Abstract Objectives: To investigate survival and freedom from reintervention after aortic coarctation repair in Maltese patients and to compare cardiovascular mortality in coarctation repair survivors with that in the general population.
Design: All 72 aortic coarctation patients with any type of repair, born by end-1997 and logged in the local database were included. Trends in timing and type of repair were determined by comparing patients born before and after 1985. Kaplan-Meier analyses of survival and reintervention-free survival were performed on the 59 repair survivors with complete follow-up data (mean follow-up 26.13 ± 9.62 (range 1.05–44.55 years). Cardiovascular mortality in repair survivors… More >

Abstract Objectives: To determine overall and reintervention-free survival for repaired Maltese tetralogy of Fallot patients and to investigate the potential impact of gender, age at repair, genetic syndromes, previous palliation, and type of repair on these outcomes.
Design: All 130 tetralogy of Fallot patients born before the end of 1997 included in the local database were extracted. Surgical repair type, age at repair and operative survival were analyzed among the 103/130 repaired patients. Kaplan–Meier survival analyses were performed on the 75 repair survivors with complete follow-up data (mean follow-up 26.37 ± 9.27 (range 9.95–51.21) years).
Results: Patients born after 1985 were… More >

Abstract Importance: There are no well-established noninvasive biomarkers for identifying patients at risk for poor outcome after surgery for congenital heart disease. Few studies have assessed prognostic accuracy of cerebral tissue oxygenation index (cTOI) measured by near infrared spectroscopy (NIRS).
Objective: To assess the utility of noninvasive NIRS monitoring as a predictor of outcomes after neonatal cardiac surgery through measurement of cTOI. To examine the utility of noninvasive NIRS monitoring in combination with lactate concentration and inotropic score in prediction of outcomes after neonatal cardiac surgery.
Design: Prospective longitudinal cohort study.
Setting: Operating room and cardiac intensive care unit, Children’s National… More >

Abstract Objective: Infants with single ventricle physiology typically undergo cardiac catheterization prior to superior cavopulmonary anastomosis (SCPA) to assess operative suitability. Predictors of poor outcome at sea level include elevated pulmonary artery pressure (mPAP), indexed pulmonary vascular resistance (PVRi), age <3 months, significant atrioventricular valve regurgitation, among others. Increased altitude has vasoconstrictive effects on the pulmonary vasculature, which may affect pre-SCPA hemodynamics and outcomes. The goal of this study was to determine the predictive value of pre-SCPA catheterization data with regard to reaching Fontan palliation at altitude.
Design: A retrospective review revealed 150 patients who underwent pre-SCPA catheterization over a 10-year… More >

Abstract Objective: Limited information is known on how right ventricular function affects outcomes after stage 2 palliation. We evaluated the impact of different right ventricular indices prior to stage 2 palliation on morbidity and mortality.
Design: Retrospective study design.
Setting: Pediatric Heart Network Single Ventricle Reconstruction Trial Public Data Set.
Patient: Any variant of stage 1 palliation and all anatomic hypoplastic left heart syndrome variants in the trial were evaluated. Echocardiograms prior to stage 2 palliation were analyzed and compared between those who failed and those who survived.
Intervention: None.
Outcome measures: Mortality was defined as death, listed for transplant, or… More >

Abstract Chirostoma jordani is a native annual species inhabiting lacustrine waters of the Central Mexico Plateau. It is widely distributed and is currently facing high environmental pressures. Five experiments were performed to study the reproductive performance of this species. Four of the experiments were conducted in 270-L indoor recirculation tanks. Two males and one female at the first stage of reproduction were included in each test. A photoperiod of 14 light hours and 10 dark hours was used. In a fifth experiment, 10 females and 15 males were kept in an outdoor 3,000-L recirculation tank under natural photoperiod. The number of… More >

Abstract Cologania broussonetii (Balb.) DC. stands out as valuable perennial, native forage that grows in northwestern Argentina, Cordoba hills and San Luis Province. The objectives of this study were to establish the vegetative and reproductive structures in function of the strategies and survival tactics of Cologania broussonetii. The specimens were collected in the Pan de Azúcar loaf mountain, Córdoba, and in the experimental plots of the FCA, UNC, and were then deposited in the Herbarium ACOR and in the Seed Collection. Seedlings were obtained from germination assays. Cross section cuts were performed on the survival structures of adult plants, and on… More >

Abstract Dicliptera squarrosa Nees, “canario rojo”, “coral de campo” or “ajicillo”, is a perennial native herb of the north, center and east of Argentina. It is cited as an ornamental, apiarian, emergency forage plant, and as a glyphosate-tolerant weed. The objectives were to characterize the seed and seedling of D. squarrosa and to establish the relationships with the structures that ensure its survival. The materials were treated with the conventional methodology to perform morphological studies, using stereoscopically and optical microscopy. The germination assays were carried out to determine the germination percentage and the germination type. The weight of 1000 seeds was… More >

Abstract The Argentine arid Patagonia, in general, and ‘La Payunia’ ecosystem in particular, are important areas for conservation due to the high number of endemic species. However, this region presents a high level of degradation as a result of human activities. Thus, ecological rehabilitation strategies need to be implemented to recover certain areas. The main objectives of this study were to (1) evaluate the reintroduction of two selected native species in severely degraded areas, and (2) determine if the survival and growth of an endemic shrub species, Senna arnottiana, increase when it is associated with a perennial grass, Pappostipa speciosa. These… More >
