Understanding male circumcision: insights from a peri-urban community in Maputo City, Mozambique
Baduro J , McCabe KC , Cavele N , José A , Mulimela A , Jamnadas M , Manhiça C , Monjane C , Nhachungue S , Decroo T , Macicame I . Int Health 2024 BACKGROUND: Circumcision is a protective measure against sexually transmitted infections (STIs), reducing the risk of HIV infection. This study reported coverage of male circumcision and assessed the factors associated with male uncircumcision in a peri-urban area in Maputo City, Mozambique. METHODS: This cross-sectional study of the Health Demographic Surveillance System in the Polana Caniço neighborhood investigated the sociodemographic and behavioral factors associated with uncircumcised males aged 15-49 y from October 2019 to June 2021. Data were collected from an HIV risk factors questionnaire and descriptive analyses conducted comparing self-reported male circumcision status by sociodemographic factors and sexual behaviors. The association was assessed via χ2 tests, and a multivariable logistic regression model was constructed. Adjusted ORs and 95% CIs were reported for factors associated with uncircumcised status. RESULTS: Of the 3481 males aged 15-49 y who responded to the questionnaire, 79.5% (2766) self-reported being circumcised. The percentage of uncircumcised men steadily increased with age, ranging from 12.4% (95) among males aged 15-19 y to 34.5% (148) of men aged 40-49 y. Men without education or with primary education, as well as those not practicing Islam, were 3-4 times more likely to be uncircumcised. Uncircumcised men were more likely to self-report an STI and a lack of condom use. CONCLUSIONS: Being uncircumcised was associated with not using condoms and having STIs, highlighting the need to further emphasize combination HIV-prevention programs and regular HIV/STI screening. Targeting males with lower education and across religions can help reach those with lower coverage of this effective prevention intervention. |
The National Cancer Database conforms to the standardized framework for registry and data quality
Palis BE , Janczewski LM , Browner AE , Cotler J , Nogueira L , Richardson LC , Benard V , Wilson RJ , Walker N , McCabe RM , Boffa DJ , Nelson H . Ann Surg Oncol 2024 BACKGROUND: Standardization of procedures for data abstraction by cancer registries is fundamental for cancer surveillance, clinical and policy decision-making, hospital benchmarking, and research efforts. The objective of the current study was to evaluate adherence to the four components (completeness, comparability, timeliness, and validity) defined by Bray and Parkin that determine registries' ability to carry out these activities to the hospital-based National Cancer Database (NCDB). METHODS: Tbis study used data from U.S. Cancer Statistics, the official federal cancer statistics and joint effort between the Centers for Disease Control and Prevention (CDC) and the National Cancer Institute (NCI), which includes data from National Program of Cancer Registries (NPCR) and Surveillance, Epidemiology, and End Results (SEER) to evaluate NCDB completeness between 2016 and 2020. The study evaluated comparability of case identification and coding procedures. It used Commission on Cancer (CoC) standards from 2022 to assess timeliness and validity. RESULTS: Completeness was demonstrated with a total of 6,828,507 cases identified within the NCDB, representing 73.7% of all cancer cases nationwide. Comparability was followed using standardized and international guidelines on coding and classification procedures. For timeliness, hospital compliance with timely data submission was 92.7%. Validity criteria for re-abstracting, recording, and reliability procedures across hospitals demonstrated 94.2% compliance. Additionally, data validity was shown by a 99.1% compliance with histologic verification standards, a 93.6% assessment of pathologic synoptic reporting, and a 99.1% internal consistency of staff credentials. CONCLUSION: The NCDB is characterized by a high level of case completeness and comparability with uniform standards for data collection, and by hospitals with high compliance, timely data submission, and high rates of compliance with validity standards for registry and data quality evaluation. |
COVID-19 Stats: COVID-19 Incidence,* by Urban-Rural Classification
Duca LM , Coyle J , McCabe C , McLean CA . MMWR Morb Mortal Wkly Rep 2020 69 (46) 1753 Early in the pandemic, from mid-March to mid-May, COVID-19 incidence was highest among residents of large central and large fringe metropolitan areas. Beginning in mid-April, incidence in large metropolitan (central and fringe) areas declined and then increased similarly among all urban-rural areas. In September 2020, COVID-19 incidence sharply increased, and it remains highest among residents of medium/small metropolitan areas and micropolitan/noncore areas, indicating increased spread into rural communities. In October, weekly incidence was increasing steadily among all urban-rural areas. |
Trends in the Use of Telehealth During the Emergence of the COVID-19 Pandemic - United States, January-March 2020.
