RESUMEN

Chronic disruption of circadian rhythms by night shift work is associated with an increased breast cancer risk. However, little is known about the impact of night shift on peripheral circadian genes (CGs) and circadian-controlled genes (CCGs) associated with breast cancer. Hence, we assessed central clock markers (melatonin and cortisol) in plasma, and peripheral CGs (PER1, PER2, PER3, and BMAL1) and CCGs (ESR1 and ESR2) in peripheral blood mononuclear cells (PBMCs). In day shift nurses (n = 12), 24-h rhythms of cortisol and melatonin were aligned with day shift-oriented light/dark schedules. The mRNA expression of PER2, PER3, BMAL1, and ESR2 showed 24-h rhythms with peak values in the morning. In contrast, night shift nurses (n = 10) lost 24-h rhythmicity of cortisol with a suppressed morning surge but retained normal rhythmic patterns of melatonin, leading to misalignment between cortisol and melatonin. Moreover, night shift nurses showed disruption of rhythmic expressions of PER2, PER3, BMAL1, and ESR2 genes, resulting in an impaired inverse correlation between PER2 and BMAL1 compared to day shift nurses. The observed trends of disrupted circadian markers were recapitulated in additional day (n = 20) and night (n = 19) shift nurses by measurement at early night and midnight time points. Taken together, this study demonstrated the misalignment of cortisol and melatonin, associated disruption of PER2 and ESR2 circadian expressions, and internal misalignment in peripheral circadian network in night shift nurses. Morning plasma cortisol and PER2, BMAL1, and ESR2 expressions in PBMCs may therefore be useful biomarkers of circadian disruption in shift workers.

RESUMEN

BACKGROUND AND AIM: Placental efflux transporter proteins, such as BCRP, reduce the placental and fetal toxicity of environmental contaminants but have received little attention in perinatal environmental epidemiology. Here, we evaluate the potential protective role of BCRP following prenatal exposure to cadmium, a metal that preferentially accumulates in the placenta and adversely impacts fetal growth. We hypothesized that individuals with a reduced function polymorphism in ABCG2, the gene encoding BCRP, would be most vulnerable to the adverse impacts of prenatal cadmium exposure, notably, smaller placental and fetal size. METHODS: We measured cadmium in maternal urine samples at each trimester and in term placentas from UPSIDE-ECHO study participants (NY, USA; n = 269). We fit adjusted multivariable linear regression and generalized estimating equation models to examine log-transformed urinary and placental cadmium concentrations in relation to birthweight, birth length, placental weight, and fetoplacental weight ratio (FPR) and stratified models by ABCG2 Q141K (C421A) genotype. RESULTS: Overall 17% of participants expressed the reduced-function ABCG2 C421A variant (AA or AC). Placental cadmium concentrations were inversely associated with placental weight (ß = -19.55; 95%CI: -37.06, -2.04) and trended towards higher FPR (ß = 0.25; 95%CI: -0.01, 0.52) with stronger associations in 421A variant infants. Notably, higher placental cadmium concentrations in 421A variant infants were associated with reduced placental weight (ß = -49.42; 95%CI: 98.87, 0.03), and higher FPR (ß = 0.85, 95%CI: 0.18, 1.52), while higher urinary cadmium concentration was associated with longer birth length (ß = 0.98; 95%CI: 0.37, 1.59), lower ponderal index (ß = -0.09; 95%CI: 0.15, -0.03), and higher FPR (ß = 0.42; 95%CI: 0.14, 0.71). CONCLUSIONS: Infants with reduced function ABCG2 polymorphisms may be particularly vulnerable to the developmental toxicity of cadmium as well as other xenobiotics that are BCRP substrates. Additional work examining the influence of placental transporters in environmental epidemiology cohorts is warranted.

