RESUMO

BACKGROUND: Complicating the COVID-19 pandemic are the healthcare disparities experienced by ethnic minorities, especially those with comorbidities including cancer. The introduction of COVID-19 vaccines has been instrumental in blunting the morbidity and mortality from the pandemic; however, vaccine hesitancy, particularly among ethnic minorities, has been a major concern. Thus, we sought to evaluate the knowledge and perspectives of COVID-19 and vaccines among our ethnic minority cancer patient population. METHODS: Following an IRB approved protocol, questionnaires were completed by patients in a predominantly ethnic minority population at a single institution between 1 February and 30 June 2021. Included were any adult cancer patients with either a solid or hematologic malignancy. RESULTS: Among the 84 patients that were offered the questionnaires, 52 patients responded, with a median age of 63.5 years. Overall, 36% were non-Hispanic Blacks and 30% were Hispanics; 65% were receiving active treatment for their cancer. Seventy-nine percent believed COVID-19 to be dangerous or harmful to them, 61% were concerned about the side effects, yet 65% considered COVID-19 vaccines as safe. Among the seven patients that refused the vaccine, (71%, n = 5) cited side effects and/or (57%, n = 4) believed that the vaccine was not needed. Overall, there was a significantly higher chance of being vaccinated if patients were receiving active cancer treatment, believed COVID-19 was harmful, or that the vaccine was safe, and knew COVID-19 was a virus. CONCLUSIONS: This exploratory study demonstrates that most ethnic minority cancer patients are receptive to vaccines, with a majority being vaccinated. However, we also discovered various reasons why this group of patients may not want be vaccinated, including concerns about side effects and perception that COVID-19 is not harmful. These findings can help us further understand the complex nature of vaccine hesitancy in ethnic minority cancer patients, and aid in developing future vaccine awareness strategies as the COVID-19 pandemic continues to evolve.

RESUMO

INTRODUCTION: Perioperative therapy is standard for patients with borderline-resectable pancreatic ductal adenocarcinoma (BR-PDAC); however, an optimal neoadjuvant regimen is lacking. We assessed the efficacy of FOLFIRINOX chemotherapy followed by gemcitabine-based chemoradiation as preoperative therapy. METHODS: Patients received 4 cycles of FOLFIRINOX, followed by 6-weekly gemcitabine with concomitant intensity-modulated radiation. The primary endpoint was the R0 resection rate. Secondary outcomes included resection rate, overall-response, overall survival (OS), progression-free survival (PFS), and tolerability. The trial was terminated early due to slow accrual. A Simon's optimal two-stage phase II trial single arm design was used. The primary hypothesis of treatment efficacy was tested using a multistage group sequential inference procedure. The secondary failure time analysis endpoints were assessed using the Kaplan-Meier procedure and the Cox regression model. RESULTS: A total of 22 patients enrolled in the study, 18 (81.8%) completed neoadjuvant treatment. The bias corrected R0 rate was 55.6% (90% CI: 33.3, 68.3; P value = .16) among patients that received at least 1 cycle of FOLFIRINOX and was 80% among patients that underwent surgery. The median OS was 35.1 months. The median PFS among patients that underwent surgery was 34 months. CONCLUSION: An R0 resection rate of 55.6% is favorable. Neoadjuvant FOLFIRINOX followed by concomitant Gemcitabine with radiation was well-tolerated. NCT01897454.

RESUMO

The goal of this study was to investigate the serological titers of circulating antibodies against human papillomavirus (HPV) type 16 (anti-HPV16) prior to the detection of an incident HPV16 or HPV31 infection amongst vaccinated participants. Patients were selected from a prospective post-HPV vaccine longitudinal cohort at Mount Sinai Adolescent Health Center in Manhattan, NY. We performed a nested case-control study of 43 cases with incident detection of cervical HPV16 (n = 26) or HPV31 (n = 17) DNA who had completed the full set of immunizations of the quadrivalent HPV vaccine (4vHPV). Two control individuals whom had received three doses of the vaccine (HPV16/31-negative) were selected per case, matched on age at the first dose of vaccination and follow-up time in the study: a random control, and a high-risk control that was in the upper quartile of a sexual risk behavior score. We conducted an enzyme-linked immunosorbent assay (ELISA) for the detection of immunoglobulin G (IgG) antibodies specific to anti-HPV16 virus-like particles (VLPs). The results suggest that the average log antibody titers were higher among high-risk controls than the HPV16/31 incident cases and the randomly selected controls. We show a prospective association between anti-HPV16 VLP titers and the acquisition of an HPV16/31 incident infection post-receiving three doses of 4vHPV vaccine.

