Clinician-Ordered Peripheral Smear Review by a Pathologist Has Low Clinical Utility-A Reference Laboratory Perspective.

Background: Clinician-ordered peripheral smear review by pathologist (CPSR) is commonly ordered and has been recommended for decades. However, the clinical utility of this labor-intensive test in the reference laboratory has not been examined. The objective of this study is to assess hematologic abnormalities identified in CPSR orders and to correlate them with complete blood count (CBC) and laboratory-derived smear review (LDSR) in the reference laboratory.

Early Introductions of Candida auris Detected by Wastewater Surveillance, Utah, USA, 2022-2023.

Candida auris is considered a nosocomial pathogen of high concern and is currently spreading across the United States. Infection control measures for C. auris focus mainly on healthcare facilities, yet transmission levels may already be significant in the community before outbreaks are detected in healthcare settings.

Differential pathogenicity and lethality of bubonic plague (1720-1945) by sex, age and place.

COVID-19 brought back to the attention of the scientific community that males are more susceptible to infectious diseases. What is clear for other infections-that sex and gender differences influence both risk of infection and mortality-is not yet fully elucidated for plague, particularly bubonic plague, although this knowledge can help find specific defences against a disease for which a vaccine is not yet available. To address this question, we analysed data on plague from hospitals in different parts of the world since the early eighteenth century, which provide demographic information on individual patients, diagnosis and course of the disease in the pre-antibiotic era.

Extensively Drug-Resistant Pseudomonas aeruginosa Outbreak Associated With Artificial Tears.

Background: Carbapenemase-producing, carbapenem-resistant Pseudomonas aeruginosa (CP-CRPA) are extensively drug-resistant bacteria. We investigated the source of a multistate CP-CRPA outbreak.

Methods: Cases were defined as a US patient's first isolation of P.

Age estimation using tooth cementum annulations: bias and sources of inaccuracy.

Background: Counting the tooth cementum annulations (TCA) is a method for estimating the age at death of adults by sections of their tooth root. The objective of this study was to assess the precision of counting the cementum incremental lines and the congruence between known age and age estimates. Possible factors affecting the accuracy of the estimate were also analyzed.
