Authors: Fukuoka Yoshimi , Dracup Kathleen , Ohno Miyoshi , Kobayashi Fumio , Hirayama Haruo 
Published: May 2005

Background: The time interval from symptom onset to hospital arrival can guide the decision to start reperfusion for patients with acute myocardial infarction (AMI). Aims: The aims of the study were 1) to examine the consistency and agreement of prehospital delay time between medical record review and structured patient interview and 2) to identify whether symptom severity is an independent predictor of differences in reported prehospital delay between these two data sources. Methods: In this cross-sectional study, a convenience sample of 155 patients with AMI in Japan was recruited. The time and date of symptom onset were obtained from medical record review and a structured patient interview. The interviewer asked about severity of symptoms, using a scale on 0 to 10 scale, with 0 being “no symptom” and 10 being “the most severe symptoms imaginable”. Results: The prehospital delay time from the medical record was significantly shorter than from the structured interview. Perfect agreement of reported prehospital delay time between two data sources was found in 46% of patients. Patients with symptom severity scores of greater than 8 on a 10-point scale were 2.2 times (95% CI: Odds Ratio 1.1 to 5.1) more likely to report different symptom onset time. Conclusions: Prehospital delay time documented in the medical record was shorter than that identified from a structured interview. In addition, the discrepancy between the two data sources may be larger in those patients with severe AMI symptoms.
Fragility—The Price of Renewed Life. Patients Experiences of Open Heart Surgery
Authors: Karlsson Ann-Kristin , Johansson Mats , Lidell Evy 
Published: May 2005

Background: Open heart surgery often implies a threat to life and is associated with fear and anxiety. It is also a strong encroachment on body and integrity and adjusting life afterwards could be difficult. Despite improvements in treatment the patients' reactions appear to be unchanged. Introducing a lifeworld perspective would supply a different kind of knowledge based upon the patients' own experiences coloured by their linguistic usage and bodily expressions. Aim: The aim of this study was to describe patients' experiences of open heart surgery in a lifeworld perspective. Method: Fourteen patients treated with coronary artery bypass surgery and/or heart valve operation were in-depth interviewed in 2003. The phenomenological method was used for the interviews as well as for the analysis. The informants reflected on their experiences of the illness, meetings with health care, family relations and wishes for the future. Findings: The essence of the phenomenon was fragility. Fragility was understood through the following categories: distance, uncertainty, vulnerability, reliance and gratitude. Conclusions: Patients want to be treated as unique individuals. They ask for more dialogues with the staff. Awareness of their supposed lifelong fragility implies that health care staff acquires an open and holistic approach.
BNP as a marker of diastolic dysfunction in the general population: Importance of left ventricular hypertrophy

Published: May 2005

AbstractBNP is a marker of systolic left ventricular dysfunction (LVSD) and heart failure. To assess BNP for the detection of diastolic dysfunction in the general population, we examined 1678 subjects within an age‐ and sex‐stratified survey (MONICA Augsburg). BNP was measured using a commercially available RIA (Shionogi).BNP increased in subjects with diastolic dysfunction (mean 20.3±4.7 pg/ml vs. control 9.6±0.5 pg/ml, p<0.001), but to a lesser extent than in subjects with LV hypertrophy (LVH, mean 37.3±49.1 pg/ml, p<0.001 vs. control) or LVSD (mean 76.2±23.2 pg/ml, p<0.001 vs. control). Individuals with sole diastolic abnormality displayed BNP concentrations at the control level (mean 9.7±1.7 pg/ml). In univariate analysis, age, BMI, systolic blood pressure, left atrial size, LV mass index, diastolic dysfunction and EF displayed a significant correlation with BNP (p<0.001). However, LV mass index displaced diastolic dysfunction as a significant predictor of BNP in multivariate analysis. Upon ROC analysis, sensitivity and specificity for the detection of diastolic dysfunction by BNP were only 61% and 55%, respectively. Nevertheless, a normal BNP test virtually excluded the presence of diastolic dysfunction and concomitant LVH (NPV 99.9%).Increased BNP concentrations in subjects with diastolic dysfunction are strongly related to LVH. Population‐wide screening for diastolic dysfunction with BNP cannot be recommended although a normal BNP test usually excludes diastolic dysfunction and LV hypertrophy.