RESUMO

Importance: Rates of human papillomavirus (HPV) infection have decreased since the introduction of HPV vaccines in populations with high vaccine uptake. Data are limited for adolescent and young adult populations in US metropolitan centers. Objective: To determine HPV infection rates in adolescent girls and young women aged 13 to 21 years in New York City following HPV vaccination. Design, Setting, and Participants: This cohort study of type-specific cervical HPV detection was conducted at a large adolescent-specific integrated health center in New York City between October 2007 and September 2019. Participants included an open cohort of adolescent girls and young adult women who received the HPV vaccine (Gardasil; Merck & Co) over a 12-year period following HPV vaccination introduction. Data analysis was concluded September 2019. Exposures: Calendar date and time since receipt of first vaccine dose. Main Outcomes and Measures: Temporal associations in age-adjusted postvaccine HPV rates. Results: A total of 1453 participants, with a mean (SD) age at baseline of 18.2 (1.4) years, were included in the cohort (African American with no Hispanic ethnicity, 515 [35.4%] participants; African American with Hispanic ethnicity, 218 [15.0%] participants; Hispanic with no reported race, 637 [43.8%] participants). Approximately half (694 [47.8%] participants) were vaccinated prior to coitarche. Age-adjusted detection rates for quadrivalent vaccine types (HPV-6, HPV-11, HPV-16, and HPV-18) and related types (HPV-31, and HPV-45) decreased year over year, with the largest effect sizes observed among individuals who had been vaccinated before coitarche (adjusted odds ratio [aOR], 0.81; 95% CI, 0.67-0.98). By contrast, detection was higher year over year for nonvaccine high-risk cervical HPV types (aOR, 1.08; 95% CI, 1.04-1.13) and anal HPV types (aOR, 1.11; 95% CI, 1.05-1.17). The largest effect sizes were observed with nonvaccine types HPV-56 and HPV-68. Conclusions and Relevance: Whereas lower detection rates of vaccine-related HPV types were observed since introduction of vaccines in female youth in New York City, rates of some nonvaccine high-risk HPV types were higher. Continued monitoring of high-risk HPV prevalence is warranted.

RESUMO

PURPOSE: The purpose of this study is to identify distinct neighborhood profiles patterned by key structural, physical, and social characteristics and test whether living in different profiles are associated with body mass index trajectories during adolescence in racial/ethnic minority female youth. METHODS: Participants were 1,328 sexually active female adolescents and young adults aged 14-23 years, predominately Hispanic and black, enrolled in an human papillomavirus type 4 vaccine (Gardasil) surveillance study at a large adolescent health clinic in New York City between 2007 and 2018. Body mass index was calculated from weight and height every 6 months. A comprehensive set of neighborhood structural, social, and physical characteristics from multiple national and state datasets was linked to each participant based on home address. RESULTS: Latent profile analysis revealed five distinct neighborhood profiles in New York City: High Structural/High Social Advantage, Moderate Advantage/Low Crime, Low SES (Socioeconomic Status)/High Activity, Low SES/High Social Advantage, and High Disadvantage. Results from multilevel growth curve analysis revealed that living in Low SES/High Activity neighborhoods was associated with a lower BMI at age 22 (b = -1.32, 95% confidence interval -2.49, -.16), as well as a slower increase in BMI from age 14 to 22 years (b = -.22, 95% confidence interval -.46, .02), compared to the High Disadvantage profile. CONCLUSIONS: Our findings suggest that improving neighborhood structural, social, and physical environments may help promote healthy weight and reduce health disparities during adolescence and young adulthood.