RESUMEN

INTRODUCTION: People believe that cigarettes using 'organic,' 'additive-free' or similar descriptors are less harmful than other cigarettes. Natural American Spirit (NAS) is the most popular US cigarette brand using these descriptors. This cohort study describes changes in US smokers' odds of preferring NAS and changes in NAS smokers' odds of believing their brand might be less harmful than other brands. METHODS: Data come from four waves (2013-2018) of the Population Assessment of Tobacco and Health (PATH) Study. Generalised estimating equations produced population-averaged estimates of relationships between (1) NAS brand preference and wave and (2) belief that one's own brand might be less harmful than other brands, wave and NAS brand preference. Models tested interactions by age group and sexual minority status. RESULTS: The odds that smokers preferred NAS increased by 60% in W4 relative to W1. Disproportionate preference by younger adult and sexual minority smokers was observed. The odds that NAS smokers believed their own brand might be less harmful decreased by 50% between W1 and W4, but this perception was still 16 times higher for NAS compared with non-NAS smokers. Given the increasing preference for NAS, there was no significant change in the absolute number of NAS smokers who believed their own brand might be less harmful (W1: 562 122 (95% CI 435 190 to 689 055) vs W4: 580 378 (95% CI 441 069 to 719 689)). CONCLUSIONS: Both brand popularity and concentration of brand-related harm perceptions are important for understanding population impact of changes in cigarette marketing.

RESUMEN

INTRODUCTION: While previous research has examined misperceptions related to Natural American Spirit (NAS), a premium cigarette brand using 'natural'-themed marketing, the longitudinal relationship between NAS-related harm beliefs and switching to NAS has not been established. METHODS: Using data from the PATH study, we modelled the longitudinal relationship between (1) brand switching and subsequent belief that one's own brand might be less harmful than other brands (Waves 1-5); (2) belief that organic and/or additive-free tobacco products are less harmful and subsequent brand switching (Waves 3-5); and (3) belief that some types of cigarettes are less harmful and subsequent brand switching (Waves 3-5) for NAS and two leading comparator brands (Camel and Marlboro). RESULTS: Among people who did not think their prior brand might be less harmful, switching to NAS or maintaining NAS preference increased the odds of believing one's own brand might be less harmful (aOR 19.4; 95% CI: 15.19, 24.8; aOR 6.1; 95% CI: 4.23, 8.67, respectively). Prior belief that organic and additive-free tobacco products were less harmful increased the odds of switching to (aOR 2.5; 95% CI: 1.68, 3.74) and decreased the odds of switching away (0.57; 955 CI: 0.36, 0.92) from NAS in the subsequent wave. Parallel analyses for Marlboro/Camel were largely null or in the opposite direction. CONCLUSIONS: NAS use may maintain or shape new beliefs that the brand may be less harmful than other brands; holding pre-existing beliefs about the relative harm of some tobacco products may increase risk for NAS use.

RESUMEN

Individuals with COVID-19 who do not require hospitalization are instructed to self-isolate in their residences. Due to high secondary infection rates in household members, there is a need to understand airborne transmission of SARS-CoV-2 within residences. We report the first naturalistic intervention study suggesting a reduction of such transmission risk using portable air cleaners (PACs) with HEPA filters. Seventeen individuals with newly diagnosed COVID-19 infection completed this single-blind, crossover, randomized study. Total and size-fractionated aerosol samples were collected simultaneously in the self-isolation room with the PAC (primary) and another room (secondary) for two consecutive 24-h periods, one period with HEPA filtration and the other with the filter removed (sham). Seven out of sixteen (44%) air samples in primary rooms were positive for SARS-CoV-2 RNA during the sham period. With the PAC operated at its lowest setting (clean air delivery rate [CADR] = 263 cfm) to minimize noise, positive aerosol samples decreased to four out of sixteen residences (25%; p = 0.229). A slight decrease in positive aerosol samples was also observed in the secondary room. As the world confronts both new variants and limited vaccination rates, our study supports this practical intervention to reduce the presence of viral aerosols in a real-world setting.

