Safety and Efficacy of Deutetrabenazine at High versus Lower Daily Dosages in the ARC-HD Study to Treat Chorea in Huntington Disease.

Background: Huntington disease (HD) is a progressive neurodegenerative disease that causes psychiatric and neurological symptoms, including involuntary and irregular muscle movements (chorea). Chorea can disrupt activities of daily living, pose safety issues, and may lead to social withdrawal. The vesicular monoamine transporter 2 inhibitors tetrabenazine, deutetrabenazine, and valbenazine are approved treatments that can reduce chorea.

A novel technique to identify and thermally ablate the greater occipital nerve for patients with occipital neuralgia: a retrospective study with cadaveric and validation.

Background: This manuscript presents the challenges of treating various forms of headaches and the potential of interventional techniques targeting the greater occipital nerve (GON) to alleviate the burden on patients. Occipital neuralgia, characterized by stabbing or shooting pain in the base of the skull, is often associated with primary, cervicogenic, or migraine headaches. While occipital nerve blocks offer temporary relief, durable treatment options are limited.

Relationships of B12 and Homocysteine with Outcomes in the SURE-PD, SURE-PD3, and STEADY-PDIII Trials.

Background: DATATOP was a study of early Parkinson's disease (PD) conducted in the 1980 s, before mandatory folic acid fortification in the United States. Our analysis of its baseline serum samples revealed a geometric mean vitamin B12 of 369 pg/mL and homocysteine (tHcy) of 9.5μmol/l.

Cemented Constrained Liners Used as an Articulating Hip Spacer for the Treatment of Chronic Prosthetic Joint Infection.

Background: Two-stage exchange arthroplasty remains the gold standard for treating chronic hip periprosthetic joint infections. However, controversy remains regarding the optimal spacer type, particularly among patients with increased dislocation risk. This study reports on the outcomes of articulating hip spacers utilizing a single constrained-liner design.

Fracture of the Proximal Body of a Modern Cementless Modular Fluted Tapered Stem.

Previous reports have described failures of modular fluted tapered femoral stems secondary to fatigue failure at the modular junction. However, the present study is the first reported case of modular fluted tapered femoral component failure involving atraumatic fracture of the proximal body following revision total hip arthroplasty. The failure occurred in a 52-year-old female with a history of postmenopausal osteoporosis on bisphosphonates who sustained an atraumatic fracture of the proximal body of a modular revision femoral stem.

Microglia are dispensable for experience-dependent refinement of mouse visual circuitry.

To test the hypothesized crucial role of microglia in the developmental refinement of neural circuitry, we depleted microglia from mice of both sexes with PLX5622 and examined the experience-dependent maturation of visual circuitry and function. We assessed retinal function, receptive field tuning of visual cortex neurons, acuity and experience-dependent plasticity. None of these measurements detectibly differed in the absence of microglia, challenging the role of microglia in sculpting neural circuits.

Cognitive Symptoms in Cross-Sectional Parkinson Disease Cohort Evaluated by Human-in-the-Loop Machine Learning and Natural Language Processing.

Background And Objectives: Cognitive impairment is experienced by up to 80% of people with Parkinson disease (PD). Little is known regarding the subjective experience and frequency of bothersome cognitive problems across the range of disease duration as expressed directly in patients' own words. We describe the types and frequency of bothersome cognitive symptoms reported verbatim by patients with PD.

Trabecular Metal Augments During Complex Primary Total Hip Arthroplasty.

Background: Trabecular metal augments (TMAs) have been extensively used in revision total hip arthroplasty (THA) to address acetabular bone defects. However, limited data exists regarding TMA utilization during primary THA. This study aims to assess the clinical and radiographic outcomes of TMAs used during primary THA.

Enhancing patient-clinician collaboration during treatment decision-making: study protocol for a community-engaged, mixed method hybrid type 1 trial of collaborative decision skills training (CDST) for veterans with psychosis.

Background: Patient participation in treatment decision making is a pillar of recovery-oriented care and is associated with improvements in empowerment and well-being. Although demand for increased involvement in treatment decision-making is high among veterans with serious mental illness, rates of involvement are low. Collaborative decision skills training (CDST) is a recovery-oriented, skills-based intervention designed to support meaningful patient participation in treatment decision making.

In Their Own Words: Fears Expressed by People with Parkinson's Disease in an Online Symptom Database.

Parkinson's disease (PD) carries substantial psychosocial burden. Using a database of responses by people with PD reporting up to five "most bothersome problems," we identified 225 fear-based verbatims, which were organized using the framework method into 26 categories. Commonly-reported fears included uncertainty of progression (n = 60, 26.

An Updated Estimate of Total Hip and Total Knee Arthroplasty Inpatient Case Volume During the 2020 COVID-19 Pandemic in the United States.

Background: Inpatient total hip arthroplasty (THA) and total knee arthroplasty (TKA) practices were dramatically affected in the United States in 2020 as elective surgeries were paused in response to the COVID-19 pandemic. This study sought to provide an updated estimate of inpatient total joint arthroplasty (TJA) case volumes in the United States in 2020.

Methods: A retrospective cohort study was performed by identifying all adult patients who underwent primary, elective TJA from January 1st, 2017 to December 31st, 2020, using the National Inpatient Sample.

Metal artifact reduction sequence-MRI abnormalities in asymptomatic patients with dual-mobility hip prostheses.

Aims: Modular dual-mobility (DM) articulations are increasingly used during total hip arthroplasty (THA). However, concerns remain regarding the metal liner modularity. This study aims to correlate metal artifact reduction sequence (MARS)-MRI abnormalities with serum metal ion levels in patients with DM articulations.

Robotic-Assisted Total Knee Arthroplasty in Obese Patients.

Background: Robotic-assisted systems have gained popularity in total knee arthroplasty (TKA). The purpose of this study was to evaluate operative characteristics and radiographic outcomes of obese patients undergoing robotic-assisted TKA.

Methods: A retrospective review of consecutive cases performed by a single surgeon was performed from January 1, 2016, to January 31, 2022.

Association between Subjective Cognitive Complaints and Incident Functional Impairment in Parkinson's Disease.

Background: Early identification of subjective cognitive complaints (SCC) in Parkinson's disease (PD) may improve patient care if it predicts cognition-related functional impairment (CFI).

Objectives: The aim was to determine the cross-sectional and longitudinal association between SCC and CFI in PD.

Methods: Data were obtained from Fox Insight, an online longitudinal study that collects PD patient-reported outcomes.

Women in Anesthesiology and the Mid-Career Stall: Why They Are Not Advancing Into Senior Leadership.

Women anesthesiologists face many challenges when trying to advance their careers and find balance in personal and professional endeavors. In this article, we introduce the reader to several concepts central to understanding the challenges faced by mid-career women anesthesiologists and highlight why these challenges become particularly pronounced when women enter the mid-career stage. We describe how lack of constructive actionable feedback combined with lack of mentorship and sponsorship negatively affects women in the workplace.
