Abstract

Status asthmaticus is a life-threatening acute asthma exacerbation that fails to respond to initial standard therapy and requires prompt, protocol-based emergency care. This article aims to determine the clinical status of asthma as a respiratory emergency: management in pediatric and adult populations. The article was compiled using a Systematic Literature Review (SLR) approach, combining current evidence and clinical guideline recommendations regarding the management of status asthmaticus in pediatric and adult populations. Status asthmaticus is a form of severe asthma exacerbation that is an emergency because it can lead to respiratory arrest and death if not treated promptly. Patients generally present with complaints of progressive shortness of breath, cough, wheezing, and signs of respiratory failure such as tachypnea, accessory muscle retractions, and in severe cases, decreased consciousness. Symptoms in children are usually more dramatic due to narrower airways, while in adults the main risks are respiratory muscle fatigue and ventilation complications. Initial management includes airway stabilization, oxygen administration, and immediate initiation of a short-acting bronchodilator (nebulized beta-agonist/MDI). If improvement does not occur, inhaled anticholinergics and systemic corticosteroids are added. Thus, in both children and adults, status asthmaticus requires early recognition, rapid treatment, and close evaluation until the condition is fully stabilized. Continuous monitoring with pulse oximetry and arterial blood gas analysis is emphasized as essential for detecting deterioration. Early recognition and rapid escalation following standard emergency pathways are crucial to reducing morbidity and mortality in both age groups.

Abstract

Decompression illness (DCI) encompasses two major diving-related disorders: decompression sickness (DCS) and arterial gas embolism (AGE). Both conditions are characterized by the formation of gas bubbles that act as the primary mechanism of tissue injury, resulting in overlapping clinical manifestations and similar therapeutic approaches. This study aims to review the pathophysiology, clinical presentation, diagnosis, and management of DCI that presents with stroke-like neurological symptoms. The method used was a literature review approach based on current evidence from recent scientific publications. Findings show that DCS occurs when dissolved inert gases, such as nitrogen, become supersaturated during ascent and form bubbles within tissues and the venous circulation. AGE typically arises from pulmonary barotrauma, allowing trapped gas to enter the pulmonary veins and reach the arterial circulation, with the brain as the most vulnerable target organ. DCI is considered a medical emergency requiring definitive management with hyperbaric oxygen therapy (HBOT). Neurological manifestations of DCI often resemble conventional ischemic stroke but demonstrate distinct clinical and temporal patterns related to pressure changes. Therefore, in addition to recompression therapy, patients may require standard acute stroke management. Prognosis depends heavily on the promptness of diagnosis and treatment, as early intervention is critical to preventing permanent neurological injury.

Abstract

Iron deficiency anemia remains a significant global health issue, particularly among young adults. Medical students are theoretically expected to possess superior nutritional literacy compared to the general population due to their academic exposure to metabolism and digestive systems. However, a gap often exists between theoretical knowledge and daily dietary practices. This article reviews the literature regarding the relationship between nutritional knowledge levels and iron intake adequacy. The review highlights that nutritional knowledge involves cognitive levels ranging from recalling information to evaluation. Iron metabolism is complex, involving heme and non-heme iron absorption, which is significantly influenced by enhancers and inhibitors. Despite having high nutritional knowledge, medical students' eating behaviors are increasingly determined by modern lifestyle factors, including social media trends and fast-food consumption, which may compromise iron intake. Conclusively, bridging the gap between knowledge and practice requires not just memorization but the application of balanced nutrition principles (Tumpeng Gizi Seimbang) to ensure optimal iron bioavailability.

Abstract

Smoking can cause health problems for both active and passive smokers because the toxic substances contained in it cause health problems, especially in the larynx, one of which is laryngeal cancer. Animal studies have shown histopathological changes in mice exposed to cigarette smoke, including increased immune cells and focal inflammation in these mice. The study aims to determine the relationship between cigarette smoke and the number of inflammatory cells, edema, hyperplasia, and dysplasia after exposure to cigarette smoke for 120 minutes in histopathological sampling at observations of 0, 10, 20, 30 and 40 days. This study used a true experimental design model with a post-test only group laboratory experimental design. The results of the study found a significant difference in the number of lymphocytes before and after exposure to cigarette smoke with p = 0.043. There was no significant change in the number of macrophages with p = 0.406 and eosinophils with p = 0.119. There were no histopathological changes, namely edema (p = 0.06), dysplasia (p = 0.126) and hyperplasia (p = 0.960). In conclusion, there is a relationship between cigarette smoke exposure and laryngeal histopathology in Rattus novergicus Rats.

