The 5-aminosalicylates, especially mesalazine, are the first option in the treatment of mild-to-moderate ulcerative colitis (UC). High rates of remission induction and maintenance have been observed with the new multimatrix (MMX) mesalazine formulation, mainly in patients with distal disease. Our aim was to describe the real-world experience with MMX mesalazine in patients with UC at two tertiary care centers.
A retrospective cohort study was conducted that included 142 patients with confirmed UC diagnosis, analyzed in three study groups 1) oral MMX mesalazine as monotherapy for remission induction, 2) oral MMX mesalazine as monotherapy for remission maintenance, and 3) oral MMX mesalazine plus topical therapy for remission induction.
The frequency of clinical remission induction in group 1 was 80.3%, with biochemical remission of 74.2%. Group 2 had 100% clinical and biochemical remission maintenance. The frequency of clinical remission induction in group 3 was 88.6%, biochemical remission was 85.7%, and topical therapy was suspended in 87.3% at the end of follow-up. No adverse events were documented.
There were high percentages of clinical and biochemical remission in the two corresponding study groups and topical therapy was suspended in the majority of patients in a short follow-up period.

The purpose of this study was to assess the effect of a telehealth-delivered nutritional intervention via telephone in maintenance hemodialysis (HD) patients during the coronavirus outbreak.
This was a multicenter, observational, prospective, and longitudinal study of 156 patients undergoing maintenance HD from 15 dialysis units conducted during the COVID-19 pandemic. We assigned patients to receive dietary counseling through a phone call, according to their biochemical and nutritional parameters. Dry weight, intradialytic weight gain percentage (%IDWG), body mass index, potassium, phosphorus, calcium, calcium/phosphorus product, normalized protein catabolic rate, albumin, and hemoglobin were recorded at baseline and 1month after nutrition counseling.
The prevalence of hyperkalemia and hyperphosphatemia decreased significantly after dietary advice. A statistically significant reduction in serum potassium and phosphorus levels was observed in patients receiving counseling for hyperkalemia and hyperphosphons can improve the clinical and nutritional parameters of HD patients. Consequently, this strategy may be effective for promoting continuous nutritional monitoring in these patients, in particular when conducting a face-to-face option is not crucial.Cystic lesions of the anterior mediastinum represent a well-known group of benign lesions that are relatively common in the general practice, namely in the pediatric age group. In the adult population, multilocular thymic cyst (MTC) plays an important role in occurrence as it presents as a cystic anterior mediastinal mass that clinically may mimic another anterior mediastinal tumor. In general, MTC is of rather unusual occurrence and its histopathological features have been well described in the literature. However, similar histopathological features may also be associated with a gamut of other tumoral conditions that although unrelated may be encountered growing along the walls of these cystic structures. Herein a presentation of the classical MTC and the classical histopathological features of such entity in association with other tumoral conditions will be discussed. It is highly important to underscore that the final interpretation of some of these tumors is based on a thorough evaluation of the cystic lesion and a reasonable sampling for histological evaluation so that the proper interpretation can be reached. Needless to say, the radiological and clinical information of the patients with cystic anterior mediastinal lesions is very important in the final analysis of these cases.Germline inactivating mutations in SMARCA4 (SWI/SNF-related, matrix-associated, actin-dependent regulator of chromatin, subfamily A, member 4) gene encoding for BRG1 (Brahma related gene-1) are the molecular drivers in small cell carcinoma of ovary, hypercalcemic type (SCCOHT) and in malignant rhabdoid tumors (MRT) that occur in the context of rhabdoid tumor predisposition syndrome-type 2. Somatic SMARCA4 mutations and/or loss of BRG1 have been identified in a variety of adult-onset epithelial and mesenchymal neoplasms. Among thoracic tumors, these include subsets of smoking-related non-small cell lung carcinoma (NSCLC) and a relatively rare, newly recognised tumor entity thoracic SMARCA4-deficient undifferentiated tumor (SMARCA4-UT). Less than 100 cases of SMARCA4-UT have been reported to date. They present as large compressive and infiltrative mediastinal, lung and/or pleural masses in middle-aged male smokers. They are undifferentiated tumors composed of sheets of small/epithelioid and/or rhabdoid tumor cells variably expressing epithelial markers and consistently showing loss of BRG1 and the closely related protein, Brahma (BRM). G Protein agonist Frequent expression of stem cell markers (SOX2, CD34, SALL4) is noted. Despite gene expression profiles similar to MRTs and SCCOHT, they show striking genomic overlap with SMARCA4-mutant NSCLC with frequent TP53, STK11, KEAP1, and KRAS mutations, high tumor mutation burden (TMB), and presence of smoking related molecular signatures in tumor cells. SMARCA4-UT show uniformly poor survival and are irresponsive to conventional therapies. Immunotherapy responses are variable but promising, although PDL1 expression appears to be of poor predictive value. Drugs exploiting genetic and epigenetic mechanisms of SMARCA4 antagonism hold promise for future targeted therapies.Over the years the nomenclature of thymomas has been debated regarding the best manner in which these tumors should be grouped. In every schema presented thus far, the main issue has been the presence or lack of lymphocytes and accordingly, the tumors have been place into a specific category. However, even though this concept applies for most of the cases, there are numerous tumors that do not necessarily fit into those categories as either the thymomas show another cellular proliferation associated with the epithelial cells or the epithelial cell themselves are arranged in a pattern that departs from the conventional features of the classic thymoma. Herein we will emphasize those features, which in some circumstances, mainly with small mediastinoscopic biopsies may pose a considerable problem in interpretation. We do consider that the most important issue is to be familiar with the different growth pattern that these tumors may show in order to avoid misdiagnosis. In addition, we consider that regardless of the growth pattern or cellular composition of the tumor, it is highly recommended that these tumors just like any other be carefully sampled and properly stage.
