In chronic inflammatory lung disorders such as chronic obstructive pulmonary disease (COPD), the concurrent organ-specific and systemic inflammatory responses lead to airway remodelling and vascular dysfunction. Although a major common risk factor for COPD, cigarette smoke alone cannot explain the progression of this disease; there is increasing evidence that genetic predisposition also plays a role in COPD susceptibility and progression. A key enzyme in chronic lung inflammation is leukotriene A4 hydrolase (LTA4H)...

Management of pulmonary atresia with ventricular septal defect (PA-VSD) in the neonatal period presents numerous challenges. Endovascular stenting of the ductus arteriosus or of a collateral vessel in ductal-dependent pulmonary circulation as an alternative to the Blalock-Taussig (BT) shunt has become increasingly popular in the last decades. The utilization of the reverse Szabo (anchor-wire) technique for single collateral vessel stenting in a case of PA-VSD is described.

A 30-year-old female with tricuspid valve atresia, ventricular septal defect, and atrial septal defect had a neonatal modified Blalock Taussig shunt and a Fontan-Björk operation performed at five years of age. She did well initially but progressively developed signs of systemic congestion due to severe homograft stenosis and underwent successful percutaneous implantation of a Melody(®) pulmonary valve (Medtronic, Minneapolis, MN, USA) in the "tricuspid" position.

In this study, we describe an infant case of pulmonary atresia with intact ventricular septum associated with ventriculo-coronary arterial communication for which a modified Blalock-Taussig shunt operation was performed. He experienced repeated myocardial ischaemic attacks. Further examination revealed pulmonary sequestration in the right lower lobe. He therefore underwent a bidirectional Glenn operation and coil occlusion of the feeding arteries. His myocardial ischaemic attacks subsequently improved.

Chronic obstructive pulmonary disease (COPD) is the third leading cause of death in the US. The majority of COPD patients have symptoms of chronic bronchitis, which lacks specific therapies. A major impediment to therapeutic development has been the absence of animal models that recapitulate key clinical and pathologic features of human disease. Ferrets are well suited for the investigation of the significance of respiratory diseases, given prior data indicating similarities to human airway physiology and submucosal gland distribution...

BACKGROUND: For neonates with critical left ventricular outflow tract obstruction (LVOTO), hybrid procedures are an alternative to the Norwood stage 1 procedure. Despite perceived advantages, however, outcomes are not well defined. Therefore, we compared outcomes after stage 1 hybrid and Norwood procedures. METHODS: In a critical LVOTO inception cohort (2005-2014; 20 institutions), a total of 564 neonates underwent stage 1 palliation with the Norwood operation with a modified Blalock-Taussig shunt (NW-BT; n = 232; 41%), Norwood operation with a right ventricle-to-pulmonary artery conduit (NW-RVPA; n = 222; 39%), or a hybrid procedure (n = 110; 20%)...

Right atrial isomerism and pulmonary atresia combined with major aortopulmonary collateral arteries are very rare. Surgical treatment becomes more challenging when an extracardiac total anomalous pulmonary venous connection (TAPVC) requiring surgical repair neonatally is also present. We describe a successful staged Fontan operation for a neonate with a single ventricle, right atrial isomerism, pulmonary atresia with major aortopulmonary collateral arteries, a small central pulmonary artery and a supracardiac TAPVC...

The unilateral absence of a proximal pulmonary artery (UAPPA) is rare and is most frequently accompanied by cardiovascular anomalies such as tetralogy of Fallot or septal defects. We report a patient with truncus arteriosus with UAPPA in which we performed a two-stage surgical repair. During the first palliative operation, a right modified Blalock-Taussig shunt was constructed to develop the hypoplastic right pulmonary artery. At 10 months, the patient underwent patch closure of a ventricular septal defect with integration of both pulmonary arteries, and reconstruction of the right ventricular outflow tract using a conduit...

We present a case of an ex-30 week premature male infant diagnosed postnatally with Tetralogy of Fallot, hemitruncus, and discontinuous pulmonary arteries (PAs) at 6 days of life. The patient was diagnosed by echocardiography, and the diagnosis was confirmed on subsequent dual-energy chest CT angiogram. In our patient, the left PA arose directly from the aorta, whereas the right PA originated normally from the right ventricular outflow tract. At 9 days of life, he underwent successful surgical palliation with placement of a modified Blalock-Taussig (aortopulmonary) shunt from the base of the left subclavian artery to the anomalously connected left PA along with anastomosis together of the right and left branch PAs to establish continuity with the main PA...

