Abstract Background Multicentric intraepithelial lesions of the lower genital tract (multicentric lesions) were defined as intraepithelial lesions of two or three sites within cervix, vagina, and vulva occurring synchronously or sequentially. The characteristics of multicentric lesions has been poorly understood. This study aimed to evaluate the risk factors for multicentric lesions, including specific HPV genotypes. Methods A retrospective case-control study was performed involving patients histologically diagnosed with multicentric lesions between January 2018 and October 2019. Controls were patients histologically diagnosed with single cervical intraepithelial neoplasia (CIN) and admitted during the same period. Univariable and multivariable analyses were used to assess the risk factors for multicentric lesions. Results Of 307 patients with multicentric lesions, the median age was 50 years (interquartile range: 43–55.5), and they were older than patients with single CIN (median age: 43 years, interquartile range: 36–50). In the multicentric lesion group, the proportions of cytologic abnormalities, HPV positivity, and multiple HPV infections were 68.9, 97.0, and 36.5%, respectively. In the multivariable analysis, menopause, a history of malignant tumors beyond the lower genital tract and multiple HPV infections were associated with the incidence of multicentric lesions (Odd ratio (OR) = 3.14, 95% confidence interval (CI) 2.24–4.41; OR = 9.58, 95% CI 1.02–89.84; OR = 1.47, 95% CI 1.03–2.10). The common HPV genotypes were HPV16, HPV53, HPV58, HPV52, HPV51, HPV56 and HPV18 in patients with multicentric lesions. The proportion of HPV16 infection was higher in high-grade lesions group than that in low-grade lesions group (OR = 2.54, 95% CI 1.34–4.83). The OR for multicentric lesions, adjusted for menopause, smoking, gravidity, parity, a history of malignant tumor beyond the lower genital tract and multiple HPV infection, was 1.97 (95% CI 1.04–3.75) in patients with HPV51 infection. Conclusions Multicentric lesions were associated with menopause, a history of malignant tumors and multiple HPV infections. HPV16 was the most common genotype, especially in high grade multicentric lesions and HPV51 infection was found to be a risk factor for detecting multicentric lesions.

Objective To compare the prevalence of abnormal anal cytology and high-risk HPV among women with a recent history of HPV-related genital neoplasia to women without a history of HPV-related genital neoplasia. Methods: A cross-sectional pilot study was performed. Women with a history of high-grade cervical, vulvar, or vaginal dysplasia or cancer within the past 2 years were eligible for the exposed group. Women without a history of high-grade anogenital dysplasia or cancer were eligible for the control group. Anal cytology and HPV genotyping were performed after informed consent was obtained. Results: 127 women were enrolled in the exposed group and 45 in the control group. The control group was slightly older and less likely to be current smokers. There was no difference between groups in history of anal intercourse. Forty-four per cent of the exposed group had abnormal anal cytology compared with 21.6% of the control group (P = 0.03). High-risk HPV was detected in the anal canal of 6 in the exposed group compared with none in the control group (P = 0.2). Fourteen per cent of the anal cytology results were read as insufficient in both groups. HPV results were insufficient in 29.2% of exposed versus 43.5% of control (P = 0.2). Conclusions: Women with a history of lower genital tract dysplasia are more likely to have a positive anal cytology result compared with women without a history. Additional information is needed to determine the best method of anal cancer screening among women with a history of lower genital tract dysplasia.

