Abstract

In a health center-level morbidity data report by the Gorontalo City Health Office in 2020, the prevalence of fungal-related skin diseases attained 4.76 percent (476 cases), including 56 cases of tinea pedis. One of the variables in athlete's foot is a workplace and type(s) of work that fail to satisfy basic health guidelines. In the case examined by this study, the patient was a butcher employed locally in a small shop. This study aims to use a variety of parameters to describe the non-dermatophyte fungi that cause butcher's toe infections. Fungus characteristics were performed macroscopically and microscopically. The observations were used to describe the characteristics of the fungus, which were then analysed descriptively with reference to the identification manuals book. Non-dermatophyte fungi such as Aspergillus sp., Rhizopus sp., Candida albicans, were identified in the study findings. Aspergillus sp., Rhizopus sp., Candida albicans and other types of fungi such as Metarhizium anisopliaea. This study demonstrates that non-dermatophyta fungal infections may be the source of butchers' tinea pedis.

Abstract

The Polymerase Chain Reaction (PCR) technique is extensively employed in molecular biology to precisely detect Mycobacterium tuberculosis. Prior to conducting PCR, extracting of high-quality genomic Deoxyribonucleic Acid (DNA) is crucial to ensure accurate and reliable results. The primary objective of this study is to conduct a comparative analysis of the purity and concentration of M. tuberculosis DNA acquired through the utilization of the boiling method and the spin column extraction methods. A descriptive comparative research design was employed, utilizing a sample of 16 sputum specimens that had previously been confirmed as positive for M. tuberculosis through Acid-Fast Bacteria (AFB) examination and Molecular Rapid Test (MRT). The extraction of DNA was carried out using the boiling method and the spin column method. Subsequently, the concentration and purity of the extracted DNA were assessed using the NanoDrop Spectrophotometer, and the results were compared. The obtained yield of M. tuberculosis DNA isolates through the boiling method ranged from 9.6 ng/µL to 1258.7 ng/µL, with an average purity value of 1.23. Conversely, for the spin column method, the concentration of M. tuberculosis DNA isolates ranged from 8.7 ng/µL to 207.8 ng/µL, with an average purity value of 1.83. In conclusion, there is a significant difference between the purity and concentration of M. tuberculosis DNA extraction results using the boiling method and spin column methods.

Abstract

Escherichia coli is a leading cause of Urinary Tract Infections (UTIs) in Indonesia, with approximately 180,000 cases reported annually. The more cases of UTIs, the more PCR diagnosis is needed with an accurate, fast, simple, and economical DNA isolation method. However, currently, there is no DNA purification stage from protein and RNA contaminants in the boiling DNA isolation method. This study aimed to investigate the impact of incorporating Proteinase-K and RNase into the boiling DNA isolation method on the purity and concentration of E. coli’s DNA during isolation. The boiling method involved heating to 95°C – 100°C bring to cell lysis and release of cellular components, including DNA. Urine samples were artificially contaminated with E. coli at different McFarland standards (0.25, 0.5, and 1). The boiling DNA isolation method was then performed and then analyzed for purity and concentration using a NanoDrop spectrophotometer. This study demonstrated a positive correlation between Proteinase-K and RNase concentrations used in the boiling DNA isolation method and the subsequent increase in DNA purity and concentration. An increase in DNA purity and concentration was obtained even though it was not statistically significant compared to that without Proteinase-K and RNase addition, with p-values of 0.245 for DNA purity and 0.353 for DNA concentration. Further research is recommended with higher Proteinase-K and RNase concentrations in the boiling DNA isolation method to achieve improved purity and concentration of E. coli DNA. Such enhancements could improve PCR amplification and help diagnose E. coli-related UTIs.

