Title Post-stroke Emotional Adjustment: a Modified Social Cognitive Transition Model.
Date March 2012
Journal Neuropsychological Rehabilitation

Patients report a wide variety of emotional responses following stroke. Some individuals find the process of adjusting to their changed circumstances extremely difficult, while others cope well. Predicting and understanding patients' adjustment to stroke therefore poses challenges within rehabilitation settings. While research has revealed some of the variables associated with increased emotional distress (i.e., post-stroke depression) after stroke, a general model of post-stroke emotional adjustment has not yet been put forward. This article proposes that the Social Cognitive Transition model provides a sound theoretical basis upon which to build an understanding of post-stroke adjustment. The essential elements of a Social Cognitive Transition Model for Stroke are summarised, and clinical examples are used to discuss this model. The implications for psychological assessment, formulation and treatment are also discussed.

Title Fatal Gastrointestinal Parasitism in Goats: 31 Cases (2001-2006).
Date December 2007
Journal Journal of the American Veterinary Medical Association

OBJECTIVE: To evaluate signalment, history, clinical and pathologic findings, and seasonal weather patterns in association with fatal gastrointestinal parasitism in goats. DESIGN: Retrospective case series. ANIMALS: 152 goats that were > 1 day of age. PROCEDURES: Characteristics including age and counts of coccidia oocysts and trichostrongyle ova (eggs) per gram of feces (EPG) in goats that died because of gastrointestinal parasitism and goats that died because of other causes were compared. Weather data and annual incidence of caprine fatal gastrointestinal parasitism were investigated. RESULTS: Death was attributed to gastrointestinal parasitism in 31 of 152 (20%) goats (median age, 5 months; range, 1 month to 7 years); deaths were attributed to coccidiosis (n = 7 goats; median age, 4 months; median EPG, 2,225), trichostrongylosis (6 goats; median age, 1.25 years; median EPG, 3,700), or dual infection (18 goats; median age, 6.7 months; median EPG, 8,088 coccidia and 5,475 trichostrongyles). Sudden onset of weakness or death was a common historical finding; diarrhea was evident in 15 goats. Common postmortem findings in these goats included cachexia, tissue pallor, poorly formed feces, and mesenteric lymphadenomegaly. Wet weather in spring and summer was associated with increased annual incidence of fatal gastrointestinal parasitism in goats. CONCLUSIONS AND CLINICAL RELEVANCE: Gastrointestinal parasitism is an important cause of death in goats. Clinical signs may not develop until just prior to death, and diagnosis is achieved via parasitologic evaluation of feces and necropsy. Seasonal weather patterns should be considered on an annual basis when designing parasite control programs for goats.

Title Equine Cutaneous Fungal Granuloma: a Study of 44 Lesions from 34 Horses.
Date December 2006
Journal Veterinary Dermatology

Forty-four nodular and noninvasive cutaneous fungal granulomas were identified in 34 horses over a 14.5-year period. Cutaneous fungal granulomas were most common in young horses (mean age 6.1 +/- 4.2 years; range 1-19 years). There was no apparent breed or sex bias. Granulomas were either single or multiple, and most often occurred in the skin of the head and neck. The characteristic histological finding was a nodular dermal mass with a mean diameter of 7.3 mm (range 2.5-20 mm) and an intact overlying epithelium. Lesions most often exhibited intense lymphocytic inflammation, with admixed pyogranulomatous inflammation associated with a small to moderate number of fungal elements. Causative fungi were both pigmented and nonpigmented organisms of variable morphology. Penetrating plant material was identified in three cases. Granulomas caused by nonpigmented fungi were most common in horses from wet regions. Both pigmented and nonpigmented fungi were found in granulomas from horses in dry regions. Cutaneous fungal granulomas occurred in February through November, with peaks in April and July. No correlation of yearly incidence with annual average temperature or rainfall was detected. This study confirms that equine cutaneous fungal granuloma is relatively common in horses in the Pacific Northwest. Morphology of causative fungi was variable, but the signalment, history, and clinical and overall histological features were very similar. Surgical excision was curative.

Title Age of Menopause and Menopausal Symptoms in Hiv-infected Women.
Date December 2005
Journal Aids Patient Care and Stds

The objective of this study was to examine the median age of menopause, factors associated with postmenopausal status, and the prevalence of menopausal symptoms in HIV-infected women. We surveyed 120 HIV-infected women between 40 and 57 years old who attended an inner city infectious diseases clinic. Ninety-five percent of the women surveyed were African American and almost half of the women (44%) had used methadone, heroin, cocaine, marijuana, or a combination of these drugs within the past 6 months. Eighty-seven percent had smoked cigarettes at least some time during their life and 45% drank alcohol between the ages of 40 and 49 years old. Thirty women were postmenopausal (having no menstrual periods in the previous 12 consecutive months), 31 were perimenopausal (having 1-11 periods within the previous 12 months), and 59 were premenopausal (having 12 or more periods within the previous 12 months). The median age of menopause was 50 years old (95% confidence interval = 49, 53). In a multivariate model, methadone use within the past 6 months was associated with postmenopausal status. We did not find an association between postmenopausal status and body mass index, number of pregnancies, CD4 cell counts, HIV viral load, individual and grouped antiretroviral therapies, cigarette smoking, and current or past oral contraceptive use. In multivariate analysis, postmenopausal status was associated with hot flashes and cocaine use was associated with vaginal dryness.

