Reexamining predictors of trial outcomes in New York State's sex offender civil management process.

OBJECTIVE: In 2007, New York enacted the Sex Offender Management and Treatment Act, empowering the state to civilly manage individuals who have committed sexual offenses (respondents) and are deemed to have a mental abnormality (MA) that predisposes them to sexually recidivate after serving their criminal sentences. We sought to replicate and extend a previous study (Lu et al., 2015) to identify factors predicting legal decisions. HYPOTHESES: We predicted, on the basis of previous research, that clinical information (e.g., diagnosis) as well as empirically supported risk factors (e.g., sexual deviance) would predict trial outcomes. METHOD: We analyzed multiple pieces of demographic, criminogenic, and clinical data on three nested subsamples of respondents on the basis of the legal process: MA consent (n = 713), MA trial (n = 316), and disposition hearing (n = 643). The binary outcomes of interest were as follows: For the MA consent subsample, it was whether the respondent waived their MA trial; for the MA trial subsample, it was whether the respondent was found at trial to have an MA; and for the disposition hearing, it was whether the respondent was ordered to inpatient or outpatient civil management. RESULTS: The strongest predictor of waiving the trial was geographic location; respondents outside New York City and Long Island were more likely to waive their trials (ORs = 2.38-3.37). The strongest predictors of MA trial and disposition hearing outcomes were Diagnostic and Statistical Manual of Mental Disorders diagnoses; pedophilia (ORs = 4.05-7.22) and sexual sadism (ORs = 2.68-7.03) diagnoses increased the likelihood of an MA finding and confinement order. CONCLUSIONS: Judges and juries give significant weight to clinical information, particularly pedophilia diagnoses, when making civil management legal decisions.

Cochlear Fibrosis after Vestibular Schwannoma Resection via the Middle Cranial Fossa Approach.

OBJECTIVE: The aim of this study was to determine the incidence of cochlear fibrosis after vestibular schwannoma (VS) resection via middle cranial fossa (MCF) approach. DESIGN: A retrospective case review was conducted. SETTING: The review was conducted in a tertiary care academic medical center. PARTICIPANTS: Patients who (1) underwent resection of VS via MCF approach between 2013 and 2018, (2) had complete pre- and post-audiometric testing, and (3) had clinical follow-up with magnetic resonance imaging (MRI) for at least 1 year after surgery were included. MAIN OUTCOME MEASURE(S): The main outcome of this study was cochlear fibrosis as assessed by MRI 1 year after surgery. RESULTS: Fifty-one patients underwent VS resection via MCF technique during the study period. Of 31 patients with AAO-HNS class A or B preoperative hearing ability, 18 (58.0%) maintained class A, B, or C hearing postoperatively. Of 16 patients who lost hearing and had MRI 1 year after surgery, 11 (61.1%) had MRI evidence of fibrosis in at least some portion of the labyrinth and 4 (22.2%) showed evidence of cochlear fibrosis. Of 16 patients with preserved hearing and MRI 1 year after surgery, 4 (25%) had fibrosis in some portion of the labyrinth, with no fibrosis in the cochlea. CONCLUSIONS: In patients who lose hearing during VS resection with the MCF approach, there is usually MRI evidence of fibrosis in the labyrinth 1 year after surgery. However, there is also, but less commonly, fibrosis involving the cochlea. It is unclear if this will affect the ability to insert a cochlear implant electrode array.

Multi-Disciplinary Skull Base Conference and its Effects on Patient Management.

