A comprehensive description of kidney disease progression after acute kidney injury from a prospective, parallel-group cohort study.

Acute kidney injury (AKI) is associated with adverse long-term outcomes, but many studies are retrospective, focused on specific patient groups or lack adequate comparators. The ARID (AKI Risk in Derby) Study was a five-year prospective parallel-group cohort study to examine this. Hospitalized cohorts with and without exposure to AKI were matched 1:1 for age, baseline kidney function, and diabetes. Estimated glomerular filtration rate (eGFR) and the urinary albumin:creatinine ratio (uACR) were measured at three-months, one-, three- and five-years. Outcomes included kidney disease progression, heart failure episodes and mortality. In 866 matched individuals, kidney disease progression at five years was found to be significantly increased in 30% of the exposed group versus 7% of those non-exposed (adjusted odds ratio 2.49 [95% confidence interval 1.43 to 4.36]). In the AKI group, this was largely characterized by incomplete recovery of kidney function by three months. Further episodes of AKI during follow-up were significantly more common in the exposed group (odds ratio 2.71 [1.94 to 3.77]) and had an additive effect on risk of kidney disease progression. Mortality and heart failure episodes were more frequent in the exposed group, but the association with AKI was no longer significant when models were adjusted for three-month eGFR and uACR. In a general hospitalized population, kidney disease progression after five years was common and strongly associated with AKI. Thus, the time course of changes and the attenuation of associations with adverse outcomes after adjustment for three-month eGFR and uACR suggest non-recovery of kidney function is an important assessment in post-AKI care and a potential future target for intervention.

Qualitative Purpose Profiles of Chinese Student Teachers.

Teachers are well positioned to help students cultivate their purpose in life, which is an asset that is associated with optimal development. Teachers must also have a grasp on their own sense of purpose, especially during times of intense social pressure and change, when the capability to sustain and support worthy aims may impart personal resilience and contribute to the social good. To train educators who have this capability, it is therefore vital for teacher education programs to in turn understand their own students' individualized purpose statuses. Using a qualitative person-centered approach, the current study identified purpose profiles of teacher education candidates in China as part of a larger multinational study. Three hundred and thirty-one participants wrote answers to questions about the content and fulfillment of their purpose in life, and statements were reliably coded for how specifically the respondents referenced their purpose, and for whether their purpose aimed to benefit others. A consensual qualitative research approach then identified four purpose profiles: beyond-the-self purpose, self-oriented life goal, daydreamer and purposeless. The meaning of these profiles and their significance for cultivating purpose among China's teachers are discussed.

Fostering mature purpose beyond the classroom: considering family and other institutions in agentic purpose commitment / Promovendo projetos de vida maduros além da sala de aula: o papel da família e de outras instituições no compromisso com um projeto de vida agente

This article addresses two questions about purpose in life: what is mature purpose, and how can it be cultivated? We first outline a picture of mature purpose based in part on established purpose research, and point out new frameworks that can resolve missing pieces and tensions in the current paradigms. We contend that above and beyond fulfilling discrete criteria present in operational definitions, mature purpose requires agentic yet flexible commitment to worthy goals rather than simplistic adoption of expected goals. A review of purpose formation beyond the classroom identifies similar roles of parents, post-secondary educational institutions, and extracurricular activities for supporting development of mature purpose in the direction of agentic commitment, namely, encouraging processes of: active exploration, tentative commitment, and support in navigating and sustaining meaningful commitment.

Este artigo aborda duas questões sobre projetos de vida: o que são projetos de vida e como podem ser cultivados? Primeiramente, esboçamos um quadro de projetos de vida maduro baseado em parte na pesquisa de projetos de vida estabelecida e apontamos novas estruturas que podem resolver as peças que faltam e as tensões nos paradigmas atuais. Afirmamos que, acima e além de cumprir critérios discretos presentes nas definições operacionais, projetos de vida maduros requerem um comprometimento agente, porém flexível, com metas dignas, em vez da adoção simplista de metas esperadas. Uma revisão da formação de projetos de vida além da sala de aula identifica papéis semelhantes de pais, universidades e atividades extracurriculares para apoiar o desenvolvimento de projetos de vida maduros na direção do compromisso agente, a saber, processos de incentivo de: exploração ativa, compromisso experimental e apoio em navegar e manter um compromisso significativo.