Title Predictors of Internalizing Symptoms Among Very Low Birth Weight Young Women.
Date December 2005
Journal Journal of Developmental and Behavioral Pediatrics : Jdbp

As part of a longitudinal study of the outcomes of very low birth weight children (<1.5 kg), we sought to examine the perinatal, childhood, and young adult predictors of internalizing symptoms among very low birth weight young women and their normal birth weight controls. The cohort included 125 very low birth weight and 124 normal birth weight 20-year-old subjects. Perinatal, childhood, and young adult predictors were examined via stepwise multivariate analyses. Results revealed very low birth weight to be a significant predictor of parent-reported internalizing symptoms of their daughters but only among white subjects who had mothers with high levels of psychological distress. Additional significant predictors of 20-year internalizing symptoms included child I.Q. and internalizing symptoms at age 8 years and family expressiveness. When the results were analyzed according to the young adult self-report, additional predictors of internalizing symptoms included a history of asthma and exposure to violence. Perinatal risk factors were not found to be predictive of internalizing symptoms at age 20 years. Future studies should prospectively examine social and environmental factors associated with the neonatal intensive care experience that might explain the effect of very low birth weight on later psychopathology.

Title Cytomegalovirus.
Date March 2003
Journal American Family Physician

Cytomegalovirus (CMV) is a prevalent viral pathogen. The majority of persons with acute CMV will experience an inapparent infection. Primary CMV infection will cause up to 7 percent of cases of mononucleosis syndrome and will manifest symptoms almost indistinguishable from those of Epstein-Barr virus-induced mononucleosis. CMV, or heterophil-negative mononucleosis, is best diagnosed using a positive IgM serology. Complications of acute CMV infection in immunocompetent persons are rare, except in newborns. The virus usually is spread through close personal contact; transmission risk can be reduced by following simple hygienic and handwashing techniques. Severe illness can occur after reactivation of the latent virus in immunosuppressed persons. The retina is the most common site of CMV-induced pathology in persons with human immunodeficiency virus infection. Advances in the treatment of human immunodeficiency virus infection with highly active antiretroviral therapy (HAART) have decreased the incidence of CMV retinitis but have resulted in a new set of ophthalmologic complications induced by restoration of immune competency and the pro-inflammatory response of the patient to CMV. If HAART restores the patient's CD4 cell count to above 100 to 150 per mm3 (100 to 150 x 10(6) per L), it may preclude lifelong treatment for CMV retinitis.

Title Epstein-barr Virus-targeted Therapy for Aids-related Primary Lymphoma of the Central Nervous System.
Date November 2000
Journal Lancet

Epstein-Barr virus (EBV) targeted therapeutic strategies for viral associated malignant diseases have received only perfunctory consideration, first, because latent herpesviruses have been intractable to antiviral chemotherapy and, second, because the role EBV has in maintenance of the malignant cell phenotype has been uncertain. Two patients with EBV related primary central nervous system lymphoma (PCNSL) in the setting of advanced AIDS, were treated with low dose hydroxyurea based on in vitro anti-EBV activity. The responses obtained here suggest the promise of antiviral approaches in select cancers.

Title Verbal Memory Deficits in Children with Less Than 750 G Birth Weight.
Date October 2000
Journal Child Neuropsychology : a Journal on Normal and Abnormal Development in Childhood and Adolescence

Numerous studies have documented memory deficits in very low birthweight (VLBW, < 1500 g) children, yet we know little about the nature of these memory problems. To clarify memory sequelae and examine memory deficits in relation to the degree of low birth weight, we administered the California Verbal Learning Test-Children's Version (CVLT-C) to a regional sample of 57 < 750 g birthweight children and to groups of 53 750-1499 g birthweight children and 49 term-born controls. Group comparisons revealed significant differences between the < 750 g birthweight group and term-born children on measures of list learning, delayed recall, and inaccurate recall. In addition, the percentage improvement in correct recognitions relative to long-term delayed recall was greater in the < 750 g group than in the term-born controls. Similar differences were observed between VLBW children with and without abnormal neonatal cerebral ultrasounds (high- and low-risk groups). Differences in learning rate between the VLBW and term-born groups, and between high- and low-risk VLBW children, were evident even when vocabulary skill was covaried or when children with neurosensory deficits or IQ < 80 were excluded from analysis. The findings document deficits in verbal memory in the subset of VLBW children at greatest biological risk, and suggest that acquisition processes are selectively impaired.

