Vulnerability to climate change of United States marine mammal stocks in the western North Atlantic, Gulf of Mexico, and Caribbean.

Climate change and climate variability are affecting marine mammal species and these impacts are projected to continue in the coming decades. Vulnerability assessments provide a framework for evaluating climate impacts over a broad range of species using currently available information. We conducted a trait-based climate vulnerability assessment using expert elicitation for 108 marine mammal stocks and stock groups in the western North Atlantic, Gulf of Mexico, and Caribbean Sea. Our approach combined the exposure (projected change in environmental conditions) and sensitivity (ability to tolerate and adapt to changing conditions) of marine mammal stocks to estimate vulnerability to climate change, and categorize stocks with a vulnerability index. The climate vulnerability score was very high for 44% (n = 47) of these stocks, high for 29% (n = 31), moderate for 20% (n = 22), and low for 7% (n = 8). The majority of stocks (n = 78; 72%) scored very high exposure, whereas 24% (n = 26) scored high, and 4% (n = 4) scored moderate. The sensitivity score was very high for 33% (n = 36) of these stocks, high for 18% (n = 19), moderate for 34% (n = 37), and low for 15% (n = 16). Vulnerability results were summarized for stocks in five taxonomic groups: pinnipeds (n = 4; 25% high, 75% moderate), mysticetes (n = 7; 29% very high, 57% high, 14% moderate), ziphiids (n = 8; 13% very high, 50% high, 38% moderate), delphinids (n = 84; 52% very high, 23% high, 15% moderate, 10% low), and other odontocetes (n = 5; 60% high, 40% moderate). Factors including temperature, ocean pH, and dissolved oxygen were the primary drivers of high climate exposure, with effects mediated through prey and habitat parameters. We quantified sources of uncertainty by bootstrapping vulnerability scores, conducting leave-one-out analyses of individual attributes and individual scorers, and through scoring data quality for each attribute. These results provide information for researchers, managers, and the public on marine mammal responses to climate change to enhance the development of more effective marine mammal management, restoration, and conservation activities that address current and future environmental variation and biological responses due to climate change.

Prognosis does not change the landscape: palliative home care clients experience high rates of pain and nausea, regardless of prognosis.

BACKGROUND: Most individuals who typically receive palliative care (PC) tend to have cancer and a relatively short prognosis (< 6 months). People with other life-limiting illnesses can also benefit from a palliative care approach. However, little is known about those who receive palliative home care in Ontario, Canada's largest province. To address this gap, the goal of this project was to understand the needs, symptoms and potential differences between those with a shorter (< 6 months) and longer prognosis (6+ months) for individuals receiving PC in the community. METHODS: A cross-sectional analysis was conducted using interRAI Palliative Care (interRAI PC) assessment data collected between 2011 and 2018. Individuals with a shorter prognosis (< 6 months; n = 48,019 or 64.1%) were compared to those with a longer prognosis (6+ months; n = 26,945) across several clinical symptoms. The standardized difference (stdiff), between proportions, was calculated to identify statistically meaningful differences between those with a shorter and longer prognosis. Values of the stdiff of 0.2 or higher (absolute value) indicated a statistically significant difference. RESULTS: Overall, cancer was the most prevalent diagnosis (83.2%). Those with a shorter prognosis were significantly more likely to experience fatigue (75.3% vs. 59.5%; stdiff = 0.34) and shortness of breath at rest (22.1% vs. 13.4%; stdiff = 0.23). However, the two groups were similar in terms of severe pain (73.5% vs. 66.5%; stdiff = - 0.15), depressive symptoms (13.2% vs. 10.7%; stdiff = 0.08) and nausea (35.7% vs. 29.4%; stdiff = 0.13). CONCLUSIONS: These results highlight the importance of earlier identification of individuals who could benefit from a palliative approach to their care as individuals with a longer prognosis also experience high rates of symptoms such as pain and nausea. Providing PC earlier in the illness trajectory has the potential to improve an individual's overall quality of life throughout the duration of their illness.

Symptom trajectories of non-cancer patients in the last six months of life: Identifying needs in a population-based home care cohort.

