Selected AbstractsExercising in Public and Private Environments: Effects on Feeling States in Women with Social Physique AnxietyJOURNAL OF APPLIED BIOBEHAVIORAL RESEARCH, Issue 3-4 2006Brian C. Focht The purpose of this investigation was to examine the influence of acute exercise performed in public and private exercise environments upon feeling states (FS) in 30 women with high social physique anxiety (SPA). A secondary purpose was to examine if perceptions of evaluative threat (EVT) mediated the affective responses to exercise. Multivariate analyses revealed that exercising in the public environment resulted in negative FS responses, whereas exercising in the private environment yielded favorable FS responses to exercise. EVT significantly mediated state anxiety responses to exercise but did not mediate any of the FS responses. The results suggest that the environment influences the FS responses to exercise among women with high SPA and that EVT mediates selected psychological responses to exercise. [source] Late-glacial and Holocene palaeovegetation zonal reconstruction for central and north-central North AmericaJOURNAL OF BIOGEOGRAPHY, Issue 6 2005W. L Strong Abstract Aim, The purpose of this study is to develop palaeovegetation zonation models for central and north-central North America, based on late-Quaternary and Holocene pollen stratigraphic data (n = 246 sites). A secondary purpose was to evaluate an hypothesis (Strong & Hills, 2003) to explain the disjunct distribution of species in western Alberta. Location, Hudson Bay-Lake Michigan to the Rocky Mountains region, north of 36° N to the Arctic Ocean (c. 70° N). Methods, Pollen profiles spanning 40 years of palaeoecological research in North America were extracted from published and unpublished archival sources. Individual profiles were subdivided into 1000-year increments based on the assumption of a constant sedimentation rate between stratigraphic dates (e.g. surface sediments, radiocarbon 14C dates, tephra layers). The pollen composition among profiles was standardized to 54 commonly recognized taxa, with percentage composition within each stratigraphic sample prorated to 100% prior to analysis. Near-surface sediments from these profiles were included as analogues of modern vegetation. Cluster analysis was used as a guide to the classification of 2356 temporal stratigraphic samples, which resulted in the recognition of 16 pollen groups. These groups were summarized in terms of their pollen composition, mapped, and used in combination with terrain information and an ecological knowledge of the study area to construct six physiognomically-based palaeovegetation zonation models at 2000-year intervals from 14,000 to 4000 yr bp (radiocarbon years before present). Results, The 14,000 yr bp model placed Boreal and Cordilleran Forests proximal to the southern glacial front, whereas Arctic tundra dominated the Yukon Territory,Alaska ice-free zone. Pollen and macrofossil evidence suggests that this Boreal Forest zone contained a mixture of coniferous and deciduous tree species. Grassland was postulated immediately south of the forest zone, with its northern extreme near 49° N latitude in the Alberta,Montana border area. Separation of the Laurentide and Cordilleran glacial fronts about 12,000 yr bp initiated the northward advance of Boreal Forests into western Canada. By the end of the Hypsithermal at about 6000 yr bp, Boreal Forests occurred near the Arctic Ocean, and Grassland and Aspen Parkland zones may have extended to 54° N and 59° N latitude in Alberta, respectively. Between 6000 and 4000 yr bp, a 5° and 1° latitudinal southward shift of the northern Boreal Forest and Grassland/Aspen Parkland boundaries occurred, respectively, near their contemporary positions with corresponding expansions of the Subarctic and Arctic zones. Modern Canadian Cordilleran Forests along the eastern slopes of the Rocky Mountains were interpreted as originating from the north-central Montana,south-western Alberta area. Jack pine (Pinus banksiana Lamb.), a common Boreal Forest species, appears to have entered central Canada via the north side of Lake Superior after 11,000 yr bp. Main conclusions, Modern vegetation in central Canada evolved from biomes located in the northern USA during the late-Quaternary. The Boreal Forest biome contained the same arboreal taxa as the modern vegetation, except it lacked jack pine. The proposed regional palaeovegetation models support the hypothesis of Strong & Hills (2003), but new independent palaeoecological data will be needed for a proper evaluation. [source] Use of herbal remedies by diabetic Hispanic women in The southwestern United StatesPHYTOTHERAPY RESEARCH, Issue 4 2006Lane Johnson Abstract Objective: The primary purpose of this study was to examine the use and documentation of herbal remedies used by Hispanic women with Type II diabetes enrolled in two Community Health Centers in the Southwest USA. A secondary purpose was to review the literature on identified herbs to assess their likely effects on diabetes. Design: Open-ended structured interviews were conducted on a convenience sample (n = 23) of participants. Medical and medication charts were reviewed for the interviewed participants, and for a random sample of enrolled Hispanic diabetic patients (n = 81) who were not interviewed. Setting: Two Community Health Centers in the Southwest USA. Participants: Enrolled patient, Hispanic females with Type II diabetes. Intervention: Subjects were interviewed about their use of herbal therapies and supplements. Information collected from medical and pharmaceutical charts included documented use of herbal remedies; standard therapies prescribed and diabetes control (hemoglobin A1C values). For those herbal remedies reported, literature reviews were conducted to determine if there was supporting evidence of harm or efficacy for the stated condition. Main Outcome Measures: Reports of herbal use, and types of remedies used. Results: Among the interviewed participants, 21 of 23 (91%) reported using one or more herbal remedies. Among a random sample of patient medical charts, seven (6.7%) contained documentation of diabetes-specific herbs, and 16 (15.4%) had documented general herb use. A total of 77 different herbal remedies were identified, most of which were contained as part of commercial preparations, and appeared to supplement, rather than replace standard medical therapy for diabetes. Conclusion: Use of herbal therapies is not uncommon among diabetic patients. Many of the herbs reported have potential efficacy in treating diabetes or may result in adverse effects or interactions. In practical use, however, the herbs reported in this study are unlikely to have a significant effect on clinical outcomes in diabetes, either positively or negatively.

