- Abstract
Incomplete documentary evidence, variable biomolecular preservation, and limited skeletal responses have hindered assessment of acute infections in the past. This study was initially developed to explore the diagnostic potential of dental calculus to identify infectious diseases, however, the breadth and depth of information gained from a particular individual, St. Louis Individual (St.LI), enabled an individualized assessment and demanded broader disciplinary introspection of ethical research conduct. Here, we document the embodiment of structural violence in a 23-year-old Black and/or African American male, who died of lobar pneumonia in 1930s St. Louis, Missouri. St.LI exhibits evidence of systemic poor health, including chronic oral infections and a probable tuberculosis infection. Metagenomic sequencing of dental calculus recovered three pre-antibiotic era pathogen genomes, which likely contributed to the lobar pneumonia cause of death (CoD): Klebsiella pneumoniae (13.8X); Acinetobacter nosocomialis (28.4X); and Acinetobacter junii (30.1X). Ante- and perimortem evidence of St.LI's lived experiences chronicle the poverty, systemic racism, and race-based structural violence experienced by marginalized communities in St. Louis, which contributed to St.LI's poor health, CoD, anatomization, and inclusion in the Robert J. Terry Anatomical Collection. These same embodied inequalities continue to manifest as health disparities affecting many contemporary communities in the United States., (© 2022. The Author(s).)

- Abstract
Objectives: Given the recent debate challenging the contribution of cytology in cervical screening, we evaluated results of liquid-based cytology (LBC) and human papillomavirus (HPV) testing in cotesting preceding cervical cancer (CxCa) and precancer diagnoses in a national, heterogeneous population., Methods: We assessed the results of cotesting, performed by Quest Diagnostics, in 13,633,071 women 30 years and older, tested 2010 to 2018. Cotest results preceding CxCa or precancer diagnoses were analyzed and stratified by histopathology., Results: Among all screening results, 1,615 cotests preceded 1,259 CxCa diagnoses, and 11,164 cotests preceded 8,048 cervical precancer diagnoses. More women who were subsequently diagnosed with CxCa within 1 year were identified by the LBC result than by the HPV result (85.1%, 1,015/1,193 vs 77.5%, 925/1,193). Among all women with CxCa, the overall rate of nondetection was 13.1% (212/1,615) for cotesting results (LBC negative/HPV negative) and this rate increased substantially when testing exceeded 12 months compared to within 1 year prediagnosis of either CxCa or precancer., Conclusions: Analysis of 9-year cotest results from a national reference laboratory confirms the value of LBC element in cotesting. This supports that LBC/HPV cotesting enhances screening for the identification of CxCa in women 30 years and older, more so than LBC or HPV alone within cotesting., (© American Society for Clinical Pathology, 2020.)

- Abstract
Screening for cervical cancer with cytology testing has been very effective in reducing cervical cancer in the United States. For decades, the approach was an annual Pap test. In 2000, the Hybrid Capture 2 human papillomavirus (HPV) test was approved by the U.S. Food and Drug Administration (FDA) for screening women who have atypical squamous cells of underdetermined significance (ASCUS) detected by Pap test to determine the need for colposcopy. In 2003, the FDA approved expanding the use of the test to include screening performed in conjunction with a Pap test for women over the age of 30 years, referred to as "cotesting." Cotesting allows women to extend the testing interval to 3 years if both tests have negative results. In April of 2014, the FDA approved the use of an HPV test (the cobas HPV test) for primary cervical cancer screening for women over the age of 25 years, without the need for a concomitant Pap test. The approval recommended either colposcopy or a Pap test for patients with specific high-risk HPV types detected by the HPV test. This was based on the results of the ATHENA trial, which included more than 40,000 women. Reaction to this decision has been mixed. Supporters point to the fact that the primary-screening algorithm found more disease (cervical intraepithelial neoplasia 3 or worse [CIN3+]) and also found it earlier than did cytology or cotesting. Moreover, the positive predictive value and positive-likelihood ratio of the primary-screening algorithm were higher than those of cytology. Opponents of the decision prefer cotesting, as this approach detects more disease than the HPV test alone. In addition, the performance of this new algorithm has not been assessed in routine clinical use. Professional organizations will need to develop guidelines that incorporate this testing algorithm. In this Point-Counterpoint, Dr. Stoler explains why he favors the primary-screening algorithm, while Drs. Austin and Zhao explain why they prefer the cotesting approach to screening for cervical cancer., (Copyright © 2015, American Society for Microbiology. All Rights Reserved.)