RESUMO

BACKGROUND: The United States has experienced an increasing divergence in cannabis, tobacco, and alcohol use among adolescents and young adults (AYA). We assessed the changes in cannabis, tobacco and alcohol use in an inner-city population of predominantly minority AYA females attending a large adolescent-specific health center in New York City. METHODS: This was a longitudinal study of AYA women recruited and followed over a twelve-year period between 2007 and 2019. Lifetime and past 30-day use were assessed by self-administered questionnaire every six months. In addition, we assessed associations with race, ethnicity, sexual behaviors, receipt of social services, living situation at home (e.g., with or without parents), and use of other drugs. RESULTS: Participants included 1549 AYA females aged 13-21 at baseline, 95% of whom were youth of color. Use of cannabis increased significantly over the twelve-year period, with frequent cannabis use (≥20 times in 30-days) increasing almost 18% per year (OR = 1.18; 95%CI:1.13-1.23). In contrast, past 30-day tobacco use declined over the same period (OR = 0.86; 95%CI:0.83-0.89). Past 30-day cannabis use was more likely among African Americans (OR = 1.33; 95%CI:1.08-1.63), women who had sex with both men and women compared to with men only (OR = 1.44; 95%CI:1.18-1.75), recent users of tobacco (OR = 2.20; 95%CI:1.92-2.52) and alcohol (OR = 2.84; 95%CI:2.52-3.20), and ever users of other drugs (OR = 1.69; 95%CI:1.44-1.99), independent of age, time and living situation. CONCLUSIONS: Increasing rates of cannabis use and the association with concurrent tobacco and alcohol use in AYA females underscore the need to screen for unhealthy cannabis use, in addition to tobacco and alcohol, especially among inner-city AYA.

RESUMO

INTRODUCTION: Radical prostatectomy (RP) is a standard treatment modality for localized prostate cancer. Biochemical failure after RP is usually evaluated with whole-body imaging to exclude distant metastatic disease, and pelvic magnetic resonance imaging (MRI) to detect local recurrence in the prostatectomy bed. The goal of this study is to correlate disease characteristics and demographic data in patients with rising prostate-specific antigen (PSA) after RP to determine association with MRI-detected cancer recurrence. METHODS: Sixty-four patients who underwent pelvic MRI for rising PSA after RP and had complete clinical and pathological data available were included. Using Chi-squared testing, we analyzed PSA levels, pathological disease characteristics (prostate cancer risk group, Gleason score, extracapsular extension, positive surgical margin, seminal vesicle involvement, perineural invasion, lymphovascular invasion, and PSA level before MRI), time from surgery to biochemical failure, and patient demographic characteristics as potential predictors of MRI-detected local recurrence. RESULTS: Definite MRI-detected local recurrence was observed in 17/64 patients (27%). Eleven (17%) patients had a suspicious lesion with the differential of scarring, retained seminal vesicle, or recurrent cancer. Thirty-six (56%) patients had no evidence of tumor in the prostate bed or pelvis on MRI. Patient race was associated with likelihood of detecting a prostate nodule on MRI (p=0.04), with African American patients having 82% lower odds of MRI-detected tumor recurrence compared with white patients (p=0.045). No other tumor or patient characteristic was significantly associated with MRI-detected recurrence. CONCLUSIONS: African American patients with biochemical failure after RP are less likely to have MRI-detectable recurrence in the prostate bed compared with white patients.

