Split Knockoffs for Multiple Comparisons: Controlling the Directional False Discovery Rate [PDF]

, 2023
Multiple comparisons in hypothesis testing often encounter structural constraints in various applications. For instance, in structural Magnetic Resonance Imaging for Alzheimer's Disease, the focus extends beyond examining atrophic brain regions to include comparisons of anatomically adjacent regions.

Prevalence of hepatitis B virus amongst refugees, asylum seekers and internally displaced persons in low‐ and middle‐income countries: A systematic review

Journal of Viral Hepatitis, Volume 30, Issue 1, Page 4-18, January 2023., 2023
Abstract Hepatitis B, caused by the hepatitis B virus (HBV), is a global public health issue that affects 290 million people worldwide. Most people with hepatitis B are in low‐ and middle‐income countries (LMIC), where health systems and resources are often constrained.

Interleukin-17A promotes parietal cell atrophy by inducing apoptosis [PDF]

, 2018
Background & Aims: Atrophic gastritis caused by chronic inflammation in the gastric mucosa leads to the loss of gastric glandular cells, including acid-secreting parietal cells.

Characteristics of Superficial Gastric Neoplasms Detected Not by White Light Imaging but by Linked Color Imaging. [PDF]

JGH Open
ABSTRACT Background and Aims Laser endoscopy has a linked color imaging (LCI) mode which has been reported to be superior to white light imaging (WLI) in detecting early gastric cancer (EGC). In this study, we retrospectively investigated the characteristics of superficial gastric neoplasms detected not by WLI but by LCI.

Comparison of the human gastric microbiota in hypochlorhydric states arising as a result of Helicobacter pylori-induced atrophic gastritis, autoimmune atrophic gastritis and proton pump inhibitor use.

PLoS Pathogens, 2017
Several conditions associated with reduced gastric acid secretion confer an altered risk of developing a gastric malignancy. Helicobacter pylori-induced atrophic gastritis predisposes to gastric adenocarcinoma, autoimmune atrophic gastritis is a ...

Diagnostic values of serum levels of pepsinogens and gastrin-17 for screening gastritis and gastric cancer in a high risk area in Northern Iran [PDF]

, 2014
Background: Gastric cancer (GC) is the second cause of cancer related death in the world. It may develop by progression from its precancerous condition, called gastric atrophy (GA) due to gastritis.

Treatment of helicobacter pylori infection in atrophic gastritis [PDF]

, 2018
Helicobacter pylori (Hp) is a major human pathogen causing chronic, progressive gastric mucosal damage and is linked to gastric atrophy and cancer. Hp-positive individuals constitute the major reservoir for transmission of infection.

Is Screening for and Surveillance of Atrophic Gastritis Advisable? [PDF]

Digestive Diseases, 2007
Gastric cancer remains a leading cause of cancer-related deaths in many parts of the world. At present, prevention seems to be the most effective means to reduce its the incidence and mortality rate. Gastric atrophy is considered the first relevant step in the histogenesis of gastric adenocarcinoma.

Two distinct aetiologies of cardia cancer, evidence from premorbid serological markers of gastric atrophy and Helicobacter pylori status [PDF]

, 2007
Background: Non-cardia gastric adenocarcinoma is positively associated with Helicobacter pylori infection and atrophic gastritis. The role of H pylori infection and atrophic gastritis in cardia cancer is unclear.

Risk Assessment of Gastric Cancer and Precancerous Condition Using Serum Pepsinogen and H. Pylori Antibody Test

Central Asian Journal of Medical Sciences, 2023
Objectives: We aimed to determine serum PGs (serum pepsinogens) and H. Pylori IgG in atrophic gastritis and gastric cancer patients and evaluate the gastric cancer risk.
