Evaluation of mortality among Marines, Navy personnel, and civilian workers exposed to contaminated drinking water at USMC base Camp Lejeune: a cohort study.

BACKGROUND: Drinking water at U.S. Marine Corps Base (MCB) Camp Lejeune, North Carolina was contaminated with trichloroethylene and other industrial solvents from 1953 to 1985. METHODS: A cohort mortality study was conducted of Marines/Navy personnel who, between 1975 and 1985, began service and were stationed at Camp Lejeune (N = 159,128) or MCB Camp Pendleton, California (N = 168,406), and civilian workers employed at Camp Lejeune (N = 7,332) or Camp Pendleton (N = 6,677) between October 1972 and December 1985. Camp Pendleton's drinking water was not contaminated with industrial solvents. Mortality follow-up was between 1979 and 2018. Proportional hazards regression was used to calculate adjusted hazard ratios (aHRs) comparing mortality rates between Camp Lejeune and Camp Pendleton cohorts. The ratio of upper and lower 95% confidence interval (CI) limits, or CIR, was used to evaluate the precision of aHRs. The study focused on underlying causes of death with aHRs ≥ 1.20 and CIRs ≤ 3. RESULTS: Deaths among Camp Lejeune and Camp Pendleton Marines/Navy personnel totaled 19,250 and 21,134, respectively. Deaths among Camp Lejeune and Camp Pendleton civilian workers totaled 3,055 and 3,280, respectively. Compared to Camp Pendleton Marines/Navy personnel, Camp Lejeune had aHRs ≥ 1.20 with CIRs ≤ 3 for cancers of the kidney (aHR = 1.21, 95% CI: 0.95, 1.54), esophagus (aHR = 1.24, 95% CI: 1.00, 1.54) and female breast (aHR = 1.20, 95% CI: 0.73, 1.98). Causes of death with aHRs ≥ 1.20 and CIR > 3, included Parkinson disease, myelodysplastic syndrome and cancers of the testes, cervix and ovary. Compared to Camp Pendleton civilian workers, Camp Lejeune had aHRs ≥ 1.20 with CIRs ≤ 3 for chronic kidney disease (aHR = 1.88, 95% CI: 1.13, 3.11) and Parkinson disease (aHR = 1.21, 95% CI: 0.72, 2.04). Female breast cancer had an aHR of 1.19 (95% CI: 0.76, 1.88), and aHRs ≥ 1.20 with CIRs > 3 were observed for kidney and pharyngeal cancers, melanoma, Hodgkin lymphoma, and chronic myeloid leukemia. Quantitative bias analyses indicated that confounding due to smoking and alcohol consumption would not appreciably impact the findings. CONCLUSION: Marines/Navy personnel and civilian workers likely exposed to contaminated drinking water at Camp Lejeune had increased hazard ratios for several causes of death compared to Camp Pendleton.

Prevalence of human papillomavirus genotypes in high-grade cervical precancer and invasive cervical cancer from cancer registries before and after vaccine introduction in the United States.

BACKGROUND: US population-based cancer registries can be used for surveillance of human papillomavirus (HPV) types found in HPV-associated cancers. Using this framework, HPV prevalence among high-grade cervical precancers and invasive cervical cancers were compared before and after HPV vaccine availability. METHODS: Archived tissue from 2 studies of cervical precancers and invasive cervical cancers diagnosed from 1993-2005 (prevaccine) were identified from 7 central cancer registries in Florida; Hawaii; Iowa; Kentucky; Louisiana; Los Angeles County, California; and Michigan; from 2014 through 2015 (postvaccine) cases were identified from 3 registries in Iowa, Kentucky, and Louisiana. HPV testing was performed using L1 consensus polymerase chain reaction analysis. HPV-type-specific prevalence was examined grouped by hierarchical attribution to vaccine types: HPV 16, 18, HPV 31, 33, 45, 52, 58, other oncogenic HPV types, and other types/HPV negative. Generalized logit models were used to compare HPV prevalence in the prevaccine study to the postvaccine study by patient age, adjusting for sampling factors. RESULTS: A total of 676 precancers (328 prevaccine and 348 postvaccine) and 1140 invasive cervical cancers (777 prevaccine and 363 postvaccine) were typed. No differences were observed in HPV-type prevalence by patient age between the 2 studies among precancers or invasive cancers. CONCLUSIONS: The lack of reduction in vaccine-type prevalence between the 2 studies is likely explained by the low number of cases and low HPV vaccination coverage among women in the postvaccine study. Monitoring HPV-type prevalence through population-based strategies will continue to be important in evaluating the impact of the HPV vaccine.

