Gratitude, or the Positive Side of the Relationship with Patients. Development and First Validation of New Instruments: A Scale of Gratitude Perceived by Operators and a Scale of Support Offered by the Gratitude Expressed by Their Patients  [PDF]
Mara Martini, Daniela Converso
Psychology (PSYCH) , 2014, DOI: 10.4236/psych.2014.56067

The relationship with patients/users is a crucial dimension for helping professionals. It is nevertheless mostly analyzed in its negative connotation, that’s to say as a possible cause, for example, of the burnout syndrome, while very few are research works that take into account the positive side of the relationship, as a resource more than a problem, and even fewer are the instruments to measure it. The aim of the present work is the development and the analysis of the characteristics of a scale to measure the gratitude expressed by patients perceived by operators and of a scale to measure the perception of support that gratitude by patients/customers offers to relieve the fatigue of daily commitment and return significance to their work. The two scales were developed and then integrated into a questionnaire including items regarding the negative side of the relationship (exceeding requests from patients) and the Customer-initiated support scale (Zimmermann et al., 2011). The questionnaire was filled in by 267 nurses in Piedmont, Italy. Descriptive analyses on each item, exploratory factor analysis, Cronbach’s alpha, analysis of variance, and bivariate correlations were conducted. Both scales show a one-factor solution. The independent sample t-tests highlighted differences between men and women and between people who have families to care for and people who do not. Bivariate correlations signalled a positive relationship between both the gratitude scales and the Customer-initiated support; no relationships are evident with the scale of exceeding request from patients. A limitation of the work is the dimension of the sample: a more extensive administration of the questionnaire is currently in progress that will also permit to more deeply investigate the factorial structure of the scales. The scales will allow filling a gap in measuring a central work issue for helping professions.

Abstract: Shigella flexneri is endemic in most underdeveloped countries, causing diarrheal disease and dysentery among young children. In order to reach its target site, the colon, Shigella must overcome the acid environment of the stomach. Shigella is able to persist in this stressful environment and, because of this ability it can initiate infection following the ingestion of very small inocula. Thus, acid resistance is considered an important virulence trait of this bacterium. It has been reported that moderate acid conditions regulate the expression of numerous components of the bacterial envelope. Because the lipopolysaccharide (LPS) is the major component of the bacterial surface, here we have addressed the role of LPS in acid resistance of S. flexneri 2a. Defined deletion mutants in genes encoding proteins involved in the synthesis, assembly and length regulation of the LPS O antigen were constructed and assayed for resistance to pH 2.5 after adaptation to pH 5.5. The results showed that a mutant lacking O antigen was significantly more sensitive to extreme acid conditions than the wild type. Not only the presence of polymerized O antigen, but also a particular polymer length (S-OAg) was required for acid resistance. Glucosylation of the O antigen also contributed to this property. In addition, a moderate acidic pH induced changes in the composition of the lipid A domain of LPS. The main modification was the addition of phosphoethanolamine to the 1′ phosphate of lipid A. This modification increased resistance of S. flexneri to extreme acid conditions, provide that O antigen was produced. Overall, the results of this work point out to an important role of LPS in resistance of Shigella flexneri to acid stress.

Open Journal of Social Sciences (JSS) , 2015, DOI: 10.4236/jss.2015.34002
Abstract: The presence of migrants as a phenomenon of globalization forces the various world health systems to face up to the problem of inequality penalising this population. Although new to immigration, Italy has seen an increase in immigrant health inequalities. Access to health services is a critical issue here.
Recourse to Complementary/Alternative Medicine (CAM) at Times of Economic Crisis: The Case of Italy  [PDF]
Mara Tognetti
Open Journal of Social Sciences (JSS) , 2017, DOI: 10.4236/jss.2017.57023
Abstract: The economic crisis that has invested western countries in the last years has determined a significant reduction in consumption of medication and treatments recourse, too. The Economic recession is generally accompanied by a decrease in health-related consumption, varying according to the welfare model, and especially affecting people of working age with a low income. The present paper focuses on the effects of the economic crisis on users of Complementary/Alternative Medicine treatments (from now on referred as CAM). Based on multi-purpose data analyses, this work aims to examine what kind of strategies such consumers have adopted in order not to neglect their health despite feeling the economic pinch. Our analyses are principally based on ISTAT, Italian National Institute for Recording Statistics findings. Specifically, our research is based on the survey “Health conditions and recourse to health services”. The analysed data refer to the Italian context in the period comprised from 2000 to 2013. The results of this work reveal how, in this delicate phase of the economy, traditional consumers of CAM have signally reduced their use of such treatments. In Italy, in the observed period, factors as working status, age, smoking and chronic diseases have been determinant in the decision to use CAM. The article suggests that, where health is at stake, CAM users are more strategic than the average biomedicine users. Furthermore, confirming the past trend, it shows how difficult it is to afford forms of treatment not covered by the health system as well as it underlines the lack of data for comparison with other countries.
IL-1 inhibition in autoinflammatory diseases

Abstract: Muckle-Wells Syndrome, Familial Cold Autoinflammatory Syndrome and Chronic Infantile Neurological Cutaneous and Articular Syndrome are IAS due to mutations in a single gene, CIAS1 (cold-induced autoinflammatory syndrome 1, or NALP-3), encoding a protein called cryopyrin which is an essential component of an intracellular multiprotein complex named inflammasome, that play a crucial role in the production and secretion of interleukin (IL)-1 These diseases are characterized by excessive production of IL-1 and have a dramatic response to IL-1 inhibition.More recently, IL-1 inhibition has also been shown to be effective in another AID (TNF-receptor associated periodic syndrome or TRAPS) as well as in other conditions such as systemic juvenile idiopathic arthritis and recurrent idiopathic pericarditis. This has suggested that also these two last diseases may represent autoinflammatory conditions.

Abstract: Coagulation complications are significant contributors to morbidity and mortality in trauma patients [1,2]. Mortality in patients with severe injuries and coagulopathy is found to be four times greater than in patients with injuries alone [3]. Trauma-related coagulopathy is associated with hypoperfusion due to tissue injury and blood loss, hemodilution from resuscitation with crystalloid and/or colloid solutions, progressive hypothermia and the development of acidosis. Since the recognition of the lethal triad of hypothermia, acidosis, and coagulopathy over a decade ago [1,2], a great deal of effort has been made to elucidate possible mechanisms contributing to trauma related coagulopathy as well as to search for effective treatments [4-7]. Recent data suggest that fibrinogen availability may play an important role in the survival of patients. The purpose of this article is to review recent findings that have been made concerning clotting protein fibrinogen metabolism and availability following trauma-related events, including hemorrhage, resuscitation, hypothermia and acidosis.As the precursor of clot formation, fibrinogen plays an important role in coagulation function. Fibrinogen deficiency is associated with uncontrolled bleeding and compromised survival [8-12]. Thus, regulation of fibrinogen availability is critical to survival in trauma patients.As an acute phase protein, fibrinogen is synthesized in the liver and released into the circulation. It is catabolized through normal protein degradation, the coagulation process, and other unknown pathways. At any moment, fibrinogen availability is delineated by the dynamic balance of synthesis and breakdown. Mathematically, fibrinogen availability can be expressed as:Where [fibrinogen] is the initial fibrinogen concentration (mg/dL); synthesis is the amount of fibrinogen (mg) produced in a unit of time (hour); and breakdown rate is the amount of fibrinogen (mg) consumed in a unit of time (hour).The importance of init
