Evidence of greater severity of diabetic foot ulcers during COVID-19 pandemic: A real-life single-centre cohort study.

AIMS: In the Sars-Cov-2 pandemic era, patients with diabetes mellitus (DM) manifested more severe forms of Sars-Cov-2 with greater mortality than non-diabetic patients. Several studies documented more aggressive forms of diabetic foot ulcers (DFU) during the pandemic period even though the results were not unanimously confirmed. The aim of this study was to evaluate the clinical-demographic differences between a cohort of Sicilian diabetic patients hospitalised for DFU in the pre-pandemic 3 years and a cohort of patients hospitalised in the pandemic 2 years. MATERIALS AND METHODS: One hundred and eleven patients from the pre-pandemic period 2017-2019 (Group A) and 86 patients from the pandemic period 2020-2021 (Group B) with DFU, admitted to the division of Endocrinology and Metabolism of the University Hospital of Palermo, were retrospectively evaluated. The clinical assessment of the type, staging and grading of the lesion, and the infective complication from DFU was performed. RESULTS: No differences in HbA1c values were observed between the two groups. Group B showed a significantly higher prevalence of male subjects (p = 0.010), neuro-ischaemic ulcers (p < 0.001), deep ulcers with involvement of bones (p < 0.001), white blood count levels (p < 0.001), and reactive C protein (p = 0.001) compared to group A. CONCLUSIONS: Our data show that in the COVID-19 pandemic, a greater severity of ulcers requiring a significantly greater number of revascularisations and more expensive therapy, but without an increase in the amputation rate, was observed. These data provide novel information on the impact of the pandemic on diabetic foot ulcer risk and progression.

Ultrasound Parameters Can Accurately Predict the Risk of Malignancy in Patients with "Indeterminate TIR3b" Cytology Nodules: A Prospective Study.

The increase in the incidence of thyroid nodules with cytological findings of TIR3b requires the identification of predictive factors of malignancy. We prospectively evaluated 2160 patients from January 2018 to June 2022 and enrolled 103 patients with indeterminate cytology TIR3b nodules who underwent total (73 patients) and hemi-thyroidectomy (30 patients). Among them, 61 had a histological diagnosis of malignancy (30 classic papillary thyroid carcinoma, 19 had follicular papillary thyroid carcinoma variant, 3 had Hurtle cell carcinoma and 9 had follicular thyroid carcinoma), while 42 had a benign histology. Clinical, ultrasonographic and cytological characteristics were recorded. In addition, BRAF mutation was analysed. Patients with a histological diagnosis of malignancy had a higher frequency of nodule diameter ≤11 mm (p = 0.002), hypoechogenicity (p < 0.001), irregular borders (p < 0.001), peri- and intralesional vascular flows (p = 0.004) and microcalcifications (p = 0.001) compared to patients with benign histology. In contrast, patients with benign histology had more frequent nodules with a halo sign (p = 0.012) compared to patients with histological diagnosis of malignancy. No significant differences were found in BRAF mutation between the two groups. Our study suggests that the combination of ultrasonographic and cytological data could be more accurate and reliable than cytology alone in identifying those patients with TIR3b cytology and a histology of malignancy to be referred for thyroidectomy, thus reducing the number of patients undergoing thyroidectomy for benign thyroid disease.

Decreasing role of HCV and HBV infections as aetiological factors of hepatocellular carcinoma in Italy.