Abstract

Non-polar clearing agents have the ability to dissolve breast adipose tissue. While fat dissolution occurs during the clearing process, careful monitoring of adipose cell membranes mis crucial due to their impact on the behavior of breast cancer cells and disease progression. Xylol is a widely employed clearing agent. However, its toxicity and prolonged clearing time necessitate the exploration of alternatives. In this context, methyl salicylate emerges as a viable substitute. It is non-polar nature facilitates efficient fat dissolution, leading to quicker tissues clarification. This study adopted a quasi-experimental method, utilizing 24 pieces of breast tissue as the sample. These tissue sample were divided into six groups according to the treatment regimen. The treatment groups involved breast tissue clearing using xylol for 2x60 minutes at room temperature, methyl salicylate for 2x30 minutes at room temperature, and methyl salicylate at 60°C for 20 minutes, 30 minutes, 2x20 minutes, and 2x30 minutes. The quality of breast tissue slides was assessed by analyzing the color contrast between the nucleus and cytoplasm using ImageJ software, along with the clarity of adipose cell cell membrane using microscopy. The results indicated that prolonged exposure at high temperature resulted in poor quality breast tissue slides. Conversely, tissue clearing with methyl salicylate for 2x30 minutes at room temperature exhibited excellent contrast between the nucleus and cytoplasm, as well as clear adipose cell membranes. Further study is warranted to explore the applicability of methyl salicylate as a clearing agent in tissues with lower fat content.

Abstract

Sigma Metrics, as a quality indicator, have been widely applied in clinical laboratories to assess the performance of analytical methods. Described in the document Clinical and Laboratory Standards Institute (CLSI) EP15- A3, the use of target values can be sourced from certified reference standards, survey materials from the Proficiency Testing (PT)/External Quality Assessment (EQA), materials used in inter-laboratory quality control programs and internal quality control materials with predetermined targets. This research aims to determine whether there is a difference in the sigma metrics between the bias derived from the manufacturer's target value and those from the peer group source in the External Quality Assurance Services (EQAS) program. The research methodology employed is descriptive comparative analysis, utilizing the results of material inspection data for 15 internal quality control parameters of Clinical Chemistry over a span of 2 years at the Pramita Laboratory in Bandung. The calculation of the sigma metrics commences with computing the coefficient of variation (CV), and the appropriate Total Error aalowable (Tea) sources for each parameter are determined beforehand using the TEa algorithm. The research findings indicate a difference between the sigma metrics derived from the manufacturer's target value and those from the EQAS-peer group target value, accounting for 33% or 10 parameters out of the total parameters with 2 levels of inspection are calculated on the sigma scale. However, in 67% or 20 parameters out of the total parameters, no such difference is observed. Bias associated with the target value from the manufacturer and the EQAS peer group shows no significant difference, suggesting that the laboratory can utilize pre-existing target values confidently.

Abstract

Dengue fever is endemic in Sri Lanka. Liver damage is common in dengue fever. Understanding the pattern change of the liver profile and haematological parameters is crucial for managing dengue patients and minimising liver damage. The purpose of this study was to determine the pattern change in liver profile and the haematological parameters of dengue patients. Sixty apparently healthy volunteers and 169 acute dengue patients aged 20 or older had their blood samples examined. Liver enzymes, albumin, protein, bilirubin, white blood cell count, platelet count, haematocrit, and haemoglobin were measured. There was an increase in aspartate aminotransferase (105.6 IU/L), alanine aminotransferase (82.6 IU/L), and gamma-glutamyl transferase (68.9 IU/L), which were 3.4, 3.9, and 3.2-fold higher, respectively, than those of the control group, suggesting liver injury. Eighty-four percent of patients had raised levels of aspartate aminotransferase, and 74% of patients had elevated levels of alanine aminotransferase, indicating the prominence of aspartate aminotransferase over alanine aminotransferase. The presence of a positive correlation between the levels of aspartate aminotransferase and alanine aminotransferase indicates that the elevation of enzymes is primarily due to a single cause, liver injury. White blood cells and platelet counts were significantly lower. Platelet count demonstrated a negative correlation with both haematocrit and haemoglobin in dengue patients. In conclusion, aspartate aminotransferase was identified as the most significant marker of dengue-associated liver injury, followed by alanine aminotransferase. Low platelet and white blood cell counts were the major unfavourable changes in dengue patients' haematological characteristics.

