Evidence of a non-linear influence of patient age on satisfaction with hospital care.

BACKGROUND Patient age is the main socio-demographic factor influencing patient satisfaction with care but the nature of the relationship between age and patient satisfaction is controversial. OBJECTIVE This study aims to clarify whether the association of age with satisfaction is linear or shows some other configuration. METHODS Data were obtained from two different satisfaction studies conducted in 27 short-stay teaching hospitals. Study 1 included 1547 inpatients, who completed the EQS-H questionnaire at the time of discharge. Study 2 included 7624 inpatients interviewed by phone at home after discharge, who answered the SAPHORA questionnaire. On the basis of the results of the exploratory analysis, three models for adjustment of age on satisfaction were compared: a simple linear model, a five-group step function and a linear model with a change in slope. RESULTS The most suitable model for adjusting patient age to satisfaction scores for quality of medical and nursing care, whether for the EQS-H or the SAPHORA scale, was not a linear relationship: patient age was linearly and positively correlated to satisfaction before 65 years and negatively thereafter. Adjustment of patient age to accommodation and premises satisfaction scores proved to be different, closer to a linear relationship. CONCLUSION These results suggest considering the patient age variable as a non-linear factor for adjusting satisfaction scores, in particular in relation to care. Further studies are needed to confirm the evidence of a threshold around 65 years beyond which satisfaction scores for the quality of medical and nursing care decrease.
Postpartum obsessive-compulsive disorder.

OBJECTIVE To synthesize the extant literature on the prevalence, phenomenology, etiology and treatment of postpartum obsessive-compulsive disorder (OCD). A discussion of differential diagnosis between postpartum OCD and other postpartum psychiatric conditions (e.g., depression, psychosis) and nonpostpartum-onset OCD is provided. DATA SOURCES, STUDY SELECTION AND DATA EXTRACTION All studies addressing postpartum OCD between the years 1950 and 2011 were reviewed. Data from all pertinent studies was explored as it related to postpartum OCD. DATA SYNTHESIS Studies were organized based on their empirical technique (e.g., retrospective, prospective), population studied (e.g., clinical OCD, nonclinical populations, males), and etiological or treatment theory (e.g., cognitive-behavioral). CONCLUSION The prevalence, phenomenology, etiology, and treatment of postpartum OCD are reviewed. The limited data on treatment approaches and outcomes for postpartum OCD are highlighted with a discussion of the role of nurses in the prevention and identification of postpartum OCD.
The impact of ethical views on the corporate governance of the firms listed on the Tehran Stock Exchange

The present study seeks to investigate the impact of ethics on the corporate gov ernance. The researc h variables inc lude ethic s and c orporate governance. The ethics of justic e and the ethic s of care are c onsidered as the ethical mec hanisms; whereas the board size, the ownership percentage of institutional inv estors, ownership concentration of the institutional inv estors, board independence, CEO influence, CEO duality and CEO tenure are regarded as the corporate governanc e mec hanisms. The sample is composed of 74 firms listed on the Tehran Stoc k Exchange ov er the y ears from 2007 to 2011 which have been selec ted based on filtering technique. The required data is collec ted through the questionnaire. The researc h hypotheses are developed according to a specific regression model. The findings rev eal that the ethics of care only impacts the board size. Howev er, the ethic s of justice is found to impact the board size, board independence, and the ownership percentage of institutional investors and the ownership concentration of the institutional investors.
Mechanisms of Cation Exchange by Pseudomonas aeruginosa PAO1 and PAO1 wbpL, a Strain with a Truncated Lipopolysaccharide

