Yoruba world view and the nature of psychotic illness.

OBJECTIVE The Yoruba are an ethnic group in southern Nigeria. It is said that their world view centers around a continuous battle between forces of good and evil. Adverse events such as illness are due to the malevolence of enemies, using metaphysical means. Remedy often involves corrective metaphysical intervention, either exclusively or in addition to other methods, such as 'western Medicine'. This 'rule' is said to fit mental illness more than any other type of illness, although there is a lack of empirical data on the subject. This study is aimed at identifying elements of a Yoruba world view, and factors relevant to the perception and treatment of psychotic illness. METHOD 500 Yorubas in Lagos were randomly sampled (with a questionnaire), and 100 'home video' films were analyzed. Data were analyzed for: elements of world view; elements that pertain to illness in general; elements that pertain to psychotic illness; how such illness is to be treated. RESULTS The world view has a significant influence on perception of psychotic illness. CONCLUSION It is necessary to understand a people's world view in order to understand (and influence) attitudes towards psychotic illness in themselves and other people.
Software development in a multicultural context: Adaptive and learning organizations

One of the trends in software engineering is globalization. Companies themselves are becoming more international by means of acquisitions and mergers, their business is becoming international, and the staff represents different national cultures. Software development is expert work made in closely collaborating teams. The most natural way to do this kind of work is to implement it in local teams. Distribution of expert work increases the grade of difficulty; an additional grade of difficulty appears if the organizational parts represent different cultural backgrounds. The organizations that are distributed and multicultural must be adaptive. Adaptation can be done in two ways: either to adapt the people to the organization or to adapt the processes of the organization to take into account the differences. In practice, the former seems to be mainly used in big multicultural organizations. In this case, successful globalization also expects adaptation of the organization. There are good practices of the division of labor, management of the organization, project management, etc. that work better than others. There is also a lot of knowledge available concerning the differences between cultures. The aim of this paper is to analyze multicultural Information and Communication Technology (ICT) companies, as adaptive, learning organizations. The focus is on software development work (Software Engineering - SE). The purpose is to report findings based on general cultural studies and reported experiences that seem to lead to successful globalization in the software industry. Some company cases are also described and analyzed. The paper is based on two ongoing research projects at the Tampere University of Technology.
Genetic Influence in Headaches: A Swedish Twin Study

The heritability of liability to self‐reported migraine and nonmigrainous headaches was examined in two large cohorts from the Swedish Twin Registry consisting of 6448 (the older cohort) and 12 884 (the younger cohort) like‐sexed twin pairs. Higher concordance rates were consistently found for lifetime migraine among the monozygotic twins than in the dizygotic twins, as well as for migraine headaches of the recurrent disabling type. In addition, a higher concordance rate was found among the monozygotic twins than in dizygotic twins in a "mixed" group of possible tension‐type or mild migraine headaches (or both). The results of structural equation model‐fitting analyses showed that genetic effects for migraine headaches were stronger for the females (estimates ranging from 49% to 58%) than for the males (39% to 44%) in the two cohorts. Unique nonshared environmental effects were greatest for the “mixed” group in both sexes (estimates ranging from 60% to 69%). The results are discussed in view of similar large‐scale twin studies examining the heritability of liability to migraine.
Assessment of renal hemodynamics and function in pigs with 64-section multidetector CT: comparison with electron-beam CT.

