Abstract
PURPOSE Physical activity (PA) is proposed for long-term problems after traumatic brain injury (TBI) with mood, quality of life, and participation. However, COVID-19 mitigation strategies resulted in widespread closures of community-based fitness centres, including one housing a peer-assisted PA program (TBI-Health). The purpose of this study was to provide an in-depth exploration of COVID-19's impact on the TBI-Health program for adults with moderate-to-severe TBI and determine how their PA behaviours could be supported in the pandemic. METHODS Interpretative phenomenological analysis was employed to collect and analyze data from semi-structured Zoom-facilitated interviews with seven female and nine male adults with moderate-to-severe TBI (including program participants and mentors). RESULTS Three major themes were identified. Need for PA after TBI included specific benefits of PA after TBI and desire for an adapted PA program. Lasting Impacts of the TBI-Health Program identified belonging to the TBI-Health community, benefits, and knowledge transfer from the program. Resilience and Loss through the Pandemic comprised the repercussions of COVID-19, loss of the PA program, adapting PA to the pandemic, and resilience after TBI. CONCLUSION This study provides insights about impacts of participating in community-based peer-assisted PA programs after moderate-to-severe TBI and ways to support PA in unforeseen circumstances.

Abstract
Background: Polysomnographic (PSG) findings of persons with mild traumatic brain injury (mTBI)/concussion show longer total sleep time than patients themselves report; the reason for this is not entirely clear.Objective: This study aimed to elucidate the socio-demographic, brain-injury-related, and clinical characteristics that underlie accuracy of sleep duration reporting in mTBI/concussion.Methods: Thirty-seven participants diagnosed with mTBI/concussion (57% male, 47.54 ± 11.3 years old) underwent clinical and neuroimaging examinations, full-night PSG, and estimated sleep duration following PSG.Results: Mean self-reported sleep duration was 342 ± 93.6 minutes and PSG-measured sleep duration was 382 ± 76.8 minutes. Measurements were moderately correlated (rho = 0.46, p = .004). Age associated with self- and PSG-measured sleep duration (rho = 0.34 and rho = 0.84, respectively, p < .05). Self-reported sleep duration was uniquely associated with insomnia severity (rho = -0.48, p = .002). In the fully adjusted multivariable regression analysis, several clinical characteristics of patients explained 30% of the discrepancy between self- and PSG-measured sleep duration.Conclusion: The observed results indicate that persons with mTBI do not accurately assess their sleep duration and, therefore, PSG is warranted in clinical situations where sleep duration is of concern.

Critical methodological considerations in recruiting and engaging non-native English speaking workers with a head injury: a Canadian perspective. BMC Res Notes 2020; 13:184. [PMID: 32228716 PMCID: PMC7106822 DOI: 10.1186/s13104-020-05028-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/19/2020] [Accepted: 03/17/2020] [Indexed: 11/10/2022] Open
Abstract
OBJECTIVE Non-native English speaking workers with a mild work-related traumatic brain and/or head injury are a vulnerable and underrepresented population in research studies. The researchers present their experiences with recruiting and performing qualitative interviews with non-native English speaking individuals with a work-related mild traumatic brain injury, and provide recommendations on how to better include this vulnerable population in future research studies. This paper presents considerations regarding ethics, recruitment challenges, interview preparation and debriefing, sex & gender and language and cultural issues must be made when working with this vulnerable population. RESULTS The researchers discuss critical issues and provide recommendations in recruiting and engaging with non-native English language workers including ethics, recruitment challenges, interview preparation and debriefing, sex & gender and language, and cultural considerations that must be made when working with this population. The study recommendations advise investigators to spend more time to learn about the non-native English participants in the mild wrTBI context, to be familiar with the vulnerabilities and specific circumstances that these workers experience. By increasing their awareness of the challenging facing this vulnerable population, the intention is to provide better care and treatment options through evidence-based research and practice.

