Dietary Approaches in the Management of Diabetic Patients with Kidney Disease

Chronic kidney disease (CKD) is one of the most prevalent complications of diabetes, and patients with diabetic kidney disease (DKD) have a substantially higher risk of cardiovascular disease and death compared to their non-diabetic CKD counterparts. In addition to pharmacologic management strategies, nutritional and dietary interventions in DKD are an essential aspect of management with the potential for ameliorating kidney function decline and preventing the development of other end-organ complications. Among DKD patients with non-dialysis dependent CKD, expert panels recommend lower dietary protein intake of 0.8 g/kg of body weight/day, while higher dietary protein intake (>1.2 g/kg of body weight/day) is advised among diabetic end-stage renal disease patients receiving maintenance dialysis to counteract protein catabolism, dialysate amino acid and protein losses, and protein-energy wasting. Carbohydrates from sugars should be limited to less than 10% of energy intake, and it is also suggested that higher polyunsaturated and monounsaturated fat consumption in lieu of saturated fatty acids, trans-fat, and cholesterol are associated with more favorable outcomes. While guidelines recommend dietary sodium restriction to less than 1.5–2.3 g/day, excessively low sodium intake may be associated with hyponatremia as well as impaired glucose metabolism and insulin sensitivity. As patients with advanced DKD progressing to end-stage renal disease may be prone to the “burnt-out diabetes” phenomenon (i.e., spontaneous resolution of hypoglycemia and frequent hypoglycemic episodes), further studies in this population are particularly needed to determine the safety and efficacy of dietary restrictions in this population.
Balancing between bleeding and thromboembolism after percutaneous coronary intervention in patients with atrial fibrillation. Could triple anticoagulant therapy be a solution?

Introduction Atrial fibrillation (AF) has nowadays become a common disease as it comes along with medical procedures propagation in the ageing population with coexistent diseases. Hence a need for use of combined anticoagulant and antithrombotic therapy has arisen. According to the 2010 ESC guidelines on myocardial revascularization, short-term triple antithrombotic therapy after percutaneous coronary intervention (PCI) should be given if compelling indications exist. Aim To assess bleeding and thromboembolic events depending on the antithrombotic regimen in short- and long-term follow-up in patients with AF after PCI with stent implantation. Material and methods A 12-month prospective, non-randomized registry was conducted in the 3rd Department of Cardiology in the Upper Silesian Medical Center in Katowice from October 2008 to April 2011. One hundred and four patients in two groups – on triple therapy (TT; aspirin + clopidogrel + vitamin K antagonists (VKA; warfarin or acenocoumarol) n = 44) and on dual therapy (DT; aspirin + clopidogrel; n = 60) – were assessed 30 days and 12 months after angioplasty. Results All bleeding events occurred more often in the triple anticoagulated group in 30 days (TT 20.5% vs. DT 6.7%; p = 0.03) and after 12 months (TT 38.9% vs. DT 17.2%, p = 0.09). The difference in major bleeding events was not significant after 30 days (TT 9.1% vs. DT 3.3%; p = NS) or 12 months (TT 11.1% vs. DT 6.9%; p = NS). Thromboembolic events after 30 days (DT 5.0% vs. TT 2.3%) and 12 months (TT 11.1% vs. DT 3.4%) were comparable. The percentage of deaths after 30 days (DT 1.7% vs. TT 0.0%, p = NS) increased after 12 months (DT 13.8% vs. TT 0.0%, p = 0.09). Conclusions Significantly higher risk of bleeding on TT becomes blurred by a tendency to increased mortality in patients on DT.
The causal role of breakfast in energy balance and health: a randomized controlled trial in lean adults

