Original article: Quality of life after esophagectomy and endoscopic therapy for Barrett's esophagus with dysplasia

DISEASES OF THE ESOPHAGUS, Issue 6 2010
D. Schembre
SUMMARY Esophagectomy (EG) and endoscopic therapy (ET) can eradicate Barrett's esophagus with early neoplasia. Their relative effect on quality of life is unknown. The 36-item Short Form Health Survey (SF-36) and Gastrointestinal Quality of Life Index (GIQLI) questionnaires were sent to all patients who underwent either EG or ET at our institution over the last 9 years. Groups were stratified by age and American Society of Anesthesia (ASA) class. Surveys were sent to 77 patients and completed by 14 EG (50%) and by 28 ET patients (57%). The average time between treatment and survey was 4 years in the ET group and 5 years in the EG group. There were no significant differences in SF-36 scores between EG and ET patients except for superior physical functioning among EG patients 65 and older QOL scores among EG and ET groups were not significantly different than sex age-matched controls. GIQLI scores were similar between ET and EG patients of all ages (P= 0.60). GIQLI scores were higher among younger ET patients than young EG patients (P= 0.049). GIQLI scores also tended to be higher among ASA 1 and 2 ET patients than ASA 1 and 2 EG patients, but this did not reach statistical significance (P= 0.09). EG and ET for early Barrett's neoplasia appear to have similar impact on QOL 1 year or more after treatment compared with age-matched controls. Negative QOL impact appears to be greater for younger patients undergoing EG than for ET. [source]


An Evaluation of a Blind Rotational Technique for Selective Mainstem Intubation

ACADEMIC EMERGENCY MEDICINE, Issue 10 2004
Aaron E. Bair MD
Abstract Objectives: Although rare, massive hemoptysis and major bronchial disruptions are associated with high mortality. Selective ventilation of the uninvolved lung can increase the likelihood of survival. Specialized devices used for single lung ventilation are often not readily available and can be difficult to place in the emergency department. The authors evaluated a blind rotational technique for selective mainstem intubation using either a standard endotracheal tube (ET) or a directional-tip endotracheal tube (DTET). Methods: This was a prospective, randomized trial on 25 human cadavers. The desired side of mainstem intubation was determined by randomization. Each cadaver was used for four ET, four DTET, and four control intubations. In the ET group, the trachea was intubated. The tube was then rotated 90° in the direction of the desired placement and advanced until resistance was met. In the DTET group, the technique was identical, except the trigger was activated to flex the tip during advancement. In the control group, an ET was advanced in neutral alignment until resistance was met. A bronchoscopist blinded to the desired placement determined tube position. Comparison testing was performed using Pearson's chi-square test. Results: When attempting to intubate the left mainstem, use of the ET with the rotational technique was successful 72.3% of the time (95% confidence interval [95% CI] = 57% to 84%). Intubation of the left mainstem using the DTET was successful 68.5% of the time (95% CI = 54% to 81%; p = 0.67). Attempts to selectively intubate the right mainstem using the rotational technique were highly successful in both groups: 94% for the ET (95% CI = 84% to 99%) versus 97.8% for the DTET (95% CI = 89% to 100%). Among controls, the right mainstem was intubated 93% of the time (95% CI = 86% to 97%). Conclusions: In a cadaveric model, the left mainstem bronchus can be selectively intubated with moderate reliability using this rotational technique. Use of a DTET confers no significant advantage. The ability to generalize these findings to living subjects is unknown. [source]


Endurance Exercise Training in Older Patients with Heart Failure: Results from a Randomized, Controlled, Single-Blind Trial