RESUMEN

BACKGROUND: Maternal education has been shown repeatedly to be inversely associated with preterm birth. Both preterm birth and educational level of families are correlated across generations, but it is not clear if educational level of grandparents affects the risk of preterm delivery of their grandchildren, and, if so, if the association with grandmother's education is independent of mother's education. METHODS: We used New Jersey birth certificates to create a transgenerational dataset to examine the effect of grandmother's education on risk of PTB in White, Black and Hispanic grandchildren. We matched birth certificates of girls born in 1979-1983 to mothers listed on NJ birth certificates for the years 1999-2011. Thus, grandmothers were the women delivering in 1979-1983, and mothers were those born to the grandmothers who in turn delivered grandchildren in 1999-2011. We performed descriptive tabulations and multivariate logistic regression to develop risk estimates. RESULTS: Overall, maternal education was associated inversely with PTB in each of the demographic groups. There was a substantial inter-generational increase in education between grandmothers and mothers in each group, which was most striking in Hispanics After adjusting for maternal age and education, grandmother's education continued to be associated with preterm birth of her grandchildren. CONCLUSIONS: Grandmother's education was an additional, independent predictor of PTB in her grandchildren. This result supports the idea that mother's childhood and preconception socioeconomic environment, including the educational level of her childhood household affect her reproductive health.

RESUMEN

Understanding information seeking behaviors and experiences is essential for designing educational and supportive interventions to promote survivor's self-management post treatment. This study examined health and cancer information seeking, use of internet to find cancer information, and information seeking experiences among breast, colorectal, and prostate cancer survivors. Nationally representative data collected in 2017-2018 from 2 cycles of the Health Information National Trends Survey (HINTS 5, cycles 1 and 2 were merged with combined replicate weights using the jackknife replication method (n = 373). Regression analysis for three information seeking behaviors (i.e., health information, cancer information, and internet for cancer information) were modeled, including sociodemographic and clinical factors as predictors. In addition, separate regression analysis predicted three experiences of information seeking (effort, quality, and hard to understand) with sociodemographic and clinical factors. A majority of survivors (84.7%) sought health information. Factors significantly associated with seeking health information were gender (p = 0.024), education (p = 0.0021), and income (p = 0.018). Only 38% of survivors used the internet to seek cancer-related information. The only factor significantly associated with using the internet to seek cancer-related information was time since diagnosis (p = 0.0002). The factor significantly associated with difficulty understanding information was annual household income (p = 0.026). This study fills an important gap by identifying sociodemographic and cancer-related factors associated with information seeking behaviors and experiences. These findings highlight a need to tailor information for low socioeconomic status survivors to account for the lack of skills, resources, and motivation to seek information about health and cancer related topics independently.

RESUMEN

BACKGROUND: This study evaluated the feasibility of a technology-enhanced group-based fitness intervention for adolescent and young adult (AYA) survivors of childhood cancer. PROCEDURE: AYA survivors ages 13-25 years were randomized to the intervention (eight in-person group sessions with mobile app and FitBit followed by 4 weeks of app and FitBit only) or waitlist control. Assessments were at 0, 2, 3, 6, and 9 months. Feasibility was evaluated by enrollment, retention, attendance, app engagement, and satisfaction. Secondary outcomes included physical activity, muscular strength/endurance, cardiorespiratory fitness, health-related quality of life, and fatigue. RESULTS: A total of 354 survivors were mailed participation letters; 68 (19%) were screened, of which 56 were eligible and 49 enrolled (88% of those screened eligible, 14% of total potentially eligible). Forty-nine survivors (Mage  = 18.5 years, 49% female) completed baseline assessments and were randomized (25 intervention, 24 waitlist). Thirty-seven (76%) completed the postintervention assessment and 32 (65%) completed the final assessment. On average, participants attended 5.7 of eight sessions (range 1-8). Overall intervention satisfaction was high (M = 4.3, SD = 0.58 on 1-5 scale). Satisfaction with the companion app was moderately high (M = 3.4, SD = 0.97). The intervention group demonstrated significantly greater improvement in lower body muscle strength compared to the waitlist postintervention, and small but not statistically significant changes in other secondary measures. CONCLUSIONS: A group-based intervention with a mobile app and fitness tracker was acceptable but has limited reach due to geographical barriers and competing demands experienced by AYA survivors.