Low-dose radiation treatment enhances systemic antitumor immune responses by overcoming the inhibitory stroma.

BACKGROUND: Despite some successes with checkpoint inhibitors for treating cancer, most patients remain refractory to treatment, possibly due to the inhibitory nature of the tumor stroma that impedes the function and entry of effector cells. We devised a new technique of combining immunotherapy with radiotherapy (XRT), more specifically low-dose XRT, to overcome the stroma and maximize systemic outcomes. METHODS: We bilaterally established 344SQ lung adenocarcinoma tumors in 129Sv/Ev mice. Primary and secondary tumors were irradiated with either high-dose or low-dose of XRT with systemic anti-programmed cell death protein 1 and anti-cytotoxic T-lymphocyte associated protein 4 administration. Survival and tumor growth were monitored for the various groups, and secondary tumors were phenotyped by flow cytometry for immune populations. Tumor growth factor-beta (TGF-ß) cytokine levels were assessed locally after low-dose XRT, and specific immune-cell depletion experiments were conducted to identify the major contributors to the observed systemic antitumor effect. RESULTS: Through our preclinical and clinical studies, we observed that when tumor burden was high, there was a necessity of combining high-dose XRT to 'prime' T cells at the primary tumor site, with low-dose XRT directed to secondary (metastatic) tumors to 'modulate the stroma'. Low-dose XRT improved the antitumor outcomes of checkpoint inhibitors by favoring M1 macrophage polarization, enhancing natural killer (NK) cell infiltration, and reducing TGF-ß levels. Depletion of CD4+ T cells and NK cells abrogated the observed antitumor effect. CONCLUSION: Our data extend the benefits of low-dose XRT to reprogram the tumor environment and improve the infiltration and function of effector immune cells into secondary tumors.

Elevated serum interleukin-8 is associated with enhanced intratumor neutrophils and reduced clinical benefit of immune-checkpoint inhibitors.

Serum interleukin-8 (IL-8) levels and tumor neutrophil infiltration are associated with worse prognosis in advanced cancers. Here, using a large-scale retrospective analysis, we show that elevated baseline serum IL-8 levels are associated with poor outcome in patients (n = 1,344) with advanced cancers treated with nivolumab and/or ipilimumab, everolimus or docetaxel in phase 3 clinical trials, revealing the importance of assessing serum IL-8 levels in identifying unfavorable tumor immunobiology and as an independent biomarker in patients receiving immune-checkpoint inhibitors.

Triple Therapy with MerTK and PD1 Inhibition Plus Radiotherapy Promotes Abscopal Antitumor Immune Responses.

PURPOSE: Radiotherapy (RT) traditionally has been used for local tumor control in the treatment of cancer. The recent discovery that radiotherapy can have anticancer effects on the immune system has led to recognition of its ability to sensitize the tumor microenvironment to immunotherapy. However, radiation can also prompt adverse immunosuppressive effects that block aspects of systemic response at other tumor sites. Our hypothesis was that inhibition of the MER proto-oncogene tyrosine kinase (MerTK) in combination with anti-programmed cell death-1 (α-PD1) checkpoint blockade will enhance immune-mediated responses to radiotherapy. EXPERIMENTAL DESIGN: We tested the efficacy of this triple therapy (Radiation + α-PD1 + α-MerTK mAbs) in 129Sv/Ev mice with bilateral lung adenocarcinoma xenografts. Primary tumors were treated with stereotactic radiotherapy (36 Gy in 3 12-Gy fractions), and tumors were monitored for response. RESULTS: The triple therapy significantly delayed abscopal tumor growth, improved survival rates, and reduced numbers of lung metastases. We further found that the triple therapy increased the activated CD8+ and NK cells populations measured by granzyme B expression with upregulation of CD8+CD103+ tissue-resident memory cells (TRM) within the abscopal tumor microenvironment relative to radiation only. CONCLUSIONS: The addition of α-PD1 + α-MerTK mAbs to radiotherapy could alter the cell death to be more immunogenic and generate adaptive immune response via increasing the retention of TRM cells in the tumor islets of the abscopal tumors which was proven to play a major role in survival of non-small cell lung cancer patients.

