Replacing alfalfa hay with a novel alfalfa leaf pellet product (ProLEAF MAX) and/or alfalfa stems (ProFiber Plus) in the diet of developing dairy heifers alters dry matter intake, but does not negatively impact growth or development.

Alfalfa is a commonly grown forage in the Intermountain West region of the United States and is often included in the diet of dairy cattle. Alfalfa provides a variety of different nutrients, but the nutrient content of alfalfa varies depending on factors such as the soil, region, cutting, and climate. However, alfalfa leaves tend to have less variation in their nutrient content than alfalfa stems.

UK biobank: Enhanced assessment of the epidemiology and long-term impact of coronavirus disease-2019.

UK Biobank is an intensively characterised prospective cohort of 500,000 adults aged 40-69 years when recruited between 2006 and 2010. The study was established to enable researchers worldwide to undertake health-related research in the public interest. The existence of such a large, detailed prospective cohort with a high degree of participant engagement enabled its rapid repurposing for coronavirus disease-2019 (COVID-19) research.

Persistence of SARS-CoV-2 antibodies over 18 months following infection: UK Biobank COVID-19 Serology Study.

Background: Little is known about the persistence of antibodies after the first year following SARS-CoV-2 infection. We aimed to determine the proportion of individuals that maintain detectable levels of SARS-CoV-2 antibodies over an 18-month period following infection.

Methods: Population-based prospective study of 20 000 UK Biobank participants and their adult relatives recruited in May 2020.

Long-term cognition and speech recognition outcomes after cochlear implantation in the elderly.

Objective: The purpose of this study is to investigate how cognition, as measured using the Self-Administered Gerocognitive Examination Test (SAGE), and age affect speech recognition scores in older adults (age > 65) at one year and two years after cochlear implantation.

Study Design: This is a prospective study.

Setting: This study was conducted at a single institution.

Social determinants of ethnic disparities in SARS-CoV-2 infection: UK Biobank SARS-CoV-2 Serology Study.

Background: The social determinants of ethnic disparities in risk of SARS-CoV-2 infection during the first wave of the pandemic in the UK remain unclear.

Methods: In May 2020, a total of 20 195 adults were recruited from the general population into the UK Biobank SARS-CoV-2 Serology Study. Between mid-May and mid-November 2020, participants provided monthly blood samples.

Clinical performance, audiological outcomes, and quality of life of the Cochlear Osia ® system.

Objective: The Cochlear Osseointegrated Steady-State Implant Bone Anchored Hearing Device (Osia) is a surgically implanted titanium apparatus that utilizes a piezoelectric actuator under the skin to address conductive and mixed hearing loss as well as single-sided deafness. The purpose of this study is to examine the clinical, audiologic, and quality-of-life outcomes in patients who underwent Osia implantation.

Methods: This is a retrospective study analyzing 30 adult patients (age 27-86) with conductive healing loss (CHL), mixed hearing loss (MHL), or single-sided deafness (SSD) who were implanted with the Osia device from January 2020 to April 2023 at a single institution by the senior author.

The effects of organic grass and grass-birdsfoot trefoil pastures on Jersey heifer development: Heifer growth, performance, and economic impact.

Dairy heifers developed in certified organic programs, especially those utilizing pasture-based management schemes, have lower rates of gain than heifers raised in nonorganic confinement production systems in temperate climates, such as in the Intermountain West region of the United States. This study investigates the effects that different forages in a rotational grazing system have on development of organically raised Jersey heifers. Over 3 years, 210 yearling Jersey heifers were randomly assigned to one of 9 treatments, including a conventional confinement control where animals were fed a total mixed ration or one of 8 pasture treatments: Cache Meadow bromegrass (Bromus riparius Rehmann), QuickDraw orchard grass (Dactylis glomerata L.

Effects of feeding a novel alfalfa leaf pellet product (ProLEAF MAX) and alfalfa stems (ProFiber Plus) on performance in the feedlot and carcass quality of beef steers.

Alfalfa is often included in the diets of beef animals; however, the nutrient content of alfalfa is variable depending on the region in which it is grown, climate, soil, and many other factors. The leaf portion of alfalfa has a less variable nutrient composition than the stem portion of the plant. The variability that is present in the alfalfa plant can make the development of total mixed rations of consistent nutrient content difficult.

Transoral robotic submandibular gland transposition to reconstruct radical tonsillar resection defects.

Significant dysphagia, pain, and risk of bleeding occur after transoral robotic surgery (TORS) radical tonsillectomy. We present a novel surgical technique utilizing robotically assisted submandibular gland transposition (SMGT) to reconstruct the radical tonsillar defect. A 48-year-old male with p16+ tonsillar squamous cell carcinoma underwent deep TORS radical tonsillectomy, contralateral tonsillectomy, ipsilateral neck dissection, and TORS-assisted reconstruction of the radical defect with ipsilateral SMGT.

Middle Ear Salivary Choristoma: A Rare Case Report and Update on Congenital Associations, Facial Nerve Involvement, and Treatment Strategies.

Salivary gland choristoma is an extremely rare middle ear mass and is hypothesized to be caused by second branchial arch developmental anomalies. We present a 14-year-old girl with Dandy-Walker syndrome and conductive hearing loss. Middle ear exploration revealed a large middle ear mass with absent incus and stapes and displaced facial nerve.

Sound levels with aural suctioning: Effects of suction size, canal moisture, and distance from the eardrum.

Objective: To determine sound levels resulting from aural suctioning of the external auditory canal.

Methods: Unweighted decibels (dB) and A-weighted decibels (dBA) sound pressure level measurements were recorded using a retrotympanic microphone in cadaveric human temporal bones. Sound measurements were made with common otologic suctions, size 3, 5, and 7 French, within the external ear canal at the tympanic membrane, 5, and 10 mm from the tympanic membrane in the dry condition.

Posttraumatic Cranial Suture Diastasis in Pediatric Temporal Bone Fractures.

Objective: Only a handful of case reports exist describing posttraumatic sutural diastasis in the calvarium and none report concurrent temporal bone involvement. We aim to describe diastasis along the temporal bone suture lines in the setting of temporal bone trauma and to identify clinical sequelae.

Study Design: Retrospective case review.
