Significance There has been an emerging interest in sleep and its association with β-amyloid burden as a risk factor for Alzheimer’s disease. Despite the evidence that acute deprivation elevates levels mouse interstitial fluid human cerebrospinal fluid, not much is known about impact of on brain. Using positron emission tomography, here we show impacts brain regions have implicated Our observations provide preliminary negative effect
Our study sought to determine whether there was a change in emergency department (ED) length of stay (LOS) during the coronavirus disease 2019 (COVID-19) pandemic compared prior years.
Neuroinflammation appears to contribute neurotoxicity observed with heavy alcohol consumption. To assess whether chronic results in neuroinflammation we used PET and [11C]PBR28, a ligand that binds the 18-kDa translocator protein (TSPO), compare participants an use disorder (AUD: n = 19) healthy controls (HC: 17), alcohol-dependent (n 9) -nondependent rats 10). Because TSPO is implicated cholesterol's transport for steroidogenesis, investigated plasma cholesterol levels influenced [11C]PBR28...
Introduction: The novel coronavirus 2019 (COVID-19) pandemic in the United States (US) prompted widespread containment measures such as shelter-in-place (SIP) orders. goal of our study was to determine whether there a significant change overall volume and proportion emergency department (ED) encounters since SIP began.Methods: This retrospective, observational, cross-sectional using billing data from January 1, 2017–April 20, 2020. We received 141 EDs across 16 states, encompassing...
Purpose Vascular access patients with central vein (CV) stenosis or occlusion may have significant symptoms. Treatment is generally by balloon angioplasty, without stenting. However, CV lesions not be correctable and when treated, tend to recur. Surgical bypass of obstruction a major procedure ligation the leave patient dependent on catheter dialysis. We review precision inflow banding limit vascular flow pressure for symptomatic while preserving functionality. Materials Methods All...
It remains unclear whether resting state functional magnetic resonance imaging (rfMRI) networks are associated with underlying synchrony in energy demand, as measured by dynamic 2-deoxy-2-[ 18 F]fluoroglucose (FDG) positron emission tomography (PET). We absolute glucose metabolism, temporal metabolic connectivity (t-MC) and rfMRI patterns 53 healthy participants at rest. Twenty-two emerged from group independent component analysis (gICA). In contrast, only two anti-correlated t-MC FDG-PET...
Recurrent cephalic arch stenosis (CAS) has been linked to high flow and a rate of recurrence following angioplasty. This study investigates the effectiveness access reduction in decreasing rapidly recurrent symptomatic CAS.A retrospective patient records from February 2005 April 2009 was conducted. Patients with brachiocephalic fistulas who had undergone two or more instances angioplasty within 3 months, thereafter underwent via banding inflow (n=33) were included. A before-and-after...
ObjectiveCephalic arch stenosis (CAS) is a frequent and challenging failure mode of brachiocephalic fistulas. Natural tortuosity the cephalic requires special consideration in selecting treatment modality. Typical percutaneous angioplasty bare-metal stent (BMS) treatments provide short-term solution for CAS without durable effect. This study assessed Viabahn (W. L. Gore & Associates, Flagstaff, Ariz) grafts (SGs) as first-line option to CAS.MethodsSG data were collected at free-standing...
To establish an effective approach for diagnosis and treatment of hand ischemia in matured radiocephalic arteriovenous fistulae (AVF).One hundred fifty end-stage renal disease patients (4% our practice) presented to outpatient vascular access facility complaining a range symptoms including coldness, numbness pain the fingers indicative due steal syndrome. In 15 syndrome were limited fingers, sparing hand. Physical examination was caused by shunting blood from ulnar artery via palmar arch,...
Purpose To establish a standardized approach for the maturation of non-maturing arteriovenous fistulae. Methods consecutive patients (n=122) with fistulae presented to our outpatient vascular access center percutaneous interventions assist in maturation. The techniques used included flow rerouting, competing branch vein elimination, staged balloon angioplasty, and limited controlled extravasation. Results Successful fistula maturations were achieved 118/122 patients. Fistulae divided into...
Abstract Thrombosed immature fistulas have historically been considered unsalvageable. However, advances in procedure and balloon catheter technologies expanded the scope of endovascular treatments. This study investigates efficacy, functionality, cost associated with use percutaneous techniques for salvage thrombosed fistulas. Over a 2‐year period from population 18,000 patients on hemodialysis, 140 consecutive underwent attempts at via thrombectomy procedures. All had following access...

The objectives of this study were to determine the prevalence risk behaviors, gonorrhea, and chlamydia in clients female sex workers, compare them with men selected from general population.We conducted a cross-sectional recruited commercial venues Lima, Peru January February 2002. Subjects answered survey provided urine sample.Men reported that recently concluded encounter, 95.8% used condoms, 85.8% always condoms workers. Only 16% using their stable partners; 50.8% casual, noncommercial...
Introduction: The short-term return visit rate among patients discharged from emergency departments (ED) is a quality metric and target for interventions. ability to accurately identify which are more likely revisit the ED could allow EDs health systems develop focused interventions, but efforts reduce revisits have not yet found success. Whether with high number of visits at increased risk remains underexplored.Methods: This was population-based, retrospective, cohort study using...
Schizophrenia is a severe and complex mental disorder that causes an enormous societal financial burden. Following the identification of dopamine as neurotransmitter invention antipsychotic drugs, hypothesis was formulated to suggest hyperdopaminergia cause schizophrenia. Over time there have been modifications improvements dopamine-based model schizophrenia, well models do not implicate dysregulation primary disease. It seems clear by now disruption homeostasis occurs in schizophrenia...
Purpose To assess the effectiveness of sharp needle recanalization (SNR) for treatment chronically occluded venous outflow in hemodialysis access. Methods A retrospective analysis patient records from January 2006 to March 2010 was conducted. Forty-four patients (31 fistulas, 13 grafts) were referred arm swelling (18%), excessive bleeding after dialysis (29%), and thrombosis (53%). All had chronic occlusion vein which failed conventional techniques. new pathway established by advancing a 21g...