INTRODUCTION: The end-of-life symptom prevalence of non-cancer patients have been described mostly in hospital and institutional settings. This study aims to describe the average symptom trajectories among non-cancer patients who are community-dwelling and used home care services at the end of life. MATERIALS AND METHODS: This is a retrospective, population-based cohort study of non-cancer patients who used home care services in the last 6 months of life in Ontario, Canada, between 2007 and 2014. We linked the Resident Assessment Instrument for Home Care (RAI-HC) (standardized home care assessment tool) and the Discharge Abstract Databases (for hospital deaths). Patients were grouped into four non-cancer disease groups: cardiovascular, neurological, respiratory, and renal (not mutually exclusive). Our outcomes were the average prevalence of these outcomes, each week, across the last 6 months of life: uncontrolled moderate-severe pain as per the Pain Scale, presence of shortness of breath, mild-severe cognitive impairment as per the Cognitive Performance Scale, and presence of caregiver distress. We conducted a multivariate logistic regression to identify factors associated with having each outcome respectively, in the last 6 months. RESULTS: A total of 20,773 non-cancer patient were included in our study, which were analyzed by disease groups: cardiovascular (n = 12,923); neurological (n = 6,935); respiratory (n = 6,357); and renal (n = 3,062). Roughly 80% of patients were > 75 years and half were female. In the last 6 months of life, moderate to severe pain was frequent in the cardiovascular (57.2%), neurological (42.7%), renal (61.0%) and respiratory (58.3%) patients. Patients with renal disease had significantly higher odds for reporting uncontrolled moderate to severe pain (odds ratio [OR] = 1.21; 95% CI: 1.08 to 1.34) than those who did not. Patients with respiratory disease reported significantly higher odds for shortness of breath (5.37; 95% CI, 5.00 to 5.80) versus those who did not. Patients with neurological disease compared to those without were 9.65 times more likely to experience impaired cognitive performance and had 56% higher odds of caregiver distress (OR = 1.56; 95% CI: 1.43 to 1.71). DISCUSSION: In our cohort of non-cancer patients dying in the community, pain, shortness of breath, impaired cognitive function and caregiver distress are important symptoms to manage near the end of life even in non-institutional settings.

Trajectory of End-of-Life Pain and Other Physical Symptoms among Cancer Patients Receiving Home Care.

PURPOSE: To describe the trajectory of physical symptoms among cancer decedents who were receiving home care in the six months before death. PATIENTS AND METHODS: An observational cohort study of cancer decedents in Ontario, Canada, who received home care services between 2007 and 2014. To be included, decedents had to use at least one home care service in the last six months of life. Outcomes were the presence of pain and several other physical symptoms at each week before death. RESULTS: Our cohort included 27,295 cancer decedents (30,368 assessments). Forty-seven percent were female and 56% were age 75 years or older. The prevalence of all physical symptoms increased as one approached death, particularly in the last month of life. In the last weeks of life, 69% of patients reported having moderate-severe pain; however, only 20% reported that the pain was not controlled. Loss of appetite (63%), shortness of breath (59%), high health instability (50%), and self-reported poor health (44%) were also highly prevalent in the last week of life. Multivariate regression showed that caregiver distress, high health instability, social decline, uncontrolled pain, and signs of depression all worsened the odds of having a physical symptom in the last 3 months of life. CONCLUSION: In this large home care cancer cohort, trajectories of physical symptoms worsened close to death. While presence of moderate-severe pain was common, it was also reported as mostly controlled. Covariates, such as caregiver distress and social decline, were associated with having more physical symptoms at end of life.

Trajectory of psychosocial symptoms among home care patients with cancer at end-of-life.

PURPOSE: Understanding the end-of-life psychosocial needs of cancer patients at home is a knowledge gap. This study describes the trajectory of psychosocial symptoms in the last 6 months of life among cancer decedents who were receiving home care. METHODS: Observational population-based cohort study of cancer decedents who were receiving home care services between 2007 and 2014. Decedents had to have at least one home care assessment in the last 6 months of life for inclusion. Outcomes were the presence of psychosocial symptoms (i.e., anxiety, loneliness, depression, social decline, caregiver distress, and cognitive decline) at each week before death. RESULTS: Our cohort included 27,295 unique cancer decedents (30,368 assessments), of which 58% died in hospital. Fifty-six percent were older than 74, and 47% were female. The prevalence of all symptoms increased approaching death, except loneliness. Social decline (48%-78%) was the most prevalent psychosocial symptom, though loneliness was reported in less than 10% of the cohort. Caregiver distress rose over time from 15%-27%. A third of the cohort reported issues with cognitive impairment. Multivariate regression showed that physical symptoms such as uncontrolled pain, impairment in independent activities of daily living, and a high level of health instability all significantly worsened the odds of having a psychosocial symptom in the last 3 months of life. CONCLUSION: In this large home care cancer cohort, trajectories of psychosocial symptoms worsened close to death. Physical symptoms, such as uncontrolled pain, were associated with having worse psychosocial symptoms at end of life.

Cross-Sectional Nutrition Profile of Palliative Home Care Clients in Ontario and Performance of the interRAI Palliative Care Nutrition Clinical Assessment Protocol.