RESUMEN

BACKGROUND: Long-term exposure to pollution can lead to an increase in the rate of decline of lung function, especially in older individuals and in those with chronic obstructive pulmonary disease (COPD), whereas shorter-term exposure at higher pollution levels has been implicated in causing excess deaths from ischaemic heart disease and exacerbations of COPD. We aimed to assess the effects on respiratory and cardiovascular responses of walking down a busy street with high levels of pollution compared with walking in a traffic-free area with lower pollution levels in older adults. METHODS: In this randomised, crossover study, we recruited men and women aged 60 years and older with angiographically proven stable ischaemic heart disease or stage 2 Global initiative for Obstructive Lung Disease (GOLD) COPD who had been clinically stable for 6 months, and age-matched healthy volunteers. Individuals with ischaemic heart disease or COPD were recruited from existing databases or outpatient respiratory and cardiology clinics at the Royal Brompton & Harefield NHS Foundation Trust and age-matched healthy volunteers using advertising and existing databases. All participants had abstained from smoking for at least 12 months and medications were taken as recommended by participants' doctors during the study. Participants were randomly assigned by drawing numbered disks at random from a bag to do a 2 h walk either along a commercial street in London (Oxford Street) or in an urban park (Hyde Park). Baseline measurements of participants were taken before the walk in the hospital laboratory. During each walk session, black carbon, particulate matter (PM) concentrations, ultrafine particles, and nitrogen dioxide (NO2) concentrations were measured. FINDINGS: Between October, 2012, and June, 2014, we screened 135 participants, of whom 40 healthy volunteers, 40 individuals with COPD, and 39 with ischaemic heart disease were recruited. Concentrations of black carbon, NO2, PM10, PM2.5, and ultrafine particles were higher on Oxford Street than in Hyde Park. Participants with COPD reported more cough (odds ratio [OR] 1·95, 95% CI 0·96-3·95; p<0·1), sputum (3·15, 1·39-7·13; p<0·05), shortness of breath (1·86, 0·97-3·57; p<0·1), and wheeze (4·00, 1·52-10·50; p<0·05) after walking down Oxford Street compared with Hyde Park. In all participants, irrespective of their disease status, walking in Hyde Park led to an increase in lung function (forced expiratory volume in the first second [FEV1] and forced vital capacity [FVC]) and a decrease in pulse wave velocity (PWV) and augmentation index up to 26 h after the walk. By contrast, these beneficial responses were attenuated after walking on Oxford Street. In participants with COPD, a reduction in FEV1 and FVC, and an increase in R5-20 were associated with an increase in during-walk exposure to NO2, ultrafine particles and PM2.5, and an increase in PWV and augmentation index with NO2 and ultrafine particles. In healthy volunteers, PWV and augmentation index were associated both with black carbon and ultrafine particles. INTERPRETATION: Short-term exposure to traffic pollution prevents the beneficial cardiopulmonary effects of walking in people with COPD, ischaemic heart disease, and those free from chronic cardiopulmonary diseases. Medication use might reduce the adverse effects of air pollution in individuals with ischaemic heart disease. Policies should aim to control ambient levels of air pollution along busy streets in view of these negative health effects. FUNDING: British Heart Foundation.