Purpose. This study investigated the infection status and relationship between other common lower genital tract infectious pathogens and high-risk human papillomavirus (HR-HPV) in the high-grade cervical lesions. Methods. Overall, 882 patients were enrolled in this retrospective study, of which 339 patients (≥HSIL group) were confirmed with high-grade squamous intraepithelial lesions (HSIL) or cervical squamous cell carcinoma (SCC), while 543 patients (≤LSIL group) were diagnosed with low-grade squamous intraepithelial lesions (LSIL) or normal cervical pathology diagnosis. Cervical swab specimens were tested for HPV, pathogenic bacteria (PB), U. urealyticum (UU), M. hominis (MH), and C. trachomatis (CT) in both groups. Results. The infection rates of HR-HPV, PB, UU (at high density), and CT were higher in the ≥HSIL group than in the ≤LSIL group (P<0.001); however, higher infection rates with MH were not observed (P>0.05). PB, UU, and CT were associated with HR-HPV infection (P<0.001). The PB and UU infection rates in the ≥HSIL group were significantly different from those in the ≤LSIL group, regardless of whether there was an HR-HPV infection at the same time (P<0.05). However, this was not the case for the CT (P>0.05). Furthermore, 259 pathogenic bacterial strains were detected in 882 cases. The difference in the distribution of pathogenic bacterial flora in the different grades of cervical lesions had no statistical significance, which was prioritized over Escherichia coli (P>0.05). Conclusion. PB, UU, and CT infection is associated with susceptibility to HR-HPV, HR-HPV coinfection with these pathogens might increase the risk of high-grade cervical lesions, and PB and UU might be independent risk factors for cervical lesions.

Abstract Background Women living with human immunodeficiency virus (WLHIV) have disproportionately high rates of squamous cell carcinoma of the anus compared with the general population of women. Anal high-grade squamous intraepithelial lesions (HSILs) precede anal cancer, and accurate studies of HSIL prevalence among WLHIV in the United States are lacking. Methods The AIDS Malignancy Consortium 084 study was a multicenter national trial to evaluate the prevalence of and risk factors for anal HSIL in a US cohort. Eligible participants were WLHIV aged ≥18 years with no history of anal HSIL. Study participants had an examination including collection of cervical/vaginal and anal specimens, followed by high-resolution anoscopy with biopsy. Results We enrolled 256 women with evaluable anal pathology. The mean age was 49.4 years, 64% women were non-Hispanic black, 67% were former or current smokers, and 56% reported ever having anal sex with a man. The median CD4 T-cell count was 664 cells/μL. The prevalence of anal histologic HSIL (hHSIL) was 27% (95% confidence interval [CI], 22%–33%). There was a strong concordance (240/254) between local and consensus pathologists for hHSIL vs less than hHSIL (κ = 0.86 [95% CI, .79–.93]). Current CD4 count of ≤200 cells/μL was the strongest predictor of consensus anal hHSIL diagnosis (adjusted odds ratio [aOR], 10.34 [95% CI, 3.47–30.87]). History of anoreceptive intercourse was also associated with hHSIL (aOR, 2.44 [95% CI, 1.22–4.76]). Conclusions The prevalence of anal hHSIL in WLHIV in the United States was 27% in this study where all participants received high-resolution anoscopy and biopsy.

Objective A vulvar squamous intraepithelial lesion is deemed to be a preceding lesion to vulvar cancer, especially in women aged under 40 years, holders of an acquired or idiopathic immunosuppression. Several treatments have been used to treat these lesions. One of the aesthetically acceptable therapeutic methods is the CO2 laser vaporization. Methods In a transversal study, 46 records of immunosuppressed women bearing a vulvar low grade and/or high grade squamous intraepithelial lesion were selected out of the retrospective analysis, computing age, date of record, date of vulvar lesion treatment with CO2 laser, the time elapsed between the first and the last visit (in months), the number of visits, the presence or absence of condylomatous lesions in other female lower genital tract sites and whether or not recurrences and persistence of intraepithelial lesions have been noticed during the follow-up. Results Patients bearing vulvar high-grade squamous intraepithelial lesion and immunosuppressed (serum positive for human immunodeficiency virus [HIV] or with solid organs transplantation) have shown a higher level of persistence of lesions and a higher chance of having other areas of the female lower genital tract involved. Conclusion While the CO2 laser vaporization is the most conservative method for the treatment of vulvar high-grade intraepithelial lesions, it is far from being the ideal method, due to the intrinsic infection features considered. The possibility of persistence, recurrences and spontaneous limited regression indicates that a closer surveillance in the long-term treated cases should be considered, in special for immunosuppressed patients.

