Regional variation in histopathology‐specific incidence of invasive cervical cancer among Peruvian women

ObjectiveTo evaluate patterns of cervical cancer incidence in Peru by examining variation in 2 common histopathologic types, squamous cell carcinoma (SCC) and adenocarcinoma (ADC), and analyzing trends over time.MethodsData on the incidence of invasive cervical cancer between 1984 and 2006 were obtained from 3 population‐based cancer registries in Peru: Lima, Trujillo, and Arequipa. For each registry, data quality assessment was performed, crude and age‐specific incidence was calculated, and time trends were analyzed.ResultsOverall and SCC incidence varied across registries but incidence of ADC did not. Overall and SCC incidence showed significant declines in Trujillo (P 0.05) over time. ADC incidence showed marginally significant increases among women aged 15–29 years in Trujillo (P = 0.10) and modest increases among young women in Lima (P > 0.05).ConclusionPopulation‐based cancer registries were an efficient source of data for evaluating the incidence of cervical cancer once data quality had been established. Geographic and temporal variations in cervical cancer burden were documented in Peru. The trends suggest that cervical ADC is increasing among young women in urban Peru, particularly in Trujillo. We recommend supplementing current Papanicolaou test screening with complementary methods of cervical cancer control, including human papillomavirus (HPV) vaccination and HPV DNA testing.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/135622/1/ijgo47.pd

Effect of angiotensin-converting enzyme inhibitor and angiotensin receptor blocker initiation on organ support-free days in patients hospitalized with COVID-19

IMPORTANCE Overactivation of the renin-angiotensin system (RAS) may contribute to poor clinical outcomes in patients with COVID-19. Objective To determine whether angiotensin-converting enzyme (ACE) inhibitor or angiotensin receptor blocker (ARB) initiation improves outcomes in patients hospitalized for COVID-19. DESIGN, SETTING, AND PARTICIPANTS In an ongoing, adaptive platform randomized clinical trial, 721 critically ill and 58 non–critically ill hospitalized adults were randomized to receive an RAS inhibitor or control between March 16, 2021, and February 25, 2022, at 69 sites in 7 countries (final follow-up on June 1, 2022). INTERVENTIONS Patients were randomized to receive open-label initiation of an ACE inhibitor (n = 257), ARB (n = 248), ARB in combination with DMX-200 (a chemokine receptor-2 inhibitor; n = 10), or no RAS inhibitor (control; n = 264) for up to 10 days. MAIN OUTCOMES AND MEASURES The primary outcome was organ support–free days, a composite of hospital survival and days alive without cardiovascular or respiratory organ support through 21 days. The primary analysis was a bayesian cumulative logistic model. Odds ratios (ORs) greater than 1 represent improved outcomes. RESULTS On February 25, 2022, enrollment was discontinued due to safety concerns. Among 679 critically ill patients with available primary outcome data, the median age was 56 years and 239 participants (35.2%) were women. Median (IQR) organ support–free days among critically ill patients was 10 (–1 to 16) in the ACE inhibitor group (n = 231), 8 (–1 to 17) in the ARB group (n = 217), and 12 (0 to 17) in the control group (n = 231) (median adjusted odds ratios of 0.77 [95% bayesian credible interval, 0.58-1.06] for improvement for ACE inhibitor and 0.76 [95% credible interval, 0.56-1.05] for ARB compared with control). The posterior probabilities that ACE inhibitors and ARBs worsened organ support–free days compared with control were 94.9% and 95.4%, respectively. Hospital survival occurred in 166 of 231 critically ill participants (71.9%) in the ACE inhibitor group, 152 of 217 (70.0%) in the ARB group, and 182 of 231 (78.8%) in the control group (posterior probabilities that ACE inhibitor and ARB worsened hospital survival compared with control were 95.3% and 98.1%, respectively). CONCLUSIONS AND RELEVANCE In this trial, among critically ill adults with COVID-19, initiation of an ACE inhibitor or ARB did not improve, and likely worsened, clinical outcomes.