Koonin LM , Hoots B , Tsang CA , Leroy Z , Farris K , Jolly T , Antall P , McCabe B , Zelis CBR , Tong I , Harris AM . MMWR Morb Mortal Wkly Rep 2020 69 (43) 1595-1599 In February 2020, CDC issued guidance advising persons and health care providers in areas affected by the coronavirus disease 2019 (COVID-19) pandemic to adopt social distancing practices, specifically recommending that health care facilities and providers offer clinical services through virtual means such as telehealth.* Telehealth is the use of two-way telecommunications technologies to provide clinical health care through a variety of remote methods.(†) To examine changes in the frequency of use of telehealth services during the early pandemic period, CDC analyzed deidentified encounter (i.e., visit) data from four of the largest U.S. telehealth providers that offer services in all states.(§) Trends in telehealth encounters during January-March 2020 (surveillance weeks 1-13) were compared with encounters occurring during the same weeks in 2019. During the first quarter of 2020, the number of telehealth visits increased by 50%, compared with the same period in 2019, with a 154% increase in visits noted in surveillance week 13 in 2020, compared with the same period in 2019. During January-March 2020, most encounters were from patients seeking care for conditions other than COVID-19. However, the proportion of COVID-19-related encounters significantly increased (from 5.5% to 16.2%; p<0.05) during the last 3 weeks of March 2020 (surveillance weeks 11-13). This marked shift in practice patterns has implications for immediate response efforts and longer-term population health. Continuing telehealth policy changes and regulatory waivers might provide increased access to acute, chronic, primary, and specialty care during and after the pandemic. |

Clin Infect Dis 2022 76 (3) e1320-e1327 BACKGROUND: Cache Valley virus (CVV) is a mosquito-borne virus that is a rare cause of disease in humans. In the Fall of 2020, a patient developed encephalitis six weeks following kidney transplantation and receipt of multiple blood transfusions. METHODS: After ruling out more common etiologies, metagenomic next-generation sequencing (mNGS) of cerebrospinal fluid (CSF) was performed. We reviewed the medical histories of the index kidney recipient, organ donor, and recipients of other organs from the same donor and conducted a blood traceback investigation to evaluate blood transfusion as a possible source of infection in the kidney recipient. We tested patient specimens by reverse transcription-polymerase chain reaction (RT-PCR), plaque reduction neutralization test (PRNT), cell culture, and whole genome sequencing. RESULTS: CVV was detected in CSF from the index patient by mNGS, and this result was confirmed by RT-PCR, viral culture, and additional whole genome sequencing. The organ donor and other organ recipients had no evidence of infection with CVV by molecular or serologic testing. Neutralizing antibodies against CVV were detected in serum from a donor of red blood cells received by the index patient immediately prior to transplant. CVV neutralizing antibodies were also detected in serum from a patient who received the co-component plasma from the same blood donation. CONCLUSION: Our investigation demonstrates probable CVV transmission through blood transfusion. Clinicians should consider arboviral infections in unexplained meningoencephalitis after blood transfusion or organ transplantation. The use of mNGS testing might facilitate detection of rare, unexpected infections, particularly in immunocompromised patients. |
Change in condom use in populations newly aware of HIV diagnosis in the United States and Canada: A systematic review and meta-analysis
Malekinejad M , Blodgett J , Horvath H , Parriott A , Hutchinson AB , Shrestha RK , McCabe D , Volberding P , Kahn JG . AIDS Behav 2021 25 (6) 1839-1855 HIV-infected individuals "aware" of their infection are more likely to use condoms, compared to HIV-infected "unaware" persons. To quantify this likelihood, we undertook a systematic review and meta-analysis of U.S. and Canadian studies. Twenty-one eligible studies included men who have sex with men (MSM; k = 15), persons who inject drugs (PWID; k = 2), and mixed populations of high-risk heterosexuals (HRH; k = 4). Risk ratios (RR) of "not always using condoms" with partners of any serostatus were lower among aware MSM (RR 0.44 [not significant]), PWID (RR 0.70) and HRH (RR 0.27); and, in aware MSM, with partners of HIV-uninfected or unknown status (RR 0.46). Aware individuals had lower "condomless sex likelihood" with HIV-uninfected or unknown status partners (MSM: RR 0.58; male PWID: RR 0.44; female PWID: RR 0.65; HRH: RR 0.35) and with partners of any serostatus (MSM only, RR 0.72). The association diminished over time. High risk of bias compromised evidence quality. |
