RESUMO

BACKGROUND: Endoscopic valve therapy aims at lung volume reduction that is associated with improved lung function, exercise tolerance and quality of life in emphysema patients. The size of intrabronchial valves of the Spiration® Valve System (SVS) selected to achieve lobar occlusion may have an influence on treatment outcomes. METHODS: 49 severe emphysema patients (M/F: 24/25, age: 64 ± 7 years), with complete interlobar fissures on the side intended to be treated, underwent treatment with at least one 9-mm intrabronchial valve implantation at 3 centers and were followed up at 30, 90 and 180 days after intervention. Changes in pulmonary function tests (PFT), 6-min walk test (6MWT), modified Medical Research Council (mMRC) dyspnea scale and chronic obstructive pulmonary disease assessment test scores as well as possible complications were recorded. RESULTS: Forced expiratory volume in 1 s (FEV1) improved significantly over the 6-month period of the study, and the proportion of patients achieving a minimal clinically important difference (MCID) for FEV1 was 46.4% at 6 months. Regarding the remaining PFT values, the changes were not statistically significant at 6 months, but when looking at the MCIDs, 44.4% of the patients achieved the MCID decrease for residual volume. The 6MWT distance also improved statistically significantly, and an MCID increase of ≥26 m was reached by 41.7% of the patients. Furthermore, there was a statistically significant improvement in the mMRC score. The incidence of pneumothoraxes requiring drainage was 26.5% while a valve dislocation rate of 24% was observed but only in the lower lobes. CONCLUSIONS: Endoscopic lung volume reduction with the 9-mm SVS valves was associated with statistically significant but modest improvement of FEV1, mMRC and 6MWT up to 6 months after intervention. These results were accompanied by an anticipated and acceptable risk profile. The relative increased incidence of device dislocation observed needs to be further elucidated.

RESUMO

PURPOSE: ICU acquired Weakness (ICUaW) is a common complication of critical illness. The aim of our study was the assessment of quality of life (QoL) and functional ability of patients with ICUaW, 6 months post hospital discharge. MATERIAL AND METHODS: Eight hundred seventy eight consecutive patients who had been discharged from the ICU were evaluated and 128 of them, 36 with ICUaW, were eligible for the study. Muscle strength was evaluated with MRC and Hand grip dynamometry. The Functional Independence Measure (FIM) was used to evaluate the functional ability while QoL was assessed with the Nottingham Health Profile and with the SF-36 questionnaire. RESULTS: Patients with ICUaW continued to have low MRC at hospital discharge, [53(49-56) vs. 59(58-60), p < 0.05]. Patients who developed ICUaW had lower Hand grip dynamometry at ICU, hospital discharge and 6 months after (p < 0.05). Patients with ICUaW have significantly lower FIM score at hospital discharge, 3 and 6 months post hospital discharge (p < 0.05) and persistently lower QoL at 3 and 6 months post hospital discharge(p < 0.05). CONCLUSIONS: ICUaW is associated with persistent deficiencies in functional ability and Qol leading to a prolonged period of recovery. Further research is needed in the field of prevention and targeted rehabilitation of functionality in this patient group.