Background: Popular beliefs that breakfast is the most important meal of the day are grounded in cross-sectional observations that link breakfast to health, the causal nature of which remains to be explored under real-life conditions. Objective: The aim was to conduct a randomized controlled trial examining causal links between breakfast habits and all components of energy balance in free-living humans. Design: The Bath Breakfast Project is a randomized controlled trial with repeated-measures at baseline and follow-up in a cohort in southwest England aged 21–60 y with dual-energy X-ray absorptiometry–derived fat mass indexes ≤11 kg/m2 in women (n = 21) and ≤7.5 kg/m2 in men (n = 12). Components of energy balance (resting metabolic rate, physical activity thermogenesis, energy intake) and 24-h glycemic responses were measured under free-living conditions with random allocation to daily breakfast (≥700 kcal before 1100) or extended fasting (0 kcal until 1200) for 6 wk, with baseline and follow-up measures of health markers (eg, hematology/biopsies). Results: Contrary to popular belief, there was no metabolic adaptation to breakfast (eg, resting metabolic rate stable within 11 kcal/d), with limited subsequent suppression of appetite (energy intake remained 539 kcal/d greater than after fasting; 95% CI: 157, 920 kcal/d). Rather, physical activity thermogenesis was markedly higher with breakfast than with fasting (442 kcal/d; 95% CI: 34, 851 kcal/d). Body mass and adiposity did not differ between treatments at baseline or follow-up and neither did adipose tissue glucose uptake or systemic indexes of cardiovascular health. Continuously measured glycemia was more variable during the afternoon and evening with fasting than with breakfast by the final week of the intervention (CV: 3.9%; 95% CI: 0.1%, 7.8%). Conclusions: Daily breakfast is causally linked to higher physical activity thermogenesis in lean adults, with greater overall dietary energy intake but no change in resting metabolism. Cardiovascular health indexes were unaffected by either of the treatments, but breakfast maintained more stable afternoon and evening glycemia than did fasting. This trial was registered at www.isrctn. org as ISRCTN31521726.
Efficiency and Optimal Loads Analysis for Multiple-Receiver Wireless Power Transfer Systems

Wireless power transfer has shown revolutionary potential in challenging the conventional charging method for consumer electronic devices. Through magnetic resonance coupling, it is possible to supply power from one transmitter to multiple receivers simultaneously. In a multiple-receiver system, the overall system efficiency highly depends on the loads' and receivers' positions. This paper extends the conventional circuit-model-based analysis for the one-receiver system to investigate a general one-transmitter multiple-receiver system. It discusses the influence of the loads and mutual inductance on the system efficiency. The optimal loads, the input impedance, and power distribution are analyzed and used to discuss the proper system design and control methods. Finally, systems with a different number of receivers are designed, fabricated, and measured to validate the proposed method. Under the optimal loading conditions, an efficiency above 80% can be achieved for a system with three different receivers working at 13.56 MHz.
Impact of Seminal Chemical Elements on the Oxidative Balance in Bovine Seminal Plasma and Spermatozoa

Mutual relationships between selected chemical elements (Na, K, Fe, Cu, Mg, and Zn), basic motility characteristics (motility and progressive motility), and markers of the oxidative balance (superoxide dismutase, catalase, glutathione, albumin, and malondialdehyde) were investigated in bovine seminal plasma and spermatozoa. Computer assisted sperm analysis was used to assess the motility parameters; mineral concentrations were determined by the voltammetric method and flame absorption spectrophotometry; antioxidants and malondialdehyde were evaluated by UV/VIS spectrophotometry. Concentrations of chemical elements in both seminal fractions were in the following descending order: Na > K > Zn > Mg > Fe > Cu. Higher amounts of all minerals and nonenzymatic antioxidants were detected in the seminal plasma (P < 0.01; P < 0.001), while higher MDA concentration and activity of enzymatic antioxidants were recorded in the cell lysates (P < 0.01; P < 0.001). Na, Fe, Cu, Mg, and Zn were positively correlated with the motility and antioxidant parameters (P < 0.05; P < 0.01; P < 0.001). Inversely, K exhibited the positive associations with malondialdehyde (P < 0.05). This study demonstrates that most chemical elements are integral components of bovine semen and are needed for the protection against oxidative stress development.
The Development of Positive Psychology on the Research of Positive Personality

Positive psychology, as it had done, suggests that personality psychology should study people's factors of strengths of personality as well as vulnerabilities. Moreover, positive psychology should study the impacts of capabilities and potentials, that is to say, study the positive traits of personality. This article analyses three pieces of positive traits of personality and concludes that it is the most efficient way to promote individual positive experiences in cultivating people's positive personalities.
A Focus on Neglect: Comparing the Characteristics of Children and Parents in Cases of Neglect, Abuse, and Non-CAN (Child Abuse and Neglect) in Israeli Rulings on Termination of Parental Rights