ABSTRACT The ability of bacterial cells to sequester cations is well recognized, despite the fact that the specific binding sites and mechanistic details of the process are not well understood. To address these questions, the cation-exchange behavior of Pseudomonas aeruginosa PAO1 cells with a truncated lipopolysaccharide (LPS) (PAO1 wbpL) and cells further modified by growth in a magnesium-deficient medium (PAO1 wbpL − Mg2+) were compared with that of wild-type P. aeruginosa PAO1 cells. P. aeruginosa PAO1 cells had a negative surface charge (zeta potential) between pH 11 and 2.2, due to carboxylate groups present in the B-band LPS. The net charge on PAO1 wbpL cells was increasingly positive below pH 3.5, due to the influence of NH3+ groups in the core LPS. The zeta potentials of these cells were also measured in Na+, Ca2+, and La3+ electrolytes. Cells in the La3+ electrolyte had a positive zeta potential at all pH values tested. Growing P. aeruginosa PAO1 wbpL in magnesium-deficient medium (PAO1 wbpL − Mg2+) resulted in an increase in its zeta potential in the pH range from 3.0 to 6.5. In cation-exchange experiments carried out at neutral pH with either P. aeruginosa PAO1 or PAO1 wbpL, the concentration of bound Ca2+ was found to decrease as the pH was reduced from 7.0 to 3.5. At pH 3.5, the bound Mg2+ concentration decreased sharply, revealing the activity of surface sites for cation exchange and their pH dependence. Infrared spectroscopy of attached biofilms suggested that carboxylate and phosphomonoester functional groups within the core LPS are involved in cation exchange.
Nucleotide sequence of the dmsABC operon encoding the anaerobic dimethylsulphoxide reductase of Escherichia coli

The nucleotide sequence of a 6.5 kilobasepair chromosomal DNA fragment encoding the anaerobic dimethylsulphoxide (DMSO) reductase operon of Escherichia coli has been determined. The DMSO reductase structural operon was shown to consist of three open reading frames, namely dmsABC, encoding polypeptides with predicted molecular weights of 87350, 23070, and 30789 Daltons, respectively. The DMS A polypeptide displayed a high degree of amino acid sequence homology with the single‐subunit enzyme, biotin sulphoxide reductase (bisC) and with formate dehydrogenase (fdhF), suggesting that the active site and molybdopterin cofactor binding site that is common to these enzymes is located in the DMS A subunit. A comparison of the predicted N‐terminal amino acids of the dmsA gene product to those of the 82600 subunit of purified DMSO reductase indicated that post‐translational processing of a 16 amino acid peptide at the amino terminus of DMS A had occurred. The DMS B polypeptide contains 16 cysteine residues organized in four clusters, two of which are typical of 4Fe–4S binding domains. The DMS C polypeptide is composed of eight segments of hydrophobic amino acids of appropriate length to cross the cytoplasmic membrane, suggesting that this subunit functions to anchor the enzyme to the membrane.
Zizyphus jujuba protects against ibuprofen-induced nephrotoxicity in rats

Abstract Context. Zizyphus jujuba Mill. (Rhamnaceae) has long been used for the treatment of anxiety and insomnia in Chinese traditional medicine. The edible part is the fruit. Different parts of Z. jujuba possess medicinal properties such as anti-inflammatory, anticancer and antifertility. Objectives: This study evaluated the therapeutic effect of Z. jujuba fruit aqueous extract (ZE) on nephrotoxicity induced by ibuprofen (IBP) in rats. Materials and methods: Male Sprague-Dawley rats were grouped as normal saline (control), ZE (500 mg/kg), IBP (400 mg/kg) and ZE + IBP-treated groups. After five days of oral administration, rats were sacrificed. The protective effect of ZE was evaluated by measuring kidney biomarkers, and histopathological changes of kidney were observed. Kidney antioxidant enzymes such as superoxide dismutase, catalase (CAT), glutathione S-transferase (GST) and lipid peroxidase were investigated. Results: Administration of IBP resulted in a significant increase in urea and creatinine (p < 0.05) and a significant decrease in albumin and total protein (p < 0.05). Damage in glomeruli and proximal convoluted tubules was observed. IBP also increased CAT (p < 0.05) and GST (p < 0.001) activities compared to the control group. Administration of ZE with IBP significantly decreased serum urea and creatinine (p < 0.05) and reduced the severity of kidney damage. There was also a significant increase in the activities of CAT (p < 0.05) and GST (p < 0.001). Discussion and conclusion: These results indicated that Z. jujuba aqueous extract could have a therapeutic role in reducing nephrotoxicity induced by ibuprofen.