Potential contributions of clinical and community testing in identifying persons with undiagnosed HIV infection in the United States
Kahn JG , Bendavid E , Dietz PM , Hutchinson A , Horvath H , McCabe D , Wolitski RJ . J Int Assoc Provid AIDS Care 2020 19 2325958220950902 BACKGROUND: An estimated 166,155 individuals in the United States have undiagnosed HIV infection. We modeled the numbers of HIV-infected individuals who could be diagnosed in clinical and community settings by broadly implementing HIV screening guidelines. SETTING: United States. METHODS: We modeled testing for general population (once lifetime) and high-risk populations (annual): men who have sex with men, people who inject drugs, and high-risk heterosexuals. We used published data on HIV infections, HIV testing, engagement in clinical care, and risk status disclosure. RESULTS: In clinical settings, about 76 million never-tested low-risk and 2.6 million high-risk individuals would be tested, yielding 36,000 and 55,000 HIV diagnoses, respectively. In community settings, 30 million low-risk and 4.4 million high-risk individuals would be tested, yielding 75,000 HIV diagnoses. CONCLUSION: HIV testing in clinical and community settings diagnoses similar numbers of individuals. Lifetime and risk-based testing are both needed to substantially reduce undiagnosed HIV. |
Outlook for tuberculosis elimination in California: An individual-based stochastic model
Goodell AJ , Shete PB , Vreman R , McCabe D , Porco TC , Barry PM , Flood J , Marks SM , Hill A , Cattamanchi A , Kahn JG . PLoS One 2019 14 (4) e0214532 RATIONALE: As part of the End TB Strategy, the World Health Organization calls for low-tuberculosis (TB) incidence settings to achieve pre-elimination (<10 cases per million) and elimination (<1 case per million) by 2035 and 2050, respectively. These targets require testing and treatment for latent tuberculosis infection (LTBI). OBJECTIVES: To estimate the ability and costs of testing and treatment for LTBI to reach pre-elimination and elimination targets in California. METHODS: We created an individual-based epidemic model of TB, calibrated to historical cases. We evaluated the effects of increased testing (QuantiFERON-TB Gold) and treatment (three months of isoniazid and rifapentine). We analyzed four test and treat targeting strategies: (1) individuals with medical risk factors (MRF), (2) non-USB, (3) both non-USB and MRF, and (4) all Californians. For each strategy, we estimated the effects of increasing test and treat by a factor of 2, 4, or 10 from the base case. We estimated the number of TB cases occurring and prevented, and net and incremental costs from 2017 to 2065 in 2015 U.S. dollars. Efficacy, costs, adverse events, and treatment dropout were estimated from published data. We estimated the cost per case averted and per quality-adjusted life year (QALY) gained. MEASUREMENTS AND MAIN RESULTS: In the base case, 106,000 TB cases are predicted to 2065. Pre-elimination was achieved by 2065 in three scenarios: a 10-fold increase in the non-USB and persons with MRF (by 2052), and 4- or 10-fold increase in all Californians (by 2058 and 2035, respectively). TB elimination was not achieved by any intervention scenario. The most aggressive strategy, 10-fold in all Californians, achieved a case rate of 8 (95% UI 4-16) per million by 2050. Of scenarios that reached pre-elimination, the incremental net cost was $20 billion (non-USB and MRF) to $48 billion. These had an incremental cost per QALY of $657,000 to $3.1 million. A more efficient but somewhat less effective single-lifetime test strategy reached as low as $80,000 per QALY. CONCLUSIONS: Substantial gains can be made in TB control in coming years by scaling-up current testing and treatment in non-USB and those with medical risks. |
Cost-effectiveness of hepatitis B virus infection screening and treatment or vaccination in 6 high-risk populations in the United States
Chahal HS , Peters MG , Harris AM , McCabe D , Volberding P , Kahn JG . Open Forum Infect Dis 2019 6 (1) ofy353 Background. Two million individuals with chronic hepatitis B (CHB) in the United States are at risk for premature death due to liver cancer and cirrhosis. CHB can be prevented by vaccination and controlled with treatment. Methods. We created a lifetime Markov model to estimate the cost-effectiveness of strategies to prevent or treat CHB in 6 highrisk populations: foreign-born Asian/Pacific Islanders (API), Africa-born blacks (AbB), incarcerated, refugees, persons who inject drugs (PWID), and men who have sex with men (MSM). We studied 3 strategies: (a) screen for HBV infection and treat infected ("treatment only"), (b) screen for HBV susceptibility