RESUMO

Importance: Hepatocellular carcinoma (HCC) is a heterogeneous disease with many available treatment modalities. Transarterial chemoembolization (TACE) is a valuable treatment modality for HCC lesions. This article seeks to evaluate the utility of additional ablative therapy in the management of patients with HCC who received an initial TACE procedure. Objective: To compare the overall survival (OS) and freedom from local progression (FFLP) outcomes after TACE alone with TACE that is followed by an ablative treatment regimen using stereotactic body radiation therapy, radiofrequency ablation, or microwave ablation for patients with HCC. Design, Setting, and Participants: This cohort study of 289 adults at a single urban medical center examined survival outcomes for patients with nonmetastatic, unresectable HCC who received ablative therapies following TACE or TACE alone from January 2010 through December 2018. The Lee, Wei, Amato common baseline hazard model was applied for within-patient correlation with robust variance and Cox regression analysis was used to assess the association between treatment group (TACE vs TACE and ablative therapy) and failure time events (FFLP per individual lesion and OS per patient), respectively. In both analyses, the treatment indication was modeled as a time-varying covariate. Landmark analysis was used as a further sensitivity test for bias by treatment indication. Exposures: TACE alone vs TACE followed by ablative therapy. Main Outcomes and Measures: Freedom from local progression and overall survival. Hypotheses were generated before data collection. Results: Of the 289 patients identified, 176 (60.9%) received TACE only and 113 (39.1%) received TACE plus ablative therapy. Ablative therapy included 45 patients receiving stereotactic body radiation therapy, 39 receiving microwave ablation, 20 receiving radiofrequency ablation, and 9 receiving a combination of these following TACE. With a median (interquartile range) follow-up of 17.4 (9.5-29.5) months, 242 of 512 (47.3%) lesions progressed, 211 in the group with TACE alone and 31 in the group with TACE plus ablative therapy (P < .001). Over 3 years, FFLP was 28.1% for TACE alone vs 67.4% for TACE with ablative therapy (P < .001). The 1-year and 3-year OS was 87.5% and 47.1% for patients with lesions treated with TACE alone vs 98.7% and 85.3% for patients where any lesion received TACE plus ablative therapy, respectively (P = .01), and this benefit remained robust on landmark analyses at 6 and 12 months. The addition of ablative therapy was independently associated with OS on multivariable analysis for all patients (hazard ratio, 0.26; 95% CI, 0.13-0.49; P < .001) and for patients with Barcelona clinic liver cancer stage B or C disease (hazard ratio, 0.31; 95% CI, 0.14-0.69; P = .004). Conclusions and Relevance: Adding ablative therapy following TACE improved FFLP and OS among patients with hepatocellular carcinoma. This study aims to guide the treatment paradigm for HCC patients until results from randomized clinical trials become available.

RESUMO

PURPOSE: The goal of this study was to evaluate the effect of pubertal timing, and its interaction with prior childhood maltreatment, on the risk of cervical human papillomavirus (HPV) among sexually active adolescent minority female adolescents and young adults. METHODS: This cross-sectional study includes 842 adolescent girls and young women (aged 12 to 20 years; predominately Black and Hispanic) enrolled in an HPV vaccine surveillance study at a large adolescent health clinic in New York City between 2007 and 2016. Pubertal timing was assessed by self-reported age at menarche at baseline, with "early" and "late" defined as one standard deviation below (<11 years) or above (>13 years) the mean. Childhood exposure to abuse (sexual, physical and emotional) and neglect (physical and emotional) was assessed using the Childhood Trauma Questionnaire. Over 40 types of HPV infection were detected using the polymerase chain reaction in cervical Pap specimens. RESULTS: Results from multivariable logistic regression showed that early and late pubertal timing were marginally associated with a higher risk of HPV infection, adjusting for demographic and health covariates. Childhood maltreatment moderated the association between early pubertal timing and HPV infection: early pubertal timing was associated with a higher risk for HPV infection among maltreated girls (OR = 3.32, 95%CI:1.61-6.85), but not among non-maltreated girls (OR = 0.96, 95%CI:0.61-1.50; p-interaction<0.01). CONCLUSIONS: Variation in the timing of puberty and history of childhood maltreatment may have implications for adolescent sexual and reproductive health. Findings suggest that clinicians need to assess the biological and psychosocial risks in caring for youth.