OBJECTIVE: Examine the effects of a multi-disciplinary skull base conference (MDSBC) on the management of patients seen for skull base pathology in a neurotology clinic. METHODS: Retrospective case review of patients who were seen in a neurotology clinic at a tertiary academic medical center for pathology of the lateral skull base and were discussed at an MDSBC between July 2019 and February 2020. Patient characteristics, nature of the skull base pathology, and pre- and post-MDSBC plan of care was categorized. RESULTS: A total of 82 patients with pathology of the lateral skull base were discussed at a MDSBC during an 8-month study period. About 54 (65.9%) had a mass in the internal auditory canal and/or cerebellopontine angle while 28 (34.1%) had other pathology of the lateral skull base. Forty-nine (59.8%) were new patients and 33 (40.2%) were established. The management plan changed in 11 (13.4%, 7.4-22.6 95% CI) patients as a result of the skull base conference discussion. The planned management changed from some form of treatment to observation in 4 patients, and changed from observation to some form of treatment in 4 patients. For 3 patients who underwent surgery, the planned approach was altered. CONCLUSIONS: For a significant proportion of patients with pathology of the lateral skull base, the management plan changed as a result of discussion at an MDSBC. Although participants of a MDSBC would agree of its importance, it is unclear how an MDSBC affects patient outcomes.

Comprehensive collagen crosslinking comparison of microfluidic wet-extruded microfibers for bioactive surgical suture development.

Collagen microfiber-based constructs have garnered considerable attention for ligament, tendon, and other soft tissue repairs, yet with limited clinical translation due to strength, biocompatibility, scalable manufacturing, and other challenges. Crosslinking collagen fibers improves mechanical properties; however, questions remain regarding optimal crosslinking chemistries, biocompatibility, biodegradation, long-term stability, and potential for biotextile assemble at scale, limiting their clinical usefulness. Here, we assessed over 50 different crosslinking chemistries on microfluidic wet-extruded collagen microfibers made with clinically relevant collagen to optimize collagen fibers as a biotextile yarn for suture or other medical device manufacture. The endogenous collagen crosslinker, glyoxal, provides extraordinary fiber ultimate tensile strength near 300MPa, and Young's modulus of over 3GPa while retaining 50% of the initial load-bearing capacity through 6 months as hydrated. Glyoxal crosslinked collagen fibers further proved cytocompatible and biocompatible per ISO 10993-based testing, and further elicits a predominantly M2 macrophage response. Remarkably these strong collagen fibers are amenable to industrial braiding to form strong collagen fiber sutures. Collagen microfluidic wet extrusion with glyoxal crosslinking thus progress bioengineered, strong, and stable collagen microfibers significantly towards clinical use for potentially promoting efficient healing compared to existing suture materials. STATEMENT OF SIGNIFICANCE: Towards improving clinical outcomes for over 1 million ligament and tendon surgeries performed annually, we report an advanced microfluidic extrusion process for type I collagen microfiber manufacturing for biological suture and other biotextile manufacturing. This manuscript reports the most extensive wet-extruded collagen fiber crosslinking compendium published to date, providing a tremendous recourse to the field. Collagen fibers made with clinical-grade collagen and crosslinked with glyoxal, exhibit tensile strength and stability that surpasses all prior reports. This is the first report demonstrating that glyoxal, a native tissue crosslinker, has the extraordinary ability to produce strong, cytocompatible, and biocompatible collagen microfibers. These collagen microfibers are ideal for advanced research and clinical use as surgical suture or other tissue-engineered medical products for sports medicine, orthopedics, and other surgical indications.

Biomanufacturing organized collagen-based microfibers as a Tissue ENgineered Device (TEND) for tendon regeneration.

Approximately 800, 000 surgical repairs are performed annually in the U.S. for debilitating injuries to ligaments and tendons of the foot, ankle, knee, wrist, elbow and shoulder, presenting a significant healthcare burden. To overcome current treatment shortcomings and advance the treatment of tendon and ligament injuries, we have developed a novel electrospun Tissue ENgineered Device (TEND), comprised of type I collagen and poly(D,L-lactide) (PDLLA) solubilized in a benign solvent, dimethyl sulfoxide (DMSO). TEND fiber alignment, diameter and porosity were engineered to enhance cell infiltration leading to promote tissue integration and functional remodeling while providing biomechanical stability. TEND rapidly adsorbs blood and platelet-rich-plasma (PRP), and gradually releases growth factors over two weeks. TEND further supported cellular alignment and upregulation of tenogenic genes from clinically relevant human stem cells within three days of culture. TEND implanted in a rabbit Achilles tendon injury model showed new in situ tissue generation, maturation, and remodeling of dense, regularly oriented connective tissue in vivo. In all, TEND's organized microfibers, biological fluid and cell compatibility, strength and biocompatiblility make significant progress towards clinically translating electrospun collagen-based medical devices for improving the clinical outcomes of tendon injuries.