Racial and ethnic differences in human papillomavirus positivity and risk factors among low-income women in Federally Qualified Health Centers in the United States.

Reasons for racial/ethnic disparities in HPV infection are unclear. This study assessed racial/ethnic differences in and risk factors for HPV positivity among low-income women. Data were collected from 984 low-income women visiting Federally Qualified Health Centers across Illinois (2009-2011). Pearson chi square and Logistic regression analyses were used to examine associations with HPV positivity. Our results showed Mexican-born Hispanics had the lowest HPV positivity (16%), followed by non-Hispanic whites (29%), US-born Hispanics (35%), and non-Hispanic blacks (39%). Mexican-born Hispanics reported fewer risk behaviors for HPV positivity, including first sexual intercourse before age 16 years (9% versus 27%), multiple sexual partners in lifetime (48% versus 90%), and current cigarette smoking status (10% versus 35%) when compared to non-Hispanic whites (p<0.001). In multivariate-adjusted logistic regression, being non-Hispanic black, first sexual intercourse before age 16 years, increasing numbers of recent or lifetime sexual partners and current cigarette smoking status were associated with a higher likelihood of HPV positivity. Our findings highlight racial/ethnic differences in HPV positivity and risk factors in a population of women with similar socioeconomic characteristics. When measuring HPV risk factors within the Hispanic population, foreign-born status and other mediating factors, such as social norms and cultural characteristics, may be relevant to assess the intragroup heterogeneity.

Type-specific HPV and Pap test results among low-income, underserved women: providing insights into management strategies.

OBJECTIVE: The primary cervical cancer screening strategy for women over age 30 is high-risk human papillomavirus (HPV) testing combined with Papanicolaou (Pap) testing (cotesting) every 5 years. This combination strategy is a preventive service that is required by the Affordable Care Act to be covered with no cost-sharing by most health insurance plans. The cotesting recommendation was made based entirely on prospective data from an insured population that may have a lower proportion of women with HPV positive and Pap negative results (ie, discordant results). The discordant group represents a very difficult group to manage. If the frequency of discordant results among underserved women is higher, health care providers may perceive the cotesting strategy to be a less favorable screening strategy than traditional Pap testing every 3 years. STUDY DESIGN: The Centers for Disease Control and Prevention's Cervical Cancer Study was conducted at 15 clinics in 6 federally qualified health centers across Illinois. Providers at these clinics were given the option of cotesting for routine cervical cancer screening. Type-specific HPV detection was performed on residual extracts using linear array. RESULTS: Pap test results were abnormal in 6.0% and HPV was positive in 7.2% of the underserved women screened in this study (mean age, 45.1 years). HPV prevalence decreased with age, from 10.3% among 30- to 39-year-olds to 4.5% among 50- to 60-year-olds. About 5% of the women had a combination of a positive HPV test and normal Pap test results; HPV 16/18 was identified in 14% of discordant women. CONCLUSION: The rate of discordant results among underserved women was similar to those reported throughout the US in a variety of populations. Typing for HPV 16/18 appears to assist in the management in a small proportion of women with discordant results.

Cancer Incidence among Marines and Navy Personnel and Civilian Workers Exposed to Industrial Solvents in Drinking Water at US Marine Corps Base Camp Lejeune: A Cohort Study.

