REVIEW
Henri Roukoz, David G Benditt
Atrial arrhythmias are a common complication after lung transplant (LT), occurring in about 16-46% of LT patients early postoperatively, and in about 14% during longer-term follow-up. They have a significant impact on postoperative in-hospital length of stay and may have an impact on overall mortality. In this report, we review the incidence and risk factors of post lung transplant AA, their pathogenesis and their impact on short- and long-term outcomes. Pharmacological management options are reviewed. In brief, early atrial arrhythmias tend to be mostly atrial fibrillation and are treated acutely with a rate control strategy followed if needed by rhythm control for 4-6 weeks...

Acute and chronic bioassays provide essential basis for establishment of environmental quality standards. The effects of Cu on a pulmonate snail, Physa acuta, were investigated at a number of sublethal and lethal endpoints. Cu exposure suppressed movement and triggered an escape response in P. acuta at low and high concentrations, respectively, exerting acute toxic effects on adult snails exposed to a 96 h LC50 of 23.8 μg L(-1). Following 16 d exposure of Cu to the egg masses, successful hatching decreased with increasing Cu concentration...

Chemical coding of stomatogastric nervous system (STNS) and enteric nervous system (ENS) of midgut and hindgut in the snail Megalobulimus abbreviatus was investigated using histochemistry, histofluorescence, and immunohistochemistry. The gastrointestinal plexuses, constituted by intrinsic neurons and fibers originating from the subesophageal ganglia and/or STNS, showed intense acetylcholinesterase (AChE) and nicotinamide adenine dinucleotide diaphorase (NADPHd) activity. The enteric neurons and fibers with AChE activity are scattered in the submucosa and between both muscular layers of gastrointestinal tract, whereas NADPHd neurons and fibers are more abundant between muscular layers than in the submucosa...

BACKGROUND: Pulmonary artery aneurysms constitute <1% of aneurysms occurring in the thoracic cavity. Congenital cardiac defects are responsible for the majority (>50%) of cases, however, pulmonary artery aneurysm is a rare sequelae of pulmonary tuberculosis reported in about 5% of patients with chronic cavitary tuberculosis on autopsy. The natural history of this potentially fatal condition remains poorly understood and guidelines for optimal management are controversial. CASE PRESENTATION: A 24-year-old man, a nursing student of African descent, was referred to us from an up-country regional hospital with a 4-week history of recurrent episodes of breathlessness, awareness of heartbeats and coughing blood 3 weeks after completing a 6-month course of anti-tuberculosis drugs...

Objectives Sedative agents are occasionally used to enable echocardiographic examination when screening cats for heart disease, such as hypertrophic cardiomyopathy (HCM). Owing to their haemodynamic effects, sedative agents may alter echocardiographic measurements. The aim of the study was to evaluate the effects of the sedative combination dexmedetomidine and buprenorphine on echocardiographic variables, blood pressure (BP) and heart rate (HR) in healthy cats. Methods Fifty healthy, client-owned cats were prospectively recruited and included after physical examination...

Cross-sectional studies reveal an association between tuberculosis (TB) and chronic airflow obstruction, but cannot adequately address confounding. We hypothesised that treated pulmonary TB is an independent risk factor for chronic airflow obstruction. The Pulmones Post TB cohort study enrolled participants from Lima, Peru, aged 10-70 years with a history of drug-susceptible (DS)- or multidrug-resistant (MDR)-TB who had completed treatment and were clinically cured. Unexposed participants without TB were randomly selected from the same districts...

The pulmonate gastropods, Phallomedusa solida (Martens, 1878) and Ophicardelus ornatus (Férussac, 1821), exhibit characteristic distributional patterns at the upper intertidal zones in estuarine mangrove and saltmarsh habitats on the eastern Australian coast. Past studies suggested inundation condition, soil salinity, and percent of vegetation cover were responsible for these patterns. In this study, the role of environmental parameters, food availability, physical stress, and predation pressure in determining the distributional patterns of these gastropods was evaluated along transects spanning saltmarsh, mangrove, and the ecotone habitats...

Temperature affects the physiology and life-history of ectothermic animals, often increasing metabolic rate and decreasing body size. Oxygen limitation has been put forward as a mechanism to explain thermal responses of body size and the ability to survive stress. However the time-scales involved in growth performance and heat tolerance differ radically. In order to increase our understanding of oxygen and temperature effects on body size and heat tolerance and the time scale involved, we reared Lymnaea stagnalis under six combinations of temperature and oxygen tension from hatching up to an age of 300 days and recorded shell length during this whole period...

Carcinoid syndrome is the constellation of symptoms mediated by humoral factors produced by some carcinoid tumors. It consists primarily of vasomotor symptoms, gastrointestinal hypermotility, hypotension, and bronchospasm, due to the production and release of vasoactive substances. Carcinoid heart disease occurs in more than 50% of patients with carcinoid syndrome; in some cases, it represents the initial manifestation of the disease. We report the case of a 75-year-old woman with a metastatic neuroendocrine tumor admitted to the emergency room for fatigue and heart failure...

Lung’s own properties make that nutritional support, besides covering the requirements can modulate its infl ammatory response. Lung tissue has a low glucose stock. Fatty acids are the main energy producer of type II pneumocytes, which use them in order to form phospholipids, essential for surfactant whose creation and release decrease in acute lung injury (ALI). Glutamine is a good substratum for endocrine cells and type II pneumocytes. Due to high nutritional risk, it is important its assessments in disorders as COPD and acute respiratory distress syndrome (ADRS)...

Williams-Beuren syndrome is a multisystem genetic disorder caused by hemizygous deletion on chromosome 7q11.23, encompassing about 28 genes including the elastin gene, ELN. Cardiovascular abnormalities are frequent and are related to elastin insufficiency. These abnormalities include supravalvular aortic stenosis (SVAS) in 70% of case, pulmonic valve stenosis, and renal artery stenosis. Definitive therapy for supravalvar aortic stenosis consists of surgical correction of the arteriopathies. Outcomes after surgical correction of SVAS depend on the extent of the arteriopathy and the presence of other associated lesions...

In ecotoxicology, analytical compartmentalization analysis can be used to better understand metal sequestration and detoxification. Metals are typically found in two main compartments, biologically detoxified metal (BDM) and metal sensitive fractions (MSF). The purpose of this study was to analyze the subcellular distribution of cadmium (Cd) in Lymnaea stagnalis. Adult snails were exposed to three concentrations of Cd for 56 days as part of a global ring test for L. stagnalis. At the end of the 56-day exposure, organisms were separated in two sections (viscera and foot)...