BACKGROUND: The epidemiology of hepatocellular carcinoma (HCC) is characterized by a dynamical temporal trend of well-established and emerging risk factors. METHODS: We evaluated the temporal trend of aetiological factors of HCC over the last two decades in Italy. HCC cases were recruited from two previously published national studies in 1996 and in 2008 and HCC cases were also enlisted from two national surveys in 2001 and in 2014 enrolling consecutive subjects with chronic liver disease (CLD) referring to more than 80 liver units scattered all over the country for a 6-month period. RESULTS: Out of the 9997 subjects with CLD recruited in 2001 and the 2408 recruited in 2014, 3.3% and 5.7% (P < 0.001), respectively, had HCC. The temporal trend of HBsAg -/HCV + HCC cases significantly linearly decreased from 71.1% in 1996 to 57.2% in 2014 (P < 0.001). Conversely, that of virus-negative cases significantly linearly increased from 12.1% to 28.3% (P < 0.001). The proportion of HBV-related HCC cases showed a steady low rate, reflecting the reduced endemicity of the infection in Italy. The proportion of HCC with compensated cirrhosis (i.e., Child-Pugh A) linearly increased over time from 55.6% in 1996 to 76.0% in 2014 (P < 0.001) reflecting the growing effectiveness of semi-annual ultrasound surveillance for early detection of HCC. CONCLUSION: In conclusion, with decreasing viral aetiology, an overall decrease in the incidence of HCC might be expected in the future. The proportion of metabolic diseases is conversely increasing being considered as an aetiology. The growing prevalence of metabolic disorders in the general population may further increase this trend in the years to come.

Gender differences in chronic liver diseases in two cohorts of 2001 and 2014 in Italy.

BACKGROUND: Gender differences in chronic liver disease (CLD) have been partially investigated. To extend the present knowledge, we evaluated 12,263 patients with CLD enrolled in two national surveys (9997 in 2001 and 2557 in 2014). METHODS: The two surveys prospectively recruited patients aged ≥ 18 referring to Italian liver units throughout the country using a similar clinical approach and analytical methods. RESULTS: The overall male to female ratio (M/F) was 1.4 (7138/5124). Compared with females, males were significantly more likely to be younger (52.9 vs. 58.7 yrs.), with HBV infection alone (13.2% vs. 9.2%) and with alcoholic liver disease alone (11.4% vs. 6.9%), but less likely to show HCV infection alone (48.0% vs. 67.9%). A male preponderance was observed in HBV-related cases (1.99) and in alcoholic-related cases (2.3), a preponderance observed both in the 2001 and in 2014 cases. In HCV-related cases, however, females predominated in 2001 (M/F 0.9) and males in 2014 (M/F 1.5).The rate of cirrhosis in alcohol-related etiology was close to 36% in both genders, a finding much higher than that observed for both sexes in HBV and HCV etiologies.Both males and females enrolled in 2014 were older (p < 0.001) and with a higher rate of cirrhosis and/or HCC (p < 0.001) than those investigated in 2001. There was a remarkable increase over time in the proportion of male abstainers (36.7% in 2001 and 64.3% in 2014). CONCLUSION: This study highlights important inter- and intra-gender differences in the characteristics and etiological factors of patients with CLD in Italy.

Hepatitis delta infection in Italian patients: towards the end of the story?

BACKGROUND: The endemicity of hepatitis delta virus infection in Italy has decreased in the last decades. AIM: To evaluate the current epidemiology of chronic delta infection in Italy and to compare the present findings with the corresponding figures from the previous studies. METHODS: A cross-sectional study involving 16 referral centres scattered all over the country in 2014. RESULTS: Out of the 513 hepatitis B surface antigen-positive subjects enrolled, 61 (11.9%) were anti-delta positive, with a sex ratio (M/F) of 2.05. The majority (80.3%) of them was 50 years or older, while the proportion of subjects younger than 30 years of age was as low as 3.3%. No difference was detected by geographical area of residence. The presence of liver cirrhosis was diagnosed in 52.4% of cases. In comparison to previous studies, a further shift towards the oldest age groups and an increasing proportion of subjects having liver cirrhosis among all anti-delta-positive subjects are observed. CONCLUSIONS: Currently, hepatitis delta infection mostly affects old people who have an advanced but indolent liver disease, reflecting a survival effect. The defective hepatitis delta virus is near to disappear in the country, where it has been discovered in the second half of 70s.

Gender differences in chronic HBsAg carriers in Italy: Evidence for the independent role of male sex in severity of liver disease.

