Laxmi Kokatnur, Mohan Rudrappa
The diaphragm is the primary muscle of respiration, and its weakness can lead to respiratory failure. Diaphragmatic palsy can be caused by various causes. Injury to the phrenic nerve during thoracic surgeries is the most common cause for diaphragmatic palsy. Depending on the cause, the symptoms of diaphragmatic palsies vary from completely asymptomatic to disabling dyspnea requiring mechanical ventilation. On pulmonary function tests, there will be a decrease in the maximum respiratory muscle power. Spirometry shows reduced lung functions and a significant drop of lung function in supine position is typical of diaphragmatic palsy...

Computed tomography (CT)-guided lung biopsy is a well-established diagnostic method for pulmonary lesions. However, the use of this technique often results in pneumothorax development. The aim of the present study was to evaluate the association between biopsy needle angle and pneumothorax development associated with computed tomography-guided lung biopsy. We retrospectively analyzed the results of CT-guided lung biopsies for 325 cases to investigate physical risk factors for pneumothorax development. Biopsy needle angle and patient positioning were included in the analysis...

Objective: To explore the protective effect of electrical stimulation of phrenic nerve on diaphragmatic function during mechanical ventilation. Methods: Forty healthy adult SD rats were randomly divided into 5 groups: blank control group (BC), spontaneous breathing group (SB), electrical stimulation group (ES), mechanical ventilation group (MV), and electrical stimulation and mechanical ventilation group (MS). The rats in each group were treated for 18 h except for the BC group. After treatment, the diaphragm muscle tissue was obtained and the diaphragm contractility including peak-to-peak value(Vpp) and maximum rate of contraction(+ dT/dt max) were measured...

Context • Global morbidity from chronic obstructive pulmonary disease (COPD) is high worldwide. Diaphragm pacing (DP) can maintain the natural, negative pressure breathing of COPD patients with diaphragmatic muscle dysfunction. The YiqiDitanTongfu (YDTF) decoction has been used clinically with COPD patients to help them to wean from mechanical ventilation, with their ventilation functions being improved and the success rate of weaning being largely increased. Objective • The study intended to investigate the combined therapeutic effects of external DP and the YDTF decoction for COPD patients who have had difficulty weaning from mechanical ventilation...

Thoracic load carriage (LC) exercise impairs exercise performance compared to unloaded exercise, partially due to impaired respiratory mechanics. We investigated the effects of LC on exercise and diaphragmatic fatigue in a constant-load exercise task; and whether inspiratory muscle training (IMT) improved exercise capacity and diaphragmatic fatigue with LC. Twelve recreationally active males completed three separate running trials to exhaustion (Tlim ) at a fixed speed eliciting 70% of their V˙O2max . The first two trials were completed either unloaded (UL) or while carrying a 10 kg backpack (LC)...

Non-specific low back pain (NS-LBP) is known to cause respiratory dysfunction. In this study, we investigated alterations in breathing, respiratory strength and endurance, core stability, diaphragm mobility, and chest expansion among patients with NS-LBP and healthy individuals. The specific aim of the study was to correlate between respiratory function and other variables among NS-LBP patients. Thirty four patients with NS-LBP were matched with 34 healthy participants before undergoing total faulty breathing scale, spirometer, respiratory pressure meter, chest expansion, ultrasound, and pressure biofeedback measurements...

Individuals who suffer from trauma-related symptoms are a unique population that could benefit from the mind-body practice of yoga-or have their symptoms reactivated by it, depending on the type of yoga. Trauma-informed yoga (TIY), that is, yoga adapted to the unique needs of individuals working to overcome trauma, may ameliorate symptoms by creating a safe, tailored practice for students to learn how to respond, rather than react, to symptoms and circumstances. Yoga not thus adapted, on the other hand, may increase reactivity and activate symptoms such as hyperarousal or dissociation...

Diaphragm ultrasound (DUS) has been used to identify diaphragm dysfunction. However, its correlations with respiratory strength and lung function are unclear, even in healthy patients. A total of 64 healthy patients (30 males) had lung function and inspiratory strength (maximal inspiratory pressure and sniff nasal inspiratory pressure) measured. Gastric and oesophageal pressures were measured in a subgroup (n = 40). DUS was characterized by mobility (quiet breathing [QB] and deep breathing [DB]) and thickness (at functional residual capacity [ThFRC] and total lung capacity [ThTLC])...

