Saturation profiling of drug-resistant genetic variants using prime editing.

Methods to characterize the functional effects of genetic variants of uncertain significance (VUSs) have been limited by incomplete coverage of the mutational space. In clinical oncology, drug resistance arising from VUSs can prevent optimal treatment. Here we introduce PEER-seq, a high-throughput method based on prime editing that can evaluate the functional effects of single-nucleotide variants (SNVs).

The Anterolateral Approach, Revisited for Benign Jugular Foramen Tumors With Predominant Extracranial Extension: Microsurgical Anatomy and Case Series (SevEN-012).

Background And Objectives: The anterolateral approach (ALA) enables access to the mid and lower clivus, jugular foramen (JF), craniocervical junction, and cervical spine with added anterior and lateral exposure than the extreme lateral and endoscopic endonasal approach, respectively. We describe the microsurgical anatomy of ALA with cadaveric specimens and report our clinical experience for benign JF tumors with predominant extracranial extension.

Methods: A stepwise and detailed microsurgical neurovascular anatomy of ALA was explored with cadaveric specimens.

Regrowth factors of WHO grade I skull base meningiomas following incomplete resection.

Objective: The role of adjuvant radiation therapy following incomplete resection of WHO grade I skull base meningiomas (SBMs) is controversial, and little is known regarding the behavior of residual tumors. The authors investigated the factors that influence regrowth of residual WHO grade I SBMs following incomplete resection.

Methods: From 2005 to 2019, a total of 710 patients underwent surgery for newly diagnosed WHO grade I SBMs.

The effect of hematoma evacuation with decompressive craniectomy on clinical outcomes in patients with parenchymal hematoma type 2 of hemorrhagic transformation after middle cerebral artery infarction.

Objectives: The purpose of this study was to investigate the feasibility of hematoma evacuation (HE) with decompressive craniectomy (DC) and to evaluate whether HE with DC is associated with improvement of clinical outcomes in patients with parenchymal hematoma type 2 (PH2) after middle cerebral artery (MCA) infarction.

Methods: Between March 2007 and August 2020, 73 patients with PH2 after MCA infarction underwent DC. The HE group (n = 28) consisted of subjects who underwent HE with DC and the non-HE group (n = 45) consisted of subjects who underwent only DC without HE.

The behavior of residual tumors following incomplete surgical resection for vestibular schwannomas.

The management of vestibular schwannoma (VS) with residual tumor following incomplete resection remains controversial and little is known regarding postoperative tumor volume changes. The behavior of residual tumors was analyzed for 111 patients who underwent surgery for newly diagnosed VS between September 2006 and July 2017. The postoperative tumor volume changes were assessed during a mean follow-up of 69 months (range 36-147 months).

Apparent diffusion coefficient as a prognostic factor in clival chordoma.

Clival chordoma is a rare disease with high recurrence rates even after a combination of surgical resection and radiotherapy. Apparent diffusion coefficient (ADC) has been used to evaluate aggressive features of chordoma, but its utility for clival chordoma has not been explored specifically. In this study, the utility of preoperative ADC values was analyzed for predicting tumor progression and recurrence in patients with clival chordoma.

Abdominal compartment syndrome following posterior lumbar fusion in a patient with previous abdominal surgery.

Introduction: Perioperative complications associated with spinal fusion have been investigated steadily to reduce morbidity and mortality. Although there are several reports reviewing abdominal complications occurring with anterior spinal fusion, complications related to posterior spinal fusion (PSF) are rare. However, abdominal compartment syndrome (ACS) after PSF could be the most fatal and unpredictable complication in spinal surgery.

LSTM-Guided Coaching Assistant for Table Tennis Practice.

Recently, wearable devices have become a prominent health care application domain by incorporating a growing number of sensors and adopting smart machine learning technologies. One closely related topic is the strategy of combining the wearable device technology with skill assessment, which can be used in wearable device apps for coaching and/or personal training. Particularly pertinent to skill assessment based on high-dimensional time series data from wearable sensors is classifying whether a player is an expert or a beginner, which skills the player is exercising, and extracting some low-dimensional representations useful for coaching.
