Anterior cingulate cortex activation during attentional control as a transdiagnostic marker of psychotherapy response: a randomized clinical trial.

Anterior cingulate cortex (ACC) response during attentional control in the context of task-irrelevant emotional faces is a promising biomarker of cognitive behavioral therapy (CBT) outcome in patients with social anxiety disorder (SAD). However, it is unclear whether this biomarker extends to major depressive disorder (MDD) and is specific to CBT outcome. In the current study, 72 unmedicated patients with SAD (n = 39) or MDD (n = 33) completed a validated emotional interference paradigm during functional magnetic resonance imaging before treatment.

A Pilot Study of Iyengar Yoga for Pediatric Obesity: Effects on Gait and Emotional Functioning.

Obesity negatively impacts the kinematics and kinetics of the lower extremities in children and adolescents. Although yoga has the potential to provide several distinct benefits for children with obesity, this is the first study to examine the benefits of yoga for gait (primary outcome) in youths with obesity. Secondary outcomes included health-related quality of life (HRQoL), physical activity, and pain.

Distinct Influences of Anxiety and Pain Catastrophizing on Functional Outcomes in Children and Adolescents With Chronic Pain.

Objectives: Examine whether anxiety and pain catastrophizing are distinct constructs in relation to functional outcomes in pediatric chronic pain, and whether they differentially predict functional outcomes based on age.

Methods: In all, 725 youth (191 children, 534 adolescents) with chronic pain completed measures of pain characteristics, anxiety, pain catastrophizing, functional disability, and health-related quality of life (HRQOL). Structural equation modeling was used to examine interrelationships.

Utility of the PedsQL™ family impact module: assessing the psychometric properties in a community sample.

Purpose: Research on families coping with pediatric chronic illnesses has established that children and parents are affected by the illness. Therefore, optimal assessment of parent and family functioning is clinically important. The PedsQL™ family impact module (FIM) assesses parents' health-related quality of life (HRQOL) and family functioning.

Parents' initial perceptions of multidisciplinary care for pediatric chronic pain.

Chronic and recurrent pain is experienced by many children and adolescents. Treatment of chronic pain using a multidisciplinary approach has been found to be effective for treatment of chronic pain. Parent satisfaction with treatment and treatment providers highly correlates to children's treatment adherence.

[Ventricular conduction disorder in presence of dead myocardium].

In the presence of an advanced degree left bundle branch block (LBBB) with an extensive "Jumping wave" phenomenon, the septal activation abnormally spreading originates septal electromotive forces of greater duration and consequently more important than normal ones. The coexistence of an inactive anteroseptal myocardium with an advanced degree block causes the phenomenon of "Jumping wave" begins in postero-septal regions. Therefore the external left electrodes see the first ventricular activation fronts moving away and register Q waves.

[On the actual nomenclature of myocardial infarcts].

Certain criteria are examined for infarctions currents defined as inferior or inferolateral. To do this, certain considerations on the anatomical aspects of isolated and in situ heart are laid out. The topographical relationship of the in situ heart with other adjacent thoracic organs is described.

[Uncomplicated and complicated myocardial peripheral blocks].

Septal necrosis + peripheral left blocks. Because of an extensive septal necrosis, the manifestation of the initial ventricular activation forces decreases in the precordial leads. With left bifascicular block (LASB + LPSB), the first ventricular activation forces become more evident and the electrical signs of septal necrosis can be concealed.

Antiarrhythmic and arrhythmogenic action of inosine in experimental ventricular tachyarrhythmias.

Objective: To study the possible action of inosine on experimental ventricular tachyarrhythmias.

Material And Methods: We used 92 mongrel dogs weighing 13 kg-17 kg, anesthetized with 30 mg/kg sodium pentobarbital applied intravenously. Myocardial lesions were induced by injecting 1 ml-1.

[Left posterolateral extensive myocardial infarct. An electroanatomical comparison].

A complete ECG thoracic circle allows exploring some heart structures not explored by the conventional electrocardiogram. It provides a direct indication on the location of the damaged myocardium. In fact, posterolateral infarctions can be limited to the inferior third of the left ventricle or can cover the entire free left ventricular wall from the base up to the heart apex and can be univentricular or biventricular.

Peripheral heart blocks associated with myocardial infarcts: clinical diagnosis based on experimental findings.

Septal necrosis + peripheral left blocks. Because of an extensive septal necrosis, the manifestation of the initial ventricular activation forces decreases in the precordial leads. With left bifascicular block (LASB + LPSB), the first ventricular activation forces become more evident and the electrical signs of septal necrosis can be concealed.

[On the diagnostic value of indirect electrocadiographic signs of left posterolateral basal infarction].

The left basal posterolateral infarct does not give pathological Q waves nor ventricular QS complexes in the low lateral leads V5 and V6. For that, the increased voltage of R waves in the lead V2 and or transitional leads V3 and V4, constitutes only an indirect sign of the presence of dead myocardium in the left posterolateral basal regions. Naturally, in these cases, a differential diagnosis with left ventricular or biventricular hypertrophy is mandatory.

