Hedonic Responses to Meal Ingestion in Patients With Functional Dyspepsia and Postprandial Symptoms.

Introduction: It is not clear whether patients with postprandial symptoms enjoy the meal.

Methods: Prospective trial in patients with postprandial distress syndrome and healthy controls, comparing their responses with stepwise ingestion of a comfort meal.

Results: Healthy individuals (N = 18) enjoyed the meal and experienced digestive well-being.

Thoracoabdominal Wall Motion-Guided Biofeedback Treatment of Abdominal Distention: A Randomized Placebo-Controlled Trial.

Background & Aims: Abdominal distention results from abdominophrenic dyssynergia (ie, diaphragmatic contraction and abdominal wall relaxation) in patients with disorders of gut-brain interaction. This study aimed to validate a simple biofeedback procedure, guided by abdominothoracic wall motion, for treating abdominal distention.

Methods: In this randomized, parallel, placebo-controlled trial, 42 consecutive patients (36 women and 6 men; ages 17-64 years) with meal-triggered visible abdominal distention were recruited.

Pulmonary vascular pressure respiratory swings in COPD and ILD candidates for lung transplantation: Large but different.

We analyzed the effect of respiratory swings on interpreting intravascular pulmonary vascular pressures (PVPs) in chronic obstructive pulmonary disease (COPD) and interstitial lung disease (ILD) candidates for lung transplantation (LTx) and the role of the alterations in pulmonary function tests on the dynamic respiratory variations. Twenty-eight consecutive patients were included. All patients underwent a complete hemodynamic study (right atrial, mean pulmonary arterial, and pulmonary arterial occlusion pressures [RAP, mPAP, and PAOP]-) and pulmonary function testing (force vital capacity [FVC], forced expiratory volume in the first second [FEV1], and residual volume [RV]).
