Can a combination of nanofat and freeze-dried human amniotic membrane enhance full-thickness wound healing? An animal study using rabbit models
Get PDFPrevious studies have explored nanofat stimulating tissue regeneration and maturation, promoting remodeling through its rich content of growth factors and stem cells; however, comprehensive data on its use in full-thickness wounds remains limited. The aim of this study was to evaluate the effectiveness of combining nanofat with freeze-dried human amniotic membrane (FDHAM) for treating full-thickness wounds in a rabbit model. An animal experimental study using a post-test control group design was conducted. Thirty-six male New Zealand white rabbits (Oryctolagus cuniculus) were randomly assigned to two groups: the experimental group (received a combination of nanofat and FDHAM) and the control group (received FDHAM alone). Each group was subdivided to evaluate effects on days 3 and 7. Macroscopic evaluations of wound healing, microscopic assessment of epithelialization and measurement of epidermal growth factor (EGF) levels in the wounds were conducted on days 3 and 7 post-injury. The present study indicated that the combination treatment significantly elevated EGF levels in the wounds on both days 3 and 7 (with p<0.001 for both assessment time points). The combination of nanofat-FDHAM did not significantly accelerate epithelialization on either day 3 or 7. This study highlights that combining nanofat with FDHAM did not significantly speed up epithelialization of full-thickness wounds within the first seven days; however, it notably increased EGF levels, suggesting that nanofat may enhance the wound's biological environment
Validity and reliability testing of the Shatri Sinulingga psychosomatic test (SSPT) questionnaire as a screening instrument for psychosomatic disorders in Indonesia
Get PDFThe incidence of psychosomatic disorders is increasing in Indonesia, and therefore screening instruments that are culturally appropriate for the Indonesian population are needed. The aim of this study was to assess the validity and reliability of the Shatri Sinulingga psychosomatic test (SSPT) questionnaire as a screening instrument for psychosomatic disorders in Indonesia. An analytic descriptive cross-sectional study divided into two stages (questionnaire formulation and distribution through the Psikosom.id application) was conducted in 2023. The validity test was carried out using the product moment technique, and Cronbach's alpha assessment was carried out to evaluate the reliability of the questionnaire. A total of 372 participants were included, with a mean age of 39.24 years old. The SSPT questionnaire scores had strong correlations with the scores of hospital anxiety and depression scale (HADS) (r=0.668; p<0.001) and the Symptom Checklist-90 (SCL-90) (r=0.674; p<0.001); and moderately correlated with the score of fatigue severity scale (FSS) (r=0.505; p<0.001) and Pittsburgh Sleep Quality Index (PSQI) (r=0.492; p<0.001). The correlation coefficient (r) value of each SSPT question ranged from 0.389–0.726, and all r higher than r table with an overall Cronbach’s alpha of 0.744. The SSPT questionnaire's strong predictive performance: had a sensitivity of 75.6% and specificity of 71.4% with an area under the curve (AUC) of 81% (95%CI: 76.6–85.4%; p<0.001) to HADS; sensitivity of 80% and specificity of 58.6% with an AUC of 75.1% (95%CI: 70–80.2%; p<0.001) to FSS; sensitivity of 64% and specificity of 67.5% with an AUC of 71.2% (95%CI: 65.4–77%; p<0.001) to PSQI; and had sensitivity of 78% and specificity of 67.4% with an AUC of 80.9% (95%CI: 76.6–85.3%; p<0.001) to SCL-90. The study highlights that the SSPT questionnaire is valid and reliable to be used as a screening instrument for psychosomatic disorders in Indonesia
Cryptogenic stroke in a 5-year-old girl with patent foramen ovale: A rare case
