INTRODUCTION AND OBJECTIVES Abnormal serum iron studies are seen in a third or more of patients with chronic hepatitis C infection (HCV), where they have been linked to accelerated fibrosis progression and increased risk of hepatocellular carcinoma and sometimes lead to concern for coexisting hereditary hemochromatosis. The aim of this study was to assess the effect of HCV eradication in patients with abnormal serum iron studies prior to treatment with direct-acting antiviral agents (DAAs). PATIENTS HCV-infected subjects with iron studies obtained before and after successful treatment with DAAs were identified (n=27). All had one or more abnormal iron test before treatment. RESULTS Following HCV eradication, serum iron, transferrin-iron saturation and ferritin levels decreased significantly (pre- versus post-treatment, p1000ng/mL. Elimination of HCV infection was associated with a significant reduction in post-treatment ferritin levels even among subjects whose ferritin levels were within normal limits at baseline. Risk factors for other conditions associated with abnormal iron status were present in the few cases in which iron studies failed to normalize following DAA treatment. CONCLUSIONS Eradication of HCV infection restores normal iron status in most patients with abnormal iron tests, including those whose baseline parameters are suggestive of hemochromatosis. Uveitis is a heterogeneous collection of inflammatory diseases of the intraocular uveal tissues and adjacent structures, and they collectively are a significant cause of visual morbidity. In recent years, investigating the contribution of the gut microbiota to autoimmunity, including the development of uveitis, has gained interest. Decreased disease severity has been observed in both the induced experimental autoimmune model of uveitis and the spontaneous RI61H model of uveitis in mice treated with oral broad-spectrum antibiotics and raised in germ-free conditions, implicating a role for the gut microbiota in the development of disease in these models. Also, in support of these findings are the differences in the composition of the microbiota that have been reported in uveitis patients. Proposed mechanisms accounting for the microbiota triggering uveitis include antigenic mimicry and dysbiosis leading to dysregulation of the immune system. An improved understanding of these mechanisms will facilitate potential therapeutic approaches including alteration of the microbiota with probiotic treatment and fecal microbiota transplants.

MATERIAL AND METHODS The sample comprised 46 Class II malocclusion patients divided into two groups. Patients with Class II malocclusion based on the ANB angle and plaster model analyses, needing non-extraction orthodontic treatment, absence of mandibular crowding and no previous orthodontic treatment were eligible to be selected. Group 1 consisted of 25 patients treated with cervical headgear (CH) followed by fixed appliances for a mean period of 3.26 years and group 2 consisted of 21 patients treated with the Jones Jig (JJ) appliance for a mean of 4.29 years. Lateral cephalograms were evaluated at the beginning and at the end of orthodontic treatment. For intergroup comparisons, t and Mann-Whitney tests were performed. RESULTS The cervical headgear group produced significantly greater maxillary anterior displacement restriction (SNA; CH -0.97°±1.33; JJ 0.07°±1.73; P=0.025), apical base discrepancy improvement (ANB; CH -1.52°±1.25; JJ 0.36°±1.46; P=0.006), FMA reduction (CH -0.78°±2.68; JJ 1.07°±2.84; P=0.028) and distal mandibular molar angulation (Md6.PM; CH 6.97°±3.66; JJ 2.77°±6.87; P=0.013) than the Jones Jig group. CONCLUSIONS Both distalizers followed by fixed appliances were effective to correct Class II malocclusion. The cervical headgear group presented skeletal effects with less treatment time and there were no significant intergroup differences regarding soft tissue changes. PURPOSE Interventional cardiology procedures, during which live images are acquired, involve exposure to x-rays. The use of fluoroscopy can cause high radiation doses to patients and operators because of the prolonged duration of x-ray emission. For this reason, special attention and constant vigilance represent challenges for commissions and groups of experts in the field. The purpose of this study is to establish local diagnostic reference levels (DRLs) for these procedures, to improve radiological practice, and to optimize radiation doses. METHODS This work was carried out in two university hospitals and two private medical facilities in Rabat, the capital of Morocco, during the period 2017-2018. The study concerns 657 interventional cardiology procedures (457 coronary angiography [CA] and 200 percutaneous transluminal coronary angioplasty [PTCA]), performed by 11 cardiologists on different installations in 5 catheterization rooms. The data collected for each procedure were patient age, height and weight, dosimeter indicators in terms of dose area product (PKA), total air kerma at the reference point (Kar), fluoroscopy time (FT), and the number of frames, together with the primary beam parameters as kV and total mAs. The proposed DRLs were set from the 75th percentile of the PKA and FT. RESULTS The mean of PKA for CA and PTCA procedures were 29.2 Gy∗cm2 and 70.4 Gy∗cm2, respectively, the mean of fluoroscopy time were 4.0 min and 12.17 min for 334 and 685 frames, respectively. Results for the local DRLs were 37.3 and 87.1 Gy cm2 for PKA and 4.48 and 16.15 min for FT, corresponding to CA and PTCA procedures. CONCLUSION This work focuses on proposing local DRLs in Morocco for CA and PTCA procedures. The results show that the values found conform with those of international studies. selleck inhibitor INTRODUCTION AND OBJECTIVES We assessed the long-term hemodynamic performance of transcatheter heart valve (THV) by paired transthoracic echocardiography (TTE), and the incidence, characteristics and factors associated with THV structural valve degeneration (SVD). METHODS A total of 212 patients who underwent transcatheter aortic valve replacement and had a potential follow-up >5 years with at least 1 TTE ≥ 1-year postprocedure were included. All patients had a TTE at 1 to 5 years and 36 had another one at 6 to 10 years. SVD was defined as subclinical (increase >10mmHg in mean transvalvular gradient+decrease >0.3cm2 in valve area and/or new-onset mild or moderate aortic regurgitation) and clinically relevant (increase> 20mmHg in mean transvalvular gradient+decrease> 0.6cm2 in valve area and/or new-onset moderate-to-severe aortic regurgitation). selleck inhibitor Fifteen patients had a transesophageal echocardiography at the time of SVD diagnosis, and 85 an opportunistic computed tomography examination at 1 (0.5-2) years. RESULTS Transvalvular mean gradient increased and valve area decreased over time (P less then .