BACKGROUND: Drinking water at US Marine Corps Base Camp Lejeune, North Carolina, was contaminated with trichloroethylene and other industrial solvents from 1953 to 1985. METHODS: A cohort cancer incidence study was conducted of Marines/Navy personnel who began service and were stationed at Camp Lejeune (N=154,821) or Camp Pendleton, California (N=163,484) between 1975 and 1985 and civilian workers employed at Camp Lejeune (N=6,494) or Camp Pendleton (N=5,797) between October 1972 and December 1985. Camp Pendleton's drinking water was not contaminated with industrial solvents. Individual-level information on primary invasive cancers and in situ bladder cancer diagnosed between 1996 and 2017 was obtained from 54 US cancer registries. Proportional hazards regression was used to calculate adjusted hazard ratios (aHRs) comparing cancer incidence between the Camp Lejeune and Camp Pendleton cohorts, adjusted for sex, race, education, and rank (or blue-collar work), with age as the time variable. Precision of aHRs was evaluated using the 95% confidence interval (CI) ratio (CIR). RESULTS: Cancers among Camp Lejeune Marines/Navy personnel and civilian workers totaled 12,083 and 1,563, respectively. Cancers among Camp Pendleton Marines/Navy personnel and civilian workers totaled 12,144 and 1,416, respectively. Compared with Camp Pendleton, Camp Lejeune Marines/Navy personnel had aHRs ≥1.20 with CIRs ≤3 for all myeloid cancers (HR=1.24; 95% CI: 1.03, 1.49), acute myeloid leukemia (HR=1.38; 95% CI: 1.03, 1.85), myelodysplastic and myeloproliferative syndromes (HR=1.68; 95% CI: 1.07, 2.62), polycythemia vera (HR=1.41; 95% CI: 0.94, 2.11), and cancers of the esophagus (HR=1.27; 95% CI: 1.03, 1.56), larynx (HR=1.21; 95% CI: 0.98, 1.50), soft tissue (HR=1.21; 95% CI: 0.92, 1.59), and thyroid (HR=1.22; 95% CI: 1.03, 1.45). Lymphoma subtypes mantle cell and marginal zone B-cell and lung cancer subtypes adenocarcinoma and non-small cell lung cancer also had aHRs ≥1.20 with CIRs ≤3. Compared with Camp Pendleton, Camp Lejeune civilian workers had aHRs ≥1.20 with CIRs ≤3 for all myeloid cancers (HR=1.40; 95% CI: 0.83, 2.36), squamous cell lung cancer (HR=1.63; 95% CI: 1.10, 2.41), and female breast (HR=1.21; 95% CI: 0.97, 1.52) and ductal cancer (HR=1.32; 95% CI: 1.02, 1.71). CONCLUSION: Increased risks of several cancers were observed among Marines/Navy personnel and civilian workers exposed to contaminated drinking water at Camp Lejeune compared with Camp Pendleton. https://doi.org/10.1289/EHP14966.

Scrotal Cancer Incidence Rates and Trends-United States, 1999-2020.

OBJECTIVE: To examine population-level scrotal cancer incidence rates and trends among adult men in the United States. METHODS: Data from the United States Cancer Statistics, covering approximately 96% of the United States population, were analyzed to calculate age-standardized incidence rates of scrotal cancer among men aged 18 years and older from 1999 to 2020. Trends in incidence rates were evaluated by age, race and ethnicity, Census region, and histology using joinpoint regression. RESULTS: Overall, 4669 men were diagnosed with scrotal cancer (0.20 per 100,000). Incidence rates were highest among men aged 70 years and older (0.82 per 100,000). Rates were higher among non-Hispanic Asian or Pacific Islander men (0.31 per 100,000) compared to other race and ethnicity groups. The most common histologic subtypes were squamous cell carcinoma (35.9%), extramammary Paget disease (20.8%), and sarcoma (20.5%). Incidence rates decreased by 2.9% per year from 1999 to 2019 for non-Hispanic Asian or Pacific Islander men, decreased by 8.1% per year from 1999 to 2006 for basal cell carcinomas, and increased by 1.8% per year from 1999 to 2019 for extramammary Paget disease; otherwise, rates remained stable for all other variables examined. CONCLUSION: While scrotal cancer incidence rates were higher than previously reported, rates were still low and stable over time.

