Effects of deep brain stimulation on cognitive functioning in treatment-resistant depression: a systematic review and meta-analysis.

Deep brain stimulation (DBS) is a promising intervention for treatment-resistant depression (TRD). Effects on cognitive functioning are unclear since they have been studied in small samples. We aim to estimate the impact of DBS on cognitive functioning in TRD with a systematic review and meta-analyses.

Chemical reactivity, molecular electrostatic potential and in-silico analysis on benzimidazole fungicide benomyl.

We are reporting theoretical concepts and biological activity of benomyl using different techniques. The molecular orbital contributions are studied by using Total Density of States (TDOS) analysis. The chemical reactivity of the molecule have been determined with the help of global reactivity descriptors.

Extraction and analysis of free amino acids and 5'-nucleotides, the key contributors to the umami taste of seaweed.

Assessing the umami taste of seaweed on a chemical level can inform the use and selection of seaweed in European cuisine. Accordingly, we developed a method for the simultaneous extraction, separate clean-up and analysis of 21 free amino acids and 10 free nucleotides by reversed phase and mixed-mode HPLC respectively. Of multiple mouth emulating solvents, extracting in Milli-Q at 35 °C was found most suitable.

Perioperative bridging of anticoagulation: towards a more reserved approach.

Background: Most invasive procedures require the interruption of oral anticoagulation. In 2015, an international randomised trial demonstrated that perioperative bridging caused more harm than benefit in most anticoagulated patients with atrial fibrillation, leading to a more restrictive Dutch national guideline in April 2016. The objective of the present study was to analyse the integration of the 2016 Dutch guideline for perioperative antithrombotic management from after publication until update of hospital protocols.

Elastic compression stockings one year after DVT diagnosis: Who might discontinue?

Background: Elastic compression stockings (ECS) are uncomfortable to wear but may prevent post-thrombotic syndrome (PTS). The ability to predict PTS may help clinical decision making regarding the optimal duration of ECS after deep vein thrombosis (DVT).

Aims: Predefined endpoint analysis of the Octavia study that randomized patients who compliantly used ECS up to one year after DVT to continue or discontinue ECS treatment.

Predictors of cognitive performance in bipolar disorder: The role of educational degree and inflammatory markers.

Background: The aim of this article was to evaluate the cognitive status of remitted patients with bipolar disorder (BD) using Mini-Mental State Examination (MMSE), Frontal Assessment Battery, and Brief Assessment of Cognition in Affective Disorders (BAC-A). The BAC-A is a comprehensive test battery addressing the cognitive domains compromised in BD. We also aimed to analyze potential clinical and immune predictors of cognitive performance in BD.

Predicting Post-Thrombotic Syndrome with Ultrasonographic Follow-Up after Deep Vein Thrombosis: A Systematic Review and Meta-Analysis.

Background:  Post-thrombotic syndrome (PTS) is a common and potential severe complication of deep venous thrombosis (DVT). Elastic compression stocking therapy may prevent PTS if worn on a daily basis, but stockings are cumbersome to apply and uncomfortable to wear. Hence, identification of predictors of PTS may help physicians to select patients at high risk of PTS.

Radiography of the distal extremity of the manus in the donkey foal: Normal images and quantitative characterization from birth to 2 years of age: A pilot study.

This study describes a radiographic survey of the anatomical development of the distal extremity of the manus in the donkey from 0 to 2 years of age. The right distal limb of 10 donkey foals, born in the spring of 2012, underwent radiographs every month for the first 6 months of age and every 3 months during the following 18 months. Latero-medial radiographs with and without barium marker at the coronary band and dorso-palmar radiographs with both front feet in weight bearing were obtained.

White muscle disease in foals: focus on selenium soil content. A case series.

Background: White muscle disease (WMD) is a nutritional myopathy caused by selenium (Se) deficiency. In most soils, Se is present in low concentrations, sometimes even below 0.2 mg/kg, a trend which is seen in many countries.

One versus two years of elastic compression stockings for prevention of post-thrombotic syndrome (OCTAVIA study): randomised controlled trial.

Objective:  To study whether stopping elastic compression stockings (ECS) after 12 months is non-inferior to continuing them for 24 months after proximal deep venous thrombosis.

Design:  Multicentre single blind non-inferiority randomised controlled trial.

Setting:  Outpatient clinics in eight teaching hospitals in the Netherlands, including one university medical centre.

Evaluation of the new simple and objective clinical decision rule "I-DVT" in patients with clinically suspected acute deep vein thrombosis.

Introduction: The Wells rule is the recommended first step in the work-up of suspected deep vein thrombosis (DVT). However, it is often incorrectly used leading to an excessive number of diagnostic tests used in daily practice and diagnostic failures. A simpler objective risk stratification tool may improve adherence to the guidelines.

Product ion isotopologue pattern: A tool to improve the reliability of elemental composition elucidations of unknown compounds in complex matrices.

Rationale: Elucidation of the elemental compositions of unknown compounds (e.g., in metabolomics) generally relies on the availability of accurate masses and isotopic ratios.