PURPOSE To prospectively evaluate the feasibility of obtaining reliable measurements of renal hemodynamics and function by using 64-section multidetector CT. MATERIALS AND METHODS This study was approved by the Institutional Animal Care and Use Committee. Eight pigs (two with induced unilateral renal artery stenosis) were studied with both electron-beam CT and 64-section multidetector CT at 1-week intervals in randomized order. Both kidneys were scanned repeatedly, without table movement, for about 3 minutes after intravenous (IV) administration of a bolus of contrast medium and again during vasodilator challenge (acetylcholine). Images were reconstructed on each CT console but were analyzed on the same independent workstation. Attenuation changes in the kidneys were plotted as function of time, and time-attenuation curves (TACs) were subsequently analyzed to determine regional perfusion and volume, glomerular filtration rate (GFR), and renal blood flow (RBF). Statistical analysis utilized Student t test, analysis of variance (ANOVA), linear regression, and Bland-Altman analysis. RESULTS TACs obtained with multidetector CT were qualitatively similar to those obtained with electron-beam CT, as were the quantitative values of renal perfusion and function. RBF correlated significantly between the two techniques (RBF(MD) = 0.96 . RBF(EB) mL/min; R = 0.77, P < . 01). GFR(MD) was also similar to GFR(EB) (77.6 +/- 8.3 vs 79.8 +/- 8.8 mL/min, p > .05). Bland-Altman plots showed good agreement between the two techniques. Both techniques similarly detected the differences between stenotic and contralateral kidneys. CONCLUSION The clinical multidetector CT scanner provides reliable measurements of single-kidney hemodynamics and function, which are similar to those obtained with previously validated electron-beam CT.
Risk factors associated with 30-day asthma readmissions

Abstract Objectives: Assess factors that increase the odds of 30-day asthma readmissions to hospitals. Methods: Retrospective chart review between 1/1/2002 to 12/31/2012 of pediatric and adult patients with the primary diagnosis of asthma readmitted within 30 days after the index admission was performed. Patients were identified from billing database for asthma ICD 9 code (493.9). Inclusion criteria were: physician confirmed asthma diagnosis, one or more asthma admissions and accessible medical records. Results: A total of 95 patients with multiple asthma readmissions were included in the final analysis. Thirty-seven patients (39%) were readmitted for asthma within 30 days and 58 patients (61%) had readmission in a 30–365-day period. Demographic characteristics were not significantly different between groups. Bivariate analysis showed that factors associated with higher likelihood of readmissions were a higher frequency of previous admissions, ED visits, inpatient hospitalizations, ICU stays, intubations, chest X-rays, history of chronic sinusitis, gastroesophageal reflux disease, anxiety, and the use of tiotropium or a long-acting beta-agonist (LABA). Multivariable analysis confirmed that prior hospital admissions and a history of GERD are the strongest predictive factors for early asthma readmissions, yet a history of environmental allergies might be a protective factor (p = 0.053). Conclusions: Non-allergic asthma patients with multiple prior admissions, ED visits and inpatient hospitalizations, on multiple medications with history of GERD, sinusitis, and anxiety are more likely to be readmitted within 30 days irrespective of other factors. Patients with these characteristics should be assessed for interventions in an effort to reduce early readmissions.
Life‐span dendritic and spine changes in areas 10 and 18 of human cortex: A quantitative golgi study

Dendritic neuropil is a sensitive indicator of the aging process and may exhibit regional cortical variations. The present study examined regional differences and age‐related changes in the basilar dendrites/spines of supragranular pyramidal cells in human prefrontal (area 10) and secondary occipital (area 18) cortices. Tissue was obtained from the left hemisphere of 26 neurologically normal individuals ranging in age from 14 to 106 years (Mage = 57 ± 22 years; 13 males, 13 females). In tissue prepared by a modified rapid Golgi technique, ten neurons were sampled from each cortical region (N = 520) and were evaluated according to the following parameters: total dendritic length, mean segment length, dendritic segment count, dendritic spine number, and dendritic spine density. The effects of age and Brodmann areas were analyzed with a nested multiple analysis of variance design.
Immunotherapy safety: a prospective multi‐centric monitoring study of biologically standardized therapeutic vaccines for allergic diseases

Background The fear of side‐effects has led to strict regulations preventing a more widespread use of specific immunotherapy (SIT) in some countries, in spite of the low risk of systemic reactions (SRs) reported in well‐controlled studies. The goal of the study was to carry out a prospective and multi‐centric trial to evaluate the safety, risk factors and compliance degree of commercially available SIT.
Acid and alkaline treatments for enhancing the growth of rhizobia in sludge.

