Development of Modified Kato Katz Kit as Laboratory Scale Prototype for Early Detection of Soil-Transmitted Helminths (STHs) Infection
Get PDFEarly detection of Soil-Transmitted Helminths (STHs) infection in laboratory medical facilities is one of the government's efforts in its elimination. Government regulations recommend Kato-Katz's quantitative method forthe diagnosis of STHs infection. Kato-Katz's domestic product is not availableyet. This research aims to create a laboratory-scale modified Kato-Katz kit for early detection of STHsinfection by fecal egg counts (FECs) in estimating the number of eggs per gram of stool (EPG).An experimental study was conducted to create a resin template, spatulas, and 3M-adhesive tape as a modified Kato-Katz Kit. 120 Kato-Katz thick smear preparations were done from 30 samples for modified and standard Kato-Katz with duplication. The amount of stool for each was weighed. All Kato-Katz thick smear microscopic examination was done at least 60 minutes by identifying the STHs eggs and counting them.The result for both methods showed no differences in EPG for Trichuris trichiura eggs p-value=0.012 (p<0.05), meanwhile the differences for Ascaris lumbricoides eggs p-value=0.156, and Hookworm eggs p-value=0.102 (p>0.05). Under microscopic examination, some A.lumbricoides eggs morphology was not visible because the adhesive in modified Kato-Katz blurry it, and the Hookworm fragile eggshells made it disappear within less than 60 minutes.The study concluded no difference in EPG for T.trichiura eggs by FECs betweenmodified Kato-Katzas this study product with the standard. It is recommended to improve modified Kato-Katz in further study, especially the adhesive tape, before using it as a quantitative toolforearly detection of STHs infection.
Analysis of Metabolite Levels, Secondary Minerals and Aloe Vera Formulation from Kalimantan Indonesia
Get PDFProducts from natural ingredients such as aloe vera must be high quality and meet standardization aspects. Determination of secondary metabolites and mineral levels is part of the standardization of natural product products. The dosage formula needs to be optimized to get the best formula based on evaluating the physical properties of the gel preparation. This study aimed to analyze the highest mineral and metabolite content between aloe vera from South Kalimantan and West Kalimantan, as well as the optimum formula for aloe vera gel based on its physical properties. The research method used is to perform sample preparation, extraction, analysis of minerals and secondary metabolites by spectroscopy. The data were analyzed descriptively, and the results showed that the content of iron, calcium, and zinc originating from West Kalimantan was 0.314 mg/g; 93.42 mg/g; 0.059 mg/g, while South Kalimantan 0.064 mg/g, 53.24 mg/g, 0.032 mg/g. The total phenolic, flavonoid, and anthraquinone levels from West Kalimantan were 0.512%, 1.31%, respectively, 2.28%, while those from South Kalimantan were 0.321%, 1.12%, 1.14%. The best formula for aloe vera gel is formula three, which has a darker color and meets the requirements of the physical properties of the gel. This study concludes that the highest mineral content in aloe vera comes from West Kalimantan, the highest secondary metabolite content also comes from West Kalimantan. And the best formula is the third formula with 20% natural dyes. Suggestions for further research are to examine the mineral content and secondary metabolites of aloe vera in various places in Indonesia so that the best aloe vera can be known
Influence of Diabetes on Morphometric Index of Ovarian Follicles in Streptozocin-Induced Rats
Get PDFThe study aimed to determine the effect of diabetes on follicle development by measuring the diameters of rats' ovarian follicles. The structure and function of many organs change by being affected by diabetes. The ovary is an essential organ of the reproductive system affected by diabetes. The size of the ovarian follicles and corpus luteum can also be affected by diabetes. For this reason, body mass, blood glucose level, and rat ovarian follicles, and corpus luteum diameters were measured in this study. Ten healthy female rats were kept as the control group. In the other rat group, experimental diabetes was induced with streptozotocin (STZ)(60 mg/kg). The rats in both groups were killed after 30 days and their ovaries removed. 5-6 µm sections were made using paraffin embedding techniques and stained with hematoxylin-eosin. On the fifth day of STZ administration to rats, the mass loss of rats was 10%, and the diabetogenic index was 330%. Compared with the control group, diameters of diabetic rats significantly decreased the diameter of the primordial, primary and Graafian follicles, and corpus luteum. The decrease in the diameter of secondary follicles of diabetic rats was not significant. The percentage shrinkage index was the highest in the corpus luteum with 37%. As a result, it can be said that diabetes influences the size of the ovarian follicles and especially the corpus luteum, thereby negatively affecting the ability to improve oocyte quality. Diabetes-related follicle diameter may shrink and cause infertility. It may be essential to measure the diameters of the follicles in vitro fertilization studies in patients with diabetes
