BACKGROUND
Frailty is common in adults with advanced lung disease and is associated with death before and after lung transplantation. We aimed to determine whether frailty changes from before to after the lung transplant.
METHODS
In a single-center, prospective cohort study among adults undergoing lung transplantation from 2010 to 2017, we assessed frailty by the Short Physical Performance Battery (SPPB; higher scores reflect less frailty) and Fried Frailty Phenotype (FFP; higher scores reflect greater frailty) before and repeatedly up to 36 months after transplant. We tested for changes in frailty scores over time using segmented mixed effects models, adjusting for age, sex, and diagnosis. We quantified the proportion of subjects transitioning between frailty states (frail vs not frail) from before to after the transplant.
RESULTS
In 246 subjects, changes in frailty occurred within the first 6 post-operative months and remained stable thereafter. The overall change in frailty was attributable to improvements among those subjects who were frail before transplant. They experienced a 5.1-point improvement in SPPB (95% confidence interval [CI] 4.6-5.7) and a 1.8-point improvement in FFP (95% CI -2.1 to -1.6) during the early period. Frailty by SPPB and FFP did not change in those who were not frail before transplant. Approximately 84% of survivors who were frail before transplant became not frail after transplant.
CONCLUSIONS
Pre-operative frailty resolves in many patients after lung transplantation. Because a large proportion of frailty may be attributable to advanced lung disease, frailty alone should not be an absolute contraindication to transplantation.

OBJECTIVE
To analyze contemporary urethroplasty trends and urethral stricture etiologies over a 7-year study period among urologists from a large multi-institutional surgical outcomes group.
METHODS
Review of a multi-institutional, prospectively maintained urethroplasty database was performed on 2098 anterior urethroplasties done between 2010 and 2017 by 10 surgeons. Stricture characteristics, including etiology, length, and anatomic location were analyzed and compared to urethroplasty type over the study period using chi-squared analysis to assess for linear trends within the group and by surgeon.
RESULTS
Average stricture lengths for bulbar (2.8 ± 1.8 cm), penile (3.6 ± 2.6 cm), and penile-bulbar strictures (8.7 ± 5.0) remained stable. The most common stricture etiology was idiopathic/unknown in all study years (63%). In the bulbar urethra, the group performed significantly (1) fewer excisional repairs (-31%) and more substitutional repairs (+78%); (2) of substitutional repairs, more grafts are being placed dorsally (+95%) vs ventrally (-75%) (3) of the bulbar excisional repairs, more are being performed without transection of the bulbar urethra (+430%); and in the penile urethra (4) the fasciocutaneous flap is in decline (-86%), while single-stage dorsal repairs are increasing (+280%).
CONCLUSION
Anterior urethroplasty techniques continue to evolve in the absence of robust clinical data or randomized controlled trials, with a general movement in this cohort toward an initial dorsal approach for most strictures. Inter- and intrasurgeon variability in the surgical management of similar strictures was noted, and the feasibility of any future randomized controlled trials, without apparent surgical equipoise, must be questioned.

Purpose
The incidence of brain metastases is increasing as a result of more routine diagnostic imaging and improved extracranial systemic treatment strategies. As noted in recent consensus guidelines, postoperative stereotactic radiosurgery (SRS) to the resection cavity has lower rates of local control than whole brain radiation therapy but improved cognitive outcomes. Further analyses are needed to improve local control and minimize toxicity.
Methods and materials
Patients receiving SRS to a resection cavity between 2006 and 2016 were retrospectively analyzed. Presurgical variables, including tumor location, diameter, dural/meningeal contact, and histology, were collected, as were SRS treatment parameters. Patients had routine follow-up with magnetic resonance imaging, and those noted to have local failure were further assessed for the recurrence location, distance from the target volume, and dosimetric characteristics.
Results
Overall, 82 patients and 85 resection cavities underwent postoperative SRS during the study period. Of these, 58 patients with 60 resection cavities with available follow-up magnetic resonance imaging scans were included in this analysis. With a median follow-up of 19.8 months, local recurrence occurred in 12 of the resection cavities for a 15% 1-year and 18% 2-year local recurrence rate. Pretreatment tumor volume contacted the dura/meninges in 100% of cavities with recurrence versus 67% of controlled cavities ( = .025). A total of 5 infield, 5 marginal, and 4 out-of-field recurrences were found, with a median distance to the centroid from the target volume of 3 mm. The addition of a 10-mm dural margin increased the target volume overlap with the recurrence contours for 10 of the 14 recurrences.
Conclusions
Dural contact was associated with an increased rate of recurrence for patients who received SRS to a surgical cavity, and the median distance of marginal recurrences from the target volume was 3 mm. These results provide evidence in support of recent consensus guidelines suggesting that additional dural margin on SRS volumes may benefit local control.

Delirium Risk Factors and Associated Outcomes in a Neurosurgical Cohort: A Case-Control Study.
2019
Authors: Morshed RA, Young JS, Safaee M, Sankaran S, Berger MS, McDermott MW, Hervey-Jumper SL
OBJECTIVE
There are limited reports examining delirium in cohorts of neurosurgical patients across inpatient settings without separation based on subspecialty distinction. It is of interest to identify consistent delirium risk factors across various cranial pathologies and inpatient settings that will inform future interventional studies.
METHODS
Delirium rates, patient and hospitalization risk factors, and clinical outcomes in 235 patients undergoing a cranial procedure were examined in a retrospective fashion.
RESULTS
Fifty-two (22.1%) patients experienced delirium during their hospital stay. Patient factors predictive of delirium on univariate logistic regression were older age, a diagnosis of hydrocephalus or intracranial infection, transfer from an outside hospital, and admission through the emergency department. Hospitalization factors predictive of delirium included longer length of intensive care unit (ICU) stay, abnormal sodium values preceding delirium, a new postoperative infection, and the presence of a neurologic deficit. Using recursive partitioning, age ≥72.56 years and ICU length of stay ≥5 days were identified as critical thresholds for predicting delirium (odds ratio [OR] 4.61 and 18.2, respectively). On multivariate logistic regression analysis, age (unit OR 1.05), length of ICU stay (unit OR 1.2), and a neurologic deficit (OR 5.4) were predictive of delirium. Furthermore, delirium was also significantly associated with a longer length of admission as well as decreased likelihood for discharge home.
CONCLUSIONS
Delirium is a frequent occurrence after neurosurgery with older age, longer ICU stay, and a neurologic deficit being consistent risk factors across inpatient settings. These results help identify at-risk patients for delirium on a neurosurgical service to enact interventions preemptively.