RESUMO

BACKGROUND: Valve implantation provides a reversible effective therapy in a selected group of emphysema patients. Knowing predictors for successful therapy, the rate of treatment failure has decreased. Some patients, however, do not benefit, so that the valves may have to be removed. OBJECTIVES: To assess implant-related events, complications during valve removal, and clinical outcome after endoscopic procedure. METHODS: The data of 76 consecutive emphysema patients who underwent valve removal > 6 months since implantation were collected. RESULTS: Seventy-six patients (mean age 62 years, 54% male) underwent removal of all valves after a mean time of 624 days (193-3,043 days) since implantation. Granulation tissue was observed in 39.5% (30/76) and significant secretion in 34.2% (26/76). In 5.3% (4/76), valve removal was complicated requiring another bronchoscopy in 2 of them. In 5.3% (4/76) of the patients, one valve could not be removed and remained in situ. Bleeding requiring intervention occurred in 3.9% (3/76) during valve removal. Following bronchoscopy, there was a need for antibiotics in 34.2% (26/76), glucocorticosteroids in 1.3% (1/76), and both in 6.6% (5/76) due to productive cough or chronic obstructive pulmonary disease (COPD) exacerbation. Due to respiratory failure, invasive ventilation or noninvasive ventilation was necessary in 2.6% (2/76) and 6.6% (5/76), respectively, following procedure. No statistical significant change in lung function was observed following valve removal. CONCLUSIONS: Valve removal after > 6 months since implantation is feasible and associated with an acceptable safety profile. However, close monitoring of these patients with limited pulmonary reserve is recommended with particular attention to COPD exacerbations and respiratory failure.

RESUMO

PURPOSE: Intensive Care Unit (ICU) survivors experience muscle weakness leading to restrictions in functional ability. Neuromuscular electrical stimulation (NMES) has been an alternative to exercise in critically ill patients. The aim of our study was to investigate its effects along with individualized rehabilitation on muscle strength of ICU survivors. MATERIAL AND METHODS: Following ICU discharge, 128 patients (age: 53±16years) were randomly assigned to daily NMES sessions and individualized rehabilitation (NMES group) or to control group. Muscle strength was assessed by the Medical Research Council (MRC) score and hand grip at hospital discharge. Secondary outcomes were functional ability and hospital length of stay. RESULTS: MRC, handgrip, functional status and hospital length of stay did not differ at hospital discharge between groups (p>0.05). ΔMRC% one and two weeks after ICU discharge tended to be higher in NMES group, while it was significant higher in NMES group of patients with ICU-acquired weakness at two weeks (p=0.05). CONCLUSIONS: NMES and personalized physiotherapy in ICU survivors did not result in greater improvement of muscle strength and functional status at hospital discharge. However, in patients with ICU-aw NMES may be effective. The potential benefits of rehabilitation strategies should be explored in larger number of patients in future studies.

RESUMO

Previous studies on the health consequences of the crisis in Greece investigated short-term impacts on selected outcomes. This study examined the impact of the crisis on a key set of health indicators with longer follow up than previous studies. We conducted interrupted time series (ITS) analysis to compare trends in standardised mortality by cause before and during the crisis. We examined changes in fruit and vegetable consumption, smoking, physical activity, obesity, out-of-pocket payments and unmet needs for healthcare using national household data from the "Hellas Health" surveys. Standardised mortality rates for suicides (p < 0.001) and infant mortality (p = 0.003) increased during the crisis compared to pre-existing trends, while mortality from respiratory diseases (p = 0.053) and transport accidents (p = 0.067) decreased. The prevalence of smoking (42.6% to 36.5%; RR = 0.86) and sedentary lifestyle (43.4% to 29.0%; RR = 0.69) declined. The prevalence of unmet need for healthcare significantly increased from 10.0% to 21.9% (RR = 2.10) and the proportion of people paying out-of-pocket for healthcare from 34.4% to 58.7% (RR = 1.69) between 2010 and 2015. The impact of the economic crisis in Greece on health was more nuanced than previous reports suggest. Effective strategies to mitigate the adverse health impacts of economic crises need to be better understood and implemented.

