Near-Peer Supervision in Primary Care: Bringing Teaching Teams From the Wards to the Clinic.

Background: Teaching near-peers yields numerous benefits to residents. Opportunities for near-peer teaching are typically restricted to hospital settings. Little is known about the educational potential of outpatient near-peer teaching.

A case study of recurrent myocardial infarction secondary to socioeconomic challenges and nonadherence: Pre-discharge screening.

Medication nonadherence following myocardial infarction (MI) is prevalent and increases the risk of recurrent cardiovascular events. Socioeconomic factors including medication cost, financial insecurity, and poor health literacy are associated with nonadherence. We present a patient with a history of recurrent MI who was nonadherent due to socioeconomic challenges.

Blood Pressure and Living Kidney Donors: A Clinical Perspective.

Elevated blood pressure (BP), or "hypertension," has been one of the main exclusion criteria for living kidney donation, as it is a risk factor for renal and cardiovascular disease. The effect of elevated BP in living kidney donors is not well studied or understood. The most current living kidney donation guidelines state that donors with a BP >140/90 mm Hg with 1-2 antihypertensive medications or evidence of end-organ damage should be excluded from living kidney donation.

Continuous Transversus Abdominis Plane Block for Primary Open Inguinal Hernia Repair: A Randomized, Double-Blind, Placebo-Controlled Trial.

Objective: Patients undergoing open inguinal hernia repair may experience moderate to severe postoperative pain. We assessed opioid consumption in subjects who received a continuous transversus abdominis plane block in addition to standard multimodal analgesia.

Design: Randomized, double-blind, placebo-controlled.

Comparison of Anterior Suprascapular, Supraclavicular, and Interscalene Nerve Block Approaches for Major Outpatient Arthroscopic Shoulder Surgery: A Randomized, Double-blind, Noninferiority Trial.

Background: The interscalene nerve block provides analgesia for shoulder surgery, but is associated with diaphragm paralysis. One solution may be performing brachial plexus blocks more distally. This noninferiority study evaluated analgesia for blocks at the supraclavicular and anterior suprascapular levels, comparing them individually to the interscalene approach.

Comparison of Continuous Proximal Versus Distal Adductor Canal Blocks for Total Knee Arthroplasty: A Randomized, Double-Blind, Noninferiority Trial.

Background And Objectives: Adductor canal blocks (ACBs) are associated with improved analgesia, preserved quadriceps strength, and decreased length of hospitalization after total knee arthroplasty (TKA). However, controversy remains regarding the ideal location of a continuous block within the adductor canal, and it remains unclear whether similar clinical benefits are obtained irrespective of block location. In this randomized, double-blind, noninferiority study, we hypothesized that a continuous proximal ACB provides postoperative analgesia that is no worse than a continuous distal ACB.

A Double-Blind Randomized Comparison of Continuous Interscalene, Supraclavicular, and Suprascapular Blocks for Total Shoulder Arthroplasty.

Background And Objectives: Continuous brachial plexus blocks at the interscalene level are associated with known diaphragm dysfunction from phrenic nerve paresis. More distal blocks along the brachial plexus may provide postsurgical analgesia while potentially having less effect on diaphragm function. Continuous interscalene, continuous supraclavicular, and continuous suprascapular nerve blocks were evaluated for respiratory function and analgesia after total shoulder arthroplasty.

Evaluation of Ultrasound-Assisted Thoracic Epidural Placement in Patients Undergoing Upper Abdominal and Thoracic Surgery: A Randomized, Double-Blind Study.

Background And Objectives: The placement of thoracic epidurals can be technically challenging and requires a thorough understanding of neuraxial anatomy. Although ultrasound imaging of the thoracic spine has been described, no outcome studies on the use of this imaging have been performed. We evaluated whether preprocedural ultrasound of the thoracic spine would facilitate the process of epidural catheterization.

Continuous ambulatory adductor canal catheters for patients undergoing knee arthroplasty surgery.

Study Objective: To determine after knee arthroplasty surgery the feasibility of discharging patients home on postoperative day 1 with continuous adductor canal blocks.

Design: Retrospective case series.

Setting: Outpatient setting after hospital discharge.

Neural Network Prediction of ICU Length of Stay Following Cardiac Surgery Based on Pre-Incision Variables.

Background: Advanced predictive analytical techniques are being increasingly applied to clinical risk assessment. This study compared a neural network model to several other models in predicting the length of stay (LOS) in the cardiac surgical intensive care unit (ICU) based on pre-incision patient characteristics.

Methods: Thirty six variables collected from 185 cardiac surgical patients were analyzed for contribution to ICU LOS.

A randomized crossover study comparing a novel needle guidance technology for simulated internal jugular vein cannulation.

Background: Despite ultrasound guidance for central line placement, complications persist, as exact needle location is often difficult to confirm with standard two-dimension ultrasound. A novel real-time needle guidance technology has recently become available (eZono, Germany) that tracks the needle during insertion. This randomized, blinded, crossover study examined whether this needle guidance technology improved cannulation of a simulated internal jugular (IJ) vein in an ultrasound phantom.

Testing the initial efficacy of a mailed screening and brief feedback intervention to reduce at-risk drinking in middle-aged and older adults: the comorbidity alcohol risk evaluation study.

Objectives: To determine the initial efficacy of a mailed screening and brief intervention to reduce at-risk drinking in persons aged 50 and older.

Design: Pilot randomized controlled trial.

Setting: University of California at Los Angeles Department of Medicine Community Offices and Primary Care Network.

Fluoroscopic evaluation of contrast distribution within the adductor canal.

Background And Objectives: This case series assesses the in vivo spread of contrast within the adductor canal in subjects who recently underwent a total knee arthroplasty. A previous analysis of profound leg weakness with a continuous adductor canal revealed contrast spread from the adductor canal to the femoral triangle with as little as 2 mL of volume.

Methods: We enrolled 10 American Society of Anesthesiologists class II-III subjects.