It has been shown that sexual hormones have an opposite effect on hepatic fibrosis progression and hepatocellular carcinoma development. Sex differences among 2,762 chronic HBsAg carriers consecutively referring Italian hospitals in 2001 and in 2007 have been evaluated, particularly focusing on the role of gender on severity of liver disease. The overall sex ratio (males/females) was 2.6. Females were more likely born abroad and new diagnosis cases; but less likely HIV coinfected. No sex difference was observed regarding coinfection with other hepatitis viruses. The sex ratio linearly increased with increasing severity of liver disease, being 1.3 in normal ALT, 2.8 in chronic hepatitis, 3.6 in liver cirrhosis, and 6.8 in hepatocellular carcinoma. Adjustment by multiple logistic regression analysis for the confounding effect of age, alcohol intake, HDV infection, HCV infection, and BMI shows that male gender is an independent predictor of the likelihood of more severe liver disease (O.R. 1.7; C.I. 95% = 1.3-2.1). HBV-DNA levels resulted not associated with the outcome of chronic HBV infection. Despite some potential risk factors associated with liver disease, such as HBV genotype or mutations, not having been controlled for due to lack of availability, the observed sex disparity in the outcome of chronic HBV infection may support biological observation that HBV infection could be considered a sex hormone-responsive virus.

Significance of serum Il-9 levels in inflammatory bowel disease.

IL-9, which may be an inflammatory or regulatory cytokine, can be experimentally produced in a Th17 or modified Th2 context in the presence of T cell receptor (TCR) stimulation. The primary aim of this study was to measure serum IL-9 levels in patients with inflammatory bowel disease (IBD), and evaluate their relationships with the patients' clinical characteristics. The secondary aim was to determine the levels of interferon-γ (IFN (interferon)-γ), Th2 cytokines (IL-4, IL-5 and IL-13), and IL-6 in order to clarify the context of detectable peripheral cytokines in which IL-9 is produced.Venous blood samples of 43 IBD patients (20 with Crohn's disease [CD] and 23 with ulcerative colitis [UC]) were analysed by means of quantitative enzyme-linked immunosorbent assays using purified anti-human IL-4, IL-5, IL-13, IFN-γ, IL-9 and IL-6 antibodies, and the laboratory findings were statistically correlated with their clinical expression.None of the patients showed the peripheral presence of IL-4, IL-5 and IL-13. Forty (93%) were positive for IFN-γ, thus confirming the presence of Th1 in both UC and CD, and IFN-γ levels correlated with disease activity (P = 0.045). Eighteen patients (41%) were positive for IL-9, which was associated with a severe prognosis (P <0.001), and 72.2% of the IL-9-positive patients were also IL-6 positive. There was a significant correlation between disease severity and IL-9 in the CD patients (P <0.001), but not in the UC patients (P = 0.1).Our findings confirm the presence of common Th1 cytokines in UC and CD. However the IL-9 positivity indicates the presence of an alternative population of T cells that respond to antigen stimulation and condition the prognosis of IBD. The fact that the same serum IL-9 levels were differentially associated with clinical measures of CD and UC activity suggest that the same cytokine can be produced in different contexts.

Increased frequency of microalbuminuria in patients with type 3 autoimmune polyglandular syndrome (APS) compared to isolated autoimmune type 1 diabetes mellitus: A real-life study.

AIM OF THE STUDY: The primary aim of the study was to evaluate the differences in metabolic control and chronic microvascular complications in patients with type 3 autoimmune polyglandular syndrome (APS3), compared to type 1 diabetes mellitus (T1DM) alone. Secondary aims were to evaluate the age of autoimmune thyroid disease (AIT) onset and the effects of levothyroxine treatment on metabolic control in patients with APS3. MATERIAL AND METHODS: We retrospectively reviewed 276 patients with T1DM alone and 214 patients with APS3 and evaluated clinical and metabolic parameters and microvascular complications. RESULTS: Patients with T1DM showed a longer duration of diabetes (p = 0.001) and lower age of diabetes onset (p = 0.020) compared to patients with APS3. Female gender (p = 0.001) and microalbuminuria (p = 0.006) were significantly more frequent in patients with APS3 compared to T1DM. In addition, patients with APS3 showed higher AIT onset frequency in the 16-30 quartile age-range. Furthermore, APS3 patients treated with levothyroxine showed significantly better HbA1c values than non-treated patients (p = 0.001). CONCLUSIONS: We found that patients with APS3 showed positive microalbuminuria, earlier than T1DM. Patients with APS3 showed higher frequency of AIT age of onset in the 16-30 age-range and those treated with levothyroxine had better metabolic control, than untreated ones.

