Estimation of maternal and fetal morbidity in high order cesarean section in Zawia

To assess the maternal and neonatal risk associated with high order cesarean sections, a prospective study was carried out in Zawia hospital, maternity wards. The patient was interviewed in the labor word and performed case sheet filled with specific data. The outcome of 458 cases, 218 women undergoing cesarean section for the third time or more was compared with 240 women sectioned for the second time (P1c/s), the outcome measures were antenatal complication, maternal operative and postoperative morbidity and neonatal prematurity, Apgar scores and the need for intensive care. The antenatal complication is more in group of ≥ P2c/s, placenta previa 9 (3.7%) versus 3 (1.3%) and abruption 8 (3.3%) versus 1 (0.4%). Intraoperative complications found in 17.7% of the cases, 14.2% of the patients with P1c/s comparing with 20.8% among the cases with ≥ 2 Pc. Intra-peritoneal adhesions were more in women with ≥ P2c/s (10.8%) when compared with the women with the history of P1c/s (8.7%). The need for blood transfusion was 5.0% of women with history of ≥ P2c/s compared with 4.1% for women with history of one previous section. The mean duration of operation for patients with P1c/s = 41.5 min and with P2 or more c/s = 47.8 min. Neonatal morbidity rate was 20.9%. There were an increased number of preterm babies in study group of ≥ 2 Pc/s. It is concluded that high order repeat cesarean section carry risk of intraoperative and post operative complication in particularly, placenta previa and acreta and risk of blood transfusion and also neonatal morbidity is increased.
Macro and trace elements in Common Chanterelle (Cantharellus cibarius) mushroom from the European background areas in Poland: Composition, accumulation, dietary exposure and data review for species

This paper gives an up-to-date information on accumulation, occurrence, intake and possible health risks associated with noxious metallic elements (Ag, Cd, Hg, Pb) among mineral constituents (Ag, Al, Ba, Ca, Cd, Co, Cr, Cu, Fe, Hg, K, Mg, Mn, Na, Ni, P, Pb, Rb, Sr and Zn) contained in Common Chanterelle (Cantharellus cibarius) mushrooms, a species subjected to a broad use within the domestic market of Poland and widely exported abroad, and presents a short review of data from the available literature. The tasty values of C. cibarius seem to be more rated than the essential minerals contained in its flesh and nominally taken with 1,000 g of fresh fruiting bodies eaten per capita annually, while the contents of toxic or potentially toxic metals, such as Cd, Pb, Hg and Ag, are much below the tolerance limits.
The Efficacy of Technology Acceptance Model : A Review of Applicable Theoretical Models in Information Technology Researches

This is a review of theoretical models most recently used in Information Technology adoption research. A literature review approach has been adopted. More than 25 literatures were reviewed in the area of information adoption covering the last 30 years. We identified the strengths and weaknesses of each of the theory used. It is found that Technology Acceptance Model is by far the most used to underpin research work in this area follow by Theory of planned behaviour.
Psychologically Adjusted Persons Are Less Aware of How They Are Perceived by Others

Focusing on individual differences, we studied three influences on the accuracy of meta-perceptions of personality: (a) projection, that is, relying on one’s self-perception; (b) normative meta-insight, that is, relying on the perception of the typical person by others; and (c) distinctive meta-insight, that is, relying on others’ perception of one’s unique personality attributes. Using a round-robin design, 52 groups of four acquainted students described themselves, three acquaintances, and their meta-perceptions on the Big-Five factors of personality, and provided self-reports of psychological adjustment. Projection, normative, and distinctive meta-insight contributed uniquely to meta-perception, yet qualified by systematic individual differences: Psychologically adjusted meta-perceivers projected more and relied on distinctive meta-insight less. Moreover, acquaintance raised projection. Thus, psychologically adjusted meta-perceivers were less aware of discrepancies between their self-perceptions and their actual perceptions by others, and the better people knew another person, the more strongly they expected that this other person perceived them like they perceived themselves.
Does the Study Abroad Experience A ect Attitudes Towards Other Nationalities ? ∗