RESUMEN

RATIONALE: Associations between urban (outdoor) airborne particulate matter (PM) exposure and TB and potential biological mechanisms are poorly explored. OBJECTIVES: To examine whether in vivo exposure to urban outdoor PM in Mexico City and in vitro exposure to urban outdoor PM2.5 (< 2.5 µm median aerodynamic diameter) alters human host immune cell responses to Mycobacterium tuberculosis. METHODS: Cellular toxicity (flow cytometry, proliferation assay (MTS assay)), M. tuberculosis and PM2.5 phagocytosis (microscopy), cytokine-producing cells (Enzyme-linked immune absorbent spot (ELISPOT)), and signalling pathway markers (western blot) were examined in bronchoalveolar cells (BAC) and peripheral blood mononuclear cells (PBMC) from healthy, non-smoking, residents of Mexico City (n=35; 13 female, 22 male). In vivo-acquired PM burden in alveolar macrophages (AM) was measured by digital image analysis. MEASUREMENTS AND MAIN RESULTS: In vitro exposure of AM to PM2.5 did not affect M. tuberculosis phagocytosis. High in vivo-acquired AM PM burden reduced constitutive, M. tuberculosis and PM-induced interleukin-1ß production in freshly isolated BAC but not in autologous PBMC while it reduced constitutive production of tumour necrosis factor-alpha in both BAC and PBMC. Further, PM burden was positively correlated with constitutive, PM, M. tuberculosis and purified protein derivative (PPD)-induced interferon gamma (IFN-γ) in BAC, and negatively correlated with PPD-induced IFN-γ in PBMC. CONCLUSIONS: Inhalation exposure to urban air pollution PM impairs important components of the protective human lung and systemic immune response against M. tuberculosis. PM load in AM is correlated with altered M. tuberculosis-induced cytokine production in the lung and systemic compartments. Chronic PM exposure with high constitutive expression of proinflammatory cytokines results in relative cellular unresponsiveness.

RESUMEN

BACKGROUND: Breast, colorectal, and prostate cancer survivors are at increased risk for late and long-term effects post-treatment. The post-treatment phase of care is often poorly coordinated and survivors navigate follow-up care with minimal information or guidance from their healthcare team. This manuscript describes the Extended Cancer Education for Longer-term Survivors (EXCELS) in Primary Care protocol. EXCELS is a randomized controlled trial to test the efficacy of patient-level self-management educational strategies on adherence to preventative health service use and cancer survivorship follow-up guidelines. METHODS: The EXCELS trial compares four conditions: (1) EXCELS-website (e.g., a mobile-optimized technology platform); (2) EXCELS-health coaching; (3) EXCELS-website and health coaching; and (4) a print booklet. Approximately 480 breast, colorectal, and prostate survivors will be recruited through the New Jersey Primary Care Research Network (NJPCRN) and New Jersey State Cancer Registry (NJSCR). Eligible survivors (diagnosed stages 1-3) must have completed active treatment, access to a phone and a computer, smartphone or tablet with internet access, and be able to speak and read English. Patient assessments occur at baseline, 6, 12, and 18 months. The primary outcomes are increased engagement in preventive health services and monitoring for cancer recurrence and treatment-related late effects. DISCUSSION: The EXCELS trial is the first to test cancer survivorship educational self-management interventions for cancer survivors in a primary care context. Findings from this trial will inform successful implementation and engagement strategies for longer-term, post-treatment cancer survivors managed in primary care settings. TRIAL REGISTRATION: Registered August 1, 2017 at ClinicalTrials.gov , trial # NCT03233555.