- Abstract
Background: In the United States, human papillomavirus (HPV) and Papanicolaou (Pap) testing (cotesting) for cervical screening in women ages 30 to 65 years is the preferred strategy, and cytology alone is acceptable. Recently, a proprietary automated test for identifying high-risk HPV types for primary cervical screening was approved by the US Food and Drug Administration. The objective of the current study was to document extensive cervical screening among these screening options., Methods: To investigate the sensitivity of various testing options for biopsy-proven cervical intraepithelial neoplasia grade 3 or worse (≥ CIN3) and cancer, the authors reviewed 256,648 deidentified results from women ages 30 to 65 years at the time of cotest who had a cervical biopsy specimen obtained within 1 year of the cotest., Results: A positive cotest result was more sensitive (98.8%; 4040 of 4090 cotests) for diagnosing ≥ CIN3 than either a positive HPV-only test (94%; 3845 of 4090 HPV-only tests) or a positive Pap-only test (91.3%; 3734 of 4090 Pap-only tests; P < .0001). A positive Pap-only result was more specific (26.3%; 66,145 of 251,715 Pap-only tests) for diagnosing ≥ CIN3 than a positive HPV-only test (25.6%; 64,625 of 252,556 HPV-only tests) or a positive cotest (10.9%; 27,578 of 252,558 cotests; P < .0001). Of 526 cervical cancers, 98 (18.6%) were HPV-only negative, 64 (12.2%) were Pap-only negative, and 29 (5.5%) were cotest negative., Conclusions: Compared with HPV-only testing, cotesting was more sensitive for the detection of ≥ CIN3 in women ages 30 to 65 years. The current data suggest that approximately 19% of women with cervical cancer may be misdiagnosed by an HPV-only cervical screen. It is important to consider these data as the guidelines for cervical cancer screening undergo revision.

- Abstract
Context: The College of American Pathologists (CAP) conducted a national survey of gynecologic cytology quality assurance (QA) practices. Experts in gynecologic cytology were asked to join 5 working groups that studied the survey data on different aspects of QA. Evaluating the survey data and follow-up questions online, together with a review of pertinent literature, the working groups developed a series of preliminary statements on good laboratory practices in cytology QA. These were presented at a consensus conference and electronic voting occurred., Objective: To evaluate a set of QA monitors in gynecologic cytology. Working group 1 evaluated (1) monitoring interpretive rate categories for Papanicolaou tests (Pap tests), (2) concordance of cytotechnologist and pathologist interpretations before sign-out, and (3) turnaround time for Pap tests., Data Sources: The statements are based on a survey of gynecologic cytology QA practice patterns and of opinions from working group members and consensus conference attendees., Conclusions: The outcomes of this process demonstrate the current state of practice patterns in gynecologic cytology QA. Monitoring interpretive rates for all Bethesda System categories is potentially useful, and it is most useful to monitor interpretive rates for cytotechnologists individually and in comparison to the entire laboratory. Laboratories need to determine what level of discrepancy between cytotechnologist and pathologist interpretations of Pap tests is important to track. Laboratories should consider formalizing procedures and policies to adjudicate such discrepant interpretations. Turnaround time should be monitored in gynecologic cytology, but individual laboratories should determine how to measure and use turnaround time internally.

- Abstract
Objective: This study aimed to follow a large group of US women with negative computer-imaged liquid-based cytology (LBC) and positive high risk (hr) HPV DNA results., Methods: Negative LBC and positive hrHPV cases were identified between July 1, 2005 and December 31, 2009. Cytologic and histopathologic follow-up results, repeat HPV results, and prior history were analyzed., Results: 1099 Patients with negative LBC and positive hrHPV results were identified. Eight hundred sixty-nine had repeat Pap or histopathologic follow-up results. Average age was 41.2 years. Average follow-up was 23.2 months. Two hundred ninety of 869 had colposcopic examination and biopsies, including 33 diagnostic excisional procedures and 10 hysterectomies. Cervical intraepithelial neoplasia (CIN) 1 and low-grade squamous intraepithelial lesions (CIN1/LSIL) and more severe lesions (CIN1/LSIL+) were detected in 211 of 689 (24.3%). CIN2+ was diagnosed in 21 (2.4%) (1 VAIN3, 2 adenocarcinoma in situ, 1 invasive cervical adenocarcinoma). Six hundred six had repeat HPV tests and 200 had multiple repeat HPV tests. More LSIL/CIN1+ was identified with repeat positive HPV results than with repeat negative HPV results (P<0.001). LSIL/CIN1+ was detected more often with a history of LSIL/CIN1+ than with a history of negative Paps (P<0.001). Eight of 105 (7.6%) cytology-negative HPV-positive patients tested positive for HPV 16 and/or HPV 18., Conclusion: This is the largest study documenting follow-up on US cytology-negative hrHPV-positive patients screened with now widely utilized FDA-cleared methods of ciLBC and hrHPV testing. Of 869 patients followed for an average of almost 2 years, 20 cases of high grade intraepithelial neoplasia (2.3%) and one case of endocervical adenocarcinoma were detected. 90.5%(190/210) of intraepithelial neoplasias detected during follow-up were CIN1., (Copyright © 2011 Elsevier Inc.

