RESUMO
Introduction: Prevalence and predisposing factors for the development of thoracic pain (TP) in patients with chronic interstitial lung disease (cILD) are largely unknown. Underestimation and insufficient therapy of pain can lead to worsened ventilatory function. Quantitative sensory testing is an established tool for characterization of chronic pain and its neuropathic components. We investigated frequency and intensity of TP in cILD patients and the potential association with lung function and quality of life. Materials and methods: We prospectively investigated patients with chronic interstitial lung disease to analyze risk factors for the development of thoracic pain and quantify thoracic pain through quantitative sensory testing. In addition, we studied the relationship between pain sensitivity and lung function impairment. Results: Seventy-eight patients with chronic interstitial lung disease and 36 healthy controls (HCs) were included. Thoracic pain occurred in 38 of 78 patients (49%), most frequently in 13 of 18 (72%, p = 0.02) patients with pulmonary sarcoidosis. The occurrence was mostly spontaneous and not related to thoracic surgical interventions (76%, p = 0.48). Patients with thoracic pain showed a significant impairment of mental well-being (p = 0.004). A higher sensitivity to pinprick stimulation during QST can be observed in patients with thoracic pain (p < 0.001). Steroid treatment was associated with lower sensitivity within thermal (p = 0.034 and p = 0.032) and pressure pain testing (p = 0.046). We observed a significant correlation between total lung capacity and thermal (p = 0.019 and p = 0.03) or pressure pain sensitivity (p = 0.006 and p = 0.024). Conclusion: This study was performed to investigate prevalence, risk factors and thoracic pain in patients with chronic interstitial lung disease. Thoracic pain mostly occurs spontaneous as a frequent symptom, and seems to be an underestimated symptom in patients with chronic interstitial lung disease, especially those with pulmonary sarcoidosis. Timely identification of thoracic pain may allow starting symptomatic treatment at early stage, before impairment in quality of life occurs.

RESUMO
BACKGROUND: Obstructive sleep apnea (OSA), nocturnal hypoxemia and excessive daytime sleepiness (EDS) are common comorbidities in people with cystic fibrosis (pwCF). Most of the data showing this originates from children and adolescents. The aim of this study was to collect data on sleep parameters, EDS and pulmonary function from a large cohort of adult pwCF. METHODS: Full overnight polysomnography (PSG) was performed. EDS was determined using the Epworth Sleepiness Scale (ESS). Demographic and clinical data (body mass index [BMI], pulmonary function, capillary blood gases) were collected. RESULTS: A total of 52 adult pwCF were included (mean age 30.7 ± 8.0 years, mean percent predicted forced expiratory volume in 1 s [ppFEV1] of 52.1 ± 14.8). Overall AHI was in the normal range (4.5 ± 4.0/h); 21/52 pwCF (40%) had an apnea-hypopnea index > 5/h. Nocturnal hypoxemia was found in 25% of participants and this was associated with ppFEV1 (p = 0.014), awake oxygen saturation (SpO2; p = 0.021) and awake partial pressure of oxygen (pO2; p = 0.003); there were no significant differences in age, lung function and BMI were found for pwCF with versus without OSA (all p > 0.05). Eight pwCF (15%) had an ESS score > 10 (indicating EDS). OSA was best predicted by awake pO2 (area under the curve [AUC] 0.66, p = 0.048), while nocturnal hypoxemia was best predicted by ppFEV1 (AUC 0.74, p = 0.009), awake pO2 (AUC 0.76, p = 0.006) and awake SpO2 (AUC 0.71; p = 0.025). CONCLUSION: OSA, nocturnal hypoxemia and EDS were common in adult pwCF, but no strong predictors were identified. Therefore, we suggest regular PSG and ESS scoring in adult pwCF, regardless of disease severity.