Real-World Compliance With Follow-up in 2,554 Cochlear Implant Recipients: An Analysis of the HERMES Database.

BACKGROUND: Traditional paradigms of care recommend close audiology follow-up and regular speech perception outcomes assessment indefinitely for cochlear implant (CI) recipients after device activation. However, there is scant published data on actual compliance with this paradigm in clinical practice. METHODS: A multi-center cochlear implant database was queried to identify follow-up rates after cochlear implantation. Follow-up rates where speech perception outcomes assessment occurred at 1-, 3-, 6-, 12-, 18-, and 24-months post-activation were determined by tabulating observed follow-up divided by expected follow-up (O/E ratio) expressed as a percentage. To determine all-cause audiology follow-up rates (with or without testing speech perception outcomes assessment), the database patients from two participating centers (one private practice and one academic center) were similarly analyzed using electronic health record (EHR) data to calculate O/E rates where audiology follow-up occurred for any reason. RESULTS: O/E follow-up rates where speech perception outcomes assessment occurred was 42, 40, 31, 29, 5, and 22% for 1-, 3-, 6-, 12-, 18-, and 24-months post-activation, respectively (n = 2,554). All-cause audiology follow-up rates (with or without speech perception outcomes assessment) using EHR-confirmed data from two individual centers were 97, 94, 81, 66, 41, and 35% at 1-, 3-, 6-, 12-, 18-, and 24-months post-activation visits, respectively (n = 118). CONCLUSIONS: Compliance with audiology follow-up and speech perception outcomes assessment is generally low and decreases significantly as time post-activation increases. Future paradigms of care for CI should be designed recognizing the significant attrition that occurs with CI follow-up.

Early Experience With Telemedicine in Patients Undergoing Otologic/Neurotologic Procedures.

OBJECTIVE: Compare outcomes for patients who were seen via telemedicine visits after otology/neurotology surgical procedures with those who were seen in traditional office visits. STUDY DESIGN: Retrospective case review. SETTING: Tertiary care academic medical center. PATIENTS: Inclusion criteria were patients who underwent otologic/neurotologic surgery and were seen in at least one telemedicine visit for postoperative care. INTERVENTION (S): Telemedicine visit for postoperative care. MAIN OUTCOME MEASURE (S): Comparison of the number of patient calls, unplanned visits, and delayed complications between telemedicine patients and controls matched for age, procedure, and American Society of Anesthesiologists (ASA) status. RESULTS: Eighteen patients were seen in telemedicine visits postoperatively after the following otologic/neurotologic surgical procedures: cochlear implant surgery (10), vestibular schwannoma resection (4), combined middle fossa and transmastoid cerebrospinal fluid (CSF) leak repair (2), middle fossa repair of superior canal dehiscence (1), and stapedectomy (1). All telehealth visits were for the second postoperative visit. The mean number of patient calls after surgery was 2.3 for the telemedicine group and 1.9 for matched controls which was not a statistically significant difference (p = 0.466). Both groups each had two patients who went to the emergency room, with one in each group being admitted. There was one delayed complication in the control group. CONCLUSION: Our preliminary experience suggests telemedicine may be used safely in caring for patients after otologic/neurotologic surgery, though it may be associated with more patient phone calls. Further study and experience, including assessing patient satisfaction, will clarify the future role of telemedicine in otology and neurotology.

Pneumatospinning of collagen microfibers from benign solvents.