Every year, millions of people relocate to a foreign country for school or work. This research provides evidence of how such international experience shifts preferences and stereotypes related to other nationalities. I use participation in the Erasmus study abroad program as a source of variation in international experience. Students who are ready to participate in the Erasmus program are chosen as a control group for students who have returned from studies abroad. Individuals make decisions in a Trust Game and in a Triple Dictator Game to decompose changes to statistical discrimination from changes to taste-based discrimination. Results show that while students do not di erentiate between partners from Northern and Southern Europe in the Trust Game prior to an Erasmus study abroad, students who have returned from Erasmus studies abroad begin to exhibit less trust towards partners from the South. Behavior towards other nationalities in the Triple Dictator Game is not a ected by the Erasmus study experience. Overall, the results suggest that participants learn about cross-country variation in cooperative behavior while abroad and therefore statistical discrimination increases with international experience.
Expression of cartilage growth plate signalling molecules in chondroblastoma

Chondroblastoma (CB) is a rare benign tumour (<1% of all bone tumours) involving epiphyseal long bones (male : female 1.5 : 1). During development, and in the postnatal period, IHh/PTHrP and FGF signalling molecules control the space and timing of chondrocyte differentiation. Considering the close relationship of CB with the growth plate (age and location), the expression of proteins involved in epiphyseal growth regulation was studied. Twelve cases of CB were retrieved. Immunohistochemistry was performed using antibodies against fibroblast growth factor‐2 (FGF‐2), fibroblast growth factor receptor‐1 (FGFR‐1), FGFR‐3, bcl‐2, p21, parathyroid hormone‐related peptide (PTHrP), and parathyroid hormone‐related peptide receptor (PTHR1). Three observers evaluated haematoxylin and eosin (H&E)‐stained and immunostained slides independently. Semi‐quantitative estimation of the matrix, the type of matrix, and immunostaining was performed. Cellular and matrix‐rich areas were evaluated separately. Diverse amounts and types of matrix were present in different tumours, as well as within individual tumours. Signalling molecules were expressed in 50–100% of the cases. Higher levels of expression were found in cellular areas than in matrix‐rich areas, especially for PTHR1, bcl‐2, and FGFR‐3. CB is an unusual entity affecting specific sites, showing that both IHh/PTHrP and FGF signalling are active. Higher expression was found in cellular than in matrix‐rich areas, as in the proliferating/pre‐hypertrophic growth plate zone in comparison with the hypertrophic/calcifying zone. Previous studies have shown the same molecules to be expressed with a similar pattern in chondrosarcomas. The sum of the evaluated features indicates that CB is a neoplasm originating from a mesenchymal cell committed towards chondrogenesis via active growth plate signalling pathways.

Intakes of selected foods and beverages and the incidence of gastric cancer among the Japanese residents of Hawaii: a prospective study.

BACKGROUND We report on the associations between the intake of certain foods and beverages and the incidence of gastric cancer in a cohort of 11,907 randomly selected Japanese residents of Hawaii (6297 women and 5610 men). METHODS The daily intake of six beverages, cigarettes and alcohol and the weekly frequency of intake of 13 foods and food groups was estimated with a short food frequency questionnaire. Over an average follow-up period of 14.8 years, 108 cases of gastric cancer (44 women, 64 men) were identified via linkage to the Hawaii Tumor Registry. RESULTS In gender-combined proportional hazards analyses, the consumption of fresh fruit seven or more times per week was associated with a significantly reduced risk of gastric cancer, compared to lower levels of consumption (relative hazard (RH): 0.6, 95% confidence interval (CI): 0.4-1.0, P = 0.03). The combined intake of fresh fruit and raw vegetables was inversely associated with the risk of gastric cancer in the total cohort, and among the men (P < 0.05). No significant relationships were found between gastric cancer incidence and the intake of pickled vegetables, miso soup, dried or salted fish, or processed meats among either gender. Compared to non-drinkers, men who drank one cup of coffee per day had a significantly elevated risk of gastric cancer (RH: 2.5, 95% CI: 1.0-6.1, P = 0.05), but there was no evidence of a dose-response relationship. Cigarette smoking and consumption of alcohol were not related to gastric cancer, in analyses restricted to the men. CONCLUSIONS The results related to fruit and vegetable intake are consistent with an anti-nitrosating effect of these foods, while the unexpected association between coffee consumption and gastric cancer is difficult to explain and may represent a chance finding.
Abnormal intestinal permeability in children with autism

