Abstract
Study Objectives
The objective of this study was to assess the effectiveness of current treatment guidelines for restless legs syndrome (RLS) augmentation in patients on dopamine agonists ...(DAs) which recommend a cross-titration strategy to an alpha-2-delta ligand (A2D) and/or opioid.
Methods
Consecutive new consultations for RLS with both augmentation and active treatment with DAs at the time of initial assessment were included if followed >5 months. Clinical information from the semi-structured initial consultation, and subsequent visits until their most recent/final visit was extracted. Clinical Global Impression-Severity (CGI-S) and Clinical Global Impression-Improvement (CGI-I) scores were retrospectively determined by two independent evaluators.
Results
In the 63 patients with augmented RLS on DAs, followed for 5–59 months (mean = 28, SD = 14), the average age was 67.6 (SD = 9.8) and 63% were female. Mean duration of prior dopaminergic therapy was 11.6 years (SD = 6.7) and average pramipexole equivalent dose was 1.23 mg (SD = 1.22 mg). At baseline, RLS was “moderate-markedly” severe (CGI-S = 4.9). At the final/most recent visit, 78% (49/63) were classified as Responders (CGI-I ≤ 2, “Much” or “Very Much Improved”) with an average CGI-S of 2.4 (“borderline-mildly ill”). Responders (59%) were more likely to have discontinued DAs than Non-Responders (40%), and mean opioid doses were higher in Responders (39 vs 20 MME). No differences in baseline DA dose, final A2D dose, or iron therapy were observed between groups. Responders did have significantly more severe RLS, more sleep maintenance insomnia, and greater subjective daytime sleepiness at baseline (p < 0.05).
Conclusions
Guideline-based management is effective in most patients with augmented RLS on DAs.
A 60-year-old previously healthy man was admitted to hospital with COVID-19 pneumonia that was treated initially with noninvasive ventilation, steroids and antibiotics. Six weeks after admission, the ...patient remained dependent on oxygen, using a high-flow nasal cannula combined with a nonrebreather mask. Physical examination found proximal muscle wasting due to the long hospital stay. Computed tomography of his chest showed bilateral dense consolidations with superimposed interstitial and fibrotic changes. Because we thought the fibrosis was unlikely to resolve, we discussed the option of lung transplantation with him and his family, both of whom were interested in the procedure. An acute clinical deterioration subsequently led to his intubation, transfer to our extracorporeal life support centre and placement on veno-venous extracorporeal membrane oxygenation (V-V ECMO) as a bridge to transplantation. Seventeen days after ECMO cannulation, the patient underwent successful double lung transplantation with removal of the V-V ECMO immediately after transplant.
Extracorporeal life support (ECLS) is increasingly used to bridge deteriorating patients awaiting lung transplantation (LTx), however, few systematic descriptions of this practice exist. We therefore ...aimed to review our institutional experience over the past 10 years.
In this case series, we included all adults who received ECLS with the intent to bridge to LTx. Data were retrieved from patient charts and our institutional ECLS and transplant databases.
Between January 2006 and September 2016, 1111 LTx were performed in our institution. ECLS was used in 71 adults with the intention to bridge to LTx; of these, 11 (16%) were bridged to retransplantation. The median duration of ECLS before LTx was 10 days (range, 0-95). We used a single dual-lumen venous cannula in 23 patients (32%). Nine of 13 patients (69%) with pulmonary hypertension were bridged by central pulmonary artery to left atrium Novalung. Twenty-five patients (35%) were extubated while on ECLS and 26 patients (37%) were mobilized. Sixty-three patients (89%) survived to LTx. Survival by intention to treat was 66% (1 year), 58% (3 years) and 48% (5 years). Survival was significantly shorter in patients undergoing ECLS bridge to retransplantation compared with first LTx (median survival, 15 months (95% CI, 0-31) versus 60 months (95% CI, 37-83); P = .041).
In our center experience, ECLS bridge to first lung transplant leads to good short-term and long-term outcomes in carefully selected patients. In contrast, our data suggest that ECLS as a bridge to retransplantation should be used with caution.
Abstract
Introduction
Augmentation is a management dilemma in RLS patients on dopaminergic therapy. Understanding the clinical characteristics of such patients may assist in better management ...strategies.
Methods
Consecutive new consultations for RLS from 4/2016-6/2020 were identified from a single tertiary referral center in Boston, USA. Patients were included in this analysis if they had augmentation and current treatment with a dopamine agonist. Clinical information from initial consultation was collected. RLS severity at time of consultation was determined retrospectively with a modified IRLSSG severity score (0–12), assessing RLS symptom frequency (0–4), duration (0–4), and severity (0–4).