BACKGROUND: Sleep-disordered breathing (SDB) and disturbed sleep are common, often underrecognized, comorbidities in people with cystic fibrosis (pwCF). OBJECTIVES: We studied the effect of CFTR triple combination therapy elexacaftor/tezacaftor/ivacaftor (ELX/TEZ/IVA) on sleep in pwCF. METHOD: This was a prospective, observational sleep study in clinically stable adult pwCF. All participants underwent overnight polysomnography (PSG), before (T0) and after (T1) initiation of CFTR modulator therapy with ELX/TEZ/IVA. In addition, pulmonary function tests, calculation of BMI, and sweat chloride testing were performed. RESULTS: Twenty-nine pwCF (mean age 32 ± 8 years; 15 female) participated in the study. Mean time between T0 and T1 was 194 ± 21 days. Total sleep time (TST) was 298 ± 40 min, with decreased sleep efficiency (SE) (76 ± 109) and increased sleep latency (SL) (73 ± 38 min). Sleep stages for NREM (N1-3) and REM sleep were within the normal range. Nocturnal respiratory events mainly occur during REM sleep (T0: AHI REM 8.3 ± 9.0/h; ODI REM 9.4 ± 10.6/h), whereas the overall AHI was normal (3.6 ± 3.7/h). After initiation of ELX/TEZ/IVA, we saw significant improvements in ppFEV1 (p < 0.001) and BMI (p < 0.001) and a reduction in sweat chloride levels (p < 0.001). In parallel, there was a reduction in AHI (p = 0.003), ODI (p = 0.001), and nocturnal respiratory rate (p < 0.001), both in total, REM and NREM sleep. Neither TST, SL, SE, nor sleep architecture was influenced (all p > 0.05). CONCLUSIONS: Initiation of ELX/TEZ/IVA resulted in significant improvements in SDB in adult pwCF.

BACKGROUND: In this study we tested the hypothesis that in patients with cystic fibrosis (pwCF) respiratory rate (RR) is associated with antibiotic treatment, exacerbation status, forced expiratory volume in one second (FEV1) and C-reactive protein (CRP). METHODS: Between June 2018 and May 2019, we consecutively enrolled pwCF who were referred to our hospital. We determined RR and heart rate (HR) by using the minimal-impact system VitaLog during the hospital stay. Furthermore, we performed spirometry and evaluated CRP. RESULTS: We included 47 patients: 20 with pulmonary exacerbation and 27 without. RR decreased in patients with exacerbation (27.5/min (6.0/min) vs. 24.4/min (6.0/min), p = 0.004) and in patients with non-exacerbation (22.5/min (5.0/min) vs. 20.9/min (3.5/min), p = 0.024). Patients with exacerbation showed higher RR than patients with non-exacerbation both at the beginning (p = 0.004) and at the end of their hospital stay (p = 0.023). During the hospital stay, HR did not change in the total cohort (66.8/min (11.0/min) vs. 66.6/min (12.0/min), p = 0.440). Furthermore, we did not find significant differences between patients with exacerbation and patients with non-exacerbation (67.0/min (12.5/min) vs. 66.5/min (10.8/min), p = 0.658). We observed a correlation of ρ = -0.36 between RR and FEV1. Moreover, we found a correlation of ρ = 0.52 between RR and CRP. CONCLUSION: In pwCF requiring intravenous therapy, respiratory rate is higher at their hospital admittance and decreased by the time of discharge; it is also associated with C-reactive protein. Monitoring RR could provide important information about the overall clinical conditions of pwCF.

OBJECTIVES: Persistent lymph nodes infiltration after neoadjuvant treatment remains a controversial topic in the treatment of stage III non-small-cell lung cancer (NSCLC). The aim of this study is to identify subgroups with persistent N2 disease, who could experience survival benefit from the addition of surgery. METHODS: A retrospective mono-institutional study was conducted to analyse all patients with a final histopathology of NSCLC and persistent mediastinal disease after induction chemotherapy or chemoradiotherapy and surgery from January 1998 to June 2015. RESULTS: A total of 145 patients (93 men, 52 women) fulfilled the inclusion criteria. The median age was 60 years (range 38-78). A total of 82 (56.5%) patients received a lobectomy, 48 (33.1%) a pneumonectomy, 11 (7.6%) a bilobectomy and 4 (2.6%) an anatomical segmentectomy; 128 (88.3%) were completely resected (R0). Operative mortality was 2.6% (4 patients), and morbidity was 35.2% (51 patients). Overall survival at 5 years was 47.3% (n = 19) for single N2 (skip), 30.2% (n = 16) for single N2 and N1 lymph nodes and under 5% (n = 1) for multiple mediastinal stations disease. Overall survival at 5 years after lobectomy/bilobectomy was not statistically different than after pneumonectomy (33.5% vs 20.5%, P = 0.082). Disease-free survival at 5 years was 30.6% (n = 6) for ypN2a1, 23.4% (n = 7) for ypN2a2 and under 5% (n = 1) for ypN2b status. CONCLUSIONS: Lobectomy or bilobectomy has to be taken into account as a potentially curative option with promising long-term results for patients after induction treatment and persistent single-station N2 involvement (skip or additionally N1 status). TRIAL REGISTRY NUMBER: 14-6138-BO.

