Prematurity Stereotyping by Mothers of Premature Infants

Previous research has experimentally documented a prematuritystereotype in college students and mothers of full-term infants.The present investigation extends the scope of earlier studiesto mothers of premature infants. Thirty-two mothers of prematureinfants viewed four videotapes of 9-month-old full-term infants,each labeled either full-term or premature and either male orfemale. When infants were labeled premature the mothers perceivedthem as littler, finer featured, weaker, more passive, and slowerthan infants labeled full-term. The mothers also perceived labeledboys as bigger than labeled girls. Differences in stereotypingbetween the mothers in this study and both mothers of full-terminfants and college students are identified and discussed. Resultssuggest that mothers of premature infants expect deficits inpremature infants' physical development but not in prematureinfants' mental or social development. The likely sources andpossible self-fulfilling nature of these biased perceptionsare considered     

Evidence for reduced cerebellar volumes in trichotillomania.

BACKGROUND: Limited knowledge exists regarding the neurobiology of trichotillomania (TTM). Cerebellum (CBM) volumes were explored, given its role in complex, coordinated motor sequences. METHODS: Morphometric magnetic resonance imaging (MRI) scans were obtained for 14 female subjects with DSM-IV diagnoses of TTM and 12 age-, education-, and gender-matched normal control (NC) participants. Parcellation was performed utilizing a recently developed methodology to measure subterritory volumes of the CBM. Regions were defined based on knowledge of the structural and functional subunits of the CBM. RESULTS: As predicted, significant group differences were reported for CBM raw cortical volumes (p = .008) that survived correction for total brain volume (TBV; p = .037) and head circumference (HC; p = .011). A priori and post hoc group raw volume comparisons for CBM subterritories and functional clusters revealed many significant differences. However, most differences failed to withstand correction for total CBM volumes (TCV). Smaller volumes were consistently reported for the TTM versus NC cohorts. Total Massachusetts General Hospital Hair Pulling Scale (MGHHPS) scores were significantly inversely correlated with left primary sensorimotor cluster volumes (p = .008), with smaller volumes associated with more severe TTM symptoms. CONCLUSIONS: These findings implicate the CBM in the neurobiology of TTM, with reduced subterritory volumes reported for the TTM versus NC groups.     

Depression and mental health in neoliberal times: A critical analysis of policy and discourse

Depression has received increasing attention as a significant public health issue over the past ten years, both in Canada and elsewhere in the industrialized west. During the same period, many of the social and economic policies adopted by governments in these jurisdictions have reflected neoliberal goals and orientations. The purpose of this article is to explore the points of contact between these two features of contemporary social and political life in the industrialized west, using the Canadian province of British Columbia as an empirical site. My analysis draws on the Foucauldian literature on governmentality in presenting a close reading of provincial government documents concerned with depression and mental health literacy that have been produced since the election of the Liberal Party to office in British Columbia in 2001. This analysis identifies discourses of “responsibilization” circulating in these documents, within which individuals, families, communities and workplaces – rather than publicly-funded services – appear as key resources in responding to experiences of mental distress. It also points to a number of strategies visible in the documents that work to align the interests of individuals and their practitioners in pursuing particular approaches to treatment with a governing interest in reducing public spending on services and supports. The article concludes by identifying a number of resistive discourses and proposing further research in a range of empirical contexts within which they may be evident.     

Lower urinary tract symptoms in older adults undergoing hip arthroplasty: a feasibility study.

PURPOSE: We undertook a feasibility study to explore the prevalence of preoperative and postoperative lower urinary tract symptoms (LUTS) in older adults undergoing elective hip arthroplasty and to determine whether a larger prospective study was warranted. METHOD: Subjects awaiting elective hip arthroplasty were recruited preoperatively from an orthopedic office and preadmission clinic at 1 university-affiliated hospital. LUTS and related quality of life were measured prehospitalization and 6 weeks postoperatively using the American Urological Association Symptom Index and quality-of-life score. Postvoid residual urine and the 24-hour pad test were used to assess bladder emptying and continence status. RESULTS: Sixteen participants (9 males, 7 females, mean age 74 years) completed the study. Preoperatively, 15 participants reported at least 1 symptom and none had discussed these with a healthcare professional. The most common LUTS were nocturia, frequency, and urgency. Postoperatively, all reported symptoms, with 8 (53%) experiencing increased symptoms with a negative impact on quality of life for 3. Recruitment was a major barrier in conducting the study and would need to be taken into account in further studies of the topic. CONCLUSION: Despite recruitment issues, we suggest larger studies of LUTS in older adults undergoing surgery are warranted to further understand potential problems and risks in transition from hospital to home. Future studies should include identification of potential reasons for increased LUTS, including urinary tract infection.     

A case-controlled study of altered visual art production in Alzheimer's and FTLD.

OBJECTIVE: To characterize dementia-induced changes in visual art production. BACKGROUND: Although case studies show altered visual artistic production in some patients with neurodegenerative disease, no case-controlled studies have quantified this phenomenon across groups of patients. METHOD: Forty-nine subjects [18 Alzheimer disease, 9 frontotemporal dementia (FTD), 9 semantic dementia (SD), 15 healthy older controls (NC)] underwent formal neuropsychologic testing of visuospatial, perceptual, and creative functioning, and produced 4 drawings. Subjective elements of drawings were rated by an expert panel that was blind to diagnosis. RESULTS: Despite equal performance on standard visuospatial tests, dementia groups produced distinct patterns of artistic features that were significantly different from NCs. FTDs used more disordered composition and less active mark-making (P<0.05). Both FTDs and SDs drawings were rated as more bizarre and demonstrated more facial distortion than NCs (P<0.05). Also, SDs drastically failed a standardized test of divergent creativity. Alzheimer disease artwork was more similar to controls than to FTDs or SDs, but showed a more muted color palette (P<0.05) and trends toward including fewer details, less ordered compositions, and occasional facial distortion. CONCLUSIONS: These group differences in artistic style likely resulted from disease-specific focal neurodegeneration, and elucidate the contributions of particular brain regions to the production of visual art.     

Measurement of leptin in dried blood spot samples.

Leptin is important in a wide range of physiological processes, but logistical constraints associated with venipuncture blood collection have limited research on leptin in diverse, community-based settings. The aim of this short report is to present and validate an enzyme immunoassay method for quantifying leptin in samples of capillary whole blood collected from a simple finger prick and dried on filter paper. The method was evaluated through analysis of precision, reliability, stability, and comparisons with matched plasma and blood spot samples. We report acceptable levels of assay precision and reliability, and good agreement between results obtained from matched plasma and blood spot samples (r = 0.976, P < 0.001). Leptin concentrations begin to deteriorate after only 3 days at room temperature. Thus, care should be taken to refrigerate or freeze samples promptly. The relative ease of blood spot sample collection may facilitate research on leptin in a wider range of cultural and ecological settings.