Variation of cervical cancer incidence in Latin America and the Caribbean Variación de la incidencia del cáncer cervicouterino en América Latina y el Caribe

OBJECTIVE: To provide a comprehensive analysis of the descriptive epidemiology of invasive cervical cancer in Latin America and the Caribbean by analyzing quality data from the area's cancer registries, including data that were excluded from the International Agency for Research on Cancer (IARC) publication, Cancer Incidence in Five Continents, Vol. IX (CI5-IX). METHODS: This was a descriptive epidemiologic study that involved 20 cancer registries, 9 of which were included by IARC in CI5-IX, and 11 of which were not. Data on invasive cervical cancers diagnosed from 1998-2002 were obtained from IARC. A cervical cancerspecific quality assessment was performed on all registries whether or not they were included in CI5-IX. Data from 14 registries met quality criteria and were analyzed. Incidence rates were calculated and compared across registries. RESULTS: A substantial variation in incidence rates existed among the registries; agestandardized rates ranged from 14.6-44.0 per 100 000 women per year. Mean cervical cancer incidence rates were 10.4% higher for registries included in CI5-IX than for those excluded; however, this difference was not significant (P = 0.541). CONCLUSIONS: This study compared cervical cancer rates from a more diverse group of Latin American and Caribbean countries than that of the CI5-IX. The heterogeneity found among registries highlights the importance of examining data from as many registries as possible when characterizing risk across a geographic area. Data from developing countries can be used to better understand cancer distribution and enable Region-specific recommendations on cancer control and prevention once data quality has been establishedOBJETIVO: Efectuar un análisis integral de las características epidemiológicas descriptivas del cáncer de cervicouterino invasor en América Latina y el Caribe mediante el análisis de datos de calidad de los registros de cáncer de la región, incluso datos que fueron excluidos de la publicación del Centro Internacional de Investigaciones sobre el Cáncer (CIIC), Incidencia del cáncer en cinco continentes, Vol. IX (CI5-IX). MÉTODOS: En este estudio epidemiológico descriptivo se incluyeron 20 registros sobre el cáncer, de los cuales solo nueve fueron incluidos por el CIIC en el informe CI5-IX. Los datos sobre cáncer cervicouterino invasor diagnosticado entre 1998 y 2002 se obtuvieron a partir del CIIC. Se llevó a cabo una evaluación de la calidad de todos los registros específica para el cáncer cervicouterino, con independencia de que estuvieran incluidos en el informe CI5-IX o no. Los datos de 14 registros satisficieron los criterios de calidad y se analizaron. Se calcularon las tasas de incidencia y se compararon estas entre los registros. RESULTADOS: Entre los registros se comprobó una variación sustancial en las tasas de incidencia; las tasas normalizadas según la edad variaron entre 14,6 y 44,0 por 100 000 mujeres por año. Las tasas de incidencia medias de cáncer cervicouterino fueron 10,4% mayores en los registros incluidos en el CI5-IX que en aquellos excluidos; sin embargo, esta diferencia no fue significativa (P = 0,541). CONCLUSIONES: En este estudio se compararon las tasas de cáncer cervicouterino de un grupo más diverso de países de América Latina y el Caribe que el comprendido en el informe CI5-IX. La heterogeneidad encontrada entre los registros destaca la importancia de examinar los datos de tantos registros como sea posible cuando se caracteriza el riesgo en una zona geográfica. Los datos de los países en desarrollo pueden usarse para conocer más a fondo la distribución del cáncer y permiten formular recomendaciones específicas para la región sobre el control y la prevención del cáncer, una vez que se ha comprobado la calidad de los datos

HPV16 E6 seropositivity among cancer-free men with oral, anal or genital HPV16 infection

Antibodies against the Human papillomavirus 16 (HPV16) E6 oncoprotein appear years prior to clinical diagnosis of anal and oropharyngeal cancer, but whether they develop around the time of HPV infection is unclear. Serum samples from 173 cancer-free men from the Human Papillomavirus Infection in Men (HIM) Study were tested for HPV antibodies and DNA. HPV16 E6 seropositivity was low among men with oral HPV16-infection (1/28; 3.6%, 95%CI=0.0–18.4%), anal HPV16-infection (1/61; 1.6%, 95%CI=0.0–8.8%), and 24-month persistent genital HPV16-infection (1/84; 1.2%, 0.0–6.5%). This suggests E6 seroconversion may not occur around the time of oral, anal, or genital HPV16 acquisition. Keywords: HPV, HPV16 E6 seropositivity, Oropharyngeal cancer, Anal cancer, Penile cance

Seroprevalence of Cutaneous Human Papillomaviruses and the Risk of External Genital Lesions in Men: A Nested Case-Control Study.