Predicting 10-year alcohol use trajectories among men age 50 years and older.

OBJECTIVE: To describe common 10-year drinking trajectories followed by men age 50 years or older and identify risk factors for those trajectories. DESIGN: Longitudinal data were used to derive a semiparametric group-based model. PARTICIPANTS: Men from the Health and Retirement Study age 50-65 years in 1998 who completed three or more of the six interviews conducted from 1998 to 2008, including our 1998 baseline interview. MEASUREMENTS: Biannual data on number of drinks per drinking day were used to derive drinking trajectories. Risk factors included baseline age, race, ethnicity, education, marital status, retirement, smoking, binge drinking, vigorous exercise, body mass index, depression, pain, self-reported health, and chronic disease. RESULTS: The best-fitting model included consistent infrequent drinkers and nondrinkers (40.6% of cohort), increasing drinkers (5.5%), decreasing drinkers (7.6%), consistent at-risk drinkers (15.6%), and consistent moderate drinkers (30.7%). Adjusted logistic regression models comparing men with similar 1998 drinking levels who subsequently followed different trajectories identified significant risks associated with age, education, smoking, binge drinking, depression, pain, and self-reported health. To illustrate, odds ratios (ORs) and 95% confidence intervals (95% CIs) suggest that baseline infrequent drinkers were less likely to follow an increasing drinkers trajectory if they were older (OR: 0.57, 95% CI: 0.38-0.82) and smoked cigarettes (OR: 0.47, 95% CI: 0.30-0.74). Baseline drinkers were less likely to follow a decreasing trajectory if they reported more than 12 years of education (OR: 0.58, 95% CI: 0.42-0.82) and thought that their health was excellent or very good (OR: 0.54, 95% CI: 0.39-0.76). CONCLUSION: Only 30.7% of older men in this cohort were moderate drinkers throughout the follow-up. Many older men may benefit from brief counseling on the risks and benefits of drinking.

Patient knowledge and beliefs as barriers to extending cervical cancer screening intervals in Federally Qualified Health Centers.

OBJECTIVE: Despite guidelines recommending cervical cancer screening intervals be extended beyond one year, clinical practice has been slow to change. Patient preferences are a potential barrier. In the Centers for Disease Control's Cervical Cancer (Cx3) Study at Federally Qualified Health Centers (FQHCs) across Illinois, we surveyed patients about screening practices, and assessed beliefs regarding lengthening screening intervals. METHOD: We analyzed data from 984 low income women in the Cx3 Study (2009-2011). Participants completed a survey assessing health history, knowledge about Pap testing, beliefs and intentions about extending screening intervals, and demographics. RESULTS: The majority reported annual Pap testing (61%), while only 24% reported a 2-3 year screening interval (recommendation at time of survey). Misunderstandings about the Pap test were prevalent, with over half believing it screened for vaginal, yeast, and sexually transmitted infections (58%-72%). Unfavorable beliefs about extending screening intervals were common. The majority (57%) indicated that they would not wait 3 years to be screened if their physician recommended it, and intentions were associated with knowledge about Pap testing. CONCLUSION: Most women reported annual cervical cancer screening, and intended to resist longer screening intervals. Patients' lack of knowledge and unfavorable beliefs may serve as barriers to extending screening intervals.

Human Papillomavirus Detection in Scrotal Squamous Cell Carcinoma: Case Series from a Population-Based Cancer Registry.

