A mixture of organic acids and thymol protects primary chicken intestinal epithelial cells from Clostridium perfringens infection in vitro
Necrotic enteritis causes economic losses estimated to be up to 6 billion US dollars per year. Clinical and sub-clinical infections in poultry are also both correlated with decreased growth and feed efficiency. Moreover, in a context of increased antibiotic resistance, feed additives with enhanced antimicrobial properties are a useful and increasingly needed strategy. In this study, the protective effects of a blend of thymol and organic acids against the effects of Clostridium perfringens type A (CP) on chicken intestinal epithelial cells were investigated and compared to bacitracin, a widely used antibiotic in poultry production. Primary chicken intestinal epithelial cells were challenged with CP for a total time of 3h to assess the beneficial effect of two doses of citric acid, dodecanoic acid, and thymol-containing blend, and compare them with bacitracin. During the challenge different parameters were recorded, such as transepithelial electrical resistance, cell viability, mRNA expression, and reactive oxygen species production. CP induced inflammation with cytokine production and loss of epithelial barrier integrity. It was also able to induce reactive oxygen species production and increase the caspase expression leading to cellular death. The high dose of the blend acted similarly to bacitracin, preventing the disruptive effects of CP and inducing also an increase in zonula occludens-1 mRNA expression. The low dose only partially prevented the disruptive effects of CP but successfully reduced the associated inflammation. This study shows that the usage of thymol combined with two organic acids can protect primary chicken intestinal epithelial cells from CP-induced damages creating a valid candidate to substitute or adjuvate the antibiotic treatment against necrotic enteritis
The Expanded Risk Score in Rheumatoid Arthritis: performance of a disease-specific calculator in comparison with the traditional prediction scores in the assessment of the 10-year risk of cardiovascular disease in patients with rheumatoid arthritis
The increased risk of cardiovascular disease has emerged as a major issue in patients with rheumatoid arthritis – it has been estimated that the cardiovascular disease burden in rheumatoid arthritis is comparable to that of diabetes mellitus
Apparent diffusion coefficient values in borderline breast lesions upgraded and not upgraded at definitive histopathological examination after surgical excision
Purpose: The study aims were to evaluate if the apparent diffusion coefficient (ADC) value could distinguish between breast lesions classified as B3 at core needle biopsy (CNB) that show or do not show atypia or malignancy at definitive histopathological examination (DHE) after surgical excision. Material and methods: From January 2013 to December 2017, 141 patients with a B3 breast lesion underwent magnetic resonance imaging and were included in the study. The ADC value was assessed drawing a ROI outlining the entire lesion, evaluating the mean () and minimum ADC values (). Results: Both and ADCmin values showed a statistically significant difference between B3 lesions without and with malignancy or, for B3a lesions, atypia at DHE. They both showed a statistically significant difference also between B3a lesions without or with atypia or malignancy at DHE, but only (not ) showed statistically significant difference between B3b lesions without or with malignancy at DHE. Conclusions: The ADC value could help distinguish between B3a lesions without or with atypia/malignancy at DHE after surgical excision and between B3b lesions without or with malignancy at DHE. Therefore, it could be used to help guide the diagnostic-therapeutic pathway of these lesions, particularly of B3a lesion
Prevalence and clinical outcome of hepatic haemangioma with specific reference to the risk of rupture: a large retrospective cross-sectional study.
BACKGROUND:
Prevalence and incidence of hepatic haemangioma are estimated from autopsy series only. Although benign and generally asymptomatic, hepatic haemangioma can cause serious complications.
AIMS:
The aim of the study was to assess the prevalence of hepatic haemangioma and to attempt to quantify the risk of major complications such as spontaneous rupture.
METHODS:
We retrospectively analyzed the radiology database of a Regional University Hospital over a 7-year period: the radiological records of 83,181 patients who had an abdominal computed tomography or magnetic resonance scan were reviewed. Diagnoses made at imaging were reviewed and related to clinical course.
RESULTS:
Hepatic haemangioma was diagnosed in 2071 patients (2.5% prevalence). In 226 patients (10.9%), haemangioma had diameter of 4 cm or more (giant haemangioma). The risk of bleeding was assessed on patients without concomitant malignancies. Spontaneous bleeding occurred in 5/1067 patients (0.47%). All 5 patients had giant haemangioma: 4 had exophytic lesions and presented with haemoperitoneum; 1 with centrally located tumour experienced intrahepatic bleeding.