Wastewater sludges have been proposed as an effective media for the production of rhizobia. The effect of total suspended solid (TSS) concentrations and pretreatments of sludge on the growth of Sinorhizobium meliloti were investigated. Acid (pH 2.0-6.0 obtained with H2SO4) and alkaline (50-200 mequiv.wt./L of NaOH) treatments were applied to enhance the biodegradability of primary (0.325%-3.2% TSS obtained by dilution of original sample) and secondary (0.2%-0.4% TSS obtained by concentration of original sample) sludges. In primary sludge without pretreatment, the highest cell count (11.10 x 10(9) cfu/mL) was obtained with 1.3% TSS. However, a maximum cell count of 13.00 x 10(9) cfu/mL was reached using an acid treatment of pH 2.0 and a 0.325% TSS concentration. Moreover, the alkaline treatment with 100 mequiv.wt. /L of NaOH and 0.65% TSS increased the cell yield to 21.00 x 10(9) cfu/mL. For secondary sludge without pretreatment, no enhancement of growth was observed while increasing TSS concentration. This may be due to the increase of inhibitory substances, such as heavy metals, and of the Ca and Mg concentrations. As in primary sludge, some acid and alkaline treatments of secondary sludge tend to improve the cell count of S. meliloti. However, the highest value of 9.80 x 10(9) cfu/mL obtained with 0.4% TSS at pH 2.0 was lower than that obtained with primary sludge. It was also observed that S. meliloti grown in treated sludges maintained its capacity to nodulate alfalfa.
Hearts of Hypoxia-inducible Factor Prolyl 4-Hydroxylase-2 Hypomorphic Mice Show Protection against Acute Ischemia-Reperfusion Injury*

Hypoxia-inducible factor (HIF) has a pivotal role in oxygen homeostasis and cardioprotection mediated by ischemic preconditioning. Its stability is regulated by HIF prolyl 4-hydroxylases (HIF-P4Hs), the inhibition of which is regarded as a promising strategy for treating diseases such as anemia and ischemia. We generated a viable Hif-p4h-2 hypomorph mouse line (Hif-p4h-2gt/gt) that expresses decreased amounts of wild-type Hif-p4h-2 mRNA: 8% in the heart; 15% in the skeletal muscle; 34–47% in the kidney, spleen, lung, and bladder; 60% in the brain; and 85% in the liver. These mice have no polycythemia and show no signs of the dilated cardiomyopathy or hyperactive angiogenesis observed in mice with broad spectrum conditional Hif-p4h-2 inactivation. We focused here on the effects of chronic Hif-p4h-2 deficiency in the heart. Hif-1 and Hif-2 were stabilized, and the mRNA levels of glucose transporter-1, several enzymes of glycolysis, pyruvate dehydrogenase kinase 1, angiopoietin-2, and adrenomedullin were increased in the Hif-p4h-2gt/gt hearts. When isolated Hif-p4h-2gt/gt hearts were subjected to ischemia-reperfusion, the recovery of mechanical function and coronary flow rate was significantly better than in wild type, while cumulative release of lactate dehydrogenase reflecting the infarct size was reduced. The preischemic amount of lactate was increased, and the ischemic versus preischemic [CrP]/[Cr] and [ATP] remained at higher levels in Hif-p4h-2gt/gt hearts, indicating enhanced glycolysis and an improved cellular energy state. Our data suggest that chronic stabilization of Hif-1α and Hif-2α by genetic knockdown of Hif-p4h-2 promotes cardioprotection by induction of many genes involved in glucose metabolism, cardiac function, and blood pressure.
EEG abnormalities in early and late onset Alzheimer's disease: understanding heterogeneity