and vaccinate susceptible ("vaccination only"), and (c) screen for both and follow-up appropriately ("inclusive"). Outcomes were expressed in incremental cost-effectiveness ratios (ICERs), clinical outcomes, and new infections. Results. Vaccination-only and treatment-only strategies had ICERs of $6000-$21 000 per quality-adjusted life-year (QALY) gained, respectively. The inclusive strategy added minimal cost with substantial clinical benefit, with the following costs per QALY gained vs no intervention: incarcerated $3203, PWID $8514, MSM $10 954, AbB $17 089, refugees $17 432, and API $18 009. Clinical complications dropped in the short/intermediate (1%-25%) and long (0.4%-16%) term. Findings were sensitive to age, discount rate, health state utility in immune or susceptible stages, progression rate to cirrhosis or inactive disease, and tenofovir cost. The probability of an inclusive program costing <$50 000 per QALY gained varied between 61% and 97% by population. Conclusions. An inclusive strategy to screen and treat or vaccinate is cost-effective in reducing the burden of hepatitis B virus among all 6 high-risk, high-prevalence populations. |
(1 3) beta-Glucan induces multimodal toxicity responses in parallel exposures of model human lung epithelial cells and immature macrophage
Turner J , McCabe K , Snawder J , Hernandez M . Air Qual Atmos Health 2018 12 (4) 379-387 Many epidemiological studies have associated bioaerosol exposures with a variety of adverse health effects; however, the role of bioaerosol components in the development and manifestation of hypersensitivity and non-infectious respiratory diseases remains unclear. Despite many studies which have examined allergic responses to bioaerosols, less is known about non-allergenic effects. In order to elucidate the mechanisms by which bioaerosols can exert non-atopic stresses on a cellular level, there is a need for improving existing in vitro approaches. In response, a cohort of toxicology assays were optimized to create a robust analytical suite for studying the effects that biogenic atmospheric pollutants generate on two model human lung cell lines (A549 epithelial line and GDM-1 immature macrophage line). To demonstrate the utility for studying the cellular responses to select bioaerosols, cells exposed to curdlan (a linear (1 3)--glucan) were examined in a composite cytometry platform. Results suggest that curdlan has the potential to elicit significant responses in A549 and GDM-1 in two or more toxicological modes associated with exposure to airborne particulate matter. As designed, this suite provided a more powerful tool for characterizing curdlan-induced toxicological potential than any individual assay. Responses to curdlan were distinctly modal and cell line dependent, suggesting that the use of a suite of toxicological assays, in a common platform on different cell lines, can help provide important insights into the formative toxigenic responses that primary bioaerosols can induce in respiratory cells. |
Long-term survivorship care after cancer treatment - summary of a 2017 National Cancer Policy Forum Workshop
Kline RM , Arora NK , Bradley CJ , Brauer ER , Graves DL , Lunsford NB , McCabe MS , Nasso SF , Nekhlyudov L , Rowland JH , Schear RM , Ganz PA . J Natl Cancer Inst 2018 110 (12) 1300-1310 The National Cancer Policy Forum of the National Academies of Sciences, Engineering and Medicine sponsored a workshop on July 24 and 25, 2017 on Long-Term Survivorship after Cancer Treatment. The workshop brought together diverse stakeholders (patients, advocates, academicians, clinicians, research funders, and policymakers) to review progress and ongoing challenges since the Institute of Medicine (IOM)'s seminal report on the subject of adult cancer survivors published in 2006. This commentary profiles the content of the meeting sessions and concludes with recommendations that stem from the workshop discussions. Although there has been progress over the past decade, many of the recommendations from the 2006 report have not been fully implemented. Obstacles related to the routine delivery of standardized physical and psychosocial care services to cancer survivors are substantial, with important gaps in care for patients and caregivers. Innovative care models for cancer survivors have emerged, and changes in accreditation requirements such as the Commission on Cancer's (CoC) requirement for survivorship care planning have put cancer survivorship on the radar. The Center for Medicare & Medicaid Innovation's Oncology Care Model (OCM), which requires psychosocial services and the creation of survivorship care plans for its beneficiary participants, has placed increased emphasis on this service. The OCM, in conjunction with the CoC requirement, is encouraging electronic health record vendors to incorporate survivorship care planning functionality into updated versions of their products. As new models of care emerge, coordination and communication among survivors and their clinicians will be required to implement patient- and community-centered strategies. |
