ABSTRACT
Background: Palliative sedation requires no formal registration in Belgium. For euthanasia, however, there are clear guidelines in certain countries, including mandatory registration and evaluation of cases. Official guidelines have been developed for palliative sedation, but research still shows unskilled use of sedation and unclear demarcation between palliative sedation and euthanasia. Registration could be used to avoid unskilled use of sedation and to avoid use or abuse of sedation to hasten the patient's death (described as "slow/passive euthanasia"). Objective: To evaluate the current practice of palliative sedation and use of opioids and sedatives at the end of life by using a registration document. Design: Retrospective observational study. Setting/Subjects: We included all in-hospital deaths at an academic hospital in Belgium of patients (age ≥18 years) who had received parenteral opioids, benzodiazepines, barbiturates, or other anesthetics during the last 24 hours. Measurements: We investigated indications for palliative sedation, patients' and physicians' characteristics, types of medication used, and the decision-making process with the patients and family. The questionnaires were collected between July 9 and November 25, 2016. The study was approved by the Biomedical Ethics Committee of UZ Brussel (B.U.N. 1432016293). Results: In a population of 124 patients, refractory symptoms were reported in 94.4%. All patients received parenteral opioids (intravenously). Benzodiazepines were used in 51.6%. In 75.8%, physicians reported no change in treatment plan during end of life. Hastening death by increasing analgesics and/or sedatives was mentioned in 19.3%. The treatment plan was discussed with patients in 26.6% of cases. In 6 cases, an explicit intention to hasten death was mentioned; in 36 cases, doses of opioids/sedatives may not have been strictly proportional to symptoms. Conclusion: This Belgian study shows that objective reporting of palliative sedation can be used as a tool to ensure good clinical practice where patients receive the most appropriate end-of-life care, avoiding abusive and injudicious or unskilled use of sedation.

Patients recovered from a COVID-19 infection often report vague symptoms of fatigue or dyspnoea, comparable to the manifestations in patients with central sensitisation. The hypothesis was that central sensitisation could be the underlying common aetiology in both patient populations. This study explored the presence of symptoms of central sensitisation, and the association with functional status and health-related quality of life, in patients post COVID-19 infection. Patients who were previously infected with COVID-19 filled out the Central Sensitisation Inventory (CSI), the Post-COVID-19 Functional Status (PCFS) Scale and the EuroQol with five dimensions, through an online survey. Eventually, 567 persons completed the survey. In total, 29.73% of the persons had a score of <40/100 on the CSI and 70.26% had a score of ≥40/100. Regarding functional status, 7.34% had no functional limitations, 9.13% had negligible functional limitations, 37.30% reported slight functional limitations, 42.86% indicated moderate functional limitations and 3.37% reported severe functional limitations. Based on a one-way ANOVA test, there was a significant effect of PCFS Scale group level on the total CSI score (F(4,486) = 46.17, p < 0.001). This survey indicated the presence of symptoms of central sensitisation in more than 70% of patients post COVID-19 infection, suggesting towards the need for patient education and multimodal rehabilitation, to target nociplastic pain.
ABSTRACT
Continuous Intrathecal Drug Delivery through an implanted pump is a well-known therapeutic option for the management of chronic pain and severe disabling spasticity. To have a successful therapy, pump refills need to be performed at regular time intervals after implantation. In line with the increased applications of Hospital at Home, these refill procedures might be performed at the patient's home. The aim of this pilot study is to evaluate the feasibility, safety, and effectiveness of intrathecal pump refill procedures at home. Twenty patients were included whereby pump refill procedures were conducted at the patient's home. To enable contact with the hospital, a video connection was set-up. Tele-ultrasound was used as post-refill verification. All procedures were successfully performed with complete patient satisfaction. Ninety-five percent of the patients felt safe during the procedure, and 95% of the procedures felt safe according to the physician. All patients indicated that they preferred their next refill at home. The median time consumption for the physician/nurse at the patient's home was 26 min and for the researcher at the hospital 15 min. In light of quality enhancement programs and personalized care, it is important to continue urgent pain management procedures in a safe way, even during a pandemic.
ABSTRACT
BACKGROUND: Complicated (recurring or persistent) spontaneous pneumothorax requires intervention either by surgical or nonsurgical pleurodesis or other interventions. As for high-risk patients, aggressive interventions may be associated with morbidity, the safety and effectiveness of less aggressive alternative interventions like thoracoscopic talc pleurodesis (TTP) should be evaluated. METHODS: Data were extracted on patients who had undergone TTP for complicated spontaneous pneumothorax at Interventional Clinic, University Hospital, Brussels, Belgium. The complications, length of hospital stay, and success rate over a 24-month period were studied. RESULTS: A total of 41 TTP procedures were performed for 25 (61%) cases of primary spontaneous pneumothorax and for 16 (39%) cases of secondary spontaneous pneumothorax. Twenty-four cases were first episodes, whereas it was a recurrence in 17. Of 4 patients with blebs/bullae, 2 had recurrence after TTP.No patient had acute respiratory distress syndrome or any other serious complication after TTP. Recurrence rates after TTP in primary and secondary spontaneous pneumothorax were 9.5% and 25% at 24 months, respectively. The mean length of hospital stay after TTP was 3±3.2 days. CONCLUSIONS: TTP is a safe and effective intervention in complicated spontaneous pneumothorax.