Magnetic resonance direct thrombus imaging differentiates acute recurrent ipsilateral deep vein thrombosis from residual thrombosis.

Accurate diagnostic assessment of suspected ipsilateral recurrent deep vein thrombosis (DVT) is a major clinical challenge because differentiating between acute recurrent thrombosis and residual thrombosis is difficult with compression ultrasonography (CUS). We evaluated noninvasive magnetic resonance direct thrombus imaging (MRDTI) in a prospective study of 39 patients with symptomatic recurrent ipsilateral DVT (incompressibility of a different proximal venous segment than at the prior DVT) and 42 asymptomatic patients with at least 6-month-old chronic residual thrombi and normal D-dimer levels. All patients were subjected to MRDTI.

Internalization of mRNA lipoplexes by dendritic cells.

Lipoplexes, composed of Lipofectamine and mRNA encoding HIV Gag protein, were shown to be internalized by dendritic cells (DCs) and promote antigen presentation to stimulate HIV-specific T cell responses. Using confocal microscopy, we showed that one-third of fluorescently labeled mRNA containing lipoplexes are colocalized with late endosomes. We further investigated the effect of inhibitors, blocking phagocytosis, macropinocytosis, and clathrin- and caveolae-mediated endocytosis, on both the internalization of the lipoplexes by DCs and the transfection efficiency.

The diagnostic management of recurrent deep vein thrombosis and pulmonary embolism.

The diagnostic management of recurrent venous thromboembolism (VTE) is a clinical dilemma. Clinical decision rules are well validated in patients with a first episode of clinically suspected VTE but are not validated in patients with a suspected recurrent event. D-dimer testing could safely exclude a recurrent VTE but is subject to several limitations.

Using an age-dependent D-dimer cut-off value increases the number of older patients in whom deep vein thrombosis can be safely excluded.

Background: D-dimer testing to rule out deep vein thrombosis is less useful in older patients because of a lower specificity. An age-adjusted D-dimer cut-off value increased the proportion of older patients (>50 years) in whom pulmonary embolism could be excluded. We retrospectively validated the efficacy of this cut-off combined with clinical probability for the exclusion of deep vein thrombosis.

Regional ecotoxicological hazards associated with anthropogenic enrichment of heavy metals.

Regional geochemical data of heavy metals are commonly used for environmental risk assessment and management. Often these data are based on so-called total concentrations, whereas the exposure to the mobile or reactive fraction of these elements finally determines whether the exposed ecosystem is at risk and to which extent. The objective of our research was to develop a wider applicable method for quantitative hazard assessment of soil metal contamination attributable to the activity of man, based on and illustrated with data from the Netherlands.

A widening health gap in general practice? Socio-economic differences in morbidity between 1975 and 2000 in The Netherlands.

Background: During the past two decades, socio-economic inequalities in health have been a major research theme in Western Europe. Research has shown that there are persistent differences in health between people with a high socio-economic status (SES) compared with people with a low SES. There are also indications for a widening health gap.

The effect of two ammonia-emission-reducing pig housing systems on odour emission.

Odour nuisance from agricultural activities is increasing in densely populated countries like the Netherlands. To develop adequate regulations, a large-scale, government-financed monitoring programme was started in the mid-1990s to establish odour emission levels for both conventional and low ammonia emission housing systems for cattle, pigs and poultry. The results indicate that high- and low-odour emission housing are difficult to distinguish because of the large variation within housing systems.

Odour and ammonia removal from pig house exhaust air using a biotrickling filter.

Odour from agricultural activities, such as the spreading of manure and the housing of animals, is increasingly being considered a nuisance in densely populated countries like the Netherlands. The objective of this research was to study the odour removal from pig house exhaust air by a biotrickling filter that had been implemented for ammonia abatement. At a regular pig production farm, the performance of a running full-scale biotrickling filter was studied for 72 days.

Impact of socioeconomic status on the course of rheumatoid arthritis and on related use of health care services.

Objective: To quantify the impact of socioeconomic status (SES) among patients with rheumatoid arthritis on 1) health outcomes and related health care utilization in relation to disease duration and 2) changes in health outcomes and related health care utilization over a 2-year period.

Methods: A questionnaire survey was conducted among 878 patients with rheumatoid arthritis (RA), varying in disease duration from 0 to more than 15 years. To determine the impact of SES on the health outcomes and health care use, patients were compared within and between 3 disease duration groups.

Environmental monitoring in the The Netherlands: past developments and future challenges.

During the past three decades environmental monitoring systems covering an immense variety of environmental problems emerged rapidly throughout the world. In The Netherlands the entire spectrum of monitoring systems is present. Their development is especially interesting because of the Dutch complex environmental landscape: a result of the combination of a natural setting with a high small-scale variation and an intense use of the available space by both industry and agriculture.

Three novel KCNA1 mutations in episodic ataxia type I families.

Hereditary paroxysmal ataxia, or episodic ataxia (EA), is a rare, genetically heterogeneous neurological disorder characterized by attacks of generalized ataxia. By direct sequence analysis, a different missense mutation of the potassium channel gene (KCNA1) has been identified in three families with EA.
