“…The obvious destruction of these areas indicated that the pyramidal tract was apparently destroyed; while the equivocal one was absent. Moreover, the temporal muscle thickness and area[ 5 - 7 , 22 , 24 , 27 , 30 , 46 ] were measured on the head CT at admission as an indicator of sarcopenia[ 40 ] and nutrition[ 14 , 38 ] using the method reported by Katsuki et al .

Background: Reliable prediction models of intracerebral hemorrhage (ICH) outcomes are needed for decision-making of the treatment. Statistically making such prediction models needs a large number of samples and time-consuming statistical analysis. Deep learning (DL), one of the artificial intelligence, is attractive, but there were no reports on DL-based functional outcome prediction models for ICH outcomes after surgery. We herein made a functional outcome prediction model using DLframework, Prediction One (Sony Network Communications Inc., Tokyo, Japan), and compared it to original ICH score, ICH Grading Scale, and FUNC score. Methods: We used 140 consecutive hypertensive ICH patients’ data in our hospital between 2012 and 2019. All patients were surgically treated. Modified Rankin Scale 0–3 at 6 months was defined as a favorable outcome. We randomly divided them into 100 patients training dataset and 40 patients validation dataset. Prediction One made the prediction model using the training dataset with 5-fold cross-validation. We calculated area under the curves (AUCs) regarding the outcome using the DL-based model, ICH score, ICH Grading Scale, and FUNC score. The AUCs were compared. Results: The model made by Prediction One using 64 variables had AUC of 0.997 in the training dataset and that of 0.884 in the validation dataset. These AUCs were superior to those derived from ICH score, ICH Grading Scale, and FUNC score. Conclusion: We easily and quickly made prediction models using Prediction One, even with a small single-center dataset. The accuracy of the DL-based model was superior to those of previous statistically calculated models.

“…Several studies have used the temporal or paravertebral muscle area at cervical vertebra levels (Figure 1). Temporal muscle thickness and area can be measured at the orbital roof level [13][14][15], 5 mm above the level [16,17], or the thickest portion of the temporal muscle [18]. Thickness is measured at the maximum point in the plane, and area is measured manually [16] or automatically [18].…”

“…In another study, temporal muscle thickness was associated with a poor neurological prognosis at three months, defined as Glasgow Outcome Scale scores of 1-3, in neurocritically ill patients, including those with stroke (adjusted odds ratio (OR), 1.27; 95% confidence interval (CI), 1.028-1.576) [21]. The temporal muscle area was evaluated in patients with subarachnoid hemorrhage, and on admission, it was independently associated with modified Rankin Scale scores six months after aneurysm treatment, and the cutoff value of temporal muscle area was <200 mm 2 [16]. Because temporal muscle mass affects physical functions at hospital discharge in patients after aneurysm treatment, it can be a good indication for surgical intervention in aneurysm treatment [17].…”

Muscle mass at admission is important to survive stroke, and stroke-induced sarcopenia is a serious problem because of its poor prognosis. Muscle mass measurement and monitoring are essential for appropriate re-habilitation and nutrition management. Several methods are used to assess skeletal muscle mass in stroke, such as computed tomography (CT), ultrasonography, bioelectrical impedance analysis, dual-energy X-ray absorptiometry, biomarkers, and anthropometrics. In stroke, a head CT is used to estimate muscle mass by measuring the temporal muscle. However, it is mostly retrospectively conducted due to radiation exposure. After stroke, limb muscle atrophy and diaphragm dysfunction are observed using ultrasound. However, ultrasound requires an understanding of the methods and skill. A bioelectrical impedance analysis can be used to assess muscle mass in patients after a stroke unless they have dynamic fluid changes. Dual-energy X-ray absorptiometry is used for follow-up after hospital discharge. Urinary titin N-fragment and serum C-terminal agrin fragment reflect muscle atrophy after stroke. Anthropometrics may be useful with limited resources. We summarized the features of each measurement and proved the recent evidence to properly measure and monitor skeletal muscle mass after stroke.

The surgical efficacy for supratentorial intracerebral hemorrhage (ICH) remains unknown. We compared the advantages of the widely practiced endoscopic hematoma removal under local anesthesia with that of craniotomy under general anesthesia for ICH. We also focused on our novel operative concept of intentional hematoma leaving technique to avoid further damage to the brain. We retrospectively analyzed 134 consecutive patients (66 endoscopies and 68 craniotomies) who were surgically treated for supratentorial ICH. The characteristics of the 134 patients were as follows: The median (interquartile range) age was 73 (61-82) years. The median Glasgow Coma Scale scores at admission, on day 7, and the median modified Rankin Scale (mRS) score at 6 months were 10 (7-13), 13 (10-14), and 4 (3-5) respectively. The statistical comparison revealed there were no differences in GCS score on day seven between the endoscopy 13 (12-14) and craniotomy group 12 (9-14). No differences were observed in mRS scores at 6 months between the endoscopy 4 (2-5) and craniotomy group 4 (3-5). However, the patients treated with our technique tended to have favorable outcomes. Multivariate analysis revealed the operative time was significantly decreased in the endoscopy group compared to the craniotomy group (p < 0.001). Spontaneous intracerebral hemorrhages (ICHs) are responsible for 10%-30% of all strokes and they remain a significant cause of all stroke-related mortality and morbidity 1,2. ICH is a medical emergency with high fatality and disability rates. The median 30-day mortality rate after ICH is approximately 15-50% 3,4 and only 20% of patients regain functional independence within three months after the ictus 5. Surgical hematoma removal and conservative therapy are the main treatments for ICH; however, the role of surgery for most patients with ICH remains controversial. Theoretically, surgical hematoma removal prevents herniation by reducing the intracranial pressure and decreasing the pathophysiological impact of the hematoma on surrounding tissue 2. However, the effectiveness of surgery has been repeatedly evaluated 6,7 and its benefits are still under discussion. The Surgical Trial in Intracerebral Haemorrhage (STICH) indicated that patients with spontaneous supratentorial ICH showed no overall benefit from the early surgery when compared to the initial conservative therapy. However, operative intervention occurred in 24% of patients in the initial conservative treatment group 6. Therefore, the interpretation of these results is complicated. The STICH II trial confirmed that early surgery did not increase the rate of death or disability, 6 months postoperatively, and may have a small but clinically relevant survival advantage for patients with spontaneous superficial ICH without an intraventricular hemorrhage 7. A recent report based primarily on the STICH II trial reported that only patients with a GCS 10-13 or a large ICH were likely to benefit from surgery 8. However, the STICH and STICH II trials did not exhibit an overall comp...