CONCLUSION:
Giant haemangiomas have a low but relevant risk of rupture (3.2% in this series), particularly when peripherally located and exophytic. Surgery might be considered in these cases
Effectiveness and tolerability of Poliprotect, a natural mucosal protective agent for gastroesophageal reflux disease and dyspepsia: Surveys from patients, physicians, and pharmacists
Background: Gastroesophageal reflux disease (GERD) and functional dyspepsia (FD) are very common in the general population. GERD prevalence is considerably high in pregnant women, and it increases at a young age, alongside obesity. Mucosal protective agents (MPAs) are over-the-counter (OTC) treatments for FD and GERD commonly used alone or as add-on therapy to proton pump inhibitors (PPIs). Real-world data through surveys allow a clinical evaluation of marketed products that also complies with the new regulation on substance-based medical devices (SBMDs).Aim: The study aimed to evaluate perceived effectiveness, safety, and pattern of usage among patients, physicians, and pharmacists of the natural MPA Poliprotect, as assessed by a validated survey methodology.Methods: Questionnaire repeatability was first assessed, resulting in the intraclass correlation coefficient agreement level >0.9 in the three validation cohorts of physicians, pharmacists, and patients. All questions were closed multiple-choice, allowing measuring variations in frequency, quality, or magnitude of effect on a 5-point Likert-like verbal scale.Results: Three different surveys were performed in Italy and Spain on a total of 3,471 physicians, including 77 gastroenterologists, 848 patients, and 146 pharmacists who had an experience with Poliprotect in the previous year. Over 90% of general practitioners (GPs) rated Poliprotect effectiveness as good/excellent in controlling pyrosis, 80% for epigastric pain, and approximately 70% for digestion difficulties. GPs reported Poliprotect as very or extremely useful as an alternative to PPIs (73%) and for pregnancy-associated GERD symptoms (61%), almost unanimously (99.5%) reporting an excellent to good tolerability; 79% of the gastroenterologists answered to be extremely or very satisfied with the improvement of typical GERD symptoms, whereas improvement of dyspepsia and pregnancy- and breast-feeding-associated GERD symptoms was rated as highly satisfactory for 69, 52, and 62%, respectively, among GI specialists. Its use because of painful dyspeptic symptoms was reported by over 80% of patients, who rated symptom relief as excellent/good, and reported a marked quality-of-life improvement in 73% and in 65% of their answers, respectively. The product was used as monotherapy by 63% of patients. Conclusion: Large-scale, validated surveys support the safety and effectiveness of Poliprotect in the treatment of common functional upper GI disorders
New insertable cardiac monitors show high diagnostic yield and good safety profile in real-world clinical practice. results from the international prospective observational SMART Registry
Aims: Insertable cardiac monitors (ICMs) are indicated for long-term monitoring of unexplained syncope or palpitations, and for detection of bradycardia, ventricular tachycardia, and/or atrial fibrillation (AF). The aim of our study was to evaluate the safety and clinical value associated with a new generation ICM (Confirm Rx™, Abbott, Illinois, USA), featuring a new remote monitoring system based on smartphone patient applications. Methods and results: The SMART Registry is an international prospective observational study. The main endpoints were ICM safety (incidence of serious adverse device and procedure-related events (SADEs) at 1 month), ICM clinical value (incidence of device-detected true arrhythmias and of clinical diagnoses and interventions), and patient-reported experience measurements (PREMs). A total of 1400 subjects were enrolled. ICM indications included syncope (49.1%), AF (18.8%), unexplained palpitations (13.6%), risk of ventricular arrhythmia (6.6%), and cryptogenic stroke (6.0%). Freedom from SADEs at 1 month was 99.4% (95% Confidence Interval: 98.8-99.7%). In the 6-month monitoring period, the ICM detected true cardiac arrhythmias in 45.7% of patients and led to clinical interventions in a relevant proportion of patients; in particular, a pacemaker implant was performed after bradycardia detection in 8.9% of subjects who received an ICM for syncope and oral anticoagulation therapy was indicated after AF detection in 15.7% of subjects with cryptogenic stroke. PREMs showed that 78.2% of subjects were satisfied with the remote monitoring patient app. Conclusion: The evaluated ICM is associated with an excellent safety profile and high diagnostic yield. Patients reported positive experiences associated with the use of their smartphone for the device remote monitoring