Introduction: Scrotal squamous cell carcinomas (SCCs) are rare malignancies that are not considered to be associated with the human papillomavirus (HPV) by the International Agency for Research on Cancer. However, recent studies have detected HPV in these cancers. We sought to determine the presence of HPV types among scrotal cancer cases identified through population-based cancer registries. Methods: Primary scrotal SCCs diagnosed from 2014 to 2015 were identified, and tissue sections from formalin-fixed, paraffin-embedded tissue blocks were obtained for laboratory testing. A pathology review was performed to confirm morphology. HPV testing was performed using L1 consensus polymerase chain reaction analysis. Immunohistochemistry was used to evaluate p16INK4a (p16) expression. Results: Five cases of scrotal SCC were identified from 1 cancer registry. Age at diagnosis ranged from 34 to 75 years (median, 56 years). Four cases were non-Hispanic White, and 1 was non-Hispanic Black. The morphologic subtype of 4 cases was keratinizing (usual), and 1 case was verrucous (warty) histologic subtype. Two of the usual cases of SCC were HPV-negative and p16-negative, and 2 were positive for HPV16 and p16. The verrucous (warty) SCC subtype case was HPV6-positive and p16-negative. Conclusions: The presence of HPV16 and p16 overexpression in the examined tissue specimens lends additional support for the role of HPV in the etiology of scrotal SCC.

Concurrent partnerships, acute infection and HIV epidemic dynamics among young adults in Zimbabwe.

This paper explores the roles of acute infection and concurrent partnerships in HIV transmission dynamics among young adults in Zimbabwe using realistic representations of the partnership network and all published estimates of stage-specific infectivity. We use dynamic exponential random graph models to estimate partnership network parameters from an empirical study of sexual behavior and drive a stochastic simulation of HIV transmission through this dynamic network. Our simulated networks match observed frequencies and durations of short- and long-term partnerships, with concurrency patterns specific to gender and partnership type. Our findings suggest that, at current behavior levels, the epidemic cannot be sustained in this population without both concurrency and acute infection; removing either brings transmission below the threshold for persistence. With both present, we estimate 20-25% of transmissions stem from acute-stage infections, 30-50% from chronic-stage, and 30-45% from AIDS-stage. The impact of acute infection is strongly moderated by concurrency. Reducing this impact by reducing concurrency could potentially end the current HIV epidemic in Zimbabwe.

Factors associated with emergency medical services scope of practice for acute cardiovascular events.

OBJECTIVES: To examine prehospital emergency medical services (EMS) scope of practice for acute cardiovascular events and characteristics that may affect scope of practice; and to describe variations in EMS scope of practice for these events and the characteristics associated with that variability. METHODS: In 2008, we conducted a telephone survey of 1,939 eligible EMS providers in nine states to measure EMS agency characteristics, medical director involvement, and 18 interventions authorized for prehospital care of acute cardiovascular events by three levels of emergency medical technician (EMT) personnel. RESULTS: A total of 1,292 providers responded to the survey, for a response rate of 67%. EMS scope of practice interventions varied by EMT personnel level, with the proportion of authorized interventions increasing as expected from EMT-Basic to EMT-Paramedic. Seven of eight statistically significant associations indicated that EMS agencies in urban settings were less likely to authorize interventions (odds ratios <0.7) for any level of EMS personnel. Based on the subset of six statistically significant associations, fire department-based EMS agencies were two to three times more likely to authorize interventions for EMT-Intermediate personnel. Volunteer EMS agencies were more than twice as likely as nonvolunteer agencies to authorize interventions for EMT-Basic and EMT-Intermediate personnel but were less likely to authorize any one of the 11 interventions for EMT-Paramedics. Greater medical director involvement was associated with greater likelihood of authorization of seven of the 18 interventions for EMT-Basic and EMT-Paramedic personnel but had no association with EMT-Intermediate personnel. CONCLUSIONS: We noted statistically significant variations in scope of practice by rural vs. urban setting, medical director involvement, and type of EMS service (fire department-based/non-fire department-based; volunteer/paid). These variations highlight local differences in the composition and capacity of EMS providers and offer important information for the transition towards the implementation of a national scope of practice model.

A population study of screening history and diagnostic outcomes of women with invasive cervical cancer.