[source] Stigma and Self-Concept Among Adolescents Receiving Mental Health TreatmentAMERICAN JOURNAL OF ORTHOPSYCHIATRY, Issue 2 2009Tally Moses PhD Although studies indicate that adolescents diagnosed with mental disorders are stigmatized by the American public, we know very little about the extent to which stigma is experienced by these youth and its effects on their well-being. This cross-sectional study utilizes interviews with 60 adolescents treated in a wraparound program to examine: (a) the extent to which adolescents diagnosed and treated for psychiatric disorders experience mental illness stigma and cope by using secrecy, (b) the extent to which stigmatization is associated with self-concept (self-esteem, mastery, future outlook) and morale (depression), and (c) which clinical and demographic characteristics are associated with perceived stigma. A secondary purpose was to explore the usefulness with adolescents of stigma measures created and adapted primarily from Link's adult stigma scales (Link et al., 1991, 1997). The results support both optimistic and pessimistic interpretations regarding stigma and its effects on adolescents diagnosed and treated for mental disorders. The scales developed for this study demonstrate good internal consistency and construct validity and show promise as tools for further research on stigma as experienced by youth. [source] Additional evidence for the affective dimension of dyspnea in patients with COPD,RESEARCH IN NURSING & HEALTH, Issue 1 2010Virginia Carrieri-Kohlman Abstract The primary purpose of this secondary analysis was to determine whether 103 participants with chronic obstructive pulmonary disease rated the affective dimension of dyspnea (dyspnea-related anxiety and dyspnea-related distress) separately from the sensory dimension (intensity) during baseline exercise testing conducted as part of a randomized clinical trial. A secondary purpose was to determine if dyspnea-related anxiety and distress were rated distinctly different from other measurements of anxiety. At the end of a 6-minute walk and an incremental treadmill test, participant ratings of the magnitude of dyspnea-related anxiety and distress on the Modified Borg Scale were significantly different from their ratings of the intensity of dyspnea. Dyspnea-related anxiety and distress also appeared to be concepts independent from measures of state anxiety, negative affect, and anxiety before a treadmill test. © 2009 Wiley Periodicals, Inc.

Aim., The purpose of this study was to determine if select attributes of a cyclist are associated with seat pressure during stationary bicycling. A secondary purpose was to determine which of the associated attributes were the best predictors of seat pressure and if they were consistent between two different seats. Methods., There were two data collection phases to this correlational study in which 40 males between the ages 20 and 50 years volunteered. For the first phase, select attributes of the cyclist (age, weight, flexibility, experience level, and ischial tuberosity width) were measured. The second phase required participants to ride a stationary cycle ergometer while pelvic tilt angles and seat pressures were measured on two different traditional seats. Main Outcome Measure., The main outcome is the mean and peak bicycle seat interface pressure over the anterior and total seat. Results., Body weight explained up to 50% of the variance in mean total seat pressure (P = 0.001). Regarding peak total pressure, pelvic tilt angle and flexibility explained 43% and 17% of the variance, respectively, for the two seats tested (P = 0.01). Conclusion., These results indicate that predictors of mean seat pressure are not the same for peak pressure. Body weight alone accounted for the most variance in mean pressure whereas pelvic tilt and flexibility accounted for the most variance in peak pressure. These variables related to seat pressure may give some guidance to cyclists and clinicians who intend to prevent or alleviate the symptoms associated with bicycle seat injuries that include erectile dysfunction.