Thymic epithelial tumors are the most common mediastinal tumors. Surgery is the mainstay of treatment and complete resection provides the best survival rate. However, advanced tumors often require multimodality treatment and thus we analyzed the prognostic potential of routine circulating biomarkers that might help to risk-stratify patients beyond tumor stage and histology. Preoperative values for white blood cell count (WBC), C-reactive protein (CRP) and lactate dehydrogenase (LDH) were analyzed in 220 thymic epithelial tumor patients operated between 1999 and 2018. Increased CRP levels (>1 mg/dl) were significantly more often measured in thymic carcinoma and neuroendocrine tumors when compared to thymoma. LDH serum activity was higher in thymic neuroendocrine tumors when compared to thymoma or thymic carcinoma. The median disease specific survival was significantly longer in thymoma cases than in thymic carcinoma and neuroendocrine tumors. Increased preoperative LDH level (>240 U/L) associated with shorter survival in thymus carcinoma (HR 4.76, p = 0.0299). In summary, higher CRP associated with carcinoma and neuroendocrine tumors, while LDH increased primarily in neuroendocrine tumors suggesting that biomarker analysis should be performed in a histology specific manner. Importantly, preoperative serum LDH might be a prognosticator in thymic carcinoma and may help to risk stratify surgically treated patients in multimodal treatment regimens.

PURPOSE: In our study we aimed to analyze sleep variability and activity in patients with cystic fibrosis (CF) during their hospital stay. METHODS: Forty-three CF patients were recruited and have been divided into two subgroups: exacerbated (n = 18) and non-exacerbated (n = 25). During the course of their hospital stay we used VitaLog, a minimal-impact biomotion device, in order to determine total sleep time (TST), time in bed (TIB), sleep efficiency (SE) and intra patient standard deviation (IPSD) of TST. RESULTS: TST was 5.1 h ± 1.5 h and ranged from 0.6h to 7.9 h.TIB was 17.7 h ± 3.8 h and ranged from 5.6h to 23.9 h. SE was 70.0% ± 17.0% and ranged from 13.6% to 98.5%. TST was higher in non-exacerbated patients (5.3 h ± 1.4 h vs. 4.8 h ± 1.6 h, p = 0.008) whereas TIB was lower in non-exacerbated patients (17.0 h ± 3.7 h vs. 18.5 h ± 3.8 h, p = 0.002). We also found that SE was better in non-exacerbated patients (73.1% ± 14.6% vs. 66.6% ± 18.8%, p = 0.002). Furthermore, we observed that IPSD of TST was higher in exacerbated patients (1.3 h ± 0.5 h vs. 0.9 h ± 0.4 h, p = 0.004). CONCLUSION: In general, in CF patients TST was short and SE poor during the night. Furthermore, in the course of their hospital stay patients showed low activity. In exacerbated patients sleep quality was lower compared to non-exacerbated patients.