Objective To compare differences in severity and type of electroencephalography (EEG) abnormalities between early and late onset Alzheimer's disease (AD) and to assess the influence of APOE genotype on this association, in order to understand the biological differences in AD according to age at onset Method Of 460 probable AD patients and 336 patients with subjective complaints, serving as controls, EEG and APOE genotype were obtained. Subjects were categorised by age into a younger (≤65 years) and an older group (>65 years), based on age at diagnosis. Severity and type of EEG abnormalities were visually assessed. Severity of EEG abnormalities ranged from normal to slightly abnormal to moderately severe. EEG abnormalities were characterised as only focal abnormalities, only diffuse abnormalities or both focal and diffuse abnormalities. Results Logistic regression revealed that younger AD patients more often had EEG abnormalities, which were more severe, with a predominance of both focal and diffuse abnormalities. In controls, we observed the opposite, as older controls more often had EEG abnormalities than younger controls. Furthermore, APOE ε4 negative AD patients had more severe EEG abnormalities than APOE ε4 positive AD patients, while no such effect was observed in controls. There was no interaction between age at onset and APOE ε4 genotype. Conclusion Early onset and APOE ε4 negative AD patients present with more severe EEG abnormalities than late onset and APOE ε4 positive AD patients. These results suggest that in younger patients, AD manifests with more prominent functional brain changes.
Patient perceptions of injection pain and anxiety: a comparison of NovoFine 32-gauge tip 6mm and Micro Fine Plus 31-gauge 5mm needles.

BACKGROUND Injecting insulin may cause pain and anxiety and lead to suboptimal treatment of diabetes mellitus. The aim of this randomized, open-label, crossover study was to compare two types of needle design and diameter in patients with diabetes injecting insulin. METHODS Patients with diabetes injecting insulin twice daily for at least 3 months were included. A NovoFine (Novo Nordisk, Bagsvërd, Denmark) 32-gauge tip 6mm tapered needle and a Micro Fine Plus (Nippon Becton Dickinson Co. Ltd., Tokyo, Japan) 31-gauge 5mm standard needle were compared. Patients were randomized to use one needle for 1 week, followed by the alternative needle for another week. Before and after each week patients completed a 14-item questionnaire assessing overall satisfaction and usability of the needles. Each item was scored on a visual analog scale from -100 (worst) to +100 (best). RESULTS Thirty patients (24 men, six women) took part in this study: 24 with type 2 diabetes and six with latent autoimmune diabetes in adults. The mean +/- SD for age was 57.8 +/- 7.6 years, for body mass index was 23.0 +/- 3.1 kg/m(2), for duration of diabetes was 15.6 +/- 9.8 years, and for mean glycated hemoglobin was 7.1 +/- 1.1%. Patients were more satisfied with the use of NovoFine 32-gauge tip 6mm needles (P < 0.0001), found the needles less frightening (P < 0.05) and less painful (P < 0.01), and caused less frequent bleeding and bruising (P < 0.001) than Micro Fine Plus 31-gauge 5mm needles. CONCLUSIONS These results suggest that the diameter and design of the needle play an important role in reducing injection pain and needle anxiety, which is particularly important for insulin initiation.
Feature selection for swallowing sounds classification

In recent years swallowing sounds analysis have received great attention for observing the abnormalities in swallowing mechanisms. In this paper a comprehensive set of features were extracted from time and frequency domains characteristics of the signals. Ill features were obtained from different parts of swallowing sounds including initial discrete sounds (IDS), bolus transmission sounds (BTS) and the entire swallowing sounds signal (WHL). Reducing the number of features and selecting a set of most important ones is a crucial step in sketching the signal characteristics, observing the signal variations in classification problems. Therefore, in this study features were examined thoroughly and arranged by maximizing the Mahalanobis distances between normal and dysphagic classes. The results indicate low- and high-frequency components represent the main characteristics of the signals for IDS segment of the swallowing sound, while the medium frequency components play the principal role for BTS segment. Different feature subsets with variable number of features were investigated for classifying normal and dysphagic swallowing sound signals. It was found that the overall performances of the feature subset extracted from WHL was superior to the results of the feature subsets extracted from IDS or BTS individually.
Actin dynamics in development of behavioral sensitization after withdrawal from long-term ethanol administration to mice.