A qualitative exploration of work-related head injury: vulnerability at the intersection of workers' decision making and organizational values. BMC Public Health 2017; 17:824. [PMID: 29047336 PMCID: PMC5648438 DOI: 10.1186/s12889-017-4823-5] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2016] [Accepted: 10/04/2017] [Indexed: 11/18/2022] Open
Abstract
BACKGROUND Work-related head injury is a critical public health issue due to its rising prevalence; the association with profound disruption of workers' lives; and significant economic burdens in terms of medical costs and lost wages. Efforts to understand and prevent these types of injuries have largely been dominated by epidemiological research and safety science, which has focused on identifying risk at the level of the individual worker, population group, or organizational sector. Limited research has focused on the perspectives of the workers, a key stakeholder group for informing understanding of vulnerability to work-related head injury. This study explored workers' perspectives to better understand their decision-making and how and why their injuries occurred. METHODS We conducted a qualitative study using in-depth semi-structured interviews with thirty-two adult workers who had sustained a work-related head injury. Workers were recruited from an urban clinic in central Ontario, Canada. Labour Process Theory informed the thematic analysis. RESULTS Three hazardous work conditions were identified: insufficient training; inadequate staffing; and inattention to the physical environment. In addition, professional and organizational norms were implicated in vulnerability to head injury including putting the client before the worker and the pressure to work unsafely. The findings also highlight a complex interrelationship between workers' decision-making and professional and organizational norms that produces vulnerability to head injury, a vulnerability which oftentimes is reproduced by workers' decisions to work despite hazardous conditions. CONCLUSIONS Our findings suggest that, beyond the need to redress the inattention to hazards in the physical environment, there is a need to address norms that influence worker decision-making to improve the safety of workers. Using Labour Process Theory highlights an important social dynamic within workplace sectors that could inform future development and implementation of multi-level and integrated public health strategies to reduce work-related head injury.

Abstract
BACKGROUND Returning to work is one of the most important goals cited by individuals with traumatic brain injury (TBI). However, they may have difficulty evoking past work history. The ability to recall work history is integral to the rehabilitation process of return to work. OBJECTIVE The aim of this study was to determine 1) the level of agreement on the reporting of occupations and 2) if agreement is affected when specific occupational details are required in recall between adults with traumatic brain injury and their informants. METHODS This is a retrospective cohort study of 259 individuals, with moderate to severe traumatic brain injury, and their selected informants (e.g. spouse, parent). Interviews were conducted separately for the individual and respective informant to gather information on type of occupation at time of injury and at time of interview. Reported occupations were coded using a standard classification system. Level of agreement was analyzed by interclass correlation coefficients and percent agreement, and the significance of bias was calculated. RESULTS Participants were a mean age of 44.5 at time of study with 40% employed compared to 77% at time of injury. Agreement between participants and their informants for occupational title was high for both time periods though more so at the time of injury compared to current status. Level of agreement for specificity was moderate to high however, decreased as need for specificity of detail increased. CONCLUSION While participant-informant responses appear to be reliable for occupational classification, when detailed information is required corroborating information is likely needed.

Abstract
This study examined the effect of Traumatic Brain Injury 10 years post-injury. Frequencies of head injury symptoms and activity limitation by level of severity were measured in a consecutive series of 61 adults who were admitted to a tertiary-care center for traumatic brain injury. Irritability and Anxiety were the most frequently reported symptoms from the Head Injury Symptom Checklist. Bothered by noise and Bothered by light were the least frequently reported. Trouble hearing what is said in a group conversation and Trouble hearing what is said in a one-to-one conversation were the most commonly reported limitations of activity from the Health and Activity Limitations Survey. Overall, this study illustrates that symptoms remain many years following brain injury, irrespective of the injury's severity.

Abstract
HIV-1-specific broadly neutralizing antibodies (bNAbs) can protect rhesus monkeys against simian-human immunodeficiency virus (SHIV) challenge. However, the site of antibody interception of virus and the mechanism of antibody-mediated protection remain unclear. We administered a fully protective dose of the bNAb PGT121 to rhesus monkeys and challenged them intravaginally with SHIV-SF162P3. In PGT121-treated animals, we detected low levels of viral RNA and viral DNA in distal tissues for seven days following challenge. Viral RNA-positive tissues showed transcriptomic changes indicative of innate immune activation, and cells from these tissues initiated infection after adoptive transfer into naïve hosts. These data demonstrate that bNAb-mediated protection against a mucosal virus challenge can involve clearance of infectious virus in distal tissues.

Abstract
The earliest events following mucosal HIV-1 infection, prior to measurable viremia, remain poorly understood. Here, by detailed necropsy studies, we show that the virus can rapidly disseminate following mucosal SIV infection of rhesus monkeys and trigger components of the inflammasome, both at the site of inoculation and at early sites of distal virus spread. By 24 hr following inoculation, a proinflammatory signature that lacked antiviral restriction factors was observed in viral RNA-positive tissues. The early innate response included expression of NLRX1, which inhibits antiviral responses, and activation of the TGF-β pathway, which negatively regulates adaptive immune responses. These data suggest a model in which the virus triggers specific host mechanisms that suppress the generation of antiviral innate and adaptive immune responses in the first few days of infection, thus facilitating its own replication. These findings have important implications for the development of vaccines and other strategies to prevent infection.

