Drug Use Profile, 2011

Historically, alcohol is the most prevalent substance of use and abuse by adults in Iowa. Research from the Behavioral Risk Factor Surveillance System compiled by the federal Centers for Disease Control and Prevention indicates that almost six of every ten adult Iowans are classified as current drinkers of alcoholic beverages. Further, one in five adult Iowans is classified as a binge drinker of alcoholic beverages, a classification indicative of abuse of, or addiction to, the substance.

Depth profile of uncompensated spins in an exchange bias system

We have used the unique spatial sensitivity of polarized neutron and soft x-ray beams in reflection geometry to measure the depth dependence of magnetization across the interface between a ferromagnet and an antiferromagnet. The net uncompensated magnetization near the interface responds to applied field, while uncompensated spins in the antiferromagnet bulk are pinned, thus providing a means to establish exchange bias.

Board examination for anatomical pathology in Switzerland: two intense days to verify professional competence.

About 15 years ago, the Swiss Society of Pathology has developed and implemented a board examination in anatomical pathology. We describe herein the contents covered by this 2-day exam (autopsy pathology, cytology, histopathology, molecular pathology, and basic knowledge about mechanisms of disease) and its exact modalities, sketch a brief history of the exam, and finish with a concise discussion about the possible objectives and putative benefits weighed against the hardship that it imposes on the candidates.

Blood profile during and after hemoglobin substitute administration.

The in vivo effects of Diaspirin Crosslinked Hemoglobin (DCLHb, Baxter Healthcare Corp.) on hematology and biochemistry are unknown. This study includes 6 calves (71.2+/-1.3 kg). In each animal a total of 2 litres of blood was exchanged for the same amount of hydroxylethyl starch (Haes, Fresenius) (n=3) or DCLHb (n=3), which is equivalent to 28cc/kg of blood substitute, over a period of 5 hours. The animals were allowed to survive 7 days. Blood samples were taken hourly during the perfusion protocol, at postoperative day (POD) 1, 2 and 7. ANOVA test was used for repeated measurements. Blood cell profiles were similar in both groups. Peak methemoglobinemia was 4.2% in the DCLHb group. Osmolarity was significantly higher in the DCLHb group with the greatest difference at POD 1 and 2. Postmortem analysis of the major organs did not show any sign of hemoglobin deposit in the DCLHb group. In the given setup DCLHb can be administered in a large quantity with good hematological tolerance and without any deposits in major organs. A prolonged plasma expander effect was observed.

Effect of manganese chloride on the neurochemical profile of the rat hypothalamus.

Manganese (Mn(2+))-enhanced magnetic resonance imaging studies of the neuronal pathways of the hypothalamus showed that information about the regulation of food intake and energy balance circulate through specific hypothalamic nuclei. The dehydration-induced anorexia (DIA) model demonstrated to be appropriate for studying the hypothalamus with Mn(2+)-enhanced magnetic resonance imaging. Manganese is involved in the normal functioning of a variety of physiological processes and is associated with enzymes contributing to neurotransmitter synthesis and metabolism. It also induces psychiatric and motor disturbances. The molecular mechanisms by which Mn(2+) produces alterations of the hypothalamic physiological processes are not well understood. (1)H-magnetic resonance spectroscopy measurements of the rodent hypothalamus are challenging due to the distant location of the hypothalamus resulting in limited measurement sensitivity. The present study proposed to investigate the effects of Mn(2+) on the neurochemical profile of the hypothalamus in normal, DIA, and overnight fasted female rats at 14.1 T. Results provide evidence that γ-aminobutyric acid has an essential role in the maintenance of energy homeostasis in the hypothalamus but is not condition specific. On the contrary, glutamine, glutamate, and taurine appear to respond more accurately to Mn(2+) exposure. An increase in glutamine levels could also be a characteristic response of the hypothalamus to DIA.