PURPOSE: In this proof of principle study, we evaluated the diagnostic accuracy of the novel Nox BodySleepTM 1.0 algorithm (Nox Medical, Iceland) for the estimation of disease severity and sleep stages based on features extracted from actigraphy and respiratory inductance plethysmography (RIP) belts. Validation was performed against in-lab polysomnography (PSG) in patients with sleep-disordered breathing (SDB). METHODS: Patients received PSG according to AASM. Sleep stages were manually scored using the AASM criteria and the recording was evaluated by the novel algorithm. The results were analyzed by descriptive statistics methods (IBM SPSS Statistics 25.0). RESULTS: We found a strong Pearson correlation (r=0.91) with a bias of 0.2/h for AHI estimation as well as a good correlation (r=0.81) and an overestimation of 14 min for total sleep time (TST). Sleep efficiency (SE) was also valued with a good Pearson correlation (r=0.73) and an overestimation of 2.1%. Wake epochs were estimated with a sensitivity of 0.65 and a specificity of 0.59 while REM and non-REM (NREM) phases were evaluated a sensitivity of 0.72 and 0.74, respectively. Specificity was 0.74 for NREM and 0.68 for REM. Additionally, a Cohen's kappa of 0.62 was found for this 3-class classification problem. CONCLUSION: The algorithm shows a moderate diagnostic accuracy for the estimation of sleep. In addition, the algorithm determines the AHI with good agreement with the manual scoring and it shows good diagnostic accuracy in estimating wake-sleep transition. The presented algorithm seems to be an appropriate tool to increase the diagnostic accuracy of portable monitoring. The validated diagnostic algorithm promises a more appropriate and cost-effective method if integrated in out-of-center (OOC) testing of patients with suspicion for SDB.

PURPOSE: In this study, we assessed the diagnostic accuracy of the device VitaLog (SWG Sportwerk GmbH & Co. KG, Dortmund, Germany) for estimation of respiratory rate (RR) variability. METHODS: VitaLog is a minimal-contact biomotion device that is placed under the mattress topper. It senses respiratory effort and body movement using a piezoelectric sensor. Diagnostic accuracy was determined in 103 patients referred to our sleep laboratory for suspected sleep-disordered breathing (SDB). SDB was defined by AHI ≥ 15/h. Results provided by VitaLog were compared with nasal flow measurement obtained by polysomnography (PSG). RESULTS: Diagnostic accuracy of VitaLog was excellent. We obtained a correlation of r = 0.99 and a bias of 0.2 cycles per minute (cpm) between VitaLog and PSG-provided nasal flow. Detection RR variability worked nearly identically in patients with and without SDB. CONCLUSION: VitaLog is an appropriate method for determination of RR variability based on a minimal-contact biomotion sensor. This device is easy to handle, available at low cost, and suitable for long-term monitoring in the hospital or at home.

Cognitive functioning after transplantation, which could influence medication compliance and independence, has not been well studied. This study investigated cognitive impairment after lung transplantation. Patients undergoing bilateral transplant between March 2013 and October 2015 underwent comprehensive neuropsychological assessment at 60.1 ± 44.1 months post-transplantation: verbal memory (Auditory-Verbal Learning Test, digit span forward), visual memory (Corsi Block-Tapping Test forward, Benton Visual Retention Test), concentration/speed of processing/attention (D2 Test of Attention, Trail Making Test (TMT) A, Grooved Pegboard), and executive functioning (TMT B, Stroop Color-Word Test, semantic and phonematic verbal fluency, digit span backward, Corsi Block-Tapping Test backward). Mean scores were compared with a normative dataset using a one-sample t-test. A cognitive domain was judged impaired if the score on two or more domain-specific tests was greater than one standard deviation below the normative dataset age range mean. Of 124 lung transplant recipients (51% male, 54.3 ± 9.0 years), 70% showed cognitive impairment in one or more domains. Executive function was most often impaired (78% of recipients not within the age range) followed by verbal memory impairment (72% not within the age range). Cognitive function reductions were largely independent of age, gender, education, immunosuppressive medications, and time since transplantation. The findings show that cognitive impairment is common after lung transplantation and should be subject to rehabilitation and psychological resilience strategies.