COVID-19: The Development and Validation of a New Mortality Risk Score.

Background: The coronavirus disease 2019 (COVID-19) pandemic has found the whole world unprepared for its correct management. Italy was the first European country to experience the spread of the SARS-CoV-2 virus at the end of February 2020. As a result of hospital overcrowding, the quality of care delivered was not always optimal. A substantial number of patients admitted to non-ICU units could have been treated at home. It would have been extremely useful to have a score that, based on personal and clinical characteristics and simple blood tests, could have predicted with sufficient reliability the probability that a patient had or did not have a disease that could have led to their death. This study aims to develop a scoring system to identify which patients with COVID-19 are at high mortality risk upon hospital admission, to expedite and enhance clinical decision making. Methods: A retrospective analysis was performed to develop a multivariable prognostic prediction model. Results: Derivation and external validation cohorts were obtained from two Italian University Hospital databases, including 388 (10.31% deceased) and 1357 (7.68% deceased) patients with confirmed COVID-19, respectively. A multivariable logistic model was used to select seven variables associated with in-hospital death (age, baseline oxygen saturation, hemoglobin value, white blood cell count, percentage of neutrophils, platelet count, and creatinine value). Calibration and discrimination were satisfactory with a cumulative AUC for prediction mortality of 0.924 (95% CI: 0.893-0.944) in derivation cohorts and 0.808 (95% CI: 0.886-0.828) in external validation cohorts. The risk score obtained was compared with the ISARIC 4C Mortality Score, and with all the other most important scores considered so far, to evaluate the risk of death of patients with COVID-19. It performed better than all the above scores to evaluate the predictability of dying. Its sensitivity, specificity, and AUC were higher than the other COVID-19 scoring systems when the latter were calculated for the 388 patients in our derivation cohort. Conclusions: In conclusion, the CZ-COVID-19 Score may help all physicians by identifying those COVID-19 patients who require more attention to provide better therapeutic regimens or, on the contrary, by identifying those patients for whom hospitalization is not necessary and who could therefore be sent home without overcrowding healthcare facilities. We developed and validated a new risk score based on seven variables for upon-hospital admission of COVID-19 patients. It is very simple to calculate and performs better than all the other similar scores to evaluate the predictability of dying.

Food Beliefs and the Risk of Orthorexia in Patients with Inflammatory Bowel Disease.

Patients with inflammatory bowel disease (IBD) believe that diet plays a significant role in the pathogenesis of their disease and the exacerbation of their symptoms. They often adopt restrictive diets that can lead to malnutrition, anxiety, and stress. Recent studies have found a correlation between IBD and eating disorders, such as anorexia nervosa and ARFID (Avoidant Restrictive Food Intake Disorder). None of these studies report an association with orthorexia nervosa, which is an obsession with healthy and natural foods. The aim of this study was to assess the risk of orthorexia nervosa in patients with IBD. A total of 158 consecutive subjects were recruited, including 113 patients with IBD and 45 controls. The standardized Donini questionnaire ORTO-15 was administered to assess the risk of orthorexia, and clinical and demographic data were collected. The results showed that patients with IBD had a risk of developing orthorexia nervosa of 77%. This was significantly higher than the 47% observed in the control group. In the patients with IBD, the risk of orthorexia was associated with a lower BMI, at least in patients older than 30 years, and it was also associated with marital status in patients younger than 30. In conclusion, many patients with IBD are at increased risk of developing orthorexia nervosa, which may have a negative impact on their psychological wellbeing and social sphere, expose them to a high risk of nutritional deficiencies, and affect their overall quality of life. Further high-quality studies are needed to assess the clinical impact of orthorexia and its correlation with clinical features and classified eating disorders.

Mortality risk according to different clinical characteristics of first episode of liver decompensation in cirrhotic patients: a nationwide, prospective, 3-year follow-up study in Italy.

