To rapidly communicate information on the global clinical effort against Covid-19, the Journal has initiated a series of case reports that offer important teaching points or novel findings. The case reports should be viewed as observations rather than as recommendations for evaluation or treatment. In the interest of timeliness, these reports are evaluated by in-house editors, with peer review reserved for key points as needed.

Objective: This report describes persistent symptoms associated with post-acute COVID-19 syndrome (PACS) and the impact of these symptoms on physical function, cognitive function, health-related quality of life, and participation. Design: This study used a cross-sectional observational study design. Patients attending Mount Sinai’s post-acute COVID-19 syndrome clinic completed surveys containing patient-reported outcomes. Results: A total of 156 patients completed the survey, at a median (range) time of 351 days (82–457 days) after COVID-19 infection. All patients were prevaccination. The most common persistent symptoms reported were fatigue (n = 128, 82%), brain fog (n = 105, 67%), and headache (n = 94, 60%). The most common triggers of symptom exacerbation were physical exertion (n = 134, 86%), stress (n = 107, 69%), and dehydration (n = 77, 49%). Increased levels of fatigue (Fatigue Severity Scale) and dyspnea (Medical Research Council) were reported, alongside reductions in levels of regularly completed physical activity. Ninety-eight patients (63%) scored for at least mild cognitive impairment (Neuro-Qol), and the domain of the EuroQol: 5 dimension, 5 level most impacted was Self-care, Anxiety/Depression and Usual Activities. Conclusions: Persistent symptoms associated with post-acute COVID-19 syndrome seem to impact physical and cognitive function, health-related quality of life, and participation in society. More research is needed to further clarify the relationship between COVID-19 infection and post-acute COVID-19 syndrome symptoms, the underlying mechanisms, and treatment options.

Subacute and chronic subdural hematomas are common and frequently recur after surgical evacuation. The effect of adjunctive middle meningeal artery embolization on the risk of reoperation remains unclear. In a prospective, multicenter, interventional, adaptive-design trial, we randomly assigned patients with symptomatic subacute or chronic subdural hematoma with an indication for surgical evacuation to undergo middle meningeal artery embolization plus surgery (treatment group) or surgery alone (control group). The primary end point was hematoma recurrence or progression that led to repeat surgery within 90 days after the index treatment. The clinical secondary end point was deterioration of neurologic function at 90 days, which was assessed with the modified Rankin scale in a noninferiority analysis (margin for risk difference, 15 percentage points). A total of 197 patients were randomly assigned to the treatment group and 203 to the control group. Surgery occurred before randomization in 136 of 400 patients (34.0%). Hematoma recurrence or progression leading to repeat surgery occurred in 8 patients (4.1%) in the treatment group, as compared with 23 patients (11.3%) in the control group (relative risk, 0.36; 95% confidence interval [CI], 0.11 to 0.80; P = 0.008). Functional deterioration occurred in 11.9% of the patients in the treatment group and in 9.8% of those in the control group (risk difference, 2.1 percentage points; 95% CI, -4.8 to 8.9). Mortality at 90 days was 5.1% in the treatment group and 3.0% in the control group. By 30 days, serious adverse events related to the embolization procedure had occurred in 4 patients (2.0%) in the treatment group, including disabling stroke in 2 patients; no additional events had occurred by 180 days. Among patients with symptomatic subacute or chronic subdural hematoma with an indication for surgical evacuation, middle meningeal artery embolization plus surgery was associated with a lower risk of hematoma recurrence or progression leading to reoperation than surgery alone. Further study is needed to evaluate the safety of middle meningeal artery embolization in the management of subdural hematoma.

Background and Purpose—: Minimally invasive surgery (MIS) for intracerebral hemorrhage (ICH) has been evaluated in numerous clinical trials. Although meta-analyses for this strategy have been performed in the past, recent trials add important information to results of the comparison and permit strategy-specific analyses, including evaluation of endoscopic evacuation and stereotactic thrombolysis. Methods—: Major scientific databases including but not limited to Pubmed, the CENTRAL (Cochrane Central Register of Controlled Trials), Embase, Web of Science, Scopus, the ICTRP (International Clinical Trials Registry Platform), the Internet Stroke Center, and the CNKI (Chinese National Knowledge Infrastructure) were searched in October of 2017 for randomized controlled trials of MIS treatment of supratentorial spontaneous ICH. The primary outcome was defined as death or dependence at the end of follow-up, and the secondary outcome was defined as death. Results—: The initial search yielded 958 reports, which were reduced to 15 high-quality randomized controlled trials involving 2152 patients. We analyzed odds ratios for MIS overall, endoscopic surgery, and stereotactic thrombolysis compared with conventional treatment, including medical treatment and conventional craniotomy. The odds ratio and CIs of the primary and secondary outcomes were 0.46 (0.36–0.57) and 0.59 (0.45–0.76) for MIS versus conventional treatment; 0.40 (0.25–0.66) and 0.37 (0.20–0.67) for endoscopic surgery versus conventional treatment; 0.47 (0.34–0.65) and 0.76 (0.56–1.04) for stereotactic thrombolysis versus conventional treatment; and 0.44 (0.29–0.67) and 0.56 (0.37–0.84) for MIS versus craniotomy. We also conducted subgroup analyses focusing on time to evacuation for MIS versus conventional treatment and found 0.36 (0.22–0.59) and 0.59 (0.34–1.00) for evacuations performed within 24 hours and 0.49 (0.38–0.63) and 0.57 (0.43–0.76) for evacuations performed within 72 hours. Conclusions—: This meta-analysis demonstrates that select patients with supratentorial ICH benefit from MIS over other treatments. This beneficial effect remains true when analyzing specific techniques and evacuation timing subgroups.

Background Endoscopic intracerebral hemorrhage (ICH) evacuation techniques have gained interest as a potential therapeutic option. However, the instrumentation and techniques employed are still being refined to optimize hemostasis and evacuation efficiency. Objective We describe the application of a specific endoscopic technique in the treatment of ICH called the Stereotactic Intracerebral Hemorrhage Underwater Blood Aspiration (SCUBA) technique. It differs from previously described minimally invasive ICH interventions in that it combines two separate neuroendoscopic strategies in two phases, the first under dry-field conditions and the second using a wet-field strategy. Methods All patients who underwent endoscopic ICH evacuation with the SCUBA technique from December 2015 to September 2017 were included. Results The SCUBA technique was performed in 47 patients. The average evacuation percentage was 88.2% (SD 20.8). Active bleeding identified to derive from a specific source was observed in 23 (48.9%) cases. Active bleeding was addressed with irrigation alone in five cases (10.6%) and required electrocautery in 18 cases (38.3%). Intraoperative bleeding occurred in 3 patients (6.4%) and postoperative bleeding occurred in a single case (2.1%). Conclusions The SCUBA technique provides surgeons with a defined strategy for true endoscopic hematoma evacuation. In particular, the fluid-filled cavity in SCUBA Phase 2 has the potential to provide several advantages over the traditional air-filled strategy, including clear identification and cauterization of bleeding vessels and visualization of residual clot burden. Further investigation is necessary to compare this technique to others that are currently used.