Severely presenting strokes : profile & outcome

Etat des connaissances: Les Accidents vasculaires cérébraux (AVC) sévères sont une cause importante de mortalité et de handicap en Suisse. Les buts de cette étude sont de déterminer les caractéristiques des patients avec un AVC à présentation initiale sévère "severely presenting", ainsi que d'identifier les facteurs prédicteurs en phase aigüe et subaigüe d'un devenir favorable chez ces patients. Methodologie: En utilisant le registre des AVC "Acute STroke Registry and Analysis of Lausanne (ASTRAL), nous avons comparé tous les patients avec un AVC "à présentation sévère", defini comme un score National Institute of Health Stroke Scale (NIHSS) > 20 à l'admission aux urgences, avec tous les autres patients du registre. Dans une analyse statistique multivariée, les associations avec les caractéristiques démographiques, cliniques, pathophysiologiques, métaboliques et radiologiques des patients on été déterminées. Dans un deuxième temps, nous avons analysé les facteurs prédicteurs d'un devenir favorable à 3 mois (modified Rankin scale (mRS) <3) dans ce groupe d'AVC à présentation sévère. Resultats: Parmi les 1 '915 patients consécutifs, 243 (12.7%) présentaient un AVC rejoignant la définition de sévère. Ceux-cis étaient associés de manière significative avec un méchanisme ischémique cardio-embolique (OR=1.74 / 95% CI 1.19 - 2.54), un début inconnu de la Symptomatologie (OR=2.35 / 95% CI 1.14 - 4.83), avaient plus de trouvailles d'origine ischémique aigüe lors de l'imagerie dJentrée (la majorité sont des CT-scan, OR=2.65 / 95% CI 1.79 - 3.92), plus d'occlusions dans l'imagerie vasculaire d'admission (OR=27.01 / 95% CI 11.5 - 62.9), moins d'anciens infarctus cérébraux sur l'imagerie (OR=0.43 / 95% 0.26¬0.72), un taux d'haemoglobine plus bas en g/1 (OR=0.97 / 95% CI 0.96 - 0.99), un taux de leucocytes plus élevé par 1000 cells/1 (OR=1.05 / 95%CI 1.00 - 1.11). parmi les 68 (28%) patients avec un devenir favorable malgré un AVC initialement sévère, leur évolution favorable à été associée avec un âge plus jeune (OR=0.94 / 95% CI 0.92 - 0.97), la présence d'évenements cérébrovasculaires antécédants (OR=3.00 / 95% CI 1.01 - 8.97), un traitement hypolipémiant déjà présent (OR= 3.82 / 95% CI 1.34 - 10.90), une température corporelle d'admission plus basse (0R=0.43 1 95% CI 0.23 - 0.78), une concentration subaigüe de glucose plus basse (OR=0.74 1 95% CI 0.56 - 0.97), et une recanalisation spontanée ou par thrombolyse à 24h (OR= 4.51 1 95%CI 1.96- 10.41). Conclusion: les AVC à présentation initiale severe sont associés à des facteurs prédicteurs cliniques, radiologiques, et métaboliques multiples, dont certains sont modifiables. Les facteurs prédicteurs des 28% de patients avec un devenir favorable en dépit d'un AVC intitialement sévère sont un pré-traitement par hypolipémiants, une temperature corporelle plus basse à l'admission, une glycémie plus basse à 24heures et la recanalisation artérielle.

The personality profile of borderline personality disordered patients using the five-factor model of personality

The purpose of this ex post facto study is to analyze the personality profile of outpatients who met criteria for borderline personality disorder according to the Five-Factor Model of personality. All patients (N = 52) completed the International Personality Disorder Examination (IPDE) Screening Questionnaire, the Big Five Questionnaire (BFQ), the Beck Depression Inventory (BDI), and the Beck Hopelessness Scale (BHS). The results show a high comorbidity with other DSM-IV-TR Axis II disorders, in particular with those from Cluster C. The BFQ average score indicates that the outpatients who met borderline criteria score lower than controls on all five dimensions, and especially on emotional stability. Correlations were computed between the BFQ and the IPDE scales in our sample. These results suggest that specific personality profile are linked to different comorbidity patterns. More than a half of our sample has clinically significant scores on Beck's scales. Surprisingly, depression and hopelessness are neither correlated with the borderline scale, nor have an effect in the relationship between personality and personality disorders.

State of Iowa 1998 Inmate Profile, 1999

This report was compiled at the request of the Department of Corrections. The first section describes Iowa’s prison inmate population at mid-year. The first section also provides a comparison of the mid-year 1998 prison population with the population one year ago, and five years ago. Included is analysis of sex, race/ethnicity, age categories, life terms, mandatory minimum sentences, number of sentences per inmate, and offense type. Following the statewide section are Facility Profiles that examine each Department of Corrections institution. The facility profiles cover the same types of information as the statewide report for mid-year 1998, except that committing county and judicial district, Board of Parole risk scores and sex are excluded.

Medical residents' feedback on needs and acquired skills following a short course on cross-cultural competence

Objectives The purpose of this study is to assess short and long term changes in knowledge, attitudes, and skills among medical residents following a short course on cultural competency and to explore their perspectives on the experience. Methods Eighteen medical residents went through a short training programme comprised of two seminars lasting 30' and 60' respectively over two days. Three months later, we conducted three focus groups, with 17 residents to explore their thoughts, perspectives and feedback about the course. To measure changes over time, we carried out a quantitative sequential survey before the seminars, three days after, and three months later using the Multicultural Assessment Questionnaire. Results Residents expressed a wide variety of perspectives on the main themes related to the content of the training - culture, trialogue, stereotypes, status, epidemiology, history and geopolitics - and related to its organization - relevance, volume, timing, target audience, training tools, and working material. Using the MAQ, we observed a higher global performance score (n=16) at three days (median=38) compared to results before the training (median=33) revealing a median difference of 5.5 points (z=2.4, p=0.015). This difference was still present at three months (∆=4.5, z=2.4, p=0.018), mainly due to knowledge acquisition (∆=3) rather than attitudes (∆=0) or skills (∆=1). Conclusions Cross-cultural competence training not only brings awareness of multicultural issues but also helps participants understand their own cultures, perception of others and preconceived ideas. Physicians' education should however also focus on improving implementation of acquired knowledge in cross-cultural competence.
