Afferent neurotransmission to hippocampal pyramidal cells can lead to long-term changes to their intrinsic membrane properties and affect many ion currents. One of the most plastic neuronal currents is the hyperpolarization activated cationic current (Ih ), which changes in CA1 pyramidal cells in response to many types of physiological and pathological processes, including auditory stimulation. Recently we demonstrated that long-term potentiation (LTP) in rat hippocampal Schaffer-CA1 synapses is depressed by high-intensity sound stimulation...

BACKGROUND: To evaluate the predictive value of dialysate interleukin-6 (IL-6) representing local subclinical intraperitoneal inflammation for the development of peritonitis in continuous ambulatory peritoneal dialysis (CAPD) patients. METHODS: Stable prevalent CAPD patients were enrolled in this prospective study. IL-6 concentration in the overnight effluent was determined and expressed as the IL-6 appearance rate (IL-6AR). Patients were divided into 2 groups according to the median of IL-6AR and prospectively followed up until the first episode of peritonitis, cessation of PD, or the end of the study (December 30, 2017)...

BACKGROUND: Immune system dysregulation is critical in the physiopathology of major depressive disorder (MDD) and bipolar disorder (BD). However, it is unclear whether both diseases present the same inflammatory patterns during depressive episodes. We explored the differences in pro- and anti-inflammatory cytokines between unipolar and bipolar depression (BDD) and the trajectory of these cytokines after acute-phase treatment. METHODS: Sixty-four MDD patients, 61 BDD patients, and 62 healthy controls (HCs) were enrolled...

A robust finding in recognition memory is that performance declines monotonically across test trials. Despite the prevalence of this decline, there is a lack of consensus on the mechanism responsible. Three hypotheses have been put forward: (1) interference is caused by learning of test items (2) the test items cause a shift in the context representation used to cue memory and (3) participants change their speed-accuracy thresholds through the course of testing. We implemented all three possibilities in a combined model of recognition memory and decision making, which inherits the memory retrieval elements of the Osth and Dennis (2015) model and uses the diffusion decision model (DDM: Ratcliff, 1978) to generate choice and response times...

A supra-annual, community-level synchronous flowering prevails in several parts of the tropical forests of Southeast Asia and its evolution has been hypothesized to be linked to pollinator shifts. The aseasonal Southeast Asian lowland rainforests are dominated by Dipterocarpaceae, which exhibit great floral diversity, a range of pollination syndromes and include species with annual and supra-annual gregarious flowering. Phylogenetic relationships within this family are still unclear, especially in the tribe Shoreeae...

BACKGROUND & AIMS: Intestinal failure associated liver disease (IFALD) has been defined using numerous criteria; however the clinical relevance of these criteria has never been compared. We therefore aimed to evaluate the prevalence, incidence, evolution of IFALD diagnosed by different criteria and to assess any clinical features that may be associated with its occurrence. METHODS: A cross sectional (CS) and retrospective study were carried out on adults on home parenteral nutrition (HPN) for chronic intestinal failure (CIF) managed at a single center...

BACKGROUND: Patterns in non-medical prescription opioid (NMPO) and heroin use have recently shifted, with evidence that NMPO-only users transition to NMPO and heroin co-use. Co-use is associated with increased risk of morbidity and overdose, highlighting the need for further investigation. This study aims to quantify, describe, and explore trends in co-use. METHODS: Using data from the 2003-2014 National Surveys on Drug Use and Health, we compared co-use to NMPO- and heroin-only use across demographic, substance use and mental health characteristics with chi-squared tests...

Movement disorders are increasingly identified in infantile encephalopathies due to single gene disorders (e.g. SCN2A, CDKL5, ARX). The associated movement disorder can be challenging to recognise and treat. We report a 2 year-old boy with a background history of Ohtahara syndrome due to a missense variant in ARX (the aristaless-related homeobox gene) who subsequently developed status dystonicus. ARX is a transcription factor that plays a critical role in cortical neuronal development and is associated with a range of important neurodevelopmental disorders depending on the site of the pathogenic variant...

Psychotic experiences (PEs) are associated with a range of mental and physical disorders, and disability, but little is known about the association between PEs and aspects of health-related quality of life (HRQoL). We aimed to investigate the association between PEs and five HRQoL indicators with various adjustments. Using data from the WHO World Mental Health surveys (n = 33,370 adult respondents from 19 countries), we assessed for PEs and five HRQoL indicators (self-rated physical or mental health, perceived level of stigma (embarrassment and discrimination), and social network burden)...

CONTEXT: Hypothyroidism is a significant cause of pericardial effusion. However, large pericardial effusions due to hypothyroidism are extremely rare. Hormone replacement therapy is the cornerstone of treatment for hypothyroidism and regular follow-up of patients after initiation of the therapy is indicated. Herein, the case of a 70-year-old woman with a massive pericardial effusion due to Hashimoto's disease is presented. ISSUES: A 70-year-old female from a rural village on the island of Crete, Greece, was admitted to our hospital due to a urinary tract infection...