BACKGROUND: Large cell neuroendocrine carcinomas (LCNEC) are rare pulmonary malignancies. Reported survival rates are heterogeneous and the optimal therapeutic strategy is still debated. The prognosis of LCNEC is generally inferior compared to other non-small lung cancers. In early stages, surgery is recommended but might not be sufficient alone. METHODS: We retrospectively analyzed all consecutive LCNEC patients operated at three institutions with curative intent between May 2005 and January 2017. Data retrieved from individual clinical databases were analyzed with the aim to identify prognostic parameters. RESULTS: A total of 251 patients with LCNEC underwent curative intent surgery during the observation period. The median age was 64 years, 156 patients (62.2%) were male and 88.4% were smokers. The pathologic AJCC stage was I in 136 patients, II in 77, III in 33, and IV in 5 patients. Median follow-up was 26 months. Lymphatic vessel invasion (P=0.031) was identified as significant prognostic factor by multivariable analysis. There was a trend towards decreased survival in patients with blood vessel invasion (P=0.067). Even in earlier tumor stages, adjuvant chemotherapy had a positive effect on survival. The overall 1-, 3- and 5-year survival rates were 79.2%, 48.6% and 38.8% respectively. CONCLUSIONS: Lymphatic invasion (L1) is an independent prognostic factor. Surgery in LCNEC is beneficial in early tumor stages and platinum-based adjuvant chemotherapy may help in achieving better long-term outcomes resulting in most obvious survival differences in stage Ib.
RESUMO
OBJECTIVES: For early stage non-small cell lung cancer (NSCLC) retrospective data of functionally compromised patients undergoing segmentectomy showed equal outcomes for perioperative complications and quality of life (QoL) compared with lobectomy patients. However no prospectively randomized data comparing patients eligible for both procedures are available. MATERIALS AND METHODS: We conducted a prospective, randomized, multicenter phase III trial and investigated perioperative complications and QoL in patients with NSCLC stage IA (7th edition) undergoing segmentectomy versus lobectomy. The EORTC Questionnaire Core-30 (QLQ C-30) supplemented by thirteen-item lung cancer-specific module (LC13) was assessed before surgery, at discharge, 6 weeks, 3, 6 and 12 months post-surgery. RESULTS: 108 patients with verified or suspected NSCLC up to 2â¯cm diameter were enrolled, whereby 54 were assigned to lobectomy and 54 to segmentectomy. Due to nodal disease, tumor size and surgical reasons estimated during the operation, eight patients of the segmentectomy group received a lobectomy. In hospital and 90 days mortality was 0% in both groups. Perioperative complications were observed in 6 (11.3%) patients after segmentectomy and in 8 patients (14.8%) after lobectomy (pâ¯=â¯0.563), while the 90-day morbidity were 17% and 25.9% (9 and 14 patients), respectively (pâ¯=â¯0.452). Twelve months after surgery, there was a significant deterioration to the baselines of physical (pâ¯<â¯0.001) and cognitive functioning (pâ¯=â¯0.025), dyspnea (pâ¯<â¯0.001) and fatigue (pâ¯=â¯0.003) in the lobectomy group. Dyspnea showed a faster recovery in the segmentectomy compared to lobectomy group with statistical significance (pâ¯=â¯0.016 after 12 months). CONCLUSION: In patients with early-stage NSCLC, segmentectomy is associated with a statistically not significant lower perioperative morbidity and appears to provide a superior recovery in QoL compared with lobectomy patients.

BACKGROUND: The use of 22- or 21-gauge (G) endobronchial ultrasound (EBUS) needles are recommended for lung cancer diagnosis and staging. Performance of detailed molecular workup and programmed death ligand 1 (PD-L1) staining in lung cancer patients increases the demand for tissue. The aim of this prospective, randomized two-center trial was to compare 19-G and 22-G EBUS needles regarding tissue quality, diagnostic yield, feasibility, safety, performance, and blood content. PATIENTS AND METHODS: Patients with a computed tomography scan indicative of lung cancer with mediastinal or hilar lymph node metastases were prospectively enrolled and randomized for the use of either a 19-G or a 22-G EBUS needle. A blood content score from 0 to 2 was applied. Samples were weighed, tumor cells were counted per slide, and complications and final diagnoses were documented. RESULTS: We enrolled 107 patients (53 [49.5%] in the 19-G group/54 [50.5%] in the 22-G group) and samples were weighed immediately after performing EBUS. Samples obtained with a 19-G needle contained significantly more tissue (P = .0119). Non-small-cell lung cancer-infiltrated EBUS samples contained significantly more tumor cells when sampled with a 19-G needle (P = .0312). The diagnostic yield was equally adequate in both groups. Four moderate EBUS-related bleedings occurred (2 per group), hemostasis was rapidly achieved in all cases. Further complications did not occur. CONCLUSION: Endobronchial ultrasound-guided transbronchial needle aspirations with a 19-G needle contain significantly more tissue and tumor cells per slide with a safety profile similar to 22-G needles. Further research is needed to investigate the relevance of this finding in terms of molecular analyses and PD-L1 staining.

