Review of the book Michail Bachtin. Una critica al pensiero dialogico.All’interno dell’ampio campo degli studi bachtiniani il volume Michail Bachtin. Una critica al pensiero dialogico si offre come un’introduzione all’opera del pensatore russo. Spaziando dall’antropologia filosofica alla riflessione sul linguaggio, dall’estetica alla teoria del romanzo, Stefania Sini ripercorre i campi del sapere che hanno interessato il pensiero di Michail Bachtin, sottolineandone la portata interdisciplinare legata non solo alla pluralità dei suoi interessi, ma anche al metodo di indagine ad essi connaturato

Ruxolitinib – better prognostic impact in low-intermediate 1 risk score: evaluation of the ‘rete ematologica pugliese’ (REP) in primary and secondary myelofibrosis

We evaluated ruxolitinib in 65 patients with myelofibrosis according to age, sex, time of diagnosis, grade of fibrosis, prognostic score risk, Janus kinase (JAK) status, primary or secondary myelofibrosis, previous treatment, and dosage. Outcome measures were response rate, time to response, duration of response, and event-free survival and survival. Kaplan and Meier curves show a significant difference in event-free survival according to the prognostic score, in favor of patients with low int1 (p = 0.0009). The Cox stepwise model confirmed the result, the int2 high-risk score being the most powerful negative independent parameter (0.001), followed by JAK (0.008); other parameters, such as diagnosis more than 5 years earlier, grade III–IV fibrosis, and ruxolitinib dose have a negligible impact. Time to response was shorter (p = 0.001) in primary myelofibrosis. In conclusion, ruxolitinib is effective, with a better outcome in patients with a low-int1 risk score. This may suggest considering an earlier administration in the disease course

Dietary Patterns and Blood Biochemical and Metabolic Parameters in an Italian Population: A Cross-Sectional Study

Diet has long been identified as a major determinant of cardiovascular and other chronic diseases. In this study, we assess the relation between adherence to different dietary patterns and biochemical and metabolic parameters as well as the 10-year risk of major cardiovascular diseases (CVDs) in a community of blood donors in Northern Italy. We assess their adherence to four dietary patterns, namely, the Dietary Approach to Stop Hypertension (DASH) diet, the Mediterranean diet through the Greek and Italian Mediterranean Indices (GMI and IMI) and the Mediterranean-DASH Intervention for Neurodegenerative Delay (MIND) diet, using a validated semi-quantitative food frequency questionnaire (FFQ). We then assess their association with blood parameters and the 10-year risk of major CVD using a spline regression model. We found an inverse association between the DASH and MIND diets and total and LDL cholesterol, and triglyceride and HDL cholesterol values for the Mediterranean diets (IMI and GMI). Additionally, according to our sex-stratified analyses, men who have greater adherence to dietary patterns have a decreased risk of major CVD for all patterns. The results suggest that greater adherence to dietary patterns positively influences blood biochemical and metabolic parameters, thus reducing the risk of developing cardiovascular disease and delaying the use of drug treatment

The clinical effectiveness of an integrated multidisciplinary evidence-based program to prevent intraoperative pressure injuries in high-risk children undergoing long-duration surgical procedures: a quality improvement study

The prevention of hospital-acquired pressure injuries (HAPIs) in children undergoing long-duration surgical procedures is of critical importance due to the potential for catastrophic sequelae of these generally preventable injuries for the child and their family. Long-duration surgical procedures in children have the potential to result in high rates of HAPI due to physiological factors and the difficulty or impossibility of repositioning these patients intraoperatively. We developed and implemented a multi-modal, multi-disciplinary translational HAPI prevention quality improvement program at a large European Paediatric University Teaching Hospital. The intervention comprised the establishment of wound prevention teams, modified HAPI risk assessment tools, specific education, and the use of prophylactic dressings and fluidized positioners during long-duration surgical procedures. As part of the evaluation of the effectiveness of the program in reducing intraoperative HAPI, we conducted a prospective cohort study of 200 children undergoing long-duration surgical procedures and compared their outcomes with a matched historical cohort of 200 children who had undergone similar surgery the previous year. The findings demonstrated a reduction in HAPI in the intervention cohort of 80% (p < 0.01) compared to the comparator group when controlling for age, pathology, comorbidity, and surgical duration. We believe that the findings demonstrate that it is possible to significantly decrease HAPI incidence in these highly vulnerable children by using an evidence-based, multi-modal, multidisciplinary HAPI prevention strategy

