Antibiotic consumption and resistance: a 3-years ecological study for four critical groups of bacteria in a general regional hospital
Full text linkPseudomonas aeruginosa, Acinetobacter baumannii, Escherichia coli, and Klebsiella pneumoniae are the most critical groups of multi-drug resistant (MDR) bacteria that cause a threat in hospitals. This study identified the trend of antibiotic consumption, antibiotic resistance pattern, and the relationship between antibiotic consumption and antibiotic resistance in a critical group of bacteria in a general regional hospital. This ecological study was based on retrospective data from inpatient databases in a general regional hospital over three years (2017-2019). The trend for annual antibiotic consumption over 2017-2019 was defined as defined daily doses/100 bed-days. The relationship between total antibiotic consumption and the percentage of antibiotic resistance among four isolated critical bacteria was explored in time series analysis and linear regression. The most frequently used antibiotic was ampicillin (220.33 DDD/100 bed-days), ciprofloxacin (126.86 DDD/100 bed-days), and ampicillin-sulbactam (126.34 DDD/100 bed-days). There was a significant relationship between antibiotic consumption (ampicillin, ampicillin-sulbactam, ceftazidime, gentamicin, amikacin, and ciprofloxacin) in DDD/100 bed-days and antibiotic resistance in E. coli, K. pneumoniae, and P. aeruginosa (p<0.05) but not statically significant in A. baumannii (p=0.062). The annual usage fluctuated or remained stable, with no statistically significant trends change. The relationship between antibiotic consumption and antibiotic resistance was significant in three out of four critical groups of bacteria
Sunscreen effectivity and physical characterization of avocado oil in nanoemulsion using isopropyl myristate variations
Full text linkUnsaturated fatty acids in avocado oil can help reduce erythema brought on by prolonged UV-B exposure. The effectivity of sunscreen absorption into the skin will be enhanced by the use of isopropyl myristate (IPM) in nanoemulsion. The purpose of this study was to determine the physical characteristics and sunscreen effectiveness of avocado oil nanoemulsion (AVN) modified with IPM. 1% (FI), 3% (FII), and 5% (FIII) IPM variation were used to make AVN with 5% oil. The AVN were tested for physical characteristics such as organoleptic, pH, viscosity, rheology, particle size and polydispersity index (PI). The products were also tested for sunscreen effectivity by in vitro and Minimum Erythemal Dose (MED) method. The data obtained were analyzed statistically. The results showed that the AVN was pale yellow and clear with transmittance percentage were 96%. The rheogram showed that the products were newtonian. The pH values range were from 6.62 to 6.66; viscosity 1.65-1.84 dPa.s; particle size < 17 nm, zeta potential was in range of -30,54±1,72 to -37,85±3,11 and PI < 0.5 for all formula. In vitro SPF values were 16.43 ± 4.50 (FI), 16.27 ± 4.20 (FII) and 17.88 ± 3.20 (FIII) (p >0.05), and categorized as ultra protection. MED value were 12.28 ± 1.34 (FI); 12.51 ± 1.68 (FII); and 13.22 ± 1.84 (FIII) (p< 0.05) and categorized as maximum protection. Isopropyl myristate increased the sunscreen product's MED value without changing its physical characteristics
Enterobacter hormaechei: an endophytic bacterium found in Avocado Peel (Persea americana Mill.) with antioxidant properties
Full text linkAvocado peels (AVP) are renowned for their potent antioxidant properties, making them highly effective in preventing oxidation and free radical formation. Endophytes, microorganisms residing within plant tissues, have demonstrated the ability to produce novel compounds with remarkable biological activities. These bioactive compounds are sometimes even more potent than those found in their host plants. This study explores the potential of endophytes from avocado peels as rich sources of antioxidant compounds. AVP samples are collected, surface-sterilized, and segmented before being cultured in growth media. The bacteria are then isolated, purified, and subjected to ethyl acetate extraction to evaluate their antioxidant activity using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) microassay. Samples demonstrating favorable antioxidant properties undergo molecular identification through 16S rRNA gene sequencing. Four bacterial strains are successfully isolated, with only the APK4 strain exhibiting significant antioxidant activity with an IC50 value of 302.3 μg/mL. Molecular analysis and phylogenetic tree construction reveal that APK4 is closely related to the Enterobacter hormaechei species, with a percent identity value of 99.93%. These findings highlight the potential of active metabolites from endophytic bacteria in AVP extracts as promising lead compounds for the development of novel drugs, nutraceuticals, and cosmetic ingredients
Interprofessional education applied in first-year and third-year health students: cross-sectional study