This study examined whether social-emotional coping skills moderate the association between parental mental health symptoms and adolescent disordered eating attitudes and behaviors in a clinical sample of adolescents with internalizing and/or externalizing symptoms. Fifty-nine adolescent-parent dyads (N = 118 total participants) recruited from a metropolitan area in the Northeastern United States completed assessments at baseline and 12-month follow-up. Generally, higher parental depression and anxiety were only found to be associated with greater disordered eating attitudes and behaviors among adolescents who reported poorer (versus stronger) emotional awareness/expression skills and less (versus greater) ability to regulate emotions...

Modified Blalock-Taussig shunt (mBTS) obstruction can be life-threatening, especially when it represents the only source of pulmonary blood flow. Current therapeutic options to reverse obstruction include surgical shunt revision/replacement, interventional endovascular procedures including balloon angioplasty and/or stent placement, and a combination of local and systemic thrombolytic therapy. We report two cases of acute mBTS thrombosis successfully treated with systemic recombinant tissue plasminogen activator in infants convalescing after cardiac surgery when the clinical status and resources precluded traditionally described rescue therapies...

OBJECTIVE: Fuzzy-trace theory is a dual-process model of memory, reasoning, judgment, and decision making that contrasts with traditional expectancy-value approaches. We review the literature applying fuzzy-trace theory to health with 3 aims: evaluating whether the theory's basic distinctions have been validated empirically in the domain of health; determining whether these distinctions are useful in assessing, explaining, and predicting health-related psychological processes; and determining whether the theory can be used to improve health judgments, decisions, or behaviors, especially compared to other approaches...

PURPOSE: To assess changes in inmates' misuse of substances from pre- to post-incarceration. METHODS: In Study 1, professionals (n = 162) and laypersons (n = 50) predicted how jail inmates' substance misuse would change from pre-incarceration to post-release. In Study 2, a longitudinal study of 305 jail inmates, we examined actual changes in substance use and dependence from pre-incarceration to the first year post-incarceration, as well as whether changes varied as a function of demographic, criminal justice, treatment, and personality factors...

OBJECTIVES: Fuzzy trace theory was used to examine the effect of information concerning medication benefits and side-effects on willingness to use a hypothetical medication. METHODS: Participants (N=999) were recruited via Amazon Mechanical Turk. Using 3×5 experimental research design, each participant viewed information about medication side effects in 1 of 3 formats and information about medication benefits in 1 of 5 formats. For both side-effects and benefits, one format presented only non-numeric information and the remaining formats presented numeric information...

OBJECTIVES: The Norwood procedure for hypoplastic left heart syndrome (HLHS) is performed either via a right ventricle-to-pulmonary artery (RVPA) conduit or a modified Blalock-Taussig (MBT) shunt. Cardiac magnetic resonance (CMR) data was used to assess the effects of the RVPA conduit on ventricular shape and function through a computational analysis of anatomy and assessment of indices of strain. METHODS: A retrospective analysis of 93 CMR scans of subjects with HLHS was performed (59 with MBT shunt, 34 with RVPA conduit), incorporating data at varying stages of surgery from two congenital centres...

OBJECTIVE: In recent years, the median sternotomy approach with cardiopulmonary bypass has been increasingly chosen when systemic-pulmonary shunt surgery is performed as initial palliation for congenital heart diseases with decreased pulmonary blood flow to secure a stable surgical field and to maintain a stable circulation and oxygen supply. Since 2007, this strategy has been applied in our institute. This time, we examine the advantage and disadvantage of this procedure by evaluating the intraoperative and postoperative courses...

OBJECTIVES: We investigated the effect of balloon pulmonary valvuloplasty (BPV) as a palliative procedure for patients with tetralogy of Fallot (TOF). METHODS: This was a retrospective single-center study conducted between 2008 and 2014. We classified patients into three groups according to palliation: treatment with BPV (group I), with a Blalock-Taussig shunt (group II), and with infundibulectomy (group III). The growth of the pulmonary valve (PV) annulus and need for transannular patching (TAP) during total correction were compared between groups...