BACKGROUND AND METHODS The present study investigated the role of actin depolymerizing factor (ADF) in the brain of mice after withdrawal from continuous ethanol (EtOH) vapor inhalation for 9 days using C57BL/6J and ADF mutant mice. RESULTS C57BL/6J mice with withdrawal signs 10 hours after withdrawal from EtOH vapor inhalation showed transient and significant enhancement of locomotor activity by a single injection of EtOH (2 g/kg, i.p.) and of EtOH-induced place preference 3 days after withdrawal from EtOH vapor inhalation, suggesting the development of sensitization of locomotion activity to EtOH and of place preference 3 days after withdrawal from EtOH in C57BL/6J mice with EtOH physical dependence. The levels of ADF and G-actin in the ventral tegmental area, including a little bit of surrounding tissues, increased immediately (0 hours), 10 hours, and 3 days after withdrawal from EtOH vapor. F-actin, synaptic vesicle-associated protein 38, and postsynaptic density 95 increased 0 hours and 3 days after withdrawal with their decreases 10 hours after withdrawal from EtOH vapor. An F-actin stabilizing agent phalloidin (3 nmol/mouse/d, i.c.v., once a day) administered daily for 3 days after withdrawal from continuous EtOH vapor inhalation for 9 days significantly suppressed the increase in both EtOH-induced place preference and locomotor activity by a single injection of EtOH 3 days after withdrawal from long-term EtOH vapor inhalation for 9 days. In addition, the changes in behavioral sensitization in ADF mutant mice were significantly weaker than those observed in C57BL/6J mice (wild-type mice for ADF mutant mice). CONCLUSIONS The findings presented here suggest that withdrawal from EtOH physical dependence causes behavioral sensitization to EtOH, which may be, at least in part, mediated by alternation of actin dynamics.
Local axon collaterals of lamina I projection neurons in the spinal cord of young rats

Large, mediolaterally oriented neurons in lamina I of the spinal cord, frequently referred to as marginal cells of Waldeyer, are known to project to supraspinal targets via the anterolateral tract (ALT). Although dendritic organization of lamina I neurons has been extensively studied, little is known about their local axonal morphology and branching. With the help of oblique illumination, we visually identified large lamina I neurons in the isolated lumbar enlargement (L1–L6) of the spinal cord of P14–P20 rats. By using intracellular and cell‐attached biocytin injections, we achieved extensive axonal and dendritic labeling in 77 lamina I cells, 40 of which were identified as ALT projection neurons. In the majority of the cases (n = 28), the main axon of these projection neurons gave rise to one or more thin collaterals on the ipsilateral side. Based on their trajectory and location, these collaterals could be divided into three major categories: dorsal, lateral, and ventral. Lamina I projection neurons had dorsal (n = 5), lateral (n = 8), or ventral (n = 6) collaterals only or a combination of these collateral types (n = 9). Our results suggest that lamina I ALT projection neurons can additionally function as local‐circuit and propriospinal neurons participating in intra‐ and intersegmental spinal cord processing. J.

Lung volume reference values for women and men 65 to 85 years of age.

RATIONALE In elderly subjects, static lung volumes are interpreted using prediction equations derived from primarily younger adult populations. OBJECTIVES To provide reference equations for static lung volumes for European adults 65 to 85 years of age and to compare the predicted values of this sample with those from other studies including middle-aged adults. We compare the lung volumes by plethysmography and helium dilution in elderly subjects. METHODS Reference equations were derived from a randomly selected sample from the general population of 321 healthy never-smoker subjects 65 to 85 years of age. Spirometry and lung volume determinations by plethysmography and multibreath helium equilibration method were performed following the American Thoracic Society/European Respiratory Society recommendations. Reference values and lower and upper limits of normal were derived using a piecewise polynomial model. MEASUREMENTS AND MAIN RESULTS Plethysmography provided higher values than the dilutional method for all lung volumes, with wide limits of agreement. In addition to height, our reference equations confirm the age- and body size dependence of lung volumes in older subjects. Practically all the estimations performed by extrapolating reference equations of middle-aged adults overpredicted the true lung volumes of our healthy elderly volunteers. Middle-aged reference equations classify subjects as being below the total lung capacity lower limit of normal between 17.9 and 62.5% of the women and between 12.5 and 42.2% of the men of the current study. CONCLUSIONS These results underscore the importance of using prediction equations appropriate to the origin, age, and height characteristics of the subjects being studied.