OBJECTIVES: The occurrence of decompensation marks a crucial turning point in the course of cirrhosis. The purpose of this study was to assess the risk of mortality according to the clinical characteristics of first decompensation, considering also the impact of acute-on-chronic liver failure (AoCLF). METHODS: We conducted a prospective nationwide inception cohort study in Italy. Decompensation was defined by the presence of ascites, either overt or detected by ultrasonography (UD), gastroesophageal variceal bleeding (GEVB), and hepatic encephalopathy (HE). AoCLF was defined according to the Asian Pacific Association for the Study of the Liver criteria. Multivariable Cox proportional hazards regression was used to analyze the risk of failure (death or orthotopic liver transplantation (OLT)). RESULTS: A total of 490 consecutive cirrhotic patients (314 males, mean age 60.9±12.6 years) fulfilled the study criteria. AoCLF was identified in 59 patients (12.0%). Among the remaining 431 patients, ascites were found in 330 patients (76.6%): in 257 (77.8%) as overt ascites and in 73 (22.2%) as UD ascites. GEVB was observed in 77 patients (17.9%) and HE in 30 patients (7.0%). After a median follow-up of 33 months, 24 patients underwent OLT and 125 died. The cumulative incidence of failure (death or OLT) after 1, 2, and 3 years was, respectively, 28, 53, and 62% in patients with AoCLF; 10, 18, and 25% in patients with UD ascites; 17, 31, and 41% in patients with overt ascites; and 8, 12, and 24% in patients with GEVB (P<0.0001). CONCLUSIONS: AoCLF is responsible for a relevant proportion of first decompensation in cirrhotic patients and is associated with the poorest outcome. Patients with UD ascites do not have a negligible mortality rate and require clinical monitoring similar to that of patients with overt ascites.

Morphological distribution of µ chains and cd15 receptors in colorectal polyp and adenocarcinoma specimens.

BACKGROUND: We have recently investigated the localisation of immunoglobulin-producing cells (IPCs) in inflamed intestinal tissue samples from patients with inflammatory bowel disease (IBD), and identified two main patterns of B lymphocyte infiltration: one characterised by the moderate strong stromal localisation of small B1 cell-like IgM+/CD79+/CD20-/CD21-/CD23-/CD5 ± IPCs, and the other by the peri-glandular localisation of IPCs with irregular nuclei that had surface markers specific for a B cell subset (IgM and CD79), but quantitative differences in their λ and κ chains. The same patients were also tested for CD15+ receptors, which were localised on inflammatory cell surfaces or in the crypts of the intestinal epithelium. CD15+ receptor distribution in inflamed tissues was limited to the cell structures. The aim of the study was to analyse variations in IPCs and CD15+ cell morphology or distribution in bowel biopsy specimens taken from patients with pre-malignant polyps or adenocarcinomas. METHODS: IPCs were analysed by means of immunofluorescence using polyclonal goat anti-human µ chains. The pre-malignant polyp specimens were tested for B cell surface phenotype λ and κ chains, CD79, CD20, CD21 and CD23 using an immunoperoxidase method. CD15+ cells were evaluated using the immunoperoxidase method and monoclonal anti-CD15 IgM. RESULTS: The study involved 14 patients (four with pre-malignant polyps and 10 with colorectal adenocarcinomas). The distribution of µ chains and CD15 markers varied in all of the biopsies, but delineated normal cell structures in the pre-malignant polyp specimens. B cell surface phenotype analysis of µ chain-positive cells identified a subset of CD79+/CD20-/CD21-/CD23- IPCs. The IPCs in certain areas showed the sporadic disintegration of inflammatory cell membranes or the accumulation of fluorescence in individual cells. IPC membrane disintegration was particularly marked in all of the adenocarcinoma samples, in which the CD15 markers also showed epithelial cell involvement. Furthermore, six of the ten adenocarcinoma samples had atypical and reorganised membranes that expressed an excess of both receptors and isolated small portions of tissue within the tumour. CONCLUSION: The findings of this preliminary morphological study suggest the presence of membrane disintegration and remodelling mechanisms in the tumours. The newly-formed membranes expressed high concentrations of inflammatory cell receptors that can confer adhesive properties.

N-Acetylcysteine for Preventing Acetaminophen-Induced Liver Injury: A Comprehensive Review.