RESUMO

Importance: Human papillomavirus (HPV) is the most common sexually transmitted infection in the United States, and oral HPV infection is associated with increased risk of oropharyngeal cancer. Objective: To describe the risk factors for oral HPV in sexually active female adolescents receiving the quadrivalent vaccine. Design, Setting, and Participants: Longitudinal cohort study involving repeated collection of oral rinse specimens from sexually active female adolescents conducted between October 19, 2007, and March 9, 2017, at a large adolescent health center in New York, New York, that provides free health care, including HPV vaccination. Exposures: Human papillomavirus vaccination and self-reported history of sexual behavior. Main Outcomes and Measures: Prevalence of HPV in the oral cavity. Results: Among the 1259 participants who were included in this study, median age at entry into the study was 18 (range, 13-21) years; 638 (50.7%) were of African American descent, 569 (45.2%) were of Hispanic descent, 43 (3.4%) reported another race/ethnicity, and race/ethnicity was unspecified for 9 (0.7%). The median (mode) age at first sexual activity was 14.8 (14) years, and 1161 (92.2%) reported having had oral sex. Human papillomavirus DNA was detected in baseline oral rinse samples of 78 of the 1259 participants (6.2%; 95% CI, 4.9%-7.6%). There was a significant decrease in oral HPV detection with time (in years) since first engaging in sexual activities, independent of age and concurrent detection of cervical HPV; comparing 4 or more years with 1 year or less, the odds ratio was 0.45 (95% CI, 0.21-0.96). Detection of vaccine types (HPV-6, HPV-11, HPV-16, and HPV-18) was significantly lower among participants who had received at least 1 dose of the quadrivalent HPV vaccine at the time of enrollment compared with those who were unvaccinated (odds ratio, 0.20; 95% CI, 0.04-0.998). Conclusions and Relevance: This study's findings suggest that detection of HPV in the oral cavity is not uncommon in sexually active female adolescents. In addition, HPV vaccination is associated with a significant decrease in detection of HPV vaccine types in the oral cavity.

RESUMO

OBJECTIVE: We prospectively evaluated patients with completely resected uterine serous carcinoma (USC) treated with radiation "sandwiched" between carboplatin/paclitaxel (C/T). The primary objective was to determine the safety profile, and the secondary outcome was to evaluate progression-free and overall survival. METHODS: Surgically staged patients with completely resected USC were enrolled to receive 3 cycles of paclitaxel 175 mg/m and carboplatin (area under the curve, 6-7.5) every 21 days, followed by radiotherapy and an additional 3 cycles of T/C at area under the curve of 5-6 (6 cycles + radiotherapy). Toxicity was graded according to National Cancer Institute Common Toxicity Criteria, version 4.03. Kaplan-Meier and log-rank tests were used to compare survival probabilities. RESULTS: One hundred forty patients were enrolled, of which 132 were evaluable, completed at least 3 cycles of chemotherapy and radiation. One hundred seven (81%) completed 6 cycles of chemotherapy and radiation. Patients with early-stage (I/II) disease have survival probabilities of 0.96 and 0.81 at 2 and 5 years. Patients with stage I USC and lymphovascular invasion have considerably worse overall survival, with 2.7 times' higher risk of death than those without lymphovascular invasion. Patients with late-stage (III/IV) disease had overall survival probabilities of 0.64 and 0.18 at 2 and 5 years, which is far higher survival than what has been reported in single-modality trials. Interestingly, and different than what is reported in other studies, there is no difference in survival in African Americans versus whites/other races who were evaluable. Of the 779 cycles administered, 22% and 14% of cycles were associated with grades 3 and 4 hematologic toxicities, respectively. Grades 3 and 4 nonhematologic toxicities occurred in 6.9% of cycles. CONCLUSIONS: The long-term follow-up in this study demonstrates that "sandwich" therapy is an efficacious, well-tolerated treatment approach with acceptable toxicities. Lymphovascular invasion (LVSI) is a significantly poor prognostic factor in stage I USC. Multimodal "sandwich" therapy should be considered in all USC patients who have undergone complete surgical resection and staging.

