RESUMO

BACKGROUND: Although the number of lung transplantations (LTx) performed worldwide for COVID-19 induced acute respiratory distress syndrome (ARDS) is still low, there is general agreement that this treatment can save a subgroup of most severly ill patients with irreversible lung damage. However, the true proportion of patients eligible for LTx, the overall outcome and the impact of LTx to the pandemic are unknown. METHODS: A retrospective analysis was performed using a nationwide registry of hospitalised patients with confirmed severe acute respiratory syndrome coronavirus type 2 (SARS-Cov-2) infection admitted between January 1, 2020 and May 30, 2021 in Austria. Patients referred to one of the two Austrian LTx centers were analyzed and grouped into patients accepted and rejected for LTx. Detailed outcome analysis was performed for all patients who received a LTx for post-COVID-19 ARDS and compared to patients who underwent LTx for other indications. RESULTS: Between January 1, 2020 and May 30, 2021, 39.485 patients were hospitalised for COVID-19 in Austria. 2323 required mechanical ventilation, 183 received extra-corporeal membrane oxygenation (ECMO) support. 106 patients with severe COVID-19 ARDS were referred for LTx. Of these, 19 (18%) underwent LTx. 30-day mortality after LTx was 0% for COVID-19 ARDS transplant recipients. With a median follow-up of 134 (47-450) days, 14/19 patients are alive. CONCLUSIONS: Early referral of ECMO patients to a LTx center is pivotal in order to select patients eligible for LTx. Transplantation offers excellent midterm outcomes and should be incorporated in the treatment algorithm of post-COVID-19 ARDS.

RESUMO

BACKGROUND: The aim of this retrospective analysis was to evaluate the clinical feasibility of the supraclavicular ultrasound-guided cannulation of the brachiocephalic vein in infants weighing less than 1500 g. METHODS: The ultrasound probe was placed in the supraclavicular region so as to obtain the optimum sonographic long-axis view of the brachiocephalic vein. By using an in-plane approach the brachiocephalic vein was cannulated by using a 24-gauge intravenous cannula under real-time ultrasound guidance into the vein followed by the insertion of a 2-French single lumen catheter using the Seldinger technique. RESULTS: Forty-six brachiocephalic vein cannulations in infants weighing between 0.55 and 1.5 kg (Median: 1.2; 95%-CI: 0.9-1.2) were included. Ultimate success rate was 89.1% (41 out of 46). One cannulation attempt was required in 30 (65.2%) patients, 2 in 6 (13%) and 3 in 5 (10.8%), respectively. Smaller weight babies did not require significantly more cannulation attempts. The probability of successful cannulation on the first attempt increased significantly from 40% (2010) to more than 80% (2019) over the time course of this series. Median catheter dwell time was 15 days (95%-CI: 9-20) with one catheter being removed prematurely after 8 days due to obstruction. CONCLUSION: Supracalvicular in-plane real-time ultrasound-guided cannulation of the brachiocephalic vein seems to be a convenient and feasible option to provide large-bore central venous access for very small and sick babies.

RESUMO

OBJECTIVE: Dysphagia is a common disorder in neurological and non-neurological intensive care unit (ICU) patients and can lead to aspiration pneumonia, prolonged ventilation, and delayed extubation. Dysphagia is an independent predictor of increased mortality. In dysphagic stroke patients with tracheotomy, the use of pharyngeal electric stimulation (PES), an emerging technique to treat dysphagia, has been shown to improve airway protection and shorten time to decannulation. The objective of this study was to determine whether patients who receive PES have a lower prevalence of pneumonia and frequency of reintubation. DESIGN: Secondary analysis of a non-blinded interventional subject sample from a large clinical study with a historical age, pathology, and severity-matched control group. SETTING: ICU of a tertiary care medical center. PATIENTS: In this pilot non-blinded study, a group of 15 intubated patients in a general and a neurologic ICU received PES while orally intubated during ICU stay. A control group (n = 25) matched for age, type, and region of pathology, and severity of illness expressed by Simplified Acute Physiology Score and Therapeutic Intervention Scoring System was used to compare for pneumonia and need for reintubation. MAIN RESULTS: Patients treated with PES had significantly lower prevalence of pneumonia (4 vs 21, p = 0.00046) and frequency of reintubation (0 vs 6, p = 0.046) when compared to controls. CONCLUSION: Although limited by its small size and non-blinded design, this is the first study demonstrating the benefits of PES in ICU patients still orally intubated, thus offering a potential new method to reduce morbidity, mortality, and economic burden in a mixed ICU population. In order to further investigate and strengthen our findings, a statistically powered, randomized controlled study is recommended.

RESUMO

BACKGROUND: The aim of this retrospective analysis was to evaluate the clinical effectiveness of the supraclavicular ultrasound-guided cannulation of the brachiocephalic vein in preterm infants. METHODS: The ultrasound probe was placed in the supraclavicular region so as to obtain the optimum sonographic long-axis view of the brachiocephalic vein. By using a strict in-plane approach the brachiocephalic vein was cannulated by advancing a 22- or 24-gauge iv cannula from lateral to medial under the long axis of the ultrasound probe under real-time ultrasound guidance into the vein. RESULTS: One hundred and forty-two cannulations in infants weighing between 0.59 and 2.5 kg (median: 2.1; CI: 2.0 to 2.2) were included. Ultimate success rate was 94% (134 of 142). One cannulation attempt was required in 100 (70%) patients, two attempts in 21 (15%), and three attempts in 13 (9%). The smaller the weight of the infant the more attempts were needed. More attempts also were needed for the right brachiocephalic vein, which was primarily targeted in 75 (53%) neonates. One (1%) inadvertent arterial puncture was noted. CONCLUSIONS: This supraclavicular, in-plane, real-time, ultrasound-guided cannulation of the brachiocephalic vein seems to be a convenient and effective method to insert central venous catheters in preterm infants.