Abstract
BACKGROUND Hospitalisations for ambulatory care-sensitive (ACS) conditions are used as an indicator of access to, and the quality of, primary care. The objective was to identify factors associated with hospitalisations for ACS conditions among adults with an intellectual disability (ID) in the context of a publicly insured healthcare system. METHODS This study examined adults with an ID living in a Canadian province between 1999 and 2003 identified from administrative databases. Using 5 years of data for the study population, characteristics of persons hospitalised or not hospitalised for ACS conditions were compared. Using a conceptual model, independent variables were selected and an analysis performed to identify which were associated with hospitalisations for ACS conditions. The correlated nature of the observations was accounted for statistically. RESULTS Living in a rural area [odds ratio (OR) 1.3; 95% confidence intervals (CI) = 1.0, 1.8], living in an area with a high proportion of First Nations people (OR 2.3; 95% CI = 1.3, 4.1), and experiencing higher levels of comorbidity (OR 25.2; 95% CI = 11.9, 53.0) were all associated with a higher likelihood of being hospitalised for an ACS condition. Residing in higher income areas had a protective effect (OR 0.56; 95% CI = 0.37, 0.85). None of the health service resource variables showed statistically significant associations. CONCLUSIONS Persons with an ID experience inequity in hospitalisations for ACS conditions according to rurality, income and proportion who are First Nations in a geographic area. This suggests that addressing the socio-economic problems of poorer areas and specifically areas densely populated by First Nations people may have an impact on the number of hospitalisations for ACS conditions. Study strengths and limitations and areas for potential future research are discussed.

Abstract
OBJECTIVES To examine the nature and extent of persistent post-injury symptoms of persons who have experienced a work-related traumatic brain injury (WrTBI) in Ontario, Canada. METHODS Using a retrospective case series design, post-injury symptoms, occupation, and work factors were examined for WrTBIs among an adult population. Data were abstracted from medical records of individuals who sustained a WrTBI and were discharged from a referral-based outpatient neurology service between the years of 1998 and 2001. RESULTS Of the 435 individuals who sustained a WrTBI, most were ≥ 45 years of age and male. Approximately 50% had injuries to the head only, while others had multiple injuries. The most common post-injury symptoms were headaches (85.1%), memory changes (74.3%), and mood/personality changes (68.3%). A small subset of individuals reported very long-term post-injury symptoms, and a majority of individuals had not yet returned to work. CONCLUSIONS This study profiles the demographic and clinical characteristics of an outpatient injured worker population with a history of WrTBI which provides a basis for the planning and implementation of assessment and treatment programs for this clinical population.

Abstract
BACKGROUND There is evidence that persons with an intellectual disability (ID) face barriers to primary care; however, this has not been extensively studied at the population level. Rates of hospitalisation for ambulatory care sensitive conditions are used as an indicator of access to, and quality of, primary care. The objective of the study was to compare hospitalisation rates for ambulatory care sensitive conditions between persons with and without an ID in a publicly insured population. METHODS Persons with an ID were identified among the general population of a Canadian province between 1999 and 2003. Using a list of conditions applicable to persons with an ID, rates of hospitalisations for ambulatory care sensitive conditions for persons with and without an ID were calculated and compared. Regression models were used to adjust for age, sex and place of residence. Hospitalisation rates for specific conditions were also compared, controlling for differences in disease prevalence where possible. RESULTS Persons with an ID were consistently hospitalised for ambulatory care sensitive conditions at a higher rate than persons without an ID. Between 1999 and 2003 the adjusted rate ratio (RR) was 6.1 [95% confidence interval (CI) = 5.6, 6.7]. Rate ratios were highest when comparing persons with, to persons without, an ID between the ages of 30-39 (RR = 13.1; 95% CI = 10.6, 16.2) and among urban area dwellers (RR = 7.0; 95% CI = 6.2, 7.9). Hospitalisation rates for epilepsy and schizophrenic disorders were, respectively, 54 and 15 times higher for persons with compared with persons without an ID. Rate ratios for diabetes and asthma remained significant after controlling for the population prevalence of these diseases. CONCLUSIONS The large discrepancy in rates of hospitalisation between persons with and without an ID is an indicator of inadequate primary care for this vulnerable population. Decreasing the number of ambulatory care sensitive condition hospitalisations through specialised outpatient programmes for persons with an ID would potentially lead to better health, improved quality of life and cost savings. Future research should include potentially important factors such as disease severity, socio-economic variables and measures of health service organisation in the analysis. International comparisons of ambulatory care sensitive condition hospitalisation rates could point to the benefits and limitations of the health service policy directions adopted by different countries.

