Patient expectations and decisional regret in the management of ventral hernias.

Introduction: Older adult patients have many factors to contemplate when considering elective ventral hernia repair. In this study, we aimed to understand whether our novel shared decision-making (SDM) aid helped reduce this population's decisional regret when choosing hernia management strategy.

Methods: Patients ≥ 60 years of age presenting for ventral hernia evaluation were randomized to two groups.

Place Coding in the Human Cochlea.

Unlabelled: The cochlea's capacity to decode sound frequencies is enhanced by a unique structural arrangement along its longitudinal axis, a feature termed 'tonotopy' or place coding. Auditory hair cells at the cochlea's base are activated by high-frequency sounds, while those at the apex respond to lower frequencies. Presently, our understanding of tonotopy primarily hinges on electrophysiological, mechanical, and anatomical studies conducted in animals or human cadavers.

Relationship between electrode position and temporal modulation sensitivity in cochlear implant users: Are close electrodes always better?

Temporal modulation sensitivity has been studied extensively for cochlear implant (CI) users due to its strong correlation to speech recognition outcomes. Previous studies reported that temporal modulation detection thresholds (MDTs) vary across the tonotopic axis and attributed this variation to patchy neural survival. However, correlates of neural health identified in animal models depend on electrode position in humans.

The efficacy of goal-directed recommendations in overcoming barriers to elective ventral hernia repair in older adults.

Background: Although ventral hernias are common in older adults and can impair quality of life, multiple barriers exist that preclude ventral hernia repair. The goal of this study was to determine if older adults with ventral hernias achieve surgeon-directed goals to progress to an elective ventral hernia repair.

Methods: Patients ≥60 years evaluated for a ventral hernia in a specialty clinic from January 2018 to August 2021 were retrospectively reviewed.

Is Characteristic Frequency Limiting Real-Time Electrocochleography During Cochlear Implantation?

Objectives: Electrocochleography (ECochG) recordings during cochlear implantation have shown promise in estimating the impact on residual hearing. The purpose of the study was (1) to determine whether a 250-Hz stimulus is superior to 500-Hz in detecting residual hearing decrement and if so; (2) to evaluate whether crossing the 500-Hz tonotopic, characteristic frequency (CF) place partly explains the problems experienced using 500-Hz.

Design: Multifrequency ECochG comprising an alternating, interleaved acoustic complex of 250- and 500-Hz stimuli was used to elicit cochlear microphonics (CMs) during insertion.

Polypharmacy is predictive of postoperative complications in older adults undergoing ventral hernia repair.

Background: Ventral hernias are common in older adults, and may be repaired via a transversus abdominus release (TAR). Older adults undergoing surgery have unique age-related risk factors, including polypharmacy. Polypharmacy is highly prevalent in older adults and is associated with adverse postoperative outcomes.

Perioperative outcomes of the Geriatric Assessment and Medical Preoperative Screening (GrAMPS) program pilot for older hernia patients: does chronological age predict outcomes?

Background: The Geriatric Assessment and Medical Preoperative Screening (GrAMPS) program was an initial attempt to understand and to define the prevalence of age-related risk factors in older patients undergoing elective ventral hernia repair (VHR) or inguinal hernia repair (IHR). Preliminary analysis found significant rates of previously unrecognized objective cognitive dysfunction, multimorbidity and polypharmacy. We now examine whether chronological age as a sole risk factor can predict a patient's perioperative outcomes, and if traditional risk calculators that rely heavily on chronological age can accurately capture a patient's true risk.

Chronological age does not predict postoperative outcomes following transversus abdominis release (TAR).

Background: Transversus abdominis release (TAR) is an effective procedure for the repair of complex ventral hernias. However, TAR is not a low risk operation, particularly in older adults who are disproportionately affected by multiple age-related risk factors. While past studies have suggested that age alone inconsistently predicts patient outcomes, data regarding age's effect on postoperative outcomes and wound complications following a TAR are lacking.

Age-Related Risk Factors in Ventral Hernia Repairs: A Review and Call to Action.

Background: As the population ages, the incidence of ventral hernias in older adults is increasing. Ventral hernia repairs (VHR) should not be considered low risk operations, particularly in older adults who are disproportionately affected by multiple age-related factors that can complicate surgery and adversely affect outcomes. Although age-related risk factors have been well established in other surgical fields, there is currently little data describing their impact on VHR.

Ante- and postmortem tau in autosomal dominant and late-onset Alzheimer's disease.

Antemortem tau positron emission tomography imaging suggests elevated tau pathology in autosomal dominant versus late-onset Alzheimer's disease at equivalent clinical stages, but does not implicate the specific tau pathologies responsible. Here we made stereological measurements of tau neurofibrillary tangles, neuritic plaques, and neuropil threads and found compared to late-onset Alzheimer's disease, autosomal dominant Alzheimer's disease showed even greater tangle and thread burdens. Regional tau burden resembled that observed in tau imaging of a separate cohort at earlier clinical stages.

A Practical Guideline for the Implementation of Shared Decision-making in Complex Ventral Incisional Hernia Repair.

Background: Although obtaining preoperative procedural consent is required to meet legal and ethical obligations, consent is often relegated to a unidirectional conversation between surgeons and patients. In contrast, shared decision-making (SDM) is a collaborative dialog that elicits patient preferences. Despite emerging interest in SDM, there is a paucity of literature on its application to ventral incisional hernia repair (VIHR).