RESUMO

BACKGROUND: Lung volume reduction coil (LVRC) treatment is established in daily endoscopic lung volume reduction routine. The aim of this study was to evaluate the safety and efficacy of LVRC treatment. PATIENTS AND METHODS: This was a retrospective analysis of 86 patients (male/female: 40/46, mean age: 64±7 years) with severe COPD and bilateral incomplete fissures. A total of 10 coils were unilaterally implanted in a single lobe, and 28 out of 86 patients were treated bilaterally. At 90-, 180-, and 365-day follow-up, changes in pulmonary function test (PFT), 6-minute walk test (6MWT) and modified Medical Research Council (mMRC) dyspnea scale, as well as possible complications, were recorded. RESULTS: At 90 days, the forced expiratory volume in 1 second did improve (P<0.001), but the improvement was not sustained at the 180- and 365-day follow-up (baseline: 0.71±0.21 vs 0.77±0.23 vs 0.73±0.22 vs 0.70±0.18 L). Both vital capacity and residual volume improved significantly (P<0.001) at the 90- and 180-day follow-up, but the improvement was lost after 365 days. Total lung capacity decreased at the 90-day follow-up but returned to baseline values at the 180- and 365-day follow-up. 6MWT (P=0.01) and mMRC (P=0.007) also improved at 90 and 180 days (Δ6MWT of 31±54 and 20±60 m, respectively), but the improvement was also lost at the 365-day follow-up. No significant further improvement was evident at any point in the follow-up after the second procedure. A total of 4 out of 86 patients passed away due to complications. Significant complications in the first 3 months and then at 12 months included the following: severe hemoptysis in 4 (3.5%) and 4 (3.5%) patients, pneumonia requiring hospitalization in 32 (28.1%) and 9 (7.9%) patients and pneumothorax in 7 (6.1%) and 2 (1.7%) patients, respectively. Milder adverse events included self-limited hemoptysis, pneumonias, or COPD exacerbations treated orally. CONCLUSION: LVRC improved PFT, 6MWT and mMRC initially, but the improvement was lost after 365 days. Furthermore, we observed 4 deaths and significant severe complications, which need to be further elucidated.

RESUMO

OBJECTIVE: This study assessed changes in levels of ever use, perceptions of harm from e-cigarettes and sociodemographic correlates of use among European Union (EU) adults during 2012-2014, as well as determinants of current use in 2014. METHODS: We analysed data from the 2012 (n=26 751) and 2014 (n=26 792) waves of the adult Special Eurobarometer for Tobacco survey. Point prevalence of current and ever use was calculated and logistic regression assessed correlates of current use and changes in ever use, and perception of harm. Correlates examined included age, gender, tobacco smoking, education, area of residence, difficulties in paying bills and reasons for trying an e-cigarette. RESULTS: The prevalence of ever use of e-cigarettes increased from 7.2% in 2012 to 11.6% in 2014 (adjusted OR (aOR)=1.91). EU-wide coefficient of variation in ever e-cigarette use was 42.1% in 2012 and 33.4% in 2014. The perception that e-cigarettes are harmful increased from 27.1% in 2012 to 51.6% in 2014 (aOR=2.99), but there were major differences in prevalence and trends between member states. Among those who reported that they had ever tried an e-cigarette in the 2014 survey, 15.3% defined themselves as current users. Those who tried an e-cigarette to quit smoking were more likely to be current users (aOR=2.82). CONCLUSIONS: Ever use of e-cigarettes increased during 2012-2014. People who started using e-cigarettes to quit smoking tobacco were more likely to be current users, but the trends vary by country. These findings underscore the need for more research into factors influencing e-cigarette use and its potential benefits and harms.

RESUMO

BACKGROUND: Ventilator-associated pneumonia (VAP), one of the most common hospital-acquired infections, has a high mortality rate. OBJECTIVES: To evaluate the incidence of VAP in a multidisciplinary intensive care unit and to examine the effects of the implementation of ventilator bundles and staff education on its incidence. METHODS: A 24-month-long before/after study was conducted, divided into baseline, intervention, and postintervention periods. VAP incidence and rate, the microbiological profile, duration of mechanical ventilation, and length of stay in the intensive care unit were recorded and compared between the periods. RESULTS: Of 1097 patients evaluated, 362 met the inclusion criteria. The baseline VAP rate was 21.6 per 1000 ventilator days. During the postintervention period, it decreased to 11.6 per 1000 ventilator days (P = .01). Length of stay in the intensive care unit decreased from 36 to 27 days (P = .04), and duration of mechanical ventilation decreased from 26 to 21 days (P = .06). CONCLUSIONS: VAP incidence was high in a general intensive care unit in a Greek hospital. However, implementation of a ventilator bundle and staff education has decreased both VAP incidence and length of stay in the unit.

