BACKGROUND: Guideline-directed medical therapies (GDMTs), initiated in-hospital and continued during the transition to outpatient care, are paramount to successful outcomes for patients with acute coronary syndrome (ACS). Incomplete discharge medication prescribing and delayed follow-up lead to worse cardiovascular outcomes. OBJECTIVES: We investigated a system of care using inpatient and outpatient clinical pharmacists to close GDMT gaps, ensure seamless transition to outpatient care, improve patient education, and optimize therapies...

OBJECTIVE: To evaluate the effect of VR-12 MCS on postoperative patient-reported outcome measures (PROMs) after undergoing LLIF. METHODS: Retrospective data from a single-surgeon database created two cohorts: patients with VR-12 MCS ≥50 or VR-12 MCS<50. Preoperative, 6-week, and final follow-up (FF)-PROMs including VR-12 MCS/Physical Composite Score (PCS), Short Form-12 (SF-12) MCS/PCS, Patient-Reported Outcomes Measurement Information System Physical Function (PROMIS-PF), Patient Health Questionnaire-9 (PHQ-9), Visual Analog Scale (VAS)-Back/Leg Pain (VAS-BP/LP), and Oswestry Disability Index (ODI) were collected...

STUDY DESIGN: Retrospective review. OBJECTIVE: To assess the impact of Body Mass Index (BMI) on patient-reported outcome measures (PROMs) after cervical disc replacement (CDR). BACKGROUND: BMI may affect PROMs after spine surgery. METHODS: Primary CDR recipients for herniated disc(s) with BMI <40 were retrospectively selected from a single-surgeon registry. Cohorts were divided into non-obese (BMI <30) and obese (BMI ≥30)...

STUDY DESIGN: Retrospective cohort study. OBJECTIVE: To assess the impact of preoperative symptom duration (PSD) on patient-reported outcome measures (PROMs) after minimally invasive (MIS) transforaminal lumbar interbody fusion (TLIF) for degenerative spondylolisthesis (DSpond). BACKGROUND: A prolonged duration of preoperative symptoms may implicate inferior long-term outcomes postsurgery. Prior studies of lumbar fusion recipients are limited by the inclusion of heterogeneous populations...

STUDY DESIGN: Retrospective review. OBJECTIVE: To determine postoperative clinical outcomes in patients undergoing minimally invasive (MIS) transforaminal lumbar interbody fusion (TLIF) for isthmic spondylolisthesis (IS). BACKGROUND: Few studies have examined the postoperative clinical trajectory in patients undergoing MIS-TLIF specifically for IS.

STUDY DESIGN: Retrospective review. OBJECTIVE: To examine the effect of baseline Veterans RAND-12 (VR-12) Mental Composite Score (MCS) on clinical outcomes in patients undergoing cervical disk replacement (CDR) for herniated disk. BACKGROUND: Few studies in spine surgery have evaluated the impact of preoperative VR-12 MCS on postoperative outcomes in patients undergoing CDR. METHODS: Patients undergoing CDR for herniated disk were separated into 2 cohorts based on the VR-12 MCS standardized mean: VR-12 MCS<50 (worse mental health) and VR-12 MCS≥50 (better mental health)...

Technological advances in high-throughput microscopy have facilitated the acquisition of cell images at a rapid pace, and data pipelines can now extract and process thousands of image-based features from microscopy images. These features represent valuable single-cell phenotypes that contain information about cell state and biological processes. The use of these features for biological discovery is known as image-based or morphological profiling. However, these raw features need processing before use and image-based profiling lacks scalable and reproducible open-source software...