We determined the occurrence of gut mucosal damage using the intestinal permeability test in 21 autistic children who had no clinical and laboratory findings consistent with known intestinal disorders. An altered intestinal permeability was found in 9 of the 21 (43%) autistic patients, but in none of the 40 controls. Compared to the controls, these nine patients showed a similar mean mannitol recovery, but a significantly higher mean lactulose recovery (1.64%± 1.43 vs 0.38%±0.14; P < 0.001). We speculate that an altered intestinal permeability could represent a possible mechanism for the increased passage through the gut mucosa of peptides derived from foods with subsequent behavioural abnormalities.
Savage Imaginings: Historical and Contemporary Constructions of Australian Aboriginalities

FROM BOTH Lynette Russell’s memoir and her scholarly study we can draw the same sad conclusion: the gulf of understanding between indigenous and non-indigenous society has led to a damaging, though not deadly, fracture of the Aboriginal community and culture. This conclusion is hardly revelatory but, in partnership, these books do shed light on the subtler effects of systemically racist public policy on private worlds. Savage Imaginings explores the discourses that have shaped public perceptions of ‘the Aborigine’, while A Little Bird Told Me journeys into a concealed family history to uncover the cross-generational secrets and hurt that stemmed from such perceptions. In Savage Imaginings, Russell studies official, academic and popular depictions of Australian indigenous culture, as they appear globally in texts, catalogues and museum displays. She argues that these depictions work to construct a category of ‘Aborigine’ that denies individual identities. Texts such as Walkabout magazine portrayed indigenous culture as homogenous, static and primitive. Russell is interested in uncovering the specific reasons for such portrayals. For example, she argues that, as a publication of the Australian National Travel Association, Walkabout used Aborigines alternately as anthropological subjects and as symbols of the nation’s progress. The lone, anonymous figure standing on an escarpment with one leg half raised represented the precontact age, and showed the world just how far the distant young colony had come. My most treasured possession is a 1975 volume of the Briggs family genealogy. It is a record from a university psychology department that documents my Aboriginal family, following the line from Tasmanian Aborigines to my father. Having been born in 1978, my claim to this heritage is staked by two words, ‘Baby Katy’, scrawled on a scrap of paper that sits next to my father’s name. Despite knowing better, I have always treasured that as ‘evidence’ of my Aboriginal heritage. I am torn by this on two counts: firstly, I subconsciously endorse the position that Aboriginality is genetically determined; secondly, as a means of establishing my sense of place, it highlights the privileging of an external European discourse over my own family’s internal dialogue. Russell’s books address both these issues. The ‘genetic fallacy’ is the historically popular belief that a line of descent was paramount in determining ‘Aboriginality’. The establishment of a genetic link became the crux of identity crises for many Aboriginals. How black is black? While Russell claims that the genetic fallacy has been generally rejected by academia in favour of cultural and socialisation theories, it is a method that still carries weight in sectors of the ‘white’ and even indigenous populace.
Incidence and determinants of Pseudomonas aeruginosa infection among persons with HIV: association with hospital exposure.

BACKGROUND Little information exists on risk factors for Pseudomonas aeruginosa infection in persons with HIV. We assessed the incidence and factors associated with P aeruginosa among persons with HIV enrolled in a large observational cohort study in Los Angeles. METHODS Data were analyzed from 4825 persons aged > or =13 years with HIV infection enrolled from 4 outpatient facilities from 1990 to 1998. The association between P aeruginosa infection and demographic, risk behavior, and clinical factors was assessed. RESULTS P aeruginosa was diagnosed in 72 (1.5%) patients representing a crude incidence rate of 0.74 per 100 person-years. The most frequent site of infection was pulmonary (47%). In multivariate analysis, prior hospitalization (adjusted rate ratio = 7.9, 95% CI, 3.8-16.2), and both dapsone (adjusted rate ratio = 4.0, 95% CI, 2.2-7.4) and trimethoprim-sulfamethoxazole (adjusted rate ratio = 2.5, 95% CI, 1.2-5.3) use were independently associated with higher rates of infection. Increasing days of inpatient stay (P <.01) and decreasing CD4(+) counts (P <.01) were strongly associated with P aeruginosa. Azithromycin use decreased the risk of infection by nearly 70%. CONCLUSION Although the overall observed incidence of P aeruginosa was low, hospital exposure, declining CD4(+) levels, and the use of dapsone or trimethoprim-sulfamethoxazole increased the risk of P aeruginosa disease, and azithromycin use was protective in this population. These findings may assist in the early recognition and diagnosis of persons likely to be at increased risk of P aeruginosa infection.
Flexible lithium-ion planer thin-film battery