Abstract
BACKGROUND Ethnicity is an important determinant of mental health outcomes including suicidality (i.e. suicidal ideation and suicide attempt). Understanding ethnic differences in the pathways to suicidality is important for suicide prevention efforts in ethnically diverse populations. These pathways can be conceptualized within a social stress framework. METHOD The study examines ethnic differences in the pathways to suicidality in Canada within a social stress framework. Using data from the Canadian Community Health Survey Cycle 1.1 (CCHS 1.1) and path analysis, we examined the hypotheses that variations in (1) socio-economic status (SES), (2) sense of community belonging (SCB), (3) SES and SCB combined, and (4) SES, SCB and clinical factors combined can explain ethnic differences in suicidality. RESULTS Francophone whites and Aboriginals were more likely to report suicidality compared to Anglophone whites whereas visible minorities and Foreign-born whites were least likely. Disadvantages in income, income and education, income and its combined effect with depression and alcohol dependence/abuse led to high rates even among the low-risk visible minority group. Indirect pathways for Asians differed from that of Blacks and South Asians, specifically through SCB. With the exception of SCB, Aboriginals were most disadvantaged, which exacerbated their risk for suicidality. However, their strong SCB buffered the risk for suicidality across pathways. Disadvantages in education, income and SCB were associated with the high risk for suicidality in Francophone whites. CONCLUSIONS Francophone whites and Aboriginals had higher odds of suicidality compared to Anglophone whites; however, some pathways differed, indicating the need for targeted program planning and prevention efforts.

Abstract
The current study provides a critical review of Canadian studies on ethnicity and mental health with respect to the definition, conceptualization and operationalization of ethnicity. It provides a discussion on the methodological issues related to these factors and their implications to guide future research and enable comparability of results across studies. Sociological Abstracts, PsycINFO, MEDLINE and CINAHL were used to identify relevant Canadian articles published between January 1980 and December 2004. The review highlights a number of key issues for future researchers to consider such as the need for: 1) clear rationales as to why ethnicity is important to their outcome of interest; 2) clarity on the definition of ethnicity, which affects its conceptualization and operationalization; 3) a theoretically driven conceptualization of ethnicity, which should be related to the research question of interest; and 4) clear rationales for the decisions made regarding the data source used, the operationalization of ethnicity, and the ethnic categories included in their studies.

Abstract
PURPOSE To examine predictors of long-term occupational performance outcomes for adults after moderate to severe traumatic brain injury (TBI). METHOD This study involved analysis of data from a retrospective cohort of adults (N = 306) with moderate to severe TBI discharged from a Pennsylvania rehabilitation treatment facility. Extensive pre-injury sociodemographic, injury-severity, post-injury personal (cognitive, physical, affective), post-injury environmental (social, institutional, physical), and post-injury occupational performance (participation in self-care, productivity, leisure activities) data were gathered from hospital records and using in-person interviews. Interviews occurred at a mean time of 14 (range, 7-24) years post-injury. Hierarchical multiple regression analysis was used to investigate determinants of long-term occupational performance outcomes. RESULTS Pre-injury behavioural problems, male gender, post-injury cognitive and physical deficits, and lack of access to transportation were significant independent predictors of worse occupational performance outcomes. CONCLUSIONS The study supports the use of a comprehensive model for long-term outcomes after TBI where pre-injury characteristics and post-injury cognitive and physical characteristics account for the greatest proportion of explained variance.

Abstract
Although traumatic brain injury (TBI) is a leading cause of death and disability in young adults, older adults over the age of 75 are also at high risk for TBI. As even mild injury can lead to disabling consequences, the long-term consequences of TBI need to be better understood, especially as the survival rate has increased dramatically in the last few decades. This research examined the prevalence of long-term health conditions after TBI. Using a retrospective cohort design, we examined consecutive records of adults with moderate to severe TBI discharged from a large rehabilitation hospital in Pennsylvania from 1974 to 1989. Baseline clinical information was abstracted from medical records. We interviewed consenting participants up to 24 years after injury. Our findings show a higher than expected prevalence of self-reported arthritis in the middle-aged population. There was also a high prevalence of problems with sleep and nerves many years post-injury. Some of the health conditions documented in this study could potentially be addressed early in rehabilitation; this study supports the screening of more physical health conditions in persons aging with TBI.