Predictive Analysis Using Chemical-Gene Interaction Networks Consistent with Observed Endocrine Activity and Mutagenicity of U.S. Streams.

In a recent U.S. Geological Survey/U.S. Environmental Protection Agency study assessing more than 700 organic compounds in 38 streams, in vitro assays indicated generally low estrogen, androgen, and glucocorticoid receptor activities, with 13 surface waters with 17ß-estradiol-equivalent (E2Eq) activities greater than a 1-ng/L estimated effects-based trigger value for estrogenic effects in male fish. Among the 36 samples assayed for mutagenicity in the Salmonella bioassay (reported here), 25% had low mutagenic activity and 75% were not mutagenic. Endocrine and mutagenic activities of the water samples were well correlated with each other and with the total number and cumulative concentrations of detected chemical contaminants. To test the predictive utility of knowledge-base-leveraging approaches, site-specific predicted chemical-gene (pCGA) and predicted analogous pathway-linked (pPLA) association networks identified in the Comparative Toxicogenomics Database were compared with observed endocrine/mutagenic bioactivities. We evaluated pCGA/pPLA patterns among sites by cluster analysis and principal component analysis and grouped the pPLA into broad mode-of-action classes. Measured E2eq and mutagenic activities correlated well with predicted pathways. The pPLA analysis also revealed correlations with signaling, metabolic, and regulatory groups, suggesting that other effects pathways may be associated with chemical contaminants in these waters and indicating the need for broader bioassay coverage to assess potential adverse impacts.

The Fast Real-time Assessment of Combination Therapies in Immuno-ONcology (FRACTION) program: innovative, high-throughput clinical screening of immunotherapies.

BACKGROUND: The unprecedented success of immuno-oncology (I-O) agents targeting the cytotoxic T lymphocyte-associated antigen 4 and programmed death-1/programmed death-ligand 1 pathways has stimulated the rapid development of other I-O agents against novel immune targets. Bristol-Myers Squibb has designed a novel phase II platform trial, the Fast Real-time Assessment of Combination Therapies in Immuno-ONcology (FRACTION) Program, to efficiently identify promising combinations for patients with specific malignancies. The concept and study design of the FRACTION Program-currently ongoing in patients with advanced non-small-cell lung cancer (FRACTION-Lung), gastric cancer (FRACTION-Gastric Cancer) and renal cell carcinoma (FRACTION-RCC)-are described. METHODS: The FRACTION Program comprises open-label, phase II studies that use adaptive randomisation designs with rolling combination regimens. Master Protocols provide the overall study design framework, whereas Sub-Protocols introduced over time provide details on specific I-O combination therapies to which patients may be randomised. In a Master Protocol, patients are enrolled into different Study Tracks based on characteristics such as prior I-O therapy experience. Patients who progress may be rerandomised to other combination regimens from any ongoing Sub-Protocol. Primary objectives are to assess objective response rate, median duration of response and progression-free survival rate at 24 weeks; the secondary objective is to investigate safety and tolerability. Biomarker collection before and on treatment will facilitate identification of patient subsets who benefit most from each therapy. CONCLUSIONS: The FRACTION Program allows for the evaluation of multiple I-O combinations through individual studies for specific tumours using an adaptive trial design and continuous enrolment.