Peter H. Brubaker PhD
OBJECTIVES: To test the hypothesis that exercise training (ET) improves exercise capacity and other clinical outcomes in older persons with heart failure with reduced ejection fraction (HfrEF). DESIGN: Randomized, controlled, single-blind trial. SETTING: Outpatient cardiac rehabilitation program. PARTICIPANTS: Fifty-nine patients aged 60 and older with HFrEF recruited from hospital records and referring physicians were randomly assigned to a 16-week supervised ET program (n=30) or an attention-control, nonexercise, usual care control group (n=29). INTERVENTION: Sixteen-week supervised ET program of endurance exercise (walking and stationary cycling) three times per week for 30 to 40 minutes at moderate intensity regulated according to heart rate and perceived exertion. MEASUREMENTS: Individuals blinded to group assignment assessed four domains pivotal to HFrEF pathophysiology: exercise performance, left ventricular (LV) function, neuroendocrine activation, and health-related quality of life (QOL). RESULTS: At follow-up, the ET group had significantly greater exercise time and workload than the control group, but there were no significant differences between the groups for the primary outcomes: peak exercise oxygen consumption (VO2 peak), ventilatory anaerobic threshold (VAT), 6-minute walk distance, QOL, LV volumes, EF, or diastolic filling. Other than serum aldosterone, there were no significant differences after ET in other neuroendocrine measurements. Despite a lack of a group "training" effect, a subset (26%) of individuals increased VO2 peak by 10% or more and improved other clinical variables as well. CONCLUSION: In older patients with HFrEF, ET failed to produce consistent benefits in any of the four pivotal domains of HF that were examined, although the heterogeneous response of older patients with HFrEF to ET requires further investigation to better determine which patients with HFrEF will respond favorably to ET.

A Randomized, Controlled Trial of Fall Prevention Programs and Quality of Life in Older Fallers

JOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 4 2007
Mau-Roung Lin PhD
OBJECTIVES: To compare the effects of three fall-prevention programs (education (ED), home safety assessment and modification (HSAM), and exercise training (ET)) on quality of life (QOL), functional balance and gait, activities of daily living (ADLs), fear of falling, and depression in adults aged 65 and older. DESIGN: A 4-month randomized trial. SETTING: Randomized, controlled trial. PARTICIPANTS: One hundred fifty participants who had experienced a recent fall. MEASUREMENTS: QOL was assessed according to the brief version of the World Health Organization Quality of Life instrument (WHOQOL-BREF), functional balance and gait according to functional reach and Tinetti balance and gait, ADLs according to the Older Americans Resources and Services questionnaire, fear of falling according to a visual analog scale, and depression level according to the Geriatric Depression Scale. RESULTS: The score changes for the ET group were 2.1 points greater on the physical domain (95% confidence interval (CI)=,1.2,5.3), 3.8 points greater on the psychological domain (95% CI=0.7,7.0), and for the WHOQOL-BREF, 3.4 points greater on the social domain (95% CI=0.7,6.1) and 3.2 points greater on the environmental domain (95% CI=0.6,5.7) than for the ED group. The score change for each domain of the WHOQOL-BREF for the HSAM group was greater than that for the ED group, although these results were not statistically significant. The ET group also had greater improvements in functional reach, Tinetti balance and gait, and fear of falling than the ED group. CONCLUSION: The QOL outcome supports the superiority of ET over the other two interventions in older people who have recently fallen. This finding also parallels those gathered from the functional measures. [source]


Emergence of Graphic Symbol Functioning and the Question of Domain Specificity: A Longitudinal Training Study

CHILD DEVELOPMENT, Issue 2 2002
Tara C. Callaghan
The impact of social scaffolding on the emergence of graphic symbol functioning was explored in a longitudinal training study. Links among graphic, language, and play domains in symbolic development were also investigated. The symbolic functioning of 16 children, who were 28 months at the outset of the study, was assessed in comprehension and production tasks across the three domains at monthly intervals from 28 to 36 months, and again at 42 months. Training was delivered in between monthly assessments during weekly visits. Half of the children received training, which consisted of the experimenter drawing common objects and highlighting the relation between pictures and their referents, for 16 consecutive weeks early in the study (early training, ET). The remaining half received a placebo version of training for these 16 weeks, followed by actual training for 4 weeks in the fifth month (late training, LT). After the first 4 months of training the ET group was found to have accelerated comprehension and production of graphic symbols relative to the LT group. After the fifth month, the LT group reached the same level of graphic symbol performance as the ET group. There were strong positive correlations found among graphic symbol functioning and language and play, and between play and language. These findings support the view that graphic symbolic development can be influenced by cultural scaffolding, that more extensive training is needed early rather than later in development, and that interrelationships exist among symbolic domains.