OBJECTIVE This research examined the long-term outcomes of rehabilitation patients with moderate to severe traumatic brain injury (TBI). DESIGN Retrospective cohort study. SETTING AND SUBJECTS We examined consecutive records of persons with moderate to severe traumatic brain injury who were discharged from a large rehabilitation hospital in Pennsylvania from 1973 to 1989. We interviewed consenting participants (n = 306) up to 24 years post-injury. MAIN OUTCOME MEASURES Self-rated health, activity limitations, employment, living arrangements, marital status, Community Integration Questionnaire, and use of rehabilitation services. RESULTS Participants were most limited in activities such as managing money and shopping. Twenty-nine per cent of our participants were working full time. There were significant relationships between activity limitations and residual cognitive impairment at follow-up. Self-rated health was correlated with most instrumental activities of daily living. CONCLUSION Our findings document health and function in a large post acute TBI population and implications for rehabilitation are discussed.

Mental health and vitality among Canadian women with physical disabilities. Psychol Rep 2003; 93:75-83.

Abstract
This study investigated scores for mental health and vitality in a large community-based sample of women with physical disabilities. The scores from two subscales of the SF-36 were collected from 1,096 women with physical disabilities through a mailed survey regarding health and well-being. These scores were compared to normative data using t tests. The mean scores of the vitality subscale were significantly lower than that of the normed sample when analyzed by age groups. The mental health scores were significantly lower as well, except for one age group (65-74 yr.). These results suggest that health care workers should address aspects of mental health and energy when caring for women with physical disabilities, as these areas are often overlooked in this population. Health promotion programs aimed at these topics should be designed specifically for this population as well.

Abstract
The aim of this paper is to document interest in support strategies among caregivers of elderly persons. We used data from the Canadian Study of Health and Aging caregiver questionnaire which included 43 informal caregivers of elderly persons living with dementia and 145 informal caregivers of elderly persons not living with dementia. While the study assessed interest in attending support groups (10.4%), receiving telephone support from either a professional (44.9%) or a fellow caregiver (41.0%), receiving a newsletter (40.5%), receiving volunteer support (24.2%), and interest in support via computer (14.8%), there were no significant differences between the two groups with regard to interest in any of the support services. Implications for program delivery are discussed. Planners may want to consider adding telephone support and newsletters to other supports already available for caregivers.

Abstract
OBJECTIVES To explore factors associated with perceived quality of life (QOL) 8 to 24 years after traumatic brain injury (TBI). DESIGN Retrospective cohort study. PARTICIPANTS Two hundred seventy-five individuals who sustained moderate to severe TBI who were discharged from a rehabilitation hospital participated in this study. We interviewed consenting participants up to 24 years after injury. OUTCOME MEASURES Self-rated Quality of Life Scale. RESULTS Multivariate linear regression analyses revealed that perceived mental health, self-rated health, gender (women rating QOL higher), participation in work and leisure, and the availability of emotional support were significantly associated with QOL (P <.05). CONCLUSION The importance of designing ongoing support programs to further reintegrate TBI survivors several years after injury is discussed.

Abstract
This paper documents the use and interest in support strategies such as telephone support, newsletters, and computer services, among caregivers of all ages. Data obtained from telephone interviews with community living caregivers of persons with dementia (n = 148) showed substantial interest in the use of these types of services. Using a theoretical framework, this paper identifies caregiver and care-receiver characteristics associated with those interested in the utilization of these support strategies. The implications of these findings for program planning and future research are discussed.

Abstract
This study investigated the types of self-reported main problems that persons report many years following a traumatic brain injury. This preliminary study is part of a large ongoing study of disability and handicap in adults following traumatic brain injury. As part of an extensive interview, subjects were asked an open-ended question regarding their current main problems which they thought resulted from their traumatic brain injury. Responses were obtained from 166 adult subjects (119 men and 47 women) whose time postinjury ranged from 9 to 24 years. Categories for responses were subsequently developed. The most commonly reported categories of problems were those relating to movement (39%), cognition (36%), and sensory impairment (31%). Findings suggest that subjects' long-term concerns were related to specific impairments more than to psychosocial, emotional, or behavioral issues. Methodological issues concerning this research are discussed in relation to findings.