Commercialization of wearable electronics requires miniaturized, flexible power sources. Lithium ion battery is a strong candidate as the next generation high performance flexible battery. The development of flexible materials for battery electrodes suffers from the limited material choices. In this work, we present a flexible inorganic lithium-ion battery with no restrictions on the materials used. The battery showed an enhanced normalized capacity of 146 μAh/cm2.
New Strategies for Management of Malnutrition in Peritoneal Dialysis Patients

Malnutrition is not uncommon in peritoneal dialysis (PD) patients; various cross-sectional studies have found signs of malnutrition in 18% – 56% of these patients (1–3). Recent longitudinal studies have examined the evolution of nutritional status in patients treated with PD and there is now compelling evidence that, following an initial improvement, nutritional status gradually declines (3–6). The reason(s) for this are not clear. Johansson et al. (5) showed that, during long-term PD treatment, mean body cell mass remains unchanged during the first year of PD, but there may be a decrease in body cell mass despite maintenance, or even an increase in body energy stores. Likewise, we have found in a prospective study that, whereas body fat mass increases in most patients during 12 months of PD, lean body mass tends to decrease over time (7). Recently, Davies et al. (6) showed that, during long-term PD, malnutrition develops mainly in patients who lose residual renal function. The etiology of malnutrition in PD is complex and may include a number of factors, such as poor food intake, anorexia, nausea and vomiting due to inadequate control of uremic toxicity, delayed gastric emptying, hormonal derangements, inadequate control of acidosis, comorbidity, and inflammation. As with hemodialysis (HD) patients, it is generally believed that suboptimal nutritional status is associated with increased morbidity and mortality in PD patients. The CANUSA study showed that nutritional status is a strong independent predictor of survival (8,9). Likewise, low serum albumin levels have also been reported to be a strong independent predictor of total and cardiovascular mortality in PD patients (10,11). However, in this respect, it should be emphasized that factors other than malnutrition can influence serum albumin concentration — especially inflammatory complications and chronic heart failure — since serum albumin level merely reflects the presence of systemic disease (11,12).

Source-side barrier effects with very high-K dielectrics in 50 nm Si MOSFETs

High permittivity (K) gate insulators are projected for sub-100 nm Si MOSFETs since direct tunneling will likely limit SiO/sub 2/ thicknesses to 1.0-1.5 nm. High-K insulators avoid tunneling, but their larger physical thicknesses introduce subtle capacitive coupling phenomena such as fringing-induced barrier lowering (FIBL) that can compromise off-state leakage. In this study, device simulation examines both on and off-state drain current with very high-K gate insulators and sidewall spacers to reveal new source-side and boundary condition effects. Asymmetric devices help to distinguish the effects. A study of stacked gate insulators demonstrates a 10% increase in drive current achieved with high-K spacers in 50 nm devices.
Anatomic Femoral Tunnels in Posterior Cruciate Ligament Reconstruction