BACKGROUND: Despite advances to prevent and detect cervical cancer, national targets for screening have not been met in the United States. Previous studies suggested that approximately half of women who developed cervical cancer were not adequately screened. This study aimed to provide an updated examination of women's screening and diagnostic practices five years prior to an invasive cervical cancer diagnosis. METHODS: The study included women age 21 years and older diagnosed with invasive cervical cancer in 2013-2016 from three population-based state cancer registries in the United States. Medical records abstraction identified screening history and diagnostic follow-up. A mailed survey provided sociodemographic data. Screening was a Pap or human papillomavirus (HPV) test between 6 months and 5 years before diagnosis. Adequate follow-up was defined per management guidelines. RESULTS: Of the 376 women, 60% (n = 228) had not been screened. Among women who received an abnormal screening result (n = 122), 67% (n = 82) had adequate follow-up. Predictors of: (a) being screened were younger age, having a higher income, and having insurance; (b) adequate follow-up were having a higher income, and (c) stage 1 cervical cancer were being screened and younger age. CONCLUSION: Unlike other cancer patterns of care studies, this study uses data obtained from medical records supplemented with self-report information to understand a woman's path to diagnosis, her follow-up care, and the stage of her cervical cancer diagnosis. This study provides findings that could be used to reach more unscreened or under screened women and to continue lowering cervical cancer incidence in the United States.

Learning From Cervical Cancer Survivors: An Examination of Barriers and Facilitators to Cervical Cancer Screening Among Women in the United States.

BACKGROUND: Screening and timely follow-up have lowered cervical cancer incidence in the US; however, screening coverage, incidence, and death rates have remained fairly stable in recent years. Studies suggest that half of women diagnosed with cervical cancer don't receive appropriate screening prior to diagnosis; cervical cancer survivors can provide crucial insight into barriers and facilitators to screening. METHODS: Participants were cervical cancer survivors ≥21 years, identified through population-based central cancer registries (CR) in 3 US states or a social network (SN), Cervivor. CR participants completed a mailed survey on screening history, barriers, and facilitators to screening and sociodemographic data. SN participants completed the same survey online. RESULTS: CR participants (N = 480) were older, with a lower proportion of non-Hispanic white, married, and insured women compared to SN participants (N = 148). Fifty percent of CR and 79% of SN participants were screened 5 years prior to their diagnoses. Of those screened, 28% in both groups reported not following-up on abnormal results. For both groups, the most frequently identified screening barrier was that participants never imagined they would develop cervical cancer (percent agree CR = 76%; SN = 86%), and the facilitator was wanting to take care of their bodies (CR = 95%; SN = 94%). CONCLUSION: Addressing key barriers to obtaining screening and timely follow-up related to lack of knowledge of cervical cancer risk and screening tests and addressing insurance coverage in the design or modification of interventions may increase cervical cancer screening and lower cervical cancer incidence in the US.

What about the partners of women with abnormal Pap or positive HPV tests?

BACKGROUND: Because high-risk HPV is highly prevalent in the general population, usually transient, and rarely causes clinical symptoms, and because diagnostic and treatment options for HPV in men are lacking, partner notification is not useful for preventing transmission or protecting the health of male partners. METHODS: We conducted a nationally representative survey of clinicians in 7 specialties that perform cervical cancer screening. Providers were asked whether they recommend that women with an abnormal Pap or positive HPV test inform sex partners of the infection or refer partners to a clinician. RESULTS: A large proportion of providers in all 7 specialties encourage women with either an abnormal Pap or a positive HPV test to tell their sex partners to see a clinician, ranging from 48% to 73% across specialties. Providers who perform reflex HPV testing were more likely to recommend that patients with an ASCUS Pap inform their partners of test results if an HPV test was positive than if it was negative (66%-83% vs. 29%-50%); providers who perform adjunct HPV testing were more likely to recommend that patients with a normal Pap inform their partners if an HPV test was positive than if it was negative (72%-92% vs. 30%-52%). CONCLUSIONS: Most providers advise patients with cervical cancer screening tests suggestive of HPV infection to notify their sex partners and to refer them to a clinician. Guidelines are needed for providers to clarify any rationale for clinical evaluation of male partners, including that informing partners has a limited role in the control of HPV transmission or in preventing adverse health outcomes in the male partner.

Health care utilization by children with asthma.