Abstract
OBJECTIVES To describe return to work (RTW) for motor vehicle accident (MVA) survivors with mild traumatic brain injury (MTBI) and to examine relationships between RTW and injury severity, cognitive impairment, social interaction, discharge disposition, and sociodemographics. DESIGN Inception cohort assessed within 1 month of injury and at follow-up 6 to 9 months (mean = 7.4) after injury, for comparisons on outcome of RTW. SETTING Tertiary care center in Toronto (time 1); at home for follow-up. PARTICIPANTS Fifty patients with MTBI resulting from MVA who were consecutively admitted during a 20-month period ending April 1994. Thirteen of 63 eligible patients refused consent or were lost to follow-up. Mean age was 31; 62% were men. ELIGIBILITY CRITERIA (1) patients had been working; (2) they had no history of head injury, neurologic disease, or psychiatric illness requiring hospitalization; and (3) they had no catastrophic impairment from accident. MAIN OUTCOME MEASURE Return to work (at premorbid or modified level). RESULTS Of the 42% who returned to work, 12% resumed their premorbid level of employment and 30% returned to modified work. There were significant differences (p<.05) between the groups in level of social interaction, premorbid occupation, and discharge disposition. On one test of cognitive functioning the difference was at p = .06. CONCLUSION Social interaction, jobs with greater decision-making latitude, and discharge home were positively related to RTW for this population. Cognitive impairment within the first month was not a reliable indicator of RTW potential.

Abstract
OBJECTIVE To describe the long-term outcome 5 years after injury of young adults who were 15 to 19 years old at the time of their head injuries. DESIGN A retrospective cohort. The health records of 62 consecutive eligible subjects were abstracted for baseline sociodemographic, health, and injury variables. A telephone interview was administered to assess quality of life, impairment, disability, and handicap. SETTING Canada's largest trauma center, Sunnybrook Health Science Centre, Toronto, Canada. SUBJECTS Of the 58 subjects (94%) who were traced at follow-up, 51 agreed to participate. MAIN OUTCOME MEASURES The Medical Outcomes Study SF-36, Head Injury Symptom Checklist, selected disability measures, Community Integration Questionnaire. RESULTS Of the 8 summary items of the Medical Outcomes Study SF-36, subjects scored lowest on mental health. There were no significant differences between mild and more severely injured groups in all quality of life measures. Subjects classified with mild head injury overall reported more symptoms from the Head Injury Symptom Checklist. Subjects with more severe injuries had lower community integration scores (p < .05). CONCLUSIONS Overall, mental health is an important area of concern at follow-up for all subjects. Adolescents with apparent mild head injury can have disabling symptoms many years after injury.

Abstract
Tiger salamanders have been used in visual science because of the large size of their cells and the ease of preparation and maintenance of in vitro retinal preparations. We have found that salamanders over 27 cm in length show a variety of visual abnormalities. Compared to smaller animals (15-23 cm), large animals exhibited a decrease in visual responses determined by tests of the optomotor reflex. Small animals responded correctly an average of 84.5% of the time in visual testing at three light levels compared to an average of 68.4% for the large animals with the poorest visual performance at the lowest level of illumination. In addition, large animals contained (i) histological degeneration of the outer retina, in particular, loss and disruption of outer segments and abnormalities of the retinal pigmented epithelium, (ii) loss of cells, including photoreceptors, by apoptosis as evaluated with the TUNEL technique, and (iii) an increase in the number of macrophages and lymphocytes within the retina as determined by morphological examination. These histological changes were present in all large animals and all quadrants of their retinas. In contrast, small animals showed virtually no retinal degeneration, no TUNEL-positive cells, and few immune-like cells in the retina. Since large animals are also older animals. the visual changes are age-related. Loss of visual function and histological degeneration in the outer retina also typify aged human eyes. Thus, we propose that large salamanders serve as an animal model for age-related retinal degeneration. In addition to providing a source of aging retina that is readily accessible to experimental manipulation, the salamander provides a pigmented retina with a mixed (2:1, rod:cone) population of photoreceptors, similar to the degeneration-prone parafoveal region of the human eye.

Abstract
OBJECTIVE To determine whether physical function before stroke is an independent predictor of physical function and institutionalization 6 months after discharge from hospital in elderly stroke patients. DESIGN Population-based prospective cohort design where incidence of stroke was monitored from 1982 through 1988. Baseline demographic and health information including prestroke function was collected prospectively. Eligible subjects who had a stroke were interviewed 6 months after discharge from hospital to assess outcomes. SETTING New Haven, Connecticut. PATIENTS Subjects were recruited from an initial sample of 2,812 older adults. Of 79 subjects who survived a first stroke at 6 months postdischarge, complete follow-up data were obtained on 63 subjects. MAIN OUTCOME MEASURE Physical function as measured by the Katz scale and institutionalization. RESULTS Fewer limitations in activities of daily living before stroke were associated with fewer limitation in physical function after stroke controlling for stroke severity and other relevant health and sociodemographic conditions (p < .01). Fewer limitations in gross mobility function before stroke were also independently associated with a lower risk of institutionalization (p < .05). CONCLUSION This study provides useful information in assessing the prognosis of elderly stroke patients upon admission to hospital. It also supports the concept of general frailty being a risk factor for poorer health and institutionalization overall in aged persons. Studies have shown that factors related to physical frailty, such as decline in muscle function, can be reversed. The effect of interventions aimed at improving the physical function of the elderly on stroke incidence, stroke outcomes, and all-cause mortality, however, needs to be determined.