BACKGROUND: Thymic epithelial and neuroendocrine carcinomas are rare malignancies, and only a few prognosticators are defined. Surgery is the mainstay of treatment, and complete resection contributes to superior outcome. Systematic lymph node dissection is not routinely performed in thymic malignancies. The aim of this study was to assess the impact of histologically confirmed lymph node metastases on the outcome after thymectomy. METHODS: We identified 53 patients with thymic epithelial or neuroendocrine carcinomas who underwent surgical resection at our center between 1999 and 2016. The clinical follow-up was retrospectively collected, and the impact of clinicopathologic factors on overall survival was analyzed. RESULTS: Ninety-one percent of the patients were treated taking a multimodal approach. Median overall survival was 11.3 years. Lymph node metastases were identified in 16 patients (30.2%; 11 pN1 and 5 pN2). Lymph node metastasis was associated with inferior overall survival (hazard ratio [HR] 3.03, 95% confidence interval [CI]: 1.03 to 8.87, p = 0.044). Masaoka-Koga stage (4 versus 1 to 3) was another significant prognosticator (HR 7.01, 95% CI: 2.52 to 19.50, p = 0.0002). Organ metastases were present in 18 patients at the time of thymectomy and were associated with inferior outcome (HR 5.8, 95% CI: 2.04 to 16.79, p = 0.001). CONCLUSIONS: This retrospective, single-center analysis demonstrates a high rate of lymph node metastasis in resectable thymic neuroendocrine tumors or carcinomas. Positive lymph nodes are associated with an inferior outcome. Prospective studies are warranted to explore whether this outcome can be improved by systematic lymphadenectomy and adjuvant therapies. Nevertheless, lymphadenectomy provides optimal staging and should be a routine part of surgery for patients with thymic malignancies.

The prevalence of sleep-disordered breathing (SDB) after lung transplantation (LTX) is high. It is well-established that SDB is associated with decreased health-related quality of life (HRQoL), but the impact of SDB on exercise capacity is less clear. In this study we investigated HRQoL and exercise capacity in LTX recipients with or without SDB. In addition, we also investigated associations between sleep parameters and both HRQoL and exercise capacity. There were 53 stable LTX recipients (age > 18 years, 31 males, time from LTX 9-120 months) enrolled into the study. They all underwent polysomnography examination. HRQoL was assessed using the Short Form-36 (SF-36). Exercise capacity was measured using the 6-min walk test and cardiopulmonary exercise testing (CPET). We found inverse correlations between severity of SDB and both the predicted maximal workload (r = 0.24, p = 0.04) and maximal oxygen uptake (r = -0.26, p = 0.03) during CPET. Relative oxygen uptake positively correlated with sleep efficiency (r = 0.27, p = 0.03). SF-36 scores did not differ between patients with and without SDB, and were not significantly associated with SDB parameters. In conclusion, the presence of SDB is associated with a slight reduction in maximal exercise capacity in LTX recipients, and there is no appreciable relationship between SDB and HRQoL.