Background: During posterior cruciate ligament (PCL) reconstruction, the placement and orientation of the femoral tunnel is critical to postoperative PCL function. Purpose: To compare the ability of outside-in (OI) versus inside-out (IO) femoral tunnel drilling in placing the femoral tunnel aperture within the anatomic femoral footprint of the PCL, and to evaluate the orientation of the tunnels within the medial femoral condyle. Study Design: Controlled laboratory study. Methods: Ten matched pairs of cadaver knees were randomized such that within each pair, 1 knee underwent arthroscopic OI drilling and the other underwent IO drilling. All knees underwent computed tomography (CT) both pre- and postoperatively with a technique optimized for ligament evaluation (80 keV with maximum mAs). Commercially available third-party software was used to fuse the pre- and postoperative CT scans, allowing comparison of the PCL footprint to the drilled tunnel. The percentage of tunnel aperture contained within the native footprint, as well as the distance from the center of the tunnel aperture to the center of the footprint, were measured. In addition, the orientation of the tunnels in the coronal and axial planes was evaluated. Results: The OI technique placed 70.4% ± 23.7% of the tunnel within the native femoral footprint compared with 79.8% ± 16.7% for the IO technique (P = .32). The OI technique placed the center of the femoral tunnel 4.9 ± 2.2 mm from the center of the native footprint compared to 5.3 ± 2.0 mm for the IO technique (P = .65). The femoral tunnel angle in the coronal plane was 21.0° ± 9.9° for the OI technique and 37.0° ± 10.3° for the IO technique (P = .002). The tunnel angle in the axial plane was 27.3° ± 4.8° for the OI technique and 39.1° ± 11.5° for the IO technique (P = .01). Conclusion: This study demonstrates no difference in the ability of the OI and IO techniques to place the femoral tunnel within the PCL femoral footprint during PCL reconstruction. With the technique parameters used in this study, the IO technique created femoral tunnels with a more vertical and anterior orientation than the OI technique. Clinical Relevance: Either technique can be used to place the femoral tunnel within the anatomic footprint. Consideration should be given to tunnel orientation following each technique, and what effect it has on graft bending angles, as these characteristics may affect graft strain and, ultimately, graft failure. In this regard, the IO technique likely produces gentler graft bending angles.
Association of a promoter variant of the haeme oxygenase-1 gene with hypertension in women

Objective To examine the relationship between the gene for haeme oxygenase (HO)-1 (HMOX-1) and human essential hypertension, because both the acute and systemic induction of HMOX-1 have been suggested to attenuate vascular tone and blood pressure. Methods We screened for sequence variations in HMOX-1 and conducted an association study, using these polymorphisms, in a large cohort (1998 individuals) representing the general Japanese population. Results We sequenced HMOX-1 and found a T(−413)A polymorphism in the promoter region. The frequency of hypertensive individuals and the use of antihypertensive drugs were significantly greater in the AA genotype than in other genotypes among women: 45.5, 34.2, and 35.0% (P = 0.0099) and 23.4, 17.5, and 15.0% (P = 0.038), respectively, for the AA, AT, and TT genotypes, respectively. However, this association was not observed in men. Multiple logistic analyses indicated that the T(−413)A (AA/TA+TT) polymorphism, age, and body mass index affected the occurrence of hypertension in women. The odds ratio of the AA genotype for hypertension in women was 1.59 (P = 0.0058; 95% confidence interval 1.14 to 2.20). A luciferase reporter assay indicated that the A allele-promoter had eight-fold greater activity than the T allele promoter (P < 0.01). Conclusions The AA genotype of HMOX-1 is associated with an increased incidence of hypertension in women. Oestrogen attenuates vasoconstriction by increasing the expression of inducible nitric oxide synthase. As carbon monoxide, which is one of the products of HO-1, can attenuate nitric oxide-induced vasodilatation, a high expression of HO-1 may cause hypertension, especially in women.
Surface Properties of Bifidobacterial Strains of Human Origin

ABSTRACT The adherence of Bifidobacterium strains isolated from infant feces and commercial fermented dairy products to enterocyte-like cells was correlated with the autoagglutination and hemagglutination properties of these organisms. These results allowed us to define two groups: (i) cell-adherent bacteria showing hemagglutination and autoagglutination and (ii) non-cell-adherent, nonhemagglutinating, nonautoagglutinating bacteria. Glass adherence was shown to be nonspecific and was discarded as a criterion for selection of adherent cells. Hydrophobicity appeared to be necessary for adhesion to enterocyte-like cells and autoagglutination. Adhesive strains were highly hydrophobic, and the degree of adherence was slightly dependent on the surface potential. Cells autoagglutinated more when the electrostatic negative charges on the cell surface were shielded by a decrease in the pH from 7 to 2. However, in some strains negative charges at the cell surface were adjuvant to adhesion, thus suggesting that specific chemical interactions occurred. The present results provide a method for preliminary selection of bacteria potentially adherent to epithelial cells by means of autoagglutination.