Full text linkHealth professions work together to provide the best service in health care facilities by collaborating with patients, families, worker and the community. Interprofessional education (IPE) were practice of collaboration between two or more students from different health profession programs. The purpose of study was to compare IPE results from first and third year batches. The two batches included 345 first-year students and 460 third-year students, from three different health disciplines, including medicine, pharmacy, and public health. These students met for four weeks to increase interprofessional collaboration, improve communication skills, foster respect and increase knowledge of the various roles each discipline, especially case management, conflict management and team work. Before IPE program, the students were given pre-questionnaire to assess their prior understanding of IPE. Each group of first-year students presented the outcomes of their discussions in the fourth week, while the third-year students created a poster about the subject and presented it in the second week. The students complete the program and post-questionnaire after their presentation. The International Collaborative Competencies Attainment Survey served the development the IPE questionnaire (ICCAS). The result of pre-IPE domains’ score revealed substantial disparities in the team work domain, with third-year students score was lower than the first students, whereas first-year students had the highest score in the most of IPE categories, unless collaboration and conflict management (p>0.05). The post-IPE domains’ score showed significant differences in all of the domains. Most of the IPE domains had higher score in first year students, excluding communication and team work

The highest inhibition on the stat3 and smo pathways was shown by the beta compound eudesmol, with binding energy and Ki values of -6.05 kcal/mol, -7.57 kcal/mol, and 36.48 uM, respectively; 2.81 uM
DNA-based detection of Rat in the meatballs product using a real-time polymerase chain reaction method
Full text linkThe meat-based products are highly susceptible to counterfeiting, primarily due to high consumer demand of meat derivative products, such as meatballs. This demand creates opportunities for food fraud by specific industries, including adulterating meat with non-halal species, such as rats. This research aimed to detect rat meat contamination in meatball samples from the Indonesian local market using Real-time Polymerase Chain Reaction (RT-PCR). The RT-PCR amplification involved an initial denaturation step at 95°C for 3 minutes, followed by denaturation at 95°C for 15 seconds, and annealing/extension at 60°C for 1 minute. The rat-specific probe primer included in the kit produced an increasing curve in the External Positive Control (EPC) with a Ct value of 27.22, and no amplification occurred in the Negative Control (NTC). The analysis of 30 samples from meatball vendors yielded negative results, as there was no increase in the FAM (rat) curve, indicating that none of the meatballs were contaminated with rat DNA
The effect of recompression and concentration of polyvinylpyrrolidone (PVP) K-30 on the quality of paracetamol tablets
Full text linkQuality control during production is a critical process that ensures the quality of the tablets until it reaches the consumer. In the pharmaceutical industry, there is a possibility of reworking, including tablet recompression. Nevertheless, the recompression process may have affected the potential of PVP K-30 as a binder to reunite the particles of tablet ingredients. However, the difference of PVP K-30 concentration might be resulting in the differences of granule and tablet characteristics. This study aims to determine whether there is an effect of recompression and the difference of PVP K-30 on the quality of paracetamol tablets. The effect of recompression and the difference of PVP K-30 was seen based on whether there is a significant different on physical properties of the mixture of tablet ingredients (mixture’s flow rate and compressibility) and the tablets (compatibility and tablet’s hardness, friability, and disintegration time) from the formula with a concentration of 2% w/w and 4% w/w PVP K-30 after experiencing 2 times of recompression. Paracetamol tablets were made by wet granulation method through the stages of granulation, lubrication, physical properties testing of the mixture, tablet compression, physical properties testing of tablets, crushing, and recompression. Data analysis was performed statistically using the Shapiro-Wilk normality test, followed by two-way Analysis of Variance (ANOVA) or Kruskal-Wallis test and Post Hoc Mann Whitney test. The results showed there was an effect of recompression and different concentration of PVP K-30 on the potential of PVP K-30 as a binder as seen from significant differences in the physical properties of the mixture and tablets in each test group

Full text linkCoronavirus-2 (SARS-Cov-2) is a virus that attacks the respiratory system and causes the Covid-19 pandemic. After the pandemic, prevention and appropriate therapy research continue to be carried out to anticipate the emergence of more dangerous viruses. In line with the culture of consuming herbs that has arisen due to the effects of the pandemic, in this study, an insilico screening was carried out for essential oil compounds produced by ginger and thyme herbs which have been widely consumed by the public. The aim of the research was to find the essential oil content that has the most potential as an antiviral against coronavirus-2. The research method was carried out in silico, including ligand preparation, receptor and method validation, and analysis of ligand-receptor binding interactions using the AutoDoc 4.2.6 program. As a comparison, a study was conducted on remdesivir and favipiravir, which have been used as antivirals. The three components that have the most potential based on the calculation of the free energy value, were determined by the ADMET parameters using the Admet lab 2.0 program. The results showed that the three components in the essential oil exhibited better interactions when compared to remdesivir and favipiravir at the 3-Cl protease and spike glycoprotein receptors. The results of the insilico study and ADMET prediction test showed that of the three most potent compounds, lamda-farnesen was the most potent and safe to us