BACKGROUND: Malignant pleural effusions (MPE) are a common and fatal complication in cancers including lung or breast cancers, or malignant pleural mesothelioma (MPM). MPE animal models and immunotherapy trials in MPM patients previously suggested defects of the cellular immunity in MPE. However only few observational studies of the immune response were done in MPM patients, using questionable control groups (transudate ). METHODS: We compared T cell populations evaluated by flow cytometry from blood and pleural effusion of untreated patients with MPM (n = 58), pleural metastasis of adenocarcinoma (n = 30) or with benign pleural lesions associated with asbestos exposure (n = 23). Blood and pleural fluid were also obtained from healthy subjects, providing normal values for T cell populations. RESULTS: Blood CD4+ or CD8+ T cells percentages were similar in all groups of patients or healthy subjects. Whereas pleural fluid from healthy controls contained mainly CD8+ T cells, benign or malignant pleural effusions included mainly CD4+ T cells. Effector memory T cells were the main T cell subpopulation in pleural fluid from healthy subjects. In contrast, there was a striking and selective recruitment of central memory CD4+ T cells in MPE, but not of effector cells CD8+ T cells or NK cells in the pleural fluid as one would expect in order to obtain an efficient immune response. CONCLUSIONS: Comparing for the first time MPE to pleural fluid from healthy subjects, we found a local defect in recruiting effector CD8+ T cells, which may be involved in the escape of tumor cells from immune response. Further studies are needed to characterize which subtypes of effector CD8+ T cells are involved, opening prospects for cell therapy in MPE and MPM.

The Endobronchial Valve for Emphysema Palliation Trial (VENT) was a multi-centre, prospective, randomised, controlled trial conducted to evaluate the safety and effectiveness of unilateral endobronchial valve (EBV) treatment. The purpose of this analysis was to assess outcomes in the previously unreported European VENT study cohort. Patients with advanced emphysema were randomly assigned (2:1) to receive Zephyr® (Pulmonx Inc., Redwood City, CA, USA) EBV treatment (n = 111) or medical management (n = 60). At 6 months, EBV patients demonstrated a significant improvement compared with the controls for mean ± SD change in forced expiratory volume in 1 s (7 ± 20% versus 0.5 ± 19%; p = 0.067), cycle ergometry (2 ± 14 W versus -3 ± 10 W; p = 0.04) and St George's Respiratory Questionnaire (-5 ± 14 points versus 0.3 ± 13 points; p = 0.047). At 12 months, the magnitude of the difference between groups for change from baseline was of similar magnitude to the differences seen at 6 months. Rates for complications did not differ significantly. EBV patients with computed tomography (CT) scans suggestive of complete fissure and lobar occlusion had a mean ± SD lobar volume reduction of -80 ± 30% and >50% met minimal clinical difference thresholds. The degree of emphysema heterogeneity did not preclude excellent outcomes. Unilateral lobar volume reduction using EBV treatment is safe and superior clinical results correlated with CT suggestive of complete fissures and successful lobar occlusion. Emphysema heterogeneity was not critical for determining positive outcomes.