Clinicopathological Study of Mucormycosis in Post Covid Patients, an Epidemic in Pandemic
Get PDFMucormycosis is an angio-invasive disease caused by saprophytic fungi of the order Mucorales. Mucormycosis has been established and recognized as a complication of the SARS-CoV-2 infection. Mucormycosis, well known as "black fungus" is creating an epidemic within a global pandemic. The use of different dose regimens, prominent steroids, and multiple comorbidities like Diabetes Mellitus and post-COVID could predispose to mucormycosis. The aim of the study was to study the increase in cases and morphological features of mucormycosis infection in hospitalized post-COVID patients. This prospective study was done for four months, from May 1st, 2021, to August 31st, 2021. All the suspected cases of mucormycosis specimens sent to the Department of Pathology, J.J.M. Medical College, Davangere, for histopathological diagnosis were considered. For microscopic examination, the collected samples were fixed in 10% formalin solution, processed, and stained with Haematoxylin and Eosin. Periodic Acid-Schiff special staining was done. Thirty cases of mucormycosis were collected from patients who had recovered from COVID-19. Mean age 63±12 (37-80) years with Male:Female ratio being 1.3:1. The mean duration between diagnosis of COVID-19 and development of symptoms of mucor was 23.5±10 (7–60) days. Rhino-orbital mucormycosis was the most typical presentation. Out of 30 cases, 28 cases (93.3%) were Type 2 Diabetes Mellitus, and 2 cases (6.6%)were nondiabetic. All patients received corticosteroids for the treatment of COVID-19. Trinity of COVID -19, Diabetes Mellitus, and Corticosteroid treatment was significant for the rise in mucormycosis cases. Mucormycosis is an invasive fungal infection and had seen a sudden surge during the second wave of COVID-19. In our study, most patients had a history of diabetes, and corticosteroid therapy with rhino-orbital mucormycosis was the most typical presentation. As the severity of the necrosis increases, the presence of fungal hyphae also increases, which leads to extensive destruction of tissue. Extra vigilance in immunosuppressed patients helps in reducing the morbidity and mortality due to mucormycosis in Post COVID era

The antibacterial test using the well diffusion method showed the best inhibition of bacterial growth in ethanol extract, with the largest inhibition zone of 24 mm at a concentration of 500 mg/ml. The study's conclusion was the extract of ethanol, ethyl acetate, petroleum ether and chloroform from the leaves of Dracontomelon dao (Blanco) Merr. & Rofe contains the same five secondary metabolites: flavonoids, alkaloids, saponins, tannins and triterpenoids. All types of extracts showed varying abilities to inhibit the growth of Escherichia coli. Further research is needed on the antibacterial properties of Dracontomelon dao (Blanco) Merr extract. & Rofe, especially on the active substance triterpenoid, which is the largest content in all types of extracts
Effect of Time and Temperature Variables on Prothrombin Time and International Normalized Ratio of Plasma in Patients in Gampaha, Sri Lanka
Get PDFGenerating accurate results for Prothrombin time (PT) and International Normalized Ratio (INR), PT/INR test is paramount in treatment monitoring. The diagnosis process measures how long it takes blood to clot. The main objective of this study was to determine the effect of storage time and temperature variables on PT and INR results in patients attending Hematologic clinics in Sri Lanka. This cross-sectional study was conducted during June and July 2021. PT was measured in the plasma samples, stored at different temperatures at baseline (0 hours), and then after 12 hours, 18 hours, and 24 hours after specimen collection. INR was calculated from each result, and the deviation percentage of PT and INR was calculated compared to the baseline result (0 hours). Then PT and INR percentage deviation is grouped as <10% and >10% to find biologically significant variations while paired t-test was performed to find statistical significance using GraphPad prism 8.4.3. At refrigerated temperature, both PT and INR results showed>10% variation once kept 24 hours, and this variation was statistically significant (p<0.01, Wilcoxon matched paired sign ranked test). The plasma specimens kept at laboratory temperature and specimen collection room temperature for 18 hours indicated >10% variation of PT and INR values, while these variations were significant at the same criteria above. These results suggest that the separated plasma could only be recommended to test up to 12 hours. Therefore, the laboratories that operate in the same climatic conditions can now use these results to plan the specimen collection accordingly
Effectiveness of Xylene and Mineral Oil in DNA Extraction from Formalin-fixed Paraffin-embedded Diffuse Astrocytic Tumor