Authors: Mitchell Ron B. , Kelly James 
Published: May 2005

OBJECTIVETo study the outcome of adenotonsillectomy for obstructive sleep apnea (OSA) in children less than 3 years of age.DESIGN AND SETTINGProspective study at the University of New Mexico Children's Hospital. Children with OSA underwent pre‐ and postoperative full‐night polysomnography (PSG). Scores were compared using a paired t test. A P‐value <0.05 was considered significant.RESULTSThe study population included 20 children. Fifteen (75%) were male. The mean age was 2.2 years (range, 1.1 to 3.0). Sixteen (80%) children had medical comorbidities. Over 25% of children had postoperative complications including laryngospasm and marked desaturations. The mean preoperative respiratory distress index (RDI) was 34.1 and the mean postoperative RDI was 12.2 (P < 0.0001). After surgery, 7 (35%) children had an RDI < 5. Thirteen (65%) had a postoperative RDI ≥ 5 indicating persistent OSA.CONCLUSION AND SIGNIFICANCEChildren under 3 years show significant improvement in RDI after adenotonsillectomy for OSA, but they may develop complications after surgery. Postoperative PSG is recommended for children under 3 years of age to monitor the severity of persistent OSA. EBM rating: B‐2. (Otolaryngol Head Neck Surg 2005;132:681‐684.)
Migration and schizophrenia
Authors: Bhugra Dinesh 
Published: May 2005

Objective: Since the beginning of the human race, individuals have migrated alone or in groups. This process of migration has often been considered to be an aetiological factor in the genesis of many mental disorders. Method: Two studies collecting rates of first onset schizophrenia in Trinidad and in London using the same assessment instruments. Results: The sending countries have low rates of schizophrenia. The impact of migration itself produces high stress but rates of schizophrenia are even higher in the second generation, suggesting that that other social factors may be responsible for the increase if genetic vulnerability is excluded. Conclusion: Individual social factors, such as cultural identity and the impact of racism, are more likely to play a key role in the genesis of schizophrenia.
Relationship between peripheral arterial occlusive disease (PAOD) and chronic Chlamydophila (Chlamydia) pneumoniae infection

Published: May 2005

SummaryWe carried out a meta-analysis of observational case-control studies published before May 2004 to assess the degree of association between Chlamydophila pneumoniae (Cp) infection and PAOD. A search of the Medline database was performed using atherosclerosis and "Chlamyd* pneumoniae" as keywords. Strict criteria were applied for the selection of case studies, which had to be studies of Cp seroprevalence or of Cp detection in patients versus controls. Forty-three published studies that met these criteria were selected. An association between PAOD and Cp was revealed by immunohistochemical analysis (OR=15.4, 95%CI=5.0–46.9) and nested PCR studies of arterial biopsies (OR=4.3, 95%CI=1.8–10), by PCR study of non-arterial samples (OR=2.9, 95%CI=1.2–7.0), by other direct-detection tests (OR=16.7, 95%CI=7.0–39.8), and by ELISA and MIF tests to detect high IgG (OR=2, 95%CI=1.1–3.5 and OR=1.7, 95%CI=1.0–2.9, respectively) and IgA (OR=1.9, 95%CI=1.1–3.4 and OR=1.5, 95%CI=1.1–2.0, respectively) titers. No significant association was found in simple PCR studies of arterial biopsies, MIF tests to detect low IgG titers or IgM, or ELISA studies to detect IgM. According to this review, the association between Cp infection and PAOD depends on the analytical method adopted. Establishing a relationship between Cp and PAOD will require a case-control study with an adequate number of cases and samples that uses a combination of direct and indirect techniques to identify the presence of the bacterium in different types of sample from the same subjects, correlating the results with the activity of the disease.
On the fantastic apparitions of vision by Johannes Müller
Authors: Berrios G. E. 
Published: May 2005

The history of the construction of the concept of hallucination remains biased in favour of the French contribution. Important to this history are the first 30 years of the nineteenth century for it was then that it was decided that hallucinations were: (1) primary disorders of perception; (2) the same class of phenomena, regardless of the sense modality in which they occurred; (3) generated by stimulation of brain regions related to perception and hence were mechanical responses with no semantic or informational import; and (4) medical problems. In 1826 Johannes Müller published a book on the fantastic phenomena of vision. Therein he proposed new rules for the description and explanation of hallucinations. Although published after Purkinje’s books on an analogous theme, and after Esquirol’s entry for the Panckoucke dictionary, Müller’s book served as one of the foundations for the new nineteenth-century speculative physiology and physiopathology of hallucinations. This way of conceptualizing these phenomena was to culminate in the irritation model proposed by Tamburini in the 1880s. This paper justifies the choice of Müller’s book as a classic text, provides biographical data about its author, and places the book in its historical context.
Histories, Logics and Politics: An Interview with Mark Bevir
Authors: Stow Simon 
Published: May 2005