Abstract

Conjunctivitis is the most common eye disease, characterized by contextual inflammation, which can be caused by bacteria. The diagnosis of conjunctivitis is established based various factors, including the patients’s medical history, onset of eye symptoms, non-ocular symptoms, previous disease history, family medical history, allergies, and physical examination of the eyes, which may include assessments of visual acuity and vision field. Some cases of conjunctivitis require laboratory examinations to confirm the diagnosis. These may include cytological examination with Giemsa staining, Chlamydia Diagnostic Test, Nucleic acid amplification tests (NAATs) or Polymerase chain reaction (PCR), and microbiological tests. Microbiological examination helps identify the bacteria responsible for conjunctivitis and aids in treatment by prescribing antibiotics to suppress the growth of the infecting bacteria. While identification tests are not routinely performed, researchers often seek to determine the specific type of bacteria causing conjunctivitis infections, which may require several laboratory tests. Bacterial virulence plays a significant role, with genetic mutations potentially leading to severe infections of varying severity. Virulence genes encode proteins that express pathogenic properties. The species responsible for conjunctivitis can be definitively identified definitively through microbiological examination, utilizing methods such as the 16S Ribosomal RNA Sequencing (rRNA) technique, known for its accuracy and speed. This study aims to analyze the results of rRNA sequencing in cases of acute bacterial conjunctivitis caused by 16S rRNA genotyping. The research employed an exploratory metholodolot, with the results analyzed using the The Basic Local Alignment Search Tool (BLAST) tracking program database on the National Center for Biotechnology Information (NCBI) website. The findings revealed that Sphingomonas paucimobilis encoded the 16S rRNA using Universal Primary 27 F and 1492 R, obtained in a sequence size of 1351bp. The isolate demonstrated similarities to Sphingomonas paucimobilis.

Abstract

COVID-19 (Corona Virus Disease 2019) was a life-changing pandemic with impact on social, environmental, health, and economic issues. Various inflammatory and hematological biomarkers studied individually or in combination in the literature have shown significant results with regard to COVID-19 pathology, severity, and prognosis. Yet the question of interest is how covid-19 inflammatory cascade impacts the interlink between the biomarkers during different stages. This study aims to retrospectively analyse ferritin, albumin, alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin, direct bilirubin, blood urea nitrogen (BUN), creatinine, D-dimer, Lactate Dehydrogenase (LDH), C Reactive Protein (CRP) and Interleukin-6 (IL-6) levels between two groups based on COVID-19 severity.  A retrospective cross-sectional study was conducted with laboratory data of COVID-19 patients admitted at Sri Ramachandra Medical College Hospital, India. The sample size was 104 [Group1: severe disease, n=52; Group-2: mild disease, n=52]. After normality testing, data were compared between the two groups followed by correlation analysis between the variables. A p<0.05 was considered statistically significant. On comparison, Group 2 (severe COVID-19 disease) showed significant difference in the levels of all the biomarkers (p<0.005) except Creatinine (p<0.128) when compared with Group 1 (mild COVID-19 disease). Significant correlation was obtained between all biomarkers (p<0.005) except creatinine. The correlation analysis primarily explains the inflammatory cascade involved in disease. Ferritin appears to have a standalone effect on disease severity, progression, organ dysfunction. This understanding can be used to provide better and more timely care.

Abstract

The majority of the published studies have described the alterations in platelet count and platelet indices in both severe and non-severe Coronavirus Disease 2019 (COVID-19). However, their association with COVID-19 mortality remains unclear. In the present study, our aim is to determine the temporal evolution of platelet count and its parameters between survivors and non-survivors, as well as their potential association with clinical outcomes. This cross-sectional study included 1118 inpatients (≥18 years old) diagnosed as SARS-CoV-2 positive by a Real-Time Polymerase Chain Reaction (RT-PCR) and hospitalized between May 1st, 2020 and November 1st, 2020. Data of complete blood count (CBC) parameters evaluated on different days after admission was gathered and the median value of each CBC parameter was considered for assessing the difference between survivors and non-survivors. There was statistically significant variation between survivors and non-survivors for platelet count [p<0.001, mean difference-80 x 109/L], mean platelet volume [p<0.001, mean difference- 0.7 fL], platelet distribution width [p<0.001, mean difference-2.5%] and platelet-lymphocyte ratio [p<0.001, mean difference-123.8]. Thrombocytopenia occurred more commonly in deceased patients compared to survivors. Platelet count, Mean Platelet Volume (MPV) and Platelet Distribution Width (PDW) differed significantly between survivors and non-survivors, revealing distinct trends indicating their importance in the management of COVID-19 patients. These cost-effective parameters can be easily obtained from a CBC.