- Abstract
Objective: To determine the incidence of clinically significant lesions on subsequent histologic follow-up in high-risk, predominantly minority patients with atypical glandular cells (AGC)., Study Design: A retrospective study was done on conventional Pap smears diagnosed as AGC of endocervical origin (AGC-EC), AGC of endometrial origin (AGC-EM) and AGC not otherwise specified (AGC-NOS) between January 1, 2003, and December 31, 2005. Histologic diagnoses were correlated with cytologic diagnoses., Result: Confirmed AGC cases were divided into 4 categories: 187 AGC-NOS, 169 AGC-EC, 68 AGC and atypical squamous cells of undetermined significance (ASCUS) and 36 AGC-EM. A total of 105 patients (22.8%) had significant precancerous (cervical intraepithelial neoplasia [CIN] 2/3, adenocarcinoma in situ [AIS]) or malignant (carcinoma) histologic outcomes. CIN 2/3 was the most common significant histologic outcome in women with AGC and ASCUS and patients <35 years with AGC. Endometrial neoplasia was the most common significant outcome in women with AGC-NOS and AGC-EM Pap results and in AGC patients > or =35. In women with AGC-EC Pap results, glandular cervical neoplasia occurred in 8.3% and CIN 2/3 in 5.9% offollow-up biopsies., Conclusion: AGC subtype and age significantly affect the probability of precancerous and malignant follow-up findings and anatomic site of neoplastic lesions. Access to newer screening technologies such as high-risk HPVDNA testing and liquid-based cytology will likely benefit such high-risk populations.

- Abstract
Issues: Increasing litigation over alleged false negative cervical cytologic (CC) smears threatens the viability of this test for cervical cancer detection. The problem appears to be largely American but is beginning to appear in some other countries. In the vast majority of cases there is either a settlement or jury verdict for the plaintiff based largely on the testimony of expert witnesses. Cases are judged on an individual basis without significant consideration of the general performance of the CC smear in laboratories operating in compliance with a wide array of laboratory regulations and with documented and comprehensive quality control practices in place. It is acknowledged that there are problem laboratories and cytology practitioners. There is an emerging issue of automated preparation and screening devices and issues of informed patient consent., Consensus Position: Cytology professionals have done an extraordinary and commendable job of educating the public about the benefits of the CC smear. We have been less successful and conscientious about explaining and defining the limitations of the CC test. There is a need for public and professional education as to the benefits and limitations of the CC smear for cervical cancer detection. The process suggested is to work with women's groups, public health agencies, government agencies, and state and national legislatures and to coordinate professional committees working on liability issues. Contextual information could be included with the CC smear report to indicate that a negative report confers a low probability of developing cervical cancer. It is suggested that appropriate language and a menu of statements be developed. Increased efforts should be directed to physician education with respect to informed consent concerning the benefits and limitations of CC smear testing and the application of new technology to improve smear accuracy. The process should include development of appropriate statements on the use of alternative technology. The profession should develop "process guidelines" for review of CC smears in the context of possible litigation, including standardized methods for blind slide review of smears that reduce or eliminate context and outcome bias. It is suggested that review panels be anonymous, that the process be standardized and that there be limitations on liability for participating organizations. Professional cytopathology and pathology societies should formulate acceptable guidelines for expert witnesses. The standards should be applicable to both defendant and plaintiff experts. All materials to the extent practical, including consultant opinions, should be available for peer review. Professional cytopathology and pathology societies should monitor expert testimony for objectivity and scientific accuracy., Ongoing Issues: For the near future, litigation will continue to focus on false negative CC smears on a case-by-case basis. Laboratories and individuals can reduce the risk of malpractice liability by directing their attention to proactive quality control and quality assurance methods. In the final analysis, consumer education about the benefits and limitations of the test is key to limiting malpractice claims. To stem the tide of continued medicolegal challenges to the integrity of cytology practice, the cytology community has now focused its efforts on developing and utilizing standards that convey to patients, attorneys and cytologists the contemporary status of and reasonable expectations for the practice of cytology. Guidelines such as those for uniform reporting terminology and clinical management of cervical abnormalities form the basis of cytology practice standards on which legal standards of practice can be based. Consensus conference reports, clinical management trials and scientifically valid studies of false negative rates that analyze the type, frequency and cause of missed cases represent sounder methods of establishing defensible