AbstractAlthough he has written extensively on a broad array of topics, Mark Bevir is most famous for his influential and controversial book The Logic of the History of Ideas (Cambridge University Press, 1999). In a wide-ranging interview, Bevir responds to a number of criticisms and mischaracterizations of the book, clarifies his aims in writing it, and identifies his relationship of his postfoundationalism to both analytical and continental philosophy. Additionally, Bevir articulates a hitherto unexpected ethical dimension to the work, suggesting that it seeks to provide for a philosophy of the human sciences that incorporates those capacities for agency and reasoning that make us fully human and are thus deserving of respect. As such, he connects the book to the broader web of moral and political beliefs that underpin his work as a whole.
Development of a Worry Questionnaire for Nursing Home Residents
Authors: Hertzsprung Emerenciana A. , Konnert Candace , Brinker Jaylene 
Published: May 2005

ABSTRACTThis paper describes a new measure, the Worry Questionnaire for Nursing Home Residents (WQNHR), designed to assess the frequency of specific worries. It was administered to 67 residents. Psychometric evaluation showed an average item-to-total correlation of 0.20 (range = 0.15 to 0.58), an internal consistency estimate of 0.79, and a test-re-test reliability coefficient of 0.80. The WQNHR showed good convergent validity with other measures of worry obtained from residents, good discriminant validity with measures of health, but poor discriminant validity with self-ratings of depression. Psychometric results also indicated that the WQNHR performed better for residents with higher cognitive functioning. In addition, a collateral form (WQNHR-C) was administered to family or friends; however, it was not significantly correlated with the WQNHR. Overall, the WQNHR is a promising screening instrument for assessing worry in nursing home residents.
The Overseas Service Veteran At Home Pilot: How Choice of Care May Affect Use of Nursing Home Beds and Waiting Lists
Authors: Pedlar David , Walker John 
Published: May 2005

ABSTRACTIn 1999 Veterans Affairs Canada (VAC) implemented the Overseas Service Veterans (OSV) At Home Pilot Project in response to the problem that a growing number of clients were on waiting lists for beds in long-term care facilities. The At Home pilot offered certain clients on waiting lists, who met nursing-level care and military-service requirements, access to home care and treatment services for which they had previously been ineligible. A review of the pilot showed that a large majority of clients preferred to remain at home, with support, rather than accept a long-term care placement, even when a bed became available. The pilot has helped reduce waiting times for nursing home beds and may have important implications for reducing costs and the demand for long-term care beds.

This article draws on recent thinking innarrative gerontologyto look at three aspects of aging on which a narrative perspective can shed further light. In relation to thetemporalaspects, the notion ofstorytimeis examined. Concerning itspoeticalaspects, the article considers the stages, styles, genres, contexts, and selves of self-storying. Underspiritualaspects, the topics of meaning and identity are explored. A discussion of these aspects may be seen to converge on the theme ofwisdomand the possibility ofwisdom environments.
Variation in an Annual Movement Cycle of Flathead Catfish within and between Two Missouri Watersheds
Authors: Vokoun Jason C. , Rabeni Charles F. 
Published: May 2005

Abstract
Flathead catfish from the main stems of the Grand River and Cuivre River were implanted with 400-d radio transmitters to determine an annual movement cycle. Substantial variation was observed within and between watersheds. Flathead catfish displayed annual movement that consisted of three main periods punctuated by brief migrations. The first, a period of overwintering was followed by migration from wintering areas in early spring, followed in turn by the prespawn/spawning period, which is characterized by increased activity, including longer movements (up to 187.6 km) during spates. After another short migration period came a third period of postspawn summer/fall restricted movement, which was followed by fall migration back to overwintering areas. Within this framework, individual fish displayed at least three variations of this annual pattern. Some individuals entered Grand River and Cuivre River watersheds during the prespawn/spawning period only, returning to the Missouri River or the Mississippi River during summer/fall, overwintering there, and reentering the tributary the following spring. Other individuals entered tributary watersheds for the prespawn/spawning period and remained there for the summer/fall period, returning to the big rivers to overwinter. In the Grand River, all individuals moved downstream (9–45 km) to the Missouri River and overwintered. Finally, some individuals in Cuivre River remained throughout the year, migrating short distances within the river to spawn, feed, and overwinter. The finding that fish were harvested at locations tens of kilometers from the areas where they spent considerable time suggests a larger scale for management than has previously been proposed.
The Substitutability of One Type of Fishing for Another
Authors: Sutton Stephen G. , Ditton Robert B. 
Published: May 2005