RESUMO

BACKGROUND: Endoscopic valve implantation is an effective treatment for patients with advanced emphysema. Despite the minimally invasive procedure, valve placement is associated with risks, the most common of which is pneumothorax. This study was designed to identify predictors of pneumothorax following endoscopic valve implantation. METHODS: Preinterventional clinical measures (vital capacity, forced expiratory volume in 1 second, residual volume, total lung capacity, 6-minute walk test), qualitative computed tomography (CT) parameters (fissure integrity, blebs/bulla, subpleural nodules, pleural adhesions, partial atelectasis, fibrotic bands, emphysema type) and quantitative CT parameters (volume and low attenuation volume of the target lobe and the ipsilateral untreated lobe, target air trapping, ipsilateral lobe volume/hemithorax volume, collapsibility of the target lobe and the ipsilateral untreated lobe) were retrospectively evaluated in patients who underwent endoscopic valve placement (n=129). Regression analysis was performed to compare those who developed pneumothorax following valve therapy (n=46) with those who developed target lobe volume reduction without pneumothorax (n=83). FINDING: Low attenuation volume% of ipsilateral untreated lobe (odds ratio [OR] =1.08, P=0.001), ipsilateral untreated lobe volume/hemithorax volume (OR =0.93, P=0.017), emphysema type (OR =0.26, P=0.018), pleural adhesions (OR =0.33, P=0.012) and residual volume (OR =1.58, P=0.012) were found to be significant predictors of pneumothorax. Fissure integrity (OR =1.16, P=0.075) and 6-minute walk test (OR =1.05, P=0.077) were also indicative of pneumothorax. The model including the aforementioned parameters predicted whether a patient would experience a pneumothorax 84% of the time (area under the curve =0.84). INTERPRETATION: Clinical and CT parameters provide a promising tool to effectively identify patients at high risk of pneumothorax following endoscopic valve therapy.

RESUMO

BACKGROUND AND OBJECTIVE: The aim of endoscopic valve therapy in patients with emphysema is complete lobar atelectasis of the most emphysematous lobe. However, even after the radiological advent of atelectasis, great variability in clinical outcomes can be observed. METHODS: The baseline clinical measures (vital capacity (VC), forced expiratory flow in 1 s (FEV1 ), residual volume (RV) and 6-min walk test (6-MWT)) and computed tomography variables (low attenuation volume (LAV) of the target lobe, LAV% of the target and the ipsilateral untreated lobe and LAV of the target lobe to LAV of the target lung and to LAV of the total lung) of 77 patients with complete atelectasis following valve therapy were retrospectively examined to determine their impact on patient´s outcome (changes in VC, FEV1 , RV and 6-MWT from baseline to the time of atelectasis). RESULTS: Low attenuation volume of the target lobe to LAV of the target lung predicts a significant FEV1 improvement in patients with complete lobar atelectasis following valve therapy. A 10% difference in that computed tomography predictor was associated with a 82-mL improvement in FEV1 (P = 0.006). Lower 6-MWT scores, low VC and high RV at baseline were significantly associated with greater improvement in the respective parameter (all P < 0.001). CONCLUSION: Low attenuation volume of the target lobe to LAV of the target lung and baseline clinical measures seem to significantly predict clinical outcomes in patients with complete lobar atelectasis following valve treatment.