BACKGROUND: The nutrition profile of palliative home care clients is unknown. This study describes this group and their nutrition issues and evaluates the performance of the interRAI nutrition Clinical Assessment Protocol (CAP). METHODS: This was a cross-sectional secondary analysis using Ontario interRAI Palliative Care (interRAI PC) Assessment data. The sample represents 74,963 unique Ontario home care clients assessed between 2011 and 2018. Frequencies and standardized differences (stdiffs) of nutrition characteristics were presented for cancer (n = 62,394) and noncancer (n = 12,569) diagnostic subgroups. Rates of triggering the nutrition CAP were presented by nutrition issue to evaluate its performance. RESULTS: Of this sample, 16.7% were ≥85 years of age, 52.6% had a prognosis between 6 weeks and 6 months, and 41.4% required assistance with eating. The prevalence was higher among those with nervous/mental/behavioral disorders (72.6%) compared with those with cancer (37.6%; stdiff = 0.75). However, most nutrition issues experienced were similar (stdiff < 0.20) across diagnostic groups. Of the entire sample, 21% triggered the nutrition CAP, indicating a need for further evaluation or intervention. Yet, 73.4% of those who experienced dry mouth, 71.8% of those who required assistance with eating, and 68.4% of those who received a nutrition consult within the last 3 days did not trigger the nutrition CAP. CONCLUSIONS: Nutrition issues are prevalent in palliative home care clients, regardless of diagnosis; yet the nutrition CAP identified a small fraction of this group. There is a need to focus research and care guidelines toward life-limiting illnesses beyond cancer and address nutrition-related issues in this population.

Care Coordination with Schools: The Role of Family-Centered Care for Children with Special Health Care Needs.

Objectives Family-centered care has been associated with positive outcomes for children with special health care needs. The purpose of the current study was to examine the relationship of family-centered care as associated with care coordination with schools and school absences (e.g., missed days) as reported by parents of children with special health care needs. Methods The current study utilized data from the National Survey of Children with Special Health Care Needs 2009-201 (N = 40,242) to achieve this purpose. The National Survey of Children with Special Health Care Needs may be considered a nationally-representative and community-based sample of parent responses for children with special health care needs across the United States. Results Results from the current study indicate that family-centered care is associated with fewer absences and improved care coordination with schools when applicable. The variables of functional difficulties, poverty level, and the number of conditions were statistically controlled. Conclusions We suggest that the positive influence of family-centered care when practiced extends beyond the family and interacts with educational outcomes. We also suggest that the role of schools appears to be under-studied given the role that schools can play in family-centered care.

The importance of ADHD subtype classification for educational applications of DSM-V.

OBJECTIVE: An examination of the academic achievement of children with ADHD by stimulant treatment status must consider this heterogeneity of the disorder. With the dissemination of the final wave of data, the Special Education Elementary Longitudinal Study presents an opportunity to examine the academic achievement of students with ADHD using a large, community-based, and nationally representative sample over 4 years. METHOD: In Study 1, the association between stimulant treatment and academic achievement is examined over 4 years. In Study 2, the association between stimulant treatment and academic achievement is examined acknowledging the influence of subtype symptoms of ADHD using growth mixture modeling. RESULTS: Results indicate significant differences in academic achievement according to long-term stimulant treatment status within each subtype symptom class. CONCLUSION: Research should acknowledge the influence of subtype symptoms when examining outcomes such as academic achievement. The upcoming DSM-V should consider the results as indicating the educational relevance of ADHD subtype classification.

There is no meaningful relationship between television exposure and symptoms of attention-deficit/hyperactivity disorder.

OBJECTIVE: The recent but methodologically limited longitudinal study of the adverse attentional effects of television viewing in early childhood suggests a possible association. The purpose of the present study was to extend this investigation to a more current sample of kindergarten students using structural equation modeling, which allows for the simultaneous evaluation of predictors. METHODS: Two samples were randomly selected from nationally representative data collected from the Early Childhood Longitudinal Study. A structural equation model was developed positing a relationship between kindergartners' television exposure and subsequent first-grade symptoms of attention-deficit/hyperactivity disorder (ADHD) while controlling for variables related to socioeconomic status and parent involvement. Variables were selected rather than developed and do not include an acceptable measure of ADHD, which limited the scope of the measures used. The model was tested by using the first sample and then cross-validated to the second sample. RESULTS: Although the adequate fit of the model to the data suggests that children's television exposure during kindergarten was related to symptoms of ADHD during the first grade, the amount of variance accounted for in the ADHD-symptoms variable revealed television exposure as a weak predictor of later ADHD symptoms. Effect sizes for the relationship between television exposure and symptoms of ADHD were close to zero and not statistically significant. CONCLUSIONS: Methodologic issues, including participant age, the measurement of ADHD symptoms, and evaluation of the importance of variables, may explain the differences between the present study and the results of others who have found television exposure to be related to attention problems. The measurement of ADHD symptoms through the use of longitudinal databases is an important limitation, because only a small number of items can be selected to represent symptoms. Future research is necessary to address these issues.