ABSTRACT This study attempts to expand the knowledge base about neglect by comparing the characteristics of children and parents involved in termination of parental rights proceedings in the Israeli legal system. Cases were classified as neglect (72.7%), abuse (19%) or non-child abuse or neglect (non-CAN; 8%) and were compared on a range of variables. The results show that neglected children have the most developmental problems, and generally come from single-parent families, compared to abused children, who suffer the most mental health problems and come from 2-parent families. Finally, neglect is associated with the mother’s history of drug abuse, and abuse is associated with the father’s drug abuse and criminal record. In non-CAN cases, the courts criticize the Child Protective Service more than in neglect and abuse cases. Implications of the findings for social work practice as well as future research directions are discussed.
Effects of physical activity on cognitive functioning in middle age: evidence from the Whitehall II prospective cohort study.

OBJECTIVES We examined the association between physical activity and cognitive functioning in middle age. METHODS Data were derived from a prospective occupational cohort study of 10308 civil servants aged 35-55 years at baseline (phase 1; 1985-1988). Physical activity level, categorized as low, medium, or high, was assessed at phases 1, 3 (1991-1994), and 5 (1997-1999). Cognitive functioning was tested at phase 5, when respondents were 46-68 years old. RESULTS In both prospective (odds ratio [OR] = 1.65; 95% confidence interval [CI]=1.30, 2.10) and cross-sectional (OR=1.79; 95% CI=1.38, 2.32) analyses, low levels of physical activity were a risk factor for poor performance on a measure of fluid intelligence. Analyses aimed at assessing cumulative effects (summary of physical activity levels at the 3 time points) showed a graded linear relationship with fluid intelligence, with persistently low levels of physical activity being particularly harmful (OR=2.21; 95% CI=1.37, 3.57). CONCLUSIONS Low levels of physical activity are a risk factor for cognitive functioning in middle age, fluid intelligence in particular.
Mesenchymal Stem Cell Targeting of Microscopic Tumors and Tumor Stroma Development Monitored by Noninvasive In vivo Positron Emission Tomography Imaging

The aim of this study was to assess the efficacy human mesenchymal stem cells (hMSC) for targeting microscopic tumors and suicide gene or cytokine gene therapy. Immunodeficient mice were transplanted s.c. with human colon cancer cells of HT-29 Inv2 or CCS line, and 3 to 4 days later, i.v. with “tracer” hMSCs expressing herpes simplex virus type 1 thymidine kinase (HSV1-TK) and enhanced green fluorescent protein (EGFP) reporter genes. Subsequently, these tumors were examined for specificity and magnitude of HSV1-TK+, EGFP+ stem cell engraftment and proliferation in tumor stroma by in vivo positron emission tomography (PET) with 18F-labeled 9-(4-fluoro-3-hydroxymethylbutyl)-guanine ([18F]-FHBG). In vivo PET images of tumors growing for 4 weeks showed the presence of HSV1-TK+ tumor stroma with an average of 0.36 ± 0.24% ID/g [18F]-FHBG accumulation. In vivo imaging results were validated by in situ correlative histochemical, immunofluorescent, and cytometric analyses, which revealed EGFP expression in vWF+ and CD31+ endothelial cells of capillaries and larger blood vessels, in germinal layer of dermis and hair follicles proximal to the s.c. tumor site. These differentiated HSV1-TK+, GFP+ endothelial cells had limited proliferative capacity and a short life span of <2 weeks in tumor fragments transplanted into secondary hosts. We conclude that hMSCs can target microscopic tumors, subsequently proliferate and differentiate, and contribute to formation of a significant portion of tumor stroma. PET imaging should facilitate clinical translation of stem cell–based anticancer gene therapeutic approaches by providing the means for in vivo noninvasive whole-body monitoring of trafficking, tumor targeting, and proliferation of HSV1-tk-expressing “tracer” hMSCs in tumor stroma.
Social Interactions and Monetary Incentives in Driving Consumer Repeat Behavior

