Multivariate logistic regression analysis showed that the LEPR Gln223Arg Arg/Arg genotype was an independent risk factor for NAFLD; the Arg/Arg genotype, compared with the Gln/Gln genotype, was associated with a 2.09-fold increased risk for NAFLD (P = .036, odds ratio = 2.09 [95% CI = 1.31-5.95]).Conclusions: We found that the LEPR Gln223Arg Arg/Arg genotype was independently associated with a more than 2-fold rise in biopsy-proven NAFLD risk.

We sought to determine the prevalence of this practice among reference laboratory clients and characterize the impact of pandemic-driven supply shortages.Methods: This cross-sectional study surveyed 354 client laboratories to understand specimen collection practices in specific clinical environments and how these practices may have been affected by supply chain shortages. Data analysis by descriptive statistics was performed in Qualtrics.Results: A total of 138 laboratories took the survey (39% response rate) with 57% indicating that their ED performed rainbow draws. Of these, 16% have a formal policy regarding rainbow draws, and 76% of respondents indicated that their institution was required to modify practices due to pandemic-driven supply shortages. A total of 19% indicated they routinely collect multiple urine aliquots for add-on testing.Conclusion: Rainbow draws and collection of urine aliquots in the ED for add-on testing are relatively common practices, with few institutions maintaining formal policies regarding the practice. Pandemic-driven supply chain shortages affected a majority of respondent laboratories and local cost-benefit analysis regarding extra specimen collection is recommended to limit waste of laboratory resources.","PeriodicalId":94124,"journal":{"name":"Laboratory medicine","volume":" ","pages":"585-589"},"PeriodicalIF":0.0,"publicationDate":"2024-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11371900/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140023870","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The timeframe was from January 1, 2020, to December 31, 2020. A retrospective chart review was used to collect data for the following: patient-provider encounter notes, patient demographics, provider demographics, differential and final diagnosis, and laboratory test results. Data analysis include stratification of categorical variables and calculation of cost savings.Results: For the 12-month period, this study found 2567 (9.3%) of all amylase and lipase tests to be unnecessary. Amylase tests (1881; 73.2%) made up the most unnecessary tests followed by lipase tests (686; 26.7%). An analysis of test-ordering behavior by providers revealed that 81.5% of all unnecessary tests were ordered by MDs.

Liquid biopsy has become a revolutionary strategy for cancer diagnosis and prognosis prediction. This study aims to investigate the diagnostic and prognostic value of circulating exosomal glypican-1 (GPC-1) in PC.Methods: We systematically searched relevant studies. For diagnostic accuracy, pooled sensitivity and specificity and the area under the summary receiver operating characteristic curve (AUC) were calculated. Regarding prognostic value, hazard ratios (HRs) and 95% CIs for overall survival (OS) were summarized by using a random-effects model.Results: We found 8 studies that examined the diagnostic value of circulating exosomal GPC-1 in PC, and 3 studies that investigated its prognostic value. Pooled sensitivity and specificity were 0.88 (95% CI, 0.65-0.97) and 0.86 (95% CI, 0.72-0.94). The AUC was 0.93 (95% CI, 0.90-0.95). Prognostic analysis showed that higher levels of circulating exosomal GPC-1 were associated with poorer OS in PC patients, and the combined HR for OS was 4.59 (random-effects model, 95% CI = 1.17-18.03, P = .022). The results of both studies were robust and neither had publication bias.Conclusion: Circulating exosomal GPC-1 may be used as a diagnostic and prognostic biomarker for PC. However, this result needs to be validated by further research using a larger sample size.","PeriodicalId":94124,"journal":{"name":"Laboratory medicine","volume":" ","pages":"543-552"},"PeriodicalIF":0.0,"publicationDate":"2024-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140103109","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}

Adherence to these guidelines proves to be challenging, and the nationwide screening rates are still considered suboptimal. The aim of this study was to assess and improve the screening rates at our large pediatric center.Methods: A 4-year retrospective audit of OGTT completion among pediatric patients with CF of age ≥10 years who are not yet diagnosed with diabetes was conducted. A collaborative working group was formed to identify the barriers to screening and formulate a quality improvement plan, which was monitored and evaluated for a 9-month period.Results: Diabetes screening rates determined by OGTT completion at our center showed a gradual decline during the COVID-19 pandemic from 2019 to 2022. Following the implementation of the quality improvement plan during the summer of 2023, there was a marked increase in OGTT ordering compliance by providers as well as test completion by patients. Notably, the fractional OGTT completion rate rose from 45% during the preintervention phase (January-April 2023) to 70% during the postintervention phase (May-September 2023).Conclusion: Diabetes screening in pediatric patients with CF can be effectively improved by refining practices related to patient experience, care coordination, and laboratory testing strategies.","PeriodicalId":94124,"journal":{"name":"Laboratory medicine","volume":" ","pages":"580-584"},"PeriodicalIF":0.0,"publicationDate":"2024-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139934882","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}