CDC Grand Rounds: Addressing health disparities in early childhood
Robinson LR , Bitsko RH , Thompson RA , Dworkin PH , McCabe MA , Peacock G , Thorpe PG . MMWR Morb Mortal Wkly Rep 2017 66 (29) 769-772 Research suggests that many disparities in overall health and well-being are rooted in early childhood (1,2). Stressors in early childhood can disrupt neurologic, metabolic, and immunologic systems, leading to poorer developmental outcomes (1). However, consistent, responsive caregiving relationships and supportive community and health care environments promote an optimal trajectory (3,4). The first 8 years of a child's life build a foundation for future health and life success (5-7). Thus, the cumulative and lifelong impact of early experiences, both positive and negative, on a child's development can be profound. Although the health, social service, and education systems that serve young children and their families and communities provide opportunities to support responsive relationships and environments, efforts by these systems are often fragmented because of restrictions that limit the age groups they can serve and types of services they can provide. Integrating relationship-based prevention and intervention services for children early in life, when the brain is developing most rapidly, can optimize developmental trajectories (4,7). By promoting collaboration and data-driven intervention activities, public health can play a critical role in both the identification of at-risk children and the integration of systems that can support healthy development. These efforts can address disparities by reducing barriers that might prevent children from reaching their full potential. |
Alcohol and cocaine use among Latino and African American MSM in 6 US cities
Zaller N , Yang C , Operario D , Latkin C , McKirnan D , O'Donnell L , Fernandez M , Seal D , Koblin B , Flores S , Spikes P . J Subst Abuse Treat 2017 80 26-32 Gay, bisexual, and other men who have sex with men (MSM) are disproportionately affected by HIV. MSM comprise roughly 2% of the US population, yet approximately two-thirds of new HIV infections are among MSM (Centers for Disease Control and Prevention, 2016). Additionally, significant racial and ethnic disparities exist with respect to HIV transmission among MSM. Based on the current HIV diagnoses rates in the US, about 1 in 2 African American men who have sex with men (AAMSM), 1 in 4 Latino MSM (LMSM) and 1 in 11 white MSM will be diagnosed with HIV during their lifetime (Center for Disease Control and Prevention (CDC), 2016a). In general, substance-using MSM are among the groups with the greatest risk for HIV infection (Centers for Disease Control and Prevention, 2011; Margolis, Joseph, Hirshfield, et al., 2014; Pines, Gorbach, Weiss, et al., 2014; Plankey, Ostrow, Stall, et al., 2007); nearly a third of incident HIV infections among MSM may be associated with non-injection drug use (Mansergh et al., 2008; Van Tieu & Koblin, 2009). Substance-using sexual minorities are more likely to underutilize substance use treatment (McCabe, Bostwick, Hughes, West, & Boyd, 2010) and may be an HIV transmission bridge to non-drug-using populations (Lambert et al., 2011). | With respect to alcohol use, high rates of both alcohol consumption and binge drinking have been documented among MSM populations (Finlayson et al., 2011). Additionally, previous studies have found associations between heavy drinking, as define as having 6 or more drinks on one occasion or 4 or more drinks daily, and HIV risk behaviors among MSM, such as condomless anal intercourse and greater number of sexual patterns (Colfax et al., 2004; Greenwood et al., 2001; Koblin et al., 2003a; Woolf & Maisto, 2009). Previous studies also suggest that many substance-using MSM populations engage in use of multiple substances, often concomitantly (Santos et al., 2013). There also may be a dose response with number and frequency of substances used with respect to condomless anal sex among HIV negative MSM (Santos et al., 2013). However, patterns of substance-use vary across racial and ethnic MSM populations, e.g. African American substance-using MSM being more likely to use crack/cocaine relative to other substance-using MSM populations (Goldstein, Burstyn, LeVasseur, & Welles, 2016; Halkitis & Jerome, 2008; Hatfield, Horvath, Jacoby, & Simon Rosser, 2009; Mimiaga, Reisner, Fontaine, et al., 2010; Paul, Boylan, Gregorich, Ayala, & Choi, 2014). Thus, it is important to better