Abstract
In general, coma portends a very poor outcome in ICU patients except when a drug overdose is the cause. Interactions with concurrent diseases and the cause of the comatose state are important variables that modify mortality rates. Recent studies have made it possible to predict irreversibility with a high degree of specificity in many cases. Three approaches show promise for early prediction of poor outcome--multivariate analysis, neurologic findings, and technologic innovations. Multivariate analysis of combinations of clinical conditions common in ICUs appears to have defined some patients whose prognosis is nearly hopeless, empirically. It would seem reasonable to consider withholding or withdrawing life support from these patients so that mere prolongation of death is avoided. Additional studies are needed and are relatively easy to perform with computerized statistical analyses of a readily available database derived from large patient populations in multicenter studies. A second useful approach for predicting irreversibility has arisen from studies using neurologic findings at defined time points after brain injury. The studies of Levy and colleagues exemplify this approach; their data suggest that coma can be declared irreversible with a high degree of confidence in a large subset of patients, delineated by simple sequential neurologic observations. Finally, technologies are evolving that may lead to noninvasive measurements to provide quantitative evidence of irreversible brain damage. Additional clinical studies are needed to validate the predictive value of these approaches to identifying patients who are certain to have a poor ultimate outcome. It then may be possible to predict function and irreversibility of central nervous system injury in individual cases with a high degree of certainty early in the clinical course.

Abstract
The influence of premorbid psychosocial factors on physical function and institutionalization 6 weeks after hospital discharge was studied in elderly stroke patients. The predictor variables of interest were social networks, availability of social support, pre-stroke depression (CES-D), and religiousness. The data were obtained from a prospective longitudinal study based on 2,812 noninstitutionalized individuals aged 65 years and older living in New Haven, Connecticut. Incident stroke cases from this study were followed for post-stroke outcomes. Results from 87 survivors indicated that larger social networks were associated with fewer limitations in physical function, controlling for relevant health and sociodemographic conditions. Larger networks were also associated with a lower risk of institutionalization (p < .05). None of the other psychosocial factors assessed appeared to be related to these outcomes.

Abstract
Neuropsychological and psychiatric evaluations were made of 39 subjects with possible Alzheimer's disease and a history of excessive alcohol consumption (AD + ETOH), who had been abstinent or had drunk minimally for at least three months before evaluation, and 225 patients with probable Alzheimer's disease (PAD) of comparable age, years of education, and baseline global impairment. At baseline, there were no significant differences between the groups in terms of age of onset of dementia, neuropsychological test scores, or current behavioural or psychiatric symptoms. One year later, no differences in rates of decline between 20 abstinent AD + ETOH patients and 88 PAD subjects could be shown. Thus, past heavy alcohol consumption does not appear to modify the presentation of dementia of the Alzheimer's type, nor does it modify progression over a one-year interval.

Abstract
The aim of this paper is to assess the influence of selected psychosocial factors as predictors of stroke incidence in a probability sample of noninstitutionalized elderly. The main psychosocial factor of interest was depression. Marital status, social support, social networks, and religiousness were also assessed as potential antecedent or mediating factors. The data were obtained from a prospective longitudinal study based on 2,812 individuals aged 65 years and over living in New Haven, Connecticut. The incidence of stroke was monitored from the baseline interview in 1982 until December 1988. Depression, measured by the Center for Epidemiologic Studies Depression Scale (CES-D), was measured at baseline as were other predictor variables. Univariate Cox regression analyses revealed that higher CES-D scores were predictive of greater stroke incidence (p < 0.05). More frequent attendance at religious services was associated with lower incidence (p < 0.001). CES-D scores were also correlated with many measures of sociodemographic, health, and physical function factors in our multivariate analysis (p < 0.05). When combined with other significant predictor variables such as age, sex, hypertension, diabetes, physical function, and smoking, neither depression nor religious attendance retained its significance.