Companies are eager to leverage social interactions among consumers by embedding social networking tools on their websites and actively integrating marketing actions with consumers' social activities. In this article, the authors investigate the impact of online social interactions on repeat usage behavior and the effectiveness of monetary incentives by formulating a model that parses out the effects of these individual factors. Using a unique data set from a wellness program, they find that online social interactions play a key role in driving repeat behavior, and after controlling for contemporaneous correlations from same-office friends, the social influence emanates even from distant friends working in different offices. The authors also find that monetary incentives have a significant impact on repeat usage and that ignoring this may overstate the impact of social influence. Furthermore, what-if scenario analyses show that social interactions are more effective than monetary incentives when both are present. The authors then explore social influence theories to understand the underlying process mechanisms that may operate in the repeat usage context. Using these findings, they offer strategic implications for marketing practice.
Hsp110-Mediated Enhancement of CD4+ T Cell Responses to the Envelope Glycoprotein of Members of the Family Flaviviridae In Vitro Does Not Occur In Vivo

ABSTRACT The use of heat shock proteins (HSP) to enhance activation of the immune response to chaperoned antigen is being explored for immunotherapy. Hsp110 chaperones large protein substrates more effectively than Hsp70, offering the potential to use complex antigens containing multiple epitopes in HSP-based vaccines. In this study, we investigated the ability of recombinant bovine Hsp110 to chaperone E2 glycoprotein, the major envelope protein of bovine viral diarrhea virus (BVDV) and the dominant target of neutralizing antibodies. Hsp110 formed complexes with E2, as demonstrated by immunoprecipitation. When monocytes from BVDV-immunized cattle were stimulated with these complexes and incubated with autologous CD4+ T cells, enhanced levels of proliferation were observed. To determine the ability of these complexes to improve immunogenicity in vivo, cattle were vaccinated with either Hsp110-E2 complex or E2 only, combined with Quil-A adjuvant. In contrast to the in vitro data, cellular and humoral responses to E2 were greater in the E2-only vaccination group, indicating that complex formation had actually reduced the immunogenicity of E2. This study highlights the need for further understanding of the means by which HSP complexes are endocytosed and processed in vivo to enable the design of successful vaccine strategies.
Preventing and responding to gambling-related harm and crime in the workplace

Aims Problem gambling, even if it occurs in leisure time, can cause harm in the workplace. Problem gamblers are preoccupied with gambling and often suffer from psychiatric and psychosomatic symptoms caused by their excessive gambling. This may lead to inefficiency at work and absenteeism. Severe gambling problems typically lead to a constant need for money, which may result in theft of money or goods from the workplace and in embezzlement. This paper outlines measures to prevent and respond to gambling-related harm and crime in the workplace. Methods A review of the literature and qualitative interviews with therapists specializing in problem gambling treatment, peer counsellors from mutual support societies, recovered problem gamblers who have embezzled, and professionals working in workplace crime security and the prevention of alcohol, drug and gambling harm. Results Important measures in preventing and responding to gambling harm in the workplace include: substance use and gambling policy, problem gambling awareness, attention to signs of gambling-related harm, control functions, appropriate responses to harmful gambling, and rehabilitation. Conclusion The workplace should play a greater role in the universal, selective and indicated prevention of problem gambling.
Preparation of Bioactive Titanium Surfaces via Fluoride and Fibronectin Retention

Statement of Problem. The chemical or topographic modification of the dental implant surface can affect bone healing, promote accelerated osteogenesis, and increase bone-implant contact and bonding strength. Objective. In this work, the effects of dental implant surface treatment and fibronectin adsorption on the adhesion of osteoblasts were analyzed. Materials and Methods. Two titanium dental implants (Porous-acid etching and PorousNano-acid etching followed by fluoride ion modification) were characterized by high-resolution scanning electron microscopy, atomic force microscopy, and X-ray diffraction before and after the incorporation of human plasma fibronectin (FN). The objective was to investigate the biofunctionalization of these surfaces and examine their effects on the interaction with osteoblastic cells. Results. The evaluation techniques used showed that the Porous and PorousNano implants have similar microstructural characteristics. Spectrophotometry demonstrated similar levels of fibronectin adsorption on both surfaces (80%). The association indexes of osteoblastic cells in FN-treated samples were significantly higher than those in samples without FN. The radioactivity values associated with the same samples, expressed as counts per minute (cpm), suggested that FN incorporation is an important determinant of the in vitro cytocompatibility of the surfaces. Conclusion. The preparation of bioactive titanium surfaces via fluoride and FN retention proved to be a useful treatment to optimize and to accelerate the osseointegration process for dental implants.
Dialogue, Argumentation and Education: History, Theory and Practice

