Stroke continues to be a major adverse event in advanced congestive heart failure (CHF) patients after continuous-flow left ventricular assist device (CF-LVAD) implantation. Abnormalities in mitochondrial oxidative phosphorylation (OxPhos) have been critically implicated in the pathogenesis of neurodegenerative diseases and cerebral ischemia. We hypothesize that prior stroke may be associated with systemic mitochondrial OxPhos abnormalities, and impaired more in post-CF-LVAD patients with risk of developing new stroke.

Objective: Minimally invasive mitral valve surgery (mini-MVS) is typically reserved for patients who have not undergone open cardiac surgery. In the reoperative setting, using intrapericardial dissection for crossclamping the aorta through a minimally invasive approach can be difficult and, at times, risky. Cold fibrillatory cardiac arrest (CFCA) with systemic cardiopulmonary bypass without cross-clamping is a well-described technique; however, data about its safety for patients who undergo reoperative mini-MVS are limited.

Objective: Isolated tricuspid valve surgery is uncommon and associated with high perioperative morbidity and mortality. We aimed to study the overall outcomes of patients who underwent minimally invasive right thoracotomy tricuspid valve surgery (Mini-TVS), consisting of either tricuspid valve repair (TVre) or replacement (TVR).

Methods: We performed a retrospective analysis of all Mini-TVS procedures (2017-2022), through which we identified isolated tricuspid valve surgeries.

Introduction: For many years, the standard of care in the USA has been to treat acute lead encephalopathy with a combination parenteral dimercaprol (BAL) and CaNaEDTA. We present a case of a pediatric patient with severe lead encephalopathy, complicated by cardiac arrest, who was treated with an alternative regimen when CaNaEDTA was unavailable.

Case Report: A 24-month-old male was brought by ambulance to an emergency department (ED) with new onset seizures and sustained a cardiac arrest.

Objectives: To examine the efficacy of continuous unilateral erector spinae plane (ESP) blocks in minimally invasive cardiac surgery patients.

Design: A retrospective nonrandomized study.

Setting: At a single-center, tertiary academic institution.

Objective: Robot-assisted coronary artery bypass (RCAB) is typically not offered to higher risk patients with reduced cardiopulmonary function, critical coronary artery disease, and challenging chest wall anatomy. In this study, we report the novel use of nonemergency intraoperative peripheral extracorporeal membrane oxygenation as partial cardiopulmonary support during RCAB for patients who were considered high-risk candidates for conventional CAB and at the same time not eligible for RCAB without cardiopulmonary support.

Methods: Forty-five high risk patients (mean age, 68 years; Society of Thoracic Surgeons score, 6.

Objective: Guided by the vulnerable population framework, the aim was to describe the risks and protective strategies for COVID-19 spread and infections in a Skilled Nursing Facility (SNF).

Method: We conducted a retrospective cohort (March 1st-August 31st, 2020) study. Data were collected from internal COVID-19 documents and resident electronic health records.

Both the Occupational Safety and Health Administration and Washington State require safety and health protections for workers exposed to respirable crystalline silica, including tuberculosis (TB) screening as part of occupational medical surveillance. We describe the creation of a TB screening tool for silica-exposed workers receiving regulated medical surveillance examinations in Washington State. The tool provides relevant clinical recommendations to assist health care providers and public health practitioners who choose to use the tool when performing such examinations.

Aldosterone sensitivity is defined as an outcome variable for a given circulating level of aldosterone. In basic and translational studies, aldosterone sensitivity has been measured in differential tissue responses, e.g.

Resistant hypertension is associated with higher rates of cardiovascular disease, kidney disease, and death than primary hypertension. Although clinical practice guidelines recommend screening for primary aldosteronism among persons with resistant hypertension, rates of screening are unknown. We identified 145 670 persons with hypertension and excluded persons with congestive heart failure or advanced chronic kidney disease.

Objective: To assess whether multifocal, high-frequency repetitive transcranial magnetic stimulation (rTMS) of motor and prefrontal cortex benefits motor and mood symptoms in patients with Parkinson disease (PD).

Methods: Patients with PD and depression were enrolled in this multicenter, double-blind, sham-controlled, parallel-group study of real or realistic (electric) sham rTMS. Patients were randomized to 1 of 4 groups: bilateral M1 ( + sham dorsolateral prefrontal cortex [DLPFC]), DLPFC ( + sham M1), M1 + DLPFC, or double sham.

Common coding theory suggests that any action (pressing a piano key) is intimately linked with its resultant sensory effect (an auditory musical tone). We conducted two experiments to explore the effect of varying auditory action-effect patterns during complex action learning. In Experiment 1, participants were assigned to 1 of 4 groups, watched a silent video of a hand playing a sequence on a piano keyboard with no auditory action effect (observation) and were asked to practise and perform the sequence on an identical keyboard with varying action effects (reproduction).

Non-motor symptoms in patients with Parkinson's disease (PD) are often poorly recognized, significantly impair quality of life and cause severe disability. Currently, there is limited evidence to guide treatment of associated psychiatric and cognitive problems. Non-invasive brain stimulation techniques have emerged as non-pharmacological alternatives to target cognitive symptoms without worsening motor function.

Background: Tumor-infiltrating lymphocytes (TILs) have been found to increase survival in many forms of cancer, including, endometrial, bile ductal, colonic, esophageal, and urothelial cancers, as well as melanoma and follicular lymphoma. The relevance of TILs in the prognosis of non-small-cell lung cancer (NSCLC), however, still remains controversial. We compared the outcomes of stage 1A NSCLC with and without tumor infiltrating lymphocytes to evaluate the effects of TILs on recurrence and survival patterns.
