EUS-guided tissue acquisition in patients with solid pseudopapillary neoplasms of the pancreas.

Objectives: Endoscopic ultrasound-guided tissue acquisition (EUS-TA) has been the most common method used for the preoperative cytopathological diagnosis of solid tumors of the pancreas. There are only a few reported cases about the role of endoscopic ultrasound-guided fine needle biopsy (EUS-FNB) in the pre-operative diagnosis of solid pseudopapillary neoplasms (SPN). This study aimed to evaluate the diagnostic yield of EUS-TA,including endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) andEUS-FNB, in patients with SPN.

Humoral response to different SARS-CoV-2 vaccines in orthotopic liver transplant recipients.

Background: The safety and efficacy data of the different types of available vaccines is still needed. The goal of the present analysis was to evaluate the humoral response to the COVID-19 vaccines in orthotopic liver transplant (OLT) recipients.

Methods: Participants were included from February to September 2021.

The neutrophil-lymphocyte ratio as a predictor of steroid response in patients with severe ulcerative colitis: a retrospective cohort study.

In this study we assessed the neutrophil-lymphocyte ratio (NLR) as a predictor of steroid non-response (SNR) in patients with acute severe ulcerative colitis and found a NLR on day 3 (NLR-3) >6.1 as a suitable cutoff point to identify SNR (OR 3.44, 95%CI 1.

NAFLD determined by Dallas Steatosis Index is associated with poor outcomes in COVID-19 pneumonia: a cohort study.

Coronavirus disease 2019 is a worldwide health challenge. Liver steatosis diagnosis based on imaging studies has been implicated in poor outcomes of COVID-19 pneumonia, but results are inconsistent. The Dallas Steatosis Index (DSI) is an available calculator developed to identify patients with non-alcoholic fatty liver disease (NAFLD).

Pancreatogenic Diabetes, 2 Onset Forms and Lack of Metabolic Syndrome Components Differentiate It From Type 2 Diabetes.

Objectives: We compared pancreatogenic (DM3c) and type 2 diabetes mellitus.

Methods: We compared age-, sex-, and diabetes mellitus duration-matched DM3c cases (n = 142) and type 2 diabetes mellitus (n = 142). Pancreatogenic diabetes was considered when it appeared after the diagnosis of pancreatitis or after pancreatic surgery.

Low Thoracic Skeletal Muscle Area Is Not Associated With Negative Outcomes in Patients With COVID-19.

Objective: Sarcopenia has been related to negative outcomes in different clinical scenarios from critical illness to chronic conditions. The aim of this study was to verify whether there was an association between low skeletal muscle index and in-hospital mortality, intensive care unit admission, and invasive mechanical ventilation need in hospitalized patients with COVID-19.

Design: This was a retrospective cohort study of a referral center for COVID-19.

Steroid-responsive pancreatitides.

Autoimmune pancreatitis has received considerable attention, especially due to the marked effect of corticosteroid therapy on its clinical course. Knowledge, especially regarding type 1 autoimmune pancreatitis, has significantly increased over the last decades, and despite significant differences in pathophysiology and outcomes, both type 1 and 2 autoimmune pancreatitis are still considered different types of the same disease. Some have proposed a different nomenclature reflecting these differences.

Translation of gastric disease progression at gene level expression.

is associated with the development of several lesions in the human stomach. This chronic infection produces gastritis, which can progress to intestinal metaplasia and gastric cancer. To date, there is very little information regarding gene-expression in the different phases of progression caused by chronic infection.

Retroperitoneal fibrosis. Steroid treatment response seems to depend on its association to IgG4 related disease.

Retroperitoneal fibrosis (RF) is part of a rare fibrosclerotic disorder. Oral steroids are the initial treatment. Steroid combination with other immunosupressants is used in refractory cases.

Abnormal Cardiovascular Findings in Acute Pancreatitis: Are They Associated with Disease Severity?

Background: Acute pancreatitis (AP), a disease that commonly requires in-hospital treatment, has been associated with a high incidence of abnormal cardiovascular findings (ACFs). We conducted a prospective study to explore the association of these findings with severity of the disease.

Methods: Adult patients with AP diagnosis were prospectively enrolled in an observational study during an 8-month period in a tertiary care center.

Adherence to a Gluten-Free Diet in Mexican Subjects with Gluten-Related Disorders: A High Prevalence of Inadvertent Gluten Intake.

Background: The rate of compliance with a gluten-free diet in patients with gluten-related disorders is unknown in most Latin American countries.

Objective: To study the adherence to a gluten-free diet of Mexican individuals with celiac disease and nonceliac gluten sensitivity at the time of their first medical and nutritional consultation at a tertiary referral center.

Methods: A cross-sectional study was performed.

Serous Cystadenomas Follow a Benign and Asymptomatic Course and Do Not Present a Significant Size Change During Follow-Up.

Background: Serous cystadenoma is a benign pancreatic cystic neoplasm. Conservative management is favored. We studied the clinical characteristics and course of serous cystadenoma in patients undergoing surgery or conservative management only at an academic referral center.

Decrease in the Prevalence of Pancreatitis Associated with Primary Hyperparathyroidism: Experience at a Tertiary Referral Center.

Background: Hypercalcemia is a rare but well recognized cause of acute and chronic pancreatitis. Hypercalcemia-related pancreatitis is mainly caused by primary hyperparathyroidism. The prevalence of pancreatitis in hyperparathyroidism varies worldwide and additional disease-modifying factors may play a role in its development.

[Clinical characteristics associated to resectability in patients with tumors of the ampulla of Vater in a third-level hospital in Mexico: an 18-year experience].

Background: Ampulla of Vater's tumors (AVT) are rare and account for 0.2% of neoplasia in necropsies. The stage, comorbidities and surgical experience are crucial for prognosis.

Association of the HLA-DRB1*0701 allele with perinuclear anti-neutrophil cytoplasmatic antibodies in Mexican patients with severe ulcerative colitis.

Aim: To determine the association between the HLA-DRB1 alleles and perinuclear anti-neutrophil cytoplasmatic antibodies (p-ANCA) positive in Mexican patients with ulcerative colitis (UC).

Methods: Ninety Mexican mestizo patients (45 females) with UC, confirmed by biopsy, were studied. High resolution HLA typing was performed by PCR-SSO reverse dot blot and PCR-SSP.