INTRODUCTION: We examined how differences in health service utilization among children with asthma are associated with race/ethnicity, socioeconomic status (family income, mother's education), and health insurance coverage. METHODS: We analyzed Medical Expenditure Panel Survey data from 1996 through 2000 (982 children younger than 18 years with asthma). We calculated percentages and mean distributions, odds ratios, and incidence rate ratios. RESULTS: Non-Hispanic black children used more urgent care services and fewer preventive health services. Children in low-income families (125%-199% of the poverty line) had the lowest levels of prescription fills and general checkups. Children whose mothers had more education had more checkups and fewer emergency department visits. Children who were insured during the 2-year study period used more health services for asthma, not including emergency department visits. CONCLUSION: Minority children and children of socioeconomically disadvantaged families use more urgent care and less preventive care for asthma. Children without health insurance use fewer health services overall. Future research should address how related factors might explain health services utilization in effectively managing asthma in children.

Access of Black, Hispanic, and nonprivately insured women to liquid-based cytology, human papillomavirus DNA testing, and on-site colposcopy in the United States.

OBJECTIVE: To determine whether patient race, ethnicity, or insurance status was associated with access to cervical cancer screening with liquid-based cytology (LBC) and with human papillomavirus (HPV) DNA testing and with access to on-site colposcopy at the provider's principal practice site. MATERIALS AND METHODS: We conducted a nationally representative survey of clinicians in specialties that provide cervical cancer screening. Adjusted odds ratios (OR) were estimated for the associations between race, ethnicity, and insurance status of patients and provider use of LBC, HPV DNA testing, and on-site colposcopy. RESULTS: Providers who cared for >or=20% Hispanic patients were less likely to use LBC (OR 0.60, 95% CI=0.42-0.84). Providers who cared for >or=25% black women (OR 0.71, 95% CI=0.51-0.98) and providers who cared for <75% privately insured patients (OR 0.66, 95% CI=0.46-0.95) were less likely to use HPV DNA testing. Providers who cared for <75% privately insured patients were less likely to have on-site colposcopy (OR 0.57, 95% CI=0.37-0.89), but those who cared for >or=20% Medicaid patients were more likely to have on-site colposcopy (OR 1.86, 95% CI=1.26-2.73). CONCLUSIONS: Given the high rates of cervical cancer in minority women, access to cervical cancer screening and diagnostic follow-up must be ensured. It may also be beneficial to ensure affordable access to technologies such HPV DNA testing that increases the sensitivity of disease detection and to on-site colposcopy that facilitates follow-up of abnormal cytology.

Comparing Human Papillomavirus Prevalence in Rectal and Anal Cancer Using US Cancer Registries, 2014-2015.

BACKGROUND AND AIMS: Rectal squamous cell carcinoma (SCC) is a rare malignancy, and the causal role of human papillomavirus (HPV) in these cancers is thought to be similar to anal cancer. We compared type-specific prevalence of HPV in rectal SCC to anal cancer. In rectal SCC, we evaluated the agreement between HPV prevalence and positivity for p16, a marker of oncogenic activity. METHODS: A stratified random sample of rectal SCCs and anal cancers diagnosed between 2014 and 2015 were identified from 3 statewide cancer registries in Iowa, Kentucky, and Louisiana. HPV testing was performed at the HPV laboratory at the Centers for Disease Control and Prevention. HPV types were described using hierarchical attribution to HPV16 and other oncogenic types, weighted for sampling design. In rectal SCC, we computed concordance and Cohen's kappa coefficient (κ) between HPV status and p16 positivity. RESULTS: A total of 39 rectal and 72 anal cancers were analyzed. HPV16 was the most common type in both rectal and anal cancer and did not differ significantly between sites (71.4% vs 82.1%; P = .32). Concordance between the presence of any HPV type and p16 positivity in rectal SCC was 92% with κ = 0.77. CONCLUSIONS: Rectal SCC and anal cancer have similar type-specific HPV prevalence, with HPV16 found most frequently. Substantial agreement between p16 and HPV status in rectal SCC lends additional support for the etiologic role of HPV in both anal and rectal cancer. Larger studies could be conducted to replicate these findings.