Get PDFStroke ranks among the prevalent factors contributing to child mortality. Cryptogenic stroke has been linked with patent foramen ovale (PFO), which has been suggested as a possible route for thrombus, gas bubble, or another particulate that comes through systemic venous circulation to the brain artery. Yet, the most effective approach for managing cryptogenic stroke involving a PFO remains uncertain. This case aims to report a PFO patient with complications of stroke. A 5-year-old girl was admitted to the emergency department at Dr. Zainoel Abidin Hospital, Banda Aceh, Indonesia, after experiencing numbness and weakness on her right side and a sudden onset of slurred speech three days before admission. Laboratory findings only showed leukocytosis, while coagulation tests were normal. Non-contrast brain CT revealed an occurrence of cerebral infarction in the left hemisphere. Transcranial Doppler showed no atherosclerosis in cerebral arteries, and carotid Doppler ultrasound results were reported normal. Transthoracic echocardiography showed a PFO with the right-to-left shunt. The patient was treated with an intravenous infusion of citicoline 250 mg twice daily, oral aspirin 80 mg daily, and oral mecobalamin 250 mg daily and was planned to undergo a PFO closure procedure. However, the patient’s parents rejected the plan to perform a PFO closure procedure. PFO has the potential to be a contributing factor to cryptogenic stroke among children. PFO closure followed by antiplatelet therapy for a couple of months has been shown to outperform medical therapy alone. However, additional evaluation should be done to cautiously consider the PFO closure procedure in children
Gender-specific reference values of dynamometric and non-dynamometric trunk performance in individuals with different body fat percentages: A preliminary study
Get PDFTrunk muscles maintain steady effort with adequate strength and endurance. When the muscle performance is subpar, it might cause lower back discomfort. No reference for trunk strength and endurance has been established previously. The aim of this study was to determine the normative reference values for dynamometric and non-dynamometric tests in people with various body fat percentages. Two hundred sixty-four participants aged 19–40 years old were recruited in this cross-sectional study. The Siri equation was used to calculate the individuals body fat proportions, which were divided into normal, high, and very high body fat for men and women. The Modified Sorenson's and the Back-Leg-Chest Dynamometric tests were utilized to measure muscular performance. The means of strength in females with normal, high, and very high body fat percentages were 27.39, 25.75, and 25.37 N/m2, respectively. The males in the same category had the means of 56.48, 51.79, and 60.17 N/m2, respectively. The highest mean of endurance in females was in those with normal body fat percentage (42.28), so did males (71.02). Our findingssuggest that males had higher trunk muscle strength and endurance than females, and normal-body-fat individuals had the greatest endurance regardless of gender
Effect of pegagan (Centella asiatica) nanoparticle coated with chitosan on the cytokine profile of chronic diabetic mice
Get PDFDiabetes is closely related to immune response problems when it occurs chronically. Pegagan (Centella asiatica) is a medicinal plant with active compounds. Madecassoside is beneficial in treating diabetes, and nanoparticle technology is expected to enhance the medicinal potential and availability of pegagan compounds. The aim of this study was to determine the effect of chitosan-coated pegagan nanoparticles on the cytokine profile of chronic diabetic mice, which included CD4+TNF-α+, CD8+TNF-α+, CD4+IFN-γ+, CD8+IFN-γ+ and IL-6+. An experimental study with a randomized complete block design (CRD) consisting of six treatments with seven replicates was conducted. The groups were: healthy mice as negative control; diabetic mice treated with distilled water as positive control and diabetic mice treated with nanoparticle coated with chitosan (NPC) 20 mg/kg, 30 mg/kg, 40 mg/kg, and metformin 130 mg/kgBW. The data were tested using one-way analysis of variance (ANOVA) with a significance level of 5% and continued with the Duncan’s multiple range test. The results showed that pegagan NPC could significantly reduce the relative number of CD4+TNF-α+, CD8+TNF-α+, CD4+IFN-γ+ and CD8+IFN-γ+ and IL-6 in the dose of 20 mg/kg, 30 mg/kg and 40 mg/kg (p<0.05). The treatment dose of 20 mg/kg reduced CD4+TNF-α+, CD8+TNF-α+, CD4+IFN-γ+, CD8+IFN-γ+ to the levels of healthy mice and a dose of 30 mg/kg could reduce IL-6 as in healthy mice. These findings suggest that chitosan-coated pegagan nanoparticles are a promising therapy for diabetes, as they have the potential to modulate the immune response associated with chronic diabetes
Comparison of RT-PCR cycle threshold values between individual and pooled SARS-CoV-2 infected nasopharyngeal swab specimens