Aims: N-Acetylcysteine (NAC) is used as an antidote in acetaminophen (APAP) overdose to prevent and mitigate drug-induced liver injury (DILI). Our objective was to systematically review evidence of the use of NAC as a therapeutic option for APAP overdose and APAP-related DILI in order to define the optimal treatment schedule and timing to start treatment. Methods: Bibliographic databases (PubMed, Web of Science, Embase, and MEDLINE) were searched for retrospective and prospective cohort studies, case series, and clinical trials. The prespecified primary outcomes were DILI-related mortality, hepatotoxicity, and adverse events (AEs). Results: In total, 34 studies of NAC usage in APAP-related DILI cases with 19,580 patients were identified, of which 2,376 patients developed hepatotoxicities. The mortality rate across different studies ranged from 0 to 52%. Large variability of NAC regimens was found, i.e., intravenous (I.V.) (100-150 mg/kg) and oral (70-140 mg/kg), and length of treatment varied-12, 24, or 48 h for I.V. regimen and 72 h for oral administration. The timing of initiation of NAC treatment showed different results in terms of occurrence of hepatotoxicity and mortality; if started within 8 h and no more than 24 h from APAP overdose, either intravenously or orally, NAC administration was efficacious in terms of mortality. The most frequent AEs reported were anaphylactic reactions, followed by cutaneous AEs for the IV route and intestinal AEs for the oral one. Conclusion: NAC improves hepatotoxicity and reduces mortality. Timing of treatment, ranging from 8 to 24 h from APAP overdose, regardless of the regimen or route of administration, is important to prevent or minimize liver damage, particularly in children and in elderly and obese patients.

B lymphocyte intestinal homing in inflammatory bowel disease.

BACKGROUND: Inflammatory bowel disease (IBD) is thought to be due to an abnormal interaction between the host immune system and commensal microflora. Within the intestinal immune system, B cells produce physiologically natural antibodies but pathologically atypical anti-neutrophil antibodies (xANCAs) are frequently observed in patients with IBD. The objective is to investigate the localisation of immunoglobulin-producing cells (IPCs) in samples of inflamed intestinal tissue taken from patients with IBD, and their possible relationship with clinical features. METHODS: The IPCs in small intestinal, colonic and rectal biopsy specimens of patients with IBD were analysed by means of immunofluorescence using polyclonal rabbit anti-human Ig and goat anti-human IgM. The B cell phenotype of the IPC-positive samples was assessed using monoclonal antibodies specific for CD79, CD20, CD23, CD21, CD5, λ and κ chains. Statistical correlations were sought between the histological findings and clinical expression. RESULTS: The study involved 96 patients (64 with ulcerative colitis and 32 with Crohn's disease). Two different patterns of B lymphocyte infiltrates were found in the intestinal tissue: one was characterised by a strong to moderate stromal localisation of small IgM+/CD79+/CD20-/CD21-/CD23-/CD5± IPCs (42.7% of cases); in the other (57.3%) no such small IPCs were detected in stromal or epithelial tissues. IPCs were significantly less frequent in the patients with Crohn's disease than in those with ulcerative colitis (p = 0.004). CONCLUSION: Our findings suggest that different immunopathogenetic pathways underlie chronic intestinal inflammation with different clinical expressions. The presence of small B lymphocytes resembling B-1 cells also seemed to be negatively associated with Crohn's disease. It can therefore be inferred that the gut contains an alternative population of B cells that have a regulatory function.

Sustained virologic response prevents the development of esophageal varices in compensated, Child-Pugh class A hepatitis C virus-induced cirrhosis. A 12-year prospective follow-up study.