This research conducts an empirical study on the influence of customer personality traits and service involvement on customer participation and the influence of customer participation and service involvement on customer satisfaction. Both impact on customer loyalty. Customers of the hair beauty industry are the objects of this study. 299 valid questionnaires were collected and analysed using the LISREL model. The result shows that there’s a significant positive influence of customers’ personality traits on customer participation, a significant positive influence of service involvement on customer participation, a significant positive influence of customer participation on customer satisfaction, and a significant positive influence of customer satisfaction on customer loyalty.
Electron bubbles in liquid helium: Density functional calculations of infrared absorption spectra

Within density functional theory, we have calculated the energy of the transitions from the ground state to the first two excited states in the electron bubbles in liquid helium at pressures from zero to about the solidification pressure. For {sup 4}He at low temperatures, our results are in very good agreement with infrared absorption experiments. Above a temperature of {approx}2 K, we overestimate the energy of the 1s-1p transition. We attribute this to the break down of the Franck-Condon principle due to the presence of helium vapor inside the bubble. Our results indicate that the 1s-2p transition energies are sensitive not only to the size of the electron bubble, but also to its surface thickness. We also present results for the infrared transitions in the case of liquid {sup 3}He, for which we lack experimental data.
Some aspects of fixation with glutaraldehyde. A biochemical and histochemical comparison of the effects of formaldehyde and glutaraldehyde fixation on various enzymes and glycogen, with a note on penetration of glutaraldehyde into liver.

Glutaraldehyde was introduced as a fixative for electron microscopic techniques by Sabatini, Bensch & Barrnett (1963). Although these workers did some rough quantitative estimates of the action of glutaraldehyde on various enzymes, little further cytological work seems to have been done until recently. In fact most interest has been shown previously by the tanning industry, who have demonstrated that glutaraldehyde is a powerful cross-linking substance. The ability of glutaraldehyde to rapidly denature protein has also been exploited by using it as a disinfectant, where it is more efficient than formaldehyde or various phenol derivatives (Snyder & Cheatle, 1965). Recently, comparisons ofaldehyde fixatives with metal fixatives have been published (Ericsson, Saladino & Trump, 1965; Torack, 1965 a; Trump & Ericsson, 1965). It was found that aldehydes fix proteins better than osmium tetroxide. The nature, concentration and pH of the buffer seem more important with metal-containing fixatives than with the aldehydes for obtaining good electron micrographs. The effects of various aldehydes on tissue phosphatases and glycosidases have been systematically studied by Janigan (1964, 1965). The aim of the present work is to extend the basic knowledge of glutaraldehyde fixation. The fixative properties of substances are usually assessed by various simple measurements as outlined by Baker (1960). These include rate of penetration into rat liver blocks and volume changes in pessaries and blocks of liver. As glutaraldehyde is used both in histochemistry and electron microscopy its effect on certain enzymes was studied, both biochemically and histochemically. These effects, under similar conditions, were compared with those of formaldehyde. Further, as it was shown, not unexpectedly, that glutaraldehyde introduced Schiff positivity to tissues fixed in it, this phenomenon was further investigated. A preliminary report of this work has already appeared (Hopwood, 1965).
Roles of Kinins in the Nervous System