RESUMO

BACKGROUND: Although interventional management of malignant central airway obstruction (mCAO) is well established, its impact on survival and quality of life (QoL) has not been extensively studied. AIM: We prospectively assessed survival, QoL and dyspnea (using validated EORTC questionnaire) in patients with mCAO 1 day before interventional bronchoscopy, 1 week after and every following month, in comparison to patients who declined this approach. Material/Patients/Methods: 36 patients underwent extensive interventional bronchoscopic management as indicated, whereas 12 declined. All patients received full chemotherapy and radiotherapy as indicated. Patients of the 2 groups were matched for age, comorbidities, type of malignancy and level of obstruction. Follow up time was 8.0±8.7 (range 1-38) months. RESULTS: Mean survival for intervention and control group was 10±9 and 4±3 months respectively (p=0.04). QoL improved significantly in intervention group patients up to the 6(th) month (p<0.05) not deteriorating for those surviving up to 12 months. Dyspnea decreased in patients of the intervention group 1 month post procedure remaining reduced for survivors over the 12th month. Patients of the control group had worse QoL and dyspnea in all time points. CONCLUSIONS: Interventional management of patients with mCAO, may achieve prolonged survival with sustained significant improvement of QoL and dyspnea.

RESUMO

BACKGROUND: Endothelial progenitor cells (EPCs) have been suggested to constitute a restoration index of the disturbed endothelium in ICU patients. Neuromuscular electric stimulation (NMES) is increasingly employed in ICU to prevent comorbidities such as ICU-acquired weakness, which is related to endothelial dysfunction. The role of NMES to mobilize EPCs has not been investigated yet. The purpose of this study was to explore the NMES-induced effects on mobilization of EPCs in septic ICU patients. METHODS: Thirty-two septic mechanically ventilated patients (mean ± SD, age 58 ± 14 years) were randomized to one of the two 30-min NMES protocols of different characteristics: a high-frequency (75 Hz, 6 s on-21 s off) or a medium-frequency (45 Hz, 5 s on-12 s off) protocol both applied at maximally tolerated intensity. Blood was sampled before and immediately after the NMES sessions. Different EPCs subpopulations were quantified by cytometry markers CD34(+)/CD133(+)/CD45(-), CD34(+)/CD133(+)/CD45(-)/VEGFR2 (+) and CD34(+)/CD45(-)/VEGFR2 (+). RESULTS: Overall, CD34(+)/CD133(+)/CD45(-) EPCs increased from 13.5 ± 10.2 to 20.8 ± 16.9 and CD34(+)/CD133(+)/CD45(-)/VEGFR2 (+) EPCs from 3.8 ± 5.2 to 6.4 ± 8.5 cells/10(6) enucleated cells (mean ± SD, p < 0.05). CD34(+)/CD45(-)/VEGFR2 (+) EPCs also increased from 16.5 ± 14.5 to 23.8 ± 19.2 cells/10(6) enucleated cells (mean ± SD, p < 0.05). EPCs mobilization was not affected by NMES protocol and sepsis severity (p > 0.05), while it was related to corticosteroids administration (p < 0.05). CONCLUSIONS: NMES acutely mobilized endothelial progenitor cells, measures of the endothelial restoration potential, in septic ICU patients.

RESUMO

BACKGROUND: Sedentary lifestyle is associated with more than three million deaths annually. Data from the 2013 Eurobarometer survey were analyzed to assess levels of physical activity across the European Union (EU) and to explore factors associated with adequate and high physical activity. METHODS: A representative sample of n=19,978 individuals aged 18-64 years from the 28 EU countries (sub-sample of the Eurobarometer survey, wave 80.2) was analyzed. Frequency and average duration of walking, moderate and vigorous physical activity was assessed with a self-reported questionnaire. Participants were then classified as physically inactive or adequately/highly active, based on the World Health Organization's (WHO) recommendations. The total amount of MET-minutes (MET-min) per week was also calculated for each respondent. RESULTS: The proportion of physically inactive individuals was 28.6%, (12.4% in Sweden to 53.7% in Cyprus), while 59.1% of the respondents (37.9% in Portugal and Cyprus to 72.2% in Sweden) were classified as highly active. The mean total weekly physical activity was 2151 MET-min (95%CI: 2095-2206), of which 891 MET-min (95%CI: 858-924) were contributed by vigorous exercise, 559 MET-min (95%CI: 540-578) by moderate exercise (excluding walking) and 690 MET-min (95%CI: 673-706) by walking. Male gender, younger age, residence in rural areas and Northern Europe, higher education level and ability to pay bills were independently associated with higher physical activity. CONCLUSION: One fourth of the EU population did not meet the WHO's recommendations for physical activity, with wide inequalities between and within countries. Wide-reaching environmental approaches are required to promote physical activity and address these inequalities.