RESUMEN

OBJECTIVES: Head and neck cancers (HNCs) may be among the health consequences of involvement in the World Trade Center (WTC) response on and after 11 September 2001. We conducted a nested case-control study of WTC Health Program (WTCHP) general responders to examine the effects of WTC exposures and behavioural risk factors on HNC. METHODS: We enrolled 64 cases and 136 controls, matched on age, sex and race/ethnicity within risk sets. We assessed tobacco and alcohol use, sexual activity, and occupational exposures prior to, during and after WTC exposure until case diagnosis via questionnaire. We obtained WTC exposure information (duration (first to last day), total days and location of work) from the WTCHP General Responder Data Center. We assessed associations with HNC, and interaction among exposures, using conditional logistic regression. RESULTS: Responders in protective services versus other occupations had increased odds (OR: 2.51, 95% CI 1.09 to 5.82) of HNC. Among those in non-protective services occupations, arriving to the WTC effort on versus after 11 September 2001 was significantly associated with HNC (OR: 3.77, 95% CI 1.00 to 14.11). Duration of work was not significantly associated with HNC. Lifetime and post-WTC years of cigarette smoking and post-WTC number of sex partners were positively and significantly associated with HNC, while alcohol consumption was not. CONCLUSIONS: These findings suggest opportunities for HNC risk factor mitigation (eg, smoking cessation, human papillomavirus vaccination) and contribute to a risk factor profile which may assist WTCHP clinicians with identifying high-risk responders and improve detection and treatment outcomes in this population.

RESUMEN

BACKGROUND: Patient activation-the knowledge, skills, and confidence to manage one's health-is associated with improved self-management behaviors for several chronic conditions. This study assesses rates of patient activation in breast and prostate cancer survivors and explores the characteristics associated with patient activation. METHODS: A cross-sectional study of survivors with localized (Stage I or II) breast and prostate cancers who were post-treatment (between 1-10+ years) were recruited from 4 community hospital sites in New Jersey. Survey data on patient characteristics (demographic and psychosocial) and clinical factors were assessed to explore the relationships with patient activation using the Patient Activation Measure-13. RESULTS: Among 325 survivors (112 prostate; 213 breast), overall patient activation was high (M = 3.25). Activation was significantly lower among prostate survivors when compared with breast cancer survivors (M = 3.25 [SD, 0.38] vs M = 3.34 [SD, 0.37], P<.05). For prostate survivors, race (P < .05), marital status (P < .001), employment status (P < .01), household income (P < .05), and fear of recurrence (P < .01) were significantly associated with patient activation. For both groups, ease of access to oncology team and primary care physicians (PCPs) (all P values < .001) and perceptions of time spent with oncologists' team and PCPs (all P values < .01) were positive predictors of activation. CONCLUSIONS: In both breast and prostate survivors, access to providers (both PCPs and oncologists) and perception that adequate time spent with providers were associated with activation. Therefore, clinical interventions maybe a promising avenue to improve patient activation. Research is needed to develop and test tailored patient activation interventions to improve self-management among cancer survivors.

RESUMEN

BACKGROUND: Hurricanes Irene and Sandy heavily impacted New Jersey. Investigating EMS dispatch trends during these storms may allow us to prepare for future disasters. OBJECTIVES: Our objectives to characterize the types of EMS dispatches immediately before, during, and after landfall compared to a control period. METHODS: This retrospective study was conducted at a large EMS dispatch center that provides first responders, Basic Life Support (BLS), Advanced Life Support (ALS), and critical care transport services to an area with approximately 20 receiving hospitals including a Level I Trauma Center. At peak staffing, there are 8-10 ALS vehicles, 25 BLS vehicles, and 3 critical care transport vehicles deployed. We included of the day of landfall and seven days before and after. We compared dispatch data to a control period in 2010 that mirrored Hurricane Sandy the dates of. Descriptive statistics and two way ANOVA were used to assess dispatch, gender and age differences. RESULTS: We found Hurricane Sandy dispatches peaked 2 days after landfall. Both ALS and BLS had an increase in age in the post-Sandy period compared to the pre-Sandy (ALS 58.5 to 64.2, p = 0.005, ANOVA p = 0.078; BLS 47.4 to 56.3, p < 0.001, ANOVA p = 0.001). There were 17 "hurricane related" (loss of power related issues, oxygen supply depleted, evacuation) and 15 carbon monoxide dispatches in the post-Sandy period and none in the others, including peri-Irene. The average age of cardiac arrest dispatches was lower in the post-Irene group compared to pre-Irene (74.3 to 47.8, p = 0.023). There were no critical care requests before or after Hurricane Sandy, but there were 14 around Hurricane Irene and 10 surrounding the control period. CONCLUSIONS: Dispatch data can inform natural disaster planning. Education efforts can focus on geriatric patients, as well as resource distribution planning for an increase in geriatric populations. However, pattern variability between storms shows further study is needed to clarify exactly which resources should be utilized in order to maintain an ideal response to a natural disaster.

