The objective of this study is to investigate the effect of antibiotics on gut composition in children aged 3–5 years receiving antibiotics compared to children who did not receive antibiotics. A total of 54 participants aged 3–5 years were included in this multi-centric cohort study. Participants were divided into two equal groups, that is the treatment-experienced group (Group 1, n = 27, antibiotic) and the treatment-not-experienced group (Group 2, n = 27, non-antibiotic). Stool samples of study participants were collected on days 0 and 5 (± 1 day) and analyzed using 16Svedberg ribosomal ribonucleic acid (16S rRNA) gene sequencing. The Kruskal-Wallis H-test and Benjamini-Hochberg FDR correction were applied to determine the differentially abundant pathways across the zones using Statistical Analysis of Metagenomic Profiles (STAMP) (v2.1.3). A non-significant increase in the mean abundance of the Phyla Bacteroidota, Proteobacteria, Actinobacteria, and Verrucomicrobiota was observed in both groups from day 0 to day 5. An alteration in the Firmicutes/Bacteroidetes ratio was observed. A significant (P < 0.05) abundance of genus Enterobacteriaceae, Enterococcaceae, and Lactobacillaceae was observed in the participants with antibiotic treatment. The relative abundance of families Enterococcus, Lactobacillus, Sellimonas, Ruminococcus, Torques, and Eggerthella groups was observed to be significantly higher (P < 0.05) in participants with antibiotic treatment. Beta-diversity indices revealed significant differences at group and subgroup levels regarding the bacterial counts. It was observed that a short-term course of 5 days of antibiotic usage is associated with altered microbial abundance and diversity.","PeriodicalId":16149,"journal":{"name":"Journal of Laboratory Physicians","volume":"126 3","pages":""},"PeriodicalIF":1.1,"publicationDate":"2023-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139146185","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}

Red blood cell cholinesterase (RBC-ChE) and serum cholinesterase (serum-ChE) levels are used for predicting outcomes. There is a paucity of literature studying the RBC-ChE levels in OP poisoning and comparing it with the serum-ChE levels. Methods This is a longitudinal study assessing the outcome in OP poisoning patients using the RBC-ChE and serum-ChE levels. Both enzyme levels are compared and correlated for adult patients presenting within 24 hours of consumption of the OP compound. Sensitivity and specificity are measured. Results Of the 99 OP poisoning patients included, 20 patients did not survive, and 23 patients required ventilatory support. At admission, RBC-ChE (median, interquartile range [IQR]) was significantly different between survivors (45.2 [30.5–60] U/g Hb) and nonsurvivors (6.3 [4.2–13.4] U/g Hb), while serum-ChE (median, IQR) was not statistically different (p = 0.061) between survivors (350 [247–670]) and nonsurvivors (290 [182–415.8]). Similarly, RBC-ChE was significantly different between patients requiring a ventilator and those not requiring a ventilator (6.8 vs. 44.2 U/g Hb), whereas the serum-ChE values measured on admission were not significantly different for patients requiring a ventilator versus those not requiring a ventilator (290 vs. 348 U/L; p = 0.119). At the cutoff of 20 U/g Hb, RBC-ChE had 90.5% sensitivity and 91% specificity in predicting mortality. Kaplan–Meier survival showed the probability of survival decreased to nearly 50% if the time to reach the hospital was ≥4 hours.

Existing guidelines emphasize the importance of timely notification, but protocols may vary. This study evaluated the effectiveness of the protocol for reporting critical results in the biochemistry laboratory of a tertiary care hospital and proposed alternative protocols for improvement. Materials and Methods Data were collected over a 6-month period, including the total number of investigations, critical values detected, parameters analyzed, and clinical departments involved. Quality indicators such as turnaround time (TAT), unsuccessful reporting rates, and clinical actions taken were assessed. Statistical analysis was performed using Microsoft Excel. Results Out of 390,000 investigations, 0.5% had critical values. Serum potassium (55.9%) had the highest frequency of critical values, followed by sodium, calcium, and glucose. The emergency department received the highest number of critical alerts. The success rate of critical result reporting within 1 hour was 86.8%, while unsuccessful reporting accounted for 10.7%. The causes of unsuccessful reporting included outpatient requests and delayed intimation due to patient transfers. Corrective action was taken in 91% of cases, with documentation primarily in nurse charts. Conclusion Evaluation of the protocol for reporting critical results identified areas for improvement. Recommendations included revising the critical value list, reducing TAT through process optimization and automation, enhancing staff training and awareness, fostering interdisciplinary collaboration, and maintaining incident records. Implementing these changes can enhance compliance, reduce errors, and improve patient care.","PeriodicalId":16149,"journal":{"name":"Journal of Laboratory Physicians","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135478334","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}