Globalization of health care, flat medicine, cross-boarder health care, medical tourism, are all terms describing some, but not all, aspects of a growing trend: patients seeking health care provision abroad, and health care providers travelling abroad for temporary or permanent health care delivery services. This trend is a complex, bilateral and multifaceted phenomenon, which in our opinion, cannot be sustained in a single, comprehensive description. Individual hospitals have the unique opportunity to develop a model for appropriate action. The specific model created by the university hospital UZ Brussel is presented here.

OBJECTIVES: Essential hyperhidrosis (EH) is defined as excessive functioning of the sudomotor sweat system. Definitive treatment of choice is video-assisted thoracoscopic sympathetic interruption. Success rates are high, but compensatory hyperhidrosis (CH) remains a troublesome side effect. The aim of this study was to document patient satisfaction and side effects at least 6 months after thoracoscopic sympathicolysis. METHODS: Between 2001 and 2005, 246 patients underwent bilateral ablation of the sympathetic chain at the thoracic level T2, T3, and/or T4. Questionnaires using open questions and scoring systems were sent at least 6 months after procedure and were returned by 138 patients (56%). RESULTS: From the 138 patients (56 males/82 females), 39 suffered from cranial (±facial blushing), 34 from palmar, and 34 from axillary hyperhidrosis. Thirty-one patients were treated for a combination. No conversion to open surgery or deaths occurred. For the whole group, average quality of life was 4.5±2.5 before and 8.4±1.8 after surgery (P<.001). Ninety-one percent were very satisfied (score ≥7) and 80% showed an increased quality of life of ≥2. Compensatory sweating occurred in 76% of the patients, only 6% reported this as disabling. Comparing subgroups, a significant improvement in primary complaint score was found in 90%, 94%, and 91% for the T2, T3, and T4 patients, respectively. In the T4 group, the prevalence of CH was markedly lower (53%) and none of these patients were dissatisfied. CONCLUSION: Thoracoscopic ablation of the sympathetic chain is an effective treatment for EH; CH occurs in the majority of patients, but only rarely impairs postoperative quality of life.

BACKGROUND: Idiopathic tracheal stenosis (ITS) is a rare condition representing a difficult therapeutic challenge. Endoscopic management is a therapeutic option but long-term results are not established. The aim of this retrospective multicenter study was to analyze long-term outcome after endoscopic management of ITS. METHODS: Nine institutions involved in interventional bronchoscopy were contacted and asked to identify ITS endoscopically treated. A standard form was used to report the main characteristics and long-term outcome after endoscopic management. RESULTS: Twenty-three patients, 96% women, aged 45±16 years, were endoscopically treated for ITS. Time between first symptoms and diagnosis was 19±18 months. Bronchoscopy showed a weblike (61%) or complex (39%) stenosis, located in the upper part of the trachea, mainly in the cricoid area. Endoscopic treatment included mechanical dilation only (52%) or associated with laser or electrocoagulation (30%) and stent placement (18%). All procedures were efficient. The follow-up after endoscopic management was 41±34 months. The ITS recurrence occurred in 30% at 6 months, 59% at 2 years, and 87% at 5 years, with a delay of 14±16 months. The treatment of recurrence (n=13) included endoscopic management in 12 cases. CONCLUSIONS: Endoscopic management of ITS provides a safe and efficient therapeutic option but late recurrences are frequent and require long-term follow-up.