Get PDFThe molecular reverse transcription-polymerase chain reaction (RT-PCR) testing of respiratory tract swabs has become mandatory to confirm the diagnosis of coronavirus disease 2019 (COVID-19). However, RT-PCR tests are expensive, require standardized equipment, and relatively long testing times, and the sample pooling method has been introduced to solve this issue. The aim of this study was to compare the cycle threshold (Ct) values of the individual sample and pooled sample methods to assess how accurate the pooling method was. Repeat RT-PCR examinations were initially performed to confirm the Ct values for each sample before running the pooled test procedure. Sample extraction and amplification were performed in both assays to detect ORF1ab, N, and E genes with a cut-off point value of Ct <38. Overall, there was no difference in Ct values between individual sample and pooled sample groups at all concentrations (p=0.259) and for all pooled sizes. Only pooled size of five could detect the Ct value in the pooled samples for all concentration samples, including low-concentration sample (Ct values 36 to 38). This study highlighted that pooled RT-PCR testing strategy did not reduce the quality of individually measured RT-PCR Ct values. A pool size of five could provide a practical technique to expand the screening capacity of RT-PCR
Black garlic exhibited hepatoprotective effect against monosodium glutamate-induced hepatotoxicity in animal model
Get PDFMonosodium glutamate (MSG) is commonly used as a flavor-enhancing agent in foods, and studies have demonstrated its toxic effects in animal models. Black garlic is known for its antioxidant and anti-inflammatory properties; however, there is a lack of studies on the potential hepatoprotective effect of black garlic ethanol extract (BGE) against MSG-induced hepatotoxicity in rats. The aim of this study was to investigate the hepatoprotective effects of ethanol extract of black garlic against MSG-induced liver damage in animal model. Twenty-five male Wistar rats were randomly assigned to five groups (n=5): negative control, MSG only, and MSG with three different doses of BGE. The MSG only and MSG with BGE groups were orally administered with 8 mg/kg MSG daily. After MSG treatment, the MSG with BGE groups received BGE orally at daily doses of 200, 400, or 600 mg/kg body weight for 16 consecutive days. Subsequently, the levels of serum liver enzymes aspartate aminotransferase (AST), alanine aminotransferase (ALT), interferon-gamma (IFN-γ), and cyclooxygenase-2 (COX-2) were measured. Our data indicated that the group treated with 200 mg/kg BGE had significant lower levels of AST and ALT significantly compared to the MSG-only group. The MSG-treated group had higher levels of the inflammatory markers COX-2 and IFN-γ, which were lowered by administration of 200 mg/kg BGE. In contrast, higher doses of BGE led to greater levels of COX-2 and IFN-γ compared to those in the MSG-only group. This study suggested that BGE might have hepatoprotective effects at low dose, potentially mitigating MSG-induced liver damage. However, the higher dose of black garlic extract did not alleviate inflammation, as shown by the higher levels of COX-2 and IFN-γ
Association between COVID-19 severity with liver abnormalities: A retrospective study in a referral hospital in Indonesia
Get PDFCoronavirus disease 2019 (COVID-19) is characterized by an acute respiratory infection with multisystem involvement and the association of its severity to liver function abnormalities is not well characterized. The aim of this study was to assess the association between the severity of COVID-19 patients and liver function abnormalities. This retrospective study included adult patients with confirmed COVID-19, which were classified as non-severe or severe according to World Health Organization guidelines. Liver function test results were compared between the severity groups. A total of 339 patients were included of which 150 (44.25%) were severe cases. The male-to-female ratio was 0.9:1 and 3:2 in the non-severe and severe groups, respectively (p=0.031). Aspartate aminotransferase (AST), alanine transaminase (ALT), and total bilirubin levels and acute liver injury (ALI) incidence were significantly higher in the severe group compared to non-severe group (p<0.001, p<0.001, p=0.025, p=0.014, respectively). In contrast, albumin levels were significantly lower (p=0.001). Multivariate analysis showed that ALI was significantly associated with human immunodeficiency virus (HIV) infection (odds ratio (OR): 5.275; 95% confidence interval (CI): 1.165–23.890, p=0.031), hemoglobin level (OR: 1.214; 95%CI: 1.083–1.361, p=0.001), and hypoalbuminemia (OR: 2.627; 95%CI: 1.283–5.379, p=0.008). Pre-existing liver diseases were present in 6.5% of patients. No significant differences were observed between the groups based on COVID-19 severity and ALI presence. Liver function test abnormalities, including ALI, are more prevalent in patients with severe COVID-19 infection. HIV infection, high hemoglobin levels, and hypoalbuminemia may be potential risk factors for ALI