INTRODUCTION: Current collagen fiber manufacturing methods for biomedical applications, such as electrospinning and extrusion, have had limited success in clinical translation, partially due to scalability, cost, and complexity challenges. Here we explore an alternative, simplified and scalable collagen fiber formation method, termed 'pneumatospinning,' to generate submicron collagen fibers from benign solvents. METHODS AND RESULTS: Clinical grade type I atelocollagen from calf corium was electrospun or pneumatospun as sheets of aligned and isotropic fibrous scaffolds. Following crosslinking with genipin, the collagen scaffolds were stable in media for over a month. Pneumatospun collagen samples were characterized using Fourier-transform infrared spectroscopy, circular dichroism, mechanical testing, and scanning electron microscopy showed consistent fiber size and no deleterious chemical changes to the collagen were detected. Pneumatospun collagen had significantly higher tensile strength relative to electrospun collagen, with both processed from acetic acid. Stem cells cultured on pneumatospun collagen showed robust cell attachment and high cytocompatibility. Using DMSO as a solvent, collagen was further co-pneumatospun with poly(d,l-lactide) to produce a blended microfibrous biomaterial. CONCLUSIONS: Collagen microfibers are shown for the first time to be formed using pneumatospinning, which can be collected as anisotropic or isotropic fibrous grafts. Pneumatospun collagen can be made with higher output, lower cost and less complexity relative to electrospinning. As a robust and rapid method of collagen microfiber synthesis, this manufacturing method has many applications in medical device manufacturing, including those benefiting from anisotropic microstructures, such as ligament, tendon and nerve repair, or for applying microfibrous collagen-based coatings to other materials.

Demineralized bone matrix fibers formable as general and custom 3D printed mold-based implants for promoting bone regeneration.

INTRODUCTION: Bone repair frequently requires time-consuming implant construction, particularly when using un-formed implants with poor handling properties. We therefore developed osteoinductive, micro-fibrous surface patterned demineralized bone matrix (DBM) fibers for engineering both defect-matched and general three-dimensional implants. METHODS AND RESULTS: Implant molds were filled with demineralized human cortical bone fibers there were compressed and lyophilized, forming mechanically strong shaped DBM scaffolds. Enzyme linked immunosorbent assays and mass spectrometry confirmed that DBM fibers contained abundant osteogenic growth factors (bone morphogenetic proteins, insulin-like growth factor-I) and extracellular matrix proteins. Mercury porosimetry and mechanical testing showed interconnected pores within the mechanically stable, custom DBM fiber scaffolds. Mesenchymal stem cells readily attached to the DBM and showed increasing metabolic activity over time. DBM fibers further increased alkaline phosphatase activity in C2C12 cells. In vivo, DBM implants elicited osteoinductive potential in a mouse muscle pouch, and also promoted spine fusion in a rat arthrodesis model. SIGNIFICANCE: DBM fibers can be engineered into custom-shaped, osteoinductive and osteoconductive implants with potential for repairing osseous defects with precise fitment, potentially reducing operating time. By providing pre-formed and custom implants, this regenerative allograft may improve patient outcomes following surgical bone repair, while further advancing personalized orthopedic and craniomaxillofacial medicine using three-dimensional-printed tissue molds.

Characterization of the mechanical properties of bovine cortical bone treated with a novel tissue sterilization process.

Over the past decade chemical processing and engineering of musculoskeletal tissue (tendon and bone) has improved dramatically. The use of bone allograft and xenograft in reconstructive orthopedic and maxillofacial surgeries is increasing, yet severe complications can occur if the material is contaminated in any way. A novel tissue sterilization process, BioCleanse®, has been developed to clean and sterilize musculoskeletal tissue for implantation. The present study was designed to determine the effect of this novel cleaning process on the biomechanical properties of bovine cortical bone prior to implantation. The mechanical properties of treated bovine bone material were compared to human samples with respect to failure under compression, shear and three-point bending. The data demonstrate that bovine bone treated with the novel sterilization procedure has favorable biomechanical properties compared to that of human bone treated in a similar fashion.