RESUMO

OBJECTIVE: Endometrial cancer survivors are the least physically active of all cancer survivor groups and exhibit up to 70% obesity. While studies suggest lifestyle interventions result in improved health outcomes, recruitment and availability of these programs are limited. The purpose was to evaluate the acceptability and validity of the Fitbit Alta™ physical activity monitor (Fitbit) for socioculturally diverse endometrial cancer survivors. METHODS: Thirty endometrial cancer survivors were given wrist-worn Fitbits to wear for 30 days. Participants then returned the Fitbits, completed the Godin Leisure-Time Exercise Questionnaire (GLTEQ), Technology Acceptance Questionnaire, and answered qualitative prompts. Correlations between daily Fitbit step counts, demographic factors, body mass index (BMI), and GLTEQ Index, were analyzed using Stata 13.0. Concordance Correlation Coefficient using U statistics was used to examine convergent validity. RESULTS: Twenty-five participants completed the study. Mean age was 62 ±â€¯9 years. Mean BMI was 32 ±â€¯9 kg·m-2. Self-identified race/ethnicity was 36% Hispanic, 36% non-Hispanic white, 16% non-Hispanic black and 12% Asian. Participants wore the Fitbits a median of 93% of possible days. Median daily Fitbit step count was 5325 (IQR: 3761-8753). Mean Technology Acceptance score was 2.8 ±â€¯0.5 out of 4.0. Younger (<65 years) and employed participants were more likely to achieve at least 6000 daily steps (p < 0.05). There was no correlation (CCC = 0.00, p = 0.99) between step count and GLTEQ Index. Most free responses reflected positive experiences. CONCLUSIONS: The Fitbits were well accepted in this sample. Self-reported physical activity was not associated with steps recorded. The physical activity data indicate an insufficiently active population.

RESUMO

PURPOSE: To perform a prospective trial examining positron emission tomography (PET)-based, dose-painted intensity modulated radiation therapy (IMRT) in the setting of locally advanced non-small cell lung cancer (NSCLC). METHODS AND MATERIALS: Patients with stage IIB-III NSCLC were treated with 25 fractions of dose-painted IMRT. Tumors or lymph nodes with metabolic tumor volume exceeding 25 cm3 were deemed "high risk" and received 65 Gy. Smaller lesions were treated with 57 Gy or 52.5 Gy (after November 2014). Patients received concurrent weekly carboplatin (area under the curve = 2) and paclitaxel (45 mg/m2). The primary study endpoint was the absence of high residual metabolic activity (maximum standardized uptake value > 6) in treated lesions on PET 12 to 16 weeks after completion of IMRT. RESULTS: Thirty-five subjects with 116 hypermetabolic lesions were eligible for analysis. The primary endpoint was met for 24 of 30 patients (80%) who underwent posttreatment PET, satisfying our efficacy objective. With a median follow-up duration of 23.8 months for living patients, progression in a lesion targeted with radiation therapy has been observed in 5 patients (14%). Treating progression in other sites and death without progression as competing risks, 2-year cumulative incidence rates of local disease progression in high-risk lesions (n=24) and low-risk lesions (n=92) are 9% and 3%, respectively. The actuarial rate of overall survival at 2 years is 52%. CONCLUSIONS: Dose-painted IMRT based on pretreatment PET metrics with concurrent chemotherapy yields high rates of metabolic response and local disease control for locally advanced NSCLC. Future trials should test this approach to maximize the therapeutic ratio of thoracic radiation therapy.

RESUMO

BACKGROUND: Childhood physical abuse is a major public health issue with negative consequences to health and well-being manifested in childhood and adolescence, and persisting into adulthood. Yet much childhood physical abuse is not identified when it occurs and little is known about how to screen for it. METHODS: To address this gap, the effectiveness of 4 modes of administration of screens to identify childhood physical abuse were compared in a sample of 506 adolescents and young adults aged 12-24 years seeking general health services at a primary care clinic. Comparisons were made between paper and pencil screen, audio computer-assisted self-interview screen, face-to-face structured screen (all 3 using the same measure), and face-to-face unstructured interview. FINDINGS: Overall, 44.5% of the sample disclosed that they had been physically abused. Compared to paper and pencil screen, the odds of reporting physical abuse were 1.5 (95% confidence interval [CI]: 0.92, 2.58) and 4.3 (95% CI: 2.49, 7.43) higher among participants using face-to-face structured screen and face-to-face unstructured interview methods, respectively. The face-to-face unstructured interview identified significantly more reports than the paper and pencil screen. CONCLUSIONS: Although the unstructured interview was the most effective mode for screening for childhood physical abuse, additional research is needed to confirm whether this holds true in other health care settings. Further research should examine how a health provider's training, experience, and comfort level might influence the identification of physical abuse disclosure in primary care settings using face-to-face unstructured interview.