We report a case of a 22-year-old woman affected by catecholaminergic polymorphic ventricular tachycardia admitted to our hospital following multiple appropriate inefficacious defibrillator shocks. Left cardiac sympathetic denervation is proposed as a viable therapeutic option to solve such a delicate case history.
ABSTRACT
BACKGROUND: Fluorescein-enhanced autofluorescence thoracoscopy (FEAT) reveals regions of abnormal fluorescence in patients with primary spontaneous pneumothorax and in normal subjects. Some of these lesions are undetectable by white light thoracoscopy and it has been hypothesized that they represent underlying pleural and/or parenchymal abnormalities. OBJECTIVES: In order to standardize and evaluate this novel technique, we developed an animal model. METHODS: Six pigs underwent thoracoscopy after the inhalation of nebulized sodium fluorescein by either volume-controlled mechanical ventilation or spontaneous ventilation. Pleural cavity and lung surface were inspected by white light thoracoscopy and FEAT during a period of 90 min. Fluorescence intensities were quantified in pleura and in blood. Regions of interest were examined postmortem for a histological assessment of the lesions. RESULTS: FEAT lesions were observed in all animals, with a maximum intensity of the lesions 20-30 min after the onset of fluorescein administration. The plasma concentrations of sodium fluorescein reached a maximum after approximately 20 min. The microscopic findings suggest that fluorescein accumulates in the subpleural space of better ventilated lung areas. CONCLUSIONS: This is the first animal model using FEAT. Valuable information has been gathered but further investigations are required to explain the phenomena observed in humans and pigs.

Recurrent and persistent pleural exudates are common in clinical practice, and in a large number of patients, thoracocentesis and blind pleural biopsy procedures do not provide a definitive diagnosis. In the Western world, the majority of these exudates are malignant. Thoracoscopy today remains the gold standard technique in providing diagnosis and management in these cases. Other common indications include diagnosis and management of recurrent or refractory benign exudates or transudates, pleural based tumors and pleural thickening, selected cases of pleural empyema, and recurrent spontaneous primary and secondary pneumothorax. Major advantages of this technique are ease of application, high diagnostic accuracy and therapeutic efficacy, low cost, and excellent safety record comparable with flexible bronchoscopy. Thoracoscopy should be part of the routine training curriculum of respiratory physicians.

BACKGROUND: Interventional bronchoscopic procedures can re-establish airway patency in the majority of individuals suffering from endobronchial obstruction. However, literature provides limited data on the impact of these procedures on the individual's quality of life (QoL). OBJECTIVES: We evaluated the impact of interventional bronchoscopic procedures aimed at re-establishing airway patency on symptoms and QoL of individuals who do not receive concomitant chemotherapy or radiation therapy. METHODS: Over a 6-month period, we prospectively enrolled patients with symptomatic central airway obstruction related to malignancy and performed laser ablation, cryotherapy, and/or airway stenting in order to re-establish airway patency. QoL was evaluated by the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire at one day before, 7 days after, and 1 month after procedure. Dyspnea was also assessed by the Borg scale before the procedure and one day after. RESULTS: Final analysis could be performed on 83% (20/24) of the participants. Improvement in airway diameter was achieved in all patients, and >80% patency was established in 80% (16/20) of the patients. Dyspnea scores had improved in 85% of participants (p = 0.01). Thirteen patients experienced an improvement in QoL, although QoL scores remained stable for the group as a whole. CONCLUSION: Endoscopic procedures can effectively reduce dyspnea associated with malignant central airway obstruction, but this may not always translate into improvements in overall QoL. Administration of QoL questionnaires is feasible, and may help identify domains contributing to patient's decline, and thereby improve overall patient care.

