Correlation between Perceived Asthma Control and Thoraco-Abdominal Asynchrony in Primary Care Patients Diagnosed with Asthma.
Summary of "Correlation between Perceived Asthma Control and Thoraco-Abdominal Asynchrony in Primary Care Patients Diagnosed with Asthma."
Objective. Thoraco-abdominal asynchrony (TAA), the discordant movement of the abdomen and thorax, may impact upon health-related variables. Here, we investigated the extent to which TAA is associated with health-related variables, particularly perceived asthma control and quality of life. Methods. Ambulatory respiratory data from 43 patients diagnosed with asthma and 43 healthy age and sex-matched controls were recorded over 4 hours. Phase relation (Ph Rel Total), the percentage of time that the effects of rib cage (RC) and diaphragmatic movement result in opposite effects on intra-thoracic volume, quantified TAA. Subjects completed the Mini Asthma Quality of Life Questionnaire (AQLQ), Asthma Control Questionnaire (ACQ), Nijmegen questionnaire (NQ), Hospital Anxiety and Depression Scale (HADS), Spielberger State-Trait Anxiety Inventory (STAI), and General Health Perception (GHP) subscale of the short form 36 questionnaire'. Capnography profiling, breath-hold time (BHT), and standard spirometry were performed. Results. The time in asynchrony was significantly greater in the asthma than in the healthy control group (Ph Rel Total = 14% (interquartile range (IQR) 8.5-20.7%) versus 10.4% (IQR 7.1-14.5%), p = .012). In patients with asthma, Ph Rel Total was weakly associated with poorer ACQ scores (r = 0.33, p = .03), and in the healthy control group with GHP (r = 0.319, p = .037). Post-hoc exploratory analysis revealed a moderate relationship in the female asthma subgroup between Ph Rel Total and AQLQ (r = -0.56, p = .003). Conclusions. TAA may be associated with decreased perceived asthma control. In healthy individuals, asynchrony may be associated with low perception of general health. Further studies are required to investigate if the reduction of TAA improves these health-related variables.

Medical and Biotech [MESH] Definitions
Hernia, Abdominal
A protrusion of abdominal structures through the retaining ABDOMINAL WALL. It involves two parts: an opening in the abdominal wall, and a hernia sac consisting of PERITONEUM and abdominal contents. Abdominal hernias include groin hernia (HERNIA, FEMORAL; HERNIA, INGUINAL) and VENTRAL HERNIA.
Fibromatosis, Aggressive
A childhood counterpart of abdominal or extra-abdominal desmoid tumors, characterized by firm subcutaneous nodules that grow rapidly in any part of the body but do not metastasize. The adult form of abdominal fibromatosis is FIBROMATOSIS, ABDOMINAL. (Stedman, 25th ed)
Abdominal Fat
Fatty tissue in the region of the ABDOMEN. It includes the ABDOMINAL SUBCUTANEOUS FAT and the INTRA-ABDOMINAL FAT.
Abdominal Wound Closure Techniques
Methods to repair breaks in abdominal tissues caused by trauma or to close surgical incisions during abdominal surgery.
Peritonitis
INFLAMMATION of the PERITONEUM lining the ABDOMINAL CAVITY as the result of infectious, autoimmune, or chemical processes. Primary peritonitis is due to infection of the PERITONEAL CAVITY via hematogenous or lymphatic spread and without intra-abdominal source. Secondary peritonitis arises from the ABDOMINAL CAVITY itself through RUPTURE or ABSCESS of intra-abdominal organs.