BACKGROUND: Patients with cystic fibrosis (CF) are highly susceptible to infection and colonization of pulmonary epithelia. Repeated and chronic infections may affect disease course and efficacy of host immune protection. Higher Interleukin (IL)-7 serum levels, indicating impaired T-cell response to IL-7, have been described for chronic viral and mycobacterial infections. METHODS: Time course measures of IL-7 serum concentrations in patients with CF (nâ¯=â¯164; nâ¯=â¯78 for the second time point) and healthy controls (nâ¯=â¯60) were done. CF patients were characterized for disease severity parameters as well as infection status and association with IL-7 serum levels was determined. RESULTS: CF patients had significantly higher IL-7 serum concentrations as compared to healthy controls (9.79â¯pg/ml, IQR 6.76-13.6 versus 4.55â¯pg/ml, IQR 2.76-9.51, pâ¯<â¯.001). IL-7 serum levels were negatively correlated with individual CF patient's BMI (râ¯=â¯-0.19, pâ¯=â¯.021) and a tendency of increased IL-7 levels in Staphylococcus aureus infected CF patients was found. Linear regression of multiple parameters revealed significant negative correlation of FEV1%pred with IL-7 serum concentrations in patients with CF (ß-coefficient: -0.04, 95% confidence interval [-0.08; -0.003], pâ¯=â¯.034). Time course analyses after 1â¯year +/- 6â¯months showed increased IL-7 serum levels (time point 1:9.26â¯pg/ml, IQR 6.94-13.12 time point 2:10.86â¯pg/ml, IQR 9.14-14.76, pâ¯=â¯.016) that correlated negatively with decreased FEV1%pred during CF disease course. CONCLUSIONS: High IL-7 serum levels were found in CF patients and correlated with impaired lung function during CF disease course. As a candidate biomarker of T-cell dysfunction, higher IL-7 serum level may also indicate worsened immune competence of patients with CF.

Objective: To evaluate two standard procedure-specific pain regimens and to assess independent predictors for higher pain intensity after thoracic surgery. Methods: Patients received either oral opioid analgesia (Opioid Group) or epidural analgesia and were then bridged to systemic opioid analgesia (EDA + O Group) in this retrospective observational study. Medical history, discharge letters, anesthetic protocols, and pain protocols were evaluated in 621 patients after open thoracotomy and assessed with a stepward back elimination in a multivariate logistic regression model. Results: Data of 621 thoracotomies in 2014 were analyzed, 309 patients in the Opioid Group and 312 patients in the EDA + O Group. Pain scores at rest and on coughing were significantly lower in the EDA + O Group on postoperative days (PODs) 1-4 (P < 0.001). Stepwise backward elimination in multivariate logistic regression identified preexisting pain disease (P = 0.034), no epidural analgesia (P < 0.001), opioids in preoperative pain therapy (P < 0.001), and antidepressant medication (P = 0.003) as independent risk factors for higher pain intensity at rest on PODs 1-4. Same on PODs 5-8 with regard to opioids in preoperative pain therapy (P < 0.001) and antidepressant medication (P = 0.018). Moreover, on PODs 5-8, male gender had a lower risk (P < 0.003) for pain, and preexisting musculosceletal disease had a lower risk for more postoperative pain (P = 0.009). On coughing, male gender and younger age proved to have a lower risk for postoperative pain on PODs 1-8 and on PODs 1-4, respectively. Opioids in preexisting pain therapy and antidepressant medication were identified as risk factors for pain on PODs 1-8 on coughing, and pain disease was identified as a risk factor for more pain on PODs 1-4 (P = 0.041). Moreover, preexisting cardiac disease indicated more pain on PODs 1-4 (P = 0.05), and musculoskeletal disease and neurological disease indicated more pain on PODs 5-8 (P = 0.041, and P = 0.023). Conclusions: We present data on independent risk factors for higher pain intensity during recovery after thoracotomy. The lack of postoperative epidural analgesia, female gender, preexisting opioid pain therapy, and chronic pain are the strongest risk factors for higher pain intensity. Antidepressant medication was identified as an independent risk factor at rest and on coughing on all PODs. Study limitations: The study design is retrospective.