Effects of Electrode Location on Estimates of Neural Health in Humans with Cochlear Implants.

There are a number of psychophysical and electrophysiological measures that are correlated with SGN density in animal models, and these same measures can be performed in humans with cochlear implants (CIs). Thus, these measures are potentially applicable in humans for estimating the condition of the neural population (so called "neural health" or "cochlear health") at individual sites along the electrode array and possibly adjusting the stimulation strategy in the CI sound processor accordingly. Some measures used to estimate neural health in animals have included the electrically evoked compound potential (ECAP), psychophysical detection thresholds, and multipulse integration (MPI).

Comparative Performance and Neuropathologic Validation of the AD8 Dementia Screening Instrument.

Background/objective: The AD8 informant-based screening instrument has been validated with molecular biomarkers of Alzheimer disease (AD) but not with the gold standard of neuropathologic AD. The objective of this study was to validate the AD8 with neuropathologic AD and compare its predictive performance with that of the Mini-Mental State Examination and both participant-derived and informant-derived subjective memory complaint (SMC) regarding the participant.

Methods: This longitudinal cohort study at the Knight Alzheimer Disease Research Center at Washington University included 230 participants, ages 50 to 91 years, who later had a neuropathologic examination.

Procedural Framework to Facilitate Hospital-Based Informed Consent for Dementia Research.

Improving quality and delivery of care for people with Alzheimer disease and related dementias (ADRD) requires a comprehensive research agenda that encompasses the entire care continuum. Logistical and ethical challenges of informed consent for research participation of persons with ADRD include determination of capacity to consent, surrogate consent when capacity to consent is compromised, timely identification of the legally authorized representative (LAR) providing surrogate consent, and balancing residual autonomy with surrogate consent. Short stays; limited access to patients, caregivers, and LARs; and fluctuating influences of acute illness on capacity determination compound these challenges in the acute care setting.

Outcomes of Patients With Syncope and Suspected Dementia.

Objectives: Syncope and near-syncope are common in patients with dementia and a leading cause of emergency department (ED) evaluation and subsequent hospitalization. The objective of this study was to describe the clinical trajectory and short-term outcomes of patients who presented to the ED with syncope or near-syncope and were assessed by their ED provider to have dementia.

Methods: This multisite prospective cohort study included patients 60 years of age or older who presented to the ED with syncope or near-syncope between 2013 and 2016.

Typical Time to Treatment of Patients With Lung Cancer in a Multisite, US-Based Study.

Introduction: The importance of high-quality, timely lung cancer care and the need to have indicators to measure timeliness are increasingly discussed in the United States. This study explored when and why delays occur in lung cancer care and compared timeliness between two states with divergent disease incidence.

Methods: Patients with small-cell or non-small-cell lung cancer were recruited through cancer centers, outpatient clinics, and community approaches, and interviewed over the phone.

Temporal Trends in Postmastectomy Radiation Therapy and Breast Reconstruction Associated With Changes in National Comprehensive Cancer Network Guidelines.

Importance: Evolving data on the effectiveness of postmastectomy radiation therapy (PMRT) have led to changes in National Comprehensive Cancer Network (NCCN) recommendations, counseling clinicians to "strongly consider" PMRT for patients with breast cancer with tumors 5 cm or smaller and 1 to 3 positive nodes; however, anticipation of PMRT may lead to delay or omission of reconstruction, which can have cosmetic, quality-of-life, and complication implications for patients.

Objective: To determine whether revised guidelines have increased PMRT and affected receipt of breast reconstruction. We hypothesized that (1) PMRT rates would increase for women affected by the revised guidelines while remaining stable in other cohorts and (2) receipt of breast reconstruction would decrease in these women while increasing in other groups.

Hospice Enrollment, Local Hospice Utilization Patterns, and Rehospitalization in Medicare Patients.

Background: Rehospitalizations are prevalent and associated with decreased quality of life. Although hospice has been advocated to reduce rehospitalizations, it is not known how area-level hospice utilization patterns affect rehospitalization risk.

Objectives: The study objective was to examine the association between hospice enrollment, local hospice utilization patterns, and 30-day rehospitalization in Medicare patients.

Examining the electro-neural interface of cochlear implant users using psychophysics, CT scans, and speech understanding.

This study examines the relationship between focused-stimulation thresholds, electrode positions, and speech understanding in deaf subjects treated with a cochlear implant (CI). Focused stimulation is more selective than monopolar stimulation, which excites broad regions of the cochlea, so may be more sensitive as a probe of neural survival patterns. Focused thresholds are on average higher and more variable across electrodes than monopolar thresholds.

Changes in auditory perceptions and cortex resulting from hearing recovery after extended congenital unilateral hearing loss.

Monaural hearing induces auditory system reorganization. Imbalanced input also degrades time-intensity cues for sound localization and signal segregation for listening in noise. While there have been studies of bilateral auditory deprivation and later hearing restoration (e.

Hearing thresholds and FMRI of auditory cortex following eighth cranial nerve surgery.

Objective: Determine whether auditory cortex (AC) organization changed following eighth cranial nerve surgery in adults with vestibular-cochlear nerve pathologies. We examined whether hearing thresholds before and after surgery correlated with increased ipsilateral activation of AC from the intact ear.

Study Design: During magnetic resonance imaging sessions before and 3 and 6 months after surgery, subjects listened with the intact ear to noise-like random spectrogram sounds.
