The analysis of cell-free DNA (cfDNA) from plasma offers great promise for the earlier detection of cancer. At present, changes in DNA sequence, methylation, or copy number are the most sensitive ways to detect the presence of cancer. To further increase the sensitivity of such assays with limited amounts of sample, it would be useful to be able to evaluate the same template molecules for all these changes. Here, we report an approach, called MethylSaferSeqS, that achieves this goal, and can be applied to any standard library preparation method suitable for massively parallel sequencing...

BACKGROUND: In 2022, Mpox (MPX) has become clinically relevant as otolaryngologists are evaluating this exotic disease process due to its many otolaryngologic manifestations. AIMS/OBJECTIVE: To characterize our cohort of otolaryngology-relevant MPX confirmed cases. MATERIALS AND METHODS: A descriptive case series was performed via retrospective review. Adult patients who underwent inpatient or emergency department otolaryngology consultation at an Emory University-affiliated tertiary care level hospital for MPX were included...

BACKGROUND: Dermatologists perform most interpolated flaps after skin cancer resection. Prospective, multicenter data on complications after interpolated flap repair in this setting are limited. OBJECTIVE: To determine the rate of physician-reported complications after interpolated flap repair of the nose. METHODS: Multicenter, prospective cohort study of 169 patients undergoing 2-stage interpolated flap repair of post-Mohs nasal defects. Frequency of bleeding, infection, dehiscence, necrosis, hospitalization, and death in the 30 days after flap placement and flap takedown are reported...

Different materials and techniques have been proposed for surgical repair of spontaneous middle cranial fossa (MCF) defects. However, conclusive evidence supporting their selection and impact on clinical outcomes is lacking. The study aims to conduct a systematic review and meta-analysis on materials and techniques employed to repair MCF defects and evaluate complications and rates of recurrent cerebrospinal fluid (CSF) leaks. A PRISMA-guided systematic review and meta-analysis were performed using MESH terms and specific keywords including studies published before May 2022...

There are many articles in the literature on periorbital reconstruction after Mohs micrographic surgery (MMS) or surgical excision, however, the literature lacks a comprehensive systematic review of these reports. We performed a systematic review of published data on periorbital defect reconstruction to identify trends in the literature. A comprehensive search of eight databases was performed. To be included in the study, articles had to be published in English between 2005 and 2020 and contain repair data for MMS or excision defects in the periorbital region...

The therapeutic applications of antibodies are manifold and the emergence of SARS-CoV-2 provides a cogent example of the value of rapidly identifying biologically active antibodies. We describe an approach called SLISY (Sequencing-Linked ImmunoSorbent assaY) that in a single experiment can assess the binding specificity of millions of clones, be applied to any screen that links DNA sequence to a potential binding moiety, and requires only a single round of biopanning. We demonstrate this approach using an scFv library applied to cellular and protein targets to identify specific or broadly reacting antibodies...

Glomus tympanicum are benign tumors of vascular origin, arising from the neural crest cells and located on promontory. The treatment of choice is surgical excision of the lesion. Traditionally, it is performed under microscopic observation. With the introduction of endoscopes in the field of ear surgeries, an endoscopic approach has also evolved. Herein, we present case reports of three patients diagnosed with glomus tympanicum tumors who were operated on using an endoscopic approach. A review of the literature is also performed...

Managed turfgrass is a common component of urban landscapes that is expanding under current land use trends. Previous studies have reported high rates of soil carbon sequestration in turfgrass, but no systematic review has summarized these rates nor evaluated how they change as turfgrass ages. Here we conducted a meta-analysis of soil carbon sequestration rates from 63 studies globally, comprised mostly of C3 grass species in the U.S., including 24 chronosequence studies that evaluated carbon changes over 75 years or longer...

Thoracic and cervical paraganglioma (PGL) is a rare neuroendocrine tumor arising from chromaffin cells of the neural crest progenitors located outside the adrenal gland. We describe our current protocol as a multidisciplinary team for the management of cervical and thoracic PGL. Surgery is generally considered the treatment of choice as it offers the best chance for cure. For resection of thoracic PGL, video-assisted thoracoscopic surgery (VATS) is the main surgical approach, while open thoracotomy is preferred in case of tumor >6cm, lacking confirmation of a plane of separation with adjacent structures, or with technical difficulties during VATS...

