Abstract
Background and objectives: Coronavirus disease 2019 (COVID-19) is a global health problem. Laboratory professionals are at a higher risk of contracting the disease during the COVID-19 pandemic. This study was conducted to examine lab professionals' perceptions and satisfaction with organizational processes during the COVID-19 outbreak.
Methods: This cross-sectional survey was carried out on 53 medical laboratory professionals working at laboratories in Tripoli (Libya) between November 2020 and January 2021. Data were collected via face-to-face questionnaire. Responses to questions were scored based on a five-point Likert scale (1=strongly disagree, 2= disagree, 3=neutral, 4=agree and 5=strongly agree). Data were presented as frequency and percentages using the Microsoft Excel 2016.
Results: Most participants were female (81.2%) and with less than five years of work experience (39.6%). The majority of respondents (79.3%) had a bachelor’s degree. Most healthcare workers (75.5%) were unaware whether the lab would provide medical care if they were tested positive for COVID-19, while 13.2% of them perceived that they will get free medical care. Owing to social distancing, 20 subjects (37.7%) felt that their social activities have been altered during break time. Only 3.7% of the participants believed that their motivation level decreased due to the COVID-19 outbreak.
Conclusion: The outcomes of this study provide laboratorians’ perspective in the COVID-19 crisis as well as specific lessons for future unpredicted crises.

Abstract
Background and objectives: Turnaround time (TAT) is an important quality indicator for benchmarking laboratory performance. Delay in TAT may affect patient safety; thus, continuous monitoring and analysis of laboratory workflow is mandatory. This study was designed to improve the TAT of two biochemistry laboratories serving in tertiary care teaching hospitals (multispecialty and super-specialty) through the application of quality tools namely quality failure reporting, the Fishbone model, and process mapping.
Methods: First, TAT was defined for routine (four hours) and urgent samples (two hours). Then, TAT failureincidents in 2018-2019 were analyzed using the Fishbone model. The process map of TAT was studied and made more value streamed and lean after removal of waste steps.Corrective action plans were prioritized and implemented for potential causes with more adverse outcomes. Pilot solutions were implemented for six months and TAT failures incidents were reanalyzed.
Results: The quality failure in TAT reporting was reduced by 22% (from 34% to 12%) for urgent samples and by 19% (from 27% to 8%) for routine samples after the implementation of quality tools in multispecialty hospital laboratory. In the super-specialty hospital laboratory, the improvement was more profound and the TAT percentage achieved after the corrective actions was 96.57% and 98% for urgent and routine samples, respectively.
Conclusion: Implementation of quality failure reporting culture along with quality tools led to significant improvement in TAT and higher quality laboratory performance in terms of efficiency, reliability, and increased patient safety.

Abstract
Background: ‘M’ proteins or paraproteins refer to immunoglobulins that are produced by clonal plasma cells and are a characteristic feature of monoclonal gammopathies. Routine electrophoresis on agarose gel and immunofixation can be used to detect immunoglobulin paraprotein (M-protein). We aimed to evaluate the performance of agarose gel electrophoresis alone and in combination with immunofixation for detecting serum M-proteins.
Methods: One hundred and twenty-three patients suspected of paraproteinemia were evaluated. Routine serum protein electrophoresis (SPE) and immunofixation electrophoresis (IFE) protocols were performed. Data from SPE, and SPE-IFE (gel images and electrophoretograms) were collected and reviewed.
Results: 21% cases were confirmed using the SPE-IFE combination, and among them, 33% had positive light chain (λ) only on IFE. Similarly, nine cases with biclonal gammopathy on SPE were characterized by IFE.
Conclusion: IFE can be a confirmatory test in cases where SPE results are not reliable and it can be a complementary test when characterization of the M protein detected on SPE is required.

Abstract
Background: Acute ischemic stroke occurs when blood clots obstruct blood vessels within the brain. Platelets (Plts) are integral to the pathophysiology of stroke. This research aimed to explore the relationship between Plt quality and Plt indices in the context of acute ischemic stroke.
Methods: This cross-sectional investigation involved 100 patients diagnosed with acute ischemic stroke at Kosti Teaching Hospital and Alyammama Hospitals. The diagnosis was confirmed using brain CT imaging and electrocardiography (ECG). Blood samples were collected in EDTA-containing tubes within 24 hours following the commencement of treatment and were subsequently analyzed for Plt count, mean Plt volume (MPV), Plt distribution width (PDW), and plateletcrit (PCT) utilizing a hematological analyzer. Data were analyzed using GraphPad Prism software.
Results: Platelet counts negatively correlated with PDW [r=-0.074, P=0.459; R=-0.023, P=0.815], MPV [r=-0.130, P=0.194; R=-0.081, P=0.417], and diastolic blood pressure [r= -0.023, P=0.818; R= -0.024, P=0.805]; and positively correlated with PCT [r= 0.103, P=0.308; R=0.143, P=0.155] and diastolic blood pressure [r=0.022, P=0.823; R= 0.008, P=0.932]. Moreover, PDW positively correlated with systolic blood pressure [r=0.105, P=0.298; R= 0.147, P=0.148] and diastolic blood pressure [r=0.146, P=0.145; R=0.173, P=0.084]. Based on Spearman but not Pearson correlation, PDW showed a negative correlation with PCT [r=-0.005, P=0.959; R=0.010, P=0.929].
Conclusion: The study shows a correlation between Plt count and indices in ischemic stroke patients. The research also presented evidence concerning the relationship between diastolic and systolic blood pressure and Plt counts and indices.

Abstract
Background: Carbapenems are broad-spectrum β-lactam antibiotics, often reserved as last-line treatment for infections caused by multidrug-resistant (MDR) Gram-negative bacteria. Carbapenemase producing organisms (CPOs) pose a serious public health threat, contributing to severe healthcare-associated infections and increased mortality rates. This study aimed to determine the prevalence of CPOs and their antibiotic resistance patterns in isolates from burn and wound infections.
Methods: A total of 250 clinical samples (140 wound swabs and 110 burn swabs) were collected from hospitalized patients in Kirkuk and Sulaimaniyah hospitals between January and July 2023. Specimens were cultured on MacConkey agar and cetrimide agar and incubated at 37°C for 18–24 hours. Bacterial identification and antimicrobial susceptibility testing were performed using the BD Phoenix™ M50 system, while carbapenemase production was confirmed using the BD RAPIDEC® CARBA NP assay.
Results: Among the isolates, 27 (38.02%) were confirmed as carbapenemase-producing and exhibited multidrug resistance. The distribution was as follows: Pseudomonas aeruginosa (44.44%, 12 isolates), Escherichia coli (33.33%, 9 isolates), Enterobacter cloacae (18.51%, 5 isolates), and Klebsiella pneumoniae (3.7%, 1 isolate). Notably, CP-P. aeruginosa and CP-K. pneumoniae showed the highest resistance, being resistant to 15 antibiotics across seven different classes.
Conclusion: This study reveals a high prevalence of MDR CPOs in burn and wound infections, likely due to antibiotic misuse or overuse. The findings highlight the urgent need for novel therapeutic strategies to combat carbapenem-resistant pathogens, which are associated with increased global morbidity and mortality.