The Hemoglobin Homolog Cytoglobin in Smooth Muscle Inhibits Apoptosis and Regulates Vascular Remodeling.

OBJECTIVE: The role of hemoglobin and myoglobin in the cardiovascular system is well established, yet other globins in this context are poorly characterized. Here, we examined the expression and function of cytoglobin (CYGB) during vascular injury. APPROACH AND RESULTS: We characterized CYGB content in intact vessels and primary vascular smooth muscle (VSM) cells and used 2 different vascular injury models to examine the functional significance of CYGB in vivo. We found that CYGB was strongly expressed in medial arterial VSM and human veins. In vitro and in vivo studies indicated that CYGB was lost after VSM cell dedifferentiation. In the rat balloon angioplasty model, site-targeted delivery of adenovirus encoding shRNA specific for CYGB prevented its reexpression and decreased neointima formation. Similarly, 4 weeks after complete ligation of the left common carotid, Cygb knockout mice displayed little to no evidence of neointimal hyperplasia in contrast to their wild-type littermates. Mechanistic studies in the rat indicated that this was primarily associated with increased medial cell loss, terminal uridine nick-end labeling staining, and caspase-3 activation, all indicative of prolonged apoptosis. In vitro, CYGB could be reexpressed after VSM stimulation with cytokines and hypoxia and loss of CYGB sensitized human and rat aortic VSM cells to apoptosis. This was reversed after antioxidant treatment or NOS2 (nitric oxide synthase 2) inhibition. CONCLUSIONS: These results indicate that CYGB is expressed in vessels primarily in differentiated medial VSM cells where it regulates neointima formation and inhibits apoptosis after injury.

Three-year outcomes after acute kidney injury: results of a prospective parallel group cohort study.

OBJECTIVES: Using a prospective study design, we aimed to characterise the effect of acute kidney injury (AKI) on long-term changes in renal function in a general hospital population. PARTICIPANTS: Hospitalised patients with AKI (exposed) and hospitalised patients without AKI (non-exposed), recruited at 3 months after hospital admission. DESIGN: Prospective, matched parallel group cohort study, in which renal function and proteinuria were measured at 3 months, 1 year and 3 years. SETTING: Single UK centre. CLINICAL END POINTS: Clinical end points at 3 years were comparison of the following variables between exposed and non-exposed groups: renal function, prevalence of proteinuria and albuminuria and chronic kidney disease (CKD) progression/development at each time point. CKD progression was defined as a decrease in the estimated glomerular filtration rate (eGFR) of ≥25% associated with a decline in eGFR stage. RESULTS: 300 exposed and non-exposed patients were successfully matched 1:1 for age and baseline renal function; 70% of the exposed group had AKI stage 1. During follow-up, the AKI group had lower eGFR than non-exposed patients at each time point. At 3 years, the mean eGFR was 60.7±21 mL/min/1.73 m2 in the AKI group compared with 68.4±21 mL/min/1.73 m2 in the non-exposed group, p=0.003. CKD development or progression at 3 years occurred in 30 (24.6%) of the AKI group compared with 10 (7.5%) of the non-exposed group, p<0.001. Albuminuria was more common in the AKI group, and increased with AKI severity. Factors independently associated with CKD development/progression after AKI were non-recovery at 90 days, male gender, diabetes and recurrent AKI. CONCLUSIONS: AKI is associated with deterioration in renal function to 3 years, even in an unselected population with predominantly AKI stage 1. Non-recovery from AKI is an important factor determining long-term outcome.

Expanded Target-Chemical Analysis Reveals Extensive Mixed-Organic-Contaminant Exposure in U.S. Streams.