RESUMO

BACKGROUND: One of the most common forms of pulmonary hypertension (PH) is that associated with chronic obstructive pulmonary disease (COPD). So far, patients with severe emphysema and established PH have been excluded from endoscopic lung volume reduction (ELVR) therapy due to the risk of right heart decompensation. OBJECTIVE: The aim of this pilot study was to evaluate the feasibility and efficacy of ELVR using one-way endobronchial valves (EBV) in this specific group of patients. METHODS: We prospectively included 6 patients with COPD, severe heterogeneous emphysema, and established PH who underwent right heart catheterization and clinical assessments before and 90 days after ELVR with unilateral EBV placement. RESULTS: This study was not powered to measure any statistical differences in endpoints. Ninety days after ELVR, the symptoms, lung function, and hemodynamics improved in 5 out of 6 patients (1 patient normalized and 1 slightly worsened). The mean hemodynamics improved from baseline to 90 days after ELVR as follows: mean pulmonary artery pressure, -2.5 ± 3.5 mm Hg; pulmonary arterial wedge pressure, -4.3 ± 8.3 mm Hg; cardiac index, +0.3 ± 0.6 l/min/m(2), and 6-min walk distance, +59 ± 99 m. ELVR was performed without PH-related complications in all patients. CONCLUSION: To our knowledge, this is the first prospective, single-center pilot study to evaluate the feasibility and efficacy of ELVR in patients with established PH. ELVR was feasible and resulted in an improvement of clinical and hemodynamic parameters in 5 out of 6 patients. These results have to be further confirmed in larger-scale controlled studies.

RESUMO

BACKGROUND: Vasopressin administration has been tested in cardiac arrest. However it has not been tested when cardiac arrest occurs in certain circumstances, as in sepsis, where it may have a major role. The aim of the study was to investigate survival after cardiac arrest in a septic porcine model compared with healthy animals and to explore the effectiveness of adding vasopressin vs epinephrine alone administration. METHODS: Thirty five healthy piglets of both genders were studied. The piglets were randomly assigned into three groups: group A (n = 8), group B (n = 14), group C (n = 13). Animals of groups B and C were given endotoxin to mimic a septic state before arrest. We applied the same resuscitation protocol to all pigs but we replaced the first dose of epinephrine with vasopressin in pigs of group C. Following surgical preparation and 30 min resting period, baseline measurements were recorded. In order to assess tissue oxygenation, we implemented Near Infrared Spectroscopy (NIRS) with the vascular occlusion technique (VOT) in thirteen lipopolysaccharide (LPS)-treated animals, occluding abdominal aorta and inferior vena cava. Afterwards, LPS (100 µg/kg) was infused in a 30 min period to animals of groups B and C and normal saline to group A. New NIRS measurements were obtained again. Subsequently, we provoked ventricular fibrillation (VF). After 3 min of untreated VF, open chest cardiopulmonary resuscitation (CPR) was performed manually. Primary end point was the restoration of spontaneous circulation (ROSC). RESULTS: The chance of ROSC for the groups A, B and C was 75%, 35.7%, and 30.7% respectively. A significant difference in ROSC was established between septic (group B + C) and non septic piglets (group A) (P = 0.046). Vasopressin administration had no effect in outcome. LPS administration decreased oxygen consumption rate, as assessed by NIRS, in peripheral tissues (22.6 ± 7.2. vs 18.5 ± 7.2, P = 0.07). CONCLUSION: Septic piglets have fewer chances to survive after cardiac arrest. No difference in outcome was observed when the first dose of epinephrine was replaced with vasopressin to treat cardiac arrest in the LPS-treated animals.

