Maternal and Fetal Expression of ATP-Binding Cassette and Solute Carrier Transporters Involved in the Brain Disposition of Drugs.

Evidence from preclinical and clinical studies demonstrate that pregnancy is a physiological state capable of modifying drug disposition. Factors including increased hepatic metabolism and renal excretion are responsible for impacting disposition, and the role of membrane transporters expressed in biological barriers, including the placental- and blood-brain barriers, has received considerable attention. In this regard, the brain disposition of drugs in the mother and fetus has been the subject of studies attempting to characterize the mechanisms by which pregnancy could alter the expression of ATP-binding cassette (ABC) and solute carrier (SLC) transporters.

Multiprocedural Facial Feminization Surgery: A Review of Complications in a Cohort of 31 Patients.

Objective: Facial feminization surgery (FFS) is instrumental in gender affirmation for transgender patients. Multiprocedural FFS, the combination of multiple facial feminization procedures across multiple depths and planes during one surgery, crosses sterile and nonsterile planes in the oropharynx, nose, and frontal sinus. A closer look at the prevention and management of resulting complications of such reconstruction is necessary.

Nonsurgical Correction of Congenital Ear Deformities: The Relationship Between Age of Presentation and Regression.

Purpose: After 3 weeks of age, studies show ear molding to be unsuccessful due to increased regression rates. Studies have not differentiated success rates based on regression severity; partial regressions may be deemed successful and satisfactory by parents. We examined successful ear molding at different ages of presentation by measuring regression severity and parental satisfaction.

How Soluble Fms-Like Tyrosine Kinase 1 Could Contribute to Blood-Brain Barrier Dysfunction in Preeclampsia?

Preeclampsia is a pregnancy-related syndrome that courses with severe cerebrovascular complications if not properly managed. Findings from pre-clinical and clinical studies have proposed that the imbalance between pro- and anti-angiogenic factors exhibited in preeclampsia is a major component of its pathophysiology. In this regard, measurement of circulating levels of soluble tyrosine kinase-1 similar to fms (sFlt-1), a decoy receptor for vascular endothelial growth factor (VEGF), is a moderately reliable biomarker for the diagnosis of preeclampsia.

Inflammatory capacity of exosomes released in the early stages of acute pancreatitis predicts the severity of the disease.

As acute pancreatitis progresses to the severe form, a life-threatening systemic inflammation is triggered. Although the mechanisms involved in this process are not yet well understood, it has been proposed that circulating exosomes may be involved in the progression of inflammation from the pancreas to distant organs. Here, the inflammatory capacity and protein profile of plasma exosomes obtained during the first 24 h of hospitalization of patients diagnosed with acute pancreatitis were characterized and compared with the final severity of the disease.

Heterogeneity of clinical management of low-grade gastric lymphoma of mucosa-associated lymphoid tissue. An audit of 198 patients in Spain.

Introduction: Cure of Helicobacter pylori infection in patients with gastric lymphoma of mucosa-associated lymphoid tissue (MALT) leads to long-term clinical remission in the initial stages. As it is a rare disease, its management in clinical practice remains largely unknown and heterogeneity of care remains a concern. The aim was to audit the management and evolution of a large series of low-grade gastric MALT lymphomas from thirteen Spanish hospitals.

Accuracy of the Ultra-Rapid Urease Test for diagnosis of Helicobacter pylori infection.

Background: Rapid Urease Test (RUT) is a simple, cheap and relatively fast method for diagnosing Helicobacter pylori infection. It is therefore the preferred method used for patients undergoing gastroscopy. Most kits require 24h to give results.

Protocol for the detection and nutritional management of high-output stomas.

Introduction: An issue of recent research interest is excessive stoma output and its relation to electrolyte abnormalities. Some studies have identified this as a precursor of dehydration and renal dysfunction. A prospective study was performed of the complications associated with high-output stomas, to identify their causes, consequences and management.

Concussion evaluation and management in pediatrics.

Concussions are among the most complex injuries to assess and manage in sports medicine and primary care. Sports concussion in youth has received much attention in recent years because research shows that improperly managed concussion can lead to long-term cognitive deficits and mental health problems. There are several notable risk factors affecting the incidence and severity of concussion in school-age children and adolescents, including a history of a previous concussion.

Accuracy of GastroPanel for the diagnosis of atrophic gastritis.

Background: It has been suggested that GastroPanel might be a useful tool for the diagnosis of chronic atrophic gastritis (CAG) measuring four biomarkers in blood: basal gastrin-17 (G17), pepsinogen I and II (PGI and PGII), and Helicobacter pylori antibodies.

Aim: To determine the accuracy of GastroPanel for the diagnosis of CAG.

Methods: This was a prospective, blinded, multicenter study that included dyspeptic patients.

Efficacy of rifabutin-based triple therapy as second-line treatment to eradicate helicobacter pylori infection.

Background: Rifabutin has been found to be effective in multi-resistant patients after various treatment cycles for Helicobacter pylori (HP) infection, but it has not been analysed as a second-line treatment. Therefore, we seek to compare the effectiveness of a treatment regimen including rifabutin versus conventional quadruple therapy (QT).

Methods: Open clinical trial, randomised and multi-centre, of two treatment protocols: A) Conventional regime -QT- (omeprazole 20 mg bid, bismuth citrate 120 mg qid, tetracycline 500 mg qid and metronidazole 500 mg tid); B) Experimental one -OAR- (omeprazole 20 mg bid, amoxicillin 1 gr bid, and rifabutin 150 mg bid), both taken orally for 7 days, in patients with HP infection for whom first-line treatment had failed.