[Electrical manifestations of dead myocardium associated to proximal blocks of intermediate degree].

The electrical manifestation of dead myocardium associated to incomplete bundle branch block, i.e., with a limited "jumping wave" phenomenon, are exposed.

[On the electrical manifestations of some heart diseases associated with ventricular preexcitation].

Electro-Vectorcardiographic curves, corresponding some heart diseases, must be analyzed in the light of the ventricular depolarization sequence, as well as on the heart's position and rotation. A more than 30-msec interval between the end of the initial slurring (delta) and the vertex of the R wave in the left unipolar leads or the main axis of the vectorcardiographic ventricular curves, allows us to infer the coexistence of left ventricular hypertrophy. On the other hand, segmental irregularities or distorsions of the electric curves suggest the presence of a limited myocardial zone unable to be activated.

[An ECG-anatomical comparison in a case of Williams' syndrome].

A case of Williams' syndrome in a 22 years old man, is described. Clinical data, as well as those of laboratory and of imageneology study, are reported. An electro-anatomical comparison permitted to verify the value of electrocardiographic signs of enlargement of the four heart chambers, due to a mixed overload.

[On the ventricular arrhythmias in Chagasic chronic cardiomyopathy].

Some authors have shown a high prevalence of electric circuits localized in the epicardium in Chagasic cardiomyopathy. Other authors have found in these patients, during electric mapping, mid-diastolic potentials and earlier myocardial activation in epicardial regions than in the endocardium. In a previous study, we found electrocardiographic signs of subepicardial ischemia in 66% of seropositive Chagasic patients against 16% of seronegative Chagasic ones.

[Electrocardiographic features of right ventricular hypertrophy in chronic cor pulmonale].

The electrophysiological criteria for diagnosing right ventricular hypertrophy, characteristic of chronic cor pulmonale, are described. Right ventricular hypertrophy due to a sustained systolic overload can be global or regional. In the first situation, as for example, an idiopathic pulmonary hypertension, the magnitude and manifestation of all the main vectors resulting from the depolarization of this ventricle are increased: Ils (septal), llr (parietal), and Illr (basal).

[On Q-wave and non-Q wave myocardial infarcts].

Much has been said, and is still being said, on Q-wave and non-Q wave myocardial infarcts, trying to relate this electrocardiographic behavior with the culprit coronary arteries and the location of the damaged myocardium. However, it seems logic to bear in mind that the presence or absence of abnormal Q waves depends on the relation established between the zone of damaged myocardium and the width of the electrical endocardium. It must be recalled that the presence of normal Q waves is possible in leads that seem to move away from the first vector of ventricular activation.

Dynamic electrocardiographic changes after aborted sudden death in a patient with Brugada syndrome and rate-dependent right bundle branch block.

A 37-year-old man with Brugada syndrome and dynamic changes of the ST-segment morphology observed after an episode of aborted sudden death is described. On admission, after 3 syncopal episodes during nighttime, his electrocardiogram showed right bundle branch block (RBBB) with a J-point elevation of 0.6 mV in lead V 2 .

Risk factors, echocardiographic patterns, and outcomes in patients with acute ventricular septal rupture during myocardial infarction.

Ventricular septal rupture (VSR), which can complicate an acute myocardial infarction (MI), carries a high mortality rate. Because precordial and transesophageal echocardiography can identify the type of rupture and assess right ventricular (RV) function at the patient's bedside, we examined the prognostic significance of echocardiographic patterns in postinfarct VSR by postulating that complex rupture and RV involvement carry a worse prognosis. Seventeen patients (10 men; mean age 66 years) who had confirmed postinfarct VSR underwent precordial and transesophageal echocardiography followed by coronary angiography.

[Early and late effects of adenosine in experimental ventricular tachycardia].

Introduction And Objective: To study the action of adenosine in experimental ventricular tachycardia.

Material And Method: We studied 173 mongrel dogs weighing 13-17 kg anesthetized with 30 mg/kg sodium pentobarbital given intravenously. Myocardial lesions were provoked with the injection of 1-1.

[Septal and parietal dead myocardium with peripheral monofascicular blocks].

We describe the electrical manifestations of dead left septal, left and right parietal myocardium and those of biventricular location, reviewing the electrocardiographic signs of the isolated left and right peripheral blocks. We also describe the electrical manifestations of dead myocardium accompanied by a left anterior subdivision block (LASB) and a left posterior subdivision block (LPSB). These ventricular conduction disorders can reduce or conceal the electrical manifestation of the dead zone.

[On metabolic therapeutics G-I-K in surgery of cardiac patients].

The basic principles of the metabolic therapeutics with glucose-insulin-potassium solutions, already proposed by Dr. Demetrio Sodi Pallares, are exposed. Chronologic succession of this treatment during the preoperative, transoperative and postoperative phases of heart surgery, as well as some personal observations of one of the authors, are described.