Title Neurodevelopment and Predictors of Outcomes of Children with Birth Weights of Less Than 1000 G: 1992-1995.
Date July 2000
Journal Archives of Pediatrics & Adolescent Medicine

OBJECTIVE: To examine the neurosensory and cognitive status of extremely low-birth-weight (ELBW; < 1,000 g) children born from January 1, 1992, through December 31, 1995, and to identify the significant predictors of outcome. DESIGN: An inception cohort of ELBW infants admitted to the neonatal intensive care unit (NICU) and observed to 20 months' corrected age. SETTING: A tertiary level urban NICU and follow-up clinic at a university hospital. POPULATION: Of 333 ELBW infants without major congenital malformations admitted to the NICU, 241 (72%) survived to 20 months' corrected age. We studied 221 children (92%) at a mean of 20 months' corrected age. The mean birth weight was 813 g; mean gestational age, 26.4 weeks. MAIN OUTCOME MEASURES: Assessments of cognitive and neurosensory development. RESULTS: Major neurosensory abnormality was present in 54 children (24%), including 33 (15%) with cerebral palsy, 20 (9%) with deafness, and 2 (1%) with blindness. The mean (+/- SD) Bayley-Mental Developmental Index (MDI) score was 74.7 +/- 17. Ninety-two children (42%) had a subnormal MDI score (<70). Neurodevelopmental impairment (neurosensory abnormality and/or MDI score <70) was present in 105 children (48%). Multiple stepwise logistic regression analysis that considered sex, social risk, birth weight, and neonatal risk factors revealed significant predictors of a subnormal MDI score to be male sex (odds ratio [OR], 2.73; 95% confidence interval [CI], 1.52-4.92), social risk (OR, 1.48; 95% CI, 1.09-2.00), and chronic lung disease (OR, 2.18; 95% CI, 1.20-3.94). Predictors of neurologic abnormality were a severely abnormal finding on cerebral ultrasound (OR, 8.09; 95% CI, 3.69-17.71) and chronic lung disease (OR, 2.46; 95% CI, 1.12-5.40); predictors of deafness were male sex (OR, 2.79; 95% CI, 1.02-7.62), sepsis (OR, 3.15; 95% CI, 1.05-9.48), and jaundice (maximal bilirubin level, >171 micromol/L [>10 mg/dL]) (OR, 4.80; 95% CI, 1.46-15.73). CONCLUSION: There is an urgent need for research into the etiology and prevention of neonatal morbidity.

Title A Tool for Measuring the Asthma Self-management Competency of Families.
Date November 1991
Journal Journal of Psychosomatic Research

A tool for measuring a family's asthma self-management behaviour has been developed for a study examining the relationships of asthma self-management behaviour, knowledge, and psychosocial factors with various indices of morbidity in children with asthma. The tool involves a structured interview which includes three typical situations of asthma self-management (scenarios). Each of the scenarios is divided into graded challenges. A scoring schedule was developed according to the critical incidents of self-management inherent in each situation. This schedule was then applied to the verbatim transcripts of the subjects' responses. These were presented to 380 asthmatic children aged 5-11 yr and their primary caregivers. Inter-rater reliability, inter-rater agreement and test-retest reliability coefficients indicate that the scores obtained are stable across raters and time. Correlations between scores on different scenarios suggest there is a common factor of self-management competency across all scenarios, but families are better at some aspects of self-management than others. The distribution of scores for each scenario is presented. The place of this tool as a means of assessing self-management behaviour is discussed.

Title Calculation of Release Dose for Method B4 of Aami Guidelines for Radiation Sterilization.
Date May 1984
Journal Medical Instrumentation

AAMI has proposed guidelines for establishing minimum processing doses for radiation sterilization of medical devices. The AAMI recommendations do not include computer programs for analysis of the large quantities of data that may be generated during implementation of the dose-setting methodologies. Such utility programs have been developed, using two standard languages--FORTRAN IV and BASIC.

Title Medical, Psychological, and Sociodemographic Factors Associated With Adherence to Cardiac Rehabilitation Programs: A Systematic Review.
Journal The Journal of Cardiovascular Nursing

OBJECTIVES:: Cardiac rehabilitation (CR) programs have been shown to reduce mortality and morbidity rates among coronary heart disease patients, but adherence to these classes has been found to be poor. This review aims to summarize and integrate research findings investigating the possible sociodemographic, medical, and psychological variables that influence patient adherence to CR programs. It also aims to address the methodological failings of past reviews conducted in this area. METHODS:: Several databases were systematically searched for studies published between 1990 and 2009. Studies examining CR program adherence or completion, using data based on participant's actual recorded attendance were included. RESULTS:: Eighteen studies were identified that met inclusion criteria. Low mood, participant's age, and certain cardiac risk factors were found to be most consistently associated with poor adherence to CR. A good understanding of the consequences of heart disease was found to be associated with good adherence. Results were relatively inconsistent across studies because of differences in methods used. CONCLUSIONS:: Certain risk factors for poor adherence to CR should be assessed and monitored by health professionals. Future studies should address the methodological difficulties present in previous research. Recommendations are made for standardizing methods in future research.
