Gender differences in pain prevalence, characteristics, assessment and treatment in internal medicine patients: a post-hoc analysis of the FADOI-DOMINO study

Conflicting results come from epidemiological studies on the correlations between gender and pain in hospitalized patients. No specific data are reported in patients admitted to Internal Medicine Units (IMUs). Post-hoc analysis of the FADOI-DOMINO study, performed in 26 IMUs in Italy, with two cross-sectional surveys interspersed with an educational program. The 5200 medical charts of the FADOI-DOMINO study were re-analyzed. The following sex differences were highlighted: i) a greater pain prevalence was evidenced in women in the Pre-phase; ii) among patients with chronic pain, anxiety and depression were significantly more present in women compared with men; iii) oncologic pain was more prevalent in men; in a specular way, nononcologic pain showed a greater prevalence in women in both phases; iv) strong opioids therapy was higher for men. Some sex differences in pain seem to exist in IMUs, although less evident if compared with those previously reported in other settings. A more careful assessment of coexisting conditions such as anxiety, depression or cognitive impairment can result in a better management of these problems

The Skeletal Organic Matrix from Mediterranean Coral Balanophyllia europaea Influences Calcium Carbonate Precipitation

Scleractinian coral skeletons are made mainly of calcium carbonate in the form of aragonite. The mineral deposition occurs in a biological confined environment, but it is still a theme of discussion to what extent the calcification occurs under biological or environmental control. Hence, the shape, size and organization of skeletal crystals from the cellular level through the colony architecture, were attributed to factors as diverse as mineral supersaturation levels and organic mediation of crystal growth. The skeleton contains an intra-skeletal organic matrix (OM) of which only the water soluble component was chemically and physically characterized. In this work that OM from the skeleton of the Balanophyllia europaea, a solitary scleractinian coral endemic to the Mediterranean Sea, is studied in vitro with the aim of understanding its role in the mineralization of calcium carbonate. Mineralization of calcium carbonate was conducted by overgrowth experiments on coral skeleton and in calcium chloride solutions containing different ratios of water soluble and/or insoluble OM and of magnesium ions. The precipitates were characterized by diffractometric, spectroscopic and microscopic techniques. The results showed that both soluble and insoluble OM components influence calcium carbonate precipitation and that the effect is enhanced by their co-presence. The role of magnesium ions is also affected by the presence of the OM components. Thus, in vitro, OM influences calcium carbonate crystal morphology, aggregation and polymorphism as a function of its composition and of the content of magnesium ions in the precipitation media. This research, although does not resolve the controversy between environmental or biological control on the deposition of calcium carbonate in corals, sheds a light on the role of OM, which appears mediated by the presence of magnesium ions

Differential diagnosis of neurodegenerative dementias with the explainable MRI based machine learning algorithm MUQUBIA

Biomarker-based differential diagnosis of the most common forms of dementia is becoming increasingly important. Machine learning (ML) may be able to address this challenge. The aim of this study was to develop and interpret a ML algorithm capable of differentiating Alzheimer's dementia, frontotemporal dementia, dementia with Lewy bodies and cognitively normal control subjects based on sociodemographic, clinical, and magnetic resonance imaging (MRI) variables. 506 subjects from 5 databases were included. MRI images were processed with FreeSurfer, LPA, and TRACULA to obtain brain volumes and thicknesses, white matter lesions and diffusion metrics. MRI metrics were used in conjunction with clinical and demographic data to perform differential diagnosis based on a Support Vector Machine model called MUQUBIA (Multimodal Quantification of Brain whIte matter biomArkers). Age, gender, Clinical Dementia Rating (CDR) Dementia Staging Instrument, and 19 imaging features formed the best set of discriminative features. The predictive model performed with an overall Area Under the Curve of 98%, high overall precision (88%), recall (88%), and F1 scores (88%) in the test group, and good Label Ranking Average Precision score (0.95) in a subset of neuropathologically assessed patients. The results of MUQUBIA were explained by the SHapley Additive exPlanations (SHAP) method. The MUQUBIA algorithm successfully classified various dementias with good performance using cost-effective clinical and MRI information, and with independent validation, has the potential to assist physicians in their clinical diagnosis

Patient and physician views on the quality of care in inflammatory bowel disease: Results from SOLUTION-1, a prospective IG-IBD study.

Introduction: Remarkable differences in quality of care (QoC) might be observed in different countries, affecting quality of life of inflammatory bowel disease (IBD) patients. The aim of this study was to assess patient and physician perceptions of the QoC in Italy. Methods: A multicentre observational study on the quality of care in IBD (SOLUTION-1) was conducted in 36 IG-IBD (Italian Group for Inflammatory Bowel Disease) centres in Italy. The QUOTE-IBD (Quality of Care Through the Patient's Eyes) questionnaire was administered to IBD patients and to the attending physicians. The Quality Impact (QI) score summarises the QUOTE-IBD questionnaire, and a QI > 9 is considered satisfactory. Results: Nine-hundred-ninety-two patients and 75 physicians completed the QUOTE-IBD questionnaire. The patients scored the domains of competence (9.47 vs. 8.55) and costs (9.54 vs. 8.26) higher that the physicians, while information (9.31 vs. 9.43) and continuity of care (8.40 vs. 9.01) were scored lower. The QI score was rated worse by physicians with less experience (<. 12. years) with regard to competence (8.0 vs. 9.01), courtesy (8.12 vs. 10.0) and autonomy (8.97 vs. 10.0). Physicians considered the cost domain unsatisfactory. Conclusions: Healthcare was rated as satisfactory overall for Italian patients and physicians. The physicians underestimate their competence and consider the cost of medical management unsatisfactory. The patients are more critical regarding the continuity of care and information. Country-specific data on QoC allow local governments to allocate resources more effectively. © 2014 European Crohn's and Colitis Organisation

The prevalence of genetic and serologic markers in an unselected European population-based cohort of IBD patients

BACKGROUND AND AIM: The aetiology of inflammatory bowel disease (IBD) is unknown, but it has become evident that genetic factors are involved in disease susceptibility. Studies have suggested a north-south gradient in the incidence of IBD, raising the question whether this difference is caused by genetic heterogeneity. We aimed to investigate the prevalence of polymorphisms in CARD15 and TLR4 and occurrence of anti-Saccharomyces cerevisiae (ASCA) and antineutrophil cytoplasmic antibodies (pANCA) in a European population-based IBD cohort. METHODS: Individuals from the incident cohort were genotyped for three mutations in CARD15 and the Asp299gly mutation in TLR4. Levels of ASCA and pANCA were assessed. Disease location and behaviour at time of diagnosis was obtained from patient files. RESULTS: Overall CARD15 mutation rate was 23.9% for CD and 9.6% for UC patients (P < 0.001). Mutations were less present in the Scandinavian countries (12.1%) versus the rest of Europe (32.8%) (P < 0.001). Overall population attributable risk was 11.2%. TLR4 mutation rate was 7.6% in CD, 6.7% in UC patients and 12.3% in healthy controls (HC), highest among South European CD patients and HC. ASCA was seen in 28.5% of CD patients with no north-south difference, and was associated with complicated disease. pANCA was most common in North European UC patients and not associated with disease phenotype. CONCLUSION: The prevalence of mutations in CARD15 varied across Europe, and was not correlated to the incidence of CD. There was no association between mutations in TLR4 and IBD. The prevalence of ASCA was relatively low; however related to severe CD