UNLABELLED: The incidence of de novo development of esophageal varices (EV) in patients with compensated liver cirrhosis has been determined by few studies in the short term and never in the long term. The aims of the present study were to determine the incidence and the risk factors associated with the development of EV and to assess whether antiviral treatment and achievement of sustained virologic response (SVR) may prevent de novo EV development in patients with HCV-induced cirrhosis. We studied 218 patients with compensated EV-free, HCV-induced cirrhosis consecutively enrolled between 1989 and 1992 at three referral centers in Milan, Italy. Endoscopic surveillance was performed at 3-year intervals according to international guidelines. SVR was defined as undetectable serum HCV-RNA 24 weeks after treatment discontinuation. During a median follow-up of 11.4 years, 149/218 (68%) patients received antiviral treatment and 34 (22.8%) achieved SVR. None of the SVR patients developed EV compared with 22 (31.8%) of the 69 untreated subjects (P < 0.0001) and 45 (39.1%) of the 115 non-SVR patients (P < 0.0001). On multivariate analysis, HCV genotype 1b (hazard ratio [HR] 2.40; 95% confidence interval [CI] 1.17-4.90) and baseline model for end-stage liver disease (MELD) score (HR 1.20; 95% CI 1.07-1.35 for 1 point increase) were independent predictors of EV. CONCLUSION: In the long term, the achievement of SVR prevents the development of EV in patients with compensated HCV-induced cirrhosis. Therefore, in these patients, endoscopic surveillance can be safely delayed or avoided. Genotype 1b infection and MELD score identify the subset of patients at higher risk of EV development who need tailored endoscopic surveillance.

Diabetic foot ulcers: Retrospective comparative analysis from Sicily between two eras.

AIM: The aim of this study was to analyze changes in the incidence, management and mortality of DFU in Sicilian Type 2 diabetic patients hospitalized between two eras, i.e. 2008-2013 and 2014-2019. METHODS: We compared the two eras, era1: 2008-13, era2: 2014-19. In era 1, n = 149, and in era 2, n = 181 patients were retrospectively enrolled. RESULTS: In the population hospitalized for DFU in 2008-2013, 59.1% of males and 40.9% of females died, whilst in 2014-2019 65.9% of males and 34.1% of females died. Moderate chronic kidney disease (CKD) was significantly higher in patients that had died than in ones that were alive (33% vs. 43%, p < 0.001), just as CKD was severe (14.5% vs. 4%, p < 0.001). Considering all together the risk factors associated with mortality, at Cox regression multivariate analysis only moderate-severe CKD (OR 1.61, 95% CI 1.07-2.42, p 0.021), age of onset greater than 69 years (OR 2.01, 95% CI 1.37-2.95, p <0.001) and eGFR less than 92 ml/min (OR 2.84, 95% CI 1.51-5.34, p 0.001) were independently associated with risk of death. CONCLUSIONS: Patients with DFU have high mortality and reduced life expectancy. Age at onset of diabetic foot ulcer, eGFR values and CKD are the principal risk factors for mortality.

Perception of the Role of Food and Dietary Modifications in Patients with Inflammatory Bowel Disease: Impact on Lifestyle.

BACKGROUND: Diet has a relevant role in triggering symptoms in inflammatory bowel disease (IBD) from the patients' perspective, but there is gap the between patients' and doctors' perceptions. Few studies have addressed this topic. The aim of this study was to evaluate food habits and nutrition knowledge in a homogeneous cohort of patients with IBD from southern Italy. METHODS: 167 consecutive patients with IBD were recruited. The survey was based on the administration of a semi-structured questionnaire assessing demographics, disease features, dietary behavior, and food intolerance. RESULTS: The majority of patients did not consider food a cause of their disease. However more than 80% changed their diet after the diagnosis and most report an improvement in symptoms. Spiced and seasoned foods, dairy products, vegetables, and fruit were often avoided. A dairy-free diet was adopted by 33.7%. Food choices were based on self-experience and not on medical counselling. Dietary modifications deeply impact on lifestyle. CONCLUSIONS: Most of the patients with IBD set diet and lifestyle on self-experience and give up many foods. This has an impact on psychosocial functioning and can lead to nutritional deficiencies. High quality studies are warranted to assess evidence-based dietary strategies and develop patient-targeted dietary recommendations.

Predictive factors of polycystic ovary syndrome in girls with precocious pubarche.

