Several studies were reported that a low level of serum albumin associated with a high risk of cardiovascular diseases (CVDs) mortality. Therefore, the present study aimed to investigate serum albumin levels and find out the association between serum albumin and CVDs and their correlation with cardiovascular risk factors. Methods: This was a cross-sectional study. Patients with confirmed CVDs were enrolled in this study while patients with CVDs plus acute or chronic liver and intestinal diseases were excluded in this study. Data were collected and analyzed by using SPSS version 21. P-value (two-tailed) < 0.05 was considered statistically significant. Results: A total of 400 subjects were enrolled, out of which 200 healthy control (male 125 and female 75) and 200 patients with CVDs (male 130 and female 70). The mean level of total protein, albumin, globulin, and HDL-C were statistically (p<0.005) lower while TC, TG, and FBS were statistically (p<0.005) higher in CVDs sub-jects in compared to healthy control. The serum albumin was lower in 35 (17.5%) of patients with CVDs, out of which 19 (9.5%) were male and 16 (8.0%) were female. Serum albumin showed a statistically significant negative correlation with age (p=0.000) and a positive correlation with TC (p=0.000). In multinomial logistic regression analysis, model-I, II, and III showed a statistically significant (p<0.05) association between serum albumin with CVDs. Conclusion: This study concluded, low serum albumin was found in patients with CVDs and it was significantly associated with CVDs. Therefore, measurement of serum albumin can be performed routinely in patients with CVDs.","PeriodicalId":185857,"journal":{"name":"Annals of Clinical Chemistry and Laboratory Medicine","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121841926","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These organisms are resistant to many antibiotics by intrinsic and acquired mechanisms making infections difficult to treat. Regular surveillance of infection and antibiotic resistance patterns is necessary for selection of appropriate antibiotics for treatment. \u0000Methods: Non repeating Pseudomonas spp isolated from all clinical samples during the year 2017-2019 were included in the study. Identification of Isolates were done by standard conventional tests and antibiotics sensitivity test was done by Kirby-Bauer disk diffusion method following the CLSI guidelines, 2017. \u0000Results: A total of 42,545 specimens comprising of sputum, blood, pus, urine, body fluids and endotracheal tubes were processed during the entire 3 year period. There was significant increase (p-value <0.05) in yearly isolation rate of Pseudomonas spp i.e. 141(7.95%), 197(12.14%) and 303(15.69%) isolates in the year 2017, 2018, and 2019 respectively. Resistance rates of the isolates to cefoparazone sulbactam, Piperacillin Tazobactam, and Tobramycin was significantly decreasing (p-value <0.05). Overall resistance to ceftazidime (66.13%) was alarming.

The controlled use of antimicrobials is important for national and international policymakers to draw guidelines on its use. Assessing AMR in meat-producing industry is essential to track emerging resistant pathogens that are common between animals and humans. In this study, we have aimed to investigate the prevalence of bacteria in meat products and the antimicrobial resistance pattern in those isolates.\u0000Methods: This study is a quantitative, observational study, where we collected meat samples (n=118) from shops, in Banepa and Dhulikhel Municipality. The samples were cultured in appropriate media for isolation of bacteria. Subsequently, AMR pattern was studied through antibiotic susceptibility test using Kirby Bauer Disc Diffusion method.\u0000Results: In our study, only two sites, out of 48, did not have any pathogenic bacteria. There were total of 113 iso-lates from 118 samples. E. coli (62.8%), Enterococcus (14.1%), Klebsiella pneumoniae (11.5%), were the most prevalent bacteria in processed samples including MRSA (4%). Additionally, 81.6% of the isolated E. coli were resistant to Ampicillin and 60.5% to Ciprofloxacin and 35% to Gentamycin. 43.6% of all isolated E. coli, 100% of all Klebsiella, 100% of all Enterobacter and 25% of all Citrobacter were multi-drug resistant. The resistance was mostly observed against Ampicillin (83.3%), followed by resistance against Ciprofloxacin (64.4%), Gentamycin (58.8%), Ceftazidime (38.8%), with the lowest resistance against Sulbactam/Cefoperazone (3.3%).\u0000Conclusion: E. coli was the most prevalent organism in meat samples. Multi-drug resistance was also most common in E. coli with resistance against Ampicillin, Ciprofloxacin and Gentamycin. Therefore, we recommend for more controlled use of antibiotics in animal rearing industry and more hygienic environment at meat vendors.","PeriodicalId":185857,"journal":{"name":"Annals of Clinical Chemistry and Laboratory Medicine","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130933462","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Evidences from the ancient civilizations including the Egyptian, Sumerian, Babylonian and Eastern Civilizations such as Vedic cultures support the use of urine as an index of physical and mental well-being.

Modern day tech-niques such as molecular biology, immunolo-gy, and mass spectrometry with high resolu-tion microscopy have taken up urinalysis to explore the genetic predisposition to inherited diseases and tumor studies besides the routine diagnostics. So, variation occurs in urinalysis from the simple routine analysis, microscopic examination to highly sophisticated and ad-vanced automated analytical techniques.

Disease modifying antirheumatic drugs have become the mainstay of management in rheumatoid arthritis. Among these drugs, methotrexate the most frequently used agent has a proven anti-inflammatory action and is known to slow down the progression of the disease. Hence the present study is undertaken to evaluate the effect of methotrexate on the oxidant and antioxidant status in patients with rheumatoid arthritis on methotrexate.Methods: A total of 40 rheumatoid arthritis patients and 40 controls were enrolled for the study. The rheumatoid arthritis patients were further divided into patients on methotrexate (group I) and patients without methotrexate (group II). The lipid peroxidation index -Malondialdehyde and total antioxidant activity, superoxide dismutase and glutathione levels were analyzed in all the participants.Results: A significant increase in total antioxidant activity (p = 0.048) and decrease in lipid peroxidation (p = 0.04) was found in methotrexate treated arthritis patients compared to patients without methotrexate. A significant negative correlation (p=0.01) was found between MDA and total antioxidant activity in both groups of patients whereas, the antioxidant enzyme superoxide dismutase was positively correlated with lipid peroxide levels. Conclusion: In conclusion low dose methotrexate seems to act as an effective anti-inflammatory drug and may also play an important role in minimizing the oxidative stress in rheumatoid arthritis. Serum total antioxidant activity is significantly raised in subjects with altered liver function profile.","PeriodicalId":185857,"journal":{"name":"Annals of Clinical Chemistry and Laboratory Medicine","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129493975","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