New pedagogical visions and technological developments have brought argumentation to the fore of educational practice. Whereas students previously ‘learned to ‘argue’, they now ‘argue to learn’: collaborative argumentation-based learning has become a popular and valuable pedagogical technique, across a variety of tasks and disciplines. Researchers have explored the conditions under which arguing to learn is successful, have described some of its learning potentials (such as for conceptual change and reflexive learning) and have developed Internet-based tools to support such learning. However, the further advancement of this field presently faces several problems, which the present book addresses. Three dimensions of analysis historical, theoretical and empirical are integrated throughout the book. Given the nature of its object of study dialogue, interaction, argumentation, learning and teaching the book is resolutely multidisciplinary, drawing on research on learning in educational and psychological sciences, as well as on philosophical and linguistic theories of dialogue and argumentation.
Granulocyte-macrophage colony-stimulating factor to reverse sepsis-associated immunosuppression: a double-blind, randomized, placebo-controlled multicenter trial.

RATIONALE Sustained sepsis-associated immunosuppression is associated with uncontrolled infection, multiple organ dysfunction, and death. OBJECTIVES In the first controlled biomarker-guided immunostimulatory trial in sepsis, we tested whether granulocyte-macrophage colony-stimulating factor (GM-CSF) reverses monocyte deactivation, a hallmark of sepsis-associated immunosuppression (primary endpoint), and improves the immunological and clinical course of patients with sepsis. METHODS In a prospective, randomized, double-blind, placebo-controlled, multicenter trial, 38 patients (19/group) with severe sepsis or septic shock and sepsis-associated immunosuppression (monocytic HLA-DR [mHLA-DR] <8,000 monoclonal antibodies (mAb) per cell for 2 d) were treated with GM-CSF (4 microg/kg/d) or placebo for 8 days. The patients' clinical and immunological course was followed up for 28 days. MEASUREMENTS AND MAIN RESULTS Both groups showed comparable baseline mHLA-DR levels (5,609 +/- 3,628 vs. 5,659 +/- 3,332 mAb per cell), which significantly increased within 24 hours in the GM-CSF group. After GM-CSF treatment, mHLA-DR was normalized in 19/19 treated patients, whereas this occurred in 3/19 control subjects only (P < 0.001). GM-CSF also restored ex-vivo Toll-like receptor 2/4-induced proinflammatory monocytic cytokine production. In patients receiving GM-CSF, a shorter time of mechanical ventilation (148 +/- 103 vs. 207 +/- 58 h, P = 0.04), an improved Acute Physiology and Chronic Health Evaluation-II score (P = 0.02), and a shorter length of both intrahospital and intensive care unit stay was observed (59 +/- 33 vs. 69 +/- 46 and 41 +/- 26 vs. 52 +/- 39 d, respectively, both not significant). Side effects related to the intervention were not noted. CONCLUSIONS Biomarker-guided GM-CSF therapy in sepsis is safe and effective for restoring monocytic immunocompetence. Use of GM-CSF may shorten the time of mechanical ventilation and hospital/intensive care unit stay. A multicenter trial powered for the improvement of clinical parameters and mortality as primary endpoints seems indicated. Clinical trial registered with www.clinicaltrials. gov (NCT00252915).
BOLD activation of the ventromedial prefrontal cortex in patients with late life depression and comparison participants

ABSTRACT The ventromedial prefrontal cortex's (vMPFC) role in regulating emotions in late life depression (LLD) remains unclarified. We assessed vMPFC activation in an emotional valence blood oxygenation level-dependent (BOLD) functional magnetic neuroimaging (fMRI) task and related the findings to extent of white matter hyperintensities (WMH). Sixteen participants with mild to moderate LLD were compared to 14 similar aged comparison participants. Participants in the scanner viewed words matched for length and arousal, indicated the perceived valence by pressing one of the three buttons i.e. “positive, negative, or neutral. ” WMH volume was greater in LLD participants than comparison participants. There were no differences in activations between groups to any valence contrast. Female LLD participants showed greater activation for negative versus positive and negative versus neutral words as compared to female comparison participants. Female LLD participants respond differently to emotionally laden words compared to comparison participants. WMH could play a role in etiopathology of emotional perception in female LLD participants.