The kallikrein-kinin system (KKS) is an endogenous pathway involved in many biological processes. Although primarily related to blood pressure control and inflammation, its activation goes beyond these effects. Neurogenesis and neuroprotection might be stimulated by bradykinin being of great interest for clinical applications following brain injury. This peptide is also an important player in spinal cord injury pathophysiology and recovery, in which bradykinin receptor blockers represent substantial therapeutic potential. Here, we highlight the participation of kinin receptors and especially bradykinin in mediating ischemia pathophysiology in the central and peripheral nervous systems. Moreover, we explore the recent advances on mechanistic and therapeutic targets for biological, pathological, and neural repair processes involving kinins.
Effects of Anonymity and Accountability During Online Peer Assessment

A 2×2 experiment was conducted to determine the effects of anonymity (anonymous vs. named) and peer-accountability (more-accountable vs. less-accountable) on peer over-marking, and on the criticality and quality of peer comments during online peer assessment. Thirty-six graduate students in a Web-based education research methods course were required to critique two published research articles as a part of their course. Peer assessment was carried out on the first critique. Students were randomly assigned to one of the four groups. Peer assessors were randomly assigned three students’ critiques to assess. Peer assessors and the students being assessed were from the same group. Peer assessors assigned a numeric mark and commented on students’ critiques. The four main results were: First, significantly fewer peer assessors overmarked (i.e., assigned a higher mark relative to the instructor) in the anonymous group as compared to the named group (p < .04). Second, peer assessors in the anonymous group provided a significantly higher number of critical comments (i.e., weaknesses) as compared to the named group (p < .01). Third, peer assessors in the named group 304 Wadhwa, Schulz & Mann Copyright © 2006, Idea Group Inc. Copying or distributing in print or electronic forms without written permission of Idea Group Inc. is prohibited. and the more-accountable group made a significantly higher number of quality comments (i.e., cognitive statements indicating strengths and weakness along with reasoned responses and suggestions for improvement), compared to the peer assessors in the anonymous group and the less-accountable group (p < .01). Lastly, the students’ responses to the questionnaire indicated that they found the peer assessment process helpful. This study suggests that in online peer assessment, the anonymity and the degree of peer-accountability affect peer marking and comments.
Health Dynamics Shape Life-Cycle Incomes

This paper studies the relationship between access to credit, demand shocks, and export market adjustments using firm-level panel survey data for 24 economies in the Eastern Europe and Central Asian region. The study finds that domestic shocks to demand have a significant influence on the firm's decision to participate in international markets (extensive margin) and on the firm's share of foreign sales (intensive margin). Foreign shocks to demand only affect the firm's share of foreign sales. Conversely, the role of financial constraints on either the extensive or the intensive margin is more nuanced. The results are robust to various specifications of financial constraints and different estimation methods.
Effects of metal ions on the measurement of alkaline phosphatase activity.

We examined the effects of various metal ions upon alkaline phosphatase (EC 3.1.3.1) from human liver and placenta, individual patient sera, calf intestine, and commercial quality-control materials. Of the metals investigated, Be2+ was the most effective inhibitor of enzyme activity: >50% inhibition at concentrations 5 tmol/L. This inhibition was neithertime-dependent(over30 mm) nor reversible by addition of Mg2+ or Zn2+, or both. The inhibition due to Be2 was purelycompetitivewith4-nitrophenylphosphate foralkaline phosphatase from both human liver and placenta, with K of 0.45 and 0.26 . rmol/L, respectively. These data suggest that the [Be(OH)4]2 anion present at alkaline pH is responsible for this inhibition. FeS+ inhibited enzymes from all sources other than placenta; addition of Mg2 protected against this inhibition. Mn2 inhibited the liver enzyme; addition of Mg2 strengthenedthisinhibitory effect. Other metals inhibitory at 10 mg/L were Co2+, Ni2+,Cd2+, Cr3+, A13+,Mn2+, and Sn2+. Cu2+ was stimulatory only for the quality-control serum. Zn2+ was stimulatory at 15 tmol/L for all enzyme materials, but at 150 mol/L it was inhibitory for all except quality-control materials. These effects are interpreted according to the known metal requirement of the enzyme. Some quality-control materials behave significantly differently from purified human liver or serum enzymes in the presence of trace amounts of metal ions. The inhibition due to Ni2 is time dependent; 4-nitrophenyl phosphate blocksthat inhibition. The presenceofsubstrate retards re-associationof the apoenzyme with metal ions.
Mucosal Fine Structure in Experimental Sinusitis