BACKGROUND: To determine the prevalence of blebs or bullae using thoracoscopy in young healthy adults, and to compare patient characteristics among those with and without blebs. METHODS: Bilateral thoracoscopic evaluation of the lungs was performed in healthy individuals who were referred for thoracoscopic thoracic sympathectomy for essential hyperhidrosis. Participants were enrolled into a registry and followed for up to 9 years. RESULTS: Analysis was performed on 250 consecutive cases. Blebs were observed in 15 of 250 individuals (6%; male, n = 6; female, n = 9; mean age, 25.3 years; range, 15 to 51 years). Individuals with blebs had a significantly lower body mass index (BMI) [mean +/- SD, 20.7 +/- 2.4 kg/m(2) vs 22.7 +/- 3.4 kg/m(2); p = 0.027] when compared to individuals without blebs, whereas all other parameters were similar. Blebs were most prevalent among slim individuals (BMI < 22 kg/m(2)) who smoked (odds ratio, 5.9; 95% confidence interval, 1.19 to 29.20). CONCLUSION: Blebs were identified thoracoscopically in 6% of young healthy adults with no underlying lung disease. Low BMI in combination with smoking may have an important role in the development of pleural blebs in healthy young adults; however, these changes may not be responsible for future spontaneous pneumothoraces.

BACKGROUND: Lung volume reduction surgery is effective at improving lung function, quality of life, and mortality in carefully selected individuals with advanced emphysema. Recently, less invasive bronchoscopic approaches have been designed to utilize these principles while avoiding the associated perioperative risks. The Endobronchial Valve for Emphysema PalliatioN Trial (VENT) posits that occlusion of a single pulmonary lobe through bronchoscopically placed Zephyr endobronchial valves will effect significant improvements in lung function and exercise tolerance with an acceptable risk profile in advanced emphysema. METHODS: The trial design posted on Clinical trials.gov, on August 10, 2005 proposed an enrollment of 270 subjects. Inclusion criteria included: diagnosis of emphysema with forced expiratory volume in one second (FEV1) < 45% of predicted, hyperinflation (total lung capacity measured by body plethysmography > 100%; residual volume > 150% predicted), and heterogeneous emphysema defined using a quantitative chest computed tomography algorithm. Following standardized pulmonary rehabilitation, patients were randomized 2:1 to receive unilateral lobar placement of endobronchial valves plus optimal medical management or optimal medical management alone. The co-primary endpoint was the mean percent change in FEV1 and six minute walk distance at 180 days. Secondary end-points included mean percent change in St. George's Respiratory Questionnaire score and the mean absolute changes in the maximal work load measured by cycle ergometry, dyspnea (mMRC) score, and total oxygen use per day. Per patient response rates in clinically significant improvement/maintenance of FEV1 and six minute walk distance and technical success rates of valve placement were recorded. Apriori response predictors based on quantitative CT and lung physiology were defined. CONCLUSION: If endobronchial valves improve FEV1 and health status with an acceptable safety profile in advanced emphysema, they would offer a novel intervention for this progressive and debilitating disease. TRIAL REGISTRATION: ClinicalTrials.gov: NCT00129584.

BACKGROUND: Talc is the most effective chemical pleurodesis agent for patients with malignant pleural effusion. However, concerns have arisen about the safety of intrapleural application of talc, after reports of development of acute respiratory distress syndrome in 1-9% of treated patients. Our aim was to establish whether use of large-particle-size talc is safe in patients with malignant pleural effusion. METHODS: We did a multicentre, open-label, prospective cohort study of 558 patients with malignant pleural effusion who underwent thoracoscopy and talc poudrage with 4 g of calibrated French large-particle talc in 13 European hospitals, and one in South Africa. The primary endpoint was the occurrence of acute respiratory distress syndrome after talc pleurodesis. FINDINGS: No patients developed acute respiratory distress syndrome (frequency 0%, one-sided 95% CI 0-0.54%). 11 (2%) patients died within 30 days. Additionally, seven patients had non-fatal post-thoracoscopy complications (1.2%), including one case of respiratory failure due to unexplained bilateral pneumothorax. INTERPRETATION: Use of large-particle talc for pleurodesis in malignant pleural effusion is safe, and not associated with the development of acute respiratory distress syndrome.