Role of digital education through smartphones in improving knowledge among asthma patients: A preliminary study
Get PDFAsthma is a chronic inflammatory airway disorder and is among the top ten causes of morbidity and mortality in Indonesia, highlighting the need for effective management strategies. This study aimed to evaluate changes in asthma knowledge levels before and after using the "Paru Sehat" smartphone application for digital education. A quasi-experimental study using a pre- and post-test design was conducted over three months at the outpatient clinic of Universitas Sumatera Utara Hospital, Medan, Indonesia, among asthma patients aged over 18 years. The patients completed the Patient Asthma Knowledge Questionnaire (PAKQ) before installing the "Paru Sehat" application to establish baseline knowledge. Once a week, patients received reminders to access materials covering an asthma overview, peak flow meter use, medication differences, and management techniques. After four weeks of intervention, the participants' knowledge was reassessed using the PAKQ. Data were analyzed using either paired Student's t-test or Wilcoxon test to assess the improvement in knowledge. The results showed increases in knowledge about asthma in general, asthma triggers, and asthma diagnosis domains, with the median score in each domain rising by one point (p=0.003, p=0.001, and p=0.002, respectively). The asthma management domain exhibited the largest change, with a median increase of two points (p<0.001). The total scores increased by an average of five points (p<0.001), indicating an overall improvement in patient knowledge about asthma. The "Paru Sehat" application demonstrated significant potential in enhancing asthma knowledge across multiple domains. Further research is warranted to explore the long-term effectiveness of the application in diverse populations and settings, ultimately contributing to improved asthma management and patient outcomes
Molecular interaction analysis of ferulic acid (4-hydroxy-3-methoxycinnamic acid) as main bioactive compound from palm oil waste against MCF-7 receptors: An in silico study
Get PDFFerulic acid (4-hydroxy-3-methoxycinnamic acid) is a phytochemical compound that is commonly found in conjugated forms within mono-, di-, polysaccharides and other organic compounds in cell walls of grain, fruits, and vegetables. This compound is highly abundant in the palm oil waste. The aim of the study was to predict the anticancer activity of ferulic acid against the breast cancer cell lines (MCF-7) receptors through a computational analysis. MCF-7 receptors with PDB IDs of 1R5K, 2IOG, 4IV2, 4IW6, 5DUE, 5T92, and 5U2B were selected based on the SMILE similarity of the native ligand. Thereafter, the protein was prepared on Chimera 1.16 and docked with ferulic acid on Autodock Vina 1.2.5. The ligand-protein complex interaction was validated by computing the root mean square fluctuation (RMSF) and radius of gyration (Rg) through molecular dynamic simulation. In addition, an absorption, distribution, metabolism, excretion, and toxicity (ADMET) prediction was performed on ferulic acid using the pkCSM platform. The molecular docking revealed that the ferulic acid could interact with all receptors as indicated by the affinity energy <-5 kcal/mol. The compound had the most optimum interaction with receptor 2IOG (affinity energy=-6.96 kcal/mol), involving hydrophobic interaction (n=12) and polar hydrogen interaction (n=4). The molecular dynamic simulation revealed that the complex had an RMSF of 1.713 Å with a fluctuation of Rg value around 1.000 Å. The ADMET properties of ferulic acid suggested that the compound is an ideal drug candidate. In conclusion, this study suggested that ferulic acid, which can be isolated from palm oil waste, has the potential to interact with MCF-7 receptors
