Introduction
Zonulin is a protein that plays a role in the reversible regulation of epithelial permeability. As zonulin is released in large amounts into the intestinal lumen, it disrupts the integrity of the tight junctions and causes continuous migration of antigens to the submucosa. Consequently, it can trigger inflammatory processes and severe immune reactions. In severe cases, SARS-CoV-2 may have a major impact on the clinical manifestations of the disease by directly or indirectly affecting intestinal cells and triggering systemic inflammation. Therefore, our study aimed to investigate the role of one of the possible mediators, zonulin, in the severity of the COVID-19 infection.
Methods
Thirty COVID-19 patients and 35 healthy controls were included in the study. Blood samples were taken from the patients on the 1st, 4th, and 8th days of hospitalization. Serum zonulin levels were determined by enzyme-linked immunosorbent assay (ELISA). Complete blood count (white blood
Background and aims
Diabetic foot ulcer location is a known independent predictor for cure with a better healing gradient proximal to distal. Although advanced age is one of the main factors associated with greater diabetic foot ulcer severity, there are no studies evaluating diabetic foot ulcer location specifically in the elderly population in an outpatient setting. This study evaluated diabetic foot ulcer location and age-group interactions in diabetic foot presentation.
Methods
A retrospective cohort study including adult patients with diabetic foot ulcers observed on their first visit to our center's Diabetic Foot Unit in 2018, divided into younger adults (YA) (18 to 64 years) and older adults (OA) (≥65 years).
Results
A total of 435 patients were included in the study with 159 (36.6%) in the YA, and 276 (63.4%) in the OA group.
Neuro-ischemic diabetic foot ulcers were more frequent in the OA group (71.4% vs 43.4%, p<0.001). The number of patients with a histor
Anxiety and depression are amongst the most prevalent mental health problems. Their pattern of comorbidity may inform about their etiology and effective treatment, but such research is sparse. Here, we document long-term prognosis of affective caseness (high probability of being a clinical case) of anxiety and depression, their comorbidity, and a no-caseness condition at three time-points across six years, and identify the most common prognoses of these four conditions. Longitudinal population-based data were collected from 1,837 participants in 2010, 2013 and 2016. Based on the Hospital Anxiety and Depression Scale they formed the four groups of anxiety, depression and comorbidity caseness, and no caseness at baseline. The three-year associations show that it was most common to recover when being an anxiety, depression or comorbidity caseness (36.8 − 59.4%), and when not being a caseness to remain so (89.2%). It was also rather common to remain in the same c
Background
Biliary atresia (BA) is a rare but severe cause of obliterative cholangiopathy in neonates. Its incidence differs worldwide varying from 5/100,000 to 32/100,000 live births. The highest incidence is seen in Asia and the Pacific region. Diagnosing this disease is difficult in its early stages; thus, screening is necessary to avoid serious complications that can be minimized with early intervention during the first few months of life. Currently, although there are no medical treatments for BA, once the diagnosis is confirmed, the Kasai procedure may be a treatment option. The earlier the Kasai surgery is performed, the higher the success rate. Liver transplantation may be needed if the operation fails. This study aimed to determine the incidence of BA and the factors influencing the outcomes of the Kasai procedure at King Abdulaziz University Hospital, Jeddah, Saudi Arabia.
Methodology
This retrospective cohort study was conducted in the Pediatric Department at King A