Abstract
BACKGROUND AND PURPOSE Our aim in this study was to assess physical function as a predictor of stroke incidence in a probability sample of noninstitutionalized elderly subjects with no previous history of stroke. SUMMARY OF REPORT The data were obtained from a prospective longitudinal study of 2,812 individuals aged 65 years of age and older living in New Haven, Connecticut. Incidence of stroke was monitored from the baseline interview in 1982 until December 1988 (n = 167). Physical function was measured by the Katz scale of activities of daily living and a three-item scale measuring gross mobility function (Rosow scale). Both measures of impairment of function were independently associated with stroke incidence controlling for age, sex, diabetes, hypertension, and angina (p less than 0.001). CONCLUSIONS Our findings suggest that in elderly persons, physical disability is a newly identified risk factor for stroke.

Abstract
Employee assistance programs have grown at a dramatic rate, yet the effectiveness of these programs has been called into question. The purpose of this paper was to assess the effectiveness of employee assistance programs (EAPs) by reviewing recently published EAP evaluations. All studies evaluating EAPs published since 1975 from peer-reviewed journals in the English language were included in this analysis. Each of the articles was assessed in the following areas: (a) program description (subjects, setting, type of intervention, format), (b) evaluation design (research design, variables measured, operational methods), and (c) program outcomes. Results indicate numerous methodological and conceptual weaknesses and issues. These weaknesses included lack of controlled research designs and short time lags between pre- and post-test measures. Other problems identified are missing information regarding subjects, type of intervention, how variables are measured (operational methods), and reliability and validity of evaluation instruments. Due to the aforementioned weaknesses, positive outcomes could not be supported. Recommendations are made for future EAP evaluations.

Abstract
The purpose of the study was to document children's perception of parental exercise, relating these perceptions to (1) the self-reported parents' habits of exercise, and (2) the children's own activity patterns. The subjects were 198 students of both sexes, aged 12 to 14 yr. and enrolled in school Grades 7 to 9. A standard questionnaire assessed their perceptions of parental and personal physical activity. Both parents of each subject also reported their respective levels of habitual physical activity. Congruence between the children's perceptions and the self-reported exercise habits of the opposite-sex parent differed for boys and girls, increasing for boys and decreasing for girls between Grades 7 and 9. No significant associations were observed between the children's perception of parental exercise patterns and their own like habits. This suggests that during adolescence parental influences are minimized by other factors, personal or environmental.

Abstract
The aim of this study was to predict leisure time exercise behavior among a group of 62 lower-limb disabled adults. The theory of reasoned action proposed by Fishbein (Fishbein & Ajzen, 1975) provided a framework for the study. Variables measured included the Fishbein model variables, habit, education, disability type, fitness level, and a 7-day follow-up of exercise behavior. Some 35% of the variance in exercise behavior could be explained; intention was the strongest predictor (.31, p less than .05). In comparison, the ability to predict intentions to exercise by using the other variables was quite poor, with only 7% of the variance explained by habit. None of the Fishbein model variables contributed to this prediction. These results indicated the importance of specific factors, such as the strength of the exercise habit and the cause of disability, on exercise behavior.

The cognitive profile of those who intend to exercise but do not. Public Health Rep 1986; 101:521-6.

Abstract
The purpose of this study was to identify the cognitive profile of people who intend to exercise but fail to carry out this intention. A theoretical framework was adopted to study the attitudinal beliefs of these persons about exercise, their evaluation of the associated consequences, and their normative beliefs and motivation to comply with these norms. Subjects were classified according to the congruence between stated intention and self-reported exercise behavior 2 months later in this way: positive intention and congruent behavior (CONG+, N = 74). positive intention and incongruent behavior (INCONG-, N = 45). negative intention and congruent behavior (CONG-, N = 42). negative intention and incongruent behavior (N = 2, not analyzed). MANOVA analysis indicated little difference between the cognitive profiles of inactive and active positive intenders. Relative to the CONG+ group, the INCONG- group perceived that regular exercise would be "tiring" (P less than 0.001) and "time consuming" (P less than 0.001); they also placed less value on the consequence of "being healthy" (P less than 0.05). Both groups differed from the CONG- group. As would be expected, those with positive intentions to exercise identified more advantages to being physically active. It appears that sedentary positive intenders perceived the exercise behavior as physically demanding and had difficulty in reconciling the time demands of an exercise program with their weekly schedules. This observation suggests that these two beliefs should be considered for the promotion of physical activity as well as the investigation of influential social and environmental variables.