RESUMEN

The performances of a portable X-Ray Fluorescence (XRF) lead paint analyzer (RMD LPA-1, Protec Instrument Corp., Waltham, MA) and a commercially available colorimetric lead test kit (First Alert Lead Test Kit, eAccess Solutions, Inc., Palatine, IL) were evaluated for use by local or state health departments as potential cost-effective rapid analysis or "spot test" field techniques for tentative identification of lead content in sindoor powders. For both field-sampling methods, sensitivity, specificity and predictive values varied widely for samples containing <300,000 µg/g lead. For samples containing ≥300,000 µg/g lead, the aforementioned metrics were 100% (however, the CIs had a wide range). In addition, both field sampling methods showed clear, consistent positive readings only for samples containing ≥300,000 µg/g lead. Even samples with lead content as high as 5,110 µg/g were not positively identified by either field analysis technique. The results of this study suggest the XRF analyzer and colorimetric lead test kit cannot be used as a rapid field test for sindoor by health department inspectors.

RESUMEN

PURPOSE: The aim of our study was to determine the incidence and risk factors of dural venous sinus thrombosis and epidural hemorrhage in the setting of a blunt trauma causing a calvarial fracture crossing a dural venous sinus. METHODS: A retrospective review of 472 blunt trauma patients with calvarial fracture crossing a dural venous sinus was performed. Two hundred ten patients who underwent computed tomography venography were identified and evaluated for the presence of dural venous sinus thrombosis and/or epidural hemorrhage. Site and displacement of fractures, as well as age, sex, Glasgow Coma Scale (GCS) score, and mechanism of injury, were considered for potential predictive value of thrombosis and/or epidural hemorrhage. RESULTS: We found a 23% incidence of dural venous sinus thrombosis in patients with a fracture traversing a dural venous sinus. Significant predictors of thrombosis included temporal fracture (38% incidence) and skull base fracture (31% incidence). Occipital fracture not involving the skull base was associated with a significantly decreased risk of thrombosis, with an incidence of 9%. Decreased GCS score and fall from height greater than 10 feet additionally predicted dural venous sinus thrombosis. Significant predictors of epidural hemorrhage included parietal fractures and displaced fractures, although a large percentage of nondisplaced fractures in other bones demonstrated epidural hemorrhage as well. CONCLUSIONS: Dural venous sinus thrombosis in the setting of blunt trauma with a calvarial fracture crossing a dural venous sinus has an incidence of 23%. Increased suspicion for thrombosis is warranted in patients with temporal or skull base fractures, low GCS score, and recent fall from great height.

RESUMEN

Despite the strong link between obesity and cancer development, individuals are less likely to identify obesity as a risk factor for cancer than family history. Family history of cancer has been documented to influence perceived risk of developing cancer, yet it is unclear if excess weight impacts cancer risk perceptions. The purpose of this study was to examine absolute and relative risk perceptions for cancer by weight status. Cross-sectional data were obtained from the National Cancer Institute's 2011 Health Information National Trends Survey (n = 2585). Demographics, anthropometric data, family history of cancer, health behaviors, and absolute and relative cancer risk perceptions were evaluated. The effect of weight and family history on absolute and relative cancer risk perceptions was analyzed through weighted descriptive and logistic regression analyses. 22.8 and 28.6 % of subjects reported that they were very unlikely/unlikely to develop cancer in their lifetime (absolute risk) and when compared to others their age (relative risk), respectively. Findings indicated differences in risk perceptions between those with and without a family history of cancer (p < 0.0001). No significant differences were found between BMI categories for absolute cancer risk perceptions despite stratification by family history. Obese subjects were more likely to have an increased relative risk perception of cancer compared to healthy weight subjects (p = 0.0066); this association remained significant when stratified by family history (p = 0.0161). Educating individuals, especially those who are overweight/obese, about the impact of excess weight on cancer risk may improve risk accuracy and promote cancer risk reduction through weight management.