Abstract
We investigated the willingness of saltwater anglers in Florida and Texas to substitute other types of fishing for the type of fishing they most preferred. Anglers were asked if there was a suitable substitute for their most preferred species and, if so, what species would provide them with the same satisfaction and enjoyment as their most preferred species at the same cost. Most anglers (86%) reported that other species would provide acceptable substitutes for their preferred species and were able to identify acceptable substitutes from a list of common saltwater species in Texas and Florida. Logistic regression was used to determine the effects of demographic and fishing participation variables on willingness to substitute. Willingness to substitute was positively related to years of education and negatively related to age and the importance placed on trophy-seeking experiences. Also, females were more willing to substitute than males. Results suggest that for some species substitution behavior in response to biologically or managerially imposed constraints on fishing activity could result in increased effort for other species in the saltwater fisheries of Texas and Florida.
Reactions of Silicon Atoms with Cyanogen: Generation and Matrix‐Spectroscopic Identification of Five C2N2Si Isomers
Authors: Maier Günther , Reisenauer Hans Peter 
Published: May 2005

AbstractThe reactions of silicon atoms with cyanogen 12 in an argon matrix at 10 K have been studied. In the initial step a triplet n adduct T‐13 is formed between a silicon atom and 12. The next step needs photochemical activation. Long‐wavelength irradiation yields 3‐cyanoazasilacyclopropenylidene 14, which upon irradiation with 254 nm light is transformed into three isomeric silylenes: dicyanosilylene 15, cyano(isocyano)silylene 16, and di(isocyano)silylene 17. The structural elucidation of all new species is based on comparison of the experimentally obtained IR and UV/Vis spectra with the results of density functional theory calculations.

Synthesis and Some Properties of Aryl‐ and Aryloxy‐Substituted Phthalocyanines and Their Metal Complexes: A Comparison with Porphyrazine and Naphthalocyanine Analogues
Authors: Vagin Sergej , Hanack Michael 
Published: May 2005

AbstractOn the basis of new results from a study with more phthalocyanines, the assignments of some 13C NMR signals of the two phthalocyanines, given in Figure 5 of the original article,[1] must be changed. Thus, signals assigned as 3, 7 and 6 for compound 7b should be assigned as 7, 6 and 3, respectively. Similarly, for compound 7a the assignment of 3 and 7 should be inverted.
Transferrin receptor co‐localizes and interacts with the hemochromatosis factor (HFE) and the divalent metal transporter‐1 (DMT1) in trophoblast cells
Authors: Gruper Yaron , Bar Jacob , Bacharach Eran , Ehrlich Rachel 
Published: May 2005

AbstractIron uptake and storage are tightly regulated to guarantee sufficient iron for essential cellular processes and to prevent the production of damaging free radicals. The placenta is the entry site for iron, which is delivered to the developing embryo. Iron is taken up by syncytiotrophoblast cells and is transported unidirectionally from mother to fetus against a concentration gradient. Several iron transporters and regulators were recently characterized, including DMT1 and ferroportin/Ireg1 that transport iron through membranes, and HFE that regulates TfR‐mediated iron uptake. In this study we demonstrate that in a differentiated choriocarcinoma cell line BeWo, HFE, and TfR are localized mainly in recycling endosomes and a small percentage of these complexes is observed in late endosomes with DMT1 while in trophoblast cells, the level of TfR is significantly lower and it is detected with HFE and DMT1 mainly in late endosomes. Most interestingly, TfR and HFE, as well as TfR and DMT1 interact in placental trophoblast cells. Based on previous and these data we suggest that the level of intracellular iron may regulate both TfR expression (on the post‐transcriptional and the post‐translational levels) and TfR trafficking/transcytosis in polarized cells. © 2005 Wiley‐Liss, Inc.

Published: May 2005

AbstractGram determinants can be used to obtain lower bounds to the Weizsäcker energy for an N‐particle density using expectation values of a wide variety of functions of position. This work focuses on expectation values of radial moments to easily derive many previous bounds and some new bounds and to show that improved bounds are easily obtained by increasing the size of the determinant. © 2005 Wiley Periodicals, Inc.

Principles of antimicrobial prophylaxis
Authors: Burdon Douglas W. 
Published: May 2005

AbstractThe most important principle in surgical antibiotic prophylaxis is to ensure high blood levels of antibiotic at the time of anticipated wound contamination. This is best achieved by intravenous administration commenced at the time of induction of anesthesia. The continued efficacy of prophylaxis depends on the implementation of policies that minimize the opportunities for bacteria to acquire resistance to antibiotics. Prophylaxis should, therefore, be used judiciously and restricted to operations for which it is of established benefit. These are mainly operations in which a viscus colonized by bacteria is opened and in which bacterial contamination is unavoidable. Prophylaxis is also used for certain cardiovascular and orthopedic implant operations in which septic complications are a major threat to a successful outcome and to the life of the patient. The choice of antibiotic should be based on knowledge of the bacterial species likely to contaminate the wound and cause infection. The duration of prophylaxis should be short, and should not be extended beyond the minimum period known to be effective. Controlled trials have established that a single dose of antibiotic is sufficient for many operative procedures and that there is no benefit in prolonging prophylaxis beyond the period when the open wound is exposed to bacterial contamination.
