BACKGROUND: Parechoviruses (HPeV) are endemic seasonal pathogens detected from the respiratory tract, gut, blood and central nervous system (CNS) of children and adults, sometimes in conjunction with a range of acute illnesses. HPeV CNS infection may lead to neurodevelopmental sequelae, especially following infection by HPeV-3, hence screening and genotyping are important to inform epidemiology, aetiology and prognosis. OBJECTIVES: To identify and characterise HPeVs circulating during an outbreak between November 2013 and April 2014 in Queensland, Australia...

PURPOSE: Intraperitoneal adhesions (IA) develop as a consequence of the healing process in peritoneum injured during surgeries. IA might be formed after all types of surgical interventions regardless the surgical approach with a higher incidence in obese individuals. Here we determine the diagnostic power of TGF-β and blood inflammatory parameters in the prediction of IA in obese patients undergoing second surgical intervention. MATERIALS AND METHODS: Eighty patients were divided into groups according to body mass index (BMI) values and presence of intraperitoneal adhesions (IA)...

The identification of blood samples is a crucial facet of forensic investigations, particularly for violent crimes. One step in forensic serology (i.e., the analysis of bodily fluids) that is often skipped or overlooked is the determination that a bloodstain is of human or nonhuman origin. Typically, subsequent to identifying a stain as blood using a presumptive blood test, which have the propensity of providing false positive results, the stain is submitted for extraction of a DNA profile to compare with those in a database...

Previous postmortem studies demonstrated dysregulation of autophagy in patients with Parkinson's disease (PD). To clarify whether this alteration reflects a fundamental aspect of PD or represents the final stage of autophagy dysregulation resulting from a long neurodegenerative process, we focused on basal autophagy in peripheral blood mononuclear cells (PBMCs) of PD patients (n = 35) and controls (n = 23). The whole-transcriptome assay revealed downregulation of mRNAs for 6 core regulators of autophagy (UNC-51-like kinase [ULK] 3, autophagy-related [Atg] 2A, Atg4B, Atg5, Atg16L1, and histone deacetylase 6)...

A quantitative analysis of zinc endopeptidases matrix metalloproteinase 9 (MMP9) and matrix metalloproteinase 3 (MMP3) from human blood serum are presented. Both matrix metalloproteinases (MMP) are present in human blood serum and can be used as biomarkers for different diseases. The analysis was performed using LC-MS/MS with a triple quadrupole mass spectrometer, based on two specific peptides of each MMP in comparison with an enzyme-linked immunosorbent assay (ELISA). While the conditions for the LC-MS/MS analysis of MMP9 peptides were previously reported for bronchoalveolar lavage fluid, the analysis of MMP3 peptides was newly quantified for human blood serum herein for the first time...

Noninvasive blood component analysis by spectroscopy has been a hotspot in biomedical engineering in recent years. Dynamic spectrum provides an excellent idea for noninvasive blood component measurement, but studies have been limited to the application of broadband light sources and high-resolution spectroscopy instruments. In order to remove redundant information, a more effective wavelength selection method has been presented in this paper. In contrast to many common wavelength selection methods, this method is based on sensing mechanism which has a clear mechanism and can effectively avoid the noise from acquisition system...

Lamotrigine (LTZ) is a phenyltriazine derivative which belongs to anti-epileptic drugs (AEDs) class and prescribed as mono- or adjunctive-therapy in treatment of epilepsy. Therapeutic drug monitoring (TDM) of AEDs provides a valid clinical tool in optimization of overall therapy. However, TDM is challenging due to the high biological samples (plasma/blood) storage/shipment costs and the limited availability of laboratories providing TDM services. Sampling in the form of dry plasma spot (DPS) or dry blood spot (DBS) are suitable alternative to overcome these issues...

Women with gestational diabetes (GDM) are a high risk group for early type 2 diabetes (T2D). Depression is a risk factor for T2D in the general population. We investigated in women after a recent pregnancy with GDM and without a clinical diagnosis of depression, whether mild to moderate depressive symptoms associate with pathologic glucose metabolism. In a cross-sectional analysis, we examined 173 women, 9 ± 3 months after delivery with several psychopathological assessments, 5-point oral glucose tolerance test with insulin, anthropometrics, and laboratory chemistry...

Lack of affordable housing access represents a significant and growing problem for low-income households in the United States and these housing challenges may present barriers to the management of chronic diseases such as type 2 diabetes. In this qualitative study, we examined how both housing challenges and housing resources shaped diabetes self-management behaviors. We conducted semi-structured interviews with 40 low-income residents of one US city, New Haven, Connecticut, who had a diagnosis of type 2 diabetes and either resided in or qualified for subsidized housing...