Heavy episodic alcohol consumption (also termed binge drinking) contributes to a wide range of health and cognitive deficits, but the associated brain-based indices are poorly understood. The current study used electroencephalography (EEG) to examine spontaneous neural oscillations in young adults as a function of quantity, frequency, and the pattern of their alcohol consumption. Sixty-one young adults (23.4 ± 3.4 years of age) were assigned to binge drinking (BD) and light drinking (LD) groups that were equated on gender, race/ethnic identity, age, educational background, and family history of alcoholism...

Rates of disordered eating may be higher among women veterans than civilians, and are associated with co-occurring mental health (MH) conditions, such as depression, post-traumatic stress disorder (PTSD), and alcohol misuse. Although evidence suggests that these conditions are common in primary care settings, limited research has examined symptoms of disordered eating among women veterans in primary care. This study used a cross-sectional design to examine rates and MH correlates of disordered eating among women veterans treated in a primary care setting...

AIMS: Chronic ischemia is a recognized factor in the pathophysiology of underactive bladder (UAB). Although relative ischemia (ie, low blood flow) is known to occur during filling, little is known regarding the pathophysiology that leads to UAB. Therefore, we developed an ex vivo functional porcine model to investigate the role of transient ischemia and whether autoregulation, a mechanism that maintains tissue oxygenation in certain vital organs, also exists in the bladder. METHODS: Using bladders from slaughtered pigs, we prepared an isolated perfused model where we studied the effects of bladder perfusion flow rate on perfusion pressure and tissue oxygenation during the filling phase...

Pediatric HSCT recipients are at high risk for CMV reactivation due to their immature immune system and therapy following transplantation. Reconstitution of CMV-specific T-cell immunity is associated with control and protection against CMV. The clinical utility of monitoring CMV-specific CMI to predict CMV viremia in pediatric HSCT patients using the Quantiferon-CMV (QIAGEN® ) test was investigated prospectively. Thirty-seven pediatric allogeneic HSCT recipients were enrolled from 3/2010-6/2012. CMV viremia was detected via weekly real-time PCR...

OBJECTIVE: To evaluate the effectiveness of dental treatment in improving oral health in critical patients. METHODS: This randomised clinical trial was conducted in a general intensive care unit (ICU) at a tertiary care public facility from 1 January 2011 to 8 August 2013. Data from 254 adult patients staying in the ICU for 48 hours or more were analysed. The experimental group (n = 127) had access to dental treatment provided by a dentist four to five times a week, in addition to routine oral hygiene, whereas the control group (n = 127) had access only to routine oral hygiene, including topical application of chlorhexidine, provided by the ICU nursing staff...

Factors other than HIV/AIDS may influence the cognitive function of patients living with this disease. The present study tested the influence of a common comorbid problem-an overweight body mass. It also examined intra-task variabilities in performance and brain activation as potentially more sensitive indicators of dysfunction than their mean levels. One-hundred seventy-eight participants were recruited and categorized by HIV-1 serostatus (-/+) and body mass (BMI < 26/≥ 26 kg/m2 ). They performed a simple time estimation task during which response time accuracy and electroencephalographic readiness potentials were recorded...

PURPOSE: Only a third of children with cancer and febrile neutropenia (FN) have a proven bacterial infection; nevertheless, most children are hospitalized and treated with intravenous antibiotics. Several biomarkers have been proposed as predictive markers for bacterial infection in this population. We aimed to evaluate the role of interleukin-6 (IL-6) and procalcitonin (PCT) in diagnosing bacterial infection in children with cancer and FN. METHODS: The study population was derived from a prospective database (2006-2013, IL-8 study) comprising children with cancer who presented with FN...

Behçet's disease is a chronic inflammatory condition of unknown origin characterized by multiple organ involvement. The most common symptoms of Behçet's disease are recurrent oral and/or genital ulcerations in combination with symptoms affecting eyes, skin, central and peripheral nervous system, blood vessels and gastrointestinal tract. We present a 43-year-old female patient with the history of recurrent episodes of genital and oral ulcerations, elevated acute phase reactants and skin lesions. The diagnosis of Behçet's disease has been delayed (for more than 10 years) and reached only after she developed neurological and ocular symptoms...

OBJECTIVES: Approximately 5%-10% of adults with congenital heart disease (CHD) develop pulmonary arterial hypertension (PAH), which affects life expectancy and quality of life. Arrhythmias are common among these patients, but their incidence and impact on outcome remains uncertain. METHODS: All adult patients with PAH associated with CHD (PAH-CHD) seen in a tertiary centre between 2007 and 2015 were followed for new-onset atrial or ventricular arrhythmia. Clinical variables associated with arrhythmia and their relation to mortality were assessed using Cox analysis...
