Acute trauma can lead to life-long changes in susceptibility to psychiatric disease, such as Post-Traumatic Stress Disorder (PTSD). Rats given free access to a concentrated glucose solution for 24 hours beginning immediately after trauma failed to show stress-related pathology in the learned helplessness model of PTSD and comorbid major depression. We assessed effective dosing and temporal constraints of the glucose intervention in three experiments. We exposed 120 male Sprague-Dawley rats to 100, 1 mA, 3-15s, inescapable and unpredictable electric tail shocks (over a 110 minute period) or simple restraint in the learned helplessness procedure...

BACKGROUND: Streptococcal tonsillitis among adults is a common diagnosis. There is wide agreement regarding the recommended treatment, which is Phenoxymethyl Penicillin (Penicillin V) 1000 mg daily (usually 500 mg BID for 10 days). OBJECTIVES: Description of the variability of routine antibiotic treatment prescribed by family physicians in the community for the treatment of acute tonsillitis (which represents a common diagnosis in primary care), and observation of the prescribed antibiotics adherence to the guidelines...

Neuroplasticity represents the dynamic structural and functional reorganization of the central nervous system, including its connectivity, due to environmental and internal demands. It is recognized as a major physiological basis for adaption of cognition and behaviour, and, thus, of utmost importance for normal brain function. Cognitive dysfunctions are major symptoms in psychiatric disorders, which are often associated with pathological alteration of neuroplasticity. Transcranial direct current stimulation (tDCS), a recently developed non-invasive brain stimulation technique, is able to induce and modulate cortical plasticity in humans via the application of relatively weak current through the scalp of the head...

OBJECTIVE: Prolactinomas are the most common functional pituitary tumour. Dopamine agonists (DA) are its principal treatment. The criteria that should guide therapy withdrawal and the factors that influence disease remission or relapse are not yet fully established. Our purpose is to evaluate the proportion of patients who attempted DA withdrawal, and to identify the factors that influence clinicians to try it. In addition, we aim to study the factors that are involved in prolactinoma remission/relapse after therapy withdrawal...

Baicalein is an active component of Scutellaria baicalensis Georgi, which has traditionally been used to treat cardiovascular diseases in China. In this study, we investigated if treatment with baicalein can attenuate the lung injury induced by myocardial ischemia and reperfusion (I/R). Myocardial I/R, induced by a 40-min occlusion of the left anterior descending coronary artery and a 3-h reperfusion, significantly increased histological damage and the wet-to-dry weight ratio of lungs in rats. The terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL)-positive nuclei and caspase-3 activation was significantly increased in the lungs...

BACKGROUND AND IMPORTANCE: Aneurysms affecting double origin (DO) posterior inferior cerebellar artery (PICA) variants are rare. Most reports describe endovascular occlusion of the affected branch to treat the aneurysm, but we describe a patient in which open surgical sacrifice of 1 branch resulted in insufficient perfusion. CLINICAL PRESENTATION: We report the only case of open surgical treatment of an aneurysm affecting a leg of a DOPICA. A 42-year-old woman presenting with the worst headache of her life was found to have a DOPICA aneurysm and initially treated by trapping the aneurysm...

To position the volar plate on the distal radius fracture site, the pronator quadratus muscle needs to be detached from its distal and radial side and lifted for optimal exposure to the fracture site. Although the conventional approach involves repair of the pronator quadratus, controversy surrounds the merits of this repair. The purpose of this study was to compare the functional outcomes of patients with distal radius fractures treated with pronator quadratus repair after volar plate fixation versus no pronator quadratus repair...

INTRODUCTION: Recording cortical potentials prior to movement (bereitschaftspotentials, BP) offer a good non invasive method for studying activity of motor related cortices in Parkinson's Disease (PD). Dopaminergic medications provide some symptomatic relief in advanced stages but they do not stop the progression of the disease. Assessing BP may be a good idea to see the response of anti PD drugs. It remains unclear whether the anti PD medications also improve cortical activity prior to movement even in advanced stages of the disease...

BACKGROUND: There is growing concern about the use of opioids prior to total knee arthroplasty (TKA), and research has suggested that preoperative opioid use may lead to worse pain outcomes following surgery. We evaluated the pain relief achieved by TKA in patients who had and those who had not used opioids use before the procedure. METHODS: We augmented data from a prospective cohort study of TKA outcomes with opioid-use data abstracted from medical records. We collected patient-reported outcomes and demographic data before and 6 months after TKA...