Surface water from 38 streams nationwide was assessed using 14 target-organic methods (719 compounds). Designed-bioactive anthropogenic contaminants (biocides, pharmaceuticals) comprised 57% of 406 organics detected at least once. The 10 most-frequently detected anthropogenic-organics included eight pesticides (desulfinylfipronil, AMPA, chlorpyrifos, dieldrin, metolachlor, atrazine, CIAT, glyphosate) and two pharmaceuticals (caffeine, metformin) with detection frequencies ranging 66-84% of all sites. Detected contaminant concentrations varied from less than 1 ng L-1 to greater than 10 µg L-1, with 77 and 278 having median detected concentrations greater than 100 ng L-1 and 10 ng L-1, respectively. Cumulative detections and concentrations ranged 4-161 compounds (median 70) and 8.5-102 847 ng L-1, respectively, and correlated significantly with wastewater discharge, watershed development, and toxic release inventory metrics. Log10 concentrations of widely monitored HHCB, triclosan, and carbamazepine explained 71-82% of the variability in the total number of compounds detected (linear regression; p-values: < 0.001-0.012), providing a statistical inference tool for unmonitored contaminants. Due to multiple modes of action, high bioactivity, biorecalcitrance, and direct environment application (pesticides), designed-bioactive organics (median 41 per site at µg L-1 cumulative concentrations) in developed watersheds present aquatic health concerns, given their acknowledged potential for sublethal effects to sensitive species and lifecycle stages at low ng L-1.

Completeness, accuracy, and readability of Wikipedia as a reference for patient medication information.

OBJECTIVES: This study determined the completeness, accuracy, and reading level of Wikipedia patient drug information compared with the corresponding United States product insert medication guides. METHODS: From the Top 200 Drugs of 2012, the top 33 medications with medication guides were analyzed. Medication guides and Wikipedia pages were downloaded on a single date to ensure continuity of Wikipedia content. To quantify the completeness and accuracy of the Wikipedia medication information, a scoring system was adapted from previously published work and compared with the 7 core domains of medication guides. RESULTS: Wikipedia did not provide patient information that was as complete or accurate as the information within the medication guides: 14.73 out of 42 (SD 5.75). Wikipedia medication pages were written at a significantly higher reading level compared with medication guides (Flesch reading ease score 52.93 vs. 33.24 [P <0.001]; Flesch-Kincaid grade level 10.26 vs. 6.86 [P <0.001]). CONCLUSION: Wikipedia medication pages include incomplete and inaccurate patient information compared with the corresponding product medication guides. Wikipedia patient drug information was also written at reading levels above that of medication guides and substantially above the average United States consumer health literacy level. As the public use of Wikipedia increases, the need for educating patients about the quality of information on Wikipedia and the availability of adequate patient education resources is ever more important to minimize inaccuracies and incomplete information sharing.

Comparison of Two Versions of the Beers Criteria and Adverse Outcomes in Older Hospitalized Patients.

OBJECTIVE: To compare the performance of the 2003 and 2012 Beers criteria (BC) to predict negative clinical outcomes associated with potentially inappropriate medications in hospitalized older adults. DESIGN: Retrospective cohort study. SETTING: Acute Care of Elders (ACE) unit in a community-based teaching hospital. PARTICIPANTS: All patients admitted to an ACE unit who were older than 65 years of age and prescribed at least one medication upon hospital admission. MAIN OUTCOME MEASURE(S): The primary outcome was hospital length of stay (LOS). Secondary outcomes included likelihood of experiencing adverse drug events (ADEs) and in-hospital mortality. RESULTS: A total of 340 patients were included in this study. Inpatients prescribed a BC drug at any time had a longer hospital LOS than those not prescribed a BC drug (2003 BC: adjusted geometric mean, 5.93 vs. 5.50 days, P = 0.003; 2012 BC: adjusted geometric mean, 5.87 vs. 4.21 days, P < 0.001). Patients prescribed a 2003 BC drug had an increased risk of experiencing an ADE compared with those not prescribed a BC drug (odds ratio [OR] = 1.86, 95% confidence interval [CI] 1.11-3.11); however, this outcome was not statistically significant after adjusting for confounders (OR = 1.51, 95% CI 0.870-2.63). There was no statistically significant difference in ADEs when using the 2012 BC (adjusted OR = 1.27, 95% CI 0.689-2.33). There was no difference in hospital mortality regardless of the BC version used. CONCLUSION: Prescription of BC drugs in an acute care setting is associated with an increased hospital LOS; however, there is no difference in the risk of ADEs or in-hospital mortality.

