Sleep disturbance in adults with chronic pruritic dermatoses is associated with increased C-reactive protein levels.

Background: Pruritus is a common symptom that can significantly reduce quality of life through sleep disruption.

Objective: To examine features of disturbed sleep in patients with chronic pruritic dermatoses and test the hypothesis that systemic inflammation may serve as a biomarker for impaired sleep in these patients.

Methods: Cross-sectional analysis of the National Health and Nutrition Examination Survey investigating systemic inflammation using C-reactive protein (CRP) levels.

Comorbidities in Mycosis Fungoides and Racial Differences in Co-Existent Lymphomatoid Papulosis: A Cross-Sectional Study of 580 Patients in an Urban Tertiary Care Center.

Mycosis fungoides (MF) is a cutaneous T-cell lymphoma. Previous reports have suggested MF is associated with inflammatory conditions such as psoriasis, increased cardiovascular risk factors as well as secondary neoplasms. A cross-sectional study of MF patients seen from 2013 to 2019 was performed.

Preexisting smooth muscle cells contribute to neointimal cell repopulation at an incidence varying widely among individual lesions.

Background: With the diverse origin of neointimal cells, previous studies have documented differences of neointimal cell lineage composition across models, but the animal-to-animal difference has not attracted much attention, although the cellular heterogeneity may impact neointimal growth and its response to therapeutic interventions.

Methods: R26R(+);Myh11-CreER(+), and R26R(+);Scl-CreER(+) mice were used to attach LacZ tags to the preexisting smooth muscle cells (SMCs) and endothelial cells (ECs), respectively. Neointimal lesions were created via complete ligation of the common carotid artery (CCA) and transluminal injury to the femoral artery (FA).

Emerging national trends in the management and outcomes of lower extremity peripheral arterial disease.

Background: In this study, we sought to analyze emerging national trends in the treatment of lower extremity peripheral arterial disease and associated outcomes.

Methods: The Nationwide Inpatient Sample was queried between 2001 and 2007. Patients diagnosed with lower extremity atherosclerosis were selected by using the International Classification of Diseases, 9th Revision codes 440.

The advent of thoracic endovascular aortic repair is associated with broadened treatment eligibility and decreased overall mortality in traumatic thoracic aortic injury.

Background: Aortic injury is the second leading cause of death in trauma. Thoracic endovascular aortic repair (TEVAR) has recently been applied to traumatic thoracic aortic injuries (TTAIs) as a minimally invasive alternative to open surgery. We sought to determine the impact of TEVAR on national trends in the management of TTAI.

Heparin-induced thrombocytopenia: a practical review.

Heparin-induced thrombocytopenia (HIT) remains under-recognized despite its potentially devastating outcomes. It begins when heparin exposure stimulates the formation of heparin-platelet factor 4 antibodies, which in turn triggers the release of procoagulant platelet particles. Thrombosis and thrombocytopenia that follow comprise the 2 hallmark traits of HIT, with the former largely responsible for significant vascular complications.

Time-lapse mapping of cortical changes in schizophrenia with different treatments.

Using time-lapse maps, we visualized the dynamics of schizophrenia progression, revealing spreading cortical changes that depend on the type of antipsychotic treatment. Dynamic, 4-dimensional models of disease progression were created from 4 repeated high-resolution brain magnetic resonance imaging scans of 36 first-episode schizophrenia patients (30 men/6 women; mean age: 24.2 +/- 5.

Review of the best case series methodology: best case series results of East-West Cancer Center.

Purpose: To assess the efficacy of the best case series program methodology as a preliminary evaluation of complementary and alternative programs.

Setting: East-West Cancer Center (EWCC) is a traditional oriental cancer center located in Daejeon, Korea. Cancer patients received Wheel balance therapy (WBT), which focuses on rediscovering homeostatic harmony with dietary therapy, metabolism-activating therapy, antiangiogenesis and immune system therapy, and controlled breathing and psychotherapy.

Cerebral metabolic dysfunction and impaired vigilance in recently abstinent methamphetamine abusers.

Background: Methamphetamine (MA) abusers have cognitive deficits, abnormal metabolic activity and structural deficits in limbic and paralimbic cortices, and reduced hippocampal volume. The links between cognitive impairment and these cerebral abnormalities are not established.

Methods: We assessed cerebral glucose metabolism with [F-18]fluorodeoxyglucose positron emission tomography in 17 abstinent (4 to 7 days) methamphetamine users and 16 control subjects performing an auditory vigilance task and obtained structural magnetic resonance brain scans.

Mapping hippocampal and ventricular change in Alzheimer disease.

We developed an anatomical mapping technique to detect hippocampal and ventricular changes in Alzheimer disease (AD). The resulting maps are sensitive to longitudinal changes in brain structure as the disease progresses. An anatomical surface modeling approach was combined with surface-based statistics to visualize the region and rate of atrophy in serial MRI scans and isolate where these changes link with cognitive decline.

Structural abnormalities in the brains of human subjects who use methamphetamine.

We visualize, for the first time, the profile of structural deficits in the human brain associated with chronic methamphetamine (MA) abuse. Studies of human subjects who have used MA chronically have revealed deficits in dopaminergic and serotonergic systems and cerebral metabolic abnormalities. Using magnetic resonance imaging (MRI) and new computational brain-mapping techniques, we determined the pattern of structural brain alterations associated with chronic MA abuse in human subjects and related these deficits to cognitive impairment.

Dynamics of gray matter loss in Alzheimer's disease.

We detected and mapped a dynamically spreading wave of gray matter loss in the brains of patients with Alzheimer's disease (AD). The loss pattern was visualized in four dimensions as it spread over time from temporal and limbic cortices into frontal and occipital brain regions, sparing sensorimotor cortices. The shifting deficits were asymmetric (left hemisphere > right hemisphere) and correlated with progressively declining cognitive status (p < 0.