The endoscopic endonasal approach (EEA) has proven to be a valuable tool to access the petrous apex (PA).1 Although lesions located medial to the PA can be easily accessed through an EEA with minimal risk to the internal carotid artery (ICA), more laterally seated lesions represent a surgical challenge. The contralateral transmaxillary approach is an effective extension of the normal EEA to the PA, allowing a more lateral trajectory and thereby reducing the risks connected to paraclival ICA manipulation.2-4 This is a 47-year-old female presenting with tinnitus, hearing loss, and right facial twitching...

Plants are key components of the terrestrial ecosystem carbon cycle. Atmospheric CO2 is assimilated through photosynthesis and stored in plant biomass and in the soil. The use of turfgrass is expanding due to the increasing human population and urbanization. In this review, we summarize recent carbon sequestration research in turfgrass and compare turfgrass systems to other plant systems. The soil organic carbon (SOC) stored in turfgrass systems is comparable to that in other natural and agricultural systems...

PD-L1 testing guides therapeutic decision-making for head and neck squamous cell carcinoma (HNSCC). We sought to understand whether chemoradiation therapy (CRT) influences the PD-L1 combined positive score (CPS) and other biomarkers of response to immunotherapy. PD-L1 expression was assessed using immunohistochemistry, and bulk RNA sequencing was performed on 146 HNSCC patients (65 primary sites, 50 paired local recurrences, and 31 paired regional recurrences). PD-L1 was scored using the CPS of ≥1, ≥20, and ≥50...

BACKGROUND: Recent studies highlighted how exoscopes may be employed to approach the lateral skull base. The use of exoscope-assisted procedures to repair middle cranial fossa (MCF) defects has not been fully explored. The surgical microscope in the same circumstances has been associated with relevant limitations, such as its physical obstruction, among others. The aim of this study was to present a proof of concept of exoscope-assisted surgery for MCF defects. METHODS: A detailed step-by-step MCF approach was performed on 2 alcohol-preserved, latex-injected cadaveric specimens under exoscopic magnification...

Numerous reconstructive techniques for nasal defects following skin cancer removal have been described; however, the literature lacks a comprehensive systematic review. Our objective was to systematically review nasal reconstruction methods after tumor removal, correlate the use of specific techniques to the nasal subunits involved, assess the quality of the available evidence, and set the stage for future research on this topic. Eight databases were searched for studies published in English from January 2004 to December 2018 containing repair data for nasal defects following Mohs or excision for four or more subjects...

Transparency is increasingly promoted to instill trust in nonrandomized studies using real-world data. Graphics and data visualizations support transparency by aiding communication and understanding, and can inform study design and analysis decisions. However, other than graphical representation of a study design and flow diagrams (e.g., a Consolidated Standards of Reporting Trials [CONSORT] like diagram), specific standards on how to maximize validity and transparency with visualization are needed. This paper provides guidance on how to use visualizations throughout the life cycle of a pharmacoepidemiology study - from initial study design to final report - to facilitate rationalized and transparent decision-making about study design and implementation, and clear communication of study findings...

Repair of auricular defects following tumor removal can be challenging. Many techniques have been described, but the literature lacks a comprehensive review of these methods. To perform a systematic review to compile and describe methods of reconstruction for post-surgical defects on the ears, eight databases were searched using terms related to ear anatomy, Mohs and excisions, and repair methods. Articles were eligible for inclusion if they contained repair data for ear defects following Mohs or excision for at least 4 subjects and were published in English between 2004 and 2019...

Objective: Among patients undergoing two-stage interpolated flap repair of nasal defects, nasal function, and appearance before surgery and at 16 weeks after flap takedown were compared using the Nasal Appearance and Function Evaluation Questionnaire (NAFEQ). Design: Multicenter prospective cohort study. Methods: Adult patients with a nasal skin cancer anticipated to require two-stage interpolation flap repair completed the NAFEQ before surgery, at 1 week after flap placement, 4 weeks after flap takedown, and 16 weeks after flap takedown...

BACKGROUND: Agitation management is a principal challenge on inpatient psychiatric units. Overreliance on common prescribing strategies of pro re nata (PRN) medication administration is problematic, given the tendencies to have overlapping or unclear indications. OBJECTIVE: Piloted project to determine whether a standardized protocol for agitation intervention may reduce PRN medication administration. METHODS: The Birmingham Agitation Management (BAM) interdisciplinary team uniquely connected the Brøset Violence Checklist (BVC) for assessment of agitation severity to a standardized PRN medication order set...
