PURPOSE OF REVIEW: To describe the current state of knowledge regarding glaucoma patients' eye drop technique, interventions attempting to improve eye drop technique, and methods for assessing eye drop technique. RECENT FINDINGS: In observational studies, between 18.2 and 80% of patients contaminate their eye drop bottle by touching their eye or face, 11.3-60.6% do not instill exactly one drop, and 6.8-37.3% miss the eye with the drop. Factors significantly associated with poorer technique include older age, lack of instruction on eye drop technique, female sex, arthritis, more severe visual field defect, lack of positive reinforcement to take eye drops, lower educational level, low self-efficacy, and being seen at a clinic rather than a private practice...

OBJECTIVES: The Blalock-Taussig shunt (BTS) operation is a cornerstone as initial palliative surgery for congenital heart disease with severely reduced pulmonary blood flow (PBF). The ideal PBF provided by BTS is crucial for an uneventful postoperative course, since excess PBF results in acute distress of the systemic circulation and insufficient PBF requires another BTS surgery. Therefore, the goal of this study was to develop a simple device to control the shunt graft flow percutaneously using a constrictor balloon connected to a subcutaneous port...

This case report describes the management of a term baby, born cyanotic, who was preoperatively diagnosed to have an obstructed total anomalous pulmonary venous drainage (TAPVD) in association with a functionally univentricular heart. An urgent repair of the anomalous pulmonary venous drainage was done, and a modified Blalock-Taussig shunt was constructed. Intraoperative difficulties were encountered when the pulmonary venous confluence was not seen in the usual location in the posterior mediastinal space, anterior to the esophagus...

Sense and antisense peptides, i.e. peptides specified by complementary DNA and RNA sequences, interact with increased probability. Biro, Blalock, Mekler, Root-Bernstein and Siemion investigated the recognition rules of peptide-peptide interaction based on the complementary coding of DNA and RNA sequences in 3'→5' and 5'→3' directions. After more than three decades of theoretical and experimental investigations, the efficiency of this approach to predict peptide-peptide binding has been experimentally verified for more than 50 ligand-receptor systems, and represents a promising field of research...

OBJECTIVE: Aortic pathologies exhibit sexual dimorphism, with aneurysms in both the thoracic and abdominal aorta (ie, abdominal aortic aneurysm [AAA]) exhibiting higher male prevalence. Women have lower prevalence of aneurysms, but when they occur, aneurysms progress rapidly. To define mechanisms for these sex differences, we determined the role of sex chromosome complement and testosterone on the location and progression of angiotensin II (AngII)-induced aortic pathologies. APPROACH AND RESULTS: We used transgenic male mice expressing Sry on an autosome to create Ldlr (low-density lipoprotein receptor)-deficient male mice with an XY or XX sex chromosome complement...

Background -Infants with ductal-dependent pulmonary blood flow may undergo palliation with either a patent ductus arteriosus (PDA) stent or modified Blalock-Taussig (BT) shunt. A balanced multi-center comparison of these two approaches is lacking. Methods -Infants with ductal-dependent pulmonary blood flow, palliated with either PDA stent or BT shunt from 1/08 to 11/15, were reviewed from the four member centers of the Congenital Catheterization Research Collaborative. Outcomes were compared using propensity score adjustment to account for baseline differences between groups...

BACKGROUND: Transplant-free survival for single right ventricle (RV) lesions remains less than 70% at 3 years. Arrhythmia burden, influence of shunt type at Norwood procedure (RV-to-pulmonary artery shunt [RVPAS] versus Blalock-Taussig shunt [BTS]), and implications for mortality risk are not well defined. METHODS: The authors performed a single-center retrospective analysis of patients with single RV lesions enrolled in a prospective study of arrhythmias after congenital heart surgery...

In isolated unilateral ductal origin of a pulmonary artery (DOPA), intervention to establish reperfusion of the affected lung without direct re-anastomosis may lead to pulmonary hypertension (PH) in the contralateral lung. Multicenter retrospective review of patients with unilateral DOPA, who underwent palliation with a ductal stent (DS) or Blalock-Taussig (BT) shunt with subsequent development of PH in the contralateral lung, was conducted. Ten patients (4 females; median weight 3.2 kg, range 2.1-5.2) who underwent DS or BT shunt and developed contralateral PH were identified...

In neonates, the management of ductus dependent pulmonary circulation is challenging. There have been three palliative therapies for this lesion: the modified Blalock-Taussig shunt, ductal stenting and prostaglandin E infusions, for maintaining the ductal patency before definite operations. Debates remain with regard to the indications and disadvantages of three palliative therapies. The aim of this article is to give a brief review of these three palliative therapies.

BACKGROUND: The Modified Blalock-Taussig shunt (MBTS) is the most common palliative operation performed in patients with complex cardiac defects. Postoperative morbidity and mortality rates are high, mainly due to shunt thrombosis and over-shunting. Over-shunting may be difficult to identify postoperatively based on conventional criteria. Since plasma B-type natriuretic peptide (BNP) concentrations correlate with the magnitude of shunting in various left-to-right shunt cardiac defects, we investigated its ability to identify postoperative MBTS over-shunting...

The extracellular matrix (ECM) is a dynamic, bioactive structure critical to organ development, structure and function. Excessive remodeling of the ECM is a hallmark of a variety of inflammatory conditions including vascular disease. Endothelin-1 (ET1) synthesis is understood to promote cardiovascular diseases including acute cardiac transplant rejection; however, the contribution of ECM-derived chemokines (matrikines) to vascular inflammation remains poorly understood. Herein we report that the matrikine acetylated Pro-Gly-Pro (PGP) stimulates vascular inflammation through activation of endothelial CXC Chemokine Receptor 2 (CXCR2) and production of endothelin-1 both in vitro and in vivo...