Get PDFFormalin-fixed paraffin-embedded (FFPE) tissue is an important source of material for molecular analysis. In the anatomical pathology field, molecular testing is needed in certain tumors, such as astrocytic tumors, to confirm the diagnosis. Extracting DNA from FFPE material is still challenging. The first important step in the extraction process is deparaffinization. This study aims to compare two types of deparaffinization methods. The first method used xylene, and the second one used mineral oil. The results of this study can be used to develop a reliable protocol for DNA extraction from FFPE tissue. DNA from 28 FFPE diffuse astrocytic tumor tissue blocks was extracted. The quantity and A260/A280 ratio of the DNA was measured by spectrophotometer. PCR assays were performed to assess the suitability of extracted DNA for molecular analysis. The results showed that the xylene group has significantly higher DNA concentrations than the mineral oil group (p<0.01). In both groups, average and median A260/A280 scores were between 1.8-2.0. In PCR assay, both groups show a similar result (27 of 28 samples were successfully amplified). In conclusion, xylene and mineral oil can be used effectively as deparaffinization agents. Both methods generated good quality extracted DNA. The advantage of mineral oil is that it is non-toxic and has shorter hands-on time. Xylene is preferable for a small-sized sample because it produces a higher DNA yield
Utility of Neutrophil Lymphocyte Ratio (NLR) and Platelet Lymphocyte Ratio (PLR) as A Predictor of Mortality in COVİD-19
Get PDFCoronavirus-19 pandemic has stricken our world since December 2019; the disease, first reported in China, is now a pandemic. More than 400 million people have been affected, and 5 million people have succumbed to the disease. Hence, it is the need of the era to find readily available laboratory parameters to assess the mortality chances in these patients. Our study aims to determine the utility of NLR and PLR ratios as a predictor of severity and clinical outcome of COVID-19 patients.100 patients admitted to a tertiary care hospital in Karnataka, India, during the months April to July 2020 were studied. Only patients with a positive RT-PCR (Reverse Transcriptase Polymerase Chain Reaction) report for COVID-19 were included. Demographic data, comorbidities, and mortality status were collected from electronic hospital records. Lab parameters including- Total Count (TC), Absolute count of neutrophils and lymphocytes, platelet count were taken. NLR and PLR were derived from available lab parameters. Patients were categorized into varying severity depending on their SpO2 levels at admission. Neutrophil count (P=0.001) and NLR (P=0.002) were associated with an increased risk of mortality and disease severity. An increase in PLR ratio (P=0.05) shows a mild association with mortality but not with disease severity (P=0.096). In contrast, comorbidities, increasing age, and gender did not show any statistical significance for mortality. The presence of statistical significance concerning NLR and PLR should be utilized as an aid by clinicians to assess disease severity and chances of mortality. As new variants of the disease are uprising and a single therapeutic measure is not available currently for the treatment of COVID-19, clinicians should be well informed about how to monitor the disease in a cost-effective and easily accessible way to reduce the disease mortality and morbidity
The Platelet/Monocyte Ratio Before Treatment Predicts Prognosis in Solid Childhood Cancers
No full textThe prognostic value of thrombocytosis and inflammatory biomarkers in adult cancer patients has been the subject of many studies. This study investigated the role of platelet count and other inflammatory biomarkers in the prognosis of solid childhood tumours. The data of 176 pediatric patients diagnosed with solid tumours were evaluated retrospectively; 150 patients still under follow-up were included in the study. We examined the relationship between platelet count, platelet/neutrophil ratio (PNR), platelet/lymphocyte ratio (PLR) and platelet/monocyte ratio (PMR) at the time of diagnosis on survival. The mean age of diagnosis was 7.91 ± 5.75 years, and 60.7% were male. The mean platelet count of the patients was 424.326 ± 167197.32. The median (range) follow-up was 13 (1-68) months. Relapse was seen in 18% of the patients, and 9.3% died. The relationship between PMR and overall survival (OS) and event-free survival times (EFS) was statistically significant (p=0.002 and p=0.016, respectively). However, no statistically significant association was found for PLR or PNR. Overall survival and EFS were significantly poorer in this cohort in patients with high pretreatment PMR
Creatinine Clearance in Patients with Obstructive Sleep Apnea
Get PDFDuring an apnea, hemodynamic complications such as hypoxemia, a rise in systemic and pulmonary arterial pressure, and changes in heart rate occur in patients with obstructive sleep apnea (OSA). Potential mechanisms of OSA-associated renal dysfunction include renal hypoxia, hypertension, endothelial dysfunction. Hypertension is common in patients with OSA. This study aims to assess OSA patients' renal functions and investigate the creatinine clearance (CC) values across OSA patients with and without hypertension. The study included 530 individuals with OSA and 60 individuals with an apnea-hypopnea index (AHI) of 0.05). A statistically significant difference was detected in urea and creatinine levels between the OSA and control groups (p=0.005; p=0.012). Creatinine clearance decreases in patients with OSA in the presence of HT. Patients with OSA often experience cardiovascular disorders, and glomerular endothelial dysfunction occurs in OSA patients