Hemidiaphragmatic paralysis is usually caused by surgery, malignancy or trauma and rarely by viral infections. Herpes zoster (shingles) results in varied neurological complications, but peripheral motor involvement or diaphragmatic paralysis is rare. We report the case of an 87-year-old male who presented with worsening breathlessness soon after an episode of shingles, affecting his right neck and upper chest. He had no alarm symptoms, history of trauma or malignancy. Skin lesions resolved after a few weeks, but his breathing did not improve...

The transplantation of Olfactory Ecto-Mesenchymal Stem Cells (OEMSCs) could be a helpful therapeutic strategy for spinal cord repair. Using an acute rat model of high cervical contusion that provokes a persistent hemi-diaphragmatic and foreleg paralysis, we evaluated the therapeutic effect of a delayed syngeneic transplantation (two days post-contusion) of OEMSCs within the injured spinal cord. Respiratory function was assessed using diaphragmatic electromyography and neuro-electrophysiological recordings of phrenic nerves (innervating the diaphragm)...

There is evidence suggesting diaphragmatic fatigue (DF) occurs relatively early during high-intensity exercise; however, studies investigating the temporal characteristics of exercise-induced DF are limited by incongruent methodology. Eight healthy adult males (25 {plus minus} 5 years) performed a maximal incremental exercise test on a cycle ergometer on Day 1. A constant load time-to-exhaustion (TTE) exercise test was conducted on Day 2 at 60% delta between the calculated gas exchange threshold and peak work rate...

INTRODUCTION: The diaphragmatic response to increased mechanical load following withdrawal of mechanical ventilation (MV) is critical in determining the outcome of extubation. Using ultrasonography, we aimed to evaluate the performance of excursion-time (E-T) index- a product of diaphragm excursion and inspiratory time, to predict the outcome of extubation. METHODS: Right hemidiaphragm excursion, inspiratory time (Ti) and E-T index were measured using ultrasonography during MV: (1) On assist control mode (A/C) during consistent patient triggered ventilation (2) Following 30 minutes during a spontaneous breathing trial (SBT) (3) Between 4-24 hours following extubation...

Our understanding of the mechanisms of dyspnoea in fibrotic interstitial lung disease (ILD) is incomplete. The aims of this study were two-fold: 1) to determine whether dyspnoea intensity is better predicted by neural respiratory drive (NRD) or neuromechanical uncoupling (NMU) of the respiratory system in fibrotic ILD, and 2) to examine the effect of breathing 60% oxygen on NRD, NMU and dyspnoea ratings.Fourteen patients with fibrotic ILD were included. Visit 1 comprised a familiarisation incremental cycle exercise test, Visit 2 comprised a normoxic incremental cycling test to address Aim 1, and Visits 3 and 4 consisted of constant-load cycling while breathing room air or 60% oxygen to address Aim 2...

PURPOSE: Accurate reconstruction of myocardial T1 maps from a series of T1 -weighted images consists of cardiac motions induced from breathing and diaphragmatic drifts. We propose and evaluate a new framework based on active shape models to correct for motion in myocardial T1 maps. METHODS: Multiple appearance models were built at different inversion time intervals to model the blood-myocardium contrast and brightness changes during the longitudinal relaxation. Myocardial inner and outer borders were automatically segmented using the built models, and the extracted contours were used to register the T1 -weighted images...

Hepatic hydrothorax (HH) is a pleural effusion that develops in a patient with cirrhosis and portal hypertension in the absence of cardiopulmonary disease. Although the development of HH remains incompletely understood, the most acceptable explanation is that the pleural effusion is a result of a direct passage of ascitic fluid into the pleural cavity through a defect in the diaphragm due to the raised abdominal pressure and the negative pressure within the pleural space. Patients with HH can be asymptomatic or present with pulmonary symptoms such as shortness of breath, cough, hypoxemia, or respiratory failure associated with large pleural effusions...

Moo In Park
Rumination syndrome is one of the functional gastroduodenal disorders. Effortless and repetitive regurgitation of recently ingested food from the stomach to the oral cavity followed by rechewing and reswallowing or spitting are the characteristic clinical features. This disorder is believed to be uncommon, but many patients with this disorder are overlooked by their physicians. Rumination might be caused by a reversal of the gastric contents through the esophagogastric junction, which is initiated by an increase in intragastric pressure...

The electrical activity of the diaphragm (EAdi) shows global diaphragmatic activation and power output from the central nervous system. We measured the EAdi as an indicator of breathing workload in a 40-year-old man suffering from severe acute respiratory distress syndrome (ARDS) secondary to influenza pneumonia in the process of weaning from extracorporeal membrane oxygenation (ECMO). Turning off the sweep gas flow immediately led to EAdi elevation, followed by hypoxia. The patient was successfully weaned from ECMO by reference to EAdi...
