Transepithelial electrical resistance (TEER) is a widely used technique for quantifying the permeability of epithelial and endothelial cell layers. However, traditional methods of measuring TEER are limited to single timepoint measurements and can subject cells to an altered environment during the measurement. Here, we assessed the validity of TEER measurements by the ECIS TEER96 device, which is designed to take continuous TEER measurements of a cell culture system in a standard laboratory incubator.

One potential cause and frequently used exclusionary criterion in orthopedic trials is patients with active workman's compensation (WC) insurance claims. The purpose of this study is to determine demographic differences in patients undergoing arthroscopic rotator cuff repair with commercial and government insurance vs workers compensation claims.

Objective: To determine risk factors associated with prolonged opioid use after lumbar fusion and to elucidate the effect of opioid use on patient-reported outcome measures (PROMs) after surgery.
Methods: Patients who underwent 1-3 level lumbar decompression and fusion with at least one-year follow-up were identified.
Objective: Posterior cervical decompression and fusion (PCDF) is a commonly performed procedure to address cervical myelopathy. A significant number of these patients require revision surgery for adjacent-segment disease (ASD) or pseudarthrosis. Currently, there is no consensus among spine surgeons on the inclusion of proximal thoracic spine instrumentation.

Introduction: Predictors of financial costs related to total joint arthroplasty (TJA) have become increasingly important becuase payment methods have shifted from fee for service to bundled payments. The purpose of this study was to assess the relationship between preoperative opioid use and cost of care in primary TJA.
Methods: A retrospective study was conducted in Medicare patients who underwent elective unilateral primary total knee or hip arthroplasty between 2015 and 2018.
Background: Revision total joint arthroplasty (TJA) has a higher rate of periprosthetic joint infection (PJI) compared with primary TJA, possibly as the result of increased allogeneic blood transfusion. Tranexamic acid (TXA) is gaining popularity in revision TJA to minimize blood loss and the need for transfusion; however, its effect on PJI reduction has yet to be investigated. The hypothesis of this study was that the administration of TXA during revision arthroplasty is protective against subsequent PJI.

Methods: Commonly used formulas to assess renal function-the four-variable Modification of Diet in Renal Disease (MDRD), the six-variable MDRD, and the Cockcroft-Gault eGFR equations-were used to assess renal function in 100 older adult hospitalized veterans with delirium (delirium group) and 100 hospitalized veterans without delirium (nondelirium group) that were age, sex, and race matched. WML location and volumes were assessed using brain computed tomography imaging for each of the 200 veterans in the study.
Introduction: The objectives of this study are to report the rates of positive intraoperative cultures obtained during conversion total hip arthroplasty (THA) according to index surgery, and to describe the natural history of treatment for a consecutive series of patients with unexpected positive intraoperative cultures during conversion THA.
Methods: We reviewed all patients at 2 institutions undergoing conversion THA from prior open reduction and internal fixation (ORIF) of acetabular and hip fractures or hemiarthroplasty for displaced femoral neck fractures from 2011 to 2018. Intraoperative cultures were taken in 105 patients.
Objectives: To assess the experiences of a veteran initiated horticultural therapy garden during their 28-day inpatient Substance Abuse Residential Rehabilitation Treatment Program (SARRTP).
Design: Retrospective study.
Setting: Veterans Affairs Medical Center (VAMC), Salem, Virginia, USA INTERVENTIONS: Group interviews with veterans from the last SARRTP classes and individual interviews with VAMC greenhouse staff in summer of 2016.
The traditional view of integrins portrays these highly conserved cell surface receptors as mediators of cellular attachment to the extracellular matrix (ECM), and to a lesser degree, as coordinators of leukocyte adhesion to the endothelium. These canonical activities are indispensable; however, there is also a wide variety of integrin functions mediated by non-ECM ligands that transcend the traditional roles of integrins. Some of these unorthodox roles involve cell-cell interactions and are engaged to support immune functions such as leukocyte transmigration, recognition of opsonization factors, and stimulation of neutrophil extracellular traps.

Concerns have been raised about bupropion's propensity to precipitate new psychosis and worsen existing psychotic symptoms, although the mechanism is poorly understood. Three cases are reported in which bupropion use was associated with psychosis.

The aim of this research was to investigate, using case-control retrospective chart review, the association of white matter lesions (WML), cerebral atrophy, intracranial extravascular calcifications, and ventricular-communicating hydrocephalus in older adult military veterans with and without delirium hospitalized in a Veterans Affairs Medical Center.
Methods: Head CT scans were examined for WML, atrophy, and intracranial extravascular calcifications globally in the cortex, subcortex (frontal, temporal, parietal, occipital lobes), basal ganglia (globus pallidus, caudate, putamen), and internal capsule, in addition to the presence of ventricular-communicating hydrocephalus.
The effectiveness of medications for PTSD in general has been well studied, but the effectiveness of medicatio.ns prescribed specifically for post-traumatic stress disorder (PTSD) nightmares is less well known. This retrospective chart review examined the efficacy of various medications used in actual treatment of PTSD nightmares at one Veteran Affairs Hospital.

The object of this study was to assess the effectiveness of AMD documentation at a local Veterans Affairs Medical Center. AMD documentation was compared among three inpatient services: surgery, medicine, and psychiatry.

In this retrospective study, the records of 183 hospitalized veterans admitted to the emergency department (ED), medicine, surgery and psychiatry services and coded as not having a diagnosis of delirium were analyzed. Clinical notes of each case were examined using DSM IV TR criteria for delirium.

A great majority (19) of the case studies did not meet the requirements of all 7 guidelines, frequently due to unreported information. Nor was quetiapine proven to be the sole cause of the possible NMS in the two age groups investigated.

Preliminary studies have reported the benefits of horticultural therapy and garden settings in reduction of pain, improvement in attention, lessening of stress, modulation of agitation, lowering of as needed medications, antipsychotics and reduction of falls. This is especially relevant for both the United States and the Republic of Korea since aging is occurring at an unprecedented rate, with Korea experiencing some of the world's greatest increases in elderly populations.

Objective: Bupropion is a substituted phenyl-ethylamine that is extensively utilized for the treatment of major depressive disorder and for smoking cessation. It is a reuptake inhibitor of dopamine and norepinephrine, and it also has some nicotinic antagonism. There are concerns that it may increase the risk of psychosis due to its dopaminergic effects.