Accuracy and completeness of drug information in Wikipedia medication monographs.

OBJECTIVES: The primary objective of this study was to determine the accuracy and completeness of drug information on Wikipedia and Micromedex compared with U.S. Food and Drug Administration-approved U.S. product inserts. METHODS: The top 10 brand and top 10 generic medications from the 2012 Institute for Health Informatics' list of top 200 drugs were selected for evaluation. Wikipedia medication information was evaluated and compared with Micromedex in 7 sections of drug information; the U.S. product inserts were used as the standard comparator. RESULTS: Wikipedia demonstrated significantly lower completeness and accuracy scores compared with Micromedex (mean composite scores 18.55 vs. 38.4, respectively; P <0.01). No difference was found between the mean composite scores for brand versus generic drugs in either reference (17.8 vs. 19.3, respectively [P = 0.62], for Wikipedia; 39.2 vs. 37.6, [P = 0.06] for Micromedex). Limitations to these results include the speed with which information is edited on Wikipedia, that there was no evaluation of off-label information, and the limited number of drugs that were evaluated. CONCLUSION: Wikipedia lacks the accuracy and completeness of standard clinical references and should not be a routine part of clinical decision making. More research should be conducted to evaluate the rationale for health care providers' use of Wikipedia.

Environmental implications of the use of sulfidic back-bay sediments for dune reconstruction - Lessons learned post Hurricane Sandy.

Some barrier-island dunes damaged or destroyed by Hurricane Sandy's storm surges in October 2012 have been reconstructed using sediments dredged from back bays. These sand-, clay-, and iron sulfide-rich sediments were used to make berm-like cores for the reconstructed dunes, which were then covered by beach sand. In November 2013, we sampled and analyzed partially weathered materials collected from the cores of reconstructed dunes. There are generally low levels of metal toxicants in the reconstructed dune materials. However oxidation of reactive iron sulfides by percolating rainwater produces acid-sulfate pore waters, which evaporate during dry periods to produce efflorescent gypsum and sodium jarosite salts. The results suggest use of sulfidic sediments in dune reconstruction has both drawbacks (e.g., potential to generate acid runoff from dune cores following rainfall, enhanced corrosion of steel bulwarks) and possible benefits (e.g., efflorescent salts may enhance structural integrity).

A simple care bundle for use in acute kidney injury: a propensity score-matched cohort study.

BACKGROUND: Consensus guidelines for acute kidney injury (AKI) have recommended prompt treatment including attention to fluid balance, drug dosing and avoidance of nephrotoxins. These simple measures can be incorporated in a care bundle to facilitate early implementation. The objective of this study was to assess the effect of compliance with the AKI care bundle (AKI-CB) on in-hospital case-fatality and AKI progression. METHODS: In this larger, propensity score-matched cohort of multifactorial AKI, we examined the impact of compliance with an AKI-CB in 3717 consecutive episodes of AKI in 3518 patients between 1 August 2013 and 31 January 2015. Propensity score matching was performed to match 939 AKI events where the AKI-CB was completed with 1823 AKI events where AKI-CB was not completed. RESULTS: The AKI-CB was completed in 25.6% of patients within 24 h. The unadjusted case-fatality was higher when the AKI-CB was not completed versus when the AKI-CB was completed (24.4 versus 20.4%, P = 0.017). In multivariable analysis, AKI-CB completion within 24 h was associated with lower odds for in-hospital death [odds ratio (OR): 0.76; 95% confidence interval (95% CI): 0.62-0.92]. Increasing age (OR: 1.04; 95% CI: 1.03-1.05), hospital-acquired AKI (OR: 1.28; 95% CI: 1.04-1.58), AKI stage 2 (OR: 1.91; 95% CI: 1.53-2.39) and increasing Charlson's comorbidity index (CCI) [OR: 3.31 (95% CI: 2.37-4.64) for CCI of more than 5 compared with zero] had higher odds for death, whereas AKI during elective admission was associated with lower odds for death (OR: 0.29; 95% CI: 0.16-0.52). Progression to higher AKI stages was lower when the AKI-CB was completed (4.2 versus 6.7%, P = 0.02). CONCLUSIONS: Compliance with an AKI-CB was associated with lower mortality and reduced progression of AKI to higher stages. The AKI-CB is simple and inexpensive, and could therefore be applied in all healthcare settings to improve outcomes.