RESUMO

BACKGROUND: The supraclavicular ultrasound (US)-guided cannulation of the brachiocephalic vein (BCV) is one option of central venous line placement in infants. AIM: The aim of this prospective study was to evaluate whether there was an association between the optimum ultrasonographic view as obtained of the entire longitudinal extension of the right BCV and the ease of supraclavicular cannulation when using a strict in-plane technique via a linear US probe in small infants. METHODS: The US probe was placed in the right supraclavicular region. If the optimum obtainable sonographic view presented the entire longitudinal extension of the right BCV demonstrating clearly its path caudally alongside the pleura, it was graded as I. If, however, only a circular view, i.e., the initial part of the right BCV was obtainable via US, it was graded as II. The right BCV was cannulated by advancing a 22-gauge i.v. cannula from lateral to medial strictly under the long axis of the US probe under direct US vision into the vein. RESULTS: Seventy-nine infants weighing between 0.8 and 4.5 kg (Median: 3.4 ± 0.09) were included. In 50 (63.3%) patients, the sonographic view was graded as I and in 29 (36.7%) as II. The proportion of patients successfully cannulated on the first attempt was significantly smaller in patients graded as II, i.e., circular, sonographic view of the right BCV than in patients graded as I, i.e., sonographic view of the entire longitudinal extension of the right BCV (41% vs 90%; chi-square analysis: P < 0.01). CONCLUSION: The sonographic view obtainable of the entire longitudinal extension of the right BCV resulted in significantly fewer required cannulation attempts.

RESUMO

Background: Glioblastoma multiforme (GBM) is a relatively rare type of brain tumour with an incidence rate around 6 per 100,000. Even with the widely practiced combination of radiotherapy with adjuvant temozolomide, the median overall survival remains low with just 13.5 to 16 months after diagnosis. Patients and Methods: We retrospectively reviewed the survival of a cohort of 15 consecutive, unselected patients with histopathologically confirmed glioblastoma multiforme (GBM) who received CBD (400 to 600 mg orally per day) in addition to standard therapy (maximum resection of the tumour followed by radio-chemotherapy). Results: Of 15 patients, seven (46.7%) are now living for at least 24 months, and four (26.7%) for at least 36 months. This is more than twice as long as has been previously reported in the literature. The mean overall survival is currently 24.2 months (median 21 months). Conclusion: CBD is a well supported co-medication and seems to prolong the survival of patients with glioblastoma multiforme.

RESUMO

BACKGROUND: Neurogenic dysphagia is common and has no definitive treatment. We assessed whether pharyngeal electrical stimulation (PES) is associated with reduced dysphagia. METHODS: The PHAryngeal electrical stimulation for treatment of neurogenic Dysphagia European Registry (PHADER) was a prospective single-arm observational cohort study. Participants were recruited with neurogenic dysphagia (comprising five groups - stroke not needing ventilation; stroke needing ventilation; ventilation acquired; traumatic brain injury; other neurological causes). PES was administered once daily for three days. The primary outcome was the validated dysphagia severity rating scale (DSRS, score best-worst 0-12) at 3 months. FINDINGS: Of 255 enrolled patients from 14 centres in Austria, Germany and UK, 10 failed screening. At baseline, mean (standard deviation) or median [interquartile range]: age 68 (14) years, male 71%, DSRS 11·4 (1·7), time from onset to treatment 32 [44] days; age, time and DSRS differed between diagnostic groups. Insertion of PES catheters was successfully inserted in 239/245 (98%) participants, and was typically easy taking 11·8 min. 9 participants withdrew before the end of treatment. DSRS improved significantly in all dysphagia groups, difference in means (95% confidence intervals, CI) from 0 to 3 months: stroke (n = 79) -6·7 (-7·8, -5·5), ventilated stroke (n = 98) -6·5 (-7·6, -5·5); ventilation acquired (n = 35) -6·6 (-8·4, -4·8); traumatic brain injury (n = 24) -4·5 (-6·6, -2·4). The results for DSRS were mirrored for instrumentally assessed penetration aspiration scale scores. DSRS improved in both supratentorial and infratentorial stroke, with no difference between them (p = 0·32). In previously ventilated participants with tracheotomy, DSRS improved more in participants who could be decannulated (n = 66) -7·5 (-8·6, -6·5) versus not decannulated (n = 33) -2·1 (-3·2, -1·0) (p<0·001). 74 serious adverse events (SAE) occurred in 60 participants with pneumonia (9·2%) the most frequent SAE. INTERPRETATION: In patients with neurogenic dysphagia, PES was safe and associated with reduced measures of dysphagia and penetration/aspiration. FUNDING: Phagenesis Ltd.

RESUMO

Grade IV glioblastoma multiforme is a deadly disease, with a median survival of around 14 to 16 months. Maximal resection followed by adjuvant radiochemotherapy has been the mainstay of treatment since many years, although survival is only extended by a few months. In recent years, an increasing number of data from in vitro and in vivo research with cannabinoids, particularly with the non-intoxicating cannabidiol (CBD), point to their potential role as tumour-inhibiting agents. Herein, a total of nine consecutive patients with brain tumours are described as case series; all patients received CBD in a daily dose of 400 mg concomitantly to the standard therapeutic procedure of maximal resection followed by radiochemotherapy. By the time of the submission of this article, all but one patient are still alive with a mean survival time of 22.3 months (range=7-47 months). This is longer than what would have been expected.
