Ulcerative colitis (UC) is a chronic relapsing and remitting disease requiring frequent hospitalization. Biologics have become the recommended initial therapy for Biologics in patients with moderate to severe UC. Our aim was to estimate the changes in Nationwide Healthcare utilization and assess predictive factors of 30-day readmission, morbidity and mortality of UC.

This is a retrospective observational study analyzing the Nationwide Readmission database from 2016 to 2017 using ICD-10 codes. The primary outcomes of the study were to assess the predictors of 30-day readmission in patients with UC.

Of the 54 138 adult patients with a primary diagnosis of UC, 13.2% were readmitted within 30 days of index hospitalization. The mortality rate (1.4 vs. 0.3%, P < 0.01), length of stay (7 vs. 4.9 days, P < 0.01) and hospital cost ($62 552 vs. $46 971, P < 0.01) were higher on readmission as compared to index hospitalization. https://www.selleckchem.com/products/Mizoribine.html We identified multiple patient-related factors (age <65years, men, VTE, protein calorie malnutrition, electrolyte imbalance, anemia, anxiety and alcohol abuse), hospital-related factors (teaching hospitals, high quintile hospitals), as independent predictors of 30-day UC readmission. Colonoscopy, Cannabis use, and colectomy were associated with decreased odds of 30-day readmission. The most common cause of UC was septicemia.

This is the largest nationwide study demonstrating predictors of 30-day readmission, mortality and morbidity associated with UC. Identification and amelioration of these risk factors will decrease readmission rate and mortality amongst UC patients.

Serum transglutaminase antibodies (tTGs) are used for celiac disease screening and to monitor celiac disease patients on a gluten-free diet (GFD). The need for histology of duodenal biopsies to assess mucosal healing after a GFD is still a matter of debate. We evaluated whether tTGs are adequate to detect the persistence of histological lesions of duodenal mucosa in celiac patients after a GFD.

In total 253 patients with histological diagnosis of celiac disease according to Marsh criteria, both at the time of diagnosis (T0) and 18-24 months after starting a GFD (T2), were included. tTGs were evaluated both at T0 and T2; endomysial antibodies (EMAs) only at T0.

At T0, 9.2% of patients had both tTG and EMA negative values, despite the evidence of duodenal lesions 33.3% of Marsh 1, 14.3% of Marsh 2 and 5.2% of Marsh 3. At T2, tTGs were negative in 77.6% of patients 82.2% of Marsh 0, 79.8% of Marsh 1, 70.0% of Marsh 2 and 59.1% of Marsh 3. At T2, approximately 60% of patients with the persistence of mucosal atrophy had negative tTGs. At T0, tTG median values were lower in patients with Marsh 1 and Marsh 2 than patients with Marsh 3 (P < 0.001), whereas no difference was found at T2 regardless of Marsh's grade (P = 0.4).

The results of our study highlight how histologic evaluation of duodenal biopsies remains the gold standard for both celiac disease diagnosis and the evaluation of mucosal recovery after 18-24 months of a GFD.

In the last years, advances in functional and genetic testing have improved the diagnostic and therapeutic approach to immune dysregulation syndromes. CTLA-4 deficiency is a rare disease with variable phenotype, ranging from absence of symptoms to severe multisystem manifestations and complications. We describe a rare case of CTLA-4 deficiency in a boy with gastric cancer, very early onset inflammatory bowel disease and polyautoimmunity, the second-ever reported in the literature with the same characteristics. A 17-year-old boy was referred to Bambino Gesù Children's Hospital of Rome, a tertiary care center, for a gastric mass and a long-term history of very early onset inflammatory bowel disease, diabetes mellitus type 1, polyarthritis and psoriasis. Histology of gastric biopsies revealed the presence of neoplastic signet ring cells. Imaging staging showed localized cancer; therefore, the patient underwent subtotal gastrectomy with termino-lateral gastro-jejunal anastomosis. Immunological work up and genetic testing by next-generation sequencing panels for primary immunodeficiencies led to the diagnosis of CTLA-4 deficiency. Good disease control was obtained with the administration of Abatacept. The patient experienced an asymptomatic SARS-CoV-2 infection without any concern. Eighteen months after treatment initiation, the patient is alive and well. Immunologic and genetic testing, such as next-generation sequencing, should always be part of the diagnostic approach to patients with complex immune dysregulation syndrome, severe clinical course, poor response to treatments or cancer. The early recognition of the monogenic disease is the key for disease management and targeted therapy.
Acute kidney injury (AKI) in a patient with cirrhosis has high short-term mortality. Midodrine has shown promising results in the treatment of AKI-hepatorenal syndrome (HRS-AKI).

To compare midodrine and albumin versus albumin alone for the secondary prophylaxis of HRS-AKI.