RESUMEN

OBJECTIVE: The study aim was to test the acceptability and preliminary efficacy of a novel interactive web-based breast reconstruction decision support aid (BRAID) for newly diagnosed breast cancer patients considering mastectomy. METHODS: Fifty-five women considering mastectomy were randomly assigned to receive the BRAID versus the Cancer Support Community's Frankly Speaking About Cancer: Breast Reconstruction pamphlet. Participants completed measures of breast reconstruction (BR) knowledge, preparation to make a decision, decisional conflict, anxiety, and BR intentions before randomization and 2 weeks later. RESULTS: In terms of acceptability, enrollment into the study was satisfactory, but the rate of return for follow-up surveys was lower among BRAID participants than pamphlet participants. Both interventions were evaluated favorably in terms of their value in facilitating the BR decision, and the majority of participants completing the follow-up reported viewing the materials. In terms of preliminary efficacy, both interventions resulted in significant increases in BR knowledge and completeness and satisfaction with preparation to make a BR decision, and both interventions resulted in a significant reduction in decision conflict. However, there were no differences between interventions. CONCLUSION: A widely available free pamphlet and a web-based customized decision aid were highly utilized. The pamphlet was as effective in educating women about BR and prepared women equally as well to make the BR decision as compared with a more costly, customized web-based decision support aid.

RESUMEN

PURPOSE: This substudy of an intervention trial aimed to describe barriers to participation in psychological care among primary caregivers of children who were about to undergo a hematopoietic stem cell transplantation (HSCT), including demographic and medical correlates. METHOD: Three hundred and twelve primary caregivers of children undergoing HSCT who were approached to participate in a psychological intervention trial (n = 218 enrollees and 94 decliners) completed a measure of barriers to psychological care. RESULTS: The most frequently endorsed barriers to care were focusing on the child as priority, not wanting to leave the child's bedside, and already having adequate psychosocial support. The least frequently endorsed barriers were location, wait times, and stigma around seeking psychological care. CONCLUSIONS: Results suggest that explaining how psychological care for a primary caregiver can positively affect their ill child may reduce barriers to seeking needed support services. Certain practical barriers to care may be irrelevant in inpatient settings where psychological support is offered.

RESUMEN

Commuting in automobiles can contribute substantially to total traffic-related air pollution (TRAP) exposure, yet measuring commuting exposures for studies of health outcomes remains challenging. To estimate real-world TRAP exposures, we developed and evaluated the robustness of a scripted drive protocol on the NJ Turnpike and local roads between April 2007 and October 2014. Study participants were driven in a car with closed windows and open vents during morning rush hours on 190 days. Real-time measurements of PM2.5, PNC, CO, and BC, and integrated samples of NO2, were made in the car cabin. Exposure measures included in-vehicle concentrations on the NJ Turnpike and local roads and the differences and ratios of these concentrations. Median in-cabin concentrations were 11 µg/m3 PM2.5, 40 000 particles/cm3, 0.3 ppm CO, 4 µg/m3 BC, and 20.6 ppb NO2. In-cabin concentrations on the NJ Turnpike were higher than in-cabin concentrations on local roads by a factor of 1.4 for PM2.5, 3.5 for PNC, 1.0 for CO, and 4 for BC. Median concentrations of NO2 for full rides were 2.4 times higher than ambient concentrations. Results were generally robust relative to season, traffic congestion, ventilation setting, and study year, except for PNC and PM2.5, which had secular and seasonal trends. Ratios of concentrations were more stable than differences or absolute concentrations. Scripted drives can be used for generating reasonably consistent in-cabin increments of exposure to traffic-related air pollution.