Voices from the Borders. Feridun Zaimoglu’s <i>Kanaksprak</i>

Kanak Sprak, a collection of reportages by the Turkish-German author Feridun Zaimoglu issued in 1995, suggests two considerations: on the one hand on the strategies of empowerment of the stigma “Kanake”, which labels Turkish and other Germans with migration background who have been raised in the Federal Republic; on the other hand on the distortion of the mainstream language as a strategy of decolonization. Hence, this paper focuses on the subversion of the stereotype and the “relexification” of the language. The stereotype works – as Homi Bhabha claims – like an apparatus, a deployment in which relations of force are formed and operate. By turning the stereotype into an articulation of their difference, Zaimoglu’s Kanaken try to subvert the hegemonic gaze, which contains their fluid identity into a label, and thus to assert their “in-betweeness” as “synthetic products”. Yet, their strategy of empowerment works as a performance of codes of behaviour and of a body language, which turn to absorb the mainstream gaze, failing in the claim for a resistant identity. Furthermore their corrupted language, which is neither German nor Turkish, but a sort of provocative street slang rich in vernacular terms, works as a “relexification”, as Chantal Zabus calls the attempt to corrupt an European language with elements from another cultural substrate. Yet, Zaimoglu’s rendering of it sounds like a mockery of this slang, as the hegemonic German culture usually encodes it. So, the fluid border crossing of Kanak interstitial identity in the end crystallizes in a mimicry, in which both codes of behaviour and language structures become a metonymic representation of difference

Relationship of fruit and vegetable intake to dietary antioxidant capacity and markers of oxidative stress: A sex-related study

Oxidative stress contributes to the development of chronic diseases. Fruits and vegetables contain several phytonutrients (carotenoids, polyphenols) that exert antioxidant effects. The aim of this study was to investigate sex differences in fruit and vegetable intake, and the relationship to plasma levels of carotenoids as well as to total antioxidant capacity (pTAC). We studied also sex differences in the relationship between fruit and vegetables intake and plasma levels of lipid hydroperoxides, as well as of oxidized low-density lipoprotein (ox-LDL)

Association between cadmium and genotoxicity and oxidative stress risk biomarkers in a population of Northern Italy

Cadmium is a toxic heavy metal exerting several adverse effects in humans, especially for kidney, bone, liver, and cardiovascular system. In particular, genotoxic effects may occur through several epigenetic mechanisms, but a direct genotoxicity has been suggested. 8-oxo-7,8-dihydro-2’deoxyguanosine (8-oxodG) is an oxidized derivative of deoxyguanosine, largely used as biomarker of oxidative stress in urine. In this study, we aimed to assess cadmium levels in a population in Northern Italy, in order to evaluate the correlation between cadmium exposure with different haematological and biochemical parameters, as well as the relationship with 8-oxodG levels. METHODS: We recruited healthy and non-smoking subjects living in the Reggio Emilia province in the period 2017-2019 at the Transfusion Medicine Unit of Santa Maria Nuova Hospital, AUSL-IRCCS of Reggio Emilia, Northern Italy. Urinary cadmium and 8-oxodG, and fasting blood haematological and biochemical parameters were assessed. RESULTS:We eventually recruited 140 participants (mean age 47.4 years). Mean urinary cadmium and 8-oxodG levels were 0.25 µg/L (range: 0.01–1.33 µg/L) and 3.68 µg/g creatinine respectively. All haematological and biochemical parameters were in the normal range. We found a positive association of cadmium concentrations with alanine aminotransferase, total cholesterol, triglyceride, and TSH levels, while a negative one was observed with glycaemia, HDL levels. In addition, we found a strong positive correlation between urinary cadmium and 8-oxodG. CONCLUSIONS:Our study suggests that cadmium exposure is associated with detrimental effects on some haematological and biochemical parameters even at very low levels, generally considered safe for the general population. The positive association between urinary cadmium levels and oxidative stress, as assessed through 8-oxodG levels, highlights the potential role of this heavy metal in causing direct genotoxic effects.