RESUMO

PURPOSE: To perform a prospective trial testing the feasibility and utility of acquiring activity data as a measure of health status during concurrent chemoradiotherapy. METHODS AND MATERIALS: Ambulatory patients who were planned for treatment with concurrent chemoradiotherapy with curative intent for cancers of the head and neck, lung, or gastrointestinal tract were provided with activity monitors before treatment initiation. Patients were asked to wear the devices continuously throughout the radiation therapy course. Step count data were downloaded weekly during radiation therapy and 2 and 4 weeks after radiation therapy completion. The primary objective was to demonstrate feasibility, defined as collection of step counts for 80% of the days during study subjects' radiation therapy courses. Secondary objectives included establishing step count as a dynamic predictor of unplanned hospitalization risk. RESULTS: Thirty-eight enrolled patients were treated with concurrent chemoradiotherapy. Primary diagnoses included head and neck cancer (n=11), lung cancer (n=13), and a variety of gastrointestinal cancers (n=14). Step data were collected for 1524 of 1613 days (94%) during patients' radiation therapy courses. Fourteen patients were hospitalized during radiation therapy or within 4 weeks of radiation therapy completion. Cox regression modeling demonstrated a significant association between recent step counts (3-day average) and hospitalization risk, with a 38% reduction in the risk of hospitalization for every 1000 steps taken each day (hazard ratio 0.62, 95% confidence interval 0.46-0.83, P=.002). Inferior quality of life scores and impaired performance status were not associated with increased hospitalization risk. CONCLUSION: Continuous activity monitoring during concurrent chemoradiotherapy is feasible and well-tolerated. Step counts may serve as powerful, objective, and dynamic indicators of hospitalization risk.

RESUMO

BACKGROUND: Cancers constitute a significant public health problem in Nigeria. Breast, cervix and prostate cancers are leading causes of cancer-related deaths. Changing diets, lifestyles, HIV/AIDS and macro-structural factors contribute to cancer morbidity and mortality. Poor health information linking cancer risk to individual behaviors, environmental pollutants and structural barriers undermine prevention/control efforts. Studies suggest increasing health literacy and empowering individuals to take preventive action will improve outcomes and mitigate impact on a weak health system. METHODS: We obtained qualitative data from 80 men, women, and young adults in 11 focus groups to assess beliefs, risk-perceptions, preventive behaviors and perceptions of barriers and facilitators to cancer control in Ibadan, Nigeria and conducted thematic analysis. RESULTS: Participants demonstrated awareness of cancers and mentioned several risk factors related to individual behaviors and the environment. Nonetheless, myths and misconceptions as well as micro, meso and macro level barriers impede prevention and control efforts. CONCLUSION: Developing and implementing comprehensive context-relevant health literacy interventions in community settings are urgently needed.Copyright © 2016 John Wiley & Sons, Ltd.