understand patterns of concomitant substance-use, e.g. methamphetamine, crack/cocaine and alcohol, across specific sociodemographic categories among MSM populations (Santos et al., 2013). Sociodemographic characteristics which may be particularly relevant for specific MSM populations include poverty and history of incarceration. For example, pronounced racial disparities have been found between AAMSM and other MSM populations with respect to structural barriers, such as low income, unemployment and incarceration, associated with HIV infection (Millet, Peterson, Flores, Hart, et al., 2012). Additionally, a recent study conducted by Rutledge et al, found a high proportion of MSM reporting both a history of incarceration and substance use. This study found rates of incarceration highest among men who classified themselves as “down-low”, e.g. endorsing secrecy about same-sex sexual behavior, promting the authors to posit that this population may engage in trading sex for money more often and thus increase their risk for incarceration (Rutledge, Jemmott, O'Leary, & Icard, 2016). |
Correspondence of folate dietary intake and biomarker data
Bailey RL , Fulgoni VL , Taylor CL , Pfeiffer CM , Thuppal SV , McCabe GP , Yetley EA . Am J Clin Nutr 2017 105 (6) 1336-1343 Background: Public health concerns with regard to both low and high folate status exist in the United States. Recent publications have questioned the utility of self-reported dietary intake data in research and monitoring. Objectives: The purpose of this analysis was to examine the relation between self-reported folate intakes and folate status biomarkers and to evaluate their usefulness for several types of applications. Design: We examined usual dietary intakes of folate by using the National Cancer Institute method to adjust two 24-h dietary recalls (including dietary supplements) for within-person variation and then compared these intakes with serum and red blood cell (RBC) folate among 4878 men and nonpregnant, nonlactating women aged ≥19 y in NHANES 2011-2012, a nationally representative, cross-sectional survey, with respect to consistency across prevalence estimates and rank order comparisons.Results: There was a very low prevalence (<1%) of folate deficiency when serum (<7 nmol/L) and RBC (<305 nmol/L) folate were considered, whereas a higher proportion of the population reported inadequate total dietary folate intakes (6%). Similar patterns of change occurred between intakes and biomarkers of folate status when distributions were examined (i.e., dose response), particularly when diet was expressed in mug. Intakes greater than the Tolerable Upper Intake Level greatly increased the odds of having high serum folate (OR: 17.6; 95% CI: 5.5, 56.0). Conclusions: When assessing folate status in the United States, where fortification and supplement use are common, similar patterns in the distributions of diet and biomarkers suggest that these 2 types of status indicators reflect the same underlying folate status; however, the higher prevalence estimates for inadequate intakes compared with biomarkers suggest, among other factors, a systematic underestimation bias in intake data. Caution is needed in the use of dietary folate data to estimate the prevalence of inadequacy among population groups. The use of dietary data for rank order comparisons or to estimate the potential for dietary excess is likely more reliable. |
Utility of population-based birth defects surveillance for monitoring the health of infants and as a foundation for etiologic research
Moore CA , McCabe ER . Birth Defects Res A Clin Mol Teratol 2015 103 (11) 895-8 The National Birth Defects Prevention Network (NBDPN) is a nonprofit volunteer organization in the United States for individuals working on birth defects surveillance, research, and prevention (www.nbdpn.org) including, among others, public health officials, epidemiologists, clinicians, and parent advocates. NBDPN works to improve the quality of birth defects surveillance data, and to make these data more accessible both in publications and online. NBDPN also works to increase collaboration among surveillance programs and advance our understanding of the causes and risk factors for birth defects. In this year’s annual report from the NBDPN, 40 programs reported updated birth defects surveillance data on at least some of the 47 defects monitored by this organization. |
A toxicology suite adapted for comparing parallel toxicity responses of model human lung cells to diesel exhaust particles and their extracts