Abstract Background Online clinical risk prediction tools built on data from multiple cohorts are increasingly being utilized for contemporary doctor-patient decision-making and validation. This report outlines a comprehensive data science strategy for building such tools with application to the Prostate Biopsy Collaborative Group prostate cancer risk prediction tool. Methods We created models for high-grade prostate cancer risk using six established risk factors. The data comprised 8492 prostate biopsies collected from ten institutions, 2 in Europe and 8 across North America. We calculated area under the receiver operating characteristic curve (AUC) for discrimination, the Hosmer-Lemeshow test statistic (HLS) for calibration and the clinical net benefit at risk threshold 15%. We implemented several internal cross-validation schemes to assess the influence of modeling method and individual cohort on validation performance. Results High-grade disease prevalence ranged from 18% in Zurich (1863 biopsies) to 39% in UT Health San Antonio (899 biopsies). Visualization revealed outliers in terms of risk factors, including San Juan VA (51% abnormal digital rectal exam), Durham VA (63% African American), and Zurich (2.8% family history). Exclusion of any cohort did not significantly affect the AUC or HLS, nor did the choice of prediction model (pooled, random-effects, meta-analysis). Excluding the lowest-prevalence Zurich cohort from training sets did not statistically significantly change the validation metrics for any of the individual cohorts, except for Sunnybrook, where the effect on the AUC was minimal. Therefore the final multivariable logistic model was built by pooling the data from all cohorts using logistic regression. Higher prostate-specific antigen and age, abnormal digital rectal exam, African ancestry and a family history of prostate cancer increased risk of high-grade prostate cancer, while a history of a prior negative prostate biopsy decreased risk (all p-values < 0.004). Conclusions We have outlined a multi-cohort model-building internal validation strategy for developing globally accessible and scalable risk prediction tools.

Aims: To compare commonly mentioned risk factors between mild germinal matrix hemorrhage-Intraventricular hemorrhage (GMH-IVH) (grade I & II) and severe GMH-IVH (grade III & IV) and to study the long-term neurodevelopmental outcomes in relation to severe GMH-IVH. Study Design: Retrospective cohort study. Place and Duration of Study: Neonatal intensive care unit, King Fahad University Hospital, between 2000 and 2020. Methodology: We included 54 premature infants at ≤36 weeks of gestation and with birth weight <2500g admitted to our neonatal intensive care unit. Premature neonates were divided into two subgroups: mild GMH-IVH (grade I and II) and severe (grade III and IV). We investigated the risk factors and neurodevelopmental outcomes in association with GMH-IVH. Results: Amnionitis (OR: 1.190, 95% CI 0.515-2.749), lower genital tract infection (OR: 1.190, 95% CI 0.515-2.749), antenatal infection (OR: 1.406, 95% CI 0.866-2.283), gestational diabetes mellitus (OR: 1.815, 95% CI 1.410-2.337), usage of inotropes (OR: 1.731, 95% CI 1.348-2.222), APGAR score <7 (OR: 0.806, 95% CI 0.493-1.316), birth trauma (OR: 1.767, 95% CI 1.396-2.236), catecholamines (OR: 1.470, 95% CI 0.903-2.393), intubation (OR: 1.300, 95% CI 0.686-2.464), asphyxia (OR: 1.135, 95% CI 0.718-1.794), Abnormal coagulation (OR: 1.197, 95% CI 0.756-1.896), congenital heart disease (OR: 1.727, 95% CI 1.124-2.653), low hematocrit (OR: 1.140, 95% CI 0.688-1.889), resuscitation (OR: 1,193, 95% CI 0.748- 1.904) and ventriculoperitoneal (VP) shunt as a prognosis of hydrocephalus (P-value: 0.005) all showed a higher incidence with severe GMH-IVH Conclusion: Amnionitis, lower genital tract infection, antenatal infections, GDM, usage of inotropes, APGAR score <7, birth trauma, catecholamines, intubation, asphyxia, resuscitation, abnormal coagulation parameters, congenital heart disease, low hematocrit and hydrocephalus with VP shunt were higher in severe GMH-IVH.