RESUMO

BACKGROUND: Uptake of human papillomavirus (HPV) vaccine in the United States is slow, and the effectiveness of the vaccine has not been assessed in high-risk adolescent populations. METHODS: We conducted a longitudinal study of 1139 sexually active, inner-city adolescent women receiving the 3-dose quadrivalent (4vHPV) vaccine. Cervical and anal specimens collected semiannually were tested using an L1-specific polymerase chain reaction assay. Postvaccination incidence of 4vHPV vaccine and nonvaccine HPV types, and risk of cervical cytological abnormalities, were assessed in relation to time to completion of all 3 vaccine doses. RESULTS: Compared to vaccine naive women at enrollment, vaccinated women had significantly lower incidence rate ratios of cervical infection with HPV6/11/16/18 (0.2; 95% confidence interval [CI], .1-.4) and the related types HPV31 and HPV45 (0.4 [95% CI, .2-1.0] and 0.3 [95% CI, .1-.6], respectively), as well as significantly lower incidence rate ratios of anal infection with HPV6/11/16/18 (0.4; 95% CI, .2-.7). Notably, we observed higher risks of cervical HPV6/11/16/18 infection (hazards ratio [HR], 2.9; 95% CI, 1.0-8.0) and associated cytological abnormalities (HR, 4.5; 95% CI, .7-26.0) among women immunized at ≥15 years of age who took ≥12 months (vs <12 months) to complete the 3-dose regimen. CONCLUSIONS: Among adolescents immunized at ≥15 years of age, a longer time to complete the 3-dose schedule was associated with an increased risk of anogenital HPV6/11/16/18 infection and an increased incidence of associated cervical cytological abnormalities.

RESUMO

PURPOSE: Determine the feasibility of a 12-week physical activity intervention for obese, socioculturally diverse endometrial cancer survivors and to evaluate whether the intervention improves physical activity behavior, physical function, waist circumference, and quality of life. METHODS: Obese endometrial cancer survivors from Bronx, NY were assigned to either a 12-week physical activity intervention of behavioral counseling, physical activity and home-based walking (n=25), or wait-list control group (n=15). Mixed-design ANOVA (2 groups×2 time points) were analyzed to determine differences between the intervention and the control for the Yale Physical Activity Survey, six-minute walk test, 30-second chair stand test, waist circumference, and Functional Assessment of Cancer Therapy-Endometrial questionnaire. Data are presented as mean±standard deviation. RESULTS: The sample was diverse (38% non-Hispanic black, 38% Hispanic, 19% non-Hispanic white). Mean Body Mass Index was 37.3±6.5kg·m(-2). Although recruitment rate was low (20% of 140 contacted), 15 of 25 participants in the intervention group attended 75-100% of scheduled sessions. Participants reported walking 118±79min/week at home. There were large effect sizes for the improvements in the six-minute walk test (22±17m vs. 1±22m, d=1.10), waist circumference (-5.3±5.3cm vs. 2.6±6.7cm, d=-1.32), quality of life (10±12 vs. -1±11, d=0.86) and walking self-efficacy (24±30% vs. 1±55%, d=0.87) compared to the control group. CONCLUSIONS: The intervention appeared feasible in this population. The results show promising effects on several outcomes that should be confirmed in a larger randomized control trial, with more robust recruitment strategies.

RESUMO

OBJECTIVE: To examine the association of knowledge about human papillomavirus (HPV) on the time to completion of the 3-dose quadrivalent vaccine series in an inner-city population of adolescent female subjects at high risk for infection. STUDY DESIGN: We prospectively followed 139 female subjects aged 14-20 years enrolled in a vaccine surveillance study in New York City during a period of at least 24 months. Participants were given a 30-item true or false survey on HPV at enrollment and ranked according to the number of correct responses. Multivariate Cox regression was used to examine the association between level of knowledge about HPV and time to completion (in days) of vaccine dose 1-3, dose 1-2, and dose 2-3. RESULTS: Overall time to completion of the 3-dose vaccine ranged from 158 days to 1114 days. Participants in the high knowledge group (top quartile) were significantly more likely to complete the 3-dose series earlier (hazard ratio 1.69, 95% CI 1.03-2.77; P = .04), in particular doses 2-3 (hazard ratio 1.71, 95% CI 1.02-2.89; P = .04), than those with low-to-moderate knowledge (bottom 3 quartiles). CONCLUSIONS: These findings suggest that knowledge of HPV is associated with shorter time to complete the 3-dose HPV vaccine series. Educational campaigns at time of vaccination may be important to improve vaccine adherence.
