, phosphate, MBAS, and increasing dissolved oxygen (DO). Sampling was carried out using a  one liter sterile sample bottle. Sampling was carried out using a 1-liter sterile sample bottle. Sampling was carried out at one point with four repetitions. Parameters analyzed included TSS, pH, DO, BOD₅, COD, nitrate, nitrite, ammonia, phosphate, sulfate, and MBAS detergent. Mangrove biofiltration achieved reductions in TSS (55.26%), COD (99.35%), nitrate (100%), BOD₅ (99.15%), phosphate (96.67%), sulfate (99.55%), nitrite (100%), ammonia (90.00%), and MBAS (100%), while DO increased by 47.37% and pH remained stable. These improvements indicate the mangrove biofilter’s capacity to adsorb and biologically degrade organic matter and pollutants, enhancing wastewater quality to meet reuse standards. The results of the study show the potential of mangrove-based biofiltration as a solution for waste treatment units using mangrove biofiltration to reduce the concentration of DO, BOD, COD, phospat, Detergen MBAS, and Ammonis in industrial waste before being discharged into the environment.

Abstract

Seagrass is a higher plant from the Anthophyta division that lives below the surface of the air in shallow marine environments. Seagrass ecosystems play a crucial role in carbon sequestration through photosynthesis, which absorbs carbon from the environment. This study aims to estimate carbon stocks in seagrass meadows along the coastal area of Pemenang District, North Lombok. The study was conducted from April to June 2024 using a geographic information system (GIS) approach combined with field observations. The sampling method used a GIS approach to determine the distribution and level of seagrass cover. Seagrass cover levels were classified into three classes: high, medium, and low. Seagrass samples were taken at each cover level and then analyzed in the laboratory to measure biomass and carbon content to estimate carbon stocks. The results showed that the total area of ​​ seagrass beds in Pemenang District reached 685.26 hectares, consisting of eight species, namely Enhalus acoroides, Thalassia hemprichii, Halodule pinifolia, Halodule uninervis, Halophila ovalis, Cymodocea rotundata, Cymodocea serrulata, and Syringodium isoetifolium. Halodule uninervis contributed the highest carbon stock (54.12 gC/m²), followed by Halodule pinifolia (53.22 gC/m²) and Thalassia hemprichii (51.16 gC/m²). The total seagrass carbon stock across the study area was 2.53 tons/Ha, with above-ground biomass at 0.826 tons/Ha and below-ground biomass at 1.7 tons/Ha, amounting to an estimated total of 1,735 tons of carbon. Spatial analysis indicated an even distribution of seagrass meadows along the Pemenang coastline.

Abstract

This research was conducted in the Utilization Block of the Kerandangan Nature Tourism Park, West Lombok, to analyze the abundance and feeding preferences of butterflies of the family Nymphalidae. The background of the study is based on the important role of butterflies as pollinators as well as bioindicators of ecosystem health, and the limited recent data regarding their diversity in this area. The methods used include species identification using the time search technique and vegetation analysis using double-square plots to determine the types of host plants. The data were analyzed descriptively and quantitatively through diversity, evenness, species richness, similarity, dominance indices, as well as feeding preferences and importance value indices. The study recorded 112 individuals from 28 butterfly species. The habitat with the highest abundance was Open Spaces (35 individuals, 17 species), while the lowest was in Secondary Forest (12 individuals, 8 species). The highest Shannon-Wiener diversity index was recorded in Open Areas (H’=2.73; moderate category). Butterfly feeding preferences were dominated by flowers from the families Asteraceae, Acanthaceae, Fabaceae, Moraceae, and Apocynaceae, with Ageratum conyzoides being the most preferred nectar source. Around 90% of butterflies used flowers as an energy source, while 10% consumed decaying fruit. In conclusion, the Kerandangan Nature Reserve has a fairly high diversity of Nymphalidae butterflies, with the availability of flowering vegetation being a key factor in species abundance and distribution.

Abstract

Hyperthyroidism, a condition of excessive thyroid hormone production, presents significant diagnostic and management challenges worldwide. Its clinical spectrum is broad, influenced by etiology, patient demographics, and regional factors. This study was conducted to provide a detailed description of the clinical characteristics, demographic profile, and management patterns of hyperthyroid patients at Dr. (H.C) Ir. Soekarno Regional General Hospital, a tertiary care center in Bangka Belitung Province. This research utilized a descriptive observational method with a cross-sectional design. Data were retrospectively collected from the medical records of 83 patients diagnosed with hyperthyroidism between January and December 2024. The collected variables included age, gender, clinical manifestations, laboratory findings, and prescribed therapeutic regimens. The analysis revealed a significant female predominance (86.7%) among patients, with the majority falling into the >35 years age group (56.6%), confirming established epidemiological trends. The most prevalent clinical findings were palpitations (90.4%), goiter (85.5%), and unexplained weight loss (78.3%). Graves' disease was identified as the primary etiology in 72.3% of cases. The mainstay of treatment was pharmacotherapy, with Methimazole being the most frequently prescribed antithyroid drug (81.9%), often supplemented with beta-blockers (74.7%) for symptomatic control. This study concludes that the clinical profile of hyperthyroidism at this tertiary hospital aligns with classical presentations, predominantly affecting adult women. The findings underscore the importance of recognizing key symptoms for early diagnosis and affirm that current management practices are consistent with established clinical guidelines.

Abstract

The Javan gibbon (Hylobates moloch) is a primate endemic to Java Island that plays a crucial ecological role as a seed disperser and indicator of rainforest health. This study aims to analyze the daily behavioral patterns of the Javan gibbon (Hylobates moloch) at the ex-situ conservation site Lombok Wildlife Park to assess its expression of natural behaviors and welfare conditions. The research was conducted from September 2024 to January 2025 using the ad libitum observation method on a single male individual. Observations were carried out once daily from 09:00 to 17:00 for seven consecutive days each week. Data were analyzed descriptively and quantitatively through ethogram presentation and frequency percentage calculations of behavioral occurrences. The results showed a dominance of arboreal locomotion behaviors: brachiation occurred 126 times (38.77%), climbing 47 times (14.46%), and descending 43 times (13.23%). Foraging and social behaviors were moderately observed feeding 27 times (8.31%) and playing 26 times (8.00%) while self-maintenance (grooming) occurred 13 times (4.00%) and resting 15 times (4.62%). Excretion frequency was low: urination 6 times (1.85%) and defecation 2 times (0.62%). These findings indicate that the enclosure structure supports natural arboreal behavior, but additional foraging stimulation and enrichment are needed to prevent boredom and enhance long-term welfare. Recommendations include improving environmental enrichment complexity, regular evaluation of vertical structures, and further research on Javan gibbon welfare standards in ex-situ conservation facilities.