OBJECTIVE: The aim of this study is to clarify, in girls with premature pubarche (PP), the influence of premature androgenization on the prevalence of polycystic ovary syndrome (PCOS). DESIGN AND PATIENTS: Ninety-nine PP girls, 63 who developed PCOS and 36 who did not develop PCOS, were retrospectively included. Clinical, anthropometric, and metabolic parameters were evaluated at the time of diagnosis of PP and after 10 years from menarche to find predictive factors of PCOS. RESULTS: Young females with PP showed a PCOS prevalence of 64% and showed a higher prevalence of familial history of diabetes (P = 0.004) and a lower prevalence of underweight (P = 0.025) than PP-NO-PCOS. In addition, girls with PP-PCOS showed higher BMI (P < 0.001), waist circumference (P < 0.001), total testosterone (P = 0.026), visceral adiposity index (VAI) (P = 0.013), total cholesterol (P < 0.001), LDL-cholesterol (P < 0.001), non-HDL cholesterol (P < 0.001) and lower age of menarche (P = 0.015), ISI-Matsuda (P < 0.001), DIo (P = 0.002), HDL cholesterol (P = 0.026) than PP-NO-PCOS. Multivariate analysis showed that WC (P = 0.049), ISI-Matsuda (P < 0.001), oral disposition index (DIo) (P < 0.001), VAI (P < 0.001), total testosterone (P < 0.001) and LDL-cholesterol (P < 0.001) are independent predictive factors for PCOS in girls with PP. CONCLUSIONS: Our study established a strong association between multiple risk factors and development of PCOS in PP girls. These risk factors are predominantly related to the regulation of glucose, lipid, and androgen metabolism.

Noninvasive assessment of liver fibrosis in thalassaemia major patients by transient elastography (TE) - lack of interference by iron deposition.

The correlation between liver stiffness, measured by transient elastography, liver fibrosis, using the histological METAVIR score, and iron overload, measured by atomic absorption spectrometry was evaluated in 56 homozygous-beta-thalassaemics. Liver stiffness increased proportionally to liver fibrosis staging (r = 0.70; P > 0.001) independently of liver iron concentration (r = 0.01; P = 0.932). The area under the receiver-operating characteristic curve for prediction of cirrhosis was 0.997 (95% confidence interval [CI]: 0.925-1.000) with cut-off of 13 kPa with 100% sensitivity (95% CI: 69.0-100.0) and 95% specificity (95% CI: 84.2-99.3). Transient elastography is a reliable non-invasive tool for diagnosing advanced liver fibrosis in homozygous-beta-thalassaemics, regardless of the degree of iron overload.

Umbilical hernioplasty in cirrhotic patients with ascites A case control study.

OBJECTIVE: Umbilical hernia is a very frequent pathology, and plastic with prosthetic material is the most frequently used surgical procedure currently used for its repair. In patients with cirrhosis in asciic phase, this pathology is particularly frequent, with a tendency to rapidly increase in size and to become symptomatic. In the past treatment with traditional surgery in cirrhotic patients was considered problematic and was viewed with reserve, and only recently is the surgical approach recommended also in these patients. This study is aimed to evaluate the feasibility and safety of open umbilical hernia plastic with prosthetic material in cirrhotic and ascitic patients. MATERIALS AND METHODS: Our case-control study was conducted on 35 male patients with ascitic phase liver cirrhosis and an equal number of non-cirrhotic patients, all suffering from uncomplicated but symptomatic umbilical hernia, treated surgically consecutively from March 2005 to March 2015. All patients underwent open umbilical hernioplasty with placement of a retromuscular pre-aponeurotic mesh. RESULTS: Of the 35 patients with liver cirrhosis, 20% were classified in Class C, according to Child-Pugh, 28.5% had a MELD score> 15. We have not shown any post-operative mortality. In general, minor complications were observed, more frequent in cirrhotic patients than in healthy controls (p = 0.0315). Among the aforementioned complications the most frequent were hematomas and wound infections, more frequent in cirrhotic patients in Class C according to Child- Pugh and with MELD score> 15 (p <0.005). CONCLUSIONS: Our study shows that umbilical hernia pathology in ascitic cirrhotic patients can be treated surgically with satisfactory results especially in Child-Pugh class A and B patients. The surgical approach of choice must, preferably, be the preferred prosthetic plastic after pre-operative optimization of the coagulation, nutritional and ascitic state.