Results
Out of 209 referrals with RLS, 105 patients had augmentation, of whom 88 were on dopamine agonists at initial evaluation. Average age was 67 years (SD 11 years, range 39–88); 62 were female (59%). Mean duration of RLS symptoms was 27 years (SD 20), and 91% had symptoms > 10 years. Mean duration of dopamine agonist therapy was 11 years; 72% had previously been treated with pramipexole, 65% with ropinirole, 73% with rotigotine, and 16% with levodopa; 72% of patients had been treated with alpha-2-delta ligands, and 28% with opioids. Common comorbidities included obstructive sleep apnea (47%), obesity (49%), and depression (44%). Serotonergic medications were currently used by 25%. Of the 88 augmented patients on dopamine agonist therapy, 97% had earlier onset of symptoms and 33% had symptoms in both morning and afternoon; 53% reported anatomical extension. The mean modified IRLSSG score was 8.4 (SD 3.2). 66% of patients had either ferritin <75 mcg/L or transferrin saturation <20%. At the time of initial assessment, 49% were on pramipexole, 47% on rotigotine, 5% on rotigotine and 7% on levodopa: mean daily dopamine agonist dose was 1.23 mg (SD 1.20) of pramipexole equivalent. 37% were on alpha-2-delta ligands: mean daily dose 1014 mg (SD 830, median 700 mg) of gabapentin equivalent.
Conclusion
Higher than FDA-recommended dopamine agonist dosing and high prevalence of iron deficiency in patients with augmented RLS represent a treatment gap in the care of RLS patients in the community. Controlled studies of guideline-based therapy are indicated to determine optimal management of augmented RLS.

Many donor lungs do not meet current criteria for transplantation. In this study, ex vivo lung perfusion and ventilation allowed the successful transplantation of lungs that might otherwise have been ...considered unsuitable as transplants.
Lung transplantation is lifesaving for patients with end-stage lung diseases. However, the number of patients waiting for a lung transplant greatly exceeds the number of available donors. On average, only 15% of lungs from multiorgan donors are used for transplantation

Although virtual consultations have played an increasing role in delivery of healthcare, the COVID-19 pandemic has hastened their adoption. Furthermore, virtual consultations are now being adopted in ...areas that were previously considered unsuitable, including post-operative visits for patients undergoing major surgical procedures, and surveillance following cancer operations. This review aims to examine the feasibility, safety, and patient satisfaction with virtual follow-up appointments after cancer operations.
A systematic review was conducted along PRISMA guidelines. Studies where patients underwent surgical resection of a malignancy with at least one study arm describing virtual follow-ups were included. Studies were assessed for quality. Outcomes including adverse events, detection of recurrence and patient and provider satisfaction were assessed and compared for those undergoing virtual or in-person post-operative visits.
Eleven studies, with 3369 patients were included. Cancer types included were gynecological, colorectal, esophageal, lung, thyroid, breast, prostate and major HPB resections. Detection of recurrence and readmission rates were similar when comparing virtual consultations with in-person visits. Most studies showed high patient and healthcare provider satisfaction with virtual consultations following cancer resection. Concerns were raised about the integration of virtual consultations into workflows in fee-for-service settings, where reimbursement for virtual care may be an issue.
Virtual follow-up care can provide timely and safe consultations in surgical oncology. Virtual consultations are as safe as in-person visits for assessing complications and recurrence. Where appropriate, virtual consultations can safely be integrated into the post-operative care pathway for those undergoing resection of malignancy.
The use of virtual consultations has rapidly increased in recent years, particularly because of the COVID-19 pandemic. This systematic review demonstrates the safety and efficacy of virtual follow-ups in surgical oncology.
Ex-vivo lung perfusion (EVLP) can be used to extend overall lung preservation time by splitting one long cold ischaemic time into two shorter ones and interposing an additional EVLP time. We assessed ...the outcomes after clinical transplantation of lungs with more than 12 h of preservation time.
For this retrospective study, we searched the Toronto Lung Transplant Program database for patients who had received at least one lung transplant between Jan 1, 2006, and April 30, 2015, at a single hospital in Toronto, Canada. We split the identified patients into those with a total preservation time of more than 12 h and those with a total preservation time of less than 12 h to act as the control group. Total preservation time was defined as the sum of first cold ischaemic time, EVLP time, and second cold ischaemic time. We excluded patients if they had received a heart-lung transplant or were younger than 18 years. In bilateral lung transplantations, we used the longer preservation time of the two lungs for analysis. Lung preservation was done according to present standards of care and EVLP was done according to the Toronto EVLP technique. The primary outcomes were survival and International Society for Heart and Lung Transplantation Primary Graft Dysfunction (PGD) grade at 72 h post-transplantation. We compared outcomes with our control group using univariable and multivariable models.
We identified 906 patients who met eligibility criteria and had sufficient data for analysis (<12 h group n=809; mean lung preservation time 400·8 min SD 121·8 vs >12 h group n=97; 875·7 min 109·0). Median hospital and intensive-care unit length of stay were similar between the less than 12 h group and the more than 12 h group (hospital stay: 23 days 16-42 vs 25·5 days 17-50·25, p=0·60; intensive-care unit stay: 4 days 2-14 vs 4 days 2-16, p=0·53). PGD grade was also not different between the two groups at 72 h post-transplantation (p=0·85). There was also no difference in survival between the two groups as shown on Kaplan-Meier survival curves (p=0·61). Multivariable survival analysis using Cox's model showed increasing recipient age to be a significant variable affecting survival.
Extension of graft preservation time beyond 12 h with EVLP does not negatively affect early lung transplantation outcomes. Extension of clinical lung preservation times might allow for more transplantations to be done as a result of improved facilitation and increased flexibility around timing of lung transplantation operations.