RESUMO

OBJECTIVE: To investigate whether having multiple risk factors for cardiovascular disease is associated with having had cholesterol and blood pressure measurements in the past year. METHODS: Cross-sectional data from the 2009 Eurobarometer survey (wave 72.3), were analysed. Self-reported data on smoking, fruit consumption, alcohol consumption and physical activity were collected from 15,287 individuals aged between 40 and 75 years from 27 European countries. RESULTS: Having had a cholesterol test was inversely associated with smoking (OR=0.85; 95% CI:0.74-0.96), high alcohol (OR=0.81; 95% CI: 0.66-0.99) and low fruit consumption (OR=0.83; 95% CI: 0.73-0.93), but not with sedentary lifestyle. Having had a blood pressure test was also inversely associated with smoking (OR=0.84; 95% CI: 0.73-0.97), high alcohol (OR=0.74; 95% CI: 0.60-0.92) and low fruit consumption (OR=0.73; 95% CI: 0.64-0.84). The more risk factors reported by respondents, the less likely they were to have had a preventive test in the past year. Individuals with all four risk factors were less likely to have had their cholesterol (OR=0.42; 95% CI: 0.26-0.68) and blood pressure (OR=0.45; 95% CI: 0.27-0.75) measured compared to individuals with no risk factors. CONCLUSIONS: Screening strategies in Europe need to be revised, as Europeans at the highest risk for cardiovascular diseases were the least likely to have received cholesterol or blood pressure tests.

RESUMO

BACKGROUND: Treatment with lung volume reduction coils (LVRC) may be effective in patients with severe heterogeneous emphysema and incomplete fissures. OBJECTIVE: We hypothesized that LVRC placement improves pulmonary function, exercise tolerance and quality of life in these patients. METHODS: Twenty-six patients with chronic obstructive pulmonary disease (COPD), 13 males and 13 females, aged 66 ± 8 years with heterogeneous emphysema and incomplete fissures were included in this retrospective analysis. The coils were implanted unilaterally in the upper or lower lobe. Patients were followed up at 30, 90 and 180 days after treatment and changes in pulmonary function test and 6-minute-walk-test (6MWT) values as well as scores for the modified Medical Research Council (mMRC) dyspnea scale and the St. George's Respiratory Questionnaire (SGRQ) were recorded. RESULTS: FEV1 improved significantly at 90 days and tended to decrease at the 180-day follow-up (0.67 ± 0.17 vs. 0.78 ± 0.25 vs. 0.73 ± 0.21 liters, respectively, p < 0.001). The 6MWT score had improved significantly at 90 days and had tended to decrease at the 180-day follow-up (216 ± 107 vs. 262 ± 97 vs. 262 ± 112 m, respectively, p = 0.001). SGRQ was significantly improved at 90 days. Multivariate analysis showed that worse 6MWT performance at baseline was independently associated with a greater improvement in 6MWT at the 90-day follow-up. The total complication rate was 54% (n = 14) and included light hemorrhage in 6 patients, COPD exacerbation in 6, pneumothorax in 1 and both COPD exacerbation and pneumothorax in 1 patient. CONCLUSIONS: This is the first study to show that LVRC in patients with heterogeneous emphysema and incomplete fissures improves exercise capacity, quality of life and lung function up to 90 days after the intervention. Further studies are needed to assess the long-term effects of LVRC in these patients.