[source] Squamous cell carcinoma of the temporal bone,THE LARYNGOSCOPE, Issue 6 2010Paul W. Gidley MD Abstract Objectives/Hypothesis: To study the survival outcomes of patients with squamous cell carcinoma (SCC) of the temporal bone. A secondary purpose was to evaluate the University of Pittsburgh staging system as a predictor of survival. Study Design: Retrospective review. Methods: We performed a single-institution retrospective review of the medical charts of patients diagnosed with SCC of the temporal bone between 1945 and 2005. We identified the patients' demographic characteristics, presenting symptoms, physical examination findings, tumor histology, disease extent, treatment course, and clinical outcomes. We used the Pittsburgh staging system (2000) to determine the patients' tumor classification and disease state. We then compared the overall and disease-free survival rates between patients with early-stage versus late-stage disease. Results: We identified 124 patients with SCC of the temporal bone. Of these, 71 had incident (untreated) SCC, 26 had recurrent SCC, and 27 had persistent SCC after treatment elsewhere. The 5-year overall survival rate for patients with incident SCC was 38%, and the disease-free survival rate was 60%. The overall survival rate for patients with incident SCC was similar to that for patients with persistent disease and was significantly better than that for patients with recurrent SCC (P = .008). Patients with early-stage tumors (T1 or T2) had longer overall survival than those with late-stage tumors (T3 or T4; P = .004, log-rank). The 5-year overall survival rate was 48% for patients with early-stage disease and 28% for patients with late-stage disease. Furthermore, patients with T1 tumors had significantly longer overall survival than patients with T2 tumors (P = .039) and patients with T3 and T4 tumors (P = .0008). Overall survival (OS) and disease-free interval (DFI) were improved for T2 tumors when radiotherapy was combined with surgery (OS, P = .011; DFI, P = .02). T1 tumors did not benefit in a statistically significant way with combined therapy. T3 and T4 tumors had relatively poor outcomes in spite of combined therapy. Twenty-two patients (31%) experienced a recurrence within 1 year of treatment, whereas only one patient developed recurrence after 1 year. Lymph node metastasis, facial paralysis, or involvement of the carotid artery, jugular foramen, or infratemporal fossa were not significantly associated with overall or disease-free survival. Conclusions: Patients with recurrent SCC of the temporal bone had significantly shorter overall survival and disease-free interval than patients with incident SCC. In addition, patients with early-stage disease (T1 and T2) had significantly longer overall survival and disease-free survival than patients with late-stage tumors. Laryngoscope, 2010 [source] Restraint safety in a residential setting for persons with intellectual disabilitiesBEHAVIORAL INTERVENTIONS, Issue 2 2009David M. Tilli The primary purpose of this study was to estimate the risks associated with the use of emergency personal restraints at a residential facility for persons with intellectual and developmental disabilities. A secondary purpose was to determine if correlates of restraint-related injury could be determined. One in three restraints resulted in an injury, but all of the injuries were minor. In terms of prediction, frequency of aggressive behavior use was the best single predictor of restraint-related injury. Copyright © 2009 John Wiley & Sons, Ltd. [source] The Motivation Behind Serial Sexual Homicide: Is It Sex, Power, and Control, or Anger?,JOURNAL OF FORENSIC SCIENCES, Issue 4 2006Wade C. Myers M.D. ABSTRACT: Controversy exists in the literature and society regarding what motivates serial sexual killers to commit their crimes. Hypotheses range from the seeking of sexual gratification to the achievement of power and control to the expression of anger. The authors provide theoretical, empirical, evolutionary, and physiological support for the argument that serial sexual murderers above all commit their crimes in pursuit of sadistic pleasure. The seeking of power and control over victims is believed to serve the two secondary purposes of heightening sexual arousal and ensuring victim presence for the crime. Anger is not considered a key component of these offenders' motivation due to its inhibitory physiological effect on sexual functioning. On the contrary, criminal investigations into serial sexual killings consistently reveal erotically charged crimes, with sexual motivation expressed either overtly or symbolically. Although anger may be correlated with serial sexual homicide offenders, as it is with criminal offenders in general, it is not causative. The authors further believe serial sexual murderers should be considered sex offenders. A significant proportion of them appear to have paraphilic disorders within the spectrum of sexual sadism. "sexual sadism, homicidal type" is proposed as a diagnostic subtype of sexual sadism applicable to many of these offenders, and a suggested modification of DSM criteria is presented.