In a randomized, double-blind, and placebo-controlled experiment, the acute effects of gamma-aminobutyric acid (GABA) supplementation on temporal and spatial attention in young healthy adults were investigated. A hybrid two-target rapid serial visual presentation task was used to measure temporal attention and integration. Additionally, a visual search task was used to measure the speed and accuracy of spatial attention. While temporal attention depends primarily on the distribution of limited attentional resources across time, spatial attention represents the engagement and disengagement by relevant and irrelevant stimuli across the visual field...

The aim of this prospective study was to determine clinical factors associated with adverse pregnancy outcomes in women with systematic lupus erythematosus (SLE). Fifty-six pregnancies from 46 women with SLE were enrolled. Risk factors for pregnancy loss, premature delivery, hypertensive disorders of pregnancy (HDP), and light-for-date neonate (LFD), were evaluated. Univariate and multivariate logistic regression analyses revealed a history of two or more pregnancy losses before 10 gestational weeks (GW) (OR 11...

Loss of glucose homeostasis during sepsis is associated with increased organ dysfunction and higher mortality. Novel therapeutic strategies to promote euglycemia in sepsis are needed. We have previously shown that early low-level intravenous (IV) dextrose suppresses pancreatic insulin secretion and induces insulin resistance in septic mice, resulting in profound hyperglycemia and worsened systemic inflammation. In this study, we hypothesized that administration of low-level dextrose via the enteral route would stimulate intestinal incretin hormone production, potentiate insulin secretion in a glucose-dependent manner, and thereby improve glycemic control in the acute phase of sepsis...

Hypothalamic magnocellular neurons secrete vasopressin into the systemic circulation to maintain blood pressure by increasing renal water reabsorption and by vasoconstriction. When blood pressure rises, baroreflex activation normally inhibits vasopressin neurons via activation of GABAergic inputs. However, plasma vasopressin levels are paradoxically elevated in several models of hypertension and in some patients with essential hypertension, despite increased blood pressure. We have previously shown that vasopressin neuron activity is increased early in the development of moderate angiotensin II-dependent hypertension via blunted baroreflex inhibition of vasopressin neurons...

Dimitri Renard
Cerebral microbleeds (CMB) are small foci of (acute, subacute, or chronic) blood products, best seen using MRI techniques sensitive to iron deposits (i.e. gradient-echo T2*-weighted and susceptibility-weighted imaging), frequently encountered in small vessel disease (SVD, with hypertensive vasculopathy and cerebral amyloid angiopathy as most frequent conditions) and also in other disorders. In this review, we will mainly discuss the MRI characteristics of CMB and the associated MRI abnormalities encountered in common and less common SVD and non-SVD conditions...

Vascular contributions to cognitive impairment and dementia (VCID) is understood to be the second most common cause of dementia after Alzheimer's disease (AD), and is also a frequent co-morbidity with AD. While VCID is widely acknowledged as a key contributor to dementia, the mechanistic underpinnings of VCID remain poorly understood. In this review, we address the potential role of astrocytes in the pathophysiology of VCID. The vast majority of the blood vessels in the brain are surrounded by astrocytic end-feet...

BACKGROUND AND OBJECTIVES: There is considerable evidence that periconceptional maternal folate deficiency and coding variants in maternal genes coding for critical enzymes in the folate pathway are associated with neural tube defects (NTDs) in offspring. In a case-control study we investigated C677T polymorphism in the 5,10- methylenetetrahydrofolate reductase (MTHFR) gene in case and control mothers of Pakistani origin, and compared these with the respective maternal folate concentrations measured at the time of delivery...

BACKGROUND AND OBJECTIVES: Vitamin D deficiency is reportedly common, but we lack data from young adults. Such data are of interest because epidemiological data support vitamin D as a possible risk modulator for diabetes and cardiovascular ('cardiometabolic') disease. Our objectives were to assess vitamin D status (as plasma 25(OH)D concentration) and investigate associations between this and biomarkers of cardiometabolic disease risk in a group of still-healthy young adults in Hong Kong...

BACKGROUND AND OBJECTIVES: Krill oil (KO) and fish oil (FO) are good sources of health-benefiting long chain n- 3 polyunsaturated fatty acids (LC n-3 PUFA), EPA and DHA. There are conflicting outcomes on the bioavailability of LC n-3 PUFA from KO compared with FO. This study investigated the postprandial incorporation of LC n- 3 PUFA into plasma lipids following consumption of 5 capsules of KO or FO in comparison with olive oil (OO) control in healthy women. METHODS AND STUDY DESIGN: 10 women (aged 18-45 years) consumed a high-fat (15 g) breakfast, supplemented with 5 g of KO, FO, or OO in a random order with a minimum seven-day washout period between the supplementations...