PURPOSE OF REVIEW: In randomized clinical trials, reduction in cardiovascular disease (CVD) risk with cholesterol-lowering drugs correlates with the LDL cholesterol decrease. However, because the majority have investigated a fixed statin dose, current guidelines disagree about the use of statin dose titration or non-statin adjunctive cholesterol-lowering drugs. RECENT FINDINGS: We conducted a meta-analysis of all randomized controlled trials with CVD end-points, comparing two intensities of lipid-lowering regimens within the same population, using varying statins doses and/or potency, ezetimibe or PCSK9 inhibitors and compared the observed number of patients needed to be treated for 10 years to prevent one CVD event (NNT) with NNT predicted from trials of predominantly single-dose statin...

Neurodegenerative conditions remain difficult to treat, with the continuing failure to see therapeutic research successfully advance to clinical trials. One of the obstacles that must be overcome is to develop enhanced models of disease. Tissue engineering techniques enable us to create organised artificial central nervous system tissue that has the potential to improve the drug development process. This study presents a replicable model of neurodegenerative pathology through the use of engineered neural tissue co-cultures that can incorporate cells from various sources and allow degeneration and protection of neurons to be observed easily and measured, following exposure to neurotoxic compounds - okadaic acid and 1-methyl-4-phenylpyridinium...

The Dilemma: Estrogen receptora-negative (ER-) breast cancer lacks a specific critical target to control tumor progression. THE OBJECTIVE: To identify mechanisms that enable increased expression of the ER+ lineage in an otherwise ER- breast cancer.Preface: The nuclear receptor superfamily members PPARγ and PPARδ regulate gene expression associated with a multitude of pathways, including intermediary metabolism, angiogenesis, proliferation and inflammation (see reviews [1-3]). Recent developments using transgenic and knockout mice, as well as pharmacologic intervention with PPARγ and PPARδ agonists, have revealed a previously unknown relationship between PPARγ suppression and PPARδ activation that leads to the appearance of ER+ tumors, enabling a synthetic lethality approach by anti-ER therapy...

Peptides and proteins have been found to possess an inherent tendency to convert from their native functional states into intractable amyloid aggregates. This phenomenon is associated with a range of increasingly common human disorders, including Alzheimer and Parkinson diseases, type II diabetes, and a number of systemic amyloidoses. In this review, we describe this field of science with particular reference to the advances that have been made over the last decade in our understanding of its fundamental nature and consequences...

Melasma is a dysregulation of the homeostatic mechanisms that control skin pigmentation and excess pigment is produced. Traditional treatment approaches with topical medications and chemical peels are commonly used but due to the refractory and recurrent nature of melasma, patients often seek alternative treatment strategies such as laser and light therapy. Several types of laser and light therapy have been studied in the treatment of melasma. Intense pulsed light, low fluence Q-switched lasers, and non-ablative fractionated lasers are the most common lasers and light treatments that are currently performed...

The extract of chestnut (Castanea crenata var. dulcis) flower (CCDF) has antioxidant and antimelanogenic properties, but its anti-obesity properties have not been previously examined. In this study, we tested the effect of CCDF absolute on adipocyte differentiation by using 3T3-L1 cells and determining the bioactive component of CCDF absolute in 3T3-L1 cell differentiation. CCDF absolute (0.1-100[Formula: see text][Formula: see text]g/mL) did not change 3T3-L1 cell viability. At 50[Formula: see text][Formula: see text]g/mL and 100[Formula: see text][Formula: see text]g/mL, the absolute significantly reduced the accumulation of lipid droplets in 3T3-L1 cells that were induced by culture in medium containing 3-isobutyl-1-methylxanthine/dexamethasone/insulin (MDI)...

OBJECTIVE: Despite long-standing interest in posttraumatic stress disorder (PTSD) and opioid use disorder (OUD) comorbidity, there is a paucity of data on the prevalence of OUD in patients with PTSD. Therefore, there is limited understanding of the use of medications for OUD in this population. We determined the prevalence of diagnosed OUD and use of medications for OUD in a large cohort of patients with PTSD. METHODS: We obtained administrative and pharmacy data for Veterans who initiated PTSD treatment in the Department of Veterans Affairs (VA) between 2004 and 2013 (n = 731,520)...

PURPOSE: Most evaluations of surgical workflow or surgeon skill use simple, descriptive statistics (e.g., time) across whole procedures, thereby deemphasizing critical steps and potentially obscuring critical inefficiencies or skill deficiencies. In this work, we examine off-line, temporal clustering methods that chunk training procedures into clinically relevant surgical tasks or steps during robot-assisted surgery. METHODS: We collected system kinematics and events data from nine surgeons performing five different surgical tasks on a porcine model using the da Vinci Si surgical system...