Rabbit maxillary sinuses were inoculated with Streptococcus pneumoniae and Bacteroides fragilis, and the histologic response in the sinus mucosa was observed over a 12-week period. An increased height of the cylindric cells and hyperplasia of the basal cells were frequent findings irrespective of the pathogen inoculated. The disease was found to influence the character of the secretory product from epithelial secretory cells and to degranulate the subepithelial glands. Ciliary loss was a transitional finding. A reduction in the number of mitochondria, the occurrence of deformed short microvilli, and cytoplasmic blebbing were seen in the cells devoid of normal cilia. It is inferred from this study that pneumococcal sinusitis in rabbits is a self-limiting process, and the mucosal sequelae of the acute infection are persisting goblet cells, slight focal fibrosis, and edema. Inoculation with B fragilis produces a chronic inflammatory process, with infiltration of mononuclear cells, luminal dilatation of the glands exhibiting zymogen granule depletion, and an increased thickness of the whole mucosal layer.
Investigating Information Security Policy Characteristics: Do Quality, Enforcement and Compliance Reduce Organizational Fraud?

Occupational fraud, the use of one’s occupation for personal enrichment through the deliberate misuse or misapplication of the organization’s resources or assets, is a growing concern for all organizations. While the typical organization loses at least 5% of annual revenues to fraud, current methods of detection and prevention are not fully adequate to reduce increasing occurrences. Although information systems are making life easier, they are increasingly being used to perpetrate fraudulent activities, and internal employee security threat is responsible for more information compromise than external threats. The purpose of this research is to examine how information security policy quality and enforcement impacts compliance and mediates organizational fraud levels in a sampling of small to medium-size firms. We will examine if (1) organizations with low (high) quality information security policy experience lower (higher) information security policy compliance; (2) organizations with strong (weak) enforcement of the existing policy experience lower (higher) levels of information security policy compliance; (3) if there is any significant interaction effect between information security policy quality and enforcement and (4) if perceived information security policy compliance is inversely related to reported organizational fraud. Completion of this research will approach the fraud problem from a perspective that has not been studied previously and will inform current findings regarding the potential direct and indirect effects of information security noncompliance on organizational fraud by giving insights into the motivation leading to compliance versus noncompliance decisions encountered by employees in various organizational settings.

Four major publication databases have been used to extract pertinent articles for the review purpose. Four major areas in the literature have been examined: publication activity, integration of brand orientation, research design, and contribution of empirical findings. Based on the synthesis of the current literature, ten future research recommendations are suggested for the advancement of literature on brand orientation. Thus, this study deepens our understanding of the current literature and recommends future research avenues on brand orientation.
Intramedullary Fixation and Bone Grafting for Congenital Pseudarthrosis of the Tibia

Eleven consecutive patients with 12 congenital pseudarthroses of the tibia had intramedullary fixation and autogenous bone grafting as an initial treatment. None of these patients had previous surgeries or other concomitant procedures. The average age of the patients at the time of surgery was 2.5 years (range, 0.5–8.8 years). Four patients achieved initial union after the first index operation; two patients achieved union with no additional procedures, and three patients required an exchange intramedullary fixation for persistent nonunion after refractures that eventually healed. Seven patients did not achieve union after the first index operation; four patients achieved healing after multiple procedures including repeat intramedullary fixation, free vascularized fibular grafting, or both; two patients eventually had below-knee amputations after multiple procedures failed; and one patient did not achieve union of the pseudarthrosis. The important factors leading to failure of union were the distal location of the tibial pseudarthrosis and the presence of concomitant pseudarthrosis of the fibula.