Cancer Antigen-125 (CA-125) individually possesses limited specificity for differentiating adnexal masses. The present study aimed to evaluate the Human Epididymis Protein 4 (HE4), Risk of Ovarian Malignancy Algorithm (ROMA), and Risk of Malignancy Index (RMI) for ameliorating sensitivity and specificity for differentiating benign from malignant adnexal masses. Materials and Methods This study was conducted on 96 preoperative women with suspected adnexal mass (patients) and 48 healthy females without adnexal mass (controls) for the duration of 2 years. Both study participants were divided into two groups, pre- and postmenopausal. CA-125 and HE4 were done using commercially available kits. ROMA% and RMI were calculated. We validated their performances using histopathology as the gold standard. The statistical analysis was done using SPSS 21, Kruskal–Wallis, and Tukey's tests. The best cutoff points to best values of sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were also evaluated. Results For differentiating benign from malignant masses in the premenopausal group, the sensitivity, specificity, PPV, NPV, and area under the curve (AUC) were 93.7%, 78.3%, 65.2%, 96.6%, 0.892 for CA-125; 87.5%, 83.7%, 70%, 93.9%, 0.926 for HE4; 93.7%, 70.2%, 57.6%, 96.2%, 0.927 for ROMA; and 68.7%, 86.4%, 68.7%, 86.5%, 0.916 for RMI.

The present study focuses on the expression of cyclooxygenase-2 (COX-2), P53, vascular endothelial growth factor (VEGF), and nitric oxide synthase (NOS) and their relationship with the growth and angiogenesis of tobacco-related malignancies of the oral cavity, esophagus, lungs, and stomach. It further evaluates the carcinogenic action of nicotine and examines whether COX-2 and NOS-2 overexpression is responsible for tumor growth and associated angiogenic VEGF expression via its receptor. Material and Methods A cross-sectional study on 140 biopsies, resected specimens of cancer of oral cavity, esophagus, stomach, and lungs, was done. Immunohistochemical evaluation for p53, COX-2, VEGF, and inducible NOS was done. Relevant statistical analysis was applied for the significance of the findings. Results Immunohistochemical evaluation of pattern of expression of COX-2, NOS-2, VEGF, and p53 was done in both tobacco- and nontobacco-associated cases. The results of the present study revealed an upregulation of COX-2, NOS-2, VEGF, and p53 in all the malignancies. Conclusion The present results indicated that p53 protein accumulation and increased expression of COX-2, NOS-2, and VEGF might be responsible for carcinogenesis and tumor aggressiveness by enhancing angiogenesis. A possible significant effect of nicotine on COX-2 and P53 expression in tumorigenesis is revealed. These data might have important implications for the therapeutic use of COX-2, NOS-2, and VEGF inhibitors as well as of p53 gene therapy in future anticancer therapeutic strategies in tobacco-related malignancies.","PeriodicalId":16149,"journal":{"name":"Journal of Laboratory Physicians","volume":"118 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136015309","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}

Thus, the aim of this study was to observe the changes in platelet and erythrocyte parameters between diabetics and nondiabetics and to evaluate these changes in relation to glycemic control. Materials and Methods This cross-sectional study was performed in Mohammed VI University Hospital, Marrakech, Morocco, from January 2020 to July 2021. A total of 307 Moroccan patients were enrolled in this study, which included 222 diabetic patients and 85 nondiabetics. The diabetic patients were divided into two groups A (hemoglobin A1c [HbA1c] ≥ 6.5%) and B (HbA1c < 6.5%) according to their glycated hemoglobin levels (HbA1c). Biological parameters were processed as per the standard technique. Data analysis was performed using SPSS statistical software. Results A significant difference was mentioned regarding mean corpuscular volume (MCV) (p < 0.001), red blood cell distribution width (RDW) (p < 0.001), and volume/platelet count (p = 0.023) between diabetics and nondiabetics. MCV and RDW were lower in group B than group A (p = 0.004; p = 0.04), while MPV was higher (p = 0.342). RDW significantly and negatively correlated with HbA1c in diabetic population (r = –0.182; p = 0.006). On the other hand, a significant and positive correlation between MPV and HbA1c was mentioned (r = +0.184; p = 0.006). Conclusion Our study showed that RDW and MPV correlate with HbA1c in T2DM and can be used as a reproducible and inexpensive means to ensure proper control of glycemic status. Further studies are warranted to define specific RDW and MPV values predictive of complication risk in the diabetic population.","PeriodicalId":16149,"journal":{"name":"Journal of Laboratory Physicians","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135149176","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}

In cases with a vague history, postmortem ancillary investigation can also help to establish or rule out potential causes of death, such as underlying medical conditions or environmental factors. These investigations may include various laboratory tests, such as toxicology, histology, microbiology, and genetic analysis, as well as radiological imaging studies. This information not only helps in ascertaining the cause and manner of death but also helps in establishing the legal connotations in any medicolegal case. This is a case of a young woman allegedly 18 years brought for a medicolegal autopsy. She had been feeling unwell for a few days before her death, experiencing vomiting, weakness, and fatigue. Although no underlying disease was diagnosed, she was advised to take a pregnancy test. Fifteen days later, she died at home continuing to feel unwell. Upon autopsy, the young woman was found to be emaciated, and revealed a male fetus, of 4 to 5 months of gestational age, in her uterus. A radiological examination of bones conducted postmortem revealed that the age of woman was approximately 15 years old.