Overview of Centers for Disease Control and Prevention's Case Investigation of Cervical Cancer Study.

Background: Despite advances in cervical cancer screening, a significant number of women in the United States have not received adequate screening. Studies have suggested that approximately half of the women who developed cervical cancer were not adequately screened. The Centers for Disease Control and Prevention (CDC) Case Investigation of Cervical Cancer (CICC) Study took a unique approach to reconstruct the time before a woman's cervical cancer diagnosis and understand the facilitators and barriers to screening and care. This article provides an overview of the study. Methods: This study included all cervical cancer survivors diagnosed with invasive cervical cancer aged 21 years and older in three U.S. states from 2014-2016. The study design consisted of three different data collection methods, including comprehensive registry data, a mailed survey, and medical chart abstraction. This overview compares the characteristics of cervical cancer survivors in the three states by study participation and eligibility status. Results: Registries identified 2,748 women diagnosed with invasive cervical cancer. Of these, 1,730 participants were eligible for participation, 28% (n = 481) enrolled in the study and 23% (n = 400) consented to the medical chart abstraction. Conclusion: The CICC Study is unique in that it addresses, with medical record verification, the medical history of woman 5 years before their cervical cancer diagnosis as well as provides information from the woman on her health care behaviors. This study provides data on a general population of cervical cancer survivors in three states that could be used to guide interventions to increase cervical cancer screening.

Does your child have asthma? Filled prescriptions and household report of child asthma.

INTRODUCTION: Surveys are central for information on asthma prevalence. Recently, the validity of parental reports of pediatric asthma has been questioned. Confidence is examined in the report of asthma for children, obtained in a survey from the adult household member most knowledgeable about household health care (MKA). METHOD: MKA reports of asthma are compared with pharmacy records of prescriptions beneficial in asthma treatment ("asthma medications") for children 0 to 17 years old in the 1996 Medical Expenditure Panel Survey. RESULTS: "Asthma medications" were filled for 6.5% of children, yet the MKA did not report asthma for 47.3% of them. However, for 61.2% of these children, the MKA reported plausible alternative medical conditions. For 9.0%, diagnosis information was missing. Among children with an "asthma medication," the MKA was less likely to report either asthma or a plausible alternative diagnosis for girls and for children 0 to 5 years of age. Reporting was not statistically different by child race/ethnicity, household income, education level, and MKA English language proficiency. DISCUSSION: Surveys do not overlook as many children with asthma as previously reported. Among children with "asthma medications," only sex and age appear to be different for children whose MKA reported either asthma or a plausible alternative diagnosis versus those whose MKA did not report either.

Change in Provider Beliefs Regarding Cervical Cancer Screening Intervals After an Educational Intervention.

BACKGROUND: Current cervical cancer screening guidelines include the option of lengthening the screening interval to 5 years for average-risk women aged 30-65 years when screened with Pap and human papillomavirus (HPV) test (co-test). Because many providers are reluctant to extend screening intervals, we launched an educational intervention to promote recommended screening practices. The study objective was to assess changes in provider attitudes and beliefs to extending screening intervals among low-income women. METHODS: The study was conducted in 15 clinics in Federally Qualified Health Centers in Illinois. Providers in the intervention arm received a multicomponent educational intervention. Fifty-six providers (n = 29 intervention and n = 27 control) completed baseline and 12-month follow-up surveys assessing beliefs and intentions about extending screening intervals. RESULTS: The 12-month assessment showed providers in the intervention arm were significantly more likely than those in the control arm to recommend a 3-year screening interval (guideline recommendation at time of study) with a normal co-test result. Providers who received the intervention were significantly more likely to agree that routine co-testing is the best way to screen for cervical cancer, that extending the screening interval would be good, easy, and beneficial, and to disagree that the increased screening interval would cause patients to lose contact with the medical system. CONCLUSION: Educating providers on the natural history of HPV infection and cervical cancer and the benefits of extended intervals increased their willingness to follow guidelines. This study provides evidence that an educational intervention delivered with HPV testing materials may be effective in encouraging appropriate cervical screening intervals.