Open labeled, nonrandomized, pilot study. Patients with a diagnosis of HRS-AKI were recruited after complete recovery. Patients were given midodrine daily (15 mg) and injection albumin infusion 20 g weekly in group-A (Gp-A) and injection albumin 20 g weekly with no midodrine in group-B (Gp-B). The primary endpoint was the recurrence of AKI-HRS, and the secondary endpoint was ascites tap in 2-month period.

A total of 42 patients were enrolled in Gp-A, n = 22, and Gp-B, n = 20. There was no significant difference between the groups (Gp-A vs. Gp-B) in terms of age, model stage liver disease, Child-Turcotte-Pugh score and serum creatinine at inclusion (1.27 ± 0.1 vs. 1.22 ± 0.2 mg/dL). During follow up ten patients (50%) in Gp-B and four patients (18%) in Gp-A develop HRS-AKI (P = 0.04). The mean number of ascites tap was significantly higher in Gp-B compared to Gp-A (2.6 ± 0.5 vs. 1.9 ± 0.5) in 2 months. There was a significant increase in mean arterial pressure in Gp-A compared to Gp-B on days 7, 15, 30, 45 and 60. There was a significant difference in mean arterial pressure at day 7 in patients who developed HRS-AKI versus those who did not develop HRS-AKI [(n = 14, 65.5 ± 5.5) vs. (n = 28,74.6 ± 9.2 mm Hg), P = 0.02].

Midodrine along with albumin infusion, is helpful in the secondary prophylaxis of HRS-AKI and reduces the number of ascites tap. However, a large randomized study is required for further validation.

There is still room for improvement in the methods used to achieve complete polyp resection. The aim of this study was to develop a cold snare polypectomy technique that will reliably result in resections containing the muscularis mucosae and the lateral polyp margins.

Nonpedunculated polyps ≤10 mm were resected using a dedicated cold snare with the goal of creating a mucosal defect approximately 1 cm in dia. The completeness of resection of the lateral and vertical polyp margins was examined histologically.

The cases of 201 patients (mean age 67 ± 13 years; 115 men) with 500 eligible polyps were enrolled. The mean polyp size was 6.1 ± 1.8 mm (range 1-10 mm). The mean mucosal defect size immediately after resection was 7.7 ± 2.5 mm (range 3-15 mm). Overall, the complete resection rate in which the lateral and vertical margins were free from the neoplasia tissue was 92% (417/454, 95% CI, 89-94); in the remaining 8% of cases, the vertical margins showed complete resection but the lateral margins could not be evaluated due to the fragmentation of resected polyps. A mucosal defect ≥7 mm predicted complete resection of the mucosal layer containing the muscularis mucosae.

Complete mucosal layer resection of nonpedunculated colorectal polyps ≤10 mm was reliably achieved using a cold snare technique that produced a mucosal defect ≥7 mm in dia.

Squamous cell carcinoma is the most common cancer of the oral cavity. When the tumor invades the bone tissue, the prognostic and survival rates decrease a lot, and the treatment becomes more aggressive, with several damages to the patient and health system. Many of the molecular mechanisms of bone invasion process are not understood yet, but it is already known that one of central processes of tumor evolution - adjacent tissues invasion and metastasis - is a large spectrum of phenotypic changes in epithelial cells to mesenchymal, in a process named as epithelial-mesenchymal transition (EMT). Loss of E-cadherin, an important epithelial cell adhesion protein, is a hallmark of this phenomenon. The objective of this retrospective study is to evaluate the expression of E-cadherin protein, comparing its distribution with clinical characteristics of the patients and possibly relation to EMT.

Sixty-two cases with respective clinical data were analyzed by comparing immunohistochemical, H and E staining, and clinicorse patient's prognosis.
Hydrocephalus is a common comorbidity among the newborns, with myelomeningocele (MMC) and ventriculoperitoneal (VP) shunts being frequently used for the treatment of such patients. In this study, we aimed to compare the effectiveness of antibiotic-free and antibiotic-coated shunts to reduce the rate of shunt infection in patients with hydrocephalus and accompanying MMC.

116 patients with hydrocephalus and MMC who were treated with VP shunts were included in the study. Shunt infection rates among antibiotic-free and antibiotic-coated shunts were compared.

Of the 116 patients included in the study, 39 had antibiotic-coated shunts and 77 had antibiotic-free shunts. Shunt infection developed in 4 of the 39 cases treated with antibiotic-coated shunts and in 5 of the 77 cases treated with shunts without antibiotics. No significant statistical difference was found between antibiotic-coated and antibiotic-free VP shunts in terms of shunt infection (p = 0.450, p > 0.05).

In patients with MMC, using VP shunts containing antibiotics was found not to have a protective effect in preventing shunt infection. Whether the sac is intact or ruptured does not affect this result.