Abstract

The development of a topical gel preparation with (Jatropha curcas L). joastic plant leaf extract and (Curcuma zedoaria) white turmeric aims to produce a product with optimal anti-inflammatory activity. This study involves the formulation of the gel with a combination of extracts from these two plants, which were extracted using ethanol as a solvent. Organoleptic tests for F1, F2, and F3 revealed a deep green gel with the distinctive odor of Jatropha leaves and White Turmeric, and a semi-solid gel. Homogeneity tests showed that F1, F2, and F3 were evenly distributed without any coarse grains. Meanwhile, pH tests for F1 (5), F2 (5.67), and F3 (6.33) met the pH standard for safe use on the skin. Viscosity tests for F1 (8.584cps), F2 (8.604cps), and F3 (8.666cps) indicated a good gel viscosity range. The spreadability test was conducted to measure the gel's ability to spread on the skin surface, while the adhesion test assessed the length of time the gel adhered to the skin with results of F1 5.23cm; F2 5.36cm and F3 5.71cm. The results of the F1 adhesion test were 3 seconds; F2 5 seconds and F3 9.33 seconds. Overall test results showed that the formulated gel had good physical properties, with an appropriate pH, stable viscosity, and satisfactory spreadability and adhesion. These findings suggest that the topical gel containing (Jatropha curcas L) and (Curcuma zedoaria) extracts holds potential as an alternative for topical anti-inflammatory treatment.

Abstract

Forest and land fires are recurrent in Indonesian tropical mountain savannas and threaten biodiversity, carbon stocks, and local livelihoods, yet spatially explicit burned-area information is still limited. This study aimed to evaluate the performance of the Burn Area Index (BAI) from Landsat 8 OLI–TIRS imagery for mapping the 2024 fire in Bukit Anak Dara, East Lombok. Burned and unburned pixels were classified by applying a two-class Otsu threshold to the ΔBAI histogram for the full scene extent. The resulting burned-area map was validated against high-resolution polygons obtained from visual interpretation of Sentinel-2A imagery and against fire hotspots from the SiPongi+ system. Compared with Sentinel-2A polygons, the ΔBAI–Otsu method produced a burned-area estimate of 275.49 ha versus 318.87 ha from the reference and achieved an overall accuracy of 0.97, precision of 0.94, recall of 0.81, and an F1-score of 0.87. Validation against hotspot data yielded lower performance (overall accuracy 0.87, precision 0.40, recall 0.41, F1-score 0.41), reflecting conceptual and spatial-scale differences between point-based active-fire detections and patch-based burned-area mapping. Burned pixels were concentrated on west–northwest facing slopes dominated by dry savanna, highlighting the role of topography and fuel characteristics in fire spread. Overall, the results therefore indicate that the ΔBAI–Otsu approach is a rapid, transparent, and reproducible tool for post-fire burned-area mapping in tropical mountain ecosystems and has strong potential for routine operational monitoring.

Abstract

The prevalence of students experiencing stress in Indonesia ranges from 36.7-71.6%. One method that can be used to overcome stress is alternative therapy, such as deep breathing. Therefore, this researcher aims to analyze the difference in stress levels before and after being given a breathing relaxation technique in nursing students at the Adventist University of Indonesia in facing final semester exams. This type of research is an experimental study using the One-Group Pretest-Posttest Design. The results found that the initial stress levels of students showed variations ranging from normal to very severe categories, so that respondents had varying stress conditions before the intervention was carried out. There was a decrease in stress scores after being given the deep breathing relaxation technique, as seen from a decrease in the average post-test score compared to the pre-test. The results of the Wilcoxon Signed Rank Test showed a p-value of 0.059, so the decrease in stress was not statistically significant. Overall, deep breathing has potential as a stress management method, but its effectiveness in this study has not been proven significant.