Sediment chemistry and toxicity in Barnegat Bay, New Jersey: Pre- and post-Hurricane Sandy, 2012-13.

Hurricane Sandy made landfall in Barnegat Bay, October, 29, 2012, damaging shorelines and infrastructure. Estuarine sediment chemistry and toxicity were investigated before and after to evaluate potential environmental health impacts and to establish post-event baseline sediment-quality conditions. Trace element concentrations increased throughout Barnegat Bay up to two orders of magnitude, especially north of Barnegat Inlet, consistent with northward redistribution of silt. Loss of organic compounds, clay, and organic carbon is consistent with sediment winnowing and transport through the inlets and sediment transport modeling results. The number of sites exceeding sediment quality guidance levels for trace elements tripled post-Sandy. Sediment toxicity post-Sandy was mostly unaffected relative to pre-Sandy conditions, but at the site with the greatest relative increase for trace elements, survival rate of the test amphipod decreased (indicating degradation). This study would not have been possible without comprehensive baseline data enabling the evaluation of storm-derived changes in sediment quality.

Regional variability in bed-sediment concentrations of wastewater compounds, hormones and PAHs for portions of coastal New York and New Jersey impacted by hurricane Sandy.

Bed sediment samples from 79 coastal New York and New Jersey, USA sites were analyzed for 75 compounds including wastewater associated contaminants, PAHs, and other organic compounds to assess the post-Hurricane Sandy distribution of organic contaminants among six regions. These results provide the first assessment of wastewater compounds, hormones, and PAHs in bed sediment for this region. Concentrations of most wastewater contaminants and PAHs were highest in the most developed region (Upper Harbor/Newark Bay, UHNB) and reflected the wastewater inputs to this area. Although the lack of pre-Hurricane Sandy data for most of these compounds make it impossible to assess the effect of the storm on wastewater contaminant concentrations, PAH concentrations in the UHNB region reflect pre-Hurricane Sandy conditions in this region. Lower hormone concentrations than predicted by the total organic carbon relation occurred in UHNB samples, suggesting that hormones are being degraded in the UHNB region.

Young of the year bluefish (Pomatomus saltatrix) as a bioindicator of estuarine health: Establishing a new baseline for persistent organic pollutants after Hurricane Sandy for selected estuaries in New Jersey and New York.

Atlantic coastal bays of the US are essential habitat for young of year bluefish (Pomatomus saltatrix). Their residence in these estuaries during critical life stages, high lipid content, and piscivory make bluefish an ideal bioindicator species for evaluating estuarine health. Individual whole fish from four estuaries impacted by Hurricane Sandy were collected in August 2013, analyzed for a suite of persistent organic pollutants (POPs) including polychlorinated biphenyls, polybrominated diphenyl ethers and organochlorine pesticides and evaluated using health metrics. Concentrations in whole bluefish differed by estuary; however, concentrations for many POPs decreased or were similar to those observed prior to the hurricane. Prevalence of the ectoparasitic gill isopod (Lironeca ovalis) varied by estuary and no relationships between contaminants and lesions were observed. Bluefish should be considered for monitoring programs and, if sampled frequently, could be an effective bioindicator of incremental and episodic changes in contaminants within aquatic food webs.
