Differential expression of serum miR-486 and miR-25 in ulcerative colitis and Crohn's disease: Correlations with disease activity, extent, and location.

Novel reliable biomarkers of inflammatory bowel disease (IBD) are clinically imperative due to potential limitations of endoscopic techniques. MicroRNAs (miRNAs) have emerged as non-invasive biomarkers of IBD; however, the full disease-specific miRNAs signature for IBD subtypes remains elusive. We evaluated the diagnostic role of circulating miR-486 and miR-25 in IBD patients and their potential ability to discriminate IBD subtypes; ulcerative colitis (UC) and Crohn's disease (CD).

Prevalence and correlates of mental health difficulties following the beirut port explosion: The roles of mentalizing and resilience.

Objective: Research has consistently highlighted an increased prevalence of mental health problems, such posttraumatic stress disorder (PTSD), depression, and anxiety, following both man-made and natural disasters. Mentalizing and resilience have been previously identified as potential protective factors against the onset of mental health difficulties following such events.

Method: This study first identified the prevalence of PTSD symptoms, depression, anxiety, and stress and subsequently assessed mentalizing abilities and resilience as predictors of PTSD symptomatology in a sample of 521 Lebanese participants following the Beirut Port explosion on August 4, 2020.

Placental control of drug delivery.

The placenta serves as the interface between the maternal and fetal circulations and regulates the transfer of oxygen, nutrients, and waste products. When exogenous substances are present in the maternal bloodstream-whether from environmental contact, occupational exposure, medication, or drug abuse-the extent to which this exposure affects the fetus is determined by transport and biotransformation processes in the placental barrier. Advances in drug delivery strategies are expected to improve the treatment of maternal and fetal diseases encountered during pregnancy.

Study of Adiponectin Level in Diabetic Adolescent Girls in Relation to Glycemic Control and Complication of Diabetes.

Aim: To study the relation between adiponectin level with glycemic control and complication of diabetes.

Patients And Methods: The study included 40 female adolescent type 1 diabetic patients and 40 healthy volunteers of the same age and sex. Blood sample was taken for assessment of glycosylated hemoglobin, lipid profile and adiponectine.

Manganese superoxide dismutase alanine to valine polymorphism and risk of neuropathy and nephropathy in Egyptian type 1 diabetic patients.

Unlabelled: Oxidative stress, characterized by a marked increase in the level of oxygen free radicals (OFR), has been implicated in the development of diabetic microangiopathic complications, such as diabetic neuropathy (DN) and nephropathy (DP). Antioxidant enzymes may protect against the rapid onset and progression of microangiopathy, by reducing the excess of OFR and peroxides. Mutations and polymorphisms in genes encoding such enzymes may therefore result in a predisposition to this disorder.

Action plans in asthma.

Background: Action plans are recommended for most patients with persistent asthma to reduce the morbidity associated with this chronic disease. Unfortunately, despite these recommendations, this tool remains underused.

Methods: The authors conducted a descriptive study at the asthma clinic of a tertiary care centre to determine the number of asthmatic patients presenting to a respiratory physician (new reference or follow-up visit) who possessed an individualized, written action plan, and to evaluate the patients' level of confidence and perceived efficacy toward their plans.

A teenager with angiographically normal epicardial coronary arteries and acute myocardial infarction after butane inhalation.

The most common cause of death among volatile substance abusers is sudden cardiac death. To the best of our knowledge, butane-induced myocardial infarction is a rare presentation among teenagers. We report on a 14-year-old male student who sustained cardiopulmonary arrest after sniffing seven canisters of butane.

Abnormal glucose tolerance in Egyptian beta-thalassemic patients: possible association with genotyping.

Background: Type 1 diabetes mellitus (DM) is a frequent complication in patients with beta-thalassemia. It is believed to be due to the damage inflicted by iron overload of the pancreatic beta cells. Liver disorders and genetic influences seem to be additional predisposing factors.

Urinary excretion of n-acetyl-beta-D-glucosaminidase and retinol binding protein as alternative indicators of nephropathy in patients with type 1 diabetes mellitus.

Diabetic nephropathy (DN) is usually characterized by glomerular dysfunction, with microalbuminuria as an early indicator. Urinary excretion of smaller molecular weight proteins such as n-acetyl-beta-glucosaminidase (beta-NAG) and retinol binding protein (RBP) indicate proximal tubular dysfunction, and may identify diabetic patients at risk of developing diabetic nephropathy. In a trial to assess renal tubular function, urinary excretion of beta-NAG (by colorimetric assay) and RBP (by ELISA) were determined in 59 type 1 diabetic patients (mean age 15 +/- 3.

5- to 16-year follow-up following splenectomy in chronic immune thrombocytopenic purpura in children.

Unlabelled: The long-term outcome after splenectomy in children with chronic immune thrombocytopenic purpura (ITP) has not been widely analyzed. We reviewed the medical records of 288 children and adolescents with chronic ITP between 1980 and 1996: 112 were splenectomized; 59 were steroid resistant and 42 were steroid dependent, and 11 were managed with repeated courses of intravenous immunoglobulin (IVIG). All had platelet counts (PCs) <30 x 10(9)/l with frequent bleeding episodes or persistent thrombocytopenia <10 x 10(9)/l.