INTRODUCTION: Patients after lung transplantation (LuTx) were found to present oral health deficiencies. The investigation of potentially underlying or influencing factors appears to be of clinical relevance. OBJECTIVES: Aim of this study was to evaluate the oral health related quality of life (OHRQoL) in a group of patients after LuTx and compare this to a healthy control group (HC). Furthermore, the influence of dental and periodontal condition, as well as specific factors like immunosuppression, time after LuTx and causal underlying disease should be investigated. METHODS: The OHRQoL was assessed using the German short form of the Oral Health Impact Profile (OHIP G14). Dental examination included the decayed (D-), missing (M-), and filled (F-) teeth index (DMF-T). Periodontal condition was classified based on clinical attachment loss and/or pocket depth as no/mild or moderate/severe periodontitis. STATISTICAL ANALYSIS: Mann-Whitney-U-test, Kruskal-Wallis test (P < .05). RESULTS: A total of 60 patients after LuTx and 70 HC were included. The DMF-T, D-T, and M-T as well as periodontal disease severity was significantly higher in LuTx group (P < .01). The OHIP G14 differed neither clinically relevant, nor statistically significant (LuTx: 1.70 ± 2.70, HC: 1.54 ± 2.86, P = .15). While in HC the DMF-T, M-T, and periodontal condition had an influence on OHIP G14 values (P < .05), in LuTx no influence was detected for dental and periodontal condition as well as specific factors investigated. CONCLUSIONS: The oral health perception of LuTx patients does not reflect the apparent oral health deficiencies. Consequently, sensitization and motivation for an increased dental behavior is needed.

BACKGROUND: Dental status has been implicated in several systemic inflammatory diseases and is a potential focus for systemic infections. Therefore, most lung-transplant centers have recommendations regarding pre-transplant dental care and follow-up, but there are no official clinical guidelines. To date there is little information on oral health status in lung transplant (LTx) recipients. The aim of this study was to systematically assess oral health status in LTx recipients. OBJECTIVES: The aim of this study was to assess oral health status, including periodontal disease, oral health behavior, and awareness of the need for good oral health after LTx. METHODS: LTx recipients were recruited during follow-up outpatient visits at a university clinic transplant unit. Oral health status was quantified using the count of Decayed, Missing, and Filled Teeth (DMF-T) and the grade of periodontal disease was measured by probing depth. Patients' oral health behavior was assessed using a questionnaire. RESULTS: Seventy-three patients were included at 5.8 ± 3.4 years after lung transplantation. The mean DMF-T was 21.9 ± 5.5. Patients with cystic fibrosis as the indication for transplantation had a significantly lower DMF-T than patients with chronic obstructive pulmonary disease as the transplant indication. Of the 66 patients with teeth, 97% had moderate or severe periodontal disease. The prevalence of moderate or severe periodontal disease was significantly higher in LTx recipients (mean age 55.9 years) compared with older individuals (age 65-74 years) from the German general population (P < .005). CONCLUSIONS: This single center study shows deficits in oral health and oral health behavior in patients after LTx. There is a strong need for interdisciplinary collaboration and clinical guidelines to foster better oral health education of the transplant recipient and better oral health.

PURPOSE: Recent studies found that the non-contact screening device SleepMinder (ResMed Sensor Technologies, Dublin, Ireland) detects sleep-disordered breathing (SDB) with high diagnostic accuracy in cohorts suspected of this disorder. However, it was reported that in patients with periodic limb movement in sleep (PLMS), this non-contact device overestimates the apnea-hypopnea index (AHI). We aimed to overcome this limitation by introducing the novel sleep disorder index (SDI) which is sum of the AHI and the period limb movement index (PLMI). METHODS: Between January 2011 and December 2013, we studied a mixed cohort of 57 patients (31 OSA, 19 PLMS). The easy-to-use non-contact device emits a very weak electromagnetic radiation and detects body movement by measuring the Doppler effect. We interpreted the device-generated movement index as the SDI and validated the diagnostic accuracy against simultaneous application of the gold-standard polysomnography (PSG). RESULTS: We found that the SDI of the non-contact device correlated well with the sum of AHI and PLMI derived from PSG (r = 0.79, p = 0.01). For PSG-derived SDI cutoff ≥ 15/h, we obtained a sensitivity of 92.2% and a specificity of 95.8%. Positive likelihood ratio was 23.3 and negative likelihood ratio 0.03. CONCLUSIONS: The studied non-contact screening device detects accurately the combination of the sleep disorders SDB and/or PLM. However, further testing is required in order to specify the nature of the underlying sleep disorder. At the current stage of algorithm development, the clinical strength is that the studied non-contact device can be used as a rule-out screening device for SDB and PLM.