A variety of cutaneous human papillomaviruses (HPV) are detectable in genital epithelial lesions in men and non-melanoma skin cancer patients. It remains unclear whether these viruses are associated causally with skin lesions. To date, no study has prospectively examined the association between cutaneous HPV seropositivity and development of external genital lesions (EGLs) in men.To examine the association between seropositivity to cutaneous HPV types and the risk of subsequent development of EGLs.A nested case-control study including 163 incident EGL cases and 352 EGL-free controls in the HPV Infection in Men (HIM) Study cohort was conducted. Cases were ascertained at each of up to 10 biannual clinical visits and verified through biopsy and pathological diagnoses. EGLs were categorized as condyloma, suggestive of condyloma, penile intraepithelial neoplasia (PeIN), and other EGLs. Archived serum specimens collected at baseline were tested for antibodies against 14 cutaneous HPV types (β types (5, 8, 12, 14, 17, 22, 23, 24, 38, and 47), α type 27, γ type 4, μ type 1, and ν type 41) using a GST L1-based multiplex serology assay. Socio-demographic and sexual behavior data were collected through a questionnaire. Using logistic regression, adjusted odds ratios (AOR) and 95% confidence intervals (CI) were estimated.Overall, seropositivity to ≥1 cutaneous HPV type (any-HPV) and ≥1 β types (any-β) was 58.3% and 37.5% among other EGL cases, 71.6% and 46.8% among condyloma, 66.8% and 50.0% among PeIN, and 71.9% and 38.4% among controls, respectively. Type-specific seropositivity was most common for ɤ-HPV 4, μ-HPV 1, and β-HPV 8. No statistically significant association was observed between any-HPV, any-β, and type-specific HPV seropositivity and subsequent development of EGLs across all pathological diagnoses.Overall, seropositivity to cutaneous HPV was common among men; however, it appears that cutaneous HPV is not associated with the development of genital lesions in men

Seroprevalence and Associated Factors of 9-Valent Human Papillomavirus (HPV) Types among Men in the Multinational HIM Study.

Human papillomavirus (HPV) is one of the most common sexually transmitted infections worldwide. Recently a 9-valent HPV (9vHPV) prophylactic vaccine was licensed. Seroprevalence prior to vaccine dissemination is needed for monitoring vaccine effectiveness over time. Few studies have assessed the seroprevalence of 9vHPV types in men.To investigate the seroprevalence of 9vHPV vaccine types and associated risk factors among men residing in Brazil, Mexico, and the United States.Six hundred men were randomly selected from the HPV Infection in Men (HIM) Study. Archived serum specimens collected at enrollment were tested for antibodies against nine HPV types (6, 11, 16, 18, 31, 33, 45, 52 and 58) using a glutathione S-transferase (GST) L1-based multiplex serologic assay. Socio-demographic, lifestyle and sexual behavior data at enrollment were collected through a questionnaire. Binomial proportions were used to estimate seroprevalence and logistic regression was used to examine factors associated with seropositivity of type-specific and grouped (i.e. 9vHPV, high-risk 9vHPV, low risk 9vHPV, and five-additional) HPV types.Overall, 28.3% of men were seropositive for at least one of the 9vHPV vaccine types, 14.0% for at least one of the seven high-risk types (16, 18, 31, 33, 45, 52 and 58) and 11.2% for at least one of the five high-risk types (31, 33, 45, 52 and 58) not included in the quadrivalent HPV vaccine, and 17.4% for at least one of the low-risk types (6/11). In multivariate analyses, odds ratios adjusted (AOR) for country of residence, age, marital status, smoking, number of anal sex lifetime partners, compared to men with no anal sex lifetime partners, men with ≥2 partners were more likely to be seropositive for grouped HPV [(9vHPV: AOR 2.52; 95% confidence interval (CI) 1.40-4.54), (high-risk 9vHPV: AOR 2.18; 95%CI: 1.05-4.50) and (low-risk 9vHPV: AOR 2.12; 95%CI: 1.12-4.03)], and individual HPV types 6, 16, 33 and 58 with AORs ranging from 2.19 to 7.36. Compared to men aged 18-30 years, men older than 30 years were significantly more likely to be seropositive for any high-risk 9vHPV, in addition to individual types 18 and 45; and compared to never smokers, current smokers were more likely to be seropositive to 9vHPV, low-risk 9vHPV and HPV 6. In contrast, married men were less likely to be seropositive to any high-risk 9vHPV and individual HPV types 18 and 31 when compared to single men.These data indicate that exposure to the nine HPV types included in the 9vHPV vaccine is common in men and that seropositivity to 9vHPV vaccine types is associated with older age and the lifetime number of anal sex partners. Nine valent HPV vaccination of males and females has the potential to prevent HPV related diseases and transmission in both sexes