Turner J , Hernandez M , Snawder JE , Handorean A , McCabe KM . Aerosol Sci Technol 2015 49 (8) 599-610 Epidemiological studies have shown that exposure to airborne particulate matter (PM) can be an important risk factor for some common respiratory diseases. While many studies have shown that PM exposures are associated with inflammatory reactions, the role of specific cellular responses in the manifestation of primary hypersensitivities and the progression of respiratory diseases remains unclear. In order to better understand mechanisms by which PM can exert adverse health effects, more robust approaches to support in vitro studies are warranted. In response to this need, a group of accepted toxicology assays was adapted to create an analytical suite for screening and evaluating the effects of important, ubiquitous atmospheric pollutants on two model human lung cell lines (epithelial and immature macrophage). To demonstrate the utility of this suite, responses to intact diesel exhaust particles (DEP) and mass-based equivalent doses of their organic extracts were examined. Results suggest that extracts have the potential to induce greater biological responses than those associated with their colloidal counterpart. Additionally, macrophage cells appear to be more susceptible to the cytotoxic effects of both intact DEP and their organic extract, than epithelial cells tested in parallel. As designed, the suite provided a more robust basis for characterizing toxicity mechanisms than the analysis of any individual assay. Findings suggest that cellular responses to PM are cell line dependent, and show that the collection and preparation of PM and/or their extracts have the potential to impact cellular responses relevant to screening fundamental elements of respiratory toxicity. |
Positioning a public health framework at the intersection of child maltreatment and intimate partner violence: primary prevention requires working outside existing systems
Herrenkohl TI , Higgins DJ , Merrick MT , Leeb RT . Child Abuse Negl 2015 48 22-8 Since about the mid-1990s, researchers have been examining the intersection of child maltreatment (CM; also referred to as child abuse and neglect) and children’s exposure to intimate partner violence (IPV; also called domestic violence or DV). Both CM and IPV are major public health concerns that, together, affect a countless number of lives each year in the United States and in other countries around the world. Not only does each form of adversity carry long-term health and psychosocial consequences for those involved, there is increasing evidence of their tendency to cooccur within families. Reviews of research by Todd Herrenkohl and colleagues in 2008 and Daryl Higgins and Marita McCabe in 2001 came to that very conclusion, while underscoring that risk factors like poverty and parental unemployment, parenting stress, social isolation, and drug and alcohol abuse are also present in many cases. For some families with children, community violence and neighborhood social and structural factors add even more stress and trauma into their daily lives. | There is now a sizeable body of research on “adverse childhood experiences,” or “ACEs,” which include CM and IPV. Studies of ACEs have consistently shown a robust, additive effect of these early forms of risk on adult outcomes that include heart and lung disease, diabetes, and certain forms of cancer. Not surprisingly, individuals with more ACEs tend to be the most vulnerable to the early-onset of disease and serious illness. And, studies have shown that adults with this profile can die up to two decades earlier than others with less adversity early on. Twenty-eight states and the District of Columbia now collect data on ACEs using public health surveillance surveys that are part of the Behavioral Risk Factor Surveillance System (BRFSS). Using these data, states are beginning to investigate how ACEs affect life opportunities for their citizens, based on educational attainment, employment, and earnings. |

Approximately 70 attendees and organizers from various advocacy groups, federal agencies (Centers for Disease Control and Prevention, and various NIH Institutes, Centers, and Offices), members of industry, clinicians, and researchers from various academic institutions were greeted by Drs. Yvonne Maddox, Deputy Director of NICHD, and Edward McCabe, Executive Director of the Linda Crnic Institute for Down Syndrome. They charged the participants to focus on the separate issues of contact registries, research databases, and biobanks through both podium presentations and breakout session discussions. Among the breakout groups for each of the major sessions, participants were asked to generate responses to questions posed by the organizers concerning these three research resources as they related to Down syndrome and then to report back to the group at large with a summary of their discussions. This report represents a synthesis of the discussions and suggested approaches formulated by the group as a whole. |
